From 3cac021213c4f308e1c8a526de842c57470420db Mon Sep 17 00:00:00 2001 From: Bernd Worsch Date: Wed, 1 Apr 2026 19:52:20 +0000 Subject: [PATCH] =?UTF-8?q?feat(WP-0010):=20IHF=20Phase=209=20=E2=80=94=20?= =?UTF-8?q?External=20API=20Surface=20and=20Consumer=20SDKs?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Delivers the full Phase 9 external API layer: - Versioned REST API (/api/v2/) with OpenAPI 3.1 spec; enum arrays for widget_type, event_type, annotation category drawn live from registry tables - OAuth 2.0 client credentials flow (/api/v2/token); hub:*:write scopes gated on active HubCapabilityManifest FK - API key management: SHA256-hashed tokens, key_prefix for display, one-time reveal on creation, revocation support - TypeScript and Python consumer SDKs generated from registry tables (/api/v2/sdk/ihf-client.ts, /api/v2/sdk/ihf-client.py) - Webhook delivery: HMAC-SHA256 signing, append-only webhook_deliveries, fire-and-forget dispatch via forkIO, 3-retry logic - Admin API dashboard with 24h stats (request count, error rate, last seen) - Rate limiting (per-minute) and daily quota enforcement via api_request_log - Schema migration: api_consumers, api_keys, webhook_subscriptions (CHECK constraint on 6 framework lifecycle topics), webhook_deliveries (append-only trigger), api_request_log - ARCHITECTURE-LAYERS.md scorecard: 3.34 → 3.41 (approaching Strong) - contracts/functional/interaction-reporting-v1.md extended with Phase 9 endpoint catalogue and 422 validation error format GAAF: no bare TEXT discriminators; webhook event_type uses CHECK constraint over 6 allowed framework lifecycle topic strings (not widget event types).

Capture: + `api_consumer_id`, `endpoint`, `method`, `status_code`, `latency_ms`, + `requested_at`. + +2. `Web/Controller/ApiDashboardController.hs` with `ShowApiDashboardAction`: + - Aggregate query: per-consumer request count (last 24h), error rate + (4xx+5xx / total), last-seen timestamp, top 5 endpoints + - Uses IHP `AutoRefresh` for push updates on new log rows + +3. View (`Web/View/ApiDashboard/Show.hs`): + - Summary table: consumer name, requests (24h), error rate %, last seen, + manifest linked (✓/–) + - Time-series sparkline (optional; use a simple count-per-hour query if + rendering inline) + - Error breakdown panel: group by status code + +4.

Middleware (applied to all `/api/v2/` routes) before action dispatch: + - Count requests in the last 60 seconds from `api_request_log` for the + consumer. If `> rate_limit_per_minute` → HTTP 429 with + `Retry-After: ` header. + - Count requests today (since `quota_resets_at - 1 day`) for the consumer. + If `> quota_per_day` → HTTP 429 with + `X-Quota-Resets-At: ` header. + - Both return JSON `{ "error": "Rate limit exceeded", "code": "rate_limited" }` + or `"code": "quota_exceeded"`. + +2. Quota reset: add a daily job `Web/Job/QuotaResetJob.hs` that runs at + 00:00 UTC and updates `quota_resets_at` to the next midnight for all + consumers. + +**Close-out:** + +3. Update `CLAUDE.md`: + - Change `Active Workplan` section to point to the next workplan (Phase 10: + IHUB-WP-0011 when created) or mark Phase 9 as complete. + - Add IHUB-WP-0010 to the "Completed workplans" list. + +4. Update `SCOPE.md` to reflect Phase 9 completion. + +5. Update `ARCHITECTURE-LAYERS.md`: + - Add `ApiConsumer`, `ApiKey`, `WebhookSubscription`, `WebhookDelivery`, + `ApiRequestLog` to the Extensions layer. + - Update scorecard (Phase 9 adds external API surface — likely improves + Cross-layer and Configuration scores). + - Set next review date. + +6. Update `/contracts/functional/interaction-reporting-v1.md` to reference + the live OpenAPI spec URL (`/api/v2/openapi.json`) and confirm the Phase 9 + endpoint list. + +7.
