driver-turso remote planMediaColumnMove answers empty, so os migrate files-to-references reports nothing to move on a remote Turso database whose media columns are present

Filing gate: ① a defect with a named landing site, TursoDriver in remote mode inheriting SqlDriver.planMediaColumnMove (packages/drivers/driver-turso/src/turso-driver.ts; the base is in packages/drivers/driver-sql/src/sql-driver.ts). Finding class (a). The same class as #19845 (an inherited Knex schema read answering from the remote placeholder).

Filed by the domain:engine execution seat 1 (session_01TEhopqrWQYBycZzyJHpAZr) from the out-of-scope findings of its #19845 dev (report on #19845). The seat's isolated contract reviewer confirmed it on PR #19891 (record 5797857806, flag ③-1: 「REAL; FILE SEPARATELY」). ⛔ Filed bare: routing and grading are triage's. ⛔ Not a claim.

What happens

SqlDriver.planMediaColumnMove iterates this.managedObjectFields, which the remote face never fills: registerRemoteFieldMetadata goes through registerExternalObject. So a remote TursoDriver answers { plans: [], refusals: [] }.

Measured by the dev on the SQLite double: table m with doc: file and pic: image synced through the batch door, physical TEXT columns present. The remote face gave 0 plans and 0 refusals; the local control gave 2 unquote plans.

Reach

os migrate files-to-references boots through bootSchemaStack WITHOUT deferSchemaDdl, so #19842's remote refusal does not intercept it. It calls stack.driver.planMediaColumnMove() and maps the empty scan to skipped: 'nothing_to_move': a false "nothing to move" for a remote Turso database whose media columns are present. Bounded, per the reviewer: the deployment flag stamp is gated by the data-level backfill and verify self-check, not by the column step, so the result is a wrong report rather than a wrong stamp.

Suggested shape (⛔ not a ruling)

The same first step as #19845 (PR #19891): refuse loudly on the remote face with the transport's NOT_IMPLEMENTED / 501 envelope, so the command says it cannot judge instead of "nothing to move". Real remote introspection is the larger alternative. Check how the command treats a throw before choosing.

Filing-gate answers

Class: ① (defect, named landing site); finding class (a), measured by the dev and confirmed by the seat's reviewer.
Acting reader: the seat that owns packages/drivers/driver-turso after triage routes it (domain:engine); it lands after PR fix(driver-turso): refuse remote schema drift detection instead of answering "no drift" #19891 (same file).
Dedupe, MCP issue search in this repo, closed included: turso remote planMediaColumnMove empty files-to-references remote nothing to move → 1 hit: driver-turso remote mode ignores deferred DDL — os migrate plan against a remote Turso datasource performs the DDL and the canonical backfill it was meant to preview, and prints no pending work #19823 (closed, deferred DDL). Not this defect.

Dedupe words: turso remote planMediaColumnMove empty · files-to-references remote turso nothing to move · remote placeholder knex inherited schema read

Deferred (serial) behind #19893 — stays `pm:queue`, not dispatched this round

Triage's direction (⛔ not a ruling): refuse on the remote face with the transport's NOT_IMPLEMENTED / 501 envelope, as PR fix(driver-turso): refuse remote schema drift detection instead of answering "no drift" #19891 did for drift detection, and read how the migration command handles a throw before touching it.

Fold-or-serial is answered SERIAL on that claim, because gate ① fails: a classifier fall-through there, an empty remote planMediaColumnMove here.

On the transport's SQLite-backed double, all three remote schema doors left managedObjectFields empty and the placeholder Knex without table m, and planMediaColumnMove answered {plans:[],refusals:[]} while the doc/pic TEXT columns were on disk. The local and replica faces planned 2 unquote moves. TursoDriver now overrides planMediaColumnMove: the remote face refuses with the sibling NOT_IMPLEMENTED/501 builder shape (refuseRemoteMediaColumnMove), and local and replica call super unchanged. The command file was in scope by measurement (H2): a thrown refusal reached the outer catch and replaced the whole report with {error,code} and exit 1, after --apply had already recorded the flag. So runColumnStep now catches only a NOT_IMPLEMENTED code as a stated skip, driver_cannot_plan: the text face prints 'Column step: NOT JUDGED' with the driver's message, --json gains columnMoveRefused, and the exit code stays the self-check's.

Claim amendment: `Clause-②` becomes `yes (narrowing)`, and the CLI half of the surface is confirmed

domain:engine#1, session_01Bvd69VPa6puiNzzPUroDBx, written 2026-09-24T18:50Z. It amends claim 5819382636. The branch and the dev are unchanged. It answers the dev's open question in os-dev-report on this card (PR #20014).

Clause-② line: option A. The line is Clause-②: yes (narrowing). The command's --json document gains the key columnMoveRefused. The repo's own precedent reads a new --json key as clause ②: .changeset/17080-per-release-spec-changes.md declares "Clause-②: yes (widening) — … plus one new os validate --json key". The remote planMediaColumnMove refusal is the narrowing. Both packages are graded minor, and the ADR-0087 marker is present. PR fix(driver-turso): refuse media column move planning on the remote face instead of answering "nothing to move" #20014's body and changeset already carry this line, so nothing is edited.
What that triggers at landing: the declaration limb of the clause-② queue gate. Landing needs an at-tier clause-② contract-review PASS on record. The at-tier review owed for the changeset prose covers it in the same record. packages/spec is untouched, so the path limb does not fire, and the card stays in this lane.
File surface: packages/cli/src/commands/migrate/files-to-references.ts and its new test are in scope by measurement, under the claim's conditional arm. On the base, a NOT_IMPLEMENTED from the planner replaced the whole backfill, verify and flag report with {error, code} and exit 1, after --apply had already recorded the flag.

Clause-②: yes (narrowing)

ACCEPT: PR #20014 at `672da75c`

domain:engine#1, session_01Bvd69VPa6puiNzzPUroDBx, written 2026-09-24T19:10Z. Reviewed against references/review-checklist.md on GitHub, not from the dev's report (os-dev-report on this card).

Shape: the first line is Fixes #19894, and the body declares Clause-②: yes (narrowing) (claim amendment 5820204593, option A). The changeset grades @objectstack/driver-turso and @objectstack/cli minor, with one ADR-0087 marker not-required (no-migration-prescription). Fixes #19894 is the only closing keyword.
Scope: 5 files, 592 changed lines, not governed (check-governed-merges --pr 20014), and no generated path. All 5 are inside the claimed surface:
- turso-driver.ts: the remote-face override and its refusal builder only. The constructor guard, detectMode and toKnexConfig are untouched.
- the CLI command files-to-references.ts, put in scope by measurement (H2);
- two new pins;
- the changeset.
- No file moved on main since the merge base.
Contract review of record: PASS at 672da75c (5820491059). It is the at-tier clause-② review the yes declaration requires, and also the prose review of the changeset, the refusal message and the command's new warning line. Every sentence was judged TRUE, and both pins were shown to go red without the fix.
CI at this head: 34 runs, 0 failures, and every required context is success. The skips are Console Pin Gate, Build Docs and Packed-tarball smoke (opt-in), all on the roster.
H4, the ADR-0104 resolveFileColumnsMoved question carried from PR fix(driver-turso): converge remote date/json cells the pre-fix batch door stored unconverted #19904: answered and pinned. A remote TursoDriver never asks the resolver on any of its three schema doors, so fileColumnsMoved stays false, and the driver keeps the JSON encoding. No in-repo route can now stamp a remote database as moved. That capability gap is not filed: nothing today asks for a remote column move, so there is no acting reader.
Out-of-scope findings:
- filed driver-turso README: the remote-transport tree lists beginTransaction, commit, rollback as supported, but the remote face refuses all three with NOT_IMPLEMENTED / 501, and the README names none of the remote refusals #20016: the driver-turso README lists remote beginTransaction, commit and rollback as supported, but the remote face refuses all three with 501;
- noted, not filed: errorCodeFields (packages/cli/src/utils/format.ts) forwards httpStatus and drops status, so a driver refusal in any CLI --json error envelope carries its code without its 501. It is pre-existing and measured, but no consumer that reads status from that envelope could be named, and it is outside this lane (packages/cli utils);
- noted, not filed: a non-refusal throw after an --apply backfill still replaces the report with the error. It is pre-existing and unchanged here, with no named reproduction.
Optional wording, not taken: the reviewer suggested narrowing "null otherwise" to runs that reach the report, and noting that "stays on the JSON encoding" does not cover a database moved out of band. Neither sentence is false.

Landing: ready + auto-merge through the queue.

Landed: PR #20014, verified on `main`

domain:engine#1, session_01Bvd69VPa6puiNzzPUroDBx, written 2026-09-24T19:25Z.

Verified on main: PR fix(driver-turso): refuse media column move planning on the remote face instead of answering "nothing to move" #20014 merged through the merge queue as a0920b42dc. It has one parent and is an ancestor of origin/main after a fresh fetch. refuseRemoteMediaColumnMove has 3 hits in turso-driver.ts at that commit and 0 at its parent, and the command's driver_cannot_plan skip is present. .changeset/19894-turso-remote-media-column-move-refusal.md is on main.
This card: closed completed via Fixes #19894. pm:dispatched was removed in the same act.
Closing keywords: no other lane card was closed by this landing. The PR's only closing keyword named this card.
Serial queue: packages/drivers/driver-turso/src/turso-driver.ts is released, and no engine-lane card is queued behind it.
The next reader of that file is driver-turso README: the remote-transport tree lists beginTransaction, commit, rollback as supported, but the remote face refuses all three with NOT_IMPLEMENTED / 501, and the README names none of the remote refusals #20016 (the README's remote-transport tree, filed from this card's findings; untriaged). It can now list the media-column refusal next to the transaction, auto-number, deferred-DDL and drift-detection refusals.
Carried out of this round: the H4 answer, that a remote TursoDriver never asks the ADR-0104 resolver and keeps the JSON encoding, is pinned in turso-remote-media-column-move-refusal.test.ts. A future remote resolver read turns that pin red.
