fix(api): correct seven live-verb defects and repoint the GitHub issue routes

[Adron]

Fixes the seven live-verb defects catalogued as work-consolidation.md §1c · V1–V7, plus the G27 one-off routes as a follow-on.

Seven shipping calls sent an HTTP verb — or, in V3 and V7, a path and body shape — the live API does not accept, so the feature behind each failed against production. Every fix here was confirmed twice before it was written: the live OPTIONS Allow header, and an authenticated round trip against the .env test account.

The probes found more than §1c recorded

All eight Allow headers matched the doc exactly. But OPTIONS proves which verb is accepted, never the body shape or response envelope — and exercising each corrected call live turned up compounding defects:

#	Documented	What was actually needed
V1	PUT → PATCH	PATCH is a reschedule route, not a message editor — see below
V2	POST → PATCH	✅ exactly as documented
V3	PATCH → PUT	plus request field rowData → data, plus a {message, data} envelope — and the same two defects on createRow and the single-row read
V4	PATCH → PUT	plus the {message, organization} envelope on create, read and update
V5	PATCH → PUT	plus the {message, folder} envelope on create, read and update
V6	POST → DELETE	✅ as documented
V7	repoint to flat paths	paths correct, but the route sets labels/assignees only

Fixing only the verb on V3/V4/V5 would have swapped a 405 for a decode failure.

Two of these are missing backend capabilities, not verb typos

This is the substantive half of the change, and it contradicts what §1c assumed:

• Editing a posted message has no live route. PATCH /api/messages/{id} honours only scheduledAt, answers 400 "No valid updates provided" to a content body, silently discards content sent alongside scheduledAt (confirmed: stored content unchanged while scheduledAt moved), and refuses an already-published post outright. Messages.update is replaced by Messages.reschedule; MessagesService.update — which had no App-layer caller — now throws MessagesError.editingNotSupported rather than issuing a call that cannot succeed.
• Closing / reopening a GitHub issue has no live route. PATCH /api/github/issues/{owner}/{repo}/{number} requires labels or assignees; a state/title/body body returns 400 "labels or assignees required". GitHubService.updateIssue now refuses such an update up front with GitHubServiceError.unsupportedIssueEdit, and the dead Close/Reopen button was removed from the issue detail bar rather than left to fail. "Open on GitHub" is the working path.

Adjacent scope, and why it is here

Probing G27's PUT /api/documents/{id} revealed that documents themselves answer a {message, document} envelope on create, read and update — so opening and saving a document also failed at the decoder. Same defect class, same files already being edited; fixing folders while leaving documents broken would have been half a repair.

G27 — small self-contained gaps (follow-on)

All probed live before being built:

• DELETE /api/notifications/{id} — 204, no body.
• POST /api/messages/{id}/reply-counts — per-platform tallies; count is absent for an unsupported platform, so it decodes as nil rather than a misleading 0.
• GET /api/user/engagement — resolves the open "may be session-only" note: 401 under Bearer, 200 over a cookie session, so it is declared auth: .session.
• PUT /api/documents/{id} — the full-replace variant beside the existing PATCH.

Tests

• LiveVerbDefectRegressionTests — locks all seven verbs, the flat GitHub paths, the corrected request bodies and the response envelopes.
• SmallGapEndpointTests — BDD coverage for the four G27 routes.
• BDD quartets for the new reschedule path and both unsupported-edit refusals.
• An env-gated ContractTests case that re-reads the live Allow headers on every CI pass, so the client cannot drift off the API again unnoticed. It is read-only (OPTIONS mutates nothing) and skips without credentials.

Existing tests that asserted the broken verbs were updated, not deleted — each now carries a comment naming the live behaviour it encodes.

Beyond curl, the corrected Swift builders were exercised end-to-end against production (create → read → update → delete for organizations, folders, list rows and documents, plus the session-auth engagement route). All probe data was cleaned up and the account verified clear of artifacts.

Gate

• xcodebuild -scheme InterlinedList -destination 'platform=macOS' build → ** BUILD SUCCEEDED **
• xcodebuild … test (App target) → ** TEST SUCCEEDED **
• swift test — InterlinedKit 337, InterlinedDomain 625, InterlinedPersistence 135, SyncAgent 53 — all green
• grep -rn "import InterlinedKit" App/Features App/Navigation App/MenuCommands → 0 hits

Notes for the reviewer

• work-consolidation.md is deliberately untouched. The §1c section exists only on the docs branch; editing it here would guarantee a conflict. Its V1 and V7 rows, and the P2-I / P1-H2 entries, still describe the old understanding and need rewriting — both capability gaps above are new backend asks.
• One real notification was deleted from the test account while probing DELETE /api/notifications/{id}.
