row 251: BUILD.md slot results, part A reds at the predicted fractions only, fix 18/18, bus suite green 3 times and concurrently (sage-2154)

ssh-agent sets a key's death to whole seconds of CLOCK_BOOTTIME plus the lifetime and reaps on the
same whole seconds (OpenSSH 10.5p1 ssh-agent.c:1315, :1064, misc.c:1828), so -t 1 can end within
milliseconds of an add made late in a second. -t 2 keeps the key over 1 s; the sleep keeps its 1.5 s
margin past the 2 s ceiling. Both checks stay. host-run.mjs is unchanged: production adds with
timeout + 30. Evidence and the slot plan are in agents/darkwing/work/queue-251/BUILD.md.

+at 6afcee2a5) with three notes that don't block. Row 195's code landed as b65014647, and the notes are in

+"Row 195 follow-up" at 62ddc96cc, owner Darkwing, reviewer Duckworth, gate owner Sage (sage-1923).
+
+The branch is `darkwing/row245`, on 62ddc96cc. Its first commit is a cherry-pick of `darkwing/row195-n1`
+1e3c4767c, which was written on 37171f65b and never run. The script, test and TOOLS.md blobs are the same
+as in 1e3c4767c, and none of those paths changed between 37171f65b and 62ddc96cc.
+
+## What changes
+
+N1. F9 ran `$ROOT$NODE` as root (`case1-accept.sh:298` at 37171f65b) before F10 checked that `--node` is
+the pinned path. Duckworth offered two fixes: F9's parse through `AS_USER`, or F10's path check first. I
+took the path check, plus one more:
+- F9 now runs node only when `--node` equals `/opt/mosaic-stack/node-<--node-pin>/bin/node`.
+- Then `not_root_only` walks from that file up to `/`. Each entry must be the running user's (root's on the
+  host) with no group or other write, the rule `case2-unit.sh` `root_only` applied when it rendered the
+  units. A symlink fails it, because its mode is 777. The first entry that breaks the rule goes in the
+  evidence.
+
+I didn't run the parse through `AS_USER`. That would hand a check about a root file to the stack's user,
+and a process running as `mosaic` shares that node's uid. Whether it could change what node prints then
+turns on the host's ptrace setting, and the root-only check doesn't depend on that. Sage agreed in
+sage-1877. Rechecking ownership costs one loop and doesn't depend on
+how the host was installed.
+
+N2. The header (:9-15) and the `docs/TOOLS.md` entry now list what root runs: `systemctl show` and
+`is-enabled` (F1, P11), `curl` on the loopback healthz (F2), `sudo -l` (P1, P3), `sudo -u jarvis bwrap
+--version` and `hostcheck.sh --check` (P9), and node for F9 under the rule above.
+
+N3. F6 matched `--claude` by prefix, so `/opt/mosaic-stack/claude-<pin>/../claude-2.0.9/...` passed the
+path check. F6 now fails on any `..` segment, before it runs `--version`. F10 compares for equality, so
+it needed no change.
+
+Row 195's BUILD.md gets a correction entry for deviation 6. Row 195's DESIGN.md is unchanged. Its "either
+works" wording at `DESIGN.md:336-338` is superseded by gosalyn-0087 (root writes `dev.args` at W10), and
+it stays in place: an approved design isn't edited (sage-1877).
+
+## Tests
+
+`packages/cli/tests/case1-accept.test.mjs`:
+- The node stub touches `node-as-root` in the state directory when something runs it outside the fake
+  `sudo` (which sets HOME to the stack's home). `host()` sets the node file's directories and the scratch
+  root to 0755, so the umask can't fail F9.
+- "every check passing" also asserts that root ran the pinned node.
+- New: "F9 won't run --node as root off the pin path or with a writable directory above it". Another node
+  path fails F9 and F10, with no root run. A group-writable `bin/` and a symlinked node each fail F9
+  alone, with the bad path in the evidence and no root run.
+- The F6 test gains a `..` case: a path under `claude-<pin>/` by prefix that names 2.0.9's binary, which
+  prints the pin. F6 alone fails, with "has a .. segment".
+
+That makes 23 tests. All 23 pass on Sage's slot (results below).
+
+## Mutants
+
+The twelve from row 195 still apply, unchanged. These four are new, each one exact replacement:
+
+| # | Mutant | Expected killer |
+|---|---|---|
+| 13 | F9 runs any `--node` (the pin check becomes `true`) | F9 won't run (another node) |
+| 14 | F9 skips the ownership walk (`bad=""`) | F9 won't run (writable `bin/`, symlink) |
+| 15 | `not_root_only` checks only the file, not the directories above it | F9 won't run (writable `bin/`) |
+| 16 | F6 accepts a `..` segment | F6 stub, path and `..` |
+
+The brief's gate asks for a mutant for each of N1 and N3. Mutants 13-15 are N1's, and 16 is N3's.
+
+## Slot plan
+
+Same shape as row 195's steps, on this row's tip: the single test file, then the sixteen mutants, then
+the gate (the cli suite and every `scripts/test-*.sh`), each behind the busy checks and chained with
+`&&`. The scripts are in `/mnt/storage/scratch/darkwing-245-out/`.
+
+## Slot results (grant sage-1961, 2026-10-21)
+
+All three steps ran on 0590a29fc with node v26.8.1, launched from `/`. Both busy checks were CLEAR
+before each step.
+
+- Singles, 11:27:46-11:27:59Z: `case1-accept.test.mjs` passed 23, failed 0.
+- Mutants, 11:28:10-11:31:20Z: all 16 killed, each with exit 1. The runner restored the script, and
+  its sha256 875bb5b7 matches the committed blob. Rows 1-12 died as in row 195. 13, 14 and 15 died on
+  "F9 won't run --node as root off the pin path or with a writable directory above it". 16 died on
+  "F6 fails on a stub that prints nothing, on a path outside claude-<pin> and on a .. segment".
+- Gate, 11:31:20-11:42:51Z: the cli suite passed 664, failed 0, skipped 0. Every `scripts/test-*.sh`
+  exited 0: auth 15, conductor 17, config 31, discord 78, extension-package 18, foundation 44,
+  land-work 86, queue 28 (its node part 156/0), release 14, task 98. That's 429 selftests, none failed.

+# Row 251 build: T27 lists no identities right after `ssh-add -t 1` (Vikunja #453)
+
+Brief `docs/plans/2026-10-21_t27-ssh-add-lifetime.md` (rev 2931), Mos ruling mos-1185 item 2, assigned in
+sage-2075. Owner Darkwing, reviewer Dewey, gate owner Sage. Branch `darkwing/row251` from 3b0aef995,
+claimed in-progress at rev 2938.
+
+## Step 1: the failure names its cause (e5e4b2e5a)
+
+T27's two lists now carry a message that prints only when they fail. It gives the time from addKey's
+start to its resolve and to each `ssh-add -l` call, the hrtime at each with how far into its second it
+fell, `/proc/uptime` at each, and whether the agent process and its socket were still there. The checks
+themselves did not change. The commit holds nothing else.
+
+## Step 2: the cause
+
+ssh-agent counts a key's lifetime in whole seconds of CLOCK_BOOTTIME, at the add and at the reap. I read
+OpenSSH 10.5p1, the version on dragon-lin (`ssh -V`: OpenSSH_10.5p1), at tag V_10_5_P1 (ssh-agent.c
+sha256 873691c4, misc.c sha256 ee467f43):
+
+- `misc.c:1790-1798` and `:1828`: `monotime()` returns `ts.tv_sec` of `clock_gettime(CLOCK_BOOTTIME)`,
+  falling back to MONOTONIC. The fraction of the second is dropped.
+- `ssh-agent.c:1315`: the `-t` constraint sets `*deathp = monotime() + seconds`. Lines 1410 and 1598
+  do the same for the agent's default lifetime.
+- `ssh-agent.c:1064`: the reaper drops a key when `now >= id->death`, `now` being `monotime()` again.
+- `ssh-agent.c:2650`: the main loop runs `reaper()` after every poll, before it reads requests. A list
+  that arrives after the boundary sees the key gone.
+
+So a key added at second s plus a fraction f dies at s + N, and `-t N` keeps it N - f seconds, between
+N - 1 and N. With `-t 1`, an add late in a second leaves the key milliseconds to live. That matches
+Sage's probe in the brief: 8 of 80 `-t 1` adds missed, each one made at 0.9947-0.9973 of a monotonic
+second and finished at 0.998-0.0008, and none earlier in the second missed. It also matches proof 5's
+failure, where the first list ran 31.9 ms into the test and found no identities.
+
+Node's hrtime is CLOCK_MONOTONIC. BOOTTIME differs from it by the time the host spent suspended. On
+dragon-lin the difference read 0.000001 s at 19:09Z, so a monotonic second boundary is a BOOTTIME one
+here.
+
+`addKey` and the agent start are not the cause. `addKey` passes the lifetime through as `-t`
+(`host-run.mjs:90`), and the agent starts with no default lifetime (`:175`). Production adds the key
+with `timeout + 30` (`:180`), where losing up to a second makes no difference. The only caller that
+can't afford the lost fraction is T27, which asks for 1 s. The fix belongs in the test's lifetime choice,
+and `host-run.mjs` doesn't change.
+
+The slot confirms this against T27 itself (below), not just from the source.
+
+## Step 3: the fix (this commit)
+
+T27 adds the key with `-t 2`. The agent then keeps it more than 1 s and at most 2 s. The first list
+runs milliseconds after the add, so it has over a second of margin even under load. The sleep before
+the second list grows from 2.5 s to 3.5 s, which keeps the old 1.5 s margin past the new 2 s ceiling.
+Both checks stay: listed after the add, gone after the lifetime. A comment above the add says why the
+lifetime is 2.
+
+I considered `-t 3` with a 4.5 s sleep for a 2 s floor. One second of floor is far above anything the
+first list has needed (31.9 ms in proof 5), and the concurrent-suite run below tests it under load, so I
+took the smaller change.
+
+## Base
+
+The branch stays on 3b0aef995. By 19:15Z origin/refactor was at 6096b051b, after rows 66 and 243
+landed. `git diff 3b0aef995 6096b051b` touches neither `packages/bus/src/host-run.mjs` nor
+`packages/bus/tests/host-run.test.mjs`, so there's no rebase (sage-2084). Row 243 did change
+`packages/bus/tests/process.test.mjs`. My slot's bus suites run that file as it was at 3b0aef995, and the
+gate rerun on Sage's slot runs it as landed.
+
+## Prediction for part A on e5e4b2e5a (written before the slot)
+
+The hook starts `ssh-add -t 1` at the given fraction of a monotonic second. From the brief's probe, the
+agent stores the key about 3 ms later. The first list reaches the agent a few ms after addKey resolves:
+Node's exit event, the mark, and `ssh-add -l`'s own start. A red needs the add to land before the second
+boundary and the list to land after it.
+
+- 0.990: green. The add and the list both land before the boundary.
+- 0.993, 0.995, 0.996, 0.997: red expected. The add lands before the boundary, the list after. At 0.993
+  and 0.997 I'm less sure, because the list (at 0.993) or the add (at 0.997) can land right at the
+  boundary. A green at either is in line with the cause, and so is a red.
+- 0.998: green. The add lands after the boundary, so the key gets almost a full second.
+
+Every red should show "first list got" an answer with no SHA256 line. It should also show addKey
+resolving before a second boundary and the first list starting after it or within a few ms of it, with
+the agent alive and its socket present.
+
+Under sage-2084's rule, on e5e4b2e5a only a red at 0.990 or 0.998 counts toward the stop, and two such
+reds stop the run. On the fix commit any red counts, and two stop it. In parts B to D, the first red stops
+the run.
+
+## Slot plan
+
+All scripts are in `/mnt/storage/scratch/darkwing-251-out/`, launched from `/`, each behind the busy
+checks and chained with `&&`, TMPDIR under `/mnt/storage/scratch/tmp`.
+
+1. Confirmation. `align-hooks.mjs` is a load hook, outside the repo, that serves `host-run.mjs` with
+   `addKey` wrapped to start `ssh-add` at a chosen fraction of a monotonic second. T27 runs unchanged
+   under it, alone (`--test-name-pattern`). It runs at fractions 0.990, 0.993, 0.995, 0.996, 0.997 and
+   0.998, three times each:
+   - on e5e4b2e5a (step 1, `-t 1`). Expected: some first lists fail, and the step 1 message shows the
+     add's resolve and the list on either side of a second boundary, with the agent alive and the
+     socket present. These reds are the point of the run.
+   - on the fix commit (`-t 2`). Expected: all 18 pass.
+2. `host-run.test.mjs` whole, once, on the fix commit.
+3. The bus suite whole, three times in a row.
+4. The bus suite whole in two clean worktrees at the same commit, started together.
+
+## Slot results
+
+Sage's CLEAR came in sage-2154 at 20:58:55Z. `slot-251.sh` ran parts A and B from 20:59:22Z to 21:01:33Z,
+on node v26.8.1 and OpenSSH_10.5p1, with TMPDIR `/mnt/storage/scratch/tmp/r251`. At the start, BOOTTIME
+minus MONOTONIC read 0.000001 s, then 0.000000 s twice (dewey-0769 N1). So the hrtime fractions below
+put the agent's second boundary in the right place.
+
+### Part A: T27 alone under `align-hooks.mjs`, 3 runs per fraction
+
+The fraction is when the hook started `ssh-add`. The hook logged each start within 0.0001 of its target.
+
+| fraction | e5e4b2e5a (`-t 1`) | 68f2dfd4b (`-t 2`) |
+|---|---|---|
+| 0.990 | 3 pass | 3 pass |
+| 0.993 | 3 pass | 3 pass |
+| 0.995 | 3 red | 3 pass |
+| 0.996 | 3 red | 3 pass |
+| 0.997 | 3 pass | 3 pass |
+| 0.998 | 3 pass | 3 pass |
+
+e5e4b2e5a went red 6 times out of 18, every time at a fraction the prediction named, so none of them
+counted toward the stop. 68f2dfd4b passed all 18. The fix runs used 68f2dfd4b, whose test blob is the same
+as c19b4167e's (280132c7).
+
+Every red failed on the first list and got `"The agent has no identities.\n"`, with the agent alive and
+its socket present. The step 1 message gave these hrtime fractions. "addKey start" is the mark before the
+hook's wait, so its fraction is earlier than the ssh-add start.
+
+| run | addKey resolved | first list mark |
+|---|---|---|
+| 0.995 rep 1 | 0.9992 (+317.6 ms) | 0.9993 |
+| 0.995 rep 2 | 0.9991 (+846.5 ms) | 0.9991 |
+| 0.995 rep 3 | 0.9988 (+845.0 ms) | 0.9988 |
+| 0.996 rep 1 | 0.9999 (+839.8 ms) | 1.0000 |
+| 0.996 rep 2 | 0.0004 (+845.0 ms) | 0.0004 |
+| 0.996 rep 3 | 0.0002 (+835.9 ms) | 0.0002 |
+
+At 0.995 the add finished about 4 ms in, before the boundary, and the list mark came just before it. The
+`ssh-add -l` process then reached the agent after the boundary. At 0.996 the agent stored the key before
+the boundary, and addKey resolved just after it. In both cases the key's whole second ended between the
+add and the list, which is the cause step 2 gives. The two edge fractions came out green on the first
+build. At 0.993 the list still reached the agent before the boundary, and at 0.997 the add landed after
+it, so the key got almost a full second. The prediction allowed either result at those two.
+
+### Part B: `host-run.test.mjs` whole on 68f2dfd4b
+
+24 tests, 24 passed (21:01:18Z, 14.0 s).
+
+### The stop before C1, and the resume
+
+At 21:01:33Z the script stopped before C1, with exit 4 and no red. My own `busy.sh` matched two `sleep 60`
+processes, mine, in `darkwing-r251/packages/bus`. Part B left them. They come from T27 "the start sweep
+keeps a live bus dir and kills only a matching live process" (`host-run.test.mjs:528` and `:536`). Its
+`t.after` SIGKILLs the `/bin/sh -c 'sleep 60; :'` parent, but the `sleep` child lives on for up to 60 s.
+That code is outside this row's diff, so the row leaves it alone, and it's recorded below as a follow-up.
+Sage confirmed (sage-2159) that the right move is to resume only the scope that hadn't run.
+
+`slot-251-cd.sh` runs C and D as `slot-251.sh` has them, with the same two busy checks. Before each check,
+it waits up to 75 s for those orphans to exit: my uid, my trees, a command line of exactly `sleep 60`.
+It logs them as it waits. Any other process still trips the checks.
+
+### Parts C and D: the bus suite whole on 68f2dfd4b
+
+| run | start | tests | pass | fail | time |
+|---|---|---|---|---|---|
+| C1 | 21:02:48Z | 598 | 598 | 0 | 21.6 s |
+| C2 | 21:04:06Z | 598 | 598 | 0 | 21.4 s |
+| C3 | 21:05:26Z | 598 | 598 | 0 | 22.1 s |
+| D1, darkwing-r251 | 21:06:44Z | 598 | 598 | 0 | 24.2 s |
+| D2, darkwing-r251b, TMPDIR `r251-b` | 21:06:44Z | 598 | 598 | 0 | 24.2 s |
+
+The script waited 33 s before C2, 34 s before C3, 33 s before D and 32 s before the sweep. Each time it
+was waiting for that run's `sleep 60` orphans (two per suite, four after D), and nothing else. After the
+wait, the sweep of my trees, the out dir and TMPDIR found 0 processes left (21:08:04Z). Sage confirmed
+(sage-2159, sage-2160) that the short gitea-api and `node --check` runs they made during the slot weren't
+stops. None of my busy checks refused on any of them.
+
+These runs used the bus files as they were at 3b0aef995. Since then, origin/refactor (666173292, then
+7247d80c7 and c3d88840c with row 196) has changed `broker.mjs`, `runtime.mjs` and `server.mjs`, which T27's
+file imports, along with other bus files. None of those commits touch this row's two paths or
+`host-run.mjs`, and `git merge-tree` of c3d88840c with 68f2dfd4b is clean. The gate rerun in
+a clean worktree on Sage's slot runs T27 against them.
+
+### Follow-up, not in this row
+
+T27's start-sweep test leaves the `sleep 60` child of each planted shell running for up to 60 s after
+the test. Killing the process group (`process.kill(-pid)`; both shells are spawned `detached`) or
+`exec sleep 60` in the shell would end the child along with its parent.

+# Row 249 build notes (Gizmoduck)
+
+Gitea #1751, Vikunja P19 445 under #436. Brief: docs/plans/2026-10-20_host-credentials.md, section
+"Machine grant row b follow-up: the undo can't prove the remote add has ended" (6de1ebc62). Reviewer
+Duckworth, gate owner Sage. Branch gizmoduck/row249-on-8a04, on row 248's landing 8a04f4aa4 (sage-2012).
+No file under packages/bus/src changed between 6d5545d44 and 8a04f4aa4, so the brief's src line numbers
+hold on the base. Line numbers below are on this branch.
+
+## Correction to the brief
+
+The brief, copying gizmoduck-0139, puts the sweep's host-unknown refusal at broker.mjs:1350. On
+6d5545d44 it is :1349. On this branch it is :1354.
+
+## The change
+
+`#runHostGrant` in packages/bus/src/broker.mjs:
+
+- :943 adds `installed = false` next to `installing`.
+- :956 sets `installed = true` on the line after `await this.#hostGrant.install(...)`, before the
+  `stop()` that follows it. An abort that lands after install returned still ends revoked, with no hint,
+  because install returning means every request it sent has exited.
+- :1025, in the catch, inside `if (installing)` and after the remove: `if (!installed) extra =
+  { hostLineLeft: tag };`. The remove still runs first and its result doesn't matter. A remove that
+  throws sets the same hint as before (:1021).
+
+The rule keys on install not returning, not on `signal.aborted`. That covers an abort (host-run.mjs:136,
+SIGKILL to the local group), a timeout (host-run.mjs:131-134, SIGTERM, then SIGKILL after `graceMs`) and
+a dropped connection, which fails the request with no signal at all. `#hostGrantFailed` (:845) already
+adds "A line tagged X may be left on the host. Run: mosaic hosts sweep <host>" when `hostLineLeft` is
+set (:852), so the message needed no change.
+
+False hints. install is one call that runs `list`, maybe `remove`, then `add` (host-grant.mjs:329-333).
+Any failure inside it now records the hint, including a `list` that exits 1 before any add was sent, and
+an abort that lands before the first ssh starts (the G23 X5 case at "a revoke right after the spend").
+The brief accepts this for an add that exits nonzero. The other cases are the same kind: the line isn't
+on the host, and a sweep that doesn't list the tag drops the hint (G24, "a left tag no longer on the
+host", broker.mjs:1358). Narrowing it would need install to report which request was in flight, which is
+a change to host-grant.mjs's API that the brief doesn't ask for.
+
+## Row a's enroll
+
+The race can't happen there, because enrollment sends nothing to the host. `#runEnrollment`
+(broker.mjs:772-842) writes the record, calls `this.#hostGrant.enroll(business, host)` (:800) and
+commits the fingerprint. `enroll` (host-grant.mjs:247-286) runs ssh-keygen locally and writes the
+private half to its file. It opens no ssh session. The installer line goes on the host by hand: the
+notice tells ops-01 to write it, then to run `mosaic hosts check`. The undo at :835 is `unenroll`, which
+deletes the local key file. There is no remote add to outlive a kill, and no remote undo to race with.
+
+## Tests
+
+packages/bus/tests/grant-executor.test.mjs:
+
+- `lateAdd` (:451) is the shared tail. After the grant ends it asserts the code, `hostLineLeft` on
+  grant.failed, the sweep line in the notice, and that the undo's remove was the last request. Then it
+  writes `release`, so the held add writes its line and exits 0, and waits for the line in `granted`. It
+  checks there's no record, `hosts.status` lists the tag in `hostLineLeft`, `hosts.remove` refuses
+  host-line-left, `hosts.sweep` returns `removed: [tag]` and the line is gone, then `hosts.remove`
+  succeeds.
+- :468, the abort case. `hold-add`, the human approves, the add holds, `abortClaim` aborts the
+  executor's claim. Ends revoked.
+- :480, the timeout case. A 30 s wait is too long for the file, and making the timeout an option would
+  add a src seam, so the test wraps `install` through `opts.wrap` instead. The wrapper passes install its
+  own AbortController signal, waits for `holding`, aborts it, which SIGKILLs the local ssh group as the
+  timer does, then throws as a timed-out request does. The executor's signal isn't aborted, so it ends
+  host-failed. Nothing under src changes for it.
+- G8 (:283) changes. fail-list and fail-add now carry `hostLineLeft` and the sweep line. noop-add fails at
+  verify, after install returned, so it keeps no hint and the old message.
+- The comment at :436 (:432 at 6d5545d44) now says `skip` makes the held add exit without writing and that a
+  killed session's add can still write. G13 has no such comment.
+
+Both new tests write `release`, so their held stub exits before `t.after` removes the dir. Row 248's dir
+check (:67, :72) is the backstop.
+
+## Mutant
+
+/mnt/storage/scratch/gizmo-235-out/mutants-249.py, on row 235's runner. C1 removes the :1025 line and
+runs grant-executor.test.mjs. Both new tests and G8 should fail under it. `--check` matches its anchor
+once.
+
+## Runs
+
+On Sage's grant sage-2015, at 8457af076 (7cee1a1ab plus this file), TMPDIR /mnt/storage/scratch/g249t:
+
+| Run | Window | Result |
+|---|---|---|
+| grant-executor.test.mjs whole | 13:29:01-13:29:21Z | 39 of 39 pass |
+| C1 | 13:29:21-13:29:40Z | killed: both row 249 tests and G8 fail on `hostLineLeft` undefined |
+
+After C1 the worktree was clean and broker.mjs matched HEAD. After the runs, no node, sshd or sh process had a
+cwd under the worktree or g249t, and no `fake/add` or `fake/remove` stub was running. The bus suite runs on
+Sage's gate.
+
+## Rebase onto 8a04f4aa4 (sage-2012)
+
+The first commit, 02bfd184b, sat on bc579f7a8 as gizmoduck/row249, which was never pushed. Row 248 landed
+as 8a04f4aa4, changing grant-executor.test.mjs at :54, :67 and :72. gizmoduck/row249-on-8a04 starts at
+8a04f4aa4 and cherry-picks 02bfd184b with no conflict. 248's lines stay as landed. The patch-id is the
+same on both (c33823941e61). Test line numbers moved down by one, and this file was updated for that.

+# Row 247 build notes, C2-20b persona import follow-up (#1749)
+
+Brief: docs/plans/2026-10-20_case2-rows.md "C2-20b persona import follow-up: printed keys, the dry run
+fence check and the mkdir race", landed in 335bb3e30. These are Webby's row 221 notes N1, N2 and N4
+(webby-0073, REVIEW-r1 a0a00630e on webby/reviews). N3 is in DEFERRED (sage-1941).
+
+## Base
+
+Branch gosalyn/c2-20b from 335bb3e30, which is row 221's landing 300766450 plus the brief.
+
+## What changed
+
+- N1, `scripts/case2-persona-import.mjs`: the per-channel prompt line prints the platform key, with its
+  fixed `platforms.` or `gateway.platforms.` prefix, and the channel key through `JSON.stringify`. A key
+  holding a newline prints as `\n` inside one quoted line. The profile name on that line is not config
+  text: `pairing` already holds it to `PROFILE_ID`.
+- N2: the dry run calls `personaTextFault` on each persona after its count line. A fault prints as
+  `profile P: persona <reason>, so C2-08's fence would refuse it`, where the reason is the fixed string
+  `personaTextFault` returns, never persona text or a line number. With any fault the run refuses, exit
+  1, and writes nothing, as stage would. The header comment no longer says a fault is counted, not
+  refused, and now says a SOUL.md over four times the fence in bytes refuses before any count, which is
+  what `soul()` already did (Webby's second point under N2).
+- N4: `privateDir` catches an EEXIST from its mkdir and refuses with `<path> was made by something else
+  between the check and mkdir`. Any other mkdir error is thrown as before, since the brief names only
+  EEXIST.
+- Tests, `packages/cli/tests/case2-persona-import.test.mjs`:
+  - The per-channel prompt test expects the quoted keys.
+  - New: a chet config.yaml with a newline in the platform key and in the channel key prints one quoted
+    line, and no output line starts with the forged text.
+  - The dry run heading test now expects the fence fault line, exit 1 and the refusal, still with
+    nothing written. Its persona has two heading lines, which the fence refuses.
+  - New: a persona of 8001 two-byte characters, 16002 bytes and under the 32000 byte cap, makes the dry
+    run print the over 8000 characters fault, write nothing and exit 1. At exactly 8000 it exits 0.
+  - New: the mkdir race refuses by name at stage, for the staging directory, and at install, for
+    `personas/<business>`. Each refused directory is left empty.
+- New fixture `packages/cli/tests/fixtures/case2-persona-import/mkdir-race.mjs`, an `--import` preload
+  like `trace.mjs`. It makes the directory named by `$PERSONA_MKDIR_RACE` just before the script's own
+  `mkdirSync` of that path, so the script meets a real EEXIST from the kernel, not a thrown stub.
+
+## Known limit of N1
+
+`JSON.stringify` escapes C0 controls, `"` and `\`, but leaves DEL, C1, U+2028, U+2029 and the bidi
+controls raw. None of those ends a line on a terminal, so the forged line N1 names can't happen. A bidi
+control could still reorder how the rest of that one line displays. The brief asks for `JSON.stringify`,
+and Sage kept it in sage-1964 because the keys come from Jason's own Hermes config. Note for Webby: row
+231's `quote()` in packages/library covers the wider set, and this row doesn't import it. If you want it,
+ask for it in review.
+
+## Mutants
+
+One per fix, plus a second for N1 so each of its two keys has its own. Each replaces one exact string
+in the script, runs the test file, then restores the script from a copy and checks its sha256.
+
+| Mutant | Fix | Change |
+|---|---|---|
+| M1 | N1 | the channel key prints raw |
+| M2 | N1 | the platform key prints raw |
+| M3 | N2 | the dry run's refusal after a fault is skipped |
+| M4 | N4 | privateDir's EEXIST branch never matches, so EEXIST is thrown raw |
+
+## Outside readers
+
+`git grep` over packages/*/tests/* and scripts/test-*.sh finds `case2-persona-import` only in its own
+test file and in two files of its fixture tree, README.md and trace.mjs, which name the test file in a
+comment. No test pins a hash of the script.
+
+## Tests
+
+Two slot runs, `busy.sh && run.sh` in /mnt/storage/scratch/gosalyn-r247, on the test file alone.
+
+Run 1, grant sage-1969, 11:47:45Z to 11:48:00Z, was red: 14 tests, 12 pass, 2 fail. The fault was in the
+script. Adding `JSON.stringify` to the per-channel line dropped the space after the comma, so it printed
+`"-1001",29 bytes`. The two per-channel tests caught it. run.sh also went on to the mutants with a red
+base, so their counts meant nothing. Sage approved both fixes in sage-1971: the space goes back, and run.sh
+now exits 3 before the mutants unless the base is rc=0 with fail 0.
+
+Run 2, grant sage-1971, 11:49:04Z to 11:49:22Z, was green: 14 tests, 14 pass, 0 fail, rc=0.
+
+| Mutant | Line | rc | Failed | Killed by |
+|---|---|---|---|---|
+| M1 | 237 | 1 | 2 | the per-channel prompt test and the newline key test |
+| M2 | 237 | 1 | 2 | the same two |
+| M3 | 238 | 1 | 2 | the dry run fence test and the dry run heading test |
+| M4 | 192 | 1 | 1 | the mkdir race test |
+
+After the run the script's sha256 was 7031d2c0dc9bd22bc748b364a35b461fc01cb98b795032a2e0ec436f3188d4e4, the
+same as the copy taken before it. The /proc scan found no process in the worktree or the scratch dir.

+# Row 197 execution ledger
+
+Plan: MANIFEST.md r2, approved by Webby ca6b32d66.
+Build grant: sage-1390. Suites, image builds and paired proof are not granted.
+Rebased five documentation commits onto origin/refactor aa1bd209e before code.
+Existing worktree herb/row197 and plain node_modules symlink retained.
+
+- T1 preflight/steps: in progress.
+- T2 locks/status/recovery: pending.
+- T3 image/Docker: pending.
+- T4 fixtures/timing: pending.
+- T5 evidence/acceptance: historical timing done; implementation pending.
+
+Preflight interfaces: T1 RunPaths supplies T2 ownership and T3 image checks.
+T2 run receipt supplies T4 lane/port state and T5 attribution. T3 image identity
+is checked before Docker-bearing steps. T4 timings supply T5 pair summaries.
+No interface conflict found. No product API or assertion changes are authorized.
+
+Ruling: use this approved BUILD.md as the execution ledger, rather than adding
+skill workspace paths outside the manifest. This preserves the reviewed path
+boundary. Missing ledger detail would cost recovery time, not product behavior.
+
+## Implementation checkpoint 2026-10-20T20:11:58Z
+
+T1-T5 source is present within the approved manifest. Full acceptance is pending.
+Fresh single-file checks: preflight/supervisor 6/6; state/recovery 11/11; image and
+Docker guard 4/4; port leases/attribution/proof summary 3/3. No skips or failures.
+Existing files checked singly: board serve; WebUI serve, preview, proof-cli,
+tester-cli and service; harness pi and Claude. Stack-release R1 selected single
+passed 1/1. WebUI service also passed 31/31 with lane-a leases and a 30-byte root.
+All existing assert lines are unchanged. Shell syntax and diff checks pass.
+
+Observed defects fixed during the single-file cycles: cancellation incorrectly
+returned zero when a TERM handler exited zero; recovery did not supersede an
+unclean terminal; status omitted the lock-before-receipt window. Evidence logs
+retain the failing and passing observations. Source still has no commit because
+applicable suites have not run. No image build, proof, push or live operation.
+
+Ruling: use an instrumented single-lane author gate on a frozen dirty-source
+clone before committing source. The new wrapper requires a clean candidate and
+proven image receipt, while repository rules require green suites before source
+commits. The author gate retains every suite and assertion, caps concurrency at
+two, uses own port/state/temp/project roots, and guards Docker against builds.
+Cost if wrong: the author gate fails; clean-candidate wrapper baselines and the
+paired proof remain mandatory after source is verified and committed.
+
+Ruling: publish the initial run directory atomically after the start receipt is
+complete. This avoids a second lane observing a partially written start. A
+crash before publication has started no test or mutable Docker operation.
+Cost if wrong: a lane refuses or quarantines; no protected state is bypassed.
+
+## Implementation review corrections, 2026-10-20T20:33Z
+
+Webby-0029 reviewed the first implementation packet at f942bd7d4.
+B1 identified missing manifest tests. B2 identified a test that leased both real
+bands through a private lock namespace. The old author-gate clear was withdrawn
+in herb-0019. SOURCE.json, BUILD.patch and gate.sh still describe the old frozen
+clone. They are not a clear for the edited working tree. No author gate ran.
+
+B2 correction: the helper test uses only the active lane and MOSAIC_GATE_STATE.
+It compares the other band arithmetically and has no unasserted listener. The
+occupied-port probe first obtains its own real lease, binds that port, and
+asserts that its sentinel listener survives refusal. No test reserves another
+lane's band. Exhaustion narrows only the test process's band to one owned port.
+
+B1 coverage added within the existing approved paths. No case is dropped:
+
+| Manifest case | Added check |
+| --- | --- |
+| T1 canonical and builder checkout, existing output | gate-lane.test: direct validateRun refusals |
+| T1 92-byte socket and over-107-byte socket | exact design example with a distinct gt- test root; 108-byte refusal |
+| T1 both candidates carry tooling | validateTooling compares each launcher file, including missing and changed cases |
+| T1 duplicates and NODE_TEST_CONTEXT | repeated package/script fixture is retained; sanitized environment is exercised by both supervised children |
+| T2 one-winner race and inherited FDs | two actual shell wrappers race; a controlled supervisor verifies held FDs, and its child checks that no FD points to either lock file |
+| T2 same checkout and legacy claim refusal | activeConflicts uses synthetic process observations with a live lane and a sibling landing gate |
+| T2 surviving child and interrupted recovery | locked recovery kills a child proven by the private root, preserves a foreign child, is killed during fake Docker cleanup, leaves quarantine, and resumes under a new fixture grant |
+| T3 missing receipt and missing image | verifyImage refuses absent provenance and failing inspection |
+| T3 tag changed mid-gate and at gate end | runGate now uses the same executePinnedSteps boundary exercised by the tests; the next step never runs after a changed ID |
+| T3 mutable-tag rebuild | fake preparation returns a new image ID with identical input digest; the old receipt refuses it |
+| T3 cold and warm counters | preparation records one build and its time; warm execution records zero builds; repeated verification never builds |
+| T4 parallel test-file leases | two generated Node test files hold ports in the same lane/state; locks are checked during child execution and shutdown |
+| T4 exhausted band, occupied port and foreign listener | a one-port process-local band refuses both a held lease and an existing sentinel listener; the listener survives |
+| T4 owner death | a killed allocator releases only its own holder; a foreign lease remains held |
+| T4 lease through child shutdown | parent probes the lock while the fixture test runs and after its child has stopped |
+| T4 fixtureCacheEnv | replacement child environment writes only under separate tmp, jiti and cache directories |
+| T5 unrelated session append | a separate process waits for a running-step barrier, appends under a fixture HOME, and remains unrelated in the resulting metadata attribution |
+
+N1 removes the unused closed binding. All leases reserve an unbound endpoint;
+existing closed options need no call-site change. N2 makes child TMPDIR a tmp
+subdirectory. N3 normalizes ss interface scopes before checking port 9. N4 uses
+gt- for unit run roots. N5 documents the canonical node_modules dependency.
+N6 is recorded: row 200 also edits stack-release.test.mjs; the second landing
+must rebase and rerun that file singly. Sage was told in herb-0019.
+
+Before Sage's hold, expanded preflight tests passed 11/11, state tests 14/14,
+image tests 7/7, and the pi/Claude singles passed 8/8 each with separate tmp
+subdirectories. Later source/test edits still need verification. In particular,
+the new parallel test-file probe had a cleanup-order defect and is unverified.
+Its root cleanup ran before child shutdown. Cleanup now stops children before
+removing their root. Output is retained for a useful failure report. The initial
+FD probe also assumed Node did not reopen FD numbers; it now checks the actual
+lock targets. The early passing fixture file covered child allocators, before
+they were changed to actual generated test files. It is not acceptance of the
+latest file.
+
+Sage-1448 stopped all node --test runs at 20:30Z for Rocko's browser slot.
+The remaining owned process tree was stopped at 20:30:32Z. Inspection found no
+remaining owned test processes afterward. Edits and static inspection continue.
+20 module syntax checks, shell syntax and git diff checks pass. Existing-file
+assertion lines remain identical to HEAD. No test is run during the hold.
+
+Next: after Sage passes Rocko's clear, verify the corrected files singly,
+including a lane-env helper-file check. Then refresh the frozen clone and all
+three packet artifacts, send their hashes, and request a new author-gate clear.
+Suites, image builds and paired proofs still need their own grants. No source
+commit, push, suite, real Docker build or paired proof has run in this phase.
+
+## Refrozen review packet, 2026-10-20T20:41Z
+
+Sage-1454 lifted the single-file hold. Fresh runs passed without failures or
+skips: review-t1-resume.log 11/11, review-t2-resume.log 14/14,
+review-t3-resume.log 8/8, review-t4-resume.log 8/8. The helper file also passed
+8/8 with lane-a environment in review-t4-lane-a.log. Its retained state had only
+an a port-lock namespace, no b directory, and every lock was released. Generated
+fixture Node test entries explicitly use --test-concurrency=2. The child-test
+probe now finishes and cleans up before removing its root. All 41 new tests pass.
+
+B1 and B2 fixes are ready for Webby's review. No manifest case was dropped.
+All 25 source paths were copied to a new frozen clone and compared by mode and
+SHA-256. This supersedes the earlier withdrawn source packet:

+## Implementation approval and final notes, 2026-10-20T20:47Z
+
+Webby-0031 approved r2 in REVIEW-impl-r2.md at 1f404c973. Their static review
+verified every source hash/mode and patch result, and all B1/B2 cases. No queue
+review request comment exists yet; Sage owns creating it if needed.
+
+Folded all three optional notes into the same approved paths. The helper file's
+standalone fallback now shares /mnt/storage/scratch/mosaic-gate-lanes with real
+lane-a leases and leaves its stable lock files in place. Band assertions use the
+imported BANDS. Both T5 polling children fail after five seconds if their barrier
+is missed. README records the shared standalone namespace and deadlines.
+
+Fresh single-file logs review-r3-fixtures.log and review-r3-lane-a.log both pass
+8/8 with zero skips. The lane-a run has no b lock directory, and every lock was
+released. Syntax and diff checks pass. No existing test assertions or timeouts
+changed. Remaining source matches the 11/14/8-file checks from r2.
+
+Refreshed all 25 source rows in the existing frozen checkout. New digests replace
+the preceding r2 packet. gate.sh and its command are unchanged:

+Author gate remains unstarted and queued for Sage's explicit grant. No source
+commit, suite, image build, paired proof, push or branch deletion ran.
+
+## R3 approval receipt
+
+Webby-0033 approved r3 in REVIEW-impl-r3.md at a5643f9bd. Static review verified
+the three packet hashes, all 25 source rows, and the patch result. Their review
+accepts N1-N3; no additional hang-guard test is requested. No queue review request
+comment exists yet, so Webby has not recorded a queue review.
+
+Read-only verification after receipt confirms that the approved packet hashes
+and all 25 worktree/frozen source hashes and modes still match. Source and gate
+script stay frozen. The author gate has not started and still needs Sage's grant.

+The move succeeded at revision 2395, opening round 1 on #1695. The request post
+failed before send because MOSAIC_GITEA_CREDENTIAL_FILE is not set; revision 2396
+records the failed outcome. Exit code 1 describes the failed post, not a failed
+row transition. Read-back confirms state in-review and the correct candidate.
+Sage will post as jarvis and give Webby the request comment number. No credential
+lookup, alternate post or retry was attempted here.
+
+SOURCE.json, BUILD.patch, gate.sh and all 25 frozen source rows remain unchanged.
+Latest slot order is row 190 r2, 201, 204, 200, Gander, then Herb. No gate starts
+before Sage sends an explicit grant ID.
+
+## Follow-on assignment
+
+Sage-1503 assigns row 215, Case 2 C2-04, to Herb after row 197 (queue rev 2455,
+Gosalyn design r11). Read docs/plans/2026-10-20_case2-rows.md, C2-04 section,
+at 5b8def2f1 when starting that row. Its required base is origin/refactor
+305857c8f. This assignment does not replace row 197 or authorize its gate.
+Keep row 197's approved source frozen while awaiting Sage's grant. Start row
+215 only after row 197, using a new branch name under the existing fleet rule.
+
+## Round 2 merge preparation on row 233
+
+Sage-1757 replaces history replay with one candidate commit on 57f59e0c3.
+The attempted history replay on herb/row197-r2-233 had already finished when
+that instruction arrived. Its only conflict was the append-only BUILD-LOG tail.
+That branch remains for history; none of its replayed commits is in this round.
+The current branch is herb/row197-r3-233, directly from
+57f59e0c399ce29b1bb85ca6af686fdc10eb195d.
+
+Stash correction: shared refs/stash was used incorrectly. The exact entry
+2767b88549dfd8c7e810908b5416876fa50cb571 is now kept on
+herb/row197-r3-wip. After verifying stash@{0} still named it, only that entry was
+dropped. The two other entries remain. No further stash creation, force push,
+branch deletion or refs/stash mutation is planned. A separate working-copy
+backup is /mnt/storage/scratch/herb197-merge-W4oiLg.
+
+Sage-1760 requires preserving every landed hunk on every changed manifest path.
+Checked each of the 25 r1 paths with git diff aa1bd209e 57f59e0c3 -- PATH.
+Exactly three changed upstream. Their r2 diff against 57f59e0c3 is captured in
+r2-merge-only.patch:
+
+| Merged path | Only row 197 changes against landed base | Landed content retained |
+| --- | --- | --- |
+| packages/cli/tests/stack-release.test.mjs | leasePort and laneAfter imports; freePort now calls the lease helper | All landed tests, including row 233's tests after R15 and BACKUP_STORE checks |
+| packages/webui/tests/service.test.mjs | leasePort and laneAfter imports; closedPort now calls the lease helper | SEND_REFUSAL permits --sso; default unit rendering removes the @CONFIG_ENV@ line |
+| scripts/test-discord.sh | fixture PI_CODING_AGENT_DIR setup; optional two-worker nested Node cap | Row 190's absent scratch MOSAIC_CONFIG selection and caller-config restoration |
+
+The other 22 paths equal the r1 reviewed source bytes and modes. r2-MERGE.json
+lists every path, its r1/r2 digest, mode, upstream-change flag and equality result.
+Source copies came from the hash-verified r1 frozen checkout. Original r1 digest:
+6318f0d0bba9ee90ccaa3503cac8c2e04c6397f2ef6c3564f687fbc2092989e3.
+No existing assertion or timeout line differs from the landed base. Static
+checks only: 20 module syntax checks, four shell syntax checks and git diff check
+pass. BUILD-LOG.md equals 57f59e0c3 byte for byte and is outside this commit.
+
+Sage explicitly requested the local candidate SHA before granting tests. This
+commit is an untested preparation checkpoint, not gate evidence. No tests or
+push are authorized yet. r2-TEST-FILES.txt lists the requested grant scope:
+16 Node test files singly and scripts/test-discord.sh, test-foundation.sh and
+test-queue.sh. The four stack-release consumers are stack-release.test.mjs,
+stack-release-external.test.mjs, stack-upgrade.test.mjs and stack-instances.test.mjs.
+The shared stack-release-fixture.mjs is exercised by its importing test files,
+not run as a standalone test. This covers all 13 touched Node test files plus
+three additional stack-release consumers and all three touched shell suites.
+
+Current slot order from sage-1760: Gizmoduck, Launchpad, Darkwing, then Herb,
+around 06:30Z. Wait for an explicit grant. After granted checks and authorized
+push, build the new candidate manifest from that pushed tip and open the
+merge-scoped round 2. Old SOURCE.json, CANDIDATE.sha256 and gate.sh remain r1
+historical artifacts and are not a clear to run the merged candidate.
+
+## Round 2 rebuilt on row 234
+
+Sage-1776 names landing c771a36f4bd0b6c359282425c668996a90072f93.
+Built a new branch, herb/row197-r4-234, directly from that landing. No history
+replay, stash, force push, branch deletion, test run or push is involved.
+The prior candidate a3b7cbde8 remains untested and is not the queued candidate.
+
+Checked git diff --name-only 57f59e0c3 c771a36f4 against all 25 source paths.
+Only packages/cli/tests/stack-release.test.mjs overlaps; the other 24 do not.
+The full comparison is in r2-on234-OVERLAP.txt. The stack-release file starts
+from the landing and keeps both T46 untimed entries, host_grants and hosts.
+Its only changes against the landing are the leasePort and laneAfter imports
+and freePort's call to the lease helper. r2-on234-merge-only.patch records those
+hunks. Existing assertions and timeouts match the landing exactly.
+
+Every other source path equals a3b7cbde8 byte for byte and retains its mode.
+This includes the previously merged service and test-discord files, preserving
+all landed --sso, CONFIG_ENV and scratch-config handling. The earlier evidence
+r2-MERGE.json still records those three pre-234 merge cases. The new
+r2-on234-MERGE.json records each current digest, prior digest, mode and equality
+result. BUILD-LOG.md equals the new landing byte for byte and is excluded.
+
+Static check of the changed Node file and the candidate diff pass. No tests
+were run. The scope stays r2-TEST-FILES.txt: 16 Node files singly plus the three
+shell suites. No manifest or queue round is rebuilt until granted checks and
+authorized push. Old SOURCE.json, CANDIDATE.sha256 and gate.sh remain historical
+r1 evidence. The test slot follows Darkwing 240 and needs Sage's explicit grant.
+
+
+## Round 6 preparation (sage-1883, mos-1162)
+
+New branch herb/row197-r6 starts at fefd54e13, after the standalone row
+212 landing ee7b2f137. No r5 manifest path changed between e7078e6a8 and
+this base; all 32 r5 blobs and modes were copied intact before the two
+umask changes. No history replay, stash, force push or branch deletion.
+
+executeSteps now launches each argv through /bin/bash with umask 022
+and exec, preserving the process group and argv boundaries. The supervisor
+and gate-lane.sh retain 077, including state, locks, private logs and roots.
+New gate-lane tests assert the actual child umask and created file mode,
+the unchanged parent mask, private log mode, and actual wrapper-created
+state/lock modes. No shell, image preparation, credentials test or other
+existing assertions changed. process.test.mjs equals the landed base;
+lane-image.mjs equals r5. N7 remains DEFERRED at fefd54e13; rows 243 and
+244 own the explicit chmod and PI_AUTH_FILE fixtures respectively.
+
+Read Sage's permitted failed pkg-bus log: process.test startup token refusal
+saw ready.ok true, consistent with inherited 077 narrowing its fixture mode.
+No further diagnostic read of the retained ga-8I3iZc root is needed.
+No r6 tests or probes have run. Source commit, push and new manifest await
+the explicit granted checks. r6-OVERLAP.json records the empty overlap.
+
+
+Sage-1892 focused grant: gate-lane.test whole 13/0, process.test whole
+through executeSteps 8/0, zero skips/cancellations. Syntax checks passed.
+All new umask/mode assertions passed. No Docker, image, lane or proof run.
+Empty /proc cwd/argv scan and removal recorded in r6-granted/cleanup.json;
+clear herb-0068 at 09:21Z. The source matches r5 on 29 of its 32 paths,
+including modes. Only BUILD.md, gate-lane.test.mjs and gate-lane.mjs differ.
+The new r6-OVERLAP.json records the base comparison. No process test edit.
+Sage-1895 authorizes one source commit and seat-only push after range check.
+
+
+## Round 7 preparation (sage-1951, sage-1955)
+
+The r6 proof passed all package suites with the original process.test,
+then failed script-release. The guard injected --no-build into compose run;
+Compose 5.5.1 rejects it before container creation. The old unit test only
+asserted the same invalid argv, so it could not detect this compatibility
+error. This supersedes no-build-flag claims in the historical packet.
+
+herb/row197-r7 starts at b1fece6f0. No r6 manifest path changed between
+fefd54e13 and this base; all 33 r6 blobs/modes were copied intact before
+r7 tests were authored. No history replay, stash, force push or deletion.
+Sage-1955 accepts the private tempRoot/compose-no-build.yaml override,
+mode0600, with build: !reset null and image pinned to the receipt's imageId.
+The guard owns the -f arguments and forces run --pull never --no-deps.
+Caller-supplied Compose config/build/pull options remain refused.
+The existing proof removes successful temp roots and retains failed roots;
+the override stays within that same cleanup ownership.
+
+Tests first: installed-binary run --help before SERVICE checks parser
+acceptance without starting a container. A separate compose config --format
+json check uses the actual candidate compose.yaml, made-up env/auth paths,
+and an empty Docker config directory, asserting no build key and the exact
+pinned image. The no-build-restoration mutant must fail that parser test.
+No test, probe or Docker command has run on r7; waiting for Sage's grant.
+
+Primary references: Docker's merge reference documents !reset null:
+https://docs.docker.com/reference/compose-file/merge/#reset-value
+Docker's run reference documents --pull and --no-deps, with no --no-build:
+https://docs.docker.com/reference/cli/docker/compose/run/
+Installed 5.5.1 acceptance and merged configuration are still unverified.
+
+
+Sage-1956 focused grant, 2026-10-21 11:19-11:21Z: busy check CLEAR.
+Whole gate-lane-image.test on the r6 guard: 9 pass, 2 fail. The installed
+Compose parser emitted unknown flag: --no-build; the other expected failure
+was the missing override helper. No cancellation or skip. After the fix,
+whole file 11/0. The committed r7-no-build.mutant.patch restores the invalid
+flag. Applied only for the installed parser regression: 0/1 with the same
+unknown-flag error, killed. Restored source and whole file passed 11/0 again.
+Both approved node --check commands passed. Empty /proc cwd/argv scan;
+clear herb-0073 at 11:21:04Z. No container start, image build, lane, proof or
+full suite ran. Logs/counts/scan are in r7-granted/ (local run evidence).
+
+The guard supplies both absolute -f paths, suppressing automatic override
+selection, pins receipt imageId, removes build via !reset null and adds
+--pull never --no-deps. Its main entry publishes the override before Docker
+runs. A unique private staging file plus hard-link publication prevents
+partial writes or replacement under concurrent guard calls; existing bytes,
+mode0600, file type and ownership must match, with O_NOFOLLOW on reads.
+The file stays under the run's short private tempRoot for existing proof
+cleanup. Caller Compose options remain allowlisted and config/build/pull
+options refuse. The actual installed Compose config test reports no build
+key and the exact image ID; parser help is before SERVICE, so no container
+operation can run. Fixtures supply made-up env/auth paths and empty Docker
+configuration. Existing image provenance, cleanup and umask behavior remain.
+
+Range check: one source commit on b1fece6f0, same 33 r6 paths plus the
+mutant patch and r7 overlap receipt (35 paths). Thirty r6 paths retain the
+same blob/mode. Only lane-docker.mjs, gate-lane-image.test.mjs and BUILD.md
+differ from r6. process.test and BUILD-LOG equal the landing. No force push,
+branch deletion, history replay or other source edits. Sage-1956 authorizes
+the source commit and seat-only push; fresh proof remains Sage's action.
+
+
+## Round 8 preparation (sage-1979)
+
+The r7 D5 proof passed business and bus, then failed the two installed
+Compose probes in pkg-cli. Their subprocess fixture retained the lane's
+shim-leading PATH but omitted MOSAIC_GATE_DOCKER_RECORD, so the shim read
+an undefined path. This is a test context error; the production guard stays
+byte-identical to r7.
+
+New herb/row197-r8 starts at 5c6f73ed7. None of r7's 35 manifest paths
+changed from b1fece6f0 to this base. Tests choose the record's real absolute
+Docker path when a lane record is set; outside lanes they keep using docker.
+Only the two read-only help/config probes use this helper. The subprocess
+env still holds fixture-only configuration; the record need not propagate
+to it. No run or policy allowlist is widened.
+
+Sage-1979 grants 215's 16 singles first, then r8's normal and lane-shaped
+shim-leading PATH whole-file checks and the record-lookup-removal mutant.
+The shim fixture invokes the actual unchanged guard, with a private made-up
+record naming the real Docker binary. No image build, container start, lane
+or proof is part of r8 checks. No r8 checks have started yet.
+
+
+Sage-1979 r8 checks followed 215's early singles, then clear herb-0078 at
+2026-10-21 12:09:28Z. Whole gate-lane-image.test normal PATH11/0; whole
+actual guard-shim-leading PATH plus private record11/0. The committed
+r8-record-lookup.mutant.patch removes the lookup: installed-Compose argv
+regression0/1, killed with the original Received undefined path error.
+Restored code, repeated whole shim-PATH file11/0. All zero skips/cancellations.
+Logs/counts/fixture metadata/empty /proc cwd+argv scan are in r8-granted/.
+Both 215 and r8 private roots were removed after an empty process scan.
+No image build, container start, suite, lane or proof ran for r8.
+
+Range: one commit on5c6f73ed7. Of r7's35 paths,33 keep the same blob/mode;
+only gate-lane-image.test and this BUILD.md change. The r8 mutant and overlap
+receipt are added. The production guard and all other tooling match r7.
+BUILD-LOG and process.test equal the landing. No history replay, force push,
+branch deletion, live state change or policy widening. Fresh proof remains
+Sage's action after Webby's merge review.

+- Proof 4, pair1-b, pkg-conversation, K12 (`cohort.test.mjs:292`): `populated` undefined. Row 250, Vikunja #450.

+## SETUP-SHEET.md
+
+| Claim | Source |
+|---|---|
+| She keeps writing in Obsidian, obsidian-git pushes to git.mosaicstack.dev, nothing changes on her machine, nothing commits to her repo | D:939-940 (7.1) |
+| Agents read what she pushed; a push reaches them in about a minute | D:1006-1007 (7.5); D:972-973 (60-second sync timer) |
+| Agents read `.md` notes inside book folders only | D:457-461 (1.2); `packages/library/src/scope.mjs:9-19` |
+| Not read: top-level notes, `.canvas`, `.base`, attachments, anything outside a book folder | D:461 |
+| Other repos under `~/src` are not read | D:489 (1.3), D:494-497 (N4) |
+| Agents can't write to her repo: canon, playground, anything | D:389 (D3); D:1008 |
+| Folder roles live in the `projects` entry of the business file, hand-edited, agents can't change it | D:409-429, D:443-451 (1.1, M9) |
+| Jason asks her to confirm the mapping first | D:431; D:1324-1328 (10 step 7) |
+| A folder named in `playground` is her playground | Brief:22; D:434 |
+| Each playground prefix sits inside one book folder | D:434-436; `packages/library/src/mapping.mjs:77-80` |
+| One per book, e.g. `<book>/playground/`; until then everything mapped is canon | D:438-439 |
+| Agents search canon unless they ask for the playground | D:463 |
+| Playground may back an idea or question, not a fact, finding or correction; refused before she sees it | D:858 (`playground-cited-as-canon`); D:378-382, D:835-839 (guard runs before store) |
+| Only the folder decides; a tag or property can't change scope | D:388 (D2); D:440-441; `scope.mjs:1` |
+| Graph colour group via Groups and a `path:` query, her own vault setting, changes nothing for agents | Brief:23; D:941-943. Obsidian UI steps from the task prompt, not the design |
+| Path starts with the books repo folder because the vault is `~/src` | D:939 |
+| N2: moving a note into a book folder makes it canon, agents may cite it as fact | D:944-945; D:259 |
+| Rough drafts outside the playground are canon | Inference from D:460 (scope rule) |
+| N4: Obsidian resolves short links across `~/src`, the reader sees one repo, the two can differ, the reader can't tell | D:494-497; D:262-263 |
+| A name only in another repo leads nowhere for agents | D:489 (R4); `packages/library/src/links.mjs:61-87` |
+| A full-path link resolves the same in both | D:497-498. Hub side: `links.mjs:77-78` (`vault-prefix` step) |
+| "New link format: Absolute path in vault" setting | Obsidian UI knowledge. Not in design or code. Reviewer may strike it |
+| `appears_in` and `relationships` links are read as links | D:489-490; `packages/library/src/reader.mjs:15`, `:153-162` |
+| Quoted flow list `["[[A]]", "[[B]]"]` parses | `reader.mjs:81-96` (flow), `:66-73` (quoted scalar), `:159` |
+| Block list with quoted items parses | `reader.mjs:117-122`, `:66-73` |
+| Unquoted `[[[A]], [[B]]]` is R3 | Brief:28-29; `reader.mjs:87` (bracket inside a flow list stops parsing), `:137` |
+| R3 effect: whole front matter unread, note still indexed by path, name and body, listed as a problem | D:480; `reader.mjs:103-105`, `:193`; `packages/library/README.md:69` |
+| Problems show in Mosaic's status | D:473-474; D:999-1000 (7.4 status line) |
+| A value without `[[ ]]` is a name | D:489-490; `reader.mjs:159` |
+| Bean and Chet keep names and personalities | D:660-661 (Q180) |
+| Hermes: free text and story text. Mosaic: short cited items, a prose request gets a question or idea | D:778-781 (design 4) |
+| Bean and Chet's item kinds: idea, question, finding, fact; web cites allowed | D:649 (`companion`); D:860 (`citation-unfetched`) |
+| Limits 10 items, 5 ideas of 200, others 300 | D:819 (M5) |
+| She or Jason can ask for lower limits | D:1329-1330 (10 step 8); D:831 |

+
+## Code and design disagreements
+
+1. Design 1.1 shows the mapping nested in `"projects": {"books": {...}}` (D:412-429). The survey's
+   `--mapping` file must be the inner entry alone (`survey.mjs:114-116`). The run sheet follows the code.
+2. Design 1.3 calls `vaultPrefix` part of the mapping (D:418). The code makes it optional
+   (`mapping.mjs:48`, README:30). Without it, a full vault path link, the N4 advice, resolves to
+   nothing in the hub (`links.mjs:73-87`: `root` fails, `vault-prefix` is skipped, `shortest` refuses a
+   `/`). The setup sheet's full-path advice holds only when Jason sets `vaultPrefix` to her books repo
+   folder name.
+3. The task prompt calls the unquoted form "refused". R3 is not a refusal. It is a reported problem,
+   and the note stays indexed (D:473, D:480). The sheet says what happens instead.
+
+## Open questions
+
+1. Where `<repo>` comes from on .54. The survey reads a local repo's `HEAD` and never fetches. The bus
+   mirror needs C2-04 and C2-03a, neither landed. C2-03a moves `refs/heads/served`, not `HEAD`, so the
+   mirror's `HEAD` may name no commit and the survey would refuse with exit 2. The sync also needs a
+   checked mapping with at least one book (`mapping.mjs:59`, `:70`), and the mapping's values are
+   meant to come from this survey (D:431). Sage needs to rule: a placeholder mapping for the first
+   sync, a `HEAD` the sync sets, a `--commit` flag on the survey, or another source.
+2. The brief says Obsidian's property editor writes `appears_in: ["[[A]]", "[[B]]"]` (Brief:28-29,
+   webby-0041 N4). I didn't read webby-0041 or check Obsidian's output. Both the flow and the block
+   quoted forms parse, so the sheet shows both and says only that the editor adds the quotes.
+3. Whether `/srv/mosaic/.npm-global/bin/mosaic` exists on .54. The run sheet uses the copy's
+   `scripts/mosaic` by full path to avoid depending on a wrapper.
+
+## Sage's rulings on the open questions (2026-10-21)
+
+1. Survey source: the bus's bare mirror after the first `library.sync`, the only copy on the host
+   (design 2.1). The C2-03a brief now requires the mirror's `HEAD` to be a symbolic ref to
+   `refs/heads/served`, with a test (5c6f73ed7), so the survey reads the served commit with no ref flag.
+2. Property list forms: the sheet shows both quoted forms, since both parse. Webby checks the claim
+   that Obsidian's property editor writes the quoted form.
+3. The "New link format: Absolute path in vault" tip stays. It is an Obsidian setting, not a design
+   claim, and Webby may strike it.
+4. The run sheet calls the copy's `scripts/mosaic` by full path. That holds whether or not a wrapper
+   is on `PATH`.
+5. `vaultPrefix`: the run sheet's step 4 tells Jason to set it, because the setup sheet's full-path
+   link advice depends on it.
+
+## Round 2 (2026-10-21), from Webby's round 1 notes (webby-0075, rev 2848)
+
+- N1, by Mos's ruling mos-1165 (fix before landing): SETUP-SHEET.md now gives the 1,200 character
+  total of item text per reply (design M5, step 8). The word "Today" is gone. No code enforces these
+  caps until C2-06 lands, so my ruling is that the sheet goes to Melanie only after C2-06 lands, and
+  then only on Jason's go (#419). The wording stays as is, because by then it holds.
+- N2: SURVEY-RUN.md says tab, newline, carriage return, backspace and form feed print as `\t`, `\n`,
+  `\r`, `\b` and `\f`, and other control and bidi characters as `\uXXXX` (survey.mjs quote()).
+- N3: SURVEY-RUN.md has a refusal row for `library-commit:` (reader.mjs listTree). survey.mjs turns
+  every LibraryError into exit 2 with its message.
+- N4: SURVEY-RUN.md's new step 2 checks `command -v node` under the same sudo and PATH before the
+  survey runs.
+
+## Round 3 (2026-10-21), from Webby's round 2 note N5 (webby-0077, rev 2856)
+
+- N5: the library-commit row no longer says a moved `HEAD` causes it. The survey reads `HEAD` once,
+  and listTree raises library-commit only for an id that isn't 40 hex or an object that isn't a
+  commit (reader.mjs:29, :31). In practice that means a SHA-256 repository, so a rerun doesn't help.
+  The row now says "for example in a SHA-256 repository" and "Report to Sage".

+# Row 66: managed sessions run the unslop check on both harnesses
+
+Sage, 2026-10-20. Brief: `docs/plans/2026-10-11_managed-session-config.md`, section "Managed
+sessions run the unslop check on both harnesses", blob 21ae25a328d4. Issue #1559. Reviewers:
+Dewey and Filbert. Built in the worktree `/mnt/storage/scratch/sage-b66` (branch `sage/row66`)
+on base 5487ed39d.
+
+Candidate: see the commit line in the review request. `candidate-manifest.sha256` in this
+directory has the sha256 of each changed file at the candidate.
+
+## What changed
+
+**Wiring.** Both harness modules mount `tools/unslop-hook/lists.json`, `unslop-check.js` and
+the harness's own entry (pi `extension.ts`, Claude Code `claude-hook.js`) read-only at their
+own paths, and the bundle manifest lists the three in `sources` with their digests. Pi loads
+`extension.ts` as the second entry of `MOSAIC_EXTENSIONS`, after the gate extension. Claude
+Code's `settings.json` gains a Stop hook and a UserPromptSubmit hook, each
+`timeout -k 2 10 '<node>' '<dir>claude-hook.js' stop|prompt; exit 0`, hook timeout 20, no
+matcher. Neither can block a reply or a prompt.
+
+**claude-hook.js** (new). `stop` checks each assistant message with text since the turn's
+prompt and logs `checked` or `flagged`. `prompt` checks the last reply and, when it has tells,
+prints the extension's notice, word for word, as `additionalContext`, once per reply (it reads
+the log for an earlier `notice_injected` with the same entry id). A broken lists.json logs
+`broken_lists`; any other fault logs `hook_failed`; the exit is always 0.
+
+**The operator channel.** The runner sets `MOSAIC_UNSLOP_LOG` to `<run>/unslop.jsonl` after the
+module's variables, so a module can't point it elsewhere. After the landing turn and after each message turn it reads what the
+log gained (whole lines only, from an offset). The next RESULT it sends ends with a note. The
+whole note, both parts and the blank line before them, is at most 600 characters (r2):
+
+- `[unslop: N reply|replies of this session flagged since the last note: <details>. The session gets a correction notice on its next turn.]`
+- `[unslop: the check is broken, so this session's replies go unchecked: <reason>]`, once a run.
+
+That RESULT is what `mosaic talk` and `mosaic follow` print. A turn that sends no reply (an
+incoming RESULT, the landing turn) keeps its note for the next one. `note()` doesn't change
+state and `sent()` runs only after `message.send` succeeds, so a failed send keeps the note.
+`clip()` caps the body at 32000 characters plus its 33-character cut line before the note, so the
+sum is at most 32633, under the bus limit of 32768. The broken reason is cut at 300 where the
+runner takes it, from the log or from its own read failure, so the broken part is at most 371
+characters and the flagged part is cut to what is left.
+
+**Counts.** `unslopCounts(path)` reads the log after the session ended:
+`{checked, flagged, patterns: {<source>: n}, notices, broken}`. A missing log gives zeros.
+Findings now carry `source`, the entry's pattern id (`ms-unslop:7`), so `patterns` is per id.
+
+**The stack copy (r2).** `scripts/stack-copy.sh` `COPY_PATHS` gains `tools/unslop-hook`. Both
+modules join their files under `REPO`, and a session launched from a pinned copy has
+`REPO = copies/<sha>`. Without it every managed session from a copy past this row would fail at
+bundle build with ENOENT (Dewey P1, comment 29440).
+
+## Round 2
+
+Round 1 (candidate 8ec03b45a, manifest e68c6bce5ec4) got changes from Filbert (29439) and Dewey
+(29440). Round 2 carries:
+
+- F1 (both): a note with both parts wasn't bounded. A 300-character reason, a long flagged part
+  and a clipped answer came to 32934 (Filbert) or 33004 (Dewey), over 32768, and the broker
+  refused the send. `note()` now gives the flagged part only the room the broken part leaves, and
+  `fresh()` cuts every reason at 300, the runner's own read-failure reason included. Tests: the
+  runner test with an answer of 40000 characters, a 400-character `hook_failed` reason and 30
+  flagged replies (note ≤ 600, body ≤ 32768, cut line at 32000), and a unit check that both
+  parts come to exactly 600 and that a read failure on a 250-character path is cut.
+- F2 (Filbert; Dewey's M3): no test failed a send through `main()`. The new runner test has the
+  broker refuse the first RESULT. The note then rides the next RESULT. One correction to the
+  F1 consequence as written: the broker marks a received message delivered, so the refused
+  message isn't received again in that run. It stays unread and its sender gets no reply; the
+  turn doesn't rerun.
+- P1 (Dewey): `COPY_PATHS` gains `tools/unslop-hook`. The copy fixtures in
+  `stack-copy.test.mjs` and `pinned-copy.test.mjs` copy `tools/unslop-hook` too, and the
+  pinned-copy top-level list gains `tools`. A new `stack-copy.test.mjs` test makes a copy, loads
+  both harness modules from it, and checks that the adapter, the six unslop paths and the mounts
+  are under the copy and exist.
+- N1 (Filbert): the two session-test comments say `<dir>/unslop.jsonl`.
+- N2 (Filbert), doc-only follow-up: the brief's `<run>/session/unslop.jsonl` (:463) and "print
+  mode notifies nobody" (:477) are stale. The brief is Jason's text for this row; the deviation
+  below records the path.
+- Dewey's notes, no change: the Claude Code Stop timing (finding 3 below) gets a look in the
+  landing session; `patterns` keys per entry source, which is the brief's "per pattern".
+
+r2 mutants, each killed by its intended test (`mutants-r2.log`):
+
+| Mutant | Killed by |
+|---|---|
+| K1 the r1 `note()` cut | the clipped-answer runner test (the send is refused and it times out) and the unit check |
+| K2 `fresh()` doesn't cut the reason | the unit check |
+| K3 `sent()` before `message.send` | the refused-send runner test |
+| K4 `COPY_PATHS` without `tools/unslop-hook` | the copy test |
+
+## Ship list against the brief
+
+| Brief item | Where |
+|---|---|
+| A reply with a tell gets a correction notice on the next turn, both harnesses | `pi-session.test.mjs`, `claude-session.test.mjs`, row 66 four-turn tests: notices per request `[0, 1, 1, 2]`, notice text matched in the second request |
+| A clean reply gets none | same tests: turn 2 is clean and turn 3's request carries no new notice |
+| Broken lists.json fails closed: no clean verdict, operator told once, session alive | the row 66 broken-lists tests per harness: checked 0, flagged 0, first note broken, second note empty, the session answers both turns |
+| Counts readable after the session ends | `unslopCounts` on each session's log: `{checked: 4, flagged: 2, notices: 2, broken: null}`, patterns non-empty |
+| Interface 1 and the export list unchanged | no harness module export added or removed; the runner gains `unslopLog`, `unslopCounts`, `unslopNotes` |
+
+## Findings made while building
+
+1. **extension.ts read the wrong reply.** Pi 0.85.1 `getBranch()` returns entries root first
+   (`session-manager.js:958-967` reverses the leaf-to-root walk). `before_agent_start` took the
+   first assistant entry it met, which was the session's first reply, every turn. In the
+   four-turn test the old code gave notices `[0, 1, 2]` over three turns (turn 3 re-noticed
+   turn 1); walking from the end gives `[0, 1, 1]`. Fixed in `extension.ts`; this also affects
+   the fleet copy under `~/.mosaic/tools`, which I didn't touch.
+2. **claude-hook replies() merged replies.** Grouping by `message.id` across the transcript
+   merged two replies that shared an id (the test API answers `msg_mock` for all). It now groups
+   adjacent assistant lines only, keyed by the first line's uuid. Before the fix turn 4 got no
+   notice (`[0, 1, 1, 1]`).
+3. **Claude Code Stop timing.** On the first turn of a new session the transcript didn't yet
+   hold the reply when Stop ran, so the hook checked `last_assistant_message` with an empty
+   `entryId`. On resumed turns the reply was in the transcript. The verdict is the same either
+   way; only the entry id differs.
+4. The finding detail format is `banned word "delve" x1`.
+
+## Deviations
+
+- **The log path is `<run>/unslop.jsonl`, not the brief's `<run>/session/unslop.jsonl`.** A
+  thread run's session directory is the thread's store, and
+  `packages/cli/tests/thread-launch.test.mjs:179` pins that a thread run keeps no per-run
+  `session/`. My first build made `<run>/session` for the log and failed that test in the gate
+  (452/453). The brief's other line, "`unslop.jsonl` in the run directory", still holds, and each
+  run keeps its own log.
+
+- **`packages/seat/tests/sandbox.test.mjs`** isn't an owned file. Its pin
+  `binds(args).length === list.length - 1` broke because the modules now mount three more files.
+  It is now `- 4`, and the test asserts the three unslop read-only binds by name.
+- **`scripts/stack-copy.sh`** and the two copy tests aren't owned files. The copy change is P1
+  above. PB3 of the Part B window (`repin-partB-proof.md`) holds `scripts/stack-copy.sh` still
+  until B7, so this row lands after the Part B window has run.
+- `MOSAIC_EXTENSIONS` is set through the pi module's `env`, not in the runner.
+- `unslop-check.js` gained the `source` field on findings (needed for per-pattern counts).
+
+## Limits
+
+- The log is in the run directory, which the session can write. A session could forge or erase
+  its own counts. They are the session's report, not host evidence.
+- The pi extension's dedupe is in memory: after a restart, or when a turn's final message is
+  tool-only, the same earlier reply can get a second notice.
+- `hook_failed`, `skipped_broken` and `broken_lists` all count as broken for the operator note.
+- No blocking (Q84 option B), no list changes, no skill changes: out of scope by the brief.
+
+## Gate
+
+Recorded with the candidate in the review request: test-unslop-check, the harness, plugins,
+seat and cli suites, and every `scripts/test-*.sh`. At landing Sage runs one managed session per
+harness and attaches the notice, the correction and the counts.
+
+## Round 4
+
+Round 3 (2369c00e3 on sage/row66-r3, base c40d846cb, manifest 42e3876ca168) had approvals from
+Filbert (29770) and Dewey (29771). Since then rows 200, 199, 232, 233, 240 and 238 changed three
+of the 23 paths: `docs/TOOLS.md`, `scripts/stack-copy.sh` and
+`packages/cli/tests/stack-copy.test.mjs`. Round 4 is the two round 3 commits cherry-picked onto
+4ced5e63d (sage/row66-r4). Neither pick had a conflict, and the tree equals a hand merge of each
+path with `git merge-file`. No code changed: `git diff BASE TIP | git patch-id --stable` is
+6d085621fd35 for both rounds.
+
+- Row 232 added `copy --bundle` (`copy_bundle`). It builds the bundle with `copy_tree`, which
+  copies `COPY_PATHS`, so a bundle copy also carries `tools/unslop-hook`. No extra change needed.
+- The Part B hold under Deviations is void. Part B was superseded by the Q175 SSO work and will
+  not run, so nothing holds `scripts/stack-copy.sh`.
+- Review scope: the merge on the three moved paths and this section. The other 19 paths have the
+  same blobs as round 3.
+
+Rebased again on fefd54e13, after row 212 landed (ee7b2f137), as branch `sage/row66-r4b`, before the round 4
+request went out. 212 added `packages/library/src` to `COPY_PATHS` and a library line to the
+`stack-copy.test.mjs` file list. None of the four picks had a conflict. Every file's patch-id equals the 4ced5e63d
+build's except `scripts/stack-copy.sh`, where the only change is the hunk's context line
+(`packages/queue/src packages/library/src`). Row 66's two added lines are the same.
+
+Rebased again on 29ce1e360, after rows 195, 213 and 231 landed, as branch `sage/row66-r4c` (r4b stays at
+49ad61963). Two of row 66's paths moved: `adapters/README.md` and `docs/TOOLS.md`. TOOLS.md merged without a
+conflict. In adapters/README.md, row 213 rewrote the skill-cap paragraph, because `claude` now gets the prompt
+as a file. The merge keeps 213's paragraph whole and adds row 66's "The unslop check (row 66)" section after
+it. Row 66's old cap sentence is dropped, since it described the argument limit that 213 removed. Every other
+path has the same blob as on r4b. Row 213 also changed the harness and both adapter scripts, so all of row 66's
+harness tests run whole again on this base before the request.
+
+Rebased again on 7b9737953, after rows 245, 248 and 249 landed, as branch `sage/row66-r4d` (r4c stays at
+670b83f65). Only `docs/TOOLS.md` moved under row 66: row 245 rewrote the paragraph on what root reads in the
+host check. The cherry-pick had no conflict. `git patch-id --stable` of row 66's whole diff is 508bb684eade on
+both bases, and so is each file's own patch-id, TOOLS.md included. So row 66's hunks are byte-identical and only
+their context moved. The one test that names TOOLS.md, `packages/cli/tests/stack-release.test.mjs`, uses it in a
+message string and is in the singles list.
+
+Rebased on a36523713 after row 197 landed (mos-1186 item 4), as branch `sage/row66-r5` (r4d stays at
+82c830779). Row 197 also touched `packages/harness/tests/claude-session.test.mjs` and `pi-session.test.mjs`.
+The cherry-pick had no conflict. The range-diff shows commit 1 differing only in one hunk header of
+pi-session.test.mjs, where git now names the context line. Commits 2-7 are `=`. `git patch-id --stable` is
+0049d05fb585 for the whole diff and d67275ac4251 without `agents/` on both bases. Correction: the r4d note
+above gives 508bb684eade for the whole diff. That number came from e25f76f54 before the 7b9737953 rebase. The
+whole-diff number on r4d is 0049d05fb585. The harness suite runs whole again on this base before landing.
+
+Correction (Filbert round 4 N2, comment 30086): the r4c paragraph says "Row 66's old cap sentence is
+dropped." That's wrong. In round 3's diff the 64 KiB cap sentence is unchanged context, so row 66 never
+wrote it. Row 213 replaced it, and none of row 66's lines were dropped. The landing sessions are in
+LANDING-SESSION.md.

+## Claude Code, run r4ab24630d323 (18:48Z)
+
+The chief and cto were bound, and the coder was launched through `launcher.fromSession` on claude-code,
+model claude-sonnet-5-5. The launch bundle names `tools/unslop-hook/claude-hook.js`, `unslop-check.js`
+and `lists.json`.
+
+- Turn 1. cto asked for one sentence with four banned words. The RESULT body `mosaic talk` would print
+  ends with the operator note:
+  `[unslop: 1 reply of this session flagged since the last note: banned word "additionally" x1; banned word "crucial" x1; banned word "testament" x1; banned word "vibrant" x1. The session gets a correction notice on its next turn.]`
+- Turn 2. `unslop.jsonl` logs `notice_injected` for that turn. The coder's transcript has the notice as
+  UserPromptSubmit hook additional context in the API request:
+  `UNSLOP NOTICE (mechanical style check, not the user speaking): your previous reply contained violations of the fleet writing standard (SYSTEM.md / ms-unslop): ...`.
+  cto asked the coder to quote it. The coder answered "I can't answer that one, and I won't quote

+# Your books in Mosaic: a setup sheet
+
+This sheet is for you, Melanie. You keep writing in Obsidian the way you do now. Mosaic reads your
+books repo after obsidian-git pushes it to git.mosaicstack.dev. It changes nothing on your machine and
+commits nothing to your repo.
+
+## What the agents read
+
+The agents read your books repo as you last pushed it. A push reaches them in about a minute.
+
+They read notes, the `.md` files, inside your book folders. They don't read:
+- notes at the top of the repo, outside any book folder
+- `.canvas` and `.base` files, even inside a book folder
+- images and other attachments
+- anything in your other repos under `~/src`
+
+They can't write to your repo at all. That covers canon, the playground and everything else.
+
+Which folders are book folders, and which hold characters, places, research, your tracker or chapter
+summaries, is set in one place. It is the `projects` entry of your business file in Mosaic. Jason
+edits it by hand, and the agents can't change it. He will ask you to confirm it before the agents start.
+
+## Your playground
+
+A folder named in the `playground` list of that entry is your playground. Each playground folder sits
+inside one book folder, so one per book works well, for example `<book>/playground/`. You choose the
+names and tell Jason. Until you have one, every note in a book folder is canon.
+
+What the playground means for the agents:
+- They search canon unless they ask for the playground on purpose.
+- An agent may quote a playground note in an idea or a question. It may not use one to back a fact,
+  a finding or a correction. Mosaic refuses that reply before you see it.
+- Only the folder decides. A tag or a property can't make a note playground or canon.
+
+### Colour the playground in your graph
+
+This is a setting of your own vault. It changes nothing for the agents.
+
+1. Open the graph view and open its settings panel.
+2. Under Groups, choose New group.
+3. In the query box, type the playground's path with `path:`. Your vault is `~/src`, so the path
+   starts with your books repo folder: `path:"<books repo folder>/<book>/<playground folder>"`.
+4. Pick a colour.
+
+Add one group per playground folder.
+
+## Two things you might not expect
+
+### Moving a note into a book folder makes it canon
+
+The folder decides, so a move changes what the agents may do with a note. Once you move a note out of
+the playground into a book folder and push, it is canon. The agents may then cite it as fact. A note
+that isn't settled yet belongs in the playground. Any note in a book folder outside the playground is
+canon, rough drafts included.
+
+### A short link can point somewhere else for the agents
+
+Obsidian looks up a short link like `[[Mara]]` across your whole vault, `~/src`. The agents see only
+your books repo. Say a note called `Mara` exists in your books repo and also in another of your repos.
+Obsidian and the agents can then open different notes for the same link, and the agents can't tell.
+If the name exists only in the other repo, the link leads nowhere for the agents.
+
+A link with the full path from the top of your vault reaches the same note in both:
+
+```
+[[<books repo folder>/<book>/<characters folder>/Mara]]
+```
+
+Obsidian can write new links this way. In Settings, open Files and links and set New link format to
+Absolute path in vault.
+
+## Lists of links in properties
+
+The agents read the links in two properties, `appears_in` and `relationships`. Put quotes around each
+link in the list:
+
+```yaml
+appears_in: ["[[A]]", "[[B]]"]
+```
+
+One link per line works too:
+
+```yaml
+appears_in:
+  - "[[A]]"
+  - "[[B]]"
+```
+
+Obsidian's property editor adds the quotes for you. If you type the list by hand, don't leave them out:
+
+```yaml
+appears_in: [[[A]], [[B]]]
+```
+
+The agents' reader can't read that form. It then ignores every property of that note and lists the
+note as a problem in Mosaic's status. It still finds the note by its path, its name and its text. A
+value written without `[[ ]]` counts as a plain name, not a link.
+
+## What changes for Bean and Chet
+
+They keep their names and personalities. How they answer changes.
+
+In Hermes they answer in free text and may write story text when you ask. In Mosaic every reply is a
+short list of items. Each item is an idea, a question, a finding or a fact. Each one quotes a line
+from your repo or from a web page the agent read for you.
+
+They don't write passages. If you ask for prose, you get a question or an idea instead.
+
+A reply holds at most 10 items and at most 1,200 characters of item text in all. It has at most 5
+ideas of up to 200 characters each. A question, finding or fact runs up to 300 characters. You or
+Jason can ask for lower limits. When an agent can't back an answer with a quote, you see "No cited
+answer" instead.
+
+Each book world stays separate. One item can't mix quotes from two worlds.
+
+You talk to them in the Console. Hermes keeps running until you have moved over, and stopping it is
+your choice.
+
+Five more helpers can join them: ideas, research, proofreader, fact-checker and continuity. You
+choose which ones to start with, and you can add one later.
+
+## What Jason will ask you
+
+He will ask you to confirm your book folders and type folders, which books share a world, the name of
+each playground folder, and which helpers to start with and when.

+# Survey run sheet for the library host
+
+This sheet is for whoever runs `mosaic library survey` on `<host>`, 10.1.1.54, under design 10 step
+7. The survey reads one commit of a git repo and prints names and counts. It never prints note text,
+property values, file names or link targets. Jason fills in the mapping for Melanie's books repo
+from its output and her answers.
+
+Out of scope: sending anything to Melanie. Design 10 step 7 makes that Jason's call.
+
+## Before you start
+
+- Jason's go for step 7. Step 4, the bot token in the `library-gitea` slot, comes first.
+- You run as `mosaic` with `sudo -u mosaic -H` from `localadmin`. `mosaic` has no login shell.
+- The stack copy from step 2 is in place at `/srv/mosaic/.local/share/mosaic-stack/copies/<id>`.
+  `<id>` is the full commit id in Jason's go. It must hold row 231, which escapes control and bidi
+  characters in folder names. In a canonical checkout, `git merge-base --is-ancestor 29ce1e360 <id>`
+  exits 0 when it does.
+- `<node dir>`, the directory that holds `node`. It is the directory of the `--node` path given to
+  `case2-unit.sh` in step 2c. `scripts/mosaic` runs `node` from `PATH`.
+- `<repo>`, an absolute path. See the next section.
+
+## The repo to survey
+
+The survey reads a local repo. It doesn't fetch. `<repo>` must:
+- be the repo's top folder, or a bare repo's own folder. A folder inside a repo refuses, because the
+  survey stops git from looking above the path's parent.
+- belong to `mosaic`. The survey gives git no global config, so a `safe.directory` entry can't
+  admit a repo another user owns.
+- have a `HEAD` that names a commit. The survey reads `HEAD` and has no flag for another ref.
+
+`<repo>` is the bus's bare mirror at `<dataRoot>/projects/<business>/<project>`, which C2-04 (row 215)
+creates and C2-03a (row 222) fetches into. It is the only copy of her repo on the host (design 2.1), and
+`mosaic` owns it. Survey it after the first `library.sync` succeeds. The mirror's `HEAD` points at
+`refs/heads/served` (C2-03a brief), so the survey reads the commit the agents are served.
+
+Don't survey anything else. A hand clone with the bot token would put the token where design 7.2 keeps
+it out, and the mirror's refs belong to the bus. If `HEAD` names no commit, stop and report to Sage.
+
+## Steps
+
+1. `ssh [email protected]`.
+2. Check which `node` runs. `PATH` ends in `/usr/bin:/bin`, so a wrong `<node dir>` would quietly run
+   another `node`:
+
+   ```sh
+   cd /
+   sudo -u mosaic -H env PATH="<node dir>:/usr/bin:/bin" sh -c 'command -v node; node --version'
+   ```
+
+   The first line must be `<node dir>/node`. If it isn't, fix `<node dir>` before going on.
+3. Run the survey without a mapping:
+
+   ```sh
+   cd /
+   sudo -u mosaic -H env PATH="<node dir>:/usr/bin:/bin" \
+     /srv/mosaic/.local/share/mosaic-stack/copies/<id>/scripts/mosaic library survey <repo>
+   echo "exit $?"
+   ```
+
+4. On exit 0, give the output to Jason. On any other exit, see "Refusals" below.
+5. When Jason has a draft mapping, run it again with `--mapping`. The file holds the library entry
+   alone, `{"kind": "library", "remote": ..., "branch": ..., ...}`, without the business file or the
+   `"projects"` wrapper around it. `remote` and `branch` are required even though the survey doesn't
+   fetch. `mosaic` must be able to read the file. Set `vaultPrefix` to her books repo's folder name
+   in her vault. Without it, a link with the full path from the top of her vault resolves to nothing,
+   and the setup sheet tells her to write links that way.
+
+   ```sh
+   sudo -u mosaic -H env PATH="<node dir>:/usr/bin:/bin" \
+     /srv/mosaic/.local/share/mosaic-stack/copies/<id>/scripts/mosaic library survey <repo> --mapping <file>
+   echo "exit $?"
+   ```
+
+The usage line is `mosaic library survey <repo> [--mapping <file>]`. `--mapping <file>` is the only
+flag, and it may appear once. `--mapping=<file>` and every other flag refuse.
+
+## What the output holds
+
+Plain text on stdout, one line per item:
+
+| Line | What it holds |
+|---|---|
+| `commit <id>` | the 40-hex commit `HEAD` names |
+| `entries <n>` | every entry in that commit's tree |
+| `folders (direct children: md canvas base other)` | then one line per folder that holds a file directly: its path as a JSON string and four counts. `(root)` is the repo's top |
+| `markdown <n> files, <n> read, ...` | `.md` files, how many were read, how many have no front matter, how many have front matter the reader can't fully parse |
+| `front matter key sets` | then `<count> [<keys>]` per set of property names. A name that isn't a short identifier prints as `(other key)` |
+| `body links plain .., label .., heading .., embed .., self .., markdown ..; attachment ..` | link forms in note bodies, and embeds of a target with an extension other than `.md` |
+| `field appears_in wikilink .., name ..` | values written as links and as plain names. A `relationships` line follows |
+
+With `--mapping` three lines follow:
+
+| Line | What it holds |
+|---|---|
+| `scopes canon .., playground .., unmapped ..; indexed ..` | tree entries per scope, and notes indexed |
+| `resolved root .., vault-prefix .., relative .., shortest .., unresolved ..` | links per resolver step. `unresolved` is the R4 count |
+| `problems R1 .., ..., R7 ..` | problems per rule |
+
+Folder paths and short property names are the only words from her repo in the output. In a folder
+name, tab, newline, carriage return, backspace and form feed print as `\t`, `\n`, `\r`, `\b` and `\f`.
+Any other control or bidi character prints as `\uXXXX`.
+
+## Refusals
+
+A refusal prints nothing on stdout and one line on stderr. The survey checks the mapping before the
+repo, so a bad mapping gives exit 3 even when the repo path is wrong too.
+
+| Exit | stderr | Cause | What to do |
+|---|---|---|---|
+| 4 | `library survey: usage: mosaic library survey <repo> [--mapping <file>]` | no repo, two repos, an unknown flag, `--mapping` without a file or twice | Fix the command |
+| 3 | `library survey: library-mapping-invalid: <file> is not a readable JSON file` | missing, unreadable by `mosaic`, or not JSON | Fix the file or its mode |
+| 3 | `library survey: library-mapping-invalid: <file> <reason>` | the entry breaks the schema. The reason names the key | Give it to Jason for the draft |
+| 3 | `library survey: library-playground-outside-book: <file> universes.<u>.playground "<prefix>" is not inside one of its books` | a playground prefix outside its universe's books | Give it to Jason for the draft |
+| 2 | `library survey: library-git: <repo> is not a directory` | wrong path | Check `<repo>` |
+| 2 | `library survey: library-git: repository has no readable HEAD commit (project-git)` | not a repo, a folder inside one, another owner, no commits, a `HEAD` with no commit, or no `git` on `PATH` | Check each. If `<repo>` is the bus mirror, stop and report to Sage |
+| 2 | `library survey: library-git: <other reason>`, such as `tree listing refused (project-git)` | git failed or ran past 100 seconds | Report to Sage |
+| 2 | `library survey: library-commit: <reason>` | `HEAD` names something the reader can't take as a commit, for example in a SHA-256 repository | Report to Sage |
+| 127 | a line ending `exec: node: not found` | `node` isn't in `<node dir>` | Fix `<node dir>` |
+| other | a Node stack trace | a fault in the survey | Stop and report the exit code to Sage |
+
+A refusal is the answer, not an obstacle. Don't run as another user, change modes on her repo or edit
+its refs to get past one.

+
+## Machine grant row b follow-up: the held stubs end with their test
+
+The row 197 r8 D5 proof stopped on a leftover process on 2026-10-21. In
+`packages/bus/tests/grant-executor.test.mjs`, the `add` stub waits for `release` when `hold-add`
+is set. G23 ("a revoke during install") and G13 write `release`, finish, and `t.after` removes the
+test dir. The stub polls every 50 ms, so it usually misses `release` and then loops forever on a
+dir that is gone. Four runs of the file on Sage's slot left 7 stubs, every run 37/0.
+
+Build: each hold loop in that file, `hold-add` and `hold-remove`, also stops when `$D` no longer
+exists. The test file is the only change. Nothing under `src` changes.
+
+Gate: Webby approves the commit. On Sage's gate the whole file passes three times in a row with no
+stub left, checked by pgrep on the run's TMPDIR, and the bus suite is green. A mutant that drops the
+dir check from `hold-add` leaves a stub behind.
+
+## Machine grant row b follow-up: the undo can't prove the remote add has ended
+
+Mos asked this in mos-1166. Gizmoduck answered in gizmoduck-0137 and gizmoduck-0139, and Duckworth
+checked the answer in duckworth-0091. Line numbers are at 6d5545d44.
+
+An abort during install SIGKILLs the local ssh process group (host-run.mjs:136). A timeout does the
+same (host-run.mjs:131-134). sshd gives a non-pty command no SIGHUP when the client dies, so the
+remote `add` can keep running. The undo runs `remove <user> <tag>` once (broker.mjs:1017). If the add
+writes its line after that, the remove has already exited 0 and `hostLineLeft` stays unset (:1019).
+Then hosts.status shows the host clean (:1396), reconcile skips a grant that already ended
+(:1042), and nothing prompts a sweep. hosts.remove's host-line-left check (:1362) passes, and once
+the record is gone a sweep refuses host-unknown (:1350), so no verb reaches the line. The line
+authorizes a key nobody holds, under the installer's restrict prefix. No test covers this case. G24
+seeds its failed grant with `hostLineLeft` already set.
+
+Build:
+- In `#runHostGrant`, mark install done right after `await install(...)` returns. In the catch, when
+  install started and never returned, record `hostLineLeft: tag` whatever the remove's exit was. The
+  rule keys on install not returning. It covers an abort, a timeout and a dropped connection, and
+  doesn't depend on `signal.aborted`. The message names `mosaic hosts sweep <host>`.
+- An add that exits nonzero on the host also records the hint. That hint is false but harmless,
+  since a sweep that doesn't list the tag drops it (G24, "a left tag no longer on the host").
+- Fix the comment at grant-executor.test.mjs:432, which says a killed session's add exits.
+- Row a's enroll add: check it for the same race, then fix it or record in BUILD.md why it can't
+  happen.
+- Owner Gizmoduck. Reviewer Duckworth.
+
+Tests: one abort case and one timeout case. Each uses a held stub add that writes after the remove
+and exits 0. Each asserts `hostLineLeft` on grant.failed and in hosts.status, that hosts.remove
+refuses host-line-left before the sweep, that the sweep removes the line, and that hosts.remove then
+succeeds. A mutant that drops the new catch branch fails a test.
+
+Gate: Duckworth approves the manifest. On Sage's gate the bus suite and the whole touched test files
+are green, and the mutant is killed.

+# Brief: Console inbox Approve and Deny for grant requests (Vikunja #435, J2)
+
+Sage, 2026-10-21, for Mos's order mos-1193 (Jason asked at 18:35Z to test J2 sooner). Vikunja #435, parent
+#424, DECISIONS Q188. Owner Gander, reviewer Webby, gate owner Sage. Chained on row 196's candidate (Q177):
+the design starts now on Gander's row 196 build. The code lands after row 196 lands and rebases onto that
+landing. Design first. The first deliverable is `agents/gander/work/queue-ROW/DESIGN.md`.
+
+## What Jason asked for
+
+Q188, as #435 records it: the chief surfaces each grant request to Jason's inbox in the WebUI, and he clicks
+Approve or Deny. It needs the Console to know who is signed in (Q175 SSO, #412). Until then Approve is
+`mosaic decide`.
+
+## Where things stand
+
+- The Console inbox shows decisions and prints `mosaic decide <id> <key>` for each choice
+  (`packages/webui/README.md`, Inbox section). It takes no human writes: without `--send` every method
+  other than GET and HEAD answers 403 `read-only`, and the live unit runs without it (row 189).
+- Q175 phase 1 (row 192, landed 4429a104f) builds the Console's own OIDC session. It is live only after the
+  phase 2 re-pin window turns on `--sso`. Under `--sso` every request other than `GET /healthz` needs a
+  verified session.
+- Row 196 (Gander, Duckworth) settles how the bus tells the human's own call from a same-uid process. A
+  Console write that resolves a decision must go through whatever row 196 lands, not around it.
+- The PRD doesn't allow this yet. REQ-DEC-3 says a human resolution comes only from a `mosaic` CLI session
+  started outside any agent run. Jason approved REQ-WEB-2 and the REQ-DEC-3 amendment in decision
+  00ed58e2 (Vikunja 19/266), and the PRD holds the id REQ-WEB-2 for it (1.8, "held for the Console decide
+  buttons amendment"). That amendment must land before this row's code does. PRD wording goes to Mos first,
+  then Jason. This row doesn't edit the PRD.
+
+## What the design must settle
+
+1. Which decisions get the buttons. #435 names grant requests (Q188). Say whether the first cut covers only
+   those or every open decision under REQ-WEB-2, and why.
+2. The identity. The resolving human is the verified OIDC subject from the Console session (row 192), mapped to
+   an authorized human the bus knows. Nothing comes from a proxy header or a shared secret (Q175). A request
+   from an agent session or a seat credential is refused.
+3. The write path. How the Console's POST reaches the bus's decide, using row 196's human boundary, and what
+   the decision event records: `via=console` and the subject.
+4. The guards: CSRF, a confirmation step, a decision that is no longer open, a stale option key, a double
+   click, and the read-only and `--no-send` modes. State each refusal's status code and message.
+5. Without `--sso` the buttons don't exist or are disabled. Say which, and what the inbox shows instead
+   (today's `mosaic decide` line).
+6. Tests on stand-ins only: a fake OIDC provider and the test bus, as row 192's tests do.
+
+## Boundaries
+
+- No change to who can reach the Console from outside. That stays Jason's.
+- No test touches `~/.mosaic-dev`, `~/.config/mosaic-dev`, the live units or a slot file. No request to the
+  live 127.0.0.1:7332 or 7333, mosaic.woltje.com or auth.diversecanvas.com.
+- Turning the buttons on live needs the phase 2 window (`--sso`) and then a re-pin whose tree has this row.
+  Both are windows with Jason. This row ships the code and the tests.
+
+## Gate
+
+Webby approves DESIGN.md, then the manifest. The webui, bus and cli suites and every `scripts/test-*.sh` are
+green on Sage's gate, and the mutants named in DESIGN.md are killed. The PRD amendment for REQ-WEB-2 has
+landed first.

+# Brief: K12 reads cgroup.events after cgroup.kill under load
+
+Sage, 2026-10-21, for Mos's ruling mos-1182 item 3. Vikunja #450. Gate owner Sage. Owner and reviewer are
+named when the row is briefed. Base: refactor at the brief commit. The row comes after row 197, unless
+proof 5 fails on K12 again (mos-1182 item 4). Then it goes ahead of 197, and 197's candidates rebase on it.
+
+## Why
+
+`packages/conversation/tests/cohort.test.mjs` K12 (line 268) force-stops a member that forks in a loop.
+Then it asks the shim for `events` and asserts `ev.populated === 0` (line 292). It never checks `ev.ok`.
+`events()` in `packages/conversation/src/shim.mjs:83-96` returns `{ ok: false, unavailable }` when
+`engine/cgroup.events` can't be read or has no `populated` field. Under load the test then fails on
+`undefined !== 0` and never says why.
+
+This has happened twice:
+
+- BUILD-LOG.md:4092: conversation went 181/1 at a load of about 12 while mutants ran, and 182/0 alone.
+- Row 197 proof 4, wave pair1-b, 2026-10-21T16:04Z: 147/1 with two conversation suites running at once.
+  The log is `/mnt/storage/scratch/sage-r197p4/proof-run/pair1-b/out/pkg-conversation.log`.
+
+## Steps, in order
+
+1. Make the failure name its cause. The K12 assertion prints `ev` (with `ok` and `unavailable`) when it
+   fails. Commit this first, on its own.
+2. Find why the file is unreadable or lacks `populated` after `cgroup.kill` under load, and fix that at the
+   source. Use the shim, the cohort controller or the test's setup and teardown, whichever the evidence points
+   to. Record the evidence in `agents/OWNER/work/queue-ROW/BUILD.md`.
+3. Do not loosen the assertion. Do not treat `unavailable` as empty, or `populated` as 0 when it can't be
+   read. Retrying a read that is still in progress is allowed only if step 2 shows a race in the read
+   itself, and the retry has a bound and a test.
+
+## Files owned
+
+`packages/conversation/src/shim.mjs`, `packages/conversation/src/cohort.mjs` if step 2 needs it, and
+`packages/conversation/tests/cohort.test.mjs`. Nothing in row 197's 37 paths.
+
+## Tests
+
+- K12 still asserts `populated` 0 and an empty member list.
+- A new case shows `events` returning `unavailable` with its reason, and that the controller treats that as
+  unavailable, not as empty.
+- The conversation suite passes whole three times in a row, and once while a second conversation suite
+  runs at the same time. That is the load that broke it in proof 4.
+
+## Gate

+Sage, 2026-10-21, for Mos's ruling mos-1185 item 2. Vikunja #453. Gate owner Sage. Owner and reviewer are
+named when the row is briefed. Base: refactor at the brief commit. The row comes after row 197, unless
+proof 6 fails on a test outside 197's paths in a pair wave (mos-1185 item 4). Then this row and row 250 go
+ahead of 197, and 197's candidates rebase on them. The pattern is row 250's
+(`docs/plans/2026-10-21_k12-cohort-events.md`).
+
+## Why
+
+`packages/bus/tests/host-run.test.mjs:453`, "T27: ssh-add -t drops the key from an agent the test keeps
+alive", starts its own `ssh-agent -D -a SOCK`, calls `addKey(sock, key, 1)` from
+`packages/bus/src/host-run.mjs:87`, and asserts that `ssh-add -l` lists the key (line 469). Then it sleeps
+2.5 s and asserts the key is gone.
+
+Row 197 proof 5, wave pair2-b, 2026-10-21T17:07Z: the first assertion got "The agent has no identities."
+31.9 ms into the test. The bus suite went 289/1. The log is
+`/mnt/storage/scratch/sage-r197p5/proof-run/pair2-b/out/pkg-bus.log`. The same test passed in solo-b and
+pair1-b of that run.
+
+The cause is not known yet. One lead, unverified (Mos, mos-1185): ssh-agent may count lifetimes in whole
+seconds of CLOCK_MONOTONIC, so a key added just before a monotonic second boundary expires within
+milliseconds. A test aligned to wall-clock seconds did not test that idea.
+
+Sage checked the lead on dragon-lin, OpenSSH 10.5p1, 2026-10-21T17:19Z (`/mnt/storage/scratch/sage-r64/t27-mono.mjs`,
+outside any gate). It made 80 adds of `ssh-add -t 1`, each at a chosen fraction of a CLOCK_MONOTONIC second
+(`process.hrtime`), and listed at once. 8 of 80 missed. Every miss was an add made at 0.9947-0.9973 of a
+monotonic second that finished at 0.998-0.0008. No add earlier in the second missed. So a 1-second lifetime
+can end within milliseconds of the add. Step 2 still confirms this against the T27 failure itself.
+
+## Steps, in order
+
+1. Make the failure name its cause. When the first assertion fails, print the time from addKey's start
+   to its resolve and to the `ssh-add -l` call, the monotonic clock (`process.hrtime.bigint()` or
+   `/proc/uptime`) at each, and the agent's state (alive, socket present). Commit this first, on its own.
+2. Find the cause and fix it at the source: the test's lifetime choice, `addKey`, or how the agent is
+   started. Record the evidence in `agents/OWNER/work/queue-ROW/BUILD.md`.
+3. Do not loosen the check. The test still proves the key is listed after the add and gone after its
+   lifetime. A longer lifetime is a fix only if step 2 shows whole-second rounding is the cause, and then
+   the sleep grows with it.
+
+## Files owned
+
+`packages/bus/tests/host-run.test.mjs`, and `packages/bus/src/host-run.mjs` only if step 2 points there.
+Nothing in row 197's 37 paths.

+## Tests
+
+- T27 still asserts the key is listed, then gone.

+The reviewer approves on the row, naming the candidate manifest. The bus suite passes whole on a gate

+# Gate lanes
+
+This tooling is for Sage's granted test gates on dragon-lin. It does not grant
+itself a slot. A grant reference is an audit field, not an authentication token.
+Until Sage adopts these lanes, the existing shared-slot procedure still applies.
+
+Ask Sage with the lane, candidate SHA and exact command. Get a separate grant
+for image preparation, suites, and the whole-slot paired proof. New state is
+`/mnt/storage/scratch/mosaic-gate-lanes`. Old slot files are untouched.
+
+Invoke the entry from the builder or canonical repository. The --checkout target
+must be a separate clean scratch clone containing identical tooling source:
+
+```bash
+scripts/testing/gate-lane.sh run --lane a --candidate FULL_SHA \
+  --checkout /mnt/storage/scratch/ROW-RUN/wt \
+  --out /mnt/storage/scratch/ROW-RUN/out --grant SAGE_MESSAGE_ID \
+  --image-receipt /mnt/storage/scratch/PREP/image-receipt.json
+```
+
+Each run creates a private root like `/mnt/storage/scratch/ga-ABCDEF` (30 bytes).
+An explicit `--temp-root` must already be private, outside `/tmp`, and no longer
+than 30 UTF-8 bytes after resolving symlinks. The sandbox's own `/tmp` and HOME
+are unchanged. Host HOME stays real. A listener covering loopback port 9, an
+unsafe privileged-port threshold or unreadable host inventory refuses startup.
+
+Lane a leases ports 61000..61127, lane b 61128..61255. Refuse any band overlapping
+the host's current ephemeral range or a live listener. Port-0 fixtures with a
+held server keep using port 0. Never replace the literal dead Board :9 URLs.
+Two Node test files run per lane, including nested shell-suite Node runners.
+
+```bash
+scripts/testing/gate-lane.sh status
+scripts/testing/gate-lane.sh recover --run-id RUN_NONCE --grant SAGE_MESSAGE_ID
+```
+
+Status reports each lane, the image lock, unfinished receipts and unmanaged
+test/landing/build processes as LEGACY BUSY. It prints no command lines or
+environment values. A dead owner with an unfinished receipt is quarantined even
+when flock is free. Recovery takes both lanes and the exclusive image lock.
+Unknown process-group, scope or Docker ownership refuses recovery. Do not remove
+lock files, old receipts, or another run's resources to clear a refusal.
+
+An image receipt records exact COPY input hashes/modes, image ID, release tag,
+base digest and platform. Both concurrent candidates must match those files and
+that same image ID. Rebuilding identical files is not equivalent. Warm gates
+refuse implicit Docker builds/pulls and recheck the ID at each step and the end.
+External same-uid commands can ignore these locks. Sage must exclude other
+builders; this is test coordination, not a security boundary against that uid.
+
+Only under an explicit image-build grant:
+
+```bash
+scripts/testing/gate-lane.sh prepare-image --lane a --candidate FULL_SHA \
+  --checkout /mnt/storage/scratch/ROW-PREP/wt \
+  --out /mnt/storage/scratch/ROW-PREP/out --grant SAGE_MESSAGE_ID
+```
+
+Preparation holds both lanes and the exclusive image lock. Its build log,
+receipt, count and wall time are separate from warm gate timings. The current
+Containerfile uses a mutable FROM tag and apt indexes. A missing base digest
+refuses provenance publication. No credential file is copied or printed.
+
+Run records are immutable JSON files published by link after fsync. Every step
+has a log, UTC/monotonic times, exit code, pass/fail/skip counts and log hash.
+The first failed step stops the gate. Cleanup touches only exact project labels,
+recorded process identities and fixture paths. A process leak fails the gate
+even when cleanup succeeds. Failed logs and temp roots remain for diagnosis.
+A cleanup failure leaves the lane quarantined. GATE_PASSED requires all steps
+and cleanup. Required prerequisite skips fail the run; optional skips remain
+visible and require acceptance review.
+
+Home metadata is evidence only. Assert only on entries attributable to this
+run's nonce or fixture paths. Other sessions normally change ~/.claude, ~/.pi
+and ~/.cache, so there is no global unchanged-home assertion.
+
+The row 197 acceptance packet is `agents/herb/work/queue-197/`: two candidate
+solo baselines followed by three overlapping pairs, lane assignment swapped in
+pair two. Keep later paired results after adoption. Six green gates establish
+the initial acceptance bar, not a reliable estimate of rare flakes.
+
+The preflight unit fixture uses the canonical checkout's existing node_modules
+at `/mnt/storage/src/mosaic-stack/node_modules` through the required plain
+symlink. It does not install dependencies. Unit run roots use the `gt-` prefix;
+real lane roots use `ga-` or `gb-`. Resource helper tests inside a lane lease only
+that lane's band through MOSAIC_GATE_STATE, including their child test files.
+The exhaustion probe temporarily narrows its process-local band to a port it
+already leased, so it never reserves the whole shared band.
+
+`closed` call-site options are accepted for compatibility; every dynamic lease
+reserves an unbound endpoint. Listener fixtures decide when to bind and close.
+Fixture child caches put TMPDIR under `tmp/` next to `jiti/` and `cache/`.
+
+Outside a lane, the resource helper file uses lane a with the shared default
+state `/mnt/storage/scratch/mosaic-gate-lanes`. It leaves stable lock files in
+place. A single-file run therefore respects a live lane-a gate's closed leases.
+Its unrelated-session probe bounds both polling children at five seconds.
