gig: the set that logged itself, and the 17m44s before REC

Reconstruct 2026-09-24 from four independent lenses: gig-log eval, the
lcxl3-driver journal, gig-log focus, and full-resolution per-second levels
off the eleven Ardour stems. Eval and the surface journal agree to the
second on all fifteen boundaries, so nothing here is a statistical guess
the way CosmicFest's recovery had to be.

What the numbers say: 94 minutes, all fourteen planned tracks in order plus
sunny_side_up sixth, five xruns, zero throttle events. REC landed 17m44s
into the set, so salut_nu and love_first have no audio at all. Orbit 08 was
never record-armed and the control map lists it in every track. Neither
MIDI recorder captured a single control move.

+
+## Cap (what & why)
+CosmicFest-26 had to be recovered from one phone recording by three statistical
+lenses, and six of eighteen rows came back `unresolved`. Thirteen months of
+instrumentation later, Thu 24 asked the same question — *what did I actually
+play, and what got recorded* — and this time the rig already knew.
+
+## Manœuvre (how)
+Four lenses, none trusted alone. gig-log's `eval` (a real ctrl+enter reached
+GHCi) and the `lcxl3-driver` journal's `track ->` lines agreed **to the second**
+on all 15 boundaries, so the timeline needed no fusion verdict at all — two
+independent witnesses saying the same thing. The Ardour stems were then only
+*measured* inside those windows, never used to guess a name.
+
+One trap on the way: the first level pass read 4096 of every 48000 frames and
+reported most orbits at 0% active. That was the window landing between hits, not
+silence. Reading every sample of a 19 GB take costs 28 seconds. Decimation on
+percussive material is not an optimisation, it is a wrong answer.
+
+## Prise (findings / artifacts)
+- `armada/tide-table/build_gig_reconstruction.py` — re-runnable, four lenses in.
+- `take103_2026-09-24_recovered_set.md` + `.json` — the set, per-orbit levels.
+- **Set: 18:09:57 → 19:44:06, 94 min, 15 tracks.** All 14 planned, in order,
+  plus `sunny_side_up` inserted 6th — the encore candidate the setlist had
+  deliberately parked.
+- **5 xruns in 94 minutes. 0 throttle events.** The session's other 1177 belong
+  to soundcheck and the two laptop-sink nodes nobody cut. Four earlier sessions
+  logged 5172 / 4852 / 1114 / 987 Ardour xruns; the thread demotion holds.
+- **REC at 18:27:41 — 17m44s late.** `salut_nu` and `love_first` exist in no
+  audio; `piment_bresilien` starts 3:10 in. 81% of the set on disk.
+- **Orbit 08 was never armed** (`rec-enable value="0"`, alone among 12), and the
+  control map lists it in all 15 tracks. No file was created — an absent stem,
+  not a silent one.
+- **No MIDI from either recorder.** gig-log bound seq port `133:0` at 00:59 and
+  never rebound; Ardour's `Keys` wrote 24 files of 26 bytes each.
+
+## Sel (the shareable learning)
+**The lens that saved the night was not built for it.** gig-log has a MIDI lens,
+a recording lens, an eval lens, a thermal lens — and the reconstruction stands on
+the *LED driver's log lines*, written to explain surface repaints. Meanwhile the
+purpose-built MIDI lens had been dead since the night before and the purpose-built
+OSC recording lens was wrong for the entire 76 minutes (`conflict: true` from the
+first record to the last: Ardour's own transport feedback never once said
+"recording" while it was recording).
+
+Redundancy is not three copies of the good instrument. It is four instruments
+that fail differently.
+
+Corollary, learned the same morning: **the session file no longer holds the mix
+you played.** Nine of twelve faders read −∞ in `Tidal Live.ardour`, saved at
+19:44:41, twenty-six seconds after a surface `lap reset` zeroed the board. The
+stems prove those faders were up — orbit 04 sits at a −17 dBFS median and is the
+loudest orbit in 13 of 15 tracks. Audit the artifact, not the config.
+
+## Hameçon (hook)
+"I forgot to hit record." Ninety-four minutes later the laptop could still name
+every track he played, to the second, from a log written by the thing that paints
+the LEDs.
+
+## Sillage (what it unlocks)
+- Mastering can start: 11 stems, 76m19s, t0 = 18:27:41.201, per-orbit levels done.
+- Peaks over 0 dBFS on 13 of 15 tracks (worst +7.7) — the limiter was working.
+  His ear decides whether that is the sound.
+- A REC reminder is now buildable **and** the lens it must not use is identified.
+- Two open holes with names: orbit 08's arm, and gig-log's MIDI rebind.

+"""Reconstruct a performed set from the rig's own logs plus the Ardour stems.
+
+WHY THIS EXISTS
+CosmicFest-26 had to be recovered from a single phone recording by three
+statistical lenses, and six of eighteen rows came back `unresolved`
+(`cosmicfest26_recovered_tracklist.md`). From 2026-09-24 the rig logs enough
+that a set does not need guessing at all: this fuses four lenses that each
+know something the others cannot, and only *measures* the audio — it never
+uses audio to guess a name.
+
+  focus    gig-log `track`  — which .tidal was ON SCREEN. #148: looking at a
+           file is not playing it, so this is never a boundary on its own.
+  eval     gig-log `eval`   — a real ctrl+enter reached GHCi, with the dN
+           streams the block defined. This is the honest "the pattern changed".
+  surface  lcxl3-driver journal `track ->` — the control map that got painted,
+           carrying the per-track orbit list: what the INSTRUMENT believed the
+           track uses. Independent of gig-log; it survived the gig where
+           gig-log's MIDI lens did not (it had bound port 133:0 at 00:59 and
+           never rebound, so `cc` is empty for the whole set).
+  stems    full-resolution 1 s RMS/peak per orbit from the Ardour take. Ground
+           truth for what actually reached the DAW.
+
+Boundaries come from surface+eval (they agree to the second). Stems are then
+measured INSIDE those windows.
+
+TWO READINGS THAT ARE NOT ERRORS
+  * an orbit MAPPED BUT QUIET — a knob existed, the orbit stayed under the
+    floor. Same reading as an unresolved sample name: normal, never an error.
+  * an orbit HEARD OFF-MAP — it played with no knob on the surface. Can also be
+    a previous pattern still running, so it is reported, not interpreted.
+
+DECIMATION IS A TRAP HERE. The first pass read 4096 of every 48000 frames and
+the window kept landing between hits, so most orbits looked 0% active. Every
+level number below comes from every sample; the full pass costs ~30 s for a
+90-minute 11-orbit take, which is cheaper than being wrong.

+## 2026-09-24 — the AI ENGINEER set (Take103)
+
+**"boom, was a good live!"** and **"overall great gig bro"** — the whole-set
+verdict, unprompted, the morning after. First unqualified positive on a full
+two-hour slot. Worth holding against the measurements: 5 xruns in 94 minutes,
+zero throttle events, all 14 planned tracks in the planned order. The night the
+rig stopped being the subject.
+
+**"the midiviz had great success"** — audience reaction to the MIDI lens, not his
+own. Third independent signal that the *visual is part of the instrument*,
+after "the midi mon is beautiful" and the `salut_nu`-has-no-backdrop complaint.
+The taste is consistent and it is not about his comfort: he wants the visual
+layer treated as a deliverable of the performance, because the room responds to
+it. Note the irony worth telling: the surface the audience loved is the one whose
+own log captured nothing — gig-log's `cc` stream is empty for the entire set.
+
+**"i had forgotten to REC at first (we can discuss how to make that reminded!)"**
+— measured: REC landed at 18:27:41, the set started 18:09:57, so **17m44s** and
+two whole tracks (`salut_nu`, `love_first`) exist in no recording. He raised it
+himself before being told, and asked for a reminder rather than a fix. Pacing
+signal: the miss is at the *start* of the set, where attention is on the room and
+the first pattern, not on the DAW.
+
+**He played `sunny_side_up` 6th, off the setlist.** `setlist_thu24.txt`
+deliberately parked it as the encore candidate ("the most-played thing in the
+catalog, and it is NOT in the 14"). It went in at 18:42:41, right after
+`bain_electrique`, the set's fastest. Not a mistake to log — a live decision, and
+the only deviation from the written order in 94 minutes. Ask him what it was for:
+a lift after the 128 BPM, or a reach for something safe?
+
+**`rose_rouge` ran 11m34s**, nearly double the set's median track. The closer
+took its time. Consistent with the "closes on the slowest" design note.

+# Take103 — 2026-09-24, the set as it actually happened
+
+Reconstructed from the rig's own logs plus the Ardour stems, by
+`build_gig_reconstruction.py`. Re-runnable:
+
+    armada/tide-table/build_gig_reconstruction.py \
+      --log ~/.local/share/parvagues/gig-log/gig-20260924-005926.jsonl \

+Audio identity is **Take103 + 2026-09-24**. Gig metadata (venue, set title,
+poster, lineup) is not in this file and was not invented: there is no entry under
+`~/Work/Perso/www/content/lives/2026/` for this date. "AI ENGINEER" is the label
+in `backlog.md`; the play order is `armada/setlist_thu24.txt`.
+
+Unlike CosmicFest-26, nothing here is a statistical guess. Four lenses, each
+independent, and the audio is only ever *measured* — never used to name a track.
+
+| lens | what it knows | independent of |
+|---|---|---|
+| **surface** | `lcxl3-driver` journal `track ->`: the control map painted, with its per-track orbit list | gig-log entirely — separate process, separate journal |
+| **eval** | gig-log `eval`: a real ctrl+enter reached GHCi, and which `dN` the block defined | the surface |
+| **focus** | gig-log `track`: which `.tidal` was on screen. #148 — looking is not playing, never a boundary alone | — |
+| **stems** | full-resolution 1 s RMS/peak per orbit, every sample read | all of the above; it is bytes on disk |
+
+Surface and eval agree to the second on all 15 boundaries, so the timeline below
+is not a fusion verdict — it is two witnesses saying the same thing.

+
+Per-orbit `active_pct`, median and max RMS, and peak for every window are in
+`take103_2026-09-24_set.json`.
+
+Two readings in that table are **not errors**. *quiet* means a knob existed and
+the orbit stayed under the floor — the same reading as an unresolved sample name.
+*off-map* means an orbit sounded with no knob painted for it, which can equally be
+a previous pattern still running; `piment_bresilien`'s orbit 12 arrives with
+`love_first` still in the room, and is reported, not interpreted.
+
+## What the recording is missing, and why
+
+**1. The head: 17m44s.** REC was pressed at **18:27:41**, and the files lens
+caught bytes landing at 18:27:47. The set had started at 18:09:57. So
+`salut_nu` (9:21) and `love_first` (5:13) exist in no audio at all, and
+`piment_bresilien` is captured from 3:10 in. This is the one PLN already knew
+about; the two numbers he did not have are *when* and *how much*.
+
+**2. Orbit 08, the whole night.** `Tidal 08` in
+`../Ardour/Tidal Live/Tidal Live.ardour` carries
+`<Controllable name="rec-enable" … value="0"/>`. Every other Tidal route is
+`value="1"`. It was never armed, so no `Take103_Tidal 08` file was ever created —
+not a silent stem, an absent one.
+
+That costs something in every single track: the surface lens lists orbit 8 in the
+control map of **all 15**. `d8` is `xfade 8 . (|< orbit 7)` (`BootTidal.hs:222`),
+Ardour's `Tidal 08` is that orbit's stem, and the gig-log `eval` stream lists
+`d8` in every evaluated block of the night. Whatever it was carrying per track is
+not recoverable from this take — and cannot be measured, because the Master bus
+was not recorded either, so there is no reference to subtract the 11 stems from.
+
+**3. No MIDI, from either recorder.** gig-log's `cc` stream has 145 records, all
+between 00:59 and 01:01 the night *before*: it bound sequencer port `133:0` at
+startup and never rebound after the board was replugged. That is the known bug
+already written down in `TODO_GIG.md` ("gig-log loses its MIDI address and never
+looks for it again"). Ardour's `Keys` track wrote `Take104_Keys-1.mid` and
+23 others at 26 bytes each — empty files. So **not one fader move or knob turn
+from the performance was captured as MIDI.**
+
+What survived instead is the `lcxl3-driver` journal: 89 lines across the gig,
+every track load with its orbit list, its control count, its lap reset. That is
+what made this reconstruction possible, and it is the lens nobody designed for
+the job.
+
+## The rig, measured
+
+From gig-log, 18:09:57 → 19:44:06, cumulative counters differenced across the
+window (the raw fields are totals; a sum of them is meaningless):
+
+```
+samples          5650 ticks over a 5650 s window — gig-log missed nothing
+xruns            5        1 SuperCollider · 3 UMC input · 1 laptop sink
+throttle         0 / 0    core / package, zero events for 94 minutes
+package temp     66–77 °C, median 70
+fan              median 2950, max 3168 rpm
+cpu              median 18% average, hottest core median 49% / max 92%
+scsynth          20.1% cpu median (max 42.8), RSS pinned at 5325 MB start to end
+sclang           2.0% cpu median, RSS pinned at 324 MB
+ArdourGUI        30.8% median (max 141), RSS 585 → 679 MB
+pulsar           108% median (max 265), RSS 1332 → 1482 MB, peak 1685
+```
+
+**Five xruns in ninety-four minutes** is the number of the night. The session's
+full 1182 belong to soundcheck and to the two `sof_sdw` laptop-sink nodes
+(466 + 464) — the laptop speakers `TODO_GIG` step 4 said to cut and whose
+checkbox stayed unticked. Ardour itself: 60 for the whole session, and the audio
+path took 5 during the actual set. The `parvagues-protect` thread demotion from
+the 22nd holds up under load: four earlier sessions logged 5172 / 4852 / 1114 /
+987 Ardour xruns.
+
+Two things the log says happened and memory would not:
+
+* **ArdourGUI was absent for 349 s of the window** — up at 17:12:45, gone at
+  17:21:00, back at 17:21:06. Both during soundcheck, both before the set.
+* **pulsar disappeared at 19:44:22**, sixteen seconds after REC stopped. Not
+  during the music.
+* **gig-log itself was killed**, not stopped: no `end` record.
+
+## Two instrument bugs this take exposes
+
+**The OSC recording lens was wrong all night.** The 18:27:47 `rec` record is
+`"conflict": true` — the files lens saw bytes landing while OSC reported
+`arm:false roll:false`. It stayed that way for the entire 76 minutes and only
+agreed at the stop. Ardour's own transport feedback never once said "recording"
+while it was recording. Anything built on that signal — a REC reminder above all
+— would have fired continuously through a perfectly good take.
+
+**The saved session no longer holds the gig's mix.** `Tidal Live.ardour` was
+written at 19:44:41 and has `Tidal 02, 03, 04, 05, 06, 07, 08, 10, 12` at
+`gaincontrol` = 0 → −∞ dB. The stems prove those faders were up while playing:
+orbit 04 alone sits at a −17 dBFS median and is the loudest orbit in 13 of the
+15 tracks. Between the last note and the save, the LCXL logged two `lap reset`
+lines (19:44:15, 19:44:16) and `surface-state.json` went to all-zero. So the
+faders on disk are the post-gig surface state, not the performance — do not read
+that file as a mix reference. (`TODO_GIG` step 6, "Master fader up with the
+mouse. Then Ctrl+S", was never checked off either.)
+
+## For the mastering pass
+
+* **Source of truth is 11 stems, 76m19s, starting 18:27:41.201.** The take is
+  plain RIFF/WAVE float32 — Ardour wrote no `bext` chunk, so there is no BWF
+  origination timestamp and the wall clock comes from `mtime − duration`,
+  corroborated within 6 s by the files lens at 18:27:47.
+* **Peaks are over 0 dBFS on 13 of 15 tracks**, worst `take_5_drops` at +7.7 and
+  `cafe_bouillant` at +7.6. Float, so nothing clipped on disk; but the Master
+  bus ran at −5.0 dB into an ACE Compressor and an LSP Limiter, and those numbers
+  say the limiter was doing real work. Whether that is the sound wanted is PLN's
+  ear to decide — there is no Master recording to measure it against.
+* **Orbit 04 is the spine**: loudest orbit in 13 of 15 tracks, 89.8% active
+  across the whole take, median −17 dBFS. Its role per track still has to be
+  measured, never read off a name.
+* **`rose_rouge` ran 11m34s**, by far the longest — the set closed slow and long,
+  as designed.
