* feat(forks): LTX Director v2_0_2 fork + keyframe latent-grid snap (#258)

Bump the WhatDreamsCost Koolook fork to upstream 2.0.2 (pinned fe09f73) in a
new versions/v2_0_2 namespace, and add `snap_keyframes_to_grid` (default on)
to fix hard-pinned image keyframes "jumping" at latent-bucket edges.

Why: a Director image keyframe is injected as a single latent frame at the
segment's left edge, quantized to the model temporal stride s
(L(f)=0 if f==0 else 1+(f-1)//s). Pins near a bucket boundary round
ambiguously and two pins in one bucket collide. Snapping each pin to its
bucket center removes the ambiguity without changing which latent frame it
lands on; colliding pins are bumped to the next free bucket with a warning.

- forks/whatdreamscost_koolook/versions/v2_0_2/: vendored 2.0.2 sources with
  the v1.3.9 Koolook deltas carried forward (relay_overrides,
  audio_transcript_json, per-segment sigma — build_segments is byte-identical
  1.3.9->2.0.2 so the sigma patch drops in verbatim), plus new pure
  keyframe_grid.py snapper wired into the insert_frames build.
- Canonical LTXDirector__koolook rolls to 2.0.2 (entrypoint loads v2_0_2
  last); LTXDirector__koolook_v1_3_2 alias preserved; v1.3.9 kept on disk.
- LICENSE re-verified GPL-3.0 (2026-06-22). Manifest + THIRD_PARTY + CHANGELOG
  + audio-lipsync findings/CHEATSHEET updated.
- 37 new unit tests for the snapper; 107 fork tests pass.

* fix(forks): append Koolook LTX Director widgets last for clean load

Move the v2_0_2 Koolook widgets (relay_overrides, audio_transcript_json,
snap_keyframes_to_grid) to the end of the schema, after override_audio. They
were inserted after img_compression, which shifted the last upstream widget
when an upstream-2.0.x-saved workflow is loaded onto LTXDirector__koolook.
With them last, an upstream graph's positional widgets_values map onto the
upstream widgets untouched and only the Koolook widgets append with defaults
(snap_keyframes_to_grid=on). Execution is unaffected (kwargs by name).

* refactor(forks): make v2_0_2 a clean upstream-2.0.2 replica + grid-snap only

Per maintainer direction: the v2_0_2 Koolook LTX Director should faithfully
replicate upstream 2.0.2 (so all latest features work) rather than carry the
older customizations, which are unused.

- Drop relay_overrides, audio_transcript_json, and the per-segment sigma patch.
  prompt_relay.py and patches.py are now vendored VERBATIM from upstream 2.0.2;
  _relay_overrides.py removed.
- ltx_director.py is upstream 2.0.2 verbatim except two additive changes:
  the namespaced node ID LTXDirector__koolook, and the snap_keyframes_to_grid
  latent-bucket keyframe snap (issue #258), appended last in the schema.
- v2_0_2 registers only LTXDirector__koolook; the legacy
  LTXDirector__koolook_v1_3_2 ID stays backed by the v1_3_9 package. v1.3.9
  (with the older customizations) remains on disk for rollback.
- Manifest / THIRD_PARTY / UPSTREAM_PIN / CHANGELOG updated to the clean scope.
  grid-snap unit tests unchanged (107 fork tests pass).

* feat(forks): vendor upstream 2.0.2 timeline editor JS for LTXDirector__koolook

The v2_0_2 Python was upstream-exact but the node still rendered with the old
1.3.9-era timeline editor (fewer toolbar actions, no IC-LoRA track, leaked
*_second widgets, frame_rate NaN). Replace web/whatdreamscost_koolook/
ltx_director.js with upstream 2.0.2's js/ltx_director.js vendored verbatim,
retargeted with only two edits: unique extension name 'LTXDirector_Koolook'
and node guard nodeData.name === 'LTXDirector__koolook'. UX now matches
upstream 2.0.2 exactly; only the Python differs (grid-snap).

The old koolook base64-scrub deltas are dropped as obsolete — upstream 2.0.2
persists timeline media via imageFile/audioFile + /api/view URLs (saved
timelines are already lean), and the localStorage quota guard stays in the
global web/koolook_draft_guard.js (upstream does not override localStorage).

Rewrote tests/sidebar/test_ltx_director_draft_guard.py to the new contract
(no embedded guard, retargeted to the koolook node, pinned-upstream
provenance). 110 fork+contract tests pass.

* fix(scripts): resolve .env from main repo when dev-sync runs in a worktree

Unrelated to the LTX work: plain `dev-sync` failed with "KOLOOK_COMFYUI_DEV_PATH
not set" from any worktree because scripts/sync_to_dev.py only loaded
`.env` from the worktree root, where the committed `.env` does not exist
(it lives in the main checkout). sync_to_dev_audio.py already had the
worktree->main fallback, which is why dev-sync-audio worked.

Move that fallback into a shared sync_to_dev.find_dotenv() and use it in both
scripts so they can't drift. Adds regression tests for the worktree fallback,
the worktree-own-.env preference, and the not-a-worktree case.

* chore: gitignore root-level generated workflow JSONs

Node-swapped/converted workflow copies (e.g. *.koolook.json) are dropped at
the repo root during dev iteration; they're scratch deliverables, not package
content. Ignore root-level *.json only (leading `/`), with a `!config.json`
exception, so the 30+ tracked JSON in subdirs (test fixtures, web/, .claude/,
docs/runs/*/workflow.json) stay tracked.

* feat: LTX A/V Bind Schedule node — gate audio→video binding by sigma

New Koolook node LTXAVBindSchedule decouples big motion from lip-sync in LTX
2.3. The AV transformer (comfy/ldm/lightricks/av_model.py, BasicAVTransformerBlock)
adds audio into video via a gated `audio_to_video_attn` per block, run only when
transformer_options["a2v_cross_attn"] is set. This node patches each block's
audio_to_video_attn.forward to scale its output by a per-step gain, and a
unet-function-wrapper computes that gain from the current sigma: early/high-sigma
steps run near `early_gain` (coarse motion settles audio-blind), ramping
(smoothstep) to full at low sigma (lips bind onto settled motion). One pass, no
re-noise — the fix for keyframe transitions jumping on audio peaks.

early_gain=1.0 reproduces stock behavior; a graph without the node is unchanged.
Registered as a root node + added to RUNTIME_PATHS so dev-sync ships it. Pure
ramp (a2v_gain) unit-tested (9 cases); model wiring validated by live render.

* feat: LTX A/V Bind Schedule — add transition-window mode (lips synced + smooth)

The global sigma ramp decoupled motion from lips but desynced the mouth (lip
timing is coarse motion too, so holding audio out globally moved the mouth
audio-blind). Add a WINDOWED mode: audio binds at full strength everywhere
(lips sync across the whole clip) EXCEPT a +/-transition_window band around each
keyframe transition, where the sigma ramp applies — so only those moments are
motion-protected early and rejoined late.

Implemented as a per-latent-frame gain on a2v_out: read grid_sizes from
transformer_options to map frame-major video tokens -> latent frames, build a
gain vector (1.0 outside bands, smoothstep-tapered to sigma_gain at each
transition center), expand per-frame -> per-token, scale. New optional inputs:
transition_frames, total_frames, transition_window. Empty transition_frames =
prior global-ramp behavior. windowed_frame_gains unit-tested (7 cases).

* feat: LTXAVBindSchedule — one-shot diagnostic log (shapes/grid/mode)

Logs out.shape, grid_sizes, transition_fracs, and whether the per-frame mask
fired vs fell back to scalar — so a single render reveals whether the a2v patch
hooks the model and whether the windowed token->frame mapping aligns, instead
of guessing blind.

* docs(audio-lipsync): record validated a2v bind-schedule knee (0.35/0.25/0.55)

Promote the finding that LTX 2.3's audio->video coupling must be sigma-ramped
(not full-on) to keep motion smooth AND lips synced, with the validated knee
early_gain=0.35 / bind_start=0.25 / bind_end=0.55 on the 8-step base pass, plus
the trade-axis table and the per-frame-mode caveat (grid_sizes None + appended
guide frames -> scalar fallback).

* feat(forks): keyframe ease — strength-ramped neighbor pins to de-robotic transitions

Adds `keyframe_ease` / `ease_falloff` to the Koolook LTX Director (default off).
Each hard image pin keeps its exact center pose, but emits same-pose neighbor
pins one latent bucket apart at decreasing strength (center*falloff**k), so the
model glides into and out of the locked pose instead of snapping to a dead stop
— softening the "stop/dissolve/stop" robotic feel without softening the pose.

Implemented as a pure list expansion (`expand_keyframe_ease` in keyframe_grid.py,
6 unit tests) applied to guide_data after grid-snap, so the upstream guide node
is untouched (no fork). Center stays exact; neighbors that fall off-clip or onto
another center are skipped. Costs extra guide frames (more compute), hence opt-in.

* docs(audio-lipsync): downgrade a2v knee to 'promising' — note lows-placement confound

The 0.35/0.25/0.55 win was measured on a clip whose transitions sit on audio
lows, so 'no jumps' may be the placement, not the node. Mark the controlled
on-peak test (early_gain 1.0 vs 0.35 on the same on-peak layout) as still pending.

* chore: mark vendored WhatDreamsCost fork files linguist-vendored

The koolook Director ships upstream 2.0.2 code (the 8.5k-line timeline-editor JS
+ verbatim prompt_relay/patches) so the pack runs and distributes, but it's
upstream, not authored here. Mark those linguist-vendored (drop from language
stats) and the JS -diff (collapse the large blob in PR diffs). Our edited/new
files stay attributed to us.

* fix(ltx-av): drop unused `import math` (ruff F401)

a2v_gain uses an explicit smoothstep polynomial, not math.*, so the
import was dead. Unblocks the Lint & Smoke CI gate.

* ci(codeql): advanced setup that excludes vendored upstream code

CodeQL default setup cannot read a config file, so it scanned the
verbatim-vendored WhatDreamsCost editor (web/whatdreamscost_koolook/
ltx_director.js) and raised 4 high-sev DOM-XSS alerts in upstream code we
do not own. Switch to advanced setup with a committed config whose
paths-ignore mirrors the .gitattributes linguist-vendored block, so the
scanner treats vendored upstream as out-of-scope while still fully
scanning our own nodes and sidebar JS.

Languages match the prior default-setup matrix (actions,
javascript-typescript, python).

NOTE: requires disabling "default setup" once in repo Settings before
this workflow can run (GitHub rejects advanced runs while default setup
is enabled).

malkuthroandClaude Opus 4.8 447465ecd8 refactor(nodes): remove superseded LTX Director extra nodes + harden registry (#198) (#199)
* refactor(nodes): remove superseded LTX Director extra nodes + harden registry (#198)

Remove the two experimental nodes layered on the WhatDreamsCost fork — KoolookAudioTranscriptTimeline (k_audio_timeline.py) and KoolookTimelineEditor (k_timeline_editor.py) — plus the transcribe_audio_timeline.py CLI and its test. The audio-transcript to Director-timing job now lives inside the fork via the Director's audio_transcript_json input, so the standalone nodes are redundant. Also drops the orphaned [audio]/faster-whisper extra and updates packaging, dev-sync, web, and docs references.

Harden the node registry against the #183 failure: __init__.py now imports each node group independently and installs the /koolook/presets/* routes regardless of node-import results, so one missing or broken module degrades to 'that node absent' instead of zeroing every node and 404'ing the sidebar disk routes. A new test keeps every root k_*.py listed in dev-sync's RUNTIME_PATHS.

Closes #198.

* fix(nodes): ship loader gates via dev-sync-audio; generalize RUNTIME_PATHS guard (#198)

Address the K-Flame review on #199:

MEDIUM — the #198 refactor made koolook_versioning.py a single registration gate, but dev-sync-audio shipped the new __init__.py without it (and the k_*.py-glob guard test couldn't see it). Add koolook_versioning.py AND koolook_install_guard.py (whose absolute-import fallback raises uncaught) to AUDIO_PATHS so a scoped sync can never leave the loader pointing at a module the target lacks.

Generalize the guard test: parse __init__.py's actual load-time import targets (relative imports + _merge_node_group calls) and assert each is in RUNTIME_PATHS, instead of globbing k_*.py which missed the non-k_ gates. Add an AUDIO_PATHS gate-coverage test.

LOW — CHANGELOG now records the [audio]/faster-whisper + transcribe_audio_timeline.py removal as an external-contract break.
