# Phase 1 Completion and Phase 2 Hard Gate

Phase 2 production implementation is blocked until this report is fully populated and approved by named Timetabler and Resource Booking service owners.

Current staging status: **Phase 1 continuous synchronization and coordinated E2E-01–E2E-13 PASS; overall Phase 1 completion and Phase 2 entry remain BLOCKED.** LOAD-01–LOAD-08 and the remaining approval/OpenSpec gates are incomplete. Reverse delivery remains disabled in both services.

## Continuous staging synchronization evidence (2026-08-07)

| Evidence | Verified result |
| --- | --- |
| Timetabler provider build | `origin/dev` `a531af1cf74e0d7e10445c0799e71be4816f8ace` supplied the activated Phase 1 publisher and canonical v2 source transactions |
| Architecture | One composite Kafka record per committed Timetabler source transaction on `timetabler.activity.events`; one partition preserves total order; Timetabler is authoritative and Resource Booking owns transformation/application |
| Shared staging host | Both services reported SHA-256 `c4994701ae04f9730c97104bedbe35a3e03466cf5768d09ee86cc59f2a123b4b`; dedicated sync endpoints use `127.0.0.1:9092` and Resource Booking's general Kafka endpoint was not overwritten |
| Topic provision | Resource Booking run [31112744065](https://github.com/Mayvins/resource-booking-be/actions/runs/31112744065): one broker, one partition, RF1 (staging-only for the single broker), 30-day delete retention, unclean leader election false, and bounded message size |
| Broker/group readiness | Resource Booking diagnostic run [31113864019](https://github.com/Mayvins/resource-booking-be/actions/runs/31113864019) passed; Timetabler diagnostic run [31112956666](https://github.com/Mayvins/timetabler-be/actions/runs/31112956666) confirmed the topic while publication was still off |
| Consumer activation | Resource Booking `ea01f2a` constructs `AIOKafkaConsumer` inside the `asyncio.run()` event loop; bounded probe [31114460845](https://github.com/Mayvins/resource-booking-be/actions/runs/31114460845) and activation [31114549544](https://github.com/Mayvins/resource-booking-be/actions/runs/31114549544) passed |
| Fail-closed cutover | Historical sequences 1–42 caused run [31114759974](https://github.com/Mayvins/resource-booking-be/actions/runs/31114759974) to quarantine one historical-cutover record and automatically disable ingestion; no conflict was accepted and Timetabler publication was disabled for recovery |
| Fixed-watermark recovery | Reconciliation [31115466339](https://github.com/Mayvins/resource-booking-be/actions/runs/31115466339) scanned 1,794 resources and 46 activities with zero drift, repair, unresolved items, or quarantine; recovery [31115622893](https://github.com/Mayvins/resource-booking-be/actions/runs/31115622893) was healthy at watermark 42, lag zero, and no quarantine/DLQ/mirror-only violation |
| Live post-cutover canary | Nineteen committed Timetabler projection transactions advanced source sequence 42→61; activation [31115855194](https://github.com/Mayvins/timetabler-be/actions/runs/31115855194) published through 61 with healthy liveness and zero dead letters; Resource Booking validation [31115992828](https://github.com/Mayvins/resource-booking-be/actions/runs/31115992828) consumed all 19 at watermark 61 with zero lag/gap/quarantine/DLQ/mirror-only violation/projection backlog and readiness `ready/running` |
| Final safe direction | Timetabler capture/publish/approval true, transport Kafka, reverse false; Resource Booking Phase 1 ingestion true, repair false, reverse false |

This evidence closes the continuous staging transport slice. The later coordinated E2E evidence below also confirms rollback/resume and completes OpenSpec tasks 10.1–10.13. Task 9.1 remains conservatively open because its full metrics and write-path-parity clause is not established by these runs; tasks 9.2, 9.3, and 9.5–9.7 also remain open.

## Coordinated E2E-01–E2E-13 PASS (2026-08-07)

Run ID: `phase1-e2e-20260807-01`.

| Stage | Timetabler run | Resource Booking run | Accepted result |
| --- | --- | --- | --- |
| Functional (`E2E-01`–`E2E-08`) | [31184585822](https://github.com/Mayvins/timetabler-be/actions/runs/31184585822) | [31193533830](https://github.com/Mayvins/resource-booking-be/actions/runs/31193533830) | Supported resource lifecycle, engine, Pre-Schedule/final-drop, booking, replacement, lifecycle, and manual constraint-break scenarios passed with atomic source/application evidence. |
| Redelivery (`E2E-09`) | [31193718861](https://github.com/Mayvins/timetabler-be/actions/runs/31193718861) | [31194322436](https://github.com/Mayvins/resource-booking-be/actions/runs/31194322436) | Immutable duplicate/delayed delivery produced no new source transaction or receiver application. |
| Synchronized conflict (`E2E-10`) | [31199593913](https://github.com/Mayvins/timetabler-be/actions/runs/31199593913) | [31199568642](https://github.com/Mayvins/resource-booking-be/actions/runs/31199568642) | Both contenders submitted in the same millisecond. Timetabler won and committed sequence 114; Resource Booking rejected HTTP 400 with `resource_sync_mode_mirror_only` and committed no contender. No conflict or partial state was accepted. |
| Restart (`E2E-11`) | [31201102800](https://github.com/Mayvins/timetabler-be/actions/runs/31201102800) | [31201897098](https://github.com/Mayvins/resource-booking-be/actions/runs/31201897098) | Exact publisher/consumer processes restarted with checkpoints retained and watermark unchanged at 114. |
| Rollback (`E2E-12`) | [31202036674](https://github.com/Mayvins/timetabler-be/actions/runs/31202036674) | [31202178039](https://github.com/Mayvins/resource-booking-be/actions/runs/31202178039) | Exact workers were restored, durable state was retained, and reverse delivery remained false. |
| Cleanup (`E2E-13`) | [31202768905](https://github.com/Mayvins/timetabler-be/actions/runs/31202768905) | [31203486498](https://github.com/Mayvins/resource-booking-be/actions/runs/31203486498) | Three source transactions, sequences 115–117, deleted nine activities, seven Staff, and seven Locations. Resource Booking recorded exactly one durable applied receipt for each transaction. |
| Final unfiltered reconciliation (`E2E-13`) | [31204013529](https://github.com/Mayvins/timetabler-be/actions/runs/31204013529) | [31204392182](https://github.com/Mayvins/resource-booking-be/actions/runs/31204392182) | Both services finished at watermark 117 with fixtures absent. Resource Booking's complete-snapshot dry run scanned 1,810 resources and 62 activities with drift, unresolved, quarantine, and repair all zero. |

Final immutable evidence SHA-256 values:

- Timetabler: `fe3dd7d64002cb04a9ce51d3c587f1155598c6ef6a8ca3e41e6894488bebe087`.
- Resource Booking: `5253eb6ef1e5270cee0bffd59f48166fef3a900cc8bf36c1d1c9124c14d7389a`.

Resource Booking committed its matching acceptance record as `848627a2440ce9c3431d12567a5ffcff069c449e` on `origin/dev`; deployment [31204948366](https://github.com/Mayvins/resource-booking-be/actions/runs/31204948366) passed and Resource Booking task 10.4 is checked complete.

This coordinated evidence closes Timetabler tasks 10.1–10.13 only. LOAD was not run, DR remains explicitly excluded, and no Phase 2 or reverse-delivery path was enabled.

## Verified cross-service evidence received

The following Resource Booking foundation evidence was verified on 2026-08-06 and remains accepted as partial input to this gate:

| Evidence | Verified result |
| --- | --- |
| Resource Booking Phase 1 release | `resource-booking-be` `origin/dev` at `fc9ecf670d8a1a542cba8b3efe7d1b057779285d` |
| Standard deployment | GitHub Actions run [31078563334](https://github.com/Mayvins/resource-booking-be/actions/runs/31078563334), `Deploy Resource Booking BE`, completed successfully for the exact release SHA |
| Resource Booking local QA | 1,258 tests passed with 48 PostgreSQL-only skips; Ruff, compile, migration drift, Django checks, and strict OpenSpec validation passed |
| Resource Booking PostgreSQL evidence | The isolated Phase 1 PostgreSQL suite is recorded as passing in `docs/TimetablerSyncPhase1Acceptance.md` at the release commit |
| Recovery hygiene | 14 temporary recovery artifacts and reset secrets/tooling were reported removed before release |
| Matching Resource Booking Phase 2 plan | Branch `codex/resource-booking-timetabler-phase-2` at `88c3cd5eaff085c70ab84f4e446b68268c87008b`; 26 requirements, 72 scenarios, 109 tasks, with strict validation reported passing |
| Resource Booking v2 receiver | `origin/dev` `a3dcecd0c50daff88bcd030dd5dc039b09d98feb`; staging run [31099640196](https://github.com/Mayvins/resource-booking-be/actions/runs/31099640196) passed with ingestion/repair/reverse false; shared scope `default`, topic `timetabler.activity.events`, and snapshot token configuration reported present |

This foundation evidence plus the live cutover above advances the Resource Booking implementation/deployment portion of Phase 1, but it does not complete tasks 9.5–9.7 or Phase 2 tasks 0.1–0.3.

Required evidence:

- Timetabler, adapter, and Resource Booking commit/build identifiers and deployed environments;
- approved event/transport/auth/calendar/timezone contract version;
- fully passing unit, integration, regression, failure-injection, concurrency, security, reconciliation, and performance suites in both services;
- single/bulk/reschedule/no-slot/variant/week/duration/unschedule/delete/swap/import/direct-writer/pre-schedule/final-drop/manual-constraint acceptance evidence;
- crash results before commit, after commit/before offset, and after offset;
- post-commit Redis/WebSocket/Kafka and adapter outage/replay evidence;
- worst-case transaction, resource-map, Redis refresh, approximately 30-second engine reservation, and Kafka max-poll measurements, with TTL extension/renewal evidence if the approved percentile misses budget;
- zero or explicitly approved reconciliation divergence, mirror-only conflict rejection, dashboard/alert exercise, rollback/resume exercise, and known limitations;
- explicit approvals with names, roles, timestamps, and links to immutable test artifacts.

Approval state: **BLOCKED — live continuous staging synchronization and scoped `E2E-01`–`E2E-13` are proven, but `LOAD-01`–`LOAD-08` is NOT STARTED, outstanding contract/ownership/calendar and other OpenSpec gates remain incomplete, and named Timetabler, Resource Booking, QA, product, and operations approvals are absent.**

The remaining load execution scope is defined in `phase1-e2e-load-test-plan.md`. Tasks 10.14–10.21 remain unchecked. Default thresholds and zero-tolerance correctness invariants remain binding; reverse delivery remains false. Any load execution may use only supported APIs, unique run IDs, and an approved non-production environment, and must finish with unfiltered reconciliation.

Disaster recovery is removed from this gate. Database backup/PITR restore, Kafka cluster rebuild/restore, host/AZ/region/site failover, infrastructure/DNS/secrets-vault rebuild, and multi-region/business-continuity exercises are explicitly excluded. Controlled process restart, safe application/release/configuration rollback, checkpoint recovery, durable resume, and reconciliation remain required and are not DR.

## Historical staging acceptance failure and recovery (2026-08-06 to 2026-08-07)

Resource Booking staging was reset and its live Staff and Location catalogues showed `No data available`. The deployed Resource Booking build had `RB_TIMETABLER_SYNC_INGESTION_ENABLED` absent/false, so no bootstrap or broker ingestion had populated Timetabler mirrors. This was an explicit Phase 1 acceptance **NO-GO**, not an approved empty baseline.

The original read-only deployment evidence showed:

- Timetabler build `b29ee4c21a04f7f4cb7cc7b36faa2484cf294007` deployed successfully in GitHub Actions run [31023018291](https://github.com/Mayvins/timetabler-be/actions/runs/31023018291), but its safe defaults are capture on, publication off, transport disabled, and no Kafka topic.
- The baseline Timetabler workflow delegated entirely to `~/deploy-staging.sh`, and the baseline code had no compatible authenticated HTTP snapshot or whole-change-set v2 transport contract.

The Timetabler v2 release corrected those provider-side gaps: one canonical composite per change set, globally ordered source sequence, deterministic occurrences, authenticated fixed-watermark snapshot, and protected-environment PM2 enforcement with default-off/fail-closed publication. Guarded bootstrap [31107516468](https://github.com/Mayvins/timetabler-be/actions/runs/31107516468) emitted 1,722 Staff and 72 Locations in 19 change sets from watermark 23 to 42. Resource Booking reconciliation [31107759339](https://github.com/Mayvins/resource-booking-be/actions/runs/31107759339) applied 1,794 resources and 46 activities with zero drift or quarantine; frontend deployment [31108668644](https://github.com/Mayvins/resource-booking-fe/actions/runs/31108668644) exposed the expected catalogues. The continuous cutover evidence above supersedes the former default-off runtime state.

The disable-until-reconciled instruction in `phase1-staging-bootstrap-no-go.md` was satisfied before the controlled activation above. That document remains the immutable historical incident/recovery procedure; reverse delivery remains disabled.

No checkbox or successful canary substitutes for the remaining executable evidence and named approvals. Phase 2 planning may be reviewed, but production-code work must not begin while this gate is blocked.
