ConnorYohandGitHub ff96a80947 PAYG B-3 / S-3: cucumber suite for shadow-mode flows + CI workflow (#6522)
## What this PR is

End-to-end cucumber coverage for the PAYG shadow charging engine (the
filter + interceptor stack from #6519), wired into CI via a new
`docker-compose-tests-saas.yml` workflow that runs only on PAYG-touching
PRs.

Stacked on #6519.

## Automated scenarios (run by `docker-compose-tests-saas.yml`)

See
[`testing/cucumber/features/payg/shadow_charges.feature`](../tree/payg-s3-cucumber/testing/cucumber/features/payg/shadow_charges.feature):

| Scenario | Validates |
|---|---|
| First tool call writes a CHARGED row | Filter + interceptor fire
end-to-end |
| Lineage join — second call on output | `JobService.joinOrOpen`
matching; no new shadow row |
| 4xx leaves the row CHARGED | "Customer paid for the attempt" semantics
|
| ZIP-returning tool records per-PDF OUTPUT | `PaygOutputExtractor`
unpacks + records signatures |
| Multi-file input writes a single shadow row | Multi-input group sizing
|
| `X-Stirling-Automation` sets PIPELINE source | Header → `JobSource`
detection |

All 6 run locally via `./testing/test-payg.sh` and will run on CI for
any PR that touches `app/saas/**`, the PAYG cucumber features, the saas
compose stack, or the workflow itself.

## Manual-only scenarios — documented in design doc, not in this suite

Two parts of the shadow engine are deliberately not automated; the
engine paths are unit-tested in
`PaygChargeInterceptorTest.afterCompletion_5xx_opened_*`, and the manual
procedures (which require a temporary throw endpoint or a container
restart with a flag flipped) live in [`notes/PAYG_DESIGN.md` §7.5.2
"PAYG cucumber: manual-only
scenarios"](../tree/payg-s3-cucumber/notes/PAYG_DESIGN.md).

- **5xx first-step failure → REFUNDED + CLOSED.** No reliably-5xx-ing
endpoint exists; manual procedure adds a throw endpoint, runs, asserts,
removes.
- **Kill-switch (`PAYG_FILTER_ENABLED=false`).** Needs a container
restart mid-suite; manual procedure tears down, flips env, brings up,
asserts zero shadow rows.

If either gets a hot-reload path (test-only throw endpoint shipped
behind a profile gate, or admin endpoint for the kill switch), automate
it in a follow-up and drop the manual procedure.

## CI workflow

`.github/workflows/docker-compose-tests-saas.yml` (new) —
self-contained, not wired into `build.yml`'s `files-changed` matrix so
the saas-cucumber job fails and succeeds independently. Triggers only on
PAYG-relevant paths. No JaCoCo coverage in v1 (saas compose doesn't have
the coverage override; can add later).

## Test infrastructure (recap)

- **`testing/compose/docker-compose-saas.yml`** — Stirling-PDF backend
with `STIRLING_FLAVOR=saas` + Postgres holding the `stirling_pdf`
schema. Supabase JWT auto-config disabled; API-key auth via
`SECURITY_CUSTOMGLOBALAPIKEY` is the live path the cucumber tests
exercise.
- **`testing/compose/payg/saas-init.sql`** + **`saas-seed.sql`** —
schema bootstrap + idempotent seed (team / user / wallet_policy).
- **`testing/cucumber/features/payg/shadow_charges.feature`** — the 6
scenarios above.
- **`testing/cucumber/features/steps/payg_step_definitions.py`** — step
defs using `requests` (HTTP) + `psycopg` (direct DB inspection). Direct
DB reads are deliberate — we want to see the filter's side effects, not
relay them through another API layer.
- **`testing/test-payg.sh`** — companion runner to `testing/test.sh`.
Brings up the saas compose, waits for health, seeds, runs behave, tears
down.
- **`behave.ini`** excludes `features/payg` from the default behave run
(the saas-cucumber CI job invokes it explicitly).

## Why a separate harness from `testing/test.sh`

The existing `test.sh` covers the proprietary-flavour stack (no PAYG
tables, no saas profile). Coupling two CI matrices that fail and succeed
independently into one script is asking for trouble. Keep the
saas-cucumber job focused on its own concerns; once the harness is
mature, the wider team can decide whether to merge them.

## Tracked in

`notes/PAYG_DESIGN.md` §7.5 (PR-S3) + §7.5.2 (manual scenarios).

-- Bootstrap minimal stirling_pdf state for PAYG cucumber tests.

-- Runs once when the postgres-saas container is first created (loaded via
-- /docker-entrypoint-initdb.d on the official postgres image). Flyway then
-- migrates V1-V13 on backend startup, which fills in the schema; this file
-- only seeds the data rows the cucumber scenarios reference by name.
--
-- Idempotent — if the container is re-created, this whole file runs again
-- but every INSERT is guarded against duplicates.
CREATE SCHEMA IF NOT EXISTS stirling_pdf;
-- Note: the actual seed of teams / users / payg_team_extensions / wallet_policy

-- helper function the backend invokes once at startup (or the cucumber
-- harness invokes via psql before running scenarios).
--
-- For "make a start", the simplest approach is to keep this file as the
-- schema bootstrap, and put the seed inserts in a separate sidecar SQL that
-- the cucumber test.sh harness pipes through psql AFTER waiting for backend
-- health. See testing/compose/payg/saas-seed.sql below.
-- Reserved for future container-init-time schema bootstrap if we ever need it.
