fix(ci): register the live background verifier and drop dead v2 exports

[saphid]

Summary

vp run knip:check fails on the v2 branch at the first pass:

Unused files (1)
apps/server/scripts/verify-background-live.ts

That script is not dead code — it is the documented live provider verification entry point (docs/operations/background-verification.md, added in b929c47). Register it as an apps/server knip entry alongside the other runnable scripts (scripts/cli.ts, scripts/probe-claude-fork-local-rollback-replay.ts).

With the file check passing, the exports pass then surfaced two more v2-only knip failures, fixed here instead of ignored:

• autoSettlementSettingsKey (orchestration-v2/ThreadSettlementService.ts) is annotated @internal Exported for tests, but the two unit tests that exercised it on main (ThreadSettlementReactor.test.ts) were lost in the v2 port. Restored both assertions (inherit-vs-never key distinction; unrelated overrides produce the same key) into ThreadSettlementService.test.ts.
• foldUserInputActivities (client-runtime work-log) lost all consumers: the v2 server Orchestrator now attaches questionAnswer to the resolved user_input_request turn item, so web/mobile read workEntry.questionAnswer directly and nothing folds activity arrays client-side. Removed it plus its private helpers, and projectQuestionToolInput in packages/shared/toolActivity.ts, whose only remaining consumer was the fold (its other main-side consumer, ActivityPayloadProjection, does not exist on v2).

Carried shared-CI repairs

This branch also carries two credited cherry-picks so the full check suite passes here; each remains a distinct commit owned by its own PR:

• 77d1d1da — fix(mobile): pin expo-audio so the release smoke patch stays in use (from fix(mobile): pin expo-audio so the release smoke patch stays in use #11518)
• dbb177d2 — fix(mobile): rebuild pending-move fixtures with the shared shell factory (from fix(mobile): rebuild pending-move fixtures with the shared shell factory #11517)

Focused proof

• vp run knip:check — exit 0 (was exit 1 on Unused files; exports pass then also clean)
• vp test run apps/server/src/orchestration-v2/ThreadSettlementService.test.ts — 14/14 pass
• vp test run apps/mobile/src/state/thread-order.test.ts — 5/5 pass
• node scripts/release-smoke.ts — passes
• vp run --filter t3 --filter @t3tools/client-runtime --filter @t3tools/shared typecheck — exit 0
• vp lint + vp fmt --check on touched files — clean
• node apps/server/scripts/verify-background-live.ts --scenario bogus — loads and fails fast on arg validation, confirming the documented invocation runs (a full live run needs real provider credentials and consumes model usage, so it was not exercised here)

Test plan

• vp run knip:check passes
• Focused settlement and thread-order tests pass
• Release smoke passes
• Targeted typecheck/lint/format clean

Approvability

Verdict: Approved at dbb177d

Macroscope's review found this PR approvable — This is a low-risk maintenance PR that removes unreferenced v2 helpers, strengthens tests, registers an existing verifier with Knip, and pins the already-patched expo-audio version for reproducible mobile builds. No product defaults or significant production workflows are changed.

Notes:

• No code objects were reviewed. Approvability was decided on eligibility alone.

[saphid]

@juliusmarminge this OV2 fix repairs the shared knip check and is ready for your review.

Latest head dbb177d28f87 has green CI, is mergeable into t3code/codex-turn-mapping, and has no unresolved review threads. The PR description contains the focused regression evidence. We will keep babysitting it through landing.

Please account for the shared CI dependency commits when landing; the Expo audio repair has already landed through #11518.

[saphid]

Closing: this fix has already landed on t3code/codex-turn-mapping via #11518's squash merge (a8cc38b95b), which had carried this PR's knip repair (plus the thread-order fixture repair from #11517) as credited cherry-picks. Rebased this branch onto the new base and the remaining diff is empty — knip.jsonc registers scripts/verify-background-live.ts, the restored autoSettlementSettingsKey tests, and the dead-code removals are all present upstream.
