chore: #508 follow-ups — scoped session invalidation + stale fallow publicPackages entry

[omridevk]

Follow-ups from the #354/#508 investigation.

Scoped session invalidation

invalidateSessions() invalidated the whole sessions router key, so every pane add/close/new-session also refetched the root chrome's warm sessions.resolve query — pure waste, since that query keys off the latest session row and refetches on its own when the row changes (and resolveRow is idempotent for a given id). Now scoped to sessions.list.key().

Evidence via the #508 real-core test infra: mount + split + close previously produced 3 sessions/resolve wire calls, now 1 (the add-pane mutation's own mint). New regression test in quick-add-pane.browser.test.tsx fails at expected 3 to be 1 against the old code.

Inventory backing the narrowing: all 10 invalidateSessions() call sites are "the session list changed"; the only two queries under the sessions router key are sessions.list and the warm resolve.

Stale fallow publicPackages entry

@conciv/harness-testkit is private: true and absent from the publish guard, but .fallowrc.json listed it as public — suppressing unused-export findings (this is how the orphaned export in #508 went unnoticed). Entry removed; the two findings it surfaced (renderedMessages, snapshotText in run-events.ts — in-file callers only) are now module-private. No other private package is wrongly listed.

Evidence

@conciv/app 143/143 (real Chromium), harness-testkit/extension-testkit suites, @conciv/embed 114 ITs, whole-repo typecheck, lint, format, fallow audit zero introduced, changeset coverage (@conciv/embed: patch).

📝 Walkthrough

Walkthrough

The change scopes widget session invalidation to the sessions list, adds warmed-session browser coverage, and removes two harness helpers from public exports and the public package allowlist.

Changes

Scoped session invalidation

Layer / File(s)	Summary
Session list invalidation and browser coverage apps/conciv/src/data/app-data.ts, apps/conciv/test/quick-add-pane.browser.test.tsx, .changeset/scoped-session-invalidation.md	invalidateSessions now targets the sessions list query. The browser test verifies pane addition and closure without repeated session resolution after warm-up. The changeset records a patch release for @conciv/embed.

Harness package visibility

Layer / File(s)	Summary
Internal harness helpers and package allowlist packages/harness-testkit/src/run-events.ts, .fallowrc.json	renderedMessages and snapshotText are no longer exported. @conciv/harness-testkit is removed from the public package allowlist.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 5edee

The PR narrows session refreshes and removes a stale package visibility entry without introducing an actionable merge-blocking risk; it is merge-ready after normal checks and review.
