Replaced stale J-b waits in parent and W4. Proposed W8 owns current authorized Markdown/DOCX links/backlinks list, labels, versioned refresh, leakage refusals and fixture tests.

After: both locations explicitly put W8 landing before human opening as mos-1470 build order, not acceptance; comment/tracked-deletion links are not current story links and never appear in the human Connections view regardless of agent settings. New commit atop approved 5af060fb5, no amend. Static diff and append-only checks pass. Docs only, no repo Node/tests/live action. Fenton checks only this delta.

Draft after: exact root/mosaic/path with octal 0750 equivalence; stat/output unchanged; both verifies use cleaned-up bare scratch repos. Three additive-only test blocks, two planned mutants. Untested under Sage-3738; Sage-3740 authorizes untested branch push for static review. Queue row pending; Sage owns gate and landing.

AS_USER audit found git -C and stack-release's existing checkout cd cover the other steps. Added new unit and unreadable-cwd copy tests only. Untested under Sage's no-Node hold; no live action.
+
+2026-10-23 | Gladstone | #1816 / Vikunja 614 F5 draft (mos-1536) | Before: the run sheet omits the explicit notify decision and precheck misses a bus-start refusal. After: section 9a creates a private null-binding decision as mosaic; precheck directly reuses readNotifyConfig and private_dir, and new tests cover accepted and refused decisions. Existing fixture setup additions await Mos approval through Sage; installer unchanged. Untested under no-Node hold.

+# Row 239 round 1 verdict: honker/row239-r4 e0cb1db2c (duckworth-0295)
+
+Request: honker-0206 (in-review round 1, rev 3719). Candidate: e0cb1db2c on refactor 546366f4a.
+Method: git reads of local objects only. No node, no tests, no fetch, no queue reads.
+
+## Verdict: APPROVE
+
+- **The replay is exact.** `git range-diff 93694c518..5b8492b0f 546366f4a..0cae2dad5` gives four `=`
+  lines. None of the 16 manifest paths changed between 93694c518 and 546366f4a, and
+  `git diff 5b8492b0f 0cae2dad5` over those 16 paths is empty. My r3 read (REBASE-r3-5b8492b0f.md,
+  duckworth-0292) applies unchanged, and so do the 0165 design approval and the 0168 code approval with
+  C1 and C2 met.
+- **e0cb1db2c is doc only.** It appends 26 lines to agents/honker/work/queue-239/BUILD.md. No test reads
+  that file.
+- **Pins at e0cb1db2c.** All four 64-hex pins in channel-proof.test.mjs match the files' sha256:
+  human.mjs, human-cli.mjs, transport.mjs and webui bus.mjs (e3f52172…). Upstream changed library
+  src/index.mjs and business src/index.mjs, and no test or script pins them. The only hit in my grep
+  is a basename collision (`cli.mjs` matched `human-cli.mjs`).
+- **The run, as Honker reported it (sage-3773 CLEAR, on 0cae2dad5. I didn't rerun it):**
+  - The six touched test files ran whole: 65/65, 0 skipped, no first-run red.
+  - Mutants M1-M3g: 9/9 killed as assertion failures in their named tests.
+  - M3f killed T6, which matches my static trace in 0292.
+  - Every restore matched by sha256, and the tree was clean afterwards.
+  Running on the replay rather than r3's base was right, because bus runtime.mjs imports library
+  src/index.mjs and the cli imports business src/index.mjs, and both changed upstream.
+- **What remains is Sage's.** The full gate runs on the replay at landing (sage-3730). Sage's call.
+
+## Notes
+
+- None new. 0168 N1 (endsWith access-revoked) stands as recorded.

+# Hostcheck item 5 and bundle verification (Gitea #1816, Vikunja 614)
+
+Queue row pending from Sage. Owner Gladstone, reviewer Morgana, gate/landing Sage.
+Base: fetched origin/refactor 93694c5185d0a7f989d2fe78fb620e44599b744e;
+branch gladstone/hostcheck-item5. Scope: mos-1531 / ops-0256, sage-3738 and sage-3740.
+
+## Before and after
+
+Ubuntu 24.04 dpkg 1.22.6ubuntu6.6 prints `root mosaic 750 /usr/bin/bwrap`.
+Item 5 compared the literal `0750`, falsely refusing a correctly configured host;
+--enforce would unload the profile, close bwrap and record DRIFT.
+The candidate accepts exactly four fields, root, mosaic, octal 0750, and $BWRAP.
+`0*750` represents all octal spellings numerically equal to 0750 without arithmetic
+conversion/overflow. Horizontal whitespace separates fields; extra fields and
+embedded newlines refuse. Owner, group and path remain exact. The stat comparison
+and existing output strings remain unchanged. Only the item 5 comment also changes.
+
+The two release-transport bundle checks previously ran outside any repository.
+Each now creates an empty bare scratch repository, verifies with git -C, and removes
+the scratch directory using an EXIT trap. A failure exits the shell before cloning
+or fetching. No other run-sheet text changes.
+
+## Tests and mutants
+
+Only packages/cli/tests/case1-hostcheck.test.mjs changes among tests, by appending
+three new test() blocks; the existing passing 0750 fake and failing fake are intact.
+The pass test exercises 750, 0750 and 000750. The enforce test checks no unload,
+chown, chmod, DRIFT or hostcheck log for 750. Refusals independently cover 755,
+0755, 4750, 75, 7500, 075, non-octal strings, other owner/group/path, missing path,
+extra fields, multiple lines, blank/empty output and a missing fixture file.
+
+| Mutant | Change | Killer | Result |
+|---|---|---|---|
+| M1 | Restore the old literal root mosaic 0750 comparison (drop 750) | new check pass test | Unrun |
+| M2 | Accept any mode while preserving owner/group/path | new refusal test | Unrun |
+
+Mutant procedure: preserve script bytes, assert one replacement, run the named
+killer alone, require failure for its intended assertion, restore in finally and
+check the original bytes/hash. Run the original targeted file again after restore.
+
+## Verification status
+
+Untested. Sage-3738 prohibits all Node until CLEAR because the joint full gate
+runs alone. Sage-3740 explicitly directs pushing this untested build for Morgana's
+static review before CLEAR. This supersedes test-first execution for this draft;
+no Node, tests, node --check, full suites or live-host operations have run.
+Queue next refused linked-worktree execution; Sage owns queue creation/movement.
+Push only gladstone/*, with MOSAIC_GITEA_CREDENTIAL_FILE unset; no amend/force.
+
+Static draft receipt: `git diff --check` passed. Test-file numstat against the
+base is `46 0 packages/cli/tests/case1-hostcheck.test.mjs` (added/deleted).
+
+## Scope and implementation amendment (mos-1534, sage-3741)
+
+F1 correction: Sage requires precisely `750` or `0750` and exactly single spaces,
+so the candidate now uses `0?750` and literal spaces. It refuses 00750/000750,
+a doubled space and a tab. This supersedes the initial numeric-equivalence design
+above. Only this row's own appended tests change; no base test line changes.
+
+F3: case2-unit.sh plain() adds @. abs_plain is its only caller and requires an
+absolute normalized path, so @ cannot become an ExecStart prefix. In sed @ is
+ordinary replacement text (the delimiter is |); &, backslash and | still refuse.
+Environment=MOSAIC_CLAUDE_BIN carries @ literally; the parser compares the complete
+value, with no shell evaluation. @anthropic-ai also cannot match the residual
+@[A-Z_]+@ token check. Tests render/reinstall with a regular executable under
+@anthropic-ai, checking Environment and the new copy's WorkingDirectory. Since a
+nonroot test cannot create root ownership, a stat fake models root:0755 only for
+that file and its ancestor chain. The real file type/executable checks, render,
+installed-unit parser, and all other stat calls remain active. A separate block
+refuses space, %, $, both quote characters, backslash, & and |.
+
+F4: copy_tree changes to / before archive/npm/find, after all its path arguments
+are absolute. copy_bundle retains its existing relative-bundle resolution before
+calling copy_tree. Checkout copies have absolute REPO and COPIES too. Source-only
+use from stack-release.sh changes no cwd because copy_tree is not called there.
+Audit of every AS_USER command in stack-upgrade.sh: fetch and merge use git -C;
+plan, gate, revert, confirm-rollback, stage (activate/rollback), confirm and rehearse
+invoke stack-release.sh, which changes to its checkout at line 34. No other
+AS_USER command needs a fix. The new test enters a directory mode 0111, verifies
+that ls cannot read it, then runs both a relative-bundle copy and checkout copy,
+asserting success, no find restore error, and an immutable completed copy.
+
+Additional mutants (unrun under the same no-Node hold):
+
+| Mutant | Change | Killer | Result |
+|---|---|---|---|
+| M3 | Drop @ from plain() | new factory scoped Claude-path test | Unrun |
+| M4 | Remove copy_tree's cd / | new unreadable-cwd copy test | Unrun |
+
+All four fixes remain untested. Follow-up is an additive commit on the pushed
+branch, per sage-3741, with no amend or force. Morgana's static F1/F2 read of
+f30c74b12 was CLEAN (morgana-0205); F3/F4 and execution remain open.
+
+Morgana N1: the outer bundle-verification failure now prints
+`STOP: bundle verify failed; do not continue` instead of exiting the interactive
+root shell. The subshell still returns failure and cleans up. This follows the
+sheet's human read-and-stop convention and avoids sending remaining pasted lines
+to a parent shell after exiting sudo -i. Inner mktemp failure still exits only the
+subshell. This supersedes the initial outer-shell failure behavior noted above.

+## F5 (mos-1536 / ops-0260): explicit notifier decision
+
+Before: no run-sheet step creates the required notifier decision, and precheck
+accepts a host whose bus will refuse missing notify.json. After: section 9a
+requires the mosaic user to create its business notify directory at 0700 and an
+explicit {"notifyVersion": 1, "binding": null} file at 0600 before section 10.
+The shell runs with cwd / and umask 077; noclobber refuses an existing decision.
+Named binding is explicitly a later per-host choice requiring Mos's go.
+case2-install.sh is unchanged and makes no silent default.
+
+case2-precheck.sh's existing facts helper dynamically imports readNotifyConfig
+from cli.mjs and calls it directly. File type, uid, exact 0600 mode, JSON keys,
+version and binding-name validation therefore stay identical to the bus. The
+shell checks the business notify directory with existing private_dir (same uid,
+not a symlink, exactly 0700) and prints the new notifier config line. No notifier
+is started and no configuration is written. Tests append pass cases for null and
+a valid named binding, and refusal cases for missing file, 0644, 0755 directory,
+extra key, malformed JSON, invalid binding/version and a symlinked file.
+
+M5 (unrun): remove the notifier shell check, including its refusal branch; the
+new notifier refusal test must fail. Also include Morgana's F3 negative mutant
+M3b (allow $ in plain), killed by the new unsafe-character test.
+
+Existing positive precheck tests need an explicit notify fixture. Approval
+requested via Sage in gladstone-0006/-0007 for minimal setup-only additions to
+case2-unit.test.mjs host(t) and case2-install.test.mjs world(t); assertions remain
+unchanged. Those additions are not yet applied. Correction to gladstone-0007:
+case1-accept.test.mjs also names case2-precheck.sh, but uses a stand-in; it does
+not execute the changed script and needs no fixture amendment.
+
+Execution remains held by Sage: no Node/tests run. Morgana-0207 static F1-F4
+verdict on a75532db1 is CLEAN; execution and F5 review are still open.
+
+F5 acceptance from mos-1536 (for review):
+1. Before section 10, as mosaic, explicitly create <dataRoot>/notify/<business>
+   at 0700 and notify.json at 0600 with default binding null; a later named
+   binding needs Mos's go. Do not make case2-install.sh write it.
+2. Precheck must refuse missing file, non-0600 file, directory looser than 0700
+   and a document outside the CLI's exact shape. Reuse/match cli.mjs validation,
+   and name the new line in this run-sheet step's Precheck entry.
+3. Append-only test blocks cover pass, missing, 0644, 0755 dir, extra key; record
+   a skip-check mutant, the touched test file and its numstat.
+4. F3/F4 precede F5, each follow-up commit stays on gladstone/hostcheck-item5;
+   send pushes to Sage/Morgana with Mos cc. No Node until Sage CLEAR.
+
+Static F5 draft receipt: git diff --check passed. Existing fixture approvals
+remain pending; F5's new pass test creates its own explicit decisions. No claim
+that the old positive precheck tests pass without the pending setup changes.

+## Fixture approval and separate follow-up (mos-1537)
+
+Mos approved exactly setup-only additions to case2-unit.test.mjs host(t) and
+case2-install.test.mjs world(t): each gets three added lines for a 0700
+notify/acme directory and 0600 notify.json with {"notifyVersion":1,"binding":null}.
+No existing line, fake or assertion changes or is deleted. F5's missing-file
+negative case removes the file after setup, so the new default cannot mask it.
+The newly appended install test checks preserved bytes and mode after success,
+and separately removes the decision before install and checks it stays absent.
+case1-accept.test.mjs is unchanged. This follow-up is committed separately on
+33950cf9b as directed, with no amend. No Node/tests run; suite claims remain open.
+Morgana-0211 found F5 source/run sheet CLEAN statically; the setup prerequisite B1
+is addressed by this approved fixture patch, pending execution.
+
+Additional planned mutants from Morgana-0211 (unrun): M5b drops private_dir,
+killed by the directory fault; M5c prints NOTIFY ok unconditionally, killed by
+the document faults. Existing test preservation is checked by git diff showing
+only additions (numstat below).
+
+Fixture follow-up numstat: case2-unit.test.mjs +3/-0,
+case2-install.test.mjs +18/-0. Against the original base: case1-hostcheck.test.mjs
++48/-0, case2-unit.test.mjs +68/-0, stack-copy.test.mjs +16/-0,
+case2-install.test.mjs +18/-0. git diff --check passed.
+
+## F6 and notify parent correction (mos-1537 / ops-0261)
+
+Before: install creates a copy but no human CLI wrapper; the sheet's
+stack-copy.sh check --units external therefore fails even with correct units.
+After: the sheet explicitly places a wrapper step after successful install and
+before that check. On Mos's separate live-step go, mosaic changes cwd to /,
+creates $HOME/.npm-global/bin if absent, then invokes its clone's stack-copy.sh
+wrapper <sha> --create. Existing wrappers refuse and require review; install is
+unchanged. This is documentation of a gated host action, not execution of it.
+There are no tests pinning these sheet steps to adjust.
+
+Section 9a now explicitly creates/chmods <dataRoot>/notify and then its business
+leaf, each 0700. This addresses ops-0261's observation that mkdir -p -m only
+controls the leaf. The existing umask 077 remains. All exits are inside the
+unprivileged shell, so no failure exits the operator's interactive root shell.
+
+Static receipt: git diff --check passed. No Node, tests or live action. F6 and
+this parent-directory documentation correction are a separate commit after the
+approved fixture-only 5fd2328b6 follow-up. Reviewer should retain the earlier
+F1-F5 source verdicts and inspect this delta. Queue row still pending from Sage.

+## F6 gate citation (sage-3747)
+
+Added scripts/stack-copy.sh:3 to the F6 wrapper step's explicit Mos-go requirement.
+This is doc-only; commands and tests are unchanged. Sage ruled the delete-after-
+setup missing-file negative meets mos-1537, so no fixture change is needed.
+Morgana-0213 found the fixture/F6 deltas CLEAN statically. No Node/tests run;
+Morgana's eventual run waits for Sage's row and CLEAR after the 220+216 landing.
+Numstat for this follow-up: host-run-sheet.md +1/-1; BUILD.md +9/-0.
+Static receipt: git diff --check passed.
+
+Correction: 0f3d874d4 added 10 BUILD.md lines, not 9; the git numstat is authoritative.
+
+## First review run and F4 test correction (morgana-0217)
+
+Morgana ran af201b4a9 (6fa47e07d only relocates this file) under her authorized
+slot with timeout -k 10 and TMPDIR under /mnt/storage/scratch/tmp. Receipts:
+/mnt/storage/scratch/morgana-g320-out/base-summary.txt and mutants-summary.txt.
+
+| Targeted file | Passed | Failed |
+|---|---:|---:|
+| case1-hostcheck.test.mjs | 19 | 0 |
+| case2-unit.test.mjs | 47 | 0 |
+| case2-install.test.mjs | 24 | 0 |
+| stack-copy.test.mjs | 17 | 1 |
+
+Seven of eight mutants were killed: M1 literal0750, M2 anymode, M3a drop@,
+M3b allow$, M5 drop shell block, M5b drop private_dir, M5c always NOTIFY ok.
+M4 drop cd / SURVIVED: base and mutant both failed only setup's cleanup hook.
+This is a test defect, not a green acceptance result. The 0111 cwd retained
+search permission and did not reproduce the inaccessible inherited cwd. It
+also blocked setup's chmod -R cleanup because the directory remained unreadable.
+
+B1 correction touches only this row's appended F4 test: the child shell enters
+an initially searchable directory, chmods it 000, checks both ! -r and ! -x, then
+execs stack-copy. The parent asserts all read/search bits remain cleared. The
+bundle now lives outside cwd and is passed absolutely, matching the real flow;
+existing row232 coverage still tests relative bundles from an accessible cwd.
+Both bundle and checkout paths remain covered.
+B2 correction: each child run/assertion sequence has a finally that restores the
+cwd to0700 before setup's existing cleanup. No old setup/test lines change.
+Production scripts are unchanged; the cd / fix remains correct by static review.
+
+Correction is untested locally: no builder Node/test CLEAR was given. Morgana
+will rerun stack-copy whole, M4 and residue cleanup on the pushed correction;
+other files need no rerun unless changed. git diff --check passed.

+# Goldie
+
+Builder seat, Codex gpt-6.1-sol, started by Sage under mos-1542 and mos-1546. Owns F8 and F9, the library persona
+import in `scripts/case2-install.sh` (#1818), for the 433 Run B rerun.
+
+No launcher in this directory. The seat runs as a T3 thread and works in its own worktree. It has no credentials of its
+own; it pushes only its own `goldie/*` branches through the repository credential helper (mos-0981), never `refactor`,
+`main` or another seat's branch. Claude seats orchestrate and review the install path (mos-1542 rule 4). Registered by
+Sage on 2026-10-23 so the queue can name the seat as row owner (store.mjs isSeatDir).

+# Row 322 / #1818 — F8 and F9
+
+Goldie, 2026-10-23. Branch goldie/row322, base 833ec1cc8d7c11842efb82e57c1a0b256c8d22d7.
+Brief: docs/plans/2026-10-23_host-fixes-1816-brief.md, F8/F9 section at 7333f94ba9cf.
+Issue #1818 is supplied by Sage; no new issue is needed. Reviewer Morgana; Sage owns landing/full gate.
+
+## Implementation and authority
+
+F8 runs the importer from `$COPIES/$COMMIT/scripts/case2-persona-import.mjs`. This uses Node's normal ESM resolution, finding yaml beside the copy and the relative harness module in that same commit. It avoids a custom loader or ambient resolution setting. The copy closure already includes harness/src and business/src, but omitted the importer itself; COPY_PATHS now includes that one script. No new dependency or dependency version change.
+
+F9 selects the first line beginning with an Error type (including TypeError etc.) or ERR_, falling back to the last line for the importer's handled refusal. awk exits after the first matching line and emits exactly one line, keeping the stack and version banner out of the install refusal. Anchoring avoids selecting Node's earlier `throw new ERR_MODULE_NOT_FOUND(...)` source excerpt instead of the actual Error line.
+
+Mos-1550 authorizes the copy-path addition, setup-only additions to world(t), and adding the single new filename to any existing copy-file pin. Existing test edits outside the appended row-322 block:
+
+- case2-install.test.mjs: the fake stack-copy setup gains a loop copying the importer, harness bundle.mjs/tools.mjs, and business vocabulary.mjs; it copies yaml into the fake copy's node_modules. The existing last template-string line is extended to add those setup commands. No existing assertion changes.
+- packages/webui/tests/pinned-copy.test.mjs:76: the scripts file-list assertion gains only `case2-persona-import.mjs`, in sorted order. No other change in this test.
+
+The new append-only block builds a scratch clone outside the repository with no node_modules, real installer and importer, stubbed bootstrap/business validation, and a copy with the real importer, relative module closure and yaml. F8 checks installed persona bytes/mode; F9 removes yaml from that copy to produce a real uncaught Node missing-package error, then checks one refusal line carries the cause and no stack/banner. Existing tests missed F8 because the real importer ran from the development checkout, which has yaml installed; the fake copy held only scripts/mosaic. The old fixtures thus never exercised the dependency boundary or an uncaught importer load error.
+
+## Class check and copy-test audit
+
+Before change:
+
+```
+grep -n 'node "$REPO/' scripts/case2-install.sh scripts/case2-precheck.sh scripts/stack-copy.sh
+scripts/case2-install.sh:185:        out="$(node "$REPO/scripts/case2-persona-import.mjs" ...
+```
+
+After change: same grep has no hits (exit 1). Direct clone-side .mjs entry points in the three scripts with a bare package import: **scripts/case2-persona-import.mjs → yaml**, moved to the copy by F8. No other direct entry point imports a bare package. Precheck's inline Node programs dynamically import cli/src/config.mjs, business/src/index.mjs, library/src/index.mjs and cli/src/cli.mjs; those entry files import builtins/relative modules only. Library reader.mjs uses its own front-matter parser and has no yaml import. stack-copy sources instance.sh, whose mosaic-config.mjs imports builtins only. Installer bootstrap likewise runs mosaic-config.mjs, and business validation runs business/src/cli.mjs, also no direct bare imports. No other product fix made.
+
+Audit commands (read-only):
+
+```
+rg -n 'COPY_PATHS|copy carries|copy.*(hash|sha256|files|file set)|sha256.*copy' packages/*/tests/* scripts/test-*.sh
+rg -n 'COPY_PATHS|stack-copy\.sh|readdirSync|sha256|deepEqual' packages/webui/tests/pinned-copy.test.mjs packages/cli/tests/stack-copy.test.mjs
+```
+
+Relevant hits: cli/tests/stack-copy.test.mjs:35-47 checks harness file closure (positive control: COPY_PATHS at :36), :52 asserts a required-file subset, :248-264 computes hashes/modes and compares bundle/check-out copy trees dynamically, :274 compares another bundle tree. None freezes a complete path list/hash. webui/tests/pinned-copy.test.mjs:75 pins top-level entries (unchanged), :76 pins scripts' exact file set (approved one-path update). Other readdir hits in those files check cleanup/existing-target behavior, not COPY_PATHS identity. Broad initial grep also hits business/tests/helpers.mjs:33, cli/tests/stack-upgrade.test.mjs:295, webui/tests/views.test.mjs:172, cli/tests/stack-release.test.mjs:1751 and :1987; inspected contexts are unrelated comments/UI copy or different fixture copies. No scripts/test-*.sh hit for these path/hash patterns.
+
+## Verification plan
+
+Pending Sage CLEAR before any test: run new tests on fixed build first, then whole case2-install.test.mjs, whole stack-copy.test.mjs and webui pinned-copy.test.mjs. Demonstrate expected failure at 094124b4e with new block applied (baseline importer path), and kill the `$REPO` reversion mutant. Record all outcomes. First unexpected new-test red is recorded/reported under mos-1272; existing-test edits outside mos-1550 or a second unexpected red stop for Sage.
+
+No tests run yet. No commit/push yet. No host changes, live state, secrets, deploy or release actions.
+
+## Verified results — sage-3808 CLEAR, 2026-10-23T22:47Z
+
+All runs were serialized with `TMPDIR=/mnt/storage/scratch/tmp/goldieuQ2664` (created by `mktemp -d /mnt/storage/scratch/tmp/goldieXXXXXX`), using `timeout -k 10 90` for focused tests and `timeout -k 10 180` for whole files/negative-proof driver. Node v26.8.1. Dependencies were read through the ignored, uncommitted node_modules symlink approved by sage-3804; each scratch clone had no node_modules. No /tmp fixture was used.
+
+| Run | Result | Evidence |
+| --- | --- | --- |
+| New tests, first run | 2/2 pass, exit 0 | test-new.log |
+| Whole case2-install.test.mjs | 26/26 pass, exit 0 | test-install.log |
+| Whole stack-copy.test.mjs | 18/18 pass, exit 0 | test-copy.log |
+| Whole webui pinned-copy.test.mjs | 10/10 pass, exit 0 | test-pinned-copy.log |
+| Installer from 094124b4e, new tests | 0/2 pass, exit 1, expected red | baseline-094124b4e.log |
+| F8 mutant: restore `$REPO` importer path only | 0/1 pass, exit 1, killed | mutant-F8.log |
+| F9 mutant: restore tail-only refusal only | 0/1 pass, exit 1, killed | mutant-F9.log |
+| Fixed installer restored, new tests rerun | 2/2 pass, exit 0 | test-restored.log |
+
+The baseline proof temporarily installs the exact installer bytes from `git show 094124b4e:scripts/case2-install.sh`, retaining the newly appended tests and approved fixture setup. Relevant installer/importer/copy/test source paths have no changes between N and the branch base 833ec1cc8 (`git diff 094124b4e 833ec1cc8 --` those paths is empty). It is a targeted baseline proof, not a full checkout/suite run at N. Baseline failures show `persona-import: Node.js v26.8.1`; the F8-only mutant exposes the underlying `Error [ERR_MODULE_NOT_FOUND]: Cannot find package 'yaml'` from the scratch clone. F9-only mutant again prints the banner. All expected failures are deliberate acceptance checks; no unexpected first-run red occurred.
+
+negative-proof.py records each run, checks the expected failure count/exit, restores in a finally block, and verifies fixed installer bytes after each run. Restored SHA-256 each time: `c23a08324528cc29895014093c661948a5c8eb40316c7b2e21c6f833cf5d6462`. Final focused green confirms restoration. git diff --check passed.
+
+`git diff --numstat -- packages/cli/tests/case2-install.test.mjs`: **57 additions, 1 deletion**. Outside the new appended block, original line 70's template-string close moves after four new setup lines: the existing mkdir/empty mosaic/echo command is unchanged, followed by the `for file ...` line, mkdir/cp loop body, `done`, and mkdir/cp yaml line. All pre-existing assertions remain byte-for-byte unchanged. The only pre-existing assertion edit anywhere is the expressly approved one-filename addition at packages/webui/tests/pinned-copy.test.mjs:76.
+
+Sage's full package/script gate and Morgana's review remain pending. This builder ran only the approved three whole test files and targeted acceptance checks. Sage retains queue transition/review posting and integration authority; no PR was created by Goldie.
+
+Evidence log lines have trailing whitespace removed for git diff --check; test content and outcomes are unchanged.

+# Row 226 build notes, C2-13b install script and library precheck (#1727)
+
+Brief: docs/plans/2026-10-20_case2-rows.md "C2-13b install script and library precheck" (:1073-1134 at
+d37210288). Design: agents/gosalyn/work/case2/DESIGN.md r11 sections 4 and 10, on gosalyn/case2-design
+75fb3e10e. Row 195's needs: agents/darkwing/work/queue-195/DESIGN.md "What row 195 needs from row 226".
+
+This is design round d2. Nothing is built yet. d1 was f46e66883, and Webby's review of it is webby-0085
+(CHANGES, B1 and N1-N6) and webby-0086 (the ordering problem). Sage ruled on both in sage-2189. The
+changes from d1 are listed at the end.
+
+## Base
+
+Branch gosalyn/c2-13b from refactor d37210288. Rows 215, 221, 222 and 230 are done.
+
+## Facts the design rests on
+
+- No CLI writes a business file. `mosaic business validate <id>` checks one and exits 0 ok, 2 invalid
+  (packages/business/src/cli.mjs). A business file needs `human`, `arbiters`, `projects`, `tracker`
+  with a sync bot and a Vikunja credential ref, and `roles`, each role with its tracker bot when its
+  definition uses Vikunja (business.mjs:23, :84-100, :131-149).
+- The library is a project, `projects.<id>.kind === "library"`, checked by `checkMapping`
+  (packages/library/src/mapping.mjs). There is no top-level `library` key.
+- `library.sync` and `library.status` are bus verbs, human only (broker.mjs:92, :2452-2476). The only
+  client is `packages/bus/src/human-cli.mjs` over the bus socket.
+- The bus makes each library mirror at start, `ensureMirror({ business, project, dataRoot })`
+  (packages/bus/src/runtime.mjs:143-145). Before the bus first starts there is no mirror.
+- `sync()` fetches outside `withLibraryLock`. Only a per-process `running` set keeps two syncs apart
+  (packages/library/src/sync.mjs:97-98), so a second process calling `sync()` would race the bus's
+  timer.
+- `libraryStatus(context)` reads the recorded state under the flock and writes nothing
+  (mirror.mjs:232-239). A missing or unsafe mirror fails `library-git` (`ownedRoot`, mirror.mjs:43-49).
+  A mirror that has never synced returns the empty state, `lastFetch: null`, `lastError: null`,
+  `problems: []` (mirror.mjs:27, :205-210). `lastError` is `{ code, at }` with `code` matching
+  `^[a-z-]{1,64}$` (mirror.mjs:225).
+- The bus builds the library context as `{ business, project, dataRoot }` and the slot as
+  `<slotDir>/secrets/<business.id>/library-gitea` (runtime.mjs:146-151, :162-164).
+- `case2-persona-import.mjs install --staging DIR --config-dir DIR --business ID` writes
+  `<configDir>/personas/<business>/<instance>.md` at 0600 in 0700 dirs, never overwriting, and prints
+  `instance bean: persona.name Bean, persona.sha256 <hex>` per persona.
+- A Discord binding is `<dataRoot>/discord/<name>.json` (packages/discord/src/binding.mjs:70-83).
+- `case2-unit.sh --copy ID` needs `<home>/.local/share/mosaic-stack/copies/<ID>`, which
+  `stack-copy.sh copy COMMIT --copies DIR` makes. The copy runs `npm ci` from package-lock.json
+  (stack-copy.sh:70), which installs the pinned pi.
+
+## Design
+
+### D1. The business file is an input
+
+Unchanged from d1. `case2-install.sh` takes `--business-file FILE`, a JSON business document written for
+the host from Jason's go. The script doesn't build one from flags, because bots, botIds and credential
+refs are host values and the brief says every host value is an input. It checks the input, adds what
+only it knows, writes it, and then runs `mosaic business validate`, so business.mjs stays the only
+schema.
+
+What the script checks before it writes anything, beyond `validate`:
+- `id` equals `--business`.
+- `library`: at least one library project, `bus.tester` not true, roles `bean` and `chet` with
+  definition `companion`, and no `persona.*` var in the input, since D3 adds them.
+- `factory`: no library project, and `bus.tester` true. These are the precheck's rules at
+  case2-precheck.sh:127-135, so the install refuses what the precheck would refuse.
+
+### D2. Install steps, in order
+
+1. Refuse to run as root.
+2. `scripts/bootstrap.sh`. It's idempotent and never rewrites an existing config.
+3. `scripts/stack-copy.sh copy <--commit> --copies <home>/.local/share/mosaic-stack/copies`. The copy
+   `case2-unit.sh --copy` names has to exist before root renders the units (row 195 need 3).
+4. `library` only: the persona import's `install` step from `--personas DIR` (D3).
+5. Write `<configDir>/businesses/<id>.json` at 0600 with O_EXCL (D4).
+6. `library` only: make `<configDir>/secrets/<business>/` at 0700, empty. The token is Jason's, design 10
+   step 4.
+7. `mosaic business validate <id>`. If it refuses and step 5 created the file in this run, remove that
+   file, then refuse. A file that already matched on a re-run (D4) is never removed (N4).
+8. Print the copy id and the next steps: root's 2c, Jason's 2d, 3 and 4, then the `--library-status`
+   check (D6b).
+
+d1's step 3, `release.sh package` and `activate`, is gone (Q4a, webby-0085 B1, sage-2189). Package is a
+`docker compose build`, and activate runs a pi Compose health check that mounts `PI_AUTH_FILE`
+(compose.yaml:43). Neither fits 2a, which has no Docker and no pi credential, and the hub doesn't run
+containers. The pinned harness comes from the copy's `npm ci` (Q3). The `CASE2_RELEASE` seam goes with
+it.
+
+It starts no unit, writes no unit file, doesn't write `/etc/mosaic-stack/dev.args` and doesn't run
+`adopt`. These are my answers to row 195's needs 4 and 5 (gosalyn-0087), unchanged. Row 195's W8 now
+passes `--business-file` and has no release step.
+
+### D3. Personas come from the staging dir
+
+Unchanged from d1. `library` requires `--personas DIR`, the staging dir from `case2-persona-import.mjs
+stage`. The install runs `case2-persona-import.mjs install --staging DIR --config-dir <configDir>
+--business <id>` and reads its two `instance` lines into `roles.bean.vars` and `roles.chet.vars`. Only
+those two lines go into the business file. They hold a name and a digest, never text.
+
+This moves the persona import's stage part of design 10 step 6 ahead of 2b: the read of her Hermes
+profiles and Jason's check of the printed pairing. Webby agreed in webby-0085 (Q1).
+
+### D4. Re-runs
+
+Unchanged from d1, plus N4. Each step is safe to run again. bootstrap and the copy are idempotent. An
+existing business file that matches the one the script would write passes, and the script remembers it
+didn't create it. One that differs refuses `business-file-differs`, and the script doesn't touch it.
+The persona import already refuses to overwrite. On a re-run the install compares each existing
+persona file's sha256 with the staging manifest, and refuses on a mismatch.
+
+### D5. Inputs and seams
+
+```
+case2-install.sh --business ID --business-file FILE --commit SHA [--profile factory|library]
+                 [--personas DIR] [--home DIR]
+```
+
+`--home` defaults to `$HOME`, which is `/srv/mosaic` under `sudo -u mosaic -H`. `MOSAIC_CONFIG` is
+honoured as bootstrap.sh honours it. One test seam, in case2-unit.sh's `CASE2_*` pattern:
+`CASE2_STACK_COPY` is the copy script, and the test uses a stub that makes the copy dir.
+
+Exit codes: 0 ok, 1 refused, 4 usage, as case2-unit.sh uses.
+
+### D6. Precheck library checks, split in two (Q4b, sage-2189)
+
+d1 ran `sync()` from the precheck. Webby's N1 and webby-0086 showed two faults. The precheck runs before
+the units start, so there is no mirror yet (runtime.mjs:143-145). And a precheck `sync()` after the bus
+is up would race the bus's timer, since `sync()` fetches outside the lock (sync.mjs:97-98). Sage split
+the check in sage-2189, and the brief's "runs library.sync" becomes "reads the bus's recorded sync
+state".
+
+#### D6a. Before the units start, `--profile library`
+
+These run where the precheck runs today, after 2c's render and before the start. They sync nothing and
+read no mirror. Each is a `refuse` line in the script's style.
+- The business file is owned by the uid, with no group or other bit (`business-file-mode`).
+  `businesses/.history/<id>/` is 0700 and its `changes.jsonl` is 0600, when present (`history-mode`).
+- The persona dirs are 0700. Each creative role's persona file is regular, owned and 0600
+  (`persona-mode`), and its sha256 equals the role's `persona.sha256` (`persona-mismatch`). The output
+  prints names and digests, never text.
+- No `<dataRoot>/discord/*.json` exists (`discord-binding`).
+
+#### D6b. `case2-precheck.sh --business ID --library-status`, after the bus is up and after step 4
+
+A new mode, run as `<user>` once the bus is up and Jason has placed the token. It changes nothing. A
+node block builds the context the bus builds, `{ business, project, dataRoot }` for each library
+project, with `dataRoot` from the config (N3, runtime.mjs:146-151, :162-164). For each one it:
+- refuses `library-mirror-missing` when the mirror path doesn't exist. It checks this itself, so the
+  message says the bus hasn't made it, not `library-git`;
+- calls `libraryStatus(context)` only, and refuses with the thrown code when that fails, for example
+  `library-git` for an unsafe mirror or `library-sync-busy` when the flock wait runs out;
+- refuses `library-never-synced` when `lastFetch` is null;
+- refuses `library-last-error <code>` when `lastError` is not null. The code is the fixed
+  `^[a-z-]{1,64}$` string, so it's safe to print. This also covers Webby's N2;
+- prints each recorded R-problem as `problem   R<n> <path>`, with the path through `JSON.stringify`, then
+  one `problems  <count>` line (N5). Her file names are the only part that prints, never text.
+  R-problems don't refuse (Q2, agreed by Webby).
+
+The bus syncs each library with a `user` every 60 s, so the first run after step 4 may need a minute,
+or Jason's own `library.sync`. The run sheet says so.
+
+### D7. host-run-sheet.md fix
+
+`docs/guides/host-run-sheet.md:240` says "I2's install writes it" about `dev.args`. It becomes: root
+writes it at the unit render, from the values the go names, and the install never writes it, because
+`<user>` can't write `/etc` and root reads nothing `<user>` wrote. Sage asked in sage-1832 for this fix
+to go in this build commit, with its path in the manifest. Section 9's `library-gitea` line (:275) says
+"C2-13b's `library.sync` (not landed)". It becomes the `--library-status` check (D6b). The install
+section also gets a line that the copy's `npm ci` needs the npm registry from the host (Q3, webby-0085).
+
+### D8. Design 10 text
+
+Sage ruled that design 10 gets the same change when 226 lands, with the line in this row's manifest.
+In agents/gosalyn/work/case2/DESIGN.md:
+- step 2b drops `release.sh package` and `activate`;
+- a new step after step 4 runs `case2-precheck.sh --business <business> --library-status`;
+- the precheck's library text says it reads the bus's recorded sync state, not that it runs
+  `library.sync`.
+
+### D9. Tests, `packages/cli/tests/case2-install.test.mjs`
+
+These follow case2-unit.test.mjs: scratch HOME, MOSAIC_CONFIG, stub bin dir and seams, a local bare repo
+cloned `--bare --no-local` as sync.test.mjs does, and the fixture's key never in output.
+- Install `library`:
+  - writes the business file at 0600 with bean's and chet's persona vars;
+  - writes the persona files at 0600 in 0700 dirs and the empty slot dir at 0700;
+  - logs the copy call and no release call;
+  - starts nothing;
+  - passes on a re-run;
+  - refuses `business-file-differs` and leaves the file unchanged.
+- Install `factory`:
+  - writes no library mapping, no persona file and no slot dir, which is the brief's case;
+  - refuses a library project and `bus.tester` off.
+- Install refuses: run as root, a business id mismatch, missing `--personas` under library, and a
+  `validate` refusal, after which no business file is left.
+- N4: a re-run where the matching business file is already there and `validate` refuses leaves that
+  file in place, byte for byte.
+- D6a refusals, one case each: a persona file at 0644, a digest mismatch, a business file at 0644, a
+  `changes.jsonl` at 0644, and a Discord binding. A clean library host passes D6a with no mirror.
+- D6b, with the mirror made by `ensureMirror` and the state written by a real `sync()` against the local
+  bare repo, as the bus would:
+  - no mirror refuses `library-mirror-missing`;
+  - a fresh mirror refuses `library-never-synced`;
+  - a sync against a remote that doesn't resolve refuses `library-last-error` with its code;
+  - a synced bare repo with one R2 path prints its `problem` line and `problems  1`, and passes.
+
+Every new refusal gets a mutant that removes it. The count goes in the slot request.
+
+### D10. Files
+
+Owned by the brief: `scripts/case2-install.sh` (new), `scripts/case2-precheck.sh` (library checks and
+`--library-status` only) and `packages/cli/tests/case2-install.test.mjs` (new). Also
+`docs/guides/host-run-sheet.md` (D7, sage-1832), agents/gosalyn/work/case2/DESIGN.md (D8, sage-2189)
+and this BUILD.md. Before the slot request I'll grep for outside readers of case2-precheck.sh, since
+case2-unit.test.mjs runs it.
+
+## Questions
+
+All three d1 questions are settled:
+- Q1, persona stage before 2b: Webby agreed (webby-0085).
+- Q2, R-problems don't refuse: Webby agreed.
+- Q3, the pinned harness is the copy's `npm ci`: Webby agreed, and asked for the registry note in D7.
+- Q4a and Q4b: Sage, sage-2189.
+
+One choice for Webby to check: D6b's `problem` line carries the path through `JSON.stringify`. N5 asked
+for a prefix and a count. I kept the path because Jason needs it to tell her which file to fix, and the
+names are hers, not text.
+
+## Changes from d1
+
+- B1: release package and activate dropped, with the `CASE2_RELEASE` seam and its test (D2, D5).
+- N1 and webby-0086: the sync is gone from the precheck. D6 splits into D6a before the start and D6b,
+  `--library-status`, after the bus is up and step 4 (sage-2189).
+- N2: covered by D6b's `lastError` refusal.
+- N3: D6b builds the context and slot as the bus does.
+- N4: step 7 removes only a file this run created, with a test.
+- N5: `problem` prefix and a `problems` count.
+- N6: the run sheet lines are :240 and :275.
+- New D8, the design 10 text change, and its path in D10.

+## Build
+
+Webby approved d2 in webby-0087 (REVIEW-design-d2.md, webby/reviews 2f488b4ea). Nothing above this
+section changed after approval. This section records the build.
+
+### D8 lands on case2-design
+
+Sage ruled in sage-2195, after Webby's N1, that D8 goes on gosalyn/case2-design, because
+agents/gosalyn/work/case2/DESIGN.md isn't on refactor. The change is commit 624212842 there, pushed:
+step 2b drops `release.sh package` and `activate`, new step 4a runs `--library-status`, and the C2-13b
+row text says the precheck reads the bus's recorded sync state. DESIGN.md is not in this row's manifest.
+
+The brief's lines docs/plans/2026-10-20_case2-rows.md:1093-1096 still name release package, activate and
+a library.sync fetch. Sage owns the brief and will amend those lines to match D8 in a doc-only commit
+after the re-pin window (sage-2205). They are not in this row's manifest.
+
+### Webby's d2 notes
+
+- N2: the `problem` line keeps the path. After `JSON.stringify` the precheck also escapes DEL, the C1
+  controls U+0080-009F, U+200E and U+200F, U+2028 and U+2029, and the bidi controls U+202A-202E and
+  U+2066-2069 as `\uXXXX`. Webby named C1 and bidi. I added the rest because `JSON.stringify` leaves
+  them raw too, and each one can change how a terminal shows the line. The test path holds U+202E and
+  U+0085, and the test checks that neither prints raw.
+- N3: `lastError` is checked before `lastFetch`. A first sync with no token records
+  `library-credential-missing` and leaves `lastFetch` null, so it refuses `library-last-error`, not
+  `library-never-synced`. The fresh-mirror test has `lastError` null and refuses `library-never-synced`.
+
+### Choices made in the build
+
+- The config dir. The persona import refuses a config dir with group or other bits, and bootstrap makes
+  one with the default mode. So the install makes the config dir at 0700 when it's absent, before
+  bootstrap, and refuses `config-dir-mode` when it exists with a group or other bit. It checks
+  `secrets/` and `secrets/<id>/` the same way under library (`secrets-mode`, `slot-mode`).
+- `--home` must equal `$HOME` (`home-mismatch`). Every path comes from `$HOME` and `MOSAIC_CONFIG`, as
+  bootstrap's does, so a different `--home` would only name a second home the script doesn't use.
+- A plan step runs before anything is written. It reads the input and the staging manifest, computes
+  the persona vars from the manifest, and compares the result with what's on disk. It refuses every
+  input rule, `business-file-differs` and `persona-differs` there, so a refused run writes nothing.
+  After the import the script checks that the import's two `instance` lines carry the manifest's
+  digests.
+- A re-run with both persona files present and matching skips the import, which would refuse to
+  overwrite them. One matching file and one missing refuses `persona-differs`.
+- A diverged library prints one line under `--library-status`, naming the tip `library.sync --accept`
+  would take. It doesn't refuse. The design doesn't list it as a refusal, and the bus still serves the
+  old tip.
+- The precheck's library checks print `ok` lines for each check they pass, as the rest of the script
+  does. A business file that's missing prints no extra line, since the existing business-file check
+  already refuses it.
+- The business id must match the persona import's rule, `^[a-z0-9][a-z0-9-]{0,63}$`. That's narrower
+  than the precheck's, which also takes `.` and `_`, because the persona dir uses the id.
+
+### Outside readers
+
+`git grep` over packages/*/tests/*, packages/*/src/* and scripts/test-*.sh finds case2-precheck.sh read
+by case2-unit.test.mjs, which runs it, and case1-accept.test.mjs, which names a copy's path but runs a
+fake. No test reads host-run-sheet.md. No test pins a hash of either script. case2-unit.test.mjs's
+precheck host has a 0600 business file and no persona vars, so the new D6a checks pass there.
+
+### Mutants
+
+24, in /mnt/storage/scratch/gosalyn-r226/mutate.py. Each replaces one exact string once. Line numbers
+are the candidate's. run.sh stops with BASE RED before any mutant unless the base run is rc=0 and
+fail 0.
+
+| Mutant | Line | Check removed |
+|---|---|---|
+| I1 | install :73 | run-as-root |
+| I2 | install :74 | home-mismatch |
+| I3 | install :81 | config-dir-mode |
+| I4 | install :101 | business-id-mismatch |
+| I5 | install :107 | profile-library-business |
+| I6 | install :108 | bus-tester-off |
+| I7 | install :111 | bus-tester-on |

+| I9 | install :158 | business-file-differs |
+| I10 | install :152 | persona-differs |
+| I11 | install :218 | N4, removes the file even when this run didn't write it |
+| I12 | install :218 | validate's removal of the file this run wrote |
+| P1 | precheck :229 | business-file-mode |
+| P2 | precheck :235 | history-mode for changes.jsonl |
+| P3 | precheck :246 | persona-mode for a persona file |
+| P4 | precheck :251 | persona-mismatch |
+| P5 | precheck :241 | persona-mode for a persona dir |
+| P6 | precheck :258 | discord-binding |
+| P7 | precheck :104 | library-mirror-missing |
+| P8 | precheck :107 | library-last-error |
+| P9 | precheck :107 | N3, the order swapped |
+| P10 | precheck :108 | library-never-synced |
+| P11 | precheck :92 | N2, the escape after stringify |
+| P12 | precheck :65 | --library-status refuses --profile |
+
+`history-mode` for the history dir itself has no mutant and no test. The brief names only the
+`changes.jsonl` case.

+# Row 239 (#1745) build notes (append only)
+
+## 2026-10-22 b1 (Honker)
+
+Design d1 5da5f28f6 was approved by Duckworth with C1 and C2 and no blockers (duckworth-0165, note
+agents/duckworth/work/row239/REVIEW-design-d1.md). The code is on honker/row239 from aca16404c. No test
+has run yet: every run waits for Sage's CLEAR.
+
+### Duckworth's conditions and answers
+
+- C1 (option a): `outcome-unknown-revoked` is in the Console's `OPEN` list (webui bus.mjs), so
+  `sendOutcome` answers it as `outcome-unknown` with `sent: 'unknown'` and never "Nothing changed". T6
+  covers it and M3f is its mutant.
+- C2: `write()` sets `revoked = true` after `beforeWrite()` returns, and a catch around the whole
+  `withLock(...)` call marks the error. So a throw from the lock's release in its finally is marked as
+  well. This is structural and has no test, as Duckworth said.
+- Q1: `beforeWrite` runs after both validations. Q2: two codes. Q3: M2 removes the `:188` check (now
+  organization.mjs:195).
+
+### Notes N1-N5
+
+- N1: `beforeWrite` must not write the same business, because it would find its own lock and refuse
+  `organization-busy`. This is said in the comments on `write()` and `commit()`. Today's revokes (the
+  bus's credential revoke) write no business file.
+- N2: the lock is held across the revoke. A fire or a delete now keeps other writers of that business
+  out for as long as the revoke takes. They refuse `organization-busy`, as they do for any held lock.
+- N3: a revoke that fails partway (some tokens revoked, then `credential-revoke-failed`) behaves as
+  today. The error carries no `revoked` mark, because `beforeWrite` didn't return, and nothing is
+  written. This row doesn't change that.
+- N4: a delete closed with `outcome-unknown-revoked` exits 3 in the CLI, as every closed refusal does.
+  Exit 1 (transport EXIT) applies only to a direct verb answer.
+- N5: I grepped for "before the write" and similar comments. The ones left (lifecycle-revoke.test:2,
+  instance-settings:56, cli instances.mjs:53, serve.mjs:365) are still true and are unchanged. T21 in
+  bus lifecycle-revoke.test:173 is unchanged.
+
+### Differences from the design
+
+- The business tests are in lifecycle-settings.test.mjs, not instance-settings.test.mjs. The fire tests
+  and their fixture already live there. The fixture now returns `dir` and `rolesDir` too.
+- T3 covers T3b (the delete) in the same test, looping over fire and delete. It also checks that a
+  revoke throwing `credential-revoke-failed` carries no mark and writes nothing.
+- T4b is the plain-code check. The design's "T4b, outcome-unknown-revoked for an fs-style error" is in
+  T4, which checks EIO with and without the mark for both a fire and a delete.
+- The bus test's fake org gets `deleteError`, thrown from its `instances.set` branch, so T4 can drive a
+  delete.
+- transport.test gets one assertion, `busExit("outcome-unknown-revoked") === 1`, for M3g.
+- A latent Console text: a direct (not closed-request) `revision-conflict-revoked` answer in the
+  Console would still get " Nothing changed." appended, because only `OPEN` codes skip it. That sentence
+  is true there: the file is unchanged. No direct human path gives this code today, since a delete
+  reaches the Console as a closed request's refusal.
+- The Console's STATUS entry for `outcome-unknown-revoked` (503) can't be reached while the code is in
+  `OPEN`. It stays for symmetry with the CLI and is harmless.
+
+### What changed
+
+- packages/business/src/organization.mjs: `write()` takes `beforeWrite`, runs it under the lock after
+  the revision check and both validations, and marks any later error `revoked`. The body is reindented
+  inside the try.
+- packages/business/src/instance-settings.mjs: `instanceSettings` takes an optional `writer`. `commit()`
+  passes `beforeWrite` to `writer.write` instead of calling it. The early check stays, and its comment
+  is rewritten.
+- packages/bus/src/broker.mjs: `#organizationFail` maps a marked error to `revision-conflict-revoked` or
+  `outcome-unknown-revoked` before the existing mappings. `#fireJob`'s notice adds "Its credential
+  tokens may already be revoked." for a `-revoked` code.
+- packages/bus/src/runtime.mjs: comment only.
+- packages/cli/src/instances.mjs: two REASONS entries. packages/cli/src/transport.mjs: EXIT
+  `outcome-unknown-revoked` 1.
+- packages/webui/src/serve.mjs: two AGENT_REASONS entries. packages/webui/src/bus.mjs: `OPEN` entry and
+  two STATUS entries.
+- Tests:
+  - business lifecycle-settings.test: "row 239 T1", "row 239 T2", "row 239 T3".
+  - bus fire-revokes-grants.test: "row 239 T4", "row 239 T4b".
+  - cli instances.test: "row 239 T5 CLI". cli transport.test: one assertion in "busExit and
+    refuseInsideAgent".
+  - webui agents.test: "row 239 T6".
+  - bus channel-proof.test re-pins packages/cli/src/transport.mjs (662642a8...) and
+    packages/webui/src/bus.mjs (1eba9774...), with a comment on each. Neither changes a proof or the
+    transport. The design's file list missed this. The pin grep found it before the first run.
+### Mutants for the gate (exact-once replacements)
+
+- M1 (instance-settings.mjs, beforeWrite before the lock): replace
+  `    const receipt = writer.write(business, next, { revision, actor, context, beforeWrite });` with
+  `    if (beforeWrite) beforeWrite();\n    const receipt = writer.write(business, next, { revision, actor, context });`.
+  The kill is lifecycle-settings "row 239 T1" (the revoke spy has a call).
+- M2 (organization.mjs, the fire refusal dropped): delete the line
+  `        if (revision !== before) fail("revision-conflict", "organization revision changed; read again");`.
+  The kill is "row 239 T1" (the write lands over the hand edit).
+- M3a (organization.mjs, the mark dropped): `      if (revoked && e instanceof Error) e.revoked = true;`
+  becomes `      void revoked;`. The kills are "row 239 T2" and "row 239 T3" (business). T4 drives the mark
+  through a fake org, so it doesn't see M3a.
+- M3b (broker.mjs): delete the line
+  `    if (e.revoked) fail(e.code === "revision-conflict" ? "revision-conflict-revoked" : "outcome-unknown-revoked");`.
+  The kill is fire-revokes-grants "row 239 T4".
+- M3c (cli instances.mjs): delete the five lines from `  "revision-conflict-revoked": "the business file`
+  through `    "business file again with \`mosaic business instances\` before trying again",`. The kill is
+  instances.test "row 239 T5 CLI".
+- M3d (webui serve.mjs): delete the two lines starting `  'revision-conflict-revoked': 'the business file`
+  and `  'outcome-unknown-revoked': 'the agent\'s tokens`. The kill is agents.test "row 239 T6".
+- M3e (broker.mjs): `      const tokens = code.endsWith('-revoked') ? ' Its credential tokens may already be revoked.' : '';`
+  becomes `      const tokens = '';`. The kill is "row 239 T4".
+- M3f (webui bus.mjs, C1): the `OPEN` line loses `, 'outcome-unknown-revoked'`. The kill is "row 239 T6"
+  (the launch POST answers 503 outcome-unknown, sent unknown).
+- M3g (cli transport.mjs): delete the line `  "outcome-unknown-revoked": 1,`. The kill is transport.test
+  "busExit and refuseInsideAgent".
+
+A kill counts only as a failed assertion in the named test, not a load error or a different test.
+
+### Gate plan (mos-1275 timeouts)
+
+- My row 256 gate (2026-10-22 10:34Z, same machine) took 590s for the cli package, 57s for webui and
+  38s for test-foundation, the longest shell script.
+- Packages: `timeout -k 10 1800` per package (3x the cli run).
+- Each scripts/test-*.sh: `timeout -k 10 300` (more than 3x the 38s longest).
+- Single files and mutants: `timeout -k 10 600` per file run (cli instances.test whole is the longest
+  single file).
+- Order on Sage's CLEAR: the touched test files whole (business lifecycle-settings, bus
+  fire-revokes-grants and channel-proof, cli instances and transport, webui agents), then M1-M3g, then
+  the full gate.
+- Before the in-review move: grep packages/*/tests for the changed comment and error text and for
+  64-hex pins on the changed files, and drift-check BASE..refactor against them.
+
+## 2026-10-22 r2 rebase (Honker)
+
+- Duckworth approved b1 b0c28366f statically, with no blockers (duckworth-0168). On N1 (`endsWith('-revoked')`
+  would also match `access-revoked`, which can't reach a fire job today), the check stays as it is, so the
+  approved candidate doesn't change before the gate (honker-0163).
+- Rows 253 (48e450ce8) and 275 landed. b1 is rebased onto refactor 94c33a43c as honker/row239-r2. The
+  push branch honker/row239 isn't rewritten.
+- Drift between aca16404c and 94c33a43c on the 15 paths: only packages/bus/src/broker.mjs, where row 275
+  changes the viewer verbs. Neither of row 239's two hunks (`#fireJob` and `#organizationFail`) moves in
+  meaning. The rebase applied with no conflict. The two pinned files (cli transport.mjs, webui bus.mjs)
+  and channel-proof.test have no upstream change, so the b1 pins stand.
+- Each M1-M3g replacement string still matches exactly once.
+- The touched test files run whole again on the new base, in the slot (the rebase rule).
+
+## 2026-10-23 r3 rebase (Honker, sage-3730)
+
+- r2 (70c6e3772) is rebased onto refactor 93694c518 as honker/row239-r3. honker/row239-r2 isn't rewritten.
+- Between 94c33a43c and 93694c518, five of the 16 paths changed upstream: bus broker.mjs and runtime.mjs,
+  channel-proof.test, and webui bus.mjs and serve.mjs. Every file merged on its own except channel-proof.test,
+  where row 301 (59f0e44f4, mos-1449) re-pinned webui bus.mjs for the user transport fold. The merged
+  pin keeps row 301's comment and row 239's, and takes sha256 e3f52172…1c2a89 of the merged bus.mjs.
+  The transport.mjs pin (662642a8…6e55b) still matches the file.
+- Row 239's hunks in broker.mjs (`#fireJob`, `#organizationFail`), runtime.mjs (the revoke comment),
+  bus.mjs (OPEN, STATUS) and serve.mjs are unchanged apart from their position. The range-diff shows
+  only the channel-proof pin and the hunk context moved.
+- Each M1-M3g replacement string still matches exactly once. M3f's target is the whole `OPEN` line,
+  since `, 'outcome-unknown-revoked'` also appears in the STATUS line.
+- No 64-hex pin in packages/*/tests or scripts names a changed file except channel-proof.test.
+- On the CLEAR (sage-3730): the touched files whole, then M1-M3g, then the counts here. Sage runs the
+  full gate on the replay at landing.
+
+## 2026-10-23 r4 replay and the slot run (Honker, sage-3773 CLEAR)
+
+- On the CLEAR, refactor was 546366f4a (row 320 landed at 094124b4e). None of the 16 manifest paths changed
+  between 93694c518 and 546366f4a. Upstream did change library src/index.mjs, which bus runtime.mjs imports,
+  and business src/index.mjs, which the cli imports, so the run was on a replay onto 546366f4a rather than
+  on r3's base. That replay is honker/row239-r4 0cae2dad5. The range-diff of r3 against r4 is four `=`
+  lines with equal patch-ids, so duckworth-0292's read of r3 applies to r4. r3 isn't rewritten.
+- The run was on 0cae2dad5 with a clean tree, TMPDIR under /mnt/storage/scratch/tmp, 22:01:27Z-22:01:52Z.
+- The touched files, run whole: business lifecycle-settings 12/12, bus fire-revokes-grants 24/24, bus
+  channel-proof 2/2, cli instances 15/15, cli transport 3/3, webui agents 9/9. That's 65/65 with 0 skipped,
+  and no first-run red.
+- Mutants: 9 of 9 killed. Each was applied exactly once, and each made its named test fail as an assertion:
+  - M1 lifecycle: 3 fail (T1, T2, T3).
+  - M2: T1.
+  - M3a: T2 and T3.
+  - M3b fire-revokes-grants: T4.
+  - M3c instances: T5 CLI.
+  - M3d agents: T6.
+  - M3e: T4.
+  - M3f agents: T6.
+  - M3g transport: "busExit and refuseInsideAgent".
+
+  T4b passed under M3b and M3e. Every restore matched the HEAD blob by sha256, and the tree was clean
+  after the run.
+- No full gate (sage-3730): Sage runs it on the replay at landing.

+# Row 239 design: the revoke under the writer's lock, and a fire test
+
+Brief: docs/plans/2026-10-20_agent-lifecycle.md, "Brief: row 194 follow-up, the revoke under the writer's
+lock and a fire test" (blob 3b3b3b2b9), from Duckworth's row 194 b3 N1 and mos-1158. Base aca16404c (row
+194 landed as fd6dd327c, row 281 as e479521d3). Builder Honker, reviewer Duckworth, gate owner Sage.
+Draft 1, 2026-10-22.
+
+## Today
+
+- `instance-settings.mjs` `commit()` runs the checks, then compares the caller's revision with a fresh
+  `writer.read` (row 194 b3, sage-1634), then calls `beforeWrite` (the fire's or the delete's credential
+  revoke), then `writer.write`.
+- `writer.write` (`organization.mjs`) takes the lock, runs `recover`, checks the revision again (`:188`),
+  validates, prepares, checks the bytes once more before publication (`:221`), renames and commits.
+- So two windows are left.
+  - A write that lands between `commit()`'s read and the writer's lock still gets a revoke and then a
+    `revision-conflict`.
+  - Any refusal after the revoke ran (the `:221` check, or an I/O failure the bus reports as
+    `outcome-unknown`) uses the same text as one before it, so nothing says the tokens may be gone.
+- Row 281 left this path alone. Its fire job (`broker.mjs` `#fireJob`) runs step G (grants), then step B,
+  which is this same `write('instance.fire')`, and reports a step B failure as `fire.failed` along with a
+  human notice that names the code. Its delete job only does step G. The delete itself still commits
+  through `lifecycleDelete` → `instances.set` op delete → `commit()`.
+
+## What changes
+
+### 1. `beforeWrite` runs inside `writer.write`, under the lock (organization.mjs)
+
+`write(id, document, { revision, actor, detail, context, beforeWrite = null })`. The order under the lock:
+
+1. `recover`, read, then the `:188` revision check. A refusal here revokes nothing.
+2. Projects-protected and both validations. A refusal here revokes nothing either. I put `beforeWrite`
+   after these rather than straight after `:188`, so a document the writer would refuse anyway never
+   costs a revoke. Q1 asks Duckworth to confirm this.
+3. `beforeWrite()`. If it throws (today `credential-revoke-failed`), the error propagates as it is and
+   nothing has been written, as now.
+4. Prepare, the `:221` check, rename and commit, wrapped so that any error thrown after step 3 gets
+   `revoked = true` set on it before it is rethrown. That covers `revision-conflict` from `:221`, an
+   `organization-refused` from `log()`, a barrier throw, and an fs error.
+
+`record()` and the other writers (`launch-settings`, `plugin-settings`, `credentialVerbs`) pass no
+`beforeWrite` and behave as before.
+
+### 2. commit() passes beforeWrite through (instance-settings.mjs)
+
+`commit()` passes `beforeWrite` to `writer.write` and no longer calls it itself. The row 194 b3 early check
+stays. It costs one read, keeps T21's refusal before any validation work, and is no longer what protects
+the revoke. Its comment is rewritten to say so, and the "(BUILD.md follow-up)" sentence goes.
+
+`instanceSettings({ ..., writer = organizationWriter({ dir, rolesDir }) })` takes an optional writer, so a
+test can inject one (the brief's "injected writer"). `runtime.mjs` passes none.
+
+### 3. The bus names a refusal after a revoke (broker.mjs `#organizationFail`)
+
+The bus answers with a code only, and the CLI and Console look the text up by code. So the "may already be
+revoked" signal has to be a code. Two new codes:
+
+- `revision-conflict-revoked`: `e.revoked && e.code === 'revision-conflict'`.
+- `outcome-unknown-revoked`: `e.revoked` with any other code. The write may or may not have landed, since a
+  failure after the rename is recovered as committed.
+
+Both are checked before the existing mappings. An error without `revoked` maps exactly as today, so a
+refusal before any revoke keeps today's code and text. Q2 asks about the names.
+
+### 4. The texts
+
+- CLI `instances.mjs` REASONS:
+  - `revision-conflict-revoked`: "the business file changed before the write, after the agent's tokens
+    were revoked; the tokens may already be revoked and the instance can't use them; read the instances
+    again and run the same command again, which is safe".
+  - `outcome-unknown-revoked`: "the write's outcome is unknown and the agent's tokens may already be
+    revoked; read the instances before trying again".
+- Console `serve.mjs` AGENT_REASONS: the same two, in the Console's wording ("delete again").
+- `#fireJob`'s `fire.failed` notice: when the code ends in `-revoked`, it adds "Its credential tokens may
+  already be revoked." The chief's synchronous fire (no grants) answers with the code, as every chief verb
+  does.
+- `transport.mjs` EXIT: `outcome-unknown-revoked` exits 1, as `outcome-unknown` does. Console
+  `bus.mjs` STATUS: `revision-conflict-revoked` 409, `outcome-unknown-revoked` 503. A delete's code
+  reaches both as a closed request's `refusal`, so these two only matter for a direct verb answer.
+
+## Tests
+
+- **T1, the brief's fire test** (business `instance-settings.test.mjs`). The fire uses an injected writer
+  that wraps the real one. Its `write` makes one hand edit of the business file (a vars change on another
+  instance) and then calls the real `write`, so the edit lands after `commit()`'s early check and before
+  the lock's `:188` check. Expected:
+  - the fire refuses `revision-conflict` without `revoked`;
+  - the revoke spy has no calls;
+  - the business file's bytes are the hand edit's;
+  - changes.jsonl has no new prepared entry.
+- **T2** (same file). A fire on a real writer built with `barrier: stage => stage === 'prepared' && edit()`.
+  The revoke runs, then `:221` refuses. Expected: `revision-conflict` with `revoked === true`, one revoke
+  call, the file's bytes are the edit's, and the last receipt is `aborted`.
+- **T3** (same file). The same, with a `prepared` barrier that throws. Expected: the error has
+  `revoked === true`, one revoke call, and the file unchanged. A delete through the same writer gives the
+  same result (T3b).
+- **T4** (bus `fire-revokes-grants.test.mjs`, its injected `f.org`). `f.org.fireError` is a
+  `revision-conflict` with `revoked: true`. Expected:
+  - the job's `fire.failed` carries `revision-conflict-revoked`, and the inbox message says "may already
+    be revoked";
+  - the same with no `grants` (the synchronous fire) refuses `revision-conflict-revoked`;
+  - a plain `revision-conflict` still maps to `revision-conflict` and the message lacks the sentence.
+  - T4b: `outcome-unknown-revoked` for an fs-style error with `revoked`.
+- **T5** (cli `lifecycle.test.mjs` or `instances.test.mjs`, whichever already reads a closed delete's
+  refusal). A delete closed with `revision-conflict-revoked` prints the new text, and one closed with
+  `revision-conflict` prints today's.
+- **T6** (webui `agents.test.mjs`). The same pair for the Console's reason.
+- T21 (bus `lifecycle-revoke.test.mjs`) stays as it is, for delete.
+
+## Mutants
+
+| Mutant | Change | Killed by |
+| --- | --- | --- |
+| M1 | `beforeWrite` before the lock: `commit()` calls `beforeWrite()` itself and passes none to `write` | T1 (the revoke spy has a call) |
+| M2 | The fire refusal dropped: the `:188` revision check removed | T1 (the write lands over the hand edit) |
+| M3a | The mark dropped: no `revoked = true` in the catch | T2, T3, and T4 through the codes |
+| M3b | `#organizationFail` ignores `revoked` | T4 |
+| M3c | CLI text: the two REASONS entries removed | T5 |
+| M3d | Console text: the two AGENT_REASONS entries removed | T6 |
+| M3e | The notice: the `fire.failed` sentence removed | T4 |
+
+M3a-M3e together are the brief's "drop the may already be revoked text".

+
+## Gate
+
+As the brief says:
+
+- Duckworth approves the manifest.
+- The bus, business, cli and webui suites and every `scripts/test-*.sh` are green on Sage's slot, with
+  the touched test files run whole.
+- M1-M3e are killed.
+
+Before the in-review move I grep the tests for the changed comment and error text, and for hash pins on the
+changed files.
+
+## Questions for Duckworth
+
+- **Q1.** Should `beforeWrite` run after the writer's validations (my pick) or straight after `:188` (the
+  brief's literal place)? Running it later means a document the writer would refuse revokes nothing.
+- **Q2.** Are two new codes, `revision-conflict-revoked` and `outcome-unknown-revoked`, the right way to
+  carry the signal? The alternative is to give `BusError` a detail field, which every CLI and Console
+  reader would then have to learn. The codes are additive and no existing code changes meaning.
+- **Q3.** The brief's mutant "drop the fire refusal": I read it as removing the `:188` check (M2). If you
+  meant the fire test's own refusal, say so and I'll redefine it.

+# Row 283 (#1788) C2-01d build notes (Honker)
+
+Append-only. Design: DESIGN.md d2 16e809457, APPROVE webby-0172. Gate owner Sage, reviewer Webby.
+
+## 2026-10-23 build on 45dca69f6 (sage-3577)
+
+Branch honker/row283-build from origin/refactor 45dca69f6e4bce52834587f66f2ff33ba839ab8a. The old branch
+honker/row283 (16e809457) held only the design, so its two commits were cherry-picked as 398314cf4
+(d1) and 4f66dccde (d2). The DESIGN.md blob equals 16e809457's.
+
+Commits:
+- 331653b38: code, README and tests T1-T8.
+- 28918824c: the survey.test:73 re-pin, alone (mos-1330 item 4).
+- this file.
+
+Nothing has run. No node, test or mutant ran during the build: Darkwing held the slot. Every count
+below is a plan until Sage's CLEAR.
+
+### Drift check (sage-3577)
+
+`git diff --stat 94c33a43c 45dca69f6` (design base to build base) over the paths the tests read or
+hash-pin:
+- No change in packages/library, packages/business/src/business.mjs or
+  packages/business/tests/business.test.mjs.
+- No test hash-pins a library file. bus library.test and library-sync.test import index.mjs, and
+  stack-copy.test only checks that index.mjs exists.
+- webui library-cli.test changed one line and doesn't read scope. The `classify` in webui reads.mjs is
+  the business one, not the library's.
+
+I redo the drift check on BASE..refactor before the in-review move.
+
+### N3 (webby-0169): deepEquals of the mapping output outside packages/library
+
+`git grep -n playground -- 'packages/*/tests/*' ':!packages/library/*'` and the files naming
+`universes` give two files:
+- business.test.mjs:20 compares `validateBusinessDocument(...).projects.books` with
+  `checkMapping(mappingEntry())`. That is output against output, so `supporting: []` shows up on both
+  sides. :27 compares only `.playground`.
+- library-projects-protected.test.mjs compares file bytes (:31, :32) and change paths (:58), never the
+  mapping output.
+
+No re-pin is needed outside library. Inside library, only the draft deepEqual at mapping.test:48 gains
+`supporting: []`, as the design says.
+
+### Q1 departure (sage-2923) and the :73 re-pin (mos-1330 item 4)
+
+survey.mjs:65 counts `supporting: 0` and formatSurvey prints it. T8 is the only added test
+(survey.test "C2-01d: with --mapping the survey counts supporting files").
+
+mos-1330 item 4, packages/library/tests/survey.test.mjs:73, commit 28918824c:
+- old: `'scopes canon 5, playground 1, unmapped 3; indexed 6',`
+- new: `'scopes canon 5, playground 1, supporting 0, unmapped 3; indexed 6',`
+
+N2: the pin gains only `supporting 0`. No other text on the line or in that test moved.
+
+### Q2 tradeoff (webby-0169)
+
+A supporting prefix that holds a playground prefix refuses `library-mapping-invalid`. That goes past
+the brief, but it is the fail-closed reading, and it uses an existing code: classify checks supporting
+first, so that playground prefix could never match. The cost is that she can't nest a playground under
+a supporting folder, though she can nest the other way (a playground holding a supporting folder).
+
+### Handoffs
+
+- Q4 (webby-0169, sage-2930): the M12 delete rule ("A delete also needs the path to exist at the tip as
+  a 100644 blob", case2 DESIGN.md :308) is not in supportingPath. It binds row 288 (C2-02) via Gitea
+  #1793 comment 30738, with tests for a missing path and a non-100644 entry.
+- A save with no `editor` refusing is C2-02's (DESIGN.md section 1).
+
+### Choices the design left open
+
+- The book loop is now `againstBooks(owners, list, code)` in mapping.mjs, called once per list. The
+  playground's messages and codes are byte-equal to before.
+- A non-string path refuses `library-write-story-path` ("the path must be a string") as part of
+  check 1. A non-array `tree` is a TypeError (DESIGN.md section 3).
+- Check 8 builds the tree's names as every path and every folder above it, keyed by
+  `normalize('NFC').toLowerCase()`. A name on the way refuses if its key holds any name other than
+  itself, so a tree that already holds case twins refuses a write to either (R7).
+
+### Mutants (exact strings)
+
+Each applies one replacement to the build tip. Run one at a time, and restore with `git checkout --`
+on the one file before the next.
+
+| Mutant | File | Replace | With | Killed by |
+|---|---|---|---|---|
+| M1 | src/scope.mjs | `const prefix = entry.supporting.find(p => inside(p, path));` | `const prefix = entry.supporting.find(p => inside(p, path) && !entry.playground.some(q => inside(q, path)));` | scope.test "supporting comes before playground", supporting.test "passes at book level" (both-lists path) |
+| M2 | src/mapping.mjs | `if ((inside \|\| holding) && owner !== id)` | `if ((inside \|\| holding) && owner !== id && list !== 'supporting')` | mapping.test "each supporting prefix rule", business.test C2-04 |
+| M3 | src/supporting.mjs | `for (const p of own) if (LINKS.has(modes.get(p)))` | `for (const p of own) if (false && LINKS.has(modes.get(p)))` | supporting.test "symlink or gitlink" |
+| M4 | src/supporting.mjs | `const fold = name => name.normalize('NFC').toLowerCase();` | `const fold = name => name.normalize('NFC');` | supporting.test "case or Unicode form" |
+| M4b | src/supporting.mjs | `const fold = name => name.normalize('NFC').toLowerCase();` | `const fold = name => name.toLowerCase();` | supporting.test "case or Unicode form" (NFD case) |
+| M5 | src/supporting.mjs | `Buffer.byteLength(path, 'utf8') > MAX_BYTES` | `path.length > MAX_BYTES` | supporting.test "1025 bytes" |
+| M6 | src/mapping.mjs | `const IDENT_BAD = /[\u0000-\u001f\u007f-\u009f<>]/;` | `const IDENT_BAD = /[<>]/;` | mapping.test "editor is optional" |
+| M6b | src/mapping.mjs | `const IDENT_BAD = /[\u0000-\u001f\u007f-\u009f<>]/;` | `const IDENT_BAD = /[\u0000-\u001f\u007f-\u009f]/;` | mapping.test "editor is optional" |
+| M7 | src/supporting.mjs | `if (place.scope !== 'supporting' \|\| place.universe !== universe)` | `if (place.scope !== 'supporting')` | supporting.test "outside the universe's supporting folders" |
+| M8 | src/mapping.mjs | `if (sid === pid && s !== p && holds(s, p))` | `if (false && sid === pid && s !== p && holds(s, p))` | mapping.test "each supporting prefix rule" (Workshop case) |
+
+(The `\|` in the table is an escaped `|` in the source text.) Each mutant runs the one test file named,
+plus business.test for M2, under `timeout -k 10 600`. A mutant passes the gate only when its run is red
+on the named test and the restored file's sha256 equals the build tip's.
+
+### Gate plan (on Sage's CLEAR)
+
+1. The touched files whole, each under `timeout -k 10 600`: library mapping, scope, supporting and
+   survey tests, and business.test.mjs. Counts go below.
+2. M1-M8 as above.
+3. The full gate, under mos-1275 timeouts: `node --test packages/library/tests/` and
+   `node --test packages/business/tests/` each under `timeout -k 10 1800`, and every scripts/test-*.sh
+   under `timeout -k 10 300`. pipefail and tee, with skips named (test-task Docker groups).
+4. Before in-review: grep packages/*/tests for a 64-hex pin on any changed file and for the changed
+   message text, then the drift check on BASE..refactor.
+
+## 2026-10-23 Webby early look (webby-0227, static, not a verdict)
+
+- E1: business.test.mjs is an existing test file with a 4-line addition after the playground refusal.
+  The in-review request lists it next to survey.test:73.
+- E3 fixed: supportingPath now runs the string check before `JSON.stringify`, so a BigInt (or any
+  non-string) path refuses `library-write-story-path` instead of throwing a TypeError.
+  supporting.test's string case now covers 7, null, undefined, 1n and an array.
+- E2 open: `editor` takes surrounding whitespace, and git trims it at commit, so the saved ident and
+  the commit ident can differ. DESIGN.md section 1 says "non-empty after trim". Refusing
+  `value.trim() !== value` would change that approved rule, so it went to Sage instead of into the
+  build.
+
+## 2026-10-23 E2 departure (sage-3601)
+
+A departure from DESIGN.md section 1 (which stays unedited). The design says each `editor` value is
+"non-empty after trim". Sage ruled that surrounding whitespace refuses too, because git trims an
+ident at commit, so a padded value would save one name and commit another. mapping.mjs now adds
+`if (value.trim() !== value) bad(`editor.${key} must not start or end with whitespace`)` after the
+IDENT_BAD check. `trim()` covers Unicode whitespace, so U+00A0 and U+3000 refuse as well. Inner
+whitespace is kept ("Her  Middle Name" passes).
+
+T3 gains a case per key for leading, trailing and both-ends spaces, U+00A0 and U+3000, plus one inner
+whitespace pass.
+
+M6 grows a third part:
+
+| Mutant | File | Replace | With | Killed by |
+|---|---|---|---|---|
+| M6c | src/mapping.mjs | `if (value.trim() !== value) bad(` | `if (false && value.trim() !== value) bad(` | mapping.test "editor is optional" (padded cases) |
+
+Fixture grep: `git grep -nE "\beditor\b|\bauthor\b" -- 'packages/library/tests/*' 'packages/business/tests/*'`,
+leaving out mapping.test.mjs, finds nothing. packages/business/tests has no fixtures directory. The
+library fixture mapping.json has no `editor`. The positive control (`vaultPrefix` in mapping.json)
+matches once. No fixture maps an editor or author with surrounding whitespace.
+
+## 2026-10-23 E4 (webby-0230, sage-3606), same departure as E2
+
+Claimed: `queue move 283 in-progress`, op honker-283-start, rev 3642, 19:10:49Z (briefed→in-progress).
+
+Git's ident.c `crud()` strips any byte <= 0x20 and `, : ; < > " \ '` from both ends of an ident. I
+checked that with git 2.55.0: `Jane,` `"Jane"` `'Jane'` `Jane;` `Jane:` `Jane\` and `,Jane` all
+commit as `Jane`, while `Jane.` and `Ja,ne` are kept. mapping.mjs now takes the set from crud()
+rather than from that list: `IDENT_CRUD_END = /^[\u0000-\u0020,:;<>"\\']|[\u0000-\u0020,:;<>"\\']$/`.
+The E2 check became `if (value.trim() !== value || IDENT_CRUD_END.test(value))`, which refuses
+library-mapping-invalid with "editor.<key> must not start or end with whitespace or any of , : ; " ' \".
+`trim()` still catches Unicode whitespace (U+00A0, U+3000), which crud() leaves alone.
+
+Inner characters: IDENT_BAD (`/[\u0000-\u001f\u007f-\u009f<>]/`) already refuses `<`, `>`, newline,
+tab and every other control anywhere in the value. T3 now pins that at the start, the end and the
+middle. Inner `, : ; " ' \` are kept, since git keeps them, and T3 pins that too.
+
+Tests:
+- T3 has one case per character in [space, U+00A0, U+3000, `,`, `:`, `;`, `"`, `'`, `\`], at the start
+  and at the end, for each key. `<`, `>`, newline and tab are pinned at the start, end and middle.
+  Four accepted names have inner crud characters.
+- New round-trip test, "an accepted editor round-trips through a real git commit unchanged". It
+  commits in a scratch repo with editor `Doe, Jane Q.` / `[email protected].` as author and
+  committer, with GIT_AUTHOR_* and GIT_COMMITTER_* stripped from the env, and asserts `git log`
+  shows exactly the saved values. I preflighted that commit with git 2.55.0 by hand: both values came
+  back unchanged.
+
+M6c now replaces the whole end check (this supersedes the earlier M6c row):
+
+| Mutant | File | Replace | With | Killed by |
+|---|---|---|---|---|
+| M6c | src/mapping.mjs | `if (value.trim() !== value \|\| IDENT_CRUD_END.test(value))` | `if (false)` | mapping.test "editor is optional" (end cases) |
+| M6d | src/mapping.mjs | `if (value.trim() !== value \|\| IDENT_CRUD_END.test(value))` | `if (value.trim() !== value)` | mapping.test "editor is optional" (`,` `:` `;` `"` `'` `\` cases) |
+
+## 2026-10-23 E5 (webby-0236, not blocking), fixed
+
+The round-trip test stripped only GIT_AUTHOR_* and GIT_COMMITTER_*. With GIT_DIR, GIT_WORK_TREE or
+GIT_INDEX_FILE set (inside a hook, say), GIT_DIR beats `-C root` and the commit would land in the
+outer repo, and the test read global and system config. It now deletes GIT_DIR, GIT_WORK_TREE,
+GIT_COMMON_DIR and GIT_INDEX_FILE (as queue/tests/helpers.mjs gitEnv does) and sets
+GIT_CONFIG_GLOBAL=/dev/null and GIT_CONFIG_NOSYSTEM=1 (as ledger.test.mjs does). The `-c user.*`
+ident still applies. Test only; no mutant changes.
+
+## 2026-10-23 sage-2925: optional editor.user (sage-3649)
+
+sage-2925 (recorded in ludwig/row286-r2 agents/ludwig/work/queue-286/BUILD.md, Q4) ruled that row 283
+adds an optional `editor.user`, her Gitea login for the `library-human` slot, which row 288 (C2-02)
+passes to `humanCredential(context, {user})`. It reached this row after the DESIGN.md d2 approval
+(ludwig-0068, bubba-0009, sage-3649), so it departs from DESIGN.md section 1 ("exactly the keys
+`name` and `email`"). DESIGN.md stays unedited.
+
+- mapping.mjs: `only(entry.editor, ['name', 'email', 'user'], 'editor')`. When present, `user` must be
+  a string matching USER (`/^[A-Za-z0-9_.-]{1,100}$/`, the entry `user` check), else
+  library-mapping-invalid "editor.user must be a plain account name". The output carries `user` only
+  when given. An absent `editor.user` refusing library-human-missing is 288's (bubba-0009).
+- README: the `editor` line names `user` and the end-character rule from E2/E4.
+- Tests: T3 (mapping.test "editor is optional") gains one accepted case (`her.login-1`, kept in the
+  output) and refused cases for '', an inner space, '@', 101 characters, 7 and null. They go in
+  mapping.test with the other editor cases, not in the new supporting.test, which tests write paths.
+- No test outside mapping.test reads `editor` or pins mapping.mjs or README (git grep).
+
+| Mutant | File | Replace | With | Killed by |
+|---|---|---|---|---|
+| M6e | src/mapping.mjs | `if (Object.hasOwn(entry.editor, 'user') && (typeof entry.editor.user !== 'string' \|\| !USER.test(entry.editor.user)))` | `if (false)` | mapping.test "editor is optional" (editor.user refusals) |
+| M6f | src/mapping.mjs | `...(Object.hasOwn(entry.editor, 'user') ? { user: entry.editor.user } : {})` | `...({})` | mapping.test "editor is optional" (`her.login-1` kept) |
+
+## 2026-10-23 T2 run (sage-3695 CLEAR, lane A, library and business only)
+
+Node v26.8.1. refactor was e2b873390 (226 landed); `git diff --stat 45dca69f6 e2b873390 -- packages/library
+packages/business` is empty. TMPDIR was a mktemp -d under /mnt/storage/scratch/tmp, with pipefail.
+Singles and mutants ran under `timeout -k 10 600`, suites under `timeout -k 10 1800`.
+
+First-run red (mos-1272, placed): the first base run on 46bad7ea3 at 20:01:09Z was red in
+supporting.test "malformed paths refuse by class, in order". 5 of 6 passed, with `TypeError: Do not know
+how to serialize a BigInt`. The cause was the test helper, not the product: `refuses()` labelled each
+assertion with `JSON.stringify(path)`, and the 1n case added for E3 can't be stringified. In c18ad3e12
+the label uses `util.inspect(path)`, a 2-line test-only change. The product's 1n refusal was never in
+question: supportingPath type-checks before it stringifies (E3). The whole run below is on c18ad3e12.
+
+Base, the touched files whole (20:01:43Z), all rc=0:
+- library mapping.test 16/16, scope.test 6/6, supporting.test 6/6, survey.test 7/7;
+- business business.test 21/21;
+- 0 skipped, 0 cancelled, 0 todo.

+|---|---|---|---|
+| M1 | scope.test | rc=1, 5/6 | supporting comes before playground; a folder in both lists is supporting… |
+| M1 | supporting.test | rc=1, 5/6 | a path passes at book level, universe level, in a draft and in a folder in both lists |
+| M2 | mapping.test | rc=1, 15/16 | each supporting prefix rule refuses with its code |

+
+14 of 14 mutants killed, each on its named test only.
+
+Suites (20:01:47Z):
+- `packages/library`: `node --test tests/*.test.mjs` rc=0, 98/98, 0 skipped.
+- `packages/business`: `node --test tests/` rc=0, 231/231, 0 skipped.
+
+Not run here: every scripts/test-*.sh and the other packages. Those are Sage's 283 gate, after Webby's
+APPROVE.
+
+## 2026-10-23 G1: mos-1528 OK for the mapping.test draft deepEqual (sage-3713)
+
+This entry completes the N3 line above (BUILD.md:42, "only the draft deepEqual at mapping.test:48 gains
+`supporting: []`"). BUILD.md is append-only, so :42 stays as written. Mos OK'd the change of that old
+assertion in mos-1528. It is now at packages/library/tests/mapping.test.mjs:52, and commit 331653b38
+changed it. Everything else in that commit's hunk is new test lines, not changed old ones.
+
+- Old, mapping.test.mjs:48 at 45dca69f6:
+  `assert.deepEqual(m.universes.idea, { kind: 'draft', name: 'New World', books: [], playground: ['Drafts/New World/'] });`
+- New, mapping.test.mjs:52 at b2a1f4092:
+  `assert.deepEqual(m.universes.idea, { kind: 'draft', name: 'New World', books: [], playground: ['Drafts/New World/'], supporting: [] });`
+
+The line gains only `, supporting: []`; nothing else in it moved. The business.test and scope.test hunks
+add tests only (sage-3713: no OK needed). The other old-test change in this row is survey.test:73
+(mos-1330 item 4, 28918824c). Doc only.

+`supporting`:
+- Every universe kind takes an optional `supporting` list: plain `['name','books','playground','supporting']`,

+- Each value is checked as a playground prefix is: a string ending in `/` whose body passes `folder()`.
+- The output carries `supporting` on every universe, `[]` when absent, the way a draft carries
+  `books: []`. classify then needs no `?? []`. The business writer writes the raw document
+  (organization.mjs:195), not this output, so no business file changes shape.
+- The prefix rules, across every entry (ruling after r11):
+  - A supporting prefix holding another supporting prefix, or one listed twice, refuses
+    `library-mapping-invalid`.
+  - A prefix equal to one of its own entry's book folders, or holding one, refuses `library-mapping-invalid`.
+  - A prefix inside or holding another entry's book folder refuses `library-supporting-other-universe`.
+  - Level comes from where the prefix sits, as for the playground: inside one of its own entry's books
+    is book level, and outside every book is universe level. A draft's prefixes are all universe level.
+- Between the two lists (my choice, Q2):
+  - A supporting prefix may equal a playground prefix of the same entry. That folder is writable.
+  - A playground prefix may hold a supporting prefix of the same entry. The inner folder is supporting
+    and the rest stays playground.
+  - A supporting prefix that holds a playground prefix refuses `library-mapping-invalid`. classify
+    checks supporting first, so that playground prefix could never match.
+  - A supporting prefix equal to, holding or inside a playground prefix of another entry refuses
+    `library-mapping-invalid`. Otherwise one path would have two universes.
+- The book loop at mapping.mjs:128-140 becomes a helper that both lists call with their own code and
+  label. The playground's messages and codes stay byte-equal, so no existing test text moves.
+
+`editor`:
+- The entry takes an optional `editor`. When present, it is an object with exactly the keys `name` and
+  `email` (via `only()`). Each value is a string that is non-empty after trim and has no control
+  character (`[\u0000-\u001f\u007f-\u009f]`), `<` or `>` (webby-0169 R1: git drops them from an ident
+  and commits under a different name, so C2-02 would never see a failure). Anything else refuses
+  `library-mapping-invalid`.
+- The output carries `editor: { name, email }` only when present, as `user` and `vaultPrefix` do. A save
+  with no `editor` refusing is C2-02's job.
+
+## 2. Scope (scope.mjs)
+
+- `classify` gets a supporting loop before the playground loop (design 1.2). It returns `place(...)`
+  with `{ scope: 'supporting', universe, book }`. The book is the book folder holding the prefix, or
+  null at universe level and in a draft. The type and folder come from the first folder under the
+  prefix, as for the playground.
+- The `.md` check stays first, so a `.canvas` or `.base` under a supporting prefix stays unmapped.
+- The comment above `classify` names the three prefix scopes and the order.
+
+## 3. supportingPath (new supporting.mjs)
+
+`supportingPath(mapping, universe, path, tree)` returns `path` or throws
+`LibraryError('library-write-story-path', ...)`. It is pure and reads no git.
+
+- `tree` is the array `listTree` returns (reader.mjs:26, `{ mode, type, oid, size, path }`), so the
+  C2-02 broker passes its listing as it is (Q3). A non-array `tree` throws a TypeError, because that is
+  a caller bug, not a path class.
+- The checks run in this order, each with its own message naming the class:
+  1. The path must be a string of at most 1,024 UTF-8 bytes (`Buffer.byteLength`).
+  2. It must have no control character, using the same control class as `editor` (not `<` or `>`).
+  3. It must have no backslash.
+  4. It must not be absolute (a leading `/`).
+  5. It must have no empty, `.` or `..` segment. That also catches `//` and a trailing `/`.
+  6. `classify(mapping, path)` must give scope `supporting` and that same `universe`. This one check
+     covers an unknown universe, an unmapped path, a `.canvas`, `.base` or attachment, a canon or
+     story path, a playground path that isn't also supporting, and another universe's prefix. The scope
+     rule then has one source, and M1 below hits both.
+  7. Every proper prefix of the path (`a`, `a/b`, ...) and the path itself must not be in `tree` with
+     mode `120000` (symlink) or `160000` (gitlink).
+  8. No prefix of the path, and not the path itself, may equal a tree path or a tree directory
+     (derived from the entries' paths) after `normalize('NFC').toLowerCase()` on both sides, unless
+     it equals that tree path exactly. NFC as well as case, because APFS treats NFC and NFD forms of
+     a name as one file (webby-0169 N1).
+     Directories are checked too, because the folders under a supporting prefix are hers to name. A
+     path in a tree that holds both `a.md` and `A.md` refuses, which matches R7.
+- The refusal messages quote the path with JSON, except for the control-character class, whose message
+  leaves the path out.
+- The delete rule ("A delete also needs the path to exist at the tip as a 100644 blob", M12) isn't in
+  the brief's supportingPath list. It stays with C2-02's delete (Q4).
+  The C2-02 brief doesn't name it (only design :308), so BUILD.md carries it to C2-02 under Handoffs
+  (webby-0169 Q4).
+- index.mjs exports `supportingPath`.
+
+## 4. README (packages/library/README.md)
+
+- Mapping: `supporting` and its rules, the cross-list rules, and `editor`.
+- Refusals: a `library-supporting-other-universe` row, and the new cases in the
+  `library-mapping-invalid` row.
+- Scope: supporting first, then playground, then canon.
+- A new section, "Agent write paths", for supportingPath and its classes.
+
+## 5. Callers of classify outside files owned (Q1 for Sage)
+
+- survey.mjs:65 builds `{ canon: 0, playground: 0, unmapped: 0 }` and increments
+  `scopes[classify(...).scope]`. A supporting file adds `supporting: NaN`, and formatSurvey (:92) never
+  prints it. I propose a departure: add `supporting: 0` and print it, so the line becomes
+  `scopes canon 5, playground 1, supporting 0, unmapped 3; indexed 6`. That re-pins survey.test:73 and
+  adds a count test. Without it, the survey reports garbage once she marks a folder. The departure
+  covers two files, packages/library/src/survey.mjs and packages/library/tests/survey.test.mjs.
+- No change in the rest, each for a reason:
+  - reader.mjs:183 skips only unmapped, so supporting files are indexed like playground files.
+  - R5 (:207) flags only canon to playground, as design 1.3 R5 says. A canon link to a supporting file
+    raises nothing.
+  - render.mjs:23 gives supporting a null badge. The supporting badge belongs to C2-10b (design :1415).
+  - mirror.mjs:246 refuses only unmapped. Reading supporting files by scope is C2-05c's.
+  - No bus or webui source filters on scope (git grep at 94c33a43c).
+- M9 already protects the whole `projects` key from agent edits (library-projects-protected.test). No
+  test is added there.
+
+## 6. Tests
+
+- mapping.test:
+  - T1: `supporting` at book level, at universe level, in a hybrid and in a draft. The output carries
+    it, with `[]` when absent. The draft `deepEqual` at :48 gains `supporting: []`.
+  - T2: one test per prefix rule.
+    - These refuse `library-mapping-invalid`: no trailing `/`, a bad folder, one holding another, one
+      listed twice, one equal to its own book, one holding its own book, one holding a playground
+      prefix, and one overlapping another entry's playground.
+    - These refuse `library-supporting-other-universe`: one inside another universe's book, and one
+      holding another universe's book.
+    - An equal same-entry playground passes.
+  - T3: `editor` passes, and absent passes. It refuses `library-mapping-invalid` for a non-object, an
+    array, an extra key, a missing key, an empty or blank value, a non-string, and a control character,
+    `<` or `>` in either value.
+- scope.test, T4:
+  - Supporting at book level, universe level and in a draft each give their universe and book.
+  - A folder in both lists is `supporting`, and a playground-only folder is `playground`.
+  - A supporting `.canvas` or `.base` is unmapped.
+- supporting.test (new):
+  - T5 passes at book level, universe level, in a draft, in a both-lists folder, and at exactly 1,024 bytes.
+  - T6 has one refusal per class against a fixture tree with a symlink, a gitlink and a case variant.
+    The classes are:
+    - unmapped, `.canvas`, `.base`, an attachment, canon, playground-only, another universe's
+      supporting prefix, and an unknown universe;
+    - absolute, `..`, `.`, `//`, a trailing `/`, a backslash, a C0 control and DEL;
+    - a symlink folder, a gitlink folder, and a symlink at the path itself;
+    - a case-variant file, a case-variant folder, and an NFD-form variant of an NFC tree name;
+    - 1,025 bytes made with a multi-byte character, so bytes and characters differ.
+  - Each asserts the code `library-write-story-path`.
+- business.test: T7 adds one assertion that `validateBusinessDocument` refuses
+  `library-supporting-other-universe`.
+- survey.test (only if Q1 is approved): T8 counts one supporting file, and :73 is re-pinned.
+
+## 7. Mutants (exact strings go in BUILD.md)
+
+| Mutant | Change | Killed by |
+|---|---|---|
+| M1 | classify checks playground before supporting (the brief's mutant) | T4 both-lists, T5 both-lists |
+| M2 | the other-universe fail for supporting is dropped | T2 |
+| M3 | the symlink and gitlink check is dropped | T6 |
+| M4 | the case check is dropped | T6 |
+| M4b | check 8 drops `normalize('NFC')` | T6 NFD variant |
+| M5 | the byte length uses `path.length` | T6 1,025 bytes |
+| M6 | the `editor` control-character check is dropped | T3 |
+| M6b | the `editor` `<` and `>` check is dropped | T3 |
+| M7 | supportingPath skips the universe match | T6 other universe |
+| M8 | the supporting-holds-playground check is dropped | T2 |
+
+## 8. Gate
+
+- Webby approves the manifest.
+- The library and business suites and every scripts/test-*.sh are green on Sage's gate.
+- Timeouts (mos-1275): each package `timeout -k 10 1800`, each script `timeout -k 10 300`, each single
+  file and mutant `timeout -k 10 600`. These come from my row 256 gate at 10:34Z.
+- Before in-review, grep packages/*/tests for 64-hex pins on the changed files and for the changed
+  message text, then drift-check BASE..refactor.
+
+## 9. Questions
+
+- Q1 (Sage): approve the survey.mjs and survey.test.mjs departure in section 5?
+- Q2 (Webby): the cross-list rules in section 1?
+- Q3 (Webby): `tree` as the `listTree` array?
+- Q4 (Webby): the delete's 100644 check stays with C2-02?
+- Q5 (Webby): `editor` refuses only blank values and control characters, as the brief says. `<` and `>`
+  would break a git ident. I'd leave them to C2-02's commit step unless you want them refused here.
+
+## 10. Draft 2 (webby-0169)
+
+- R1 folded: `editor` refuses `<` and `>` too, with T3 cases and mutant M6b.
+- Q2 accepted. BUILD.md records the tradeoff: refusing a supporting prefix that holds a playground
+  prefix goes past the brief, but it is the fail-closed reading and uses an existing code. The cost
+  is that she can't nest a playground under a supporting folder, though she can nest the other way.
+- Q3 accepted. Q4: carried to C2-02 under Handoffs in BUILD.md, and Sage was asked to add it to C2-02's brief.
+- N1 folded into check 8 (NFC and case), with an NFD case in T6 and mutant M4b.
+- N2: the survey.test:73 pin gains only `supporting`, and the count test is the only addition
+  (mos-1330, its own commit).
+- N3: before the build, re-grep tests outside packages/library for a `deepEqual` of the mapping output
+  on the build base.

-Builder: Launchpad until 2026-10-23 19:09Z. Then Mos moved coding to Codex seats (mos-1500, Q245) and
-the row went to Beakley on beakley/row217.
-
-## State at handoff
-
-All code in this commit is UNTESTED. No node, no test and no mutant has run on it. No test file is written.
-`packages/harness/src/runner.mjs` is not started.
-
-Done, untested:
-- `packages/library/src/limits.mjs` (new, pure): `REPLY_LIMITS`, `resolveReplyLimits(read)` gives
-  `{requireCitation, citationsPerReply, fallback, unreadable}`, `checkReplyLimits(value)` gives a clone or null.
-  An unreadable business file forces `requireCitation` true. A key falls back to its default when
-  `replyLimits` is not an object or the key holds an invalid value.
-- `packages/library/src/guard.mjs` (new): `GUARD_CODES` in design 5.2's table order, `FIXED_TEXTS`,
-  `WEB_CITE_DEFINITIONS`, `REASON_MAX` (300), `GuardError`, `parseReply`, `checkReply`, `libraryReader`,
-  `lastCommits`, `guardReply`.
-- `packages/library/src/index.mjs`: exports for both.
-- `packages/business/src/business.mjs`: `replyLimits` is a known top key. The validated output doesn't carry it.
-- `packages/business/src/organization.mjs`: the M11 fence `replyLimitsFence(old, document, actor)` compares
-  against `old.human`, refuses the tester and any `<definition>.<instance>` of `old.roles`, and is called for
-  both `document` and `written`. `setReplyLimits` and `readRaw` are exported.
-- `packages/bus/src/broker.mjs`: the guard call, the page store, the check event, `library.limits.set`,
-  `library.status` gains `replyLimits`, `role.claim` gains `library`, `thread.messages` gains `check` and `last`.
-- `packages/bus/src/server.mjs`, `client.mjs`: `BusError.reason` (sage-3599).
-- `packages/bus/src/runtime.mjs`: guard deps and the `library.limits.set` dispatch.
-- `packages/cli/src/limits.mjs`: `limits replies --file LIMITS`.
-
-Left:
-- `packages/harness/src/runner.mjs`: the C2-07 runner work (see "Runner plan" below).
-- `packages/cli/README.md`: a line for `limits replies`.
-- Every test in the brief and the rulings below, then the mutants.
-- The rebases onto rows 283, 216 and 285, with the drift checks below.
-- This file's gate results and the manifest.
-
-## Rulings in force
-
-sage-3595:
-1. Supporting scope: a stub classify test now. Before in-review, rebase onto row 283's landing
-   (honker/row283-build bd2c1c4ea when ruled) and add two real-fixture tests: a supporting cite with
-   `as: "canon"` refuses `playground-cited-as-canon`, and the stored check result names `supporting`.
-2. runtime.mjs is approved for the guard wiring and the one `library.limits.set` branch. List its hunks here,
-   name it in the manifest, and drift-check it after the 216 and 285 rebases.
-3. The check result is an `action.allowed` event with `action: "message.checked"`. The events kind CHECK at
-   `packages/bus/src/migrations/3b.sql:9` has no `message.checked`, so a new kind would be a schema step.
-   The event and the message INSERT share one transaction: a mutant that splits them must fail.
-4. readLibrary at the cited commit stands in for the C2-05a index. On the 216 rebase, compare 216's index
-   set with readLibrary's for the fixture and record the result here.
-5. The retry is for a library business only. Tests: a JSON body between 32,768 characters and 64 KiB gets
-   the retry; outside a library business nothing changes.
-6. Old `role.claim` pins stay as they are.
-7. `render.mjs:6` and `render.test.mjs:58` belong to row 225. Leave them.
-8. `thread.messages` rows that carry `check` get `last` per path cite: the file's last commit at the served
-   tip, one git call per distinct path per read. Test with a fixture file committed after the cite.
-
-sage-3599: `BusError` gets an optional `reason`. Only the citation guard's refusals set it. The envelope
-carries `reason` only when it is set. It is the guard's own text, never a quote, file text, url or a path
-other than the cited one, at most 300 characters. Tests: a guard refusal reaches the runner with code and
-reason; a refusal without a reason has an envelope byte-identical to today's, checked against an existing
-pin; a mutant that drops the client.mjs pass-through fails.
-
-sage-3602: store `file` per path cite from the same git log call as the trailer. Test with a cited commit
-that didn't touch the file, so `file` differs from the cited commit, and `last` equals `file`.
-
-## The check-result contract with row 225 (launchpad-0118, launchpad-0120, morgana-0200, sage-3596)
-
-- Stored on the `message.checked` event: `{citations: [...]}` in body order.
-- A path cite: `{scope, agent, file}`. `scope` is the classify scope. `agent` is the cite's file's last
-  commit's `Mosaic-Agent` trailer at the cited commit, or null. `file` is that commit's 40-hex id, or null.
-- A url cite: `{scope: "web", agent: null}`.
-- On `thread.messages`, each path cite gains `last`: the file's last commit at the served tip (40-hex or null).
-  The Console compares `last` with `file`.
-- Rows without `check` are unchanged. No `changed` boolean. The webui passes rows through unchanged.
-
-## Hunks outside the brief's file list
-
-- `packages/bus/src/runtime.mjs`: imports `setReplyLimits`; the library deps gain `guard`, `replyLimits`
-  (organizationWriter `readRaw`, or `{readable: false}` with no organization), `last` and `GuardError`;
-  the organization dispatch gains `library.limits.set`.
-- `packages/bus/src/server.mjs`: a `refusal(e, other)` helper above serve's doc comment builds every
-  BusError envelope and adds `reason` only when set. The synchronous request path accepts a Promise result
-  (the guard is async), with a 120 s timeout, and releases `own` when it settles.
-- `packages/bus/src/client.mjs`: `new BusError(r.error, reason)` with `reason` a string cut at 300.
-
-## Decisions and their tradeoffs
-
-- The guard runs async outside the SQL transaction, then re-enters request() through `#guardPass`, so
-  message.send's insert and the check event stay one synchronous transaction.
-- The guard runs before message.send's own checks, so a guard code can come before an authority code.
-- The check event id is derived from the message id (a UUID-shaped sha256), so `thread.messages` finds it
-  through the unique index on `events.id`.
-- With no organization configured, `replyLimits` reads as unreadable, so it fails closed.
-- With more than one library project, the guard uses the first in the business file's order.
-- A library business without guard deps refuses guarded sends with `project-not-configured`.
-- The page store is per cap: 20 pages of 200 KB, kept only in a library business, dropped at session
-  delete or disconnect and at run end.
-- The CLI `replies` verb reads the revision itself from `limits`.
-- Guard reasons never carry a url or a quote (sage-3599).
-
-## Runner plan (not built)
-
-`role.claim`'s reply is discarded at `runner.mjs:462`; keep it and read `library === true`. In a library
-business, at the reply site (`runner.mjs:582-587`):
-- Fixed texts `(the session gave no answer)` and `(the turn failed)`; the reason stays in the run log.
-  A fixed text goes with no note, and `unslop.sent()` is not called, so the note waits.
-- A body that parses as a JSON object with a string `text` gets `unslop.note()` appended to `text`, is
-  serialized again and is never clipped. A plain body keeps `clip(body) + unslop.note()`.
-- On a refusal whose code is in `GUARD_CODES`, or `request-too-large` from the client, or the broker's
-  `invalid-request` from `string(a.body, 32768)` for a body over 32,768 characters (ruling 5; the runner
-  can tell it by the body length it sent), run one new turn in the same
-  session naming the code and `err.reason`, or the 64 KiB limit. Bracket it with usage like other turns.
-- After the retry: a table code sends `(no answer passed the citation check)`, too large sends
-  `(the answer was too long to send)`. One retry per answer, whatever the cause.
-- `runTurn`'s output buffer holds up to 4 * BODY_MAX characters, so a reply over 64 KiB can reach the send.
-- Outside a library business nothing changes.
-
-## Mutants planned
-
-- The M11 writer check removed.
-- `document.human` compared instead of `old.human`.
-- The check event split from the insert transaction.
-- The client.mjs reason pass-through dropped.

+## Choices where the design table is silent or differs
+
+These are departures or gaps. Each is built as stated, so Sage can rule before Phase B. A ruling that changes one of them is a small edit.
+
+1. **Paging arguments (gap a).** The table has no offset. `find` and `search` take an optional `offset` (a position in the filtered list, default 0). A reply carries `next`: the position of the next item, or `null`.
+2. **`library_get` has no universe (gap b).** Built with a required `universe`. Without it the reply could not be isolated. A missing file and a file the universe cannot see both return `null`, so a caller cannot tell them apart. `get` also takes an optional `from` line.
+3. **`get` over the cap (gap c).** Lines page by `from` with `next`. `links_out` and `links_in` come back whole on every page. If the frontmatter and links alone exceed the cap, the call is refused with `query-item-too-large`. A hub note with many backlinks may be refused. This needs a ruling: link paging, or accept the refusal.
+4. **`manuscript` without a chapter (gap d).** Refused with `query-chapter-required`. The design names no list form. A chapter name that matches two visible files is refused with `query-chapter-ambiguous`.
+5. **`search` excerpt (gap e).** The excerpt is the whole line, not a truncation. A line that alone exceeds the cap is refused. Truncating it would cut an item.
+6. **`exclude` form (gap f).** `checkMapping` accepts only a folder path for `exclude` (`folder()`), so an exclusion is a path prefix. There is no type or source form to build. Confirm.
+7. **Pin constraints.** `pin` does not hide any file. It is reported by `universeInfo` only. Confirm.
+8. **Playground through `get`.** `scope` applies to lists. `get` by an explicit path returns a playground file of the caller's own universe. Confirm.
+9. **Links.** A link into a file the universe cannot see is dropped from `links_out` and `links_in`, in line with N1. Links from a visible file that point into another universe are kept in the index (the reader keeps them under R6), and the query layer drops them for universes that cannot see them.
+10. **`find` matching.** Case-insensitive substring over the front matter `name` and the file name. An empty `query` matches every file in scope.
+11. **Cache key.** `repo`, `commit` and a sha256 of the canonical mapping. Keying by commit alone would return the wrong scopes after a mapping change. The cache holds eight entries, least recently used out. Failed reads are not kept.
+12. **`universeInfo`.** Reads only the checked mapping and the served commit. It builds no index.
+13. **Reply commit.** Every reply carries the index commit, which is the served commit passed in.
+
+## Provisional refusal codes (pending Sage approval)
+
+The brief says new refusal codes need Sage's approval first. These are provisional and must not be treated as settled:
+
+- `query-argument-invalid`
+- `query-universe-unknown`
+- `query-chapter-required`
+- `query-chapter-ambiguous`
+- `query-item-too-large`
+
+Reused, existing codes: `library-mapping-invalid`, plus the reader's `library-git`, `library-commit` through `indexFor`.
+
+## Grep results (grep only, not a test run)
+
+- Test references to the changed paths: `packages/library/tests/*.mjs` import `../src/index.mjs` and `../src/mapping.mjs`. `packages/bus/tests/library.test.mjs` and `library-sync.test.mjs` import the library index as a namespace. Neither enumerates its exports, so the two new export lines break no assertion.
+- `packages/cli/tests/stack-copy.test.mjs:52` checks that `packages/library/src/index.mjs` exists, and it still does.
+- 64-hex pins: none in `packages/library/tests`, none on `index.mjs`, `query.mjs` or `index-build.mjs`.
+- `scripts/test-*.sh`: no reference to the new modules.
+
+## Flag for Sage
+
+- `packages/library/tests/helpers.mjs` `repo()` builds its fixtures under `tmpdir()`, which is `/tmp`. The launcher rules forbid that. The new tests do not use it; they use `tests/query-fixture.mjs`, which builds under `/mnt/storage/scratch/tmp`. The existing helper should be fixed in a separate row, not here.
+
+## Phase B commands (not run)
+
+Run only after Sage sends "slot clear". Set the scratch TMPDIR first, per the launcher rule.
+
+```
+cd /mnt/storage/src/mosaic-stack/.claude/worktrees/agent-aa3cc98787bc5152c/packages/library
+export TMPDIR=/mnt/storage/scratch/tmp
+node --test tests/query.test.mjs tests/index-build.test.mjs
+node --test tests/*.test.mjs
+```
+
+Also run `packages/bus/tests/library.test.mjs` and `library-sync.test.mjs`, since they import the index.
+
+## Status
+
+Not yet verified. Nothing has been tested and nothing is committed. The working tree holds the Phase A changes. AGENTS.md invariant 8 allows a commit only after the applicable suites are green, so the commit waits for Phase B. The dispatch asked for a local commit in Phase A; Sage to confirm that the commit waits for Phase B.
+
+## Round 2 (2026-10-22, sage-2708, sage-2716): rulings applied, rebased onto aca16404c
+
+Added after the text above; nothing above is edited. "Nothing is committed", "Provisional refusal codes",
+`query-chapter-required` and the tmpdir flag above were true when written and are superseded here.
+
+- Branch `researcher/row216-r2`, one local commit on origin/refactor `aca16404c`. Row 268 (C2-01c) is in
+  that base. Row 253 has not landed; the work rebases onto 253's tip before any gate. Not pushed, not run.
+- Rulings: `agents/sage/work/queue-216/RULINGS.md` at da9555ca2, rulings 1-13 and the tmpdir flag.
+- Drift check, d37210288..aca16404c against my paths: the library files that changed are `mapping.mjs`,
+  `scope.mjs`, `README.md` and the mapping and scope tests. None is a file I add or edit. `query.mjs` reads
+  the checked mapping through them, so the whole library package runs in phase B.
+
+### What changed from phase A
+
+| Ruling | Change in `query.mjs` | Test |
+|---|---|---|
+| 3 `get` over the cap | `links_out` and `links_in` page together with `links_from`; every reply carries `links_next`, `next` and the front matter. A page with lines left carries at least one line. Links take at most half the cap while lines remain. `query-item-too-large` is left for front matter alone or one line alone (or one link alone) | hub note with 900 backlinks pages and adds up; front matter alone and a line alone refused; bad `links_from` |
+| 4 `manuscript` no chapter | `chapter` optional: the first visible chapter in path order. Every reply carries `next_chapter`. `query-chapter-required` removed. Ambiguity still refuses | first chapter and `next_chapter`; ambiguous name refused |
+| 5 `search` long line | hit comes back `{path, line, excerpt: null, excerpt_too_long: true, scope}`, other hits still return | marked hit and unmarked hits in one reply |
+| 6 `exclude` | path-prefix reading only. The test names `EXCLUSION` and `EXCLUDED_PATHS` in `query-fixture.mjs`, so C2-15 (row 267) swaps two constants | exclusion hides from the hybrid and not from the source |
+| 8 hybrid `get` | unchanged code; test added | hybrid gets a source's playground file as `null`; the source gets it with `scope: "playground"` |
+| PRD 1.14 (row 268) | `universeInfo` reports `kind` from the mapping (`draft` included) | four tests below |
+
+PRD 1.14 tests, one each: a lookup naming a `book` leaves `book: null` files out (find and search);
+`library_manuscript` never reads a `book: null` file; a draft universe has no canon, so its lookups return
+files only with `scope: "playground"`; `library_universe` on a draft returns kind, name and prefixes.
+The levels fixture is `WITH_LEVELS` in `query.test.mjs`: harbor gets `Notes/Harbor/` as a universe-level
+playground prefix, and `idea` is a draft over `Drafts/New World/`.
+
+`query-fixture.mjs` builds under `tmpdir()`, as `helpers.mjs` does (ruling "tmpdir flag"). The earlier
+flag about `helpers.mjs` building under `/tmp` is closed by that ruling: the gate sets `TMPDIR`.
+
+Refusal codes now: `query-argument-invalid`, `query-universe-unknown`, `query-chapter-ambiguous`,
+`query-item-too-large`. All four approved in the rulings.
+
+### Grep results (grep only, not a test run)
+
+- `git grep` over `packages/*/tests/*` and `scripts/*` for `query.mjs` and `index-build`: no hit outside
+  `packages/library/tests/query*.test.mjs` and `index-build.test.mjs`.
+- 64-hex pins naming a library path: none. Positive control: the same pathspec finds the sha256 lines in
+  `packages/cli/tests/case1-hostcheck.test.mjs` and the `packages/library/src/index.mjs` existence check at
+  `packages/cli/tests/stack-copy.test.mjs:52`.
+- Tests that read `packages/library/src` as a directory: `packages/cli/tests/stack-release-fixture.mjs:309`
+  copies `packages/library/src` whole into a release fixture. It carries no file list, so two new files break
+  no assertion. `stack-release.test.mjs` is not in the gate unless Sage wants it.
+- Tests that import the library index as a namespace: `packages/bus/tests/library.test.mjs` and
+  `library-sync.test.mjs`. Neither enumerates exports, so the two export lines add no break. Both run
+  whole in phase B.
+
+### Run limits (fixed before any run)
+
+Every node file runs as its own `setsid -w timeout -k 10 LIMIT node --test FILE`; nothing runs unbounded.
+
+- Node test files: LIMIT 900 s. The library test files have no recorded time. 900 s is above the longest
+  recorded whole-package run I know of (cli, 591 s, row 281 BUILD.md "Runs" step 3), so it holds the 3x rule
+  for any single file. The first run records each file's time, and a file past 300 s gets a limit re-derived
+  from it before the next run. `query.test.mjs` builds a 900-file repo and a 3,000-file index rebuild is in
+  `index-build.test.mjs`; both are the files most likely to need it.
+- No shell script is in this row's gate, so no script limit applies.
+
+Any timeout goes to Sage, then Mos, unplaced (mos-1275).
+
+### Phase B (not run; Sage's CLEAR first, then a rebase onto 253's tip)
+
+```
+export TMPDIR=/mnt/storage/scratch/tmp
+cd <worktree>/packages/library
+for f in tests/*.test.mjs; do setsid -w timeout -k 10 900 node --test "$f"; done
+cd ../bus
+for f in tests/library.test.mjs tests/library-sync.test.mjs; do setsid -w timeout -k 10 900 node --test "$f"; done
+cd ../cli
+setsid -w timeout -k 10 900 node --test tests/stack-copy.test.mjs
+```
+
+Mutants I propose (my list, not read off the brief; each is meant to be killed by the named test, and none
+has been thrown; the kill claims are unverified until CLEAR):
+
+- M-a: `sees()` returns true for a file of another universe: killed by "find is bound to its universe".
+- M-b: the playground filter dropped: killed by "playground appears only when asked for".
+- M-c: the hybrid reads a source's playground: killed by "a hybrid gets a source playground file as null".
+- M-d: `links_next` always null: killed by the hub paging test.
+- M-e: the book filter lets `book: null` through: killed by the PRD 1.14 book test.
+
+### Status
+
+Built, not run. `node --check` has not been run on this round's files (no node before the CLEAR); the
+phase A pass above covered the earlier text only. The commit is local and waits for no gate under Sage's
+sage-2716 instruction, which allows git and docs work only; push and claim wait for Sage's go.
+
+## Round 3: rebase onto 45dca69f6, drift check, hash-pin grep (2026-10-23T18:53:43Z, sage-3576)
+
+Appended; nothing above is edited. Git only; nothing run, nothing pushed. Branch researcher/row216-r4 holds the
+one row 216 commit on 45dca69f6 (origin/refactor, 10-23). Earlier base: 48e450ce8 (row 253).
+
+- Rebase: clean. `git range-diff 48e450ce8..038089e5f 45dca69f6..researcher/row216-r4` shows the commit as `=`.
+- Landed in 48e450ce8..45dca69f6: 1175 files. Path overlap with this row's 7 paths: none. packages/library: no
+  landed file. packages/harness/src/tools.mjs (imported by query-fixture.mjs or the tests): not landed.
+- Hash-pin grep (the item 216 owed): 64-hex in packages/library: none. Positive control: 364 files in
+  packages/*/tests and scripts match 64-hex. Tests and scripts that name library files by path:
+  bus/tests/library.test.mjs and library-sync.test.mjs and bus/src/runtime.mjs import library/src/index.mjs;
+  business/src/business.mjs and its test import library/src/mapping.mjs (unchanged by this row);
+  cli/tests/stack-copy.test.mjs, stack-release-fixture.mjs:310 and stack-release.test.mjs:1991 copy
+  packages/library/src as a tree; scripts/stack-copy.sh:37 copies it; scripts/mosaic:41 runs survey.mjs. None pins
+  a hash of index.mjs, index-build.mjs or query.mjs.
+- bus/src/runtime.mjs landed changes after 48e450ce8 and uses libraryModule by named members (ensureMirror, SLOT,
+  readLibraryFile, libraryStatus, sync, LibraryError, SYNC_INTERVAL_MS) only; the landed diff touches none of them,
+  and this row's two new index.mjs exports (query and index build) are not iterated by any caller.
+- Gate additions for phase B: run bus library.test.mjs and library-sync.test.mjs whole (they import index.mjs), and
+  the cli stack-copy and stack-release tests that copy packages/library/src.
+
+## Round 4: phase B on 4e5d28ab2, two test fixes for r5 (2026-10-23T20:20:51Z, sage-3702, mos-1528)
+
+Appended; nothing above is edited.
+
+Phase B receipts on 4e5d28ab2 (researcher-r216-kit/out-b1): library whole 114 pass, 2 fail; bus library.test and
+library-sync.test 12 pass; cli 266 pass. The 3,000-file rebuild took 3807 ms (the test, with fixture setup, 4070 ms;
+`t.diagnostic` in index-build.test.mjs). No row 216 mutant was required or thrown in that round.
+
+The 2 library reds are test faults, not product faults. Both are placed as first-run reds in files this row adds
+(mos-1272); Mos ruled both fixes in mos-1528 and Sage relayed it in sage-3712.
+
+- R4: `packages/library/tests/index-build.test.mjs`, test "a different repo path, mapping or commit gets its own
+  index". Old: `writeFileSync(join(repo, 'Book One/Places/New.md'), …)` with no `Book One/Places` folder in FILES, so
+  the write failed with ENOENT. New: one `mkdirSync(join(repo, 'Book One/Places'), { recursive: true })` before the
+  write (import line gains `mkdirSync`). No assertion changes.
+- R5: `packages/library/tests/query.test.mjs`, test "a hybrid sees its sources canon, minus exclusions, and no
+  playground". The assertion sorts the actual paths and compared them to an unsorted literal, so the literal had
+  the wrong order (Characters before Chapters; Second World Characters before Chapters). New: only the expected
+  literal is reordered into sorted order. The `.sort()` on the actual side stays, and the assertion still checks
+  order. The set of seven paths is unchanged.
+- Product code: no edit.
+
+Reruns owed after the r5 commit (run on Sage's CLEAR, after the 283 gate): index-build.test.mjs whole,
+query.test.mjs whole, library whole, and the mutants those two files kill (M-a to M-e above). Results are appended
+below as a new entry.
+
+Run limit note: stack-release.test.mjs ran 644 s in the cli run. A per-file limit of 3 x 644 = 1932 s covers it.
+Sage's gates run cli as one whole-package `node --test` under 2100 s.
+
+Carry notes from Filbert's static check (doc only, no change in r5): N1 and N2 stay recorded as he gave them. The
+`After` list in this file still names row 268; row 268 landed at c27207f6e.

+# Row 220: C2-10a, no raw session view (M7) and no raw Discord engine (M8)
+
+Phase A. No test, suite or mutant has been run. Sage opens the slot.
+
+- Owner: researcher seat (Haiku 5.5 subagent), dispatched by Sage under lead decision 129.
+- Reviewer: Filbert.
+- Branch: `researcher/row220`, from `origin/refactor` at d37210288.
+- Brief: `docs/plans/2026-10-20_case2-rows.md`, C2-10a (line 495) and "Rules every row keeps".
+- Design: `agents/gosalyn/work/case2/DESIGN.md` on `origin/gosalyn/case2-design`, sections 5.1 (M7, M8), 7.6, 8 (row list).
+
+## Status
+
+| Item | State |
+|---|---|
+| M7 reader side (`conversation-not-listed`) | Built. Tests written, not run. |
+| M7 production wiring (the caller that passes `isCreative`) | Not built. Outside the file list, and it needs a ruling (question 1). |
+| M8 `discord check` and `discord run` refusals | Not built. `packages/discord/src/cli.mjs` is untouched. Blocked on question 1 and question 2. |
+
+Phase A is therefore partial. The row cannot pass its acceptance until Sage rules on the questions below.
+
+## Files
+
+- `packages/conversation/src/reader.mjs`: exports `NOT_LISTED`; `createReader` takes `isCreative` (default `() => false`); `catalogue()`, `open()` and `next()` hide a root for which it returns truthy.
+- `packages/conversation/tests/reader.test.mjs`: three new tests, inserted before the "unknown conversations" test.
+- `agents/researcher/work/queue-220/BUILD.md`: this file.
+
+Nothing else is changed. `node_modules` in the worktree is a symlink to the canonical checkout and is ignored by git.
+
+## Brief and design items mapped to tests
+
+| Item | Test |
+|---|---|
+| M7: a creative session file under the root isn't listed | "M7: a creative seat's session is not listed and won't open by id; an assistant seat still lists" |
+| M7: and won't open by id (`conversation-not-listed`) | same test; second check of the open refusal in "M7: a creative session already open refuses its next page once the root is hidden" |
+| M7: an assistant session still lists | same test (the `sage` seat is listed and opens with its text) |
+| M7: an already-issued cursor stops once the root is hidden (my addition; the design's "won't open" implies it) | "M7: a creative session already open refuses its next page once the root is hidden" |
+| M7: refused rows and the unsupported placeholder of a creative root are hidden too (my addition; the design hides "creative sessions", and a refused row or placeholder names one) | "M7: a creative root's refused files and its unsupported placeholder are hidden as well" |
+| Default behavior without `isCreative` is unchanged | the existing reader suite; the default predicate returns false |
+| M8: `discord check` / `discord run` refuse `discord-engine-not-allowed` on a library business, and a `mosaic-bus` binding with `tools` | none (not built, question 1) |
+| M8: a pi binding on a business without a library still checks clean | none (not built, question 1) |
+
+Every test's fixture text is `CREATIVE-MARKER` or a made-up assistant line. The M7 tests assert the marker is absent from the catalogue and refusal output.
+
+## Choices made in phase A
+
+- `isCreative(root)` is the reader's only input. The reader reads no business file. A truthy answer hides, so a doubtful answer fails closed. The predicate must depend on `root.seat` and `root.project` only, because a cursor is checked against the root object from an earlier listing.
+- Hidden check placed after the cursor's actor/purpose/conversation/branch checks in `next()`, and before the source is read.
+- `open()` checks hidden after the id resolves, so a creative id gets `conversation-not-listed`, and an unknown id still gets `unknown-conversation`.
+- `conversation-not-listed` is `reconcile: false`. The design names no reconcile flag. `unknown-conversation` uses true. Question 3.
+- The default predicate is `() => false`. Until a caller passes one, M7 does nothing. This is the open risk, and question 1 covers it.
+
+## Grep over `packages/*/tests` and `scripts/test-*.sh` (static, phase A)
+
+Changed path `packages/conversation/src/reader.mjs`:
+- `packages/conversation/tests/reader.test.mjs:14` imports `rootsFromSpecs, createReader, conversationId, cwdInProject, UNSUPPORTED_HARNESS`. It is the file under change.
+- `packages/control-board/tests/serve.test.mjs:26` imports `UNSUPPORTED_HARNESS`. That export is unchanged.
+- `packages/library/tests/sync.test.mjs:15` imports `packages/library/src/reader.mjs`, a different file. Not a hit.
+- `scripts/test-*.sh`: no reference to the conversation reader.
+- 64-hex pins naming this path: none. `packages/bus/tests/grant-migration.test.mjs:24` has a 64-hex value, but it is a DDL digest, not a pin on this path. That file matched only the word "reader" in a test title.
+
+Changed path `packages/conversation/tests/reader.test.mjs`:
+- No other test or script names this file. It runs through `packages/conversation`'s `node --test tests/`.
+- No 64-hex value in the file.
+
+Changed path `agents/researcher/work/queue-220/BUILD.md`: no pin.
+
+`node --check` passed on both changed `.mjs` files.
+
+## Phase B plan (not run)
+
+The reader test uses `os.tmpdir()`. Set `TMPDIR` to a scratch dir first, per the rule against `/tmp`.
+
+```
+export TMPDIR="$(mktemp -d /mnt/storage/scratch/tmp/r220XXXXXX)"
+cd packages/conversation && node --test tests/reader.test.mjs
+cd packages/conversation && node --test tests/
+cd packages/discord && node --test tests/
+cd packages/control-board && node --test tests/serve.test.mjs
+```
+
+The first command is the touched file whole. The second and third are the conversation and discord suites whole, as the brief asks. The control-board serve test is not in the brief. It consumes `reader.mjs`, so I recommend it. Sage can drop it.
+
+## Questions for Sage
+
+1. **Business link (blocks M8 and the M7 wiring).** Neither rule can be built from this row's file list, because the inputs don't exist in the code:
+   - A reader root carries `seat` (the spec's `agent`) and `project` (the repo directory name). It has no business id. Roots come from control-board scan specs (`packages/control-board/src/scan.mjs`, `discoverRepoAgents`) and seat registrations. Neither carries a definition.
+   - A Discord binding has `seat` and no business key (`packages/discord/src/binding.mjs`, `TOP_KEYS`).
+   - Creative status lives only in the business file: `roles.<instance>.definition` in `CREATIVE_DEFINITIONS` (`packages/business/src/vocabulary.mjs:176`). A library project is `projects.<id>.kind === "library"` (`packages/business/src/business.mjs:243`).
+   - Creative thread sessions are stored at `<dataRoot>/threads/<business>/<thread>/session` (`packages/seat/src/session.mjs:59-64`), outside the `.pi/state` roots the board scans. M7 may therefore reach only creative seats that have a `.pi/state` session root. Please confirm.
+   - The design does not define the mapping from a seat to a business.
+
+   Recommendation: add a required `business` key to the binding, validated against `businesses/<id>.json`. The board builds `isCreative` from `loadBusiness(id)`: a root is creative when its seat is a `roles` key whose definition is in `CREATIVE_DEFINITIONS`, and the business has a library project. This needs file scope for `packages/discord/src/binding.mjs` and `cli.mjs` (M8), and `packages/control-board/src/serve.mjs` (M7 wiring). None of those is on this row's list. I need that scope amendment and the mapping ruling before I build M8 or the wiring.
+
+2. **M8 refusal code for a `mosaic-bus` binding with `tools`.** The design names `discord-engine-not-allowed` for the engine case and no code for the tools case. A new code goes to you first. My proposal is to reuse `discord-engine-not-allowed` with a message that names the tools key.
+
+3. **`reconcile` on `conversation-not-listed`.** I chose `false`. Confirm or change.
+
+4. **HTTP status for `conversation-not-listed`.** `REFUSAL_STATUS` in `packages/control-board/src/serve.mjs` has no entry, so the route returns 422. My proposal is 404, next to `unknown-conversation`. This needs that file on the scope list too.
+
+Phase A stops here. On your "slot clear" I will run the phase B commands above. I will not build M8 or the wiring until question 1 is answered.

+
+Phase A only. No node, npm, `node --check` or test run has happened in this round, and nothing is
+committed. Phase B (the suites) waits for the coordinator's "slot clear".
+
+- Owner: researcher seat (Haiku 5.5 subagent), dispatched by Sage under lead decision 129.
+- Reviewer: Filbert.
+- Branch: `researcher/row220-r2`, from `origin/refactor` at da9555ca2. The r1 cherry-pick 3fa833715 is
+  staged with `-n`.
+- Rulings: `agents/sage/work/queue-220/RULINGS.md` on origin/refactor (da9555ca2). Import-by-path is
+  followed: no export line in `packages/business/src/index.mjs`, and `packages/discord/src/binding.mjs`
+  is untouched.
+
+## Coordinator rulings, applied
+
+Round 1 answers (earlier packet): applied as before. Absent `businesses/` gives empty sets only on
+ENOENT; other failures throw. stack-copy test joins phase B. Webui fixtures pass `businessDir` (renamed `configDirectory` in round 2b below). Discord
+refusals exit 2.
+
+Round 2 rulings (coordinator message, this round):
+
+1. **Dangling symlink at `businesses/` refuses.** `loadSeatSets` calls `lstatSync(join(dir, "businesses"))`
+   first. Only an lstat ENOENT (nothing at the path) returns empty sets. If something is there and
+   `readdirSync` fails for any reason, including ENOENT through a dangling link, it throws `BusinessError`.
+   Test added: "a businesses symlink to a missing target throws; no empty set". The absent-directory test is kept.
+2. **Sets are read once per public reader call.** `createReader` takes `creativeCheck`, a factory. Each
+   `catalogue()`, `open()` and `next()` calls it once, then applies the returned predicate to every root.
+   A load failure refuses `conversation-business-unreadable` for the whole call. `serve.mjs` exports
+   `creativeCheck(dir = configDir())`, the factory, and `createServer` passes `creativeCheck(businessDir)`.
+   Test added: "one catalogue calls the creative check once, however many roots it lists". It counts factory
+   calls: 1 after `catalogue()`, 2 after one `open()`.
+3. **Phase B adds three test files:** `packages/webui/tests/tester-browser.test.mjs`,
+   `tester-cli.test.mjs` and `proof-cli.test.mjs`, run whole (they reach `fixture.mjs` through
+   `tester-fixture.mjs`). Phase B is 36 files: 33 plus these 3.
+4. **Scope additions approved** (coordinator round 2 ruling 4): `packages/control-board/tests/discord.test.mjs`
+   line 123 and the five webui test files (`fixture.mjs`, `history-fixture.mjs`, `relaunch.test.mjs`,
+   `return-flow.test.mjs`, `discord.test.mjs`). They stop tests reading the real config directory.
+5. **TMPDIR** for phase B is set by the coordinator under `/mnt/storage/scratch/tmp`. No code change.
+
+## Discord exit code
+
+Refusals from the library-seat check exit 2, the code the Discord CLI already uses for configuration and
+binding refusals.

+
+## Choices (for Filbert to check)
+
+1. **Absent versus unreadable `businesses/`.** Only nothing at the path reads as empty (lstat ENOENT). A
+   dangling symlink, a file, or an unreadable directory throws. Coordinator ruling 1.
+2. **Sets are read once per public call.** `creativeCheck()` runs once in each of `catalogue()`, `open()` and
+   `next()`. The returned predicate answers every root in that call. A catalogue with zero roots still
+   loads the sets once, so an unreadable business file refuses even an empty list. Coordinator ruling 2.
+3. **Behavior change, kept on coordinator ruling (round 2 follow-up): an unknown id or cursor loads the sets
+   first.** In `open()`, the check runs after `checkCaller` and before `resolveConversation`. In `next()`, it
+   runs at the start of the try. So with an unreadable business file, a known id and an unknown id both give
+   503 `conversation-business-unreadable`, where round 1 gave 404 `unknown-conversation` for the unknown id.
+   Checking the id first would give 503 for a hidden creative id and 404 for an unknown one, which reveals
+   whether the hidden id exists. Loading first answers every id the same way (fail closed). This reverses
+   round 1 choice 3. Test: `creative-hidden.test.mjs` "with an unreadable business file, a known and an unknown id both refuse with 503".
+4. **Discord refusals use the `code: message` form and exit 2.** Exit 3 is for brake refusals (STOP or a held
+   binding). A seat's engine or library membership is not a brake. The business CLI is not used as precedent.
+5. **The thread-store wall exists in part already.** `rootsFromSpecs` (`reader.mjs` line 44) drops any
+   sessions directory that is not `<project>/.pi/state/<seat>/sessions`. The M7 check is the second wall, for
+   roots built another way. The test checks both.
+
+## Static checks (read-only; no node)
+
+- **COPY_PATHS** (`scripts/stack-copy.sh` 29 to 41): `packages/business/src`, `packages/conversation/src`,
+  `packages/discord/src` and `packages/library/src` are present. `packages/control-board/src` is not. COPY_PATHS
+  is not changed.
+- **Stale names.** `grep -rn -E "isCreative|creativeRootPredicate" packages scripts` finds nothing after this round's edits.
+- **Board starts without `businessDir`.** Webui: all five direct starts pass it. Control board:
+  - `serve.test.mjs` has seven single-line starts without it (lines 402, 445, 464, 483, 509, 528, 907) and four
+    multi-line starts without it (114, 149, 229, 258). None of those tests reaches a conversation route.
+    Every conversation route call in the file (lines 1027 to 1171) follows a start that passes `businessDir`
+    (1006, 1075, 1124). Checked by line order.
+  - `creative-hidden.test.mjs` builds `creativeCheck(f.dir)` on its own scratch directory. No default is used.
+  - `discord.test.mjs` passes `businessDir` (line 123).
+- **Consumers of the two fixtures** (exact import strings, `from './fixture.mjs'`, `from './history-fixture.mjs'`):
+  - Direct `fixture.mjs` importers, 31 test files: board-held, browser-edge, browser, bus-browser, bus,
+    chat-browser, chat, discord, docs-browser, editor-browser, editor, instances-browser, limits-browser,
+    limits-route, messages, preview, proof, relaunch, return-flow, routes-browser, send-browser, send, serve,
+    settings-form, shell, sso-browser, sso, tester-listener, usage-browser, usage, views.
+  - `history-fixture.mjs` importers, 2 test files: conversation, history-return-flow.
+  - Total fixture consumers: 33. Plus `tester-browser`, `tester-cli` and `proof-cli` (through
+    `tester-fixture.mjs`, ruling 3): 36 files in phase B.
+
+## Phase B commands (after "slot clear" only)
+
+TMPDIR is set by the coordinator under `/mnt/storage/scratch/tmp`. The commands below assume it. The new
+tests call `tmpdir()`, so an unset TMPDIR would put them under `/tmp`, which bwrap hides.
+
+```sh

+```
+
+The webui line is 36 files, run whole. `history-fixture.mjs` and `tester-fixture.mjs` run through their
+consumers. No test has been run. The expectations above come from reading the code.
+
+## Open items
+
+a. Phase B checks the dangling-symlink test on this platform (lstat then readdir ENOENT must throw).
+b. Phase B checks the spy count (1 after catalogue, 2 after one open). A failure here means a public call
+   reads the factory more than once.
+c. Choice 3 is settled by the coordinator: keep 503 for unknown ids too. Phase B checks the new known-and-unknown test.
+d. The browser-based webui tests need a browser in this environment. A failure there would be environmental.
+   Phase B will show which.
+e. Nothing here has been executed. Phase B checks every expectation, including the unreadable-file test
+   (EACCES must throw), the root skip (uid 0 skips), and the webui consumers.
+
+## Resolved
+
+- Dangling symlink at `businesses/` (round 1 open item a, and round 1 question 1): refuses, ruling 1.
+- Tester and proof CLI tests (round 1 question 2): join phase B, ruling 3.
+- Per-root reads (round 1 open item b): replaced by one read per public call, ruling 2.
+
+## Rebase onto aca16404c, run limits, index export (2026-10-22, sage-2708)
+
+Added after the text above; nothing above is edited. "Nothing is committed" above was true when written.
+
+- Commit `6f656abac` on `researcher/row220-r2`, one commit, rebased from da9555ca2 onto origin/refactor
+  `aca16404c`. Row 253 has not landed; this rebases again onto 253's tip before any gate.
+- Drift check, da9555ca2..aca16404c against my 18 paths: one overlap, `packages/discord/src/cli.mjs`
+  (the processing-control imports, rows 264 and neighbours). The conflict was the import block only. I
+  kept both sides: the two landed `processing-control` imports and my `loadSeatSets` import. No landed hunk
+  is reverted. `checkLibraryEngine` and its call in `prepare()` merged without a marker.
+- Board starts: no test added since da9555ca2 starts the control board or reads a conversation route
+  without `businessDir`. `packages/webui/tests/shell.test.mjs` fakes the board and does not start it.
+- Two edits since the r2 text: (1) a missing space in `reader.mjs` `next()` (`held =typeof`) fixed;
+  (2) `packages/business/src/index.mjs` gets `export { loadSeatSets } from "./library-seats.mjs";`. The text
+  above says "no export line". RULINGS.md Q1 says the helper is "exported from the package index" and the
+  scope amendment lists "its export line", so the file wins and the export is added. The two callers still
+  import by path, so nothing needs the export today. Filbert: drop the line if you read the ruling otherwise.
+  The export adds no test; `node --check` has not been run on it (no node before the CLEAR).
+
+### Run limits (fixed before any run)
+
+Every node file runs as its own `setsid -w timeout -k 10 LIMIT node --test FILE`; nothing runs unbounded.
+
+- Node test files: LIMIT 900 s. I found no recorded per-file time for the conversation, discord, business,
+  control-board or webui files. 900 s is above the longest recorded whole-package run I know of (cli, 591 s,
+  row 281 BUILD.md "Runs" step 3), so it holds the 3x rule for any single file. The first run records each
+  file's time; if a file passes 300 s, the limit is re-derived from it before the next run.
+- Shell scripts: `timeout -k 10 LIMIT bash scripts/test-X.sh`, LIMIT = 3x the longest recorded run plus
+  120 s, taken from Megavolt's row 281 table (`agents/megavolt/work/queue-281/BUILD.md`, from Gander's
+  `agents/gander/work/queue-278/SHELL-LIMITS.json`). A script with no limit does not run.
+
+| Script | LIMIT | Script | LIMIT |
+|---|---|---|---|
+| test-auth | 126 s | test-land-work | 158 s |
+| test-conductor | 145 s | test-queue | 191 s |
+| test-config | 130 s | test-release | 157 s |
+| test-discord | 147 s | test-task | 231 s |
+| test-extension-package | 130 s | test-foundation | 240 s |
+
+Any timeout goes to Sage, then Mos, unplaced (mos-1275).
+
+## Round 2b: Filbert's early look and sage-2719 (2026-10-22T14:46Z)
+
+Added after the text above; nothing above is edited. Where earlier text says `businessDir`, the parameter is
+now `configDirectory` (below). Second commit on `researcher/row220-r2`, on top of ea6dc9eff. Not pushed, not
+run; `node --check` has not been run on any of these files (no node before the CLEAR).
+
+Rulings applied (sage-2719): Q1 keep the index export. C1, C2 and the fixture scope are changes.
+
+### Fixture scope: the parameter is a config directory
+
+`createServer` took `businessDir`, but `creativeCheck(dir)` reads `<dir>/businesses`, so every fixture that
+passed `join(root, 'businesses')` made the reader look in `<root>/businesses/businesses`. That read nothing
+(ENOENT, empty sets): isolation from the real config held by accident. Now:
+
+- `createServer({ configDirectory = configDir() })` in `serve.mjs`. The parameter is not named `configDir`
+  because the import of that name is the default's source.
+- Every fixture passes the config directory it owns: `configDirectory: root` in the five webui files,
+  `f.root` in `control-board/tests/discord.test.mjs`, and `f.configDirectory` in `serve.test.mjs`.
+  `conversationFixture()` and `replyFixture()` both return `configDirectory: root`. The seven reply starts
+  that passed `f.businessDir` (undefined, falling back to the real `configDir()`) now pass a real value.
+- The dead `mkdirSync(join(root, 'businesses'))` lines in the five webui fixtures and in `serve.test.mjs`
+  are removed. So is the one in `discord/tests/helpers.mjs` `makeDeployment`, whose comment said "a missing
+  one refuses"; that was false (lstat ENOENT gives empty sets). The comment now says nothing there means no
+  library seat. Tests that need a `businesses/` directory create it: `writeJson` does, and the two
+  unreadable-file tests in `library-seat.test.mjs` call `mkdirSync` themselves.
+- Proof that the fixture's own business file is the one read: the new default-reader test (C2) hides `bean`
+  and shows `pm`, and nothing else in that fixture says which is which.
+
+### C1: M8 on `run`
+
+`library-seat.test.mjs` gains three `run` tests: a raw engine, a mosaic-bus binding with `tools`, and an
+unreadable business file. Each asserts exit 2 and the code in stderr, and that `s.d.journalDir` does not
+exist (`ensureJournal` comes after `prepare()` in `run`, so nothing was started). `run()` calls
+`initializeControl(dataRoot)` first, because `run` stops at `assertProcessing` before `prepare()`, as the
+STOP test in `binding.test.mjs:203` does. There is no `run` test for a clean seat: that would go on to the
+network.
+
+### C2: the default reader
+
+`creative-hidden.test.mjs`, "the board's default reader hides a creative seat's session from the listing and
+the detail route". It calls `startServer` with no `conversationReader`, `configDirectory: f.dir`, a `bean`
+session and a `pm` session on disk, and drives HTTP: the listing holds `pm` only; bean's detail is 404
+`conversation-not-listed`; pm's detail is 200; after a broken business file lands the listing is 503
+`conversation-business-unreadable`.
+
+### Mutants to throw (CLEAR only; none thrown; the kill claims are unverified)
+
+| Id | Mutation | Meant to be killed by |
+|---|---|---|
+| M7-w | delete `creativeCheck: creativeCheck(configDirectory),` in `createServer` (`serve.mjs`) | the default-reader test, first assertion (the listing shows `bean`) |
+| M7-c | `hiddenCheck()` in `reader.mjs` open() returns `() => false` | reader.test "hides the creative seat" and the `creative-hidden` 404 asserts |
+| M7-o | `creativeCheck` catch returns an empty set instead of throwing | the 503 asserts in `creative-hidden` |
+| M8-p | delete `checkLibraryEngine(...)` in `prepare()` | the three `check` refusals and the three `run` refusals; one mutant covers both verbs because they share `prepare()` |
+| M8-e | `loadSeatSets` returns empty sets on any lstat error | `library-seats` ENOENT-vs-file tests |
+
+### `refusalResponse` and `catalogue()`'s refusal (past "predicate wiring and REFUSAL_STATUS only")
+
+Why it is needed: the reader's `catalogue()` now returns a refusal when the business check throws (M7: no
+partial list), and `conversationResponse` had no way to turn a catalogue refusal into a status. `open` and
+`next` already built `{ status: REFUSAL_STATUS[code] ?? 422, body: { error, refusal: { code, reconcile } } }`
+inline; that expression moved, character for character, into `refusalResponse(out)` so the listing could
+use it too.
+
+No existing route's status or body changes:
+
+- `open` and `next` refusals: the same expression, now behind a function. `git diff aca16404c..HEAD --
+  packages/control-board/src/serve.mjs` shows the line as a move.
+- `/api/conversations` success: `{ status: 200, body: listing }` where `listing` is what the route returned
+  before. `catalogue()` returned `ok: true` on every path before this row, so the new branch is reached only
+  by the business refusal.
+- The "no parameters are accepted" 400 is untouched.
+
+Phase B runs `serve.test.mjs`, `discord.test.mjs` and the conversation route tests whole, so Filbert can
+check this statement against a green run.
+
+### Smaller changes from the early look
+
+- Spy test: one `next()` call adds a third `creativeCheck` count (`reader.test.mjs`). The catalogue assert
+  also checks `refusedRoots` is empty, in the same test and in the thread-store test in `creative-hidden`.
+- `library-seats.test.mjs` mode-000 test pins `BusinessError` and its message (`must be a regular,
+  non-symbolic-link file`, from `readJsonFile`'s open failure).
+- "passes the engine rule" now asserts exit 0 and `offline check passed`. The expectation is unverified: if
+  a mosaic-bus binding fails some other offline check, that is a first-run red to place (mos-1272).
+
+### Carried, not changed here
+
+- `conversation/src/controller.mjs:176` builds a reader with no `creativeCheck`. No `src` file imports it
+  today; a live wiring must pass the check. Raised for Sage.
+- `discord run` reads the business file once at start. `engine` and `tools` are FIXED_KEYS, so only a
+  business-file change while a connector runs goes unseen until the next start.
+- `creative-hidden` and `library-seats` use the repo `roles/` as the default `rolesDir`.
+
+### Gate additions
+
+Phase B list is unchanged: the same suites run whole, plus the files above are inside them. The drift check
+against `aca16404c..refactor`, including files these tests copy or read, repeats after the rebase onto 253.
+
+## Round 2c: refusalResponse statement corrected from the diff, controller.mjs follow-up (2026-10-22T14:55Z, sage-2729)
+
+Appended after Round 2b; nothing above is edited. This replaces Round 2b's refusalResponse statement, which I
+wrote from memory of the code. Source: `git diff aca16404c HEAD -- packages/control-board/src/serve.mjs` and
+`packages/conversation/src/reader.mjs`, read in full. No test has run.
+
+### What the diff shows in serve.mjs
+
+- `open` and `next` refusal: the object expression `{ status: REFUSAL_STATUS[out.refusal.code] ?? 422, body: {
+  error: out.refusal.message, refusal: { code, reconcile } } }` moved unchanged into `refusalResponse(out)`.
+  The two call sites reach it by `return refusalResponse(out)`. Status and body are identical for every code
+  that reached it before.
+- `REFUSAL_STATUS` gains two keys, `conversation-not-listed` (404) and `conversation-business-unreadable`
+  (503). Before, those codes did not exist, so no earlier response used them or changes. Every other key is
+  untouched.
+- `/api/conversations` with a query string: the 400 `no parameters are accepted` line is untouched.
+- `/api/conversations` success: before, `{ status: 200, body: reader.catalogue() }`; now the same object
+  when `listing.ok` (it is the same `listing`), so the 200 body is unchanged.
+- The one new response shape: `/api/conversations` can return a refusal (503 or the refusal's status) when
+  the business check throws. That is the M7 behaviour, not a change to an existing route's response.
+
+### What the diff shows in reader.mjs, past my Round 2b statement
+
+`catalogue()` is now wrapped in `try { ... } catch (err) { return refuse(err); }`. `refuse` returns a refusal
+object for a `Refusal` and rethrows anything else (`reader.mjs:352-355`). So a non-Refusal error still
+propagates as before. A `Refusal` escaping the loop body would now come back as `{ ok: false }` where it
+used to throw. The loop already catches `Refusal` from `listSessionFiles` and from `summarize`, so the only
+`Refusal` that newly reaches the wrapper is the hidden check's. I have not confirmed that `listRoots()`
+(`rootsFromSpecs`, `loadRegistrations`) never throws a `Refusal`; if it does, that call now returns a
+refusal. Filbert's round check should read `rootsFromSpecs` for `Refusal` throws.
+
+Round 2b said the old `catalogue()` "returned ok: true on every path". True for returns; it could throw.
+
+### Named follow-up for DEFERRED (Sage lands it with 220; it does not block 220)
+
+`packages/conversation/src/controller.mjs:176` builds a reader with no `creativeCheck`. No `src` file imports
+`controller.mjs` today, so no live path leaks. Whoever first wires `controller.mjs` live must pass
+`creativeCheck` (`creativeCheck(configDirectory)` from `control-board/src/serve.mjs`, or the reader's own
+equivalent) and add a test that a creative seat's sessions stay hidden through that path.
+
+## Round 2d: can listRoots() throw a Refusal into catalogue()? No (2026-10-22T14:53Z, sage-2730)
+
+Appended after Round 2c; closes the question Round 2c left open. Static read on 9a9f6dd54; nothing run.
+Filbert reached the same answer independently (filbert-220-r2c-static).
+
+`catalogue()` calls `listRoots()` inside the new `try`. In production that is `serve.mjs:261`,
+`roots: () => rootsFromSpecs(specs, loadRegistrations(seatsDir).registrations)`. The only `Refusal` class
+the reader catches is the one in `conversation/src/safe-fs.mjs:21`.
+
+- `rootsFromSpecs` (`conversation/src/reader.mjs:38-71`) calls `resolve`, `join`, `basename`, `Array.find`,
+  `toTime` and `samePath`, and constructs no `Refusal`.
+  - `toTime` (`conversation/src/pi.mjs:21-26`) returns a value or null and has no throw.
+  - `samePath` (`seat/src/seat.mjs:261-269`) wraps `realpathSync` in try/catch and returns false.
+- `loadRegistrations` (`control-board/src/scan.mjs:272-292`) catches `SeatError` and rethrows anything
+  else. It calls `readRegistration` (`seat/src/seat.mjs:200-216`), which throws `SeatError` only.
+- `grep -n "Refusal\|refuse(" packages/control-board/src/scan.mjs packages/seat/src/seat.mjs` finds
+  nothing, and neither file imports `safe-fs.mjs` (checked with `grep -n "^import"`). A `Refusal` cannot
+  originate in either.
+- Inside the loop, `listSessionFiles` is caught at `reader.mjs` (the `catch (err)` that rethrows
+  non-Refusals) and `summarize` turns an `openSessionFile` Refusal into a `denied` row.
+
+So the only `Refusal` that reaches the new catch is the hidden check's `conversation-business-unreadable`.
+Any other error still throws through `refuse()` (`reader.mjs:352-355`) exactly as before.
+
+Therefore `/api/conversations` has no status change for a path that existed before this row: the old
+throw paths are unreachable by a `Refusal`. The one new response is the business refusal, already pinned by
+the creative-hidden 503 assertion and the reader catalogue-refusal test. No extra test is added.
+
+The exception is an injected `roots` function that throws a `Refusal` itself; only a test could pass one,
+and none does.
+
+Time correction (2026-10-22T14:51:01Z): the heading times of Round 2c (14:55Z) and Round 2d (14:53Z) were written before I read the clock. The commits were made at 14:49:40Z (9a9f6dd54) and 14:50:52Z (176ac262e). The heading of Round 2b (14:46Z) is also an estimate; its commit e4a204836 was made before 14:47:53Z.
+
+## Round 4: rebase onto 45dca69f6, drift check (2026-10-23T18:53:43Z, sage-3576)
+
+Appended; nothing above is edited. Git only; nothing run, nothing pushed. Branch researcher/row220-r4 holds the
+five row 220 commits on 45dca69f6 (origin/refactor, 10-23). Earlier base: 48e450ce8 (row 253).
+
+- Rebase: clean. `git range-diff 48e450ce8..3ef6da90d 45dca69f6..researcher/row220-r4` shows all five commits as `=`,
+  so no patch changed.
+- Landed in 48e450ce8..45dca69f6: 1175 files (47 packages/bus, 32 webui, 29 cli, 10 plugins, 9 seat, 4 harness,
+  2 tasks, 7 scripts, BUILD-LOG.md, the rest agents/ and docs/).
+- Path overlap with this row's 19 paths: none.
+- Landed files in the packages these tests touch: webui (src/serve.mjs, src/cli.mjs, chat and bus files,
+  tests). Row 220's webui test changes are five fixtures that start the control-board server with
+  `configDirectory: root` and start the webui server with only `{ port, board }`; no landed webui file passes or reads
+  configDirectory. The landed webui tests are not in this row's change set, but a whole webui run covers them.
+  No landed file in control-board, conversation, discord or business.
+- Other users of the touched symbols (git grep on the r4 tree for createReader, rootsFromSpecs, creativeCheck,
+  configDirectory, businessDir, loadSeatSets, checkLibraryEngine, conversationReader outside this diff):
+  only conversation/src/controller.mjs:173-176 (the follow-up named in Round 2c) and the conversation README.
+- Hash pins: grep for 64-hex in packages/*/tests and scripts finds 364 files (positive control), and none pins a
+  row 220 source file by hash. Path-string hits for packages/discord/src/cli.mjs (copy-service.test.mjs,
+  scripts/test-discord.sh, discord-service.sh) are paths, not hashes.
+- Added to the gate list: `packages/discord/tests/helpers.mjs` is imported by 19 discord test files, and this row
+  removed its empty `businesses` mkdir. Phase B must run the discord package whole (and `scripts/test-discord.sh`),
+  not only library-seat.test.mjs.
+
+## Round 5: phase B on 2bb146b28, R1 and R2 fixes (mos-1528) (2026-10-23T20:21:39Z, sage-3712)
+
+Appended; nothing above is edited. The tree is 2bb146b28 plus the commits of branch researcher/row220-r5.
+
+Phase B receipts on 2bb146b28 (researcher-r220-kit out-b1, out-b2, out-b3, out-mut, out-npm):
+
+- discord 20 files, 200 pass; conversation 7 files, 187 pass; scripts/test-discord.sh rc=0, 82 passed.
+- control-board 7 files, 128 pass, 1 fail (serve.test.mjs, R2 below); business 26 files, 237 pass, 1 fail
+  (library-seats.test.mjs, R1 below).
+- webui: first run 409 pass, 1 fail (editor-provenance.test.mjs). Cause: the esbuild in the worktree's
+  node_modules resolved to the root copy (0.28.1) and not to packages/webui's own pin. Fix (R3, no repo change):
+  `cd packages/webui && npm ci --ignore-scripts --no-audit --no-fund` in the worktree, output in out-npm/npm-ci.txt;
+  esbuild is then 0.28.2. Rerun of all 65 webui files whole with MOSAIC_REQUIRE_EDITOR_BUILD=1: 65 of 65 rc=0, 410
+  pass, 0 fail.
+
+Fixes (both are test-only; src/ is unchanged from 2bb146b28; Mos ruled both in mos-1528):
+
+- R1, `packages/business/tests/library-seats.test.mjs`, test "M7/M8: a business file that can't be read throws; no
+  empty set". The fixture registers `rmSync(root)` as a `t.after` hook before the test registers its
+  `chmodSync(file, 0o600)` restore, so on the way out the restore found the file already removed and threw ENOENT.
+  Old: `t.after(() => chmodSync(file, 0o600));`. New: the same call inside try/catch that rethrows anything but
+  ENOENT. The assertion is unchanged.
+- R2 (option A, mos-1528), `packages/control-board/tests/serve.test.mjs:1073`, test "conversation routes (F16): a
+  foreign Host, a wrong port and a cross-origin Origin get 403 before the reader runs, with no CORS headers".
+  Failure: the same-origin request at the end reached the route, the spy's `catalogue` returned the number
+  `calls.push(...)` gives (1), and 220's `conversationResponse` reads `listing.ok`, so `refusalResponse(1)` threw on
+  `out.refusal.code` and the route answered 500. Old text:
+  `const spy = { catalogue: () => calls.push("catalogue"), open: () => calls.push("open"), next: () => calls.push("next") };`
+  New text: `catalogue` records the call, then returns `{ ok: true, conversations: [], refusedRoots: [] }`; `open` and
+  `next` are unchanged (the test never reaches them with a passing request). The assertions are unchanged: 200 for the
+  same-origin request and `calls` equal to `["catalogue"]`. serve.mjs stays as 220 has it.
+  Added test, same file before "every refusal code the reader can raise has an HTTP status": a reader whose
+  `catalogue()` returns `{ ok: false, refusal }` gets `conversation-business-unreadable`'s status (503) and the body
+  `{ error, refusal: { code, reconcile } }`. No such route test existed; the earlier claim that no route's status or
+  body changed was wrong for a reader that returns a bare value, which the old spy did.
+
+Mutants thrown on 2bb146b28 (out-mut; the base run for library-seats was red from R1, so a kill by that file is not
+shown there):
+
+| Mutant | Result |
+| --- | --- |
+| M7-w | killed by control-board creative-hidden ("the board's default reader hides a creative seat's session…") |
+| M7-c | killed: creative-hidden 4 fail, conversation reader 3 fail |
+| M7-o | killed: creative-hidden 4 fail |
+| M8-p | killed: discord library-seat 6 fail |
+| M8-e | SURVIVED: no test failed other than the base red in library-seats; handled in the next entry |
+
+Run limit: stack-release.test.mjs took 644 s. The per-file limit is 3 x 644 = 1932 s. Sage's gates run cli whole
+under 2100 s.
+
+Reruns owed after r5 (run on Sage's CLEAR): the touched files whole (library-seats, serve, and the M8-e test),
+control-board whole, business whole, and every 220 mutant, M8-e included. Results are appended as a new entry.
+
+## Round 5b: correction of the M8-e kill claim, and the test that kills it (2026-10-23T20:21:52Z, sage-3715)
+
+Appended; nothing above is edited. This is a correction to the "Mutants to throw" table in this file (the M8-e
+row, around line 270), which says M8-e, "`loadSeatSets` returns empty sets on any lstat error", is killed by the
+`library-seats` ENOENT-vs-file tests. That claim is wrong. M8-e changes the lstat catch to
+`return { librarySeats: new Set(), creativeSeats: new Set() };` for every error code, so only a test that makes lstat
+fail with a code other than ENOENT can kill it. The file-as-businesses test and the dangling-symlink test I named
+make lstat succeed or fail with ENOENT, never another code, so they pass under M8-e. Phase B on 2bb146b28 showed
+the mutant surviving (out-mut, M8-e: no failure besides the base red).
+
+Added in this commit, `packages/business/tests/library-seats.test.mjs`: "M7/M8: a config directory under a regular
+file throws (lstat fails with ENOTDIR); no empty set". The config path is a regular file, so
+`lstat(<file>/businesses)` fails with ENOTDIR; the test expects `BusinessError` matching "cannot list businesses".
+It is a new test in this row's own file, in its own commit, and droppable without touching R1 or R2.
+
+The rerun of M8-e on r5 (the test must fail under it) is owed and runs on CLEAR; the result is appended as a new
+entry.

+No launcher in this directory. The seat runs as a T3 thread (thread 6229eb89) and works in its own worktree. It has no

+never `refactor`, `main` or another seat's branch. Claude seats orchestrate and review (Q245). Registered by Sage on
+2026-10-23 so the queue can name the seat as row owner (store.mjs isSeatDir).

+# Brief: a GitHub consumer for row 297's protected token callback
+
+Sage, 2026-10-23, filed for Mos (mos-1525). Post-10-27.
+
+## Brief: a GitHub consumer for Broker.githubWithToken
+
+Row 297 builds the GitHub grant method and stops at the trusted host API
+`Broker.githubWithToken(business, agent, fn)` in `packages/bus/src/broker.mjs`.
+Nothing calls it yet: no git helper, mirror push or publication uses a GitHub
+token (violet BUILD.md, "Consumer gap for Sage's follow-up row").
+
+This row adds the first consumer.
+
+- It gets the token only through `githubWithToken`. It never reads the
+  protected generation files, and never routes GitHub through the generic
+  Gitea Credentials path, which has calendar-day dates and fork-specific
+  identity.
+- It honors the callback's cancellation signal. The signal aborts on revoke and

+- No socket verb returns a token, and no consumer output, log or run record

+Design comes first, with the consumer named (a git helper or mirror push), for

+# Brief: Case 1/2 host fixes for the 433 P1 rerun
+
+Sage, 2026-10-23, filed for Mos (mos-1532). Issue #1816, Vikunja 614. On the 10-27 path.
+
+## Brief: hostcheck item 5, bundle verify, case2-unit @, stack-copy cwd
+
+ops-01 found two defects in the 433 P1 Run A on VM 1013 (ops-0256). Row 240 (c515273db) introduced the first one.
+
+1. `scripts/case1-hostcheck.sh:117` compares `dpkg-statoverride --list /usr/bin/bwrap` to the literal
+   `root mosaic 0750 /usr/bin/bwrap`. dpkg 1.22.6 on Ubuntu 24.04 prints `750`, so item 5 FAILs on every
+   correctly built host. The apt hook and mosaic-hostcheck.service then close bwrap and write DRIFT. The fake
+   at `packages/cli/tests/case1-hostcheck.test.mjs:73` writes `0750`, so the suite missed it.
+2. `docs/guides/host-run-sheet.md:192` and `:209` run `git bundle verify` outside a repository, which fails on
+   a fresh host.
+
+The fix:
+- Item 5 accepts `750` and `0750` as the same mode for the statoverride line. Owner, group and path stay exact,
+  and every other mode still fails. The stat check at :118 is unchanged.
+- The run sheet verifies the bundle inside an empty bare scratch repo, as `scripts/stack-copy.sh:91-93` does.
+  A failure there prints a FAIL line and does not `exit` the interactive root shell (Morgana N1, sage-3743).
+
+Tests are append-only blocks in case1-hostcheck.test.mjs (mos-1272 pre-approved by Mos: 0 lines deleted, the :73
+fake unchanged). They cover: a `750` statoverride passes; `0750` still passes; `755`, `0755`, `7500`, `075`, `00750`, a tab
+or doubled space, and a wrong owner or group fail. Any other change to an existing test goes to Mos first.
+
+Scope add (mos-1534):
+3. F3: `scripts/case2-unit.sh:62` plain() rejects `@`, so the run sheet's required `--claude` path
+   (host-run-sheet.md:85-89, `@anthropic-ai`) refuses on every host (ops-0258, section 10). plain() accepts `@`.
+   The :61 comment doesn't list it as unsafe, so no requirement changes.
+4. F4: `scripts/stack-copy.sh` fails when run as mosaic from a cwd mosaic can't read: the sheet's `sudo -u mosaic`
+   lines and stack-upgrade.sh AS_USER at :154 and :293. It works from any cwd.
+Specs and test terms are in mos-1534. Mos pre-approved append-only test blocks in case2-unit.test.mjs under mos-1272.
+One new N carries F1 to F4 for the #433 rerun.
+
+Owner Gladstone. Reviewer Morgana. Gate: Morgana approves. Mutants are killed: dropping the `750` form, widening the
+match to any mode, rejecting `@` again in plain(), and the F4 cwd fix reverted. The touched test files run whole, and Sage's full landing gate runs every
+package suite and every `scripts/test-*.sh`. After landing, Mos sends ops-01 the new N for a full 433 P1 rerun.
+No hostcheck install on .53 or .54 until it lands.
+
+Scope add (mos-1536, ops-0260):
+5. F5: on a host that follows the run sheet, `mosaic-bus@<business>` exits 3 because nothing writes
+   `<dataRoot>/notify/<business>/notify.json` (bus cli.mjs:104-122 requires it, README :876-892), and case2-precheck
+   has no line for it, so it passed with the bus down. The run sheet gains a step that writes binding `null` as the
+   default, and case2-precheck gains a notify line with tests. Install does not write the file: the README wants an
+   explicit decision. A named binding for .53 is a later per-host choice that needs Mos's go. Spec in mos-1536.
+Gate adds a mutant: the precheck notify line removed or passing on a missing file. #1816 carries F1 to F5.
+
+Scope add (mos-1537, ops-0261):
+- F5 fixture: Mos OK under mos-1272 for the host(t) notify fixture in case2-unit.test.mjs and the world(t) one in
+  case2-install.test.mjs (a 0700 notify/acme dir and a null notify.json, with no assertion changed or deleted).
+  Conditions: the negative F5 tests build their host without the file; one append-only install test shows
+  notify.json bytes and mode are unchanged after install; the fixture lines are their own follow-up commit.
+- Section 9a creates both `notify/` and `notify/<business>` at 0700 (ops-0261 measured a 755 parent).
+6. F6: sheet :235 runs `stack-copy.sh check`, which requires `$HOME/.npm-global/bin/mosaic` (stack-copy.sh:160-173).
+   Nothing creates it: install runs only `copy` (:178), bootstrap has no .npm-global, and the sheet has no wrapper
+   step. The sheet gains a step after install: as mosaic from cwd `/`, create the bin dir, then run
+   `wrapper <sha> --create`, naming the Mos gate (stack-copy.sh:3). No requirement change. #1816 carries F1 to F6.
+
+
+## Brief: F7, the wrapper step's PATH and umask under sudo
+
+Row: F7 for the 433 P1 rerun (ops-0271, mos-1544). Docs only. Builder: a Codex thread. Reviewer: a separate Codex
+thread (mos-1542). It can land with any row and is not N+1.
+
+Defect, from ops-01 on 094124b4e: the run sheet's wrapper step (`docs/guides/host-run-sheet.md` :249-253) fails
+rc=127 `node: command not found`. `sudo -u mosaic -H /bin/sh` runs under sudo's `secure_path`, which drops
+`/opt/mosaic-stack/node-<v>/bin`, and `scripts/stack-copy.sh wrapper` reaches `scripts/instance.sh:78`, which calls
+bare `node`. The heredoc also sets no umask, so `$HOME/.npm-global/bin` came out 0775.
+
+Change, inside the `MOSAIC_WRAPPER` heredoc only:
+
+1. Before the `mkdir`, add `umask 077`, the same way the notify step does (:325).
+2. Before the `mkdir`, add `PATH=/opt/mosaic-stack/node-<v>/bin:/usr/sbin:/usr/bin:/sbin:/bin; export PATH`, using the
+   sheet's own PATH form (:69).
+3. Add one sentence above the block: the step runs under sudo's `secure_path`, so it sets its own PATH and umask.
+
+Nothing else in the sheet changes, and no script changes. ops-01 is testing this exact form on 1013 (mos-1544).
+
+Acceptance:
+
+- The heredoc has `umask 077` and the PATH line before `mkdir`, with `<v>` written the same as the sheet's other
+  node paths.
+- `git grep -n 'host-run-sheet' -- 'packages/*/tests/*' 'scripts/test-*.sh'` shows no test that reads the changed
+  lines (positive control: a grep for a path a test does read). If a test does read them, stop and report.
+- BUILD.md under `agents/<seat>/work/queue-<row>/` records the diff and the grep.
+
+F10, added to this row (ops-0274, mos-1548). Both are confirmed at 094124b4e.
+
+- After a first install, the sheet has no `stack-release.sh adopt <business> --instance <i> --units external` step,
+  so the first activate refuses `no-pointer` (`scripts/stack-release.sh:1297`, "no $POINTER; run adopt first"). Add
+  that step where the sheet first moves from install to activate or upgrade. It runs on Mos's go, and Jason or Mos runs
+  it (`stack-release.sh:14`).
+- The sheet doesn't say that the first `stack-upgrade.sh upgrade` after adopt needs `--no-rehearsal`. Adopt writes no
+  backup, so without the flag the upgrade refuses `no-backup` (`scripts/stack-upgrade.sh:324-325`), and with the flag
+  on a stack that has a backup it refuses `rehearsal-required`. Say so next to the upgrade command (sheet :210-223):
+  only the first upgrade after adopt takes `--no-rehearsal`.
+
+ops-01 is testing both on 1013 (mos-1548). F10 is also docs only. The grep in the acceptance list covers its lines too,
+and BUILD.md records them.
+
+## Brief: F8 and F9, the library persona import runs without the clone's node_modules
+
+Row: F8 and F9 for the 433 Run B rerun (ops-0273, mos-1546). Builder: a new Codex thread (mos-1542). Reviewer:
+Morgana (Claude), because the row touches the install path (mos-1542 rule 4). When it lands, ops-01 reruns Run B P1
+at that commit.
+
+F8, confirmed at N = 094124b4e: `scripts/case2-install.sh:185` runs
+`node "$REPO/scripts/case2-persona-import.mjs"` from the clone (`REPO`, :38). `case2-persona-import.mjs:32` imports
+`yaml`, and a fresh clone has no `node_modules`, so the import fails `ERR_MODULE_NOT_FOUND`. The copy just made at
+`$COPIES/$COMMIT` (:178) has `node_modules` (mos-1546). ops-01 reproduced `ERR_MODULE_NOT_FOUND` from a checkout
+with no `node_modules`.
+
+Fix F8 one of two ways, and say in BUILD.md which and why: run the importer from the copy
+(`$COPIES/$COMMIT/scripts/case2-persona-import.mjs`), or make node resolve its modules from the copy. The importer's
+relative import of `../packages/harness/src/bundle.mjs` must still resolve to the same commit's file. Whatever you
+pick has to work when the clone has no `node_modules` at all.
+
+F9: :186 keeps only `tail -n 1` of the importer's output. For an uncaught node error that line is the
+node banner (`Node.js v24.22.1` on 1013, mos-1546), so the refusal hides the cause. Make the refusal carry the error line, for example the first line
+matching `Error` or `ERR_`, falling back to the last line. Keep it to one line. Don't put a full stack trace in the
+refusal.
+
+Class check, same row: at N, `grep -n 'node "$REPO/' scripts/case2-install.sh scripts/case2-precheck.sh
+scripts/stack-copy.sh` finds only :185. Rerun that grep. Also list every clone-side `.mjs` those three scripts run
+that imports a package (a bare specifier, not `node:` or a relative path), and record the list in BUILD.md and the
+review request. Fix any other hit in this row only if it is the same defect, and say so.
+
+Test: add a new, append-only test block to `packages/cli/tests/case2-install.test.mjs`. It runs the library persona
+import with no `node_modules` beside the script, and must fail at N. It needs no mos-1272 OK (mos-1546). Add a second
+assertion that the F9 refusal carries the error line, not `Node.js v...`. In BUILD.md, explain why the existing
+case2-install tests missed this. ops-01 thinks the checkout's `node_modules` hid it; check that.
+
+Gate: Morgana approves the manifest. Every package suite (except queue) and every `scripts/test-*.sh` are green on
+Sage's gate, the new test fails on N, and a mutant that puts back `$REPO` at :185 is killed by the new test.

 Morgana, row 306 BUILD.md (#1813, landed 2d0318a44). A revoked run that also has a pending limit stop gets
 `#limitStop`'s `not-holder` on `message.receive` and `state`, because that check runs before `#agent`. It's

+## Row226 N1: the install id regex is narrower than ID_PATTERN
+
+Webby, row 226 round 1 (webby-0225, #1727, landed 661890e90). case2-install.sh:56 refuses a business id
+with `.` or `_`, which ID_PATTERN (vocabulary.mjs:199) and case2-precheck.sh:67 accept. Gosalyn confirmed
+it isn't deliberate (gosalyn-0208). It fails closed, so a real id with either character is refused, not
+mishandled. Bound to the next row that changes case2-install.sh: take the ID_PATTERN set, and add a test.

+## Row226 N2: a first-run validate refusal leaves personas and the slot dir
+
+Webby, row 226 round 1 (webby-0225). After a validate refusal on a first run, the staged personas and the
+empty token slot dir stay behind, and a re-run counts them as present. Bound to the same follow-up as N1:
+remove what this run created, as the business file path already does (install.sh:198/:202/:218).

+## Row226 N3: the run sheet doesn't pin the clone to the copy's sha
+
+Webby, row 226 round 1 (webby-0225). install.sh:217 validates with the checkout's scripts/mosaic, not the
+copy's, and host-run-sheet.md:237 never says the clone must be at `<sha>`. Bound to the same follow-up:
+a HEAD check in the install or one clause on the run sheet.
+
+## Row226 N4: --library-status refuses after a 5 s lock wait
+
+Webby, row 226 round 1 (webby-0225). If the bus holds the library lock for more than 5 s,
+`case2-precheck.sh --library-status` refuses with `ERROR library-sync-busy`. A re-run clears it. Recorded
+as a known operator step, no fix bound.
+
+## Row283 N1: SURVEY-RUN.md shows the scopes line without supporting
+
+Webby, row 283 round 1 (webby-0267, #1788, review note queue-283/REVIEW-manifest-b2a1f4092.md on
+webby/reviews c6ea27aab). docs/case2/SURVEY-RUN.md:96 documents the `--mapping` line as
+`scopes canon .., playground .., unmapped ..; indexed ..`, which predates the supporting scope 283 adds.
+Nothing reads the file (decision 137). Bound to the next docs commit that touches SURVEY-RUN.md: add the

 ## Scope
 
 `classify(mapping, path)` decides scope from the path alone. Only paths ending in lowercase `.md` are
-mapped. It checks prefixes first. A path under any entry's playground prefix is `playground`, with that
-entry as `universe` and the book folder holding the prefix as `book`, or `null` at universe level and
+mapped. It checks prefixes first, supporting before playground. A path under any entry's supporting
+prefix is `supporting`, and otherwise one under a playground prefix is `playground`. Either way that
+entry is `universe` and the book folder holding the prefix is `book`, or `null` at universe level and
 in a draft. Any other path under a book folder is `canon`. Everything else is `unmapped`. The type is
-the first folder after the playground prefix, or after the book: a `types` name, `manuscript`, or
-`null`.
+the first folder after the prefix, or after the book: a `types` name, `manuscript`, or `null`.
+
+## Agent write paths
+
+`supportingPath(mapping, universe, path, tree)` returns `path` when an agent may write it in that
+universe, else it refuses `library-write-story-path` (C2-01d, M12). `tree` is the array `listTree`
+returns for the commit the write lands on; anything else is a TypeError. It reads no git. The checks
+run in this order, so a path with two faults always names the same one:
+
+1. a string of at most 1,024 UTF-8 bytes;
+2. no control character (the `editor` class), and the message leaves the path out;
+3. no backslash;
+4. not absolute;
+5. no empty, `.` or `..` segment, which also refuses `//` and a trailing `/`;
+6. `classify` gives `supporting` in that same universe, which refuses unmapped, `.canvas`, `.base`
+   and attachment paths, canon, a playground-only folder and another universe's prefix;
+7. no folder on the way, and not the path itself, is a symlink (`120000`) or gitlink (`160000`) in
+   `tree`;
+8. no folder on the way, and not the path itself, matches a tree path or tree folder after
+   `normalize('NFC').toLowerCase()` unless it is that exact name. APFS folds case and Unicode form,
+   so her checkout would put the file somewhere else. A tree that already holds case twins refuses a
+   write to either (R7).
+
+A delete's further rule, that the path exists at the tip as a `100644` blob, belongs to the C2-02
+broker.
