Exact-state disclosure

The originally reviewed corrective commit ac08e258aafe554383cc88552a167d1b65fc98bb became unavailable after the disposable review sandbox expired. Its independently reviewed tree remained preserved and reproducible.

This PR uses a controlled metadata-only replacement commit. The content is unchanged:

• replacement head: 5cbbb9965a03da41a08fd17a8dec3e03f2b62029
• original parent: 629451385f0d2a92fb9b414d1ee97a93560814bb
• independently reviewed tree: c9969892b6eaa841745cade4dba53ccbdad1f6d4
• exact base-to-head patch SHA-256: 154c4528f96a915a63116a540e8853427ff78a2b0c1b8f725f47077cee4714b7
• replacement raw commit payload: 346 bytes, SHA-256 9ed14833d6060b75173d1bb1238f7952c7d4c08005ab41987938317fa6dc68c2

The publication sandbox imported and hash-verified both exact commit objects, reproduced the reviewed tree and patch byte-for-byte, verified the two-file scope, trailers and ordering, clean worktree, and remote head.

Cleared validation evidence

• focused tooling suite: 18/18 passing
• full Node suite: 421/421 passing
• full TUI suite: 91/91 passing with Bun 1.2.21 and OPENTUI_LIBC=musl
• remediation contracts: 7/7 passing
• repair validation: 50 scripts, 0 blockers
• production dependency audit: 0 vulnerabilities
• canonical package, syntax, and git diff --check gates passed
• independent corrective review cleared at 96% confidence

Browser residual boundary

The author’s exact-tree live browser checks passed at 1440×900 and 390×844. Operator’s independent review sandbox did not include a supported browser, so the second review exercised the same DOM/JavaScript paths with isolated VM probes and source/computed-rule assertions instead of a second live browser session.
