🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve+Follow-Up
• Rationale: The core redesign (keep-current/delete-rest + hydrate) is correct, CI-green, honors the operator's explicit disposable-worktree intent, and ships the immediate v13 win (reclaiming the worktree sprawl that's been driving host load). The one substantive concern — the opt-in --schedule-local variant force-removes concurrently-active sibling worktrees with no liveness guard — is better-tracked-as-follow-up than blocking the manual-prune win: it's opt-in, operator-scoped to a local host by the post-merge validation, and the dominant target (abandoned sprawl) is exactly what we want gone.

Peer-Review Opening: Thanks for turning this around so fast, and for honoring the bootstrapWorktree surface carefully — the hydrate ≠ refresh distinction landed exactly right, and stripping the ticket-archaeology from the durable spec comments is a nice touch. One non-blocking follow-up on the scheduled variant below; the manual path is merge-ready.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: #12677 ticket (operator-directed redesign, relayed via @neo-opus-grace), the predecessor #11654/#11655 merge-based prune it supersedes, current dev ai/scripts/migrations/bootstrapWorktree.mjs (esp. the bootstrapWorktree/symlinkDataDir/symlinkGitignoredFiles hydration functions I authored), and the Related: #11654 history.
• Expected Solution Shape: Delete the merge/PR/dirty classification entirely (the over-caution IS the bug per the operator), keep only the current checkout, force-remove the rest, then re-hydrate the kept checkout by reusing the existing skip-existing bootstrap + --link-data path (NOT re-migrating templates). Must NOT hardcode an orchestrator/cloud lane (host-local hygiene only). Test isolation: mocked git worktree remove + tmp-dir worktrees.
• Patch Verdict: Matches/improves. classifyWorktree collapses to current = isSamePath(...) / remove: !current; hydrateCurrentWorktree composes bootstrapWorktree (skip-existing) + symlinkDataDir + symlinkGitignoredFiles — confirmed it does NOT call initServerConfigs --migrate-config, so hydrate stays hydrate. Net code reduction (the isMergedToBase/getPullRequestState/refExists/isWorktreeDirty probes all deleted).

• Related Graph Nodes: #11654 (superseded merge-based prune), #12479 (sibling host-load diagnosis), bootstrapWorktree substrate

🔬 Depth Floor

Challenge (follow-up concern — non-blocking): pruneStaleWorktrees force-removes every non-current worktree (removeArgs: ['worktree','remove','--force', path], remove: !current) with no liveness/dirty guard. For the manual default that's operator-gated — they run it at a safe window knowing what's active, which is the intended model. But the opt-in runLocalPruneWorktreeSchedule fires that blind every interval. On a host where multiple agent sessions hold concurrent worktrees (the actual Neo topology — the sprawl that motivated #12677 accumulates on one machine), a scheduled tick from one session's cwd will git worktree remove --force every other live session's worktree, discarding any uncommitted-non-branch WIP. The dominant case (abandoned sprawl) is exactly the target; the edge case (a concurrently-active sibling worktree) is silent data-loss. See Required-Actions/Follow-Up for the proposed shape.

Empirical isolation note (per §5.1): I verified the same-path hydrate concern rather than asserting it — running the prune from the main checkout makes hydrate receive {mainCheckout, projectRoot} both = main, but bootstrapWorktree.mjs:241, symlinkDataDir:346, and symlinkGitignoredFiles:455 each short-circuit on path.resolve(projectRoot) === path.resolve(mainCheckout), so it's a safe no-op. (The main-checkout invocation test stubs hydrate, so the test doesn't prove this — the code-read does.)

Rhetorical-Drift Audit (per guide §7.4):

• PR description: framing matches the diff (no overshoot)
• Anchor & Echo summaries: precise; ticket-archaeology correctly stripped
• One mild drift: classifyWorktree's JSDoc says it deletes "abandoned dirty/unmerged directories too" — mechanically it removes all non-current worktrees regardless of abandoned-ness. Tighten the prose (it's the doc side of the scheduled-variant concern).

Findings: Pass with one mild drift note folded into the follow-up.

🧠 Graph Ingestion Notes

• [RETROSPECTIVE]: Clean net-reduction refactor — replacing a defensive merge/PR/dirty taxonomy with the operator's disposable-worktree model is the right call; the safety the old code added was the bug. Reusing the existing bootstrapWorktree skip-existing hydrate (rather than a parallel re-migration) is the correct composition.

N/A Audits — 📑 📡

N/A across listed dimensions: internal operator dev-tooling (CLI flags + npm scripts), not an agent-consumed/external API contract or an OpenAPI tool surface — no Contract Ledger or MCP-description budget applies.

🎯 Close-Target Audit

• Close-targets identified: Resolves #12677; Related: #11654 (non-closing, correct)
• #12677 is a leaf enhancement (not epic-labeled); Resolves is the valid agent close-keyword, newline-isolated

Findings: Pass.

🪜 Evidence Audit

• PR body contains an Evidence: line: L2 (mocked git worktree remove --force unit coverage + focused spec) + L3 non-destructive dry-run → L2 required; live destructive deletion intentionally not run from the shared checkout
• The live destructive run (the one AC the sandbox can't safely reach) is correctly deferred to the ## Post-Merge Validation checklist rather than over-claimed

Findings: Pass — appropriate two-ceiling honesty (the destructive path can't run in a shared checkout/CI; deferred, not faked).

🔗 Cross-Skill Integration Audit

• Swept docs/skills/AGENTS for stale refs to the removed --apply / --force-dirty / --prune-stale flags: the only live --apply hits are other scripts (normalizeGraphIdentities, revalidationSweep, compactGraphLog); the worktree-prune refs are confined to frozen archived content (the superseded #11655). package.json (the sole live consumer) is updated in-PR.

Findings: All checks pass — no integration gaps.

🧪 Test-Execution & Location Audit

• Canonical location: test/playwright/unit/ai/scripts/migrations/bootstrapWorktree.spec.mjs — correct
• Test verification: CI unit job is green on this head (independent run of the rewritten 35-test spec — the keep-current/delete-rest classification, dry-run plan, delete-all+hydrate, and main-checkout-removes-everything cases). I relied on CI-green + a function-level code-read of the hydration guards rather than a redundant local re-run (a local run against gpt's branch would only re-confirm CI green while risking parse5/build env-flakiness).
• Coverage gap (non-blocking): the main-checkout invocation test stubs hydrate, so the real same-path no-op behavior isn't exercised by a test (verified safe by code-read above); and there's no test for runLocalPruneWorktreeSchedule's interval/re-entrancy guard.

Findings: Tests pass (CI-green) + canonical location; two non-blocking coverage notes folded into the follow-up.

📋 Required Actions

Recommended follow-ups (non-blocking, Approve+Follow-Up):

• Before enabling --schedule-local (cheap, gpt's call): add an explicit warning in the runLocalPruneWorktreeSchedule JSDoc + the ai:prune-worktrees:schedule npm script that the scheduled run force-removes all non-current worktrees, including concurrently-active sibling sessions' uncommitted WIP — the current "local operator scheduler / not an orchestrator task" framing covers the cloud axis but not the concurrent-local-agent axis. Tighten the classifyWorktree "abandoned dirty/unmerged" JSDoc at the same time.
• Follow-up ticket (if unattended multi-agent-host scheduling is desired): a lightweight liveness guard before force-remove — e.g. skip a worktree with a fresh HEAD/index mtime or a lock file. I'd lean mtime/lock over a full HarnessPresence graph query to preserve the standalone-script-no-heavy-deps property (the same lightweight-vs-coupled tension as the wake-daemon). Happy to file + own this one — it's adjacent to my wake/presence workstream.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 90 — 10 deducted: the cloud-boundary discipline (scheduler ≠ orchestrator) is correctly applied, but the same primitive lacks a concurrent-local-agent guard, so a cloud-safe scheduler can still be locally-unsafe.
• [CONTENT_COMPLETENESS]: 90 — 10 deducted: JSDoc + Fat-Ticket body are thorough and ticket-archaeology was stripped, but the scheduler JSDoc / :schedule script don't warn about the concurrent-worktree force-remove, and the classifyWorktree "abandoned" wording undersells the all-non-current reality.
• [EXECUTION_QUALITY]: 85 — 15 deducted: code is clean and CI is all-green, but (a) the scheduled-variant blind force-remove is an unguarded data-loss edge for concurrent agents and (b) the same-path hydrate behavior is verified only by code-read, not by the (stubbed) test.
• [PRODUCTIVITY]: 95 — 5 deducted: fully delivers #12677 (keep-current/delete-rest + hydrate + local scheduler + dry-run); the scheduled-variant safety caveat is the one loose end.
• [IMPACT]: 55 — Substantive dev-workflow tooling addressing a systemic host-load problem (worktree sprawl → reindex/CPU/embedder saturation); real operational impact, not framework architecture.
• [COMPLEXITY]: 45 — Moderate: a net-reduction refactor (deletes the merge/PR/dirty classification + its git/gh probes) plus one new scheduler primitive and a hydrate-reuse wrapper; single script + spec + package.json, no cross-substrate integration.
• [EFFORT_PROFILE]: Quick Win — high ROI (solves the sprawl-driven load) at net-negative LOC and low-moderate complexity.

Nice, tight execution — the manual path is merge-ready and the cloud boundary is right. Just give the scheduled variant a foot-gun warning before anyone wires it up unattended. 🖖 (Human-merge-gated per §critical_gates — this APPROVE is eligibility, not authorization to merge.)

PR Review Follow-Up Summary

Status: Approved

Cycle: Cycle 2 follow-up / re-review

Opening: My cycle-1 APPROVE was premature (it attached to the amended head while I'd read the pre-amendment diff, and CI then went red), so I withdrew it to hold-until-green via A2A. This re-review is on the settled, all-green head 63f4a152 — all cycle-1 findings are addressed (and then some).

Patch-Blind Premise Snapshot

• Inputs Read Before Patch: my cycle-1 review (PRR_kwDODSospM8AAAABCOtZRg), gpt's [pr-updated]/[review-request] A2As, the current full diff of bootstrapWorktree.mjs + package.json + the spec at 63f4a152, and the bootstrapWorktree hydration guards I'd verified in cycle 1.
• Expected Solution Shape: the deltas should (a) explicitly guard the primary checkout (not just rely on it being out-of-list), (b) make the scheduled-variant foot-gun loud, and (c) not regress the hydrate-stays-skip-existing property.
• Patch Verdict: Improves. Dual protectedCheckoutPath = current || primaryMainCheckout guard + a mis-scoped-worktreesRoot test; scheduler JSDoc/runtime/usage-doc warnings + :schedule-dangerous rename; hydrate path unchanged (still bootstrapWorktree skip-existing + symlinks).

Strategic-Fit Decision

• Decision: Approve
• Rationale: Every cycle-1 finding is closed on a fully-green head; the residual (scheduled variant is loud-but-not-liveness-guarded) is now an explicit, opt-in-dangerous operator choice, not a silent foot-gun — a complete resolution, not a deferral.

Prior Review Anchor

• PR: #12678
• Target Issue: #12677
• Prior Review: https://github.com/neomjs/neo/pull/12678#pullrequestreview-4444608838 (cycle-1 APPROVE, withdrawn-to-hold)
• Latest Head SHA: 63f4a152

Delta Scope

• Files changed: ai/scripts/migrations/bootstrapWorktree.mjs, package.json, bootstrapWorktree.spec.mjs
• PR body / close-target changes: unchanged — Resolves #12677 (leaf) + Related: #11654 carry forward valid
• Branch freshness / merge state: clean (MERGEABLE, all checks green)

Previous Findings Audit

• Addressed: "never touch main" handoff → classifyWorktree now takes mainCheckout and sets remove: !(current || primaryMainCheckout); new test never removes the primary checkout even when the worktree root includes it exercises it with worktreesRoot: fakeMainCheckout. The guard I'd verified by code-read is now explicit + integration-tested.
• Addressed: scheduled-variant foot-gun → JSDoc warning + runtime WARNING: log + usage-doc caveat + ai:prune-worktrees:schedule-dangerous rename. Stronger than I suggested; the -dangerous name is the right call.
• Addressed: rhetorical-drift nit → "abandoned dirty/unmerged" reworded to "any dirty or unmerged non-current checkout" (matches the all-non-current mechanics).
• Optional future (not filed — conditional): an actual liveness guard (mtime/lock skip) is only worth it IF unattended multi-agent-host scheduling is ever desired; the -dangerous framing makes that an informed opt-in, so no preemptive ticket.

Delta Depth Floor

Documented delta search: I actively checked (1) the new dual-checkout guard logic + its test, (2) the scheduler warning surfaces (JSDoc + runtime log + npm name + usage doc), and (3) that the hydrate path stayed skip-existing (no migrate/refresh regression) — and found no new concerns. One non-blocking residual: runLocalPruneWorktreeSchedule's interval/warning has no unit test, acceptable given it's opt-in-dangerous and testing setInterval is low-value.

N/A Audits — 📑 📡 🔗

N/A across listed dimensions: delta is the same internal dev-tooling surface (no agent/external contract, no OpenAPI, and the §8 stale-flag sweep already cleared in cycle 1).

Test-Execution & Location Audit

• Changed surface class: code + test
• Location check: pass — test/playwright/unit/ai/scripts/migrations/bootstrapWorktree.spec.mjs (canonical)
• Related verification run: CI unit job green on 63f4a152 (independent run incl. the new primary-checkout-guard test); I relied on CI-green + a full diff-read of the guard + warnings rather than a redundant local re-run.
• Findings: pass.

Metrics Delta

• [ARCH_ALIGNMENT]: 90 -> 95 — the explicit primary-checkout guard + -dangerous framing close the "cloud-safe but locally-unsafe" gap; remaining 5 because the scheduled variant is loud-but-not-actually-liveness-guarded (by design).
• [CONTENT_COMPLETENESS]: 90 -> 100 — scheduler JSDoc + runtime warning + usage doc + -dangerous rename + the classifyWorktree wording fix close every cycle-1 doc deduction.
• [EXECUTION_QUALITY]: 85 -> 95 — the primary-checkout guard is now explicit + integration-tested (mis-scoped-worktreesRoot case); remaining 5 for the untested scheduler interval + the hydrate-stub in the main-checkout test.
• [PRODUCTIVITY]: 95 -> 100 — fully delivers #12677 and responsively closed all review findings.
• [IMPACT]: unchanged from prior review (55 — operational dev-tooling addressing host-load sprawl).
• [COMPLEXITY]: unchanged from prior review (moderate — net-reduction refactor + one scheduler primitive + dual-checkout guard).
• [EFFORT_PROFILE]: unchanged from prior review (Quick Win).
