+# Phase 18 Plan 03: Campaign Read API (List + Detail) Summary
+
+**Two new GET routes — `/api/phishing/campaigns` (paginated camelCase list) and `/api/phishing/campaigns/{id}` (nested detail with linked reports/messages/indicators/classifications) — both gated by `requirePermission('phishing','read')`.**
+
+## Performance
+
+- **Duration:** ~20 min
+- **Started:** 2026-07-15T23:15Z (approx)
+- **Completed:** 2026-07-15T23:31Z
+- **Tasks:** 2/2 completed
+- **Files modified:** 2 (both created)
+
+## Accomplishments
+- `app/api/phishing/campaigns/route.ts` — paginated `GET` returning `{ items, total, limit, offset }` in camelCase (id, campaignKey, groupMethod, firstSeenAt, lastSeenAt, reportCount, status, createdAt). `limit` clamped to `[1,200]` (default 50), `offset` clamped to `>= 0` (default 0), optional `status` filter bound via a `$n` placeholder (never string-interpolated).
+- `app/api/phishing/campaigns/[id]/route.ts` — `GET` returning one campaign with nested `reports[]` (+ `requesterEmail` via `contacts` join), `messages[]` (+ `subject` via `headers->>'subject'`), `indicators[]`, and `classifications[]`, all in camelCase. UUID-validates the path param (400 on malformed id before any query), 404 when the campaign is absent. Children are bulk-fetched via `= ANY($1::uuid[])` keyed by the parent id array (device-link-conflicts pattern), with an empty-array short-circuit so no query runs when there are zero reports/messages.
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: GET /api/phishing/campaigns paginated list** - `c852cfe` (feat)
+2. **Task 2: GET /api/phishing/campaigns/[id] nested detail** - `959907d` (feat)
+
+**Plan metadata:** committed alongside this SUMMARY (final commit in this plan's history)
+
+## Files Created/Modified
+- `app/api/phishing/campaigns/route.ts` - `GET` handler: requirePermission gate, clamp limit/offset, optional parameterized status filter, COUNT(*) total, camelCase `.map()`
+- `app/api/phishing/campaigns/[id]/route.ts` - `GET` handler: requirePermission gate, UUID regex validation (400), parent campaign lookup (404 if absent), bulk-fetch reports (+ contacts join for requesterEmail) / messages (+ headers->>'subject') / indicators / classifications, camelCase nested assembly
+
+## Decisions Made
+- Followed 18-PATTERNS.md section 4/5 code shapes essentially verbatim — no deviation in query structure or response shape from the pattern map's "Exact shape to replicate" blocks.
+- Confirmed `messages` has no `subject` column (checked `migrations/097_phishing_triage_schema.sql` directly) before writing the query, per the plan's explicit warning that a naive `SELECT subject` would fail — used `headers->>'subject' AS subject` instead.
+- Both routes wrap all Postgres work in try/catch returning 500 `{ error, message }` on unexpected failure, matching `device-link-conflicts/route.ts`'s error-handling convention (not shown in the pattern map's illustrative snippets, but required by CLAUDE.md's API route conventions and consistent with Task 1's stated acceptance criteria).
+
+## Deviations from Plan
+
+**1. [Manual verification not performed against a live server]**
+- **Found during:** Task 1 and Task 2 verification step
+- **Issue:** Both tasks' `<verify>` blocks specify a `<human-check>` step (curl against `localhost:3100` with an admin session cookie to confirm 200/401/400/404 responses). The dev server currently listening on port 3100 in this sandbox is a long-running Next.js process bound to the main repository checkout (`next-server`, running since before this session started), not this git worktree — it does not reflect the two new route files created here. Restarting or repointing that shared server risked disrupting other concurrent worktree agents in the same wave.
+- **Resolution:** Performed the automated verification (`npx tsc --noEmit --pretty`, exit 0, both files) and re-derived every acceptance criterion via targeted `grep` (requirePermission call sites, `$n` placeholder, `Math.min` clamp, `ANY($1::uuid[])` bulk-fetch, UUID regex, `requester_contact_id` join, `headers->>'subject'`) — all confirmed present. The live curl-based 200/401/400/404 check is deferred to the orchestrator's post-wave verification pass (or a future manual QA pass), since it requires a server instance actually running this worktree's code plus a real campaign UUID and an authenticated session cookie, neither of which are safely producible from this isolated worktree without touching shared infrastructure.
+- **Files modified:** none (documentation-only deviation, no code change)
+- **Impact:** Both routes are believed correct per code review against the pattern map and the type checker; the manual HTTP-level check is the one open item, not a code defect.
+
+---
+
+**Total deviations:** 1 (verification method substitution, no code impact)
+**Impact on plan:** No scope creep, no code changes beyond the plan's spec. The only deviation is in how the manual verification step was satisfied (static analysis + grep instead of live curl), due to the shared-server constraint of the worktree execution model.
+
+## Issues Encountered
+None beyond the verification-method note above.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Both campaign read routes are live and ready for Phase 19 (classification) and Phase 20 (remediation/approval) to build write-path routes alongside them under the same `/api/phishing/*` namespace and `requirePermission('phishing', ...)` convention.
+- The detail route's `classifications[]` array is wired to query the `classifications` table now — Phase 19 can start writing rows to it with zero changes needed on this route.
+- Recommended follow-up (not blocking): once a real campaign exists in a running environment, a human or the phase verifier should do the one live curl pass (200/401/400/404) that this plan's `<human-check>` originally called for.
+
+---
+*Phase: 18-campaign-grouping-phishing-analysis-api*
+*Completed: 2026-07-15*
+
+## Self-Check: PASSED
+
+Both created files confirmed present on disk; both task commit hashes (`c852cfe`, `959907d`) confirmed present in git log.
