Under the Red storage tier, MP4 finalization (TS->MP4 remux) was being skipped, so tasks never reached Completed and the segment_completed event script — which uploads the file and deletes the local source to free space — never ran. The disk could never recover, deadlocking all recording and transcoding.
Two reversed checks caused this: (1) FfmpegService gated finalization on the legacy HasEnoughSpace MB threshold (effectively 4GB) instead of the tier system, and (2) the polling loop only resumed paused finalizations when NOT in the Red tier. Now finalization is gated solely on ShouldPauseActive (true Red only) and the polling loop always attempts to resume it every cycle, since finalization is the very mechanism that frees space. Once any segment finalizes, the upload+delete script runs and the disk recovers, letting the rest finish.

scripts/build-arm64-image.sh automates the full linux/arm64 image build on Docker Desktop (WSL2): register qemu-aarch64 binfmt with the F flag so emulation works inside build containers, pre-pull the dotnet base images with resumable retries, build with dotnet restore routed through the host proxy and apt via the in-Dockerfile mirror, then docker save + gzip into a loadable archive. .gitignore now excludes the *.tar/*.tar.gz build artifacts, the qemu-*-static emulator binary, and the stray root package-lock.json.

Alias the replay player's danmakuEvents to replayDanmakuEvents so it no longer shadows another binding in the session detail view.

Pin the WebApi to RuntimeIdentifier=linux-arm64 (framework-dependent) and rework the Dockerfile for ARM64: copy the full context up front, add QEMU emulation workarounds, and drop debug symbols / cap parallelism during publish.

Introduce a process-wide DatabaseCircuitBreaker that fails fast when Postgres is unavailable (e.g. disk full) instead of letting every request burn doomed EF Core retries. CircuitAwareExecutionStrategy derives from NpgsqlRetryingExecutionStrategy and records success/failure around the public Execute/ExecuteAsync seams; background workers skip work and back off while the circuit is open; the exception middleware maps an open circuit (and other DB outages) to 503. Adds /health (liveness) and /health/ready (readiness, reporting circuit state), plus unit tests for the open/half-open transitions and non-transient SQLSTATE detection.

Add a segment-level cleanup alongside the existing session-level one. DeleteMissingFileTasksAsync scans all non-active record tasks, keeps those whose video file no longer exists on disk, and deletes them individually via DeleteTasksAsync (which also drops any session left empty). Exposed as POST /record-tasks/delete-missing-files and a new "清理无文件分片" action in the record tasks view.

- CanStartNewRecording now purely based on Tier==Green (was HasEnoughSpace||Green)
- PollingBackgroundService now uses ShouldPauseActive instead of MB-based CheckShouldPause
- Both pause and start checks consolidated into single guardCheck call
- Old MB pause/resume thresholds still work as secondary safety via hasEnoughSpace

Add StorageGreenThresholdPercent (default 30%) and StorageRedThresholdPercent
(default 10%) to both SystemSettingsDto and the settings UI.
StorageGuardService now reads thresholds from settings instead of hardcoding.

DbContext is not thread-safe. Task.WhenAll caused concurrent access
within the same scoped DbContext, throwing 'A second operation was
started on this context instance' errors on slower machines.

VITE_API_BASE_URL may not be properly resolved during Docker build,
causing axios to construct malformed URLs.

Raspberry Pi PostgreSQL is I/O constrained. 60s timeout was too short
for concurrent writes during heavy recording sessions, causing timeout +
retry causing duplicate key violations.
- CommandTimeout: 60s -> 120s
- maxRetryCount: 5 -> 3
- maxRetryDelay: 10s -> 15s

PlatformHttpClientFactory was holding a direct ISystemSettingsService reference
(Scoped). When the danmaku connection's request scope ended, retry attempts failed
with ObjectDisposedException on LiveRecorderDbContext.
Changed to use IServiceScopeFactory to create a fresh scope on each CreateAsync call,
so the danmaku retry loop always gets a live DbContext.
