# Code review — NEO-87 prototype NpcBehaviorDef catalog + CI

**Date:** 2026-05-25  
**Scope:** Branch `NEO-87-e5m2-npc-behavior-catalog-schemas-ci` · commits `846da90`–`6fd9694` vs `origin/main`  
**Base:** `origin/main`  
**Follow-up:** Restored missing `prototype_elite_mini_boss` row; `validate_content.py` passes with 3 npc behavior ids.

## Verdict

**Approve with nits**

## Summary

NEO-87 lands E5M2-01 content-only work: `npc-behavior-def.schema.json`, NPC behavior validation in `scripts/validate_content.py` (mirroring NEO-76 ability pattern), and thorough doc updates (E5.M2 freeze table, `content/README.md`, CT.M1, alignment register, backlog checkboxes). Schema shape, CI gate constants, and Python validation helpers align with the kickoff plan. **Follow-up:** the initial commit shipped a two-row catalog (elite row dropped before commit); restored per freeze table — CI now passes with all three ids.

## Documentation checked

| Document | Result |
|----------|--------|
| [`docs/plans/NEO-87-implementation-plan.md`](../plans/NEO-87-implementation-plan.md) | **Matches** — reconciliation and AC align with three-row catalog after follow-up fix. |
| [`docs/plans/E5M2-prototype-backlog.md`](../plans/E5M2-prototype-backlog.md) · **E5M2-01** | **Matches** — AC and “Landed” note accurate once catalog is complete. |
| [`docs/decomposition/modules/E5_M2_NpcAiAndBehaviorProfiles.md`](../decomposition/modules/E5_M2_NpcAiAndBehaviorProfiles.md) | **Matches** — freeze table, catalog file, and CI rules line aligned. |
| [`docs/decomposition/modules/CT_M1_ContentValidationPipeline.md`](../decomposition/modules/CT_M1_ContentValidationPipeline.md) | **Matches** — NPC behavior PR gate paragraph added. |
| [`docs/decomposition/modules/documentation_and_implementation_alignment.md`](../decomposition/modules/documentation_and_implementation_alignment.md) · **E5.M2** | **Matches** — **NEO-87 landed** accurate after catalog fix. |
| [`docs/decomposition/modules/module_dependency_register.md`](../decomposition/modules/module_dependency_register.md) | **Matches** — E5.M2 note cites **NEO-87 landed** with passing CI. |
| [`content/README.md`](../../content/README.md) | **Matches** — `npc-behaviors/` row + E5 Slice 2 freeze paragraph (ids and rules). |
| [`docs/decomposition/modules/client_server_authority.md`](../decomposition/modules/client_server_authority.md) | **N/A** — no runtime authority changes; content-only. |
| Full-stack epic decomposition | **Matches** — E5M2-01 is **server/content + CI** only; kickoff explicitly defers Godot to E5M2-04+ / NEO-97 / NEO-98. No `docs/manual-qa/NEO-87.md` required. |

## Blocking issues

1. ~~**Missing third catalog row — CI fails.** [`content/npc-behaviors/prototype_npc_behaviors.json`](../../content/npc-behaviors/prototype_npc_behaviors.json) contains only `prototype_melee_pressure` and `prototype_ranged_control`. The E5M2 three-id gate requires `prototype_elite_mini_boss` as well. Running validation:~~ **Done.** Restored `prototype_elite_mini_boss` row per kickoff freeze table; `validate_content.py` exits 0 with `3 unique npc behavior id(s)` (`24cbd9b`).

## Suggestions

1. ~~**Defer “landed” doc claims until CI is green** — After fixing the catalog, re-run validation and confirm plan reconciliation, E5M2-01 backlog “Landed” note, alignment register, and module register accurately reflect a passing gate (same pattern as [NEO-76 review follow-up](../reviews/2026-05-24-NEO-76.md)).~~ **Done.** Validation green; existing doc claims now accurate — no further doc edits required.

2. **Optional: one-row-per-`archetypeKind` gate** — The three-id frozenset already implies one row per archetype for E5M2-01. If the roster grows in a follow-up issue, consider an explicit archetype coverage check; not required for this slice.

## Nits

- ~~Nit: Commit subject “ship prototype … catalog” reads complete while the catalog file is incomplete — minor messaging; resolved when elite row lands.~~ **Done.** Elite row restored in follow-up commit.

## Verification

```bash
# From repo root
python3 -m venv .venv-content && .venv-content/bin/pip install -r scripts/requirements-content.txt
.venv-content/bin/python scripts/validate_content.py
# Expect: content OK … 1 npc behavior catalog file(s) … 3 unique npc behavior id(s)

# Negative smokes (optional, after fix)
# — duplicate id across rows → non-zero exit
# — remove one frozen id → gate error
# — leashRadius <= aggroRadius → numeric gate error
```

PR gate (`.github/workflows/pr-gate.yml`) runs the same script; no additional workflow changes needed for this story.
