+# Phase 12B — SQLite → PostgreSQL 16 big-bang migration report
+
+**Date:** 2026-04-21
+**Branch:** `phase-12b-postgres`
+**Cut-over window:** 2026-04-21 ~18:15 → ~18:47 UTC (≈ 32 min)
+**Rollback path:** SQLite dump snapshot + previous container image (unused — migration succeeded on first attempt)
+
+---
+
+## 1. Executive summary
+
+The Phase 12B migration moved the entire SatRank backing store from
+better-sqlite3 (single file on the api host, WAL mode) to PostgreSQL 16
+running on a dedicated Hetzner cpx42 VM in nbg1.
+
+- **Strategy:** big-bang (no dual-write, no ETL), chosen because prod
+  has 0 user baseline RPS and 12 291 agents indexed at T-0 (of which
+  8 182 had active bayesian streaming posteriors at the moment of the
+  cut-over decision) — a one-shot cut-over is simpler to reason about
+  than an active/active mirror.
+- **Downtime:** ≈ 32 min measured container-to-container. No user-facing
+  request was in flight during the window (0 RPS baseline).
+- **Data loss:** none expected from the schema side (v41 consolidated
+  DDL applied idempotently). One **data population gap** detected
+  post-cut-over on `service_endpoints.category` (Finding B) and one
+  **type-regression** on `score_snapshots.n_obs` BIGINT vs DOUBLE
+  PRECISION (Finding A, resolved in commit `d9128e6`) — both logged as
+  Phase 12C OPS issues, neither compromised agent indexation (Finding A
+  blocked new snapshots post cut-over until hotfix; pre-existing rows
+  intact).
+- **LND status:** intact throughout. No channel op, no macaroon churn,
+  no LND container restart.
+- **Tests:** 110 failed → 0 failed across the B3 sweep. 1 041 tests
+  passing pre-cut-over (B3.d), 1 044 passing post-B6 (warmup test
+  added). Zones critiques (bayesian, verdict, security, scoring,
+  decide, intent, probe, nostr) all at 0 failure.
+
+Prod is live on Postgres 16 as of this report. `satrank-postgres` VM
+retained as a production dependency.

+## 3. Architectural decisions
+
+### 3.1 Dedicated Postgres VM (cpx42) rather than co-locating on the api host
+
+Rationale:
+- The api host (cpx32, running bitcoind + LND + api + crawler) is
+  already storage-IO bound when the crawler writes in bursts. Putting
+  Postgres on the same host would compound that.
+- Scaling Postgres vertically is cheap with Hetzner — `cpx42` doubles
+  RAM and vCPU for a small monthly delta vs the api host, and it isolates
+  blast radius: a pg tuning regression does not crash the api / LND.
+- The cost of the dedicated VM is acceptable under the 0-user baseline.
+
+Trade-off: one network hop per query (intra-DC, single-digit ms). The
+iso-network smoke (B7) confirms server-side p95 sits at ~55 ms on
+/api/agents/top — well within the budget.
+
+### 3.2 Skip ETL / dual-write, big-bang cut-over
+
+Rationale:
+- Zero-user baseline → no need to preserve a stream of live writes.
+- Agent data is regenerable by the crawler (LN graph rebuilds in ~60 s
+  on first pass). Probe/attestation history is append-only and was
+  considered disposable for this migration window (see B0 strategy doc
+  — prod `probe_results` table was 2 108 231 rows, all replayable if
+  needed through the crawler).
+- Single failure mode: either the new pg container starts healthy with
+  v41 schema, or we rollback to the SQLite snapshot. No split-brain.
+
+The dual-write tests under `src/tests/dualWrite/` (from the Phase 1
+migration era) were retained `describe.skip`'d — they are not needed
+for this big-bang but document the alternative path for any future
+migration.
+
+### 3.3 Double-gate `L402_BYPASS` (kept from Phase 12A)
+
+Staging benches and Phase 12B probes needed `L402_BYPASS=true` to avoid
+the per-IP rate limiter. The double-gate — `L402_BYPASS=true` is
+refused at boot when `NODE_ENV=production` — prevents the flag from
+silently disabling rate limits on prod if someone copies a staging
+env file. This stayed in place and was extended in B6.2: `/metrics`
+scrapes are open only under `L402_BYPASS=true`; on prod they require
+`X-API-Key`.
+
+### 3.4 Schema consolidation v29+phase7–9 → v41
+
+Rather than run 12+ migration files sequentially against an empty
+Postgres, the B3 DDL ships as a single idempotent `postgres-schema.sql`
+that yields v41 in one shot. New columns (`operator_*`, `streaming_posteriors`,
+`report_bonus_log`, `preimage_pool`) are inlined in the base DDL. The
+`schema_version` table is seeded to 41 at the end of the one-shot apply.
+
+## 4. Issues encountered and resolutions
+
+### 4.1 `env_file` surprise during cut-over
+
+The `docker-compose.yml` on prod referenced `.env` but also had a
+second layer of env_file defaults baked into the Dockerfile. When
+switching to Postgres, the new `DATABASE_URL` had to be exported in
+**both** locations before the container would pick it up (env_file
+loads before Dockerfile ENV). Resolved in B5 by refreshing both before
+`docker compose up --force-recreate`.
+
+### 4.2 SQLite Docker volume path
+
+The B5 checklist initially guessed `/var/lib/satrank/satrank.db` for
+the pre-cut-over snapshot (borrowed from staging). Prod actually had
+the DB under `satrank_satrank-data` Docker volume at
+`/var/lib/docker/volumes/satrank_satrank-data/_data/satrank.db`. The
+checklist was updated to resolve the mountpoint dynamically via
+`docker volume inspect … --format '{{.Mountpoint}}'` before running
+the `sqlite3 .backup` snapshot.
+
+### 4.3 Test debt — 110 failures → 0 via targeted sweeps
+
+Starting point (post B3.b): **110 failed / 907 passed / 329 skipped**.
+The failures clustered into 4 patterns, swept in order:
+
+1. `db.prepare(...)` / `db.transaction(...)` residual legacy SQLite —
+   ported where cheap, `describe.skip`'d where the suite was
+   migration-era (dualWrite, phase3EndToEndAcceptance).
+2. Async propagation holes — controllers that `.then()`-ed on the old
+   sync repository methods needed `await`. Surfaced by runtime type
+   errors, not by the type checker alone.
+3. Connection lifecycle in tests — `closePools()` was added to every
+   suite's `afterAll` hook; a `Cannot use a pool after calling end` on
+   the warmup test is now the only such surface and it is the
+   intentional error path.
+4. Fixtures that assumed the SQLite row ID autoincrement starts at 1
+   — rewired to read back the `RETURNING id`.
+
+Final (B3.d): **0 failed / 1 041 passed / 312 skipped**. Remaining
+**268 TypeScript errors in tests** are documented in
+`docs/phase-12b/REMAINING-TEST-DEBT.md` — excluded from `tsc --noEmit`
+via `tsconfig.json`, not part of the prod build. Phase 12C scope.
+
+## 5. Iso-network smoke results (B7, 2026-04-21 18:21 UTC)
+
+Full writeup: `docs/phase-12b/ISO-NETWORK-SMOKE-2026-04-21.md`.
+
+| Endpoint | Metric | Paris A6 (WAN) | nbg1 B7 (iso-net) | Server-side share |
+|----------|--------|-----------------|--------------------|-------------------|
+| `/api/agents/top` p95 | ms | 332.7 | 54.8 | ~16 % |
+| `/api/agents/top` p99 | ms | 375.3 | 72.1 | ~19 % |
+| `/api/intent` p95    | ms | 289.4 | 53.8 | ~19 % |
+
+**Conclusion:** the Paris A6 ×107 staging-vs-prod warning is confirmed
+as WAN-dominated. Post-migration Postgres latency is ~55 ms p95 on
+`/api/agents/top` from an in-DC client, within the budget for the
+current load profile.
+
+## 6. Findings for Phase 12C
+
+Findings (`docs/phase-12c/OPS-ISSUES.md`):
+
+- **Finding A — `score_snapshots.n_obs` BIGINT rejects decayed floats**
+  — HIGH severity, **RESOLVED in Phase 12B hotfix** (commit `d9128e6`).
+  The SQLite INTEGER permissive typing was ported as BIGINT without
+  semantic review, while the column actually stores
+  `round3(nObsEffective)` (decayed real-valued weight). ALTER to DOUBLE
+  PRECISION completed on prod in 128.7 ms; 12 291 pre-existing rows
+  (all `n_obs = 0`) converted losslessly; 5 515 new snapshots written
+  post-fix in the first rescore cycle with zero bigint errors.
+- **Finding B — `/api/intent/categories` returns `[]` post-migration**
+  (detected during B7 smoke) — MEDIUM severity, **OPEN**.
+  `service_endpoints.category` filter yields no rows. Three-step
+  diagnostic laid out in OPS-ISSUES. Affects only `/api/intent` at
+  content level (latency OK).
+- **Finding C — `scoringStale: true` pre-existing before B5** — LOW
+  severity, **OPEN**. `/api/health` showed scoring age ~12 h on prod
+  during B5 prep. Not migration-related; 0 user impacted. May resolve
+  naturally once Finding A hotfix lets `computed_at` progress on
+  `score_snapshots` — to verify after one full post-hotfix cycle.
+
+Engineering debt:
+
+3. **268 TypeScript errors in `src/tests/**`** — excluded from build.
+   Documented in `docs/phase-12b/REMAINING-TEST-DEBT.md` with
+   per-file count and port/skip classification.
+4. **CI/CD for the Postgres path is not wired yet** — the test harness
+   runs locally against a dev Postgres container, but no GitHub Actions
+   job spins one up. Phase 12C: add `postgres:16` service container to
+   the CI workflow so test debt can't creep back in.
+5. **Nightly `pg_dump` backup is not scheduled** — the `npm run
+   backup:prod` script exists and points at pg, but no cron / systemd
+   timer invokes it on the prod VM. Phase 12C: wire a daily
+   `pg_dump --format=custom` to an off-host location (Hetzner Storage
+   Box or similar) with a 7-day retention.
+
+Carry-over security finding:
+
+6. **Nostr signing-key rotation** — raised in Phase 11/13A backlog and
+   not addressed in Phase 12B. The current npub / nsec pair has been
+   signing kind 30382/30383/30384/20900/5 events since Phase 8. Rotation
+   requires NIP-26 delegation or a kind 0 re-issue. Out of scope for
+   a DB migration phase; carry to Phase 13A.
+
+## 7. What worked and what I would do differently
+
+Worked well:
+- **Consolidated DDL.** Shipping v41 as one idempotent file eliminated
+  an entire class of mid-migration edge cases.
+- **Double-gate `L402_BYPASS`.** No accidental prod exposure of any
+  staging-only affordance (rate limiter skip, /metrics open scrape).
+- **Test-debt sweeps by pattern.** Bucketing the 110 failures into 4
+  root causes, each fixable with a repeatable mechanical edit, turned
+  what looked like a multi-day slog into a half-day cleanup.
+
+Would do differently:
+- **Backup path as part of the CI baseline.** The B5 guess on the
+  SQLite mountpoint was a near-miss. The backup command should be
+  exercised in staging (where the same Docker-volume pattern applies)
+  at least once before every prod cut-over.
+- **Active check for `service_endpoints` row health post-migration.**
+  The `/api/intent/categories` empty list was only caught by the B7
+  smoke. A minimal DB health probe (row counts on critical mapping
+  tables) should run as part of the post-cut-over checklist.
