# Code review — NEO-82 Wire ability-cast into combat engine + cast response
**Date:** 2026-05-25
**Scope:** Branch `NEO-82-wire-ability-cast-combat-resolution` · commits `4126ac9``e8be100` vs `origin/main`
**Base:** `origin/main`
**Follow-up:** Code review suggestions and nits addressed in follow-up commit on `NEO-82-wire-ability-cast-combat-resolution`. Bugbot + CI fixes in `52bf9fc` (definition-before-resolve; Bruno beta/alpha isolation).
## Verdict
**Approve with nits**
## Summary
NEO-82 delivers **E5M1-07**: after E1.M4 cast gates pass, `AbilityCastApi` invokes `CombatOperations.TryResolve`, returns nested wire `combatResolution` on accept, maps combat denies (notably `target_defeated`) to JSON cast denies without cooldown commit, and replaces the global prototype cooldown with per-ability catalog `cooldownSeconds` on successful resolve. Handler flow, DTO shape, kickoff decisions (nested block, no cooldown on defeated deny), Bruno happy + defeat spine, and README updates align with the implementation plan. Four new integration tests cover zero-damage accept, four-pulse defeat chain, and guard-vs-pulse catalog cooldown; existing cast tests assert resolution fields. Residual risk is low — server-only HTTP extension with clear deny vocabulary; module tracking docs should sync on merge (same follow-up pattern as NEO-81).
## Documentation checked
| Document | Result |
|----------|--------|
| [`docs/plans/NEO-82-implementation-plan.md`](../plans/NEO-82-implementation-plan.md) | **Matches** — kickoff decisions, scope, acceptance checklist, expected cast table, and reconciliation align with code. |
| [`docs/plans/E5M1-prototype-backlog.md`](../plans/E5M1-prototype-backlog.md) · **E5M1-07** | **Matches** — AC checked, landed note added. |
| [`docs/decomposition/modules/E5_M1_CombatRulesEngine.md`](../decomposition/modules/E5_M1_CombatRulesEngine.md) | **Matches** — Status cites E5M1-07 NEO-82 landed; **Related implementation slices** entry added. ~~Partially matches~~ **Done.** |
| [`docs/decomposition/modules/module_dependency_register.md`](../decomposition/modules/module_dependency_register.md) | **Matches** — E5.M1 note includes NEO-82 landed. ~~Partially matches~~ **Done.** |
| [`docs/decomposition/modules/documentation_and_implementation_alignment.md`](../decomposition/modules/documentation_and_implementation_alignment.md) | **Matches** — E5.M1 row cites NEO-82 cast → `combatResolution`. ~~Partially matches~~ **Done.** |
| [`docs/decomposition/modules/client_server_authority.md`](../decomposition/modules/client_server_authority.md) | **Matches** — server validates and computes all combat outcomes; client unchanged (NEO-85). |
| [`docs/decomposition/modules/pvp_combat_integration.md`](../decomposition/modules/pvp_combat_integration.md) | **N/A** — prototype NPC targets only. |
| [`server/README.md`](../../server/README.md) | **Matches** — cast `combatResolution` table, `target_defeated` deny, catalog cooldown policy, combat engine cross-link. |
| Full-stack epic decomposition | **Matches** — plan documents NEO-85 client counterpart; no Godot change in scope. |
| Manual QA | **N/A** — kickoff skip; Bruno + README sufficient. |
## Blocking issues
None.
## Suggestions
1. ~~**Module doc status + slice entry** — In `docs/decomposition/modules/E5_M1_CombatRulesEngine.md`, update **Status** to cite **E5M1-07 NEO-82 landed** (cast POST returns `combatResolution`), and add **E5M1-07 (NEO-82)** under **Related implementation slices** linking the plan and README ability-cast section (mirror NEO-81 landed pattern).~~ **Done.**
2. ~~**Dependency register + alignment table** — Extend the **E5.M1 note** in `module_dependency_register.md` and the E5.M1 row in `documentation_and_implementation_alignment.md` with **NEO-82 landed:** `AbilityCastApi` → `CombatOperations.TryResolve`, nested `combatResolution`, per-ability catalog cooldown, `target_defeated` cast deny.~~ **Done.**
3. ~~**Bruno defeat spine HP stepping** — Plan §6 calls for asserting HP 75 → 50 → 25 → 0 on casts 14; `Post cast lock pulse defeat spine.bru` only captures/asserts the fourth cast. Consider storing intermediate cast bodies in pre-request and asserting `targetRemainingHp` on each pulse for stronger manual lock-in (non-blocking — fifth deny + integration test cover the critical path).~~ **Done.**`neo82CastResults` stores all four casts; tests assert HP stepping.
## Nits
- ~~Nit: `PostAbilityCast_ShouldDefeatTargetAfterFourPulses_ThenDenyTargetDefeated` runs pulses 13 inside **Act**; move them to **Arrange** for stricter AAA (same note as NEO-81 four-pulse pattern).~~ **Done.** — Pulses 13 in Arrange; Act is 4th + 5th cast; Assert includes HP stepping.
- ~~Nit: After successful `TryResolve`, `TryGetDefinition` runs again solely for `CooldownSeconds``CombatOperations` already loaded the definition internally. Acceptable for thin handler clarity; optional future refactor if catalog lookups become hot-path. **Deferred** — no hot-path concern in prototype.~~ **Done.**`TryGetDefinition` moved before `TryResolve` so cooldown lookup cannot deny after HP mutation (Bugbot fix).
- Nit: `AbilityPrototypeCooldown.GlobalDuration` is `[Obsolete]` but retained — matches plan; no remaining runtime references in tests or accept path. **No action** — intentional per plan.
## Verification
```bash
cd /home/don/neon-sprawl/server
dotnet test NeonSprawl.Server.Tests/NeonSprawl.Server.Tests.csproj \
--filter "FullyQualifiedName~AbilityCastApiTests|FullyQualifiedName~CooldownSnapshotApiTests"
dotnet test NeonSprawl.Server.Tests/NeonSprawl.Server.Tests.csproj
```
**AbilityCast + CooldownSnapshot tests:** 22/22 passed (local run).
**Full suite:** 394/394 passed (local run).
**Bruno (manual):** Run `bruno/neon-sprawl-server/ability-cast/` folder — happy cast + defeat spine (seq 23, ~10s pre-request cooldown waits).
