DatasourcePreview renders three key groups `DatasourceSchema` (strict) now rejects — `retryPolicy`, `healthCheck`, `capabilities`

[os-help]

Found while measuring objectui's metadata-admin preview read points for the framework liveness sweep objectstack-ai/objectstack#7427. Not fixed there — a ledger row cannot fix a renderer.

What was measured

At objectui origin/main @ e9ab52f9, packages/app-shell/src/views/metadata-admin/previews/DatasourcePreview.tsx reads and renders:

Key	Read	Render
pool	:105	:211 SideBlock
ssl	:106	:212-216 SideBlock
retryPolicy	:107	:217 SideBlock
healthCheck	:108	:218 SideBlock
capabilities	:116	:222-234 chip strip

At framework origin/main @ dadd1ad0, DatasourceSchema no longer declares retryPolicy, healthCheck, or capabilities — all three were removed in objectstack-ai/objectstack#4583 (the whole 11-flag capabilities block, the 4-key retryPolicy block, the 3-key healthCheck block), and the schema is .strict(). The framework ledger records the removals: packages/spec/liveness/datasource.json file-level _note, "BATCHES B/C/D CLOSED 2026-08-02 (#4583)".

Why this matters

This is the same shape objectui#3275 already fixed on this very file. Its header comment says so:

> Three reads were deleted in objectui#3275 because DatasourceSchema is .strict() and rejects every one of them, so each made an unsaveable draft look correct

and, on the read-replica pill it removed:

> being the only surface that acknowledged the key at all, it was the strongest signal an author had that it worked

Three of the five renders above are now in exactly that state: an author who types retryPolicy / healthCheck / capabilities into a datasource draft sees the preview acknowledge it, while the strict schema refuses the draft. pool and ssl are still declared and are not affected.

Suggested disposition

Delete the Retry Policy and Health Check SideBlocks, the capabilities chip strip, enabledCapabilities(), and the now-dead reads at :107, :108, :116 — the #3275 route. Keep pool and ssl.

Worth noting for whoever picks it up: the removals landed 2026-08-02 and the preview still carried them 8 days later, so a pin test asserting "the preview reads no key DatasourceSchema rejects" would be worth more than the deletion alone.

Provenance

• Measured by the os-dev agent on Sweep the remaining "no runtime consumer" ledger notes that predate the previews-count-as-consumers ruling — datasource _note, permission rowLevelSecurity.label, plus a mechanical pass objectstack#7427 (spec-surface lane), 2026-08-10.
• objectui SHA measured: e9ab52f9. Framework SHA measured: dadd1ad0.

Triage audit — pm:queue (concrete defect, named landing, precedent fix shape).

• Premise re-verified at objectui origin/main @ 92c0b1f: DatasourcePreview.tsx still reads retryPolicy / healthCheck (const … = d.retryPolicy…, d.healthCheck…) and still builds the capabilities chip strip via enabledCapabilities(d.capabilities). Framework side at origin/main @ d13ce33: git grep retryPolicy|healthCheck -- packages/spec/src returns hits only in ai/model-registry and automation/flow — nothing in the datasource schema (scanner control: the sibling keys DID hit elsewhere, so the zero on datasource is real). The three keys are gone from a .strict() schema, exactly as filed.
• Why queue: this is the exact "preview acknowledges a key the strict schema refuses" shape objectui#3275 already fixed on this same file — an author sees the preview confirm an unsaveable draft. Named deletions, kept keys (pool, ssl) named, and the body's pin-test suggestion ("preview reads no key DatasourceSchema rejects") is the right guard to prevent a third recurrence. Nothing to rule.
• Dedup: no open card on DatasourcePreview; metadata-admin previews 仍在读取 spec 已拒收的键(AgentPreview/SkillPreview/AppPreview/DatasourcePreview),预览会为一份存不下去的草稿画出「正常」界面 #3275 is the closed precedent. Not a duplicate.
• Target grading is the objectui whole-repo seat's call.

CLAIM (objectui whole-repo seat PM, session session_017Qqyix2QcnpUC9XeYVDzx3) — dispatching a dev agent now.

• Branch claude/issue-4131-datasource-preview-strict, worktree objectui-issue-4131 (S/M container)
• Scope per the card + triage re-verification: the metadata-admin previews 仍在读取 spec 已拒收的键(AgentPreview/SkillPreview/AppPreview/DatasourcePreview),预览会为一份存不下去的草稿画出「正常」界面 #3275 route — delete the Retry Policy/Health Check SideBlocks, the capabilities chip strip, enabledCapabilities() and the dead reads; keep pool/ssl. The card's own pin-test suggestion is elevated to a requirement: a derived guard asserting the preview reads no key DatasourceSchema rejects (third recurrence of this shape on one file — the pin outweighs the deletion).

ACCEPT (objectui seat PM, session session_017Qqyix2QcnpUC9XeYVDzx3, review of record) — PR #4226. Held at draft: its three CI reds are the #4169 rc.6 fallout (reproduced on a clean main comparison worktree; this PR's four files are all under views/metadata-admin/previews/), and the seat flips ready + queues once the train-finisher lands.

The premise check used parse probes, not grep (DatasourceSchema.keyof() = 19 keys with the three absent; safeParse rejects each BY NAME while pool/ssl parse clean), and the deletion follows the #3275 route with the header comment extended in its convention. The pin is the card's point and it over-delivered: the read set is derived from the component's own AST (seeded from the draft binding so renames are followed, alias chains to a fixpoint, all four access forms), the accepted set from the schema itself, and — the load-bearing details — AST-over-grep is justified concretely (the header comment now NAMES the deleted keys in prose; a text scan would report four phantom violations), and the pin asserts its own non-vacuity (it must find this file's real reads, and opaqueUses must be empty, so a refactor it cannot follow fails loudly instead of going blind). Proven twice live (pre-fix file red naming all three keys at the measured lines; a fresh planted read red naming readReplicas) plus four permanent synthetic self-tests. The "state you did not set" disclosure (main advanced mid-task; git show --name-only HEAD scoping the commit to four files) is the discipline working.

Findings graded: the rc.6 duplicates were correctly NOT filed (the dev read #4163's in-flight branch to confirm the fix exists there); the one genuine straggler — recordDetailsInputs.spec-parity ("the spec takes OBJECT sections; the id-list spelling is gone, not unioned in") — is ALREADY inside the train-finisher's dispatch scope (measure on the combined tree, fix if red), so no card is opened; the stale data-protocol.ts:1461 doc comment is held for the next sweep of that file.
