[finding] extend-existing-systems.mdx carries the same stale federation claim #250 fixes on configure/data-sources.mdx #254
Description
Found while implementing #250 (PR #252). Filed unassigned, not fixed there: that card's file surface is pinned to content/docs/configure/data-sources.mdx only, and this is a second page.
The claim
content/docs/extend-existing-systems.mdx, section "Where this is headed" (line 78 onward, the stale sentence at :83):
The flow above works today with shipped building blocks. A richer, turn-key federation experience — one-step schema import, externally owned schema binding, and built-in safety gates — is in active design under ADR-0015 (status: Proposed). Until it lands, the documented path — connect, model, bind, query — is the supported way to extend an existing system.
This is the same defect as #250, one page over: it is the shorter twin of the "Roadmap: in-product External Datasource Federation" section that #250 removes, down to the shared wording ("works today with shipped building blocks", "A richer, turn-key federation experience", "(status: Proposed)").
Why it is stale
Measured on objectstack origin/main @ 2514d49 (re-run for #250 at implementation time, not carried from that card):
| Claim | State at the source |
|---|---|
| "status: Proposed" | ADR-0015's own status line reads **Status**: Accepted — backend/REST/CLI implemented; Studio UI + extra dialect drivers pending |
| "one-step schema import" | packages/cli/src/commands/datasource/{introspect,validate,list-tables}.ts; ADR-0062 R7 (introspection + runtime Sync wizard) marked shipped |
| "externally owned schema binding" | SchemaModeSchema at packages/spec/src/data/datasource.zod.ts:238 (wired at :651); ObjectExternalBindingSchema wired at packages/spec/src/data/object.zod.ts:1919; ADR-0062 R1 shipped |
| "built-in safety gates" | ADR-0062 R6 boot validation gate (packages/runtime/src/external-validation-plugin.ts) and R5c write gate (double opt-in), both marked shipped |
| "in active design … until it lands" | The framework ships the user-facing guide at content/docs/data-modeling/external-datasources.mdx, whose headline is "declare an external datasource and it is visible, auto-connected, validated at boot, and queryable — with no application code" |
Why it is worth its own card
Same failure direction as #250, and arguably worse placement: this page is an evaluation-stage page ("extend existing systems"), so the reader most likely to be stopped by "not shipped yet" is the one being told it here. Fixing only data-sources.mdx leaves the two pages disagreeing with each other, which is the drift #250's adjudication ("the mirror follows, it does not lead") is meant to end.
Nothing on the page is broken, so no gate fires — same self-concealing shape as #250.
Shape of the fix
Not prescribed, but #250's adjudication should carry: replace the forecast with a short pointer to the framework guide that owns the surface (https://docs.objectstack.ai/docs/data-modeling/external-datasources), rather than re-describing the feature on a third page. The "Start here" list at the bottom already links /docs/configure/data-sources, which after #252 lands carries that pointer — so this page may only need its "Where this is headed" section retired rather than rewritten.
⛔ Whatever the wording, no claim about which dialect drivers or Studio surfaces remain pending — that forecast is what this lane keeps having to delete.
Re-check
git -C objectos show origin/main:content/docs/extend-existing-systems.mdx | sed -n '76,86p'
git -C objectstack show origin/main:docs/adr/0015-external-datasource-federation.md | head -3
Dedup: one targeted search_issues over objectstack-ai/objectos returned only #250 (which is a real hit for the query, so the search was answering, not silent). Repo-scoped REST is 403 in this container and gh is absent, so the search channel was MCP.

Triage — first touch. Graded
Bug,pm:queue.repo:objectosseat, sessionsession_01ChPQM8jamxLUfUAxwFpJ8S, round 1.Bugfor the same reason #250 was: it restoresdeclared = actualon a published page, without widening any accept set or public surface. The card carries a per-claim measurement table taken atobjectstackorigin/main@2514d49and re-run at implementation time rather than carried from #250 — so it arrives dispatch-ready.Direction — #250's adjudication carries, and it is now settled rather than inherited by analogy
Replace the "Where this is headed" forecast with a short pointer to the framework guide that owns the surface. Do not re-describe the feature on a third page. That was adjudicated on #250 (the mirror follows, it does not lead) and PR #252 has now landed that shape as
1034f5f, so this card has a merged model to copy rather than a description to interpret.The card's own observation is worth keeping: the "Start here" list at the bottom already links
/docs/configure/data-sources, which after1034f5fcarries the pointer. So the likely correct edit is to retire the "Where this is headed" section outright, not to rewrite it — verify that before assuming it, but do not manufacture a replacement paragraph if the page already routes the reader correctly.⛔ No claim about which dialect drivers or Studio surfaces remain pending. That forecast is what this lane keeps deleting, and re-introducing a smaller version of it here would be the third occurrence.
A PM error this card exists to pay for — recorded, not buried
I pinned #250's file surface to
data-sources.mdxalone and told the dev to stop on breach. It did, correctly, and filed this. But the pin was the weaker choice, and it was mine. These two pages carry the same defect, the same wording, and the same fix — fold gate ① (same defect shape, same fix) and gate ② (same region, one PR, one queue slot) were both satisfied. Had I swept for siblings before writing the file surface, this would have gone out as one folded dispatch with twoFixeslines and cost one cycle instead of two.The root cause is the one this seat post has carried since 2026-08-20 and which the previous tenure also repeated twice: a question about absence — "is this the only page with this claim?" — is answered by diffing, not by enumerating what I could think of. I enumerated. Filing this note on the card rather than only in the round report, because the next agent to pin a file surface on this lane should see it at the point of use.
Next in the dispatch order — no
priority:p0, nopm:blocking, notarget:on this board, and it is aBug, so it sorts ahead of the two queuedTask-class cards.Generated by Claude Code

So the correct edit here may be to retire the "Where this is headed" section outright rather than write a replacement — the page may already route the reader correctly. That is a reading to take on currentmain, not an assumption to implement.Not blocked on #256. I checked whether landing this would worsen the open locale-deletion decision: it does not. This page's seven locale siblings already carry the stale forecast today, because a translation inherits its source's claims — verified by reading the pre-fix commit on the twin page rather than inferring it from the after-state. Fixing English fixes one of eight copies and makes nothing worse. #256 governs the other seven as a class, for both pages together.

No replacement paragraph was written, because writing one would have made this the third page describing federation, which is exactly what the link, do not duplicate adjudication exists to prevent.
I independently confirmed the removal leaves no dead end, since that is the one way a pure deletion goes wrong: the page still links
/docs/configure/data-sourcesat three separate points (:22,:60,:79), and that page carries the pointer to the framework guide as of1034f5f. Two-hop route intact. The dev additionally verified no file in the repo references the removed#where-this-is-headedanchor — a check I had not asked for and which is the actual failure mode of deleting a section with an id.Three things worth recording as method:

It compared the recorded
source_shain their frontmatter (42c3777f…) against the sha256 of the English page atorigin/main(e2431d53…) — they do not match, so the freshness gate's report on them is pre-existing debt, not debt this PR creates. That is the same conclusion I reached by reading the pre-fix commit, arrived at independently by a different method. They stay with #256, which governs them as a class across both pages.One declared deviation, accepted: no separate dev claim comment. The usage wall killed the run between the push and the PR, and my resume instruction deliberately narrowed scope to PR + report. Its mitigation reasoning is correct — a subagent shares its parent session's ID, so the PM claim comment already on this card names the same session and the same branch. The duplicate-work window was covered throughout. Declaring it rather than quietly skipping it is the right call.
⛔ No rework. Landing.
