From 48fdea025e4c17342e94db6c17316804e38cd8ec Mon Sep 17 00:00:00 2001 From: Manas Srivastava Date: Fri, 5 Jun 2026 02:41:34 +0530 Subject: [PATCH 1/2] =?UTF-8?q?feat(worker):=20flow=5Fsynthetic=20continuo?= =?UTF-8?q?us-monitoring=20runner=20(P0=20matrix=20=E2=86=92=20metrics=20+?= =?UTF-8?q?=20NR=20event=20+=20reap)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The capstone of the observability pillar: a River-scheduled job that runs the P0 user-flow matrix against prod every 5 min and pushes a green/red matrix to NR. Mirrors the auth_probe.go / deploy_probe.go prober pattern (per-flow result enum pass|fail|degraded, audit_log row on fail + slog ERROR NR fallback) and adds the two things the single-flow probers don't need: - the common/analyticsevent backend→NR bridge (RecordFlowTest → InstantFlowTest custom event, cohort="synthetic" so real dashboards exclude it), and - a create→assert→REAP lifecycle (rule-24 cleanup ledger): every resource a flow provisions is deleted via the real DELETE /api/v1/resources/:id path + a synthetic.reaped audit row, with a 30m orphan-sweep backstop. Flows (this PR, all prod-safe / API layer): - healthz (anon) GET /healthz → 200 + commit_id (also the per-tick commitId correlation for every event, rule 14/15) - auth_me (human) GET /auth/me with a minted session JWT → 200 + email - provision_reap(agent) POST /db/new → DELETE resource round-trip Brevo-free auth: the runner mints an HS256 session JWT locally (JWT_SECRET, the same value the api verifies against — like api/e2e makeSessionJWT), and idempotently seeds a deterministic cohort-tagged synthetic team + primary user, elevating its tier via the same UpgradeTeamAllTiers logic the Razorpay webhook uses. The cohort flag means every team-iterating background job (the already-shipped test_cohort.go guards) no-ops for it. Flag-gated OFF (FLOW_SYNTHETIC_ENABLED, default false — the DoD habit): the whole layer is inert in prod until an operator lights it. Per-flow kill list (FLOW_SYNTHETIC_DISABLED) + a Team-tier sub-flag (FLOW_SYNTHETIC_TEAM_ENABLED, off until Team GA). Registered in buildPeriodicJobs with UniqueOpts (replicas:2 safe), RunOnStart=true. Metrics (rule 25 — alert + tile + catalog land in the paired infra PR): instant_flow_test_total{flow,actor,tier,layer,result} instant_flow_test_latency_seconds{flow,actor,tier,layer} instant_flow_synthetic_reaped_total{flow,outcome} (leaked MUST stay 0) Tests: flag-off no-op, full happy-path matrix + reap + event assertions, per-flow fail/degraded/leak paths, kill switch, no-JWT/seed-failure degrade, orphan-sweep backstop, the Prom impl, and a DB-gated *Integration test proving the cohort-team seed + reaper soft-delete against real Postgres. make gate green (build + vet + go test ./... -short -count=1).

Make every changed line covered: - injectable per-flow budget override (SetBudgetOverrideForTest) → drives the degraded-latency branches deterministically (0 budget = always over). - extract flowSyntheticNoRedirect + RunPanickingFlowForTest + ReapNilDBForTest test seams for the default-client CheckRedirect, the recover() boundary (also covers flowActorForFlow's default arm via an unknown flow id), and the db==nil guards in recordReap/emitFlowTestFailed. - tests for bad-base-URL build_request, closed-port http_error, seed sub-errors (begin/user/elevate/commit), reap http_error (conn hijack), audit-insert error (non-fatal), orphan scan/rows/update errors. - remove two genuinely-unreachable defensive branches (reapResource build_request — url.PathEscape sanitises; mintSessionJWT marshal error — a string/int map can't fail to marshal), matching the deploy_probe `_ =` posture. workers.go: Factory's Override path can't error (analyticsnr.New is never nil) → discard the structurally-dead advisory branch. diff-cover: internal/{config,jobs,workers}.go all 100% on the patch (0 missing). make gate green; golangci-lint clean.
