docs: record the fourth 2026-09-03 block (#2440, #2445, #2427) and refresh v0.3.0 readiness

[Chris0Jeky]

Summary

Records shipped reality that docs/STATUS.md was missing after the last coordination cycle, and refreshes the v0.3.0 readiness view against the current main.

• New "fourth block" in STATUS for the three merges since 01d77faf3: PR #2440 (Smart CI error-receipt control identity, closes #2401), PR #2445 (interrupted transient Review poll streak reset, #2214), PR #2427 (required E2E decoupled from the Windows Frontend Unit leg, #2378 partial). The open-PR "not shipped reality" list is refreshed.
• docs/releases/V0_3_0_READINESS.md: measured head moved to 7d8deef12; the #2378 clause-4 note records what #2427 changed and what stays open; the section-H inconsistency now points at the Q1 recommendation posted on #2337 and states it is not a ruling.

Verification

• node scripts/check-docs-governance.mjs: passed.
• Merge SHAs and PR numbers were read from the live GitHub PRs, not from memory.

Not verified: nothing executable changes in this PR.

Human-action file

Reconciled with current main at edf5b5e (merge commit, no rebase).

The four conflict hunks in docs/releases/V0_3_0_READINESS.md were all superseded by the newer measurements PR #2462 already landed on main (clause 4 green at cca2db2, the Q1 = A ruling, #1972 moved to v0.5, #2334 counted in section 2). Main's side was kept for each. The residual PR diff is the fourth-block record in docs/STATUS.md plus one readiness line about PR #2427, both docs-only.

Proof: node scripts/check-docs-governance.mjs passed. Docs-only, so the review gate is a clean automatic Codex outcome; merging after exact-head CI and the aging window.

Fresh-context independent review at edf5b5e (docs-only; used because the Codex connector reported its review quota exhausted on this head).

CRITICAL/HIGH: none. The fourth block is contiguous with the third (01d77fa to 7d8deef), the #2427 statements in STATUS and the readiness doc agree on scope and merge SHA, #2378 stays partial, and nothing claims a roadmap item shipped.

LOW, wording only, not fixed here: the readiness line sits under clause-4 'can take main red' but describes a skipped-counts-as-green hazard; the branch-protection remark in STATUS is stated as rationale, not a measured check.

Merging after exact-head CI and the aging window.
