It fills a clamped schema: enums, subsets of operator-configured values, and two narrowly bounded text fields (a ≤120-char muted context block, ≤200-char thread notes).

The decision schema structurally lacks a "don't post" option. +3. **Policy outranks AI.** Existing deterministic policies (`ignore_ai_reviews` bot suppression, dependabot compact format, draft deletion) run before the advisor is consulted. The AI modulates within what policy allows and can never un-suppress or override an operator decision. +4. **Rule-sufficient decisions skip the model.** Anything a regex or a config lookup answers (known bot authors, breaking-change marker detection) is computed deterministically and fed to the model as a signal — never asked of it. + +## Scope and phasing + +**V1 surfaces (this spec, existing events only):** + +| Surface | Trigger | AI decides | +| --- | --- | --- | +| New-PR salience | `opened` / `ready_for_review` | per-channel loudness, mention subset, leading emoji, standard-vs-compact format, breaking-change emphasis, context block, thread note | +| Monorepo semantic routing | same event, multi-candidate mappings | which of the mapping-declared candidate channels to post to, per-channel decisions for each | +| Message update | `approved` / `commented` / `changes_requested` / `merged` / `closed` | which allowlisted emoji to react with (or decorate the close with) | +| Digest intelligence | digest cron | stuck-PR ordering, per-PR highlight, per-PR thread note, parent ping-vs-quiet | + +**Stage 2 (out of this spec; the contract is shaped for it):** CI-failed and PR-updated (push/synchronize) triggers — natural extensions of the `DecideUpdated` surface — once the deterministic CI state machine (engine#31) lands; flaky-vs-real CI classification; a deferred-ping upgrade primitive (post quiet now, ping when CI turns green — the same primitive off-hours batching would use). + +Breaking-change detection needs no new ingestion: `kernel.PR` already carries Title and Body, so the conventional-commits marker (title `!`, breaking-change footer in the body) is a deterministic v1 signal. + +## Architecture + +A new eighth domain, `internal/salience/`, following the standard three-layer layout.

The composition root appends exactly one provider module based on `ai.provider`, and none when `ai.enabled: false` — no gateway constructed, no HTTP client, no AI code path active. (In Go, "not loaded" means not wired/instantiated; the compiled code remains in the binary, which is harmless. Dynamic `.so` loading via Go's `plugin` package was evaluated and rejected: platform-restricted, CGO-dependent — it would break the static alpine build — and requires exact toolchain/dependency lockstep.) + +**External plugin repositories** are a supported future direction, not v1: everything under `internal/` is unimportable cross-repo, so the day external adapters materialize, `ModelGateway` + its DTOs get promoted to a public `pkg/` package — designed deliberately tiny and SDK-free so that promotion is mechanical. For LLM providers specifically, the OpenAI-compatible adapter already acts as an out-of-process plugin system: pointing `base_url` at LiteLLM/Ollama/OpenRouter covers the provider long tail with zero new machinery.

The key never appears in `config.yaml`. +- **Per-tier overrides in `mappings:`** (same inheritance as `reactions`/`reviews`/`digest`): `ai.enabled` tri-state (absent = inherit) to opt a repo/org out, and `ai.instructions`, which concatenates global → org-tier → repo-tier so guidance narrows rather than replaces. Deliberately **not** per-tier: provider, model, key — one provider per deployment, mirroring the `git_provider` stance. Instructions are operator-trusted (whoever writes config.yaml owns the server), so they are prompt input, not an injection surface. +- **Boot validation (fail-fast):** unknown provider; enabled without `model`; gemini without `AI_API_KEY`; `openai_compatible` without `base_url`. Provider *unreachability* is deliberately not a boot check — the runtime fallback owns outages. +- **Deliberately not configurable in v1:** the per-decision timeout (a 2.5 s constant in `salience/domain/constants.go`), any daily request cap (v1 ships uncapped — cost control is per-decision token logging, the decision cache, the circuit breaker, and the provider's own quotas), and per-surface toggles (enabling AI enables all three surfaces; per-tier `ai.enabled` remains the opt-out). Each can be promoted to a config key later without migration. +- **Doctor:** new AI section — config shape, key presence (redacted), endpoint reachability, and a one-token structured-output probe against the configured model (proves key validity and model availability, measures latency). The probe also reports **rate-limit headroom, best-effort**: OpenAI-compatible endpoints that send `x-ratelimit-*` response headers (OpenAI, OpenRouter, LiteLLM setups that forward them) get requests/tokens remaining surfaced as an info-level check; local endpoints without the headers report "no limits exposed". Gemini offers no quota-read API for a bare API key (quota lives in the AI Studio / Cloud console), so the check reports limits as provider-enforced — and if the probe itself gets a 429, doctor surfaces the provider's error detail naming the tripped quota and any retry-after. Remediation text links the provider's quota console. +- **No changes to `config.lock` or the validation domain** — AI settings don't affect mapping-entry hashes and need no per-entry external checks. +- In code, `platform/config`'s file schema gains the `ai` block parsed into a salience-owned config DTO (precedent: `routingdomain.DigestConfig` inside `Config`). + +## Guarding pipeline + +Four pure-Go stages inside `ModelAdvisor`; all caps and patterns are constants; all stages unit-test without a network. + +**1.

Redact secret-shaped strings before anything leaves the process (`ghp_`/`gho_` tokens, `xoxb-`/`xoxp-`, `AKIA…`, PEM headers, JWT-shaped triplets, long high-entropy hex) — PR bodies occasionally contain leaked credentials and must not reach a third-party API. Rule-sufficient cases (known bot authors) never consult the model at all. + +**2. Guard inbound.** All attacker-influenced fields (title, body, login, paths, digest titles) are placed only inside a delimited data envelope; the system prompt declares the envelope data-never-instructions; delimiter collisions in content are neutralized. A heuristic tripwire ("ignore previous instructions"-class patterns) does not refuse the event — it flags `guard_tripped`, routes that one event to the deterministic path, and logs a warning. **The model receives zero tools and one turn.** The app posts to Slack; the model only fills a schema — there is no agentic loop to hijack. + +**3. Structured output.** Gemini `responseSchema` / OpenAI `response_format: json_schema` enforce shape provider-side; the client strict-parses regardless. No lenient repair, no retry — a malformed response is a fallback; systemic failure is the circuit breaker's job. + +**4. Clamp and sanitize.** The table above, applied per field, pure and provider-independent — the only door into consumer code. Text-field sanitizer: mrkdwn-escape; strip Slack mention syntax (`@here`, `@channel`, ``, `<@…>`); strip URLs except the PR's own; enforce length; single-line for context blocks. + +**Net threat model:** a successful injection can at worst pick a wrong-but-valid enum or produce a weird ≤ 200-char sanitized note. It can never mint mentions, channels, or links, never ping anyone not already configured, and never hide a PR. + +## Resilience + +- **Timeout:** per-decision context deadline, a 2.5 s constant in `salience/domain/constants.go` — safely inside GitHub's 10 s webhook window; the digest cron path may use a more generous internal deadline. +- **Circuit breaker:** 5 consecutive gateway failures → open 10 minutes → half-open single probe. Constants in `salience/domain/constants.go`. +- **Cache:** in-memory LRU (512 entries, 24 h TTL) keyed by surface + repo + PR number + content hash — absorbs GitHub redeliveries and duplicate deliveries. Re-spend after a restart is acceptable — decisions are cheap and duplicate deliveries are rare. +- Every skip lands on `DeterministicAdvisor`: zero I/O, always succeeds. + +## Observability + +One structured `ai decision` log line per consultation: surface, provider, model, latency_ms, tokens in/out, cache hit/miss, `fallback_reason` (empty = model decision applied), truncated rationale. This mirrors the existing `ignored webhook event` contract; the operations doc gets a matching reason table. Per-decision token logging is the v1 cost-visibility story. + +## Testing + +- **Regression anchor:** golden tests assert `ai.enabled: false` produces byte-identical Slack payloads to current behavior — the deterministic advisor is provably a pure repackaging; this is what makes the consumer refactor safe. +- **ModelAdvisor** (fake gateway): table-driven clamp tests (out-of-set mentions/channels/emoji, oversize notes, invalid permutations), sanitizer tests (mention-syntax stripping, link stripping, mrkdwn escaping), minimizer goldens (real dependabot body, secret-redaction fixtures), injection-corpus fixtures proving `guard_tripped` routing. +- **ResilientAdvisor:** timeout → fallback; circuit opens after 5 and half-opens; cache hits skip the gateway (fake counts calls). +- **Provider adapters:** `httptest` contract tests — request shape (auth header, model, schema), parse paths, 429/5xx taxonomy, keyless openai_compatible mode. +- **Wiring:** runtime tests assert disabled ⇒ deterministic binding and no provider module; enabled ⇒ resilient + correct provider module; malformed AI config aborts boot. +- No live-API calls in CI. TDD throughout, per repo rules. + +## Documentation plan + +New `docs/ai.md` (what the AI decides, what it can never do, provider setup including an Ollama example, cost expectations, log-line reference). Updates: `configuration.md` (ai block + `AI_API_KEY` row), `mappings.md` (per-tier override), `operations.md` (`ai decision` reason table), `doctor.md` (AI section), `security.md` (AI threat model: what leaves the process, redaction, injection stance), `features.md` (mention). + +## Rollout and implementation phasing + +Ships default-off as a `feat:`. Implementation proceeds in independently-green phases: + +1. Salience domain skeleton + `DeterministicAdvisor` + consumers refactored through decisions, with byte-identical goldens. +2. Config, secrets, boot validation. +3. Guard pipeline + `ResilientAdvisor` (timeout, circuit, budget, cache). +4. Gemini provider module. +5. OpenAI-compatible provider module. +6. Doctor section + documentation. + +## Success criteria + +- AI off ⇒ byte-identical output (goldens prove it). +- AI on with a dead provider ⇒ every delivery still lands via fallback; zero AI-caused webhook failures; added p99 latency ≤ the configured timeout. +- Every model consultation is attributable via one log line with a rationale. +- The injection test corpus can never produce unclamped output. +- Cost is observable: every decision logs its token usage. + +## Out of scope + +PR summaries or any AI-composed message body; AI code review; AI suppressing or hiding a PR; SaaS/multi-tenant concerns (launchpad-be#15 covers those separately); CI-failed and PR-updated surfaces (stage 2, after engine#31); external plugin repositories (future; enabled by promoting the gateway port to `pkg/` when needed). diff --git a/go.mod b/go.mod index 87f5b90..f9d8b7a 100644 --- a/go.mod +++ b/go.mod @@ -1,6 +1,6 @@ module github.com/mptooling/notifycat -go 1.25.11 +go 1.25.12 require ( github.com/glebarez/sqlite v1.11.0 diff --git a/internal/diagnostics/application/doctor.go b/internal/diagnostics/application/doctor.go index 024f53d..e4bc151 100644 --- a/internal/diagnostics/application/doctor.go +++ b/internal/diagnostics/application/doctor.go @@ -10,29 +10,32 @@ import ( validationdomain "github.com/mptooling/notifycat/internal/validation/domain" ) -// Doctor implements diagnosticsdomain.Doctor.
