Where fallow flagged something of mine (a complexity +threshold, twice) I fixed it rather than suppressing it. + +--- + +## 2. Two invariants this session established the hard way + +These are the two things most likely to be re-broken by someone who has not read +this document. + +### 2.1 The id-space boundary + +The timeline and the property panel identify elements **differently**: + +- **Timeline store key**: `sourceFile#domId`, e.g. `index.html#vo-2` (`element.key`) +- **Panel / DOM / runtime**: the bare dom id, e.g. `vo-2` (`element.id`) + +`runtimeAudioId()` in `packages/studio/src/player/lib/timelineElementHelpers.ts` +is the conversion. Handing a composite key to something that expects a bare id +fails **silently** — no error, the feature just never matches. This bit the +`setTiming` work before (see the memory note `project_settiming_hfid_space_fix`) +and bit the reveal feature in this session (§4.6). + +### 2.2 A carve's lanes belong to the carve + +A voiceover carve compiles to several `fromCarve: true` nodes in the chain and +writes an envelope per node. `withoutCarveLanes` **replaces every one of them** +on each re-analysis. Consequences: + +- A drag on such a lane is silently discarded next analysis → they are shown + **read-only**, not hidden (§4.3 — this was got wrong first). +- A per-lane remove button on one would appear broken → withheld. Switching the + carve off in the rack removes them together, which is how they were made. +- The rack's `handBuilt` list **filters carve nodes out**, so `openNode` cannot + address one. Anything mapping a lane to a rack row must resolve which _surface_ + owns it (§4.6). + +--- + +## 3. What the user asked for, in order + +Every item below was a separate instruction. Worth reading as a whole because +several later items reversed earlier ones. + +1. Remove the "Holds…" line from the group header → deleted the whole bus strip. +2. Don't show the automation-lane toggle when a row automates nothing. +3. "I automated a group effect property but the automation icon didn't appear." +4. "I ended up with a voiceover track in a voiceover group, carving against that + group. How did this happen?" → root-caused, three bugs. +5. "Why was a voiceover track carved at all? Only music and sfx should be." → + a fourth, deeper bug. +6. Multi-select of audio clips offers layout grouping, which doesn't apply. +7. …and offers "Hide all", which shouldn't be possible for audio. +8. Make automation lanes always visible, drop the toggle. +9. **Reversed #8** — "I didn't realise it was an existing pattern; put the + toggle back." +10. Don't change the header layout/icon when a track has automation. +11. "The layout is messed up when automations are active." (twice — I fixed the + wrong thing first) +12. Music bed has a carve but shows no automation and no toggle. +13. Put the automation toggle and FX button on one line with the title, + right-aligned; clip count left-aligned by the title. +14. Use the property panel's larger caret for group headers. +15. Same one-line layout for group headers. +16. Wrap gutter names instead of truncating with tooltips. +17. Render failed with `Cannot find module …/renderOrchestrator.js`. +18. Restart the studio. +19. Clicking an automation lane header should open the rack on that effect and + scroll to it. +20. Is the skill updated to use the bus? → it was not; wrote it. + +--- + +## 4. The substantive findings + +### 4.1 Four carve bugs (commit `5d8fbf5d3`) + +The user's voiceover-carving-its-own-group situation had **four** causes, each +sufficient alone. All four were mine or pre-existing, none were user error. + +1. **No bed-eligibility rule at all.** `couldBeCarveSource()` had existed in + `packages/core/src/audioCarve.ts` since it was written, with a doc comment + saying "music and sfx are out" — and **was called from nowhere**. Exported, + tested, dead. Nothing ever asked the near-end question: _can this track be + the bed?_ Added `couldBeCarveBed()` and wired it in. + + **Still true at the tip:** `couldBeCarveSource` remains uncalled outside + core (the only studio hit is a doc comment in `useFxCarveGrouping.ts:180`). + The _source_-side filtering is done inline by `classifyAudioName` checks in + `useFxCarve.ts` instead, so the two now say the same thing in two places. + Worth collapsing — see §8. + +2. **Offering ≠ applying.** A bed with exactly one candidate voice carves itself + unasked. Right for `music-bed`; wrong for `a1`. Added `isNamedCarveBed()` so + self-application needs a name that positively reads as a bed. The picker stays + looser — the same split the source side already made between `sourceOptions` + and `autoSourceIds`. +3. **A member was offered its own group.** The candidate scan excluded exactly + one element (the bed). Its _siblings_ survived and rolled up into the group + the bed belongs to — which came back as a candidate and, being the only one, + was auto-applied. +4. **A group was offered itself.** A group bed's id matches no `
