Run and poke the live game

How to touch the live process. Observation is PERF.md.

set -a; . ./.env; set +a          # IW4L_GAMES; DISPLAY=:0 if the session has none
make map mp_boneyard CMDS='spawn assault; wait 2s; quit'
cargo run --profile play -p launcher -- map iw5:mp_overwatch --cmds '…'

make passes no foreign flags through: in the Makefile it is CMDS, on the binary --cmds. The colon is a GNU make pattern, so make map iw5:… fails — write make map ZONE=iw5:mp_overwatch or use cargo run. Recipes: make scenario, chaos, bench-demo, bench-live, lifecycle-* (*_CMDS in the Makefile). Live recipes use [profile.play]; for LTO, PROFILE=release.

Controls are frozen until the match starts. sim::step allows movement only in MatchPhase::Playing; hold +attack, +forward and move do nothing before then. You wait out PLAYER_WAIT_MS 15 s + MATCH_START_MS 5 s (crates/gamemode_iw4/src/prematch.rs) — bots (≥ 2 live players) cut the first timer short, a single-player script waits the full 20 s. The verb is shorter: wait world; spawn assault; force_match_start; wait 1s; …, and a script involving firing, hits or decals lies with a zero without it.

Sync by default. Ritual waits are unnecessary: a command holds the FIFO until its own fact — map/demo/play until the swap plus GPU-ready WorldScene::spawned, spawn until AppScreen::InGame, move/look/tp until a matching presented pose, force_match_start until Playing, disconnect until the hold is torn down. wait Ns remains, for pacing and observation windows. The & suffix is a loud refusal to wait (map mp_rust &), ! jumps the queue (in bash write disconnect !, or history expansion bites). The 120 s gate timeout aborts the rest with an echo; parsing is crates/console/src/. Hand-typed dump/clip/screenshot pass through any wait while preserving the queue, which inside --cmds takes an explicit !.

Verbs and traps

map spawn class give attach name kill damage move tp look nudge press hold release bind bot wait mark record stoprecord clip demo dump screenshot ui disconnect quit plus the debug force_match_start / showpos. bot is add | hold | tp | give | fire; dump [name] writes the current snapshot into dumps/. clip writes the last available 45 s into clips/<ULID>/ (demo + dump) on host and clients — the host records authority, a client the snapshots it received plus its own presented state; demo LATEST plays it back.

• ADS is hold +speed_throw, not +speed;
• bolt action (fire_type=1): hold +attack is one shot, and a full magazine will not reload itself (press +attack ×N, then press +reload);
• look without LookState only writes ps.viewangles — no aiming;
• give takes a namespace: give t5:weapon/psg1_acog, give iw5:weapon/msr.
