- Visible half-angle 150° → 100° (200° arc), matching average human binocular field. Blind spot widens from 60° to 160° — genuine vulnerability behind the character. - Forward half-angle stays at 60° (120° arc) — binocular overlap zone. - Peripheral zone represents combined sensory awareness: visual periphery + subconscious sound/motion tracking, not just eyes. - Per-character VisionConeConfig allows implants and perception modes (D-017) to widen beyond the unaugmented baseline. - Fog shader: smooth back-edge gradient via smoothstep blend between Layer 2 (peripheral) and Layer 3 (deep fog), eliminating blocky stair-stepped tiles at the rear of the vision cone. - D-015 updated with physiological basis and per-character config. - D-017 updated with vision cone modification by perception modes. - D-020 updated with protocol versioning policy: PROTOCOL_VERSION gates wire format, not gameplay parameters. - DB backup after sprint 21 close.

Decisions
Confirmed decisions, open questions, and rejected alternatives for The Settled Reach.
Decisions are split by domain. Each agent's briefing indicates which files to read. When in doubt about where a decision belongs: if it constrains how we build, it's architecture. If it defines what we build, it's scope. If it defines what the player experiences, it's content or perception. If it defines how the team works, it's process.
Cross-domain decisions live in one file with cross-reference notes in related files. Split threshold: when any file exceeds ~350 lines, review whether it should split.

Querying Decisions
The SQLite database contains a decisions table synced from these files. Common queries:
# All active architecture decisions
tooling/db/sqlite-query "SELECT id, title FROM decisions WHERE domain='architecture' AND status='active'"
# Decisions without implementing tickets
make decisions-orphan
# Decision coverage by domain
make decisions-coverage
Adding a Decision
- Edit the appropriate domain file
- Follow the existing format (
### D-NNN: Titleheading) - Commit — the pre-commit hook runs
decisions-syncautomatically - Update relevant agent briefings if needed
