Docs: gaps.md records the community fixes of 7 October (#135, #139, #141, #142)

The ui_angles evidence (#141) moves next to G2's other regression
evidence; the Stability row notes the parent-chain hang, the label colour
panic and the contained GPU failures.

 | Breadth of features | ≈ 95%+ | All 306 effects, the After Effects menus and panels, Classic and Advanced 3D, tracking, expressions, scripting, render queue (parity.md) |
 | Behaves like After Effects | largely unmeasured, ≈ 60–80% | One outside contributor found four bugs in features marked done within a day (PRs #6–#10): Hold keyframes eased the motion into them, `keyInSpatialTangent` / `keyOutSpatialTangent` had the wrong names, a zero frame rate crashed, Find and Enter Full Screen shared Ctrl+F off macOS. There are about 10 After Effects reference captures in total. The first live G1 comparison now checks eight scalar Rotation/ease cases (168 samples) against AE 26.3x87 via AEsync 2.0.4: all pass after fixing overlapping temporal influences, with maximum error below 3e-11 degrees ([scores and reproduction](fidelity/README.md)). Other animation behavior and rendered frames remain unmeasured. User reports of 6 October found five more in features marked done (the Render Queue's template menu, angle revolutions, switches wiping the RAM preview, audio playback skipping frames, preview crashing when video memory ran out; all fixed 7 October) |
 | Opening existing After Effects work | ≈ 0% | `.aep` / `.aepx` projects cannot be opened. Third-party After Effects plug-ins cannot run. Expressions and the scripting object model are strong, so scripts and expressions carry over |

+| Stability | improving | 23 never-crash PRs landed on 4 October; community PRs on 7 October fixed a hang on projects whose parent chains loop (#142), a panic on non-ASCII label colours (#135), and contained GPU initialization and device failures (#139); [AGENTS.md](../AGENTS.md) "Never crash" now binds every crate.

 | Real-user experience | ≈ 70%, uneven by platform | Issues #41–#47 (all from the Linux AppImage 0.1.1, 5 October): panning the viewer snaps back, panels can't be resized or rearranged, drag-and-drop and double-click import don't work, layer rename gets stuck, the Layer Settings arrow does nothing, the Project panel clips, the Wayland window icon is generic. Issues #63–#68 (macOS, 5 October): scaling a layer by its handles goes wrong and can stick at 0, two 3D compasses, the viewer lags while a layer is dragged (a frame renders in 20 ms but showed after ≈ 100 ms, behind RAM preview prefetch), the Discord and other links do nothing, Delete doesn't delete in the Project panel, hidden layers can be selected in the viewer. All but the last two were fixed or confirmed fixed with a test on 5–6 October (those two have community PRs); file drops still can't work on Wayland (winit has no support). The panning, rename and arrow bugs had been fixed in v0.2.0 already; nobody had told the reporter. A Windows user (6 October, on Discord) found the font menus listed only the three bundled fonts: installed fonts were read only when a project asked for one, on every platform. Fixed with a regression test on 6 October; the menus now list every installed family and its own styles, and agents get `text.fonts` / `list_fonts`. Seven reports of 6 October (Linux .deb and Windows): Project items and files couldn't be dropped on the viewer (#85), nor effects on a layer there (#88); drops in the Timeline ignored where they landed (#89); an angle's revolutions couldn't be edited (#93); toggling Audio, Lock or Shy threw away the RAM preview and playback with audio skipped frames (#103); running out of video memory panicked every frame thread and left frames stuck (#106); choosing a Render Settings template in the Render Queue did nothing (#117: any popup menu moved up to fit the window closed on the press). All seven were fixed with regression tests on 7 October. Most checking happens on macOS. No localisation, no accessibility work |
 | Performance | unknown against After Effects | Internal numbers only (e.g. Advanced 3D 290 ms/frame at 1080p on the GPU, an M4 Pro under load). Nothing benchmarked against After Effects; no large real projects (4K footage, hundreds of layers) tested |
 | Media formats | ≈ 80% | H.264, ProRes, HEVC, AV1, image sequences and audio exist. The new HEVC / AV1 encoders have no B-frames, multi-reference or SAO / CDEF, so files are larger than from mature encoders. Camera formats (BRAW, R3D, ProRes RAW, variable-frame-rate phone video) are unverified |
