description	Implement or modify the deterministic world clock, calendars, NPC schedules, and route fallback policy in a standalone game. Use for the time-and-schedules phase only.

Implement time and schedules

Scope

Implement only G11 authoritative world time, derived calendars, NPC schedules, and schedule fallback routing. Navigation owns route mechanics; G11 requests it.

Inputs

• Absolute FORGE_ROOT and external GAME_ROOT with passing G04/G10 gates.
• Current source-tree/runtime/platform/catalog hashes and G11 writable surface.
• Selected world ID, release ID, and verified bundle hash for G11 fixtures.
• Validated clock/calendar and schedule definitions from imported content.
• Explicit condition, priority, missed-window, and fallback policies.

Outputs

• Game-owned time/schedule composition/extensions and typed schedule actions.
• Immutable clock/schedule summaries and focused boundary/replay tests.
• Forge-owned G11 completion record outside GAME_ROOT.

Invariants

• Keep src/isoworld, locks, and bundles immutable.
• Use integer simulation ticks only; never query wall-clock or raylib frame time.
• Do not reimplement navigation, dialogue, UI, or rendering.
• Never copy AGENTS.md, .agents, Forge skills, or phase evidence into GAME_ROOT.

Workflow

1. Read the time/schedule gate in docs/GAME_IMPLEMENTATION_PHASES.md.
2. Keep authoritative time as integer simulation ticks and derived calendar data.
3. Resolve schedule conditions and fallback entries in a documented stable order.
4. Route scheduled movement through navigation actions and reservation rules.
5. Test day boundaries, missed windows, unavailable destinations, and replay.
6. Publish clock/schedule summaries through immutable render state.

Completion

Complete when schedule resolution and fallback order are deterministic across boundary/missed-window fixtures, replay hashes match, focused/headless tests and the audit pass, and evidence is recorded outside GAME_ROOT. If the vendored runtime already meets G11, verify it without duplicating it in game code.
