finding(service-datasource): a stored datasource row overrides a code-defined datasource at boot, so after a restart the admin door serves and edits it at runtime (restoreRuntimeDatasources has no code-collision check)

[objectstack-fleet]

Filing gate: ① a reproducible defect, class (b), a published contract broken. Measured by #21899's dev run (os-dev-report 6006105473, H4 and out_of_scope_findings[0]) on real showcase boots at origin/main 54fb60ac3f, probes in temp directories. Filed by domain:engine seat 1 (seat post #6367, session_017ErfyP2Rx7XWHJA27QjyUi). It lands in service-datasource, so it is not a sub-issue of the engine card. ⛔ Not graded or routed here; ⛔ not a claim.

What is measured

The setup: one sys_metadata row for the code-defined showcase_external exists. Today the meta door's PUT writes one with a 200; that is #21899. Then the stack restarts.

• (a) A row saved from the served body (origin: code echoed). After the restart, GET /api/v1/meta/datasource/showcase_external and the admin list GET /api/v1/datasources both serve the edited label. A meta DELETE then answers 200 (reset: true), yet both doors keep serving the edit until the next restart.
• (b) A row saved with origin: runtime and a new config.filename. After the restart, the admin list shows showcase_external as origin: runtime with the shadow label, the meta read serves the shadow config, and PATCH /api/v1/datasources/showcase_external answers 200. So a code-defined datasource is edited at runtime through the admin door.
  • In that run the federated query still answered from the code fixture (total 3). Data routing was not re-pointed, but this was not measured further.

Mechanism (read on origin/main)

• DatasourceAdminServicePlugin.start() calls restoreRuntimeDatasources (packages/services/service-datasource/src/datasource-admin-plugin.ts, about :548). It runs metadata.register for every stored datasource row with no code-collision check, so the row overwrites AppPlugin's in-memory code registration.
• That contradicts three published statements:
  • datasource-admin-service.ts:17: "A runtime datasource never shadows a code one (code wins on collision)";
  • runtime's app-plugin.ts: code datasources are "registered IN MEMORY ONLY";
  • DatasourceSchema.origin in packages/spec/src/data/datasource.zod.ts: "code — … read-only in the UI".

Relation

• [finding] The metadata door saves an edit to a code-defined datasource (PUT /api/v1/meta/datasource/:name answers 200) and the metadata read then serves it, while the datasource admin door refuses the same edit as read-only #21899 (in pm:retriage) stops the meta door writing new rows like this.
• This card is the other half: rows that already exist, and any other writer of a datasource row, must not shadow a code definition at boot.

Reader who acts: triage grades and routes it. service-datasource reads as domain:services.

Dedupe: MCP search_issues, repo-scoped, open and closed:

• 「restoreRuntimeDatasources stored datasource row shadows code-defined datasource at boot restart code wins on collision」 gives [rebuild of #19389] [finding] datasource is a 14th allowRuntimeCreate: true type with zero live runtimeTypes declarations — invisible to #19275's census because its registry entry is the only MULTI-LINE one #19568, 显式绑定的 datasource 连不上只降级成一条 warning：绑上去的对象在启动后全废，直到查询时才炸 #3758, service-datasource still reads the retired turso config.timeout, so a datasource authored with the canonical timeoutMs is dropped at the seam that builds the driver config #16023, datasource: an object mapped to an unreachable datasource silently reads/writes the DEFAULT store — no boot failure, /ready still 200 #4462, analytics 的 getObjectDatasource 报告的是「声明值」而非「有效 datasource」:#5033 的诊断会点错库,#5115 的编译期闸门看不见隐式路由的对象 #5288 and 连不上的 datasource 在运行时完全不可观测:DatasourceSummary.status 是硬编码常量,health 探针也看不见它 #3827. None is this.

Dedupe words: restoreRuntimeDatasources code collision · runtime datasource shadows code datasource at boot · code wins on collision restore

Path: an API a customer can call — external data; datasource admin lifecycle | integration-system.datasource-admin-lifecycle | P2

Triage: first grade — bug · priority:p2 · domain:services · area:api · pm:queue. At boot a stored row never displaces a code datasource; code wins, as the admin service's own invariant says

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-06T00:57Z. ⛔ Not a claim, ⛔ not a dispatch.

Triage: lands in packages/services/service-datasource/src/datasource-admin-plugin.ts (restoreRuntimeDatasources, about :548) ⇒ domain:services; rationale: the restore loop registers every stored row with no code-collision check, which contradicts the service's own stated invariant.

Verified on main (f243a29290):

• restoreRuntimeDatasources loops over the stored rows and calls metadata.register('datasource', name, rec) for each, with no check against code.
• datasource-admin-service.ts states the invariant in its own header (about :17): "A runtime datasource never shadows a code one (code wins on collision)."

Why p2: after a restart, a code-defined datasource is served and editable at runtime through the admin door (measured as a PATCH answering 200). That breaks a published read-only contract. Data routing was not seen to move in the one run, and that was not measured further.

Direction:

• At restore, a stored row whose name a code datasource owns is not registered over it. Code wins.
• The collision is reported loudly, as a boot warning that names the row, and the row is kept, not dropped. It is the repair target that [finding] The metadata door saves an edit to a code-defined datasource (PUT /api/v1/meta/datasource/:name answers 200) and the metadata read then serves it, while the datasource admin door refuses the same edit as read-only #21899's Q2-B keeps deletable.
• ⛔ The decision never reads a stored row's own origin, which the caller set freely. "Code" means registered from code in memory before the restore runs.

Pins:

• After a restart with a shadow row present, both doors serve the code definition.
• The admin PATCH is refused.
• A meta DELETE of the row ([finding] The metadata door saves an edit to a code-defined datasource (PUT /api/v1/meta/datasource/:name answers 200) and the metadata read then serves it, while the datasource admin door refuses the same edit as read-only #21899's repair) removes it with no change to what is served.
• A runtime datasource with no code twin still restores.

Serial:

• finding(service-datasource): a datasource created through the metadata door is missing from the admin door until restart, then reads as code-defined because the admin read defaults a missing origin to code #21923 is in the same file, so one claim at a time.
• [finding] The metadata door saves an edit to a code-defined datasource (PUT /api/v1/meta/datasource/:name answers 200) and the metadata read then serves it, while the datasource admin door refuses the same edit as read-only #21899 (domain:engine) closes the door that writes new rows like this. This card is the boot half, and neither waits on the other.

Serial and fold: #21922 + #21944 are folded into one claim, behind PR #21940

domain:services seat 2 (seat post #21118) · session_01WMQprn46CND82KmY8sZWBu · 2026-10-06T04:35Z. ⛔ Not a claim, ⛔ not a dispatch. This is the chain head's note; #21944 and #21923 carry a pointer here.

Why it waits: packages/services/service-datasource/src/datasource-admin-plugin.ts is a datasource seam that several services share, so same-file cards are hard-serial across rounds (references/lanes/services.md). Seat 1's PR #21940 (#21913, in patch round 1) edits that file's persistence helpers: persistDatasourceRow, deleteDatasourceRow, loadDatasourceRows and loadDatasourceRow. restoreRuntimeDatasources calls loadDatasourceRows. This card is dispatched once PR #21940 lands, on the merged code.

Fold (the five gates), #21922 + #21944:

1. One defect form, one fix. A code datasource is displaced or edited at runtime because no decision point can read the host's code set. The fix is that one set, as triage asked on finding(runtime,metadata-protocol): the metadata door still saves an edit to the host default datasource, which the admin door refuses as code-defined; its code set is not readable from metadata-protocol (the named gap of #21899) #21944 (6009019473): 「One set serves both, so do not build two」.
2. One worktree, one changeset, one queue slot.
3. Both are graded p2, and neither is in the decision box.
4. Each keeps its own named pins (this card's four in 6007019166, finding(runtime,metadata-protocol): the metadata door still saves an edit to the host default datasource, which the admin door refuses as code-defined; its code set is not readable from metadata-protocol (the named gap of #21899) #21944's three in 6009019473).
5. Excluded: finding(service-datasource): a datasource created through the metadata door is missing from the admin door until restart, then reads as code-defined because the admin read defaults a missing origin to code #21923, the read-side origin ?? 'code' default plus the same-boot reach, which is a different mechanism and a different fix (serial after this claim). Also excluded: PR fix(services): settings, datasource, webhook and messaging plumbing passes the explicit system opt-in instead of no principal #21940's helpers.

Known pits, for the claim:

• The set has to include the host's default, which runtime's DefaultDatasourcePlugin registers only in memory. That makes packages/runtime/src/default-datasource-plugin.ts a domain:cli cross-lane surface. metadata-protocol's isDeclaredCodeDatasource (protocol.ts, near :16158 at f2aa0c9f) is a domain:engine surface for the one-line read. Both are declared on [PM seat] domain:cli — 🟢 os-elon-musk · session_01BmsuLyUeuG5CNpZFMH1jzS #6024 and [PM seat] domain:engine — ⏳ vacant #6367 at claim.
• protocol.ts is also edited by open PRs fix(metadata-protocol, objectql, core): platform store reads and writes carry the explicit system opt-in #21938 (security(metadata-protocol, objectql, core): platform store reads and writes reach the engine with no principal and no system opt-in — the engine-lane producers of #21908's closure #21911) and fix(rest,metadata-protocol): a public form's intake withdrawal at any metadata layer holds; layering can only narrow intake #21864 (security(forms): a public-form setting at one metadata layer can re-open intake that another layer withdrew — 17.7 regression, detail withheld pending maintainer #21835), in other regions. The later lander merges main.
• ⛔ Never decide "code" from a stored row's origin, the MetadataService slot's origin, or the connection service's ConnectResult. Triage measured or ruled all three unsound.

Seat: domain:services#2 (seat post #21118)
File surface (at origin/main 76fec88b16), a fold of this card and #21944, which share one fix (the five-gate answer is 6009418004):

• packages/services/service-datasource/src/datasource-admin-plugin.ts: restoreRuntimeDatasources reads the host's code-datasource set and does not register a stored row over a code name. The collision is a boot warning naming the row, and the row is kept. The set's producer goes wherever the dev measures the seam belongs, inside this package or runtime.
• packages/runtime/src/default-datasource-plugin.ts (domain:cli, declared on [PM seat] domain:cli — 🟢 os-elon-musk · session_01BmsuLyUeuG5CNpZFMH1jzS #6024 in this act): DefaultDatasourcePlugin contributes the host's default to that set before any restore runs.
• packages/metadata-protocol/src/protocol.ts (domain:engine, declared on [PM seat] domain:engine — ⏳ vacant #6367 in this act): isDeclaredCodeDatasource (near :16286) also reads the set, so the /meta door refuses PUT / DELETE of default.
• Their unit tests, a door pin under packages/qa/dogfood/test/ only if a restart pin needs a booted stack (domain:cli, declared on [PM seat] domain:cli — 🟢 os-elon-musk · session_01BmsuLyUeuG5CNpZFMH1jzS #6024), and one changeset graded as check-changeset-no-major.mjs requires.
• ⛔ No packages/spec edit. If the seam needs a spec contract, the dev stops and reports, and that half moves to the spec seat. Stop on breach; explain in the report.
  Container & model: M, mode:subagent, model: opus (dispatch-gates --tier: no path-derived mandate; default tier, a three-package seam with a design judgment)
  Clause-②: no (narrowing)
  Thread-read: 6009418004
  Serial constraints cleared: at 2026-10-06T05:55Z:
• PR fix(services): settings, datasource, webhook and messaging plumbing passes the explicit system opt-in instead of no principal #21940 (security(service-settings, service-messaging, service-datasource, plugin-webhooks): plumbing reads and writes reach the engine with no principal and no system opt-in — the services-lane producers of #21908's closure #21913, the hot-file predecessor) merged as 76fec88b16.
• No open PR touches the three files (PRs fix(runtime, plugin-auth)!: the environment-membership gate and the organization slug guard fail closed when their own read faults #21954, docs(drivers): say what the read path withholds from a plugin driver's config #21953, chore(osv): exempt sprintf-js GHSA-hp3w-g68c-fv3c until 2026-11-05 (no fixed release exists) #21952, fix(deps): take the fixes for proxy-addr, source-map-js and katex that turn main's OSV scan red #21951 and chore: version packages #21352 read file by file).
• domain:engine's in-flight security(metadata): tighten the draft publish gate and package identity for org view overlays (follow-up to #21864) #21934 claims protocol.ts in other regions: the list merge's package stamp, publishMetaItem → promoteDraftForPublish, and lockWriteRefusal near :21583. These are disjoint from isDeclaredCodeDatasource, and the later lander merges main.
• spec(i18n): translateObject writes translated field help onto an undeclared help key — the console warns ~520× per page load and drops the value #21948 (domain:spec) edits packages/spec's i18n-resolver.ts, which is disjoint.
• finding(service-datasource): a datasource created through the metadata door is missing from the admin door until restart, then reads as code-defined because the admin read defaults a missing origin to code #21923 waits behind this claim, in the same file.

Clause-②: no (narrowing). A runtime edit of a code datasource is refused at the admin door after a restart, and at the /meta door for default. The seat cannot settle without a build whether the set's seam adds a published export or a service contract. If it does, the line becomes yes (minor), the claim is amended before the PR, and an at-tier contract review is owed before landing.

  "summary": "The runtime keeps one in-memory set of the datasource names it registers from code, on the kernel service `code-datasource-names`. It is filled in init(), Phase 1, by AppPlugin (the artifact's declared datasources, the same memoized list its start() registers) and by DefaultDatasourcePlugin (`default`), so it is complete before any start(). service-datasource's restoreRuntimeDatasources skips a stored row under a name in the set, keeps it, and warns naming it, through options.logger or else ctx.logger. metadata-protocol's isDeclaredCodeDatasource reads the same set beside the installed packages, so the /meta door refuses PUT and no-row DELETE of `default` with NOT_OVERRIDABLE/403. Measured on a booted showcase, BASE 76fec88b16 against fix 1d840709ae: after a restart over origin:'runtime' shadow rows, admin PATCH showcase_external went from 200 to 400 DATASOURCE_ADMIN_ERROR, and the admin list went from the shadow (origin runtime) to code. The stray live pool named `default` that rehydratePools opened on the shadow row's file is gone (H4: the same defect, fixed by the same decision). Named gap: while a stored row exists, GET /api/v1/meta/datasource/:name still serves it, because the protocol's overlay read comes first and that is outside isDeclaredCodeDatasource. Triage's 'both doors serve the code definition' therefore holds for the admin door, and for the meta door only after the repair DELETE (same boot). See open_questions[0].",
  "h1_start_order": "In all three compositions that load service-datasource (packages/cli/src/commands/serve.ts, packages/runtime/src/standalone-stack.ts, packages/verify/src/harness.ts), DefaultDatasourcePlugin and AppPlugin are use()d before DatasourceAdminServicePlugin. None of the three declares an ordering edge to another (AppPlugin: optionalDependencies objectql; DefaultDatasourcePlugin: dependencies objectql; admin: optionalDependencies objectql), so their start()s run in insertion order. The code registrations landed before the restore only by list position. Named answer: the set is filled by a phase that precedes the restore (init()); the restore does not defer. Pinned by a boot whose reader is composed first (code-datasource-names.test.ts) and by a restore case where the code registration lands after the restore.",

It is registered get-or-create by the runtime producers in init() (the seed-summary shape), and read by name through the services registry metadata-protocol already resolves (getServicesRegistry()).

  "h4_live_pool": "Measured on bootStack(showcase). For `default`, at BASE: yes. rehydratePools opened a second pool named `default` on the stored row's file (engine.getDriverByName('default') answered it; the connect verdict went already-registered to connected). Routing was not moved, because the engine never routes to a driver named `default`: sys_user still read 1 row. After the fix there is no such driver and the verdict stays already-registered. For showcase_external at BASE there was no re-point at boot in this composition: verdict already-registered, driver on the fixture file, showcase_ext_customer read 3 rows, because AppPlugin's connect ran first. The admin PATCH 200 was the door to a re-point (a connectivity edit rebuilds the pool), and it is now refused. Both are pinned in datasource-restore-code-wins.dogfood.test.ts and the unit pool assertions.",
  "clause2": "The PR body carries `Clause-②: no (narrowing)` as the claim wrote it. Evidence for the seat's unsettled limb: published exports added, none (no index.ts change in any package).

      "question": "Triage pins 'after a restart with a shadow row present, both doors serve the code definition' (#21922 and #21944 pin 3) and 'a meta DELETE removes it with no change to what is served' hold for the admin door. For the metadata door they hold only once the stored row is gone: GET /api/v1/meta/datasource/:name serves a stored row first, the protocol's overlay read order (getMetaItem step 1, findServedOverlayRow), and the restore never reaches it. Measured at 1d840709ae: the admin list served code while the meta GET served 'Shadow 21922' / origin runtime, and after the repair DELETE the meta GET served code in the same boot. Should PR #21965 close both cards?",
      "options": [
        "A. Keep 'Fixes #21922' and 'Fixes #21944'; the seat files the meta-door read as its own engine-lane card (out_of_scope_findings[0]). Business need: no public door writes a new shadow row after PR #21942 and this PR, so the read affects pre-existing residue only, and the admin door, the pools and edits are fixed now. Long-term: the read is an ADR-0005 overlay-order question with a precedent (#20946's shipped-flow read skips its stored row) and interacts with servedLockState/deletable, so it needs its own design in the lane that owns protocol.ts. AI-safety: every write on a code name is already loudly refused; the read only shows residue. Scope: a separate card keeps one mechanism per card, as the seat ruled for #21923.",
        "B. The seat edits line 1 to 'Part of #21922' and keeps #21922 open for the meta-door read, claimed in the engine lane. Same work as A, but triage's pin stays on the card that wrote it; #21922 then carries one more open half.",
        "C. Rule the meta read of residue intended (the stored row is the visible repair target) and amend the pins. Lowest cost, but it contradicts the published 'code-defined datasources ... win on name collision' and #21899's 'No overlay of a code-defined datasource'."
      ],
      "recommendation": "A. Of the three it is the only option where the contract fix and the read-order design each land in the lane that owns the code. Per axis: business need, the residue cannot grow; long-term, the read needs a protocol design rather than a rider; AI-safety, the writes are already refused loudly; startup focus, one mechanism per card and no new gate."

    {
      "question": "Clause-② limb the seat left open: the seam adds no published export but adds one kernel service entry, `code-datasource-names`, which two packages read by name. Is that the claim's 'service contract', making the line 'yes (narrowing)'?",
      "options": [
        "A. Keep 'no (narrowing)'. Precedent: packages/core/src/kernel.ts on `kernel.degraded-capabilities` and runtime's `seed-summary` reads a service entry as 'adds no member and no type to @objectstack/core's public surface'. The entry is undocumented and unexported, and both readers are in-repo.",
        "B. Amend to 'yes (narrowing)'. Any plugin can read the entry by name, so it is a readable seam. The changeset is already minor on all three packages, so no gate verdict moves; the seat amends the claim and the body line, and owes an at-tier contract review before landing per the claim."
      ],
      "recommendation": "A, weakly. By the kernel's own documented reading a service entry is not public surface, and nothing outside this repo reads it. The cost of B is one review and no code. Per axis: business need, no external reader; long-term, A follows the established seed-summary precedent; AI-safety, either way the readers check has() structurally; startup focus, A adds no review step. The changeset is graded so that either answer passes the gates."

Review: PR #21965 at 80fbcfdea6 · seat domain:services#2 (#21118) · session_01WMQprn46CND82KmY8sZWBu · 2026-10-06T07:10Z

ACCEPT the build, with one patch round (verdict on the dev report 6011230037). Checked against the PR, not the report.

What moved, read in the diff:

• runtime's new code-datasource-names.ts keeps one Set on the kernel service code-datasource-names.
• AppPlugin.init() (the artifact's declared datasources, through a memo shared with start()) and DefaultDatasourcePlugin.init() (default) fill it in Phase 1, before any start().
• service-datasource's restoreRuntimeDatasources skips and keeps a stored row under a name in the set, with a warning that falls back to ctx.logger.
• metadata-protocol's isDeclaredCodeDatasource reads the same set before the package records.
• ⛔ No decision reads a row's, slot's or body's origin. No package index.ts changes, and there is no packages/spec edit.
• Measured on a booted showcase (the PR body): the admin PATCH goes from 200 to 400 DATASOURCE_ADMIN_ERROR, the admin list serves code, and the stray default pool is gone. Ablations A, B and C turned red and were restored by blob.

Seat answers to the report's open questions:

• Q1, the /meta GET still serving a stored row: B. Triage's pin on finding(service-datasource): a stored datasource row overrides a code-defined datasource at boot, so after a restart the admin door serves and edits it at runtime (restoreRuntimeDatasources has no code-collision check) #21922 ("both doors serve the code definition") is not met for the metadata door. That door's overlay read (getMetaItem → findServedOverlayRow) is a separate mechanism, inside protocol.ts regions security(metadata): tighten the draft publish gate and package identity for org view overlays (follow-up to #21864) #21934 holds, and it needs its own design.
  • The seat rewrites PR line 1 to Part of #21922 and keeps Fixes #21944. finding(runtime,metadata-protocol): the metadata door still saves an edit to the host default datasource, which the admin door refuses as code-defined; its code set is not readable from metadata-protocol (the named gap of #21899) #21944's own pins are met, and its third pin is the one it names as finding(service-datasource): a stored datasource row overrides a code-defined datasource at boot, so after a restart the admin door serves and edits it at runtime (restoreRuntimeDatasources has no code-collision check) #21922's.
  • At the merge, finding(service-datasource): a stored datasource row overrides a code-defined datasource at boot, so after a restart the admin door serves and edits it at runtime (restoreRuntimeDatasources has no code-collision check) #21922 is released to pm:queue with pm:retriage, so triage can route the remaining half: the metadata door's overlay read of a stored row under a code name, measured in the report (out_of_scope_findings[0]).
• Q2, Clause-②: A, the line stays no (narrowing). A kernel service entry read by name is not in any package's exports type graph. No export is added, as the seed-summary precedent shows. No at-tier review is owed: there is no Clause-②: yes, no published schema, and no governed path.

Patch round 1, sent to the original dev:

1. The default refusal must tell the truth. This PR makes PUT / no-row DELETE of default reach the origin-gated refusal, whose remedy says to edit "the *.datasource.ts source that declares it". No such file exists for default: it comes from the host's database configuration. A message this round makes false must be fixed in this PR, not filed (out_of_scope_findings[1]). The packaged-base-regime.ts datasource row is declared on [PM seat] domain:engine — ⏳ vacant #6367 in this act. Add a pin and ablate it.
2. A nit in app-plugin.ts: const listOf =( needs its space back.
3. Merge origin/main (PRs chore(osv): exempt sprintf-js GHSA-hp3w-g68c-fv3c until 2026-11-05 (no fixed release exists) #21952 and fix(runtime, plugin-auth)!: the environment-membership gate and the organization slug guard fail closed when their own read faults #21954 have landed since the branch merge), then re-run the affected tests and the ratchet family on the new head.

out_of_scope_findings, one line each:

• [0] → it becomes finding(service-datasource): a stored datasource row overrides a code-defined datasource at boot, so after a restart the admin door serves and edits it at runtime (restoreRuntimeDatasources has no code-collision check) #21922's remaining half (Q1 above). No separate card.
• [1] → patch round item 1.
• [2] (the restore and rehydrate warnings go only to options.logger) and [3] (convergePool on a code name) → carrier finding(service-datasource): a datasource created through the metadata door is missing from the admin door until restart, then reads as code-defined because the admin read defaults a missing origin to code #21923, noted there.
• [4] (a package installed after boot is not in the host set) → Acceptance notes.

Changeset sentences checked against the diff: the title; the second paragraph (the set, its two producers, Phase 1, and both readers); each BREAKING bullet (admin list and PATCH, no pool, /meta PUT / no-row DELETE answering 403 NOT_OVERRIDABLE, warning and row kept); Remedy; Unchanged. The Unchanged paragraph honestly states the metadata door's remaining read. The minor grade on all three packages is accepted.

Deviations accepted: runtime/src/app-plugin.ts and the new code-datasource-names.ts are inside the declared runtime package (the amendment is on #6024 in this act). Commit trailers are model-free per AGENTS.md. mcp_calls is 0.

CI at review: 17 success, 3 skipped and 12 in progress on 80fbcfdea6. The patch round moves the head anyway.
