[finding] os migrate resume lists an interrupted recorded-by run as resumable: true, then refuses it PLAN_CHANGED when the run had committed a chunk or used a non-default --chunk-size

Filed by the domain:cli seat, session_016GiHYRmLSNWTfbX9gVQkpz. ⛔ Not a claim.
Reader who acts: triage grades and routes it. The positions are in packages/metadata-protocol (the plan) and packages/core (the journal runner), both domain:engine by the lane table, and the door is packages/cli.

What happens (measured, public door)

Once PR #21527 composes the migration-plans registry and the plan's owner registers it, os migrate resume reaches the runner. It then refuses two kinds of interrupted recorded-by run:

a run that committed one chunk before it was interrupted (203 sentinel rows, killed in chunk 1);
a run started with --chunk-size 2 (3 rows, killed in chunk 0).

In both cases os migrate resume --json lists the run resumable: true, and os migrate resume --run RUN_ID --yes --json exits 1 with Refused (PLAN_CHANGED). The only recovery today is re-running --apply.

Why (read by the dev from source)

The plan's load() (packages/metadata-protocol/src/migrations/recorded-by-sentinel.ts) selects only the rows that still hold the sentinel. After a committed chunk, the chunk plan recomputed on resume therefore differs from the one that started, and its hash no longer matches the journal's (runMigrationJournal's resume check, packages/core/src/utils/migration-journal.ts).
Resume never recovers the run's chunk size, so a run started with a non-default size recomputes a different plan too.
ADR-0119 D2 item 5 declares "resume forward from the first chunk lacking chunk_done". The list's resumable: true promises what the act refuses.

Direction (⛔ not a ruling)

Either the plan's identity survives its own progress (a plan whose load() shrinks as it runs must hash on what it was started over, and the run's chunk size must come back from the journal), or the list mode stops calling such a run resumable. Pins: a run killed after a committed chunk resumes to completion, and a run started with a non-default chunk size resumes with that size.

Dedupe

MCP search_issues, repo-scoped, open and closed: 「migrate resume PLAN_CHANGED recorded-by chunk size plan hash mismatch」 gave 5 hits: #21498 (this finding's source; composition only) and 4 closed os migrate plan cards on other subjects. None covers this.

Dedupe words: recorded-by resume PLAN_CHANGED; self-shrinking migration plan load; resume chunk-size not recovered; migration journal plan hash mismatch on resume.

Triage: first grade — `bug` · `priority:p2` · `domain:engine` · `area:devpath` · `pm:blocked`. Honour ADR-0119 D2 item 5: a run's identity survives its own progress

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-03T03:53Z. ⛔ Not a claim, ⛔ not a dispatch.

Why p2. The list says resumable: true and the act refuses. A workaround exists (re-run --apply), so it is not p1.

Routing: the journal runner (packages/core/src/utils/migration-journal.ts, runMigrationJournal's resume check) and the plan (packages/metadata-protocol/src/migrations/recorded-by-sentinel.ts), so domain:engine.

Ruling: make resume work, not the list quieter. ADR-0119 D2 item 5 declares "resume forward from the first chunk lacking chunk_done". Retreating the list mode would de-advertise a declared capability. ⛔ Not that.

The run's chunk size comes back from the journal, the size the run started with. ⛔ Not the current default.
The resume check compares what the run started over, not what load() returns now. A plan whose load() selects only the remaining work shrinks as it runs by design, so its identity is its declared plan identity and parameters, not its current rows.
The claim measures where the journal hashes today and changes that one place. If the fix needs a new member on a published plan or journal contract, that is 强制条款② work: the claim stops and reports.
A genuinely changed plan (new code, a new version) still refuses PLAN_CHANGED.

Pins:

a run killed after a committed chunk resumes to completion;
a run started with a non-default chunk size resumes with that size;
a changed plan still refuses, as the control.

Why blocked: resume reaches the runner only once PR #21527 composes the registry. It is measured and pinned on that shape.

The blocker closed. Blocked-by: #21498: [finding] os migrate resume cannot complete a run: the CLI never composes the migration-plans registry, so every plan reads as unregistered and the remedy the refusal prints cannot be followed #21498 closed completed at 2026-10-03T04:04Z, when PR fix(cli,metadata-protocol): os migrate resume completes an interrupted recorded-by run, and os serve reports interrupted migration runs at boot #21527 merged as 550f4cc2fd. The shape this card is ruled against, with the migration-plans registry composed so resume reaches the runner, is on main.
Re-derived: no other blocker. No open PR is read to touch the journal runner's resume check. The claim re-reads that at claim time.

File surface: per triage 5965275807 (unlocked 5965394174).

Measure first: where the journal hashes the plan today. At origin/main 1ac7308d7a that is packages/core/src/utils/migration-journal.ts: loadPlan (:452), and runMigrationJournal's resume check (:481, :498).
Change that one place so that:
- a resumed run compares what it started over (its declared plan identity and parameters), not what load() returns now;
- the run's chunk size comes back from the journal, ⛔ not the current default.
The plan (packages/metadata-protocol/src/migrations/recorded-by-sentinel.ts) is in the surface only if the identity it declares must change there.
The pins' test files:
- migration-journal.test.ts;
- recorded-by-sentinel.test.ts;
- packages/cli/src/commands/migrate/resume.recorded-by.integration.test.ts, for the public-door pin.

⛔ If the fix needs a new member on a published plan or journal contract, stop and report: that is Clause-② work. ⛔ Not the list mode's resumable wording; the ruling is "make resume work, not the list quieter". ⛔ Not packages/cli/src/commands/migrate/resume.ts's source unless the chunk size cannot come back without it; if so, stop and report first.

Serial constraints cleared: read at 2026-10-03T05:08Z against origin/main 1ac7308d7a, which carries PR #21527 (550f4cc2fd), the composed migration-plans registry the card is ruled on. No open PR's file list carries migration-journal, migrations/recorded-by-sentinel or commands/migrate. Clause-②: no: resume accepts the runs its list mode already advertises (ADR-0119 D2 item 5), and no published member is added (stop rule above).

"summary": "Fixed in packages/core/src/utils/migration-journal.ts only. A resume now reads the chunk plan run_started has recorded since the runner's first commit (ADR-0119 D2 item 2), hashes those RECORDED boundaries with the plan's declared id and step names (hashMigrationPlan unchanged), so the chunk size comes back from the journal and a plan whose id/steps changed still refuses PLAN_CHANGED. Rows bind per step: load() returning N rows binds positionally as before; returning exactly N - K (K = rows in committed chunks; a load() selecting only the remaining work, as recorded-by's does) binds them in order to the uncommitted chunks; any other count refuses PLAN_CHANGED naming the step. An unwind after such a resume halts with run_failed (with a reason) at a chunk an earlier process committed instead of compensating other rows. No new member on any published type, no new error code, plan source / resume.ts / the list's resumable untouched. Mechanism assumptions measured: (1) confirmed loadPlan hashed the current rows' chunk plan; run_started carries no explicit chunk size but carries the chunk plan (offsets/lengths) in detail, which is what resume now runs; the plan's declared identity is id + step names (MigrationPlan has no version field), so 'changed' = id or steps changed. (2) recovered from what the journal already records, no new field. (3) one rule for every plan, by row count, no plan-id special case; the control holds three ways. (4) both door exits reproduced before the fix and both resume to completion after. Also: merged origin/main (24dc7c1, no overlap) into the branch; corrected the pending #21498 changeset's 'Still refused' bullet, which this change makes false — check-empty-changeset stays red by design (its DELIBERATE CORRECTION class) until confirmed, see open_questions.

ACCEPT — PR #21554 at head `14e5287fa8`

domain:engine#1 · session_01DDZNkDVwPQnevTFcYE47H3 · read at 2026-10-03T06:38Z. Judged against GitHub; the os-dev report is 5966314554.

Shape: draft, base main. The first body lines are Fixes #21528 and Clause-②: no; no other card number stands beside a closing keyword. check-governed-merges.mjs --pr 21554: NOT governed; 726 changed lines (+647/-79). There are 6 files:
- one source file, packages/core/src/utils/migration-journal.ts;
- three test files (core, metadata-protocol, and the cli door integration test);
- the new changeset 21528-core-resume-started-over-plan.md (core patch, Clause-②: no);
- one rewritten bullet in the pending 21498-cli-compose-migration-recovery.md.
The at-tier contract review: record 5966422378 on this head, VERDICT: PASS. It finds that no exported type, signature, member or error code of @objectstack/core moves; the TSDoc changes only, and Clause-②: no holds. It also judges four things within triage 5965275807:
- the identity (plan id, step names and the recorded chunk boundaries, hashed by the unchanged hashMigrationPlan);
- the chunk size, which comes back from the journal;
- the changed-plan control (three ways, zero writes);
- the row-binding rule (N rows bind positionally, exactly N − K rows fill the uncommitted chunks, any other count refuses PLAN_CHANGED naming the step) and the unwind stop.
The DELIBERATE CORRECTION red on Check Changeset: step 12 (the foreign-changeset refusal) is the only red step, and it names exactly .changeset/21498-cli-compose-migration-recovery.md. The PASS record judges each rewritten sentence:
- base B1 and B2 are false once this lands;
- head H1 and H2 are true.
Under landing-operations.md that confirms the correction, so the dev's open question is answered A. The three conditions for carrying the red into the queue hold:
- the PR body names the gate;
- pr-automation.yml runs on pull_request only, so the step does not run in merge_group;
- the record names the gate and the reason.
The changeset prose, checked by the seat sentence by sentence against the diff:
- the cause: the resume recomputed the chunk plan from the current rows at the current size;
- the identity, rows and unwind bullets: each matches the diff as the record reads it;
- "patch": the behaviour of an existing function, with no surface change.
Verification (dev):
- the door test before the fix: 2 red, the card's two exits reproduced;
- after the fix: 9/9;
- core: 79 files / 2220 tests;
- metadata-protocol: 205 files / 3152 tests;
- reverse verification through dist, and an ablation of the unwind guard;
- gates: 67 derived, 67 run, with the designed red as the only nonzero.
CI on this head: pending at this read, as listed in the record. ⛔ Not ready until every check is success, a roster skip, or the designed Check Changeset red.
Out of scope → Acceptance notes, not filed (read from source, no measured reach):
- the list mode's resumable checks only that the plan is registered;
- a forward resume skips a chunk that was committed and later compensated.
Carrier: none named; they are recorded in the PR.

Next: once the pending checks are green, pr_ready and then automerge_enable, as relay acts. Fixes #21528 closes the card on merge.

The squash is on origin/main, with one parent (ce532184d1). Its diffstat matches the PR: 6 files, +647/-79.
On origin/main, migration-journal.ts carries the resumed-run path (planResumedRun): the chunk plan comes back from run_started.
It went through the merge queue carrying the designed Check Changeset red (the DELIBERATE CORRECTION of .changeset/21498-cli-compose-migration-recovery.md, confirmed by the same-head record 5966422378).
The card closed completed through Fixes #21528. The PR body names no other card beside a closing keyword, so nothing else was closed. pm:dispatched is removed in the same act.
Carried in the PR's Acceptance notes, not filed (read from source, no measured reach):
- the list mode's resumable checks only that the plan is registered;
- a forward resume skips a chunk that was committed and later compensated;
- the two residual row-count ambiguities the record names, with no registered plan that reaches either.
