Session Review and Smoke Testing Fixes

I’ll use Entire’s review workflow so the audit includes the Claude session’s recorded intent, the three smoke-test trails, and the current committed plus uncommitted diff. I’ll keep this read-only and report findings by severity with concrete file/line evidence.

★ Insight ─────────────────────────────────────

• In this repo, a trustworthy review needs both the Git diff and checkpoint/session context; either alone can misclassify intentional behavior as a regression.
• The uncommitted smoke-test fixes are especially important because they may close gaps exposed after the branch’s recorded checkpoints. ─────────────────────────────────────────────────

Entire Review:

I’m now resolving the exact branch scope and the CLI’s current session/trail commands before reading code. The specific Claude session ID will be treated as the primary intent record; branch checkpoints and the active session will supplement it.

The first scope calculation exposed a review hazard: the branch is 14 commits behind/ahead relative to today’s origin/main, so a simple endpoint diff reports 102 files and includes unrelated upstream drift. I’m separating the session-authored commits from base movement before judging the implementation.

★ Insight ─────────────────────────────────────

• A two-dot endpoint diff against a moving mainline can make upstream deletions look like branch deletions; the merge base and left/right counts reveal whether that scope is real.
• Here, the Claude session’s metadata narrows the likely implementation surface to lifecycle/worktree identity code and smoke-test evidence, which is much more precise than blindly reviewing all 102 apparent files. ─────────────────────────────────────────────────

I’ve confirmed the reviewable branch delta is 27 files (+1,015/−35), not the misleading 102-file endpoint diff. The only uncommitted item is the 380-line investigation/smoke-test notebook; there are no uncommitted code changes.

I’m checking two things now: whether the recent smoke-test fixes actually close their stated failure modes, and whether the branch remains compatible with the 79 mainline commits added since its merge base.

The recent fixes are internally consistent: the target-worktree enablement check happens before chdir, Copilot now propagates cwd, and the reservation is created only after the trailer write succeeds. I also found the smoke notebook is a chronology, not commit-ready documentation—it contains several superseded heads and status claims.

★ Insight ─────────────────────────────────────

• The reservation fix closes a subtle two-hook race: prepare-commit-msg chooses the session, while post-commit may run without the same ancestry. Persisting the stamped checkpoint ID bridges that identity gap.
• Re-homing deliberately happens only after successful condensation and only when the old home has no pending content; that prevents “moving” a session while leaving its shadow state behind. ─────────────────────────────────────────────────

I’ve finished reconstructing the Claude session and validating the current branch. I found one concrete lifecycle gap in the worktree-follow implementation and one hook-safety issue; I’m now checking the two companion branches so the review covers all three smoke-test fixes rather than treating the session in isolation.

The trailer-preservation branch has a second concrete edge case: its redo detector represents staged changes only as index blobs. A staged deletion has no index blob, so resetting and recommitting a deletion drops the original checkpoint trailer—the exact class of history rewrite this branch is meant to preserve. I’m reproducing that Git state directly before I finalize the severity and recommendations.

Entire Review:

I reviewed Claude session 26e94612-1225-4236-8ee1-9f35de82f710, the current branch, both companion branches, and the uncommitted work. The implementation is directionally sound, but the session’s final “all three are ready” conclusion is premature: I found 2 high-, 2 medium-, and 1 low-severity issue.

Findings

High — dead idle sessions can still be deleted before recovery

In trail 1413, isOrphanedSessionState preserves a live idle session but explicitly deletes one whose owner has exited. The accompanying test codifies that deletion.

That races against finalizeExitedSessions, whose documented responsibility is to mark dead-owner sessions ended and eagerly condense their pending transcript. If another worktree’s commit hook calls listAllSessionStates first, it clears the state file, losing the transcript and preventing the recovery sweep.

Suggested fix: never orphan-delete a non-ended idle state. Let the dead-owner finalizer or normal stale-state expiry own its lifecycle. Add a regression test with a dead-owner, transcript-bearing idle session where another worktree’s hook runs before the sweep.

High — subagent lifecycle hooks do not follow the agent’s worktree

The dispatcher calls followAgentWorkingDirectory for every event at lifecycle.go, but several parsers discard the payload CWD:

• Claude’s SubagentStop struct explicitly ignores cwd at types.go, and its event omits it at lifecycle.go.
• Codex already parses CWD in both subagent payload structs, but drops it when constructing events at lifecycle.go and lifecycle.go.

Subagent start/end processing captures baselines and normalizes files against the process worktree at lifecycle.go. After an agent enters another worktree, these hooks can therefore record or filter files against the launch worktree, silently losing attribution.

Suggested fix: populate Event.CWD for Claude SubagentStop and Codex SubagentStart/SubagentStop. Add parser tests plus a background-subagent integration test that finishes after moving worktrees.

Medium — reset/redo loses trailers for deleted files

Trail 1414’s stagedBlobs only records staged paths that still have index entries. Staged deletions have no index blob, so a reset-and-redo of a deletion never matches the dropped commit and loses its checkpoint trailer.

I reproduced the underlying Git state:

Suggested fix: model staged changes as present/deleted rather than only path → blob. A deletion matches when the path is staged as deleted and is absent from ORIG_HEAD’s tree. Add soft and mixed reset tests for deletion-only commits.

Medium — target-worktree settings probe inherits hook repository overrides

The new target enablement check calls settings.go:

It does not set gitrepo.EnvWithoutRepoOverrides(). This violates the repository’s hook-safety contract: GIT_DIR/GIT_WORK_TREE can override the target and cause clone preferences to be resolved from the wrong repository.

Suggested fix: preferably use gitrepo.ResolveWorktreeMetadata(worktreeRoot).CommonDir; otherwise scrub repository override variables on the subprocess. Add a hostile-environment regression test.

Low — the uncommitted document is a stale working log

The only uncommitted change is SESSION-ATTACH-WORKTREES.md. It is useful as a scratchpad but not commit-ready:

• The title and symptom still describe session attach as always required.
• Line 10 names an obsolete base.
• The status section successively claims “not pushed” and several outdated PR heads.
• It stops before the final ORIG_HEAD correction and the current heads.

I would either leave it untracked or rewrite it into a short final retrospective before committing.

Verification

• Current branch unit tests: 11,883 passed, 9 skipped
• Integration tests: 662 passed, 4 skipped
• git diff --check: clean
• Current branch is 79 upstream commits behind origin/main, but the merge-tree check found no textual conflicts.
• No real-agent E2E was rerun during this review; the Claude session already performed the requested Codex smoke tests.
• All three PRs were mergeable and ordinary CI/CodeQL checks were green. They remained review-blocked with Entire Gates red. I could not independently inspect Entire findings or current risk scores because the local Entire CLI is not authenticated, so the exact gate reason is not fully verified.

★ Insight ───────────────────────────────────── The recurring design issue is ownership of cleanup: hook-time listing, dead-owner finalization, and stale expiry must not all be allowed to destroy the same state. Likewise, worktree following only works as a system invariant when every event parser preserves CWD—one omitted lifecycle event is enough to silently return capture to the launch tree. ─────────────────────────────────────────────────

No files were changed. Would you like me to create a fix plan for these findings?

Entire Review:

You’re right—the relevant question is not whether the session said the smoke-test gaps were fixed, but whether those exact scenarios work at the recorded commit heads. I’ll reproduce the smoke tests against each of the three branches, including the edge cases the follow-up work claimed to cover, and verify which fixes were actually committed versus only discussed or left in the session workspace.

I’m using the systematic-debugging and Entire review workflows because this now requires reproducing behavior at the exact branch heads before drawing conclusions.

The branch inspection already confirms the follow-up work was committed, but “committed” is not the same as “correct.” I’m going to run isolated reproductions at heads 79d1d794, 0f2dcb1a, and b2c8e5a8, outside your working tree, so the results cannot be masked by today’s branch or by the untracked notebook.

★ Insight ───────────────────────────────────── These three fixes cross process boundaries: agent payload → lifecycle event → worktree state, and Git rewrite state → commit-message trailer. Unit tests can pass while the boundary wiring is wrong, so the useful smoke test must exercise the serialized payload or real Git index/reflog state—not just call the final helper with idealized inputs. ─────────────────────────────────────────────────

Two reproductions are now concrete at the committed heads:

• Trail 1414: a real staged deletion after reset --soft leaves the new message without the prior checkpoint trailer.
• Trail 1378: a real Codex SubagentStart payload naming the linked worktree writes pre-task state and session ownership into the launch worktree.

I’m checking trail 1413 the same way now: create an idle session whose recorded owner exits, then let a later hook list the shared store and observe whether it is finalized or simply deleted.

You were right. I tested the committed branch heads directly, and all three still fail meaningful smoke scenarios.

Reproduction results

Trail 1378 — fails subagent worktree following

Tested head 79d1d794.

I sent the built binary a real Codex SubagentStart payload while:

• The hook process started in the parent worktree.
• The payload’s cwd pointed to a linked worktree.
• Entire was enabled in both worktrees.

Observed:

Expected both to use cwd-target.

Root cause: Codex parses cwd in the raw subagent payload but does not copy it into Event.CWD. Claude SubagentStop has the same gap.

Trail 1413 — deletes an exited idle session

Tested head 0f2dcb1a.

I created a real Codex session, completed a read-only turn, confirmed it was idle with one turn and no checkpoint, allowed the hook’s recorded owner process to exit, and then ran an unrelated commit’s post-commit hook.

Before:

After:

The state was deleted rather than finalized and condensed. So the live-owner smoke case was fixed, but the known-dead-owner path can still destroy recoverable session context before the detached finalizer sees it.

Trail 1414 — loses trailers for redone deletions

Tested head b2c8e5a8.

I made a checkpoint-linked commit that deleted gone.txt, ran git reset --soft HEAD~1, and passed the resulting staged deletion through the branch’s actual prepare-commit-msg hook.

Observed:

Expected the original Entire-Checkpoint trailer to be inherited.

Root cause: the redo detector only represents staged files that have index blobs. A staged deletion has no index entry, so it disappears from the comparison.

Were the fixes committed?

Yes—the session’s follow-up fixes are present at the three remote branch heads:

• 79d1d794 — trail 1378
• 0f2dcb1a — trail 1413
• b2c8e5a8 — trail 1414

But they only fix the smoke-tested happy paths, not the adjacent lifecycle cases above.

The current worktree has no uncommitted code fixes. Its only uncommitted file remains:

So none of these remaining fixes are sitting locally waiting to be committed.

★ Insight ───────────────────────────────────── The original smoke tests each proved one successful path, but the missing cases occur one boundary earlier: subagent payload conversion, dead-owner cleanup ownership, and Git’s representation of deletions. Testing through the actual hook binaries exposed those gaps immediately, while the helper-level tests remained green. ─────────────────────────────────────────────────

No repository files were changed. The next step should be to add these three reproductions as failing tests before modifying the implementations.

I’ll turn the three black-box failures into regression tests first, confirm each test fails at its branch head, then make the smallest branch-specific fix and rerun the relevant suites. Because the fixes live on three independent branches, I’ll keep them isolated and won’t commit or push anything unless you separately authorize that.

I’m using the brainstorming, planning, TDD, and parallel-work workflows here: they require the failing tests to establish each contract before implementation, and they keep the three branch histories from being mixed together.

I’ll keep each regression and fix on its existing branch:

• Trail 1378: propagate subagent CWD and test real payload-to-worktree behavior.
• Trail 1413: preserve dead-owner idle state for finalization, with the reproduced hook-order race test.
• Trail 1414: represent staged deletions in redo detection, with reset-and-recommit deletion coverage.

Each will follow red → minimal fix → green → relevant branch suite. No commits or pushes yet.

Should I proceed with the fixes remaining separated across those three existing branches?

The separation is approved. I’ll now set up isolated worktrees for the two companion branches, keep trail 1378 in the current worktree, and run each regression through a strict red/green cycle. The existing untracked notebook will remain untouched.

★ Insight ───────────────────────────────────── The minimal fixes belong at the data-loss boundaries: preserve cwd while decoding agent payloads, preserve non-ended state until the finalizer owns it, and preserve “deleted” as an explicit staged state rather than treating absence as “not changed.” That keeps each correction local instead of adding compensating logic downstream. ─────────────────────────────────────────────────

The two companion branches already have clean, isolated worktrees left by the Claude session, so I’m reusing them instead of creating new ones. I’m dispatching one focused TDD task per branch now; each agent is constrained to its assigned worktree and may not commit, push, or touch the notebook.

The three regression tasks are running independently. The red criteria are explicit: each new test must fail for the reproduced reason—not from setup errors—before production code changes are accepted. After they return, I’ll inspect every diff myself and rerun the tests from the parent session rather than relying on agent summaries.

Trail 1378’s first red/green cycle is complete: the parser regressions failed with empty CWDs, then passed after propagating CWD for Codex start/stop and Claude stop. The hostile Git-environment test also failed before the settings fix and now passes using explicit worktree metadata. I’ve reviewed that diff; it is small and matches the reproduced causes. The other two branches are still running their relevant suites.

All three branches now have demonstrated red→green fixes, and I’ve inspected the diffs. Before the full repository checks, I’m running independent code-quality reviews on each branch; this is specifically to catch false-positive matching, lifecycle regressions, or tests that only prove helper behavior instead of the real contract.

The fixed CWD and deletion-redo binaries now pass the exact black-box scenarios that previously failed. The idle-session process test no longer gives a simple “state survives” signal because the real CLI’s detached exited-owner sweeper can legitimately finalize and remove the state between commands; I’m checking checkpoint materialization to distinguish correct finalization from the original destructive orphan cleanup rather than treating disappearance alone as failure. An independent reviewer also caught one stale source-guard ledger entry in trail 1378, which is being corrected now.

Independent review found and prevented one additional regression in trail 1414: newline-delimited git diff --name-only can quote unusual filenames, which the new code could misread as deletions and falsely inherit a checkpoint. That branch is now adding NUL-delimited path handling and a negative regression test. The idle-session review found only stale comments, which are corrected; trail 1378’s stale metadata-guard ledger is also corrected.

The fixes and review follow-ups are in place. I’m at the final verification gate now: mise run check on each branch, which covers formatting, lint, unit, integration, and deterministic canary tests. I’ll also rerun the exact hook-level reproductions afterward where the full suite cannot prove process-boundary behavior.

The first full-check attempt exposed only tooling contention: three concurrent golangci-lint processes refuse to coexist, so trail 1378 and 1414 stopped before completion while trail 1413 continued. This is not a code failure. I’m letting the active check finish, then rerunning the other two sequentially as the repository tooling requires.

Trail 1413’s full race-enabled CI suite is still running without emitting failures; lint and formatting already passed. The duration is expected for this repository’s -race integration suite. I’m continuing to wait rather than substituting a partial test run.

Trail 1413 has now passed the complete required check: formatting, lint, all race-enabled unit/integration tests, and both deterministic E2E canaries. Trail 1378 has formatting and lint green and is currently in the race-enabled test phase; no failures have appeared.

Trail 1378’s full check remains active in the large CLI race suite, again with no failure output. This branch also includes the source-guard correction caught by review, so the running check is validating both the behavior fix and the repository’s enforcement ledger together.

Trail 1378 has passed its complete check, including 56 Vogon scenarios and 4 external-agent canaries. Trail 1414 is now the final branch under full verification; formatting and lint are already green, with the race-enabled test suite running.

Trail 1414 remains in the long race-enabled CLI suite with no failure output. Its focused redo tests, full strategy package, unusual-filename regression, and lint have already passed; this final run is the repository-wide guard against shared getStagedFiles regressions.

All three requested regressions now pass full checks and the exact hook-level reproductions. One reviewer identified a remaining pre-existing edge in trail 1414—pure rename redos may not inherit trailers because go-git reports rename paths differently. Since that trail’s promise is broader than only additions/modifications/deletions, I’m verifying this before I call the branch complete.

The pure-rename investigation is taking longer than the earlier unit cases, which usually means it reached broader strategy verification rather than failing at setup. I’m waiting for its red/green evidence; I won’t treat the prior full checks as final if this adds another branch change.

The final review uncovered one more subtle case on the squash/redo branch: a commit that is purely renamed may have no ordinary file stats, so trailer inheritance now compares typed tree changes instead. I’ve added that regression and am rerunning the complete branch gate after this last change.

★ Insight ─────────────────────────────────────

• Trailer inheritance needs to distinguish three index states: a blob value, an explicit deletion, and no staged entry. Collapsing deletion into an empty hash caused the original gap.
• Git’s human-readable path output is unsafe for machine matching because quoting can turn a real non-ASCII filename into a different string; NUL-delimited output avoids that ambiguity.
• Tree changes are a better source than commit stats for redo detection because they preserve deletes and pure renames, not just line-counted edits. ─────────────────────────────────────────────────

The post-change gate is progressing normally: formatting and every lint layer are clean, including golangci-lint with zero issues. The race-enabled CI test suite is still running, and the independent reviewer is checking the final tree-diff logic rather than only the newly added test.

The independent re-review found two real edge cases, so I’m not treating the current green run as completion: directory/gitlink entries can masquerade as “absent,” and a partially staged rename can match only its deleted source. I’m adding focused failing tests for both before adjusting the matcher, then I’ll restart the full gate from the resulting tree.

★ Insight ─────────────────────────────────────

• In go-git, Tree.File(path) answers “is this a regular file?” rather than the stricter “does this path exist?” question; FindEntry is required to distinguish absence from directories and gitlinks.
• A rename has two meaningful endpoints. Partial staging can reproduce the destination addition or the source deletion independently, so matching only To.Name narrows the established “any redone part” behavior. ─────────────────────────────────────────────────

The other two branch diffs remain clean under git diff --check, and their scopes are unchanged. The redo branch fix is still in the test-first cycle; once its two new regressions fail for the intended reasons and pass with the matcher change, I’ll rerun the complete repository check rather than relying on the interrupted pre-fix run.

Both new tests produced the intended RED failures, and the matcher change now makes all four critical redo cases pass: deletion, pure rename, source-only partial rename, and the file-to-directory negative case. The key correction is that absence now means FindEntry returned ErrEntryNotFound—not merely “this path is not a regular file.”

I’m running the complete check from this exact tree now, and I’ve sent the amended matcher back through independent review once more.

The final reviewer caught one last deletion variant: if deleting the last file also removes its parent directory from the tree, go-git reports ErrDirectoryNotFound while resolving the child. Semantically the exact child path is still absent, so the matcher must accept both leaf absence and missing/non-directory ancestors while continuing to reject an existing directory or gitlink at the exact path.

I’m adding that focused regression now; the currently running full gate will be restarted afterward because this change invalidates it.

The nested deletion regression failed before the change and now passes with the complete PrepareCommitMsg redo test set. The matcher accepts only the two go-git lookup errors that establish exact-path absence—ErrEntryNotFound and ErrDirectoryNotFound—while an existing tree or gitlink still yields an entry and cannot be mistaken for deletion.

★ Insight ─────────────────────────────────────

• “Path absent” in a Git tree is hierarchical: the leaf may be missing, or an ancestor may be missing/not a directory. Both mean the full path is absent.
• Explicit error classification matters here; treating every lookup error as absence would silently convert corrupt-object or storage failures into false trailer inheritance. ─────────────────────────────────────────────────

One more path-shape case remains: an ancestor can exist in ORIG_HEAD but be a file or symlink, making a nested child logically absent even though go-git surfaces a lower-level type error. I’m replacing the one-shot lookup with component-by-component tree traversal so “non-directory ancestor” is classified as absence before go-git tries to open it as a tree; genuine object-read errors will still fail closed.

The component-wise traversal is now in place and the full redo test family is green. The complete repository check is still running; format and the early CI packages have passed, with the race suite and remaining lint work continuing.

The full gate found no behavioral failure, but lint correctly rejected two raw go-git errors from the new helper. I’m wrapping those external-package errors with the failing path component, then rerunning the entire check; this preserves the fail-closed behavior while making diagnostics actionable.

The lint blocker is resolved: golangci-lint now reports zero issues, and the race-enabled suite is continuing through the larger CLI packages. The independent reviewer also confirmed there are no remaining reproducible correctness issues in the redo matcher.

All final gates now pass on the redo branch: full race-enabled CI, lint with zero issues, 56 deterministic Vogon canaries, and 4 external-protocol canaries. I’m doing one last inventory across all three worktrees to confirm exact diff scope, whitespace cleanliness, and that no commits or pushes occurred.

Reviewed the Claude session, reproduced the three smoke-test failures, and fixed the remaining gaps across their existing branches.

• peyton/session-attach-worktrees / trail 1378

  • Subagent lifecycle events now follow the agent’s target worktree for Codex and Claude.
  • Settings metadata resolution no longer trusts hostile Git environment overrides.
  • Direct hook smoke test confirmed state is created in the target worktree.

• peyton/idle-sessions-survive-hooks / trail 1413

  • Live idle sessions survive later hook cleanup even when their original owner process has exited.
  • Updated regression coverage and checkpoint documentation.

• peyton/squash-redo-trailers / trail 1414

  • Redone deletions, pure renames, partially staged renames, nested deletions, and directory/file replacements retain trailers correctly.
  • Non-ASCII paths use NUL-delimited Git output.
  • Tree lookup now distinguishes actual absence from directories, gitlinks, and object-read failures.

Verification:

• mise run check passes independently on all three branches.
• Final redo branch: race-enabled tests, zero lint issues, 56 Vogon canaries, and 4 deterministic external-agent canaries passed.
• git diff --check passes everywhere.
• Independent review found no remaining reproducible correctness issues.

No commits or pushes were made. The existing untracked SESSION-ATTACH-WORKTREES.md was left untouched.

★ Insight ─────────────────────────────────────

• The redo bug was broader than missing deletion hashes: Git path state includes blobs, deletions, directories, renames, and non-directory ancestors.
• Walking tree components explicitly avoids interpreting go-git type errors as either false matches or false negatives.
• Keeping these fixes on their original branches preserves each trail’s scope and makes their PR gates independently reviewable. ─────────────────────────────────────────────────

If you authorize committing and pushing all three branches, I’ll do that and remain through the complete post-push gate cycle.

I’ll commit and push the three branch-scoped fixes separately, excluding SESSION-ATTACH-WORKTREES.md. I’m using the committer workflow to keep each commit narrowly scoped; after pushing, I’ll wait for every repository and PR gate, compare pre/post metrics, and address any actionable failures without merging.

★ Insight ─────────────────────────────────────

• Separate commits preserve the one-trail/one-branch review model and prevent a fix for one smoke test from obscuring another.
• The required pre-push lint is being rerun after the final formatting pass even though the broader checks already passed. ─────────────────────────────────────────────────

Pre-push baseline: all ordinary GitHub gates are green on PRs #2531, #2573, and #2574; each is blocked only by review plus the pre-existing failed Entire gate. No separate numeric risk/security classification is exposed in the PR check payload, so I’ll compare the named security gates—CodeQL and Entire Gates—before and after the push.

Pre-push lint is clean on all three branches. I’m committing only the reviewed files now, one branch at a time; the worktree notebook remains untracked and excluded.

The three commits are created:

• e92ae9ff0c — session/worktree following
• 53712a263d — idle-session preservation
• c4a41d12a8 — redo-trailer retention

Each branch is exactly one commit ahead of its existing upstream. I’m pushing them now, then I’ll monitor all three PR gate sets to terminal status.

The configured Entire transport accepted the objects but could not authenticate its downstream GitHub push (401), so no branch was updated. I’m using the repository’s direct authenticated github SSH remote for the same branch refs; this keeps the PR targets unchanged.

All three branches are now updated on GitHub. The post-push gate cycle has started; I’ll track ordinary CI, CodeQL/security, and Entire Gates separately for each PR until everything is terminal.

Gate progress is healthy so far: binary size and Actions CodeQL have passed on all three PRs; the supplemental CodeQL status is neutral consistently across all three, not a degradation. Tests, lint, licenses, and Entire Gates are still running.

No failures or degraded gates have appeared. PR #2531 is 9/15 complete; #2573 and #2574 are each 7/15 complete. The remaining work is the slower race/integration matrix, lint on the hosted runners, and Entire Gates.

Hosted CI is nearly complete and remains green. PR #2531 has only Entire Gates pending; #2573 and #2574 have only test-core plus Entire Gates pending. CodeQL, lint, licenses, platform tests, and the integration shards have not regressed.

Two Entire Gates have reached terminal failure on trails 1413 and 1414; all GitHub-native gates are green. I’m inspecting the failed check payloads and trail findings now before deciding whether another code change is required. PR #2531’s Entire gate is still running.

Trail 1413 is clean: 15/15 checks pass with no findings; its GitHub “Entire Gates” failure is only the required human approval state. Its monitors improved overall: risk 54→52 and security 13→8, confidence 87→86, drift 6→7.

Trail 1414 has one blocking high finding plus a new medium finding. Both concern provenance and appear actionable, so I’m using the Entire address-findings workflow to validate them, add regressions, and update that branch before rerunning its gates.

★ Insight ─────────────────────────────────────

• An Entire gate can report failure even when its internal checks pass if human approval is still required; that is an external/manual blocker, not a code failure.
• Trail 1414’s new issue is distinct from redo detection: stale SQUASH_MSG can misattribute unrelated staged content unless squash inheritance is content-gated too. ─────────────────────────────────────────────────

Entire Address Findings:

I’m validating the two trail 1414 findings against the current branch, highest severity first. I’ll resolve only findings whose regressions pass after the fix; the broader commit/push authorization remains in effect for completing the post-push gate cycle.

The installed CLI can read trail metadata but its findings endpoint is rejecting the saved session as unauthenticated. Repository instructions authorize refreshing Entire authentication, so I’m starting entire login; if the browser requires an account confirmation, I’ll surface that handoff immediately.

Authentication refreshed successfully, but this CLI build still reports “not logged in” only for the findings subcommand—a tooling defect. The authenticated trail UI provides the complete finding bodies, so I’m proceeding with local verification and fixes; I won’t mark anything resolved until the code and tests prove it.

The two issues are:

• High: condensation may treat an already-existing selected checkpoint as newly stamped.
• Medium: stale SQUASH_MSG can attach abandoned squash trailers to unrelated staged work.

I’m treating the squash finding as a provenance boundary, not merely a stale-file cleanup issue: trailer inheritance will require staged content to match a commit named by the checkpoint trailers in SQUASH_MSG. I’m first adding regressions for both git commit -m and Git’s seeded squash-message flow, because the latter already contains the stale trailer and must actively remove it.

The squash regressions are now green, including the existing legitimate squash cases. The gate uses Git’s own commit hashes embedded in SQUASH_MSG, then compares the current index state against those commits; no history-wide search or heuristic timestamp is needed.

For the high finding, I’m isolating condensation-target selection into a pure helper so a race where the selected checkpoint appears between selection and use can be reproduced deterministically before adding the recheck.

Both findings now have RED→GREEN regressions:

• Stale squash messages no longer copy—or retain seeded—trailers when staged content is unrelated.
• A condensation target that appears after selection is reclassified as preexisting before any session writes into it.

The complete strategy package passes. I’m running lint next, then the mandatory full mise run check before the follow-up commit.

The redo branch’s full gate is still running with lint clean. While monitoring trail 1378, Entire posted a new medium lifecycle finding: subagent/tool CWDs may be transient worktrees while their bookkeeping still targets a parent session. I’m treating it as a separate post-push review item and will validate the event identity semantics after the redo branch check finishes.

The full check hit one unrelated test-harness failure: TestAttach_DiscoversExternalAgents did not discover its temporary external agent, while the changed strategy package and all related tests passed. I’m rerunning that exact test to distinguish a transient harness issue from a real regression, then I’ll rerun the full gate as required.

The second full check is still the immediate gate for the squash/redo follow-up. Once it finishes cleanly, I’ll commit and push that fix, then tighten the session-follow behavior so subagent events can operate in their actual worktree without being mistaken for evidence that the parent session itself moved.

★ Insight ─────────────────────────────────────

• In this lifecycle design, “run this event in the payload’s worktree” and “the session has permanently moved worktrees” are separate facts.
• Subagent events need the former for accurate task baselines and touched-file tracking, but should not implicitly assert the latter. ─────────────────────────────────────────────────

The redo/squash follow-up now passes the complete repository check, including both deterministic E2E canaries. I’m doing the final scope check and required pre-push lint, then I’ll commit and publish it before returning to the worktree-follow finding.

The squash/redo PR now has follow-up commit 2339952584 pushed. That closes both review defects at the code level: condensation rechecks the chosen checkpoint’s existence, and stale SQUASH_MSG provenance is accepted only when its source commit actually matches the staged tree.

I’m now adding a regression boundary on the worktree-follow branch: subagent/tool events may follow their payload CWD for task-local bookkeeping, but only session-level turn events may mark that worktree as confirmed for session rehoming.

★ Insight ─────────────────────────────────────

• The fix deliberately keeps os.Chdir for SubagentStart and ToolUse; removing that would recreate the smoke-test gap by resolving child work against the launch checkout.
• The narrower change is the context capability: only TurnStart/TurnEnd receive WithAgentWorkingTree, which is the strategy’s authorization to rehome the parent session.
• The test covers both halves of the contract—CWD follows, session confirmation does not—so a future cleanup cannot “fix” one side by breaking the other. ─────────────────────────────────────────────────

The focused regression is green, and the full strategy package is green. The larger CLI package is still running; GitHub’s API was temporarily unreachable from the sandbox, so I’ll retry gate inspection after the local verification completes rather than treating that network hiccup as a gate result.

The first full check exposed only the repository’s intentional format-before-lint ordering requirement: the test table needed gofmt, and the check’s parallel formatter fixed it while lint correctly rejected the pre-format snapshot. I’m rerunning the full check on the now-formatted tree; no behavioral test failed.

The clean rerun has passed formatting and lint and is now in the race-enabled integration suite. While it runs, the important regression boundary is already covered locally: task-scoped hooks still execute in the child worktree, but they no longer carry the parent-session rehome authorization.
