  - "The plan's History tab spec calls for 'a zone-wide view when no record is selected', but the only history endpoint implemented in plan 24-05 is per-record (GET .../records/{recordId}/history) — there is no zone-wide history route and this plan's files_modified does not authorize adding one. Implemented instead: History tab shows an EmptyState prompting the operator to pick a record's History action on the Records tab; once selected, the tab shows that record's full ledger with a Clear control to return to the prompt."
  - "GET /api/route53/sync never actually returns 503 for the unconfigured case in the current plan-24-05 implementation (only the POST trigger and the CRUD write routes do) — the page still checks for a 503 on the GET response per the plan's literal acceptance criteria (defensive / forward-compatible), and separately surfaces a 503 from the POST Sync Now action via a toast + the same unconfigured empty-state."

# Phase 24 Plan 7: Route 53 Admin Detail Page + Record Editor Summary

Built the `/admin/sync/route53` four-tab detail page and the create/edit/delete record dialog
that drive the plan 24-05 CRUD routes, then ran the nine-step live AWS end-to-end checkpoint
against the real `wulfconsulting.com` hosted zone. All nine steps passed. One real bug was
found and fixed during the checkpoint (see "Checkpoint-Discovered Bug" below).

## Performance

- **Duration:** ~55 min (Tasks 1-2 only)
- **Tasks:** 2 of 3 completed; Task 3 blocked awaiting human verification
- **Files modified:** 2 created, 1 doc updated

## Accomplishments

- `/admin/sync/route53` renders Zones / Records / History / Schedule tabs following the
  `veeam`/`pax8` sync-detail-page shape, with a Sync Now trigger (bounded 3s/20-poll loop),
  a status line (zone/record/history-row counts + last sync status), and a graceful
  unconfigured empty-state.
- Records tab actions cell gates on the D-01 writable-type allowlist (`A`/`AAAA`/`CNAME`/
  `MX`/`TXT`/`SRV`); NS/SOA rows render a muted "Read-only" label with an explanatory
  `title`, with the real 400 gate remaining server-side (plan 24-05).
- History tab renders `pulse_crud` vs `sync_detected_drift` with visually distinct
  `StatusBadge` tones (D-06), plus change-action (create/update/delete) and actor columns.
- `RecordEditorDialog` (create/edit) and `RecordDeleteConfirm` (single misclick-guard,
  immediate delete, D-03) both wired to the plan 24-05 write routes, with the submit/delete
  controls disabled while their own request is in flight (T-24-20) and server 400/409/502
  messages rendered inline without closing the dialog.
- Confirmed the dev server is live on port 3100 and `/admin/sync/route53` correctly
  redirects an unauthenticated request to `/auth/sign-in` (middleware working as expected)
  ahead of handing off the checkpoint.

## Task Commits

1. **Task 1: Zones, records, and history page shell** - `b3048be` (feat)
2. **Task 2: Record editor dialog with create, edit, and immediate delete** - `fadfcb8` (feat)
3. **Task 3: End-to-end phase verification** - `31eb5e0` (docs, partial handoff) → checkpoint
   resolved live by the developer; TXT-quoting bug fixed in `4da5664`
   (`fix(24-05): quote TXT record values per RFC 1035 character-string format`)

**Plan metadata:** this commit (docs: finalize checkpoint results, mark plan complete)

## Files Created/Modified

- `app/admin/sync/route53/page.tsx` — four-tab detail page (789 lines)
- `components/admin/route53/record-editor-dialog.tsx` — `RecordEditorDialog` + `RecordDeleteConfirm` (370 lines)
- `.planning/phases/24-aws-route-53-dns-sync-track-changes-crud-operations-full-aud/24-VALIDATION.md` — marked 24-07-T1/24-07-T2 rows green; 24-07-T3 (the checkpoint) left pending

## Decisions Made

See `key-decisions` in frontmatter: (1) API responses are `{ items: [...] }` envelopes, not
bare arrays as the plan's interfaces block stated — followed the actual plan-24-05 route
implementations; (2) no zone-wide history endpoint exists, so the History tab requires a
record selection first rather than showing an unfiltered zone view; (3) the unconfigured-503
check is implemented on the sync-status GET per the plan's literal spec even though the
current route never emits it, and is backed up by handling a 503 from the POST trigger.

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 1 - Bug] Grep-checked acceptance criteria false-positived on doc-comment prose**
- **Found during:** Task 1 verification (`grep -c dangerouslySetInnerHTML` / `grep -c swr\|react-query`)
- **Issue:** the file-header doc comment explained the security posture by naming the literal
  strings the acceptance grep checks are zero occurrences of (e.g. "no dangerouslySetInnerHTML",
  "no SWR/react-query"), which made both grep counts 1 instead of 0 even though no actual
  usage exists — the same false-positive pattern documented in 24-05's SUMMARY.
- **Fix:** reworded the two affected doc-comment lines to describe the same guarantee without
  the literal grepped substrings ("no raw-HTML injection helper", "no client-side data-fetching
  library").
- **Files modified:** `app/admin/sync/route53/page.tsx`
- **Verification:** `grep -c dangerouslySetInnerHTML` and `grep -c "swr\|react-query\|useSWR"` both return 0; `npx tsc --noEmit --pretty` and `npm run build` both clean after the edit.
- **Committed in:** `b3048be` (part of Task 1 commit — caught before commit, not a follow-up fix)

### Out-of-Scope Discovery (logged, not fixed)

None beyond what's already documented in earlier phase-24 plans' `deferred-items.md`.

## Checkpoint Status: RESOLVED — all nine steps passed

Task 3's live, 9-step verification was run by the developer against the real
`wulfconsulting.com` hosted zone (zone id `Z02608081TM3M5T9ERS5J`) and a Pulse `super-admin`
session (`lorentz@wulfconsulting.com`), plus a `user`-role session
(`colleen@wulfconsulting.com`) for step 7. The orchestrator ran the curl/psql commands on the
developer's behalf per the plan's automation-first checkpoint protocol; AWS-console and
browser actions were performed by the developer directly. Observed outcomes:

1. **Sync (SC-1)** — ✅ AWS Route 53 tile present, Sync Now produced non-zero zone/record counts.
2. **Create (SC-2/SC-3/SC-4)** — ✅ passed on retry, after a real bug was found and fixed (see
   "Checkpoint-Discovered Bug" below). First attempt failed with AWS's
   `InvalidCharacterString` error; after the fix, create succeeded with a `create`/`pulse_crud`
   history row.
3. **Update** — ✅ confirmed.
4. **Delete (D-03)** — ✅ single confirmation, immediate execution, confirmed gone from AWS.
5. **Audit completeness (SC-3/D-07)** — ✅ `route53_audit_log` query confirmed 3 `committed`
   rows (create/update/delete) for `pulse-phase24-test.wulfconsulting.com.`, all attributed to
   `lorentz@wulfconsulting.com`. `aws_change_status` read `PENDING` on all three rows rather
   than `INSYNC` — expected, not a defect: `pollChangeStatus` is intentionally bounded to a
   15-second budget (per `route53-change-submit.ts`'s design, to avoid blocking the request
   handler on full DNS propagation) and returned before AWS finished propagating; the write
   itself was already confirmed `committed` independently of propagation status.
6. **Failure logging (D-07/T-24-01)** — ✅ NS write via curl → `400`
   (`"Record type NS is not writable from Pulse — NS and SOA are zone-delegation records (D-01)"`).
   Genuine AWS-side rejection (apex CNAME on `wulfconsulting.com.`) → `502` with a `failed`
   `route53_audit_log` row and a clean, sanitized `error_message` (verified directly via
   `psql` — no AWS account id/ARN/key id present, matching `sanitizeAwsError`'s contract).
7. **Auth gating (D-04/T-24-02)** — ✅ the `user`-role session got `403` on the create attempt
   (`"Forbidden - Admin access required"`) while `GET /api/route53/zones` still returned `200`
   for that same session. The `super-admin` session's equivalent write succeeded normally.
8. **Drift detection (D-06)** — ✅ confirmed by the developer: hand-editing a record in the AWS
   console then Sync Now produced a `sync_detected_drift` history row with a null actor.
9. **Health check (D-12/SC-6)** — ✅ confirmed by the developer: live status row present;
   toggling Route 53 off/on at `/admin/integrations` showed the `disabled` status while a
   manual sync still succeeded (D-10). The developer noted the whole `/admin/integrations`
   page felt slow during this step — investigated and determined **not** specific to Route 53
   (see "Deferred: /admin/integrations page latency" below).

**Resume signal:** developer confirmed all nine steps behave as expected after the fix below.

## Checkpoint-Discovered Bug: TXT records rejected by AWS (fixed)

Step 2 (create) initially failed with:
```
Invalid Resource Record: 'FATAL problem: InvalidCharacterString (Value should be enclosed in
quotation marks) encountered with 'phase24-verification'', RRSet with DNS name
pulse-phase24-test. is not permitted in zone wulfconsulting.com.
```

**Root cause:** `lib/services/route53-change-submit.ts`'s `buildChangeBatch` passed TXT record
values to AWS unquoted. Route 53 requires TXT (and SPF) record RDATA in RFC 1035
character-string format — each value must be wrapped in double quotes, with segments over 255
characters split into multiple quoted, space-joined segments. Plan 24-05's `buildChangeBatch`
and its test suite covered A/AAAA/CNAME/MX/SRV/TXT construction generically but never exercised
this AWS-side format requirement — the gap was invisible to unit tests since `buildChangeBatch`
is pure/local and the tests never hit a real AWS endpoint.

**Fix (commit `4da5664`):** added `formatTxtValue()`/`formatResourceRecordValue()` to
`route53-change-submit.ts` — TXT values are now escaped (backslashes and double quotes) and
wrapped in double-quoted segments (≤255 chars each); all other writable types pass through
unchanged. Four new regression tests added to `route53-change-submit.test.ts` (plain-value
quoting, escaping, 255-char segment splitting, non-TXT pass-through) — all pass. Full test
suite, `tsc`, and `npm run build` all green after the fix; `pulse-app` rebuilt and restarted
with the fix before the checkpoint retry succeeded.

## Deferred: `/admin/integrations` page latency

Developer reported the whole `/admin/integrations` page (not specifically the Route 53
row/toggle) felt slow during checkpoint step 9. `checkRoute53()`'s own live checks (AWS
`ListHostedZonesCommand` + the D-12 NS-delegation comparison, bounded to 5 concurrent workers
with a 5s-per-zone DNS timeout, ~3 zones in this account) are inherently bounded to a few
seconds — not the likely source. `checkIntegrationHealth()` fans out via `Promise.all` across
every configured integration, so one other integration's `liveCheck()` probe lacking a tight
timeout would drag down the whole aggregate. Not investigated further or fixed — pre-existing,
out of scope for Phase 24. Logged in `deferred-items.md`.

**24-VALIDATION.md status:** all three Manual-Only Verifications rows (write-route auth
gating, live AWS round-trip, D-10 display-only disable) updated with observed outcomes.
Status table's 24-07-T3 row marked ✅ green.

## Self-Check: PASSED

- FOUND: app/admin/sync/route53/page.tsx
- FOUND: components/admin/route53/record-editor-dialog.tsx
- Commit `b3048be` present in `git log`
- Commit `fadfcb8` present in `git log`

## Threat Flags

None beyond what's already covered by this plan's own `<threat_model>` (T-24-25, T-24-02,
T-24-20, T-24-01, T-24-26) — all addressed as designed in "Accomplishments" above. No new
network endpoints, auth paths, or schema changes were introduced; both new files only call
the already-existing `/api/route53/*` surface from plan 24-05.
