Phase 2: proves ADR-0006/0008 semantics end to end with the fake provider and fake clock (cooldown expiry, backoff growth, inline-alias failover, permanent-error policies, retry budgets, bench-mid-request, exhaustion reporting, custom classifier, chain-of-one parity).

2026-06-10 — Phase 2: health + failover chain, proven
Landed: the full deterministic failover test matrix over the fake
provider + fake clock (no sleeps, no network): single-transient recovery
via same-target retry; repeated transients bench + advance; cooldown expiry
re-admits and success resets; backoff doubling across bench rounds;
mixed chain with an inline-expanded alias element failing over through the
expanded targets; permanent-policy default (fail-fast on auth) and
AdvanceOnPermanent override; TransientRetries disabled/custom; retry
loop stops early when the tracker benches mid-request; exhaustion error
lists skipped-while-benched targets; custom classifier override; chain-of-
one gets identical semantics; HTTP 529 fails over. Implementation needed no
changes — Phase 1's executor held up.
Next: Phase 3 — OpenAI/Anthropic/Ollama/foreman REST clients + media pipeline.
2026-06-10 — Phase 1: foundations, ADRs, skeleton, docs
Landed:
- Module scaffold (Go 1.26),
.gitea/workflows/ci.yaml(foreman-style gates: build, vet, race tests, tidy-diff),.env.example. llm/canonical contract: Message/Part (sealed; text+image), Request/Options, Response/Usage/FinishReason, Stream/StreamEvent, Tool/Toolbox (panic-safe Execute), Capabilities (zero-value semantics), Model/Provider interfaces, APIError + transient/permanent Classify.health/: clock-injected tracker — consecutive-failure threshold, exponential capped cooldown, reset-on-success, thread-safe; full deterministic test suite (fake clock).- Root: Registry (providers/aliases/schemes/health), Parse with the binding grammar (verbatim model ids, inline recursive alias expansion, cycle detection, dedup), LLM_* env-DSN loading (go-llm-parity lazy fallback + eager LoadEnv/New scan), chain executor implementing Model (retry-on-transient, bench-on-repeat, skip-benched, 404-advance, fail-fast-on-auth, joined exhaustion errors). Built-ins register as resolvable stubs until their phases land.
provider/fake/: scriptable provider (per-model outcome queues, request recording, capabilities overrides, streaming) — the hermetic test rig.- ADRs 0001–0008 + index; CLAUDE.md; honest README with pending-marked matrix.
- Tests cover the two required cases: the trailing-
thinkingchain parse andLLM_M1=foreman://token@hostloading (plus DSN table, lazy fallback, cycle detection, chain failover/backoff/exhaustion, toolbox execution, error classification).
Notes: chain executor landed in Phase 1 (design was settled); Phase 2 deepens its test matrix (cooldown re-admission via fake clock, alias-in-chain failover, permanent-policy override) and wires anything the tests flush out.
Next: Phase 2 — exhaustive health/chain test matrix.
