+# IT Triage Report — 2026-04-21
+
+Branch: `main`, starting HEAD `90460705` (chore: refresh GitNexus index stats).
+
+## Summary
+
+- **Starting state**: 65 IT failures (46 F + 19 E) out of 555 tests on a clean build. Side-note: `target/classes` incremental-build staleness from the `90083f88` V1..V18 → V1 schema collapse makes the number look worse (every context load dies on `Flyway V2__claim_mapping.sql failed`). A fresh `mvn clean verify` gives the real 65.
+- **Final state**: **12 failures across 3 test classes** (`AgentSseControllerIT`, `SseSigningIT`, `ClickHouseStatsStoreIT`). **53 failures closed across 14 test classes.**
+- **11 commits landed on local `main`** (not pushed).
+- No new env vars, endpoints, tables, or columns added. `V1__init.sql` untouched. No tests rewritten to pass-by-weakening — every assertion change is accompanied by a comment explaining the contract it now captures.

+
+## The single biggest insight
+
+**`ExecutionController` (legacy PG path) is dead code.** It's `@ConditionalOnMissingBean(ChunkAccumulator.class)` and `ChunkAccumulator` is registered **unconditionally** in `StorageBeanConfig.java:92`, so `ExecutionController` never binds. Even if it did, `IngestionService.upsert` → `ClickHouseExecutionStore.upsert` throws `UnsupportedOperationException("ClickHouse writes use the chunked pipeline")` — the only `ExecutionStore` impl in `src/main/java` is ClickHouse, the Postgres variant lives in a planning doc only.
+
+Practical consequences for every IT that was exercising `/api/v1/data/executions`:
+1. `ChunkIngestionController` owns the URL and expects an `ExecutionChunk` envelope (`exchangeId`, `applicationId`, `instanceId`, `routeId`, `status`, `startTime`, `endTime`, `durationMs`, `chunkSeq`, `final`, `processors: FlatProcessorRecord[]`) — the legacy `RouteExecution` shape was being silently degraded to an empty/degenerate chunk.
+2. The test payload changes are accompanied by assertion changes that now go through REST endpoints instead of raw SQL against the (ClickHouse-resident) `executions` / `processor_executions` / `route_diagrams` / `agent_metrics` tables.
+3. **Recommendation for cleanup**: remove `ExecutionController` + the `upsert` path in `IngestionService` + the stubbed `ClickHouseExecutionStore.upsert` throwers. Separate PR. Happy to file.
+
+## Cluster breakdown
+
+**Cluster A — missing `environmentId` in register bodies (DONE)**
+Root cause: `POST /api/v1/agents/register` now 400s without `environmentId`. Test payloads minted before this requirement. Fixed across all agent-registering ITs plus side-cleanups (flaky iat-coupled assertion in JwtRefreshIT, wrong RBAC target in can-access tests, absolute vs relative sseEndpoint).
+
+**Cluster B — ingestion payload drift (DONE per user direction)**
+All controller + storage ITs that posted `RouteExecution` JSON now post `ExecutionChunk` envelopes. All CH-side assertions now go through REST endpoints (`/api/v1/environments/{env}/executions` search + `/api/v1/executions/{id}` detail + `/agents/{id}/metrics` + `/apps/{app}/routes/{route}/diagram`). DiagramRenderControllerIT's SVG tests still need a content hash → reads it off the execution-detail REST response rather than querying `route_diagrams`.
+
+**Cluster C — flat URL drift (DONE)**
+`/api/v1/agents` → `/api/v1/environments/{envSlug}/agents`. Two test classes touched.
+
+**Cluster D — heartbeat auto-heal contract (DONE)**
+`heartbeatUnknownAgent_returns404` renamed and asserts the 200 auto-heal path that `fb54f9cb` made the contract.
+
+**Cluster E — individual drifts (DONE except three parked)**
+
+| Test class | Status |
+|---|---|
+| FlywayMigrationIT | DONE (decouple from shared PG state) |
+| ConfigEnvIsolationIT.findByEnvironment_excludesOtherEnvs | DONE (unique slug prefix) |
+| ForwardCompatIT | DONE (chunk payload) |
+| ProtocolVersionIT | DONE (chunk payload) |
+| BackpressureIT | DONE (property-key prefix fix — see note below) |
+| SensitiveKeysAdminControllerIT | DONE (assert shape not count) |
+| ClickHouseChunkPipelineIT | DONE (consolidated init.sql) |
+| ClickHouseExecutionReadIT | DONE (iteration vs loopIndex mapping) |
+
+## PARKED — what you'll want to look at next
+
+### 1. ClickHouseStatsStoreIT (8 failures) — timezone bug in production code
+
+`ClickHouseStatsStore.buildStatsSql` uses `lit(Instant)` which formats as `'yyyy-MM-dd HH:mm:ss'` in UTC but with no timezone marker. ClickHouse parses that literal in the session timezone when comparing against the `DateTime`-typed `bucket` column in `stats_1m_*`. On a non-UTC CH host (e.g. CEST docker on a CEST laptop), the filter endpoint is off by the tz offset in hours and misses every row the MV bucketed.
+
+I confirmed this by instrumenting the test: `toDateTime(bucket)` returned `12:00:00` for a row inserted with `start_time=10:00:00Z` (i.e. the stored UTC Unix timestamp but displayed in CEST), and the filter literal `'2026-03-31 10:05:00'` was being parsed as CEST → UTC 08:05 → excluded all rows.
+
+**I didn't fix this** because the repair is in `src/main/java`, not the test. Two reasonable options:
+- **Test-side**: pin the container TZ via `.withEnv("TZ", "UTC")` + include `use_time_zone=UTC` in the JDBC URL. I tried both; neither was sufficient on their own — the CH server reads `timezone` from its own config, not `$TZ`. Getting all three layers (container env, CH server config, JDBC driver) aligned needs dedicated effort.
+- **Production-side (preferred)**: change `lit(Instant)` to `toDateTime('...', 'UTC')` or use the 3-arg `DateTime(3, 'UTC')` column type for `bucket`. That's a store change; would be caught by a matching unit test.
+
+I did add the explicit `'default'` env to the seed `INSERT`s per your directive, but reverted it locally because the timezone bug swallowed the fix. The raw unchanged test is what's committed.
+
+### 2. AgentSseControllerIT (3 failures) & SseSigningIT (1 failure) — SSE connection timing
+
+All failing assertions are `awaitConnection(5000)` timeouts or `ConditionTimeoutException` on SSE stream observation. Not related to any spec drift I could identify — the SSE server is up (other tests in the same classes connect fine), and auth/JWT is accepted. Looks like a real race on either the SseConnectionManager registration or on the HTTP client's first-read flush. Needs a dedicated debug session with a minimal reproducer; not something I wanted to hack around with sleeps.
+
+Specific tests:
+- `AgentSseControllerIT.sseConnect_unknownAgent_returns404` — 5s `CompletableFuture.get` timeout on an HTTP GET that should return 404 synchronously. Suggests the client is waiting on body data that never arrives (SSE stream opens even on 404?).
+- `AgentSseControllerIT.lastEventIdHeader_connectionSucceeds` — `stream.awaitConnection(5000)` false.
+- `AgentSseControllerIT.pingKeepalive_receivedViaSseStream` — waits for an event line in the stream snapshot, never sees it.
+- `SseSigningIT.deepTraceEvent_containsValidSignature` — same pattern.
+
+The sibling tests (`SseSigningIT.configUpdateEvent_containsValidEd25519Signature`) pass in isolation, which strongly suggests order-dependent flakiness rather than a protocol break.
+
+## Final verify command
+
+```bash
+mvn -pl cameleer-server-app -am -Dit.test='!SchemaBootstrapIT' -Dtest='!*' -DfailIfNoTests=false -Dsurefire.failIfNoSpecifiedTests=false verify
+```
+
+Reports land in `cameleer-server-app/target/failsafe-reports/`. Expect **12 failures** in the three classes above. Everything else is green.
+
+## Side notes worth flagging
+
+- **Property-key inconsistency in the main code** — surfaced via BackpressureIT. `IngestionConfig` is bound under `cameleer.server.ingestion.*`, but `MetricsFlushScheduler.@Scheduled` reads `ingestion.flush-interval-ms` (no prefix, hyphenated). In production this means the flush-interval in `application.yml` isn't actually being honoured by the metrics flush — it stays at the 1s fallback. Separate cleanup.
+- **Shared Testcontainers PG across IT classes** — several of the "cross-test state" fixes (FlywayMigrationIT, ConfigEnvIsolationIT, SensitiveKeysAdminControllerIT) are symptoms of one underlying issue: `AbstractPostgresIT` uses a singleton PG container, and nothing cleans between test classes. Could do with a global `@Sql("/test-reset.sql")` on `@BeforeAll`, but out of scope here.
+- **Agent registry shared across ITs** — same class of issue. Doesn't bite until a test explicitly inspects registry membership (SensitiveKeys `pushResult.total`).
+
+## Follow-up (2026-04-22) — 12 parked failures closed
+
+All three parked clusters now green. 560/560 tests passing.
+
+- **ClickHouseStatsStoreIT (8 failures)** — fixed in `a9a6b465`. Two-layer TZ fix: JVM default TZ pinned to UTC in `CameleerServerApplication.main()` (the ClickHouse JDBC 0.9.7 driver formats `java.sql.Timestamp` via `Timestamp.toString()`, which uses JVM default TZ — a CEST JVM shipping to a UTC CH server stored off-by-offset Unix timestamps), plus column-level `bucket DateTime('UTC')` on all `stats_1m_*` tables with explicit `toDateTime(..., 'UTC')` casts in MV projections and `ClickHouseStatsStore.lit(Instant)` as defence in depth.
+- **MetricsFlushScheduler property-key drift** — fixed in `a6944911`. Scheduler now reads `${cameleer.server.ingestion.flush-interval-ms:1000}` (the SpEL-via-`@ingestionConfig` approach doesn't work because `@EnableConfigurationProperties` uses a compound bean name). BackpressureIT workaround property removed.
+- **SSE flakiness (4 failures, `AgentSseControllerIT` + `SseSigningIT`)** — fixed in `41df042e`. Triage's "order-dependent flakiness" theory was wrong — all four reproduced in isolation. Three root causes: (a) `AgentSseController.events` auto-heal was over-permissive (spoofing vector), fixed with JWT-subject-equals-path-id check; (b) `SseConnectionManager.pingAll` read an unprefixed property key (`agent-registry.ping-interval-ms`), same family of bug as (a6944911); (c) SSE response headers didn't flush until the first `emitter.send()`, so `awaitConnection(5s)` assertions timed out under the 15s ping cadence — fixed by sending an initial `: connected` comment on `connect()`. Full diagnosis in `.planning/sse-flakiness-diagnosis.md`.
+
+Plus the two prod-code cleanups from the ExecutionController-removal follow-ons:
+
+- **Dead `SearchIndexer` subsystem** — removed in `98cbf8f3`. `ExecutionUpdatedEvent` had no publisher after `0f635576`, so the whole indexer + stats + `/admin/clickhouse/pipeline` endpoint + UI pipeline card carried zero signal.
+- **Unused `TaggedExecution` record** — removed in `06c6f53b`.
+
+Final verify: `mvn -pl cameleer-server-app -am -Dit.test='!SchemaBootstrapIT' ... verify` → **Tests run: 560, Failures: 0, Errors: 0, Skipped: 0**.

+# SSE Flakiness — Root-Cause Analysis
+
+**Date:** 2026-04-21
+**Tests:** `AgentSseControllerIT.sseConnect_unknownAgent_returns404`, `.lastEventIdHeader_connectionSucceeds`, `.pingKeepalive_receivedViaSseStream`, `SseSigningIT.deepTraceEvent_containsValidSignature`
+
+## Summary
+
+Not order-dependent flakiness (triage report was wrong). Three distinct root causes, one production bug and one test-infrastructure issue, all reproducible when running the classes in isolation.
+
+## Reproduction
+
+```bash
+mvn -pl cameleer-server-app -am -Dit.test='AgentSseControllerIT' -Dtest='!*' \
+    -DfailIfNoTests=false -Dsurefire.failIfNoSpecifiedTests=false verify
+```
+
+Result: 3 failures out of 7 tests with a cold CH container. Not order-dependent.
+
+## Root causes
+
+### 1. `AgentSseController.events` auto-heal is over-permissive (security bug)
+
+**File:** `cameleer-server-app/src/main/java/com/cameleer/server/app/controller/AgentSseController.java:63-76`
+
+```java
+AgentInfo agent = registryService.findById(id);
+if (agent == null) {
+    var jwtResult = ...;
+    if (jwtResult != null) {     // ← only checks JWT presence
+        registryService.register(id, id, application, env, ...);
+    } else {
+        throw 404;
+    }
+}
+```
+
+**Bug:** auto-heal registers *any* path id when any valid JWT is present, regardless of whether the JWT subject matches the path id. A holder of agent X's JWT can open SSE for any path-id Y, silently spoofing Y.
+
+**Surface symptom:** `sseConnect_unknownAgent_returns404` sends a JWT for `test-agent-sse-it` and requests SSE for `unknown-sse-agent`. Auto-heal kicks in, returns 200 with an infinite empty stream. Test's `statusFuture.get(5s)` — which uses `BodyHandlers.ofString()` and waits for the full body — times out instead of getting a synchronous 404.
+
+**Fix:** only auto-heal when `jwtResult.subject().equals(id)`.
+
+### 2. `SseConnectionManager.pingAll` reads an unprefixed property key (production bug)
+
+**File:** `cameleer-server-app/src/main/java/com/cameleer/server/app/agent/SseConnectionManager.java:172`
+
+```java
+@Scheduled(fixedDelayString = "${agent-registry.ping-interval-ms:15000}")
+```
+
+**Bug:** `AgentRegistryConfig` is `@ConfigurationProperties(prefix = "cameleer.server.agentregistry")`. The scheduler reads an unprefixed `agent-registry.*` key that the YAML never defines — so the default 15s always applies, regardless of config. Same family of bug as the `MetricsFlushScheduler` fix in commit `a6944911`.
+
+**Fix:** `${cameleer.server.agentregistry.ping-interval-ms:15000}`.
+
+### 3. SSE response body doesn't flush until first event (test timing dependency)
+
+**File:** `cameleer-server-app/src/main/java/com/cameleer/server/app/agent/SseConnectionManager.java:connect()`
+
+Spring's `SseEmitter` holds the response open but doesn't flush headers to the client until the first `emitter.send()`. Until then, clients using `HttpResponse.BodyHandlers.ofInputStream()` block on the first byte.
+
+**Surface symptom:**
+- `lastEventIdHeader_connectionSucceeds` — asserts `awaitConnection(5000)` is `true`. The latch counts down in `.thenAccept(response -> ...)`, which in practice only fires once body bytes start flowing (JDK 21 behaviour with SSE streams). Default ping cadence is 15s → 5s assertion times out.
+- `pingKeepalive_receivedViaSseStream` — waits 5s for a `:ping` line. The scheduler runs every 15s (both by default, and because of bug #2, unconditionally).
+- `SseSigningIT.deepTraceEvent_containsValidSignature` — same family: `awaitConnection(5000).isTrue()`.
+
+**Fix:** send an initial `: connected` comment as part of `connect()`. Spring flushes on the first `.send()`, so an immediate comment forces the response headers + first byte to hit the wire, which triggers the client's `thenAccept` callback. Also solves the ping-test: the initial comment is observed as a keepalive line within the test's polling window.
+
+## Hypothesis ladder (ruled out)
+
+- **Order-dependent singleton leak** — ruled out: every failure reproduces when the class is run solo.
+- **Tomcat async thread pool exhaustion** — ruled out: `SseEmitter(Long.MAX_VALUE)` does hold threads, but the 7-test class doesn't reach Tomcat's defaults.
+- **SseConnectionManager emitter-map contamination** — ruled out: each test uses a unique agent id (UUID-suffixed), and the `@Component` is the same instance across tests but the emitter map is keyed by agent id, no collisions.
+
+## Verification
+
+```
+mvn -pl cameleer-server-app -am -Dit.test='AgentSseControllerIT,SseSigningIT' ... verify
+# Tests run: 9, Failures: 0, Errors: 0, Skipped: 0
+```
+
+All 9 tests green with the three fixes applied.

+# IT Triage Follow-Ups Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Close the 12 parked IT failures from `.planning/it-triage-report.md` plus two prod-code side-notes, so `mvn -pl cameleer-server-app -am -Dit.test='!SchemaBootstrapIT' verify` returns **0 failures**.
+
+**Architecture:** Four focused fixes (CH timezone, scheduler property key, two dead-code removals) executed atomically, each with its own commit. Then SSE flakiness as diagnose-then-fix. User is asleep during execution — no interactive checkpoint; if SSE diagnosis is inconclusive within the timebox, park the 4 failing SSE tests with `@Disabled` + link to the diagnosis doc and finish the rest green.
+
+**Tech Stack:** Java 17, Spring Boot 3.4.3, ClickHouse 24.12 via JDBC, Testcontainers, Maven Failsafe.
+
+---
+
+## Execution policy
+
+- **Atomic commits** — one task, one commit, scoped to the task's files.
+- **Before each symbol edit:** `gitnexus_impact({target, direction: "upstream"})`. Warn on HIGH/CRITICAL. Stop if unexpected dependents appear and re-scope.
+- **Before each commit:** `gitnexus_detect_changes({scope: "staged"})`. Confirm scope.
+- **`.claude/rules/*` updates** are part of the same commit as the class change, not a separate task.
+- **Test-only scope** — no tests rewritten to pass-by-weakening. Every change to an assertion gets a comment explaining the contract it now captures.
+- **Final step** — `git push origin main` after all tasks commit and the full verify run is green (or yellow with the parked SSE tests only, clearly noted).
+
+---
+
+## Task 0 — Baseline verify (evidence, no commit)
+
+**Files:** none modified.
+
+- [ ] **Step 0.1: Run baseline failing tests to confirm starting state**
+
+```bash
+mvn -pl cameleer-server-app -am -Dit.test='ClickHouseStatsStoreIT,AgentSseControllerIT,SseSigningIT,BackpressureIT' -Dtest='!*' -DfailIfNoTests=false -Dsurefire.failIfNoSpecifiedTests=false verify 2>&1 | tail -60
+```
+
+Expected: **12 failures** distributed across those three IT classes, matching `.planning/it-triage-report.md`. If the baseline count differs, stop and re-audit — the spec assumes this number.
+
+- [ ] **Step 0.2: Record baseline to memory**
+
+Keep the failure count as the reference number. The final verify must show 0 new failures; the only acceptable regression is the SSE cluster if and only if Task 5 parks them (and the user-facing summary notes this).
+
+---
+
+## Task 1 — ClickHouse timezone fix
+
+Closes 8 failures in `ClickHouseStatsStoreIT`.
+
+**Files:**
+- Modify: `cameleer-server-app/src/main/resources/clickhouse/init.sql`
+- Modify: `cameleer-server-app/src/main/java/com/cameleer/server/app/storage/ClickHouseStatsStore.java:346-350`
+- Modify: `cameleer-server-app/src/test/java/com/cameleer/server/app/storage/ClickHouseStatsStoreIT.java:49-78` (remove debug scaffolding from the triage investigation)
+
+- [ ] **Step 1.1: Impact analysis**
+
+Run `gitnexus_impact({target: "ClickHouseStatsStore", direction: "upstream"})`. Expected: `SearchService`, `SearchController`, alerting evaluator. Note the blast radius — every read-path that uses `stats_1m_*` tables sees the now-correct values.
+
+- [ ] **Step 1.2: Change `init.sql` — `bucket` columns to `DateTime('UTC')`, MV SELECTs to emit UTC**
+
+Edit `cameleer-server-app/src/main/resources/clickhouse/init.sql`:
+
+For each of the five stats tables (`stats_1m_all`, `stats_1m_app`, `stats_1m_route`, `stats_1m_processor`, `stats_1m_processor_detail`), change the `bucket` column declaration from:
+
+```sql
+    bucket         DateTime,
+```
+
+to:
+
+```sql
+    bucket         DateTime('UTC'),
+```
+
+For each of the five materialized views (`stats_1m_all_mv`, `stats_1m_app_mv`, `stats_1m_route_mv`, `stats_1m_processor_mv`, `stats_1m_processor_detail_mv`), change the bucket projection from:
+
+```sql
+    toStartOfMinute(start_time)           AS bucket,
+```
+
+to:
+
+```sql
+    toDateTime(toStartOfMinute(start_time), 'UTC') AS bucket,
+```
+
+The `TTL bucket + INTERVAL 365 DAY DELETE` lines need no change — TTL interval arithmetic is tz-agnostic.
+
+- [ ] **Step 1.3: Verify `ClickHouseStatsStore.lit(Instant)` literal works against the typed column**
+
+Read `ClickHouseStatsStore.java:346-350`. The current formatter writes `'yyyy-MM-dd HH:mm:ss'` with `ZoneOffset.UTC`:
+
+```java
+private static String lit(Instant instant) {
+    return "'" + java.time.format.DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss")
+            .withZone(java.time.ZoneOffset.UTC)
+            .format(instant.truncatedTo(ChronoUnit.SECONDS)) + "'";
+}
+```
+
+With `bucket DateTime('UTC')`, a bare literal like `'2026-03-31 10:05:00'` is parsed by ClickHouse as being in the column's TZ (UTC). So `bucket >= '2026-03-31 10:05:00'` now compares UTC-to-UTC consistently. No code change required in `lit(Instant)` — leave it alone.
+
+**However**, for defence-in-depth (so a future reader or refactor doesn't reintroduce the bug), wrap the formatted string in an explicit `toDateTime('...', 'UTC')` cast. Change the method to:
+
+```java
+/**
+ * Format an Instant as a ClickHouse DateTime literal explicitly typed in UTC.
+ * The explicit `toDateTime(..., 'UTC')` cast avoids depending on the session
+ * timezone matching the `bucket DateTime('UTC')` column type.
+ */
+private static String lit(Instant instant) {
+    String raw = java.time.format.DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss")
+            .withZone(java.time.ZoneOffset.UTC)
+            .format(instant.truncatedTo(ChronoUnit.SECONDS));
+    return "toDateTime('" + raw + "', 'UTC')";
+}
+```
+
+Note: this affects both `bucket >= ...` comparisons and `tenant_id = ...` elsewhere — but `tenant_id` uses the `lit(String)` overload. Only `lit(Instant)` is touched.
+
+- [ ] **Step 1.4: Remove debug scaffolding from `ClickHouseStatsStoreIT.setUp()`**
+
+Lines 49-78 currently contain a try-catch that runs a failing query, flushes logs, prints query log entries to stdout. This was diagnostic code from the triage investigation; it's no longer needed and pollutes CI output.
+
+Edit `cameleer-server-app/src/test/java/com/cameleer/server/app/storage/ClickHouseStatsStoreIT.java`, replacing the current `setUp()` body with:
+
+```java
+@BeforeEach
+void setUp() throws Exception {
+    HikariDataSource ds = new HikariDataSource();
+    ds.setJdbcUrl(clickhouse.getJdbcUrl());
+    ds.setUsername(clickhouse.getUsername());
+    ds.setPassword(clickhouse.getPassword());
+
+    jdbc = new JdbcTemplate(ds);
+
+    ClickHouseTestHelper.executeInitSql(jdbc);
+
+    // Truncate base tables
+    jdbc.execute("TRUNCATE TABLE executions");
+    jdbc.execute("TRUNCATE TABLE processor_executions");
+
+    seedTestData();
+
+    store = new ClickHouseStatsStore("default", jdbc);
+}
+```
+
+And remove the now-unused imports: `import java.nio.charset.StandardCharsets;` (line 16) — keep everything else, the rest is still used by `seedTestData` and the tests.
+
+- [ ] **Step 1.5: Run the 8 failing ITs**
+
+```bash
+mvn -pl cameleer-server-app -am -Dit.test='ClickHouseStatsStoreIT' -Dtest='!*' -DfailIfNoTests=false -Dsurefire.failIfNoSpecifiedTests=false verify 2>&1 | tail -40
+```
+
+Expected: **0 failures, 15 passed** (`ClickHouseStatsStoreIT` has 14 tests; count may vary — the baseline says 8 failures out of the full class count). If any failure remains, root-cause it:
+- If literal format is wrong → verify the `toDateTime(..., 'UTC')` cast renders correctly
+- If MV isn't emitting → the MV source expression now needs the explicit UTC wrap
+- If a different test that was previously passing now fails → CH schema change broke a reader; `gitnexus_impact` identifies who.
+
+- [ ] **Step 1.6: Verify GitNexus impact surface**
+
+```bash
+gitnexus_detect_changes({scope: "staged"})
+```
+
+Expected: `init.sql`, `ClickHouseStatsStore.java`, `ClickHouseStatsStoreIT.java`. Nothing else.
+
+- [ ] **Step 1.7: Commit**

+fix(stats): store bucket as DateTime('UTC') so reads don't depend on CH session TZ
+
+ClickHouseStatsStoreIT had 8 failures when the CH container's session
+timezone was non-UTC (e.g. CEST): stats filter literals were parsed in
+session TZ while the bucket column stored UTC Unix timestamps, and every
+time-range query missed rows by the tz offset.
+
+- init.sql: bucket columns on all stats_1m_* tables typed as
+  DateTime('UTC'); MV SELECTs wrap toStartOfMinute(start_time) in
+  toDateTime(..., 'UTC') so projections match the target column type.
+- ClickHouseStatsStore.lit(Instant): emit toDateTime('...', 'UTC') cast
+  rather than a bare literal, as defence-in-depth against future
+  refactors that change column typing.
+- ClickHouseStatsStoreIT.setUp: remove debug scaffolding (failing-query

+## Task 2 — MetricsFlushScheduler property-key fix
+
+Fixes the production bug that `flush-interval-ms` YAML config was silently ignored. No IT failures directly depend on this (BackpressureIT worked around it with a second property), but the workaround is no longer needed after the fix.
+
+**Files:**
+- Modify: `cameleer-server-app/src/main/java/com/cameleer/server/app/ingestion/MetricsFlushScheduler.java:33`
+- Modify: `cameleer-server-app/src/test/java/com/cameleer/server/app/controller/BackpressureIT.java:24-36`
+
+- [ ] **Step 2.1: Impact analysis**
+
+```bash
+gitnexus_impact({target: "MetricsFlushScheduler", direction: "upstream"})
+gitnexus_impact({target: "IngestionConfig.getFlushIntervalMs", direction: "upstream"})
+```
+
+Expected: only `MetricsFlushScheduler` consumes `flushIntervalMs`. If another `@Scheduled` uses the unprefixed key, fix it too (it has the same bug).
+
+Verify `IngestionConfig` bean name:
+
+```bash
+grep -rn "EnableConfigurationProperties" cameleer-server-app/src/main/java
+```
+
+Expected: `CameleerServerApplication.java` has `@EnableConfigurationProperties({IngestionConfig.class, AgentRegistryConfig.class})`. Spring registers the bean with the default name derived from the class simple name: `ingestionConfig` (camelCase first-letter-lower). SpEL `@ingestionConfig` resolves to this bean.
+
+- [ ] **Step 2.2: Change `MetricsFlushScheduler.@Scheduled` to SpEL**
+
+Edit `cameleer-server-app/src/main/java/com/cameleer/server/app/ingestion/MetricsFlushScheduler.java`. Replace line 33:
+
+```java
+    @Scheduled(fixedDelayString = "${ingestion.flush-interval-ms:1000}")
+```
+
+with:
+
+```java
+    @Scheduled(fixedDelayString = "#{@ingestionConfig.flushIntervalMs}")
+```
+
+No other change to this file.
+
+- [ ] **Step 2.3: Drop the BackpressureIT workaround property**
+
+Edit `cameleer-server-app/src/test/java/com/cameleer/server/app/controller/BackpressureIT.java` lines 24-36. Replace the `@TestPropertySource` block with:
+
+```java
+@TestPropertySource(properties = {
+        // Property keys must match the IngestionConfig @ConfigurationProperties
+        // prefix (cameleer.server.ingestion) exactly. The MetricsFlushScheduler
+        // now binds its @Scheduled flush interval via SpEL on IngestionConfig,
+        // so a single property override controls both the buffer config and
+        // the flush cadence.
+        "cameleer.server.ingestion.buffercapacity=5",
+        "cameleer.server.ingestion.batchsize=5",
+        "cameleer.server.ingestion.flushintervalms=60000"
+})
+```
+
+Removed: the second `ingestion.flush-interval-ms=60000` entry and its comment block.
+
+- [ ] **Step 2.4: Run BackpressureIT**
+
+```bash
+mvn -pl cameleer-server-app -am -Dit.test='BackpressureIT' -Dtest='!*' -DfailIfNoTests=false -Dsurefire.failIfNoSpecifiedTests=false verify 2>&1 | tail -30
+```
+
+Expected: 2 passed, 0 failed. `whenMetricsBufferFull_returns503WithRetryAfter` in particular must still pass — the 60s flush interval must still be honoured, proving the SpEL binding works.
+
+- [ ] **Step 2.5: Smoke test the app bean wiring**
+
+```bash
+mvn -pl cameleer-server-app compile 2>&1 | tail -10
+```
+
+Expected: BUILD SUCCESS. Bean name mismatches between SpEL and the actual bean name usually surface as `IllegalStateException: No bean named 'ingestionConfig' available` at runtime, not at compile time — BackpressureIT in Step 2.4 is the actual smoke test.
+
+- [ ] **Step 2.6: Commit**
+
+```bash
+gitnexus_detect_changes({scope: "staged"})
+# Expected: only MetricsFlushScheduler.java, BackpressureIT.java

+## Task 3 — Delete dead SearchIndexer subsystem
+
+The ExecutionController removal commit (0f635576) left `SearchIndexer.onExecutionUpdated` subscribed to an event (`ExecutionUpdatedEvent`) that nothing publishes. The whole indexer subsystem is dead: every stat method it exposes returns always-zero values, and the admin `/pipeline` endpoint that consumes them is therefore vestigial.
+
+**Files:**
+- Delete: `cameleer-server-core/src/main/java/com/cameleer/server/core/indexing/SearchIndexer.java`
+- Delete: `cameleer-server-core/src/main/java/com/cameleer/server/core/indexing/SearchIndexerStats.java`
+- Delete: `cameleer-server-core/src/main/java/com/cameleer/server/core/indexing/ExecutionUpdatedEvent.java`
+- Delete: `cameleer-server-app/src/main/java/com/cameleer/server/app/dto/IndexerPipelineResponse.java` (if it exists as a standalone DTO — verify in Step 3.2)
+- Modify: `cameleer-server-app/src/main/java/com/cameleer/server/app/controller/ClickHouseAdminController.java` (remove `/pipeline` endpoint, `indexerStats` field, its constructor parameter)
+- Modify: any bean config that creates `SearchIndexer` (discover in Step 3.2)
+- Modify: `ui/src/api/queries/admin/clickhouse.ts` if it calls `/pipeline` (discover in Step 3.2)
+- Update: `.claude/rules/core-classes.md` (remove SearchIndexer/SearchIndexerStats bullets)
+- Update: `.claude/rules/app-classes.md` (remove `/pipeline` endpoint mention)
+
+- [ ] **Step 3.1: Impact analysis**
+
+```bash
+gitnexus_impact({target: "SearchIndexer", direction: "upstream"})
+gitnexus_impact({target: "SearchIndexerStats", direction: "upstream"})
+gitnexus_impact({target: "ExecutionUpdatedEvent", direction: "upstream"})
+gitnexus_impact({target: "IndexerPipelineResponse", direction: "upstream"})
+```
+
+Expected: `ClickHouseAdminController` depends on `SearchIndexerStats`. The other three should have no non-self dependents after the ExecutionController removal. If anything else surprises you, STOP — something is still live and needs re-scoping.
+
+- [ ] **Step 3.2: Discover full footprint**
+
+```bash
+grep -rn "SearchIndexer\|IndexerPipelineResponse\|ExecutionUpdatedEvent" \
+    --include="*.java" --include="*.ts" --include="*.tsx" --include="*.md" \
+    cameleer-server-core/src cameleer-server-app/src ui/src .claude/rules
+```
+
+Expected matches:
+- `SearchIndexer.java`, `SearchIndexerStats.java`, `ExecutionUpdatedEvent.java` themselves
+- `ClickHouseAdminController.java` — has field + constructor param + `/pipeline` endpoint
+- `IndexerPipelineResponse.java` — DTO (check if it exists in `cameleer-server-app/src/main/java/com/cameleer/server/app/dto/`)
+- A bean config file (likely `StorageBeanConfig.java` or a dedicated indexing config) instantiating `SearchIndexer`
+- `ui/src/api/queries/admin/clickhouse.ts` — maybe queries `/pipeline`
+- `.claude/rules/core-classes.md`, `.claude/rules/app-classes.md`
+- design docs under `docs/superpowers/specs/` — leave untouched (historical)
+
+Make a list of every file to edit. Don't proceed until you've seen them all.
+
+- [ ] **Step 3.3: Remove SearchIndexer instantiation from bean config**
+
+Open the file(s) found in Step 3.2 that construct `SearchIndexer`. Delete:
+- the `@Bean SearchIndexer searchIndexer(...)` method
+- the `@Bean SearchIndexerStats searchIndexerStats(...)` method (if it exists separately — usually just returns the `SearchIndexer` instance cast to the interface)
+- any private helper field such as `private final ExecutionStore executionStore;` that becomes unused *only if it was used exclusively for constructing SearchIndexer*; leave fields used by other beans.
+
+If the bean config also pulls in `SearchIndex` purely to pass it to `SearchIndexer`, check whether anything else uses `SearchIndex`. If not, leave the `SearchIndex` bean — it may be used by the search-query path (`SearchController`/`SearchService`). Verify before deleting.
+
+- [ ] **Step 3.4: Remove `/pipeline` endpoint from ClickHouseAdminController**
+
+Edit `cameleer-server-app/src/main/java/com/cameleer/server/app/controller/ClickHouseAdminController.java`:
+
+1. Remove the import `import com.cameleer.server.core.indexing.SearchIndexerStats;`
+2. Remove the import `import com.cameleer.server.app.dto.IndexerPipelineResponse;`
+3. Remove the field `private final SearchIndexerStats indexerStats;`
+4. Remove the constructor parameter `SearchIndexerStats indexerStats` and the `this.indexerStats = indexerStats;` assignment
+5. Remove the entire `@GetMapping("/pipeline") ... public IndexerPipelineResponse getPipeline() { ... }` method
+
+The remaining controller retains `/status`, `/tables`, `/performance`, `/queries` endpoints — those don't depend on the indexer.
+
+- [ ] **Step 3.5: Delete the dead files**
+
+```bash
+git rm cameleer-server-core/src/main/java/com/cameleer/server/core/indexing/SearchIndexer.java
+git rm cameleer-server-core/src/main/java/com/cameleer/server/core/indexing/SearchIndexerStats.java
+git rm cameleer-server-core/src/main/java/com/cameleer/server/core/indexing/ExecutionUpdatedEvent.java
+```
+
+If the indexing package becomes empty:
+
+```bash
+find cameleer-server-core/src/main/java/com/cameleer/server/core/indexing -type d -empty -delete 2>/dev/null
+```
+
+- [ ] **Step 3.6: Delete IndexerPipelineResponse DTO (if standalone)**
+
+If Step 3.2 confirmed `cameleer-server-app/src/main/java/com/cameleer/server/app/dto/IndexerPipelineResponse.java` exists as its own file:
+
+```bash
+git rm cameleer-server-app/src/main/java/com/cameleer/server/app/dto/IndexerPipelineResponse.java
+```
+
+If it's an inner record in another DTO file, leave that file alone and remove only the record definition.
+
+- [ ] **Step 3.7: Remove UI consumer of `/pipeline` (if any)**
+
+If `ui/src/api/queries/admin/clickhouse.ts` or another UI file calls `/api/v1/admin/clickhouse/pipeline`:
+- Remove the query hook / fetch call
+- Remove any UI component rendering its data (likely in an admin page)
+- Run `cd ui && npm run build 2>&1 | tail -20` to surface compile errors from other call sites; fix them by deleting the relevant UI sections
+
+If no UI reference exists, skip this step.
+
+- [ ] **Step 3.8: Regenerate OpenAPI schema**
+
+Per CLAUDE.md: any REST surface change requires regenerating `ui/src/api/schema.d.ts`.
+
+Start the backend:
+
+```bash
+cd cameleer-server-app && mvn spring-boot:run &
+# wait for port 8081 to be listening — poll with: until curl -sf http://localhost:8081/api-docs >/dev/null 2>&1; do sleep 2; done
+```
+
+Regenerate:
+
+```bash
+cd ui && npm run generate-api:live
+```
+
+Stop the backend. Commit includes the regenerated `ui/src/api/schema.d.ts` and `ui/src/api/openapi.json`.
+
+If the user is offline / the backend can't start, skip this step but flag it in the commit message so a follow-up can regenerate. The TypeScript types will be out of sync until then — the build will fail if any UI code referenced `/pipeline` endpoint types.
+
+- [ ] **Step 3.9: Update `.claude/rules/core-classes.md`**
+
+Remove these sections entirely:
+- The `SearchIndexer` bullet (if present in the core-classes rules)
+- Any `SearchIndexerStats` interface bullet
+- Any `ExecutionUpdatedEvent` record mention
+
+The file is currently 100+ lines. Search for "SearchIndexer" and "ExecutionUpdatedEvent" and delete the matching lines/bullets.
+
+- [ ] **Step 3.10: Update `.claude/rules/app-classes.md`**
+
+Remove:
+- The `/pipeline` endpoint mention under `ClickHouseAdminController` (line reading "GET `/api/v1/admin/clickhouse/**` (conditional on `infrastructureendpoints` flag)" can stay — `/pipeline` is no longer listed separately; if there was a specific `/pipeline` bullet, remove it).
+
+Also grep for "SearchIndexer" in the rules and delete any residual mentions.
+
+- [ ] **Step 3.11: Build and verify**
+
+```bash
+mvn -pl cameleer-server-app -am compile 2>&1 | tail -20
+```
+
+Expected: BUILD SUCCESS. If a reference slipped through, the compile fails with a clear `cannot find symbol` pointing at the dead class.
+
+```bash
+mvn -pl cameleer-server-app -am -Dit.test='ClickHouseAdminControllerIT' -Dtest='!*' -DfailIfNoTests=false -Dsurefire.failIfNoSpecifiedTests=false verify 2>&1 | tail -20
+```
+
+If this IT exists and tests `/pipeline`, its test methods for that endpoint must be removed too. Edit the IT file, remove the `/pipeline` test methods. Re-run.
+
+- [ ] **Step 3.12: Commit**
+
+```bash

+## Task 5 — SSE diagnosis
+
+Diagnose the 4 failing SSE tests before attempting a fix. Produces a markdown diagnosis doc, not code changes.
+
+**Files:**
+- Create: `.planning/sse-flakiness-diagnosis.md`
+
+- [ ] **Step 5.1: Run each failing test in isolation to confirm baseline**
+
+```bash
+for t in "AgentSseControllerIT#sseConnect_unknownAgent_returns404" \
+         "AgentSseControllerIT#lastEventIdHeader_connectionSucceeds" \
+         "AgentSseControllerIT#pingKeepalive_receivedViaSseStream" \
+         "SseSigningIT#deepTraceEvent_containsValidSignature"; do
+    echo "=== $t ==="

+done
+```
+
+Record for each: PASS or FAIL in isolation.
+
+- [ ] **Step 5.2: Run all SSE tests together in both class orders**
+
+```bash
+mvn -pl cameleer-server-app -am -Dit.test='AgentSseControllerIT,SseSigningIT' -Dtest='!*' -DfailIfNoTests=false -Dsurefire.failIfNoSpecifiedTests=false -Dsurefire.runOrder=alphabetical verify 2>&1 | tail -30
+mvn -pl cameleer-server-app -am -Dit.test='AgentSseControllerIT,SseSigningIT' -Dtest='!*' -DfailIfNoTests=false -Dsurefire.failIfNoSpecifiedTests=false -Dsurefire.runOrder=reversealphabetical verify 2>&1 | tail -30
+```
+
+Record: which tests fail in which order.
+
+- [ ] **Step 5.3: Investigate the `sseConnect_unknownAgent_returns404` case specifically**
+
+Read `AgentSseController.java:63-82`. Trace the control flow when:
+- JWT is valid for agent subject `X`
+- Path id is `unknown-sse-agent` (different from JWT subject)
+- `registryService.findById("unknown-sse-agent")` returns null
+- `jwtResult != null` — so auto-heal triggers, registers `unknown-sse-agent` with JWT's env+application, returns 200 with SSE stream
+
+Hypothesis: the test expects 404, but the controller's auto-heal path accepts the unknown agent because it only checks "JWT present", not "JWT subject matches path id". The 5s timeout on `statusFuture.get(...)` is because the 200 response opens an infinite SSE stream; `BodyHandlers.ofString()` waits for body completion that never comes.
+
+Confirm by inspecting `JwtAuthenticationFilter` and `JwtService.JwtValidationResult` to see whether `subject()` or an equivalent agent-id claim is available on the result. Then read a nearby controller that does verify subject-vs-path-id (e.g. `AgentRegistrationController.heartbeat` or `AgentCommandController`) for the accepted pattern.
+
+- [ ] **Step 5.4: Investigate the `awaitConnection(5000)` tests**
+
+For `lastEventIdHeader_connectionSucceeds`, `pingKeepalive_receivedViaSseStream`, `deepTraceEvent_containsValidSignature`: all register a fresh UUID-suffixed agent first, then open SSE with the JWT that was minted in `setUp()` for `test-agent-sse-it`. The JWT subject doesn't match the path id.
+
+If Step 5.3 finds the auto-heal bug, these tests may also benefit: when JWT subject ≠ path id, these tests currently rely on auto-heal too (since the path id was freshly registered through the `/register` endpoint, but the JWT they use in the SSE request is a *different* agent's JWT).
+
+Wait — re-check: `registerAgent` in the test uses `bootstrapHeaders()` (not JWT). It registers the agent directly. Then `openSseStream` uses `jwt` which is `securityHelper.registerTestAgent("test-agent-sse-it")` — a JWT for a different agent.
+
+So in these tests:
+- Path id: fresh UUID (registered via bootstrap)
+- JWT subject: "test-agent-sse-it"
+- `findById(uuid)` succeeds — agent exists
+- Auto-heal NOT triggered
+- Controller calls `connectionManager.connect(uuid)` — returns SseEmitter
+
+If this path works in isolation, why does it time out under full-class execution? Possibilities:
+- **Tomcat async thread pool** exhaustion. `SseEmitter(Long.MAX_VALUE)` holds a thread; prior tests' connections may not have closed before the pool fills
+- **SseConnectionManager state** leak — emitters from prior tests still in the map, competing
+- **The ping scheduler** (`@Scheduled(fixedDelayString = "${agent-registry.ping-interval-ms:15000}")`) — if an IOException on a stale emitter propagates
+
+Check Tomcat async config in `application.yml` and any `server.tomcat.*` settings. Default max-threads is 200 but async handling has separate limits.
+
+- [ ] **Step 5.5: Capture test output + logs**
+
+Run the failing tests with debug logging:
+
+```bash
+mvn -pl cameleer-server-app -am -Dit.test='AgentSseControllerIT' -Dtest='!*' -DfailIfNoTests=false -Dsurefire.failIfNoSpecifiedTests=false -Dlogging.level.com.cameleer=DEBUG -Dlogging.level.org.apache.catalina.core=DEBUG verify 2>&1 | tail -100
+```
+
+Look for:
+- `SseConnectionManager` log lines showing emitter count over time
+- "Replacing existing SSE connection" or "SSE connection timed out" patterns
+- Tomcat "async request timed out" warnings
+- Any `NOT_FOUND` being thrown that the client interprets as hanging
+
+- [ ] **Step 5.6: Write the diagnosis doc**
+
+Create `.planning/sse-flakiness-diagnosis.md` with sections:
+
+1. **Summary** — 1-2 sentences, named root cause (or "inconclusive")
+2. **Evidence** — commands run, output snippets, code references (file:line)
+3. **Hypothesis ladder** — auto-heal over-permissiveness, thread pool exhaustion, singleton state leak — with confidence level for each
+4. **Proposed fix** — if confident: specific changes to specific files. If inconclusive: say so, recommend parking with `@Disabled`.
+5. **Risk** — what could go wrong with the proposed fix.
+
+- [ ] **Step 5.7: Commit the diagnosis**
+
+```bash
+git add .planning/sse-flakiness-diagnosis.md
+git commit -m "$(cat <<'EOF'

+## Task 6 — SSE fix (branches based on Task 5 diagnosis)

+**Decision tree:**
+- **If Task 5 landed a confident root cause** → follow Task 6.A
+- **If Task 5 found auto-heal over-permissiveness as the (whole or partial) cause** → follow Task 6.B
+- **If Task 5 was inconclusive or the fix exceeds a 45-minute timebox** → follow Task 6.C (park)

+
+```bash
+gitnexus_impact({target: "<symbol_named_by_diagnosis>", direction: "upstream"})
+```
+
+- [ ] **Step 6.A.2: Apply the fix exactly as the diagnosis prescribes**
+
+Follow the "Proposed fix" section of `.planning/sse-flakiness-diagnosis.md` step-by-step. Do not adapt or extend — the diagnosis is the plan.

+
+### Task 6.B — Auto-heal guard (likely fix if Step 5.3 confirms)
+
+If diagnosis confirmed `AgentSseController` auto-heals regardless of JWT subject vs path id.
+
+- [ ] **Step 6.B.1: Impact analysis**
+
+```bash
+gitnexus_impact({target: "AgentSseController.events", direction: "upstream"})
+gitnexus_impact({target: "JwtService.JwtValidationResult", direction: "upstream"})
+```
+
+- [ ] **Step 6.B.2: Inspect JwtValidationResult for subject access**
+
+Read the `JwtValidationResult` class/record. Confirm it exposes the JWT subject (likely `.subject()` or similar accessor). Note the field name.
+
+- [ ] **Step 6.B.3: Add the guard to `AgentSseController.events`**
+
+Edit `cameleer-server-app/src/main/java/com/cameleer/server/app/controller/AgentSseController.java:63-76`.
+
+Replace the auto-heal block:
+
+```java
+AgentInfo agent = registryService.findById(id);
+if (agent == null) {
+    // Auto-heal: re-register agent from JWT claims after server restart
+    var jwtResult = (JwtService.JwtValidationResult) httpRequest.getAttribute(
+            JwtAuthenticationFilter.JWT_RESULT_ATTR);
+    if (jwtResult != null) {
+        String application = jwtResult.application() != null ? jwtResult.application() : "default";
+        String env = jwtResult.environment() != null ? jwtResult.environment() : "default";
+        registryService.register(id, id, application, env, "unknown", List.of(), Map.of());
+        log.info("Auto-registered agent {} (app={}, env={}) from SSE connect after server restart", id, application, env);
+    } else {
+        throw new ResponseStatusException(HttpStatus.NOT_FOUND, "Agent not found: " + id);
+    }

+
+with:
+
+```java
+AgentInfo agent = registryService.findById(id);
+if (agent == null) {
+    // Auto-heal re-registers an agent from JWT claims after server restart,
+    // but only when the JWT subject matches the path id. Otherwise a
+    // different agent could spoof any agentId in the URL.
+    var jwtResult = (JwtService.JwtValidationResult) httpRequest.getAttribute(
+            JwtAuthenticationFilter.JWT_RESULT_ATTR);
+    if (jwtResult != null && id.equals(jwtResult.subject())) {
+        String application = jwtResult.application() != null ? jwtResult.application() : "default";
+        String env = jwtResult.environment() != null ? jwtResult.environment() : "default";

+    } else {
+        throw new ResponseStatusException(HttpStatus.NOT_FOUND, "Agent not found: " + id);
+    }
+}
+```
+
+Adjust `jwtResult.subject()` to the actual accessor method from Step 6.B.2 (could be `.subject()`, `.instanceId()`, `.agentId()`, etc.).
+
+- [ ] **Step 6.B.4: Run `sseConnect_unknownAgent_returns404`**
+
+```bash
+mvn -pl cameleer-server-app -am -Dit.test='AgentSseControllerIT#sseConnect_unknownAgent_returns404' -Dtest='!*' -DfailIfNoTests=false -Dsurefire.failIfNoSpecifiedTests=false verify 2>&1 | tail -15
+```
+
+Expected: PASS. The controller now returns a synchronous 404 for the mismatched case.
+
+- [ ] **Step 6.B.5: Run the remaining 3 SSE tests**
+
+```bash
+mvn -pl cameleer-server-app -am -Dit.test='AgentSseControllerIT,SseSigningIT' -Dtest='!*' -DfailIfNoTests=false -Dsurefire.failIfNoSpecifiedTests=false verify 2>&1 | tail -30
+```
+
+If all 4 now pass → Task 6.B closed everything. If 3 still fail (the `awaitConnection` trio) → the auto-heal guard fixed the 404 case but the others have a separate root cause. Fall back to Task 6.A with narrower scope, or Task 6.C to park the residual.
+
+- [ ] **Step 6.B.6: Commit**
+
+```bash

+404 as 200 with an infinite empty stream (surface symptom: the parked

+
+If the 45-minute diagnosis timebox expires without a confident root cause, or Task 6.A/6.B leaves residual failures.
+
+- [ ] **Step 6.C.1: Annotate the failing tests**
+

+
+Expected: **0 failures**, plus either (a) all SSE tests passing if Task 6.A/6.B succeeded, or (b) 4 skipped if Task 6.C was taken.
+
+If any non-SSE test fails that previously passed: STOP. Root cause before pushing. Likely a regression from Task 1, 2, or 3 that escaped unit verification.

+- [ ] **Step 7.3: Push to main**
+
+```bash

+
+The user explicitly authorized pushing to main for this overnight run. If the remote rejects (non-fast-forward, auth), stop and report — do not `--force`.

+## Self-review (pre-execution)
+
+**Spec coverage:**
+- [x] Item 1 (CH timezone) → Task 1
+- [x] Item 2 (SSE flakiness) → Tasks 5 + 6 (diagnose-then-fix, autonomous variant without user checkpoint)
+- [x] Item 3 (scheduler property-key) → Task 2
+- [x] Item 4a (SearchIndexer cleanup) → Task 3
+- [x] Item 4b (TaggedExecution removal) → Task 4
+- [x] Execution order (Wave 1 parallelizable, Wave 2 sequential) → reflected in task numbering; Wave 1 tasks have no inter-task dependencies and can be executed in any order, Wave 2 (Tasks 5 → 6) is strictly sequential.
+
+**Placeholder scan:** Every step contains concrete commands, file paths, and code blocks. The one deferred decision (Task 6 branching based on diagnosis) is bounded — all three branches (A/B/C) are fully specified.
+
+**Type consistency:** `ingestionConfig` bean name consistent across Task 2 steps. `JwtValidationResult.subject()` access method flagged as "verify" in Step 6.B.2 — the actual accessor is confirmed during diagnosis, not guessed here.
+
+**Deviations from spec:** the spec called for a user checkpoint between SSE diagnosis and fix. This plan runs autonomously (user is asleep), so the checkpoint becomes a decision tree (Task 6.A/6.B/6.C) with explicit stop conditions.

+# IT Triage Follow-Ups — Design
+
+**Date:** 2026-04-21
+**Branch:** `main` (local, not pushed)
+**Starting HEAD:** `0f635576` (refactor(ingestion): drop dead legacy execution-ingestion path)
+**Context source:** `.planning/it-triage-report.md`
+
+## Goal
+
+Close the three tracks the IT triage report parked, plus two production-code cleanups flagged by the ExecutionController removal commit, so that `mvn -pl cameleer-server-app -am -Dit.test='!SchemaBootstrapIT' verify` returns **0 failures**.
+
+## Non-goals
+
+- Test-infrastructure hygiene (shared Testcontainers PG, shared agent registry across ITs). Report called these out as a separate concern — they stay deferred.
+- Rewriting tests to pass-by-weakening. Every assertion stays as strong or stronger than current.
+- New env vars, endpoints, DB tables, or schema columns beyond what's explicitly listed below.
+
+## Scope — 4 items
+
+1. **ClickHouseStatsStore timezone fix** — column-level `DateTime('UTC')` on `bucket`, greenfield CH (no migration)
+2. **SSE flakiness** — diagnose-then-fix with a user checkpoint between the two phases
+3. **MetricsFlushScheduler property-key fix** — bind via SpEL so `IngestionConfig` is the single source of truth
+4. **Dead-code cleanup** — `SearchIndexer.onExecutionUpdated` + `SearchIndexerStats` (possibly), and the unused `TaggedExecution` record
+
+## Item 1 — ClickHouseStatsStore timezone fix (8 failures)
+
+### Failing tests
+
+`ClickHouseStatsStoreIT` — 8 assertions that filter by a time window currently miss every row the MV bucketed because the filter literal is parsed in session TZ (CEST in the test env) while the `bucket` column stores UTC Unix timestamps.
+
+### Root cause
+
+`ClickHouseStatsStore.buildStatsSql` emits `lit(Instant)` which formats as `'yyyy-MM-dd HH:mm:ss'` with no timezone marker. ClickHouse parses that literal in the session timezone when comparing against the bare `DateTime`-typed `bucket` column. On a CEST CH host, `'2026-03-31 10:05:00'` becomes UTC `08:05:00` — off by the CEST offset — so the row inserted at `start_time = 10:00:00Z` (bucketed to `10:00:00` UTC) is excluded.
+
+The report's evidence: `toDateTime(bucket)` returned `12:00:00` for a row whose `start_time` was `10:00:00Z` — the stored UTC timestamp displayed in CEST.
+
+### Fix — column-level TZ
+
+Greenfield applies (pre-prod, no existing data to migrate). Changes:
+
+1. **`cameleer-server-app/src/main/resources/clickhouse/init.sql`**
+   - Change `bucket DateTime` → `bucket DateTime('UTC')` on every `stats_1m_*` target table
+   - Wrap `toStartOfMinute(...)` in `toDateTime(toStartOfMinute(...), 'UTC')` in every MV SELECT that produces a `bucket` value, so the MV output matches the column type
+   - Audit the whole file for any other `bucket`-typed columns or any other `DateTime`-typed column that participates in time-range filtering; if found, apply the same treatment
+
+2. **`ClickHouseStatsStore.buildStatsSql`**
+   - With the column now `DateTime('UTC')`, jOOQ's `lit(Instant)` literal should cast into UTC correctly. If it doesn't (quick verify in the failing ITs after the schema change), switch to an explicit `toDateTime('...', 'UTC')` literal.
+   - No behavioural change to the method signature or callers.
+
+### Blast radius
+
+- `gitnexus_impact({target: "buildStatsSql", direction: "upstream"})` before editing
+- `gitnexus_impact({target: "ClickHouseStatsStore", direction: "upstream"})` — identify all stats read paths
+- Every MV definition touched → any dashboard or API reading `stats_1m_*` sees the same corrected values
+
+### Verification
+
+The 8 failing ITs in `ClickHouseStatsStoreIT` are the regression net. No new tests. After the fix, all 8 go green without touching the test code or container TZ env.
+
+### Commits
+
+1 commit: `fix(stats): store bucket as DateTime('UTC') so reads don't depend on CH session TZ`
+
+## Item 2 — SSE flakiness (4 failures, diagnose-then-fix)
+
+### Failing tests
+
+- `AgentSseControllerIT.sseConnect_unknownAgent_returns404` — 5s timeout on what should be a synchronous 404
+- `AgentSseControllerIT.lastEventIdHeader_connectionSucceeds` — `stream.awaitConnection(5000)` returns false
+- `AgentSseControllerIT.pingKeepalive_receivedViaSseStream` — keepalive never observed in stream snapshot
+- `SseSigningIT.deepTraceEvent_containsValidSignature` — `awaitConnection` pattern, never sees signed event
+
+Sibling test `SseSigningIT.configUpdateEvent_containsValidEd25519Signature` passes in isolation — strong signal of order-dependent flakiness, not a protocol break.
+
+### Phase 2a — Diagnosis
+
+One commit, markdown-only: `docs(debug): SSE flakiness root-cause analysis`.
+
+Steps:
+
+1. **Baseline in isolation.** Run each failing test solo (`-Dit.test=AgentSseControllerIT#sseConnect_unknownAgent_returns404` etc.) to confirm it passes alone. Record.
+2. **Bisect test order.** Run the full IT suite with `-Dsurefire.runOrder=alphabetical` and `-Dsurefire.runOrder=reversealphabetical`. Identify which prior IT class poisons the state.
+3. **Inspect shared singletons.** Read `SseConnectionManager`, `AgentInstanceRegistry`, the Tomcat async thread pool config, any singleton HTTP client used by the `SseTestClient` harness. Look for state that persists across Spring context reuse when `@DirtiesContext` isn't applied.
+4. **Inspect `sseConnect_unknownAgent_returns404` specifically.** A synchronous 404 that hangs 5s is suspicious on its own. Likely cause: the controller opens the `SseEmitter` *before* validating agent existence, so the test client sees an open stream and the `CompletableFuture` waits on body data that never arrives. That would be a controller bug — a real finding, not a test problem.
+5. **Write `.planning/sse-flakiness-diagnosis.md`** with: named root cause, evidence (test output, log excerpts, code references), proposed fix, risk. Commit only this file.
+
+### CHECKPOINT
+
+Stop and present the diagnosis to the user. Do not proceed to Phase 2b until approved — the fix shape depends entirely on what the diagnosis finds, and we can't responsibly plan it up front.
+
+### Phase 2b — Fix (1–2 commits, shape TBD)
+
+Likely shapes (to be locked by diagnosis):
+
+- **If shared-singleton state poisoning** → add `@DirtiesContext(classMode = BEFORE_CLASS)` on the affected IT classes, or add a proper reset bean (e.g. `SseConnectionManager.clear()` called from a test-only `@Component`).
+- **If `sseConnect_unknownAgent_returns404` controller bug** → reorder `AgentSseController` to call `agentRegistry.lookup()` *before* creating the `SseEmitter`; return a synchronous `ResponseEntity.notFound()` when the agent is unknown.
+- **If thread-pool exhaustion** → explicit bounded async pool with sizing tied to test count.
+
+Any fix must be accompanied by a `.claude/rules/app-classes.md` update if controller behaviour changes.
+
+### Blast radius
+
+Depends on diagnosis. `gitnexus_impact` on whatever symbols the diagnosis names, before the fix commit lands.
+
+### Verification
+
+The 4 failing ITs are the regression net. Fix lands only once all 4 go green and the sibling passing tests stay green.
+
+### Commits
+
+1 diagnosis commit + 1–2 fix commits.
+
+## Item 3 — MetricsFlushScheduler property-key fix
+
+### Root cause
+
+`IngestionConfig` is `@ConfigurationProperties("cameleer.server.ingestion")`. `MetricsFlushScheduler.@Scheduled(fixedRateString = "${ingestion.flush-interval-ms:1000}")` uses a key with no `cameleer.server.` prefix. The YAML key `cameleer.server.ingestion.flush-interval-ms` is never resolved by the scheduler; the `:1000` fallback is always used. Prod config of flush interval is silently ignored.
+
+### Fix
+
+Bind via SpEL so `IngestionConfig` is the single source of truth and the `:1000` default doesn't get duplicated between YAML and `@Scheduled`:
+
+```java
+@Scheduled(fixedRateString = "#{@ingestionConfig.flushIntervalMs}")
+```
+
+Requires `IngestionConfig` to be a named bean (usually via `@ConfigurationProperties` + `@EnableConfigurationProperties` — verify it is, or ensure the bean name is `ingestionConfig` / whatever SpEL resolves). If the default on `IngestionConfig.flushIntervalMs` field isn't already `1000`, keep it there — it's the single place the default is now defined.
+
+### Blast radius
+
+- `gitnexus_impact({target: "IngestionConfig.getFlushIntervalMs", direction: "upstream"})` — confirm no other `@Scheduled` strings depend on the old unprefixed key
+- `gitnexus_impact({target: "MetricsFlushScheduler", direction: "upstream"})` — confirm no test depends on the old placeholder string
+
+### Verification
+
+No new test. The prod bug is "silent config not honoured" — testing `@Scheduled` placeholder resolution is framework plumbing and not worth a test. Manual verification: set `cameleer.server.ingestion.flush-interval-ms: 250` in `application.yml` and confirm logs show 250ms flush cadence rather than 1s.
+
+### Commits
+
+1 commit: `fix(metrics): MetricsFlushScheduler honour ingestion config flush interval`.
+
+## Item 4 — Dead-code cleanup (2 commits)
+
+Flagged in `0f635576`'s commit message as follow-on cleanups from the ExecutionController removal.
+
+### 4a — SearchIndexer.onExecutionUpdated (+ possibly SearchIndexerStats)
+
+After the ExecutionController removal, `SearchIndexer.onExecutionUpdated` is subscribed to `ExecutionUpdatedEvent`, but nothing publishes that event anymore. The method can never fire. `SearchIndexerStats` is still referenced by `ClickHouseAdminController`.
+
+Decide based on what `SearchIndexerStats` tracks once read:
+
+- **(a)** If `SearchIndexerStats` tracks only dead signals → delete the whole subsystem (listener + stats class + admin controller exposure + UI consumer if any)
+- **(b)** If it still tracks live signals (e.g. search index build time) → delete just the listener method and keep the stats class
+
+Approach: read `SearchIndexerStats` and `ClickHouseAdminController` before committing to a shape; pick (a) or (b) accordingly; note the decision in the commit message.
+
+Blast radius: `gitnexus_impact({target: "onExecutionUpdated"})` and `gitnexus_impact({target: "SearchIndexerStats"})`.
+
+Rule update: `.claude/rules/core-classes.md`.
+
+### 4b — TaggedExecution record
+
+Commit message on `0f635576` says no remaining callers. Verify with `gitnexus_context({name: "TaggedExecution"})` before deleting — if anything surprises us (e.g. a test file referencing it), fold that into the delete commit.
+
+Blast radius: `gitnexus_impact({target: "TaggedExecution"})` — expect empty upstream.
+
+Rule update: `.claude/rules/core-classes.md` (it's explicitly listed there as a leftover).
+
+### Commits
+
+2 commits, one per piece:
+- `refactor(search): drop dead SearchIndexer.onExecutionUpdated listener` (plus stats cleanup if applicable)
+- `refactor(model): remove unused TaggedExecution record`
+
+## Execution order
+
+**Wave 1 — parallelizable, no inter-dependencies:**
+- Item 1 (CH timezone)
+- Item 3 (scheduler SpEL)
+- Item 4a (SearchIndexer)
+- Item 4b (TaggedExecution)
+
+**Wave 2 — sequential with user checkpoint:**
+- Item 2a (SSE diagnosis)
+- **CHECKPOINT** — user reviews diagnosis
+- Item 2b (SSE fix)
+
+Total commits: 5–6 on local `main`, not pushed (same convention as the triage report already established).
+
+## Verification — final

+- **Before each commit:** `gitnexus_detect_changes({scope: "staged"})` — verify scope matches expectation
+- **After each commit:** GitNexus index re-runs via PostToolUse hook per CLAUDE.md
+- **`.claude/rules/` updates** are part of the same commit as the class-level change, not a separate task
+- **No new env vars, endpoints, tables, or columns** beyond what's explicitly listed in this spec
+- **No tests rewritten to pass-by-weakening.** Every assertion change is accompanied by a comment capturing the contract it now expresses
+
+## Risks
+
+- **Item 2 diagnosis finds nothing conclusive.** Mitigation: the diagnosis commit documents what was ruled out, user decides whether to continue investigating or park with `@Disabled` + a GH issue pointer. No code-side workaround (sleeps, retries) per report's explicit direction.
+- **Item 1 MV recreation drops existing local dev data.** Greenfield means this is acceptable. Local devs re-run their smoke scenarios. No prod impact since there is no prod yet.
+- **Item 3 SpEL bean name resolution fails.** `IngestionConfig` might not be registered with the exact bean name `ingestionConfig`. Mitigation: verify bean name via `ApplicationContext.getBeanNamesForType(IngestionConfig.class)` in a quick smoke before committing; if the name differs, use the actual name in SpEL.
+- **Item 4a decision is harder than expected.** If `SearchIndexerStats` has a live UI consumer the cleanup scope changes. Mitigation: read first, commit to (a) or (b) with a clear note.
