Real app-created projects and Codex gpt-6.1-sol turns. No transcript contents or usage timestamps fabricated.
For the age cutoff, changed one completed task-owned transcript file mtime to 120 days ago.
Temporarily moved that file outside the provider scan directory to exercise transcript cleanup.
Restored that original file and its original mtime afterward.
Main: server.updateSettings({patch:{usageHistoryRetentionDays:365}}) returned Success but omitted the setting.
Main: cache did not retain the 120-day-mtime real transcript despite requested 365 days.
PR: authenticated server.getUsageSummary({sinceDay:"2020-01-01",untilDay:"2026-11-10",timeZone:"UTC",awaitRefresh:true}) and server.updateSettings via actual WebSocket API.

Real responses rendered in web client: RETENTION_MAIN_OK, RETENTION_PR_OK, RETENTION_AFTER_SETTINGS_OK.
Usage tokens and 90-day selector remained usable after retention changes and restart.
125 focused tests passed on Blacksmith.
vp run check:changed 3fa57b92a238cdd8e079af925b673b2f99618b98 passed on Blacksmith: format, lint, knip, graphql, typecheck (36 packages), 160 tests.
The initial check command lacked history on the snapshot worker; fetched the exact head at depth 2 and reran successfully.
No source changes, commits, or pushes.
Unverified: Cursor external API/backfill, real Claude transcript cleanup, live retention races, native mobile/desktop, relay/tunnel.
The proxy supports real Codex turns but its account rate-limit read returns JSON-RPC -32600.
