The Settled Reach

A top-down immersive sim — occlusion-based detective game with combat elements, set in an original science fiction universe. Single-character perspective, asymmetric information as core mechanic, Rimworld-style storyteller. Godot 4 client + Rust/bevy_ecs simulation server via subprocess/IPC.

DevOps

See docs/DEVOPS.md for build, test, lint, and CI procedures. All development operations go through the top-level Makefile — run make for a summary of targets.

Agent Instructions

Team boundaries

Your team identity is $WORKTREE_TEAM. All work must stay within the current working directory.

• All file paths are relative to the current working directory (e.g. server/src/bridge/types.rs).
• Do NOT navigate to parent or sibling directories (../, ../client/, etc.) unless explicitly instructed. Do NOT use absolute paths to reach other team directories.
• Do NOT write auto-memory files for other teams. If $WORKTREE_TEAM is server, do not write to memory paths containing client, main, etc.
• For context: each team has its own directory via git worktrees, sharing a parent directory (settled-reach/). The .git file points to a shared git directory — do not follow it to determine your working root.
• Exception — stale git lock files: If a git command fails with index.lock: File exists, you may remove the lock file for your own team only (e.g. main/.git/worktrees/$WORKTREE_TEAM/index.lock). Never touch lock files belonging to other teams.
• Never chain git commands in a single Bash call (e.g. git add ... && git commit ...). The shared .git directory means concurrent index access from the same terminal creates index.lock collisions. Always run git add and git commit as separate sequential Bash calls.

Database

The ticketing database (settledreach.db) lives in the parent directory shared across all worktrees — it is not tracked in git. A backup is committed to docs/backups/settledreach.db.backup via main only.

Before starting work

1. Read your sprint briefing at docs/sprints/sprint-N/{team}.md for current tasks
2. Use tooling/db/ticket show <id> for full ticket details
3. Read the relevant decisions/*.md domain file(s) referenced in the briefing
4. Background context: docs/briefings/{your-name}.md, docs/discussions/

CLI tools

Prefer CLI wrappers over raw SQL. Never use the sqlite3 CLI — it crashes in Claude Code (std::bad_alloc). Use the wrapper scripts instead.

Tool	Command	Full reference
Tickets	tooling/db/ticket list, show, create, assign	/ticket skill
Sprints	tooling/db/sprint status, start-work, prepare	/sprint-start skill
SQL queries	tooling/db/sqlite-query "SELECT ..."	—
SQL writes	tooling/db/sqlite-exec "UPDATE ..."	—
Decisions	tooling/db/decision next, claim, check-dupes	—
Doc search	tooling/db/qdrant-search "query"	/docs-search skill
Doc index	tooling/db/qdrant-index path/to/file.md	/docs-search skill

Testing preferences

• Prefer live Gauntlet testing over mocks. For visual tests and rendering verification, use the full client/server pipeline (--test-mode + SR_LIVE=1) instead of TestHarness mocks. The Gauntlet test world produces production-identical data. Mocks can mask rendering bugs by taking different code paths.
• Gauntlet rooms are immutable. Never modify existing rooms — new systems get new rooms. This ensures StableId determinism and fixture stability.
• Three test tiers: (1) Live server — highest fidelity, (2) MessagePack replay via Protocol.decode_snapshot() — for unreachable rooms, (3) TestHarness mock — for UI-only tests where fog data doesn't matter.
• make fixtures-gauntlet regenerates real server snapshot fixtures from the Gauntlet world.

File conventions

• Decisions: domain files in decisions/ (see decisions/README.md for index)
• Decision IDs: D-NNN (confirmed), Q-NNN (open questions), R-NNN (rejected)
• Claim IDs before writing: tooling/db/decision claim D <domain> "title" — prevents ID collisions across worktrees
• Diagrams: .d2 source + .png renders in docs/diagrams/{category}/. Create or update diagrams via /d2-diagram when D-records are added or modified.
• Discussion rounds: numbered sequentially, archived to docs/discussions/ when complete
• Briefings: one per agent, updated after decision-producing rounds
• Tickets: managed via tooling/db/ticket CLI or /ticket skill
