…n cells, backend toggle (Q), witness export Fork addition (upstream game modules byte-identical; bridge wraps from outside, index.html +8 marked lines): - app/quilt/kernel.mjs — vendored minimal quilt kernel: BIND/LINK/ EFFECT/VIEW/TICK/FORGET, prev_hash chain (FNV-1a-64 UTF-8 bytes, genesis 0x0000000000000000), fleet canary verified, honest FORGET on trim, witness() export in kev harness JSONL shape (this toy is a witness-log producer for kev-substrate-competition's replay.py). - app/quilt/bridge.mjs — wraps City/EffectsManager/AgentManager from outside: buildings/agents BIND, dependencies+walks LINK, fires/ sparkles/rockets/status EFFECT, scene VIEW, aggregate TICK every 30th frame. - app/quilt/pane.js — the 'see the backend in production' toggle (Q or ◈ button): phosphor pane, live cell tail, opcode counters, coherence, chain head, witness.jsonl export. - tests/quilt.test.mjs — 10 tests, node --test, zero deps: canary byte law, genesis chaining, tamper->coherence drop, honest FORGET, witness field-for-field harness interop + replay-verify, wrapper fidelity (originals still run, order intact), tick cadence, creator-credit regression guard. - CI made real: npm ci -> npm install (no lockfile existed, ci failed by construction), lint no-op -> npm test.

Fleet fork addition for the Cocapn ecosystem. The city gets a live quilt substrate: every building/agent BINDs, every dependency and walk LINKs, every fire/sparkle/rocket/status is an EFFECT, the scene is a VIEW, frames TICK — all as prev_hash-chained cells with the fleet canary. Press Q (or ◈) and a phosphor pane streams the backend while you play; export the witness JSONL and it replays in kev-substrate-competition's harness/replay.py.
Respect for the original: city.js/effects.js/agents.js/controls.js byte-identical; the bridge wraps from outside; index.html +8 marked lines; creator credit guarded by a regression test. Upstream files otherwise untouched. 10/10 node --test green; CI fixed to actually run tests (npm ci had no lockfile; lint step was a no-op).
