`. `n` from the
+ **same `tierSizing` table** used at `CREATE USER` time (consistency with
+ provision-time; `-1` ⇒ unlimited). Idempotent — re-applying the same `n` is a
+ harmless no-op. Skip cleanly when: backend ≠ k8s, pod not running, resource
+ expired/anonymous.
+
+**WI-2 — upgrade trigger**
+- `api/internal/handlers/billing.go` `handleSubscriptionCharged`: after
+ `ElevateResourceTiersByTeam`, **enqueue** a River job (do not block the webhook).
+- New worker job `RegradeTeamResources(team_id, tier)`: load the team's active
+ Postgres resources, call `RegradeConnectionLimit` per resource. Best-effort —
+ one failure must not block the rest.
+
+**WI-3 — periodic `entitlement_reconciler` job**
+- `worker/internal/jobs/entitlement_reconciler.go`, cadence ~5 min. For each active
+ Postgres resource: entitled `n` = f(`team.plan_tier`); if `≠ applied_conn_limit`
+ → regrade + update the column. Catches drift from missed webhooks, manual
+ `/internal/set-tier`, downgrades, etc.
+
+**WI-4 — schema**
+- Migration `api/internal/db/migrations/NNN_resources_applied_conn_limit.sql`:
+ add `resources.applied_conn_limit int` (nullable; NULL = never re-graded). Lets
+ the reconciler skip no-op work and gives observability. (The broader
+ `applied_sizing jsonb` from §7 lands in Phase 2.)
+
+**WI-5 — observability**
+- Metrics: `entitlement_regrade_total{result}`, `entitlement_drift_detected_total`,
+ regrade latency. One log line per regrade (`resource_id`, old→new). NR tile +
+ alert if drift persists (regrade failing).
+
+**WI-6 — tests**
+- Unit: tier→connLimit mapping; reconciler drift detection — **iterate the live
+ registry, not a hand-typed slice** (reliability rule 18).
+- E2E: provision a hobby Postgres → upgrade team to pro → assert
+ `pg_roles.rolconnlimit` on the customer DB actually changed.
+- Coverage test that fails if a new resource type gains a tier without a regrade path.
+
+### Sequencing
+1. WI-4 migration + WI-1 proto/provisioner RPC (foundation).
+2. WI-2 upgrade trigger (the fix).
+3. WI-3 periodic reconciler (the safety net).
+4. WI-5 / WI-6 alongside.
+
+### Risks & guards
+- DB unreachable (paused/down pod) → skip, retry next sweep; never hard-fail.
+- `tierSizing.connLimit = -1` → `CONNECTION LIMIT -1` (Postgres = unlimited). OK.
+- Backend ≠ k8s (dev `local`/shared) → no per-role cap exists → RPC no-ops.
+- Never regrade `anonymous`/expired resources.
+- Idempotent throughout (River job + `applied_conn_limit` check) — safe to re-run.
+- Webhook stays fast: enqueue only, never block on the provisioner call.
+
+### Deploy (reliability rules 15 & 23)
+proto change ⇒ `buf generate` ⇒ rebuild **provisioner + worker + api** ⇒ deploy
+each ⇒ verify-live. Provisioner/worker rebuilds are manual unless their auto-deploy
+workflows are confirmed green.
+
+### Assumptions to verify before coding
+- The provisioner can map a resource token → its k8s namespace/pod (it provisioned
+ it — `provider_resource_id`/`key_prefix` should suffice).
+- Worker queue is River (`worker/` uses River per repo docs).
+- Provisioner `tierSizing.connLimit` vs `plans.Registry.ConnectionsLimit` may
+ disagree — Phase 1 uses `tierSizing` (provision-time parity); a follow-up should
+ unify them onto `plans.Registry` (reliability rule 22, single source of truth).

+# Runbook — Rotating shared secrets (PROVISIONER_SECRET, AES_KEY, JWT_SECRET, …)
+
+## Why this runbook exists
+
+On 2026-05-13 the platform served 503 on every `POST /db/new` for ~2 hours.
+The platform `/healthz` reported green throughout. Root cause: `PROVISIONER_SECRET`
+in `instant-infra-secrets` had been rotated, but the running provisioner pods
+captured the old value at startup (the gRPC auth interceptor closes over
+`secret` at `grpc.NewServer` time and never re-reads it). The api pod, which
+mounts the secret via `valueFrom`, restarted naturally on a separate deploy
+and picked up the new value. The provisioner did not. Result: api presented
+the new token, provisioner compared it against the old captured token, every
+RPC came back `code = Unauthenticated desc = invalid provisioner token`.
+
+This runbook prevents that incident class.
+
+## When to use
+
+Use whenever you change any of these k8s secret keys:
+
+- `instant-infra-secrets/PROVISIONER_SECRET` → consumed by api + provisioner + worker
+- `instant-infra-secrets/AES_KEY` → consumed by api + provisioner + worker (vault decrypt)
+- `instant-secrets/JWT_SECRET` → consumed by api (and worker for internal HS256)
+- `instant-secrets/RAZORPAY_WEBHOOK_SECRET` → consumed by api
+- `instant-infra-secrets/PROVISIONER_DATABASE_URL` → consumed by provisioner
+- Anything else mounted via `valueFrom.secretKeyRef`
+
+## Procedure
+
+1. **Stage the new value** (do not yet apply):
+
+ ```bash
+ NEW=$(openssl rand -hex 32)
+ echo "NEW_SECRET=$NEW" # capture for re-use, do NOT commit
+ ```
+
+2. **Patch the Secret** in BOTH consuming namespaces if it lives in both
+ (`instant` and `instant-infra` historically duplicate `PROVISIONER_SECRET`):
+
+ ```bash
+ kubectl create secret generic instant-infra-secrets -n instant-infra \
+ --from-literal=PROVISIONER_SECRET="$NEW" \
+ --dry-run=client -o yaml | kubectl apply -f -
+ # (repeat for instant namespace if the secret is mirrored)
+ ```
+
+3. **MANDATORY — restart every Deployment that consumes this secret.**
+ k8s does NOT auto-restart pods on `valueFrom.secretKeyRef` updates.
+
+ ```bash
+ kubectl rollout restart deployment/instant-api -n instant
+ kubectl rollout restart deployment/instant-provisioner -n instant-infra
+ kubectl rollout restart deployment/instant-worker -n instant-infra
+ ```
+
+ Wait for each rollout to converge:
+
+ ```bash
+ kubectl rollout status deployment/instant-api -n instant --timeout=180s
+ kubectl rollout status deployment/instant-provisioner -n instant-infra --timeout=180s
+ kubectl rollout status deployment/instant-worker -n instant-infra --timeout=180s
+ ```
+
+4. **Verify** via the post-deploy smoke script:
+
+ ```bash
+ bash scripts/post-deploy-smoke.sh https://api.instanode.dev
+ ```
+
+ Exit 0 means the api↔provisioner gRPC auth path is healthy. Exit 3 means
+ one of the consumer pods didn't actually restart (or the new secret wasn't
+ propagated to all namespaces). Repeat step 3 for any deployment that lags.
+
+## What NOT to do
+
+- **Don't kubectl patch the Secret in place and assume pods pick it up.**
+ They don't, for `valueFrom` env mounts. (Volume-mounted secrets DO refresh
+ on disk after ~60s but env vars are captured at process start.)
+- **Don't rotate during peak hours unless you've practiced the rollout cadence.**
+ The api and provisioner share the secret — restarting in the wrong order
+ briefly fails-closed (api with new secret, provisioner still with old)
+ until both converge. Typical window: ~30 seconds per service.
+- **Don't skip step 4.** A green `/healthz` after rotation is necessary but
+ not sufficient — only a successful `POST /db/new` proves the auth path.
+
+## Future-proofing (open RFCs)
+
+- Consider rewriting the provisioner's `UnaryAuthInterceptor` to take a
+ `func() string` provider rather than a captured string, with the provider
+ re-reading from a file-mounted secret. This requires switching the env-var
+ mount to a file mount on the provisioner Deployment, but it gives us
+ zero-downtime rotation.
+- Add a Kyverno policy that flags any `kubectl edit secret` not followed
+ within 5 minutes by `kubectl rollout restart` of the consumer Deployments.

+// Package e2e — Track 1: Backup/restore integration tests.
+//
+// What this file is the next layer up from:
+//
+// - infra/scripts/restore-drill.sh — the actual live drill, mutates the
+// prod cluster (creates a throwaway namespace, restores a backup into
+// a sidecar pod, tears down). Already operator-runnable.
+// - infra/newrelic/alerts/backup-stale-36h.json + infra/k8s/
+// prometheus-rules.yaml `instant-backups` group — the alerting layer.
+//
+// What this file ADDS:
+//
+// 1. TestBackupRestore_Postgres_RPOandRTO — invokes the drill against
+// a TEST cluster (KUBECONFIG_TEST_CLUSTER or KUBECONFIG_DRILL),
+// parses stdout for the "RPO" + "RTO" lines, asserts:
+// RTO < 5 minutes (the Pro-tier SLA promise).
+// RPO < 30 hours (one missed night = a known stale-backup alert).
+//
+// 2. TestBackupRestore_Mongo_RPOandRTO — same, RTO < 3 minutes.
+//
+// 3. TestBackupRestore_Cleanup_NoLeakedNamespaces — after the drill,
+// asserts no `restore-drill-*` namespaces survive. A leaked
+// namespace pins a sidecar pod's PVC indefinitely.
+//
+// 4. TestBackupRestore_FailureMode_ScriptExitNonzero — sets an env
+// override that makes the smoke query fail, asserts the script
+// exits non-zero AND the namespace is STILL cleaned up. Tests the
+// defer-cleanup path of the script, which is the failure mode an
+// operator would hit when the backup itself is corrupted.
+//
+// 5. TestBackupRestore_NRAlert_AggregationWindow — parses
+// infra/newrelic/alerts/backup-stale-36h.json, asserts
+// signal.aggregationWindow == 3600 (1h). The drift guard catches a
+// future PR that silently widens the aggregation window past the
+// published 36h/60h thresholds, breaking the alert.
+//
+// 6. TestBackupRestore_PromRule_ThresholdsPresent — parses
+// infra/k8s/prometheus-rules.yaml, asserts the `instant-backups`
+// group has rules for both the 36h AND the 60h thresholds. This is
+// a registry-style test: walk every rule in the group, assert each
+// named threshold (129600s, 216000s) is present in the expr.
+//
+// CLAUDE.md rule 14 (live-URL gate): this file IS NOT the live-URL gate.
+// The live-URL gate for backup/restore is operator-run
+// `bash infra/scripts/restore-drill.sh` against prod, which already
+// happened on 2026-05-20 (see CHAOS-DRILL-2026-05-20.md). This file
+// guards against regression of the test infrastructure itself: a future
+// PR that breaks the alert YAML, the Prom rule expr, the script's
+// cleanup path, or the RPO/RTO observability would be caught here.
+//
+// Why a separate build tag (`integration_backup` rather than `e2e` or
+// `chaos`):
+//
+// - `e2e` tests run against a live api process; these tests run
+// `kubectl` against a cluster.
+// - `chaos` tests are destructive on the worker pod lifecycle; these
+// are not destructive (they create a throwaway namespace).
+// - The dedicated tag lets the operator opt-in explicitly. CI runs
+// this weekly on a TEST cluster (.github/workflows/
+// integration-backup.yml), never on prod CI.
+//
+// REQUIRED ENV:
+//
+// KUBECONFIG_DRILL — kubeconfig pointing at the drill cluster.
+// MUST NOT be prod. The drill script enforces
+// this on its end (refuses to run outside the
+// expected prod-context name), so a misconfig
+// on the test side is caught either way.
+// DRILL_SCRIPT_PATH — defaults to "../../infra/scripts/

+package e2e
+
+// brevo_webhook_integration_test.go — Track 2: full-pipeline integration
+// tests for the Brevo transactional-delivery receiver.
+//
+// What this adds on top of:
+// - api/internal/handlers/brevo_webhook_test.go — sqlmock unit tests
+// (every event type → matching SQL UPDATE, secret-mismatch 401,
+// malformed-400, oversized-400, unknown-messageId-200, registry
+// drift gate).
+// - api/e2e/brevo_webhook_e2e_test.go — single delivered + single
+// hard_bounce round-trip against a live api + live PG.
+//
+// NEW HERE — closes the gaps the brief calls out:
+//
+// 1. TestE2E_BrevoWebhook_AllEventTypes_RoundTrip — registry walk
+// (CLAUDE.md rule 18). For every entry in
+// handlers.BrevoDocumentedEventsForTest() seed one forwarder_sent
+// row, POST the synthetic event, assert classification +
+// delivered_at populated per the per-event contract (only
+// 'delivered' sets delivered_at; everything else is
+// classification-only). Self-cleans via DELETE on t.Cleanup.
+//
+// 2. TestE2E_BrevoWebhook_IdempotentRedelivery — same delivered event
+// POSTed twice; verifies the second is a no-op (classification
+// stays 'delivered', delivered_at unchanged or strictly
+// monotonic). The handler uses GREATEST(delivered_at, NOW()) so a
+// replay can never bump the timestamp backwards.
+//
+// 3. TestE2E_BrevoWebhook_DeliveredThenBounceNoTimeTravel — exercises
+// the "delivered first, then a delayed hard_bounce arrives" path.
+// Asserts the classification can move 'delivered' → 'bounced_hard'
+// (we accept Brevo's latest signal) but delivered_at IS NOT
+// cleared (we keep the receipt-of-delivery timestamp). This
+// verifies the makeClassUpdater path: classification updates,
+// delivered_at untouched.
+//
+// 4. TestE2E_BrevoWebhook_MalformedPayloadReturns400 — full-pipeline
+// check that a malformed JSON body returns 400 (matches the unit
+// test contract end-to-end against the live router).
+//
+// 5. TestE2E_BrevoWebhook_UnhandledEventReturns200Skipped — 'click' /
+// 'open' / 'request' all flow to the receiver and must 200 with
+// skipped:true; verified against the live router (the unit test
+// only verifies the handler).
+//
+// CLEANUP CONTRACT (CLAUDE.md memory: "Verify against live + remote
+// default branch"): every test t.Cleanup()'s the synthetic
+// forwarder_sent row by audit_id. A failure does NOT block cleanup —
+// t.Cleanup runs even on t.Fatal.
+//
+// COVERAGE BLOCK for the registry walk (rule 17):
+// Symptom: a future Brevo event type is added to
+// brevoDocumentedEvents (api/internal/handlers/
+// brevo_webhook.go) but missing a handler — the unit
+// test catches the registry drift, but a per-event
+// full-pipeline regression (e.g. handler exists but
+// doesn't actually persist the right column) is not
+// caught by sqlmock.
+// Enumeration: handlers.BrevoDocumentedEventsForTest() — the same
+// exported function the unit test uses.
+// Sites found: 8 documented events at time of writing
+// (delivered, soft_bounce, hard_bounce, blocked,
+// complaint, deferred, unsubscribed, error).
+// Sites touched: 8 (this test iterates ALL).
+// Coverage test: a 9th event added to brevoDocumentedEvents WITHOUT
+// a matching expectation in this test will still pass
+// on the default contract (any classification != ""),
+// BUT a missing handler branch is caught by the
+// matched:true assertion AND the per-event class

+//
+// - /cache/new: a double-click from the same fingerprint must produce

+// - /db/new: same shape for postgres. Production cost of a duplicate
+// is higher (whole-database create + CREATE USER ROLE), so this is
+// the load-bearing endpoint for the feature.
+//
+// - /billing/checkout: dedup at the API layer is essential because the
+// downstream Razorpay API charges per subscription created. A
+// fingerprint replay catches the double-tap before it ever reaches
+// Razorpay. (Stack with FOLLOWUP-2's per-team SETNX guard for

+// Package e2e — LEASE-RECOVERY CHAOS DRILL (Test 2 of CHAOS-DRILL-2026-05-20)
+//
+// Behind the `chaos` build tag. Pairs with worker/internal/jobs/
+// chaos_lease_recovery.go.
+//
+// ─── WHAT THIS DRILL EXISTS FOR ───────────────────────────────────────────────
+//
+// CLAUDE.md rule 12 — "Shipped ≠ Verified". Task #172 added
+// `JobTimeout: globalJobTimeout` (20 min) to the worker's River client
+// config so a hung job cannot pin a slot forever. River pairs that with a
+// rescuer that re-leases stuck jobs to other workers after
+// `RescueStuckJobsAfter` (default = JobTimeout + 1h ≈ 1h20m). Neither the
+// timeout NOR the rescuer was ever exercised against a real pod-kill in
+// the live cluster.
+//
+// This drill triggers the rescuer for real.
+//
+// ─── HOW IT WORKS ─────────────────────────────────────────────────────────────
+//
+// 1. Insert a synthetic team into the platform DB (no real customer
+// touched; cleanup at the end).
+// 2. Insert ONE row into the `river_job` table with
+// kind='chaos_lease_recovery', payload = {sleep_seconds=180,
+// team_id=, run_id=}, state='available'.
+// 3. Poll the audit_log for the FIRST chaos.lease_recovery.start row
+// (worker pod has begun the sleep). Note the pod_id from
+// metadata.pod.
+// 4. (Operator step) `kubectl delete pod -n instant-infra
+// --grace-period=0 --force` — simulates OOMKill.
+// 5. Poll audit_log for chaos.lease_recovery.end — must appear with
+// metadata.pod != killed_pod (some OTHER worker pod picked up the
+// job after the rescuer re-leased it).
+// 6. Report the wall-clock from FIRST start marker to end marker.
+// That's the lease-recovery RTO. River defaults give a worst case of
+// ~1h20m; the actual observed RTO is the drill's primary finding.
+//
+// ─── WHY NOT WRITE A TEST THAT KILLS THE POD AUTOMATICALLY? ───────────────────
+//
+// The kill is a destructive operator action that absolutely must be done
+// by a human who can verify the namespace + see the sibling replica is
+// healthy. The drill is structured as Go test scaffolding (DB seed +
+// polling + assertions) and explicit kubectl prompts the operator runs by
+// hand. That keeps the chaos test from accidentally double-killing during
+// a hung run.
+//
+// The test supports two modes:
+//
+// CHAOS_LEASE_MODE=interactive (default) — pauses with operator
+// instructions between phases
+// CHAOS_LEASE_MODE=observe — does NOT prompt; just
+// enqueues the job + polls
+// until END marker appears.
+// Useful for replaying a
+// drill that an operator
+// executed separately.
+//
+// ─── PREREQS ──────────────────────────────────────────────────────────────────
+//
+// * The worker image must include chaos_lease_recovery.go (build
+// master after that file landed). The worker_image_includes_chaos
+// precheck asserts this by reading the worker's running pod kind
+// registry — if the kind isn't registered, the test skips with a
+// loud message ("worker image too old to support this drill").
+//
+// ─── HOW TO RUN ───────────────────────────────────────────────────────────────
+//
+// make chaostest-lease-recovery
+//
+// Required env (same as Test 1):
+//
+// E2E_PLATFORM_DB_URL
+//

+//
+// - k8s reschedules the pod (Deployment self-heal).
+// - GET /healthz recovers (the API stays serving throughout, because the
+// surviving replica absorbs traffic — these run 2 replicas).
+// - In-flight requests fired DURING the kill either succeed or fail
+// cleanly (clean HTTP error / 503) — never a silent drop.
+//
+// ─── SAFETY ENVELOPE — WHAT THIS DELIBERATELY DOES NOT DO ─────────────────────
+//
+// - One pod at a time. Full recovery is awaited before the next kill.
+// - Stateless deployments ONLY. instant-data stateful pods (postgres,
+// redis, mongo, nats) are NEVER touched.
+// - Nothing is scaled to zero. No DB failover. No node drain.
+// - The kill is `delete pod`, which a Deployment immediately replaces —
+// identical to a routine rolling restart, safe on prod.
+//
+// Destructive scenarios worth running in a dedicated maintenance window
+// (DB failover, scale-to-zero, node drain) are described as RECOMMENDATIONS

+//go:build loadtest && e2e
+
+// Package e2e — LOAD & CHAOS HARNESS
+//
+// This file is behind the `loadtest` build constraint so it NEVER runs in
+// the normal `go test ./... -short` PR/deploy gate (no tag) nor the standard
+// E2E gate (`-tags e2e` only). It compiles ONLY under `-tags 'e2e loadtest'`
+// — it reuses the e2e helper layer (baseURL, post, uniqueIP, ...) which is
+// itself `//go:build e2e`, so both tags are required. `make loadtest` /
+// `make chaostest` pass both. The deploy gate passes neither, so this never
+// runs in CI.
+//
+// ─── WHAT THIS HARNESS DOES ───────────────────────────────────────────────────
+//
+// 1. Concurrency / load — N goroutines hammering every provisioning
+// endpoint simultaneously. Asserts: no duplicate tokens, no 5xx,
+// reports latency percentiles + throughput.
+// 2. Fingerprint dedup under burst — confirms the 5/day cap holds and
+// the 6th call returns the existing token, under concurrency.
+// 3. Rate-limit under burst — fires past the limit, asserts clean 429s
+// (never 5xx, never silent drops).
+//
+// ─── THE 402 RECYCLE-GATE PROBLEM, AND HOW WE HANDLE IT ───────────────────────
+//
+// Prod anonymous provisioning from a fingerprint that has provisioned before
+// hits the `free_tier_recycle_requires_claim` 402 gate (see
+// internal/handlers/provision_helper.go recycleGate). A naive load test from
+// one machine would just get a wall of 402s.
+//
+// This harness handles it deliberately with TWO load lanes:
+//
+// LANE A — AUTHENTICATED LOAD (the real concurrency/throughput test).
+// When a Bearer session JWT is present, provisioning routes through
+// newCacheAuthenticated/...Authenticated which bypasses the recycle
+// gate entirely (cache.go:99). We claim ONE free-tier team up front,
+// mint a session JWT, and drive all concurrency load through it.
+// Free tier => zero cost, no Razorpay, no card.
+//
+// LANE B — THE 402 GATE ITSELF AS ASSERTED BEHAVIOR.
+// We also load-test the anonymous path and assert the gate responds
+// cleanly under burst: every blocked call must return a well-formed
+// 402 envelope (error code + claim_url), never a 5xx, never a silent
+// drop. The gate is a real prod surface; its behavior under load
+// matters.
+//
+// ─── COST SAFETY ──────────────────────────────────────────────────────────────
+//
+// - Free tier ONLY. No /db/new pro pods, no Razorpay, no deploy (kaniko).
+// - Every provisioned resource is registered in a ledger and torn down:
+// a deferred per-resource delete AND batch sweeps every BatchSweepEvery
+// provisions AND a final full sweep. The harness asserts a zero-leak
+// ledger before it exits.
+//
+// ─── HOW TO RUN ───────────────────────────────────────────────────────────────
+//
+// make loadtest # load lanes A + B
+// make chaostest # safe pod-kill chaos pass
+//
+// Required env:
+//
+// E2E_BASE_URL live API root, e.g. https://api.instanode.dev
+// E2E_JWT_SECRET JWT_SECRET from the k8s secret (Lane A authed path)
+//
+// Optional:
+//
+// LOAD_CONCURRENCY goroutines per wave (default 20)
+// LOAD_TARGET_NS k8s namespace of instant-api (default instant)

+// Package e2e — PROPAGATION CHAOS DRILL (Test 1 of CHAOS-DRILL-2026-05-20)
+//
+// Behind the `chaos` build tag — never runs in any normal gate. Compiles only
+// under `-tags chaos`. The existing `make chaostest` target ALSO runs the
+// `loadtest+e2e` pod-kill harness; the new `make chaostest-propagation`
+// target runs this file in isolation.
+//
+// ─── WHAT THIS DOES ───────────────────────────────────────────────────────────
+//
+// CLAUDE.md rule 12 — "Shipped ≠ Verified". The propagation_runner job was
+// shipped on 2026-05-15 (migration 058 + worker/internal/jobs/
+// propagation_runner.go) with 10-attempt exponential backoff and a
+// `propagation.dead_lettered` terminal audit row at maxAttempts. The retry +
+// dead-letter path was unit-tested with mocked clocks but the FULL live path
+// (api enqueues row → worker picks up under SKIP LOCKED → real backoff timer
+// → real dead-letter audit row → NR alert) was never exercised end-to-end
+// against the running cluster.
+//
+// This test exercises it against the LIVE platform DB + worker.
+//
+// THE THREE ASSERTIONS
+// --------------------
+//
+// A. Pickup — the worker's propagation_runner picks up our synthetic row
+// on the next 30-second tick (`last_attempt_at` is stamped, `attempts`
+// increments).
+//
+// B. Backoff schedule — the row's `next_attempt_at` advances per the
+// declared propagationBackoffSchedule. attempts=1 should add 1m,
+// attempts=2 should add 5m. We do NOT wait through the full 24h
+// cumulative backoff — see "Shortcut" below.
+//
+// C. Dead-letter — when attempts reaches propagationMaxAttempts (10) on a
+// row whose handler keeps failing, the row transitions to
+// failed_at != NULL AND a `propagation.dead_lettered` audit_log row
+// appears with actor='propagation_runner' AND a structured ERROR log
+// line (`jobs.propagation_runner.dead_lettered`) fires.
+//
+// ─── HOW WE FORCE A REAL FAILURE ──────────────────────────────────────────────
+//
+// handleTierElevation iterates the team's `resources` rows and calls
+// provisioner.RegradeResource for each. To force a deterministic error:
+//
+// - Insert ONE synthetic team (plan_tier='pro').
+// - Insert ONE synthetic postgres resource on that team with a bogus
+// token + provider_resource_id (no real DB role exists).
+// - The provisioner's regradePostgres will run ALTER ROLE against a
+// non-existent role → returns an error → handler returns the error.
+//
+// The chaos drill safely uses a totally synthetic team (no real customer
+// touched) and cleans up at the end (DELETE CASCADE removes the team +
+// resource + pending_propagations + audit rows).
+//
+// ─── SHORTCUT: fast-loop dead-letter via attempts seed ────────────────────────
+//
+// The natural backoff schedule sums to ~24h33m before maxAttempts. To
+// dead-letter in a single chaos run we seed `attempts = propagationMaxAttempts
+// - 1 = 9` and force `next_attempt_at = now()` so the very next worker tick
+// dispatches → handler errors → `attempts+1 >= propagationMaxAttempts` →
+// markDeadLettered fires. This exercises the EXACT terminal-transition code
+// path; only the cumulative wall-clock is shortcut.
+//
+// We ALSO insert a separate "natural-backoff" row at attempts=0 to assert
+// the propagationBackoffSchedule[0] = 1 minute step holds for one cycle on a
+// live worker (Phase B of the test).
+//
+// ─── SAFETY ENVELOPE ──────────────────────────────────────────────────────────
+//
+// - Synthetic team / synthetic resource ONLY. No real customer data touched.
+// - Bogus token means the provisioner ALTER ROLE will fail safely (role
+// does not exist → SQL error → returned to caller). No state mutated on
+// any real customer's Postgres role.
+// - Cleanup runs in t.Cleanup() and on test failure: DELETE the team row
+// (CASCADE handles resources + pending_propagations + audit_log).
+//
+// ─── HOW TO RUN ───────────────────────────────────────────────────────────────
+//
+// make chaostest-propagation
+//
+// Required env:
+//

+// integration tests.
+//
+// What this adds on top of:
+// - api/internal/handlers/readyz_test.go (sqlmock + httptest unit
+// tests for the API handler in isolation).
+// - worker + provisioner have analogous unit-level tests in their
+// respective repos.
+//
+// What's MISSING that this file covers: cross-service contract checks.
+// All three services (api, worker, provisioner) expose /readyz on their
+// own port + namespace. The contract — same JSON envelope, same status
+// vocabulary, same secret-leak discipline — has never been verified
+// across the three services in one pass.
+//
+// Tests below:
+//
+// 1. TestE2EReadyz_AllServices_RespondWithCorrectShape — hit api +
+// worker + provisioner /readyz; assert the documented JSON
+// envelope (overall, service, commit_id, checks[].name, status,
+// latency_ms, last_check_at).
+//
+// 2. TestE2EReadyz_BrevoUnreachable_StaysDegraded — verifies brevo
+// probe is NON-critical: when an invalid api-key is configured,
+// the overall status stays at 200 (degraded), NOT 503. Without
+// a way to set BREVO_API_KEY="garbage" on a live deploy, this
+// test is SKIPPED by default; it documents the contract for the
+// operator to run against a staging cluster.
+//
+// 3. TestE2EReadyz_CacheTTL_NoUpstreamSpam — hits /readyz 50× in a
+// tight loop and asserts the response stays consistent (the
+// per-check cache TTL absorbs the load). Indirectly verifies the
+// runner doesn't bypass the cache on every request.
+//
+// 4. TestE2EReadyz_NoSecretsLeaked — scrapes /readyz from every
+// service, regex-greps the body for hex secret patterns (>=20
+// hex chars contiguous), fails if any match. The actual probe
+// logic NEVER serialises a secret value; this test guards
+// against a future "helpful" PR that adds the api-key to the
+// check's metadata.
+//
+// 5. TestE2EReadyz_ResponseTime_UnderSLA — measures wall-clock
+// latency of /readyz hits; asserts P95 under 500ms (the cache
+// amortises real upstream-probe cost so a single hit is
+// effectively free).
+//
+// 6. TestE2EReadyz_RegistryWalk_AllChecksInMatrix — per-service
+// walk over the checks[].name list, asserts every check name is
+// in the published criticality matrix. Catches the "added a new
+// check but forgot to document it" drift.

+// reliability_contract_test.go — Track 5: cross-track contract test.
+//
+// This is the "no orphan kinds" test that runs in the regular gate (no
+// build tag) when TEST_DATABASE_URL is set. It walks the audit_log
+// event-kind registry surfaced in api/internal/models/audit_kinds.go
+// and verifies the THREE downstream consumers all have a matching
+// hook for every kind:
+//
+// 1. EMAIL — kinds that trigger a user-facing email must have a
+// builder in the worker's eventEmailBuilders map. Surfaced here
+// by an opt-in list (auditKindsThatEmail) since the worker
+// package can't be imported from api/e2e.
+//
+// 2. PROPAGATION — kinds that trigger downstream infra propagation
+// (tier elevation, resource regrade, etc.) must have a handler
+// in the worker's propagationHandlers map AND be a valid value
+// in the pending_propagations.kind enum.
+//
+// 3. FORWARDER LEDGER — kinds whose emission writes a
+// forwarder_sent row must have classification populated
+// correctly (NOT NULL after the worker forwarder runs).
+//
+// The test is INTENTIONALLY decoupled from the worker's source — it
+// inspects the api source file `api/internal/models/audit_kinds.go`
+// for the kind constants (a literal text-source walk) and then
+// cross-references against the consumer registries via the
+// LIVE TEST_DATABASE_URL and an OPT-IN consumer-mapping table in
+// THIS file. Drift in either direction is loud:
+//
+// - A new AuditKind* constant added to audit_kinds.go without an
+// entry in auditConsumerSpec MUST be triaged as "what consumes
+// this?" The test fails until it's documented.
+//
+// - An auditConsumerSpec entry referencing a kind that no longer
+// exists in audit_kinds.go fails the test (catches the
+// "deleted the constant but the runbook still names it" drift).
+//
+// CLAUDE.md rule 18: the auditConsumerSpec table is the registry; the
+// AuditKind* constants are the canonical source of truth; this test
+// is the gate. No hand-typed slice on either side that can drift
+// silently — the table iterates THIS test's expectations, the
+// constants iterate the model file.
+//
+// CLAUDE.md rule 17 coverage block per consumer arm — see

+# New Relic dashboards + alerts (as code)
+
+Version-controlled NerdGraph JSON for the instanode.dev observability stack.
+Track 7 of 8 in the 2026-05-12 observability rollout
+(`/Users/manassrivastava/Documents/InstaNode/OBSERVABILITY-PLAN-2026-05-12.md`).
+
+## Layout
+
+```
+infra/newrelic/
+ dashboards/
+ api-overview.json # rpm, error rate, p95/p99, top endpoints, apdex
+ billing-dunning.json # failed-charge → 7-day grace → recovered / terminated funnel
+ provisioning.json # Custom/Provision/{Success,Fail}, anon-tier recycles
+ deploy.json # /deploy/* build duration, success/fail, active deploys
+ worker.json # River throughput, retries, expire-job lag
+ alerts/
+ dunning-recovery-rate-low.json # 7d rolling recovery rate < 30%
+ error-rate-high.json # error rate > 1% over 5m
+ p95-latency-high.json # p95 > 500ms over 5m
+ payment-failure-spike.json # >10 grace_started in 1h
+ worker-stalled.json # no jobs processed in 10m
+ nats-down.json # >=3 NATS error logs in 5m
+ policies/
+ instant-api.json # umbrella policy alerts attach to via policyName
+ tests/
+ bake_test.sh # schema-shape regression tests (run pre-merge)
+```
+
+Each JSON file is a stand-alone dashboard or alert condition payload in the shape
+NR's NerdGraph schema expects. The `accountIds: ["${NEW_RELIC_ACCOUNT_ID}"]`
+substitution token in dashboard queries is rewritten by the apply tooling (see
+below) to the real account ID before the API call. Both `apply.sh` and the
+Terraform path read the same source files — neither needs a special pre-flight
+adapter step.
+
+Alert JSON files include a `policyName` field that links them to the umbrella
+policy declared in `policies/instant-api.json`. There is no `type` discriminator
+on alert JSON — the mutation name (`alertsNrqlConditionStaticCreate`) encodes
+that, and including `"type": "NRQL"` causes NerdGraph to reject the payload.
+
+## Required env
+
+| Var | What | Where it lives |
+|---|---|---|
+| `NEW_RELIC_API_KEY` | User key (`NRAK-…`) with dashboards + alerts write scope | 1Password vault `instanode-prod`, item `New Relic — User API key (terraform)`. Mirror as a GitHub Actions secret `NEW_RELIC_API_KEY` on the `InstaNode-dev/api` repo. |
+| `NEW_RELIC_ACCOUNT_ID` | Numeric account ID | Same 1Password item. The number under "Account ID" in the NR UI top-right. |
+| `NEW_RELIC_REGION` | `US` or `EU` | We're on `US`. |
+
+The license key used by the Go agents at runtime is a separate secret
+(`NEW_RELIC_LICENSE_KEY`) and lives in the k8s `instant-secrets` Secret
+(see `infra/k8s/secrets.yaml`, owned by track 6) — it is **not** used to apply
+dashboards/alerts.
+
+## Apply — option A: terraform-provider-newrelic (recommended)
+
+The provider's `newrelic_one_dashboard_json` and `newrelic_nrql_alert_condition`
+resources accept these payloads almost verbatim. Minimal example:
+
+```hcl
+terraform {
+ required_providers {
+ newrelic = { source = "newrelic/newrelic", version = "~> 3.40" }
+ }
+}
+
+provider "newrelic" {
+ account_id = var.account_id
+ api_key = var.api_key
+ region = "US"
+}
+
+resource "newrelic_one_dashboard_json" "api_overview" {
+ json = replace(
+ file("${path.module}/dashboards/api-overview.json"),
+ "\"${NEW_RELIC_ACCOUNT_ID}\"",
+ tostring(var.account_id),
+ )
+}
+
+resource "newrelic_alert_policy" "instanode" {
+ name = "instanode"
+}
+
+resource "newrelic_nrql_alert_condition" "error_rate_high" {
+ policy_id = newrelic_alert_policy.instanode.id
+ name = "instant-api — error rate > 1% (5m)"
+ type = "static"
+ enabled = true
+
+ nrql {
+ query = "SELECT percentage(count(*), WHERE error IS true) FROM Transaction WHERE appName LIKE 'instant-api%'"
+ }
+
+ critical {
+ operator = "above"
+ threshold = 1.0
+ threshold_duration = 300
+ threshold_occurrences = "all"
+ }
+
+ aggregation_window = 60
+ aggregation_method = "event_flow"
+ aggregation_delay = 120
+}
+```
+
+Repeat the dashboard resource for each `dashboards/*.json` and map each
+`alerts/*.json` to a `newrelic_nrql_alert_condition` block. Field names in
+Terraform are snake_case; the JSON uses NerdGraph camelCase — translation is
+mechanical (`thresholdDuration` → `threshold_duration`, etc.).
+
+`terraform plan && terraform apply` from CI on push to `main` of the
+`InstaNode-dev/infra` repo (proposed home for this Terraform; not yet created).
+
+## Apply — option B: direct NerdGraph via curl
+
+For one-off bootstrap or when Terraform is unavailable.
+
+**Dashboard:**
+
+```bash
+ACCOUNT_ID=1234567
+API_KEY=$NEW_RELIC_API_KEY
+
+# substitute the real account ID into the JSON
+DASHBOARD=$(jq --arg id "$ACCOUNT_ID" \
+ '(.. | objects | select(.accountIds?) | .accountIds) |= [$id|tonumber]' \
+ infra/newrelic/dashboards/api-overview.json)
+
+curl -sS https://api.newrelic.com/graphql \
+ -H "Content-Type: application/json" \
+ -H "API-Key: $API_KEY" \
+ -d "$(jq -n --argjson dash "$DASHBOARD" --argjson acct "$ACCOUNT_ID" '{
+ query: "mutation($acct: Int!, $dash: DashboardInput!) { dashboardCreate(accountId: $acct, dashboard: $dash) { entityResult { guid } errors { description } } }",
+ variables: { acct: $acct, dash: $dash }
+ }')"
+```
+
+**Alert condition:** create a policy once via `alertsPolicyCreate`, then
+`alertsNrqlConditionStaticCreate` per alert JSON. Both mutations take fields
+that mirror the JSON 1:1 (rename `type: "NRQL"` to the GraphQL enum, fold
+`signal.*` into the top-level input).
+
+NR's official "Dashboards API" page covers the `dashboardCreate` /
+`dashboardUpdate` mutations. "NRQL alert conditions" covers the alert
+mutations. Both at `https://docs.newrelic.com/`.
+
+## Rotating `NEW_RELIC_API_KEY`
+
+1. **NR UI** → API keys → create a new User key with the same role
+ (`Admin` or `All product admin`).
+2. **1Password** → update `instanode-prod` vault → `New Relic — User API key
+ (terraform)`. Add the old key value to the "notes" field with a revocation
+ date so the rotation is reversible for 24h.
+3. **GitHub Actions** → `InstaNode-dev/api` repo → Settings → Secrets and
+ variables → update `NEW_RELIC_API_KEY`. (Will be repeated on the
+ `InstaNode-dev/infra` repo once it exists.)
+4. **Run Terraform** with the new key (`terraform apply`) to confirm it works.
+5. **NR UI** → revoke the old key.
+
+The agent license key (`NEW_RELIC_LICENSE_KEY`) is rotated separately via the
+k8s `instant-secrets` Secret and a rolling restart of the three deployments;
+see `infra/k8s/README.md` (owned by track 6) for that procedure.
+
+## NR account
+
+- Org: instanode
+- Region: US
+- Account name: `instanode-prod`
+- App naming convention: `{service}-{env}` — e.g. `instant-api-prod`,
+ `instant-api-staging`, `instant-api-dev`. The dashboard NRQL uses
+ `appName LIKE 'instant-api%'` so a single dashboard covers all envs;
+ per-env dashboards can be cloned with `appName = 'instant-api-prod'` once
+ staging volume is large enough to be worth separating.
+
+## Validation
+
+```bash
+# Every JSON file must parse + the schema-shape bake assertions must hold
+bash infra/newrelic/tests/bake_test.sh
+
+# NRQL queries are not lintable offline — copy a query into the NR UI's
+# "Query your data" tool to sanity-check syntax after any edit.
+```
+
+`bake_test.sh` enforces:
+
+- Every dashboard/alert/policy file parses as JSON.
+- Dashboards use the `"${NEW_RELIC_ACCOUNT_ID}"` substitution token, never
+ the legacy `[0]` placeholder.
+- Alerts have no top-level `"type"` field — NerdGraph rejects it on the
+ `NrqlConditionStaticInput` mutation.
+- Every alert has `policyName: "instant-api alerts"` linking to
+ `policies/instant-api.json`.
+
+## Dependencies
+
+These payloads assume the metrics/log fields wired up by:
+
+- track 3 (api Fiber NR middleware → `Transaction` events with `error`,
+ `duration`, `name`, `httpResponseCode`; `Custom/Provision/Success` +
+ `Custom/Provision/Fail` timeslices)
+- track 4 (worker River middleware → `job.completed` / `job.failed` /
+ `job.retried` log records with `job_kind`, `duration_ms`)
+- track 5 (provisioner gRPC interceptor → gRPC `Transaction` events)
+- track 2 (`common/logctx` enrichment handler → `service`, `commit_id`,
+ `trace_id`, `team_id` on every log line)
+
+If any of those tracks lands with different field names, update the queries
+here in the same PR.

+// shared across every external boundary the api crosses (provisioner gRPC,
+// Razorpay HTTP, DPoP replay Redis, worker→api internal HTTP).
+//
+// Why a hand-rolled breaker (vs sony/gobreaker or hashicorp/go-conntrack):
+//
+// - We want a SINGLE behavior model across api + worker so on-call only
+// learns the state machine once. Vendoring gobreaker would still leave
+// the worker's HTTP wrapper as a custom thing.
+// - The hot path needs to be lock-free: every gRPC call hits Allow() and
+// Record() and a sync.Mutex around state would serialize every customer
+// provision behind a single semaphore on the api process.
+// - We need NR-shaped metrics (counter on opens / attempts / failures,
+// gauge on state) emitted via prometheus/promauto, and that's easier
+// to wire when the breaker owns its own observation calls.
+//
+// State machine:
+//
+// closed → (consecutive failures ≥ threshold) → open
+// open → (cooldown elapsed) → half-open (one trial allowed)
+// half-open → (trial succeeds) → closed
+// half-open → (trial fails) → open (cooldown restarts)
+//
+// All transitions are observable via the `instant_circuit_breaker_state`
+// gauge (0=closed, 1=open, 2=half_open) labelled by `name`, plus counters
+// for opens, attempts, and failures.
+//

+// T12-4 (BugHunt 2026-05-20): key-version-tagged envelopes for AES
+// rotation.
+//
+// PROBLEM. crypto.Encrypt output is `base64(nonce||ct||tag)` with NO
+// key-version prefix. AES_KEY is a single static value loaded from env.
+// Rotating it instantly breaks every previously-encrypted
+// connection_url + vault_secrets.encrypted_value — gcm.Open returns
+// auth-tag failure. There is no dual-key window for a rolling
+// migration, so any rotation is a hard outage.
+//
+// SOLUTION. EncryptVersioned tags the ciphertext with a one-character
+// version marker ("v1.", "v2.", ...) in cleartext BEFORE base64. A
+// Keyring carries {1: oldKey, 2: newKey, ...} plus an Active version.
+// Decrypt walks the version on the envelope and selects the matching
+// key. Envelopes WITHOUT a "vN." prefix continue to decrypt against
+// the legacy single key — that path is what every existing row uses
+// today. A rotation flow is then:
+//
+// 1. Deploy a build with Keyring{1: oldKey, 2: newKey}, Active=1.
+// Reads use v1+legacy. Writes still emit v1 (no behaviour change).
+// 2. Flip Active=2. New writes emit "v2."; reads still see
+// a mix of unversioned-legacy + v1 + v2 envelopes.
+// 3. Background re-encrypt loop walks each table and rewrites
+// legacy/v1 envelopes as v2.
+// 4. After re-encrypt completes, remove v1 from the keyring.
+//
+// CONVENTION 4 of CLAUDE.md (the "fail-open" claim) is factually wrong

+// auth-tag mismatch. We leave that strict behaviour and gain rotation

+-- path sets otherwise.
+-- 2. stacks.parent_stack_id — UUID nullable, self-FK. When the promote

+-- This table is the dunning state machine: one active row per team
+-- between the first failed charge and either (a) a successful recharge
+-- (status = 'recovered') or (b) the 7-day grace period elapsing

+-- (role='owner') DESC, created_at ASC" idiom that today's admin
+-- customer-list and impersonate handlers rely on.
+--
+-- Why this needs to be a column rather than a derived view:
+-- 1. The current idiom returns a different row if two users share the
+-- same created_at (rare but observed in test setups that bulk-INSERT
+-- a team's seed users in a single transaction — they get identical
+-- now() timestamps). With is_primary explicit, the answer is

+-- 2. The unique partial index below enforces "at most one primary per
+-- team" at the database level, so admin tooling (impersonate, notes,
+-- billing-contact emails) can't accidentally surface two primaries
+-- after a future migration mishap.
+-- 3. Auth + invitation flows that mint or transfer ownership now have
+-- a single boolean to flip atomically, rather than re-deriving the
+-- owner from N rows.
+--
+-- Backfill rule: the earliest-created user per team becomes primary.
+-- This matches the existing DISTINCT ON ordering (created_at ASC) and
+-- preserves the legacy behavior for every existing team. Users with a
+-- NULL team_id (orphaned rows from a deleted team) are left non-primary
+-- by design.
+--
+-- NOTE: we deliberately DO NOT prefer role='owner' in the backfill —
+-- the legacy idiom did, but auditing the production data shows that for
+-- every team where there's an owner, that owner IS the earliest user.
+-- Preferring created_at ASC keeps the migration deterministic across

+-- Powers Wave FIX-I: when a paid-tier team calls DELETE on a deploy or
+-- stack, the API does NOT immediately tear down the resource. Instead it
+-- inserts a row here with a hashed confirmation token + 15-min expiry,
+-- emails the link to the team's primary user, and returns 202. The user
+-- (NOT the agent) clicks the link, which routes back through POST
+-- /api/v1//:id/confirm-deletion?token=<![CDATA[. The handler
+-- validates against confirmation_token_hash, flips status='confirmed',
+-- and only then calls the actual deprovision path.
+--
+-- Why a separate table (not a flag on deployments/stacks):
+--
+-- 1. Same shape covers BOTH deploys and stacks (resource_type
+-- discriminator) without forking the model layer.
+-- 2. The confirmation_token_hash is high-churn write-mostly state that

+--
+-- Motivation: agent-driven deploys silently linger forever today. We want the
+-- default to be a 24h auto-expire so an experimental `/deploy/new` from a coding
+-- agent doesn't accidentally hold a slot indefinitely. The agent (and the user
+-- in front of it) gets six reminder emails over the final 12h, plus three
+-- explicit "keep this" routes: a per-deploy POST /deployments/:id/make-permanent,
+-- a custom TTL via POST /deployments/:id/ttl, and a team-wide
+-- default_deployment_ttl_policy toggle via PATCH /api/v1/team/settings.
+--
+-- Safety: this migration is forward-only and idempotent. Existing rows are
+-- NOT auto-expired by this change — see the explicit backfill UPDATE below
+-- that sets ttl_policy='permanent' on every pre-existing deployment so the
+-- 24h default never blows away anyone's running production deploy.

+-- ttl_policy TEXT — 'auto_24h' | 'permanent' | 'custom'.
+-- Distinguishes a deliberate user choice
+-- ('permanent' / 'custom') from the
+-- server-default ('auto_24h'). The
+-- deployment_expirer worker only deletes
+-- rows where ttl_policy != 'permanent' AND

+-- to dedupe duplicate sends across ticks.

+-- Migration: 051_users_email_lower_unique
+--
+-- P7 (bug-hunt 2026-05-17): the /claim account-takeover guard does an
+-- exact-match GetUserByEmail. migration 023 added idx_users_email_lower
+-- but it is a PLAIN index — not UNIQUE — so the database itself never
+-- prevented "Victim@X.com" and "victim@x.com" from both existing as
+-- separate user rows. The handler-layer fix (NormalizeEmail in
+-- GetUserByEmail + CreateUser) closes the application path; this
+-- migration closes the data-integrity path so a future caller bypassing
+-- the model layer still cannot create a case-variant duplicate identity.
+--
+-- DUPLICATE-DATA RISK
+--
+-- CREATE UNIQUE INDEX fails outright if two rows already collide on
+-- lower(email). The platform's CreateUser has always taken its email
+-- from a verified magic-link / OAuth identity (both already lowercased
+-- in handlers/auth.go), and /claim is the only path that wrote an
+-- un-normalised email — and only ever for a brand-new email (the P0-1
+-- guard refuses pre-existing ones). A genuine lower(email) collision is
+-- therefore expected to be empty in prod, but we MUST NOT ship a
+-- migration that can crash-loop the api pod on apply.
+--
+-- This migration is defensive: a PL/pgSQL block first probes for any
+-- lower(email) collision. If one exists it RAISEs a descriptive
+-- EXCEPTION naming the offending address and the required operator
+-- action (dedup the colliding users rows, then re-run) instead of
+-- letting Postgres emit an opaque "could not create unique index"
+-- error. If none exists it creates the unique index. The whole block
+-- is idempotent — re-running after the index exists is a no-op via the
+-- pg_class existence check.
+--
+-- OPERATOR REMEDIATION (only if the RAISE fires):
+-- 1. SELECT lower(email), count(*), array_agg(id)
+-- FROM users GROUP BY lower(email) HAVING count(*) > 1;
+-- 2. For each colliding group, merge the duplicate user rows into the
+-- canonical (oldest created_at) row — re-point team membership and
+-- foreign keys, then DELETE the redundant rows.

+-- subscription activates/charges. The worker's checkout reconciler scans for
+-- rows that are still unresolved after a grace window, sends the existing

+-- Migration: 054_team_deletion_pending — adds the 'deletion_pending'
+-- intermediate status to the team-deletion state machine so a partial
+-- worker-side destruction failure leaves a recoverable, reconciler-visible
+-- marker instead of a half-deleted team.
+--
+-- WHY THIS EXISTS
+-- ---------------
+-- Migration 032 gave teams.status three values: active, deletion_requested,
+-- tombstoned. The worker's team_deletion_executor sweep destroys customer
+-- DBs, k8s namespaces, and S3 backups, then flips the row to 'tombstoned'.
+-- If a step in that destruction pipeline fails mid-way, the row stayed in
+-- 'deletion_requested' — indistinguishable from a team still inside its
+-- 30-day grace window. An operator could not tell "grace clock running" from
+-- "destruction started and crashed", and the API restore endpoint would
+-- happily resurrect a team whose customer DBs were already dropped.
+--
+-- 'deletion_pending' closes that gap. The executor flips
+-- deletion_requested -> deletion_pending the moment it BEGINS destruction
+-- (grace window has elapsed, teardown is now in flight). From that point:
+-- - the restore endpoint refuses (destruction has started, not safe to
+-- resurrect),
+-- - a mid-pipeline failure leaves the row in deletion_pending (NOT
+-- half-tombstoned),
+-- - the worker orphan-sweep reconciler treats deletion_pending +
+-- tombstoned as the two "owning team is gone" states and finishes /
+-- retries the teardown.
+--
+-- The lifecycle is now:
+-- active -> deletion_requested -> deletion_pending -> tombstoned
+-- | |
+-- v v
+-- (restore) (reconciler retries on failure)
+--
+-- WHY THE CHECK IS DROPPED + RE-ADDED
+-- -----------------------------------
+-- Postgres has no "ALTER CONSTRAINT ... ADD VALUE" for a CHECK. The
+-- constraint name was system-generated by migration 032's inline CHECK
+-- (teams_status_check). We drop it IF EXISTS and re-add a named one so this

+-- (migration 030) filters on it, and migration 030's `last_reconciled_at`

+--
+-- models.CreateResource now inserts 'pending' and a new MarkResourceActive

+--
+-- But migration 049's CHECK constraint is:
+-- CHECK (status IN ('active', 'paused', 'suspended', 'expired', 'deleted', 'reaped'))

+-- Migration: 058_pending_propagations
+--

+-- resources.tier elevated via the atomic upgrade tx) but whose corresponding
+-- infrastructure-side regrade (provisioner RegradeResource → ALTER ROLE …
+-- CONNECTION LIMIT, CONFIG SET maxmemory, etc.) is still pending.
+--
+-- Background — the gap this closes
+-- --------------------------------
+-- Today the api's `handleSubscriptionCharged` (billing.go) calls
+-- `UpgradeTeamAllTiersWithSubscription`. That atomic tx flips `teams.plan_tier`
+-- + `resources.tier` and is the user-visible "you are now on Pro" signal. The
+-- ACTUAL backend regrade (provisioner RegradeResource RPC → infra cap change)
+-- is left to the worker's `entitlement_reconciler` polling every ~5 min.
+--
+-- If that reconciler fails repeatedly — provisioner outage, a one-off bad pod,
+-- a Razorpay webhook re-fire racing pod restart — the customer is left with a
+-- "Pro tier on paper" but "hobby-grade infra" (the snapshot's connection cap
+-- never landed on the live ALTER ROLE …). The drift would correct itself on
+-- the next successful sweep, but nothing alerts when consecutive sweeps fail
+-- for the SAME team — the reconciler just logs WARNs.
+--
+-- `pending_propagations` is the durable backstop. The api enqueues a row at
+-- charge-confirm time. The worker's new `propagation_runner` job pulls rows
+-- whose `next_attempt_at <= now()` and dispatches them by `kind` — for
+-- `tier_elevation` that means calling RegradeResource for every active
+-- resource on the team. Success stamps `applied_at`. Per-resource failures
+-- bump `attempts`, persist `last_error`, and reschedule via exponential
+-- backoff. After `maxAttempts` (10) the row is dead-lettered (`failed_at`)
+-- and emits a `propagation.dead_lettered` audit row at CRITICAL severity —
+-- the alert-able signal an operator can key on.
+--
+-- This is intentionally a SEPARATE table from `audit_log`: the audit log is
+-- append-only, so it cannot carry mutable `attempts` / `next_attempt_at` /
+-- `applied_at` state. It is also separate from the River queue (which the
+-- worker uses for its own periodic ticks) — River is the worker's internal
+-- scheduler and does not gate on platform DB rows; we want this gate ON the
+-- platform DB so the api writes it transactionally next to the upgrade.
+--
+-- Schema notes
+-- ------------
+-- id — surrogate PK. The (kind, team_id, target_tier) tuple is
+-- NOT unique: a customer who upgrades hobby → pro and
+-- later pro → growth must enqueue two distinct rows
+-- (each carrying its own target_tier snapshot). The
+-- idempotency contract is per-row, not per-team.
+--
+-- kind — propagation kind discriminator. Today the only kind
+-- is 'tier_elevation', but the column is open so future
+-- kinds (vault re-encryption, custom-domain DNS,
+-- deploy ingress patch …) can use the same machinery
+-- without a fresh migration. A future kind must register
+-- a handler in the worker's `propagation_runner` registry
+-- — see CLAUDE.md rule 18 (registry-iterating tests).
+--
+-- target_tier — NULL for non-tier kinds; for 'tier_elevation' the
+-- tier the api wants the worker to regrade resources
+-- TO. This is a SNAPSHOT at enqueue time — matches the
+-- "resource.tier is the entitlement-of-record"
+-- invariant (CLAUDE.md convention 5).
+--
+-- payload — open JSONB blob for kind-specific extra data. Empty
+-- for tier_elevation today.
+--
+-- attempts — incremented per failed dispatch. Capped at maxAttempts
+-- in the worker (10) — exceeding it transitions the row
+-- to failed_at (dead-lettered).
+--
+-- last_attempt_at — wall-clock of the most recent dispatch (success or
+-- failure). Lets an operator see when the worker last
+-- touched this row.
+--
+-- last_error — truncated error string from the most recent failure.
+-- NULL on a fresh row and after every successful
+-- attempt (we clear it on success so the row's final
+-- state is clean).
+--
+-- next_attempt_at — the earliest wall-clock the worker may pick this row
+-- up again. Defaults to now() so a fresh row is
+-- immediately eligible. After a failure the worker sets
+-- this to now() + exp_backoff(attempts).
+--
+-- applied_at — terminal: the propagation succeeded. The row is left
+-- in place (not deleted) as the success ledger; the
+-- worker's predicate filters on `applied_at IS NULL`.
+--
+-- failed_at — terminal: the propagation dead-lettered after
+-- maxAttempts. Mutually exclusive with applied_at;
+-- paired with a propagation.dead_lettered audit row
+-- and a structured ERROR log line so the NR alert
+-- can key on either signal.
+--
+-- created_at — wall-clock at INSERT. Useful for SLA reports
+-- ("p95 time-to-applied for tier_elevation rows
+-- this week").
+--
+-- Index strategy
+-- --------------
+-- The hot query is the worker's per-tick pick:
+--
+-- SELECT ... FROM pending_propagations

+-- ORDER BY next_attempt_at
+-- FOR UPDATE SKIP LOCKED LIMIT 50

+-- Migration: 060_resources_auth_mode
+--
+-- Add resources.auth_mode column for the NATS per-tenant isolation cutover
+-- (MR-P0-5 — held architecture P0, 2026-05-20). See
+-- NATS-ISOLATION-MIGRATION-2026-05-20.md for the full rationale.
+--
+-- Background:
+-- NATS in `instant-data` runs unauthenticated. Any pod on the cluster can
+-- dial nats://nats.instant-data.svc.cluster.local:4222 and read/write every
+-- other tenant's subjects + JetStream streams. The "subject prefix derived
+-- from token" pattern is naming convention, not isolation.
+--
+-- Cutover plan: switch NATS to operator mode (per-tenant accounts with
+-- signed user JWTs). The handler + provisioner code lands first and
+-- gracefully degrades to the unauthenticated path while operator keys
+-- are generated. Then operator flips nats.yaml + applies nats-operator
+-- Secret; new provisions mint accounts; existing queue rows stay
+-- grandfathered until they recycle.
+--
+-- This migration:
+-- - Adds resources.auth_mode TEXT NOT NULL DEFAULT 'isolated' with a CHECK.
+-- - Backfills every PRE-cutover queue row to auth_mode='legacy_open' so
+-- the api can keep returning the (un-creds) URL for them until they
+-- expire/get-recycled, without re-issuing isolated credentials we have
+-- no way to revoke later.
+-- - Adds resources.queue_account_seed_encrypted TEXT NULL — encrypted at
+-- rest (AES-256-GCM with the same AES_KEY as connection_url), used by
+-- the provisioner teardown path to re-sign the revocation claim after a
+-- restart.
+--
+-- Backfill rule:
+-- For queue resources only — every other resource_type ('postgres',
+-- 'redis', etc.) keeps auth_mode='isolated' (their default), since auth
+-- has worked since day one for those backends. The column is added to ALL
+-- rows so handler code can read it uniformly without per-type branching.

+-- 061_forwarder_sent_delivery.sql — extend the worker-side send ledger
+-- with Brevo transactional-webhook delivery feedback. Closes the
+-- "201 ≠ delivered" gap: Brevo returns 201 the instant it accepts the
+-- POST, but the actual SMTP relay happens async — so the existing
+-- `classification='success'` row reflects only API-acceptance, NOT
+-- delivery. The new columns capture what actually happened downstream.
+--
+-- WHY (2026-05-20 production incident):
+-- Every email since launch was silently rejected at Brevo's relay because
+-- the sender domain wasn't validated. The forwarder logged
+-- classification=success (200/201 from the API), the audit_log advanced
+-- past the row, and zero users heard from us. The ledger lied because
+-- it stamped success on API-acceptance instead of relay-delivery.
+--
+-- This file is the canonical worker-side definition. `api/internal/db/migrations/061_forwarder_sent_delivery.sql`
+-- is a verbatim copy so the api migration runner applies it on a fresh
+-- platform DB. Keep both in sync.
+--
+-- Receiver-side machinery (the actual webhook handler) lives in
+-- `api/internal/handlers/brevo_webhook.go`. Brevo POSTs to
+-- `POST /webhooks/brevo/:secret` for every transactional event
+-- (`delivered`, `soft_bounce`, `hard_bounce`, `blocked`, `complaint`,
+-- `error`, `deferred`, `unsubscribed`). The handler looks up the
+-- matching row by provider_id (Brevo's messageId, persisted by the
+-- worker at send time) and updates classification + delivered_at to
+-- reflect the actual outcome.
+--
+-- Columns:
+-- * delivered_at — first time we saw a terminal positive event
+-- ('delivered') from Brevo's webhook. NULL while we
+-- only have an API-acceptance row. NOT updated for
+-- non-delivery terminals (bounces, complaints) —
+-- those land in classification instead.
+--
+-- Classification value extensions (free-form TEXT column today, so this
+-- migration is comment-only at the DB level — the api handler writes
+-- the new values, the worker keeps writing 'success' on API-acceptance
+-- and gets overwritten when the webhook arrives):
+--
+-- PRE-EXISTING (migration 059):
+-- 'success' — Brevo API returned 2xx (API-acceptance, NOT delivery)
+-- 'permanent_drop' — F4 missing_renderer / provider Permanent
+-- 'transient_retry' — reserved, not used today
+--
+-- ADDED HERE (written by api Brevo webhook handler):
+-- 'delivered' — Brevo's SMTP relay confirmed delivery to the recipient MX
+-- 'bounced_hard' — Brevo's 'hard_bounce' event — permanent address failure
+-- 'bounced_soft' — Brevo's 'soft_bounce' event — transient delivery problem
+-- 'rejected' — Brevo's 'blocked' event — sender / domain blocked at relay
+-- 'complaint' — Brevo's 'complaint' / 'spam' event — recipient marked as spam
+-- 'deferred' — Brevo's 'deferred' event — relay holding the message
+-- 'unsubscribed' — Brevo's 'unsubscribed' event — recipient pressed unsubscribe
+--

+-- introduced. As of this migration the consumers are:
+-- 1. `api/internal/handlers/brevo_webhook.go` — writer (this PR adds it)
+-- 2. `worker/internal/jobs/event_email_forwarder.go` — writer (success/permanent_drop)
+-- 3. `api/internal/handlers/admin_customer_notes.go` — reader (support panel, free-form display)
+-- New values surface in support queries as-is — the column stays TEXT so
+-- a future provider (SES delivery notifications, SendGrid event-webhook)

+-- B18 hardening (Wave 3 consolidated, 2026-05-21): document the
+-- relationship between forwarder_sent.audit_id and audit_log.id, and
+-- add a partial-index that lets the worker reconcile orphaned ledger
+-- rows ("classification stays in 'success' but no matching audit_log
+-- exists") cheaply.
+--
+-- WHY THIS IS A SOFT FK, NOT A STRICT FK
+--
+-- forwarder_sent.audit_id is a TEXT column on purpose. Several legacy
+-- emit sites (worker reminder builders that pre-date the
+-- audit-log-in-Postgres consolidation) pass a synthetic placeholder
+-- value (`reminder-<resource_id>-<stage>`, `provider-<grace_id>`)
+-- instead of a real audit_log UUID. A FOREIGN KEY constraint would
+-- reject those rows; converting every legacy emitter to the real
+-- UUID would require a multi-PR refactor we have NOT scheduled.
+--
+-- Instead this migration:
+-- 1. Adds a COMMENT ON COLUMN documenting that the column is
+-- USUALLY an audit_log.id but MAY be a placeholder, and that the
+-- worker's orphan-reconciler must tolerate both shapes.
+-- 2. Creates a PARTIAL INDEX on the subset of rows whose audit_id is
+-- a valid UUID (matches the canonical 8-4-4-4-12 hex shape via
+-- regex). This is the set the orphan-reconciler scans; the
+-- placeholder rows are excluded so the index stays tight.
+--
+-- The forwarder_sent table itself was added by migration 055 and

+-- and the partial index keeps the join cost bounded by the size of the

+-- they can't have a matching audit_log row).
+--
+-- The regex is intentionally case-insensitive and tolerates the

+-- 064_forwarder_sent_audit_fk.sql — close gap #6 (forwarder_sent.audit_id
+-- has no FK to audit_log(id), so a team-deletion cascade leaves orphan
+-- ledger rows pointing at non-existent audit_log rows).
+--
+-- BACKGROUND
+--
+-- forwarder_sent.audit_id is TEXT PRIMARY KEY (migration 055). It cannot
+-- carry a direct ON DELETE SET NULL FK against audit_log(id) for three
+-- independent reasons:
+--
+-- 1. Type mismatch. audit_log.id is UUID, forwarder_sent.audit_id is
+-- TEXT. A FOREIGN KEY constraint requires matching types.
+-- 2. PK cannot be SET NULL. audit_id is the table's PRIMARY KEY
+-- (NOT NULL by definition). ON DELETE SET NULL would violate the
+-- PK on every audit_log delete.
+-- 3. Legacy placeholders. Several legacy emit sites (resource-reminder
+-- builders, propagation drivers) write synthetic placeholder values
+-- like `reminder-<resource_id>-<stage>` or `provider-<grace_id>`
+-- into audit_id. A strict FK would reject those rows at insert time.
+--
+-- Migration 063 documented this and added a partial regex-shaped index
+-- but no actual constraint, so orphans still accumulate.
+--
+-- STRATEGY
+--
+-- Add a NEW nullable column `audit_log_id UUID REFERENCES audit_log(id)
+-- ON DELETE SET NULL`. This gives us the strict FK relationship gap #6
+-- asks for, WITHOUT breaking legacy emit sites (placeholder rows simply
+-- leave audit_log_id NULL).
+--
+-- * audit_id stays as-is — the PK + idempotency key, never touched.
+-- * audit_log_id is the new strict-FK breadcrumb. When the worker
+-- emits an event whose audit_id IS a real audit_log.id (the modern
+-- path), it should also populate audit_log_id with the same value
+-- cast to UUID. The forwarder write site will be updated in a
+-- follow-up PR to write both columns; this migration is additive
+-- only and does not require any application change to be safe.
+-- * Backfill: any existing forwarder_sent row whose audit_id is a
+-- valid UUID AND exists in audit_log gets audit_log_id populated.
+-- Placeholder rows leave audit_log_id NULL — semantically correct
+-- because they were never tied to an audit_log row in the first
+-- place.
+-- * Orphan cleanup: rows whose audit_id was a real UUID but whose
+-- audit_log row has since been deleted (via team-deletion cascade)
+-- are the orphans gap #6 describes. After this migration runs they
+-- will have audit_log_id = NULL (because the JOIN in step 2 won't
+-- match), which is the same state placeholder rows are in — the
+-- audit_log breadcrumb is gone, but the ledger row's classification
+-- + delivery semantics are preserved (the email-truth-surface
+-- requirement, CLAUDE.md rule 12).
+--
+-- Once application code writes audit_log_id on insert (follow-up PR),

+// admin_customers.go — founder-facing customer-management surface served
+// under /api/v1/admin/*. All four endpoints are gated on RequireAdmin
+// (middleware reads the JWT email against ADMIN_EMAILS, closed by default).
+//
+// Why this exists: the team dashboard shows the *founder's* team — not all
+// teams. To find a paying customer's storage usage, MRR contribution, or
+// deploy count without writing a one-off SQL session, the founder needs a
+// read-and-light-mutation surface they can hit from a browser or curl.
+// HubSpot/Salesforce can't see this data; Postgres can.
+//
+// Aggregation freshness: every read is a live SQL query against the
+// platform DB (no Redis cache). Admin views are low-frequency by definition
+// (founder hits the page a few times a day), so the per-request cost is
+// trivial and "the dashboard might be 30 seconds stale" is the wrong
+// tradeoff here — admin should see ground truth.
+//
+// All four endpoints return JSON; no HTML. The success agent_action for
+// mutating endpoints (tier change, promo issue) follows the U3 contract so
+// an LLM agent calling these on behalf of the founder gets verbatim copy
+// to relay.

+// admin_impersonate.go — POST /api/v1/admin/customers/:team_id/impersonate.
+//
+// Mints a short-lived (10 minute), read-only JWT scoped to the target
+// customer's team so a platform admin can debug the dashboard "as" the
+// customer without touching their data. Every mutating endpoint under
+// /api/v1/* is gated by RequireWritable, which 403s any request whose
+// JWT carries `read_only:true`. The flag is irrevocable for the session
+// lifetime — there is no "downgrade to writable" path within a single
+// token's validity.
+//
+// Audit trail: every issuance writes an audit_log row with
+// kind=admin.impersonation_started. The metadata blob carries the admin
+// email, the target team_id, and the absolute expiry time so a future BI
+// consumer can reconstruct "who viewed which customer, when, for how
+// long" without re-deriving the impersonation token's claims.
+//
+// What the minted token DOES NOT carry:
+//
+// - uid (user_id) of any real user on the target team. We pass a NIL
+// uuid string for the `uid` claim so downstream handlers that read
+// GetUserID() don't accidentally assign a write to a real user's
+// account. The RequireAuth middleware requires a non-empty uid, so
+// we use the team's nominal owner user id (resolved at mint time) —
+// no user-creation, no shadow account. Document-of-record: every
+// write attempt is rejected by RequireWritable before it reaches the
+// handler, so the uid-owning user never sees the impersonation in
+// their own write audit trail.
+//
+// - audience (`aud`). Audience checking is opt-in per claim (see
+// middleware.RequireAuth) — by omitting it we keep the impersonation
+// token compatible with every existing handler without having to
+// thread an env-specific canonical URL through the mint path.
+//
+// - dpop (`cnf.jkt`). Impersonation tokens are bearer-only; the admin
+// is on a trusted device by definition.

+// agent_action.go — single source of truth for every `agent_action` string
+// returned to the calling LLM agent on a 402/403/409/410/4xx wall.
+//
+// ─────────────────────────────────────────────────────────────────────────────
+// THE U3 CONTRACT
+// ─────────────────────────────────────────────────────────────────────────────
+//
+// Every `agent_action` string returned by this service MUST satisfy these four
+// requirements. They are enforced by TestAgentActionContract in
+// agent_action_test.go and re-asserted at the handler level by the touch-points
+// listed below.
+//
+// 1. IMPERATIVE OPENING.
+// Every string MUST begin with "Tell the user" — the LLM agent's job is
+// to re-articulate the sentence to the human in front of it. Starting
+// every string with the same imperative makes the contract trivial for
+// a downstream LLM to recognize as "verbatim copy I should reproduce."
+//
+// 2. SPECIFIC REJECTION REASON.
+// Every string MUST name the concrete reason the request was rejected:
+// the tier ("hobby"), the limit ("5/day"), the policy ("env_policy_denied"),
+// the resource ("staging twin"). Generic phrasing ("their plan does not
+// allow...") is forbidden — the LLM cannot expand "their plan" into
+// something useful without inventing details.
+//
+// 3. EXACT NEXT ACTION.
+// Every string MUST tell the user the precise action that clears the
+// wall: "Upgrade to Pro", "Claim the resource", "Provision a twin",
+// "Contact support". "Try again later" is not a valid action — that's
+// a transient infra failure that should NOT carry an agent_action at all
+// (those omit the field; see codeToAgentAction curation principles).
+//
+// 4. FULL HTTPS URL.
+// Every string MUST contain an absolute `https://instanode.dev/...` URL.
+// Plain "/pricing" or "the pricing page" forces the LLM to guess the
+// hostname. The full URL is reproduced verbatim → guaranteed-correct
+// link in the user's terminal.
+//
+// Plus the soft target:
+//
+// 5. UNDER 280 CHARS (the "tweet ceiling").
+// LLMs reliably reproduce sub-tweet copy verbatim. Longer strings get
+// summarized, paraphrased, or truncated. The test asserts < 280 chars
+// on every constant below.
+//
+// ─────────────────────────────────────────────────────────────────────────────
+// HOW TO USE
+// ─────────────────────────────────────────────────────────────────────────────
+//
+// 1. Static walls: add a new const to this file, give it a clear name
+// (AgentAction<Domain><Reason>), reference it from the handler.
+// 2. Dynamic walls (tier/limit interpolation): add a builder function
+// (newAgentAction<Domain><Reason>(args...)) here. Builders MUST keep
+// the four-contract requirements after interpolation.
+// 3. The codeToAgentAction registry in helpers.go is the fallback path for
+// handlers that pass only an error code — those defaults are also under
+// test.
+//
+// Adding a new agent_action string OUTSIDE this file (inline in a handler) is
+// a contract violation. The audit runs `grep "agent_action" internal/handlers`
+// on every PR — new strings must land in this file or extend codeToAgentAction.

+// are NEVER returned — those are reserved for the operator audit feed
+// at /api/v1/<admin-prefix>/customers and would leak the operator
+// tooling shape.

+// Redaction: actor emails are partially redacted to first-char +
+// domain ("m***@example.com"). This balances compliance traceability

+// auth_logout.go — server-side session invalidation (A03 tractable fix).
+//
+// Problem (A03): POST /auth/logout and POST /auth/refresh were advertised in
+// the ContractsPage and CLAUDE.md but neither route was registered. logout()
+// in src/api/index.ts was entirely client-side (clearToken only). A stolen
+// localStorage JWT remained valid for up to 24h after the user clicked
+// "Log out" because the server had no revocation mechanism.
+//
+// Tractable fix implemented here:
+// POST /auth/logout — extracts the JWT's jti claim, stores it in a
+// Redis set ("session.revoked:<jti>") with TTL = token's remaining
+// lifetime. The RequireAuth middleware checks this set on every
+// authenticated request and rejects revoked JTIs with 401.
+//
+// What this does NOT fix (catalogued per scope decision):
+// - POST /auth/refresh (token rotation) remains unimplemented. The
+// existing 24h single-token model is unchanged. Adding refresh
+// tokens requires a refresh_tokens table, a rotation strategy, and
+// coordinated changes in every SDK and the dashboard's token
+// refresh interceptor — a multi-day effort. The ContractsPage and
+// CLAUDE.md entries for /auth/refresh are corrected in this PR to
+// reflect reality (removed from "LOCKED"; moved to "NEEDS LOCK"
+// with a clear "unimplemented" note).
+// - Active sessions on other devices/tabs are not ejected. The
+// revocation is per-jti (each login produces a distinct jti), so
+// logging out on one device does not invalidate concurrent sessions
+// on other devices. A global "log out everywhere" feature would
+// require a per-team version counter — out of scope.
+// - DPoP-bound tokens: revocation via jti still works for these
+// because RequireAuth's DPoP path also reads the jti after the
+// standard JWT validation. No special casing needed.

+// Contract with the worker (sibling repo, instanode.dev/worker):
+//
+// The API ONLY writes status='pending' rows into resource_backups /
+// resource_restores. The worker polls these tables every 30s, flips

+// Conventions (match the rest of internal/handlers):
+//
+// - All limits come from plans.Registry (BackupRestoreEnabled,
+// ManualBackupsPerDay, BackupRetentionDays) — never hardcoded.
+// - Tier-gate responses return 402 + agent_action so an LLM caller

+// - Best-effort audit emit on every successful POST. Audit failure

+// - Rate limit uses a Redis key shape consistent with the other
+// per-day caps: manual_backup:<team_id>:<YYYY-MM-DD>. Fails OPEN

+//
+// THE FIX: before minting a new subscription the handler now (a) short-circuits
+// when the team already holds the requested tier or higher, and (b) reuses an
+// existing still-payable subscription recorded in pending_checkouts instead of
+// creating a second one.
+//
+// These tests run under `go test ./...` — the deploy.yml CI gate. They are
+// DB-backed, so they skip cleanly locally when TEST_DATABASE_URL is unset
+// (the same billingStateNeedsDB skip pattern the other billing_*_test.go
+// files use) and execute in CI where the test DB exists.
+//
+// WHY THEY FAIL WITHOUT THE FIX: pre-fix CreateCheckoutAPI calls
+// CreateSubscription unconditionally. TestCheckout_F7_SecondCall_ReusesLivePendingSubscription
+// would see createCalls == 2 (the assertion demands 1) and a different
+// subscription_id on the second response.

+// Two fixes are pinned here:

+// 1. subscription.pending — Razorpay fires this when a charge fails / awaits
+// retry; it is the ONLY soft-failure signal the pre-auth path emits. The
+// webhook now sends the payment-failure notification on it.
+//
+// 2. pending_checkouts — every /api/v1/billing/checkout records a row; the
+// activated/charged webhook resolves it. The worker reconciler (separate
+// repo) notifies rows that never resolve. These tests pin the insert and
+// the resolve-on-success half of that contract.

+// client we cannot reach in unit tests. So instead we directly hit

+
+// We don't add the full end-to-end checkout test because the checkout
+// handler calls live Razorpay; mocking the razorpay-go client at this

+// is covered by:
+// - The validate-time tests above (do we recognise the code?).
+// - The webhook test above (does notes.admin_promo_code_id mark used_at?).
+//
+// Coverage gap: if a future refactor accidentally stops stamping the notes
+// at checkout time, the validate-time + webhook tests both still pass; only
+// the production wire would silently drop the redemption. The mitigation is
+// the named constant checkoutNoteAdminPromoCodeID — both call sites read
+// the same constant. A follow-up could add an integration test that swaps

+// brevo_webhook.go — receiver-side machinery that closes the
+// "201 ≠ delivered" gap for Brevo transactional email.
+//
+// WHY THIS EXISTS (2026-05-20 production incident):
+//
+// Brevo's transactional API returns 201 Created the moment it accepts a
+// POST. The actual SMTP-relay delivery (or rejection) happens
+// asynchronously inside Brevo's pipeline — sometimes seconds, sometimes
+// minutes later, sometimes never. The worker's email forwarder stamps
+// forwarder_sent.classification='success' on the 201 and advances the
+// audit_log cursor, treating "API accepted" as "delivered".
+//
+// On 2026-05-20 we discovered every email since launch had been
+// silently rejected at Brevo's relay because the sender domain wasn't
+// validated. The worker logged success-after-success; zero users heard
+// from us. The ledger lied because it confused API-acceptance with
+// delivery.
+//
+// This file is the receiver side: a public endpoint Brevo POSTs to for
+// every transactional event (delivered, soft_bounce, hard_bounce,
+// blocked, complaint, error, deferred, unsubscribed). The handler:
+//
+// 1. Looks up the matching forwarder_sent row by provider_id (Brevo's
+// messageId, persisted by the worker at send time via the worker
+// change in the same PR).
+// 2. Updates classification + delivered_at to reflect the ACTUAL
+// outcome instead of the API-acceptance state.
+//
+// AUTH SHAPE — URL TOKEN, NOT HMAC
+//
+// Brevo's transactional webhooks DON'T carry HMAC signatures by default.
+// The two ways to lock the endpoint down are:
+//
+// (a) Allowlist Brevo's source IP ranges. Fragile — Brevo's IPs change
+// without per-customer notice, and CIDR maintenance becomes an
+// ops burden disproportionate to the value.
+// (b) Put a shared secret in the URL path itself. Brevo configures the
+// webhook URL once in their dashboard; the path segment IS the
+// proof-of-knowledge.
+//
+// We pick (b): the route is `POST /webhooks/brevo/:secret`, verified
+// against BREVO_WEBHOOK_SECRET via subtle.ConstantTimeCompare. A
+// mismatch returns 401 + an opaque error envelope (no leaked secret in
+// logs — only `have_secret` / `have_param` booleans).
+//
+// NOTE — DISTINCT FROM THE EXISTING /api/v1/email/webhook/brevo HMAC PATH:
+// The HMAC-signed endpoint at /api/v1/email/webhook/brevo (see
+// email_webhooks.go) handles BOUNCE-FOR-SUPPRESSION feedback (writes
+// email_events rows the forwarder reads to skip future sends to
+// bouncing inboxes). That endpoint requires Brevo's optional
+// HMAC-signing header which is only emitted by newer integrations and
+// requires the operator to enable signing per-callback in the dashboard.
+//
+// The new endpoint at /webhooks/brevo/:secret handles DELIVERY-LEDGER
+// feedback (updates forwarder_sent.classification + delivered_at).
+// Brevo can be configured to POST every event to BOTH endpoints — the
+// suppression path stays HMAC-protected; the ledger path uses URL-token
+// auth so it works even with HMAC disabled.
+//
+// IDEMPOTENCY
+//
+// Brevo retries on 5xx with exponential backoff. The handler MUST be
+// idempotent: a re-delivery of the same event with the same messageId
+// is expected. Our update is naturally idempotent because:
+// * UPDATE forwarder_sent SET classification = ... WHERE provider_id = $1
+// produces the same row state on every replay.
+// * delivered_at is set to GREATEST(delivered_at, $now) so a later
+// delivered event doesn't overwrite an earlier delivered_at with
+// a later one, and a bounce that arrives after a delivery is a
+// no-op on delivered_at (only classification flips).
+//
+// UNKNOWN MESSAGE ID
+//
+// A Brevo event whose messageId doesn't match any forwarder_sent row
+// returns 200 OK (not 404). Returning 404 makes Brevo retry, which
+// amplifies the orphan-event problem. The handler logs a WARN with the
+// masked recipient + event_type so an operator can investigate, but
+// the response is 200 so Brevo stops retrying. Common causes for
+// orphans (all benign):
+//
+// * Email sent before the worker started persisting the real
+// messageId (legacy rows with provider_id='audit-<uuid>').
+// * Email sent from a different cluster (staging callbacks arriving
+// at prod, or vice versa).
+// * Brevo-internal test sends (their dashboard "Send a test email"
+// button fires webhooks too).
+//
+// PII DISCIPLINE
+//
+// The raw payload is NEVER logged. Recipient addresses are masked via
+// models.MaskEmail before they appear in any slog line. The messageId
+// IS logged because it isn't PII — it's Brevo's internal opaque
+// identifier.

+//
+// 1. TestRazorpayWebhook_EveryEventBranchHasACoverageTest

+// exercises). The 2026-05-20 deauthenticated/updated/refund.processed
+// branches landed without dedicated tests; this gate stops that
+// pattern from re-occurring.
+//
+// 2. TestCodeToAgentAction_NoOrphans
+// The reverse of TestAgentActionContract_RegistryCoverage. The
+// forward check ("expected codes are registered") was already in
+// place. This adds the reverse: every entry in codeToAgentAction
+// must be referenced by a handler — an orphan entry means a
+// handler stopped emitting the code (rename, ripout) but the entry
+// stayed, lying to agents about a wall they will never hit.
+//
+// 3. TestAuditKindConstants_EveryConstantIsEmittedSomewhere
+// Walks every `AuditKind*` constant in
+// internal/models/audit_kinds.go (via a literal text-source scan
+// identical to e2e/reliability_contract_test.go) and asserts each
+// constant identifier appears at least once outside the

+// Iron rule: a request from Team B against a resource or deployment owned
+// by Team A MUST return 404 (not 403). Returning 403 leaks the existence of
+// cross-tenant rows; 404 keeps the id-space fully opaque.
+//
+// The previous 403 "You do not own this resource/deployment" pattern was
+// fixed across 18 sites (see FIX-B brief). This test exercises every one
+// of those sites end-to-end through the fiber app — seeding a resource or
+// deployment under Team A and hitting the endpoint with Team B's JWT.
+//
+// Coverage matrix:
+// resources/:id GET, DELETE
+// resources/:id/rotate-credentials POST
+// resources/:id/credentials GET (already-correct site — guards regression)
+// resources/:id/pause POST
+// resources/:id/resume POST
+// resources/:id/metrics GET
+// resources/:id/family GET

+// deployments/:id DELETE
+// deployments/:id/redeploy POST
+// deployments/:id (access-control) PATCH (private/allowed_ips)
+// deployments/:id/github POST, GET, DELETE

+// (TXT challenge, ingress, cert) is covered by the live-API e2e suite —
+// these tests only need to prove that:

+// offending limit/current numbers in the JSON payload (so an agent
+// can self-remediate).
+// 2. A team under the cap is admitted to the next step in the handler
+// (the body parse) — we assert the count branch did NOT 402 by
+// reading the body-parse failure that follows.
+//
+// We deliberately stop short of mocking the full happy-path INSERT here —
+// that path lives in models/custom_domain.go which has its own coverage,
+// and exercising it would require mirroring the full set of SELECT/INSERT
+// stubs in sqlmock. The 402 / non-402 split is the actual policy

+//
+// The contract surface is identical — request, confirm, cancel, expire —
+// so a single helper avoids the drift that would happen if the deploy
+// flow's "what counts as paid" definition diverged from the stack
+// flow's. Per-resource specifics (tier check, actual deprovision call)
+// land in tiny callbacks passed into requestEmailConfirmedDeletion /
+// resolveEmailConfirmedDeletion.
+//
+// Header bypass: callers that pass `X-Skip-Email-Confirmation: yes`
+// short-circuit the email step. Reserved for agents that have already
+// obtained explicit user consent on their side (the agent's UI, an MCP
+// confirm dialog, etc). The header is logged in audit metadata so a
+// post-hoc review can correlate "the user actually saw a confirm" with
+// the bypass.

+// or ends with any of secretKeySuffixes → mask.
+// 2. Value heuristic — value matches a credential-bearing URL scheme
+// (scheme://...@... pattern) → mask.

+// deploy_teardown_reconciler.go — P3 fix: tear down expired deployments.
+//
+// PROBLEM SHAPE
+//
+// The worker's DeploymentExpirer sweeps deployments past their 24h TTL and
+// flips status='expired'. Its source comment claimed "the api reconciler
+// tears down" the compute — but no such api reconciler existed. The
+// worker's deploy_status_reconcile.go only polls building|deploying|healthy
+// rows and never calls Teardown. Result: every auto-expired deployment left
+// a live k8s namespace / pod / Ingress / cert running and billed forever —
+// the free-tier 24h TTL was a lie at the infra layer.
+//
+// FIX
+//
+// This file adds a background sweep INSIDE the api (the only service that
+// holds a compute.Provider — the worker module is deliberately decoupled
+// from the k8s SDK). Every deployTeardownInterval it:
+//
+// 1. Lists deployments in status='expired' with a non-empty provider_id
+// (GetExpiredDeploymentsAwaitingTeardown).
+// 2. Calls compute.Teardown(provider_id) — the SAME path DELETE /deploy/:id
+// uses (deploy.go doImmediateDelete) — to destroy the namespace / pod /
+// Ingress / cert.
+// 3. On a successful (or already-gone) teardown, flips the row to the
+// terminal 'deleted' status via MarkDeploymentTornDown so it is never
+// reprocessed and stops being counted as a tier slot.
+//
+// Idempotency / no double-teardown: MarkDeploymentTornDown's guarded
+// `WHERE status = 'expired'` means a row a DELETE /deploy/:id already
+// cleaned (status advanced past 'expired') is left alone — and the next
+// sweep's SELECT no longer returns a 'deleted' row, so a row is torn down
+// at most once. compute.Teardown itself is safe on an already-deleted
+// namespace (k8s NotFound is treated as success by the provider).
+//
+// STACKS
+//
+// Expired STACKS do NOT need a counterpart here. Unlike deployments (which
+// the worker leaves in a non-terminal 'expired' status), the worker's
+// ExpireStacksWorker already DELETEs the k8s namespace AND removes the
+// stacks row in one pass — there is no leaked-infra "expired" stack state
+// for an api reconciler to pick up. See worker/internal/jobs/expire_stacks.go.

+// deploy_webhook_notify.go — Optional notify_webhook field on POST /deploy/new.
+//
+// Today a caller has no async signal that a deploy has reached a terminal
+// state (healthy / failed) — they poll GET /deploy/:id. The notify_webhook
+// field lets the caller subscribe instead: when the deploy hits 'healthy'
+// or 'failed' the worker will POST a payload to the supplied URL (with an
+// optional HMAC-SHA256 signature header when notify_webhook_secret is set).
+//
+// This file owns the *write* path: parsing the multipart fields, validating
+// the URL, encrypting the secret. The *dispatch* path (worker scans
+// notify_state='pending' rows and POSTs to the URL) is a follow-up PR that
+// lives in the worker repo — see the PR description for the contract.
+//
+// Validation rules (kept loud and explicit because they are the SSRF gate):
+//
+// 1. Scheme MUST be https. No http://, no file://, no gopher://. An
+// agent supplying http:// for "convenience" gets a 400 with a
+// copy-pastable agent_action sentence pointing at the docs.
+//
+// 2. Hostname MUST resolve and MUST NOT resolve to a private / loopback /
+// link-local / multicast / unspecified / CGNAT range. This is the
+// SSRF safety net: a malicious agent could try
+// https://169.254.169.254 (cloud metadata) or
+// https://10.0.0.5:8080/admin (internal service). Every resolved IP
+// is checked — if ANY resolved IP is in a blocked range we reject the
+// whole URL. We deliberately do NOT try to "warn and proceed" — the
+// worker dispatches with the platform's egress identity and that
+// authority must not point inward.
+//
+// 3. Hostname literal forms are rejected even before DNS:
+// "localhost" (regardless of /etc/hosts), and any IP literal that
+// itself parses into a blocked range. This stops an attacker from
+// passing 127.0.0.1 as a string literal in the URL.
+//
+// The SSRF check is intentionally synchronous in the request path. The
+// 400 is the right place — the worker shouldn't have to redo the check
+// on every retry, and an "accepted, later silently dropped" path is the
+// hardest-to-debug failure mode.

+// delivery feedback (bounces, unsubscribes, spam complaints).
+//
+// Endpoints:
+// POST /api/v1/email/webhook/brevo — Brevo (Sendinblue) callbacks
+// POST /api/v1/email/webhook/ses — Amazon SES via SNS notifications
+//
+// AUTH SHAPE — different per provider, intentionally not factored to a
+// common interface because the three providers below verify auth in
+// genuinely different ways:
+//
+// Brevo: HMAC-SHA256(key=BREVO_WEBHOOK_SECRET, msg=rawBody)
+// delivered hex-encoded in the X-Mailin-Custom header.
+// SES/SNS: signed by AWS, but the cheap-and-shipping verification we
+// do today is the TopicArn match — the message includes
+// "TopicArn":"arn:...", and we reject anything that doesn't
+// match SES_SNS_SUBSCRIPTION_ARN. Full SNS signature
+// verification (download cert from SigningCertURL, RSA-verify)
+// is reserved for a follow-up; the ARN check stops drive-by
+// traffic but does not stop a determined attacker who has
+// the topic ARN.
+// SendGrid: ECDSA verify against a public key. Stub only today — the
+// handler is not wired into the router until the cutover.
+//
+// FAST RETURN — providers retry on slow responses (Brevo at 5s, SES at
+// 30s), so we must:
+// 1. Verify the signature in constant time.
+// 2. Parse just enough of the payload to extract email + event_type.
+// 3. INSERT (ON CONFLICT DO NOTHING — dedupe is at the model layer).
+// 4. Return 200 immediately, even on partial failure (logged-and-swallow
+// for downstream errors). The only 4xx paths are bad signature /
+// bad payload.
+//
+// PII — the raw payload is stored in JSONB for audit, but the user-facing
+// slog lines NEVER include it. Recipients' email addresses are logged at
+// debug-level only; on production we expect log levels to suppress them.

+// Adds "family:<family_root_id>" syntax to POST /deploy/new resource_bindings.
+// At deploy time the resolver walks the resource family (via
+// models.GetResourceFamily) for the supplied root id, picks the member whose
+// env matches the deploy's env, and substitutes that member's decrypted
+// connection_url. One deploy manifest works across all envs.
+//
+// Design choices:
+//
+// • Resolution happens BEFORE the deployments row is persisted. That keeps
+// the handler's 4xx surface (400 bad UUID, 403 cross-team, 404 unknown
+// root, 409 no env-twin) in front of the user, instead of failing silently
+// inside the async runDeploy goroutine. This is the opposite of vault://
+// resolution which intentionally runs late (inside runDeploy) so vault
+// rotations apply on redeploy. Family bindings, by contrast, name a
+// specific physical resource and should fail fast.
+//
+// • Backward compat: a value that is a raw UUID string (no "family:" prefix)
+// is resolved as a direct resource token lookup. This matches the spec
+// test #6 ("raw token binding still works").
+//
+// • A value that is neither a UUID nor "family:<uuid>" is rejected with
+// 400 invalid_binding. We do NOT pass arbitrary literal strings through —
+// if the caller wants to inject a literal env var, they should use the
+// env_vars field (not resource_bindings). Keeping the resource_bindings
+// map type-pure prevents agents from accidentally injecting a literal
+// "family:bogus" into the pod env.
+//
+// • Feature flag: when cfg.FamilyBindingsEnabled is false, the "family:"
+// prefix is NOT recognised. Such values fall into the UUID-parsing path
+// and fail with 400 invalid_binding (deterministic disable — the deploy
+// cannot accidentally proceed with an unresolved family ref).

+// One-call env-twinning for every "parent" resource a team owns in a source
+// env. The agentic-founder use case: setting up a fresh staging environment
+// when there are 8 prod resources turns from 8 sequential per-resource
+// /provision-twin calls into one request.
+//
+// Behaviour summary (see the bulk-twin brief for the full spec):
+//
+// - Selects active resources where env=source_env AND parent_resource_id IS NULL
+// (the "parents" of each family) for the authenticated team.
+// - Optional resource_types filter (default: all twin-supported types — postgres,
+// redis, mongodb; webhook/queue/storage are silently dropped because they
+// don't have per-env infra and would always 400 unsupported_for_twin).
+// - For each parent: skip if a twin in target_env already exists, otherwise
+// provision via the per-type ProvisionForTwinCore method. Skips are NOT
+// errors — they're explicit "already_existed" counts so idempotency is
+// observable in the response.
+// - Concurrency: a small semaphore (bulkTwinSemaphoreSize) caps in-flight
+// provisions. Bound chosen so a customer with 30 resources doesn't wait
+// 30× serial provision time, but the provisioner gRPC pool / customer-DB
+// CREATE DATABASE serialisation aren't hammered. See the discussion in
+// ENG-RFC §5 for why 5 (not 10): each provision is ~2-5s and 5 keeps the
+// p99 fan-out under 6s on a typical 8-resource bundle.
+// - Idempotency: every parent that already has a twin in target_env is
+// counted into skipped_already_existed. Calling the endpoint twice in a
+// row therefore returns twinned=0, skipped=N — designed in mind of the
+// future Idempotency-Key middleware (brief B1): the natural-key dedup
+// here is what an Idempotency-Key replay would shape into anyway.
+// - Tier gate: Pro+ only. Anon/hobby/free returns 402 with agent_action.
+// - Quota gate: per-team quota headroom (default: large no-op) refuses
+// additional twins past the headroom and reports them as failures with
+// code=quota_exceeded. The default impl is permissive; bulkTwinQuotaFunc
+// is injected in tests to exercise the partial-fill path.
+// - Failure isolation: if any individual provision fails the others are
+// NOT rolled back. The customer retries just the failed ones.
+//
+// HTTP shape:
+//
+// POST /api/v1/families/bulk-twin
+// {
+// "source_env": "production",
+// "target_env": "staging",
+// "resource_types": ["postgres", "redis"] // optional, default = all
+// }

+ "description": "Zero-friction developer infrastructure. Provision real databases, caches, and queues with a single HTTP call — no account, no Docker, no setup.\n\n## Idempotency\n\nEvery POST endpoint that creates a resource is idempotent. Two layered protections cover every retry pattern:\n\n1. Explicit Idempotency-Key header (Stripe-shape, 24h TTL). Pass the same opaque key on each retry of a logical operation and the server replays the first response verbatim. Reusing a key with a different body returns 409.\n2. Body-fingerprint fallback (120s TTL). When the header is absent, the server synthesises a key from sha256(scope, route, canonical-body) and dedups identical retries inside a 120s window. Absorbs double-clicks, mobile double-taps, agent retries on transient 5xx, and reverse-proxy retries on network blips. Use the explicit header for true exactly-once across longer windows.\n\nEvery response from a create endpoint carries:\n- X-Idempotency-Source: explicit | fingerprint | miss — which dedup path matched (explicit = caller passed an Idempotency-Key; fingerprint = the body-fingerprint cache replayed; miss = handler ran fresh).\n- X-Idempotent-Replay: true — present only when the response was served from the cache (either path).\n\n## Rate limit (applies to every route)\n\nA global per-IP rate limit (100 req/min) is applied to EVERY documented endpoint by the router middleware. Exceeding it returns 429 with the standard ErrorResponse envelope (error=rate_limited), a Retry-After HTTP header, and retry_after_seconds in the JSON body. The per-route response maps below may omit 429 for brevity; the canonical 429 shape is documented under components.responses.TooManyRequests and applies to every path. T19 P1-1 (BugHunt 2026-05-20).\n\n## Payload size (applies to every route)\n\nFiber's global BodyLimit is set to 50 MiB — only /deploy/new and /stacks/new (multipart tarballs) and /webhooks/github/* (push payloads) approach that cap; JSON endpoints are bounded to sub-KB bodies by the per-handler shape. Oversized requests return 413 payload_too_large with the standard JSON ErrorResponse envelope (NOT the upstream nginx HTML 502 the older shape returned — T19 P1-2). The canonical 413 shape is documented under components.responses.PayloadTooLarge.\n\n## Security headers (applies to every response)\n\nEvery response from EVERY route — including liveness/readiness probes, OpenAPI document fetch, 4xx error envelopes, 5xx error envelopes, and 404/405 Fiber-default responses — carries the following defense-in-depth response headers, set by the SecurityHeaders middleware ahead of RequestID in the router middleware chain (task #311 wave-3 chaos-verify redo):\n\n- Strict-Transport-Security: max-age=63072000; includeSubDomains — production only (omitted on ENVIRONMENT=development so local http://localhost:8080 doesn't poison the host's HSTS cache). 2-year max-age, includeSubDomains for *.api.instanode.dev.\n- X-Content-Type-Options: nosniff — disables MIME sniffing.\n- X-Frame-Options: SAMEORIGIN — clickjacking defense.\n- Referrer-Policy: strict-origin-when-cross-origin — prevents URL-token leakage across origin downgrades.\n- Permissions-Policy: geolocation=(), microphone=(), camera=(), payment=() — denies powerful browser APIs.\n- Cross-Origin-Resource-Policy: same-origin — blocks no-cors cross-origin fetches.\n\nThese headers are not enumerated in each per-route responses block to keep the spec readable; they apply globally. Coverage test: TestSecurityHeaders_AllEndpoints_AllHeaders_Prod (internal/handlers/security_headers_test.go) iterates 5 representative endpoints (healthz, readyz, openapi.json, db/new, claim) and asserts all 6 headers land on every response."

+// Coverage matches the prompt's 9-case spec:
+//
+// 1. Promote with to="development" → executes immediately (regression test).
+// 2. Promote with to="staging" → 202 + status: pending_approval.
+// 3. GET /approve/<valid token> → status flips to approved, redirect.
+// 4. GET /approve/<expired token> → HTML "link expired"; row flips to expired.
+// 5. GET /approve/<used token> → HTML "already used".
+// 6. Two separate promotes for same team+env → each creates its own row.
+// 7. Pending row writes audit_log of kind promote.approval_requested.
+// 8. Admin POST .../reject → status=rejected.
+// 9. Public GET /approve/:token has no auth requirement.
+//
+// We DON'T spin up a real Brevo client — the worker-side email forwarder
+// reads audit_log rows, so verifying the audit row exists with the right
+// metadata is sufficient at this layer.

+// provision_atomicity_coverage_test.go — MR-P0-3 cross-handler coverage guard
+// (BugBash 2026-05-20).
+//
+// CLAUDE.md rule 18: when the bug class is "all members of a registry should
+// X", the regression test iterates the live registry (here: every .go file in
+// internal/handlers/ that calls models.CreateResource), not a hand-typed
+// slice. This test scans the handlers directory and asserts that every
+// production-code `models.CreateResource(` call site lives in a file that
+// also contains a `finalizeProvision(` call. The orphan-generator bug fixed
+// by MR-P0-3 was exactly this: a handler that inserted a `resources` row,
+// did the backend gRPC, and persisted the connection URL inline with `// fail
+// open` comments — a logged error and a 201 carrying credentials for a row
+// the platform could not address. Catching a new handler that re-introduces
+// that shape at test time (not in prod) is the whole point.
+//
+// The test is intentionally STATIC (string scan over source files), not a
+// reflection-based registry walk: there is no in-memory "provisioning
+// handler" registry the platform exposes today, so a string scan over the
+// canonical authorial source is the cheapest way to enforce the invariant.
+// Per CLAUDE.md convention, this is a "registry-iterating" test even though
+// the registry happens to be the source tree itself: it discovers call sites
+// dynamically rather than encoding them in a hand-typed list that would
+// itself drift.

+// provision_cap_concurrency_test.go — regression coverage for load-test
+// finding F2 (LOAD-CHAOS-REPORT-2026-05-19.md): the per-fingerprint daily
+// anonymous provisioning cap was NOT concurrency-safe. A 30-way simultaneous
+// burst from one fingerprint minted 22–29 tokens instead of capping at 5.
+//
+// THE BUG (TOCTOU): each anonymous provisioning handler did
+//
+// limitExceeded := checkProvisionLimit(fp) // atomic INCR — fine
+// if limitExceeded {
+// existing := GetActiveResourceByFingerprintType(...) // misses
+// if existing-also-misses-cross-service { ... } // misses
+// // <-- FELL THROUGH HERE to CreateResource
+// }
+// CreateResource(...) // every burst caller minted a fresh token
+//
+// During a *simultaneous* burst the ≤5 winning provisions have claimed
+// their atomic-INCR slots but have NOT yet committed a `resources` row, so
+// both dedup lookups return ErrResourceNotFound — and control fell through
+// to CreateResource. All 30 callers minted.
+//
+// THE FIX: checkProvisionLimit's atomic INCR is the gate (its return value
+// IS the caller's claimed slot); the over-cap branch now calls
+// denyProvisionOverCap on the no-existing-resource path instead of falling
+// through — see provision_helper.go.
+//
+// These tests model the exact handler decision flow against the real,
+// fixed helper methods:
+// - TestProvisionCap_ConcurrentBurst_CapsAt5 reproduces F2: 30 goroutines,
+// one fingerprint, asserts ≤5 mints. Fails on the pre-fix fall-through.
+// - TestProvisionCap_Sequential_FiveThenExisting confirms the documented

+//
+// The "wedge" of instanode is: an agent's very first POST /db/new (or any
+// /{service}/new) succeeds with zero auth and returns real credentials in
+// seconds. We MUST preserve that. The abuse surface this gate closes is the
+// *second* POST from the same fingerprint after the previous free-tier
+// resource expired — without this gate, that path returns a fresh 24h
+// anonymous resource forever, indefinitely. With this gate, the second
+// (recycle) POST is required to claim with email first; the user then falls
+// into the existing `free` tier in plans.yaml.
+//
+// Mechanics:
+// - When an anonymous provision succeeds we SET recycle_seen:<fp> with a
+// 30-day TTL. (Set-after-success preserves the wedge — the first
+// anonymous POST has no key, so it can never be gated.)
+// - On every subsequent anonymous POST we read recycle_seen:<fp>. If it
+// exists AND no active anonymous resource is present for the
+// fingerprint, we return 402 free_tier_recycle_requires_claim with a
+// claim URL. The customer claims with email and gets a JWT; the JWT
+// bypasses the gate entirely (auth path skips this check).
+// - 30 days is intentional: long enough that a recycler coming back
+// "next week" is still gated, short enough that an accidental
+// fingerprint hit (e.g. someone moved offices) decays on its own.
+//
+// Note: the spec lists worker/internal/jobs/expire.go as the trigger, but

+// WHY THIS EXISTS (load-test finding F2 — TOCTOU fix 2026-05-19):
+// checkProvisionLimit's atomic INCR correctly hands every burst caller a
+// distinct slot number, so callers 6..N all see limitExceeded == true.
+// The over-cap branch in each handler then tries to look up an existing
+// anonymous resource to return instead of provisioning fresh. But during a
+// *simultaneous* burst the ≤5 winning callers have not yet committed their
+// `resources` rows — so GetActiveResourceByFingerprintType AND the
+// cross-service GetActiveResourceByFingerprint both return ErrResourceNotFound.
+// Before this fix, when both lookups missed, control FELL THROUGH the
+// limitExceeded block to CreateResource — and every one of the 30 burst
+// callers minted a fresh token, blowing the cap (observed: 22–29 tokens
+// instead of 5).
+//
+// The fix closes the fall-through: an over-cap caller that finds no
+// existing resource is genuinely over the cap (its slot number proved it)
+// — the absence of a committed row only means the winners are still
+// in-flight. Such a caller MUST be rejected with 429, never allowed to
+// provision fresh. Handlers call this on the no-existing-resource path
+// instead of falling through.
+//
+// The atomic INCR (the slot claim) plus this hard deny (no fall-through)
+// together make the cap race-safe: at most `cap` callers ever reach
+// CreateResource; callers 6..N either dedup onto a committed winner or get

+// recycle_gate_test.go — Option B "email gate at recycle" tests
+// (FREE-TIER-RECYCLE-2026-05-12.md). These tests guard the wedge plus the
+// gate itself. Order of importance:
+//
+// 1. WEDGE: first anonymous touch on a fingerprint with NO recycle_seen
+// marker MUST pass the gate (return false, no 402). If this regresses
+// the agent's magic-first-touch is broken — that's the entire product.
+// 2. GATE FIRES: second anonymous touch on the same fingerprint AFTER the
+// prior resource ages out → 402 free_tier_recycle_requires_claim with
+// agent_action + claim_url.
+// 3. DEDUP STILL WINS: marker present BUT an active row still exists →
+// gate does NOT fire; the existing daily-cap / dedup branch handles it.
+// 4. EMPTY FINGERPRINT: no fingerprint header → gate doesn't fire (no key
+// to read).
+// 5. FAIL-OPEN: Redis or DB error during the gate check → gate returns
+// false (fails open) so the wedge is never collateral damage.

+// security_headers_test.go — task #311 wave-3 chaos-verify redo.
+//
+// Coverage assertion: every response from the api, including 4xx/5xx
+// envelopes, carries the spec-mandated defense-in-depth headers. This
+// test is the regression gate against the failure mode that triggered
+// this redo — the original task #311 was marked "completed" but the
+// headers were never actually wired into router.go. A repo-wide grep
+// for "Permissions-Policy" returned zero hits on master at the time of
+// the redo brief.
+//
+// The test hits 5 representative endpoints (matching the task spec):
+//
+// 1. GET /healthz — shallow-liveness, 200 happy path
+// 2. GET /readyz — deep-readiness, 200 happy path
+// 3. GET /openapi.json — static JSON, 200 happy path
+// 4. POST /db/new — provisioning route, 401 unauth-rejection envelope
+// 5. POST /claim — claim route, 400 invalid-payload envelope
+//
+// The 4xx-envelope cases are the load-bearing ones — they confirm the
+// headers land on error responses too, because SecurityHeaders runs
+// BEFORE RequestID and before any handler logic that might short-circuit
+// the request via c.Status(...).JSON(...).
+//
+// Two HSTS modes are exercised:
+//
+// - envIsProd=true: HSTS header MUST be present on every response.
+// - envIsProd=false: HSTS header MUST NOT be present on any response
+// (so a developer running `make run` against http://localhost:8080
+// never poisons the host's HSTS cache).
+//
+// Implementation note: we mount the SecurityHeaders middleware on a
+// fresh fiber.App and register stub handlers that mimic each real
+// endpoint's response shape. We can't bring up the full router here
+// (the cfg/db/grpc wiring is heavy), but mounting the same middleware
+// in isolation proves the contract — and a separate router-level guard
+// test in internal/router/ would be the right place to assert wiring
+// order; this file owns the per-endpoint contract.

+// after the client went away. streamLogsSSE captures every write/flush
+// error and breaks the loop on the first one.
+//
+// FIX-2 — context lifetime. The log stream must be opened with a context
+// derived from context.Background(), NOT the fiber request context: the
+// SetBodyStreamWriter callback runs AFTER the handler returns, by which
+// point fasthttp may have recycled/cancelled c.Context(). The caller passes

+// 3. Every service on the source stack must have an image_ref recorded by an
+// earlier successful deploy (migration 017_stack_image_ref.sql). Stacks
+// created before this migration return 412 with an agent_action telling
+// the caller to redeploy the source first. This is a hard fail rather
+// than a silent no-op so the compute-hook gap can never re-emerge.
+// 4. If a sibling stack already exists with target env: copy the source's
+// image_refs onto the target's existing service rows, flip status to
+// "building", and trigger a pull-and-deploy goroutine. Otherwise create
+// a new stack row + service rows with the source's image_refs and run
+// the same goroutine. Vault refs always resolve against the target env.
+// 5. The new (or updated) stack inherits the source's tier and is created in
+// status="building" so callers can poll with GET /stacks/:slug.
+//
+// What changed (vs. the pre-017 implementation): this endpoint used to be a
+// pure DB-row write — a CREATE stack/services with no compute work behind
+// it. The row would sit at status="building" forever because nothing ever
+// flipped it. With per-service image_ref persistence we can finally hand
+// off to runStackPromoteDeploy and have the cached image rolled out under
+// the target's vault namespace.

+// 1. Tier gate: hobby team must receive 402 with agent_action.
+// 2. Tier gate: pro team gets 200 + family payload.
+// 3. Single-env family: only one stack exists → family has one row, is_root=true.
+// 4. Multi-env family: production root + staging child + dev child render in
+// a sensible order (root first, then siblings by created_at).
+// 5. Cross-team isolation: team B cannot read team A's family (404).
+// 6. Anonymous / unauthenticated: 401 (RequireAuth middleware).
+// 7. Cache-Control: short max-age header set so the dashboard can navigate
+// between envs without hammering the API while still refreshing across
+// promote/redeploy boundaries.
+// 8. Unknown slug: 404 (not 500).

+// (in practice impossible, but defensive) still produces a 200 with the

+// team_deletion_test.go — coverage for DELETE /api/v1/team +
+// POST /api/v1/team/restore. Mirrors the resource_pause_test.go style:
+// each test stands up its own DB + Redis + Fiber app, builds a team +
+// user (with explicit role='owner' so RequireRole passes) + JWT,
+// fires the request, asserts the response shape AND the row's status /
+// deletion_requested_at columns.
+//
+// Scenarios covered:
+// 1. Owner with matching slug → 202 + status=deletion_requested.
+// 2. Member (not owner) → 403.
+// 3. Owner with WRONG slug → 409 slug_mismatch, row unchanged.
+// 4. Owner: paused resources side-effect.
+// 5. Restore inside grace → 200, row back to active.
+// 6. Restore after grace expired → 410.
+// 7. Audit emit shape (kind + metadata keys).
+// 8. Razorpay cancel FAILURE — handler ABORTS with 502, team left fully
+// active, a team.deletion_failed audit row records the aborted
+// attempt. "Stop the money" runs first and is a hard gate (atomic-
+// deletion hardening, 2026-05-19).
+// 9. Razorpay-abort idempotency — re-running DELETE after an aborted
+// attempt behaves identically (502, still active).

+// Why the dispatch lives in twin.go (not inline on each handler):
+// - The three "real" provisionable types share the same skeleton:
+// CreateResource → provisionX → encrypt+persist URL → audit log.
+// The variation is only the low-level `provisionX` call.

+// stay in one place.
+// - The three existing handlers expose `ProvisionForTwin(ctx, resource)`
+// entry points so this file never reaches into provider internals.
+//
+// Out of scope (return 400 unsupported_for_twin):
+// - webhook (just a stored token; no per-env infra to provision)
+// - queue (NATS subject is logical; no env-twin semantics)

+// with TestWave3P2_ so a future bug-hunt can `go test -run Wave3P2_`
+// to re-exercise the lot.
+//
+// Findings covered (per the brief):
+// - T13 P2-T13-05 — global BodyLimit
+// - T13 P2-T13-04 — env-var key validation
+// - T19 P1-3 — invalid_body carries agent_action
+// - T19 P1-5 — StorageProvisionResponse documents `note`
+// - T19 P1-6 — WebhookProvisionResponse echoes `name`
+// - T19 P1-1/P1-2 — openapi documents global 429 + 413 envelopes
+// - T7 P3-F — Razorpay signature whitespace rejected
+// - T10 P2-1 — JWT alg-pin (HS384/HS512 rejected on session path)
+// - T10 P2-4 — /claim sends a verification email on success
+// - T12-4 — AES key-version envelope (Keyring round-trip)
+// - T4 P2-4 — UpgradeTeamAllTiersWithSubscription atomicity
+// - T1 P1-5 — decryptConnectionURL fail-closed
+//
+// Tests that need only the standard library or unit-level inputs run
+// without a DB / Redis. Tests that touch the live HTTP surface use the
+// existing testhelpers.NewTestAppWithServices helper.

+// /webhook/new, /deploy/new) PLUS a body-fingerprint fallback that protects
+// every create endpoint against accidental double-creation even when the
+// caller didn't opt in via the header.
+//
+// Rationale: autonomous AI agents (Claude Code, Cursor, MCP) retry on
+// transient errors. Browsers double-tap on flaky mobile networks. Forms
+// resubmit on the back button. Without idempotency, each retry creates a
+// duplicate resource — burning quota and creating cleanup work. The header
+// is opaque and client-supplied (agents generate a UUID per logical
+// attempt). When present, the first response is cached for 24h and
+// replayed verbatim on any subsequent call carrying the same key.
+//
+// Fingerprint-fallback contract (2026-05-14, this file): when the header
+// is ABSENT, the middleware synthesises a fallback key from
+// sha256(scope || "|" || route_pattern || "|" || canonical_body) and
+// caches the response for 120s. Long enough to absorb double-clicks and
+// fast retry storms; short enough that an honest second creation 5
+// minutes later doesn't accidentally replay. Callers who want exactly-
+// once across longer windows must pass an explicit Idempotency-Key.
+// The response carries X-Idempotency-Source: explicit|fingerprint|miss
+// so debuggers can see which path matched.
+//
+// Middleware ordering (see internal/router/router.go for the per-route
+// wiring): RateLimit runs at app.Use scope (global, before OptionalAuth),
+// so by the time this middleware runs the per-fingerprint daily counter
+// has already incremented. THIS IS DELIBERATE: a malicious agent must NOT
+// be able to bypass rate limiting via Idempotency-Key reuse, so replays
+// still consume rate budget. The original-call cost is borne by the
+// counter on the FIRST request; replays add an extra increment, which is
+// the conservative choice — the customer paid for the first call (in
+// quota terms) but a key-reuse attacker doesn't get free attempts.
+// Quota-walls inside handlers (CheckAndIncrementToken) similarly continue
+// to fire on replay paths, but the replay short-circuits BEFORE the
+// handler so the quota counter is unaffected — the cached response simply
+// goes out the wire. Net effect: rate-limit budget = abuse-protected;
+// quota budget = customer-friendly (no double-charge for retries).
+//
+// Cache key shape: idem:<scope>:<endpoint>:<sha256(key)> where <scope> is
+// team_id when the caller is authenticated, otherwise fingerprint. This
+// gives per-tenant key spaces; one team's key can't collide with another's.
+//
+// Cache value shape: JSON-serialised idemEntry (status code + body bytes
+// + body-content-hash + content-type). Stored with 24h TTL.
+//
+// Replay contract: a hit replays the cached status + body + Content-Type
+// verbatim and sets X-Idempotent-Replay: true. If the cached body-hash
+// does NOT match the current request body, return 409 conflict (the agent
+// reused a key for a different request — almost certainly a bug).
+//
+// Precedence vs handler-internal fingerprint dedup (W11, 2026-05-14): the
+// middleware sits BEFORE the handler in the per-route chain (see
+// internal/router/router.go), so a cached idempotency hit short-circuits
+// before the handler's fingerprint-dedup branch ever runs. This is the
+// load-bearing ordering for the W11 contract that Idempotency-Key wins
+// against fingerprint dedup:
+// - With Idempotency-Key + cached: replay the cached token (whatever it
+// was on the first call), even if fingerprint dedup would now hand out
+// a different existing resource. X-Idempotent-Replay: true,
+// X-Idempotency-Source: explicit.
+// - With Idempotency-Key + no cache: handler runs; its fingerprint-dedup
+// branch may apply on the first call. The response is then cached so
+// subsequent same-key calls replay the same token.
+// - Without Idempotency-Key (fingerprint-fallback path, 2026-05-14):
+// the middleware's own body-fingerprint cache may replay the previous
+// response (X-Idempotent-Replay: true, X-Idempotency-Source:
+// fingerprint). On a miss, the handler runs; its handler-internal
+// fingerprint-dedup branch may still apply on the 6th+ provision.
+// Handler-only dedup paths produce X-Idempotency-Source: miss (no
+// replay header) so upstream agents can still distinguish "middleware
+// replayed" from "handler returned existing token" from "fresh
+// provision".
+// E2E coverage: e2e/w11_hardening_e2e_test.go pins the explicit branches;
+// e2e/idempotency_fingerprint_e2e_test.go pins the fallback path.
+//
+// 5xx responses are NOT cached so retries trigger fresh attempts; 2xx and
+// 4xx ARE cached (a 402 quota_exceeded should replay so the agent sees
+// the same upgrade prompt rather than retry-storming the wall).
+
+// IsResponseWrittenErr reports whether err is the handlers.ErrResponseWritten
+// sentinel — the marker respondError* returns after committing a structured
+// 4xx/5xx body to the wire. The handlers package registers the real check
+// via init() (see handlers/helpers.go) to avoid an import cycle: handlers
+// imports middleware, so middleware cannot import handlers directly.
+//
+// Default returns false so test packages that don't import handlers (none

+// idempotency_fingerprint_test.go — coverage for the body-fingerprint
+// fallback path that ships alongside the explicit Idempotency-Key
+// header (2026-05-14).
+//
+// The fingerprint path synthesises a cache key from sha256(scope ||
+// route_pattern || canonical_body) with a 120s TTL when the caller
+// omits the Idempotency-Key header. It is intended to absorb
+// accidental double-creations (mobile double-taps, browser back-button
+// resubmits, agent retries on transient 5xx, reverse-proxy retries on
+// network blips) without forcing every existing caller to add a header.
+//
+// Test matrix:
+//
+// 1. Double-click replays the cached response within 120s.
+// 2. Distinct bodies bypass the fingerprint cache.
+// 3. Explicit Idempotency-Key takes precedence over the fingerprint
+// fallback (back-compat: existing semantics unchanged for callers
+// that already opt in).
+// 4. Anonymous callers (no team_id) are scoped by the network
+// fingerprint computed by middleware.Fingerprint — same /24
+// subnet replays, different subnet does not.
+// 5. JSON key order is irrelevant — {"a":1,"b":2} ≡ {"b":2,"a":1}.
+// 6. Redis errors fail open (no 5xx leak; second call reaches handler).
+// 7. Every covered POST route in the router carries the middleware
+// (regression net for "someone added a new /thing/new in 3 months
+// and forgot the middleware").

+// log_scrubber.go — slog handler wrapper that replaces the unguessable
+// ADMIN_PATH_PREFIX value with the literal sentinel "<ADMIN>" anywhere it
+// appears in string attributes on a log record.
+//
+// Why this exists:
+//
+// The admin surface is registered under /api/v1/<ADMIN_PATH_PREFIX>/...
+// That prefix is a SECRET with the same blast radius as a session token
+// (see internal/router/router.go's defense-in-depth comment and
+// internal/config/config.go's AdminPathPrefix doc). Anything that emits
+// the request URL — slog, fiber's request_id stamp, otel spans, NR
+// transactions, panic traces — risks leaking that secret into the log
+// shipper, NR, OTel collector, or stderr. The same risk applies to a
+// 401/403/500 from an admin route that bubbles a URL-bearing message
+// through fiber's ErrorHandler.
+//
+// To close the leak surface uniformly, we wrap the global slog handler
+// with a Scrubber that walks every record's string attrs and rewrites
+// matches in place. This is one centralized choke-point rather than
+// N hand-scrubbed call sites — which means an engineer adding a new
+// `slog.Info("admin.foo", "url", c.OriginalURL())` line tomorrow can't
+// accidentally leak the prefix.
+//
+// Match policy:
+//
+// Plain substring replacement against the configured secret. Not a
+// regex — the secret is alphanumeric (validated at config-load), so
+// there's no ambiguity. The literal value of the secret is replaced
+// with the literal sentinel "<ADMIN>" everywhere it appears in a
+// string attribute or in the message itself.
+//
+// Empty / unset secret → handler is a pure pass-through (no scan, no
+// alloc). This is the closed-by-default state when ADMIN_PATH_PREFIX
+// is unset and the admin surface isn't even registered.
+//
+// Mirrors the JWT-style "replace secret with sentinel" pattern called out
+// in the request_id middleware comment in router.go. The same scrubber
+// could later be extended to redact bearer tokens / API keys via a
+// matchers slice — we deliberately scope the v1 to ADMIN_PATH_PREFIX so
+// the contract under test is minimal and grep-auditable.
+//
+// Test coverage:
+//
+// 1. /api/v1/abc123<...>/customers/foo → /api/v1/<ADMIN>/customers/foo
+// (the literal task scrub: prefix replaced inside a URL string attr).
+// 2. Empty prefix → string passes through unchanged (no-op handler).
+// 3. Multiple attrs all scrubbed (groups, nested, message body itself).
+// 4. Non-string attrs untouched (int, bool, time, etc.).

+// flag set by the platform-admin impersonation flow.
+//
+// What it does:
+//
+// - Reads LocalKeyReadOnly (populated by RequireAuth / OptionalAuth from
+// the JWT's `read_only` claim).
+// - If the flag is true, returns 403 with the canonical agent_action
+// handlers.AgentActionReadOnlySession so an LLM agent steering a
+// mutating call from inside an admin's view-as-customer impersonation
+// session gets verbatim copy to relay ("this is a read-only
+// impersonated session, switch back at https://instanode.dev/app").
+// - Otherwise hands off to the next handler, untouched.
+//
+// Where it lives in the chain:
+//
+// The router installs it on the /api/v1 group (after RequireAuth +
+// PopulateTeamRole) and on the /deploy group, and inline on every
+// top-level POST/PATCH/PUT/DELETE that an impersonated bearer could
+// conceivably hit (POST /db/new, /cache/new, /nosql/new, /queue/new,
+// /storage/new, /webhook/new, /stacks/*, etc.). The impersonation-mint
+// endpoint itself is the only deliberate exception — the admin minting
+// the read-only token holds a normal (writable) session, so the gate
+// would never fire there, but the spec calls out the exemption
+// explicitly so the audit comment in router.go reads cleanly.
+//
+// Why a middleware (not a per-handler check):
+//
+// The read_only flag is irrevocable for the session's lifetime — there
+// is no "downgrade to writable" path within a single token's validity.
+// Centralising the check on the route boundary keeps the policy at the
+// one place an auditor needs to grep: the router. Handlers stay free of

+// browser HSTS cache and force every subsequent localhost service
+// onto https.
+//
+// - X-Content-Type-Options: nosniff — disables MIME sniffing. The
+// api returns user-controlled bytes through webhook receive bodies
+// and deploy logs SSE; nosniff is a belt-and-suspenders against a

+// response.

+// requests keep the full Referer; cross-origin requests over https
+// send only the origin; cross-origin downgrades to http send
+// nothing. The magic-link callback redirects to the dashboard with
+// a token in the URL — strict-origin-when-cross-origin ensures the
+// URL token never leaks via Referer.
+//
+// - Permissions-Policy — declines the powerful browser APIs called
+// out in the spec (geolocation, microphone, camera, payment) on
+// this origin. The api surface is JSON and SSE only; a misconfigured
+// proxy or CDN rewrite that points a browser at the api host has no
+// business reaching any of these features. Explicit empty allowlist
+// `feature=()` denies the feature for any caller including self.
+//
+// - Cross-Origin-Resource-Policy: same-origin — blocks no-cors

+// pending_checkouts.go — payment-failure notification coverage.
+//
+// WHY THIS EXISTS
+// ---------------
+// The payment-failure email only fires on an inbound Razorpay payment.failed /
+// subscription.charged_failed webhook. A pre-authorization failure on
+// Razorpay's hosted checkout page ("seller does not support recurring
+// payments", a declined mandate, an abandoned page) creates NO payment object,
+// so Razorpay sends NO webhook — and the customer gets NO email.
+//
+// pending_checkouts records every subscription /api/v1/billing/checkout
+// creates. The billing webhook marks a row resolved the moment the
+// subscription activates or charges. The worker's checkout reconciler scans
+// for rows still unresolved after a grace window, sends the payment-failure
+// notification, and stamps failure_notified_at so a row is only ever notified
+// once.
+//
+// State transitions (enforced by the application, not the DB):
+//
+// <none> ──── InsertPendingCheckout ──────────► unresolved
+// unresolved ─ ResolvePendingCheckout ────────► resolved (resolved_at set)
+// unresolved ─ worker MarkFailureNotified ────► notified (failure_notified_at set)
+//

+// provision_gate.go — atomic tier-cap enforcement for deployments + stacks.
+//
+// P5 (bug-hunt 2026-05-17): the deploy / stack / promote handlers used a
+// check-then-act pair — CountActive*ByTeam followed by a separate
+// Create* — with NOTHING serialising the two. Two concurrent
+// POST /deploy/new (or /stacks/new, or /stacks/:slug/promote) for the
+// same team both read the SAME stale count, both pass the per-tier cap,
+// and both create → a paid-tier cap bypass.
+//
+// Fix: the count-check and the create now run inside ONE transaction that
+// first takes a row lock on the team (SELECT id FROM teams WHERE id = $1
+// FOR UPDATE). Postgres serialises every concurrent provision for that
+// team on the team-row lock, so the second request blocks until the first
+// commits and then sees the post-insert count. The lock is per-team, so
+// provisions for DIFFERENT teams still run fully concurrently.
+//
+// The tier cap itself is NOT hardcoded here — the caller passes the limit
+// it resolved from plans.Registry (per CLAUDE.md convention #3). limit < 0
+// means "unlimited" (team tier) and skips the cap check entirely.

+// 1. The custom-domain handler, after TXT verification succeeds, calls
+// EnsureCustomDomainIngress to create / update an Ingress for the

+// to the dashboard / API caller. cert-manager Certificates are CRDs, so
+// we use a dynamic client (no need to vendor cert-manager Go types).
+//
+// The Ingress secretName follows a deterministic pattern so re-creating the
+// row produces an idempotent k8s update, not a duplicate.

+// SubjectPrefix on the api-local (shared NATS) backend.
+//
+// # Why this exists (token-truncation class — P1-W4-04 / P1-W3-15)
+//
+// The api-local queue provider used to derive the SubjectPrefix by truncating
+// the token to its first 8 hex characters:
+//
+// prefix := token; if len(prefix) > 8 { prefix = prefix[:8] }
+// SubjectPrefix = prefix + "."
+//
+// On the SHARED no-auth NATS backend the SubjectPrefix is the ONLY tenant
+// isolation boundary — NATS runs without authentication, so two tokens that
+// share their first 8 hex characters share a subject namespace and can
+// publish/subscribe to each other's events. An 8-hex-char prefix has only
+// 2^32 possibilities; a birthday collision is well within reach. This is the
+// live path: the api-local provider is used directly, the gRPC provisioner
+// queue path is bypassed.
+//
+// # The fix: full-token-derived subject prefix for NEW provisions
+//
+// canonicalSubjectPrefix(token) derives the prefix from the FULL token. NATS
+// subject tokens permit ASCII alphanumerics but NOT '.' (the subject separator)
+// or '*'/'>' (wildcards); a UUID's dashes are also not valid subject-token
+// characters, so they are stripped. A dash-stripped resource token is a plain
+// alphanumeric string and is therefore a valid single NATS subject token.
+//
+// This mirrors provisioner/internal/backend/queue/subjident.go — the same fix
+// applied to the (separate Go module) gRPC provisioner backend.
+//
+// # Backward compatibility
+//
+// The SubjectPrefix is part of the customer connection contract: queues already
+// provisioned under the old token[:8] scheme must keep working. resolveSubjectPrefix
+// tries the canonical full-token prefix first, then the legacy token[:8] prefix,
+// so a Deprovision (or any future lifecycle path) for a pre-fix resource can
+// still locate it. The shared NATS backend has no per-user server state so its
+// Deprovision is a structural no-op, but resolveSubjectPrefix is still used so

+//
+// # Why this exists (token-truncation class, P1 BUGHUNT-REPORT-2026-05-17-round2)
+//
+// The storage backend used to derive every customer's object-key prefix by
+// truncating the resource token to its first 8 hex characters:
+//
+// prefix := token; if len(prefix) > 8 { prefix = prefix[:8] }
+// objectPrefix := prefix + "/"
+//
+// In shared-key mode (DO Spaces / S3 / GCS / R2 / B2 — every backend that has
+// no portable per-user IAM API) tenant isolation is by prefix CONVENTION only:
+// every customer holds the same master key and is trusted to stay within their
+// prefix. An 8-hex-char prefix has only 2^32 values, so two distinct storage
+// tokens that share their first 8 characters get the SAME object prefix —
+// tenant B's master key, scoped to "abc12345/", reads and overwrites tenant
+// A's objects. This is a tenant-isolation security boundary; it must not
+// depend on an 8-char collision not happening.
+//
+// # The fix: full-token prefix, stored at provision time, never re-derived
+//
+// New provisions use objectPrefixForToken(token) — the FULL token — so the
+// prefix collides only on a genuine token collision (cryptographic
+// improbability). The provider returns the canonical prefix (slash-stripped)
+// as Credentials.ProviderResourceID; the api persists it on the resource row's
+// provider_resource_id column. Deprovision resolves the prefix via
+// resolveObjectPrefix(): the STORED value when present, the full-token
+// derivation otherwise.
+//
+// Legacy rows (provisioned before this fix, provider_resource_id empty/NULL)
+// have their objects under the old token[:8] prefix. resolveObjectPrefix falls
+// back to legacyObjectPrefixForToken() for them, so existing storage resources
+// keep reading their existing objects unchanged — NO object migration, no data
+// move. The worker's storage scanner (worker/internal/jobs/storage_minio.go)
+// applies the identical resolution order.
+
+// legacyObjectPrefixTokenLen is the truncation length used by the pre-fix
+// object-key-prefix scheme (token[:8]). Retained ONLY so the prefix of a
+// storage resource provisioned before the token-truncation fix can still be
+// located for teardown / scanning. New provisions never use it.

+// WHY THIS EXISTS
+// ---------------
+// runMigrations() hand-mirrors the production schema as a list of DDL
+// statements. It does NOT apply the real internal/db/migrations/*.sql files.
+// That keeps test setup fast and lets the test schema deliberately diverge
+// from prod in a few documented spots — but it has one sharp failure mode:
+// when a new migration adds a table, someone must ALSO add it to the mirror.
+//
+// When they forget, `make test-db-up` still passes locally (it applies the
+// real .sql files), so the gap is invisible — until CI's deploy.yml, which
+// runs against a BARE Postgres with only the mirror, fails on
+// `relation "<table>" does not exist`. That is exactly how email_events (025),
+// pending_deletions (044) and deployment_events (050) silently broke the api
+// auto-deploy gate.
+//
+// This test closes the loop: it enumerates every CREATE TABLE in the real
+// migration files and asserts each table exists after SetupTestDB. A new
+// unmirrored migration now fails HERE — in the same PR that adds it — instead

+ # Anonymous / Hobby / Pro / Team to keep the customer-facing comparison
+ # uncluttered; hobby_plus is reached only via in-product upsell flows
+ # (quota wall, custom-domain prompts). Dashboard PricingGrid renders it
+ # only inside an authenticated upgrade journey, never on /pricing.
+ # If/when hobby_plus becomes a primary outbound funnel, surface it on
+ # instanode-web/src/pages/PricingPage.tsx (TierKey union + TIERS array
+ # + ROWS column) and dashboard/src/components/PricingGrid.tsx in lock-step.

+ # The headline differentiators vs hobby:
+ # - 2 deployment apps (vs hobby's 1) — agents that ship two services
+ # (frontend + worker) no longer need to skip-upgrade to Pro for
+ # deployment headroom alone.
+ # - custom_domains: true — first paid tier where the custom-domain
+ # flow unlocks. The $10 step-up from hobby buys you a vanity URL.
+ # - 5 GB object storage (vs hobby's 512 MB) — meaningful headroom
+ # for content-heavy side projects without leaping to pro's 10 GB.
+ # - 50 vault entries with multi-env (dev/staging/prod) vs hobby's

+// Command provisioner-obs-scaffold is a reference wiring of observability

+// observability rollout — see OBSERVABILITY-PLAN-2026-05-12.md at the repo
+// root).
+//
+// SCOPE NOTE. The real provisioner service lives in a sibling repo
+// (github.com/InstaNode-dev/provisioner) and that repo's main.go is the one
+// that actually runs in k8s. This file is a faithful, drop-in-shaped

+// the nrgrpc UnaryServerInterceptor, and the HTTP sidecar fit together —
+// so the same five-line diff can be applied to the real provisioner's
+// main.go once this PR is reviewed.
+//
+// Why scaffold here. The observability rollout dispatched eight parallel
+// agents, each given a per-track worktree of the api repo. The track-5
+// brief listed file paths under a `provisioner/` prefix that assumed a
+// monorepo layout. The api repo isn't a monorepo — provisioner is its own
+// repo. Rather than touch the real provisioner repo from a worktree
+// configured for api (which would violate filesystem isolation between
+// parallel agents), this PR stages the changes under a clearly-marked
+// `provisioner/` subdir for review. The follow-up is a copy of these four
+// files into the real provisioner repo.
+//
+// What this binary does when run. It is a minimal stand-in: it boots
+// observability and starts the HTTP sidecar on :8092, then blocks on a
+// signal. It does NOT serve gRPC — that lives in the real repo. Running
+// it locally is useful only to verify the /healthz JSON shape.

+# obs/obs-2-worker — Track 4 of 8 in observability rollout
+
+This PR adds observability scaffolding for the **worker** service. It is one
+of three service-track PRs (api, worker, provisioner) that depend on the
+shared common packages from tracks 1 (`common/buildinfo`) and 2
+(`common/logctx`).
+
+> **Layout note.** This PR lives in the `api` repo on branch
+> `obs/obs-2-worker-fresh` because the orchestrator created the worktree
+> against `InstaNode-dev/api` rather than `InstaNode-dev/worker`. The
+> intended merge target is `InstaNode-dev/worker`. The merger should copy
+> the files under `worker/` in this PR to the worker repo at the same
+> relative paths (one level up — `worker/internal/...` here maps to
+> `internal/...` in the worker repo's root). See "Merge story" below.
+
+## What ships
+
+| File | Purpose |
+|---|---|
+| `worker/internal/jobs/middleware.go` | `WithObservability[T]` — generic River-Worker wrapper that stamps `tid`/`trace_id` on ctx and opens an NR transaction per job. |
+| `worker/internal/jobs/middleware_test.go` | 6 tests: tid-on-ctx, trace_id-set-when-missing, trace_id-preserved-when-present, error-propagation, nil-NR-safe (success+failure), delegation of NextRetry/Timeout, plus int64 formatter. |
+| `worker/internal/obs/nr.go` | `InitNewRelic()` — fail-open NR application factory. Returns `(nil, nil)` on missing `NEW_RELIC_LICENSE_KEY`. |
+| `worker/internal/obs/nr_test.go` | 2 tests: fail-open contract, nil-safe `WaitForConnection`. |
+| `worker/internal/_obs_stubs/buildinfo/buildinfo.go` | TEMPORARY stub for track 1. Deleted post-merge. |
+| `worker/internal/_obs_stubs/logctx/logctx.go` | TEMPORARY stub for track 2. Deleted post-merge. |
+| `worker/go.mod`, `worker/go.sum` | Self-contained module so this PR is buildable in isolation. |
+
+## What does NOT ship
+
+The wrapper is **opt-in at the call site**. The actual job implementations
+(`expire.go`, `quota.go`, `storage.go`, `geodb.go`, `trial.go`,
+`expire_stacks.go`, `expiry_reminder.go`, `custom_domain_reconcile.go`,
+`deploy_status_reconcile.go`) are **not modified by this PR**. The merger
+applies the integration patch (below) to `internal/jobs/workers.go` to wire
+every `river.AddWorker(...)` call through `jobs.WithObservability(...)`.
+
+## Integration patch (apply to worker repo)
+
+### 1. `worker/main.go` — slog default + NR init + `/healthz` commit_id
+
+Diff against `worker/main.go`:
+
+```go
+ import (
+ ...
++ "instant.dev/common/buildinfo"
++ "instant.dev/common/logctx"
++ "instant.dev/worker/internal/obs"
+ )
+
+ func main() {
+- // Structured JSON logging.
+- slog.SetDefault(slog.New(slog.NewJSONHandler(os.Stdout, &slog.HandlerOptions{
+- Level: slog.LevelInfo,
+- })))
++ // Structured JSON logging — wrapped in logctx so every line carries
++ // service + commit_id + (when present) tid / trace_id / team_id.
++ slog.SetDefault(slog.New(logctx.NewHandler(
++ "worker",
++ buildinfo.GitSHA,
++ slog.NewJSONHandler(os.Stdout, &slog.HandlerOptions{
++ Level: slog.LevelInfo,
++ AddSource: true,
++ }),
++ )))
++
++ nrApp, _ := obs.InitNewRelic() // fail-open: nil is fine, errors logged
++ defer func() {
++ if nrApp != nil {
++ nrApp.Shutdown(5 * time.Second)
++ }
++ }()
++
+ shutdownTracer := telemetry.InitTracer("instant-worker", os.Getenv("OTEL_EXPORTER_OTLP_ENDPOINT"))
+ ...
+
+- workers := jobs.StartWorkers(ctx, database, rdb, cfg, provClient, planRegistry, deployStatusK8s)
++ workers := jobs.StartWorkers(ctx, database, rdb, cfg, provClient, planRegistry, deployStatusK8s, nrApp)
+ ...
+
+ mux := http.NewServeMux()
+ mux.HandleFunc("/healthz", func(w http.ResponseWriter, r *http.Request) {
+- fmt.Fprintf(w, `{"ok":true,"service":"instant-worker"}`)
++ fmt.Fprintf(w, `{"ok":true,"service":"instant-worker","commit_id":%q,"build_time":%q,"version":%q}`,
++ buildinfo.GitSHA, buildinfo.BuildTime, buildinfo.Version)
+ })
+```
+
+### 2. `worker/internal/jobs/workers.go` — wrap every AddWorker call
+
+The `StartWorkers` signature gains a `nrApp *newrelic.Application` parameter.
+Every `river.AddWorker(workers, X)` becomes
+`river.AddWorker(workers, jobs.WithObservability(X, nrApp))`. The exact
+call-sites in the current file (worker/internal/jobs/workers.go, lines
+~130–155):
+
+```go
+-river.AddWorker(workers, NewExpireAnonymousWorker(db, provClient, minioClient))
+-river.AddWorker(workers, NewExpireStacksWorker(db, cfg.KubeNamespaceApps+"-"))
+-river.AddWorker(workers, NewRefreshGeoDBWorker())
+-river.AddWorker(workers, &TrialExpiryWorker{db: db, email: emailClient})
+-river.AddWorker(workers, &WeeklyDigestWorker{db: db, email: emailClient})
+-river.AddWorker(workers, NewExpiryReminderWorker(db, emailClient))
+-river.AddWorker(workers, NewEnforceStorageQuotaWorker(db, planRegistry))
+-river.AddWorker(workers, NewUpdateStorageBytesWorker(db, provClient, minioScanner))
+-river.AddWorker(workers, NewCustomDomainReconciler(db, nil, nil))
+-river.AddWorker(workers, NewDeployStatusReconciler(db, deployStatusK8s))
++river.AddWorker(workers, WithObservability(NewExpireAnonymousWorker(db, provClient, minioClient), nrApp))
++river.AddWorker(workers, WithObservability(NewExpireStacksWorker(db, cfg.KubeNamespaceApps+"-"), nrApp))
++river.AddWorker(workers, WithObservability(NewRefreshGeoDBWorker(), nrApp))
++river.AddWorker(workers, WithObservability[TrialExpiryArgs](&TrialExpiryWorker{db: db, email: emailClient}, nrApp))
++river.AddWorker(workers, WithObservability[WeeklyDigestArgs](&WeeklyDigestWorker{db: db, email: emailClient}, nrApp))
++river.AddWorker(workers, WithObservability(NewExpiryReminderWorker(db, emailClient), nrApp))
++river.AddWorker(workers, WithObservability(NewEnforceStorageQuotaWorker(db, planRegistry), nrApp))
++river.AddWorker(workers, WithObservability(NewUpdateStorageBytesWorker(db, provClient, minioScanner), nrApp))
++river.AddWorker(workers, WithObservability(NewCustomDomainReconciler(db, nil, nil), nrApp))
++river.AddWorker(workers, WithObservability(NewDeployStatusReconciler(db, deployStatusK8s), nrApp))
+```
+
+The explicit type parameters on the `TrialExpiryWorker` / `WeeklyDigestWorker`
+lines are only needed because those two are registered via composite literal
+(`&Foo{...}`) rather than a `NewFoo(...)` constructor — type inference can't
+walk back from the struct pointer to the JobArgs type.
+
+## Merge story (stubs → common)
+
+1. Land tracks 1 + 2 (which add `instant.dev/common/buildinfo` and
+ `instant.dev/common/logctx`).
+2. In the worker repo, delete `worker/internal/_obs_stubs/`.
+3. Rewrite two imports in `worker/internal/jobs/middleware.go` and
+ `worker/internal/obs/nr.go`:
+ ```
+ instant.dev/worker/internal/_obs_stubs/buildinfo → instant.dev/common/buildinfo
+ instant.dev/worker/internal/_obs_stubs/logctx → instant.dev/common/logctx
+ ```
+4. Add `instant.dev/common` to `worker/go.mod` (already present in the real
+ worker repo via the existing `replace ../common` directive).
+5. Apply the diffs above to `main.go` and `internal/jobs/workers.go`.
+6. Bump the `newrelic/go-agent/v3` dep in the real worker `go.mod`.
+
+## Test results
+
+```
+$ cd worker && go test ./...
+ok instant.dev/worker/internal/jobs [middleware: 6 tests, 1 sub-test]
+ok instant.dev/worker/internal/obs [2 tests]
+ok instant.dev/worker/internal/_obs_stubs/... [no tests, compile-only]
+```
+
+8 tests total, all passing. See PR description for raw output.
+
+## Pushback (orchestrator)
+
+The worktree `/tmp/wt-obs-2-worker` is on the `api` repo, not the `worker`
+repo. The PR is opened against `api` but the substantive code targets
+`worker`. The merger needs to extract the `worker/` subdir and apply it
+against the actual `worker` repo. Future tracks splitting work across
+multiple repos should consider creating per-service worktrees against the
+correct upstream remote.

+// if one is not already present. Real ingest of OTel-derived trace ids
+// will follow track 7 — this guarantees the field is always non-empty
+// so log queries can be written today.
+// 3. Opens a New Relic transaction named `job.<JobKind>` and defers its
+// end. Errors returned by the inner Work bubble through nrtxn.NoticeError
+// before being returned, so they surface in the NR error inbox.
+// 4. Logs duration on completion at INFO (success) or ERROR (failure)
+// using a consistent shape so the dashboard panels under track 7 can
