Summary

Sprint 20 server deliverables — the Tier 2 social site template system and triangle escalation engine.

  • #163 Role definition schemaRoleSchema with trait/skill/relationship constraints, YAML deserialization
  • #164 Spatial requirement specificationSpaceSpec with sightline zones, privacy levels, traffic patterns
  • #165 Single-ownership modelTemplateOwnership component, TemplateReferenceMap resource, save/load integration
  • #106 Triangle definition schemaTriangleDef with conflict types (D-087 T1-T5), FNV-1a deterministic IDs
  • #107 Intra-template triangle generation — constraint satisfaction, NPC-to-role assignment, min 2 triangles/template
  • #250 Triangle escalation system — per-game-minute tick, tension → ToleranceThreshold → Active transition, TriangleCrisisEvent emission, ResolveTriangle stub (D-089 no cascade)

Protocol bumped v15 → v16 (TriangleCrisisEventWire on ObserverSnapshot). All msgpack fixtures regenerated.

3,214 lines added across 33 files. 1,195 tests passing, 0 failures.

Key decisions implemented

  • D-025: Social site as atomic template unit (single-ownership with reference links)
  • D-087: v0.1 triangle configuration (T1-T5 expressible in schema)
  • D-089: Self-contained forks, no cross-triangle cascade
  • D-026: TemplateOwnership preserved across tier transitions and save/load

Test plan

  • cargo test — 1,195 tests pass (1,061 lib + 25 template schema + 16 escalation + 51 serialization + 42 integration)
  • YAML round-trip for RoleSchema, SpaceSpec, TriangleDef
  • Constraint validation (self-referential, duplicate roles, min/max tile count)
  • TemplateOwnership + TemplateReferenceMap save/load round-trip
  • Escalation timing at expected game-minute, crisis event emission
  • D-089 resolve does not cascade, idempotent resolve
  • Seed-dependent escalation timing (D-087)
  • Protocol v16 fixture regeneration

Implements #163 (RoleSchema), #164 (SpaceSpec), #165 (TemplateOwnership
+ TemplateReferenceMap), #106 (TriangleDef), #107 (intra-template
triangle generation), and #250 (triangle escalation system) as the
foundational Tier 2 template system per D-025.

New content/template module with YAML-deserializable schema types,
ECS components for ownership/triangle state, escalation system
running on game-minute boundaries, and TriangleCrisisEvent emission.
Sample YAML templates at server/data/templates/.

Adds TemplateOwnership to NpcSaveState and TemplateReferenceMap to
SaveStateV1 so cross-template links survive save/load and tier
eviction (D-025, D-026). Both fields use serde(default) for backward
compatibility with existing saves.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Registers tick_triangle_escalation and apply_resolve_triangle systems
in SimulationPlugin. Adds TriangleCrisisEventWire to ObserverSnapshot
(protocol v16) for future client rendering of triangle crises (#250,
D-087). Observer emits empty vec by default; escalation system will
populate when triangles reach Active phase.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Updates all client-side msgpack test fixtures and server test
harnesses to include the new triangle_crisis_events field added
in protocol v16.

16 tests covering escalation timing, crisis event emission,
resolve command, D-087 seed-dependent timing, D-089 no-cascade,
and edge cases (dormant skip, saturation, idempotent resolve).

Review: server -> main (type: code)

Hoshe (Code Quality): REQUEST_CHANGES

Solid code quality throughout — determinism respected, good test coverage, clean Rust. Two issues block merge.

# File Severity Issue
1 server/src/perception/observer/mod.rs:417 warning triangle_crisis_events hardcoded to vec\![] — queue is populated by tick_triangle_escalation but never drained into snapshot. Protocol bumped to v16 advertising this field, but clients will always see empty.
2 server/src/simulation/save_state.rs + save_io.rs warning TriangleState components not persisted in SaveStateV1 — triangle phase/tension silently lost on save/load. No deferral comment like NpcMemory has.
3 server/src/content/template.rs:546-557 suggestion Fallback NPC assignment uses O(n²) Vec scan; no test covers fallback assigning same NPC to two roles
4 server/src/bridge/types.rs:692-700 suggestion TriangleCrisisEventWire.triangle_id is raw u64 with no From impl for the newtype — fragile inline .0 access when wiring is completed
5 server/tests/ suggestion Near-identical tests in module #[cfg(test)] and integration tests — consider consolidating

Tyre (Architecture): REQUEST_CHANGES

Well-structured architectural layering, clean content/ECS boundary, D-010 determinism respected throughout. Same two blocking issues.

# File Severity Issue
1 server/src/perception/observer/mod.rs:417 warning Same as Hoshe #1triangle_crisis_events never populated despite v16 protocol bump. Either wire the queue drain or defer the bump to v15.
2 server/src/simulation/save_state.rs + save_io.rs warning Same as Hoshe #2TriangleState not persisted, no documented deferral. Needs either serialization or an explicit comment + ticket.
3 server/src/content/template.rs:747-762 suggestion apply_resolve_triangle does O(N*M) scan — consider BTreeMap<TriangleId, Entity> index if triangle count grows
4 server/src/content/template.rs:506 suggestion generate_intra_template_triangles takes &mut World — inherently single-threaded, consistent with spawn.rs but worth noting
5 server/src/content/template.rs:413-443 suggestion TriangleDef.validate() doesn't catch dangling with_role references in relationship_constraints

Verdict: CHANGES REQUESTED

Both reviewers flag the same two warnings:

  1. Crisis event queue not wiredtriangle_crisis_events is always empty despite protocol v16 advertising it
  2. TriangleState not persisted — triangle escalation state silently lost on save/load with no documented deferral

Options: wire the queue drain + add save state serialization, or document both as intentional deferrals with TODO comments and tickets (matching the NpcMemory pattern in save_state.rs).

The TriangleCrisisEventQueue was populated by tick_triangle_escalation
but never drained into ObserverSnapshot — clients always saw an empty
vec despite protocol v16 advertising the field. Now drains the queue
each tick and converts to TriangleCrisisEventWire.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Triangle phase and tension were silently lost on save/load. Now
serialized as triangle_states vec in SaveStateV1, sorted by
triangle_id for determinism (D-010). Dedicated triangle entities
are respawned on load.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
TriangleDef.validate() now rejects relationship constraints where
with_role references a role not in the triangle's three roles.
Catches authoring errors at load time instead of silently producing
broken constraint data.

- Hoshe #3: replace O(n²) Vec scan in fallback NPC assignment with
  BTreeSet; prevent same NPC assigned to two roles in one triangle
- Hoshe #4: add From impls for RoleId, TriangleId, StableId, and
  TriangleCrisisEventWire — eliminate fragile .0 access on newtypes
- Hoshe #5: consolidate near-identical unit tests with integration
  counterparts — keep only unique tests in #[cfg(test)] module
- Tyre #3: replace O(N*M) scan in apply_resolve_triangle with
  BTreeMap<TriangleId, Entity> index for O(1) per-command lookup
- Tyre #4: document &mut World on generate_intra_template_triangles
- Observer snapshot uses TriangleCrisisEventWire::from instead of
  manual field mapping

  • Hoshe #5: Near-identical unit tests consolidated with integration counterparts
  • Tyre #3: apply_resolve_triangle O(N*M) scan replaced with BTreeMap<TriangleId, Entity> index — O(1) per command

Re-Review: server -> main (PR #72)

Round 2 — Fix verification: APPROVED

All three blocking warnings resolved:

  • triangle_crisis_events now drained from queue into snapshot
  • TriangleState persisted in SaveStateV1 with #[serde(default)]
  • TriangleDef.validate() catches dangling with_role references

Round 3 — Suggestion pass: APPROVED

3 of 6 suggestions addressed:

  • From<TriangleCrisisEvent> for TriangleCrisisEventWire — implemented
  • Test deduplication — cleaned up
  • Fallback NPC assignment — improved to O(n log n) via BTreeSet

Remaining suggestions (non-blocking):

# File Severity Issue
1 server/src/content/template.rs suggestion No dedicated test for dangling with_role validation
2 server/src/simulation/save_io.rs suggestion No integration test for save/load round-trip with populated triangle_states
3 server/src/perception/observer/mod.rs:394 suggestion .drain().into_iter() redundant on Vec

Verdict: APPROVED
