attest completed — Stage 4 ceremony presented per the canonical foundation+heavy template; operator witnessed the value narrative naming the cadence-doctrine-without-runnable-surface gap closure, the byte-equal vendor-mirror sync diff, the REQ→@covers parity gate at 6/6 (100.0%), and the GHI #400 waiver-path frontmatter discipline. All ARB receipts cited inline: lint clean (arb-ruff-fdc95ce9a7464c98b33fb565882eb4b5), typecheck clean (arb-step-typecheck-e750b859a7994859a971b73040f9c54f), full unittest 4223/4223 (arb-step-unittest-a3f6656f2aca41d18e2989ef34804cc3), OBPI-scoped 21/21 (arb-step-unittest-b223c18801d64682be415c2bec0a22fb), mkdocs strict clean (arb-step-mkdocs-69a374b405b045ba9abf25ef41e86802), behave heavy-lane clean (arb-step-behave-7a4b86f8152341e6b520eef3b507beb4).
