$ca-doctor — install health

Silent dormancy is the worst failure shape this plugin has: the gates look installed but never fire. This command proves the active host is healthy and reports every non-OK finding with an exact remediation.

Flow

The mechanical report also invokes the installation-pinned artifact client's `capabilities` operation. When the repository contains an HTML authority, it performs a bounded catalog read to surface invalid or ambiguous artifacts. It MUST NOT load the artifact schema, search `PATH`, use a repository binary, mutate an artifact, or silently fall back to Markdown. Its executing-adapter identity comes from the already admitted plugin root. The observed adapter manifest version is separate from the native helper manifest's declared version and the native executable digest verified by the on-demand capability probe. A newer cached sibling is not the executing version. Missing or malformed identity data is reported as unknown; it never grants package trust.

• `CAPABILITY_MISSING` or another installation identity failure is unhealthy: report “repair or

reinstall the pinned artifact payload; HTML work is blocked.” Unrelated legacy Markdown remains usable.

• An invalid HTML artifact is unhealthy: preserve the bounded engine code and direct the user to

inspect `repair-preview` before any explicit reviewed repair. 1. Resolve the plugin root from this loaded skill path, then run its `hooks/doctor.py` with Python 3 and present the report verbatim. Do not try an empty plugin-root environment variable first. 2. In an arbiter-enabled repo, attempt `git add --all --dry-run` via the shell tool. `[H-03]` means hooks are firing; execution means **CRITICAL: gates dormant**.

Remediation ladder

1. Restart Codex so hooks register at session start. 2. Remove and re-add `ca-codex@codearbiter`, then approve the changed hook set in `/hooks`. 3. If dormancy was intended, `$ca-init` opts the repository in.

When NOT to use

• Scaffold state only → `$ca-init --check`.
• Project progress, not install health → `$ca-status`.

Hard gate

Read-only. MUST NOT create markers, stage files, grant trust, weaken a block, or retry the live-fire probe with different spelling. MUST surface a failed probe as CRITICAL, never as a footnote.

For an arbiter-enabled repository, the mechanical report treats the Git backstop as healthy only after exact managed-shim and live-enforcer validation, plus a harmless selected-Git `git hook run pre-push` probe with empty input. It never executes a foreign hook.
