Reran the E1.2 validator against the exact T2.2 manifest/results with --allow-docs-tip: E12 VALIDATOR PASS, exit 0.
Reviewed the bound W01 matrix: 64/64 PASS, including all prior 28 cases, teacher scope, direct-ID/filter/count, homeroom scope, term atomicity, overlap, foreign profile, RPC read/write/create/unlink, and DB before/after assertions.
Independent live scope probe: disposable faculty-4 session was absent from faculty-3 teacher list; temporary records were removed.
Independent live atomicity probe: invalid out-of-year term returned validation error and no named year row remained; temporary records were removed.
Reran T0/T1 regressions: Core parity, Core nav UX, route surface (0 unregistered protected blockers), package topology, package consistency, and package catalog all PASS.
