+    "body": "# Retry and timeout standard\n\nApplies to every cross-service call in the NovaCart fleet. Two config keys per\ndownstream dependency, named after the downstream service.\n\n## The two keys\n\nFor a caller talking to downstream service `X`:\n\n- `<downstream>_retry_max_attempts` - **must be 3**\n- `<downstream>_timeout_ms` - **must be at most 2000**\n\nSo `payments` calling `notifications` runs with\n`notifications_retry_max_attempts=3` and `notifications_timeout_ms=2000` (or\nlower). `checkout` calling `payments` runs with `payments_retry_max_attempts=3`\nand `payment_timeout_ms` inside the 2000ms ceiling.\n\nRetries use exponential backoff with jitter; the backoff schedule is applied\nautomatically by the shared HTTP client, so you do not configure delays. Three\nattempts means one initial call plus two retries, worst case roughly\n`3 * timeout_ms` plus backoff.\n\n## Why 3 and why 2000\n\n**A retry value of 0 means one timeout permanently fails the request.** There is\nno second chance. A single blip in a downstream - a pod restart, a brief GC\npause, a rebalanced connection - becomes a user-visible failure and a failed\norder. This is not hypothetical: payments ran with\n`notifications_retry_max_attempts=0` and `notifications_timeout_ms=30000` for\nseveral weeks and pushed `error_rate_pct` from a baseline of 0.4% to 3.8%,\nstraight through the 1.0% SLO.\n\nThe 2000ms ceiling exists because timeouts multiply up the call stack. A 30000ms\ntimeout on a leaf call does not \"wait patiently\" - it holds a request-handling\nworker and a database connection for thirty seconds, and under load that is how\nyou exhaust a pool (see \"Connection pool sizing\"). If a downstream genuinely\ncannot answer in two seconds, the call belongs on a queue, not in the request\npath.\n\n## Checklist for a new dependency\n\n1. Add `<downstream>_retry_max_attempts=3` to the caller's config.\n2. Add `<downstream>_timeout_ms` at or below 2000.\n3. Confirm the call is idempotent, or that the downstream deduplicates by\n   idempotency key. Retrying a non-idempotent write is worse than failing.\n4. Confirm the caller's own inbound timeout is larger than\n   `attempts * timeout_ms` plus backoff, or the retry budget is fiction.\n5. Add the dependency to the service's dependency section in its design doc.\n\n## Anti-patterns\n\n- Retrying on 4xx. Only retry timeouts, connection errors, 429, and 5xx.\n- Retrying inside a retry. Nested retries multiply: 3 x 3 = 9 calls.\n- Raising the timeout to \"fix\" a slow downstream. Fix the downstream.\n"

+    "day": 226,
+    "body": "# Queue consumer tuning\n\nOwner: platform. Primary consumer service: `notifications` (tier 2), which\ndrains the email, SMS, and push delivery queues. The same rules apply to any\nservice that consumes from the message broker.\n\n## The rule\n\n`prefetch_count` must be a **bounded** value. **Recommended: 50.**\n\n`prefetch_count=0` means **unlimited prefetch** and is the single worst setting\nin this runbook.\n\n## What prefetch does\n\nPrefetch is the number of unacknowledged messages the broker will push to a\nsingle consumer. With `prefetch_count=50`, a consumer holds at most 50\nin-flight messages; the broker will not send a 51st until one is acknowledged.\nThis is the backpressure mechanism - it is what lets a slow consumer tell the\nbroker to slow down.\n\nWith `prefetch_count=0` there is no backpressure. The broker pushes the entire\nbacklog to whichever consumer connects first. Consequences, all of which we have\nseen in `notifications`:\n\n- **Memory pressure.** A 400k-message backlog lands in one process's heap. RSS\n  climbs until the container hits its memory limit.\n- **Consumer restarts.** The container is OOM-killed, the unacknowledged\n  messages are redelivered, the restarted consumer grabs them all again, and it\n  is killed again. A restart loop that looks like a broker problem and is not.\n- **Terrible load distribution.** One consumer holds everything while its\n  siblings sit idle, so scaling out does nothing.\n- **Head-of-line latency.** A high-priority message sits behind 400k others.\n\n## Sizing\n\n| Message profile                | prefetch_count |\n| ------------------------------ | -------------- |\n| Fast, uniform (a few ms each)  | 100-200        |\n| Standard delivery work         | **50**         |\n| Slow or variable (seconds)     | 5-10           |\n| Long-running jobs (minutes)    | 1              |\n\nRule of thumb: `prefetch_count` should be roughly the number of messages a\nconsumer can process in one to two seconds. Start at 50 and adjust with\nevidence.\n\n## Related settings\n\n- `smtp_pool` on `notifications` bounds concurrent SMTP connections. Prefetch\n  above the SMTP concurrency just buys queueing inside the process.\n- Ack **after** the work is done, never on receipt. Acking on receipt turns a\n  crash into silent message loss.\n- Dead-letter after 5 delivery attempts so a poison message cannot loop forever.\n\n## Changing it\n\nRepo config: PR with a `config` change, CI, merge, staging, production.\n`notifications` is tier 2 - straight 100% deploy after staging. Watch consumer\nmemory and queue depth for one full peak after the change.\n"

+    "body": "# Checkout architecture\n\nService: `checkout` (tier 1, python, commerce). Owns the cart and the checkout\norchestration state machine. SLOs: `error_rate_pct < 1.0`,\n`latency_p99_ms < 400`.\n\n## Responsibilities\n\n`checkout` owns the transition from \"a cart exists\" to \"an order exists and is\npaid\". It does not own money movement (that is `payments`), product data (that\nis `catalog`), or customer notification (that is `notifications`). It owns the\nsequencing and the guarantee that the sequence happens exactly once.\n\nModules: `cart`, `checkout_flow`, and - once the loyalty program ships -\n`loyalty_redeem`.\n\n## The state machine\n\nEvery checkout session is a row with an explicit state:\n\n```\ncart_open -> pricing_locked -> payment_pending -> paid -> order_created\n                   |                   |\n                   +-> abandoned       +-> payment_failed\n```\n\nTransitions are append-only and each is stamped with the idempotency key of the\nrequest that caused it. Replaying a request that has already produced a\ntransition returns the existing result rather than performing it again. This is\nwhat makes the checkout endpoint safe to retry, which matters because clients\nretry aggressively on mobile networks.\n\n## Dependencies\n\n| Downstream      | Call                     | Timeout budget            |\n| --------------- | ------------------------ | ------------------------- |\n| `catalog`       | price and availability   | `<= 2000ms`, 3 attempts   |\n| `payments`      | authorize and capture    | `payment_timeout_ms`      |\n| `notifications` | order confirmation       | async, fire-and-forget    |\n\nAll synchronous calls follow the \"Retry and timeout standard\": three attempts,\ntimeout at or below 2000ms. The `notifications` call is deliberately\nasynchronous - a confirmation email must never be able to fail an order.\n\n## Pricing lock\n\nAt `pricing_locked` we snapshot the price, the promotion, and the tax\ncomputation into the session row. From that point the customer pays the price\nthey were shown even if `catalog` changes underneath. The lock expires after 20\nminutes, after which the session re-prices.\n\n## Failure handling\n\n- `payments` timeout: the session stays `payment_pending` and a reconciliation\n  job asks `payments` for the authoritative status. We never assume a timeout\n  means \"did not happen\".\n- `catalog` unavailable: fail closed. We do not sell at a guessed price.\n- Partial capture: not supported; a capture is all-or-nothing per order.\n\n## Feature flags\n\nCheckout-adjacent behavior ships behind flags - `instant_refunds`,\n`express_checkout`. Per the \"Feature flags\" runbook, the code deploys first and\nthe flag is enabled afterwards at no more than 10%. `instant_refunds` is the\ncautionary tale: ramped to 100% in production, it took `error_rate_pct` from\n0.3% to 5.5% via a nil-pointer panic in the refund worker.\n\n## Open questions\n\n- Should the pricing lock move into `catalog` so `search` can honor it too?\n- Cart merge on login is still last-write-wins; it should be a real merge.\n"

There is no shared\nlibrary; the contract between them is the points-rate field on the product\npayload and the redeem call on the checkout API.\n\n## Why this split\n\nAccrual rules are product data - they vary per product and per category, they\nchange with merchandising campaigns, and they belong next to pricing. Redemption\nis an order-level money decision and belongs in the checkout state machine.\nDisplay is display. Putting accrual in `checkout` would have meant `checkout`\nreading the product rules table, which is exactly the coupling we spent last\nyear removing.\n\n## Rollout order\n\nDeployment order matters and is not negotiable:\n\n**`catalog` - then `checkout` - then `storefront-web`.**\n\nThe reasoning is a strict data dependency chain:\n\n1. `catalog` must be emitting a points rate on the product payload before\n   `checkout` can compute a balance to redeem against. If `checkout` ships\n   first, every redeem attempt reads a missing field and either errors or\n   silently computes zero.\n2. `checkout` must expose the redeem endpoint and be live before\n   `storefront-web` renders a redeem button. If the widget ships first,\n   customers see a button that 404s - a visible, embarrassing failure on the\n   busiest page we have.\n\n`catalog` is tier 2 (straight production deploy after staging). `checkout` and\n`storefront-web` are tier 1, so each is staging-first, then a production canary\nat `canary_percent <= 25`, `assess_canary`, then `promote_canary` - see\n\"Deployment policy\". Do not begin the next service's production deploy until the\nprevious one is fully promoted.\n\n## Points model\n\nBalances live in an append-only ledger, mirroring the approach in \"Payments\nsettlement pipeline\": `earn`, `redeem`, `expire`, `adjust`. Balance is the sum,\nnever a stored counter. Redemption is authorized at `pricing_locked` and\ncommitted at `paid`; an abandoned cart releases the hold after 20 minutes.\n\nDefault rate is 1 point per whole currency unit, 100 points equals one currency\nunit of discount, points expire 12 months after earning. Maximum redemption is\n50% of order subtotal.\n\n## Risks\n\n- Double-redeem across concurrent sessions. Mitigated by the hold and by the\n  idempotency key on the checkout transition.\n- Accrual rule changes retroactively altering historical balances. The ledger\n  stamps the rate version at earn time.\n"

The alias swap invalidated the entire query cache. Every in-flight query\nmissed simultaneously and hit the primary index, driving `latency_p99_ms` from\n~210ms to a peak of 2100ms and firing the `search latency_p99_ms` alert against\nits 300ms SLO. Search was slow, not down; conversion on search-originated\nsessions dropped an estimated 18% for the duration.\n\n## Timeline (UTC)\n\n- **14:02** Engineer starts a full index rebuild for an analyzer change. Routine;\n  done a dozen times before.\n- **14:41** Rebuild completes. Alias swaps to the new index. Query cache keys are\n  namespaced by index generation, so the swap invalidates 100% of the cache.\n- **14:42** `latency_p99_ms` crosses 300ms. Alert fires, `medium`.\n- **14:44** On-call acknowledges. Initial hypothesis: the new analyzer is slow.\n- **14:51** Index CPU is pegged; per-query cost is unchanged from before the\n  rebuild. Hypothesis discarded - it is volume, not per-query cost.\n- **14:58** Cache hit ratio confirmed at 3%, against a normal 76%. Root cause\n  identified.\n- **15:06** Traffic to search temporarily shed at the gateway by 30% to let the\n  cache refill.\n- **15:16** Hit ratio back above 60%; p99 at 340ms and falling.\n- **15:22** Shedding removed. p99 at 215ms.\n- **15:26** Alert resolved, incident resolved, update posted in `#incidents`.\n\n## Root cause\n\nThe query cache is namespaced by index generation. An alias swap therefore\nperforms a **complete, instantaneous cache flush** with no warm-up. Because the\ncache normally absorbs about **75% of index load**, the index was asked to serve\nroughly 4x its steady-state query volume within one second. Requests queued,\nlatency rose, clients retried, and the retries added load - a classic stampede\nwith a positive feedback loop.\n\n## Contributing factors\n\n- No warm-up step in the rebuild procedure. The runbook ended at \"swap alias\".\n- Rebuild was run at 14:00 local, in the daily traffic ramp, because the job\n  takes 40 minutes and nobody wanted to babysit it at night.\n- Single-flight coalescing existed for identical concurrent queries but the\n  stampede was across *thousands of distinct* queries, so coalescing did nothing.\n- No alert on cache hit ratio, so the actual signal was invisible for 14 minutes.\n\n## What went well\n\n- Alerting fired within a minute of the SLO breach.\n- Load shedding at the gateway was the correct blunt instrument and worked.\n\n## Action items\n\n1. Add a **warm-up phase** to the rebuild: replay the top 5000 queries against\n   the new index before swapping the alias. **Done.**\n2. Add **+/-10% TTL jitter** to `cache_ttl_s=300` so natural expiry never\n   synchronizes. **Done.**\n3. Alert on **cache hit ratio below 50%** for 5 minutes. **Done.**\n4. Move scheduled rebuilds to 03:00-05:00 UTC. **Done.**\n5. Document the stampede risk in the \"Search caching\" runbook. **Done.**\n"

The migration was applied to production before the\ndeploy, as policy requires - but the migration was **not backwards compatible**\nwith the code version already running. Between the migration completing and the\nnew version being fully rolled out, the running `v1.7.6` instances queried a\ncolumn that no longer existed. Product-detail and category pages returned 500s;\n`checkout` fell back to failing closed on pricing, per its design.\n\n## Timeline (UTC)\n\n- **09:12** `apply_migration(catalog, production, 0043)` starts.\n- **09:13** Migration completes. Column renamed.\n- **09:13** `v1.7.6` instances begin throwing\n  `UndefinedColumn: price_cents` on every pricing query.\n- **09:14** `catalog` error rate goes vertical. `checkout` starts failing closed.\n  Two alerts fire.\n- **09:15** Deploy of `v1.8.0` starts, as planned, but rolls instance by instance.\n- **09:17** On-call acknowledges, declares sev1.\n- **09:19** Commander recognizes the pattern: schema ahead of code, partial fleet.\n- **09:21** Decision: do **not** attempt to reverse the migration. Accelerate the\n  `v1.8.0` rollout instead.\n- **09:31** Rollout complete on all instances. Errors stop.\n- **09:34** Metrics confirmed recovered; alerts resolved; incident resolved.\n- **09:40** Update posted in `#incidents`; status page updated and cleared.\n- Later that day: `v1.8.0` was rolled back for an unrelated defect found in\n  review, which is when the second lesson landed - the rolled-back `v1.7.6` code\n  could not read the renamed column either, and a hotfix `v1.8.1` had to be cut\n  because **migrations are forward-only** and there was no going back.\n\n## Root cause\n\nA **destructive, non-backwards-compatible schema change shipped in one step**. A\ncolumn rename is two incompatible states with no overlap: code that knows the old\nname and code that knows the new name cannot both work against the same schema.\nAny window in which both code versions run - and a rolling deploy guarantees such\na window - is an outage.\n\n## Contributing factors\n\n- The \"migration before code\" rule was followed correctly, and following it\n  correctly was *insufficient*. The rule says nothing about compatibility with\n  the code already running.\n- The migration had one reviewer, from the authoring team.\n- Rolling deploys were assumed to be fast enough not to matter. They are not.\n- `catalog` is tier 2, so there was no canary to catch it at 25%.\n\n## What went well\n\n- Nobody tried to hand-write a reverse migration under pressure. Rolling forward\n  was the right call and it was made in six minutes.\n- `checkout` failing closed on pricing prevented selling at a wrong price.\n\n## Action items\n\n1. Write the **N-1 rule** into the \"Database migration policy\": every migration\n   must leave the schema usable by the currently deployed code. **Done.**\n2. Mandate the **expand/contract** pattern for renames: add column, dual-write,\n   backfill, switch reads, drop in a later migration. **Done.**\n3. Require a **second reviewer from platform** for migrations on tables above ten\n   million rows. **Done.**\n4. Add a CI check that flags `DROP COLUMN`, `RENAME COLUMN`, and new `NOT NULL`\n   constraints for explicit sign-off. **Done.**\n"

+    "body": "# API deprecation\n\nHow to retire a public endpoint without breaking integrators. Traffic weights\nlive in `api-gateway` production runtime state; endpoint status lives in the\nrepo.\n\n## The three phases\n\n### 1. Deprecate and deploy\n\nMark the endpoint `deprecated` via an `endpoint` PR change, and **deploy that\nfirst**. Deprecation is a real code change: the gateway starts emitting\n`Deprecation` and `Sunset` response headers, the endpoint is flagged in the\npublic API reference, and usage is tagged by client id so we can see who is\nstill on it. `api-gateway` is tier 1, so this deploy is staging first, then a\nproduction canary at `canary_percent <= 25`, `assess_canary`, `promote_canary`.\n\nDo not shift any traffic yet. Deprecated is a label, not a redirect.\n\n### 2. Shift traffic in stages\n\nMove traffic from the legacy endpoint to its replacement in steps of **at most\n50 percentage points per step**. A typical path is 100 - 50 - 0 with a soak in\nbetween, and for a high-volume endpoint 100 - 75 - 50 - 25 - 0 is better.\n\nAt each step:\n\n- Watch the replacement's error rate and p99 for at least one traffic peak.\n- Compare response shapes on a sample of real requests.\n- If anything regresses, shift back. Shifting back is free and instant.\n\nThe two endpoints' weights should sum to 100 at every step. A step larger than\n50 points is rejected - it is the difference between a bad hour and a bad\nquarter.\n\n### 3. Retire\n\n**Only when the legacy endpoint serves 0% traffic may it be retired.** Retire it\nwith a second `endpoint` PR change (status `retired`) and deploy that change,\nstaging first, canary, promote.\n\n**CI blocks retiring an endpoint that is still serving traffic.** The check\nreads the production traffic weight for the endpoint and fails the run if it is\nnon-zero. This is not overridable; get the weight to 0 first.\n\n## Communication\n\n- Announce in `#eng` when the deprecation deploy lands.\n- Give external integrators a minimum 90-day sunset window from the date the\n  `Sunset` header first ships.\n- Update the public API spec in the same sprint - see \"Public Orders API\".\n\n## Worked example\n\n`/v1/orders` to `/v2/orders`: deprecate `/v1/orders` and deploy; shift\n`/v1/orders` 100 to 50 while `/v2/orders` goes 0 to 50; soak; shift to 0/100;\nsoak; retire `/v1/orders` and deploy.

It is\nworse than a failing test, because it teaches the team to ignore red builds.\n\n## Diagnose from CI history\n\nStart with `list_ci_runs` for the service. You are looking for the same test\nname alternating between `passed` and `failed` across runs on the same commit or\nadjacent commits. The CI detail line usually names it:\n\n```\nintermittent failure: test_checkout_idempotency (rerun may pass)\n```\n\nCommon root causes, roughly in order of how often we hit them:\n\n1. **Shared mutable fixture state** - two tests write the same row, key, or temp\n   file, and ordering decides who wins. The `test_checkout_idempotency` flake was\n   a nondeterministic idempotency-key collision in the fixture.\n2. **Time and timezone** - `now()` at a boundary, tests that assume ordering by\n   second-resolution timestamps.\n3. **Unseeded randomness** - random ids that occasionally collide.\n4. **Real sleeps and races** - `sleep(0.1)` standing in for a synchronization\n   point.\n5. **Network or clock dependence** - a test that quietly reaches a real service.\n\n## Fix the root cause\n\nShip the fix as a PR containing a `test_fix` change with **action `fix`**. The\nchange should make the test deterministic: seed the randomness, isolate the\nfixture per test, inject the clock, replace sleeps with explicit waits.\n\n**Quarantine is a last resort.** A `test_fix` change with action `quarantine`\nstops the test from blocking CI, but it **does not close the ticket** - the\nticket stays open until an action `fix` change lands. Quarantine is for\nunblocking a release train at 2am, not for closing your backlog. Quarantined\ntests are reviewed weekly and anything quarantined for more than two weeks is\nescalated to the owning team's lead.\n\n## Prove stability\n\nAfter merging, demonstrate stability with **3 consecutive green main-branch\nruns**: `run_ci(service=...)` three times, all `passed`, with no other change in\nbetween. One green run proves nothing about a test that fails half the time -\nthree consecutive greens give roughly 87% confidence for a 50% flake and much\nmore for the typical 10-20% flake.\n\nOnly then close the ticket.\n\n## Prevention\n\n- No shared fixtures across test files; build state per test.\n- Inject the clock, never call `now()` directly in application code under test.\n- Seed every random source in the test harness.\n- If a test needs a real dependency, it is an integration test - label it and\n  run it in the integration stage.\n"

+    "service": "",
+    "author": "Priya Nair",
+    "day": 236,
+    "body": "# Connection pool sizing\n\nApplies to every service holding a database connection pool. The relevant config\nkey is `db_pool_size`.\n\n## The rule\n\n`db_pool_size` must be **at least 20** for tier-1 and tier-2 services. Below\nthat, requests queue and time out under normal traffic - not peak traffic,\nnormal traffic.\n\n## Why 20\n\nThe pool is the number of database connections a single service instance may\nhold concurrently. When every connection is checked out, the next request waits\non the pool's acquire queue. That wait is invisible in database metrics - the\ndatabase looks idle and healthy - and shows up only as application latency and\ntimeouts. It is one of the most consistently misdiagnosed failures we have.\n\nRough sizing arithmetic: a service handling 200 requests per second per instance\nwith a 40ms mean query time needs about `200 * 0.04 = 8` connections just to\nkeep up in steady state. Traffic is bursty, queries are not uniform, and one\nslow query holds a connection for its full duration, so we take a 2-3x headroom\nfactor. Twenty is the resulting floor for anything customer-facing.\n\n## Symptoms of an undersized pool\n\n- Application p99 climbs while the database's own p99 is flat.\n- Errors are `TimeoutError` on acquire, not on query execution.\n- Latency is highly sensitive to a small change in traffic - a 10% traffic\n  increase doubles p99. Queueing systems behave like this near saturation.\n- Restarting the service \"fixes\" it for a few minutes.\n\n## Upper bound\n\nBigger is not automatically better. Total connections to the primary is\n`instances * db_pool_size` and the database has a hard `max_connections`. Past\nthat ceiling, connection attempts are refused outright, which is a far worse\nfailure than queueing. Before raising a pool above 50 per instance, check the\ninstance count and the database limit, and consider a connection proxy instead.\n\n## Interaction with timeouts\n\nPool sizing and the \"Retry and timeout standard\" are the same problem seen from\ntwo directions. A downstream call with a 30000ms timeout holds its request\nworker - and any connection that worker checked out - for thirty seconds. A\nhandful of those exhausts a 20-connection pool. Keeping\n`<downstream>_timeout_ms` at or below 2000 is part of pool hygiene.\n\n## Changing it\n\n`db_pool_size` is repo config: PR with a `config` change, CI, merge, deploy\nstaging then production. Measure p99 and the acquire-wait metric before and\nafter; if p99 did not move, the pool was not the bottleneck and you should look\nat query performance instead (see \"Catalog pricing performance\" for the classic\nN+1 case).\n"

+    "body": "# Queue consumer tuning\n\nOwner: platform. Primary consumer service: `notifications` (tier 2), which\ndrains the email, SMS, and push delivery queues. The same rules apply to any\nservice that consumes from the message broker.\n\n## The rule\n\n`prefetch_count` must be a **bounded** value. **Recommended: 50.**\n\n`prefetch_count=0` means **unlimited prefetch** and is the single worst setting\nin this runbook.\n\n## What prefetch does\n\nPrefetch is the number of unacknowledged messages the broker will push to a\nsingle consumer. With `prefetch_count=50`, a consumer holds at most 50\nin-flight messages; the broker will not send a 51st until one is acknowledged.\nThis is the backpressure mechanism - it is what lets a slow consumer tell the\nbroker to slow down.\n\nWith `prefetch_count=0` there is no backpressure. The broker pushes the entire\nbacklog to whichever consumer connects first. Consequences, all of which we have\nseen in `notifications`:\n\n- **Memory pressure.** A 400k-message backlog lands in one process's heap. RSS\n  climbs until the container hits its memory limit.\n- **Consumer restarts.** The container is OOM-killed, the unacknowledged\n  messages are redelivered, the restarted consumer grabs them all again, and it\n  is killed again. A restart loop that looks like a broker problem and is not.\n- **Terrible load distribution.** One consumer holds everything while its\n  siblings sit idle, so scaling out does nothing.\n- **Head-of-line latency.** A high-priority message sits behind 400k others.\n\n## Sizing\n\n| Message profile                | prefetch_count |\n| ------------------------------ | -------------- |\n| Fast, uniform (a few ms each)  | 100-200        |\n| Standard delivery work         | **50**         |\n| Slow or variable (seconds)     | 5-10           |\n| Long-running jobs (minutes)    | 1              |\n\nRule of thumb: `prefetch_count` should be roughly the number of messages a\nconsumer can process in one to two seconds. Start at 50 and adjust with\nevidence.\n\n## Related settings\n\n- `smtp_pool` on `notifications` bounds concurrent SMTP connections. Prefetch\n  above the SMTP concurrency just buys queueing inside the process.\n- Ack **after** the work is done, never on receipt. Acking on receipt turns a\n  crash into silent message loss.\n- Dead-letter after 5 delivery attempts so a poison message cannot loop forever.\n\n## Changing it\n\nRepo config: PR with a `config` change, CI, merge, staging, production.\n`notifications` is tier 2 - straight 100% deploy after staging. Watch consumer\nmemory and queue depth for one full peak after the change.\n"

It does not own money movement (that is `payments`), product data (that\nis `catalog`), or customer notification (that is `notifications`). It owns the\nsequencing and the guarantee that the sequence happens exactly once.\n\nModules: `cart`, `checkout_flow`, and - once the loyalty program ships -\n`loyalty_redeem`.\n\n## The state machine\n\nEvery checkout session is a row with an explicit state:\n\n```\ncart_open -> pricing_locked -> payment_pending -> paid -> order_created\n                   |                   |\n                   +-> abandoned       +-> payment_failed\n```\n\nTransitions are append-only and each is stamped with the idempotency key of the\nrequest that caused it. Replaying a request that has already produced a\ntransition returns the existing result rather than performing it again.

The `notifications` call is deliberately\nasynchronous - a confirmation email must never be able to fail an order.\n\n## Pricing lock\n\nAt `pricing_locked` we snapshot the price, the promotion, and the tax\ncomputation into the session row. From that point the customer pays the price\nthey were shown even if `catalog` changes underneath. The lock expires after 20\nminutes, after which the session re-prices.\n\n## Failure handling\n\n- `payments` timeout: the session stays `payment_pending` and a reconciliation\n  job asks `payments` for the authoritative status. We never assume a timeout\n  means \"did not happen\".\n- `catalog` unavailable: fail closed. We do not sell at a guessed price.\n- Partial capture: not supported; a capture is all-or-nothing per order.\n\n## Feature flags\n\nCheckout-adjacent behavior ships behind flags - `instant_refunds`,\n`express_checkout`. Per the \"Feature flags\" runbook, the code deploys first and\nthe flag is enabled afterwards at no more than 10%. `instant_refunds` is the\ncautionary tale: ramped to 100% in production, it took `error_rate_pct` from\n0.3% to 5.5% via a nil-pointer panic in the refund worker.\n\n## Open questions\n\n- Should the pricing lock move into `catalog` so `search` can honor it too?\n- Cart merge on login is still last-write-wins; it should be a real merge.\n"

A capture is not\n\"a field set to captured\" - it is a sequence of ledger entries that must balance.\nNothing is ever updated in place; corrections are compensating entries. This is\nwhat makes settlement reconcilable at all.\n\nEntry kinds: `authorization`, `capture`, `refund`, `chargeback`, `fee`,\n`payout`. Each carries the processor reference id, the currency, the minor-unit\namount, and the order id.\n\n## Synchronous path\n\n1. `checkout` calls authorize with an idempotency key.\n2. `payments` writes an `authorization` entry and calls the processor through\n   `libpayproc`.\n3. On success, capture is either immediate or deferred to fulfilment depending\n   on the merchant configuration.\n4. `payments` emits an event; `notifications` sends the receipt.\n\nThe call to `notifications` is where this service has historically hurt itself.\nIt must run with `notifications_retry_max_attempts=3` and\n`notifications_timeout_ms` at or below 2000, per the \"Retry and timeout\nstandard\".

They share\nnothing but the index itself, and they are deliberately allowed to fail\nindependently: a stalled ingest means stale results, not an outage.\n\n## Ingest\n\n`catalog` emits product-changed events. The indexer consumes them, hydrates the\nfull product (title, description, attributes, category path, price band,\navailability), and writes into the index across `index_shards=4` shards, keyed\nby product id so a product always lands on the same shard.\n\nTwo modes:\n\n- **Incremental** - the steady state. Event to searchable in under 30 seconds at\n  p95.\n- **Full rebuild** - triggered by a mapping change or an analyzer change. Builds\n  into a new index alias and swaps atomically. A rebuild takes about 40 minutes\n  for the current catalog size.\n\nA rebuild swap invalidates the query cache. That is the dangerous moment; see\n\"Postmortem: search cache stampede after index rebuild\" and the warm-up\nprocedure it produced.\n\n## Query\n\n1. Normalize and analyze the query text.\n2. Check the query cache (`cache_enabled`, `cache_ttl_s=300`).\n3. On miss, fan out to all four shards, gather, and merge.\n4. Rank, apply availability filtering, paginate.\n5.

Weights are versioned\nalongside the index mapping so a ranking change and a mapping change move\ntogether.\n\n## Shard sizing\n\nFour shards is a capacity decision, not a default.

There is no shared\nlibrary; the contract between them is the points-rate field on the product\npayload and the redeem call on the checkout API.\n\n## Why this split\n\nAccrual rules are product data - they vary per product and per category, they\nchange with merchandising campaigns, and they belong next to pricing. Redemption\nis an order-level money decision and belongs in the checkout state machine.\nDisplay is display. Putting accrual in `checkout` would have meant `checkout`\nreading the product rules table, which is exactly the coupling we spent last\nyear removing.\n\n## Rollout order\n\nDeployment order matters and is not negotiable:\n\n**`catalog` - then `checkout` - then `storefront-web`.**\n\nThe reasoning is a strict data dependency chain:\n\n1. `catalog` must be emitting a points rate on the product payload before\n   `checkout` can compute a balance to redeem against. If `checkout` ships\n   first, every redeem attempt reads a missing field and either errors or\n   silently computes zero.\n2. `checkout` must expose the redeem endpoint and be live before\n   `storefront-web` renders a redeem button. If the widget ships first,\n   customers see a button that 404s - a visible, embarrassing failure on the\n   busiest page we have.\n\n`catalog` is tier 2 (straight production deploy after staging). `checkout` and\n`storefront-web` are tier 1, so each is staging-first, then a production canary\nat `canary_percent <= 25`, `assess_canary`, then `promote_canary` - see\n\"Deployment policy\". Do not begin the next service's production deploy until the\nprevious one is fully promoted.\n\n## Points model\n\nBalances live in an append-only ledger, mirroring the approach in \"Payments\nsettlement pipeline\": `earn`, `redeem`, `expire`, `adjust`. Balance is the sum,\nnever a stored counter. Redemption is authorized at `pricing_locked` and\ncommitted at `paid`; an abandoned cart releases the hold after 20 minutes.\n\nDefault rate is 1 point per whole currency unit, 100 points equals one currency\nunit of discount, points expire 12 months after earning. Maximum redemption is\n50% of order subtotal.\n\n## Risks\n\n- Double-redeem across concurrent sessions. Mitigated by the hold and by the\n  idempotency key on the checkout transition.\n- Accrual rule changes retroactively altering historical balances. The ledger\n  stamps the rate version at earn time.\n"

Removing the line does not\n   remove the secret.\n2. **Rotation was a deploy.** Rotating the processor key meant a PR, CI, staging,\n   canary, promote - per service. So rotation happened roughly never, and the\n   processor key in production had been unchanged for over a year.\n3. **No access audit.** We could not answer \"who read this value, and when\",\n   which is a direct finding in the annual audit.\n\nThe trigger was a scanner hit: a carrier token visible in a config file in a\nrepo that four teams could read.\n\n## Decision\n\nAll partner credentials move to the managed **secret manager**. Each service\nopts in with the config key **`use_secret_manager=true`** and references secrets\nby name rather than value. The application resolves secrets at startup and on a\nrefresh interval; the plaintext never appears in the repo, in a PR diff, or in a\ndeploy artifact.\n\nEvery credential moved is **rotated as part of the move**, on the assumption\nthat anything previously in the repo is compromised.\n\nRollout order: `payments` first (highest value), then `notifications`, then the\nremaining services.\n\n## Alternatives considered\n\n**Encrypted secrets committed to the repo (sealed values).** Rejected: it solves\nplaintext exposure but not rotation-as-a-deploy, and the decryption key becomes\nthe new committed secret.\n\n**Environment variables set manually on hosts.** Rejected: unauditable,\ndrift-prone, and impossible to reproduce.\n\n**Do nothing, tighten repo permissions.** Rejected: it does not address history,\nrotation, or audit.\n\n## Consequences\n\nPositive: rotation is an operation, not a release; access is logged per read;\nsecret scanning in CI becomes a hard gate rather than advisory.\n\nNegative: a new startup-time dependency. If the secret manager is unreachable a\nservice cannot start, so we cache the last successful resolution on disk,\nencrypted, with a short TTL, to survive a brief outage.\n\nOperational procedure for a leaked credential is in the \"Security response\"\nrunbook: move to the secret manager, **rotate**, deploy, verify, post to\n`#security`.\n"

The alias swap invalidated the entire query cache. Every in-flight query\nmissed simultaneously and hit the primary index, driving `latency_p99_ms` from\n~210ms to a peak of 2100ms and firing the `search latency_p99_ms` alert against\nits 300ms SLO. Search was slow, not down; conversion on search-originated\nsessions dropped an estimated 18% for the duration.\n\n## Timeline (UTC)\n\n- **14:02** Engineer starts a full index rebuild for an analyzer change. Routine;\n  done a dozen times before.\n- **14:41** Rebuild completes. Alias swaps to the new index. Query cache keys are\n  namespaced by index generation, so the swap invalidates 100% of the cache.\n- **14:42** `latency_p99_ms` crosses 300ms. Alert fires, `medium`.\n- **14:44** On-call acknowledges. Initial hypothesis: the new analyzer is slow.\n- **14:51** Index CPU is pegged; per-query cost is unchanged from before the\n  rebuild. Hypothesis discarded - it is volume, not per-query cost.\n- **14:58** Cache hit ratio confirmed at 3%, against a normal 76%. Root cause\n  identified.\n- **15:06** Traffic to search temporarily shed at the gateway by 30% to let the\n  cache refill.\n- **15:16** Hit ratio back above 60%; p99 at 340ms and falling.\n- **15:22** Shedding removed. p99 at 215ms.\n- **15:26** Alert resolved, incident resolved, update posted in `#incidents`.\n\n## Root cause\n\nThe query cache is namespaced by index generation. An alias swap therefore\nperforms a **complete, instantaneous cache flush** with no warm-up. Because the\ncache normally absorbs about **75% of index load**, the index was asked to serve\nroughly 4x its steady-state query volume within one second. Requests queued,\nlatency rose, clients retried, and the retries added load - a classic stampede\nwith a positive feedback loop.\n\n## Contributing factors\n\n- No warm-up step in the rebuild procedure. The runbook ended at \"swap alias\".\n- Rebuild was run at 14:00 local, in the daily traffic ramp, because the job\n  takes 40 minutes and nobody wanted to babysit it at night.\n- Single-flight coalescing existed for identical concurrent queries but the\n  stampede was across *thousands of distinct* queries, so coalescing did nothing.\n- No alert on cache hit ratio, so the actual signal was invisible for 14 minutes.\n\n## What went well\n\n- Alerting fired within a minute of the SLO breach.\n- Load shedding at the gateway was the correct blunt instrument and worked.\n\n## Action items\n\n1. Add a **warm-up phase** to the rebuild: replay the top 5000 queries against\n   the new index before swapping the alias. **Done.**\n2. Add **+/-10% TTL jitter** to `cache_ttl_s=300` so natural expiry never\n   synchronizes. **Done.**\n3. Alert on **cache hit ratio below 50%** for 5 minutes. **Done.**\n4. Move scheduled rebuilds to 03:00-05:00 UTC. **Done.**\n5. Document the stampede risk in the \"Search caching\" runbook. **Done.**\n"

The migration was applied to production before the\ndeploy, as policy requires - but the migration was **not backwards compatible**\nwith the code version already running. Between the migration completing and the\nnew version being fully rolled out, the running `v1.7.6` instances queried a\ncolumn that no longer existed. Product-detail and category pages returned 500s;\n`checkout` fell back to failing closed on pricing, per its design.\n\n## Timeline (UTC)\n\n- **09:12** `apply_migration(catalog, production, 0043)` starts.\n- **09:13** Migration completes. Column renamed.\n- **09:13** `v1.7.6` instances begin throwing\n  `UndefinedColumn: price_cents` on every pricing query.\n- **09:14** `catalog` error rate goes vertical. `checkout` starts failing closed.\n  Two alerts fire.\n- **09:15** Deploy of `v1.8.0` starts, as planned, but rolls instance by instance.\n- **09:17** On-call acknowledges, declares sev1.\n- **09:19** Commander recognizes the pattern: schema ahead of code, partial fleet.\n- **09:21** Decision: do **not** attempt to reverse the migration. Accelerate the\n  `v1.8.0` rollout instead.\n- **09:31** Rollout complete on all instances. Errors stop.\n- **09:34** Metrics confirmed recovered; alerts resolved; incident resolved.\n- **09:40** Update posted in `#incidents`; status page updated and cleared.\n- Later that day: `v1.8.0` was rolled back for an unrelated defect found in\n  review, which is when the second lesson landed - the rolled-back `v1.7.6` code\n  could not read the renamed column either, and a hotfix `v1.8.1` had to be cut\n  because **migrations are forward-only** and there was no going back.\n\n## Root cause\n\nA **destructive, non-backwards-compatible schema change shipped in one step**. A\ncolumn rename is two incompatible states with no overlap: code that knows the old\nname and code that knows the new name cannot both work against the same schema.\nAny window in which both code versions run - and a rolling deploy guarantees such\na window - is an outage.\n\n## Contributing factors\n\n- The \"migration before code\" rule was followed correctly, and following it\n  correctly was *insufficient*. The rule says nothing about compatibility with\n  the code already running.\n- The migration had one reviewer, from the authoring team.\n- Rolling deploys were assumed to be fast enough not to matter. They are not.\n- `catalog` is tier 2, so there was no canary to catch it at 25%.\n\n## What went well\n\n- Nobody tried to hand-write a reverse migration under pressure. Rolling forward\n  was the right call and it was made in six minutes.\n- `checkout` failing closed on pricing prevented selling at a wrong price.\n\n## Action items\n\n1. Write the **N-1 rule** into the \"Database migration policy\": every migration\n   must leave the schema usable by the currently deployed code. **Done.**\n2. Mandate the **expand/contract** pattern for renames: add column, dual-write,\n   backfill, switch reads, drop in a later migration. **Done.**\n3. Require a **second reviewer from platform** for migrations on tables above ten\n   million rows. **Done.**\n4. Add a CI check that flags `DROP COLUMN`, `RENAME COLUMN`, and new `NOT NULL`\n   constraints for explicit sign-off. **Done.**\n"

It is the whole workflow end to end; the runbooks it points at\nhave the detail.\n\n## The path\n\n**ticket - PR with structured changes - CI - merge - staging - canary - promote -\nverify - close**\n\n### 1. Ticket\n\nAll work starts from a ticket. It carries the type (`bug`, `feature`,\n`incident`, `security`, `postmortem`), the priority, and the owning service. If\nyou are doing work with no ticket, you are doing work nobody can find later.\n\n### 2. PR with structured changes\n\nA pull request is linked to its ticket and carries **structured changes**, not\njust prose. Change types:\n\n| Change type  | Use for                                        |\n| ------------ | ---------------------------------------------- |\n| `config`     | A config key and value in the service repo     |\n| `module`     | Adding or removing a code module               |\n| `dependency` | Upgrading a library (see \"Security response\")  |\n| `endpoint`   | Adding, deprecating, or retiring an endpoint   |\n| `flag`       | Defining a feature flag                        |\n| `test_fix`   | Fixing (`fix`) or quarantining a flaky test    |\n\nStructured changes are what make a PR mechanically checkable and what the deploy\ntooling reads. One concern per PR.\n\n### 3. CI\n\nCI runs four stages in order: **build - unit - integration - regression**. A\nfailing stage stops the run. Some checks are hard gates: retiring an endpoint\nthat still serves traffic fails CI, and so does a secret detected in the diff.\n\n### 4. Merge\n\nMerging cuts a version for the service. The version is the unit that gets\ndeployed; nothing reaches an environment except as a version.\n\n### 5. Staging\n\n`deploy_service(service, \"staging\", version)`. **Every production deploy must\nfirst succeed on staging with the same version** - see \"Deployment policy\". If\nthe change needs a schema migration, `apply_migration` runs against staging\n*before* this deploy - see \"Database migration policy\".\n\n### 6. Canary\n\nFor tier-1 services (`storefront-web`, `api-gateway`, `checkout`, `payments`),\nthe production deploy starts as a canary: `deploy_service` with\n`canary_percent <= 25`. Tier-2 services (`catalog`, `notifications`, `search`)\ndeploy at 100%.\n\n### 7. Promote\n\nRun `assess_canary`. Only when it reports **healthy** do you `promote_canary`.\nAn unhealthy canary is rolled back, not promoted.\n\n### 8. Verify\n\nRead the metric you were trying to move. Confirm it is inside its SLO. If an\nalert was firing, resolve it only after the metric has actually recovered.\n\n### 9. Close\n\nClose the ticket. If it was an incident, follow \"Incident response\" for the\nalert, incident, `#incidents` update, status page, and - for sev1 - the\npostmortem ticket.\n\n## Things new engineers get wrong\n\n- Enabling a feature flag before the guarded code is deployed. Deploy first, then\n  enable, at no more than 10%.\n- Skipping staging for \"a one-line config change\". There are no exceptions.\n- Promoting a canary because it \"looked fine\" instead of assessing it.\n- Resolving an alert before verifying recovery.\n- Quarantining a flaky test and closing the ticket. It does not close the ticket.\n\n## Where to look next\n\n\"Deployment policy\", \"Database migration policy\", \"Incident response\",\n\"Feature flags\", \"Retry and timeout standard\", \"Service catalog and service\ntiers\".\n"

Internal only - triage calmly.\n2. **Did something change?** Check recent deploys, canary promotions, feature\n   flag toggles, and config changes for the service and its dependencies, in that\n   order. The overwhelming majority of incidents follow a change within the last\n   hour.\n3. **Is it this service or a dependency?** A spike in `checkout` errors with a\n   simultaneous spike in `payments` latency is one incident, not two.

Severity follows blast radius: money path breaks are `critical`, degradation\n   is `high` or `medium`.\n\n## Instrumentation before traffic\n\nA service does not take production traffic until it emits both core metrics, has\nat least one SLO, and has a runbook entry naming its owner. This is checked at\nservice registration, not left to good intentions.\n\n## Dashboards\n\nEach service has one dashboard with a fixed top row: the two core metrics with\ntheir SLO lines drawn on them, deploy markers, and flag-change markers. Deploy\nand flag markers on the same timeline are the fastest correlation tool we have -\nmost incidents are diagnosed by seeing a metric step exactly at a marker.\n\n## Reviews\n\nSLOs are reviewed quarterly.

SLO: `latency_p99_ms < 250`.\n\n## Responsibilities\n\n1. **Routing** - map a public path to an internal service.\n2. **Authentication** - validate partner bearer tokens and storefront sessions;\n   reject unauthenticated requests before they reach any backend.\n3. **Rate limiting** - `rate_limit_rps` per partner token.\n4. **Traffic weighting** - split traffic between endpoint versions during a\n   migration.\n\nDeliberately *not* responsibilities: business logic, response transformation\nbeyond version adaptation, and caching. The gateway must stay boring, because\neverything is behind it.\n\n## Endpoint registry\n\nEndpoints live in the repo with a status: `active`, `deprecated`, or `retired`.\nStatus is a code change and ships through the normal PR-CI-deploy path. Current\npublic surface includes `/v1/orders`, `/v2/orders`, and `/v1/checkout`;\n`/internal/debug` exists and should not - it is unauthenticated and is being\nretired.\n\n## Traffic weights\n\nWeights are **production runtime state**, not repo config. Each endpoint carries\na weight from 0 to 100, and weights for a path family sum to 100. Changing a\nweight takes effect immediately without a deploy - the same property that makes\nfeature flags useful mitigation tools.\n\nWeight changes move in steps of **at most 50 percentage points**, and an\nendpoint may only be retired at 0% - both enforced per the \"API deprecation\"\nrunbook, the second one as a hard CI gate.\n\n## Rate limiting\n\n`rate_limit_rps=500` per partner token by default, token-bucket with a 2x burst\nallowance. Over-limit requests get `429` with `Retry-After`. Limits are per token\nand not per IP; partners behind a NAT would otherwise share a bucket. Storefront\nsession traffic uses a separate, looser bucket keyed by session.\n\n## Connection pooling\n\nThe gateway holds an upstream connection pool per backend service. This is the\nmost performance-sensitive component in the fleet and the source of our worst\nrecent incident: a connection-pool rewrite in `v5.1.0` leaked a goroutine per\nrequest, and p99 went from ~120ms to ~1030ms - 4x the 250ms SLO. The defect is\npresent in `v5.1.0` and in anything cut on top of it; recovery required a\nrollback to `v5.0.9`. See \"Rollback and recovery\".\n\nUpstream calls follow the \"Retry and timeout standard\": three attempts, timeout\nat or below 2000ms.\n\n## Deployment\n\nTier 1: staging first, production canary at `canary_percent <= 25`,\n`assess_canary`, then `promote_canary`. Because every request in the company\npasses through this service, canary discipline here is not negotiable.\n\n## Open questions\n\n- Per-endpoint rate limits, not just per-token.\n- Move token validation to an edge cache to shave ~8ms off p50.\n"

Tier is a property of blast\nradius, not of team seniority or code quality.\n\n## Dependency shape\n\n```\nstorefront-web -> api-gateway -> checkout -> payments -> notifications\n                              -> search   -> catalog\n                                 catalog  <- checkout (pricing)\n```\n\nRead it as: a failure in `catalog` shows up as a `checkout` and `search`\nproblem, and a failure in `notifications` should show up nowhere at all, because\ncallers treat it as best-effort. When it does show up in `payments`, that is a\nretry and timeout misconfiguration, not a `notifications` outage - see \"Retry\nand timeout standard\".\n\n## Environments\n\nTwo: `staging` and `production`. Staging carries a sampled copy of production\ncatalog data and synthetic orders. It is not a traffic-realistic environment,\nwhich is exactly why tier-1 services canary in production - see \"ADR-021:\nStandardize on staged canary deploys\".\n\n## Channels\n\n- `#incidents` - incident coordination and status updates.\n- `#security` - advisories and audit notes, CVE ids referenced literally.\n- `#eng` - everything else.\n\n## Adding a service\n\nRegister it with a team, a tier, an owner, both core metrics, at least one SLO,\nand a runbook entry before it takes traffic. See \"Observability, SLOs, and\nalerting\".\n"

+    "body": "# Queue consumer tuning\n\nOwner: platform. Primary consumer service: `notifications` (tier 2), which\ndrains the email, SMS, and push delivery queues. The same rules apply to any\nservice that consumes from the message broker.\n\n## The rule\n\n`prefetch_count` must be a **bounded** value. **Recommended: 50.**\n\n`prefetch_count=0` means **unlimited prefetch** and is the single worst setting\nin this runbook.\n\n## What prefetch does\n\nPrefetch is the number of unacknowledged messages the broker will push to a\nsingle consumer. With `prefetch_count=50`, a consumer holds at most 50\nin-flight messages; the broker will not send a 51st until one is acknowledged.\nThis is the backpressure mechanism - it is what lets a slow consumer tell the\nbroker to slow down.\n\nWith `prefetch_count=0` there is no backpressure. The broker pushes the entire\nbacklog to whichever consumer connects first. Consequences, all of which we have\nseen in `notifications`:\n\n- **Memory pressure.** A 400k-message backlog lands in one process's heap. RSS\n  climbs until the container hits its memory limit.\n- **Consumer restarts.** The container is OOM-killed, the unacknowledged\n  messages are redelivered, the restarted consumer grabs them all again, and it\n  is killed again. A restart loop that looks like a broker problem and is not.\n- **Terrible load distribution.** One consumer holds everything while its\n  siblings sit idle, so scaling out does nothing.\n- **Head-of-line latency.** A high-priority message sits behind 400k others.\n\n## Sizing\n\n| Message profile                | prefetch_count |\n| ------------------------------ | -------------- |\n| Fast, uniform (a few ms each)  | 100-200        |\n| Standard delivery work         | **50**         |\n| Slow or variable (seconds)     | 5-10           |\n| Long-running jobs (minutes)    | 1              |\n\nRule of thumb: `prefetch_count` should be roughly the number of messages a\nconsumer can process in one to two seconds. Start at 50 and adjust with\nevidence.\n\n## Related settings\n\n- `smtp_pool` on `notifications` bounds concurrent SMTP connections. Prefetch\n  above the SMTP concurrency just buys queueing inside the process.\n- Ack **after** the work is done, never on receipt. Acking on receipt turns a\n  crash into silent message loss.\n- Dead-letter after 5 delivery attempts so a poison message cannot loop forever.\n\n## Changing it\n\nRepo config: PR with a `config` change, CI, merge, staging, production.\n`notifications` is tier 2 - straight 100% deploy after staging. Watch consumer\nmemory and queue depth for one full peak after the change.\n"

+    "body": "# Checkout architecture\n\nService: `checkout` (tier 1, python, commerce). Owns the cart and the checkout\norchestration state machine. SLOs: `error_rate_pct < 1.0`,\n`latency_p99_ms < 400`.\n\n## Responsibilities\n\n`checkout` owns the transition from \"a cart exists\" to \"an order exists and is\npaid\". It does not own money movement (that is `payments`), product data (that\nis `catalog`), or customer notification (that is `notifications`). It owns the\nsequencing and the guarantee that the sequence happens exactly once.\n\nModules: `cart`, `checkout_flow`, and - once the loyalty program ships -\n`loyalty_redeem`.\n\n## The state machine\n\nEvery checkout session is a row with an explicit state:\n\n```\ncart_open -> pricing_locked -> payment_pending -> paid -> order_created\n                   |                   |\n                   +-> abandoned       +-> payment_failed\n```\n\nTransitions are append-only and each is stamped with the idempotency key of the\nrequest that caused it. Replaying a request that has already produced a\ntransition returns the existing result rather than performing it again. This is\nwhat makes the checkout endpoint safe to retry, which matters because clients\nretry aggressively on mobile networks.\n\n## Dependencies\n\n| Downstream      | Call                     | Timeout budget            |\n| --------------- | ------------------------ | ------------------------- |\n| `catalog`       | price and availability   | `<= 2000ms`, 3 attempts   |\n| `payments`      | authorize and capture    | `payment_timeout_ms`      |\n| `notifications` | order confirmation       | async, fire-and-forget    |\n\nAll synchronous calls follow the \"Retry and timeout standard\": three attempts,\ntimeout at or below 2000ms. The `notifications` call is deliberately\nasynchronous - a confirmation email must never be able to fail an order.\n\n## Pricing lock\n\nAt `pricing_locked` we snapshot the price, the promotion, and the tax\ncomputation into the session row. From that point the customer pays the price\nthey were shown even if `catalog` changes underneath. The lock expires after 20\nminutes, after which the session re-prices.\n\n## Failure handling\n\n- `payments` timeout: the session stays `payment_pending` and a reconciliation\n  job asks `payments` for the authoritative status. We never assume a timeout\n  means \"did not happen\".\n- `catalog` unavailable: fail closed. We do not sell at a guessed price.\n- Partial capture: not supported; a capture is all-or-nothing per order.\n\n## Feature flags\n\nCheckout-adjacent behavior ships behind flags - `instant_refunds`,\n`express_checkout`. Per the \"Feature flags\" runbook, the code deploys first and\nthe flag is enabled afterwards at no more than 10%. `instant_refunds` is the\ncautionary tale: ramped to 100% in production, it took `error_rate_pct` from\n0.3% to 5.5% via a nil-pointer panic in the refund worker.\n\n## Open questions\n\n- Should the pricing lock move into `catalog` so `search` can honor it too?\n- Cart merge on login is still last-write-wins; it should be a real merge.\n"

There is no shared\nlibrary; the contract between them is the points-rate field on the product\npayload and the redeem call on the checkout API.\n\n## Why this split\n\nAccrual rules are product data - they vary per product and per category, they\nchange with merchandising campaigns, and they belong next to pricing. Redemption\nis an order-level money decision and belongs in the checkout state machine.\nDisplay is display. Putting accrual in `checkout` would have meant `checkout`\nreading the product rules table, which is exactly the coupling we spent last\nyear removing.\n\n## Rollout order\n\nDeployment order matters and is not negotiable:\n\n**`catalog` - then `checkout` - then `storefront-web`.**\n\nThe reasoning is a strict data dependency chain:\n\n1. `catalog` must be emitting a points rate on the product payload before\n   `checkout` can compute a balance to redeem against. If `checkout` ships\n   first, every redeem attempt reads a missing field and either errors or\n   silently computes zero.\n2. `checkout` must expose the redeem endpoint and be live before\n   `storefront-web` renders a redeem button. If the widget ships first,\n   customers see a button that 404s - a visible, embarrassing failure on the\n   busiest page we have.\n\n`catalog` is tier 2 (straight production deploy after staging). `checkout` and\n`storefront-web` are tier 1, so each is staging-first, then a production canary\nat `canary_percent <= 25`, `assess_canary`, then `promote_canary` - see\n\"Deployment policy\". Do not begin the next service's production deploy until the\nprevious one is fully promoted.\n\n## Points model\n\nBalances live in an append-only ledger, mirroring the approach in \"Payments\nsettlement pipeline\": `earn`, `redeem`, `expire`, `adjust`. Balance is the sum,\nnever a stored counter. Redemption is authorized at `pricing_locked` and\ncommitted at `paid`; an abandoned cart releases the hold after 20 minutes.\n\nDefault rate is 1 point per whole currency unit, 100 points equals one currency\nunit of discount, points expire 12 months after earning. Maximum redemption is\n50% of order subtotal.\n\n## Risks\n\n- Double-redeem across concurrent sessions. Mitigated by the hold and by the\n  idempotency key on the checkout transition.\n- Accrual rule changes retroactively altering historical balances. The ledger\n  stamps the rate version at earn time.\n"

The alias swap invalidated the entire query cache. Every in-flight query\nmissed simultaneously and hit the primary index, driving `latency_p99_ms` from\n~210ms to a peak of 2100ms and firing the `search latency_p99_ms` alert against\nits 300ms SLO. Search was slow, not down; conversion on search-originated\nsessions dropped an estimated 18% for the duration.\n\n## Timeline (UTC)\n\n- **14:02** Engineer starts a full index rebuild for an analyzer change. Routine;\n  done a dozen times before.\n- **14:41** Rebuild completes. Alias swaps to the new index. Query cache keys are\n  namespaced by index generation, so the swap invalidates 100% of the cache.\n- **14:42** `latency_p99_ms` crosses 300ms. Alert fires, `medium`.\n- **14:44** On-call acknowledges. Initial hypothesis: the new analyzer is slow.\n- **14:51** Index CPU is pegged; per-query cost is unchanged from before the\n  rebuild. Hypothesis discarded - it is volume, not per-query cost.\n- **14:58** Cache hit ratio confirmed at 3%, against a normal 76%. Root cause\n  identified.\n- **15:06** Traffic to search temporarily shed at the gateway by 30% to let the\n  cache refill.\n- **15:16** Hit ratio back above 60%; p99 at 340ms and falling.\n- **15:22** Shedding removed. p99 at 215ms.\n- **15:26** Alert resolved, incident resolved, update posted in `#incidents`.\n\n## Root cause\n\nThe query cache is namespaced by index generation. An alias swap therefore\nperforms a **complete, instantaneous cache flush** with no warm-up. Because the\ncache normally absorbs about **75% of index load**, the index was asked to serve\nroughly 4x its steady-state query volume within one second. Requests queued,\nlatency rose, clients retried, and the retries added load - a classic stampede\nwith a positive feedback loop.\n\n## Contributing factors\n\n- No warm-up step in the rebuild procedure. The runbook ended at \"swap alias\".\n- Rebuild was run at 14:00 local, in the daily traffic ramp, because the job\n  takes 40 minutes and nobody wanted to babysit it at night.\n- Single-flight coalescing existed for identical concurrent queries but the\n  stampede was across *thousands of distinct* queries, so coalescing did nothing.\n- No alert on cache hit ratio, so the actual signal was invisible for 14 minutes.\n\n## What went well\n\n- Alerting fired within a minute of the SLO breach.\n- Load shedding at the gateway was the correct blunt instrument and worked.\n\n## Action items\n\n1. Add a **warm-up phase** to the rebuild: replay the top 5000 queries against\n   the new index before swapping the alias. **Done.**\n2. Add **+/-10% TTL jitter** to `cache_ttl_s=300` so natural expiry never\n   synchronizes. **Done.**\n3. Alert on **cache hit ratio below 50%** for 5 minutes. **Done.**\n4. Move scheduled rebuilds to 03:00-05:00 UTC. **Done.**\n5. Document the stampede risk in the \"Search caching\" runbook. **Done.**\n"

The migration was applied to production before the\ndeploy, as policy requires - but the migration was **not backwards compatible**\nwith the code version already running. Between the migration completing and the\nnew version being fully rolled out, the running `v1.7.6` instances queried a\ncolumn that no longer existed. Product-detail and category pages returned 500s;\n`checkout` fell back to failing closed on pricing, per its design.\n\n## Timeline (UTC)\n\n- **09:12** `apply_migration(catalog, production, 0043)` starts.\n- **09:13** Migration completes. Column renamed.\n- **09:13** `v1.7.6` instances begin throwing\n  `UndefinedColumn: price_cents` on every pricing query.\n- **09:14** `catalog` error rate goes vertical. `checkout` starts failing closed.\n  Two alerts fire.\n- **09:15** Deploy of `v1.8.0` starts, as planned, but rolls instance by instance.\n- **09:17** On-call acknowledges, declares sev1.\n- **09:19** Commander recognizes the pattern: schema ahead of code, partial fleet.\n- **09:21** Decision: do **not** attempt to reverse the migration. Accelerate the\n  `v1.8.0` rollout instead.\n- **09:31** Rollout complete on all instances. Errors stop.\n- **09:34** Metrics confirmed recovered; alerts resolved; incident resolved.\n- **09:40** Update posted in `#incidents`; status page updated and cleared.\n- Later that day: `v1.8.0` was rolled back for an unrelated defect found in\n  review, which is when the second lesson landed - the rolled-back `v1.7.6` code\n  could not read the renamed column either, and a hotfix `v1.8.1` had to be cut\n  because **migrations are forward-only** and there was no going back.\n\n## Root cause\n\nA **destructive, non-backwards-compatible schema change shipped in one step**. A\ncolumn rename is two incompatible states with no overlap: code that knows the old\nname and code that knows the new name cannot both work against the same schema.\nAny window in which both code versions run - and a rolling deploy guarantees such\na window - is an outage.\n\n## Contributing factors\n\n- The \"migration before code\" rule was followed correctly, and following it\n  correctly was *insufficient*. The rule says nothing about compatibility with\n  the code already running.\n- The migration had one reviewer, from the authoring team.\n- Rolling deploys were assumed to be fast enough not to matter. They are not.\n- `catalog` is tier 2, so there was no canary to catch it at 25%.\n\n## What went well\n\n- Nobody tried to hand-write a reverse migration under pressure. Rolling forward\n  was the right call and it was made in six minutes.\n- `checkout` failing closed on pricing prevented selling at a wrong price.\n\n## Action items\n\n1. Write the **N-1 rule** into the \"Database migration policy\": every migration\n   must leave the schema usable by the currently deployed code. **Done.**\n2. Mandate the **expand/contract** pattern for renames: add column, dual-write,\n   backfill, switch reads, drop in a later migration. **Done.**\n3. Require a **second reviewer from platform** for migrations on tables above ten\n   million rows. **Done.**\n4. Add a CI check that flags `DROP COLUMN`, `RENAME COLUMN`, and new `NOT NULL`\n   constraints for explicit sign-off. **Done.**\n"

+    "service": "notifications",
+    "author": "Priya Nair",
+    "day": 226,
+    "body": "# Queue consumer tuning\n\nOwner: platform. Primary consumer service: `notifications` (tier 2), which\ndrains the email, SMS, and push delivery queues. The same rules apply to any\nservice that consumes from the message broker.\n\n## The rule\n\n`prefetch_count` must be a **bounded** value. **Recommended: 50.**\n\n`prefetch_count=0` means **unlimited prefetch** and is the single worst setting\nin this runbook.\n\n## What prefetch does\n\nPrefetch is the number of unacknowledged messages the broker will push to a\nsingle consumer. With `prefetch_count=50`, a consumer holds at most 50\nin-flight messages; the broker will not send a 51st until one is acknowledged.\nThis is the backpressure mechanism - it is what lets a slow consumer tell the\nbroker to slow down.\n\nWith `prefetch_count=0` there is no backpressure. The broker pushes the entire\nbacklog to whichever consumer connects first. Consequences, all of which we have\nseen in `notifications`:\n\n- **Memory pressure.** A 400k-message backlog lands in one process's heap. RSS\n  climbs until the container hits its memory limit.\n- **Consumer restarts.** The container is OOM-killed, the unacknowledged\n  messages are redelivered, the restarted consumer grabs them all again, and it\n  is killed again. A restart loop that looks like a broker problem and is not.\n- **Terrible load distribution.** One consumer holds everything while its\n  siblings sit idle, so scaling out does nothing.\n- **Head-of-line latency.** A high-priority message sits behind 400k others.\n\n## Sizing\n\n| Message profile                | prefetch_count |\n| ------------------------------ | -------------- |\n| Fast, uniform (a few ms each)  | 100-200        |\n| Standard delivery work         | **50**         |\n| Slow or variable (seconds)     | 5-10           |\n| Long-running jobs (minutes)    | 1              |\n\nRule of thumb: `prefetch_count` should be roughly the number of messages a\nconsumer can process in one to two seconds. Start at 50 and adjust with\nevidence.\n\n## Related settings\n\n- `smtp_pool` on `notifications` bounds concurrent SMTP connections. Prefetch\n  above the SMTP concurrency just buys queueing inside the process.\n- Ack **after** the work is done, never on receipt. Acking on receipt turns a\n  crash into silent message loss.\n- Dead-letter after 5 delivery attempts so a poison message cannot loop forever.\n\n## Changing it\n\nRepo config: PR with a `config` change, CI, merge, staging, production.\n`notifications` is tier 2 - straight 100% deploy after staging. Watch consumer\nmemory and queue depth for one full peak after the change.\n"

SLOs: `error_rate_pct < 1.0`,\n`latency_p99_ms < 400`.\n\n## Responsibilities\n\n`checkout` owns the transition from \"a cart exists\" to \"an order exists and is\npaid\". It does not own money movement (that is `payments`), product data (that\nis `catalog`), or customer notification (that is `notifications`). It owns the\nsequencing and the guarantee that the sequence happens exactly once.\n\nModules: `cart`, `checkout_flow`, and - once the loyalty program ships -\n`loyalty_redeem`.\n\n## The state machine\n\nEvery checkout session is a row with an explicit state:\n\n```\ncart_open -> pricing_locked -> payment_pending -> paid -> order_created\n                   |                   |\n                   +-> abandoned       +-> payment_failed\n```\n\nTransitions are append-only and each is stamped with the idempotency key of the\nrequest that caused it. Replaying a request that has already produced a\ntransition returns the existing result rather than performing it again. This is\nwhat makes the checkout endpoint safe to retry, which matters because clients\nretry aggressively on mobile networks.\n\n## Dependencies\n\n| Downstream      | Call                     | Timeout budget            |\n| --------------- | ------------------------ | ------------------------- |\n| `catalog`       | price and availability   | `<= 2000ms`, 3 attempts   |\n| `payments`      | authorize and capture    | `payment_timeout_ms`      |\n| `notifications` | order confirmation       | async, fire-and-forget    |\n\nAll synchronous calls follow the \"Retry and timeout standard\": three attempts,\ntimeout at or below 2000ms. The `notifications` call is deliberately\nasynchronous - a confirmation email must never be able to fail an order.\n\n## Pricing lock\n\nAt `pricing_locked` we snapshot the price, the promotion, and the tax\ncomputation into the session row. From that point the customer pays the price\nthey were shown even if `catalog` changes underneath. The lock expires after 20\nminutes, after which the session re-prices.\n\n## Failure handling\n\n- `payments` timeout: the session stays `payment_pending` and a reconciliation\n  job asks `payments` for the authoritative status. We never assume a timeout\n  means \"did not happen\".\n- `catalog` unavailable: fail closed. We do not sell at a guessed price.\n- Partial capture: not supported; a capture is all-or-nothing per order.\n\n## Feature flags\n\nCheckout-adjacent behavior ships behind flags - `instant_refunds`,\n`express_checkout`. Per the \"Feature flags\" runbook, the code deploys first and\nthe flag is enabled afterwards at no more than 10%. `instant_refunds` is the\ncautionary tale: ramped to 100% in production, it took `error_rate_pct` from\n0.3% to 5.5% via a nil-pointer panic in the refund worker.\n\n## Open questions\n\n- Should the pricing lock move into `catalog` so `search` can honor it too?\n- Cart merge on login is still last-write-wins; it should be a real merge.\n"

There is no shared\nlibrary; the contract between them is the points-rate field on the product\npayload and the redeem call on the checkout API.\n\n## Why this split\n\nAccrual rules are product data - they vary per product and per category, they\nchange with merchandising campaigns, and they belong next to pricing. Redemption\nis an order-level money decision and belongs in the checkout state machine.\nDisplay is display. Putting accrual in `checkout` would have meant `checkout`\nreading the product rules table, which is exactly the coupling we spent last\nyear removing.\n\n## Rollout order\n\nDeployment order matters and is not negotiable:\n\n**`catalog` - then `checkout` - then `storefront-web`.**\n\nThe reasoning is a strict data dependency chain:\n\n1. `catalog` must be emitting a points rate on the product payload before\n   `checkout` can compute a balance to redeem against. If `checkout` ships\n   first, every redeem attempt reads a missing field and either errors or\n   silently computes zero.\n2. `checkout` must expose the redeem endpoint and be live before\n   `storefront-web` renders a redeem button. If the widget ships first,\n   customers see a button that 404s - a visible, embarrassing failure on the\n   busiest page we have.\n\n`catalog` is tier 2 (straight production deploy after staging). `checkout` and\n`storefront-web` are tier 1, so each is staging-first, then a production canary\nat `canary_percent <= 25`, `assess_canary`, then `promote_canary` - see\n\"Deployment policy\". Do not begin the next service's production deploy until the\nprevious one is fully promoted.\n\n## Points model\n\nBalances live in an append-only ledger, mirroring the approach in \"Payments\nsettlement pipeline\": `earn`, `redeem`, `expire`, `adjust`. Balance is the sum,\nnever a stored counter. Redemption is authorized at `pricing_locked` and\ncommitted at `paid`; an abandoned cart releases the hold after 20 minutes.\n\nDefault rate is 1 point per whole currency unit, 100 points equals one currency\nunit of discount, points expire 12 months after earning. Maximum redemption is\n50% of order subtotal.\n\n## Risks\n\n- Double-redeem across concurrent sessions. Mitigated by the hold and by the\n  idempotency key on the checkout transition.\n- Accrual rule changes retroactively altering historical balances. The ledger\n  stamps the rate version at earn time.\n"

The alias swap invalidated the entire query cache. Every in-flight query\nmissed simultaneously and hit the primary index, driving `latency_p99_ms` from\n~210ms to a peak of 2100ms and firing the `search latency_p99_ms` alert against\nits 300ms SLO. Search was slow, not down; conversion on search-originated\nsessions dropped an estimated 18% for the duration.\n\n## Timeline (UTC)\n\n- **14:02** Engineer starts a full index rebuild for an analyzer change. Routine;\n  done a dozen times before.\n- **14:41** Rebuild completes. Alias swaps to the new index. Query cache keys are\n  namespaced by index generation, so the swap invalidates 100% of the cache.\n- **14:42** `latency_p99_ms` crosses 300ms. Alert fires, `medium`.\n- **14:44** On-call acknowledges. Initial hypothesis: the new analyzer is slow.\n- **14:51** Index CPU is pegged; per-query cost is unchanged from before the\n  rebuild. Hypothesis discarded - it is volume, not per-query cost.\n- **14:58** Cache hit ratio confirmed at 3%, against a normal 76%. Root cause\n  identified.\n- **15:06** Traffic to search temporarily shed at the gateway by 30% to let the\n  cache refill.\n- **15:16** Hit ratio back above 60%; p99 at 340ms and falling.\n- **15:22** Shedding removed. p99 at 215ms.\n- **15:26** Alert resolved, incident resolved, update posted in `#incidents`.\n\n## Root cause\n\nThe query cache is namespaced by index generation. An alias swap therefore\nperforms a **complete, instantaneous cache flush** with no warm-up. Because the\ncache normally absorbs about **75% of index load**, the index was asked to serve\nroughly 4x its steady-state query volume within one second. Requests queued,\nlatency rose, clients retried, and the retries added load - a classic stampede\nwith a positive feedback loop.\n\n## Contributing factors\n\n- No warm-up step in the rebuild procedure. The runbook ended at \"swap alias\".\n- Rebuild was run at 14:00 local, in the daily traffic ramp, because the job\n  takes 40 minutes and nobody wanted to babysit it at night.\n- Single-flight coalescing existed for identical concurrent queries but the\n  stampede was across *thousands of distinct* queries, so coalescing did nothing.\n- No alert on cache hit ratio, so the actual signal was invisible for 14 minutes.\n\n## What went well\n\n- Alerting fired within a minute of the SLO breach.\n- Load shedding at the gateway was the correct blunt instrument and worked.\n\n## Action items\n\n1. Add a **warm-up phase** to the rebuild: replay the top 5000 queries against\n   the new index before swapping the alias. **Done.**\n2. Add **+/-10% TTL jitter** to `cache_ttl_s=300` so natural expiry never\n   synchronizes. **Done.**\n3. Alert on **cache hit ratio below 50%** for 5 minutes. **Done.**\n4. Move scheduled rebuilds to 03:00-05:00 UTC. **Done.**\n5. Document the stampede risk in the \"Search caching\" runbook. **Done.**\n"

The migration was applied to production before the\ndeploy, as policy requires - but the migration was **not backwards compatible**\nwith the code version already running. Between the migration completing and the\nnew version being fully rolled out, the running `v1.7.6` instances queried a\ncolumn that no longer existed. Product-detail and category pages returned 500s;\n`checkout` fell back to failing closed on pricing, per its design.\n\n## Timeline (UTC)\n\n- **09:12** `apply_migration(catalog, production, 0043)` starts.\n- **09:13** Migration completes. Column renamed.\n- **09:13** `v1.7.6` instances begin throwing\n  `UndefinedColumn: price_cents` on every pricing query.\n- **09:14** `catalog` error rate goes vertical. `checkout` starts failing closed.\n  Two alerts fire.\n- **09:15** Deploy of `v1.8.0` starts, as planned, but rolls instance by instance.\n- **09:17** On-call acknowledges, declares sev1.\n- **09:19** Commander recognizes the pattern: schema ahead of code, partial fleet.\n- **09:21** Decision: do **not** attempt to reverse the migration. Accelerate the\n  `v1.8.0` rollout instead.\n- **09:31** Rollout complete on all instances. Errors stop.\n- **09:34** Metrics confirmed recovered; alerts resolved; incident resolved.\n- **09:40** Update posted in `#incidents`; status page updated and cleared.\n- Later that day: `v1.8.0` was rolled back for an unrelated defect found in\n  review, which is when the second lesson landed - the rolled-back `v1.7.6` code\n  could not read the renamed column either, and a hotfix `v1.8.1` had to be cut\n  because **migrations are forward-only** and there was no going back.\n\n## Root cause\n\nA **destructive, non-backwards-compatible schema change shipped in one step**. A\ncolumn rename is two incompatible states with no overlap: code that knows the old\nname and code that knows the new name cannot both work against the same schema.\nAny window in which both code versions run - and a rolling deploy guarantees such\na window - is an outage.\n\n## Contributing factors\n\n- The \"migration before code\" rule was followed correctly, and following it\n  correctly was *insufficient*. The rule says nothing about compatibility with\n  the code already running.\n- The migration had one reviewer, from the authoring team.\n- Rolling deploys were assumed to be fast enough not to matter. They are not.\n- `catalog` is tier 2, so there was no canary to catch it at 25%.\n\n## What went well\n\n- Nobody tried to hand-write a reverse migration under pressure. Rolling forward\n  was the right call and it was made in six minutes.\n- `checkout` failing closed on pricing prevented selling at a wrong price.\n\n## Action items\n\n1. Write the **N-1 rule** into the \"Database migration policy\": every migration\n   must leave the schema usable by the currently deployed code. **Done.**\n2. Mandate the **expand/contract** pattern for renames: add column, dual-write,\n   backfill, switch reads, drop in a later migration. **Done.**\n3. Require a **second reviewer from platform** for migrations on tables above ten\n   million rows. **Done.**\n4. Add a CI check that flags `DROP COLUMN`, `RENAME COLUMN`, and new `NOT NULL`\n   constraints for explicit sign-off. **Done.**\n"
