- Around line 188-191: Optimize the audio Time Remap path at `source_time(l)` so
preview and export do not invoke the production JavaScript expression evaluator
for every output sample. Use an audio-specific evaluation strategy that
preserves exact per-sample semantics for arbitrary expressions; do not
approximate with control-rate interpolation, and retain exact evaluation where
an optimization cannot be proven safe.

@h-a-n-a-s-h-i Could you review this when you have a chance? The latest commit, I reproduced all three before fixing them: valid low-frame-rate exports exceeded the mixer limit, a failed movie mix left a partial output, and an expression runtime limit silently fell back and retried per sample. Exports now mix bounded blocks; failed jobs remove only their owned output paths; audio expressions share a cumulative deadline/yield budget, with a shorter scrub deadline. The scrub test now drives the real Cmd-drag gesture and checks the drawn error toast, audio feed, current time, and recovery. Full For merge order, the small Windows helper fix #1889, font-test isolation #1890, and socket fix #1891 are separate PRs; their changes are included here so this branch's complete Windows CI passes. Merging those first would reduce this PR's diff. The Chinese fallback race fix #1907 is independent. Happy to adjust the split if a different review order is preferable. |

The two retained audio architecture concerns are addressed in
Full CI also reproduced two existing failures previously reported in other PRs. Those now have separate test-only fixes: #1915 removes wall-clock assumptions from Auto backend tests; #1916 serializes only the four Windows viewer screenshot harnesses after reproducing a d3d10warp.dll crash with three parallel screenshot tests. Ten backend-test repetitions, five screenshot-subset repetitions, two full viewer runs, and full CI passed afterward. No test was newly skipped and production graphics behavior is unchanged. Documentation updates are also pushed to #1889 and #1891. Suggested merge order: the small companion fixes #1889, #1890, #1891, #1915 and #1916 first, then this audio PR (their changes are included here as separate commits where applicable). The Chinese fallback fix #1907 remains independent. |

Native playback rerun on 6a9ebb5 passed: fresh process, same-session reopen, replay after stop, arithmetic expressions, looping, cancellation, work-limit reporting/recovery, and a second process. Audio remained active past 12 seconds and normal runs stopped at the intended 359/24-second endpoint. Manual cancellation stopped an expensive script in 25 ms; allowing it to continue produced the expected work-limit message in 658 ms. Verification used the native audio-device path/status/meters plus a visual screenshot, not a loopback recording or listening assessment. The new review findings are addressed: Unix staging files now request mode 0666 subject to umask, with a Unix-only regression comparing normal file creation; screenshot harness overlap is removed and post-release state assertions added. The Unix-only test cannot run on this Windows host. The general request to lock UI-only viewer tests does not apply to the installed lazy renderer; construction assertions and the explanation on #1916 document why those tests stay parallel. Pushed in 5adbd8f. Final combined Windows cargo xtask ci: 3,683 passed, 0 failed, 33 unchanged ignored; formatting, strict Clippy, audits, and 32-crate WASM checks passed. An additional 64-thread ui_viewer run passed all 66 tests. Companion PR files are byte-identical to those validated in the combined audio branch. |

Reproduced the restricted-file issue on Linux: the previous implementation exposed staging media with group/other read bits under umask 022. Staging files now start owner-only at creation. Existing Unix access-mode bits are captured and are intersected with any tighter destination mode observed before publication. New destinations retain ordinary umask-filtered creation modes, measured with a separate empty probe that never contains media. Failure to inspect the destination policy aborts publication. Added regression coverage for 0600/0640/0400 replacements, staging confidentiality, permissions changed or destinations removed during encoding, and permission-lookup failure/cleanup. The actual production out.rs and pending.rs modules were compiled into a small Linux test harness and executed in WSL on its Linux filesystem: all seven tests passed under each of umasks 022, 077 and 002, and Unix-target strict Clippy passed. This is focused Linux verification, not a full Linux application build. The socket recovery hardening from #1891 is also included in this branch as a separate companion commit. Pushed in 7b81eb7. The final combined Windows cargo xtask ci passed: 3,685 tests passed, 0 failed, 33 unchanged ignored; formatting, strict Clippy, audits and 32-crate WASM checks passed. The standalone socket PR file is byte-identical to the file validated in the combined audio branch. |

@coderabbitai full review The latest commit narrows this PR to audio Time Remap and its necessary evaluation/cancellation/error handling. Please review the current aggregate diff against the base branch. Export staging/file replacement was removed and preserved for separate follow-up, so the symlink and group/ACL findings against that implementation are no longer part of this diff. The existing direct-write/cleanup limitations are explicitly documented in the PR description. Companion socket/font/platform-test fixes remain in their own PRs. Validation: 118 focused tests, representative and 180-second workloads, and native playback/reopen/restart/cancel/recovery checks passed on the exact reduced source. Full CI with the separately tracked companion fixes temporarily overlaid passed (3,680 tests, zero failures); the overlay was removed before committing. Exact standalone Windows CI still encounters the baseline #1889 test-helper warning. The description distinguishes these results. |

Rebased onto main b55cb5b and pushed 2175376. The Unix fixture is now exactly upstream's version from #1855; #1889 is no longer a pending prerequisite. The final audio PR patch is unchanged by the rebase. Validation on the rebased branch, without companion fixes:
No unrelated fixes were added. A fresh CodeRabbit review has been requested because automatic review was paused. CodeRabbit's manual review request completed with 'No files to review' and its marker now lists 2175376 as last reviewed. It posted no new findings; this was not a new full analysis or a rerun of its previously timed-out Clippy tool. |
|
Thanks for tackling this. Per-sample remap with absolute page alignment is a good approach, and the block-boundary tests are convincing. A few things need to change before this can land:
|
Dependencies and merge order
Independent feature; proposed landing position 8, after the baseline validation fixes. Land before #1922 in the proposed sequence. Their integration must retain cancellation in the shared host job constructor, add cancel: None to the export-preflight job initializer, and preserve both export test groups. We will carry the saved, tested resolutions into #1922 after this lands.
Full nine-PR index, merge instructions, audited heads and validation evidence. The first five positions are independent, not a serial dependency chain. Combined CI evidence is not a claim of nine standalone full-suite passes.
Review status for e1a2625: all current actionable findings are addressed. CodeRabbit verified that failed scrub mixing clears queued audio and confirmed its old merge-risk text is stale and must not remain a blocker (correction). The combined CI and strict Clippy checks passed; CodeRabbit's separate Clippy execution remains timed out.
Time Remap changes picture source time, but the shared audio mixer previously used only stretch-adjusted layer time. A 15-second composition remapping source seconds 26–39 therefore played/exported audio from seconds 0–15.
Evaluate Time Remap per output audio sample, including holds, reverse source motion, jumps and nested compositions. Linear resampling changes pitch; pitch-preserving time stretching is outside this change.
Keep sample evaluation practical and bounded: exact scalar arithmetic expressions use a prepared evaluator; unsupported syntax uses the production JavaScript runtime. Source pages are bounded and reused. Shared work, instruction-yield and native time allowances include nested mixes and audio parameter expressions. Playback, scrubbing and export propagate cancellation/resource failures instead of accepting partial audio. Exports split large audio batches without changing sample alignment. The public mixer now returns Result and its callers are updated.
Oversized ordinary time-stretch reads are paged with interpolation lookahead, without weakening cumulative work/cancellation controls. Property-read pass exhaustion also marks the active audio control failed instead of silently falling back. Regression tests cover both reproduced review findings.
Scope
Validation
cargo xtask ciis blocked by the preexisting WindowsStillsdead-code test-helper warning (test(engine): guard the Unix-only importer fixture #1889). For integration validation only, the existing companion fixes from test(engine): guard the Unix-only importer fixture #1889/test(text): isolate metric-font fallback tests from host fonts #1890/fix(script): interrupt blocked socket writes on close #1891/test(render): make automatic backend checks independent of timing #1915/test(ui): serialize Windows viewer screenshot harnesses #1916 were temporarily applied: fullcargo xtask cipassed, 3680 tests passed, zero failed, 33 ignored; fmt, strict release Clippy, audits and the 32-crate WASM check passed. Those companion files were restored byte-for-byte before committing; they are not in this PR. Merge the companion PRs separately to make the Windows baseline gate green.Limitations
General JavaScript expressions can still be too expensive for real-time playback. Native deadlines are cooperative and cannot preempt blocking media providers/native callbacks; WebAssembly uses instruction/work allowances. Exceptionally costly legitimate projects can hit limits. Scrubbing uses a tighter allowance and reports failure rather than queueing partial audio.
