# Build, package & submit — guide (crewrift tier)

Reference notes, design rationale, and negative results (5).

#### 1. Crewrift static map facts live only in the vendored resource file; never arrive at runtime
`crewrift`

Crewrift vent, emergency-button, and task locations are NOT in the stream (the map object is a flat prerendered picture); they live only in the server-side map resource file (data/croatoan.resources, baked into the server image) that is never delivered to a player. A bot author without game-repo access cannot obtain them over the protocol, so vendor and parse the resource file at BUILD time, parsing the static map into belief at container startup (never per tick — the map is static for an episode). The file-order of task rects IS the 3000/7000+idx stream index, and the emergency button is a derived 28x34 rect centered on the bridge room. Building private starter crewrift policies (notsus, suspectra) needs a Metta-AI-org PAT (private repos); gate the build with informative errors and clean up token plumbing once the repos go public.

#### 2. Adding a new Crewrift player: template, context, nothing else
`crewrift` · tool: `build_player.sh`

Adding a new Crewrift player needs only three things wired into the build: a Dockerfile following the Nim template (clone public game at ARG CREWRIFT_REF, nimby --global sync, overlay source, nim c, slim runtime stage) OR the Python template (pip install deps + SDK, package on PYTHONPATH, bake CMD python -m <module>); a context decision (self-contained dir vs needs the shared SDK from the pinned public players repo); and nothing else if the player is not vendored — vendoring only changes where source is copied from, not how the image is built. The smallest complete from-scratch baseline is the Nim 'notsus' reference (decode Sprite-v1, move, press A), which doubles as a comparison opponent; crewborg (Python) is the full worked player and the source-verified reference for every id-range/label/offset; suspectra is the reference for wiring a latency-bounded meeting LLM. crewborg pip-installs player_sdk from the public players repo tarball at the pinned ref + copies the staged fork onto PYTHONPATH (deliberately NOT pip installing the lab package, which would pull coworld[auth]); notsus/suspectra clone the crewrift game at pinned CREWRIFT_REF and compile (a Nim-toolchain image incurs a multi-minute cold build). The single wrapper crewrift_lab/tools/build_player.sh <policy> builds any policy and prints the upload-policy command.

#### 3. Among Them config schema and the camelCase server_config migration
`crewrift`

Among Them (an Among-Us-style social-deduction game) is configured via JSON (file or COGAME_CONFIG_URI=file://...) with fields including minPlayers, imposterCount, tasksPerPlayer, killCooldownTicks, voteTimerTicks (24 FPS; 6000 ticks = 250s), buttonCalls, mapPath. The tokens array matches the slots array by index (tokens[0] belongs to slots[0]); each slot assigns name, role (crew|imposter), color — keep the arrays aligned or slots get the wrong tokens. Game-specific scenario knobs (imposter count, tasks-per-player, cooldown/timer ticks) often migrate from top-level config fields into a nested server_config dict using camelCase keys the binary expects; verify exact key names against what the server binary parses, not the old Python field names. Coworld authors changing the GAME package (not a policy) must build linux/amd64 game and baseline player images, run `coworld certify <manifest>` before `coworld upload-coworld <manifest>`; the full release flow is wrapped in among_them/upload.sh <version>.

#### 4. Crewrift PR/format gotchas: pre-existing prettier drift, blocked Graphite submit
`crewrift` · **negative result** · ⚠ _session-derived, unverified_

Crewrift repo PR/format gotchas: (1) `prettier --check README.md` fails on pre-existing README formatting drift, and running the formatter rewrites unrelated emphasis/list markers — treat as known drift and do NOT include the broad Prettier rewrite in an unrelated patch. (2) `gt submit` (Graphite) is blocked with 'You can only submit to repos synced with Graphite' — when a PR is needed, fall back to `gh pr create` only after explicit human approval per the repo's AGENTS rules, not silently.

#### 5. Decision: keep the Nim core, reject a near-term no-Nim rewrite
`crewrift`

Decision (2026-05-16): keep the Nim-core Coworld policy image and explicitly reject a full no-Nim Python rewrite as a near-term path; preserving the existing Nim perception/decision core was judged the better near-term investment than rewriting it. Treat any no-Nim rewrite as a deliberate project, not another compatibility layer.
