Pull request overview
This PR closes out OpenSpec change isolated-branch-stack-browser-e2e task 4.3 on a clean, freshly-fetched origin/main history, superseding the noisy #496 (whose CRLF whole-file rewrites had inflated the diff past the review cap). It marks task 4.3 (rerun of the existing test-agent-governance-check.ps1 dead-link/line-count gate) complete using already-recorded 2026-08-11 evidence, and reconciles the lifecycle ledger accordingly. It is purely governance/docs bookkeeping — no runtime code changes — and honestly leaves tasks 5.2/5.3 open, blocked by the existing A4 IFC-ready gap.
Changes:
- Marks tasks.md task 4.3
[x]with an evidence note referencing the 2026-08-11 gate run at HEAD7929d74(45 pass / 0 fail). - Reconciles the lifecycle ledger for this change from 30/33 to 31/33, updates

L1-TG-001[medium] 4.3 completion is based on a test run from a different commit than this PR head — SHA mismatch alone does not establish a test gap. Task 4.3 specifically verifies that the earlier 1.1–1.3 documentation changes did not break the governance gate, and the recorded run states that commit 7929d74 contained those changes. This PR changes only tasks.md and lifecycle-ledger.json; the difL1-TG-002[medium] Ledger advances verified counts without evidence tied to the final ledger state — 此 finding 混淆了「被驗證的 subject commit」與「寫入驗證結果的 ledger commit」。cb9edf...正是勾選 4.3 的內容 commit；後續f2f31b...只負責將該結果對帳進 ledger，因此指向前者合理。要求 ledger 內的subject_commit等於最終 HEAD 會形成不可滿足的自我引用：修改欄位後 commit SHA 又會改變。供應的 diff 也呈現一致對帳：只有一項任務由未完成變完成，completed相應由 30 增至 31，current_slice同樣記為 31/33 並列出兩個剩餘任務L1-CORRECTNESS-001[low] Ledger subject_commit records a different commit than the stated verification subject — The finding assumes an unsupported contract: thatsubject_commitmust equal the revision on which every cited verification command ran. The diff suggests otherwise.

The lifecycle ledger only carries a compact state summary, while the task line records the actual 4.3 verification context. The EOL/stale-checkout note is tied to the same gate rerun a
Summary
No findings survive to the L3 gate, so there is no blocking issue to report from this review chain. Maintainers may proceed based on this adjudication, subject to their normal validation of the recorded evidence.
