+### Phase 4 — The role ladder (design §6; future, do not start)
+Glassie, bartender, DJ roles + roster board. Not scoped yet — but it imposes ONE
+rule on every earlier phase: **the simulation is role-agnostic.** Crowd sim, patron
+state, meters, and incidents must never assume the player is security — the player
+is just an entity with a verb-set reading shared state. If you're about to hard-code
+"the player" into a sim system (e.g. "patrons only get cut off by the player"),
+model it as an actor capability instead (NPC staff already need this — Kayden works
+the door while you're on the floor). The DJ role will drive the TechnoEngine
+directly, so LANE-JUICE keeps track parameters (BPM, layer intensities) externally
+settable rather than hard-coded.

-Venues as levels, nights as rounds (Thu → Fri → Sat per venue):
+**Structural principle: the venue is ONE simulation; a role is a lens + verb-set
+over it.** Patrons are role-agnostic data wandering the crowd sim; each role is a
+scene that reads the same state with different permissions. The career ladder
+doubles as the tutorial — each role teaches one system before the endgame role
+demands them all. NPC staff work whichever roles you aren't (competence varies —
+see Kayden).

+| Role | Verbs | Teaches | Signature tension |
+|---|---|---|---|
+| **Glassie** (entry) | Collect glasses (hand-stack grows: taller = clears faster, wobbles more; drop = smash + mop duty), mop spills before slips, restock runs through the crowd, find lost phones | Floor navigation, drunk-tells by pure observation | ZERO authority. You see the Maggot but can only radio it in — and watch who responds |
+| **Bartender** | Order queue (orders get slurred/ambiguous with patron drunkenness), pour minigame (jigger = safe, free-pour = fast/risky), tips via speed + banter picks, drink-watch (intervene on the glass-hoverer) | Intoxication rules from the server's side | RSA: you legally CANNOT serve a Maggot — the cut-off with them begging across the bar, Heat if the inspector's watching |
+| **Doorgirl** | The Door phase (§3.1): IDs, dress code, guest list, rope theatre | Inspection & social judgment | The whole §3.1 tension set |
+| **Bouncer** | The Floor phase (§3.2): patrol, ejections, stalls, pat-downs | Enforcement & positioning | The whole §3.2 tension set |
+| **DJ** (unlock) | Ride the crowd's Energy curve with track picks (tracks = parameter sets on the synth engine — gameplay drives the actual audio), beatmatch transitions (align two beat bars, cut on the one), field booth requests | Reading the room | Request verbs: the dismissive headphone-lift, the nod-then-never-play, the hard no. Denying: +Vibe (purists), +Aggro (requester's table) |
+| **Head of Security** (endgame) | §3.1 + §3.2 interleaved, PLUS radio command of NPC staff in every other role | Everything at once | You used to speak into the radio; now you're the voice on the other end |
+
+**Roster board** frames progression: pick shifts from a weekly roster
+(role × venue = level select), wages differ by role, story beats attach to roles.

+Venues as difficulty tiers, nights as rounds (Thu → Fri → Sat per venue):

 Roguelite-lite structure: fail a night → retry the night; 3 Heat strikes → run over.
 Seeded runs for shareability ("seed VALLEY-4207 is brutal").

+one night, each player a role. Architecture shouldn't preclude it; nothing should
+be built for it.)*

 ## 7. Scope guardrails

+- v0.1 = ONE venue, Door phase only (the doorgirl shift), 3 nights, placeholder
+  paper-doll art. Ship it.
 - v0.2 = Floor phase + door/floor interleave + audio engine.
 - v0.3 = progression, regulars' memory, incident report, inspector.
 - v0.4 = content pass (archetypes, scripted encounters), real pixel art, boss venue.
+- v0.5+ = the role ladder (§6): glassie → bartender → DJ, roster board. Roles are
+  post-core-game content — but every earlier phase must keep the sim role-agnostic
+  (no system may assume the player is security).
 - Cut before slipping: fight mini-game, budgie, venue 3. Never cut: the clicker,
