datasources: POST /datasources/NAME/test answers an unknown name 200 {ok:false} where every sibling NAME route answers 404 (the #25486 family)

Filing gate: ① a product defect with a reproduction, found by an off-clause probe of QA run #27438 (wave 3 of the 18.3.0 sweep, anchor #27377). reach: measured at the public datasource admin doors.
Business reason: the datasource admin doors disagree on what an unknown name gets back. POST …/NAME/test answers 200 {ok:false} while every sibling route answers 404. An admin tool or script that tests a datasource by name cannot tell "this datasource is down" from "this datasource does not exist".
Reader who acts: the triage seat, then the implementer for packages/services/service-datasource (the admin REST routes).
Dedupe (open AND closed): the query "datasources test unknown name returns 200 ok false instead of 404; datasource test draft creates sqlite file" returned 34 hits. The nearest is #25486 (closed): "three doors answer an unknown resource as empty or bad input … where their siblings answer 404". That is the same family; this door is a fourth instance it did not cover. #27100 (closed) changed this door's message after a failed connect, not the unknown-name status.

Batch-of: 16 · QA run #27438

Symptom

POST /api/v1/datasources/NAME/test answers an unknown name with 200 {ok:false} where its sibling routes answer 404.

Reproduction (subject `c4c515a`, scratch copy of the showcase, admin)

POST /api/v1/datasources/nope/test → 200 {ok:false, error:"[ObjectQL] Datasource 'nope' has no registered driver to introspect."}
GET /api/v1/datasources/nope, PATCH …/nope and the other :name routes → 404 RESOURCE_NOT_FOUND.

Expected: 404 RESOURCE_NOT_FOUND for an unknown saved name, the same as the siblings. {ok:false} should be kept for a datasource that exists and fails its probe.

⛔ Not a claim.

Read fresh. POST /datasources/NAME/test answers an unknown name 200 {ok:false} while every sibling :name route answers 404. A door disagrees with its siblings (the rest: three doors answer an unknown resource as empty or bad input (publish-drafts 200, flow runs 200 [], datasource PATCH 400) where their siblings answer 404 #25486 family): p2.
Resolve the saved name with the lookup the sibling routes use and answer RESOURCE_NOT_FOUND. Keep {ok:false} for a datasource that exists and fails its probe.

Domain: domain:server
Seat: domain:server#1
Ruling-ref: triage 6495190501: resolve the saved name with the lookup the sibling routes use and answer RESOURCE_NOT_FOUND; keep {ok:false} for a datasource that exists and fails its probe.
File surface: packages/services/service-datasource/src/admin-routes.ts and/or external-datasource-service.ts, a test beside the existing datasource-test suites, datasource-route-ledger.ts only if its :name/test note states what the route answers (with its conformance test), one changeset (stop on breach; explain in the report)
Container & model: S, mode:subagent (general-purpose subagent loading .claude/agents/os-dev.md as its role file), model: TIER_DEFAULT (dispatch-gates --tier: no path-derived mandate), effort: medium
Clause-②: no
Metadata-protocol: none
Responsibility: POST /datasources/NAME/test answers an unknown name 200 {ok:false} where GET/PATCH/DELETE /datasources/NAME answer 404 | a caller or the console reads a typo as "connection failed" | any change to the admin datasource routes
Thread-read: 6495190501
Premise: holds (read at origin/main aef631b80b: admin-routes.ts:756-766 calls testConnection(name) with no existence check; testConnection catches every error into {ok:false}; GET /:name answers 404 at admin-routes.ts:749). Two cautions carried into the order: the primary datasource (default) may have no metadata record (#24772) and must still be testable; remote-tables and object-draft answer 400 for an unknown name, a separate discrepancy, out of scope here.
Serial constraints cleared: no open PR touches the service-datasource admin routes or service (all 24 open PRs' file lists read).

  "premise_still_valid": true,
  "summary": "The premise holds at base d4ff1a025f: the Test door called testConnection(name) without checking that the name exists, and testConnection caught every error into ok:false. ExternalDatasourceService.testConnection now reads the stored record first through getDatasource. That is the same metadata.get('datasource', name) read that the sibling doors' getDatasourceRecord makes. When nothing is stored, it throws a 404 RESOURCE_NOT_FOUND error in GET's words, and the existing badRequest relay in admin-routes.ts answers it as GET /datasources/NAME does, so the route handler is unchanged. The primary datasource (default) is exempt by name and is still probed by its live driver with or without a stored record. A saved datasource that fails its probe keeps 200 {ok:false}. FILE-SURFACE EXTENSION (the claim names no existing test files): five existing pins in primary-datasource-test-and-sync.test.ts and saved-datasource-test-after-failed-connect.test.ts tested 'a saved datasource with no live driver' under a name with no stored record. Two of them hit /ghost/test over HTTP and so pinned this exact defect, which means any fix turns them red. Their assertions are unchanged; each fixture now stores that datasource's record. The seat should amend the claim's file surface to cover these two files. Not touched: datasource-route-ledger.ts, because its :name/test note does not state what the route answers. The worktree at /home/claude/objectstack-issue-27510 is left in place, clean and pushed, for the seat to remove.",

Ablation via scripts/ablation-replace.mjs in wrap mode (the subject is imported from src by a relative path, so no dist is involved): A1 replaced the guard with 'if (false ...)' and gave '2 failed | 3 passed (5)', both unknown-name cases.

Claim amendment: declaration and file surface · 2026-10-29T13:35Z
Clause-②: no (narrowing). The claim's no was the seat's error. POST /datasources/NAME/test answered an unknown name 200 {ok:false} and now refuses it with 404 RESOURCE_NOT_FOUND. A request that was answered 200 is now refused, which is a narrowing of a REST door. The precedent is exact: #26801 (6279efef6f, security explain refuses a userId with no sys_user record with 404) declared no (narrowing) with a ! title. Owed now: a ! title, the changeset's **BREAKING** banner and ADR-0087 marker (level stays patch, since Metadata-protocol: none), the dogfood battery, a Skills-docs: line, and one CONTRACT_REVIEW_TIER review run by the seat before the queue.
File surface (added): packages/services/service-datasource/src/__tests__/primary-datasource-test-and-sync.test.ts and saved-datasource-test-after-failed-connect.test.ts, fixture records only. Two of their pins drove /ghost/test over HTTP and so pinned this defect; their assertions are unchanged.
The rest of the claim stands.
