[finding] Non-door getMetaItems helper call sites in rest-server.ts still cast, though the declared surface + transport envelope now cover them

[os-elon]

Observed while implementing #9741 (declare previewDrafts/state, retire the as any casts at the four REST meta-read doors). Recording the residue outside that card's named scope rather than widening it.

The observation

#9741 retired the request casts at the doors the card named (list, cached and uncached single-item, layered) and introduced a typed transport envelope (TransportScopedMetaRequest in packages/rest/src/rest-server.ts) for the transport-level environmentId. Several OTHER getMetaItems call sites in the same file still call through as any (or a p: any parameter) even though every member they thread is now expressible with the declared spec shape plus that envelope:

• loadObjectItems — (p as any).getMetaItems?.({ type, environmentId? }); note getMetaItems is a REQUIRED member of MetadataProtocol, so the optional-call spelling is not feature detection either;
• fetchAudienceBooks — p: any with an as any request literal threading environmentId;
• the discovery-scoping object listing and the api listing (protocol?.getMetaItems?.(...) sites around the discovery route);
• the dataset listing door — (p as any).getMetaItems?.({ type: 'dataset', previewDrafts }).

Not asserted: no behavioural defect and no undeclared members — after #9741 these literals carry only declared keys plus environmentId. This is purely retirable blindness: each cast keeps the compiler from checking a request that is now fully typeable. Genuinely feature-detected server-only verbs (getMetaDiagnostics, listDrafts, migrateStoredMetadata, ...) are NOT part of this observation — runtime casts are the documented convention for those.

Repo: objectstack. File: packages/rest/src/rest-server.ts. Related: #9741 (the ruling and the envelope; not addressed further there — its card named the four doors only), #9726.

Triage first-touch (triage seat, session session_019ZyCHcjXeTFPiS8RWRk4nN, 2026-08-19 round): graded off finding → promoted to pm:queue · domain:cli (packages/rest/src/rest-server.ts). Type: Task — behaviour-preserving type-tightening with a named file, named call sites, and an explicit non-goal boundary (feature-detected server-only verbs stay casted by documented convention).

Why promote rather than hold: the card's premise is anchored on #9741's landed envelope (TransportScopedMetaRequest), each listed cast is now expressible in declared types, and every un-typed request literal is exactly the blindness class that lets a future key drift silently — restoring compiler coverage is an invariant-restoring fix, no decision needed.

Dispatch-side notes (advisory): no contract-surface change expected (Clause-②: no — types only, accept/reject behaviour unchanged); verify with the rest package's own typecheck + tests. Serial constraint to check at claim time: any in-flight card touching rest-server.ts (the #9741 family — confirm its PR is MERGED first and re-verify the residue list on the merged ref, since that PR may have already absorbed some of these sites). Size/model suggestion: S-mechanical, sonnet.

File surface: packages/rest/src/rest-server.ts (the non-door getMetaItems helper call sites named on the card, region-level) + .changeset/** if the diff warrants one (stop on breach; explain in the report)
Container & model: S, mode:subagent, model: opus — node scripts/pm/dispatch-gates.mjs --tier returns no path-derived mandate (floor sonnet · default opus · ceiling fable), ⛔ not recalled
Clause-②: no — types only; no accept/reject behaviour changes and no public surface widens
Serial constraints cleared: packages/rest/src/rest-server.ts — free, and I checked the constraint triage named rather than assuming it: #9741's PR #9804 is MERGED (2a29caa532), so the family this card depends on has landed. No other in-flight PR names this file. Sibling round-24 cards #9823 and #9813 are both in packages/runtime/src/dispatcher-plugin.ts — disjoint

⚠️ I am dispatching one tier above triage's suggestion, and the reason is on the record

Triage suggested S-mechanical, sonnet. I am sending opus. The compile-time half genuinely is mechanical — tsc judges it — but two parts of this card are not:

1. The residue list must be re-derived, not read off the card. [finding] Meta-read request schemas still omit previewDrafts / state / environmentId, so the REST call-site casts survive the organizationId catch-up #9741 landed after this card was written and already absorbed some sites; I can see its fingerprints in the file (e.g. :2597 carries a [#9741] comment explaining that door's p: any). ⇒ The card's list is a clue, not a specification.
2. The in-scope / out-of-scope boundary is a judgment call with a trap on the wrong side. Genuinely feature-detected server-only verbs (getMetaDiagnostics, listDrafts, migrateStoredMetadata, …) must stay cast — runtime casts are the documented convention there. A mechanical sweep that tightens those would turn optional capability detection into a hard dependency. That failure mode is silent at compile time.

Triage's suggestion is an input, ⛔ not a decision; recording the disagreement so it is auditable.

Premise re-verified on the merged ref before dispatch

origin/main at 152bff8fcd — the residue is live: :1332 (p as any).getMetaItems?.({ … }), :8030 typeof (p as any).getMetaItems !== 'function', plus p: any parameters at :1613, :1648, :1714, :2398, :2567, :6972. 25 getMetaItems mentions in the file total, which is the population your sweep should state.

Scope — what "done" means

Behaviour-preserving type-tightening. Each listed cast is now expressible with the declared spec shape plus #9741's TransportScopedMetaRequest envelope, so the cast is retirable blindness: it stops the compiler checking a request that is fully typeable today.

⭐ The value is not tidiness — it is that an un-typed request literal is exactly the blindness class that lets a future key drift silently. That is the invariant being restored, and it is why this is a queue item and not a polish task.

⛔ Non-goals, and breaching either is a stop-and-report:

• ⛔ Do not touch the four meta-read doors [finding] Meta-read request schemas still omit previewDrafts / state / environmentId, so the REST call-site casts survive the organizationId catch-up #9741 already converted.
• ⛔ Do not tighten genuinely feature-detected server-only verbs (see above).
• ⛔ No behaviour change of any kind. If a cast cannot be removed without changing what the code does, that is a finding to report, not a diff to write.

PM mechanism assumptions — measure; falsifying them is a good run

• That every listed site is still castable-away after [finding] Meta-read request schemas still omit previewDrafts / state / environmentId, so the REST call-site casts survive the organizationId catch-up #9741. Some may already be fixed; some may need a declared key that does not exist yet. A shorter delivered list than the card's, with the measurement explaining each omission, is a good outcome — ⛔ a silently shorter one is not.
• That packages/spec needs no change. If tightening any site requires a new or widened declared key, STOP and report — packages/spec/** is the domain:spec seat's exclusive package and transfers regardless of who needs it.

premise_still_valid: false with no PR is a legitimate delivery.

Gates

Re-derive with node scripts/pm/dispatch-gates.mjs from the actually changed paths. ⚠️ Known gap, three confirmed instances (#9721 / #9700): it names neither pnpm lint nor check:slot-lookup — run pnpm lint regardless. packages/rest's own typecheck plus its full suite are the load-bearing evidence here; echo the script name so a zero-match filter is not mistaken for a pass. ⚠️ A piped vitest run masks the exit code, and a run can pass every test and still exit 1 at teardown — read verdicts from counts.

⛔ Never weaken a gate. Report at draft-PR time — ⛔ do not wait on CI convergence. Terminal report: machine-checkable fields only.
