The seeding moves from scene_probe into examples/support/ledgers.rs and trap_hunt reads it as FLY_TRAP_SEED_*, so both arms of a hunt can start inside the state the live session was in: row 57's pad was dealt by ledgers a restore starts empty, and a hunt from the bare checkpoint never meets it. The report gains refusals by macro and the longest run of one macro refused with the fly on one tile. scene_probe's own choice seed is FLY_PROBE_RNG now, so it does not read as one of the FLY_PROBE_SEED_* ledgers.

//! Loop detector: run macros mode from a checkpoint and name every window the fly spent going
|
|
//! nowhere.
|
|
//!
|
|
//! The Viridian stall of 2026-09-17 (`infra/docs/macros-traps.md`) was two hours and seventeen
|
|
//! minutes of `GO NPC done, GO OUT done, NEXT done, GO FRONTIER done`, every three brain seconds,
|
|
//! over three tiles — and nothing in the loop, the ratchet or the feed said so out loud. This
|
|
//! example is the thing that says so, on the dev box, before a release: it runs the real sim loop
|
|
//! from a checkpoint and reports every two-brain-minute window in which
|
|
//!
|
|
//! - the fly stood on **fewer than [`MIN_TILES`] distinct `(map, tile)`s**, or
|
|
//! - **one macro sequence repeated more than [`MAX_REPEATS`] times** (any period up to
|
|
//! [`MAX_PERIOD`] macros).
|
|
//!
|
|
//! Neither is a rule about what the fly *should* do — it is free to stand still, and silence
|
|
//! waits. Both are rules about what a *loop* looks like from outside: the macros finish, the
|
|
//! ledgers do not move, and the ground under the fly is the same three tiles.
|
|
//!
|
|
//! ```sh
|
|
//! FLY_ROM="$HOME/fly-plays-pokemon/Pokemon Red (U) [S][BF].gb" \
|
|
//! FLY_TRAP_CHECKPOINT=.local/checkpoints/release-viridian-loop.checkpoint \
|
|
//! FLY_TRAP_MINUTES=30 cargo run --release -p flysim --example trap_hunt
|
|
//! ```
|
|
//!
|
|
//! Without the ROM it prints how to run it and nothing else. The cartridge is never copied into
|
|
//! this repository; it is read from the path in `FLY_ROM` and nothing else. Neither is a
|
|
//! checkpoint: `.local/` is not tracked.
|
|
//!
|
|
//! | env | default | meaning |
|
|
//! | --- | --- | --- |
|
|
//! | `FLY_ROM` | — | the cartridge; without it this prints instructions |
|

//! | `FLY_TRAP_CHECKPOINT` | `FLY_MACRO_CHECKPOINT` | the `FLYSIM01` checkpoint to start from |
|
|
//! | `FLY_TRAP_MINUTES` | 30 | brain minutes to run |
|
|
//! | `FLY_TRAP_STUB` | unset | `1` drives the macros from a rotating stub over [`STUB_CHANNELS`] instead of the brain's readout, so two builds with different channel lists are comparable |
|
|
//! | `FLY_TRAP_MODE` | `macros` | `macros` or `raw` |
|
|
//! | `FLY_MACRO_BRAIN` | `FLY_DATASET`, else `data/fafb-v783` | the connectome |
|
|
//! | `FLY_TRAP_THREADS` | 4 | sweep threads |
|
|
//! | `FLY_TRAP_SEED` | 20260917 | seeds the palette |
|
|
//! | `FLY_TRAP_SEED_*` | unset | rebuilds session ledgers a restore starts empty: `PUSHED`, `EXHAUSTED`, `TALKED`, `BLOCKED`, `STOOD` (`examples/support/ledgers.rs`, row 57) |
|
|
//!
|
|
//! The frame order is `simloop.rs`'s, as `examples/palette_bench.rs` expresses it, so what this
|
|
//! measures is the loop that ships rather than a second implementation of it. Without a
|
|
//! checkpoint it refuses rather than booting the intro: a trap hunt is about a state the stream
