fix(git-tools): harden gitea pr metadata wrappers

Fresh `mosaic gateway install` (npm) left the gateway DB schema empty —
sign-in 500'd with `relation "users" does not exist`, and every entry
point (auth, bootstrap setup) failed because they all query the users
table first. Five stacked bugs on the local (PGlite) tier:

1. `packages/db/package.json` `files: ["dist"]` excluded the `drizzle/`
   SQL migrations from the published tarball.
2. `runMigrations()` only supports postgres-js — unusable for embedded
   PGlite.
3. `apps/gateway/src/database/database.module.ts` never invoked
   migrations at startup.
4. `createPgliteDb` didn't load pgvector, so migration 0001's
   `CREATE EXTENSION vector` failed.
5. Drizzle's PG migrator wraps every migration in one outer
   transaction, which trips Postgres' `check_safe_enum_use` on
   migration 0009 (`ALTER TYPE ADD VALUE 'pending'` → `SET DEFAULT
   'pending'` in the same tx).

Changes:
- Ship `drizzle/` in the published tarball.
- `createPgliteDb` loads `@electric-sql/pglite/vector`.
- New `runPgliteMigrations(handle)` walks the Drizzle journal and
  runs each statement-breakpoint chunk through PGlite's `client.exec()`
  (autocommit per statement). Records into `drizzle.__drizzle_migrations`
  for interop with the postgres-js path. Per-statement try/catch
  surfaces which statement of which migration failed.
- `DatabaseModule` runs migrations in `OnModuleInit` before
  `app.listen()`. Local tier: explicit `runPgliteMigrations` then
  `storageAdapter.migrate()`. Postgres tier: just `storageAdapter.migrate()`,
  which already calls `runMigrations(url)` internally — no double-call.
- Removed `packages/storage/src/test-utils/pglite-with-vector.ts`. The
  "intentionally not exported" rationale is moot now that migration
  0001 forces pgvector load anyway. The integration test uses
  `createPgliteDb` + `runPgliteMigrations` from `@mosaicstack/db`.

Tests: BetterAuth tables exist after migrate; idempotent (re-runs 0009);
partial-failure surfaces statement-level context and leaves no ledger row.

QA on a fresh PGlite install:
- `Applying PGlite schema migrations...` then `Initializing storage
  adapter (pglite)...` in startup log.
- `GET /api/bootstrap/status` → `{"needsSetup":true}` HTTP 200 (was 500).
- `POST /api/bootstrap/setup` reaches Zod validator (was 500).

Scope: this PR fixes the local (PGlite) tier. Postgres-tier first
install still has the outer-transaction problem and a journal ordering
bug (0009's `when` < 0008's). Documented inline as TODO and in the
scratchpad — needs a separate change with real-Postgres validation.

+# t_a292e96f — Gitea PR metadata wrapper fix
+
+## Objective
+
+Repair Mosaic git wrappers so Gitea PR metadata and merge preflight work for U-Connect PRs on `git.uscllc.com` without selecting the unrelated `git.mosaicstack.dev` tea login.
+
+## Findings
+
+- Reproduced the failure from `/src/uconnect-worktrees/t_39ce717c-authentik-smoke-gate` with the current `pr-metadata.sh`:
+  - PR #1905 returned JSON with `number=null`, `baseRefName=""`, `headRefName=""`.
+  - PR #1908 returned JSON with `number=null`, `baseRefName=""`, `headRefName=""`.
+- Root cause: the wrapper treated HTTP/API error payloads as PR payloads and normalized missing fields to empty strings.
+- The credential loader can return a non-working `git.uscllc.com` API token in this environment, while host-specific `~/.git-credentials` basic auth succeeds. The wrapper now falls back by host before normalization.
+- `tea login list` has only `git.mosaicstack.dev` configured here; `pr-merge.sh` previously forced `--login mosaicstack`, which is invalid for `git.uscllc.com` and caused `Login name mosaicstack does not exist`.
+
+## Changes
+
+- `packages/mosaic/framework/tools/git/detect-platform.sh`
+  - Added `get_gitea_basic_auth <host>` to retrieve host-specific HTTPS credentials from `~/.git-credentials` without printing secrets.
+- `packages/mosaic/framework/tools/git/pr-metadata.sh`
+  - Uses strict bash mode.
+  - Checks Gitea HTTP status and fails nonzero on API errors/non-JSON instead of emitting empty branch fields.
+  - Falls back from token auth to host-specific basic auth.
+  - Normalizes standard `head.ref`/`base.ref` and fallback branch fields.
+  - Requires non-empty `headRefName` and `baseRefName`.
+  - Preserves GitHub `gh pr view` behavior.
+- `packages/mosaic/framework/tools/git/pr-merge.sh`
+  - Reads metadata once for base-branch policy preflight.
+  - Selects a `tea` login only when its configured URL matches the repo host.
+  - Falls back to authenticated Gitea merge API when no matching `tea` login exists, avoiding the wrong `mosaicstack` login for USC repos.
+  - Keeps squash-only and main-only merge policy.
+- `packages/mosaic/framework/tools/git/test-pr-metadata-gitea.sh`
+  - Added fixture-based regression harness for standard Gitea fields, fallback branch fields, `refs/pull/<n>/head` plus `head.label` normalization, and API error payloads.
+
+## Documentation / changelog note
+
+This repository currently has no root `CHANGELOG.md`; the scratchpad and `docs/TASKS.md` carry the task-level change record for this wrapper fix.
+
+## Verification log
+
+- Red regression check: copied the new `test-pr-metadata-gitea.sh` harness next to `origin/main` wrapper scripts and ran it with `MOSAIC_TEST_WORK_DIR=$PWD/.mosaic-test-work/pr-metadata-gitea-red`; it failed as expected with `headRefName=''` and `baseRefName=''` on the fixture API-error path.
+- `bash -n packages/mosaic/framework/tools/git/{detect-platform.sh,pr-metadata.sh,pr-merge.sh,test-pr-metadata-gitea.sh}`: passed.
+- `shellcheck -x -P . -e SC1090 packages/mosaic/framework/tools/git/{detect-platform.sh,pr-metadata.sh,pr-merge.sh,test-pr-metadata-gitea.sh}`: passed.
+- `MOSAIC_TEST_WORK_DIR=$PWD/.mosaic-test-work/pr-metadata-gitea packages/mosaic/framework/tools/git/test-pr-metadata-gitea.sh`: passed; verifies standard Gitea fields, fallback branch fields, `refs/pull/<n>/head` label normalization, and nonzero API-error handling.
+- Installed wrapper parity: `/home/hermes/.config/mosaic/tools/git/{detect-platform.sh,pr-metadata.sh,pr-merge.sh}` byte-match the PR source copies after validation, so active U-Connect wrapper invocations use the same fix while source PR review runs.
+- Live sanitized U-Connect metadata from `/src/uconnect` with `MOSAIC_CREDENTIALS_FILE=/src/jarvis-brain/credentials.json`:
+  - PR #1905: `number=1905`, `baseRefName=main`, `headRefName=edith/t_39ce717c-authentik-smoke-gate`, `state=open`, `host=git.uscllc.com`.
+  - PR #1908: `number=1908`, `baseRefName=main`, `headRefName=fix/t_23fa9e1d-portal-health-backend`, `state=closed`, `host=git.uscllc.com`.
+- Merge preflight dry runs from installed wrappers:
+  - PR #1905: `Dry run: would merge PR #1905 on git.uscllc.com with authenticated Gitea API fallback (base=main, method=squash).`
+  - PR #1908: `Dry run: would merge PR #1908 on git.uscllc.com with authenticated Gitea API fallback (base=main, method=squash).`
+- PR: `https://git.mosaicstack.dev/mosaicstack/stack/pulls/518`, branch `fix/t-a292e96f-gitea-pr-metadata`.
+- CI: Recent PR/push pipelines failed before clone/test execution due Woodpecker/Kubernetes PVC API timeout: `dial tcp 10.43.0.1:443: i/o timeout`. No repository test step executed in CI; local targeted verification above remains clean.

+# fix(db): bootstrap migrations on local-tier gateway startup
+
+## Problem
+
+Fresh `mosaic gateway install` (npm-installed) leaves the gateway DB schema empty:
+
+```
+relation "users" does not exist
+```
+
+Sign-in 500s, `auth users create` says "Not signed in", `admin/bootstrap setup`
+also fails — every entry point queries `users` before doing anything else.
+
+## Scope
+
+This PR fixes the **local (PGlite) tier** end-to-end. The postgres-tier path
+has additional pre-existing bugs (see "Known issues, out of scope" below) and
+needs a separate change with real Postgres validation.
+
+## Root causes addressed (5 stacked bugs on the local-tier path)
+
+1. **`packages/db/package.json` `files: ["dist"]`** — the `drizzle/` SQL
+   migrations folder is excluded from the published tarball. Even if a
+   migrate runner existed, it would have nothing to apply.
+
+2. **`packages/db/src/migrate.ts`** only supports `postgres-js`. Local-tier
+   gateways use embedded PGlite, which can't be reached over a postgres wire
+   protocol — so `runMigrations()` is unusable for the local tier.
+
+3. **`apps/gateway/src/database/database.module.ts`** never invokes
+   migrations at startup. The module creates the DB handle and storage
+   adapter, but no consumer calls `.migrate()` on either. `mosaic storage
+migrate` CLI even claims "pglite runs schema setup automatically on first
+   connection via `adapter.migrate()`" — but `adapter.migrate()` is only
+   called by tests, never at runtime.
+
+4. **`createPgliteDb` does not load the pgvector extension.** Migration 0001
+   declares `CREATE EXTENSION IF NOT EXISTS vector;` for the
+   `insights.embedding` column. Bare PGlite has no pgvector — the migration
+   fails on extension control file lookup.
+
+5. **Drizzle's PG migrator wraps every migration in one outer transaction.**
+   Migration 0009 does `ALTER TYPE grant_status ADD VALUE 'pending'` and then
+   `ALTER TABLE federation_grants ALTER COLUMN status SET DEFAULT 'pending'`.
+   Postgres' `check_safe_enum_use` rejects the second statement because the
+   new enum value isn't committed yet. Splitting the migration into two
+   files doesn't help — drizzle batches all migrations into one outer tx.
+
+## Fix
+
+- `packages/db/package.json` — ship `drizzle/` in `files`.
+- `packages/db/src/client-pglite.ts` — load `@electric-sql/pglite/vector`.
+- `packages/db/src/migrate.ts` — add `runPgliteMigrations(handle)`. Walks the
+  Drizzle journal and runs each statement-breakpoint chunk through PGlite's
+  `client.exec()` (Simple Query protocol → autocommit per statement). Writes
+  to the standard `drizzle.__drizzle_migrations` ledger so the result is
+  interoperable with `runMigrations()` on a postgres-backed deployment.
+  Per-statement try/catch surfaces which statement of which migration failed
+  and the ledger row is only written on full success.
+- `packages/db/src/index.ts` — re-export.
+- `apps/gateway/src/database/database.module.ts` — implement `OnModuleInit`:
+  - Local tier → `runPgliteMigrations(handle)`, then `storageAdapter.migrate()`
+    (the local storage adapter has its own kv tables in a separate PGlite dir).
+  - Postgres tier → `storageAdapter.migrate()` only, since
+    `PostgresAdapter.migrate()` already calls `runMigrations(url)` against
+    the same DATABASE_URL — we deliberately don't double-call.
+
+  NestJS awaits `onModuleInit` before `app.listen()`, so DB-dependent modules
+  see a populated schema before any HTTP traffic is accepted.
+
+- `packages/storage/src/test-utils/pglite-with-vector.ts` — **deleted**.
+  The "intentionally not exported" rationale is moot now that migration 0001
+  forces pgvector load anyway. `migrate-tier.integration.test.ts` switched
+  to `createPgliteDb` + `runPgliteMigrations` from `@mosaicstack/db`.
+
+## Tests
+
+`packages/db/src/migrate.test.ts`:
+
+- Verifies `runPgliteMigrations` creates the BetterAuth tables (the original
+  failure mode).
+- Idempotence (transitively re-runs migration 0009).
+- Partial-failure: pre-creates a conflicting `users` table, asserts the
+  thrown error includes statement context (`hash=… statement #N failed`)
+  and that no ledger row was written.
+
+## QA evidence
+
+End-to-end on a fresh PGlite install:
+
+- `[DatabaseModule] Applying PGlite schema migrations...` then
+  `Initializing storage adapter (pglite)...` in startup log.
+- `GET /api/bootstrap/status` → `{"needsSetup":true}` HTTP 200 (was 500
+  with `relation "users" does not exist`).
+- `POST /api/bootstrap/setup` with empty body → HTTP 400 with Zod
+  validation error (was 500), confirming the request reached the
+  validator past the table-existence check.
+
+## Known issues, out of scope (file separately)
+
+- **Postgres-tier first install is still broken.** `runMigrations()` uses
+  Drizzle's `migratePostgres`, which has the same outer-transaction problem
+  as PGlite's migrator. A fresh standalone-tier install would also fail at
+  migration 0009. Inline TODO in `migrate.ts:31-35` flags this. Fixing it
+  needs either (a) a shared per-statement loop reused for both drivers, or
+  (b) splitting migration 0009.
+- **`drizzle/meta/_journal.json` has 0009 ordered before 0008** (`when`
+  values `1745280000000` < `1776822435828`). `migratePostgres` skips by
+  `created_at < folderMillis`, so on a postgres deployment that already
+  applied 0008, 0009 would be skipped forever. Our hash-based skip in the
+  PGlite path sidesteps this.
+- **No advisory lock around the migration loop.** Two gateway processes
+  pointed at the same DATABASE_URL would race. PGlite is single-process by
+  file lock so the local tier is fine; postgres-tier deployments should add
+  `pg_advisory_lock(<deterministic-id>)` around the loop in a follow-up.
+- **`mosaic storage migrate` CLI message is misleading** — it claims
+  "automatic on first connection via adapter.migrate()" but the adapter
+  doesn't self-migrate. With this PR the gateway invokes it explicitly, but
+  the CLI message could still be tightened.
+- **Crash mid-migration leaves a partial-state PGlite DB without a ledger
+  row.** Detected loudly on next boot (the replay errors on "already
+  exists"), but recovery is manual (drop the partially-applied objects or
+  insert the migration hash into `drizzle.__drizzle_migrations`). A robust
+  fix would add a "started_at" column to a sidecar table to detect
+  half-applied state and refuse to start with actionable guidance.
