Project Status

Last updated: 2026-04-04 (session 9). Individual story/defect/decision details now in stories/, defects/, decisions/ directories with corresponding index files.

Current Mission

D-040: Pure PipeWire filter-chain pipeline (CamillaDSP abandoned).

BM-2 benchmark showed PipeWire's built-in convolver is 3-5.6x more CPU-efficient than CamillaDSP on Pi 4B ARM (1.70% vs 5.23% at comparable buffer sizes). First successful PW-native DJ session (GM-12): 40+ minutes, zero xruns, 58% idle, 71C.

US-072 (NixOS Build) reactivated — 20 tasks filed, IMPLEMENT phase. Hardware validation complete on test Pi (192.168.178.35): PREEMPT_RT 6.12.62, VC4 hardware GPU, greetd + labwc + wayvnc, PipeWire + WirePlumber running, zero kernel WARNINGs. Production Pi at venue (unreachable).

US-079 IMPLEMENT Pre-convolver capture point Owner re-validation
US-080 IMPLEMENT Multi-point spectrum analyzer Owner re-validation
US-081 IMPLEMENT Peak+RMS meters with clip indicator Owner re-validation
US-082 IMPLEMENT Audio file playback in signal-gen Owner re-validation
US-083 draft Integration smoke tests Depends US-075 (now COMPLETE)
US-110 IMPLEMENT 0/17 Web UI passkey authentication Architect decomposed 17 tasks
US-111 IMPLEMENT 8/13 Local-demo PW graph topology redesign AC #1,2,3,5,7,10,11 done. #4,6 dropped. #8 manual verify. #9 under investigation (T-111-10).
US-113 IN PROGRESS (PR #22) First-boot active config + FoH passthrough PR #22: first-boot default venue loading (foh-passthrough.yml, GM auto-load, D-063 gate closed). Prior 5 phases committed. 34/34 mock E2E pass. Real-stack E2E still required for full acceptance (L-QE-002). F-271 tracks D-031 protection WAVs for ch 1-4.
US-114 TEST (Pi validated) Minimal kernel config for Pi 4B ~100 overrides committed + session 9 fixes (7976ee0, c791ada, 4c17ebb: SND_SOC/DRM_VC4 deps, initrd strip, NVMe disable). Kernel boots on test Pi with all required hardware. Remaining: build time/size docs (AC #6-7), upgrade procedure (AC #9).
US-115 IMPLEMENT (Phase 0 done) 8-channel filter-chain convolver (D-063) Phase 0 complete: 8ch configs, dirac.wav, gain nodes, routing. Critical path — blocks US-113 E2E.
US-116 ready Per-channel time delay measurement + compensation Depends US-115, US-113. 8 AC, 8 tasks. AE-consulted detection improvements.
US-117 draft Tier 1 image size: firmware/locale/git/registry trim ~1.1 GiB savings, zero functional impact. Depends US-072.
US-118 draft Tier 2 image size: Reaper closure optimization ~800 MiB savings. Reaper pulls VLC (1.4 GiB closure). Owner option decision needed. Depends US-072.
US-119 IMPLEMENT (partial) Tier 3 image size: Mesa without LLVM, PipeWire without bluez libcamera disable committed (1f3e865). Mesa V3D-only + PW no-bluez done earlier. ~500-800 MiB savings.
US-120 IMPLEMENT (complete) Real-time transfer function measurement All 7 tasks done (T-120-01 through T-120-07). Dual-FFT engine, delay finder, WS endpoint, design/verify mode, TF view, 11 Playwright + 19 integration tests. Awaiting Rule 13 review.
US-121 draft Real-time multichannel delay measurement Theory docs committed.
US-122 draft Real-time phase correction analysis Theory docs committed. Minimum-phase optimal for PA transient fidelity.
US-123 IMPLEMENT (done) GM deterministic boot state Implemented (6ef8f93): F-249 fix (quantum on startup), NixOS default standby, venue persistence, enhanced get_state RPC. 277 tests pass.
US-124 draft First-boot UX Filed (b391c98). Depends US-113.
US-125 IMPLEMENT (in progress) Explicit mode arming Worker-4 verifying existing behavior, may need minimal changes.
US-112 REVIEW (Rule 13 PASSED) PipeWire convolver hot-reload patch Rule 13 passed retroactively — all 5 advisors approved. 2 AD findings need fix: AD-R13-003 (atomic write in deploy_filters), AD-R13-004 (double-Reload leak). NixOS build needs patch regen for PW 1.6.2 (US-128).
US-126 IMPLEMENT (Rule 13 conditional) Persistent audio gate banner QE CONDITIONAL — needs _gate_section() unit test, mock gate key, banner integration test. Architect/UX/AD/AE approved.
US-127 draft (deferred) Runtime coefficient switching (D-053) Filed (1b9b7b9). Deferred until US-112 complete. If US-112 succeeds, destroy-and-recreate approach unnecessary.
US-128 draft Upgrade PipeWire to 1.6.2 nixpkgs already ships 1.6.2. Regenerate US-112 patch for new API. Investigate F-020 RT self-promotion. ~2.25 worker days.
US-131 REVIEW (PR #13) Parallel local-demo instances Instance ID isolation (0-9), port offset scheme (base + id*100), JSON manifest, PID-scoped cleanup. All T0+T1+T2+E2E pass.

Key Decisions

See decisions/ directory and decisions-index.md for all 63 decisions (D-001 through D-063). Most significant recent decisions:

  • D-040 (2026-03-16): Abandon CamillaDSP — pure PipeWire filter-chain pipeline
  • D-043 (2026-03-20): WirePlumber retained for device management, linking disabled
  • D-045 (2026-03-24): Project rename to mugge
  • D-058 (2026-03-28): GM supervises services — target arch (static units interim)
  • D-060 (2026-03-29): Local CA for TLS — replaces D-032 self-signed (unblocks US-110 passkeys)
  • D-061 (2026-03-30): GM manages PW/WP lifecycle — amends D-058 (PW/WP move from systemd to GM-managed)
  • D-062 (2026-03-30): First-boot / active config — symlink-based coefficient management, FoH passthrough baseline, mute-default safety (amends D-010, D-051, D-053)
  • D-063 (2026-03-30): 8ch filter-chain convolver + universal audio gate — owner directive: 8ch passthrough, mandatory gate, cosine ramp-up (amends D-062)

Accomplishments

  1. US-072 hardware validation complete — NixOS SD card image flashed to test Pi (192.168.178.35). 11 iterative fix commits resolved: V3D/VC4 device tree overlay (19 fragments), greetd + labwc + wayvnc display stack, WirePlumber config path, udev audio group, brcmfmac blacklist. Result: PREEMPT_RT 6.12.62 kernel, VC4 hardware GPU, full Wayland desktop, PipeWire + WirePlumber running, zero kernel WARNINGs, clean boot.
  2. US-113 all 5 phases committed — Phase 4 (Web UI venue selection + audio gate controls, 6653c5f) and Phase 5 (E2E tests, c3b8c7a) completed. QE approved 34/34 E2E. Story ready for owner acceptance.
  3. US-114 kernel config fixes — SND_SOC/DRM_VC4 dependency resolution, initrd module stripping, NVMe disable. Kernel validated on test Pi hardware.
  4. S8-dup incident documented — CLAUDE.md updated with session 8 team duplication incident (ninth occurrence).
  5. Gate 2 PASSED — Full audio workstation stack running on test Pi. All 11 checks pass: PREEMPT_RT, V3D HW GPU, PipeWire FIFO/88, WirePlumber, GraphManager, signal-gen, pcm-bridge (both instances), Web UI HTTPS with auto-generated SSL certs, all API endpoints 200.
  6. US-119 libcamera disable committed (1f3e865).
  7. Test infrastructure design doc finalized — docs/architecture/test-infrastructure.md, architect + QE approved.
  8. US-098 P1/P2 verified — 41/41 pass.
  9. Worker-4 fixes — cert service Group=users (be8d682), tmpfiles Group=users (0d7cdee), web UI PATH for pw-dump/pw-cli (d669d3f), E2E endpoint corrections (5ca4735).
  10. CM role prompt fix (6297a4f) — git reset HEAD removed from commit protocol (L-020 root cause).
  11. Nix store cleanup — 45.6 GB freed on builder.
  12. Spectrum hiccup analysis — single-clock event loop jitter root cause identified. Owner rejected decimation/batching fix. Approach TBD.
  13. Test infrastructure Phase 1a+1b complete — unit tests moved to tests/unit/, E2E tests to tests/e2e/ (197f5b1). Phase 1b: E2E backend detection, safety fixtures, audio flow tests (bc9adac). Playwright crash fix (e8d722e).
  14. E2E baseline established — 60 pass, 4 fail (F-249 GM quantum), 12 skip, 1 xfail. US-090/092-097 re-verification unblocked.
  15. Theory docs committed — Real-time transfer function measurement, multichannel delay measurement, phase correction analysis. AE reviewed. 6 commits.
  16. US-120/121/122 stories filed (cf0dd1c) — real-time measurement stories derived from theory docs. Pre-convolver references removed per owner directive (68c9654).
  17. F-249 filed and RESOLVED — GM quantum not changing on mode switch. Fixed by US-123 (6ef8f93). 277 tests pass.
  18. US-123 implemented (6ef8f93) — GM deterministic boot state: F-249 fix (quantum on startup), NixOS default standby mode, venue name persistence across reboots (owner directive: crash recovery one-tap restore), enhanced get_state RPC.
  19. 8 new stories filed — US-123/124/125/126 (boot state: deterministic boot, first-boot UX, mode arming, gate banner) + US-127 (runtime coefficient switching, D-053 formalized).
  20. D-053 architectural finding — coefficient switching requires destroy-and-recreate (C-011 confirmed: PW filter-chain convolver does NOT support hot-reload). Watchdog does NOT auto-unlatch after node recreation. Owner elevated D-053 as critical.

Test Pi Validation Results

All components verified on 192.168.178.35:

  1. US-113 Phase 3 complete — D-063 audio gate integrated into GraphManager. Gate starts closed (all Mult=0.0). open_gate RPC applies venue gains with cosine ramp-up. Watchdog mute now also closes the gate for consistency.
  2. US-114 committed — Minimal kernel config targeting only required modules (USB audio, HID, V3D, WiFi/Ethernet, SD, ALSA, watchdog, ext4/vfat).
  3. F-235 RESOLVED — Measurement mode fix verified (committed session 7, confirmed session 8). 36/36 tests pass, E2E pw-record capture working.
  4. python3 fix — local-demo scripts now use python3 instead of python.
  5. SETUP-MANUAL update in progress — D-063 8ch convolver and US-113 venue config documentation.

Commits (5 pushed)

SHA Description
8f42b8c US-115 Phase 0: 8ch convolver (configs, dirac.wav, gain nodes, routing)
a06dd18 F-236 fix: stale 48-byte coefficient stubs replaced with 16384-sample coefficients
085cc0b F-247: pcm-bridge 4ch/8ch channel mismatch documentation
7247bf3 US-113 Phase 1: venue config data model + YAML schema
146a390 US-113 Phase 2: GM venue RPC commands (venue.rs, serde_yaml, tests)

Accomplishments

  1. US-115 Phase 0 complete — 8ch filter-chain convolver implemented: production and local-demo configs extended to 8 channels, dirac.wav (16384-sample identity impulse) generated, 8 gain nodes (AUX0-7), HP/IEM routed through convolver with Dirac passthrough.
  2. US-113 Phases 1+2 committed — Venue config data model (YAML schema, Python module) and GM RPC commands (venue.rs, serde_yaml dependency, full test coverage).
  3. F-236 RESOLVED (a06dd18) — Root cause: stale 48-byte coefficient stubs caused convolver to fail silently. 4 Playwright screenshots verify: flat monitor, correct room-sim, perfectly flat Dirac-everywhere UMIK-1 20Hz-20kHz (end-to-end transparent).
  4. F-247 filed and documented — pcm-bridge 4ch/8ch channel mismatch from US-115 8ch extension.
  5. 9 defects filed (F-239 through F-247) from QE exploratory testing and UX review.
  6. 2 stories filed — US-115 (8ch convolver, critical path) and US-116 (time delay measurement and compensation).
  7. 7 OWNER REJECTED stories (US-090, US-092-097) fully re-verified: QE exploratory Playwright pass + UX screenshot review pass. Ready for owner re-acceptance.
  8. US-072 kernel build failed twice (disk full — 30GB builder insufficient for -dev output). US-114 (minimal kernel config) is next priority for reducing build size.

Session ended

VM bricked by unauthorized nix garbage collection (L-043). Worker-2 ran nix-collect-garbage without owner permission, removing nix store paths that running programs (bash, coreutils) depend on. VM completely unresponsive — no SSH, no shell. Owner will restore from snapshot. All 5 commits safely pushed to remote. Home directory intact.

Priorities for next session

  1. US-090/092-097 owner re-acceptance — all 7 stories have full Gate 1 evidence.
  2. US-115 remaining phases — Phase 0 done, integration testing needed.
  3. US-113 completion — Phases 1+2 committed, UI and E2E integration remain.
  4. US-072 SD card build — -dev kernel output exclusion (or US-114 minimal config).
  5. F-235 (HIGH) — measurement mode broken in local-demo, blocks US-097/US-098.
  6. F-244 (HIGH) — DELETE confirmation dialogs across config tab.

Accomplishments

  1. F-223 RESOLVED — auth middleware now opt-in via PI4AUDIO_AUTH_ENABLED=1 (adb93d9). Unblocks 7 OWNER REJECTED stories (US-090, US-092-097) for E2E re-verification.
  2. 9 defects resolved — F-223, F-225, F-226, F-228, F-230, F-232, F-233, F-238, plus multiple US-075 audit bugs.
  3. 35 new E2E production-replica tests committed (7b43222) for US-075 — mode switching, quantum, topology, meters.
  4. 5 new defects filed from owner morning testing — F-234 (4 missing DJ links), F-235 (measurement mode broken), F-236 (UMIK spectrum rolloff), F-237 (config activation UX), F-238 (sim gains trade-off).
  5. Monitoring → standby rename across 48 files (62105d8).
  6. Room-sim IR length corrected from 1024 to 16384 (0104d30).
  7. US-114 (minimal kernel config) filed as draft story.

Pending for Session 7

  1. E2E re-verification of US-090, US-092-097 — F-223 fixed, stories unblocked.
  2. F-235 (HIGH) — measurement mode broken in local-demo. Blocks US-098 P1/P2.
  3. F-234 — 4 missing DJ links. Investigation needed.
  4. F-236 — UMIK spectrum rolloff in test tab. Likely code duplication fix.
  5. US-072 — SD card build blocked on -dev kernel output exclusion.
  6. Status.md update — this file was stale (session 5).
