[AZ-404] [AZ-389] [AZ-559] E2E replay test (Derkachi 60s) + AZ-389 cleanup

Batch 63 of /autodev replay slice. Adds the AZ-404 E2E test harness against the Derkachi fixture and resolves the AZ-389 dependency phantom (closing AZ-559 Won't Fix). E2E test (AZ-404) - tests/e2e/replay/_tlog_synth.py: deterministic CSV->tlog generator (the original Derkachi tlog is not in repo; data_imu.csv is its export, so we round-trip the CSV through pymavlink). Verified: SCALED_IMU2 + ATTITUDE + GPS_RAW_INT + HEARTBEAT round-trip cleanly through mavutil.mavlink_connection. - tests/e2e/replay/_helpers.py: parse_jsonl, l2_horizontal_m (haversine), match_percentage, CapturingMavlinkTransport (ready for AZ-558 unblock), GroundTruthRow + load_ground_truth_csv. - tests/e2e/replay/conftest.py: derkachi_replay_inputs (session scope), replay_runner (subprocess fixture per AZ-402 CLI), operator_pre_flight_setup placeholder. - tests/e2e/replay/test_derkachi_1min.py: 9 tests covering AC-1..AC-8 with AC-7 skip-gate self-check + AC-4a mode-agnosticism AST scan (passes unconditionally, confirms ADR-011 holding). - tests/e2e/replay/test_helpers.py: 14 unit tests covering AC-9 helper L2 correctness + match_percentage + parse_jsonl + CapturingMavlinkTransport (all unconditional). - tests/e2e/replay/README.md: AC matrix, fixture state, runtime budget, failure cookbook (AC-10). AC matrix - AC-1, AC-2, AC-5, AC-6 implemented and Tier-1 gated on RUN_REPLAY_E2E=1. - AC-3 (<=100m for 80%) xfail until real Topotek KHP20S30 calibration ships (camera_info.md states intrinsics are unknown). - AC-4a (mode-agnosticism AST scan) PASSES unconditionally. - AC-4b (encoder byte-equality) skip until AZ-558 routes C8 bytes through MavlinkTransport. - AC-7 (skip-gate self-check) PASSES unconditionally. - AC-8 (operator workflow rehearsal) skip until D-PROJ-2 mock-suite-sat-service implements tile-fetch + index-build endpoints. - AC-9 (helper L2 correctness) 14 PASSES unconditionally. AZ-389 housekeeping - AZ-559 closed Won't Fix: investigation against c6_tile_cache/_types.py confirmed TileSource.ONBOARD_INGEST + TileMetadata.quality_metadata + write_tile's FreshnessRejectionError already cover the mid-flight ingest semantic. The "missing API" was a spec-vs-impl naming mismatch. - AZ-389 spec rewritten to consume the existing write_tile API + catch FreshnessRejectionError per AC-NEW-3 opportunistic emission. - _dependencies_table.md reverted: AZ-389 deps -> AZ-303 (was AZ-559 in the previous commit on this branch); total 150 / 497 pts. Tests - Full regression: 2099 passed (+14 new e2e/replay), 94 skipped (incl. 8 e2e/replay heavy-tier + documented blocker skips), 3 perf-microbench flakes deselected (test_cli_cold_start_under_2s, test_cold_start_under_500ms_p99, test_nfr_perf_sign_microbench; all pass in isolation - pre-existing under-load flakes on dev macOS). Reviews - _docs/03_implementation/reviews/batch_63_review.md: code review PASS_WITH_WARNINGS (3 documented spec-gap deferrals: AC-3, AC-4b, AC-8). - _docs/03_implementation/cumulative_review_batches_61-63_cycle1_report.md: cumulative review PASS_WITH_WARNINGS. Action items: prioritise AZ-558 (closes AZ-401 AC-9 + AZ-404 AC-4b); consider 2pt hygiene PBI for Protocol-completeness AST scan to catch the AZ-389 / AZ-559 phantom-API pattern at task-prep time. Architecture invariants observably holding - ADR-011 (replay-as-configuration): AC-4a's AST scan over src/gps_denied_onboard/components/**/*.py finds zero violations - components branch on neither config.mode nor any synonym. - Single composition root (replay protocol Invariant 11): AZ-402 CLI dispatches to runtime_root.main(config); does not call compose_root directly.

 # C5 Orthorectifier → C6 mid-flight tile gen sub-path

 **Task**: AZ-389_c5_orthorectifier_c6
-**Name**: C5 internal orthorectifier — produces mid-flight tile candidates for C6
-**Description**: Implement the orthorectifier sub-path inside C5: when a frame has converged in the iSAM2 graph (≥1 satellite anchor + visual consistency), apply the camera intrinsics + extrinsics + the C5-known pose to orthorectify the nav-camera frame into a tile-aligned image patch; emit a `MidFlightTileCandidate(tile_id, pixels, quality_metadata, source_pose)` to C6 (via the storage interface AZ-303 `tile_store.put_mid_flight_candidate(...)`). Quality metadata: `inlier_count`, `cov_norm`, `pose_age_ms`. The orthorectifier is C5-internal (per epic spec § Scope: "orthorectifier (lives within C5 as an internal subcomponent)"); it consumes the converged pose + nav frame from a per-frame buffer; it emits at most ONE candidate per frame (gated by quality thresholds: `cov_norm < threshold` AND `inlier_count > floor`). Triggered after a successful `current_estimate()` call when quality conditions hold.

+- `inlier_count` is NOT a field on `TileQualityMetadata`; the orthorectifier uses it for the gate but persists `mre_px` (mean reprojection error) which serves the same downstream consumer (C6 voting status updater).

 ## Risks & Mitigation

 - **Risk: Orthorectification produces low-quality tiles under degenerate pose** — quality gates filter; if still problematic, AZ-308 cache-eviction policy filters at storage time.
- **Risk: AZ-303 `put_mid_flight_candidate` API not yet stable** — this task ships against the documented API surface.
+- **Risk: `cov_norm` (Frobenius norm of 6x6) vs `covariance_2x2` (horizontal sub-block) mismatch confuses readers** — *Mitigation*: docstring on the orthorectifier explicitly distinguishes the two uses; the gate operates on the 6x6 norm; the sub-block is only persisted for downstream voting-status readers.

 ## Runtime Completeness

- **Named capability**: orthorectifier → mid-flight tile candidate emission.
- **Production code**: real orthorectification kernel (NumPy or OpenCV), real quality gates, real tile_store.put_mid_flight_candidate call.
- **Unacceptable substitutes**: emitting raw nav-frame pixels (not orthorectified); skipping the quality gates (AC-NEW-3 corruption).
+- **Named capability**: orthorectifier → mid-flight tile candidate emission via `TileStore.write_tile`.

+- **Unacceptable substitutes**: emitting raw nav-frame pixels (not orthorectified); skipping the quality gates (AC-NEW-3 corruption); inventing a parallel `put_mid_flight_candidate` path when `write_tile` already exists.

+# Cumulative Code Review — Batches 61-63 (Cycle 1)
+
+**Date**: 2026-05-14
+**Range**:
+- batch 61 (AZ-401 + AZ-400 absorbed — `compose_root` replay branch + `MavlinkTransport` Protocol seam)
+- batch 62 (AZ-402 — `gps-denied-replay` console-script + shared `runtime_root.main(config)`)
+- batch 63 (AZ-404 — E2E replay fixture test + AZ-389 housekeeping; AZ-559 closed Won't Fix)
+
+**Compared against**: previous cumulative review batches 58-60.
+**Verdict**: **PASS_WITH_WARNINGS**
+
+## Scope
+
+The 61-63 trio closes the **replay subsystem** end-to-end:
+
+- **Batch 61** wired the `compose_root` replay branch + retrofitted the missing `MavlinkTransport` Protocol seam from AZ-400 (originally specced under AZ-400 but missing when AZ-401 came up; absorbed to unblock the slice).
+- **Batch 62** added the `gps-denied-replay` console-script CLI. The shared airborne `main()` was refactored additively to accept a pre-built `Config`, letting the CLI build → mutate → inject without violating ADR-011's "single composition root" constraint.
+- **Batch 63** added the E2E test harness against the Derkachi 60 s clip — full AC matrix wired (some ACs deferred behind documented blockers); plus an AZ-389 spec-vs-impl reconciliation that proved the AZ-559 follow-up was unnecessary (the existing `TileStore.write_tile` + `TileSource.ONBOARD_INGEST` + `FreshnessRejectionError` cover the mid-flight ingest path).
+
+The replay slice is now functionally complete on the airborne side: AZ-405 (coordinator) → AZ-401 (compose_root branch) → AZ-402 (CLI) → AZ-404 (E2E test).
+
+## Carry-over status from cumulative review 58-60
+
+| Prior finding | Status | Notes |
+|---------------|--------|-------|
+| 58-60 F1 (Medium) — Replay contract `ReplayInputAdapter.__init__` missing `fdr_client` | RESOLVED earlier | Contract updated in batch 60; no further work. |
+| 58-60 F2 (Low) — Two parallel tlog message-type pre-validators | OPEN — carry forward | Untouched. The AZ-404 e2e fixture's `_tlog_synth.py` produces a tlog that satisfies BOTH validators by construction, so the duplication is observably harmless. |
+| 58-60 F3 (Low) — Test-only injection kwargs on `ReplayInputAdapter.__init__` | OPEN — pattern formalised | Batches 61 + 62 + 63 all adopted the same "single optional kwarg defaulting to None, lazy-resolved at call time" pattern (`replay_components_factory` in AZ-401, `shared_main` in AZ-402, `replay_runner` closure in AZ-404). The pattern is now used by **four** coordinators. Recommend factoring to a shared `_TestInjections` helper after a fifth use case (still under threshold). |
+| 58-60 F4 (Low) — Two `cv2.projectPoints` calls per Marginals frame | OPEN — carry forward | No code in batches 61-63 touched C4. |
+| 58-60 F5 (Low) — AZ-361 AC-11 informational latency comparison | OPEN — carry forward | Informational metric per spec; no action. |
+| 55-57 F1 (Low) — engine-output-probe FP32 vs FP16 dtype divergence | OPEN — carry forward | No code in batches 61-63 touched C2 / C3 TRT path. |
+| 55-57 F2 (Low) — XFeat underscore-prefixed helper imports | OPEN — carry forward | No movement. |
+| 55-57 F3 (Low) — AZ-347 latency benchmark not asserted | OPEN — carry forward | Informational. |
+| 52-54 F2 (Low) — c1_vio test fakes not yet shared | OPEN — carry forward | Subsumed under AZ-528 (filed earlier). |

+
+### Finding Details
+
+#### F1: AZ-558 blocks two ACs (High / Spec-Gap)
+
+- **Locations**:
+  - `tests/unit/test_az401_compose_root_replay.py:526` (`test_ac9_noop_transport_bytes_written` — `pytest.skip`)
+  - `tests/e2e/replay/test_derkachi_1min.py:269-278` (`test_ac4_encoder_byte_equality` — `pytest.skip`)
+- **Description**: The C8 outbound adapters (`PymavlinkArdupilotAdapter`, `Msp2InavAdapter`) call `connection.mav.gps_input_send(...)` directly — bytes never flow through the `MavlinkTransport` seam. AZ-558 was filed in batch 61 to close this gap. Until it lands:
+  - AZ-401 AC-9 (`NoopMavlinkTransport.bytes_written() > 0` after replay-mode runtime drive) is unsatisfiable.
+  - AZ-404 AC-4b (encoder byte-equality between live and replay via `CapturingMavlinkTransport`) is unsatisfiable.
+- **Risk-shape note**: AZ-558's spec flags a known-unknown — pymavlink's signing handshake runs inside `mav.*_send`, not at `connection.write` level. A naive seam shape (`MavlinkTransport.write(bytes)`) would skip signing. This may push AZ-558's nominal 3pt → 5pt during implementation; track at task-prep time.
+- **Status**: explicit + tracked. The `CapturingMavlinkTransport` infrastructure is in place (with full unit coverage in `test_helpers.py`); when AZ-558 lands, both skips drop in a small follow-up.
+- **Suggestion**: prioritise AZ-558 in a near-future batch — it's the single dep that closes two open ACs.
+
+#### F2: AC-8 blocked on D-PROJ-2 mock (High / Spec-Gap)
+
+- **Location**: `tests/e2e/replay/test_derkachi_1min.py:357-371` (`test_ac8_operator_workflow` — `pytest.skip`).
+- **Description**: AZ-404's spec calls for the test to run the operator's full C10/C11/C12 pre-flight against a `mock-suite-sat-service` fixture before invoking the replay CLI (replay protocol Invariant 12 + epic AC-9). The current `tests/fixtures/mock-suite-sat-service/` is a bootstrap stub (`GET /healthz` only); the full D-PROJ-2 ingest contract isn't in the parent-suite design yet (`_docs/_process_leftovers/2026-05-09_satellite-provider-design-tasks.md`).
+- **Status**: explicit + tracked at parent-suite level. The `operator_pre_flight_setup` fixture in `conftest.py` yields a placeholder cache directory so the test body fails fast with a clear reason rather than a surprise import error.
+- **Suggestion**: when the parent-suite D-PROJ-2 design lands, file a separate task to implement the mock and unskip AC-8.
+
+#### F3: AC-3 `xfail` until real calibration (Medium / Spec-Gap)
+
+- **Location**: `tests/e2e/replay/test_derkachi_1min.py:113-148` (`test_ac3_within_100m_80pct_of_ticks` — `pytest.mark.xfail(strict=False)`).
+- **Description**: AC-3 is the epic's primary acceptance gate but `_docs/00_problem/input_data/flight_derkachi/camera_info.md` explicitly states the Topotek KHP20S30 intrinsics are unknown. The test is fully implemented, runs against the placeholder `tests/fixtures/calibration/adti26.json`, and reports a real percentage. With wrong intrinsics, the percentage will land near 0%; `xfail(strict=False)` lets a future correct calibration eventually pass without a fail-on-pass surprise.
+- **Status**: explicit + tracked at fixture level.
+- **Suggestion**: when real KHP20S30 calibration ships, drop the marker (or flip to `strict=True` for one CI run before removing).
+
+#### F4: Three replay-track tasks with upstream-dep gaps (Medium / Process)
+
+- **Pattern**: AZ-401 (missing AZ-400 transport seam), AZ-389 (phantom `put_mid_flight_candidate` API — resolved by re-reading AZ-303's actual surface), AZ-404 (missing tlog fixture, missing real calibration, missing D-PROJ-2 mock, blocker on AZ-558). Three back-to-back replay-track follow-ons each surfaced an upstream gap.
+- **Resolution**:
+  - AZ-401: absorbed AZ-400's residual scope into the same batch.
+  - AZ-389: investigation showed the gap was a spec-vs-impl naming mismatch — `TileSource.ONBOARD_INGEST` + `TileMetadata.quality_metadata` + `write_tile`'s built-in `FreshnessRejectionError` already cover the mid-flight ingest path. AZ-559 closed Won't Fix; AZ-389 spec rewritten to consume the existing API.
+  - AZ-404: gaps that CAN be filled in-batch (synthetic tlog, AC-4a AST scan, helper unit coverage) shipped; gaps that CAN'T (real calibration, AZ-558 routing, D-PROJ-2 mock) are explicit `skip` / `xfail` markers with documented reasons + tracker links.
+- **Why this is a finding**: the pattern shows that "shipped-tasks-vs-spec" can silently drift across feature boundaries. The mitigation is the **AC-4a mode-agnosticism AST scan** (now passing) — it gives the architecture a live structural-invariant check that fires regardless of `RUN_REPLAY_E2E`. A similar invariant for "every spec'd Protocol method is implemented" would catch future AZ-389-style phantoms; can be a future hygiene ticket.
+- **Suggestion**: file a 2pt hygiene PBI to add an AST-level "Protocol completeness" check to the unit suite — for each `runtime_checkable` Protocol, verify each in-repo concrete class implements every method named in the Protocol's source. This catches the AZ-389 phantom-API pattern at task-prep time instead of batch-implementation time.
+
+#### F5: Optional-kwarg test-injection pattern (Low / Style — carry-forward escalation)
+
+- **Locations**:
+  - `src/gps_denied_onboard/runtime_root/__init__.py:_compose(...)` accepts a `pre_constructed` kwarg (AZ-401).
+  - `src/gps_denied_onboard/cli/replay.py:main(argv, *, shared_main=None)` (AZ-402).
+  - `src/gps_denied_onboard/replay_input/tlog_video_adapter.py:ReplayInputAdapter.__init__(..., tlog_source_factory=None, video_frames_factory=None, video_timestamps_factory=None)` (AZ-405).
+  - `src/gps_denied_onboard/components/c8_fc_adapter/tlog_replay_adapter.py:TlogReplayFcAdapter.__init__(..., source_factory=None)` (AZ-399).
+- **Description**: Four production constructors / functions now accept a single optional kwarg that defaults to `None` and resolves to the production dependency lazily (or `None`-as-passthrough). Tests inject fakes through the kwarg without monkeypatching. Cumulative review 58-60 noted this at three sites; this window adds a fourth.
+- **Suggestion**: still under the "factor when fifth case appears" threshold. Track for batch 64+.
+
+#### F6: Synthetic tlog generation (Low / Maintainability)
+
+- **Location**: `tests/e2e/replay/_tlog_synth.py`.
+- **Description**: The Derkachi fixture ships `data_imu.csv` (already exported from a tlog) but not the source tlog itself. `_tlog_synth.py` reproduces a `pymavlink.dialects.v20.ardupilotmega` tlog from the CSV — `SCALED_IMU2` + `ATTITUDE` + `GPS_RAW_INT` + `HEARTBEAT`. Deterministic, atomic-write via `.tmp` + fsync + rename, ~1 s for 60 s of data. The conftest synthesizes once per session.
+- **Why this is not a Critical**: the alternative (checking the source tlog into the fixture) would add a new ~5 MB binary to `_docs/00_problem/`; the synth approach keeps the fixture content surface narrow + reproducible.
+- **Suggestion**: keep. Document in `tests/e2e/replay/README.md` (already done).
+
+## Architecture Observations (this window)
+
+- **ADR-011 holding**: AC-4a's mode-agnosticism AST scan is passing across all `src/gps_denied_onboard/components/**/*.py` files — confirms batches 60 / 61 / 62 / 63 honoured the structural guarantee. If a future batch introduces a `if config.mode` branch in any component, the e2e suite catches it on the next CI run regardless of `RUN_REPLAY_E2E`.
+- **Single composition root holding**: the AZ-402 CLI does NOT call `compose_root` directly — it builds a `Config`, calls `runtime_root.main(config)`, and `compose_root` runs inside there. Replay protocol Invariant 11 (CLI MUST NOT compose) verified at the type level.
+- **Layer direction holding**: `cli/replay.py` is Layer 5 per `module-layout.md`; imports flow Layer-5 → Layer-4 (`replay_input.errors`) → Layer-1 (`config`, `logging`). No backward edges.
+
+## Verdict Reasoning
+
+Two High spec-gap findings + one Medium spec-gap finding + one Medium process finding + two Low style/maintainability findings. All have explicit tracking via Jira / contract / spec-doc / code-comment links. No Critical, no Architecture violations. The architecture invariants the replay slice was supposed to deliver (ADR-011, single composition root, layer direction, mode-agnosticism) are all observably holding — verified by AC-4a's live structural test.
+
+Verdict: **PASS_WITH_WARNINGS**.
+
+## Action Items (recommended)
+
+1. **AZ-558**: prioritise — closes AZ-401 AC-9 + AZ-404 AC-4b in a single follow-up. Acknowledge the signing-handshake risk (3pt → likely 5pt).
+2. **Hygiene PBI candidate** (process F4): "Protocol completeness AST scan" — a 2pt unit-suite addition that compares each `runtime_checkable` Protocol to each in-repo class claimed to implement it, surfacing phantom-API specs at task-prep time. Catches the AZ-389 / AZ-559 pattern preemptively.
+3. **D-PROJ-2 mock follow-up** (F2): when the parent-suite design lands, file a task to implement the full ingest contract in `tests/fixtures/mock-suite-sat-service/` so AZ-404 AC-8 can unskip.
+4. **Real calibration delivery** (F3): when the Topotek KHP20S30 intrinsics + body-to-camera SE3 are obtained, drop the `xfail` on AZ-404 AC-3.

+### Finding Details
+
+**F1: AC-4b blocked on AZ-558** (High / Spec-Gap)
+
+- Location: `tests/e2e/replay/test_derkachi_1min.py:269-278` (`test_ac4_encoder_byte_equality` decorated with `@pytest.mark.skip`).
+- Description: AZ-404's spec asserts that the C8 outbound encoder produces byte-identical wire output between live and replay (replay protocol Invariant 5). The test would capture both modes' bytes via `CapturingMavlinkTransport` and diff. **Blocker**: per the batch 61 review F1 + AZ-558 spec, the C8 adapters (`PymavlinkArdupilotAdapter`, `Msp2InavAdapter`) currently call `connection.mav.gps_input_send(...)` directly — the bytes never flow through the `MavlinkTransport` seam, so substituting `CapturingMavlinkTransport` captures nothing. The test infrastructure (`CapturingMavlinkTransport` in `_helpers.py`, with full unit coverage in `test_helpers.py`) is in place; the test body is a placeholder marked skip with the AZ-558 reference. When AZ-558 lands, drop the `@pytest.mark.skip`, write the body (5–10 LOC), and AZ-401 AC-9 + AZ-404 AC-4b unskip together.
+- Suggestion: keep the skip; the alternative (silently drop the AC) is worse.
+- Task: AZ-404 (test scaffolding); blocker on AZ-558 (the routing retrofit).
+
+**F2: AC-8 (operator workflow) blocked on D-PROJ-2 mock** (High / Spec-Gap)
+
+- Location: `tests/e2e/replay/test_derkachi_1min.py:357-371` (`test_ac8_operator_workflow` decorated with `@pytest.mark.skip`).
+- Description: AZ-404's spec calls for the test to run the operator's full C10/C11/C12 pre-flight flow against a `mock-suite-sat-service` fixture before invoking the replay CLI (replay protocol Invariant 12 + epic AC-9). **Blocker**: `tests/fixtures/mock-suite-sat-service/main.py` is a bootstrap stub (only `GET /healthz`) per its README; the full D-PROJ-2 ingest contract (tile-fetch + index-build endpoints) hasn't been implemented yet. The `operator_pre_flight_setup` fixture in `conftest.py` yields a placeholder cache directory so the test body fails fast with a documented reason rather than a surprise import error.
+- Suggestion: keep the skip. File a follow-up to implement D-PROJ-2 in the mock service when the parent-suite design lands (`_docs/_process_leftovers/2026-05-09_satellite-provider-design-tasks.md` is the parent-suite design tracker).
+- Task: AZ-404 (test scaffolding); blocker on parent-suite D-PROJ-2 design.
+
+**F3: AC-3 `xfail` until real calibration** (Medium / Spec-Gap)
+
+- Location: `tests/e2e/replay/test_derkachi_1min.py:113-148` (`test_ac3_within_100m_80pct_of_ticks` decorated with `@pytest.mark.xfail`).
+- Description: AC-3 (≤100m horizontal accuracy for ≥80% of ticks) is the epic's primary acceptance gate. The test is fully implemented but **xfail'd** because the Derkachi camera (Topotek KHP20S30) does not have a real calibration JSON in repo — `_docs/00_problem/input_data/flight_derkachi/camera_info.md` explicitly states "Camera intrinsics, lens distortion, raw camera resolution, and exact camera-to-body calibration are still unknown". The placeholder `tests/fixtures/calibration/adti26.json` is wired in `conftest.py` so the test runs to completion and reports a real percentage; with wrong intrinsics it will land near 0%. Marking `xfail` (with `strict=False`) preserves the test infrastructure without polluting the green-build signal until the real calibration lands.
+- Suggestion: keep `xfail` with the current reason text; when a real KHP20S30 calibration ships, drop the marker. Strict=False so a future "good calibration" doesn't immediately fail-on-pass; flip to strict=True after one passing CI run on Tier-1.
+- Task: AZ-404 (test scaffolding); blocker on the calibration data deliverable.
+
+**F4: tlog synthesis from CSV** (Low / Maintainability)
+
+- Location: `tests/e2e/replay/_tlog_synth.py`.
+- Description: The Derkachi fixture ships `data_imu.csv` (already exported from a tlog) but not the source tlog itself. The CLI consumes a tlog path (per AZ-402's argparse contract). `_tlog_synth.py` reproduces a `pymavlink.dialects.v20.ardupilotmega` tlog from the CSV — `SCALED_IMU2` + `ATTITUDE` + `GPS_RAW_INT` + `HEARTBEAT` per the `_REQUIRED_MESSAGE_GROUPS` contract. The synthesizer is deterministic, single-pass, fast (~1 s for 60 s of data), and the conftest atomic-writes the output through a `.tmp` rename + fsync. Verified end-to-end: `mavutil.mavlink_connection(synth_path)` round-trips all four message types.
+- Suggestion: keep. Best alternative would be checking the source tlog into the fixture (≈ 5 MB), but that introduces a new binary in `_docs/00_problem/`; the synth approach keeps the fixture content surface narrow.
+- Task: AZ-404.
+
+**F5: `replay_runner` invocation-counter via closure** (Low / Style)
+
+- Location: `tests/e2e/replay/conftest.py:155-198`.
+- Description: The `replay_runner` fixture closes over a single-key `dict` (`{"n": 0}`) to assign each invocation a fresh output path. This avoids `nonlocal` / class-based state and matches the "function with mutable closure cell" pattern already used in batch 60's `replay_input` test factories. AC-5's two-runs-diff assertion proves the fixture produces independent output files per call.
+- Suggestion: keep.
+- Task: AZ-404.
+
+## Phase Summary
+
+### Phase 1 — Context Loading
+
+Inputs read:
+
+- `_docs/02_tasks/todo/AZ-404_replay_e2e_fixture.md` (full spec).
+- `_docs/02_document/contracts/replay/replay_protocol.md` v2.0.0 (Invariants 1, 5, 7, 10, 12 — verified by AC-4a / AC-4b / AC-5 / AC-8).
+- `_docs/02_document/architecture.md` (ADR-011 — replay-as-configuration; AC-4 enforces the structural guarantee).
+- `_docs/00_problem/input_data/flight_derkachi/README.md` + `camera_info.md` (fixture state).
+- `src/gps_denied_onboard/components/c8_fc_adapter/replay_sink.py` (`_to_jsonable` for AC-2 schema verification).
+- `src/gps_denied_onboard/components/c8_fc_adapter/tlog_replay_adapter.py` (`_REQUIRED_MESSAGE_GROUPS` for the synth contract).
+- `src/gps_denied_onboard/components/c6_tile_cache/_types.py` (for AZ-389 spec rewrite to use existing `TileSource.ONBOARD_INGEST`).
+
+### Phase 2 — Spec Compliance
+
+| AC | Verdict | Test | Notes |
+|----|---------|------|-------|
+| AC-1 | PASS (gated) | `test_ac1_exits_0_jsonl_count_match` | runs on Tier-1 with `RUN_REPLAY_E2E=1` |

+
+Three ACs are deferred behind documented blockers (F1/F2/F3); the rest are either unconditional-and-passing or implemented-and-running-on-Tier-1.
+
+### Phase 3 — Code Quality
+
+- **SOLID**: Each helper has one job:
+  - `_tlog_synth.synthesize_tlog` — CSV → tlog only.
+  - `_helpers.parse_jsonl` / `l2_horizontal_m` / `match_percentage` — pure functions.
+  - `_helpers.CapturingMavlinkTransport` — Protocol-conformant byte recorder.
+  - `conftest.derkachi_replay_inputs` — fixture materialisation only.
+  - `conftest.replay_runner` — subprocess invocation only.
+  - `_ModeBranchScanner` (AST visitor) — single-purpose AST traversal.
+- **Error handling**: explicit. `parse_jsonl` raises `AssertionError` with line number + decode-error message on bad input; `synthesize_tlog` writes via `.tmp` + atomic rename + fsync; the `replay_runner` fixture skips (NOT errors) when the console-script is missing from PATH.
+- **Naming**: clear (`l2_horizontal_m`, `match_percentage`, `CapturingMavlinkTransport`, `_ModeBranchScanner`).
+- **Complexity**: longest function is `synthesize_tlog` (~80 LOC, linear with one inner loop over CSV rows). No cyclomatic > 10.
+- **Test quality**: 24 collected; 16 pass on dev (helpers + AC-4a + AC-7), 8 skip (heavy-tier + 3 deferred ACs). Each test has explicit Arrange / Act / Assert sections (`# Arrange` etc.). Parametrised tests not used because each test exercises a distinct scenario.
+- **Dead code**: none.
+
+### Phase 4 — Security Quick-Scan
+
+- **No SQL / shell / `eval` / `exec` / `pickle`**: all surface is argparse + json + Path operations + pymavlink (a trusted dependency already pinned in the project).
+- **Subprocess invocation**: `replay_runner` runs `gps-denied-replay` with explicit argv (no shell expansion); the binary path is resolved via `shutil.which` then `Path(sys.executable).parent`, both of which are immune to PATH-based attacks at test time.
+- **No hardcoded secrets**: the e2e signing key is 32 zero-bytes (`b"\x00" * 32`); generated at fixture time; written to a tmp_path that pytest cleans up.
+- **Calibration JSON**: the fixture loads `adti26.json` (a placeholder), not operator-supplied data.
+
+### Phase 5 — Performance Scan
+
+- `_tlog_synth.synthesize_tlog`: ~1 s for the 60 s clip (verified during dev run).
+- `_helpers.match_percentage`: O(n log m) over n emissions × m ground-truth rows (binary search per emission); bounded by AC-1's expected line count (~600).
+- `_ModeBranchScanner`: O(N) over component .py files (~80 files in `src/gps_denied_onboard/components/`); ~0.2 s in practice.
+- The CLI subprocess fixture is the dominant cost on Tier-1 (≤ 30 s asap, 60 s realtime); within the AZ-404 NFR (≤ 6 min total).
+
+### Phase 6 — Cross-Task Consistency
+
+- AZ-389 housekeeping: closed AZ-559 (Won't Fix), reverted dep table, rewrote AZ-389 spec to consume the existing `TileStore.write_tile` + `TileSource.ONBOARD_INGEST` + `TileMetadata.quality_metadata` + `FreshnessRejectionError` semantic. Total task count restored to 150 / 497 pts.
+- AZ-558 still tracked as the unblocker for AC-4b (and AZ-401 AC-9). The `CapturingMavlinkTransport` ships in `_helpers.py` with full unit coverage so the AZ-558 batch only needs to flip the skip + write 5–10 LOC.
+- The mode-agnosticism AST scan (AC-4a) currently passes — verifies that batches 60 / 61 / 62 honoured ADR-011's structural guarantee. If a future component-side refactor introduces a `if config.mode` branch, the e2e suite catches it on the next CI run regardless of `RUN_REPLAY_E2E`.
+
+### Phase 7 — Architecture Compliance
+
+- **Layer direction**: `tests/e2e/replay/` is test code — no layer constraints. Imports flow Test → Layer-1 (`config`, `_types`) → Layer-4 (`replay_input`, `c8_fc_adapter`); no forbidden directions.
+- **Public API respect**: `_helpers.py` imports `MavlinkTransport` from `gps_denied_onboard.components.c8_fc_adapter.interface` (the public surface). `_tlog_synth.py` imports the standard `pymavlink.dialects.v20.ardupilotmega` module — same pattern as the production `tlog_replay_adapter.py`.
+- **No new cyclic deps**: the test package is leaf; nothing in `src/` imports from `tests/`.
+- **Mode-agnosticism (AC-4a)**: the test that verifies it passes — no batch 63 changes to `components/**/*.py` (we only added test files).
+
+## Verdict Reasoning
+
+Three High/Medium spec-gap findings, all with documented blockers and clean follow-up paths. Two Low style findings. No Critical. Comparable to batch 61's PASS_WITH_WARNINGS verdict — the deferrals are honest tracking of upstream-dep gaps rather than design defects.
+
+Verdict: **PASS_WITH_WARNINGS**.
+
+## Follow-up tracker
+
+- AZ-558: closes AC-4b + AZ-401 AC-9.
+- D-PROJ-2 mock-suite-sat-service implementation: closes AC-8.
+- Real Topotek KHP20S30 calibration data: closes AC-3.
