The current prototype implements a very early version of observe, autonomous
task choice, physical travel, work completion, resource change, and direct
player assistance. Its abstract task zones are explicitly transitional; the
next world-object migration is documented in
player assistance. NPC `gather_food` and `gather_wood` tasks now use finite
world `ResourceNode` instances (berry bushes and trees) rather than abstract
zone markers. The zone markers remain only for player interaction and
non-resource tasks. The migration is documented in
[the ResourceNode plan](RESOURCE_NODE_MIGRATION.md).

The farm, forest, guard, study, rest, and food locations are represented by

These markers are not the intended long-term work model. Food and wood should
first migrate to finite world `ResourceNode` instances. Storage, rest, study,
and guard behavior should later migrate to target types that match their actual
semantics rather than treating every usable object as a resource source.
**Migration status:** NPC `gather_food` and `gather_wood` no longer use the
farm and forest zones. They target `ResourceNode` instances (berry bushes and
trees) instead. The zone markers remain for:
- Player interaction (pressing E near farm/forest zones adds resources)
- Non-resource NPC tasks (patrol → guard_zone, study → study_zone, rest → rest_zone, eat → food_zone)

# The Steward — ResourceNode Migration Plan
## Progress Overview
| Phase | Description | Status |
|-------|-------------|--------|
| **1** | ResourceNode scene + registration | ✅ Complete |
| **2** | Food target selection + reservation | ✅ Complete |
| **3** | Authoritative extraction on completion | ✅ Complete |
| **4a** | Wood target selection (NPC) | ✅ Complete |
| **4b** | Player parity (extraction contract) | ⏳ Not started |
| **5** | Jajce world placement | ❌ Not started |
| **6** | Remove remaining zone model | ❌ Not started |
### Key divergences from the original plan
- **Zone fallback removed** (Phase 3): `gather_food`/`gather_wood` no longer fall back to `FarmZone`/`ForestZone` markers when no resource node is available. The original plan called for a logged fallback; instead, the NPC goes idle (via `navigation_failed` → wander) to guarantee resource conservation. The zone markers are still available for player interaction.
- **`navigation_failed` signal** (discovered during Phase 4): Added a separate signal pathway to distinguish genuine arrival from navigation failure. The original plan treated all "arrivals" uniformly.
- **Stale-path prevention** (discovered during Phase 4): Added `path_request_id` + `path_pending` to reject async path results that arrive after a new target was set or the NPC died.
- **Duplicate node_id detection** (discovered during Phase 4): Added startup validation that disables nodes with duplicate IDs and pushes an error.
### Bugs found and fixed
| # | Bug | Phase found | Fix |
|---|-----|-------------|-----|
| 1 | Navigation failure: empty path caused NPC to idle permanently | Phase 3 stump | `_report_arrival_once()` on empty path (later replaced by `navigation_failed` signal) |
| 2 | Unavailable-target deadlock: replan didn't trigger `npc_task_changed` | Phase 3 | Set `current_task = ""` so tick detects task change and emits signal |
| 3 | Zone fallback broke conservation (fixed during Phase 4 removal) | Phase 3 | Removed zone fallback for gather tasks; NPC stays idle if no node available |
| 4 | NPC collision blocking: NPCs physically blocked each other at shared destinations | Phase 3 | `collision_layer=2`, `collision_mask=1` on NpcVisual; `arrival_distance` 0.6→1.5 (later reverted to 0.6 after navigation_failed signal) |
| 5 | Repetitive task selection: NPC chose same task every tick | Phase 3 | `last_task` tracking with -1.5 score penalty when same task repeats |
| 6 | Wander didn't wander: wandered to rest marker instead of random offset | Phase 3 | Random ±6 unit offset from current position |
| 7 | `:=` infers from Variant: warnings treated as errors from `odig` | Phase 2-3 | Use `=` instead of `:=` for calls returning `Variant` |
| 8 | `Variant as StringName`: invalid cast | Phase 2-3 | Check for `null` on Dictionary `.get()` instead of casting |
| 9 | Empty-path re-entrancy: immediate arrival report caused re-entrant signal chain | Phase 4 | Defer to `stuck_counter`/`stuck_time` in `_physics_process` instead |
| 10 | Stale async path: `await physics_frame` result used after target or death changed | Phase 4 | `path_request_id`/`path_pending` guard |
| 11 | Stolen extraction: NPC extracted from node after reservation was lost | Phase 4 | Guard extraction with `node.reserved_by == npc.id` |

- migrate `gather_wood`;
- configure tree visuals and yields;
- route player interaction through the same extraction contract;
- add clear feedback for unavailable or depleted targets.
**Wood migration** ✅ complete:
- `gather_wood` uses `ResourceNode.find_available("gather_wood")` in WVM
- Tree_01 (15 wood, yield 3.0) and Tree_02 (12 wood, yield 3.0) placed
- Extraction follows same path as food (reserve → travel → work → extract → village resource delta)
- Zone fallback removed; NPC goes idle if no tree available
**Exit:** food and wood no longer require their abstract zones during normal
play. NPC and player extraction obey the same availability and depletion rules.
**Player parity** ⏳ not started:
- Player currently still uses zone-marker interaction in `player.gd`
- Player should use `ResourceNode.extract()` via proximity detection or raycast
- Player interaction bypasses reservation (player presses E at a node → extract if available)
- `PlayerInteraction.gd` exists as an empty stub

## Definition of done for the first migration
- Food and wood use actual finite world objects.
- NPCs select available targets and reserve them.
- NPC state stores stable target IDs rather than nodes or scene paths.
- Active visuals navigate to explicit interaction points.
- Work duration completes before extraction.
- Village resources increase only by the amount actually extracted.
- Depletion changes availability and presentation.
- Failure, interruption, and death release reservations.
- Old food and forest zones remain only as logged fallbacks.
- The player and NPCs can use the same extraction contract.
- Behavior is inspectable and covered by reproducible scenarios.
