Document the standalone interfaces, timing checker, FIFO pressure cases,
tool-component identity and exact execution commands. Update subsystem
guides and the verification ledger with the matching ICS55/IHP130 evidence.
Keep historical failures and producer identities separate from the new
results. Record the optional PDF-test skip, unconstrained IO boundaries,
deferred full-product regressions and the human phase-acceptance gate.
Validation: 21 local links and the documentation-only post-test delta
checked; git diff --check passed. No generated evidence is committed.
