Its rule is **implication, not equality** — +derivation is deliberately *more* informative than the scalar (a file can be `metadata`-done *and* +`analyze`-done, which no single enum value encodes). + +**Requirements:** MIG-02. + +**Purely a verification/harness deliverable.** No reader or writer cuts over to the derived model +in this phase; no schema change. Cutover begins Phase 80. + + + +## Implementation Decisions + +### Check form & harness (D-01, D-02) +- **D-01:** **One shared assertion core** (the invariant set + comparison logic authored once) exposed + through **two entry points** — (a) a **hermetic pytest** over a crafted **fixture corpus** in the + `integration` bucket, which is the **standing CI gate** phases 80–90 keep green, and (b) a thin + **`just shadow-compare`** CLI/module that runs the *same core* against any DB it is pointed at + (a live-corpus restore). No assertion logic is duplicated between the two. (Rejected pytest-only — + no first-class live-DB path; and CLI-only — needs extra fixture-DB plumbing for CI.) +- **D-02:** The **live 200K-corpus restore run is deferred** to the next homelab rollout and recorded + in the phase VERIFICATION when performed (consistent with this project's other deployment-gated UAT + items). This phase ships the check + hermetic fixture tests **green**. The gate remains a hard + precondition for `033` (phase 90) regardless of when the live run happens. + +### Derived-side source (D-03) +- **D-03:** The "derived representation" side of the comparison is built by **reusing Phase 78's + predicates** — `services/stage_status.py` `ColumnElement[bool]` builders / `enums/stage.py` resolver. + The gate therefore **doubles as a guard on the derivation layer** — the exact predicates phases 80–90 + cut over to. The residual circularity is acceptable and understood: `032` backfilled the + `DUPLICATE_RESOLVED` / failure / cloud-sidecar markers *from* `files.state`, but `ANALYZED` / + `METADATA_EXTRACTED` / `PROPOSAL_GENERATED` / apply-outcome states derive from **pre-existing output + rows**, so the gate still catches real state↔data drift. (Rejected independent raw-column SQL — it + duplicates predicate logic and would not guard the derivation layer the later phases depend on.) + +### Invariant scope (D-04) +- **D-04:** **Comprehensive** — assert an implication for **every `FileState` value** in the design + §6.1 table, not just the ~6 risky/backfilled ones. This includes the "no-backfill" completion states: + - `ANALYZED ⇒ analysis.analysis_completed_at IS NOT NULL` + - `METADATA_EXTRACTED ⇒ metadata row exists` + - `ANALYSIS_FAILED ⇒ analyze failure marker exists` + - `DUPLICATE_RESOLVED ⇒ dedup marker exists` + - `AWAITING_CLOUD ⇒ cloud sidecar row exists` + - `PUSHING`/`PUSHED ⇒ cloud_job row with the corresponding status` + - `PROPOSAL_GENERATED ⇒ proposals row`; `APPROVED`/`REJECTED ⇒ proposals.status`; + `EXECUTED`/`MOVED`/`UNCHANGED`/`FAILED ⇒ execution_log + proposals.status` + Rationale: this is *the* gate before dropping the column — a completion state with no backing row is + exactly the drift worth catching. (Rejected the risky-subset-only option.) + +### Divergence output & fail semantics (D-05, D-06) +- **D-05:** Output = **per-invariant divergent-file count + a capped sample of `file_id`s** (e.g. first + 20) so an operator can investigate without a full dump, plus a totals line. Any hard-fail divergence + → **nonzero exit code / pytest failure**. A `--verbose`/`--dump` flag emits the full divergence set on + demand. (Rejected always-full-dump — noisy at 200K scale; and count-only — forces a manual re-query + to find offenders.) +- **D-06:** The two known-soft divergences are an **explicit, code-commented allowlist** referencing + design §6.1: **`FINGERPRINTED`** (documented-expected — its only writer is + `routers/pipeline.py:935` `retry_analysis_failed`, so it need not imply a fingerprint success) and + **`LOCAL_ANALYZING`** (design D-03 "probably no stored marker").

(Rejected always-full-dump and count-only.) +- **D-06:** The two known-soft divergences are an explicit, code-commented allowlist referencing design §6.1: **`FINGERPRINTED`** (its only writer is `routers/pipeline.py:937` `retry_analysis_failed`, so it need not imply a fingerprint success) and **`LOCAL_ANALYZING`** (design "probably no stored marker").

The deliverable is one **shared assertion core** that, for each legacy `FileState` value, runs a corpus-wide **anti-join** (`WHERE state = X AND NOT ()`) and reports the count + a capped sample of divergent `file_id`s. It runs from two entry points against the *same* core: a hermetic pytest in the `integration` bucket (the standing CI gate) and a `just shadow-compare` CLI pointed at any DB. + +The single most important architectural fact: **the derived side must reuse `services/stage_status.py`'s `done_clause(stage)` / `failed_clause(stage)` builders directly — NOT `stage_status_case(stage)`.** The CASE ladder puts `in_flight ≻ done`, so a file that is legitimately `ANALYZED` *and* has a queued re-analysis (scheduling-ledger row) would resolve to `in_flight` under the ladder and falsely flag as divergent. The gate asserts membership implications (`state=X ⇒ done(...)`), which map to the un-laddered `done_clause`/`failed_clause` correlated `exists()` predicates. This is the "implication, not equality" contract at the SQL level. + +The second fact: **Phase 78 covers only ~half the invariants.** The enrich-completion states (METADATA_EXTRACTED, ANALYZED, ANALYSIS_FAILED, PROPOSAL_GENERATED) and the execution_log apply outcomes reuse Phase-78 clauses cleanly and are the *real* drift-catchers (they derive from pre-existing output rows). But the cloud-sidecar states (AWAITING_CLOUD/PUSHING/PUSHED), DUPLICATE_RESOLVED, and the proposal-status states (APPROVED/REJECTED and the MOVED/UNCHANGED apply-outcome status) have **no Phase-78 predicate** and must be asserted with raw ORM columns. Those raw-column invariants are near-tautological on a freshly-`032`-backfilled corpus (the row was created *from* the state) — that is the accepted D-03 circularity, and it must be called out in the check's docstring. + +**Primary recommendation:** Author one module `src/phaze/services/shadow_compare.py` exposing an `INVARIANTS` registry (name, state value, derived predicate factory, soft/hard flag, §6.1 doc-ref) + an async `run_shadow_compare(session, *, sample_cap, verbose) -> Report`. Wrap it in (a) `tests/integration/test_shadow_compare.py` (fixture corpus reusing the `test_stage_status_equivalence.py` seed pattern; one RED cell + one consistent-corpus GREEN cell per invariant, plus soft-allowlist cells) and (b) a thin `src/phaze/cli/shadow_compare.py` argparse runner invoked by a `[group('db')] shadow-compare` justfile recipe via `uv run python -m phaze.cli.shadow_compare`. + +## Architectural Responsibility Map + +| Capability | Primary Tier | Secondary Tier | Rationale | +|------------|-------------|----------------|-----------| +| Invariant definitions + divergence queries | API/Backend (`services/`) | — | Pure SQLAlchemy over the ORM models; reuses `services/stage_status.py`; no HTTP, no agent.

Reusing `done_clause(Stage.ANALYZE)` (the raw `exists(analysis_completed_at IS NOT NULL)`) sidesteps the precedence and expresses the true membership implication. +**Example:** +```python +# Source: composes phaze.services.stage_status.done_clause (Phase 78) +from phaze.enums.stage import Stage +from phaze.services.stage_status import done_clause +from phaze.models.file import FileRecord, FileState + +# state=ANALYZED ⇒ done(analyze).

Soft allowlist is a boolean field on the entry, commented back to §6.1 (D-06). +**When to use:** here — it keeps the pytest side (parametrize over `INVARIANTS`) and the CLI side (iterate `INVARIANTS`) sharing one definition (D-01 "no logic duplicated"), and makes the allowlist un-growable-by-accident (a new soft entry is a visible diff). + +### Pattern 3: count + capped-sample per invariant (D-05) +**What:** For each invariant run two cheap statements against the same anti-join predicate: `SELECT count(*)` and `SELECT id ... LIMIT sample_cap`. `--verbose` drops the LIMIT. +**Why:** avoids materializing a 200K-row divergence set; the count answers "is the gate green?", the sample answers "which files to investigate?". + +### Anti-Patterns to Avoid +- **Using `stage_status_case`/`resolve_status` for the derived side** — reintroduces `in_flight` precedence and false-flags in-flight-over-done files (Pattern 1). +- **Asserting equality (`state ⇔ derived`)** — the derivation is deliberately MORE informative than the scalar (a file can be metadata-done AND analyze-done).

The genuine drift-catchers are the pre-existing-output-row states: 2, 4, 10, 11–14, 16, 17. + +\*\* `FileState.FAILED` has zero writers in `src/` (design §4.1 item 2); its invariant is still authored (D-04 comprehensive) but will simply find zero matching-state rows. + +### Apply-outcome mapping — verified joint-write semantics +`routers/agent_proposals.py:47-49` `_FILE_FOLLOW`: `ProposalStatus.EXECUTED → FileState.MOVED`, `ProposalStatus.FAILED → FileState.UNCHANGED`, set jointly in one PATCH `[VERIFIED: src/phaze/routers/agent_proposals.py:114-116]`. Therefore the **authoritative** derived source for the apply-outcome states is `proposals.status` (design §4: "already authoritative — file state is a redundant cascade"), NOT `execution_log`. +- **Recommendation:** assert MOVED/UNCHANGED/EXECUTED/FAILED against `proposals.status` (raw `exists(RenameProposal WHERE file_id AND status=…)`), because the `execution_log` audit row can legitimately be absent (e.g. a proposal marked failed before any execution_log write) — `done_clause(APPLY)`/`failed_clause(APPLY)` go through `execution_log.status='completed'/'failed'` and would over-flag. `[ASSUMED]` that `proposals.status` is the safer target — planner should confirm during plan-check against a sampled live restore, but design §4 supports it. + +## Runtime State Inventory + +Not a rename/refactor/migration phase — this phase is an **additive verification harness** (no schema change, no data mutation, no code cutover).

(The destructive data migration is Phase 90; the additive one was Phase 77.) + +## Common Pitfalls + +### Pitfall 1: Using `stage_status_case` for the derived side +**What goes wrong:** files that are legitimately done but have an in-flight retry ledger row resolve `in_flight` under the ladder and false-flag as divergent. +**Why:** `stage_status_case` precedence is `in_flight ≻ done ≻ failed` (`stage_status.py:184-189`). +**How to avoid:** reuse `done_clause`/`failed_clause` (un-laddered correlated `exists`) — never the CASE. +**Warning sign:** a GREEN consistent-corpus fixture cell fails only when you also seed a scheduling-ledger row. + +### Pitfall 2: Asserting `DISCOVERED ⇒ no output rows` +**What goes wrong:** flags files that were rescan-wiped to `discovered` in the past (pre-Phase-77) but still carry orphaned output rows — exactly the historical drift the derivation *fixes*, not a bug. +**Why:** implication is one-directional; the derived side is deliberately more informative. +**How to avoid:** `DISCOVERED` gets NO invariant. Document it as intentionally-vacuous in the registry (a commented placeholder, not a silent gap) so "comprehensive" (D-04) is auditable. + +### Pitfall 3: `fingerprint_results.status IN` spelling / index +**What goes wrong:** a bare `status IN ('success','completed')` predicate can miss `ix_fprint_success` if spelled differently from the index's `= ANY (ARRAY[...])`. +**Why:** the partial index is `postgresql_where=text("status = ANY (ARRAY['success','completed'])")` (`models/fingerprint.py:30`). +**How to avoid:** `FINGERPRINTED` is allowlisted (never asserted), so this doesn't bite here — but if any invariant touches fingerprint success, reuse `stage_status._DONE_FP` and `.in_(_DONE_FP)` (renders `= ANY`), matching Phase-59 WR-02. + +### Pitfall 4: `execution_log` has no `file_id` +**What goes wrong:** joining execution rows to files directly fails. +**Why:** `ExecutionLog` FKs `proposal_id` only (`models/execution.py:30`). +**How to avoid:** join through `proposals` (as `done_clause(APPLY)` does) — but per the apply-outcome recommendation above, prefer `proposals.status` directly and avoid `execution_log` entirely for these invariants. + +### Pitfall 5: CLI pointed at the wrong DB / `saq_jobs` guard +**What goes wrong:** the CLI silently runs against the dev DB, or a query references `saq_jobs`. +**How to avoid:** the CLI must read a target DSN from env (`DATABASE_URL`/app settings) with an optional `--database-url` override for a restore (D-02). The gate needs NO `saq_jobs` access at all (it uses `done/failed_clause` only) — keep it that way (Alembic-banner discipline is about migrations, but staying `saq_jobs`-free here also keeps the check deterministic on a restore where the broker table may be empty/absent). + +## Code Examples + +### Reused fixture-corpus seed pattern (the hermetic gate template) +The existing DERIV-04 test is the exact template — it already seeds `FileRecord` + every output table with per-test rollback and PG-skip-if-down.

Two CLI robustness/secret-hygiene warnings follow. + +## Critical Issues + +### CR-01: Destructive `TRUNCATE agents CASCADE` runs against a DSN that defaults to the dev database + +**File:** `tests/integration/test_shadow_compare.py:57-60, 306-318, 321-343` +**Issue:** +`SA_DSN` is derived exactly like the sibling harness and falls back to the **dev** database when +no env var is set: + +```python +BROKER_DSN = (os.environ.get("PHAZE_QUEUE_URL") or os.environ.get("TEST_DATABASE_URL", + "postgresql://phaze:phaze@localhost:5432/phaze")).replace("postgresql+asyncpg://", "postgresql://") +SA_DSN = (os.environ.get("TEST_DATABASE_URL") or BROKER_DSN).replace("postgresql://", "postgresql+asyncpg://") +``` + +Per the `justfile` (lines 4-9) and `CLAUDE.md`, port **5432** is the dev DB and **5433** is the +ephemeral test DB. Unlike every sibling integration test (which is rollback-isolated via the +`db_session` fixture), this file's `cli_corpus` fixture **commits** rows (`_cli_commit_file`) and, +on teardown, **commits a destructive truncate**: + +```python +async def _cli_truncate_corpus() -> None: + ... + await conn.execute(text("TRUNCATE agents CASCADE")) # wipes agents + files + proposals + cloud_job + ... +``` + +The connectivity probe only `pytest.skip`s when Postgres is **down** — it does not check *which* +database it hit. So running the sanctioned `just integration-test` is safe (it exports +`TEST_DATABASE_URL=...localhost:5433/phaze_test`), but the command `CLAUDE.md` explicitly documents +for single-file/single-test runs — `uv run pytest tests/integration/test_shadow_compare.py` — with a +dev stack up (`just up` → Postgres on 5432) and `TEST_DATABASE_URL` unset will connect to the live +dev database and `TRUNCATE agents CASCADE`, destroying the entire dev corpus (files, proposals, +cloud_job rows, dedup markers, agents). This is a data-loss defect newly introduced by this file; +the rollback-based siblings never truncate. + +**Fix:** Refuse to run the committing/truncating CLI cells unless the target is unambiguously a +test database. Guard in `cli_corpus` before any commit/truncate: + +```python +from sqlalchemy.engine import make_url + +def _assert_test_db() -> None: + db = (make_url(SA_DSN).database or "") + port = make_url(SA_DSN).port + if not (db.endswith("_test") or port == 5433): + pytest.skip(f"refusing destructive TRUNCATE against non-test database {db!r}:{port} " + "(set TEST_DATABASE_URL to the ephemeral :5433/phaze_test DB or run `just integration-test`)") +``` + +Call `_assert_test_db()` at the top of the `cli_corpus` fixture (before `_cli_prepare_schema_and_seed_agent`). +Alternatively, scope the TRUNCATE to only the rows this fixture created rather than `CASCADE`-wiping +the whole corpus. + +## Warnings + +### WR-01: `--database-url` password leaks into stderr on any URL/engine error + +**File:** `src/phaze/cli/shadow_compare.py:59-65, 79, 95-99` +**Issue:** +The module docstring and `_safe_target` promise the DSN password is "NEVER passed to `print()` or a +logger" (T-79-04). That holds on the happy path, but the DSN reaches two error surfaces uncaught: + +- `main()` calls `_safe_target(args.database_url)` → `make_url(database_url)` (line 64/97). A malformed + DSN makes `make_url` raise `sqlalchemy.exc.ArgumentError`, whose message embeds the **full URL string + including the password** (`Could not parse SQLAlchemy URL from string '...'`). The uncaught exception + prints a traceback with the password to stderr. +- `create_async_engine(database_url)` / first connection (line 79, 82-83) can likewise raise with the + DSN in the message. + +So a fat-fingered or wrong-scheme DSN defeats the stated secret discipline. +**Fix:** Wrap URL parsing/engine construction and re-raise a redacted error: + +```python +try: + url = make_url(database_url) +except Exception as exc: # never surface the raw DSN + raise SystemExit("shadow-compare: could not parse --database-url (check scheme/credentials)") from None +``` + +Apply the same redaction around `create_async_engine` / session open in `_run`, and never let the raw +`database_url` reach an uncaught traceback. + +### WR-02: `--sample-cap` accepts negative values → Postgres `LIMIT` error + +**File:** `src/phaze/cli/shadow_compare.py:45-48`; `src/phaze/services/shadow_compare.py:216-217` +**Issue:** +The docstring advertises "`--sample-cap` is parsed as `int` … V5 input validation," but `type=int` +only rejects non-integers, not negatives. A negative cap flows into +`sample_query = sample_query.limit(sample_cap)`; Postgres rejects a negative `LIMIT` +("LIMIT must not be negative"), so `--sample-cap -1` crashes the run with a raw DB error rather than a +clean operator message. The advertised validation is incomplete. +**Fix:** Validate non-negativity at parse time: + +```python +def _nonneg_int(v: str) -> int: + n = int(v) + if n < 0: + raise argparse.ArgumentTypeError("must be >= 0") + return n + +parser.add_argument("--sample-cap", dest="sample_cap", type=_nonneg_int, default=20, ...) +``` + +## Info + +### IN-01: Unordered `LIMIT` makes the capped sample non-deterministic + +**File:** `src/phaze/services/shadow_compare.py:215-218` +**Issue:** +`select(FileRecord.id).where(condition).limit(sample_cap)` has no `ORDER BY`, so which `file_id`s land +in a capped sample is at Postgres' discretion and may vary run to run. This is harmless for the counts +(which use `func.count`) and for the current tests (rollback isolation guarantees a single divergent +row per case), but on the live corpus two consecutive operator runs can print different sample UUIDs +for the same divergence, which is confusing when triaging.

The DERIV-04 anti-drift lock is a parametrized SQL⇔Python equivalence matrix (`tests/integration/test_stage_status_equivalence.py`, 25 cases, real PG green via `just test-bucket integration`) asserting `sql_status == py_status == expected` for every (stage × status) cell; 44 DB-free unit cells in `tests/shared/`.

MIG-02's deliverable — *a committed, re-runnable shadow-compare check* — is fully built and verified. The live 200K-corpus restore run (ROADMAP Success Criterion 3) is NOT a Phase-79 deliverable gap: it is an OPERATIONAL precondition for Phase 90's destructive `033`, deliberately scoped out of this phase by decision D-02 (no live dump exists in this worktree).

After the user elected to mark Phase 79 complete with that item tracked as a deferred operational precondition, this report was reconciled to `status: passed` so the three tracking artifacts agree (ROADMAP `[x]` + REQUIREMENTS `MIG-02 Complete` + VERIFICATION `passed`) — which the `test_requirements_traceability` drift guard (DOCS-01) requires. The deferred live-corpus run is preserved verbatim below and in `deferred_manual_verification` frontmatter; it is non-blocking for phase closure but blocking for Phase 90. ### Observable Truths From 40ce2010f141ab2ca35b7697980c73df664fb691 Mon Sep 17 00:00:00 2001 From: Robert Wlodarczyk Date: Wed, 8 Jul 2026 14:44:24 -0700 Subject: [PATCH 28/28] test(79): cover CLI validation/redaction/default-session branches (coverage floor) CI per-module coverage floor (90%) failed on cli/shadow_compare.py at 87.76%: the integration CLI-exit cells always pass --database-url, leaving the argparse-negative-cap, DSN-redaction, and default-async_session branches uncovered. Adds a DB-free hermetic unit file in the shared bucket exercising those branches (monkeypatched core, no PG/network) and pragmas the __main__ guard. Combined shared+integration coverage of the module is complete; the two buckets' missing sets are disjoint. 8 new cells pass; hermetic in both orderings.
