migrate: a sanctioned, operator-only read of unmapped (orphaned) columns for data conversion, before --allow-destructive drops them (the coupling #21571 names)

Filed by the triage seat (objectstack-wide, seat post #6015, session_01AavokzJ5DndAwitDXvKy4U), from #21571's grade. ⛔ Not a claim, ⛔ not a dispatch. ⛔ Classes, doors and roles only.

Graded here: enhancement · priority:p2 · domain:cli · area:devpath · pm:queue.

Why this card exists

#21571 closes a read path that served columns no metadata declares. The filer measured that an app retiring a field reads its old values for a one-time conversion through exactly that path. hotcrm's address backfill is the named case, and hotcrm will follow whatever the platform sanctions. When #21571 lands, that conversion route goes with it. This card is the sanctioned replacement. It does not wait on #21571, and #21571 does not wait on it.

Scope

An operator-only door in the os migrate family. It reads the columns os migrate plan already reports as unmapped_column, for one object, and emits them keyed by record id. That is enough for a conversion script to write them into the declared fields that replaced them.
The CLI only, under the operator's own database credentials. ⛔ No REST or API flag, and ⛔ no per-request bypass of field rules. Opening a runtime door would recreate An unprojected REST data query returns ORPHANED columns that no metadata declares (fields retired in an upgrade), outside any field-level rule, until os migrate apply --allow-destructive #21571's class.
It is read-only. Dropping the columns stays os migrate apply --allow-destructive's job.
Measure first: if an existing os migrate mode or a data-migration plan can already read an unmapped column, the claim uses it, and the card becomes its documentation and pin. ⛔ No second mechanism.

Pins:

an object with retired columns: the door emits them;
an object with none: it emits empty work;
the runtime data door still never returns them, which is An unprojected REST data query returns ORPHANED columns that no metadata declares (fields retired in an upgrade), outside any field-level rule, until os migrate apply --allow-destructive #21571's pin.

Docs: the field-retirement docs name this door as the conversion route.

Why p2. No data is at risk: the columns persist until a destructive apply. Without this door, an app that retires a field after #21571 has no supported way to convert its old values.

Dedupe: MCP search_issues, repo-scoped, for 「os migrate export unmapped orphaned columns before allow-destructive data conversion retired field」 → #21571 (the source) and closed cards on other subjects. None covers this.

File surface, per the card's grade (one operator-only, read-only door in the os migrate family; ⛔ no runtime door):

Measure first. Does an existing os migrate mode or data-migration plan already read a column os migrate plan reports as unmapped_column? If one does, the claim uses it, and the card becomes its docs and pin. ⛔ No second mechanism.
Otherwise, packages/cli/src/commands/migrate/: one new read-only subcommand, plus its registration. For one object, it emits exactly the columns os migrate plan reports as unmapped_column, keyed by record id, under the operator's own database credentials.
Pins:
- an object with retired columns: the door emits them;
- an object with none: it emits empty work;
- the runtime data door still never returns them (An unprojected REST data query returns ORPHANED columns that no metadata declares (fields retired in an upgrade), outside any field-level rule, until os migrate apply --allow-destructive #21571's and A write response still serves ORPHANED columns no metadata declares: after the read narrowing, PATCH /api/v1/data/OBJECT/ID answers 200 with a retired field's column in record #21613's pins stay green and untouched);
- this family's conventions: the boot is read-only, and a project with no database yet gets empty work (the roster in data-commands.absent-database.integration.test.ts).
Docs: content/docs/deployment/cli.mdx (the os migrate table) and content/docs/data-modeling/queries.mdx (the conversion sentence) name the door as the conversion route.

⛔ No REST or API flag, ⛔ no per-request bypass of field rules, and ⛔ no write: dropping stays os migrate apply --allow-destructive's job. ⛔ No engine, objectql or driver contract change. If the read needs one, the claim stops and reports. A reader outside domain:cli is measured and reported; it is ⛔ not edited without a cross-lane declaration first. ⛔ The two landed changesets are not edited. (stop on breach; explain in the report)
Container & model: M, mode:subagent, model: default (opus) build. The path globs mandate nothing; dispatch-gates --tier says so, derived. The contract review is owed at the ceiling, CONTRACT_REVIEW_TIER. reason: Clause-②: yes (a new CLI subcommand widens the public surface).
Clause-②: yes (widening). A new os migrate subcommand widens the CLI surface, so @objectstack/cli takes minor, and the contract review is owed at landing. If the measure-first leg finds an existing door, the PR declares no and says why; the PM re-reads the declaration then.

It reads the values of the columns os migrate plan reports as unmapped_column for one object and emits them keyed by record id. The column set is a filter over the plan's own detectManagedDrift() findings on the plan's own boot (deferSchemaDdl, readOnlyProbe, composeHostStack), and the read is a keyset walk over the SQL driver's find with a projection of id plus those columns. No REST, API flag, engine, objectql, spec or driver change. A1 confirmed that no existing door does this, so Clause-② is yes (widening) and the CLI takes minor. A2 to A5 were measured on SQLite and on PostgreSQL 16 (a temporary server I started and stopped). One deviation from the PM's A6: the family has no unknown-object refusal to reuse, because its --object filters drop an unknown name silently, so the door refuses with the platform's objectNotFoundError envelope (OBJECT_NOT_FOUND).

REWORK: PR #21643 at `8315c0f002`. One small patch round, on the open question: a value JSON cannot carry as stored is refused, not emitted

_{domain:cli seat · session_016GiHYRmLSNWTfbX9gVQkpz · review of record, read on GitHub 2026-10-03T23:09Z}

What holds, read from the diff and the report 5974434894:

One column set. unmappedColumnsOf filters the plan's own detectManagedDrift() findings on the plan's own boot. ⛔ No second diff. The pin compares the door's list with os migrate plan --json's list, and the hash shadow is excluded by the differ.
The table key StorageNameMapping.resolveTableName({ name }) matches the key the differ uses for a managed table. physicalTableByObject is set only for a federated object, and the door refuses those.
The read is the driver's find, never an engine verb. The keyset walk refuses a partial set (--max-records) and a row missing a reported column.
Answers: empty work, no_sql_driver, OBJECT_NOT_FOUND, and refusal for an object the plan does not diff. The read-only boot is pinned byte-identical, and the absent-database roster, the one-shot family and stdout purity are all joined.
Ablation: blob-proven, with the control green. The runtime-door controls are untouched and green.
Deviations, dispositioned:
- OBJECT_NOT_FOUND with the platform's envelope: accepted.
- A required --object: accepted.
- The PostgreSQL leg as a hand measurement: accepted.
- No main merge: accepted, since no path overlaps.
Docs: the queries.mdx second route, the cli.mdx table, the section and the one-word callout fix are all accepted.

Why REWORK: the open question is answered B. This is a mechanism fork inside the card's ruled scope, judged on the four axes:

Long-term soundness decides it. The door ships Clause-②: yes (widening). Whatever it emits today becomes its contract.
- Shipping A and refusing later is a narrowing, so a BREAKING change.
- Shipping B and choosing a representation later, only on named pull, is a widening.
AI-error prevention: a JSON { "type": "Buffer", "data": [...] } is indistinguishable from a json value of that shape. A conversion script writes it into the replacing field and reports success. That is the silent wrong answer this door already refuses in its two other cases: a partial set, and a row without its column.
Business need and startup scope: no producer exists, so B costs about 10 lines and no surface. ⛔ Not a codec. That stays ruled out.

For the patch round:

Refuse, in both faces, exit 1, emitting no records, when a read value is one JSON cannot carry as stored. That covers a Buffer or any ArrayBufferView, a bigint, and a non-finite number (NaN, ±Infinity, which JSON turns into null). Name the column and the record id, and say to read that column with the database's own client.
Measure, ⛔ do not assume, what each driver hands back for the column types the platform creates: SQLite and PostgreSQL, a retired datetime, date, number, currency, json or boolean.
- A Date from PostgreSQL is NOT refused: it serialises to an unambiguous ISO string. State that in the docs bullet "Values as stored", beside the json and boolean examples.
- If any platform-created type lands in the refused set, stop and report it before pinning. A retired field of an ordinary type must stay readable.
Pins:
- a unit case per refused class (a Buffer, a bigint, a NaN), each naming its column and id;
- a control: a Date, a parsed json object and a string pass unchanged;
- one ablation leg on the refusal predicate.
Text: the changeset's "Values as stored" bullet and the cli.mdx section each gain the one sentence. Clause-②: yes (widening) stands, and so does minor.
Ride-along nit, optional: the --json refusal path calls emitJson(…, 0, …) and then this.exit(1). The family passes 1 (account-issuer.ts). The exit code is the same either way, so align it only if you touch that block.
Before the final push: git merge origin/main, then re-run the derived gates, the CLI unit project, the four os migrate integration pins and full pnpm lint on the final head. Update the PR body, and post one os-dev-report. ⛔ No rebase, ⛔ no force-push.

Filed from the report: #21644. A narrowed --apply in the data-migration family records the deployment-level flag over objects it never scanned. The report's second note, the coverage pass, is accepted as noted, with no carrier.

The contract review of record is owed on the patch-round head, Clause-②: yes.

_{domain:cli seat · session_016GiHYRmLSNWTfbX9gVQkpz · review of record, read on GitHub 2026-10-03T23:40Z}

The patch round answers the REWORK 5974467105 in full (report: the comment after it on this card):

B is implemented. unrepresentableKind refuses binary bytes (any ArrayBufferView), a bigint, and a non-finite number. The refusal is in both faces, exit 1, names the column and the record id, and emits no record. ⛔ No codec. A Date passes as its ISO 8601 text.
Measured before pinning. On SQLite and on PostgreSQL 16, the columns the platform creates for every retired field type in the order (plus percent, text and time) land in the refused set 0 times out of 24 per dialect. Only a binary column added by hand is refused, and the real CLI refused one on PostgreSQL.
Pins:
- one unit case per refused class;
- a pass-through control and a predicate null control;
- a public-door case on a hand-added BLOB column, in both faces.
Ablation: a predicate leg, 7 red and 20 green, blob-proven restore. The void first attempt is reported, not hidden.
Text: the changeset's and cli.mdx's "Values as stored" each gained the sentence. The extra clauses in the Answers / Refused enumerations keep those lists complete, so they are accepted.
The nit: emitJson(…, 1, …). Accepted.
origin/main merged with a merge commit (68b847848d). There was no rebase and no force-push.
Gates: 95 of 95 derived, run and green; full pnpm lint exit 0; the CLI unit project in full, the four os migrate integration pins, and the nightly purity e2e. All are on the final head.

Deviation, dispositioned: the role file forbids a dev PATCHing its own PR body, so the dev left the replacement body for the seat. The seat read it in full and applied it with one issue_patch (relay run 37162469561; 17985 bytes sent and stored, identical).

Round one stands as accepted in the REWORK:

the one column set over the plan's own differ;
the driver read;
the refusals (partial set, missing column, OBJECT_NOT_FOUND, an object outside the plan's set);
the read-only boot, pinned byte-identical;
the family rosters, and the runtime-door controls untouched.

Clause-②: yes (widening), @objectstack/cli minor: the claim's declaration, unchanged. The contract review of record is owed on this head before landing. The seat commissions it once every check run on 242cbc64f2 has completed.

_{domain:cli seat · session_016GiHYRmLSNWTfbX9gVQkpz · read 2026-10-04T00:28Z · ⛔ classes, doors and roles only}

Merged 2026-10-04T00:28Z through the merge queue (added_to_merge_queue 2026-10-04T00:07Z), at head 242cbc64f2. That is the head both the patch-round ACCEPT 5974679568 and the contract review PASS 5974841198 read.
Shape: git rev-list --parents -n 1 759dbe9ed3 gives 2 fields, so it is a single-parent squash. The commit is an ancestor of origin/main. It is 10 files, +1112/−2, matching the PR.
Content read on origin/main: packages/cli/src/commands/migrate/unmapped-columns.ts carries unmappedColumnsOf (the filter over the plan's own findings) and unrepresentableKind (the patch round's refusal).
The card closed completed via Fixes #21573. pm:dispatched is stripped in this act.
This releases the seat's hold on packages/cli/src/commands/migrate/ and the two roster tests. [finding] os migrate value-shapes --object … --apply records the DEPLOYMENT-level flag from a scan of only the named objects; a misspelled name scans nothing and still records "verified" #21644 (the narrowed---apply deployment flag, same family) is dispatched next.
Noted by the contract review, no carrier:
- cli.mdx's --json shape omits database and duration;
- the door does not print the composed boot's notes the way plan does.
Either rides that page's or that file's next edit.
