$ca-audit — promotion packet

Everything codeArbiter logs, it logs append-only and scattered: overrides.log, triage.log, decisions/, sprint-log.md, checkpoints/. This command assembles them into the one document a team lead, compliance reviewer, or auditor actually asks for: what happened in this window, who authorized it, and what is still open. Read-only over every source; its only write is the packet.

Window

• <from-ref> <to-ref> — two tags/SHAs (e.g. v1.2.0 v1.3.0).
• --since-checkpoint — from the last-checkpoint record to HEAD.
• --since <date> — ISO date to HEAD.
• No argument → from the most recent tag to HEAD (no tags → last checkpoint; neither → BLOCK and ask for an explicit window).

Flow

1. Resolve the window to a commit range and a time range; both appear in the packet header.
2. Gather, citing each source file:
   • Commits — git log over the range, grouped by Conventional-Commit type; merge commits listed with their PR reference.
   • Overrides — every overrides.log line in the time range, verbatim (including SECURITY-OVERRIDE and DEV: entries), each with its BY: identity.
   • Triage — every small-lane classification in triage.log in range.
   • Decisions — ADRs created or superseded in range (from decisions/ file dates and the supersede chains), each with its Decided-by attribution.
   • Sprint auto-decisions — entries from sprint-log.md in range; list every low-confidence entry verbatim, count the high ones.
   • Open questions — all currently-unresolved [CONFIRM-NN] items.
   • Checkpoint findings — from the most recent checkpoints/*.md: findings still open.
3. Write the packet to <project-root>/.codearbiter/audits/<YYYY-MM-DD>.md (second run the same day appends -2, -3, … — an existing packet is never overwritten). Surface the path and a three-line summary: commits, overrides, open items.

Hard gate

Read-only over every source — MUST NOT modify any log, decision, or checkpoint while assembling. MUST NOT overwrite an existing packet. MUST quote override and low-confidence sprint entries verbatim — never paraphrase an audit line. An empty section is stated as empty, never omitted — "no overrides in window" is itself the finding.

When NOT to use

• Live project state right now → $ca-status.
• Triggering reviews → $ca-checkpoint (this command only reports what reviews already found).
