The on-wire shape is computed by an explicit `_to_jsonable` helper instead of `dataclasses.asdict` — `asdict` cannot meet AC-4 (numpy 6×6 → flat 36-float list, not a nested 2-D shape) or AC-5 (enum → name string, not value or repr) within the orjson default options. + +The AZ-390 `interface.py` previously carried a `ReplaySink` stub with a single-method `write(...)` shape that had drifted from the contract. `interface.py` now owns only `FcAdapter` + `GcsAdapter` per the corrected `module-layout.md` line; the canonical Protocol lives in `replay_sink.py` and is re-exported through `__init__.py`. The AZ-390 conformance test was widened to assert both `emit` + `close` and to reject partial implementations. + +`TlogReplayFcAdapter` (AZ-399) is the replay-mode `FcAdapter` strategy. Construction validates `BUILD_TLOG_REPLAY_ADAPTER` and the dialect (`ARDUPILOT_PLANE` or `INAV` only — `GCS_QGC` is rejected). `open(...)` runs a bounded pre-scan (`_PRESCAN_MAX_MESSAGES = 6000`) that asserts every required message group (RAW_IMU OR SCALED_IMU2; ATTITUDE; GPS_RAW_INT OR GPS2_RAW; HEARTBEAT) is represented, then starts a dedicated decode thread that streams the rest of the tlog through pymavlink's `recv_match(blocking=False)` — never materialising the file (R-DEMO-2). Frames are wrapped in `FcTelemetryFrame(received_at=msg._timestamp_ns + time_offset_ns, signed=False)` and dispatched via the existing AZ-391 `SubscriptionBus` so live and replay consumers see identical fan-out shape (Invariant 1). + +Outbound surface is hard-failed per Invariant 5 (`emit_external_position` and `emit_status_text` raise `FcEmitError("replay adapter does not emit to FC")`); `request_source_set_switch` raises `SourceSetSwitchNotSupportedError`. Pacing honours Invariant 6: `pace=REALTIME` calls `Clock.sleep_until_ns(received_at)` between frames, `pace=ASAP` skips the call. Non-monotonic timestamps inside the dispatched stream raise `FcOpenError` (mirrors the AZ-398 TlogDerivedClock policy). + +The decode-side path duplicates the AP mapping logic from `_inbound_mavlink.PymavlinkInboundDecoder` deliberately — replay differs in four observable ways (timestamp source, signed flag, non-monotonic policy, no STATUSTEXT spoof promotion) and a shared mapper would have to expose seams for all four.

Today the duplication is intentional — the replay path differs from live in three observable ways: (a) `received_at` is the tlog timestamp + `time_offset_ns` (not `Clock.monotonic_ns()`), (b) `signed=False` is hard-coded per the D-CROSS-CVE-1 risk, (c) non-monotonic timestamps raise `FcOpenError` instead of being dropped, and (d) STATUSTEXT spoof-promotion is intentionally absent because the replay channel carries the recorded stream verbatim.
