docs(p010): implementation report + production evidence for Data-OS completion

From-scratch verification (fresh clone, fresh installs) backing up the P010
completion pass: 256/256 vitest, 28/28 pytest, clean typecheck/build on the
committed tree, pre-existing-only lint noise. Documents that
OPT_QUALITY_BRIDGE_ENABLED ships off and stays off in this PR -- activating
it in production is left as Simon's decision, with a readiness checklist.

+# IMPLEMENTATION_REPORT.md — P010 Data-OS completion (sax3l/0pt)
+
+**Branch:** `feat/p010-data-os-completion` (renamed mid-pass from
+`feat/p010-source-registry-persistence` once scope grew beyond persistence
+alone).
+**Base:** `origin/main` @ `f8bb0d5` (verified in sync via `git fetch --prune`
+before starting; `origin` = `git.siax.io/sax3l/0pt`, the canonical remote per
+`CLAUDE.md` — the GitHub copy was not touched).
+**Commits on top of base:** `07b13bd` (Source Registry Postgres persistence +
+HTTP route surface), `9740e20` (TS/Python quality bridge + provenance fields
++ fault-injection tests).
+**Report date:** 2026-09-01. Written after a from-scratch verification pass
+(fresh clone, fresh `pnpm install`, fresh Python venv — not a rerun of the
+working tree that built the branch), so the numbers below are reproducible,
+not just remembered.
+
+This report follows `BEFORE_STATE.md`'s classification scale: `VERIFIED` /
+`IMPLEMENTED_NOT_VERIFIED` / `DOCUMENTED_ONLY` / `STALE` / `BROKEN` /
+`UNKNOWN`. Read `BEFORE_STATE.md` first — this report only describes the
+delta from it.
+
+---
+
+## 1. What actually changed, mapped to BEFORE_STATE.md's 5 gaps
+
+### §1 Source Registry persistence — `VERIFIED` closed
+
+- New `src/repositories/*` layer: `SourceRepository` /
+  `SourceRegistryRepository` interfaces, each with an `in-memory` and a
+  `postgres` implementation (`postgres-source-repository.ts`,
+  `postgres-source-registry-repository.ts`). `src/repositories/db.ts` is a
+  thin pooled-client wrapper honoring `resolveStoreMode`
+  (`src/platform/dependency-mode.ts`) — the same guard BEFORE_STATE.md noted
+  as already blocking production boot without a DB; it now has a Postgres
+  implementation to fall through to instead of only throwing.
+- `sql/002_source_registry.sql` — new migration: `opt_sources`,
+  `opt_source_rights`, `opt_source_provenance`, `opt_source_health_checks`,
+  every table keyed by `source_id` with a `tenant_id` column and index — this
+  is exactly the schema shape BEFORE_STATE.md §1 derived as "what Postgres
+  migration would require" but said did not exist. It now exists and is
+  applied.
+- `src/services/source-service.ts` and `source-registry-service.ts`
+  rewritten to take a repository (constructor-injected), closing the
+  **per-instance-Map** defect BEFORE_STATE.md flagged as worse than plain
+  in-memory: every route module now shares one repository-backed instance
+  (`src/services/source-registry.ts` is the new shared-singleton wiring),
+  not a fresh `Map` per `new SourceService()`.
+- New route surface closing BEFORE_STATE.md's "effectively zero HTTP routes"
+  finding: `app/api/0pt/sources/route.ts` (create/list — did not exist
+  before), `[sourceId]/route.ts` (get/describe — did not exist before),
+  `[sourceId]/rights`, `[sourceId]/provenance`, `[sourceId]/health`,
+  `[sourceId]/freshness` (all new). `[sourceId]/query` and
+  `rate-policies/*` (pre-existing routes) were touched only to repoint them
+  at the shared singleton instead of constructing their own service.
+- `tests/p0/source-registry-postgres.realinfra.test.ts` (340 lines, 7
+  tests) — a **real-Postgres** suite, not a mock. It self-skips honestly
+  (not fabricating pass) when no reachable Postgres is configured for the
+  run; see §2 (Testing) below for what this pass actually observed.
+
+**What is still NOT true, stated plainly:** in-memory mode is still the
+default when no `DATABASE_URL`/Postgres is configured — this pass added a
+real persistence *option*, it did not remove the in-memory path (removing it
+would break every existing unit test and any deployment without Postgres
+wired yet). `resolveStoreMode` still hard-blocks production boot without a
+real DB configured, which is correct behavior, not a residual bug.
+
+### §2 TS/Python split-brain — `VERIFIED` bridged (additive, advisory)
+
+- **New route surface**, `app/api/0pt/quality/*`: `rules` (list/create),
+  `rules/[ruleId]` (get/update), `runs` (list/create), `runs/[runId]` (get),
+  `issues` (list), and `POST /api/0pt/quality/bridge-run` — the entry point
+  the Python side calls. All sit over one shared `QualityService` singleton
+  (`src/services/quality.ts`), fixing the same "no shared instance across
+  route modules" class of defect the Source Registry had.
+- `src/quality/quality-bridge.ts` auto-provisions a deterministic,
+  tenant-scoped baseline rule set on first use, so the Python engine never
+  has to pre-register rules through the CRUD surface — it just calls
+  `bridge-run` and gets a score back against rules that already exist.
+- **Python side**, `services/api/workers/quality_bridge.py`: an HTTP client
+  to the route above.
+  - **Feature-flagged off by default**: `OPT_QUALITY_BRIDGE_ENABLED` unset
+    or falsy → zero network calls, returns immediately (`status:
+    "disabled"`). Verified in code (`_enabled()`, `services/api/workers/
+    quality_bridge.py:59-60`) and in tests
+    (`test_disabled_by_default_makes_zero_network_calls`).
+  - **Fails open, unconditionally.** Every failure mode — bridge URL unset,
+    connection refused, timeout, non-2xx, malformed JSON — is caught inside
+    the module and reported back as a `BridgeResult` with a `status` field
+    (`disabled` / `not_configured` / `unavailable` / `ok`), never raised into
+    `run_job`. `pipeline.py`'s actual delivery decision
+    (`delivered = [r for r in deduped if r["confidence"] >= threshold]`,
+    still the one line BEFORE_STATE.md quoted) is **unchanged** by any
+    bridge outcome — success or failure. Verified by
+    `test_bridge_disabled_delivers_identically_to_bridge_enabled_and_failing`,
+    which asserts the delivered row set is byte-identical between the two
+    paths.
+  - **Advisory only, and this is a real constraint, not an excuse:** true
+    per-row gating against the TS `ExpectationEngine` is not implementable
+    today because `ExpectationEngine` returns dataset-level pass/fail counts
+    and sample rows, not a per-row boolean array keyed to the Python
+    pipeline's record identity. Building that would mean changing
+    `ExpectationEngine`'s contract — out of scope for this pass, documented
+    rather than faked with a fabricated per-row mapping.
+- **Live-verified end-to-end** (2026-09-01, this pass): a real `next dev`
+  server (`AUTH_ENFORCE=false` for the local run only) plus the real Python
+  pipeline hitting the real `brreg.no` API, round-tripping through the real
+  `bridge-run` route, and receiving a real `QualityService` score back — not
+  a contract double on either side. This was a manual verification run
+  during development; it is not itself a repeatable automated test (the
+  pytest suite below covers the same code paths against `respx`-mocked
+  bridge responses, which *is* repeatable and is what CI would run).
+
+**What is still NOT true, stated plainly:** the bridge is **not enabled in
+production and this pass does not enable it.** `OPT_QUALITY_BRIDGE_ENABLED`
+stays unset/`false` as shipped. Turning it on is a separate, deliberate
+decision — see §4 "Activating the bridge" below. Until that decision is
+made, the two runtimes' QA logic remains exactly as split as BEFORE_STATE.md
+described: Python's one-line confidence filter is what actually decides
+delivery; the TS `QualityService`/`ExpectationEngine` only sees a
+*copy* of the same data, advisory-only, and only when the flag is on.
+
+### §3 Provenance fields — `VERIFIED` extended (Python side)
+
+`services/api/sources/connectors.py`'s `Provenance` dataclass gains, via a
+new `make_provenance()` factory used by every connector:
+`retrieved_at`, `transform`, `connector_version`, `producer`, `quality`,
+`entity_resolution`, `artifact_ref` — closing the "missing entirely from
+this struct" list BEFORE_STATE.md §3 itemized (retrieval-method-at-field-
+level remains only partially addressed: `connector_version` +`producer`
+identify *what ran*, not a full method taxonomy like the TS
+`SourceProvenance.method` enum).
+
+- `resolve.py` stamps `entity_resolution` on **merged** records' provenance
+  only (never on unmerged ones — verified by
+  `test_unmerged_record_keeps_entity_resolution_none`), tracking
+  `agreed_sources`/`merged_from` in a structured field rather than the loose
+  attribute BEFORE_STATE.md found.
+- `pipeline.py` stamps `artifact_ref` at delivery time and `quality` once
+  (if) the bridge call above succeeds.
+
+**What is still NOT true, stated plainly:** `bridge_provenance` as a single
+named construct **still does not exist** anywhere in this repo, and this
+pass does not introduce that name. What exists is still two structs — the
+Python `Provenance` dataclass (now richer) and the TS `SourceProvenance`
+type (per-source, unchanged this pass) — reconciled only at the one new
+seam described in §2 (the bridge-run response, which is advisory and
+optional). This pass closes real gaps in the Python struct; it does not
+unify the two runtimes' provenance models into one schema. Nothing here
+persists past the in-process job response either — `pipeline.py` still has
+no DB write of its own (Postgres persistence added this pass is scoped to
+the Source Registry, not to order/provenance records).
+
+### §4 Failure-mode tests — `VERIFIED` extended, with an honest residual
+
+New pytest + respx suite, `services/api/tests/`:
+
+| File | Covers |
+|---|---|
+| `test_resolve_determinism.py` | dedup-determinism under shuffled/interleaved orderings, exhaustive permutations of a mutually-similar set, duplicate-input collapsing without double-counting agreement, out-of-order multi-market arrival, entity-resolution provenance stamping — **and** an explicit, passing test of the one case BEFORE_STATE.md flagged as a real, plausible order-sensitivity risk: a non-transitive-similarity triangle in the greedy clusterer genuinely *can* cluster differently by input order. That test (`test_a_non_transitive_triangle_can_cluster_differently_by_order`) asserts the order-sensitivity, it does not paper over it — `resolve.py`'s greedy-merge algorithm was not rewritten to remove this property, since doing so is an algorithm change out of this pass's scope. |
+| `test_pipeline_fault_injection.py` | schema-evolution (upstream adding/removing/reshaping fields via respx-mocked responses through the real `brreg` connector + `pipeline.py`), restart/connector-crash resilience (a connector exception, including one raised by `respx` itself, never crashes `run_job`; every connector failing delivers zero rows, not a crash), backfill-replay (replaying the same order config is byte-identical — this is the property that actually holds given there is still no persistence layer for orders, not a fabricated "dedup store" test). |
+| `test_quality_bridge.py` | all bridge states above (disabled / not-configured / unavailable / timeout / non-2xx / malformed / connection-refused / success), plus the "wired into the pipeline" tests proving delivery is unaffected either way. |
+| `test_connectors_provenance.py` | the `make_provenance()` factory populates every new field honestly and leaves the rest `None` rather than fabricating values; a real parsing path (`brreg`) produces a fully populated provenance record. |
+| `test_known_gaps.py` | **2 explicit, documented skips** — not silently dropped, not faked: CDC-interruption and true delivery-store backfill idempotency are not implementable against this codebase, because **no CDC pipeline and no persistence layer for orders/deliveries exists anywhere in `services/api`.** Testing either would require building the infrastructure the test claims to fail-inject against, which is a different, larger piece of work than this pass. |
+
+Net: of BEFORE_STATE.md §4's four **entirely absent** categories
+(schema-evolution, CDC-interruption, out-of-order, dedup-determinism), three
+are now genuinely covered (schema-evolution, out-of-order,
+dedup-determinism) and one (CDC-interruption) is honestly documented as not
+implementable rather than covered. Tenant-isolation (already the
+best-covered category) is untouched by this pass. Quality-gate coverage
+gains the bridge-interaction tests above but the production Python filter
+itself (`delivered = [...]`) still has no line-level unit test isolated
+from an end-to-end pipeline run — this pass tests it via the fault-injection
+and bridge suites' end-to-end assertions, not a standalone unit test of that
+one line.
+
+### §5 1P/ST0RE/N0D/AUD0/CL0UD integration — unchanged this pass
+
+Not touched. BEFORE_STATE.md's classification stands: ST0RE + N0D
+real-contract (ST0RE live-verified once, historically); AUD0 real-contract
+client but unused by the live Python pipeline (still true — `quality_bridge.py`
+does not emit AUD0 events, and neither does the rest of `services/api`);
+CL0UD real-contract but not platform-wide-enforced; 1P documented-only.
+

+
+## 2. Testing — from-scratch verification (this pass, not a rerun)
+
+To avoid reporting numbers from the working tree that built the branch, this
+verification was run against a **fresh `git clone`** of the pushed branch
+(`feat/p010-data-os-completion` @ `9740e20`) in an isolated directory, with a
+fresh `pnpm install --frozen-lockfile` and a fresh Python venv — no reuse of
+node_modules, .next cache, or an existing venv from development.
+
+| Check | Result | Note |
+|---|---|---|
+| `pnpm install --frozen-lockfile` | OK | lockfile v9, no resolution drift |
+| `pnpm run typecheck` (`tsc -p tsconfig.check.json`, **CI-blocking**) | **0 errors** | Clean on the pristine clone. The working directory this branch was developed in separately contains 5 **untracked, uncommitted** paths (`src/fleet/`, `src/graph/`, `src/metrics/`, `src/projections/`, `src/features/feature-registry.ts`) that were already present and flagged, unaudited, in `BEFORE_STATE.md` before this pass started. They are not part of any commit on this branch or on `main` — confirmed by `git diff --stat origin/main..feat/p010-data-os-completion` touching none of them, and by their total absence from the fresh clone. Running `pnpm typecheck` inside the *original, non-clean* working directory does surface 14 TS errors from those 5 stray local files; that is local working-tree litter, not something CI or a fresh clone will ever see, and this pass does not touch, fix, or commit any of those files. |
+| `pnpm run test` (vitest, **CI-blocking**) | **256/256 passed, 18 skipped** (34 files passed, 3 files skipped) | Skips are the pre-existing `.realinfra`/`.integration` suites that self-skip honestly when no live ST0RE/OpenSearch/ClickHouse is reachable from this environment (`[realinfra] ST0RE ... not reachable this run (HTTP 401) -- skipping honestly, not fabricating success` — actual stderr from this run). 249 of the 256 predate this branch; 7 are new (`tests/p0/quality-bridge.test.ts`). |
+| `pnpm run lint` (eslint, **advisory in both CI workflows, `continue-on-error`**) | 12 errors / 4 warnings, **zero of them in files this branch touches** | Verified two ways: (a) `git diff --stat origin/main..feat/p010-data-os-completion` on every flagged file returns no output — byte-identical to `main`; (b) ran `pnpm lint` against a worktree checked out at `origin/main` directly and got the identical 12/4. This is 100% pre-existing legacy noise (mostly `@typescript-eslint/no-explicit-any` in v0-generated adapters/tests), not introduced or worsened by this pass. |
+| `pnpm run build` (`next build`, **CI-blocking in `.gitea/workflows/ci.yml`**; not run by `.github/workflows/ci.yml`, which needs runtime secrets Vercel owns) | **Succeeded** | Route manifest confirms the new surface is actually built: `/api/0pt/quality/{bridge-run,issues,rules,rules/[ruleId],runs,runs/[runId]}` and `/api/0pt/sources/{route,[sourceId],[sourceId]/{freshness,health,provenance,rights}}` all present as dynamic (`ƒ`) routes in the build output. |
+| `python -m pytest -v` (`services/api`, fresh venv from `requirements-dev.txt`) | **28 passed, 2 skipped** | The 2 skips are `test_known_gaps.py`'s documented CDC/backfill-idempotency gaps (§4 above) — `pytest.skip(reason=...)`, not silent omission. **Not currently wired into either `.gitea/workflows/ci.yml` or `.github/workflows/ci.yml`** — both CI workflows' own comments say the Python engine "is gated separately if/when a Python workflow is added." This pass did not add that workflow (out of P010's stated scope); the 28/28 above is a manual verification, not an automated CI gate today. Flagging this explicitly as a residual gap, not glossing over it. |
+
+**Net CI-blocking-gate status: all green** (typecheck, vitest, `next build`
+in Gitea CI; typecheck + vitest in the GitHub CI mirror). Lint is advisory
+everywhere and pre-existing failures are unrelated to this branch. Python
+tests are green but not yet gated by any CI workflow — see the Gap list
+below.
+
+---
+
+## 3. Files changed (47 files, +3119/-201, base `origin/main` → `9740e20`)
+
+New route surface: `app/api/0pt/quality/{bridge-run,issues,rules,rules/[ruleId],runs,runs/[runId]}/route.ts`,
+`app/api/0pt/sources/{route.ts,[sourceId]/route.ts,[sourceId]/{freshness,health,provenance,rights}/route.ts}`.
+New Python: `services/api/workers/quality_bridge.py`, `services/api/pytest.ini`,
+`services/api/requirements-dev.txt`, `services/api/tests/test_{connectors_provenance,known_gaps,pipeline_fault_injection,quality_bridge,resolve_determinism}.py`.
+New TS repositories/migration: `src/repositories/*` (7 files), `sql/002_source_registry.sql`.
+New TS quality bridge: `src/quality/quality-bridge.ts`, `src/services/quality.ts`, `src/services/source-registry.ts`.
+Modified: `services/api/sources/connectors.py`, `services/api/workers/{pipeline,resolve}.py`,
+`src/services/{source-registry-service,source-service,source-rate-policy-service}.ts`,
+`src/validation/0pt-schemas.ts`, `src/http/siax-error-response.ts`, `.gitignore`
+(added `.venv/`, `.pytest_cache/`), `sql/004_iceberg_write_boundary.sql` (minor).
+Test files modified: `tests/p0/source-registry.test.ts` (repointed at shared
+singleton), new `tests/p0/quality-bridge.test.ts`,
+`tests/p0/source-registry-postgres.realinfra.test.ts`.
+
+No changes to: `services/scrapers/` (the still-unmerged WAF-bypass deletion
+PR — untouched, not this pass's scope), the `app/`-root Next.js UI pages
+(`bestall/`, `katalog/`, `portal/`, etc. — untouched), any of the 5
+untracked stray paths in the working tree.
+
+---
+
+## 4. Activating the pipeline bridge — Simon's decision, not made here
+
+**`OPT_QUALITY_BRIDGE_ENABLED` ships unset (default `false`) and this pass
+does not flip it, anywhere, including in any deploy config, `.env.example`,
+or CI workflow.** This affects real customer orders once on — enabling it
+in production is a separate decision, deliberately left to Simon.
+
+To turn it on later, the following must all be true first (this pass built
+the mechanism, not the readiness):
+
+1. `OPT_QUALITY_BRIDGE_URL` (or `OPT_QUALITY_BRIDGE_EDGE_URL`, per
+   `quality_bridge.py`'s `_bridge_url()`) must point at a reachable,
+   authenticated `0pt.app` deployment — the Python engine and the Next.js
+   edge app are typically different deploy targets (VPS vs. Vercel/SIAX
+   Deploy Platform per the `siax-0pt` skill's two-plane model), so this is a
+   real cross-service network dependency, not a same-process flag flip.
+2. Even fully enabled and reachable, the bridge remains **advisory-only by
+   design** — it stamps a `quality` field on delivered provenance and
+   surfaces a score; it does **not** and, per §2's `ExpectationEngine`
+   contract gap, currently **cannot** change which rows Python's
+   `delivered = [...]` line keeps or drops. Anyone enabling the flag
+   expecting stricter row-level gating will not get it from this code as
+   shipped — that would require the `ExpectationEngine` contract change
+   noted above, which is future work.
+3. Recommended rollout, not yet executed: enable against one non-production
+   tenant/order first, confirm `bridge-run` round-trips correctly (the
+   manual live-verification in §1/§2 above did this once, ad hoc, during
+   development — it was not repeated against a staging environment as a
+   formal rollout step), then decide with Simon whether "advisory-only,
+   fails open" is the intended production posture or whether the per-row
+   gating gap needs to close first.
+
+**This pass leaves the flag off. No default, config file, or workflow in
+this PR turns it on.**
+
+---
+
+## 5. Residual gaps (honest, not exhaustive elsewhere in this doc)
+
+- Python engine tests (28/28) are not wired into either CI workflow yet —
+  a `.gitea/workflows/`/`.github/workflows/` Python job is future work, not
+  part of this pass.
+- `bridge_provenance` as a single unified construct still does not exist;
+  this pass narrows but does not close the TS/Python provenance-schema gap
+  (§3 above).
+- Per-row quality gating from the TS engine into the Python pipeline is not
+  implementable against the current `ExpectationEngine` contract (§2, §4
+  above) — advisory-only is the ceiling of what this pass could honestly
+  build, not a corner cut.
+- `resolve.py`'s greedy merge remains genuinely order-sensitive for
+  non-transitive-similarity triangles — tested and documented, not fixed
+  (fixing it is an algorithm change, out of scope here).
+- CDC-interruption and true delivery-store backfill-idempotency tests remain
+  unimplementable because the underlying infrastructure (a CDC pipeline, a
+  delivery persistence store) does not exist anywhere in `services/api` —
+  documented via `pytest.skip` with reasons in `test_known_gaps.py`, not
+  silently dropped.
+- 5 untracked/unaudited local paths (`src/fleet/`, `src/graph/`,
+  `src/metrics/`, `src/projections/`, `src/features/feature-registry.ts`)
+  remain exactly as found — not committed, not deleted, not audited by this
+  pass. They are not part of this PR's diff and a fresh clone never sees
+  them.
+- `services/scrapers/` (WAF-bypass stack) remains on `main`, unmerged
+  deletion PR still open — unrelated to and untouched by this pass, flagged
+  again here only because `BEFORE_STATE.md` flagged it and it has not
+  changed.
+
+---
+
+## 6. Process notes
+
+- No PR was open before this pass; one was opened as part of this pass (see
+  PR URL reported separately / in `PRODUCTION_EVIDENCE.json`).
+- `BEFORE_STATE.md` and the 5 pre-existing untracked/unaudited paths were
+  left untouched and uncommitted throughout, exactly as found at the start.
+- `.venv/` and `.pytest_cache/` (both created fresh under `services/api/`
+  while running the Python suite) were added to `.gitignore` so they are
+  never accidentally committed; no leftover Python processes.
+- The `next dev` server and any background verification process used for
+  the live end-to-end bridge check (§1/§2) were both confirmed stopped
+  before this pass ended — no lingering listeners.
