enricobuehler	cdb43f00fe	style: rustfmt the freeze-until-reanchor client wiring ... cargo fmt --all --check flagged the reanchor gate wiring (decode.rs / session.rs / abi.rs / reanchor.rs): wrapped signatures + comparisons, and two multi-line comments that followed a trailing-comment line were restructured to their own lines so rustfmt keeps them at normal indentation instead of deep-aligning them.

enricobuehler	8a18e130a2	feat(client): freeze-until-reanchor loss recovery on Android + Apple via shared core gate ... After unrecoverable loss the host keeps sending delta frames that reference a picture the client never received; hardware decoders conceal these as gray/ garbage with a success status. Linux already withheld them and held the last good frame until a proven clean re-anchor — this brings that behavior to the Android and Apple clients. Extract the Linux pump's freeze state machine into a shared `ReanchorGate` in punktfunk-core (reanchor.rs, 18 tests) exposed over the C ABI (ABI v6, additive — no wire change) for the Swift clients. Migrate the Linux/Deck pump (pf-client-core) onto it as the parity proof (no-op refactor). Then wire: - Android (decode.rs, both sync + async loops): arm on the frame-index gap, a pts-keyed flag map carries the wire flags to the output-buffer release, fold the gate per drained output, gate.poll replaces the dropped-climb block. - Apple Stage2Pipeline (default): arm on a gap (new noteFrameIndexGap), withhold at the ring-submit seam (CAMetalLayer holds its last drawable), poll framesDropped, fold VT decode errors through the no-output streak. - Apple StreamPump (stage-1): fold at enqueue, withhold via kCMSampleAttachmentKey_DoNotDisplay so the layer keeps decoding (reference chain intact) but holds the last displayed frame. - Apple VideoDecoder: thread the AU's wire flags to the async decode callback via a retained FrameContext refcon (replaces the receivedNs bit-pattern scalar). Lifts only on a proven re-anchor (IDR / RFI anchor / 2nd recovery mark) with a 500 ms backstop so a lost re-anchor can never freeze forever. Apple: swift build clean, 123/123 tests pass (incl. VideoToolboxRoundTripTests). On-glass loss-injection validation still owed. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-13 01:22:09 +02:00
