Desk edit from tonight's rehearsal. `|- note 36` -> `|- note 12` on acidOto3092,
and the mask(16,32)+ply gate commented out so d7 runs the arp clean.

PLN: "deliberate killed tail was just a agent log or srth, capture that removed
as learning, nut then let me clean that backlog indeed was gboing tedious."

The tail is cleared and the new AI ENGINEER candidate section stands. But the
543 lines were not a log: they were two sessions of rig notes from 6-7
September, and six items in them were still open. Losing them to a backlog
cleanup is the quiet kind of loss — nobody misses a note they have forgotten
writing.

So the whole block is archived verbatim in docs/, with the open items hoisted
to the top of it where they can be read without scrolling. The one that
matters: `sudo tools/install-protect.sh` was never run, so the OOM-protection
daemon has never actually protected anything — it reported ok only because
scsynth and sclang already sat at the target value, and no write was attempted.

The remap commit carried counts. Counts do not help at the desk: a knob that
moved from C5 to B4 is a knob that does nothing when you reach for it. The
tracker now holds the was/now table for every one of the 24 moves, because
PLN is rehearsing jeudrill and rose_rouge tonight and both of them moved.

Also recorded: techno_orage's ^58 firing across d5 and d6, the corpus-wide
154-file job that is explicitly NOT for tonight, the 114 duplicate FIXME lines
left behind by the old non-idempotent tool, and the fact that "the set" still
resolves to the Opal list through backlog.md while Thursday's arc lives only
in armada/setlist_thu24.txt — a default nobody should trust this week.

Two fixes in the tool itself:

  * the FIXME dedupe was a snapshot taken before the insert loop, so one run
    could still stack two identical notes when an orbit is split across two
    blocks. It now learns as it writes.
  * the docstring still promised that buttons were "Phase 2, after the gig".
    They were folded in when #94 shipped, and the tool has been moving BT/BL
    cells ever since. A docstring that defers work the code already does is
    the one place a reader can learn the wrong scope.

The #94 remap was run against a setlist, not the catalog, so conformance was
never a property of a track — it was a property of having been on that list.
Two days of desk edits then pushed listed tracks back out: swapping jeudrill's
d9 and d10 bodies moved the orbits but not their knobs, so d4's effect was
sitting in d5's column again.

Migrated, one simultaneous permutation per file, 24 moves across six tracks:

  jeudrill        6   the d9/d10 swap's knobs follow their orbits
  liquid_nite     4   the four PLN had not reached by hand
  rose_rouge      3
  techno_orage    9
  cyber_hump      1
  siberie_samuel  1

liquid_nite is the one that prompted this — PLN saw it in the catalog, wanted
it in the set, and found it half-migrated: he had walked the buttons down a
column by hand (^42 -> ^41, ^43 -> ^42) and stopped. The knobs are now on
their own columns too, and it evaluates clean.

VERIFIED, not assumed: re-plan reports 0 moves on all six; silent-eval
--seeded is OK on five. techno_orage still FAILS, on the same d2 that was
already silent before this commit — unchanged, and still PLN's call to fix or
cut. pvlint: 0 errors, 21 warnings, all pre-existing shapes (PV013 missing
family mutes, PV005 double declarations). One is worth reading: PV008 says
techno_orage's ^58 drives d5 AND d6, which is the overflow the tool annotated
rather than commented — a $-step cannot be commented out without breaking the
block's arity, so that button really does fire across two columns until gSel
folds it.

AND THE TOOL NO LONGER TALKS TO ITSELF. Every run stacked another
byte-identical FIXME paragraph above the same line: cafe_glace carried the
same note three times, and 90 files in the corpus carry 114 duplicate lines
between them. An overflow is a standing condition, not an event, so it earns
one note. The comment-out still runs on a repeat pass — if a line came back to
life it is firing across columns again whatever the note says — only the note
is deduplicated. Proven by applying twice and diffing: 15/13 both times.

Corpus-wide, 154 files still want 709 moves with zero clashes. Not tonight.

Everything here was already in the working tree — played, kept, never
committed. Written down now so the gig runs off the repo and not off one
laptop's dirty tree.

  siberie_samuel  NEW FILE, and it is in the Thursday candidate arc. It
                  existed only as an untracked file: nothing outside this
                  filesystem knew the track was real.
  liquid_nite     the buttons walked down a column by hand (^42 -> ^41,
                  ^43 -> ^42) and a long tail of commented-out orbits was
                  cut. The button axis is Phase 2 of the #94 remap, so this
                  is hand work ahead of the tool, not a conflict with it.
  jeudrill        d9 and d10 swapped bodies; the d9 crushbus commented out.
  you_my_sunshine cut 3 and the legato sweep off; room 0.14 -> 0.8, sz 0.9.
  techno_orage    back to the Children Holiday line, slow 4 on the notes,
                  cut 3 dropped.
  esperluette     the bassWarsaw d5 removed.
  sept1           resetCycles dropped from the top.
  piment_bresilien whitespace.

setlist_opal2026.txt loses its SOUNDCHECK section, so the pairwise walk in
orphan-orbits.py starts on the real opener. That file is a record of a past
gig, so the removal is visible here on purpose rather than folded into a
larger commit.

The sweep evaluated all 703 tracks on Sunday night and found 597 that compile
and emit. The picker still carried fourteen hand-written entries, so the page
said the library was fourteen deep — the measurement existed and the surface
that needed it did not have it.

gen_setbuilder_catalog.py turns the sweep into the page's data, joined against
two things the verdict alone does not tell you: how often the driver journal
saw the track loaded (what the hands know), and how many of its sample banks
the preload plan already warms (a cold bank is not a fault, it just hiccups on
the first bar). Sample names come from setlist_samples.py, never a fresh regex.

The sweep results now live in docs/ instead of a scratchpad that dies with the
session — an artifact nobody can compare against is the preload.scd story.

Ids are repo-relative paths, not stems. Sixteen stems collide across folders
(major_nostalgia in chill and techno, all four FFF tracks in two trees) and a
stem key merged each pair into one card, silently. Picks stored under the old
stem keys are migrated on load where the stem is unambiguous.

And the Thu-24 list is a candidate arc, not a locked set. It was exported from
the builder, not decided at the desk; rehearsal decides.

docs(tasks): the set is locked, the preload covers it, and the gate that would have undone both is fixed

gig-up runs check-preload --fix whenever the check fails, so a plan that was a
deliberate superset scored STALE and got silently narrowed — bass2 would have
been dropped on gig night and ete_a_mauerpark would have lazy-loaded mid-set.
Membership now uses comm -13/-23 (missing is a fault, extra is information),
counts join on shared banks, and --fix emits the union so it can never shrink.

Second hole, latent: under en_US.UTF-8 a whole-line sort orders 'bass2 5' before
'bass 4' while join compares field 1, so join dropped a pair (123 of 124 shared
banks) and 2>/dev/null ate its warning — a count check with a hole reports ok.
LC_ALL=C and sort -k1,1 on every set operation; join now equals comm -12.
Extras are also count-checked against disk: SuperDirt asserts the recorded count
at boot whether or not the bank is in the set.

Not sampled: every .tidal under live/ evaluated with silent-eval --seeded.
85 do not compile and 21 have a genuinely silent orbit; the failures are
diffuse helper/API drift (scope errors on g, jchord; Pattern String type
mismatches), not one rotten folder. Playable is still not gig-ready — the
play log remains the better signal for a set.

From PLN's Set Builder export, 120/120 min. All ten pass silent-eval seeded;
the set needs 46 banks, all present on disk. preload.scd (gitignored, generated)
regenerated as a superset — 125 banks, adding bass2 for ete_a_mauerpark.

The row existed but bare, and libjack.so.0 resolves to jackd2's — an unwrapped
qjackctl shows an empty jackd2 graph instead of PipeWire's. Same wrap as Ardour.

Three rig items and two of the three next moves closed while the page was being built;
SOUND now carries the measured Master reading instead of the wrong -inf claim.

Where Thursday stands on paper: rig, set, sound, stage, rehearsal, each with an honest
figure and the items only PLN can do, over a live countdown to doors.

check-mix against the running session: twelve orbit faders between +0.0 and +6.0 dB,
none muted, all routed to master. The overnight -inf reading does not hold. Master
-30.2 dB is the real finding, and with OSC off only PLN's eyes can confirm the live value.

A hard DJF swing froze the readout: the 20 Hz door dropped events without
parking one, and the 0.9 s re-arm then replayed the cached strings, so a
value the glass never caught was reprinted indefinitely — pinned at 127 the
'end stop' continue skipped the display entirely and 5.6kHz (value ~108)
stayed on screen for good. The re-arm now recomputes from self.values, so any
dropped event heals within 0.9 s whatever ate it; the door parks instead of
dropping; the flush takes the freshest value. Momentary family_mute lines
still replay — mutes_held() is transient state, not durable.

Cream ground, warm brown ink, sage for OK, amber for WARN, terracotta for the
played-recently badge. Screenshot-verified over HTTP at 1400px.

Fourteen candidates: the nine from the overnight sweep plus the five the driver journal
shows PLN actually played this week, each with its silent-eval verdict. Per-track minutes
against the 120-minute target, reorder, copy the paths out. One static file, no build,
renders offline, LAN-reachable for phone picking.

docs(tasks): Tue-22 gig state — the latency cut is not live, the CPU is capped, and the play log names the set

Three corrections from measurement: sclang predates the s.latency edit (still 0.2 in the
process), max_perf_pct is 55 so every audio number is suspect, and the driver journal shows
12 tracks actually played in 5 days — five of them outside the overnight sweep.

rel_delta caps one message at +-63 (7-bit offset-64); firmware acceleration
compresses a fast flick to 1-2 messages, so flick-to-max landed at ~125.
A saturated delta in the end-stop band (>=115 up / <=12 down) now snaps to
127/0 — slow turns never saturate, precise control untouched. Feel bands,
PLN vetoes at rehearsal.

The firmware's per-control value row never shows driver-integrated values
for relative encoders (stuck at 0 — probe H5 unresolved); PLN chose one
coherent fast overlay over 29 firmware-drawn fictions. Overlay-only mode
(promoted from --oled-overlay fallback to default) draws every knob on the
global 0x36 target with bring-up-after-write; --oled-native restores the
old firmware-drawn mode.

s.latency 0.1 (oLatency 0.1 on top = 0.2 total; the old padding defended
against watchdog-restart bursts, not latency). Regression check in-file:
journal late-count must stay 0, revert on any late. gig-up --bt-off/--bt-on:
a phone or BLE lamp churning wireplumber can kill the fold links — rfkill
the radio before doors.

Eye-in-the-loop probe (lcxl3-probe-display, 2026-09-21) falsified the
'a field write needs no re-summon' assumption: bare set_text on a visible
target (0x35 AND 0x36) never reaches the glass. Every text path now ends
in configure_display(target, 0x7F): touch overlay, 2s home tick, zero-anim.
Plus: ~10 Hz rate gate with latest-value-wins pending flush (H2 ceiling
untested — conservative), and the at-rest overlay re-arms every 0.9s
indefinitely so DJF state/zero stops self-destructing after 1.2s.

Overnight silent-eval sweep of 9 WIP set candidates: 7/9 can play with the
standard #55 seed; techno_orage d2 is a real silent orbit to debug; bass2 and
humps banks not warmed by preload.

docs(tasks): park the card-profile learnings — wireplumber 0.4 lua rules, DMIC guard, ardour sink follow

5 CC moves the buffer-clobber detector wanted (the gate went NO-GO over
it): the track was committed on the pre-remap grid, so its d3/d4/d7
buttons fired across columns into other orbits' controls. Mechanical
remap only; the ^44 step keeps its FIXME(#94) note.

The Bridge's RIG UP ran tools/gig-up.sh --converge, whose converge never
starts lcxl3-driver (boot policy manual), and whose LCXL checks grep the
v2 name 'Launch Control XL' — so a v3 board plugged in read as absent,
painted by nobody, and the gate still said GO. Meanwhile the desktop
launcher runs the ROOT gig-up.sh, a second launcher with the leds() the
gate lacks — two launchers, each owning half the surface story.

- launchers: Ardour launches under pw-jack like gig-up does (bare ardour
  starts its own jackd and splits the graph from scsynth)
- gig-up: 'LCXL present' matches LCXL3 too; 'LCXL LEDs' is
  generation-aware (LCXL3 -> lcxl3-driver, original -> lcxl-leds-watch)
- lcxl-path: follows the v3 path LCXL3 -> driver's 'ParVagues LCXL3'
  virtual port -> SC, falling back to the Midi Through road for v2

Every tray GIG UP click POSTed to the Bridge, which ran
'gig-up.sh --converge --quiet' — flags this script never parsed, so the
arg guard rejected it with 'unknown option' and exit 2, output swallowed
by the Bridge's capture. Net effect: Pulsar opened (PRE_APPS, before the
POST) and nothing else ever booted. The script and its caller had
drifted apart on paper only — this is the contract, written down.

The double click was the appindicator extension's, not ours: it reserves
double-click for SNI Activate (instant menu) and delays single-click by
400 ms, so a single click feels dead. Nothing to fix tray-side; documented
in the changelog.

- BRIDGE_QSS restyles the Qt-drawn popup on dark desktops: tonal surfaces,
  hairline borders, hover pill, magenta on the engaged radio; circles for
  radio groups, squares for boolean toggles. Contrast measured: body 14.7:1,
  disabled 6.4:1, radio ring 3.3:1 (bumped from 2.3:1 in review).
- stat rows and the thermal tooltip read in tabular digits.
- every user-visible string loses its em dash (colons, parens, middots);
  same pass on gearbox.py labels (shared with the web Bridge) and the
  launcher blurbs; unknown gearbox placeholder is now n/a, not a bare dash.
- mnemonics on the action rows (&Open Bridge, &GIG UP, &Restart SuperDirt,
  R&ig, &Start at login, Cut G&PU, &Quit); verified over DBusMenu that Qt
  exports them as underscores, so the shell-drawn twin gets them too.
  Literal ampersand does not survive the export, so the copy avoids it.

The GUI launcher started SuperDirt, Ardour and Pulsar as raw processes and
never touched the systemd --user layer, so a tray that exits 0 when the shell
takes its host away (perf-tray, Sep 14) or a user-closed MIDI lens (exit 78)
stayed dead: the only convergers were tools/gig-up.sh --converge, rig-doctor
and the Bridge watcher, and the Bridge was dead too. Three days of launches
"worked" with no tray and no lens.

ensure() now refuses to start a unit whose proof process already runs outside
it — which is what makes it safe for the launcher to call --ensure --apply
after scsynth is up instead of spawning a second SuperDirt through
parvagues-sc.service. --status agrees, so a launcher-started SuperDirt is no
longer a false problem row. gig-up.sh converges right after the ready-wait,
and honours the midiviz close-latch (the tray's MIDI Monitor button is the
way back within a session).

open_term() launched sclang directly, bypassing parvagues-sc.service and its
10-pipewire-jack.conf drop-in. With jack2 installed, ldconfig hands scsynth the
real libjack, it finds no server and starts jackd on hw:sofsoundwire, which
takes the card from PipeWire by D-Bus reservation. Meters move, nothing is
audible (raw jackd -dalsa bypasses ALSA UCM, so the SOF speaker route is never
enabled), and Bluetooth cannot work at all since jackd has no BT backend.

Also adds tools/parvagues.desktop so the ordered launcher is one Super-key away;
nothing had ever been installed in ~/.local/share/applications.

"i see the parvagues tray icon, but doesnt react when i click" — twice, with
the unit green both times. Three findings, in the order they mattered:

- The menu WAS exported and populated all along (19 rows over
  com.canonical.dbusmenu). What made it useless is the style: with
  QT_QPA_PLATFORMTHEME=qt5ct and no qt5ct config under the unit, Qt picks
  `qt5ct-style` with a bare #efefef palette — a 2009 grey box on a Yaru
  desktop. Now: Fusion, plus an explicit dark palette when the desktop asks
  for dark (GNOME's color-scheme is the one setting that knows).
- The tray host on GNOME is an EXTENSION, and it registers its
  StatusNotifierWatcher seconds after login. perf-tray printed "No system
  tray available", exited 1, and only Restart= saved it 3 s later. A slower
  login loses that race. Now it waits up to 120 s, polling on a QTimer
  (availability arrives over D-Bus, so the event loop has to be spinning).
- New check `perf-tray reachable`: unit active, item REGISTERED with the live
  pid (a stale item from an old pid looks identical on screen), and the menu
  populated over dbusmenu — the only one of the three that a click needs.
  Negative-tested against a stopped tray.

Also:
- `wireplumber churn` check: starts per hour, and who asked for them. The
  existing checks could only see the wreckage (a failed unit, a dummy sink);
  this sees the cause while audio still works. It FAILs on tonight's 48.
- The kwin midiviz-pin check asked KDE questions on a GNOME session, so it
  warned forever about a file that will never exist. Desktop-aware now: a
  check that cries wolf is one nobody reads on the day it is right.

The rig is multichannel by design: orbit k is the pair (out_{2k-1}, out_{2k}),
wired to its own Ardour track at a gig. Away from the stage that design means
d1 is the only orbit that can reach a sink — and on a freshly booted laptop
(2026-09-07) not even that: scsynth had NO links to any sink, so the whole box
was silent with every check green.

- tools/fold-orbits.py: fold all orbit pairs onto one stereo sink, summed at
  unity. Idempotent, and it VERIFIES — pw-link exits 0 for "File exists" and
  for a port that vanished mid-call, so its exit status proves nothing. The
  channel count is discovered from the graph (28 today, 12 in an older
  comment, 2 on stock SuperDirt), never assumed. Refuses while Ardour runs,
  which owns the mix and prunes SC->hardware links every 2 s.
- gig-up.sh --headphones: SuperDirt -> fold -> Pulsar. No Ardour, no fader
  restore; the fold becomes the readiness gate, because it IS the whole
  monitoring path.
- gig-preflight: `monitor path` check — stage (Ardour receiving on N tracks)
  or headphones (fold present), and it asks fold-orbits rather than
  re-deriving the port math.
- 18 tests, fixtures captured from the real graph: `pw-link -lo` marks links
  by INDENTATION only, so a grep of it fabricates relationships, and a source
  port printed with no indented child is the exact state this tool fixes.

Measured, not assumed: 14/14 orbits arrive at the sink (bd swept d1-d14, peak
per orbit), and the links survive 32 s of autoroute reconciling.

First production run of the failed-units check flipped the whole set-
readiness verdict on apport-autoreport.service — honest but wrong: the
rig runs entirely in user scope, and system-scope corpses (apport, snapd
chores) rarely gate a set. User scope stays a FAIL.
