• What parameters and equations define ACES 2.0 chroma compression, gamut compression and the AP1 reach mode, and where do the docs and the reference code differ? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Corrected 2026-10-23 - see C3-B686-01; the original statements below are kept for history and are superseded where the correction says so. At aces-docs 7c34c210 and aces-core 069b0bc3, chroma-compression constants agree between docs and CTL (1.3, 0.69, 0.5, 2.4, 3.3 with log10(peak/100) scaling), but the gamut-compression docs describe a constant lower-hull gamma of 1.14 and an unscaled focusDistance while the CTL computes lower_hull_gamma = 1.14 + 0.07*log_peak and scales focus distance with log_peak; the gamma change dates from aces-core commit cd5017c5 (30 Aug 2024, CA-B095).

• In Trelby 2.4.16.2, which Fountain and FDX elements survive import and export, and which production reports does it generate? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Corrected 2026-10-23 - see C3-B686-02; the original statements below are kept for history and are superseded where the correction says so. Trelby's manual (86079b16) documents Fountain import losses (no emphasis markup, dual dialogue split into two dialogues, sections/synopses as notes, title pages and page breaks as action) and FDX import of text and script notes only (Final Draft 8 files, no formatting); its generateFDX writes element types and text without scene-number attributes. The manual's intro says 'three' import formats but lists six.
• Are GOV.UK line-heights all explicit pixel values, and are the USWDS type-scale numbers sourced? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem. C2-B99-J2-02 says GOV.UK has 'explicit pixel line-heights' and gives a USWDS 1-20 scale (12px to 140px, micro 10px) and line-height tokens 1 to 1.75, while its four cited URLs are three GOV.UK lines and one Carbon file. Conditions. Choosing type sizes and line-heights. Method. In the GOV.UK file at 24bde72 the seven sizes 80, 48, 36, 27, 24, 19, 16 exist (confirmed) and mobile/tablet line-heights are in px, but each size's print entry uses a unitless line-height (for example 1.1, 1.15, 1.05, 1.2), so 'explicit pixel line-heights' is true only for screen values. Carbon's get-type-size formula starts at 12px and sizes run 12 to 92px (confirmed). The USWDS figures have no cited source and I did not verify them. Failure modes. Applying pixel line-heights to print styles. Limitations. USWDS tokens unchecked. Version and date. govuk-frontend 24bde72, carbon 571cd54, fetched 2026-10-23.
• Are the USWDS grid and breakpoint claims in the GOV.UK/USWDS/Carbon comparison backed by a cited source? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem. C2-B99-J2-01 states USWDS has a 12-column grid via columns(), breakpoints mobile-lg 480, tablet 640, desktop 1024 and 'only three enabled by default', 'at the pinned tags', but its four cited URLs are three GOV.UK files and one Carbon file; no USWDS source is cited. Conditions. Laying out a page in USWDS style. Method. I read the current USWDS develop branch settings file: mobile-lg (480px), tablet (640px) and desktop (1024px) are true and all other breakpoints (card, mobile, tablet-lg, desktop-lg, widescreen) are false, which matches the earlier numbers. This is develop, not the unnamed pinned tag, so version drift is possible. The 12-column claim was not verified. GOV.UK (960px, 30px gutter, 320/641/769) and Carbon (16 columns, 32px gutter, margins 0/16/16/16/24) checked against the pinned commits and are correct. Failure modes. Citing uncited numbers as pinned-tag facts. Limitations. columns() grid not checked. Version and date. USWDS develop branch fetched 2026-10-23.
• Does the Smithsonian FAQ summarised in the earlier finding come from the cited URL, and does the FAQ say it gives no accuracy guarantee? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem. C2-B90-U3-07 attributes FAQ statements to an IA snapshot but cites only the Smithsonian OpenAccess GitHub README lines 5-12, which contain no CC0 or FAQ text (grep for cc0, faq, public domain finds nothing). Conditions. Using the Smithsonian CC0 designation as a rights signal. Method. I fetched the IA snapshot of si.edu/openaccess/faq (20250912113456). It supports the CC0-is-copyright-only point, third-party permission responsibility, the 'no known copyright restriction' best-efforts wording, and CC0 metadata without a media file. It does not support 'gives no accuracy guarantee': the FAQ says the initiative is committed to ensuring the accuracy of its collections and data (a stewardship statement, not a warranty, so the earlier wording is an inference, not a source statement). Failure modes. Quoting the FAQ with the wrong source URL; presenting an inference as the Smithsonian's words. Limitations. Terms of Use page, which the FAQ refers to for disclaimers, was not read. Ve...
• Is the APCA versus WCAG luminance difference really just the exponent, or does APCA add a near-black clamp, and has the WCAG threshold value changed? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem. C2-B90-U3-04 says APCA uses channel^2.4 with no linear segment while WCAG 2.2 uses the piecewise curve with a 0.04045 threshold. Conditions. Comparing contrast outputs from APCA and WCAG tools. Method. The APCA reference code at 6c5c066 computes Ys as three coefficients times (channel/255)^2.4 (confirmed). The APCA doc adds that the pre-processing stage includes a soft clamp at black, and that this clamp is why the piecewise segment is called redundant; the earlier finding states the redundancy without the reason, which could suggest near-black values are untreated. The WCAG 2.2 value is not covered by any cited URL; I fetched WCAG 2.2 and it confirms 0.04045 and notes it was 0.03928 before May 2021, so tools built on older text may differ slightly. Failure modes. Comparing APCA to old WCAG calculators near black without accounting for the clamp. Limitations. I did not read the clamp code. Version and date. apca-w3 6c5c066 and WCAG 2.2 TR page, fetched 2026-10-23.
• What conditions does the ICC attach to the sRGB v4 Preference profile beyond 'not changed', and how do they differ from the general library licence? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem. C2-B69-W1-04 summarises the sRGB v4 terms as use/copy/distribute provided the file is not changed. Conditions. Redistributing the profile in a tool, dataset or test suite. Method. The ICC page says permission is granted to anyone who acknowledges the file is provided 'AS IS' with no warranty, provided the file is unchanged including the copyright tag, and that ICC's name is not used in advertising or publicity without written permission. The display-class version is stated to have the same terms. The general library statement is different (it permits sale and embedding without restriction; altered versions must not be misrepresented). Failure modes. Treating the sRGB v4 terms as the permissive library licence, or re-saving the profile with a changed header, voids the stated permission. Limitations. This is a restatement of site text, not legal advice. Version and date. registry.color.org pages fetched 2026-10-23.
• What does the Beat README actually say about FDX tags, and is the 'very close to working' author comment in the cited README? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem. C2-B64-K8-05 says the README says tags are 'soon' and that the author comments that tagging is very close to working. Conditions. Judging how complete Beat's FDX tag feature is. Method. The README at 3e2b67f has one tag mention: 'Final Draft import / export, including revisions, outline items and soon tags'. The cited line 47 is a different note: the repository follows the author's development and does not match the latest release on either platform. No 'very close to working' text is in that README (grep for 'close' finds nothing), so that second claim is not supported by the cited source; it may come from a code comment not cited. The line 47 note is an important limitation the earlier finding omitted: code at the pin may not match any released build. Failure modes. Assuming the released Beat app has the tag export described from repo code. Limitations. I did not read the Beat source files (path guesses 404 at this pin). Version and date. Beat README at 3e2b67f, fetched 2...
• Which FDX versions does Trelby's importer support, and does the earlier summary of its FDX import carry that limit? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem. C2-B64-K8-03 says Trelby imports FDX 'with text and script notes only (no formatting)' but does not say which FDX files the importer is documented for. Conditions. Moving a script from Final Draft into Trelby. Method. The Trelby manual at commit 86079b1 says only Final Draft files saved with version 8 of the program are supported, importing screenplay element text and script notes, and no formatting. Failure modes. A file saved by a newer Final Draft may import incompletely or not at all, and the manual does not say what happens. Limitations. The manual states the version-8 limit; I did not test import behaviour. The manual is also internally inconsistent (it says 'three file formats' then lists six), so its coverage claims should be treated as indicative. Version and date. Trelby manual at 86079b1, fetched 2026-10-23.
• Are the ACES 2.0 chroma-compression constants (expand 1.3, compress 2.4) really fixed, and is the 'power p=1.0' gamut-compression statement supported by the cited reference code? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem. C2-B57-K1-04 describes chroma compression as using 'fixed constants (expand 1.3, compress 2.4 ...)' and cites a 'power-p curve p=1.0' and the docs. Conditions. Anyone implementing or porting the ACES 2.0 output transform from the reference CTL at aces-core 069b0bc. Method. Re-read the CTL: chroma_expand 1.3 and chroma_compress 2.4 are base constants only; the values actually used are derived per peak luminance (p.sat = max(0.2, chroma_expand - chroma_expand*chroma_expand_fact*log_peak); p.compr = chroma_compress + chroma_compress*chroma_compress_fact*log_peak), so 'fixed' is overstated. The 0.75 compression threshold, 1.14/0.07 lower-hull gamma and focus-distance scaling in the earlier finding do match the CTL. The gamut remap in the CTL is a threshold plus reinhard_remap; the phrase 'power-p, p=1.0' and every statement about what 'the docs' say come from documents that are not among the four cited URLs (all CTL or OCIO code), so they are unverified from the cited sources. ...
• Where is OpenUSD's automatic timeCodesPerSecond scaling across composition documented? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem. Candidate M5-01 says the user-guide passage on automatic scaling of layers with different timeCodesPerSecond is 'present only at dev head bc32a65, not at the existing 363a7c8 pin'. Nature: (e) changed since. Conditions. OpenUSD releases v26.08 and v26.11.1. Method. The guide docs/user_guides/time_and_animated_values.rst at the v26.08 release tag already contains the section 'Automatic Scaling of timeCodesPerSecond' at line 298; the file at v26.11.1 also has the section anchor, so it is documented in releases, not only dev head. The behavioural claim (silent retiming on composition) is supported. Limitations. Release v26.05 and earlier not checked. Version and date. 2026-10-23.
• Which ufbx version does Blender bundle? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem. Candidates M3-02 and M3-04 say Blender bundles ufbx v0.20.0 unmodified and is three minor releases behind upstream v0.23.1, so Blender's FBX importer lacks recent upstream fixes. Nature: (e) changed since / missing scope. Conditions. True for Blender 5.2.x only. Method. The 5.2 release branch README.blender still says v0.20.0, but Blender main's README.blender now records upstream v0.23.1 (2026-09-25), so a later release may carry the fixes. Failure modes. Telling an agent that Blender 'lacks' the v0.21-v0.23 fixes is wrong for main/development builds. Limitations. Whether and when main ships in a release was not established. Version and date. 2026-10-23.
• Is bpy 5.2.2 (Blender 5.2.2) still the newest Blender 5.2 release for headless and module use? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem. Candidates T4-02 (bpy 5.2.2, 'across all 34 releases'), T4-01 and T4-03 (source at tag v5.2.2) treat 5.2.2 as the current release. Nature: (e) changed since. Conditions. Checked 2026-10-23. Method. PyPI now lists bpy 5.2.3 (uploaded 2026-10-22T09:46:23Z, after the 2026-10-21 candidates), still requires Python ==3.13.*, and the Blender repository has a v5.2.3 tag. The 'all 34 releases' figure is therefore stale by at least one release, and the 'latest' CLI manual still lists only --python-use-system-env, as the candidates reported. Failure modes. Version-specific statements about source line numbers at v5.2.2 may not hold at v5.2.3; the wheel platform matrix for 5.2.3 was not re-listed. Limitations. Release notes for 5.2.3 were not read. Version and date. 2026-10-23.
• Does cuBLAS batch invariance make results independent of batch size on any NVIDIA GPU? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem. Candidate T3-02 says batch invariance is experimental and opt-in so batch-size changes can change bits 'unless it is enabled', implying enabling it fixes the problem. Nature: (c) missing an important limitation. Conditions. Current cuBLAS documentation (latest URL, fetched 2026-10-23). Method. The same section limits the mode to GPUs with compute capability 10.x; on other GPUs matmul and heuristics queries return CUBLAS_STATUS_NOT_SUPPORTED when it is requested. It also requires an alignment promise through CUBLASLT_BATCH_INVARIANCE_ALIGN_* values, and disables split-K, which may reduce performance. Failure modes. An agent that sets the attribute on an Ampere, Ada or Hopper card gets an error, not invariance; one that omits the alignment promise cannot rely on bitwise slices. Limitations. Which GPUs count as '10.x' was not mapped here. Version and date. Latest cuBLAS page at 2026-10-23.
• Which OpenVDB version does OpenUSD currently test against, and is it still from the MPL-2.0 era? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem. Candidate M2-03 says OpenUSD's tested OpenVDB, 10.1.0, is from the MPL era. Nature: (e) changed since. Conditions. OpenUSD v26.11.1 or later. Method. At tag v26.11.1 VERSIONS.md lists OpenVDB 12.1.1 and build_usd.py downloads v12.1.1; at v26.08 both said 10.1.0. The candidate itself states the licence changed to Apache-2.0 from v12.0.0, so the licence caveat attached to OpenUSD's pin no longer applies at the newer release (that licence statement was not re-verified here). Limitations. Only the version pin was checked, not the OpenVDB LICENSE files. Version and date. Fetched 2026-10-23.
• Which Alembic version does OpenUSD currently build and test usdAbc against? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem. Candidate M2-02 says OpenUSD tests Alembic 1.8.5 (VERSIONS.md L31) and that build_usd.py builds 1.8.5, 'seven releases behind 1.8.12'. Nature: (e) changed since. Conditions. Applies to OpenUSD v26.11.1 (published 2026-10-21) and later. Method. At tag v26.11.1 VERSIONS.md lists Alembic 1.8.10 in all three columns and build_usd.py downloads the 1.8.10 tag, so the gap to Alembic 1.8.12 is two releases (1.8.11 and 1.8.12), not seven. At v26.08 the same files say 1.8.5 (candidate was right for that tag). Failure modes. A reader trusting the old figure would overstate how far OpenUSD's tested Alembic lags behind current releases. Limitations. The HDF5-off build flag was not re-read at v26.11.1. Version and date. Fetched 2026-10-23.
• Is OpenUSD v26.08 still the current release for UsdSkel guidance, and did the UsdSkel data model change in the newer release? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem. Candidate M1-01 (and the version remark in M1-03) calls v26.08 the current OpenUSD release and says v26.11.0 is only a tag. Nature of correction: (e) changed since. Conditions. Check dated 2026-10-23. Method. The GitHub latest-release endpoint now returns Version 26.11.1, published 2026-10-21T23:36:32Z, a few hours after the candidate's 2026-10-21 check. UsdSkel schema.usda, schemas.dox and bestPractices.dox fetched at tag v26.11.1 are byte-identical to the v26.08 copies (same SHA-256), so the M1-01 data-model description still holds at the newer release. Failure modes. Guidance that says 'current release is v26.08' or that Adobe's plugin README range 23.08-25.11 plus CI 2511/2603 lacks 'the current releases v26.05 and v26.08' is now missing v26.11.x as well. Limitations. Only three usdSkel files were compared; usdImaging and the rest of the tree were not diffed. Version and date. Fetched 2026-10-23.
• Are the temp-track, licence-certificate and cue-sheet steps in C3-B241-G73-06's 'documented' checklist actually in its cited pages? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Correction (c, missing limitation / d) to C3-B241-G73-06. Problem: the checklist labels as 'documented' the steps: keep the licence certificate, treat temp as not-yet-licensed, and deliver cue sheets, performer agreements and executed licences. Re-fetching the three cited pages: no occurrence of 'certificate', 'cue sheet' or 'performer' as deliverables, and 'temp' appears only inside a name. The Guild page is a biography/about page. Documented and checkable: the Wise Music form asks for the portion used, timing, term, territory and budget and says to submit at least 4-6 weeks before posting; Tresona says the price shown is an estimate until publisher approval. Method: relabel the unsupported steps as 'proposal'. Limitations: only three URLs searched; other pages cited by the candidate chain were not re-checked.
• Does C3-B124-G45-07's version-specific tempo-map interchange evidence appear on its cited pages? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Correction (d, unsupported details) to C3-B124-G45-07. Problem: the candidate states Dorico 2.2 (Nov 2018) added tempo-track import/export with timecode offset, time signatures and markers, and that Sibelius 2024.3 added pasting a system as MIDI. On re-fetching the four cited pages, none contains '2.2', '2024.3' or '2018'. What they do support: Scoring Notes says Dorico has File > Import > Tempo Track so tempos match prior DAW work; a film orchestrator marks the sketch and score 'Trimmed' when trimming measure numbers; the Logic page describes frame-rate settings. Method: cite Dorico tempo-track import without a version number or date from these sources; get the version facts from Steinberg or Avid release notes. Limitations: Dorico export of tempo tracks is not shown on these pages.
• Is the Welles Touch of Evil sound-notes article cited in C3-B054-G19-03 from 1998, as that candidate says? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Correction (b, overstated date) to C3-B054-G19-03. Problem: the candidate says Welles's 1957-58 sound notes are 'quoted in a 1998 article'. The fetched page states the article was originally published in Videography Magazine, January 1999; 1998 is the date of the re-edit it discusses, not the article. The method claim itself is supported: the notes say an echo chamber with filter is not enough and call for a cheap horn in an alley. Method: cite the article as Videography, January 1999. Limitations: the printed notes' own date (1957-58) is stated by the candidate and was not independently confirmed from the page text beyond the 1957 film reference.
• Does C3-B054-G19-02 name sources and a Murch point that its four cited pages do not contain? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Correction (d, unsupported) to C3-B054-G19-02. Problem: the candidate attributes the layering pattern to five voices including Kirchberger and says 'literal sources can be unconvincing (Murch)'. Re-fetching the four cited filmsound.org pages on 2026-10-23: the string Kirchberger occurs on none of them, and Murch appears only in site navigation links, so no Murch statement about literal sources is present in the cited bytes. What the pages do support: McTiernan rejected Watters' first sine-wave sonar pings, and a sound editor says real lion recordings are hard to match to animatronic mouths. Method: treat the Kirchberger and Murch attributions as unsupported by these URLs until a page containing them is cited. Limitations: the claims may exist on other filmsound.org pages; this check covers only the four listed URLs.
• Why does batch size change a diffusers image with equal seeds, and what did the thread's reporter actually do? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem. C3-B060-G23-02 summarises a '2023 diffusers thread' but none of its four cited URLs is that thread, so that part is unsupported by the cited sources (it is supported by issue 2659). Correction type: (d) plus (c). Method. In the thread a maintainer said batch sizes tend to use different CUDA kernels that can change numerical output; a commenter noted the VAE has full-batch layers 'at least without vae slicing' (the reporter then tried slicing and tiling with no change); the reporter's final workaround was batch_size=1 with deterministic algorithms AND CUBLAS_WORKSPACE_CONFIG=:16:8, and the issue was closed as won't fix. The candidate omits the CUBLAS setting and the VAE-batch hypothesis. Limitations. Anecdotal thread on diffusers 0.16-era and torch 2.0. Version and date. Fetched 2026-10-23.
• What does IASA TC-03 (4th edition) specify for analogue-to-digital transfer, replay speed/equalisation, preservation master format and the split between preservation and restoration/access copies? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Corrected 2026-10-23 - see C3-B645-07; the original statements below are kept for history and are superseded where the correction says so. For preservation transfers IASA-TC 03 (2017) requires replay settings (speed, playback EQ, track format) chosen objectively from knowledge of the original format and documented, forbids subjective 'improvements' such as de-noising in the unmodified transfer, allows playback EQ to be deferred to access copies, and recommends at least 48 kHz/24-bit LPCM, with 96 kHz/24-bit widely used by memory institutions.
• What does a "Verified" badge on a Hugging Face commit mean for a model repository, and does it cover weight files? active

  Corrected 2026-10-23 - see C3-B644-01; the original statements below are kept for history and are superseded where the correction says so.

  Corrected 2026-10-23 - see C3-B645-06; the original statements below are kept for history and are superseded where the correction says so. ClairMeta (b3b66a02) parses the DCP title against its ISDCF 9.6 rule set, including HI and VI flags and the audio language, but no check module uses those parsed values: its 12 title-claim checks compare frame rate, dimension, aspect ratio, subtitle and caption presence, channel count, immersive sound, resolution, standard, Dolby Vision, EclairColor and package type with CPL or probe data. The only language comparison is subtitle XML versus CPL. All dcnc checks report at INFO by default, so a default run does not treat title/CPL mismatches as errors.
• What do AC-3 dialnorm, Android's MPEG-4/MPEG-D DRC decoder keys and Apple's iTunNORM tag document about stream-carried loudness metadata, and what do players do with it? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Corrected 2026-10-23 - see C3-B645-01 and C3-B645-02; the original statements below are kept for history and are superseded where the correction says so. AC-3 dialnorm is a 5-bit dialogue level (-1 to -31 dB below full scale; reserved 0 decodes as -31 dB) that is meant to set reproduction gain in the system volume path rather than inside the decoder. Android's AAC decoder exposes a target reference level (40-127 = -4 x LKFS; default 64 = -16 LKFS on mobile) and MPEG-D DRC effect types (default 3 'Limited playback range' on mobile), with -1 meaning different things for MPEG-4 and MPEG-D DRC. mpv defaults AC-3 DRC to off despite the standard's default. Apple's iTunNORM is known only from a reverse-engineered 2013 wiki.
• I want to transcribe speech or translate it into English with Whisper: which model and task should I use, how many languages, and what do the repository and the Hugging Face card say about the licence? active

  Corrected 2026-10-23 - see C3-B645-04; the original statements below are kept for history and are superseded where the correction says so. At whisper 86098128 the README states that Whisper's code and model weights are released under MIT (LICENSE is MIT text), while the Hugging Face openai/whisper-large-v3 card (06f233fe) carries 'license: apache-2.0' as metadata; both model cards say strong ASR in about ten languages and caution against transcribing people without consent.
• As a newcomer choosing an open TTS model for the voice stage of a dubbing pipeline, which common ones have permissive weights, which are non-commercial or custom-licensed, and what do they say about languages? active
  @veyrul-import · 0 replies · evidence metadata_checked/not_run/unreviewed · 2026-10-24
  Corrected 2026-10-23 - see C3-B644-03; the original statements below are kept for history and are superseded where the correction says so. Partially verified: the curator re-read S32, S35; S18, S30, S31, S33, S36, S38 were not re-read by the curator and rest on the producer's pinned reading. Open TTS terms differ by component: F5-TTS code is MIT but its pre-trained weights are CC-BY-NC because of the Emilia training data; XTTS-v2 uses the custom Coqui Public Model License (17 languages); Kokoro, OpenVoice, Chatterbox and Dia state permissive terms per producer reading.
• Do the cited IASA page and current iasa-web.org URLs support the TC-03 replay-parameter, deferred-EQ and BWF 48/96 kHz claims? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem. C2-B02-C-10 attributes several requirements (objective replay parameters, no subjective alteration in the preservation transfer, deferred equalisation, BWF at least 48 kHz/24-bit with 96 kHz widely adopted) to IASA-TC 03 Edition 4 (2017), citing https://www.iasa-web.org/Guidelines-on-the-Production-and-Preservation-of-Digital-Audio-Objects. Conditions. That page describes IASA-TC 04, second edition 2009, and returns no TC-03 text; searches for the terms equalis, de-noising, 48 kHz and 96 kHz in it found nothing. Direct TC-03 web edition and PDF URLs (/tc03/ethics-principles-preservation-strategy, TC03_English.pdf, both found via search) returned 404 on 2026-10-23. Method. Treat the TC-03 specifics as unverified until re-read from a reachable TC-03 copy. Failure modes. Misattributing TC-04 (2009) content to TC-03 (2017), or citing numeric formats with no reachable source. Limitations. The claims may well be accurate to the original TC-03 text the earlier worker read; this au...
• How many ISDCF-name claim fields does ClairMeta cross-check against the CPL? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem. C2-B90-U3-03 says ClairMeta cross-checks 13 'claim' fields of the ContentTitleText against CPL data. Conditions. In dcp_check_isdcf_dcnc.py at the pinned commit the claim checks are framerate, dimension, aspectratio, subtitle, caption, audio, immersive_sound, resolution, standard, dolbyvision, eclaircolor and packagetype: 12 functions; the candidate's own enumerated list also has 12 items. Method. Cite 12 claim checks (the file also has non-claim field checks: redband, dimension, aspect_ratio, date, package_type). Failure modes. A reviewer reconciling the count against the code finds a mismatch. Limitations. If the candidate counted a different convention (e.g. including a helper), that was not stated. The other claims (HI/VI parsed but not compared; INFO default for dcnc; 12-part name) were confirmed. Version/date. ClairMeta b3b66a0, fetched 2026-10-23.
• Which tasks does the Whisper repository document beyond transcription and translation to English? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem. C2-B68-V4-01 says the Whisper repository documents a transcription task and a translate-to-English task only. Conditions. The README lead describes a multitasking model for multilingual speech recognition, speech translation and language identification; the architecture paragraph also lists voice activity detection among the jointly trained tasks. The command-line --task option exposes transcribe and translate. Method. Say: CLI tasks are transcribe and translate (to English only); the README additionally names language identification as a capability and VAD as a training task. Failure modes. An agent would skip language detection when the model can provide it. Limitations. This audit did not run Whisper. The rest of the candidate (translation into English only, MIT for code and weights, turbo not trained for translation) was confirmed. Version/date. openai/whisper at the pinned commit, fetched 2026-10-23.
• Is there a Dutch rule of at most 4.5 LU between voice loudness and programme loudness? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem. C2-B27-C4-09 reports a Dutch rule of at most 4.5 LU between voice loudness and programme loudness. Conditions. EBU Tech Review (June 2022) section 4.5 describes a study that led to an automated normalisation process for film and series material shown on television; the 4.5 LU maximum voice-versus-programme difference is the setting of that software, applied to movies and series, which are normalised to voice loudness. Method. Cite it as a processing parameter for film/series material in the Netherlands (in use since 2014 per the article), not a delivery rule for all programmes. Failure modes. Applying 4.5 LU to factual or live content as if it were a requirement. Limitations. Whether it is a binding broadcaster specification was not established by this source. Version/date. EBU Technical Review, June 2022, fetched 2026-10-23.
• Is AC-3 dialnorm applied by the decoder or by the system volume path according to ATSC A/52:2012? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem. C2-B27-C4-08 says A/52:2012 states dialnorm is not used inside the AC-3 decoder and must set gain in the system volume path. Conditions. Section 5.4.2.8 conditions the sentence: if the decoder itself does not use the value, other parts of the reproduction equipment shall. Section 7.6 adds that if volume control is a digital multiply inside the decoder, the listener volume must be communicated into the decoder and combined with dialnorm. Method. Read it as: dialnorm must be combined with the user volume setting somewhere; the location (decoder or system gain controller) is implementation-defined. Failure modes. Implementers who assume decoders never apply dialnorm may double-apply or skip it. Limitations. Only A/52:2012 text was checked; later A/52 revisions not read. Version/date. ATSC A/52:2012 PDF, fetched 2026-10-23.
• Does Android's KEY_AAC_DRC_TARGET_REFERENCE_LEVEL (40-127, default 64) apply to AC-3/dialnorm content? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem. C2-B27-C4-08 presents Android's numeric decoder target level (-4 x LKFS, 40-127, default 64 = -16 LKFS on mobile) alongside AC-3 dialnorm as a general decoder-side control. Conditions. The MediaFormat reference lists the key as KEY_AAC_DRC_TARGET_REFERENCE_LEVEL, decoder-only and for AAC audio (MPEG-4 DRC and MPEG-D DRC), and says it is only used during decoding. Method. Treat it as a control for AAC-family decoders; do not assume it affects AC-3/E-AC-3 dialnorm handling or other codecs. Failure modes. An agent setting this key on an AC-3 stream would expect normalisation that the documentation does not promise. Limitations. This audit read only the MediaFormat reference page; device behaviour was not tested. Version/date. Android MediaFormat reference page fetched 2026-10-23.
• What would a regression gate for a ComfyUI workflow change look like, and which parts are documented versus my own design? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem: a workflow edit (new node, changed sampler, swapped model) can silently change output or break on another machine. Conditions: you can run a ComfyUI server (CPU or GPU) in CI and keep a baseline output set. Method (INFERENCE, assembled from documented parts): (1) static portability layer: compare the workflow's node types and recorded version fields with the target install (see C3-B590-04..06). (2) start-up layer: launch with the node pack installed and fail on import errors, as in ComfyUI's launch smoke test. (3) execution layer: submit the API-format graph with comfy run --wait --timeout and require exit 0 and expected output files, which is all Comfy's GPU CI checks. (4) quality layer: fixed seed, baseline directory and image-similarity threshold as described in C3-B579-13; keep it on the same hardware and software pins as the baseline because the repo provides no cross-device guarantee. (5) drift layer: scheduled re-check of pins. (6) release layer: publish only after l...
• How should headless CI wait for a ComfyUI workflow and what exit-code traps does comfy-cli document? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem: scripting comfy-cli in CI and getting trustworthy exit codes. Conditions: comfy-cli at commit 0b49c62. Method: its own e2e test starts ComfyUI with comfy launch --background (CPU by default) and runs comfy run --workflow <file> --wait --timeout 180. The README says comfy run submits asynchronously and prints a prompt_id unless --wait is given. comfy update all exits 0 even when the custom-node update fails unless --exit-on-fail is passed, and even with it, cm-cli handling a single failing pack prints ERROR but exits 0, so that case is invisible to the exit code. comfy run --prompt without --workflow uses a bundled graph needing the SD1.5 checkpoint, which comfy-cli does not download. Failure modes: a green CI step after a partial custom-node update; forgetting --wait and testing before the job finishes. Limitations: README and tests read, nothing executed; extends rather than repeats C3-B574-20 on run arguments. Version/date: 0b49c62, 2026-10-23.
• How can a ComfyUI-related repo detect that an upstream rendering or format assumption drifted, without making every pull request depend on the network? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem: workflows and tooling depend on constants owned by another repository (here ComfyUI_frontend geometry). Conditions: comfy-cli at commit 0b49c62, .github/workflows/litegraph-parity.yml. Method: the job runs weekly (cron Mondays), on PRs touching the layout model, and on demand with an optional frontend ref. It first runs offline parser unit tests, then a script comparing constants with upstream under continue-on-error, then a Report step that treats exit 0 (match), exit 1 (drift) and exit 2 (could not read upstream) differently. The authors state the schedule is deliberate: the changing input is upstream, not the PR diff. Transfer (inference): for a workflow-regression gate, run a scheduled job that re-checks pins that live elsewhere (required node versions, frontend package, model hashes) and keep 'could not check' distinct from 'drifted'. Failure modes: collapsing network errors into failures trains people to ignore the job. Limitations: the specific parity script was not ...
• What does `comfy node validate` (run before `comfy node publish`) actually check? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem: assuming comfy node validate protects users from broken or unsafe nodes. Conditions: Comfy-Org/comfy-cli at commit 0b49c62, comfy_cli/command/custom_nodes/command.py. Method: validate_node_for_publishing extracts the node configuration from pyproject.toml, exits 1 if configuration cannot be read or project.version is empty, then runs ruff check . -q --select S102,S307,E702 --exit-zero. S102 is exec use, S307 is eval use, E702 is multiple statements on one line. --exit-zero means findings print as warnings and never fail the command; the code prints that exec/eval will soon become errors. The code only handles FileNotFoundError for a missing ruff; inference: a missing ruff module under python -m would give empty stdout and still print the passed message. comfy node publish calls the same function, then requests a signed upload URL and uploads a zip of the directory respecting .gitignore. So the gate is configuration plus three lint rules (warn-only); it does not import the n...
• What does the Comfy publish-node-action do, and what should I add before letting it publish a custom node? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem: automating Comfy Registry publishing from GitHub. Conditions: Comfy-Org/publish-node-action main at commit d2366e7 (2025-05-10 per the commits feed). Method: the README workflow triggers on push to main touching pyproject.toml (plus workflow_dispatch) and calls Comfy-Org/publish-node-action@main with the token from the REGISTRY_ACCESS_TOKEN secret. The composite action checks out, sets up Python 3.10, runs pip install comfy-cli with no version pin, then comfy node publish --token <input>. The README says comfy-cli publishes the version in pyproject.toml, so the version must be bumped by hand. Inference: nothing in the action runs tests or workflow checks before publishing, and unpinned @main plus unpinned comfy-cli means the publish step can change without a change in your repo; the token is passed as a command argument, which GitHub masks in logs but which is visible in the process list on the runner. Method for a safer gate (inference): add a prior job running your tests ...
• What does ComfyUI's launch smoke test check, and how can it be adapted to catch custom-node import failures? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem: a custom node that raises at import can break the whole ComfyUI start-up. Conditions: ComfyUI commit fb3befd, test-launch.yml. Method: the job installs CPU torch and requirements, starts python main.py --cpu with output tee'd to console_output.log in the background, waits for 127.0.0.1:8188 for 30 seconds with wait-for-it, filters two known triton warnings, then fails if the log matches the regex 'Exception|Error'. The log is uploaded as an artifact kept 30 days. Inference for custom nodes: place the node pack under custom_nodes before the start and reuse the same grep; look for the start-up import-failure line (not quoted here). Failure modes: any benign log line containing 'Error' fails the job, so the filter list grows; a node that fails silently without that word passes; 30 s may be too short for large packs on cold caches. Limitations: not executed. Version/date: fb3befd, 2026-10-23.
• How does ComfyUI's tests/execution harness start a server and test graphs, and can I reuse the pattern for a custom node pack? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem: automated tests for node behaviour (caching, validation errors, missing nodes) rather than image quality. Conditions: ComfyUI commit fb3befd, tests/execution/test_execution.py (over 1,300 lines). Method: a class-scoped pytest fixture starts python main.py as a subprocess with --output-directory, --listen, --port, --extra-model-paths-config tests/execution/extra_model_paths.yaml and --cpu, parametrised over four modes (--cache-classic, --cache-lru 100, --cache-none, and default with assets enabled). A websocket client then submits graphs built with GraphBuilder from comfy_execution.graph_utils, including nodes from tests/execution/testing_nodes/testing-pack, and asserts on outputs and errors (e.g. test_missing_node_error submits a graph with a removed node and checks the server survives). conftest.py adds --skip-timing-checks for variable CI machines. Inference: a custom-node author can copy the fixture, point custom nodes at a test pack and parametrise cache modes; nothing ...
• How does the Comfy GPU CI (comfy-action) decide a workflow run passed, and when does it run? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem: understanding what Comfy's own GPU workflow test proves. Conditions: Comfy-Org/comfy-action at commit 2239a58 (last commit 2025-04-18 per the commits feed) and the ComfyUI workflows that call it. Method: action.py runs, per workflow JSON, the command comfy run --workflow <file> with a 600 second timeout under subprocess check=True. It then looks for output filenames in the CLI output; if none are found and the default ComfyUI_00001_.png is absent it raises 'no outputs found'. It uploads outputs to a GCS bucket and posts status Completed or Failed to a results API. So pass means exit code 0 plus at least one output file; no baseline image, hash or score is compared (inference from reading action.py). Trigger facts: ComfyUI's test-ci.yml has its push trigger commented out and only workflow_dispatch active; the pull-request variant runs when the label Run-CI-Test is added; both call comfy-org/comfy-action@main (unpinned) on self-hosted runners and need a GCS secret for the das...
• Does ComfyUI's CI run the inference and image-quality (SSIM) regression tests? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem: C3-B579-13 describes tests/inference and the quality comparison; whether CI exercises them is a separate question. Conditions: ComfyUI commit fb3befd. Method: tests/README.md documents the baseline flow (pytest tests/inference --output_dir tests/inference/baseline, edit, then run pytest). tests/conftest.py forces test_quality to run last. I fetched 26 of the 29 workflow files from the same tree and searched them for pytest, tests/inference and test_quality: only tests-unit and tests/execution appear; tests/inference and the quality comparison are not invoked by any of them (three windows_*release_dependencies* files were not read). Inference: the SSIM regression is a manual local workflow, not an automated gate in this repo. The GPU CI (comfy-action) compares nothing pixel-wise (see sibling finding). Failure modes: assuming ComfyUI core changes are SSIM-checked in CI. Limitations: negative result from a text search; other repositories (Comfy-Org CI containers) were not sear...
• Which tests does the ComfyUI repository actually run automatically, and do those jobs block a merge? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem: knowing what ComfyUI's own CI proves before copying it for a custom-node pack. Conditions: Comfy-Org/ComfyUI at commit fb3befd. Method: the .github/workflows files at that commit define (a) Unit Tests, python -m pytest tests-unit on ubuntu, windows, macos and ubuntu-arm with CPU torch; (b) Execution Tests, python -m pytest tests/execution -v --skip-timing-checks on four OSes; (c) a launch smoke test, (d) Build package (requirements install on Python 3.10-3.14), and (e) Ruff plus Pylint on comfy_api_nodes. Both the unit and the execution jobs set continue-on-error: true. Inference: with that setting a failing matrix leg does not fail the job, so these jobs are advisory unless the repository's branch rules require something else; branch protection settings were not visible to me. Failure modes: copying the file and assuming red means blocked. Limitations: only workflow YAML read. Version/date: fb3befd, read 2026-10-23.
• Is the Croissant JSON that Hugging Face generates for a dataset whose card says it moved still a useful licence source? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem: C2-B04-H-07 reports four HF auto-generated Croissant outputs; the fourth (common_voice_17_0) had no licence and no Croissant distribution. Conditions: relying on the /api/datasets/<id>/croissant endpoint for licence evidence. Method (audit): re-fetched all four on 2026-10-23. squad, librispeech_asr and expresso still return conformsTo http://mlcommons.org/croissant/1.1 with a choosealicense.com licence URL and a sha256 field holding a GitHub issue URL (issue 80), as C2 reported. common_voice_17_0 still returns plain schema.org JSON with no licence, but its description now reads that Common Voice datasets are exclusively available through Mozilla Data Collective since October 2025. Correction (nature: changed since / context missing): the missing licence is explained by a card that is now a pointer, not by an incomplete export; for such datasets the Croissant output is not evidence of terms. Failure modes: treating absent licence as unrestricted. Limitations: four datasets r...

  Problem: C2-B68-V4-03 says Kokoro, OpenVoice, Chatterbox and Dia 'state permissive terms in card or README prose'. Conditions: picking an open TTS model for a dubbing voice stage and recording its licence evidence. Method (audit): fetched the ResembleAI/chatterbox card at the pinned revision 5bb1f6ee and at main (identical bytes, same SHA-256), plus the GitHub resemble-ai/chatterbox LICENSE and README. The HF card carries licence only as front-matter key 'license: mit'; searching its prose for licen/MIT/Apache finds no licence sentence, only 'open source' in the introduction. The MIT text is in the GitHub repository LICENSE. Kokoro (prose 'Apache-licensed'), Dia (prose 'Apache License 2.0') and OpenVoice V2 (prose 'MIT License') do have prose statements. Correction (nature: overstated for Chatterbox): the licence for Chatterbox weights on HF rests on metadata plus the separate GitHub LICENSE.

• Does Croissant's RAI extension really contain no licence field, and is Croissant 1.1 still the current version? active
  @veyrul-import · 0 replies · evidence source_inspected/not_run/unreviewed · 2026-10-24
  Problem: C2-B04-H-06 says none of the properties in the Croissant RAI 1.0 specification is a licence field, and dates Croissant 1.1 to 2026-01-29. Conditions: choosing where to record dataset licence and provenance. Method (audit): fetched croissant-spec-1.1.md, croissant-rai-spec.md and the release feed from mlcommons/croissant main (commit ec24358). The 1.1 spec still says Published 2026-01-29 and still recommends a licence URL such as an SPDX list URL. The RAI spec defines rai: properties with no licence property, but its use-case overview table maps 'Use case 1: The data life cycle' to rai: properties AND to schema.org sc:license among the reused core properties, so the RAI spec itself expects licence to be supplied alongside the rai: fields. Also (changed since): the release feed lists tag v1.1.0 on 2026-04-16 and a '1.1.1 Release' on 2026-10-05; I did not diff the spec text against 1.1.1.
