Closes #1827

What was wrong

The bulk-archive workflow's step 8c ran mv with no check that the archive target already exists:

mkdir -p "<planningHome.changesDir>/archive"
mv "<changeRoot>" "<planningHome.changesDir>/archive/<target-name>"

POSIX mv moves changeRoot inside an existing target directory and exits 0, so a same-day name collision produced

openspec/changes/archive/2026-09-10-add-auth/2026-09-10-add-auth/

and the agent recorded the change as archived successfully. The nested change leaves a second .openspec.yaml at a depth nothing scans.

The workflow already promised the opposite in three places:

  • Guardrails — "If archive target exists, fail that change but continue with others"
  • Failure output template — some-change: Archive directory already exists
  • Partial-success output template — the same string

The single-change workflow (archive-change.ts) implements the check. Only the bulk path was missing it.

The change

Adds the existence check between the target-name rule and the mv, worded to match the single-change workflow and to produce the outcome step 8d already declares:

**Check if target already exists:**
- If yes: record this change as Failed with `Archive directory already exists`, leave `changeRoot` where it is, and continue with the remaining changes
- If no: move `changeRoot` to the archive directory

Failing only that change and continuing preserves the batch semantics the guardrail describes.

Applied to both delivery surfaces in bulk-archive-change.ts (skill + command template), with skills/openspec-bulk-archive-change/SKILL.md regenerated via node scripts/generate-skillssh.mjs and parity hashes via node scripts/regen-parity-hashes.mjs (3 hashes, all bulk-archive).

Tests

New test/core/templates/bulk-archive-existing-target.test.ts asserts against both bodies: the check is present, it sits between the target name and the mv, and the guardrail and failure output stay in agreement.

Verified the test is not vacuous — reverting the template change fails the two behavioral assertions and passes only the guardrail-consistency one.

Verification

pnpm build              ✅
pnpm test               ✅ 4564 passed, 2 failed
pnpm exec tsc --noEmit  ✅
pnpm lint               ✅

The 2 failures are test/core/completion-tip.test.ts ("prints the tip on the first run", "defers the tip on silent runs"), both expected false to be true. They fail identically on a clean checkout of main at 9d4e597 with my changes stashed, so they are unrelated to this PR — please let me know if they are green on your CI and I will dig into the environment difference.

AI disclosure

Written with Claude Code (claude-opus-5). I ran the four CI commands locally and confirmed the new test fails without the source change.

Maintainer hardening (2a20d15, 5f4eac6, da066e2, b5e0e7d)

Status: LGTM after hardening. Safe to merge: this changes templates only, with no code or dependency changes.

The first version checked the target at step 8c, which runs after step 8a has already synced the change's delta specs. A collision still left main specs rewritten while the change stayed active. openspec archive avoids this by checking the target before it touches any spec (src/core/archive.ts, "Settle the archive destination BEFORE touching any spec"). The batch now works the same way:

Where What
Step 3d (new) Work out each target name and check it before any write. If a target already exists, or two selected changes map to the same target (for example add-auth and 2026-09-16-add-auth), mark those changes Blocked.
Step 3d / 7 A blocked change is never synced or moved. It stays out of conflict resolution and the archive-everything option, and is reported as Failed.
Step 3d → 8c Works out the dated target name once in 3d and reuses it at the move. Without this, a batch that runs past midnight checks yesterday's name, syncs specs, then collides at today's name (from alfred and CodeRabbit review).
Step 8c Checks again right before mv, in case the target was created mid-batch. If it fails there, the agent reports any main specs step 8a already synced.
Step 8c (after mv) If the change landed nested inside a target that appeared late, moves it back and records Failed. Never reports it as archived.
Step 7 ready-only Blocked changes stay Failed instead of being recorded as Skipped.
Guardrails Adds a rule to check every target before the first main-spec write.

Proof: the new tests checks every archive target before the first main-spec write and reuses the target name recorded in step 3 for the move each fail with the template change reverted and pass with it. Also: skill mirror and parity hashes regenerated, tsc and lint clean, merged with current main; full suite 5023 passed / 2 failed. Those two (artifact-workflow Cursor skills, config-profile in-process apply) already fail on main and do not involve bulk archive.

Summary by CodeRabbit

  • Bug Fixes

    • Bulk archiving now checks all destinations before writing or moving changes.
    • Existing or duplicate destinations are reported as failed, leaving affected changes in place.
    • Remaining eligible changes continue processing, with destinations rechecked before each move.
    • Prevents changes from being incorrectly archived or reported as successful after a late conflict.
  • Tests

    • Added coverage for destination conflicts and consistent behavior across bulk-archive workflows.

Step 8c ran `mv` with no existence check. POSIX `mv` moves changeRoot
inside an existing target directory and exits 0, so a same-day name
collision produced archive/<target>/<target>/ and was recorded as a
successful archive.

The workflow already promised the opposite in three places: the guardrail
"If archive target exists, fail that change but continue with others" and
both failure output templates listing "Archive directory already exists".
The single-change archive workflow implements the check; the bulk path did
not.

Closes Fission-AI#1827

📝 Walkthrough

Walkthrough

Bulk archive workflows now pre-check all archive targets before writing main specs. Existing or duplicate targets block affected changes without syncing or moving them. The workflows re-check targets before each move and continue with remaining changes.

Changes

Bulk archive collision handling

Layer / File(s) Summary
Archive target validation
skills/openspec-bulk-archive-change/SKILL.md, src/core/templates/workflows/bulk-archive-change.ts
Both bulk archive delivery surfaces pre-check existing and shared targets. Blocked changes are excluded from syncing and conflict resolution. The move step re-checks targets and records late collisions as failed.
Template behavior tests
test/core/templates/bulk-archive-existing-target.test.ts
Tests cover preflight ordering, blocked and unsynced changes, collision handling, target reuse, nested-move rollback, failure output, guardrails, and continuation behavior for both delivery surfaces.
Release and parity updates
.changeset/bulk-archive-existing-target.md, test/core/templates/skill-templates-parity.test.ts
The changeset declares a patch release. Parity hashes reflect the updated templates and generated skill content.

Reviewed and verified independently — this looks right to me.

The bulk path was the only one missing the guard; archive-change.ts:140 has the identical check and the added wording matches it. Both delivery surfaces are covered, and re-running generate-skillssh.mjs + regen-parity-hashes.mjs was a no-op, so the generated skill and parity hashes are honest.

I confirmed the tests aren't vacuous: reverting the template guard fails 2 of the 3, exactly as you described.

On your open question about the 2 local failures — CI is green across linux/macos/windows, so there's nothing to dig into. For what it's worth I saw a different pair fail locally (artifact-workflow, config-profile), and both fail identically on a clean main at 9d4e597. Local environment noise either way.

Note: your fork's CI had never run — both workflows sat at action_required. I approved them, which is why checks just appeared.

For maintainers: #1796 fixes the same bug structurally, by delegating the move to openspec archive instead of shell mv. I've labeled it design-review since it amends the opsx-archive-skill spec. This PR stands on its own regardless of where that lands.

The existence check at the move ran after step 8a had already synced the
change's delta specs, so a collision still left main specs rewritten for a
change that stayed active. `openspec archive` settles the destination before
touching any spec; the batch now does the same in step 3 (including two
selected changes that resolve to the same target), keeps blocked changes out
of sync, conflict resolution, and the archive-everything option, and
re-checks just before the move.

One data-integrity blocker remains. Step 3d computes and checks each dated archive target, but step 8c recomputes the target name. If a batch crosses midnight, preflight can validate yesterday’s target, then sync main specs before step 8 discovers a collision at today’s target, leaving main specs changed while the change remains active. Persist each change’s computed target during step 3d and reuse that exact value for the late collision check and mv on both generated surfaces and the committed skill; add coverage pinning the reuse. The branch is also currently merge-conflicting and will need resolution before approval.

Merges main (parity-hash conflict resolved by regeneration).

Step 8c recomputed the dated target name, so a batch that crossed midnight
checked yesterday's target in step 3, synced main specs, then collided at
today's target with the change still active. Step 3d now computes and
records each change's <target-name> once; step 8c reuses it unchanged for
the late check and the move.

@alfred-openspec Addressed in da066e2. The target name is now worked out once in step 3d, and step 8c reuses it unchanged. Before this, a batch running past midnight could check one date and then move to another. Both generated surfaces and the committed skill are updated, and a new test (reuses the target name recorded in step 3 for the move) pins the reuse. I also merged main, which resolves the parity-hash conflict.

The last target check and `mv` are separate steps, so a target created in
between still nested the change with exit 0. Step 8c now confirms the move
did not land inside the target and moves the change back, recording
`Archive directory already exists`, instead of reporting success.

The ready-only option recorded every non-Ready change as Skipped, which
misreported archive collisions; Blocked changes now stay Failed.

The guardrail still read 'uses current date', which invites recomputing the

Re-reviewed current head f2831cc. The earlier data-integrity blocker is resolved: step 3 records each dated target once, step 8 reuses it unchanged, blocked changes remain Failed in every confirmation path, and a late nested move is restored instead of reported as success. The committed skill and both generated surfaces stay in parity. Focused validation: 36 tests passed, plus typecheck and lint; CodeRabbit threads are resolved. Approving.

Keep this branch's step 3 guardrail alongside Fission-AI#1775's profile-aware sync
handoff, and regenerate the parity hashes.

Re-reviewed current head 1e5394a after its merge from main. The merge preserves the persisted archive target, blocked-state handling, and late-move recovery, while integrating the profile-aware sync handoff. No unresolved review threads remain and all required checks pass. Approving.
