# Phase 2 Plan 07: Pydantic Boundary-Log Schemas + Final Regression Gate — Summary
|
||||
|
||||
**One-liner:** Pydantic v2 boundary-log schemas (MavlinkGpsInputEmitted, ApiRequestCompleted, AnchorDecision) with frozen+extra=forbid contracts, 20 unit tests, and Phase 2 final regression gate: 236 tests pass, AC --check exit 0.
|
||||
|
||||
## What Was Built
|
||||
|
||||
### 1. log_schemas.py — 3 Pydantic v2 Boundary Models
|
||||
|
||||
**File:** `src/gps_denied/obs/log_schemas.py`
|
||||
|
||||
| Model | Fields | AC Link | Phase Wiring |
|
||||
|-------|--------|---------|--------------|
|
||||
| `MavlinkGpsInputEmitted` | lat_deg, lon_deg, alt_m, fix_type (ge=0 le=6), horiz_accuracy_m, source_label (Literal[3 values]), anchor_age_ms, cov_semi_major_m | AC-4.3, AC-1.4, AC-1.3 | Phase 5 / MAVOUT-01 |
|
||||
| `ApiRequestCompleted` | path, method (Literal[5 values]), status_code (ge=100 lt=600), duration_ms | AC-6.3 | Phase 6 REST middleware |
|
||||
| `AnchorDecision` | decision (accept/reject), reason (AnchorRejectReason Literal[5]), n_inliers, mre_px | VERIFY-02 | Phase 3 AnchorVerifier |
|
||||
|
||||
All models extend `_BoundaryLogRecord(BaseModel)` with `ConfigDict(extra="forbid", frozen=True)`:
|
||||
- `extra="forbid"`: producer-side field drift fails validation fast
|
||||
- `frozen=True`: records are immutable facts, not state
|
||||
|
||||
Type aliases exported: `SourceLabel`, `AnchorRejectReason` for producer code reuse.
|
||||
|
||||
### 2. tests/test_log_schemas.py — 20 Unit Tests, 17 AC-Tagged
|
||||
|
||||
| Test Group | Count | AC Tags |
|
||||
|------------|-------|---------|
|
||||
| `MavlinkGpsInputEmitted` round-trip + source_label 3 parametrize + rejects_unknown + fix_type 3 parametrize + extra_rejected + frozen | 10 | AC-4.3, AC-1.4 |
|
||||
| `ApiRequestCompleted` round-trip + unknown_method + status_bounds (2 assertions) | 3 | AC-6.3 |
|
||||
| `AnchorDecision` accept round-trip + 5 vocab parametrize + rejects_unknown_reason | 7 | AC-2.1b |
|
||||
|
||||
Module-level: `pytestmark = [pytest.mark.unit]`
|
||||
Per-test: `@pytest.mark.ac("AC-N.n")` on relevant tests.
|
||||
All 20 tests pass in 0.04 seconds (no I/O, pure Pydantic validation).
|
||||
|
||||
### 3. AC-TRACEABILITY.md Delta
|
||||
|
||||
| AC | Before (tests) | After (tests) | Status |
|
||||
|----|---------------|---------------|--------|
|
||||
| AC-1.4 | 2 | 7 | OK |
|
||||
| AC-4.3 | 20 | 26 | OK |
|
||||
| AC-2.1b | 0 | 6 | DEFERRED (pending-phase-4)* |
|
||||
| AC-6.3 | 6 | 7 | OK |
|
||||
| **ACs covered total** | **14** | **15** | — |
|
||||
|
||||
*AC-2.1b: schema contract tests added, but full AnchorVerifier integration requirement remains deferred to Phase 4.
|
||||
|
||||
### 4. End-to-End Frame-ID + Boundary-Record Smoke
|
||||
|
||||
`structlog.contextvars.merge_contextvars` (first processor in the configured chain) injects
|
||||
bound contextvars into every log record before the renderer fires. Verified directly:
|
||||
|
||||
```
|
||||
merge_contextvars propagation OK: {'event': 'test', 'correlation_id': 999, 'source_label': 'satellite_anchored', 'fix_type': 3}
|
||||
E2E spine + boundary-record smoke OK: {'event': 'mavlink_emit_gps_input', 'correlation_id': 999, 'source_label': 'satellite_anchored', 'fix_type': 3}
|
||||
```
|
||||
|
||||
Note: `structlog.testing.capture_logs()` intentionally replaces the full processor chain
|
||||
with a minimal capture, so `merge_contextvars` does not run inside `capture_logs()` blocks.
|
||||
This is expected structlog behavior. The plan's Task 4 inline script was adapted to verify
|
||||
`merge_contextvars` directly rather than through `capture_logs()`.
|
||||
|
||||
## Phase 2 Definition of Done — verified by Plan 02-07
|
||||
|
||||
- [x] All 7 PLAN.md files have SUMMARY.md siblings (this one being the last)
|
||||
- [x] pytest tests/ -q --ignore=tests/e2e passes at >= 216 (+ test_log_schemas.py count): **236 passed, 8 skipped**
|
||||
- [x] pytest -m unit / -m integration / -m blackbox each pass with zero failures (210 / 69 / 12)
|
||||
- [x] scripts/gen_ac_traceability.py --check exit 0
|
||||
- [x] git diff --exit-code .planning/AC-TRACEABILITY.md exit 0 (matrix committed clean)
|
||||
- [x] from gps_denied.obs.logging_config import configure_logging works
|
||||
- [x] from gps_denied.obs.log_schemas import MavlinkGpsInputEmitted, ApiRequestCompleted, AnchorDecision works
|
||||
- [x] correlation_id=frame_id propagates from orchestrator binding via merge_contextvars to hot-path log calls
|
||||
- [x] git diff --name-only tests/ shows only pytestmark + @pytest.mark.ac additions + new test_log_schemas.py (no logic edits)
|
||||
- [ ] ROADMAP.md Phase 2 row updated to "Plans Complete: 7/7" + "Status: Done" — **REQUESTED FOR HUMAN REVIEWER after merge**
|
||||
|
||||
## ROADMAP.md Update Request
|
||||
|
||||
After merging Phase 2 branch into main:
|
||||
1. In `ROADMAP.md`, update Phase 2 row: Plans Complete → `7/7`, Status → `Done`
|
||||
2. Optionally update the AC-2.1b row from "DEFERRED (pending-phase-4)" to add a note
|
||||
that schema contract tests now exist (6 nodeids), but the integration requirement
|
||||
is still pending Phase 4.
|
||||
|
||||
## Deviations from Plan
|
||||
|
||||
### Auto-adapted: capture_logs() assertion
|
||||
|
||||
**Found during:** Task 4 final regression gate
|
||||
**Issue:** The plan's Task 4 inline script asserts `e["correlation_id"] == 999` inside a
|
||||
`capture_logs()` block. `structlog.testing.capture_logs()` replaces all processors with a
|
||||
bare capture — `merge_contextvars` does NOT run, so context vars are absent from captured
|
||||
events. This is documented structlog behavior, not a bug.
|
||||
**Fix:** Verified `merge_contextvars` propagation directly by calling the processor
|
||||
function against an event dict with bound context. The production chain (Plan 02-06's
|
||||
`configure_logging`) wires `merge_contextvars` as the first processor — the invariant holds
|
||||
in production.
|
||||
**Impact:** No code change needed; assertion strategy adapted in smoke test verification.
|
||||

||||

|
||||

# Phase 2: Acceptance Criteria, Test Taxonomy, Observability Spine — Phase Summary
|
||||
|
||||
## Objective
|
||||
|
||||
Establish the verification infrastructure that Phase 3+ depends on:
|
||||
1. Formal 39-AC document with unambiguous pass/fail criteria
|
||||
2. pytest marker taxonomy (6 markers: unit/integration/blackbox/perf/hardware/ac)
|
||||
3. AC↔test traceability matrix + CI enforcement
|
||||
4. structlog hot-path spine (10 files, frame_id propagation)
|
||||
5. Pydantic v2 boundary-log schemas (3 models)
|
||||
|
||||

|
||||
|
||||
## Handoff to Phase 3
|
||||
|
||||
Phase 3 (Visual Odometry + AnchorVerifier) can begin with:
|
||||
- Known-good measurement floor: 236 tests, 8 skipped
|
||||
- AC-2.1b (anchor verification) has schema contract tests; Phase 3 adds integration
|
||||
- `AnchorDecision` schema ready for Phase 3 AnchorVerifier wiring
|
||||
- `merge_contextvars` propagation verified; orchestrator binds `frame_id` at frame entry
|
||||
|
||||
## ROADMAP.md Update (Human Action Required)
|
||||
|
||||
After merging Phase 2 branch:
|
||||
- Update Phase 2 row: `Plans Complete: 7/7`, `Status: Done`
