# M5 coordinated release train — deployment readiness and execution control

- Status: **Released**
- Train confirmation: `2026-07-17 KST` — lead reconciliation of the M5 common release evidence and individual release evidence
- Date: 2026-07-16
- Coordinator: TREX lead
- Scope: `trex-core` REL-011, `portfolio-hub` REL-004, `trex-web` REL-002
- Authority: This document coordinates release order and shared stop criteria. It **does not replace** each service's release document, runbook, release approval, or operator-owned deployment procedure.

## 1. Decision statement

The M5 coordinated train is **Released**. The lead reconciled the M5 common evidence handoff with the individual, release-specific records: `trex-core REL-011` is released; `portfolio-hub REL-004` is released with a documented non-blocking test-fixture follow-up; and `trex-web REL-002` is released. The later `trex-core REL-012` is a separately released post-M5 hotfix and is not a prerequisite for this M5 decision.

No release is inferred merely from source publication: this closure relies on the recorded service-specific operational evidence and decisions cited in the inventory below. Deferred follow-ups remain owned by their respective services and do not reopen the completed M5 train.

## 2. Release inventory and evidence

| Order | Service / release | Pinned application source | Evidence supporting an execution request | Non-negotiable outstanding gate |
| --- | --- | --- | --- | --- |
| 1 | `trex-core` REL-011 / BAT-057 | `6d90f8951dbf354eb41301492d0bcaf0af24d882` (runtime PR #42 merge `94e148940adb008db0bbd215052a1e984f7c566b`) | **Released** — Justin Ko approval `32675`, rollback SHA `7845fbe`, controlled daemon restart, startup health, and read-only smoke captured in [REL-011 execution evidence](../releases/evidence/rel-011_20260717_execution-evidence.md) | No remaining core release gate; this does not authorize live sync |
| 2 | `portfolio-hub` REL-004 / BAT-024, BAT-025 | `914b3dc6e6b9e2cbd7068fb30435c83f0581eab5` or reviewed descendant | **Released with deferred non-blocking test-fixture follow-up** — backup PASS; migration `20260715_0028`, schema invariants, `73 → 73` row-count preservation, Supervisor restart, `/health` 200, `db_enabled: true`, owner read PASS, non-owner HTTP 403 | No train-blocking gate; `owner_user_id` fixture follow-up remains service-owned |
| 3 | `trex-web` REL-002 / BAT-010 | `1ec2cf4345310cab0d3468e36b31e0613668b482` or approved descendant | **Released** — build/runtime install PASS; Supervisor RUNNING on `8004`; external `/trex/` and sign-in HTTP 200; authenticated portfolio UI/session checks PASS; browser-console JS errors 0 | No train-blocking gate; npm audit low/moderate notice remains service-owned |

## 3. Shared prerequisites before any execution

1. Record an explicit release-window approval for the specific REL; an approved document push is not deployment approval.
2. Record operator, window, target host/environment, source/artifact pin, and the currently working rollback source/artifact **before** changing a process or database.
3. Confirm the release's source is exactly pinned or a separately reviewed descendant. Never deploy an unpinned branch head.
4. Keep credentials, `.env` values, tokens, backup contents, bearer headers, and customer/portfolio data out of chat, terminal capture, and release documents.
5. Run only the service-owned runbook commands or the real operator-owned platform procedure. Local test Compose files, guessed systemd commands, and ad-hoc production command substitutions are prohibited.
6. Capture secret-free command exit status, timestamps, PID/rollout state, health/status result, and rollback decision in the corresponding REL evidence table.

## 4. Coordinated execution order

### Step 1 — trex-core REL-011 (independent, urgent broker-truth hotfix)

Execute only after REL-011 approval. Capture the current deployed SHA, update to the pin, use the existing supervisor to restart the core daemon, then perform only the runbook's read-only checks (`sync --all --dry-run` and `verify`) against the approved instance. `sync --live --yes`, slot/order mutation, automatic remediation, and changing `credential_fetch_enabled` are outside this release.

**Proceed to Step 2 only when:** the daemon remains healthy, logs show no startup/fatal error, the read-only checks have their expected no-write classification, and no rollback trigger occurs.

### Step 2 — portfolio-hub REL-004 (highest-risk: production DB migration)

Execute only after independent REL-004 approval and the backup/DB gates pass. Perform the approved backup and capture Alembic `heads/current`, active workload/locks, schema state, and row counts. Upgrade exactly to `20260715_0028`, prove the four metadata columns/default/not-null/row-count invariants, then use the existing operator-owned rolling deployment procedure. Start with read-only health and existing-read checks; a manual-ledger mutation smoke needs separate explicit approval for a designated non-sensitive test portfolio.

**Proceed to Step 3 only when:** migration postchecks pass, portfolio-hub health reports `db_enabled: true`, existing read paths work, authorization checks are correct, and the agreed observation period is clean.

### Step 3 — trex-web REL-002 (presentation release after dependencies are healthy)

Before stopping the process, reconcile the actual reverse-proxy upstream with the active deploy script and explicitly record the chosen app port. Stop if `/trex` is stripped or if the proxy target differs from the selected port. After portfolio-hub is healthy, build and start through `scripts/deploy-trex-web.sh`, then smoke the reverse-proxy route—not only localhost—for sign-in, portfolio list, safe existing portfolio detail, selected state/table readability, refresh/session, and logs.

## 5. Stop and rollback boundaries

| Release | Stop immediately when | Permitted recovery |
| --- | --- | --- |
| core REL-011 | missing approval/pin, daemon startup failure, error/no-write barrier failure, unexpected broker mutation risk | use captured pre-release source with the normal supervisor restart; retain all evidence; no live sync as a diagnostic shortcut |
| portfolio REL-004 | missing backup, unknown/branched Alembic state, lock/workload not accepted, migration/schema/null/row-count mismatch, health or authorization anomaly | before success: do not deploy new code; after migration success: roll back only to compatible code and retain additive schema `20260715_0028`; no downgrade, column drop, or restore without separate incident approval |
| web REL-002 | unresolved 3000/8004 proxy decision, `/trex` stripped, build/start failure, sign-in/portfolio regression, material readability regression | stop new process, restore captured known-good revision with the approved script, and recheck `/trex`, sign-in, portfolio list; no DB rollback applies |

## 6. Release completion rule

A service becomes `released` only after its own runbook evidence is complete and the lead records `confirm-release`. Do not mark the M5 train released because a source commit was pushed, a build passed, or another service succeeded.

The coordinated train closes only when all intended service releases have individual evidence and decisions, or when deferred/excluded services are explicitly recorded with rationale and follow-up ownership.

## 7. `confirm-release` — M5 train

**Released.** The intended M5 scope is closed with recorded individual release decisions:

1. `trex-core REL-011`: released; approval, pin, rollback revision, restart, and dry-run/verify evidence complete.
2. `portfolio-hub REL-004`: released; its `owner_user_id` test-fixture item is explicitly deferred and non-blocking.
3. `trex-web REL-002`: released; proxy port `8004`, external `/trex` route, sign-in, authenticated portfolio flow, and browser-console checks passed.

`trex-core REL-012` is recorded separately as a post-M5 hotfix. It does not change M5 scope or the train’s completion decision.
