May 2026 13:42:04 -0500 Subject: [PATCH 018/124] docs: reconcile examples-smoke claim ledger to repo-wide Python CI Documents that `.github/workflows/tests.yml` already covers the offline examples smoke via `python/tests/test_examples_smoke.py`. Removes the stale "no examples smoke CI yet" claim from examples/docs. Adds an offline/no-key examples-smoke regression test for checked-in mission fixtures. The live-provider framework quickstarts remain opt-in/manual.

Complexity check: + - SQLite implementation path would likely touch more than 8 files and introduce migrations/state compatibility. Smell triggered.

Existing code that already solves sub-problems: + - `python/vibap/lineage_budget.py` provides `LineageBudgetLedger` plus concrete `FileLineageBudgetLedger` with `fcntl`-locked JSON snapshots and idempotent reservation/release/reject semantics. + - `python/tests/test_lineage_budget.py` already covers reservation success, oversubscription failure, reload/crash persistence, idempotent duplicate delegation request IDs, release, reject, and concurrent sibling reservations. + - `python/vibap/passport.py::MissionPassport.from_dict` rejects unknown mission fields, so `/issue` already fails closed on raw `lineage_budgets` in a passport-shaped payload. + - `python/vibap/mission_compile.py` has the existing loud-failure pattern: `MissionPolicyNotImplementedError` for unsupported non-empty `effect_policies` and `flow_policies`. + +2. Minimum change that satisfies the task: + - Add a failing test that `compile_mission(lineage_budgets=...)` raises `MissionPolicyNotImplementedError` with a Phase 1 deferred message. + - Add a failing HTTP issuance test that `/issue` with `lineage_budgets` returns 400 and says the field is unsupported/Phase 1 deferred, rather than issuing a token. + - Implement the smallest compiler/passport gate needed to produce that explicit failure. + - Update `STATUS.md`, `site/data/claims.json`, and source-backed docs/mirrors only where claims could overread as mission-declared lineage budget enforcement. + +3. Complexity check: + - SQLite implementation path would likely touch more than 8 files and introduce migrations/state compatibility. Smell triggered. Defer. + - Explicit defer path should touch roughly 5 to 7 files: tests, compiler/passport/error path, status/claim docs, and checkpoint/handoff docs if needed. Right-sized. + +4. Search/check-local note: + - No external architecture search is needed. This is not a new storage/concurrency design if we choose defer. For the existing ledger, the boring built-in path is Python JSON + `fcntl.flock`, already implemented and tested. + +5. TODOs: + - No tracked `TODOS.md` exists in this checkout. Future SQLite lineage-budget accounting should be captured in Ardur backlog/operator docs if this task exposes a durable follow-up. + +6. Completeness check: + - Complete Phase 1 behavior means no silent acceptance of unsupported mission-declared lineage budgets. It does not mean implementing every v0.1 spec concept.

Add three new CI jobs: rwt-phase1 (fresh-user CLI smoke), examples-smoke (governance integration tests through demo code paths), latency-bench (informational, continue-on-error). Add 11 organic governance integration tests that exercise GovernanceProxy, session management, tool evaluation, budget enforcement, LangChain governed tools, and demo_scenes helpers through real Ardur code paths without needing LLM providers.

Adds: - Manifest digest comparison (observed vs declared tool_manifest_digest) - Envelope signature validation (strict boolean True required) - Visibility gating (must be "full" for MIC-State+) - Hidden-hop detection via _last_seen_receipts (MIC-Evidence only) - Delegation chain receipt gap detection (MIC-Evidence only) All 29 test_mic_conformance tests now pass (were 25 failing). Adds _last_seen_receipts in-memory tracking populated from _log_receipt.

TLS support via --tls-cert/--tls-key/--no-tls CLI flags with auto-detection - Kill switch with activate/deactivate admin endpoint and Prometheus gauge - Per-IP rate limiting with 429 responses and graceful cleanup - Security headers: X-Content-Type-Options, X-Frame-Options, CSP, Referrer-Policy, Cache-Control, HSTS (when TLS active) - Biscuit passport support in /session/start with SPIFFE peer validation - Prometheus /metrics endpoint with requests_total counter - Sync DECLARED_TELEMETRY_FIELDS with claude_code_telemetry mirror - Restore biscuit_issuer_public_key parameter to __init__ Fixes all 41 macOS HTTP errors (serve_proxy now accepts no_tls parameter). Test suite: 644 passed, 0 failed, 21 skipped.

-0500 Subject: [PATCH 044/124] test(e2e): add comprehensive end-to-end showcase test suite (28 tests, 7 layers) Adds test_e2e_showcase.py with 28 tests covering every Ardur governance capability using real Ollama (no mocks). Includes CI job in tests.yml that runs on workflow_dispatch and pushes to main. Layers: HTTP Security, Session & Passport, Delegation, Receipts, MIC Conformance, Policy Backends, Advanced Features.
