-- Config struct / env var → `docs/configuration.md`, `config.yaml`, compose files, `docs/deployment.md`

-## Quick Reference
-
-- **Language**: Go 1.25, strict formatting (`gofumpt`)
-- **Router**: Chi v5 (`github.com/go-chi/chi/v5`)
-- **Logging**: `log/slog` with JSON handler
-- **Testing**: `testing` + `testify` for assertions
-- **Linting**: golangci-lint v2 (see `.golangci.yml`)

-## Key Rules
-
-1. **Tenant ID comes only from JWT** — never read `tenant_id` from request body, query params, or headers.
-2. **Interface-first** — define interfaces where consumed, implement separately for standalone and (future) clustered mode.
-3. **Return errors, don't panic** — wrap with `fmt.Errorf("context: %w", err)`.
-4. **MANDATORY: Keep ALL docs, configs, and examples in sync** — every code change MUST include updates to all affected documentation, config files, Docker Compose files, examples, and CHANGELOG.md. Do NOT wait for the user to ask. See the full "Documentation & Consistency Sync" section in [AGENTS.md](../AGENTS.md) for the complete checklist and cross-referencing rules. A code change without its documentation counterpart is considered incomplete.
-5. **Verify before finishing** — before completing any task, search docs for identifiers you touched (field names, env vars, endpoints, struct names) and fix any stale references.
-6. **Every new function must have tests** — use table-driven tests, shared mocks from `internal/testutil/`, and aim for 80%+ coverage. Run `make lint` and `make test` before considering work complete.
-7. **Use testutil helpers** — use `MockPublisher`, `MockCache`, `MockDeduplicator`, `MockSubscriber` from `testutil/mocks.go` instead of creating ad-hoc mocks. Use `testutil.MakeJWT()` for auth tests. Use `policy.NewMemoryStore(p)` for policy tests. Use `pipes.NewMemoryStore(queries...)` for pipes tests.
-8. **Validate locally before pushing** — run `make ci` (or at minimum `make coverage`) in your sandbox and confirm it passes before opening or updating a PR. The repo runs on a shared self-hosted runner pool with finite throughput and bills AI-reviewer credits per push; a speculative commit to "see what CI says" costs real minutes and dollars. If a test passes locally but flakes on CI, investigate the runner environment before patching the test — see the "Local-First Validation" section in [AGENTS.md](../AGENTS.md) for full guidance.

 ## What to read before reviewing
 
-The PR number you're reviewing is in the header above. Before
-forming an opinion, read the **whole PR**, not just the most
-recent commit:
-
-1. **The full PR diff (HEAD vs the merge base with the target
-   branch)** — `gh pr diff <num>` or read each changed file at
-   the PR head SHA. **Do NOT only review the latest commit's
-   diff.** Reviews focused on the latest push miss issues that
-   prior commits introduced and that the latest commit didn't
-   touch. The merge-base diff is the unit of review; a commit
-   is just a checkpoint inside it.
-
-2. **All prior comments and reviews on this PR** —
-   `gh pr view <num> --json comments,reviews` (and the inline
-   review-comment endpoint
-   `gh api repos/<repo>/pulls/<num>/comments` for line-level
-   comments). If a reviewer (human or other bot) already
-   flagged something, don't re-flag it; either acknowledge
-   their finding briefly or add nuance. If the author replied
-   to a concern, factor in their reply — don't re-raise a
-   resolved point.
-
-3. **Linked issues** — anything referenced in the PR body via
-   `Closes #N` / `Fixes #N` / `Resolves #N`. The acceptance
-   criteria for the PR live in the linked issue; review against
-   those, not just against the diff in isolation.
-
-4. **CI run logs** — only when the diff touches workflow / build
-   / test infrastructure (`.github/`, `Makefile`, `Dockerfile*`,
-   `tests/compose.yaml`). Read the most recent CI run on this
-   PR's head SHA; flag anything that passed CI but looks
-   suspicious in the logs.
-
-The action's environment provides `gh` CLI authenticated to
-this repo, so the commands above all work directly.

-positive is cheap (reply with a rebuttal), a missed real

 ## Focus areas
 
 Review against each of these, in this order:
 
-1. **Correctness** — Go concurrency (goroutine leaks, data
-   races, missing context propagation, channel leaks,
-   `sync.Once` / `sync.Map` misuse, handlers ignoring
-   `r.Context()`), error wrapping with `%w`, resource
-   cleanup on every error path (`defer` that ignores Close
-   errors is OK when intentional, but flag if the error
-   could mask data loss), invariants preserved (schema
-   validation before DB writes, policy enforcement,
-   tenant/role isolation).

 2. **Security** — walk the OWASP Top 10 against the diff:
-     - SQL injection in any ClickHouse-bound path
-       (`BindParams`, query builders, dynamic table names)
-     - Broken authentication / authorization (JWT claim
-       handling, role extraction, policy templating)
-     - Sensitive data exposure (secrets in logs, error
-       messages leaking internal state)
-     - Broken access control (policy bypass, raw-SQL
-       without `raw_sql: true` permission)
-     - Security misconfiguration (CORS, TLS, default
-       credentials, permissive defaults)
-     - Insufficient logging / monitoring
-     - SSRF, XXE, deserialization flaws if touched
-     - Hardcoded secrets or credentials
-     - TOCTOU / race conditions in auth or policy paths
-   Rate every security finding with severity: `CRITICAL`,
-   `HIGH`, `MEDIUM`, `LOW`, or `NONE` and include it in the
-   comment. Flag `CRITICAL` / `HIGH` prominently in the
-   summary.
-
-3. **Performance** — hot-path allocation in ingest / query /
-   cache, unbounded goroutine spawns, unbatched DB work,
-   missing caching where cost is high, locks held across
-   I/O, N+1 query patterns, singleflight misuse.
-
-4. **Testing** — new code without tests (especially on
-   critical paths: auth middleware, ingest pipeline, policy
-   evaluation, structured query builder, cache coherence,
-   dedup). Missing edge-case coverage. Mocks where a real
-   integration test would catch more (per the "no mocking
-   DB" rule in the test conventions). Unit tests that
-   don't actually exercise the code path they claim to.
-
-5. **Documentation & doc-sync** — AGENTS.md has a hard rule
-   that code changes affecting API / config / architecture
-   / event format must update `docs/api.md`,
-   `docs/configuration.md`, `docs/architecture.md`,
-   `docs/deployment.md`, `CHANGELOG.md` (under
-   `[Unreleased]`), and the compose files / `config.yaml`
-   defaults. Flag every missed sync. The table in
-   AGENTS.md §"Documentation & Consistency Sync" is
-   authoritative — diff changed files against that map.

-findings.** Call `mcp__github_inline_comment__create_inline_comment`
-with `confirmed: true` for each concrete issue. These become
-real PR review threads that show next to the line in the diff,
-must be resolved before merge (the repo's ruleset has
-`required_review_thread_resolution: true`), and are the same
-mechanism Gemini Code Assist uses. *Do not* dump every
-finding into one giant prose blob — that pattern caused the
-sticky comment to bloat.
-
-**Tag every inline comment with exactly one severity** at the
-start of the body: `[MUST]`, `[SHOULD]`, or `[MAY]`. This
-matches `.gemini/styleguide.md` so both reviewers speak the
-same language and the author can filter on tag.
-
-  - `[MUST]` — correctness bug, security issue, broken
-    invariant, missing required documentation sync. The PR
-    can't merge until this is addressed.
-  - `[SHOULD]` — quality / maintainability issue the author
-    should fix, but isn't a release blocker if they push back
-    with reasoning.
-  - `[MAY]` — minor suggestion, style nit, alternative
-    approach. Take or leave.
-
-**Use the sticky summary comment for the verdict only.** One
-short top-level comment with:
-  - A one-line headline grouping findings by severity (e.g.
-    "2 [MUST], 1 [SHOULD], 0 [MAY]").
-  - A pointer to read the inline threads for detail.
-  - The verdict line, **exactly one of**: `Ship it`,
-    `Iterate`, or `Block`, followed by the single most
-    important thing the author must address.
