Codex's uncommitted fix for #2531 is correct, but it doesn't change any behavior and it doesn't address the trail finding it was written for. #2573 and #2574 are in good shape.

Where the three PRs stand

The two scratchpad worktrees for #2573 and #2574 have no uncommitted changes. The only unfinished work is the diff in this worktree.

Review of the uncommitted diff (#2531)

The change has no effect today. It limits WithAgentWorkingTree to TurnStart/TurnEnd. But the only thing that reads that flag is rehomeSessionToCurrentWorktree, and it's only called from InitializeSession (turn start) and SaveStep (turn end). Subagent and tool-use events never read it. So it's a reasonable guard for future code, not a fix.

It doesn't address the open finding (trail 1378, 01M3897YMYH7). The finding is about the directory change itself. Task-scoped events move the whole hook process into the subagent's worktree. After that, the tool-use repoRoot, the pre-task untracked baseline, and the subagent-end change detection all resolve against the child tree, while the results are written to the parent session. Codex deliberately kept that move, reasoning that the subagent's files live in the child tree. That's defensible, but it's a design call the finding disputes, and nothing in the diff shows the result is correct. Resolving the finding on the strength of this diff would be wrong.

The question to settle before choosing a direction: for Claude's Task tool with isolation: worktree, the pre-task snapshot and the completion diff need to run in the same tree:

• If PreToolUse(Task) reports the parent's working directory and SubagentStop reports the child's, the baseline comes from one tree and the diff from the other. Every untracked file in the child would then show up as subagent work.
• Separately, the child-relative paths recorded on the parent's task record make homeHoldsPendingContent true. That blocks re-homing the parent session later.

Neither case is tested; the new test cases only check where the process ends up and whether the flag is set.

Checked, no problem:

• The TodoWrite task-checkpoint hook (SaveTaskStep → migrateShadowBranchIfNeeded) is dispatched separately and never goes through the working-directory follow. It can't rebase the parent's shadow branch onto the child's HEAD.
• The doc edits match the code.

Verification: Codex's session ended during its full mise run check, and it never reported a result. I ran only TestFollowAgentWorkingDirectory (passes) and gofmt (clean). The full check still hasn't been run on this diff.

Options for #2531

1. Commit it as a guard and reply to the finding with the reasoning for keeping the move. Add a test where the task starts and stops in different trees.
2. Stop following task-scoped events: skip the move for SubagentStart, SubagentEnd and ToolUse. This is what the finding asks for, and it matches main. The cost is that a subagent's work in a child worktree goes uncaptured until the parent's next turn.
3. Follow only when start and end agree: record the baseline tree on the task record and discard the capture if the tree at completion differs.

I'd go with option 3, or option 2 if you want the smallest diff. With option 1 the finding stays open. Nothing has been committed or pushed. Tell me which option and I'll implement it.

Agreed: keep following in every case, including subagent start/end and tool use, and fix what breaks. I wrote a probe test (cmd/entire/cli/integration_test/worktree_follow_task_test.go, uncommitted) that confirms following is currently incomplete. All three scenarios fail today:

Why

• Per-turn baselines are per-worktree. The untracked-file snapshots taken at turn start and subagent start are written to that worktree's own .entire/tmp. The end hook runs in the other worktree and doesn't find them. It then treats every untracked file there as new, and the original snapshot files are never cleaned up.
• prompt.txt has the same problem. It's also written per-worktree at turn start. A turn that ends in another worktree reads that worktree's copy: empty, or left over from earlier turns there.
• The pending-content guard can't tell where work happened. It counts any task record or touched file as pending content "at home", so a subagent's work in the worktree keeps the session pinned to the parent.

Proposed fix

1. Record the turn's starting worktree in the shared session state. The end hook then loads the start baseline and prompt.txt from that worktree when its own copies are missing, and deletes them there afterwards. For subagents it checks the current worktree first, then the turn's starting worktree, then the session's home worktree.
2. Don't compare against another worktree's snapshot. When the baseline came from a different worktree, skip new-file detection from git status and take new files from the transcript instead. Scans that were skipped already work this way.
3. Record where task records and tool-use file lists were made. Then pending content only counts as "at home" if it was produced there, and work produced in the current worktree lets the session re-home.
4. Keep the event-type guard from Codex's uncommitted diff, since those events must still not authorise the parent to re-home.
5. Turn the probe into real tests covering the three scenarios above, plus Codex subagent start/stop and tool-use file lists.

Rough size is about +350/−40 lines, landing as 2–3 more commits on #2531.

The one trade-off to accept is in point 2: after a move, files created by shell commands that the transcript never names are missed. That's under-capture. The alternative is claiming files that were already in the worktree, which the codebase already treats as worse (it steals attribution).

Should I go ahead? And do you want it on #2531, or as a separate PR stacked on top so #2531's diff stays readable?

API Error: Can't reach the API server — check your internet or DNS (ENOTFOUND)

Waiting on the full check rerun. It notifies when it finishes, and I'll report then.

Subagents and tool use now follow the agent into worktrees in every case where the agent reports its working directory. mise run check passes (lint 0 issues, unit + integration + canary green). Nothing is committed or pushed yet; the diff is 18 files, +692/−65.

What changed

• Baselines are found across worktrees. The turn-start and subagent-start snapshots are written in the worktree where that hook ran. The session now records which worktree the turn started in, and the end hook looks there and at the session's home, uses the snapshot, and deletes it.
• No over-claiming after a move. A snapshot from another worktree can't tell which untracked files were already there, so new files then come from the transcript only. That's the same fallback as a skipped scan. The cost: after a move, a file created by a shell command that the transcript never names is missed rather than wrongly claimed.
• The turn's prompt.txt moves with the agent to the worktree where the turn ends.
• The session no longer gets pinned to the parent. Every state update that adds files or task records now records which worktree it came from. Work recorded in the worktree the session is moving to no longer blocks the move. Work in both trees still keeps it in place, and existing saved steps always do.
• Re-homing also happens at a turn end with no saved step, such as a turn where only a subagent did work. Before, only turn ends with file changes re-homed.
• Factory Droid now follows too. Its docs confirm every hook payload includes cwd, but Entire wasn't parsing it; it's wired on all five events now.
• Codex's uncommitted diff is kept: subagent and tool-use events still don't, on their own, count as proof that the parent session moved.

Tests

• The three scenarios that failed earlier now pass:
  • a mid-turn move, including the prompt carry;
  • a task that starts in the parent and finishes in the worktree;
  • a task entirely in the worktree.
• New: Codex tool-use files recorded in the worktree, and in both trees.
• New: the re-home guard's cases, and Droid parsing cwd on every event.

Subagent support across all agents

Follow-ups (not done)

1. OpenCode subagents are a separate bug. Its plugin reports every new child session as a top-level session.
2. External agents would need a protocol change. Adding an optional cwd field to the external-agent protocol would let them follow.
3. Stale comment in completeSubagentTaskRecord. It says Copilot's subagent-end has no correlation ID, but it does now.

Your call

1. Where it lands. This is a big addition on top of #2531's 15 commits. I can commit it as 2–3 commits on #2531, or put it in a separate PR stacked on top so #2531 stays readable. I'd go with stacked.
2. Trail 1378's open finding. Once pushed, it's addressed: task events still follow, but no longer mis-record work against the parent.

SESSION-ATTACH-WORKTREES.md is still untracked and won't be included.

I committed the subagent-following fix onto #2531 as three commits and pushed. The comment is fixed, and the trail 1378 finding is resolved. CI on #2531 is still running; I'm watching it and will report when it finishes.

Why on #2531 rather than a stacked PR: #2531 is what makes subagent and tool events move into the worktree. On its own it would merge the bug where a worktree's existing untracked files get recorded as the agent's work, so the fix has to ship with it. The three commits:

• 710f6b90b8: Factory Droid now follows the agent into worktrees; it sends cwd on every hook and Entire now reads it.
• 6029634216: the core fix, with its tests and docs.
• 3d168aec9b: change 3, the corrected Copilot comment.

Checks before pushing: mise run check passed on the fix, and lint was clean (0 issues) on the final tree, formatting included. The only change after the full check was comment wording.

Trail 1378: finding 01M3897YMYH7 is resolved, with a note pointing at 6029634216 and the new tests.

SESSION-ATTACH-WORKTREES.md is still untracked and wasn't included. Nothing is merged.

All six leftover findings are closed, and none are open on the three trails now. entire trail finding list only shows findings on the latest code by default, so these six, attached to older commits, were hidden when I checked earlier.

I checked each against the pushed code before closing it. I marked them "resolved" rather than "dismissed", because each was a real issue that a later commit fixed. Dismissing would record them as not valid.

#2531 (trail 1378)

• Failed directory-change rollback: that path no longer exists. The hook now checks whether the target worktree is enabled before moving, so there's nothing to roll back (79d1d794c6).
• Copilot never set Event.CWD: every Copilot event now sets it (7aadbb36ce).
• Hook could run in a worktree where Entire isn't enabled: it now checks the target worktree's settings and stays put if Entire is off there (b60a65d1f4, 79d1d794c6).
• Logs went to the old worktree after a move: the log file now moves with the hook (2a31d8cc6b).

#2574 (trail 1414), both fixed in 2339952584 with regression tests

• Leftover SQUASH_MSG attached old checkpoint trailers: trailers are only inherited when the staged content matches a commit listed in SQUASH_MSG; otherwise they're stripped.
• Condensing into a checkpoint that already existed: the chosen target is rechecked and flagged if it already exists.

#2573 (trail 1413) never had any findings.

CI on #2531's new head is still running; I'll report when it finishes.

CI on #2531's new head (3d168aec9b) passed all 15 checks. The only red item is the "Entire Gates" check, and that's just the approvals gate: it needs 1 reviewer, has 0, and self-approval isn't allowed.

The trail's other gates passed at that commit. The automated review ran again on the new head and found nothing blocking, and no findings are open.

So all three PRs (#2531, #2573, #2574) are now in the same state: CI green, no open findings, waiting on a reviewer's approval. Nothing is merged.

Yes, now it has been. I built a fresh entire binary from the pushed head (3d168aec9b) and ran 17 scenario checks with real git hooks installed in new multi-worktree repos. All 17 pass.

To show the checks can actually catch these bugs, I ran the same script against the binary from just before the fix (e92ae9ff0c). 9 of the 17 fail there.

S4 and S6 confirm the existing safeguards didn't loosen. In every scenario the hooks run with no agent process above them, so ancestry can't mask a failure.

Earlier test runs, for completeness:

• mise run check on the fix: the integration suite and canary build their own binary from the tree.
• CI green on the pushed head.

Not tested:

• Real-agent end-to-end runs: these make paid API calls, so they only run when you ask.
• Codex in the real-binary scenario: it's covered by the integration test only (tool-use files recorded in the worktree, and in both trees).

The script is scratchpad/scenario-follow-all.sh BIN LABEL if you want to rerun it.

Neither needs fixing. S4 and S6 are the two passing on both binaries because they aren't bug cases. They check that the fix didn't loosen existing safeguards:

• S4, uncommitted work in both trees: the agent edited the parent, didn't commit, then moved into a worktree. The parent now holds saved checkpoint steps that are tied to the parent worktree. Moving the session would leave those steps unreachable. So staying homed in the parent is correct, and the worktree's commits still link to the session as a guest.
• S6, a payload without cwd: a hook that runs in the launch directory but doesn't say where the agent is must not pull a session back from the worktree it moved to. Without this guard, a session would bounce between the parent and the worktree on every hook for agents whose payloads have no cwd (Cursor, OpenCode, external agents).

Both produce the same result before and after, which is what should happen. All 17 checks pass on the pushed head.

Not quite. I'd do one more focused pass first. The follow-up commit 6029634216 is about 600 lines I wrote tonight, and nothing independent has reviewed it except Entire's automated trail review. That review is clean (0 findings at any severity), but it's one reviewer.

What I'd check, because it's where I'm least certain:

1. Pending-content stamping in MutateSessionState: whether any writer adds files or task records without going through it. Condensation and session init save state directly, and a missed writer means the re-home guard sees wrong locations. I'd also check nested frames.
2. prompt.txt carry when the session can't re-home: if the session stays homed in the parent, carrying the prompt into the worktree may put it where that turn's checkpoint doesn't look.
3. Hook cost: turn end and cleanup now do an extra session-state read, and path metadata resolution when the agent moved. That should be cheap, but it's worth confirming against the hook time budgets.
4. Windows paths: a new check compares worktree paths with filepath.Clean, which doesn't normalize case, while the older check resolves symlinks. That may differ on Windows or macOS casing.
5. #2531's PR description: it doesn't mention subagent following, the baseline lookup across worktrees, or Droid yet, so a human reviewer would miss that scope.

After that pass, plus fixes for anything real, it's ready for human review. #2573 and #2574 are ready now: they're small and already had their findings addressed.

Want me to run the pass now?

Description drafted. Waiting on the full check before committing and pushing.

The review pass found two real bugs; both are fixed and pushed to #2531 (head b3ea349d41). The real-binary scenario passes 17/17 on the new head. CI and the trail review are still running, and I'll report when they finish.

Fixed:

1. Adopt copied the source session's locations. session adopt clones the source state, so it carried over the source repo's turn and pending-work worktrees. The guard only read that the conservative way, so it was never wrong, but the data was false. Adopt now records the moved-over work as pending in the target worktree (Locate adopted content in the target worktree).
2. The prompt.txt carry moved the whole file. The file collects every prompt since the last condensation. If the session couldn't re-home, earlier turns' prompts were duplicated into the worktree's checkpoint and removed from the parent, where mid-turn commits still read them. Now only the current turn's prompt moves (Carry only this turn's prompt to the worktree the turn ended in). The new test fails on the old behaviour.

Checked, no change needed: 3. Other state writers: apart from adopt and import, every writer that adds files or task records goes through MutateSessionState. Import leaves the location empty, which the guard treats conservatively. 4. Hook cost: one extra small state read per baseline lookup, and worktree metadata is only resolved when another tree is involved. 5. Path comparison: the new check compares paths the same way the existing home-worktree check does, using paths from the same resolver.

PR description: rewritten to match what the PR contains now. It notes that idle sessions and squash trailers moved to #2573 and #2574, and covers the subagent following, the Droid support, the testing done, and the follow-ups.

mise run check passed before the commits, and lint is clean on the pushed tree. Once CI and the trail review come back clean, all three PRs are ready for human review.

Trails:

For Slack:

Three PRs ready for review, all CI green: • #2531: sessions now follow the agent into worktrees, including subagents, so you no longer need entire session attach when an agent works in a worktree. https://entire.io/gh/entireio/cli/trails/1378 • #2573: hooks no longer delete live idle sessions. https://entire.io/gh/entireio/cli/trails/1413 • #2574: squashed or redone commits keep their checkpoint trailers. https://entire.io/gh/entireio/cli/trails/1414

One caveat before posting: the automated agent review for #2531's latest push exited with an error instead of running. CI there is green and the earlier review was clean. I'm polling to see if the review retries on its own and will tell you the result.

Three PRs ready for review, all CI green: • #2531: sessions follow the agent into worktrees (subagents too), so no more entire session attach. https://entire.io/gh/entireio/cli/trails/1378 • #2573: hooks no longer delete live idle sessions. https://entire.io/gh/entireio/cli/trails/1413 • #2574: our earlier squash support covers GitHub squash merges, which already combine trailers. This one covers squashes and redos done locally: merge --squash with your own message, or git reset and recommitting. Those used to lose their trailers, so the session dropped off the trail. https://entire.io/gh/entireio/cli/trails/1414

One thing to check before posting: the "earlier squash work" is my reading of #2574's own description, which says GitHub squash merges already produce the multi-trailer shape that the server reads. If you meant a different piece of squash work, tell me which and I'll adjust the wording.

The #2531 review retry check is still running.

Three PRs ready for review, CI green: • #2531: sessions follow the agent into worktrees, no more session attach. https://entire.io/gh/entireio/cli/trails/1378 • #2573: hooks stop deleting live idle sessions. https://entire.io/gh/entireio/cli/trails/1413 • #2574: GitHub squash merges already worked; this fixes local squashes and resets that dropped trailers. https://entire.io/gh/entireio/cli/trails/1414

The automated review on #2531's latest push still hasn't run: after 12 minutes of polling, its reviewer process keeps exiting with an error, and it didn't retry on its own. No findings are open. CI on that commit is green, and the earlier review passed with no findings, so only the last two small commits (the adopt fix and the prompt carry) are unreviewed.

There's no command to re-run the review. Pushing an empty commit would trigger it, but that adds a meaningless commit to the PR, so I haven't. You can post the Slack message as is. Or I can push the empty commit, or you can re-run the review from the trail page if it has a retry button.

• #2574: two fixes for commits that lost their trailers. Local squashes (merge --squash with your own message) now keep them; GitHub squash merges already did. Resets (git reset then recommit) now keep them too. https://entire.io/gh/entireio/cli/trails/1414

If you meant splitting #2574 itself into a squash PR and a reset PR, I can do that. Both rely on the same fix that stops post-commit from writing into an older checkpoint, so that fix would ship first and the other PR would stack on top of it.

The split branches are built; rerunning mise run check on both (waiting for the other session's lint to finish).

I haven't touched #2574, and I'd hold the split until we decide how to handle this. Today at 16:27 (+0200), Stefan pushed 4a5df627d0 to #2574: an adversarial review written as tests, 15 in all. 10 of them fail on purpose, marking cases where the PR does something a user wouldn't want. Finishing the split means force-pushing #2574's branch, which would drop his commit.

What his failing tests say

For squash:

• Declining still links: you git merge --squash a teammate's branch whose checkpoint isn't on this machine, commit with -m, and answer "n" to linking. The session's work is still written under the teammate's checkpoint ID.
• A regression from main: squashing with an edited file strips git's own seeded trailer.

For reset:

• Accidental matches inherit trailers: four cases, such as an identical lockfile, the same deletion in both, or an old reset that later ordinary commits never close off.
• The walk goes too far: reset --soft main after merging main walks through merge commits into history that's already on main.
• Editor commits write to the wrong checkpoint: the inherited trailer lands after the new one, so post-commit writes the session's work under the inherited, foreign ID.
• Links still get lost: an amend fold, or unstage/stash after reset --soft overwriting ORIG_HEAD.

His other 5 tests are guards that already pass.

Where things stand

• The new reset branch peyton/redo-trailers is pushed, but there's no PR for it yet. It's built from the tree before Stefan's commit, so it doesn't have his tests.
• The squash-only branch is built locally, and mise run check passes on both. The one test failure I hit was a broken shared OpenCode test cache on this machine, not the code; I moved the cache aside rather than deleting it.
• #2574 is unchanged, at Stefan's commit.

What I'd suggest

Split his tests by topic: the squash ones go to the squash PR (#2574) and the reset ones to the reset PR. Then fix the failures in each PR before either goes to review, starting with the two squash bugs. The "declining still links" one is a real provenance bug, and the seeded-trailer one is a regression from main.

Since this rewrites a branch Stefan just pushed to, I'd check with him first. You'll have to run the force-push yourself anyway, and I'll give you the exact command once the branch is ready.

Want me to go ahead that way, or leave #2574 as one PR while the failures get fixed?

I'll run those two scenario scripts against fresh binaries of both branches once the checks finish.

Full checks and real-hook scenarios are running on both branches; I'll report when they finish.

Descriptions are ready; waiting on the reset branch's final check.

Both branches are ready: the full check passes on each with lint clean, and the real-hook reset scenario is fixed. The last step is replacing #2574's branch, which needs a force-push, so it's yours to run.

Squash PR (becomes #2574), 11 files, +985/−27:

• the squash commits and the post-commit provenance fix;
• Stefan's 3 squash tests, still authored by him;
• the stale-message and target-recheck fixes;
• keeping trailers when a squashed file is edited before committing;
• never condensing into an inherited trailer.

Reset PR (new, stacked on #2574), 8 files, +1128/−2:

• the reset feature;
• Stefan's 12 reset tests, still authored by him;
• the redo-detection fix described below.

All 10 of Stefan's failing tests now pass, his 5 guards still pass, and the real-hook reset results match the old #2574 table. Along the way the real-hook scenario caught one regression my first fix introduced: keeping a backup branch before a reset stopped the trailers from being inherited. It's fixed, with a test.

Run this, ideally after giving Stefan a heads-up. His commit stays on #2574, split into two commits that keep him as author. The lease makes the push refuse if anyone has pushed to either branch since I checked:

After that I'll open the reset PR against #2574's branch and update #2574's title and description. Both descriptions are drafted and credit Stefan's review.

One thing to decide first: #2574 has carried a CLAUDE.md line since an earlier session: "check the trail's findings after every push to an open PR." That's a repo-wide process rule, unrelated to squash. Should it stay in #2574 or be dropped?

The split is live. CI and the trail reviews are running on both PRs, and I'll report when they finish.

• #2574 (squash): retitled "Squashed commits keep their checkpoint trailers", 9 commits on main, description updated to credit Stefan's review.
• #2582 (reset): new, stacked on #2574, 3 commits.

The CLAUDE.md line is still in #2574 because you haven't decided yet. Tell me whether to keep or drop it.

All three branches are queued for their full checks. Once they pass, I'll push, then resolve or dismiss each finding.

Trail 1414 has no open findings. Waiting on the reset and 1378 checks before pushing those two and handling their findings.

Trail 1420's finding is resolved and the two 1378 findings that don't hold are dismissed with explanations. The other three 1378 findings get resolved once the merged branch passes its check and is pushed.

All three PRs are pushed and none of their trails has open findings. CI and the new trail reviews are running, and I'll report when they finish.

• #2531 (1378): fixed three findings.
  • The unlinked-commit notice no longer fires on unrelated human commits.
  • The per-mutation snapshot no longer allocates, pinned by a zero-allocation test.
  • Two doc comments are back on their functions.
  • I dismissed two findings, with reasons recorded: one was against old code, and the other describes a symlink risk the rooted file access already prevents.
  • I also merged in main after Victor's "update branch". That brought in the Gemini removal, so I dropped Gemini from the PR description.
• #2574 (1414): its three findings were already fixed by the inherited-trailer marker and are now resolved. New commit: inherited trailers now go above git's comment block, so git commit -v no longer drops them.
• #2582 (1420): the finding was wrong about the comment block being dropped, but it pointed at the same commit -v gap, now fixed with a test that fails on the old code.

Every branch passed mise run check before its push. The CLAUDE.md line in #2574 is still waiting on your keep-or-drop decision.

The fix is committed on the reset branch, which is running its full check and pushes once that passes. I'm also rechecking #2531's CI.

I'll tell you as soon as it's pushed. The full check takes about 5 minutes.

#2582 is pushed (85096bd604). Its full check passed first with lint clean, and trail 1420's finding is resolved.

#2531 still has no CI on its current head (330ab6bde5). I pushed it while GitHub's API was down, and more than an hour later no workflow has run for it. The earlier red run is Victor's "update branch" merge (83a7a49bd7), which failed because CI couldn't download a Go module (golang.org/x/crypto); the code didn't fail anything. My local mise run check on the same merged code passed.

A new push is the only way to trigger CI for that head. Closing and reopening the PR would also work, but you've asked me not to do that. Should I push an empty "Re-run CI" commit to #2531?

The finding was valid, and the fix is committed on #2531. It's in the full check now and pushes automatically once that passes, which will also start the CI run that didn't trigger last time.

• The problem: a baseline copy that couldn't be read stopped the whole search across worktrees. The caller then had no baseline, so every untracked file was treated as new.
• The fix: an unreadable copy is now skipped and the next worktree is tried. If a baseline exists but can't be read anywhere, it's marked unreadable, which turns off new-file detection from git status. The TodoWrite checkpoint hook gets the same guard.
• Tests: three new tests fail on the old code and pass with the fix.

I'll tell you when it's pushed and resolve the finding then.

The finding fix is pushed (982ca4e94a) and the finding is resolved.

CI still wasn't running on #2531 because the PR conflicted with main after the Antigravity merge. I merged main in and resolved three small conflicts, keeping both sides. The merge is in its full check now. It pushes when that passes, and I'll confirm CI actually starts this time.

The duplicate helper is removed and the full check is running again. #2531 isn't pushed yet; I'll push once the check passes and tell you.

I haven't pushed #2531 yet. The full test suite is running now (about 5 minutes), and it pushes only if the tests pass.

Lint on #2531 will still fail after the push. The cause is on main: since the org-invite PR merged, main's own Lint has been red (the string expired repeated in auth.go/org_invite.go), and #2531 doesn't touch those files. It needs a small separate fix on main; I can do that as its own PR if you want.

Only #2531 conflicts; #2574 and #2582 merge cleanly.

#2531's conflicts are already resolved in a local merge of the latest main:

• Main's Antigravity changes, in lifecycle.go, state.go and HandleTurnEnd; I kept both sides in each.
• A duplicate worktreeEnv test helper that #2573 also added; I kept main's copy.

The merge isn't on GitHub yet, so the PR still shows as conflicting. The full test suite is running on it and pushes automatically when it passes, in about 5 minutes. The only other problem is lint, which fails because of main's goconst issue, not this merge. I'll confirm once the push lands and GitHub shows it as mergeable.

All five trail 1414 findings were valid, and the fixes are committed on #2574 and #2582. The full check is running on both branches, and each pushes when its check passes (about 10 minutes for both). I'll resolve the findings after the push.

• Medium, -m squash subject. Committing a squash with -m "#42 fix login" made the trailer the commit subject. Inherited trailers now go above git's comment block only for editor-composed messages. A -m/-F message keeps its # lines as normal text, and the trailer is appended at the end. The reset side gets the same fix. Both have a test; I haven't confirmed these two fail on the old code.
• Low (×4), cleanup.
  • Refreshed stale comments that still said squashes are skipped, or that the function "reports whether it took over".
  • Renamed squashStagedContentMatches to squashTouchesStagedPath, since it now compares paths rather than content.

#2531 is pushed and GitHub shows it as mergeable. Lint will still fail there until main's goconst issue is fixed.

#2574 and #2582 aren't pushed yet. The fix is in ("message" is now a named constant, lint 0 issues), and the full check is running on both. Each pushes when it passes, in about 10 minutes total; then I'll resolve the trail 1414 findings.

All three 1378 findings are fixed and committed. Lint and the full tests are running, and I'll push when they pass.

• Medium: carryTurnPrompt now opens the source worktree's .entire with the write-capable opener before trimming its prompt.txt.
• Low: it now logs when prompt.txt shrank since the turn started, and the comment explains why that happens.
• Low: the chdir now has a comment saying why a process-wide directory change is safe: each hook is its own process.

The new 1414 finding was valid, and the fix is committed on #2574 and merged into #2582. None of #2531, #2574 or #2582 has pushed yet; I'll resolve the findings on 1414 and 1378 once they do.

The bug: after a squash commit had been condensed, amending it silently skipped condensation, because every trailer on it now had a checkpoint. A normal amend re-condenses into the session's own checkpoint.

The fix: in that case, post-commit falls back to the last trailer (where the new one is stamped) as an existing target, and the existing guard only lets the session being amended write there. It has a new unit test, and the full strategy package and the squash integration tests pass.

Pushes: #2531 pushes when its test run finishes (its lint shows only main's goconst issue). Then #2574 and #2582 push after their full checks, about 15 minutes for all three.

The #2531 test run finished; the queued job pushes it next and then checks the split branches. I'll report when they land.

All three PRs are pushed, and none of their trails (1378, 1414, 1420) has an open finding.

CI: full checks passed before each push; CI on the new heads is still running. #2531's lint will stay red until main's goconst issue in auth.go/org_invite.go is fixed, which is outside this PR.

Still open: the CLAUDE.md line in #2574 needs your keep-or-drop call.

#2531's conflicts are resolved and its lint failure is fixed, in a local merge that isn't pushed yet. In doing that I found main is broken, and my #2574 caused it.

Main is broken. #2574 merged at 17:11 UTC and added a parameter to tryAgentCommitFastPath. Two Antigravity tests that landed on main separately still call the old signature, so the strategy tests no longer compile. Main's Tests run for 3b0d0526b9 failed.

Hotfix (peyton/fix-main-build, new branch off main):

• passes nil for the new parameter in those two test calls;
• fixes main's lint failure by making "expired" in auth.go a constant;
• lint is clean.

#2531:

• merged main in and resolved the two doc conflicts, keeping both sides;
• applied the same two fixes, since #2531 won't build or lint without them;
• the merge only differs from main by those fix lines.

Both are running full checks now. Each pushes when its check passes, and I'll open the hotfix PR then. After the push, #2531 should show as mergeable, with lint passing.

#2582 is now based on main. It'll need main merged in too once the hotfix lands, and I'll handle that next.

The main hotfix PR is open as #2594. It restores main's strategy-test build and lint, and passed the full check.

#2531 isn't pushed yet. The merge brought PostCommit back over the maintainability limit, so I moved its commit-tree resolution into a helper, and lint on #2531 is now clean. The full tests are running, and #2531 pushes once they pass, in about 5 minutes. I'll confirm GitHub shows it as mergeable.

#2531 is pushed (3b5dadd863) and mergeable, with lint clean and the full tests passing locally. It shows BLOCKED only because it still needs a reviewer's approval.

• Main hotfix #2594: open, full check passed. Until it merges, main's strategy tests don't compile and its lint stays red.
• #2582 (reset): GitHub moved its base to main when #2574 merged. It needs main merged in, but if I do that before #2594 lands, it would fail to compile for the same reason. I'll update it once #2594 merges. The alternative is copying the hotfix's two fixes into #2582 as well, like I did for #2531; tell me if you'd rather I do that now.

No, it's a separate fix, though it's in the same area. Trail 1416 is PR #2577, "stop carrying forward files a skipped-hook commit already took" (your branch fix/skipped-commit-carry-forward, 3 commits from 2026-09-23/24).

• What it fixes: after a commit made with the hooks skipped, the next hooked commit re-carried files the earlier commit had already taken. It keeps a file that matches HEAD only if it was edited again since the snapshot.
• Why it's independent: it touches only content_overlap.go, its test, and one new integration test. None of #2531, #2574, #2582 or #2594 touch those files, so there's no conflict and no dependency in either direction.

The only interaction is conceptual: it can shrink a session's FilesTouched. #2531's pending-content tracking only reacts when files are added, so shrinking is safe there.

The trail 1416 description is written. The full check on #2577 (merged with current main) is still running, and I'll tell you when it's done.

On readiness so far: the fix works.

• Real-hook scenario: on main's binary, a commit made with hooks skipped leaves a stuck shadow branch and a permanent [temporary] carry-forward on every later hooked commit. On #2577's binary both are gone. A file edited again after the skipped commit is still carried forward, so real pending work isn't dropped.
• Code review: the change is small (+174/−7, mostly tests) and reuses the existing working-tree check. I found nothing wrong.
• PR state: CI is green except the approvals gate, and its one trail finding is already resolved.

#2577 is based on main from before #2574 merged. It merges cleanly, but its CI will fail on main's current test-compile break until the hotfix #2594 lands.

Yes, that's what the table in my last message was. Here's exactly what I ran.

Two binaries

• main: bin-main/entire, built from current main plus the hotfix, so the strategy code is exactly what's on main.
• fix: bin-cf/entire, built from #2577 merged with the same main, which is what it'll be once merged.

One script, run against each (scratchpad/scenario-skipped-hook.sh <binary> <label>), in a fresh repo with entire enable and the real git hooks installed:

1. An agent turn writes a.txt, through real Claude Code user-prompt-submit/stop hooks with a transcript.
2. Commit a.txt with every hook skipped: git -c core.hooksPath=/dev/null commit. That's the same effect as LEFTHOOK=0 or a hookless GUI client.
3. Another turn writes b.txt, then a normal hooked commit.
4. Check for leftover shadow branches and entire checkpoint list for [temporary].
5. One more turn and hooked commit, then check again.
6. Guard case: another turn's d.txt is committed with hooks skipped, then edited again on disk and not committed. It must still be carried forward.

Results

• main binary: the bug reproduced. One stuck shadow branch and a [temporary] carry forward entry after the next hooked commit, still there after the one after that (4 failures).
• fix binary: all 6 checks pass. Nothing stuck, hooked commits still linked, and the re-edited file is still carried forward.

The only difference from the PR's own verification is the agent: I used simulated Claude Code hooks, where the PR used a live Vogon session. Vogon is free and deterministic, so I can run that path too if you want it covered exactly. The full mise run check on the fix is still running.

Almost. Everything so far says yes, but the full mise run check on #2577 (merged with current main) hasn't finished, so I can't call it ready yet.

Done and good:

• The bug reproduces on main's binary, and it's fixed on the branch's, with real hooks.
• A file edited again after a skipped-hook commit is still carried forward, so the fix doesn't drop real pending work.
• The diff is small and reuses the existing working-tree check; I found nothing wrong.
• CI is green except the approvals gate, the one trail finding is resolved, and the trail description is written.

Before a reviewer sees it:

1. The full check has to pass. It's still running.
2. #2594 should merge first. #2577 is based on main from before #2574 merged. Once GitHub builds it against current main, CI will fail on main's test-compile break (not this PR's fault) until the hotfix #2594 lands.

If the check passes, it's ready once #2594 is in. I'll tell you when the check finishes.

You're right. #2577 has no code dependency on #2594: its diff neither touches nor needs anything from the hotfix. I only merged the hotfix in so its tests would compile on top of current main, which is broken on its own.

On its own branch, #2577's CI already passed (16 checks) on 77dff4b46a. The only thing #2594 affects is GitHub's re-test against current main after main moves, and that would fail for every open PR right now, not just this one.

So it's ready for human review once the full check I'm running finishes clean, and nothing needs to merge first. I'll confirm when the check is done.

I've merged main into #2582 (reset); the merge was clean, its diff against main is now only the reset work, and it's queued for its full check before pushing. The #2577 check is still running. I'll report both when they finish.

Yes, it's ready for human review. The only piece of the full check still running is the Vogon canary, the last step.

Evidence:

• Lint: 0 issues.
• Unit and integration tests: all 92 packages pass, with no failures in the log so far.
• Real-hook reproduction: on main's binary the bug reproduces; on the branch's binary it's fixed, and a file edited again after a skipped-hook commit is still carried forward.
• CI on the PR's head: green except the approvals gate.
• Trail: the one finding is resolved, and the description is written.
• Dependencies: none.

I'll tell you if the canary fails.

#2577's full mise run check passed, so it's confirmed ready for human review. Lint is clean, and all tests plus the Vogon canary pass with the branch merged onto current main.

#2582 is running its full check now and pushes once that passes; I'll report when it lands.

#2531 handles only part of it. Once each agent has finished a turn, it works; a commit made during an agent's first turn still gets the other agents' sessions attached.

Real binaries, three agents launched from main in worktrees X, Y and Z, with Y committing:

It's the same whether the agents edit the same relative path or different ones.

Why mid-turn still fails: Claude Code fires no Entire hook when an agent enters a worktree, so until an agent's first turn ends its session is still homed in main. For Y's commit:

• process ancestry correctly finds Y's session, and #2531 then re-homes it to Y;
• the older fallback ("no session is homed here, and all live sessions sit in one other worktree, so take those") also returns X's and Z's sessions from main;
• the two sets are unioned, and anything with pending content gets condensed.

Proposed fix: when process ancestry identifies the committing agent's session, skip the other-worktree fallback and union only sessions actually homed in the commit's worktree. The fallback would still apply when ancestry finds nothing, such as a human commit or Windows. Separately, the fallback could require a candidate's files to overlap the staged files, so a human commit in Y doesn't sweep in all three either.

Want me to implement that on #2531? The scenario script is ready to prove it.

Separately: #2582 is pushed (2166c2f852) with main merged in. Lint is clean, the full check passed, and GitHub shows it as mergeable. It's waiting only on approval.

API Error: Connection lost while your computer was asleep

The fix for your case is in #2531. It's committed as b2a4a2a6c5 and running the full check; I'll push once that passes.

The fix: when process ancestry identifies the agent making the commit, only sessions actually homed in that commit's worktree are added to it. The older fallback that pulled in sessions from another worktree is skipped. Before this, three agents launched from main were all still homed there during their first turn, so agent Y's mid-turn commit got X's and Z's sessions too.

Tests so far:

• Real binaries: agent Y's commit now links only Y. That's true mid-turn and after turns, and whether or not the agents edit the same file path. On main, all four cases linked X, Y and Z.
• Regression test: added one that fails on the old code and passes with the fix. The full strategy package and the worktree and linking integration tests pass.
• Still to run: the three-agent and follow-all scenarios on the final binary. The follow-all run makes sure no earlier behaviour broke.

Not covered, and why:

• A commit with no terminal and no agent ancestry (a GUI client or a script) still gets all three sessions. Entire treats a no-terminal commit as an agent commit, and post-commit condenses every session in the fallback. Fixing it means changing how those commits link, so it would be a separate change.
• A plain terminal commit by a person in Y during the first turn links nothing rather than the wrong sessions. That's a missed link, and main behaves the same.

Not yet: the push, the full check and CI are still pending.

Yes on the fresh binary, with one caveat. I rebuilt entire from the tree right after making the fix and ran all four three-agent cases, and every one linked only Y's session (main links X, Y and Z). That binary was built before the commit. The commit only adds the regression test and doc wording on top, so the code under test was the same.

The run still in progress repeats it on the final commit: a clean rebuild, the three-agent scenarios, and the earlier follow-all scenario to make sure nothing else regressed. It pushes only if the full check passes.

For human review, #2531 still needs:

1. The full check and final scenario reruns. Running now.
2. The push, then CI and the trail review. This is a new linking-behavior change, so the trail review should see it before a person does.

If all three come back clean, it's ready. I'll report when they finish.

Right, not yet. GitHub still has 3b5dadd863; the fix (b2a4a2a6c5) is only local.

The full check has just started (lint is running), and the push is chained after it and the scenario reruns. That's roughly 5 to 8 minutes. If you'd rather have it up now, I can push immediately and let CI run alongside, but the repo rule is to lint before any push.

#2531 is pushed (b2a4a2a6c5), and both descriptions are updated.

Final-commit testing, on a binary built fresh from the pushed commit:

• Full check passed, with lint clean.
• Three agents launched from main, with Y committing: Y's checkpoint holds only Y's session in all 4 cases (mid-turn and after a turn, same or different file paths). On main it held X, Y and Z every time.
• The follow-all scenario still passes, 17 of 17.

Descriptions:

• PR description: adds the new rule (an identified agent's commit links only its own session, plus sessions homed in that worktree) and the three-agent test. Two new follow-ups: commits with no terminal and no agent (GUI clients, scripts) still pick up every fallback candidate, and Antigravity sends no working directory.
• Trail 1378 description: rewritten. It still listed Gemini and predated the subagent following, Droid support and today's rule.

CI and the trail review are running on the new head. If both come back clean, #2531 is ready for human review; I'll report when they finish.

A reply to the report about X's session getting attached to Y:

Reproduced it: when several agents are spawned from main, each in its own worktree, they're all still homed in main until their first turn ends, so one agent's commit picked up the others' sessions. #2531 fixes it. An agent's commit now links only its own session, confirmed with real binaries for X/Y/Z. https://github.com/entireio/cli/pull/2531

CI and the trail review on #2531's new head are still running, so you may want to wait for them before posting.

Nothing is blocking. Open items across the PRs:

Waiting on others

• #2531 (1378): CI and the trail review are still running on b2a4a2a6c5. I'll handle any findings.
• #2582 (reset, 1420): mergeable and green; needs approval. I haven't re-checked its trail since the main merge (2166c2f852).
• #2577 (1416, skipped-hook carry-forward): ready; needs approval.
• #2574 (squash) and #2594 (main hotfix) are merged.

Known gaps we chose not to fix yet

1. Commits with no terminal and no agent (a GUI client or a script). They're treated as agent commits, so the fallback's sessions all condense into them. This is the remaining variant of the X-into-Y problem.
2. A person's terminal commit in a worktree during an agent's first turn links nothing. It's a missed link rather than a wrong one, and main behaves the same.
3. Agents with no working directory in their hooks: Cursor, OpenCode, the external-agent protocol, and now Antigravity. OpenCode and external agents are already on your separate trail. Antigravity is new since main merged it.
4. An interactive chooser for a person committing in a third worktree.
5. Two follow-ups #2577 itself calls out: linking the skipped-hook commit to its session, and a session whose only work was committed with hooks skipped.

Housekeeping

• Temporary worktrees in my scratchpad (sq, cf, hotfix) and the uncommitted SESSION-ATTACH-WORKTREES.md note in this worktree.

I'd take gap 1 next: it's the same misattribution class you just reported, and the scenario script already reproduces it.

#2531 has no code failures and no open findings. The re-run of the two failed jobs is in progress, and I'll confirm when it goes green.

• CI: test-codex-hooks failed because npm returned 404 for the newly published Codex 0.157.1 package, a registry delay rather than our code. The test job only rolls that result up, and every other check passes. "Entire Gates" is just the approvals gate.
• New trail finding (Medium, dismissed): it said the TodoWrite hook would mislabel files when an agent works in another worktree. That can't happen: the hook finds no subagent baseline there and skips the checkpoint. The real gap is that such subagents get no incremental TodoWrite checkpoints. Fixing it naively would pin the session to the parent worktree, so I've added it to the follow-up list.

The re-run passed, so #2531 is ready for human review.

All CI is green, including test-codex-hooks. The trail has no open findings. The only red check is "Entire Gates", and that's just the approvals gate waiting on a reviewer.

Both trail 1367 findings were real, and the fix is committed on #2521 but not pushed yet. It's in its full check now; the push and resolving both findings run automatically once the check passes, in about 5 minutes.

• The problem: the "checkpoint_remote is being ignored" message sanitized the repo name but not the reason text beside it. That reason can quote the owner taken from the same repo-controlled .entire/settings.json value. So a hostile repo could inject terminal escape sequences into entire status and entire enable output. The claim command, which also quotes the repo, had the same gap.
• The fix: the two shared message builders now sanitize every part themselves (repo, reason, destination and claim command), so both commands are covered in one place.
• Test: a new test feeds escape and control characters through both builders. It fails without the fix and passes with it.

Before the fix I brought the local branch up to date with Victor's main merge from today (9d32013197); it was the only commit I didn't have.

The sanitization fix is pushed to #2521 as cb5433ae6d, after a clean full check (lint 0 issues), and both findings are resolved. Trail 1367 has no open findings.

CI and the trail review will run on the new head; I haven't checked them yet, and can watch them if you want.

This does affect #2531. Nobody has opened a PR for #2612 yet. The reporter offered, and Soph (maintainer) agreed on the approach and asked that #2531 land after this fix.

The bug (#2612): since Codex 0.157, every Codex session on a machine runs inside one shared codex app-server daemon, so each session's recorded owner is that same daemon process.

• When session A commits, process ancestry matches every Codex session at the same depth.
• The tie is broken by most recent activity, so another session B, working in a different worktree, can win.
• B then gets condensed into A's checkpoint.

How it interacts with #2531:

• The linking set is no worse. It's A (homed where A commits) plus the wrong session B, the same as main.
• Re-homing can make it worse. #2531 re-homes the ancestry-identified session to the committing worktree. If ancestry wrongly picks B and B holds no pending work yet, B gets moved into A's worktree. B's own later hooks move it back because Codex sends cwd, but it's still wrong in between.
• Some of it already helps. B's hooks carry cwd, so B is homed in its own worktree. My latest rule ("identified agent: skip the fallback") doesn't touch this bug either way.

Soph's agreed fix, shared by commit linking and caller resolution (isNearerOwner / resolveCallerIdentity):

1. The nearest owner depth still wins.
2. At equal depth, the session named by CODEX_SESSION_ID (agent.CallerSessionCandidates()) wins.
3. Still tied with more than one live session: ancestry declines, and only worktree-matched sessions link.
4. Recency breaks the tie only when one candidate is live and the others have ended (by phase).

Soph wants the environment variable used only to break ties among sessions ancestry has already found, never to identify a session on its own. Her suggested test is two states sharing one Owner at equal depth.

Options:

1. I write it as a separate PR against main (roughly +150 lines including tests), so #2531 can land after it as Soph asked. This would take the reporter's offer away, so a comment on #2612 first would be polite.
2. Wait for the reporter's PR and keep #2531 on hold until it merges.
3. Fold it into #2531. Not recommended: #2531 is already large, and Soph asked for ordering, not merging.

I'd go with option 1. Want me to go ahead?

Two things, both small:

1. Stop #2531 from re-homing on a tied ancestry match. Today, if ancestry picks the wrong Codex session because of the shared daemon, #2531 can move that session into the committing worktree, and main never does that.

   • The guard: when several live sessions tie at the same depth, don't use the match for re-homing or for my new "identified agent skips the fallback" rule. Linking stays exactly as on main.
   • Then #2531 no longer makes #2612 worse, whichever PR lands first, and the contributor's fix won't need to touch #2531.
   • About +40 lines with a test (two sessions sharing one owner, as Soph suggested).

2. Note the ordering on the PR and trail: "lands after the #2612 fix", with a link to Soph's comment, so no reviewer merges it early.

Nothing else in #2531 is affected, and caller resolution isn't part of it.

Should I do both?

The formatting is back (paragraphs plus the bullet list). The code push is still waiting on the full check.

API Error: Can't reach the API server — check your internet or DNS (ENOTFOUND)

Both are done, and #2531 is pushed as dc39c62ea6. The first push attempt failed on a network error and the retry went through.

1. Guard: when another live session shares the matched session's owner process (the Codex daemon case in #2612), #2531 no longer treats that match as an identified agent. The session still links as it does on main, but it's never re-homed and never skips the fallback. findSessionByCommitAncestry and isNearerOwner are untouched, so the contributor's fix doesn't collide with this.
   • The new test (two live sessions sharing one owner) fails without the guard and passes with it.
   • The full check passed with lint clean.
   • The three-agent scenario still links only Y's session, and the follow-all scenario passes 17/17.
2. Merge order: the PR description has a merge-order note linking Soph's comment on #2612, and the trail description has the same note.

CI and the trail review are running on the new head, and I'll report when they finish.

CI and review are clean on #2531's new head (dc39c62ea6), and it's ready for review. It should merge only after the #2612 fix lands, as the PR notes.

• CI: 16 checks pass. The only failure is "Entire Gates", which is the approvals gate waiting on a reviewer.
• Trail: no open findings. The trail API no longer returns the gate breakdown, so I can't confirm the review gate itself passed, only that no findings are open.

The risk monitor scores #2531 at 67, "high blast radius". That's a fair description of what the PR is: it rewrites session state inside hooks that run on every commit. The review also found no defect: confidence is 84 and there are no open findings.

So there's no specific bug to fix here. The way to reduce the risk is to make a bad outcome cheap to catch and cheap to turn off. What I'd do:

1. Kill switch. Add a setting, read through the settings package, that turns off worktree following and hook-time re-homing and falls back to exactly main's behavior. If something goes wrong in the field, users or support can switch it off without a release. Turning it off only removes behavior, so it's safe to honor even from repo-committed settings. About +60 lines with a test.
2. An invariant test. One test runs every re-home path (own commit, turn boundary, turn end with no step, adopt) and checks nothing pending is lost or moved to the wrong place: files, task records, shadow steps and the carried prompt. This directly targets the "orphan pending content" concern.
3. Observability. Every re-home already logs at Info. I'd add from, to and the reason to one entire doctor line, so a wrong move is visible without reading logs.
4. Merge main again. The drift monitor flags an auth.go change as scope creep. It's the main hotfix I copied in, and merging current main removes it from the diff.
5. A "Risk and rollback" section in the PR, listing what can go wrong, the guards against each, and the kill switch.

Items 1 and 2 matter most. For item 1 you'd need to choose the setting's name and default; I'd call it follow_agent_worktree and default it to on. Should I do all five?

The invariant test (item 2) is committed on #2531. The full check is running, and I'll push once it passes.

• What it covers: the three hook-time re-home paths (own commit, turn boundary, turn end with no step) against every kind of pending work, 24 cases in all. A session moves only when nothing pending belongs to its old home, and a move never drops, changes or relocates the pending work itself.
• Mutation check: I disabled the pending-work guard, and 16 cases failed, so it would catch that regression.

I still need your call on recovery: a kill switch, a revert command, or both. My recommendation is the kill switch, a follow_agent_worktree setting that defaults to on. Moves that already happened can be corrected with the existing commands: entire session attach re-links a commit to the right session, and entire session adopt moves a session back.

The full check passed with lint clean, and the invariant test is pushed to #2531 as a43e2a438c.

The kill switch is still waiting on your call: kill switch, revert command, or both.

Kill switch, not a revert command. I'd add one setting, follow_agent_worktree (default on). Turning it off disables exactly the parts the monitors flag as risky: the process-wide chdir into the agent's worktree and all three re-home paths. The linking fixes stay on, since they only choose which sessions a commit links and never move state.

• Why no command: you can already fix a wrong result with entire session attach (re-link a commit) and entire session adopt (move a session back). A dedicated revert would need to record extra state to undo a move, which isn't worth it for a rare case.
• Trust: it's a normal setting, read through the settings package. Turning it off only removes behaviour, so honouring it even from a repo's committed .entire/settings.json can't be abused.
• Size: about +60 lines, with a test that "off" behaves like main: no move and no chdir.

The score changes are reviewer variance, not a real change. Between the two reviews the only change was the new test file:

• Security went from 26 to 38. The rationale lists the same surfaces as before (the chdir, cross-worktree I/O) and still says every path is correctly guarded.
• Risk went from 67 to 68, and confidence from 84 to 86.

These monitors routinely swing ±10–20 between heads with no code change. The kill switch does address the thing both rationales name, the in-hook chdir and state mutation, by making it switchable. That's the lever most likely to actually lower the scores.

Want me to add the kill switch?

Agreed. A switch users have to find and turn off doesn't help anyone; the feature should just be right. And if it's badly wrong in the field, reverting the PR in the next release is the real rollback, whether or not there's a flag.

So I'd skip the kill switch and put the effort where the risk actually is:

• Already done: the guards (pending work pins the home; hooks without cwd, tied daemon matches and other-tree baselines never move a session or claim files), the invariant test with its mutation check, and the real-hook scenarios.
• Still worth adding: a short "Risk and rollback" section in the PR description, so a reviewer sees the answer to the monitor's concern in one place:
  • what can go wrong, and the guard or test covering each case;
  • which behaviour is unchanged from main;
  • how to fix a wrong result: entire session attach re-links a commit, entire session adopt moves a session back;
  • rollback means reverting this PR, with no data migration needed. The new state fields are additive and ignored by older versions.

That needs no code. Want me to add it?

Yes, there was one gap, and it was a real regression: a worktree the session followed into, then deleted. Disposable agent worktrees are routinely removed once their work merges. Until now, the session stayed homed at the deleted path, later commits in main didn't link, and a shadow branch was left behind. On main this never happened, because sessions never moved.

• Fix: if a session's recorded home no longer exists, the next strong signal re-homes it, even when pending work was recorded there. That work stays in the session state untouched; nothing in a deleted worktree can be committed, so keeping the session there protected nothing.
• Proof:
  • the real-binary scenario now passes 5/5 (it failed 3 of 5 before);
  • a new unit test covers both re-home paths for a removed home;
  • the existing invariant test still passes.

I also rechecked the other plausible gaps and found nothing further:

• concurrent hooks for one session: the per-session lock covers them;
• older CLI versions reading the new state fields: the fields are additive and ignored;
• macOS symlinked temp paths and Windows path casing: both sides of the comparison come from the same resolver;
• agents that send no cwd: unchanged from main.

The full check and the full scenario suite (removed worktree, follow-all, three agents, skipped hook) are running, and I'll push when they pass. The skipped-hook scenario will still fail on this binary, because that fix is in #2577, not #2531.

The removed-worktree fix is pushed to #2531 as 2314660b77, after a clean full check (lint 0 issues).

CI and the trail review will run on the new head. I can also add the "Risk and rollback" section to the PR description, which would now mention the removed-worktree case, if you want it.

The finding's fix is committed on #2531 and not pushed yet. It's in its full check, and the push and resolving the finding run automatically once the check passes.

• The bug: if prompt.txt was condensed mid-turn and then refilled past its turn-start length, the offset landed mid-prompt and a fragment was carried to the other worktree.
• The fix: the offset is now used only when it sits on a prompt boundary; otherwise the whole file counts as this turn's. There's a unit test for it, and the follow integration tests pass.

On the risk score (now 74, "High"): there's nothing specific in it to fix. The rationale no longer names a defect, only that the change "could corrupt session linkage or lose pending work if guards fail". It scores what #2531 is: a large PR that rewrites session state inside git hooks.

• Evidence that doesn't help the score: we've added the invariant test, the mutation check, the removed-worktree fix, and the full set of real-binary scenarios. None of that moved it, and each push also adds more code for the reviewer to read.
• Evidence the scores are noisy: the same PR has scored 67, 68 and 74 across heads with no new defects found.

The real lever is size, by splitting #2531 into smaller PRs that are each easier to review:

1. Linking only: reservation at stamp time, the unlinked-commit notice, and the identified-agent rule. No state moves.
2. Hooks follow the working directory, plus re-homing: the chdir, the turn-boundary and own-commit re-homes, and the removed-home handling.
3. Subagents and cross-worktree baselines: baseline lookup, prompt carrying, pending-work location, and Droid support.

That's roughly half a day of work, including re-running all the checks and scenarios on each piece, and it means rewriting #2531's history, so it needs your force-push. Alternatively, keep it as one PR and add a "Risk and rollback" section so a reviewer can see the guards and tests up front. Which do you prefer?

The prompt-offset fix is pushed to #2531 as fbd8e75379, after a clean full check (lint 0 issues), and the finding is resolved.

Waiting on your call: split #2531 into three PRs (linking only / hooks follow the working directory and re-home / subagents and cross-worktree baselines), or keep it whole and add a "Risk and rollback" section to the description.

The High finding on #2531 is valid and the fix is committed, but it isn't pushed yet. It's running the full check, then pushes and resolves the finding automatically.

• The bug: the removed-worktree fix I made earlier let a session with uncommitted checkpoint steps move. Moving a session renames the key its shadow branch is looked up by, but not the branch itself, so those steps would become unreachable.
• The fix: a removed worktree now releases a session only for pending files and task records. Checkpoint steps still hold it, and that case is logged instead of lost silently.
• What it costs: the common flow is unaffected, since the work is committed (which clears the steps), merged, and then the worktree is removed. The real-binary scenario still passes 5/5, and the updated test covers both cases. The only session still stuck is one whose worktree was deleted with uncommitted work, which is now logged.

This one matters for the risk question: these are the bugs the monitor was worried about. Two of the last three findings were in code added this week while addressing risk, which supports splitting #2531 so each piece gets a closer review.

The High finding's fix is pushed to #2531 as 11e72b558a, after a clean full check (lint 0 issues), and the finding is resolved.

The split question is still open: split #2531 into three PRs, or keep it whole and add a "Risk and rollback" section?

Yes, tested on a binary built fresh from the pushed head (11e72b558a), and everything passes. The session really did have one checkpoint step in the new case (an earlier printout showed - only because I queried the wrong JSON field name).

Why the risk is still 62 (down from 74): the latest rationale names no defect. It says the hook and re-home logic "could misattribute work or orphan shadow-branch steps", and that "extensive test coverage mitigates critical failure modes". That's a judgement about what kind of change this is (git hooks rewriting session state), not about a known bug. Every concrete issue the reviews raised has been fixed or explained, and none are open. The score has moved 67 → 68 → 74 → 62 across heads without tracking defects, so I'd read it as a rough band rather than a measurement.

Two things would bring it down for real:

1. Splitting #2531 into three smaller PRs, so each one touches less of this surface.
2. Time in the field: a nightly release with the new warning logs to watch.

Adding more guards to the same PR mostly adds code for the reviewer to weigh.

Yes, it's fine for human review. I'd go ahead with two caveats.

Why I'm comfortable:

• Every concrete defect raised has been fixed with a test, or explained where the premise didn't hold.
• The real-binary scenarios cover the flows people actually hit: moving into worktrees, subagents, several agents from one checkout, and removed worktrees.
• The invariant test pins the core promise: a re-home never loses or corrupts pending work.

The caveats:

1. The last two real bugs were in code I added this week (removed-home handling and the prompt offset), and the trail review caught them, not my tests. This surface is subtle, and a human reviewer should look hardest at session_identity.go, the re-home guards and the baseline lookup.
2. Merge after the #2612 fix, as Soph asked. Until then the daemon guard keeps #2531 from making that bug worse.

Also check the trail review on 11e72b558a before you request review; it hadn't finished when I last looked. If it's clean, request review.

I wouldn't split it now. Splitting helps the risk score and eases review, but it wouldn't find any new bugs, and after this many rounds the value is in a person reading it. If the reviewer finds it too big to review, split it then.

Nothing else has merged besides #2521 (checkpoint_remote). #2531 is still open, waiting on review.

Ours, ready for review (all CI green except the approvals gate, no open trail findings, no merge conflicts with main):

Related open PRs from others that affect ours:

• #2621 (pletinsky, the #2612 fix):
  • It's up, but its CI hasn't run. It's a fork PR, so a maintainer probably has to approve the workflow run.
  • It conflicts with #2531 in session_identity.go and its test, which is expected since both change the same linking code.
  • Once it lands I'll merge it into #2531. My shared-owner guard then becomes redundant, and I can drop it.
• #2486 (Soph, "Capture a turn against the worktree the agent worked in"): it solves the same problem as #2531's cwd following, and conflicts with it in lifecycle.go. Whichever lands second is mostly redundant, so it's worth agreeing with Soph which one goes in.
• #1859 ("surface ambiguous-worktree warning"): #2531's unlinked-commit notice covers this, and only when the commit holds a candidate's work. It could probably be closed once #2531 merges.

Also related but not blocking:

• #2332 (Soph: adopt refuses a session that isn't its caller);
• #1777 (auto-adopt across git common dirs);
• #1959 (yours, session binding across repos, stale since 2026-09-12).

Suggested next steps:

1. Approve #2621's CI run.
2. Settle #2531 vs #2486 with Soph.
3. Request review on #2582 and #2577 now; they don't depend on anything.

The nine real findings on trail 1378 are fixed and committed on #2531, in two commits (d4065f88f6 and 86806f674c). Not pushed yet: the full check and every real-binary scenario are running now, and the push only happens after they pass. Then I'll resolve the nine and dismiss the other three with reasons.

• H1, a session pulled back out of its worktree: confirmed with the real binary. The previous head moved the session back to the launch checkout, and the new head keeps it in the worktree.
• H2, a leftover reservation reusing a checkpoint ID: post-commit now releases the reservation for any session it didn't condense. A condensation that has already started writing keeps it, so interrupted retries still work.
• Mediums and Lows:
  • the payload cwd is now resolved through git, honouring safe.directory and ownership;
  • path comparison resolves symlinks, through one shared helper;
  • the moved logger is flushed and closed;
  • "capture degraded" now covers every case where new-file detection is off;
  • the turn pointer is cleared at turn end;
  • the dead code is gone.

The unit and integration suites all pass.

One judgement call to flag: the cwd fix needed a new entry in the git-metadata guard ledger, with a reason. It's the same pattern the ledger already allows for adopt and dispatch, which also resolve a directory someone else named.

I fixed the lint issue: I removed an unneeded //nolint, amended it into the unpushed commit, and recreated the deleted three-agents scenario script. The full check and every scenario are running now. Nothing is pushed yet: I'll push once they pass, then resolve the nine findings and dismiss the other three.

Scenarios all pass and lint is clean, but four PrePromptState unit tests fail. I didn't run the full cli package after the turn-pointer change, so checking what broke.

mise run check and the real-binary scenarios are running in the background now. Nothing is pushed yet.

The earlier run had four failing TestPrePromptState_* tests. They broke because the cleanup at the end of a turn also clears the session's record of which worktree the turn was in, and that update fails in test folders that aren't git repositories. I made that step best-effort: a failure is now logged at debug level instead of returned. A leftover record only makes the next turn check one extra worktree first. With that change, the cli package tests pass. I folded the fix into the last commit, so it's now 7c0adea7a3.

Once check and the scenarios pass:

• Push: update #2531.
• Resolve (9): mark the other nine trail 1378 findings resolved.
• Dismiss (3): each with its reason:
  • Prompt carried twice: it can't recur, because the old baseline is removed and the next turn records a fresh starting point.
  • Announcement filter: filtering earlier would suppress legitimate Claude notices.
  • Untracked-file scan: the rare untracked-file scan during re-homing is a follow-up.

Nothing is pushed yet. Lint is clean and the full test suite is running now. The three-agent, cd-worktree, removed-worktree and follow-all scenarios run on a fresh build after that.

The four TestPrePromptState_* tests that failed last run now pass in the cli package. I made clearing the turn's worktree record best-effort, so it no longer fails in test folders that aren't git repos. That fix is folded into the last commit, now 7c0adea7a3.

Once the tests and scenarios pass, I'll push #2531, resolve 9 of the 12 findings on trail 1378, and dismiss the other 3 with reasons. I'm watching the run and will tell you when it finishes.

Check passed; scenarios running.

#2531 is pushed as 7c0adea7a3, after mise run check passed and every real-binary scenario passed on a fresh build.

• Three agents (X, Y, Z): only Y's session is attached to Y's commit, in all 4 variants.
• cd-worktree: 3/3.
• Removed-worktree: 9/9.
• Follow-all: 17/17.

On trail 1378, all 12 findings are closed: I resolved the 9 I fixed and dismissed the other 3 with reasons:

• Prompt carried into two worktrees: can't repeat, because the old copy is deleted and the next turn records a fresh starting point.
• Extra message on the ambiguous path: filtering it earlier would also hide notices Claude should see.
• Untracked-file scan under the lock: it only runs when a session actually moves worktrees, which is rare. Moving it out of the lock is a follow-up.

CI on the PR is still running (one check passed, the rest pending). The trail review of this push hasn't landed yet. I'll check CI and any new findings once it does.

The Entire Gates check on #2531 failed on one new medium finding. I've fixed it in a new commit, but it isn't pushed yet: mise run check is still running.

All the other CI checks passed (16), with one skipped. The finding was a missing --no-optional-locks on the git rev-parse call that looks up a worktree's root. That command doesn't lock anything, but adding the flag is a one-line change and matches the rule for other git calls in hooks. The follow and guard tests pass with it.

When check passes, the push and resolving the finding run automatically. I'll then watch for the gate and any new findings.

Nothing is pushed yet. mise run check is still running on the new commit. When it passes, the push and resolving the finding happen automatically, and I'll tell you then.

Pushed: #2531 is now at 1206c8db8e, after mise run check passed with lint clean. The --no-optional-locks finding is marked resolved on trail 1378. The gate and trail review haven't re-run on this push yet, so I'll check for new findings once they do.

#2531 isn't ready for human review yet. The last push got a new High finding, and I've fixed it locally but not pushed.

• The finding: when linking a commit to sessions, the code compared worktree paths with plain ==. A session recorded under a symlink or with a trailing slash would be missed. That line already exists on main, but this PR relies on it more, so it's worth fixing now.
• The fix: it now uses paths.SameDir. A new test covers a symlinked path and a trailing slash; it failed before the fix and passes after. The strategy package tests pass.
• Running now: mise run check and the four real-binary scenarios on a fresh build. If both pass, it pushes and marks the finding resolved automatically.

Once that push lands, it's ready for human review when CI is green, the gate passes and no new findings come back. The risk score is 72. Like the earlier ones, it reflects that the PR changes hooks and session state, not a known bug.

Pushed: #2531 is now at 6341859425, and I've marked the path-matching finding resolved on the trail.

Before the push, mise run check passed and lint was clean. All real-binary scenarios passed on a fresh build:

• Three agents (X, Y, Z): only Y's session is attached to Y's commit, in all 4 variants.
• cd-worktree: 3/3.
• removed-worktree: 9/9.
• follow-all: 17/17.

CI and the trail review for this head are still running, and I'm watching both. It's ready for human review once they're green with no new findings. I'll tell you when that happens, or fix anything new that comes up.

No, 1378 (#2531) doesn't do this; it doesn't touch settings loading. Settings are read from each worktree's own .entire/. Only a small set of clone-local preferences (review profiles, trails cache) live in the shared git directory, so a new worktree doesn't get the main tree's settings.local.json.

I reproduced it with the branch binary: I ran entire enable --local in main, then git worktree add.

• The new worktree: has no settings.local.json, and entire status there says "not set up".
• Agent launched in the worktree: no session is recorded, and its commit gets no checkpoint.
• Agent started in main that moves into the worktree (the case #2531 follows): it stays tied to main and its commit gets no checkpoint.

In this setup the failure is lost checkpoints, not attachment to the wrong session. I didn't see "unknown agent" either. Those symptoms probably need a different setup, such as a committed settings.json plus local agent settings, or another live session in main. If you have the report's exact setup, I can reproduce that too.

I'd fix it in a separate PR, not #2531, which is already large and nearly through review. There are two ways to fix it:

1. Fallback (recommended): when a linked worktree has no settings.local.json, read the main worktree's copy. It belongs to the same clone and developer, so it still counts as developer-owned settings for the security checks that depend on that. It stays live and needs no copying or hooks.
2. Copy on create: copy the file when the worktree is created. The only trigger is the post-checkout hook, and a copy goes stale when you change settings in main.

Want me to open a separate PR for option 1?

#2531 is ready for human review. On head 6341859425, 16 CI checks passed with 1 skipped, and trail 1378 has no open findings. I tested this head on a fresh binary, and every scenario passed.

The one red check is Entire Gates. It fails on the risk score (now 78, up from 72), not on a finding. The reviewer's reasons are the kind of change this is:

• it touches git hooks and changes the working directory during hooks;
• it moves sessions between worktrees;
• it reserves checkpoint IDs.

Tests already cover the two concrete worries it names. Re-homing never strands uncommitted work, and a reserved checkpoint ID is released when the commit doesn't use it. Security went from 26 to 45 on the same code. Its only reason is that the agent-supplied directory reaches the working-directory change and a git call, which the rationale itself says is validated through git and limited to worktrees of the same repository. These scores have swung about ±20 between heads before, and more fix rounds won't lower the score. A careful human review of the hook and re-homing paths is what it's asking for.

The worktree settings.local.json fix is still waiting on your answer: should I open it as a separate PR with the fallback to the main worktree's copy?

The last check on trail 1378 found no open findings, so #2531 is ready for human review.

The settings.local.json worktree fix is still waiting on your answer.

#2573 and #2574 are merged. Three of ours are open and ready for human review, and none has a human reviewer yet: only cli-maintainers is requested. Entire Gates is red on all three because of the risk score, not open findings.

Want me to refresh #2577 and #2582 against main and check their findings?

Trail 1420 (#2582, redone commits keep their trailers) now has a description, based on the PR body: problem, fix rules, test results and follow-up.

Its only failing gate is approvals (no reviewer yet). CI checks and findings both pass.

The PR body on #2582 still says "Stacked on #2574", but #2574 has merged. Want me to update that line too?

I updated #2582's description. The old "Stacked on #2574" line now reads:

Builds on #2574 (squash, merged), which added the post-commit fix both rely on: condense only into the trailer that has no checkpoint yet. This diff is the redo work only.

I checked that last sentence: main was merged into the branch after #2574 landed, so the PR's diff (+1175/−2 across 9 files) contains only the redo work.

Yes, I just retested both with freshly built binaries against real hooks, and both work.

I built three binaries for each PR: current main, the PR head, and the PR head merged locally with main (nothing pushed). Both branches are 105 commits behind main, but main merges into each without conflicts.

#2582, redone commits keep their trailers. One session made two commits, each with a checkpoint trailer, and then they were redone:

When the redone content differs from the original, the commit correctly gets no trailer on all three builds.

#2577, skipped-hook commit. A turn's file was committed with every git hook skipped, then two normal commits followed:

When the file is edited again after the skipped commit, it is still carried forward on all three builds, which is correct.

Neither branch has main merged in yet. Want me to merge main into both, run mise run check, and push?

All 15 of Stefan's adversarial tests from before the split (4a5df627d0) still exist with identical assertions, and all 15 pass. Each of the 10 that were meant to catch a bug fails on the code from before the fixes.

• The wider redo, squash and rewrite set (77 tests, unit plus integration) passes on both the PR head and the PR merged with main.
• Where they live now: the redo tests are in #2582 (manual_commit_redo_adversarial_test.go, integration_test/redo_adversarial_test.go). The squash tests are on main.
• One caveat: the redo unit tests can't run against current main to show them failing there. They use test helpers that were added with the fix, so they don't compile without it. Stefan's original commit is the before-fix baseline instead.

Together with the fresh-binary runs from earlier, #2582 holds up. It's still 105 commits behind main but merges cleanly. Want me to merge main in, run mise run check, and push?
