feat: Gremlin chaos adapter + arch-gate governance#2
Merged
Conversation
Arms an architectural-invariant contract on anvil (previously the only DeploySignal-family repo without one) and a PR gate that enforces it: - arch-invariants.json / .baseline.json — no-god-functions (ts, complexity ≤12), no-god-files (≤500), no-secrets, and self-guard (the meta-ratchet: the config itself can't be relaxed to pass). - .github/workflows/arch-gate.yml — runs the gate (public sprag) on every PR and blocks on a violation or a rule relaxation. No dependency on private tooling. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Mirrors the Chaos Mesh split — pure translation separated from the network call:
- adapters/gremlin-translate.ts — pure, network-free translateGremlinAttack(attack, now).
Table-driven attack-type taxonomy (latency/blackhole/packet_loss → network_*; cpu/memory
→ *_stress; shutdown/process_killer → pod_*; time_travel → time_skew; unknown →
gremlin_<type>), attack.length → recovery_seconds; throws on a missing/zero fault window.
- adapters/gremlin.ts — fetchExpectedFailurePattern / fetchChaosExperimentContext now GET
/v1/attacks/{ref} via an injectable FetchLike client (defaults to globalThis.fetch), then
delegate to the translator. fetchDeployContext/emitVerdict remain stubs.
- test/q29-gremlin-translation.test.ts — a case per attack-type mapping, missing/zero-length
throws, and a fetch test with a fake client (URL + auth headers, non-2xx rejection).
The classifier is a taxonomy lookup (not an 8-case switch) so cyclomatic complexity stays
under the gate's limit by construction — the no-god-functions invariant never had to fire.
+14 tests (45 total green); the arch-gate passes.

Finishes the Gremlin chaos-platform adapter (was a v1 stub) and arms anvil with an architectural-invariant gate.
What's here
translateGremlinAttack(network-free) split from the network call, mirroring the Chaos Mesh pattern;fetchExpectedFailurePatternGETs/v1/attacks/{ref}via an injectable fetch client. +14 tests (45 total, green).arch-invariants.json(no-god-functions/files, no-secrets, self-guard meta-ratchet) + a PR gate (.github/workflows/arch-gate.yml) that runs the public sprag engine and blocks on a violation or a rule relaxation.Note
This PR was built under its own gate: the classifier is a taxonomy lookup (not an 8-case switch) so complexity stays under the
no-god-functionslimit by construction. The arch-gate check on this PR is the gate enforcing itself.🤖 Generated with Claude Code
