Documents implementation-time findings in the requirements checklist: all
three suspected races were confirmed real then fixed, the ticket-status
mechanism needed no fix, a real pre-existing test-infrastructure issue
(throwaway DB ticket-code collisions at high accumulated volume) was found
and resolved by resetting the throwaway database and replaying its full
migration history, two full-suite-only integration failures were confirmed
as pre-existing cross-file contamination (not a regression), and the
load-test tooling surfaced a real Anthropic API cost consideration for
ticket creation itself. All 23 tasks marked complete.
Full quality gate green: typecheck, lint, architecture check, full unit
suite (119/119), full integration suite against a freshly reset throwaway
database (122/124 — the 2 failures are the project's own already-accepted
MinIO baseline), and all 6 concurrency test files (11/11).

Foundational phase (T002) covers the one shared schema migration US1/US2/US3
depend on; US4 (proof-only, no schema change) and US5 (load-test tooling)
have no dependency on it and can proceed independently.
