Everything the plan needs is already precedented in-tree and every locked decision (D-01..D-04) maps onto an existing idiom: the `begin_nested()` SAVEPOINT degrade pattern (seven verbatim occurrences in `pipeline.py`/`review.py`/`reenqueue.py`), the `~exists(...)` anti-join (`get_untracked_files`), the deterministic `":"` ledger key (`deterministic_key._KEY_BUILDERS`), and the Phase 77 partial indexes (`ix_analysis_completed`, `ix_analysis_failed`, `ix_metadata_failed`, `ix_fprint_success`) that already exist and are shaped to exactly these predicates. **Zero new dependencies.** + +Three findings materially shape the plan and are **not** obvious from CONTEXT.md. **(1)** SQLAlchemy has **no supported facility to evaluate a `ColumnElement[bool]` against a plain-Python row** — the private `sqlalchemy.orm.evaluator._EvaluatorCompiler` (which backs `synchronize_session="evaluate"`) does not reliably support `IS NOT NULL` / `= ANY(ARRAY[...])` and is internal API. "Authored exactly once" (DERIV-01/SC#2) therefore means the SQL builder is written once *and never duplicated across callers*; the Python resolver is a deliberate hand-written twin, and the **DERIV-04 parametrized equivalence test is the real lock** (exactly as D-04 states). **(2)** `execution_log` has **no `file_id`** — it references `proposal_id` only `[VERIFIED: models/execution.py:30]`. Any predicate touching `execution_log` (the downstream `apply` stage) must join through `proposals`; `done(apply)` cannot be a bare `EXISTS execution_log`. **(3)** `generate_proposals` is keyed by an **order-independent set-hash of `file_ids`**, not per file `[VERIFIED: deterministic_key.py:85]` — so `in_flight(propose, file)` is **not derivable from a per-file ledger key**. The three enrich stages (the ELIG-01 target) and `search_tracklist`/`push_file` are all file-keyed and derive cleanly; downstream `propose` in-flight is a genuine gap to flag (acceptable for additive Phase 78 since ELIG-02 defines downstream eligibility purely as upstream conjuncts). + +**Primary recommendation:** Author each stage's `done`/`failed` predicate as a `ColumnElement[bool]` builder in `services/stage_status.py` (the single SQL source of truth) and its scalar twin in the `enums/stage.py` resolver; derive `in_flight` from a `scheduling_ledger` row-exists on key `f"{STAGE_TO_FUNCTION[stage]}:{file_id}"` (D-01 authoritative), with a SAVEPOINT-wrapped `saq_jobs` read that only enriches queued-vs-active detail (D-02). Use `EXISTS`/`~exists` (never `LEFT JOIN..IS NULL`, never `NOT IN`) for the fingerprint 1:N aggregation and every anti-join. Lock SQL⇔Python with a parametrized fixture matrix in the `integration` bucket; put the ELIG-03 terminal-failed-analyze regression and the DB-free resolver tests in `shared`. + + +## User Constraints (from CONTEXT.md) + +### Locked Decisions +- **D-01 (INFLIGHT-03 — the required written decision record):** `in_flight(file, stage)`'s authoritative source is the **`scheduling_ledger`** — a ledger row for the `(file, stage-function)` key means `in_flight`. `saq_jobs` is a **corroborating signal only**, not authoritative. Rationale: the ledger is written at the same single `before_enqueue` chokepoint that creates the `saq_jobs` row (so `ledger ⊇ saq_jobs` keys in the normal path), it is **durable** (survives a broker truncate/restore and outlives a crashed job's lost `saq_jobs` row), and it decouples the hot 5s `/pipeline/stats` poll from live-broker coupling. Satisfies the safety property: a crashed-mid-run / callback-lost file keeps its ledger row and reads `in_flight`, never falsely `not_started` (guards the 44.5K over-enqueue class). Chosen over the strict **ledger-alone** (loses the corroboration hook) and the **`saq_jobs ∪ scheduling_ledger` union** (makes the live broker load-bearing on the hot path, enlarges the false-positive-stuck set). +- **D-02 (INFLIGHT-02):** The **`in_flight` boolean = a ledger row exists** — full stop. This is also the **degrade-safe default**: the `saq_jobs` read is static SQL wrapped in a `begin_nested()` SAVEPOINT, used **only** to enrich observability / DAG busy pills with queued-vs-active detail; it **never flips the boolean**. On ANY `saq_jobs` error, drop the detail and keep `in_flight` from the ledger. `/pipeline/stats` never 500s on a broker read hiccup; Alembic never references `saq_jobs`. +- **D-03 (DERIV-03):** `done(metadata)` = a `metadata` row is present **AND `failed_at IS NULL`.** Honors the Phase 77 D-02 handoff (a metadata failure inserts a row with `failed_at` set → a failure-only row derives NOT-done → failed). Additive-safe today (Phase 77 skipped the metadata backfill, so every existing row has `failed_at = NULL`).

The SQL side is a `ColumnElement[bool]` builder in `stage_status.py`, imported by every caller (so it is never re-spelled across `pipeline.py`, `reenqueue.py`, etc. in later cutover phases). The Python side is a hand-written twin in the DB-free resolver. + +**Why not literally one function:** SQLAlchemy exposes **no supported API to evaluate a `ColumnElement[bool]` against a plain-Python row** (see Pitfall 1). The idioms genuinely diverge — `AnalysisResult.analysis_completed_at.isnot(None)` vs Python `completed_at is not None`; `status = ANY(ARRAY[...])` vs `any(s in _DONE_FP for s in statuses)`. D-04 anticipates exactly this: "the test is authoritative where they diverge (`IS NOT NULL`, `IN (...)`)." + +**Recommended SQL builder shape** (correlated `EXISTS`, so it composes into any `select(FileRecord).where(...)`): +```python +# services/stage_status.py — Source idiom: pipeline.py:1388 (~exists), :1420 (exists+isnot) [VERIFIED] +from sqlalchemy import ColumnElement, exists, select +from phaze.models.analysis import AnalysisResult + +def analyze_done_clause() -> ColumnElement[bool]: + return exists( + select(AnalysisResult.id).where( + AnalysisResult.file_id == FileRecord.id, + AnalysisResult.analysis_completed_at.isnot(None), # NOT bare row existence (DERIV-03) + ) + ) +``` + +**Recommended Python resolver shape** (scalars only — a compute agent passes a dict it already has): +```python +# enums/stage.py — DB-FREE. No phaze.models import (test_task_split boundary). +def _analyze_status(*, completed_at, failed_at, inflight: bool) -> Status: + if inflight: return Status.IN_FLIGHT # precedence ladder (DERIV-02) + if completed_at is not None: return Status.DONE + if failed_at is not None: return Status.FAILED + return Status.NOT_STARTED +``` + +### Pattern 2: The precedence ladder (`in_flight ≻ done ≻ failed ≻ not_started`) + +Both forms evaluate the SAME 4-way ladder. SQL is a `case()`: +```python +# services/stage_status.py +from sqlalchemy import case +def analyze_status_case() -> ColumnElement[str]: + return case( + (inflight_clause("analyze"), "in_flight"), + (analyze_done_clause(), "done"), + (analyze_failed_clause(), "failed"), + else_="not_started", + ) +``` +The equivalence test compares this label to `resolve_status(...)`'s `.value`. Precedence is load-bearing: a file that failed then was manually re-enqueued has BOTH a `failed_at` and a live ledger row → must read `in_flight`, not `failed`. + +### Pattern 3: Fingerprint 1:N `done` via `EXISTS(success)` (DERIV-05) + +`fingerprint_results` is **1:N** — unique on `(file_id, engine)`, not on `file_id` `[VERIFIED: fingerprint.py:26]`. A file has one row per engine (e.g. audfprint + panako). `done(fingerprint)` = **any** engine succeeded: +```python +def fingerprint_done_clause() -> ColumnElement[bool]: + return exists( + select(FingerprintResult.id).where( + FingerprintResult.file_id == FileRecord.id, + FingerprintResult.status.in_(("success", "completed")), # SA renders = ANY(ARRAY[...]) + ) + ) +``` +Python twin over the list of engine statuses: +```python +_DONE_FP = frozenset({"success", "completed"}) +def _fp_status(*, engine_statuses: list[str], inflight: bool) -> Status: + if inflight: return Status.IN_FLIGHT + if any(s in _DONE_FP for s in engine_statuses): return Status.DONE # one success wins (DERIV-05) + if any(s == "failed" for s in engine_statuses): return Status.FAILED + return Status.NOT_STARTED +``` +The DERIV-05 fixture (`[success, failed]` → `done`) is the exact aggregation guard. This reuses the Phase-59 WR-02 `status IN ('success','completed')` spelling (PR #189) `[VERIFIED: pipeline.py get_fingerprint_pending_files uses status=="failed"; ix_fprint_success uses = ANY(ARRAY['success','completed'])]`. + +### Pattern 4: Terminal failed-analyze at the shared predicate (ELIG-03) + +`eligible(analyze)` = `NOT done AND NOT in_flight` **AND NOT failed** — a failed analyze must be structurally absent from the eligible/pending set. This mirrors the existing recovery precedent verbatim: `_select_done_analyze_ids` treats `ANALYSIS_FAILED` as analyze-**DONE** so `recover_orphaned_work` never auto-loops an un-analyzable file; the operator-gated `POST /pipeline/analysis-failed/retry` flips the file OUT of the failed state before re-enqueue `[VERIFIED: reenqueue.py:177-187]`. In the derived model the equivalent is: `eligible(f, "analyze") = analyze_status(f) == NOT_STARTED` (since `done`/`failed`/`in_flight` all exclude it). ELIG-04's fingerprint contrast: `done(fp)=EXISTS(success)`, so a failed-only fingerprint file is NOT done → with no in-flight it stays eligible (auto-retry preserved). + +### Pattern 5: `in_flight` from the ledger key (D-01, INFLIGHT-01) + +The scheduling-ledger PK is the deterministic `":"` key `[VERIFIED: scheduling_ledger.py:59, deterministic_key.py:116]`.

Keep the two files tiny and side-by-side so a reviewer sees both halves of each predicate. +**Warning signs:** any import of `sqlalchemy.orm.evaluator`; a resolver that constructs SQLAlchemy objects. + +### Pitfall 2: a plain `session.rollback()` on the degrade path 500s the poll +**What goes wrong:** Wrapping the `saq_jobs` read in `try/except` + `await session.rollback()` recovers the aborted transaction but **expires every already-loaded ORM object** on the session; the next lazy attribute access on the dashboard's `agents`/`recent_scans` raises and the 5s `/pipeline/stats` poll 500s. +**Why it happens:** SQLAlchemy expires all instances on `rollback()`; `begin_nested()` (SAVEPOINT) rolls back only the nested scope. +**How to avoid:** Use `async with session.begin_nested():` verbatim (Pattern 6).

Low risk — the equivalence test remains correct either way; it just becomes belt-and-suspenders. | +| A2 | For additive Phase 78, `eligible(propose)` need not include an `in_flight` term (ELIG-02 defines it as `done(metadata) AND done(analyze)`), so the batch-keyed-ledger gap (Pitfall 5) is deferrable. | Pattern 5 / Open Q1 | If the planner wants propose in-flight now, a non-per-file mechanism (probe `saq_jobs` for any `generate_proposals` key containing the file — expensive) is needed. Recommend deferring to the cutover phase. Flag at discuss/plan time. | +| A3 | The `done(review)`/`done(apply)` semantics (review = proposal exists; apply = approved proposal / completed execution_log) match ELIG-02's wording and the Phase-85/86 intent. | Per-Stage table | If review "done" should mean "a decision was made" (approved OR rejected) rather than "a proposal exists," the review predicate shifts. ELIG-02 says "a proposal exists"; carried as-is. Confirm with planner. | +| A4 | `MUSIC_VIDEO_TYPES` file-type gating (the metadata/tracklist pending sets) is the correct population filter to mirror in the derived eligibility, i.e. non-music files are simply never eligible for enrich stages. | Eligibility table | If a companion/non-media file should surface, the filter differs. Matches `get_metadata_pending_files` exactly `[VERIFIED]`. Low risk. | + +## Open Questions + +1. **`in_flight(propose)` from a batch set-hash key.** + - What we know: enrich stages + `search_tracklist` + `push` are file-keyed and derive cleanly; `generate_proposals` is keyed on `sha256(sorted file_ids)` `[VERIFIED]`. + - What's unclear: whether Phase 78 must expose a per-file `in_flight(propose)` at all. + - Recommendation: **No.** ELIG-02 defines propose eligibility as `done(metadata) AND done(analyze)`; scope `in_flight` derivation to file-keyed stages and document the limitation. The reader-cutover phase can decide whether propose needs an in-flight guard (likely via `saq_jobs` batch-membership at that point). + +2. **`done(review)` — "proposal exists" vs "decision made".** + - What we know: ELIG-02 says review-eligible = "a proposal exists"; a separate "done(review)" is not explicitly required by DERIV-03 (review is not an output-table stage the way metadata/analyze are). + - Recommendation: model `review` eligibility as `exists(proposal)` and treat `apply` as the terminal output stage (`execution_log` through `proposals`). Confirm the exact review/apply status semantics with the planner; they harden in Phases 85/86. + +## Environment Availability + +| Dependency | Required By | Available | Version | Fallback | +|------------|------------|-----------|---------|----------| +| PostgreSQL (ephemeral) | DERIV-04 equivalence test + INFLIGHT-02 SAVEPOINT test | ✓ via `just test-db` / `just integration-test` | 16+ container (`:5433`) | Connectivity-probe `pytest.skip` `[VERIFIED: conftest.py:117]` | +| `saq_jobs` table | INFLIGHT-02 SAVEPOINT-degrade test | ✓ auto-created on `queue.connect()` | — | drop-table sub-case exercises the degrade path | +| sqlalchemy / asyncpg / pytest-asyncio | modules + tests | ✓ (`uv sync`) | 2.0.51 / installed | — | + +**Missing dependencies with no fallback:** none. +**Missing dependencies with fallback:** none — all in the existing stack. + +## Validation Architecture + +### Test Framework +| Property | Value | +|----------|-------| +| Framework | pytest + pytest-asyncio (`uv run pytest`) | +| Config file | `pyproject.toml` (`[tool.pytest.ini_options]`) + `tests/buckets.json` per-bucket isolation | +| Quick run command | `uv run pytest tests/shared/test_stage_resolver.py -x` (DB-free, fast) | +| Full suite command | `just integration-test` (ephemeral PG `:5433` for the equivalence + SAVEPOINT tests) | +| Buckets | **`shared`** for the DB-free resolver/DAG/ELIG-03 tests; **`integration`** for the real-PG DERIV-04 equivalence + INFLIGHT-02 degrade test.

The phase is purely additive — no reader/writer is wired to these builders, so nothing ships broken. The three hard contracts hold: + +- **DB-free boundary:** `enums/stage.py` imports only `enum` + `typing`; the subprocess guard in `test_stage_resolver.py` enforces it. Verified — no `phaze.models` / `phaze.database` / `sqlalchemy` in the import graph. +- **`saq_detail` SAVEPOINT + static SQL:** `_SAQ_DETAIL_SQL` is a static `text()` with a literal status allowlist, no interpolation, run inside `session.begin_nested()`, degrade-safe on any `Exception`. Verified — no injection surface. +- **`in_flight` from `scheduling_ledger`:** `inflight_clause` probes `SchedulingLedger.key` on the deterministic `":"` key via `STAGE_TO_FUNCTION`; `saq_jobs` is read-only/detail-only and never flips the boolean. Verified. + +The DERIV-04 equivalence harness genuinely covers the matrix cells it enumerates, and the SQL/Python twins agree on every covered cell. **No BLOCKER-class defect** (no security, data-loss, or ships-broken issue). Findings are latent-logic gaps and drift/maintainability hazards, several of which matter because this layer exists specifically to guard the 44.5K over-enqueue class. + +## Warnings + +### WR-01: `done(review)` is coextensive with `done(propose)` — review eligibility is unreachable, and the unit test masks it with an impossible status map + +**File:** `src/phaze/services/stage_status.py:107-109`, `src/phaze/enums/stage.py:127-128,192-193`, `tests/shared/test_stage_eligibility_dag.py:123-126` + +**Issue:** For both `PROPOSE` and `REVIEW`, `done_clause` returns the identical predicate `exists(RenameProposal WHERE file_id == FileRecord.id)`, and the Python twin resolves both from the same `row_present = (any proposal exists)` scalar. So whenever `PROPOSE` derives `DONE`, `REVIEW` derives `DONE` too — they can never differ. But `eligible(REVIEW)` (the generic downstream branch) requires `status_map[PROPOSE] == DONE AND status_map[REVIEW] != DONE`. Under real derived status those two conditions are mutually exclusive, so `eligible(status_map, REVIEW)` is **always `False`** once wired to derived rows. The passing unit test `test_review_requires_proposal_exists` hides this by hand-constructing `{PROPOSE: DONE}` with `REVIEW` absent (defaulting to `NOT_STARTED`) — a status map that can never arise from `resolve_status`, giving false confidence that the review gate fires. This is the open assumption RESEARCH A3 explicitly flagged ("If review 'done' should mean 'a decision was made' … the predicate shifts … Confirm with planner") carried as-is. + +**Fix:** Confirm the intended review semantics with the planner before cutover. If review-eligible means "a proposal awaits a decision," `done(review)` should mean "a decision was made" (`status IN ('approved','rejected')`), distinct from `done(propose)` = "a proposal exists"; then add an equivalence-matrix cell where `PROPOSE=DONE` but `REVIEW≠DONE` so the divergence is actually exercised. If the current coextensive semantics are truly intended, remove `REVIEW` from the auto-eligibility DAG path (it is a human step) rather than shipping a gate that can never fire, and drop the misleading impossible-map test. + +### WR-02: `eligible()` downstream branch gates only on `!= DONE` (not on `IN_FLIGHT`), and propose in-flight is invisible — a latent re-enqueue vector for the exact class this layer guards + +**File:** `src/phaze/enums/stage.py:186-193`, `src/phaze/services/stage_status.py:158-167` + +**Issue:** The enrich branch correctly excludes both `DONE` and `IN_FLIGHT` (`not in (DONE, IN_FLIGHT)`), but the generic downstream branch (`TRACKLIST`/`PROPOSE`/`REVIEW`) only checks `status_map.get(stage) != DONE`. Combined with `inflight_clause` returning a constant `false()` for propose (its ledger key is a batch set-hash, scoped out per OQ1/Pitfall 5), a propose batch that is genuinely mid-flight derives `NOT_STARTED` (no proposal row yet, `inflight=false`), so `eligible(status_map, PROPOSE)` returns `True` while the stage is already running. That is precisely the "re-queue never-should-be-requeued work" shape behind the 2026-06-18 44.5K over-enqueue incident. It is documented as deferred and the deterministic-key/ledger dedup at enqueue time is the real backstop, but the eligibility layer itself offers no guard and the asymmetry with the enrich branch is silent. + +**Fix:** Make the guard uniform and defensive: exclude `IN_FLIGHT` in the downstream branch too — `return upstream_done and status_map.get(stage, Status.NOT_STARTED) not in (Status.DONE, Status.IN_FLIGHT)`. Separately, add an explicit note (or a follow-up ticket reference in the docstring) that propose in-flight is not representable until OQ1 cutover, so a future reader does not assume `eligible(PROPOSE)` is in-flight-safe. + +### WR-03: The fingerprint "done" allowlist `_DONE_FP` is hardcoded twice — two sources of truth the anti-drift phase is meant to eliminate + +**File:** `src/phaze/enums/stage.py:56` (frozenset) and `src/phaze/services/stage_status.py:86` (tuple) + +**Issue:** `_DONE_FP = {"success", "completed"}` is defined independently in both modules. `services/stage_status.py` already imports from `phaze.enums.stage` (`Stage`, `Status`), so it could import the single source but instead re-spells the literal. The entire premise of this phase is "the two halves can NEVER drift." A hand-copied allowlist is a silent drift seam: editing one (e.g. adding a third success alias) without the other breaks equivalence, and because the DERIV-04 test only asserts on the currently-enumerated statuses, a drift on a new alias would not necessarily be caught. + +**Fix:** Export the canonical allowlist from the DB-free module and import it in the SQL twin, e.g. in `enums/stage.py` expose `DONE_FINGERPRINT_STATUSES: tuple[str, ...] = ("success", "completed")` and in `stage_status.py` `from phaze.enums.stage import DONE_FINGERPRINT_STATUSES as _DONE_FP`. `.in_(tuple)` renders the same `= ANY (ARRAY[...])` and the frozenset-vs-tuple distinction is irrelevant for membership. + +## Info + +### IN-01: Four identical presence-status wrappers add no value + +**File:** `src/phaze/enums/stage.py:119-132` + +**Issue:** `_tracklist_status`, `_propose_status`, `_review_status`, and `_apply_status` all have identical signatures and bodies (`return _presence_status(present=row_present, failed=failed, inflight=inflight)`). `resolve_status` already dispatches all four to the same code path via the shared `row_present`/`failed` locals, so the four wrappers are dead duplication. + +**Fix:** Delete the four wrappers and call `_presence_status(present=row_present, failed=failed, inflight=inflight)` directly in `resolve_status` for the downstream branch (the stage identity is already known from the dispatch). If they are kept as intentional seams for future per-stage divergence, add a one-line comment saying so. + +### IN-02: Python `_presence_status` accepts a `failed` input for tracklist that the SQL twin hardcodes to `false()` — an uncovered twin-divergence seam + +**File:** `src/phaze/enums/stage.py:119-120`, `src/phaze/services/stage_status.py:137-138` + +**Issue:** For `TRACKLIST`, `failed_clause` returns a constant `false()` (no failure marker), but the Python `resolve_status(TRACKLIST, ...)` still honors a `failed` scalar. A caller that passes `{"failed": True}` for tracklist gets `Status.FAILED` from Python while the SQL twin can only ever yield `not_started`/`done`. The equivalence harness never exercises this (its tracklist reader hardcodes `failed=False`), so the divergence is undetected. Low risk today (no tracklist failure source exists), but it is a latent way for the two halves to disagree. + +**Fix:** Either drop the `failed` parameter from the tracklist path (ignore it, matching the SQL `false()`), or add an equivalence cell that would fail if a tracklist `failed` input were ever honored. A short comment on `_tracklist_status` noting "tracklist has no failure marker; `failed` is always False by contract" would also suffice. + +--- + +## Structural Findings (fallow) + +No structural pre-pass (``) was provided for this review. + +--- + +_Reviewed: 2026-07-08T00:00:00Z_ +_Reviewer: Claude (gsd-code-reviewer)_ +_Depth: standard_ From cdbd7b45ef2d8b7968b1f73fa270baa57ac97026 Mon Sep 17 00:00:00 2001 From: Robert Wlodarczyk Date: Wed, 8 Jul 2026 10:29:49 -0700 Subject: [PATCH 23/27] docs(phase-78): complete phase execution --- .planning/REQUIREMENTS.md | 48 ++++---- .planning/ROADMAP.md | 4 +- .planning/STATE.md | 25 ++-- .../78-VERIFICATION.md | 113 ++++++++++++++++++ 4 files changed, 152 insertions(+), 38 deletions(-) create mode 100644 .planning/phases/78-derivation-layer-eligibility-anti-drift-test-harness/78-VERIFICATION.md diff --git a/.planning/REQUIREMENTS.md b/.planning/REQUIREMENTS.md index 3a8d777c..0b769421 100644 --- a/.planning/REQUIREMENTS.md +++ b/.planning/REQUIREMENTS.md @@ -15,24 +15,24 @@ ### Derived Status Layer (DERIV) -- [ ] **DERIV-01**: A single predicate module is the one source of truth for every stage's `done` and `failed` predicate, expressed as reusable `ColumnElement[bool]` builders that compose into both SQL `.where(...)` and a Python per-row resolver — no stage predicate is written twice. -- [ ] **DERIV-02**: A pure function `stage_status(file, stage) -> {not_started | in_flight | done | failed}` returns the derived status for any file/stage, with precedence `in_flight ≻ done ≻ failed ≻ not_started`. -- [ ] **DERIV-03**: `done` is derived from the stage's output row using the *correct* completion predicate per stage: `metadata` row present (and not failure-only);

(2) `src/phaze/services/stage_status.py` — the SQLAlchemy `ColumnElement[bool]` twin: per-stage `done_clause`/`failed_clause`, `stage_status_case` CASE ladder, `inflight_clause` deriving in-flight from `scheduling_ledger` (D-01 authoritative, never `saq_jobs`), and `saq_detail` reading `saq_jobs` only as a `begin_nested()` SAVEPOINT-isolated corroborating detail that degrades safe; the D-01 written decision record lives in the module docstring (INFLIGHT-03/SC#5). 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/`.

Module top imports only `enum` and `typing` (`Mapping` under `TYPE_CHECKING`). Subprocess banned-import guard present at `tests/shared/test_stage_resolver.py:128` (`test_stage_module_stays_db_free`) — runs `import phaze.enums.stage` in a fresh subprocess and asserts `phaze.models`/`phaze.database`/`sqlalchemy` are absent from `sys.modules` (mirrors `tests/shared/core/test_task_split.py`). CLOSED. +- **T-78-02** — `resolve_status`/`eligible` (`src/phaze/enums/stage.py:135,167`) and their `_*_status` twins perform no I/O, no DB access, no writes, no string interpolation into any sink; they read plain scalars and return an enum.

CLOSED. +- **T-78-03** — All `done_clause`/`failed_clause`/`inflight_clause` predicates built via the SQLAlchemy expression API (`exists`, `select`, `.in_`, `func.concat`, `cast`, bound comparisons). The only raw `text()` is `_SAQ_DETAIL_SQL` (`src/phaze/services/stage_status.py:195`): a static literal with the status allowlist `('queued','active')` and NO f-string/`.format`/`%`/`+` interpolation of any operand.

CLOSED. +- **T-78-04** — `saq_detail` (`src/phaze/services/stage_status.py:198`) wraps its read in `async with session.begin_nested():` and has `except Exception:` that logs and returns the zeroed safe default `{queued:0, active:0}` with no re-raise. `inflight_clause` reads `SchedulingLedger`, never `saq_jobs`, for the boolean. Proven by `test_inflight_savepoint_degrade` (`tests/integration/test_stage_status_equivalence.py:431`) — drops `saq_jobs` mid-test, asserts safe default with no raise and `in_flight` still `True` from the ledger. CLOSED. +- **T-78-05** — `stage_status.py` issues SELECT-only against `saq_jobs`. `git log main..HEAD --name-only` shows zero alembic files touched in phase 78 (only the 4 impl/test files + eligibility DAG test changed). Migration 032's `saq_jobs` mentions are docstring/comment banners (negative "must never reference" assertions), not DDL. CLOSED. +- **T-78-06** — D-01 decision record present verbatim in the `stage_status.py` module docstring (`src/phaze/services/stage_status.py:33-55`): `scheduling_ledger` authoritative, `saq_jobs` corroborating-only, durability rationale (guards the 44.5K over-enqueue class), union/ledger-alone alternatives rejected. `inflight_clause` (line 150) implements ledger-row-exists via `exists(select(SchedulingLedger.key).where(...))`.
