docs(24-01): create partial SUMMARY, checkpoint pending

Tasks 1-2 complete (AWS SDK + schema migration, types + credential factory).
Task 3 is a blocking human-verify checkpoint requiring BWS/AWS credential
confirmation and live docker/DNS-egress verification — not fabricated, not
run unilaterally. Execution stops here pending developer response.

+# Phase 24 Plan 1: Route 53 Foundation Summary
+
+Installed the official AWS Route 53 SDK client, created the dedicated four-table
+Postgres schema (mirror tables + change-history ledger + audit ledger), defined
+shared camelCase TypeScript types, and built the `route53-factory.ts` credential
+factory following the exact `is<Name>Configured()` + singleton shape every other
+Pulse integration uses — TDD RED/GREEN cycle, 7/7 tests passing.
+
+## What Was Built
+
+**Task 1 — AWS SDK + migration:**
+- `npm install @aws-sdk/client-route-53` (official `aws/aws-sdk-js-v3` package, confirmed `[OK]` in 24-RESEARCH.md's package legitimacy audit)
+- `migrations/102_route53_tables.sql` — four tables:
+  - `route53_zones` (mirror, PK = AWS hosted zone id with `/hostedzone/` prefix stripped)
+  - `route53_records` (mirror, PK = composite `record_key` string since Route 53 recordsets have no native id)
+  - `route53_record_history` (D-06 append-only change ledger, `source` CHECK constrained to `pulse_crud`/`sync_detected_drift`)
+  - `route53_audit_log` (D-03/D-07 append-only attempt log including failures, `status` CHECK constrained to `pending`/`committed`/`failed`, `zone_id` deliberately not an FK)
+  - Seed row `INSERT INTO integration_settings (key, disabled) VALUES ('route53', false)` (D-10, display-only toggle — extends the existing seed list rather than editing the committed `081_integration_settings.sql`)
+- Migration was **not yet applied to a live database** in this worktree (no `pulse-postgres` container reachable from here) — flagged as a deployment follow-up. The committed file is the source of truth for new installs.
+
+**Task 2 — Types + factory (TDD):**
+- RED: `lib/services/route53-factory.test.ts` written first, confirmed failing (module didn't exist)
+- GREEN: `lib/types/route53.ts` (camelCase interfaces/unions per the plan's `<interfaces>` contract) + `lib/services/route53-factory.ts` (singleton factory, no explicit `credentials:` option passed to `Route53Client` — relies on the AWS SDK default credential chain reading `AWS_ACCESS_KEY_ID`/`AWS_SECRET_ACCESS_KEY` from `process.env`, per 24-RESEARCH.md Pitfall 1)
+- `CLAUDE.md` integration table updated with the `AWS Route 53` / `AWS_*` exception row
+- 7/7 test assertions pass; `npx tsc --noEmit --pretty` exits clean
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+None — plan executed exactly as written for Tasks 1-2.
+
+### Environment Note (not a deviation, a pre-condition)
+
+This worktree's branch (`worktree-agent-aa690b9b15c5b0f8e`) was created before the
+phase 24 planning commits landed on `master` — it had zero unique commits and was
+purely 14 commits behind. Fast-forwarded (`git merge --ff-only master`) to pick up
+`24-01-PLAN.md` and related planning docs before execution could start. This was a
+clean fast-forward (no merge, no conflicts, nothing discarded).
+
+### Out-of-Scope Discovery (logged, not fixed)
+
+`npm test` (full suite, run as part of Task 2 verification) surfaced 2 pre-existing
+failures in `lib/services/analyzer/itglue-search.test.ts`, unrelated to this plan —
+neither that file nor `itglue-search.ts` were touched by Tasks 1-2. Logged to this
+phase's `deferred-items.md` per the scope boundary rule rather than fixed.
+
+## Checkpoint Status: PENDING (Task 3 not yet answered)
+
+Task 3 is a `checkpoint:human-verify` gate requiring the developer to confirm, from
+outside this worktree/sandbox:
+
+1. **BWS secret key names** — whether Bitwarden Secrets Manager's project (referenced
+   by `BWS_PROJECT_ID`) stores AWS credentials under the literal keys
+   `AWS_ACCESS_KEY_ID` / `AWS_SECRET_ACCESS_KEY` / `AWS_REGION`.
+2. **Credentials reach the container** — `docker exec pulse-app sh -lc 'echo "id=${AWS_ACCESS_KEY_ID:+SET} secret=${AWS_SECRET_ACCESS_KEY:+SET} region=${AWS_REGION:-unset}"'`
+3. **Outbound DNS egress** to 1.1.1.1/8.8.8.8 on UDP/53 from inside the container —
+   drives plan 24-04's implementation choice (Node `dns` module vs. DoH-over-HTTPS fallback).
+4. **IAM scope** — confirm the IAM principal is scoped to the five Route 53 actions only.
+
+This executor did not fabricate these answers or run live/destructive docker commands
+unilaterally, per explicit orchestrator instruction. Execution stops here; a
+continuation agent should resume at Task 3 once the developer responds.
