This is a pure tooling fix: the argument splitter moves to `src/lib/args.ts` with an explicit VALUE_FLAGS list that now includes `--deadline-minutes` and `--out`, plus a test asserting both are read as value flags and preserving the old fault as contrast. No content/ records, citations, locators, or assessments are touched, and the citation tooling found no identifiers to check. AGENTS.md is untouched, so §3.15's reservation is not engaged. The chain.yml edit only changes how the interrupted-sitting body enumerates run records (from `git diff --cached` to `git show HEAD`) — it does not loosen any §3.15 gate, ratification rule, or provenance stamp; the interrupted body still declares its own absence of an account rather than inventing one. The PR body's admission that #269's cover note over-read the missing account and will be corrected by hand from the run log is an honest disclosure, not a fabricated record. No run account was required since no pipeline runs are carried.

The change fixes argument parsing so `--deadline-minutes` and `--out` retain their values, with a focused regression test covering both the corrected behavior and the prior failure mode. Changing the workflow from an empty post-commit cached diff to `git show ... HEAD` makes the interruption notice enumerate run records actually committed by the sitting, improving rather than weakening provenance and inspectability. It does not edit AGENTS.md, alter content or citations, publish confidential material, or loosen any ratification or fail-closed check.

The proposed change is a clean infrastructure bug fix that factors CLI argument parsing into a pure, tested function (`src/lib/args.ts`) recognizing `--deadline-minutes` and `--out`. It also fixes a git command in `.github/workflows/chain.yml` to accurately inspect committed proposals on interrupted runs. No constitutional rules, content files, or epistemic checks are weakened or violated.

The diff is a pure tooling fix: CLI value-flag parsing is extracted to a tested pure function, and the two flags that were silently dropped (--deadline-minutes, --out) are added to VALUE_FLAGS so a completed sitting can write its account. The chain.yml tweak only adjusts how interrupted-sitting PR bodies list run.yaml paths (git show HEAD vs git diff --cached). No content/, citations, assessments, AGENTS.md, or check-weakening; no run account to audit. Ordinary code repair under §8/§9.

This is a pure tooling fix: the CLI's argument splitter now reads --deadline-minutes and --out as value flags, extracted into a testable pure function with a regression test that deliberately preserves the old fault as a contrast case. No content files under content/ are touched, no citations or locators are added, no AGENTS.md edit appears, and no run records are carried, so the epistemic rules of §3 are not engaged. The workflow change in chain.yml swaps `git diff --cached` for `git show HEAD` when listing run.yaml records for an interrupted-sitting PR body — this surfaces the same or more provenance information (the committed sitting's records) rather than hiding any, so it does not weaken a §3.15 check. Nothing in the diff fabricates provenance or misattributes who did what; the PR body honestly describes the bug, including the operator's manual correction of #269's cover note from the run log, which is a recorded direction rather than a fabricated record.
