fix(bounds): a skipped seam carried PLN's best information, and the exporter threw it away 

PLN: "wait you dont get the notes when i skip? DANG they have lots of info."

The exporter emitted skipped boundaries as bare integers:

    skipped: Object.entries(calls).filter(([, c]) => c.t === null).map(([k]) => Number(k))

so eight CosmicFest seams exported as `[2,4,9,10,15,16,17,18]` while the notes he
had typed into every one of them vanished. And a skip is not an absence of
judgement — it is usually a judgement that the SEAM is wrong, which is more
informative than confirming a cut time. What was lost included "theres no
blue_gold in this set, we're hearing do_it_right throughout", "there was no
gimme_acid in this performance", "theres no funk->piment transition! in this set
i playd piment once, then funk", and "it could be called Outro Dub Siren".

The notes were never actually gone: the textarea writes `{t: t ?? null, comment}`,
so a skipped call keeps its comment in state and in localStorage. Emitting
`skipped` as {id: {source, note}} therefore recovers notes ALREADY STORED, not
only future ones — PLN re-exports and gets them back verbatim. Verified the built
bundle carries it, after first mis-verifying: `grep -c` counts LINES and a
minified bundle is one line, so the honest count is 2 occurrences, not 1.

With his corrections the true set is 14 tracks, written to
judge_specs/cosmicfest-2026_setlist_ear.json as ground truth.

Scored against it, the three-lens pipeline named 12 of 14 tracks correctly and
labelled 81% of the 63 minutes, 85% of the labelled overlap correct. bombe_dj,
rose_rouge, ouais_je_funk, punkachien and livecode_parade landed at 100%.

The two failures are the same failure. `perfect` was called gimme_acid and the
improvised outro was called REVOLUTION, and both are reference-bound: crossmatch
can only choose among tracks it holds a prior render of, so audio from a track it
has never heard gets assigned to the nearest thing it has. All five "ghosts" —
blue_gold, desire, gimme_acid, quand_on_decolle, REVOLUTION — are that same
mechanism. It is a structural limit, and the fix is one render per track, not a
better threshold.

Also banks his ear-feedback in performance_notes.md, including two things no
analysis could have produced: a loud blip in the 2.9 s between two tracks (a
defect belonging to NEITHER, which the boundary tool currently has no way to
express), and why desire was dropped — "Clearly didnt play desire i was not found
of that closing at opal".

Both were his second listen changing the answer, which is the argument for
keeping the audition loop cheap: neither correction cost more than a re-render.
## CosmicFest 2026-08-23 — ear pass over the room recording (2026-08-29)
PLN auditioned all 18 machine-proposed seams in the boundary lab, against a
handheld stage-mic capture (`ZOOM0067.MP3`, 62:59). His verdict on the recording
itself, before any of this: *"imo we have a bad rec cause the whole soundsystem
had effects and at some points ppl messed with it lol"*.
**A mix note, not a boundary note.** At the rose_rouge entry: *"at 22:42 its end
of reose_rouge, theres a loud blip noise, at 22:44.9 its the start of rose
rouge, could we cut noise and blend better?"* So a transition can carry a
**defect** that is neither of the two tracks — a blip in the 2.9 s between them.
The boundary tool asks "where does the next track start" and has no way to say
"there is garbage here"; a `noise` mark would let him flag it in place.
**A track that only exists live.** The final 103 s: *"thissegment is pure
dubsiren noise and fun ahahah it could be called 'Outro Dub Siren' ahah"*. The
machine labelled it REVOLUTION, which is the best any reference-based lens could
do — there is no prior render of an improvised outro. Worth catalog-ing under its
own name if the set is ever released.
**A closing he changed his mind about, across gigs.** *"I closed on vague de
crime i think i recall now! Clearly didnt play desire i was not found of that
closing at opal :')"* — the OPAL-26 ending was not to his taste, so he dropped it
at CosmicFest. That is a set-order preference the backlog does not record, and it
explains a machine "ghost": `desire` was proposed at 60:15 purely because a prior
render of it exists.
**Two tracks he did not play at all**, both of which the machine proposed:
`blue_gold` (*"theres no blue_gold in this set, we're hearing do_it_right
throughout"*) and `gimme_acid` (*"there was no gimme_acid in this performance"* —
it was **perfect**). Both were reference-driven false positives: crossmatch can
only choose among tracks it holds a render of, so an absent track's audio gets
assigned to the nearest available one.
**And a structural correction worth remembering for set prep:** *"BTW theres no
funk->piment transition! in this set i playd piment once, then funk, then next"*.
The machine had piment_bresilien and ouais_je_funk alternating in 45-80 s slices,
which was a median-filter artifact, not a performance. A real set alternating two
tracks four times would be unusual; treat that pattern as suspicious by default.
