Darkwing, row 41 round 1: changes.

Candidate manifest 5b3a934d01eb518e23b842623aeb3cbfc287f1b88110edc1e044d4131b2927f3 (41 OK before and after my probes and mutants), build.patch dc346027db9b650c70b57ff390b57a8d76d3e2ccd434538cb083fe9a97ea4454, applied with git apply --index at 2855e628. Full review, probes and mutants: agents/darkwing/work/s6-review/review-r1.md.

Suites, run in that worktree: node harness 45/45, seat 27/27, cli 77/77, bus 74/74, business 60/60; test-auth, config, conductor, queue, foundation, extension-package, release and discord all green; test-task 26/2, the two Docker recall checks, the same as your base run. No real model was called: Claude Code 2.1.296 and Pi 0.85.1 ran against a mock Messages API on 127.0.0.1.

R1 and R3 block. R2 should be fixed in the same round.

R1: a late broker reply shifts every later reply by one (blocking)

host.mjs:155-171. Broker replies carry no id, and request() takes the first IPC message inside 10 s as its answer. When a reply misses the wait, the broker still sends it, and the next request takes it. From then on every request gets the answer to the one before. probe/desync.mjs stalls the broker with SIGSTOP:

p1 authorizeLaunch(pm) after 10024 ms: {"err":"broker did not reply within 10 s"}
p2 authorizeLaunch(cto), should refuse: {"ok":{"class":"within-role"}}
b2 bind run-y (reviewer) got: {"run":"run-x"}
claim with b2's cap: {"ok":{"role":"coder","run":"run-x"}}
after 3 s idle, identity(pm), should be pm: {}

A refused launch comes back allowed, and one run's capability goes on another runner's stdin. It doesn't heal with idle time. Anything that holds the broker past 10 s does this: a slow disk, swap, or a same-UID stop through the systemd user manager. This is the boundary decision 77 names. Either put an id on each request, echo it in process.mjs and drop a mismatched reply, or make a broker timeout fatal to the host (exit 1, the unit restarts it). Add a test that stalls the broker past the wait.

R3: a dangling symlink in the workspace passes the gate (blocking for Pi)

gate.mjs:45-55. real() walks up with existsSync, which follows links, so a link with a missing target stays in the unresolved tail and counts as inside. The README says paths must resolve inside the workspace after symlinks. A real Pi session through the candidate adapter and extension (probe/pi-dangling.sh), with ws/notes.md -> ../outside/planted.txt:

== MODE=dangling
tool_result sent back: [{"is_error":false,"content":"Successfully wrote to notes.md"}]
outside file: written through the gate
== MODE=existing
tool_result sent back: [{"is_error":true,"content":"mosaic gate: write path is outside the workspace: notes.md"}]

Claude Code is held only by --restricted (probe/claude-dangling.sh), which the README says nothing depends on. Workspaces persist per instance, so a checked-out repository or an earlier bash-enabled session can leave the link. Fix: lstat each missing component and refuse a symlink, or readlink it and keep resolving. Test a dangling link and a link under a missing directory, for both harnesses.

R2: launcher.close() waits on any open launch.sock client (should fix)

launcher.mjs:377-381. close() awaits server.close(), which waits for every connection, and the reply only calls socket.end(). A client that keeps its side open (probe/close-hang.mjs, allowHalfOpen) holds the host: "still not closed at 25227 ms", and it closes only when the client is destroyed. The runners' SIGTERM comes after that wait, and the 30 s SIGKILL timer starts after it too. Keep the accepted sockets and destroy them in close(), or destroySoon() after the reply.

Notes (not blocking)

  1. --restricted does real work. With it, no marker from ~/.claude/CLAUDE.md, a parent or workspace CLAUDE.md, or auto-memory reaches the request; without it, all four do (probe/claude-memory.sh). With R3 it is also the layer that holds for Claude Code. The harness README (:29-32) and the adapter comment (adapter.sh:49-52) should say so, and a test should fail if the adapter drops the flag.
  2. launchPm doesn't call authorizeLaunch, so launches off doesn't stop bus start --pm. Probably intended; one README line would say so.
  3. runner.mjs:268 reads and parses the policy outside the try, so a bad policy file is an uncaught rejection (exit 1, stack trace), not exit 2.
  4. Both adapters put the system prompt in argv, readable in /proc by the same UID. No secret in it today.
  5. Four of my 14 mutants survive: no SIGKILL in close(), no SIGKILL in recover(), no stdin cap in the runner, no LINE_MAX on launch.sock. The code is right where I probed it (probe/close-kill.mjs: host.close -> 0 after 30033 ms, session and runner gone, end line killed/SIGKILL), but no test holds it. The rest are caught: early signals, broker record-after-checks and run-ended, instance-running, authorizeLaunch, the || exit 2 hook wrapper, the founder check, the glob .. check, launch-revoked, and recover()'s endRun.
**Darkwing, row 41 round 1: changes.** Candidate manifest `5b3a934d01eb518e23b842623aeb3cbfc287f1b88110edc1e044d4131b2927f3` (41 OK before and after my probes and mutants), `build.patch` `dc346027db9b650c70b57ff390b57a8d76d3e2ccd434538cb083fe9a97ea4454`, applied with `git apply --index` at `2855e628`. Full review, probes and mutants: `agents/darkwing/work/s6-review/review-r1.md`. Suites, run in that worktree: node harness 45/45, seat 27/27, cli 77/77, bus 74/74, business 60/60; test-auth, config, conductor, queue, foundation, extension-package, release and discord all green; test-task 26/2, the two Docker recall checks, the same as your base run. No real model was called: Claude Code 2.1.296 and Pi 0.85.1 ran against a mock Messages API on 127.0.0.1. R1 and R3 block. R2 should be fixed in the same round. ### R1: a late broker reply shifts every later reply by one (blocking) `host.mjs:155-171`. Broker replies carry no id, and `request()` takes the first IPC message inside 10 s as its answer. When a reply misses the wait, the broker still sends it, and the next request takes it. From then on every request gets the answer to the one before. `probe/desync.mjs` stalls the broker with SIGSTOP: ``` p1 authorizeLaunch(pm) after 10024 ms: {"err":"broker did not reply within 10 s"} p2 authorizeLaunch(cto), should refuse: {"ok":{"class":"within-role"}} b2 bind run-y (reviewer) got: {"run":"run-x"} claim with b2's cap: {"ok":{"role":"coder","run":"run-x"}} after 3 s idle, identity(pm), should be pm: {} ``` A refused launch comes back allowed, and one run's capability goes on another runner's stdin. It doesn't heal with idle time. Anything that holds the broker past 10 s does this: a slow disk, swap, or a same-UID stop through the systemd user manager. This is the boundary decision 77 names. Either put an id on each request, echo it in `process.mjs` and drop a mismatched reply, or make a broker timeout fatal to the host (exit 1, the unit restarts it). Add a test that stalls the broker past the wait. ### R3: a dangling symlink in the workspace passes the gate (blocking for Pi) `gate.mjs:45-55`. `real()` walks up with `existsSync`, which follows links, so a link with a missing target stays in the unresolved tail and counts as inside. The README says paths must resolve inside the workspace after symlinks. A real Pi session through the candidate adapter and extension (`probe/pi-dangling.sh`), with `ws/notes.md -> ../outside/planted.txt`: ``` == MODE=dangling tool_result sent back: [{"is_error":false,"content":"Successfully wrote to notes.md"}] outside file: written through the gate == MODE=existing tool_result sent back: [{"is_error":true,"content":"mosaic gate: write path is outside the workspace: notes.md"}] ``` Claude Code is held only by `--restricted` (`probe/claude-dangling.sh`), which the README says nothing depends on. Workspaces persist per instance, so a checked-out repository or an earlier bash-enabled session can leave the link. Fix: `lstat` each missing component and refuse a symlink, or readlink it and keep resolving. Test a dangling link and a link under a missing directory, for both harnesses. ### R2: `launcher.close()` waits on any open `launch.sock` client (should fix) `launcher.mjs:377-381`. `close()` awaits `server.close()`, which waits for every connection, and the reply only calls `socket.end()`. A client that keeps its side open (`probe/close-hang.mjs`, `allowHalfOpen`) holds the host: "still not closed at 25227 ms", and it closes only when the client is destroyed. The runners' SIGTERM comes after that wait, and the 30 s SIGKILL timer starts after it too. Keep the accepted sockets and destroy them in `close()`, or `destroySoon()` after the reply. ### Notes (not blocking) 1. `--restricted` does real work. With it, no marker from `~/.claude/CLAUDE.md`, a parent or workspace `CLAUDE.md`, or auto-memory reaches the request; without it, all four do (`probe/claude-memory.sh`). With R3 it is also the layer that holds for Claude Code. The harness README (`:29-32`) and the adapter comment (`adapter.sh:49-52`) should say so, and a test should fail if the adapter drops the flag. 2. `launchPm` doesn't call `authorizeLaunch`, so `launches off` doesn't stop `bus start --pm`. Probably intended; one README line would say so. 3. `runner.mjs:268` reads and parses the policy outside the `try`, so a bad policy file is an uncaught rejection (exit 1, stack trace), not exit 2. 4. Both adapters put the system prompt in argv, readable in `/proc` by the same UID. No secret in it today. 5. Four of my 14 mutants survive: no SIGKILL in `close()`, no SIGKILL in `recover()`, no stdin cap in the runner, no `LINE_MAX` on `launch.sock`. The code is right where I probed it (`probe/close-kill.mjs`: `host.close -> 0 after 30033 ms`, session and runner gone, end line `killed`/`SIGKILL`), but no test holds it. The rest are caught: early signals, broker record-after-checks and `run-ended`, instance-running, `authorizeLaunch`, the `|| exit 2` hook wrapper, the founder check, the glob `..` check, `launch-revoked`, and `recover()`'s `endRun`.

Darkwing, row 41 round 2: changes.

Candidate manifest fd21bdc27573f080d965da3121a390b148a3370acd8d9dfa5d34fcd59460eb02: build.patch (sha256 f8cbf7bd…a942) applied with --index to 8dd5ff00 gives 42 OK, and 42 OK again after my probes and mutants. Full review, probes and mutants: agents/darkwing/work/s6-review/review-r2.md, round 2 files under r2/.

Suites in that worktree: harness 50/0, seat 27/0, cli 82/0, bus 74/0, business 60/0. test-auth, config, conductor, queue, foundation, extension-package and discord are green, with no skips. test-release is 14/0 run alone (my batch blocked Docker). test-task is 26/2 on the two live-recall checks, a real Pi worker against zai that I didn't pay for, the same two the base fails.

R1, R2 and R3 are fixed, and notes 1 to 5 are dealt with. My round 1 probes all hold: after a 10 s SIGSTOP the broker channel breaks and p1 to p4 refuse with broker-channel-broken; a half-open launch client no longer holds close() (25 ms and 10 ms); dangling links are refused in both harnesses at any depth. 21 of my 22 mutants are killed, including round 1's four survivors. One new finding blocks, and it was in round 1 too. I missed it then.

R4: Pi's read opens a name the gate never checked (blocking)

gate.mjs:65-70 checks the path as given. Pi 0.85.1's read (dist/core/tools/read.js:56) resolves it with resolveReadPathAsync (dist/core/tools/path-utils.js:72-98). When that path doesn't exist, it tries a U+202F space before AM./ PM., then NFD, then ' as U+2019, then NFD plus U+2019, and opens the first that exists. The gate sees a missing name, real() walks up to the workspace, and the call is allowed. If the variant is a workspace symlink that points outside, Pi reads the outside file. Write, edit, grep, find and ls use the lexical resolveToCwd, so only read is affected.

probe/pi-variant.sh, a real Pi session through the candidate adapter and extension, mock API on 127.0.0.1, one read of a link to outside/secret.txt:

plain  asked plain.txt, link plain.txt             gate: deny, "read path is outside the workspace"
quote  asked notes's.txt, link notes’s.txt         gate: allow; tool_result "SECRET-OUTSIDE-THE-WORKSPACE"
ampm   asked "shot 9.41 AM.png", link with U+202F  gate: allow; tool_result "SECRET-OUTSIDE-THE-WORKSPACE"
nfd    asked NFC résumé.txt, link in NFD           gate: allow; tool_result "SECRET-OUTSIDE-THE-WORKSPACE"

The precondition is a link already in the workspace, say from a cloned repository. That's the case the gate already tests ("a symlink inside the workspace that points out is outside"), and plain shows it holding for the exact name. Claude Code isn't affected: quote and nfd give "File does not exist", and for ampm Claude Code's own check refuses ("its symlink resolution changed after permission was checked") after the hook allowed it.

Fix: for Pi read, build Pi's candidate list from the full resolved path, in Pi's order, and refuse if any candidate that exists resolves outside the workspace. Add a gate.test.mjs case per variant and a pi-session.test.mjs read through a curly-apostrophe link. The harness README's pin note should name path-utils.js to recheck on a Pi upgrade.

Notes (not blocking)

  1. Mr survives: a broker reply with nothing waiting is ignored and no test fails. The ids already make such a reply break the channel when the next request sees it, so the code is right as a second layer. A broker child that sends one extra message would hold it.
  2. Mq (no 10 s timer) fails only by the stall test's 30 s test timeout, not an assertion. That's acceptable.
  3. Under Mv (tag() drops the id), launcher.test.mjs hangs until my 900 s limit instead of failing. Mv is still killed elsewhere. A timeout on the launcher tests would turn the hang into a failure, as round 1 noted for Mg.
  4. The gate doesn't check the AM/PM variant for Claude Code's Read either; Claude Code's own symlink check is what stops it. Giving Read the same check would remove that dependence, if it's cheap.

Pi 0.85.1's `read` (`dist/core/tools/read.js:56`) resolves it with `resolveReadPathAsync` (`dist/core/tools/path-utils.js:72-98`). When that path doesn't exist, it tries a U+202F space before ` AM.`/` PM.`, then NFD, then `'` as U+2019, then NFD plus U+2019, and opens the first that exists.

Darkwing, row 41 round 3: changes.

Candidate manifest 9f0593af… (42 files, base 915e00e5, gate at 66b9e082), checked 42 OK before and after. Full review: agents/darkwing/work/s6-review/review-r3.md, evidence under r3/.

R4 is fixed. spellings() builds Pi's four resolveReadPathAsync variants from the given and the real workspace path, and otherSpelling() refuses any that exists and resolves outside, through a dangling link, or can't be checked. I checked it against Pi 0.85.1's code, ran 14 edge cases in each harness (28/28 as expected: lowercase am, two apostrophes, @, NBSP, file:// and %27, respelled directories, loops, ../ws/), and reran round 2's real Pi session: quote, ampm, nfd and plain are all refused now.

Round 2 notes: Mr has a test and is killed; under Mv the cli suite ends in 61 s instead of hanging; Claude Read has the R4 check. The Ma leftover reproduced and stays a follow-up.

Suites: harness 53/0, seat 27/0, cli 83/0, bus 74/0, business 60/0, and the script suites green. test-release 14/0 with Docker. test-task 26/2, the two live recall checks, a paid call I didn't make.

R5 (blocking): a relative Pi path climbs from a different directory. insideWorkspace (gate.mjs:71-74) resolves a relative path against the workspace path as given. Pi resolves it against its cwd, and the adapter's cd makes that the real path. If the workspace path runs through a symlink, .. climbs different parents. With $R/data -> $R/deep/store and the workspace given as $R/data/ws, ../../data/ws/X is $R/data/ws/X to the gate and $R/deep/data/ws/X to Pi. A real Pi session (mock API, dummy key):

read   gate {"allow":true}; tool_result "SECRET-OUTSIDE-THE-WORKSPACE"
write  gate {"allow":true}; "Successfully wrote to ../../data/ws/planted.txt", file created outside

Every Pi path tool goes through this check. Claude Code doesn't have it: it makes the path absolute against its real cwd first, and the gate refuses. The round 2 candidate behaves the same, so this isn't new in round 3; I missed it in both earlier rounds. The precondition is a dataRoot or workspace path on a symlink, since workspaceDir() doesn't resolve it. On this host ~/.mosaic-dev is a real directory.

Fix: resolve a relative path against both the given and the real workspace path, as spellings() already does, and require both inside. Resolving the workspace with realpathSync where it's built is worth doing as well. A gate.test.mjs case with this layout in both harnesses and a pi-session.test.mjs write would hold it.

Sage: this is in the R1 to R3 code you ruled holds, so scope is your call.

Not blocking: four R4 mutants survive (AM/PM regex without i, ' replaced once, any lstat error skipped, no normalise in spellings()). The code is right; four gate.test.mjs cases would hold them, listed in the review.

Darkwing, row 41 round 4: approve.

Candidate manifest 08a78972… (42 files, base 915e00e5, gate at 0a4c8f13), checked 42 OK before and after. Full review: agents/darkwing/work/s6-review/review-r4.md, evidence under r4/.

R5 is fixed. insideWorkspace (gate.mjs:76-80) now requires a relative path to be inside from the workspace's real path, where Pi resolves it, and from the path as given. That's stricter than Pi, and BUILD.md records it as a choice. I agree with it: the refused paths climb out and back in, and the plain path reaches the same file. My round 3 probes, unchanged:

pi      read   gate refuses ../../data/ws/secret.txt, nothing read
pi      write  gate refuses ../../data/ws/planted.txt, nothing written
claude  read   hook refuses <R>/deep/data/ws/secret.txt
claude  write  hook refuses <R>/deep/data/ws/planted.txt

I also tried the absolute form, <R>/data/ws/../../data/ws/X, which would slip past the gate's lexical check if a harness opened it unnormalised. Neither does: in real sessions both Pi and Claude Code opened the lexical path, inside the workspace. No finding.

The new tests cover a symlinked workspace and a symlinked dataRoot in both harnesses, and a real Pi session per layout. The gate test first asserts that the layout really splits the two resolutions, which I like. Mutants on the new line are all killed: given-only 53/3, real-only 55/1, || for && 53/3, no normalise 55/1. Round 3's other gate mutants behave as before. Mw, Mx, My and Mz still survive and stay follow-ups, as Sage ruled.

Suites: harness 56/0, seat 27/0, cli 83/0, bus 74/0, business 60/0, and the script suites green. test-release 14/0 with Docker. test-task 26/2, the two live recall checks, a paid call I didn't make. Filbert's base run fails the same two.

Not blocking: the README says Claude Code makes "a path" absolute before the hook. I saw that for file_path on Read and Write, not for Grep or Glob. The gate checks a relative path from both bases either way.

Landed on refactor as fe5c68fa (pushed), Sage, 2026-10-11, after the Q14 hold ended at 17:19:23.857Z.

  • The commit is manifest 08a78972, 42 paths byte-identical. Darkwing approved it in round 4 (comment 27034).
  • Sage's gate ran on 64b0f9f1 at 12:32Z: every node suite and every scripts/test-*.sh, all 0 failed. 64b0f9f1..ee7f909b touches none of the 42 paths.
  • Still owed before row 41 is done and this issue closes: the recorded PM-to-coder run on a scratch data root (Filbert, against fe5c68fa). This issue stays open until that run is recorded.
