# $ca-tribunal — deep codebase audit

The deepest, most expensive review codeArbiter offers, convened rarely and on demand. Routes to the tribunal skill. Eleven lenses judge the codebase; every finding persists to its own file (plus append-only triage/run logs) under `.codearbiter/reports/<run-id>/`, so an interrupted run resumes from disk. Never a required gate — critical/high are blocking-severity findings, not a pipeline halt.

Cost first — this lane routinely costs millions of tokens on a large repo. Phase 0 sizes the codebase, prints a token-cost band, recommends the highest-reasoning model, and STOPs for your acknowledgement before dispatching anything. Nothing runs unacknowledged.

## Flow

Load and follow the tribunal skill ([routines/tribunal/SKILL.md](../../routines/tribunal/SKILL.md)). In brief:

Phase 0 (STOP) — cost estimate, model recommendation, resume check.
Phase 1 (BLOCK) — map the codebase; risk-rank and mark trust boundaries; record AI-authorship markers and iteration depth.
Phase 2 (BLOCK) — dispatch `tribunal-lens-reviewer` once per active lens in priority waves (≤5 in flight); each dispatch writes one file per finding under its own `findings/<lens>/` dir.
Phase 3 (BLOCK) — triage per wave from disk: dedup, independent calibration, decision vocabulary.
Phase 4 (BLOCK) — project the human-readable report from the logs.
Phase 5 (BLOCK) — on explicit selection, file findings as GitHub issues; idempotent against the tracker.
Phase 6 (STOP) — optional, opt-in KPI telemetry to the public codeArbiter repo.

## Arguments

`"scope-path"` — focus the audit on a subtree (default: repository root). The full lens roster still runs; only the scope narrows.

`--tag <label>` — freeform run label recorded in telemetry (see `references/telemetry.md`).

## Routes to

[routines/tribunal/SKILL.md](../../routines/tribunal/SKILL.md) — dispatches `tribunal-lens-reviewer` once per active lens (and, on a large repo, the optional map-structure / map-deps mappers).

## When NOT to use

- A review of the current diff → `$ca-review` (gate-blocking, fast).
- A lean periodic sweep → `$ca-checkpoint` (cheap, frequent; tribunal is its rare, deep counterpart).
- An adversarial STRIDE pass on one sensitive feature → `$ca-threat-model`.
- A governance packet for a window → `$ca-audit`.
- Anything on a schedule or in a hot loop — tribunal is a rare, deliberate, expensive convening, not a routine gate.

## Hard gate

MUST NOT dispatch any lens before you acknowledge the Phase 0 cost estimate. MUST NOT act as a required gate or block a merge/commit. MUST NOT file an issue or send telemetry without explicit authorization. Read-only on project code until the filing gate; findings file as GitHub issues, never the task board.
