v2.12.0

Automated release: version and notes generated from pull requests merged since 2.11.0.

Added

• The remaining silent fallbacks, skips and warnings are recorded. Each still prints its stderr line and is now also a diagnostics entry, and contract --json lists every code with its bucket under json_output.diagnostic_codes: an odd-sized frame scaled to even before encoding (odd_dimensions_scaled_even), subtitle/data streams dropped on a retry with the first attempt's error (non_av_streams_dropped, beside dropped_non_av_streams), a --dry-run measurement skipped for an input an earlier stage would write (measurement_input_pending), ffmpeg -encoders/-bsfs that could not be read (ffmpeg_list_unreadable), an invalid or negative FFMPEG_SKILL_TIMEOUT (timeout_env_invalid), the libaom fallback for a missing SVT-AV1 (av1_encoder_libaom), a CRF capped at the encoder's maximum (crf_clamped), a timeline export that does not read back (timeline_parse_failed, with the reason), and every tool's former stderr-only warning: line (emoji fallbacks, silent, short or duplicate inputs, memory-heavy jobs, --strip-dovi without Dolby Vision, a numbering gap in sequence.py, render.py's frame-from-preset and default --normalize).
• font_used on the tools that draw text. overlay.py --text, graphics.py, caption.py (burn) and grid.py --label auto report {asked, file, family, how, substituted}; a family that is not installed and was drawn in another (fontconfig's answer, or Arial on Windows) is a font_substituted fallback.
• Counts for what was skipped. cropdetect.py windows / windows_failed; sync.py --fix-drift drift_skipped_reason (too_short / low_confidence); caption.py --ass caption.ass_shifted / ass_unshifted / ass_malformed; silence.py --filler filler.matched_untimed / matched_too_long.
• --codec av1/prores refusals say why. error.reason: encoder_missing (kind: missing_tool, as before) when the build's encoder list lacks the encoder; encoder_list_unreadable (kind: ffmpeg) when the list could not be read, instead of claiming the build lacks it. --hw's CPU note says the same.
• The MCP server answers a line that is not JSON with a JSON-RPC parse error (-32700, id: null) instead of dropping it.

Fixed

• A degraded or partial result is no longer reported as the asked-for one (nothing happens silently, part 2). Additive fields, plus the batch.py row error noted below:
  • render.py's verified is the conjunction of every stage's. A stage's own verification steps (beyond its intermediate's probe) are in the result's verification, tagged with stage, and its notes in notes, prefixed with its tool: an export that missed its platform loudness used to leave the render verified: true. An executed plan and a pack carry their children's the same way, and a --cache hit replays what the cached stage verified.
  • render.py's "check": {"content": true} without a platform runs check.py --content (it was skipped without a word; a plan's check step already ran it). A check not run under --dry-run is a check_dry_run skip, and check.py output that does not parse is a failure document (error.reason: check_output_unparsed) instead of a bare string.
  • render.py --cache says why each stage missed (cache.miss_reasons: not_cached, sidecar_missing, artifact_missing, sidecar_corrupt, artifact_truncated, no_output_path); a damaged entry is a cache_entry_damaged warning and an audit line in the cache directory; a failed store, an input that cannot be fingerprinted and an unreadable ffprobe banner are recorded.
  • export.py reports trimmed: {from, to} (and a note) when a platform maximum cut the clip. A loudness measurement that cannot be read is loudness.measured: false with a failing {step: loudness, ok: false, reason: not_measured} and a loudness_not_measured warning, instead of no loudness block and verified: true; after --normalize, the measurement from before the pass is no longer reused.
  • multicam.py's cuts name the camera actually rendered (camera 0 where the asked-for camera had not started), with a camera_not_started fallback naming the one asked for.
  • report.py lists each section it built as a verification step (loudness, compliance with passed, contact_sheet); one it could not build is ok: false with the child's reason and a report_section_missing warning, so the report is no longer verified: true with a section missing.
  • batch.py: a failed row's error is the failing step's own {step, tool, kind, message, code, reason, details, hint, exit_code} (it was absent, or a string such as "1" for a worker that exited); rows add verified and unverified (a completed but unverified step stays ok, as design-decisions decides), and the batch's verification has one item step per row. Ctrl-C reports a row for every input (interrupted: true, or skipped: "interrupted") and a total that counts them all. A cache hit is served only while its output's size and mtime are the ones the batch wrote (cache_miss on the row, a warning), so an entry written by 2.10.11 or earlier runs once more; a cache file that does not parse is a batch_cache_reset warning and an audit line. A recipe error that is the same for every item is refused before any item runs.
  • verify.py runs each step with --json and keeps the tool's own kind, reason, message and exit_code instead of the last stderr line or a fixed string; steps that do not apply are listed under each file's skipped with a reason.
  • export.py's and multicam.py's last stderr-only warning: lines are records too (colour_not_converted, output_audio_silent, loudness_outside_spec, sync_low_confidence), so no tool prints a warning that --json does not carry.
• Nothing happens silently, parts 2 and 3: degraded results, and the remaining fallbacks, skips and warnings (#350)
