enricobuehler	705a8baddf	feat(core,host,client): PyroWave datagram-aligned packets + partial-frame delivery (Phase 4, §4.4) ... PyroWave AUs now packetize on the negotiated shard payload, so a lost datagram costs a few wavelet blocks of localized blur rather than a whole frame — and the client can render an aged-out lossy frame instead of freezing until the next one. Host (opt-in, PyroWave only): - The encoder packetizes at the shard payload behind a 4-byte window prefix (used-len u16 + kind u16). Whole packets pack into WIN_PACKED windows; a packet too large for one shard (PyroWave 32x32 blocks are atomic and can exceed a shard) rides a WIN_FRAG_FIRST/CONT/LAST chain. `set_wire_chunking()` joins the Encoder trait (forwarded through TrackedEncoder — the silent-no-op trap); EncodedFrame.chunk_aligned marks the AU. - virtual_stream tags the AU with USER_FLAG_CHUNK_ALIGNED and re-applies chunking after every encoder (re)build, the adaptive-bitrate rebuild included. Core: - USER_FLAG_CHUNK_ALIGNED (0x40) wire bit. Reassembler opt-in (set_deliver_partial): a chunk-aligned frame that ages out with holes is handed over as Frame{complete:false} — received shards at their exact offsets, missing ranges zero-filled — instead of being dropped. Partials age out on a tight 30ms fuse (PARTIAL_WINDOW_NS) instead of the 120ms loss window: each frame is independently decodable, so an ancient partial has no value in a live stream. Newest-wins. A partial still counts as dropped for loss reporting. Client (PyroWave decode): - The session opts in when codec == PyroWave. The decoder walks the AU window-by-window, skipping zero (missing) windows and reassembling FRAG chains, then decodes whatever survived. A newest-decoded-index guard drops partials the pump has already moved past (no time-travel present). Also fixes a redundant-closure clippy nit in the PyroWave planar-present path. Validated on an RTX 5070 Ti under 2% netem loss with FEC pinned off: 60fps sustained entirely via partials, e2e 43ms p50 (146ms before the fuse) vs 23ms lossless, no keyframe-recovery chatter. Tests green: core 149, host 310 + the GPU-gated encoder smoke (framed-window walk + FRAG reassembly + upstream round-trip), client 26; clippy clean on the pyrowave feature combos.

enricobuehler	e55ff1bb28	feat(recovery): clean mid-stream loss recovery — freeze-until-reanchor + AMD LTR-RFI ... Removes the "gray frames with motion" artifact on Vulkan-Video clients and lets AMD/NVENC hosts re-anchor after loss WITHOUT a 20-40x IDR spike. Client (pf-client-core): after a reference loss the hardware decoder conceals the missing-reference deltas (on RADV, a gray plate with new motion painted over) and returns Ok. The pump now freezes on the last good picture until a clean re-anchor instead of showing the concealment — lifting on a real IDR, an intra-refresh recovery mark (2nd wave boundary), or an LTR-RFI recovery anchor (1st). The frame_index gap is the early, precise loss signal and drives an RFI request. Host recovery signals (inert unless the backend supports them): - USER_FLAG_RECOVERY_POINT — intra-refresh wave boundary (NVENC constrained GDR). - USER_FLAG_RECOVERY_ANCHOR — AMD LTR reference-frame-invalidation recovery frame. AMD LTR-RFI (encode/windows/amf.rs) — the AMD twin of NVENC RFI. AMF's AVC/HEVC API has no constrained-intra property (intra-refresh cannot heal; PSNR-proven), so the only clean-recovery lever is user LTR: mark frames as long-term references, and on loss force the next frame to re-reference the newest known-good one — a clean P-frame, not an IDR. Two rotating LTR slots, ~0.5s mark cadence, on by default for AVC/HEVC (PUNKTFUNK_NO_AMF_LTR disables). invalidate_ref_frames picks the newest LTR before the loss; a range older than the live slots falls back to a keyframe. Protocol (punktfunk-core): RfiRequest control message + NativeClient::request_rfi(). Host: RfiRequest dispatch -> invalidate_ref_frames (IDR fallback); an RFI success anchors the keyframe cooldown so the client's frames_dropped echo of the same loss is coalesced away rather than emitting a redundant IDR. Spike: synthetic NV12 GPU source for headless AMF encoder testing. Validated: core rfi_request_roundtrip; pf-client-core 31 unit tests (incl. an_rfi_anchor_lifts_immediately); punktfunk-host builds + 271 tests on Linux; punktfunk-host builds clean on Windows; real AMD iGPU spike (invalidate at frame 90 forced re-reference to LTR frame 60 — 180 frames, keyframes=1, no recovery IDR).

enricobuehler	8cceb93541	rename: lumen → punktfunk, everywhere ... Full project rename, decided 2026-06-10: - Crates/binaries: punktfunk-core / punktfunk-host / punktfunk-client-rs. - C ABI: punktfunk_* symbols, Punktfunk* types, include/punktfunk_core.h, PUNKTFUNK_FEATURE_QUIC guard (header regenerated; cbindgen renames updated, incl. PUNKTFUNK_BTN_*/PUNKTFUNK_AXIS_* wire constants). - Protocol: punktfunk/1 — control-plane magic LMN1 → PKF1, nonce salt lmn1 → pkf1. WIRE BREAK: clients must be rebuilt from this revision. - Env knobs: PUNKTFUNK_VIDEO_SOURCE / PUNKTFUNK_COMPOSITOR / PUNKTFUNK_ZEROCOPY / …. - Host config dir: ~/.config/punktfunk (the box's dir was migrated in place — the persistent identity is unchanged, pinned fingerprints stay valid). - Swift package: PunktfunkKit + PunktfunkCore.xcframework + PunktfunkConnection (Sources/PunktfunkClient app + tests renamed with it); build-xcframework.sh updated. - scripts/: 60-punktfunk.rules, punktfunk-host.service; OpenAPI doc regenerated. Also: scripts/headless/run-headless-kde.sh — full headless Plasma bringup. Root cause of "desktop but no apps/settings" over the stream: plasmashell launched without XDG_MENU_PREFIX=plasma-, so the launcher resolved a nonexistent applications.menu and rendered an empty menu. The script sets the complete KDE session env (menu prefix, KDE_FULL_SESSION, session version) and rebuilds ksycoca before starting plasmashell. Gate: 97/97 tests, clippy -D warnings (both feature sets), fmt, C-ABI harness PASS, zero lumen references left outside .git.
