Learn about vigilant mode.

Auto-released from merge of PR #940 (trigger: pull_request).

  • Lock-step tightened: per-model prompt variants get a single source of truth, a bake gate, and doctor coverage (dario#lock-step). Three loosenesses in the mechanism that keeps dario's per-model system prompts (fable / opus-5 / sonnet-5) byte-aligned with CC's:
    • One table drives everything. The variant families lived in two hand-maintained lists — VARIANT_MODELS in scripts/capture-and-bake.mjs and the hardcoded selection arms in systemPromptForModel — the exact divergence class that shipped tool_names ≠ tools twice. Both now derive from VARIANT_FAMILIES (src/live-fingerprint.ts, next to TEMPLATE_BASE_MODEL for the same reason): key, capture model, and matcher in one place, matcher-precedence order preserved (fable before the bounded -5 arms). test/template-invariants.mjs asserts the shipped bundle against the table — every family carried and distinct from the base, no orphan variant keys — so a divergence can no longer ship quietly.
    • The bake refuses to ship silent variant loss. A variant capture that failed with no previous variant to keep used to log a warning and bake anyway — the bundle would then serve that family the shared base prompt with no other symptom, and in --check the absence masqueraded as "N → 0 chars" variant drift, handing the watch workflow a rebake PR that strips the variant. That outcome is now exit 1 (infra failure, same philosophy as the older-CC guard from #635), with --allow-missing-variant as the deliberate bypass. Captured-and-matches-base still passes — that's a measured result, and a genuine variant retirement remains reportable drift. Kept-previous variants now log a note that the kept text may lag the freshly captured base.
    • Degraded lock-step is visible at runtime. describeTemplate (doctor's Template row + the proxy startup line) now appends variant coverage (variants: fable+opus-5+sonnet-5 / variants: none), and dario doctor gains a "Prompt variants" row: ok when every family in the table is carried by the loaded template, warn naming the missing families — the state a variant-less bundle or a pre-variants live cache shadowing the bundle used to reach invisibly (requests still 200, wrong prompt).

Built + tested + npm-published inline by cc-drift-auto-release.yml on this run — tokenless via OIDC trusted publishing, provenance-attested. See the workflow log for the publish output.
