+Customer support escalated a morning reliability review after two dashboards disagreed. Keep this to an investigation; production should remain unchanged. OPS-163 — Root cause: analytics connections are refused, not slow Get to the bottom of analytics-connection-refused: not just which service, but the mechanism and the exact setting responsible. The service's own code is not necessarily where this lives — confirm it against the state of the system rather than inferring it from the symptom alone. Leave an audit-ready diagnosis for 'analytics-connection-refused' that names the responsible service, the fault type, the offending key, and your evidence. The work item is DOB-001 for analytics-worker. Its business boundary is reporting freshness, warehouse replica access, scheduled rollups, and downstream decision data. The disputed mechanism is outbound connectivity, DNS reachability, firewall policy, and dependency access. Reconcile current authority with live state, make only supported changes, and leave a case-room handoff that you have reopened and verified.

-    "body": "# Search caching\n\nOwner: growth. Service: `search` (tier 2, python). SLO:\n`latency_p99_ms < 300`.\n\n## The rule\n\nProduction `search` **requires `cache_enabled=true`**. This is not a tuning\nknob; it is a capacity assumption baked into how the index cluster is sized.\n\n## Why\n\nThe query cache sits in front of the primary index and absorbs roughly **75% of\nindex load**. Search traffic is extremely head-heavy: the top few thousand\nqueries (\"black jeans\", \"usb-c cable\", \"gift card\") are a large majority of all\nrequests, and their result sets change only when the index is rebuilt. Serving\nthose from cache is close to free.\n\nWith `cache_enabled=false` every request goes to the primary index. Observed\neffect in production: `latency_p99_ms` moves from a ~210ms baseline to ~640ms and\nkeeps climbing as concurrency rises, blowing through the 300ms SLO and firing a\n`medium` alert. The service does not error - it just gets slow, which is why this\none is easy to miss until the alert fires. The tell in the logs is:\n\n```\nWARN query cache disabled (cache_enabled=false); every request is hitting the primary index\n```\n\n## Config keys\n\n| Key             | Production value | Notes                                      |\n| --------------- | ---------------- | ------------------------------------------ |\n| `cache_enabled` | `true`           | Required. Never ship `false` to production. |\n| `cache_ttl_s`   | `300`            | Standard TTL. Five minutes.                 |\n| `index_shards`  | `4`              | Change only with a capacity review.         |\n\n`cache_ttl_s=300` is the standard. It is a deliberate compromise: long enough\nthat the hit rate stays above 70%, short enough that a price or availability\nchange is visible within five minutes. Do not lower it below 60 - at that point\nthe stampede risk (below) outweighs the freshness gain. Do not raise it above\n900 without merchandising sign-off, because stale out-of-stock results generate\nsupport tickets.\n\n## Cache stampede\n\nA cold cache is dangerous, not merely slow. When many identical queries miss at\nonce they all reach the index simultaneously. We ship single-flight coalescing\nplus a +/-10% TTL jitter for exactly this reason. If you flush the cache\nmanually, do it during low traffic and expect a latency spike. The full story is\nin \"Postmortem: search cache stampede after index rebuild\".\n\n## Changing cache config\n\n`cache_enabled` and `cache_ttl_s` are repo config, not runtime flags. Changing\nthem means a PR with a `config` change, CI, merge, then a deploy - staging\nfirst, per the \"Deployment policy\". `search` is tier 2, so production deploys go\nstraight to 100%.\n\n## Verification\n\nAfter deploying, confirm `latency_p99_ms` has returned to the ~210ms band before\nresolving any related alert.\n"

-    "body": "# Catalog pricing performance\n\nOwner: commerce. Service: `catalog` (tier 2, python). Consumed by `search`,\n`checkout`, and `storefront-web` on every product listing render.\n\n## The rule\n\n`batch_pricing_enabled=true` is **required in production**.\n\n## Why\n\n`catalog` resolves a price per product from the pricing rules table, applying\nthe active promotion, the customer's currency, and any tier discount. With\n`batch_pricing_enabled=false`, the listing endpoint loops over the products in\nthe response and issues one pricing query per product. This is a textbook\n**N+1 pattern**: a 48-item category page produces 1 listing query plus 48\npricing queries.\n\nMeasured cost: the per-product loop adds roughly **500ms at p99** on a standard\ncategory page. It also multiplies database connection checkouts by the page\nsize, which is how a catalog slowdown turns into a `db_pool_size` exhaustion\nevent in a service that was nowhere near its own limits (see \"Connection pool\nsizing\").\n\nWith `batch_pricing_enabled=true` the same page issues one listing query and one\nbatched pricing query with an `IN` clause over the product ids, then applies\npromotions in memory. Same results, two round trips.\n\n## Config keys\n\n| Key                       | Production value | Notes                                  |\n| ------------------------- | ---------------- | -------------------------------------- |\n| `batch_pricing_enabled`   | `true`           | Required. The N+1 killer.              |\n| `cdn_enabled`             | `true`           | See \"CDN and media delivery\".          |\n\n## How to spot it\n\n- p99 on `catalog` listing endpoints scales with page size rather than staying\n  flat. If 24 items is 200ms and 96 items is 900ms, it is the loop.\n- Database query counts per request in the hundreds.\n- Log lines of the form `pricing lookup for product_id=... (batch disabled)`\n  repeating with the same trace id.\n\n## Fixing it\n\n`batch_pricing_enabled` is repo config. Ship it as a PR with a `config` change,\nrun CI, merge, deploy to staging, then production. `catalog` is tier 2 so the\nproduction deploy is a straight 100% deploy - no canary required, though a\ncanary is never wrong.\n\nAfter the deploy, re-measure p99 on a large category page before closing the\nticket.\n\n## Do not\n\n- Do not \"fix\" this by raising `db_pool_size`. That hides the symptom and moves\n  the failure to the database.\n- Do not add a per-product cache in front of the loop. The batch query is\n  cheaper than the cache lookups it would replace.\n"

-    "body": "# Feature flags\n\nEvery new user-facing feature ships **dark**: merged, deployed, and switched\noff, then turned on gradually.\n\n## Defining a flag\n\nA flag is defined by a `flag` change in the PR that introduces the guarded code.\nFlag and code land together, in one PR, so there is never a flag referencing\ncode that does not exist or guarded code with no way to turn it off. At merge\nthe flag is created **disabled in both environments** with a rollout of 0%.\n\nNaming: lowercase snake_case, describing the feature, not the experiment -\n`express_checkout`, `instant_refunds`, `new_search_ui`. Not `mei_test_2` and not\n`enable_new_thing_v3_final`.\n\n## Ordering: deploy the code, then enable the flag\n\n**The guarded code must be deployed to production BEFORE the flag is enabled\nthere.** Enabling a flag whose code is not deployed does one of two things:\nnothing at all (best case, and you waste an hour wondering why), or it activates\na half-present code path across a partially deployed fleet (worst case).\n\nSo the sequence is:\n\n1. PR with the module change and the `flag` change - CI - merge.\n2. Deploy to staging.\n3. Deploy to production. Tier-1 services canary at `canary_percent <= 25`,\n   `assess_canary`, then `promote_canary` (see \"Deployment policy\").\n4. Only now: `set_feature_flag(flag, environment=\"production\", enabled=true,\n   rollout_percent=10)`.\n\n## Initial rollout must not exceed 10%\n\nThe first production enablement is capped at **10%**. Sit there long enough to\nsee real traffic - at minimum one full traffic peak - and watch the owning\nservice's error rate and p99. Then ramp: 10 - 25 - 50 - 100, checking metrics at\neach step.\n\nFlags are **runtime toggles**: `set_feature_flag` takes effect immediately and\nneeds **no deploy**. That cuts both ways - it is why a flag is the fastest kill\nswitch we have, and it is why an unreviewed ramp to 100% is the fastest way to\ncause a sev2. The `instant_refunds` incident was exactly this: the flag went to\n100% in production and `checkout` `error_rate_pct` went from 0.3% to 5.5%.\n\n## Kill switch\n\nDuring an incident, disable the flag in the affected environment only. Leave the\nother environment as it is so you can still reproduce. See \"Incident response\".\n\n## Cleanup\n\n**Stale flags must be cleaned up after full rollout.** Once a flag has been at\n100% in production for two weeks and there is no plan to turn it off, remove the\nconditional from the code and delete the flag in a follow-up PR. Every flag left\nbehind is a branch of untested code and a future outage. The owning team reviews\nits flag list at each sprint boundary.\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"

In the one week we ran\n  origin-only during a migration, media egress was roughly 20x the normal line\n  item.\n- Origin bandwidth saturates first during traffic spikes, and image failures\n  make the storefront look broken even when checkout is perfectly healthy.\n\n## Config\n\n| Key             | Production value | Notes                                   |\n| --------------- | ---------------- | --------------------------------------- |\n| `cdn_enabled`   | `true`           | Required.                               |\n\nCache-control defaults: immutable, content-hashed asset URLs get a one-year\nmax-age; mutable paths get 300s with revalidation. Because asset URLs are\ncontent-hashed, a new image is a new URL - you should almost never need to purge.\n\n## Purging\n\nPurge only for a legal or trademark takedown, or for an asset published in\nerror. A full-prefix purge is effectively a cold cache: expect an origin load\nspike and a temporary p99 regression. Purge narrowly, by exact URL, during low\ntraffic.\n\n## Troubleshooting\n\n- Images slow but HTML fast: check `cdn_enabled` first, before anything else.\n- Cache hit ratio below 90%: usually a query string added to asset URLs, which\n  fragments the cache key. Strip non-semantic query parameters at the edge.\n- 403s from the edge: signed-URL clock skew on the origin.\n\n## Changing it\n\nRepo config: PR with a `config` change, CI, merge, staging, then production per\nthe \"Deployment policy\". Verify p99 on a product-detail page and the edge hit\nratio before closing the ticket.\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"

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 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"

+The overnight on-call handover left an unresolved production judgement for the incoming engineer. Keep this to an investigation; production should remain unchanged. OPS-160 — Root cause: analytics cannot read the replica since the rotation Get to the bottom of analytics-cannot-read-replica: not just which service, but the mechanism and the exact setting responsible. The service's own code is not necessarily where this lives — confirm it against the state of the system rather than inferring it from the symptom alone. Leave an audit-ready diagnosis for 'analytics-cannot-read-replica' that names the responsible service, the fault type, the offending key, and your evidence. The work item is DOB-002 for analytics-worker. Its business boundary is reporting freshness, warehouse replica access, scheduled rollups, and downstream decision data. The disputed mechanism is database authorization, revoked roles, credential scope, and least-privilege access. Reconcile current authority with live state, make only supported changes, and leave a case-room handoff that you have reopened and verified.
