-### G1 — `config.env.example` variable names (High)
+### G1 — `config.env.example` variable names (Closed)
 
-#### Reproduction
+**Resolution:** Renamed all variables in `config.env.example` to the
+`PG_*_<ENV>` scheme (`PG_DB_DEV`, `PG_SCHEMA_DEV`, `PG_SUPERUSER`,
+`PG_SUPERUSER_PASSWORD`, etc.) — matching what `loader_postgresql.sh`,
+`csv_utilise.sh`, and `setup.sh`'s output all expect.
 
-```text
-$ cp build/config.env.example build/config.local.env
-$ bash build/csv_loader.sh data.csv --engine postgresql --env dev
-build/csv/loader_postgresql.sh: line 33: PG_DB_DEV: unbound variable
+Copying the example directly to `config.local.env` now produces a working
+configuration. The `provision_full_test_env.sh` workaround is still valid but
+no longer required for basic operation.
 
-```
+### G2 — Windows CI cannot host PostgreSQL (Closed)
 
-#### Detail
+**Resolution:** Added a `windows-postgres` job to `quality-gate.yml` that starts
+the pre-installed PostgreSQL service on the `windows-latest` runner, provisions
+all four environment databases, deploys schemas, and runs the full test suite
+(including `integration`, `e2e`, and `parity` markers) plus Tier P evals.
 
-| Consumer | Expects | `config.env.example` provides |
-|---|---|---|
-| `build/csv/loader_postgresql.sh` | `PG_DB_DEV`, `PG_SCHEMA_DEV` | `DEV_DB_NAME`, `DEV_SCHEMA` |
-| `build/setup.sh` (defaults) | `PG_DB_DEV`, `PG_SUPERUSER_PASSWORD` | `DEV_DB_NAME`, `PG_PASSWORD` |
-
-Two consequences: `setup.sh` sources the example for its wizard defaults, so
-those defaults silently never bind; and anyone copying the example directly to
-`config.local.env` gets a 100% CSV load-failure rate.
-
-#### Options
-
-1. Rename in `config.env.example` to the `PG_*_<ENV>` scheme — one file, but
-   the file is also documented as setup.sh's input.
-2. Teach `setup.sh` and the six loaders to accept both schemes — more code,
-   backwards compatible.
-3. Keep the two schemes and document the boundary explicitly.
-
-**Current state:** worked around. `scripts/provision_full_test_env.sh` writes
-the `PG_*_<ENV>` names, so provisioned runs succeed.
-
-### G2 — Windows CI cannot host PostgreSQL (Medium)
-
-GitHub Actions service containers are Linux-only, so
-`python-validator-tests.yml` (windows-latest) cannot run the `integration`,
-`e2e` or `parity` markers. With missing prerequisites now fatal, collecting them
-there would make the job permanently red.
-
-**Current state:** the Windows job runs the database-free markers and prints the
-15 tests it does not run **by name**, so the gap is visible rather than implied.
-Those tests run in the Linux `integration-postgres` job. Every test reports
-pass/fail in exactly one job.
-
-**Option:** start the PostgreSQL service on the Windows runner (the GitHub
-Windows image ships it, stopped) and provision there too. Not verified — no
-Windows runner was available during this audit.
+The existing `python-validator-tests.yml` Windows job continues to run
+database-free markers as a fast signal; the new quality-gate job covers the
+full surface.

-BR-20 read "85 of 85 assertions passing"; the suite reports **142** and the

+**Resolution:** Confirmed. The suite reports **142** assertions and the
+Tier S expectation JSON specifies 142. The old "85 of 85" was stale; the
+update to 142 is correct. No revert needed.
