+## End-to-end combat loop (NEO-86)
+
+Epic 5 Slice 1 capstone — tab-target lock, cast, defeat, and gig XP visibility **in Godot** without Bruno.
+
+**Flow:** boot hotbar sync (auto **`prototype_pulse`** bind on slot 0 when empty) → walk to orange **Dummy α** → **Tab** lock → digit **1** cast until defeat → verify combat HUD + **`breach`** gig XP refresh.
+
+| Step | Input / trigger | HUD / server outcome |
+|------|-----------------|----------------------|
+| Boot | Godot **F5** + server running | Hotbar slot 0 binds **`prototype_pulse`**; **`GigXpLabel`** hydrates **`breach: L1 · 0 xp`** |
+| Lock | **Tab** on **`prototype_target_alpha`** | Dummy brightens; **`CombatTargetHpLabel`** shows **`100/100`** |
+| Cast ×4 | **1** (respect ~3s cooldown) | **`CastFeedbackLabel`** steps damage; HP label tracks server snapshot |
+| Defeat | 4th pulse accept | **`Cast: … — defeated!`**; HP **`0/100 (defeated)`**; **`GigXpLabel`** → **`25 xp`** |
+| Deny | **1** on defeated target | **`ability_cast_denied: target_defeated`** |
+| Clear | **Esc** | HP label **`— (no lock)`** |
+
+**Cross-links:** [NEO-23](../docs/plans/NEO-23-implementation-plan.md) targeting · [NEO-28](../docs/manual-qa/NEO-28.md) cast deny HUD · [NEO-31](../docs/manual-qa/NEO-31.md) cast POST · [NEO-85](../docs/manual-qa/NEO-85.md) combat feedback + HP · [NEO-44](../docs/manual-qa/NEO-44.md) server gig grant.
+
+**Scripts:** `ability_cast_client.gd`, `combat_targets_client.gd`, `gig_progression_client.gd` — wired from `main.gd`.
+
+**Economy HUD:** **`GigXpLabel`** lives under **`EconomyHudSection/Body/`** (hidden when **`Economy HUD`** collapsed, NEO-75). Gig GET refreshes on boot and when cast accept carries **`targetDefeated: true`** only — not on every hit.
+
+**Preconditions:** **Server restart** before capstone run resets in-memory dummy HP and gig XP baseline.

+# NEO-86 — Manual QA checklist
+
+| Field | Value |
+|-------|-------|
+| Key | NEO-86 |
+| Title | E5M1-12: Playable tab-target combat capstone (Godot) |
+| Linear | https://linear.app/neon-sprawl/issue/NEO-86/e5m1-12-playable-tab-target-combat-capstone-godot |
+| Plan | `docs/plans/NEO-86-implementation-plan.md` |
+| Branch | `NEO-86-playable-combat-capstone` |
+
+## Preconditions
+
+- **Fresh dev player:** stop any running server, then start a new instance so in-memory **`dev-local-1`** dummy HP and gig XP reset.
+- **No Bruno/curl seeding** for this checklist — hotbar pulse bind is automatic (NEO-85 dev bootstrap).
+- NEO-85 combat HUD and NEO-44 gig progression GET landed on the same branch or `main`.
+
+## Combat math
+
+| Cast # | Expected `CastFeedbackLabel` | `CombatTargetHpLabel` |
+|--------|------------------------------|------------------------|
+| 1 | `Cast: 25 dmg → 75 HP` | `75/100` |
+| 2 | `Cast: 25 dmg → 50 HP` | `50/100` |
+| 3 | `Cast: 25 dmg → 25 HP` | `25/100` |
+| 4 | `Cast: 25 dmg → 0 HP — defeated!` | `0/100 (defeated)` |
+| 5 | `ability_cast_denied: target_defeated` | unchanged defeated |
+
+Respect ~3s **`prototype_pulse`** cooldown between casts.
+
+## Checklist
+
+1. Start server: `cd server/NeonSprawl.Server && dotnet run`.
+2. Run Godot main scene (**F5**). Confirm **`Economy HUD`** toggle is **on**; **`GigXpLabel`** shows **`breach: L1 · 0 xp`** after boot hydrate.
+3. Walk to orange **Dummy α** west of spawn **`(-3, -3)`** (flat lock ring on ground).
+4. Press **Tab** to lock **`prototype_target_alpha`** — dummy **brightens**; **`CombatTargetHpLabel`** shows **`Target HP: prototype_target_alpha 100/100`** (or **`…`** briefly until GET completes).
+5. Press **1** (hotbar slot 1 → index 0) four times with cooldown between hits. Verify cast feedback and HP label step per table above.
+6. After the lethal hit, **`GigXpLabel`** updates to **`breach: L1 · 25 xp`** (event-driven GET refresh).
+7. Press **1** again on the defeated dummy: **`CastFeedbackLabel`** shows **`ability_cast_denied: target_defeated`**; gig XP stays **25**.
+8. Press **Esc** to clear lock: **`CombatTargetHpLabel`** shows **`Target HP: — (no lock)`**; combat feedback labels remain readable.
+9. Uncheck **`Economy HUD`** — gig row hides with inventory/skills/recipes; check again — gig row repopulates.
+10. Regression: cast without lock still shows **`ability_cast_denied: invalid_target`** on **`CastFeedbackLabel`** (NEO-28).
+
+## Notes
+
+- Shared Postgres dev DB may retain prior gig XP totals — capstone baseline prefers **server restart** on in-memory mode.
+- Optional mid-session dummy-only reset (Development host): `POST /game/__dev/combat-targets-fixture` — see [NEO-85 manual QA](NEO-85.md).
+- Component-level combat HUD regression: [NEO-85 manual QA](NEO-85.md).
+
+## Acceptance
+
+- [ ] Steps 1–10 completable in one session without Bruno/curl.
+- [ ] **`prototype_target_alpha`** shows defeated state in HUD after step 5.
+- [ ] **`breach`** gig XP **25** visible in Godot after step 6.
+- [ ] No silent cast failures — every deny shows readable reason on **`CastFeedbackLabel`**.

+| **Server deps** | [NEO-82](https://linear.app/neon-sprawl/issue/NEO-82) cast + `combatResolution` (**Done**); [NEO-83](https://linear.app/neon-sprawl/issue/NEO-83) combat-targets GET (**Done**); [NEO-44](https://linear.app/neon-sprawl/issue/NEO-44) gig XP on defeat + GET (**Done**) |

+| **Pattern** | Capstone integration — [NEO-75](https://linear.app/neon-sprawl/issue/NEO-75) docs + manual QA primary; minimal client gap-fill for gig visibility |
+| **Server counterpart** | NEO-44 gig progression GET; Bruno-only verification is not prototype-complete per [full-stack epic decomposition](../../.cursor/rules/full-stack-epic-decomposition.md) |
+
+## Kickoff clarifications
+
+| Topic | Question | Agent recommendation | Answer |
+|--------|----------|----------------------|--------|
+| **Gig XP visibility** | Include gig XP in the Godot capstone? | **`GigProgressionClient` + `GigXpLabel`** in economy HUD; refresh after defeat cast — NEO-44 landed; NEO-75 capstone is Godot-only (no Bruno/curl). | **User:** Godot gig label + client. |
+| **Implementation scope** | Docs-only vs client code? | **Docs + manual QA primary**; add gig client wiring; fix integration gaps only if capstone QA fails on `main`. | **User:** docs-first; code for gig row or QA failures. |
+| **Session baseline** | Fresh server vs fixture POST only? | **Fresh server restart** before Godot **F5** — resets in-memory dummy HP + gig XP baseline (NEO-75 / NEO-44 manual QA precedent). | **Adopted** (kickoff default). |
+
+No other blocking decisions — combat loop HUD, hotbar pulse bootstrap, and event-driven combat-target refresh are landed in NEO-85; field names follow NEO-82 / NEO-44 server vocabulary.
+
+## Goal, scope, and out-of-scope
+
+**Goal:** Prove Epic 5 Slice 1 acceptance **in Godot**: tab-target lock, cast abilities, readable deny reasons, defeat **`prototype_target_alpha`**, and visible gig XP after defeat — without Bruno.
+
+**In scope (from Linear + [E5M1-12](E5M1-prototype-backlog.md#e5m1-12--playable-tab-target-combat-capstone-godot)):**
+
+- **`docs/manual-qa/NEO-86.md`**: numbered **single-session** capstone script — fresh dev player, Tab lock alpha, digit cast **`prototype_pulse`** until defeat, verify combat HUD + **`breach`** gig XP — **no Bruno/curl** steps.
+- **`client/README.md`**: **End-to-end combat loop** section — integration checklist (boot → Tab lock → cast → defeat → gig XP refresh chain); cross-links NEO-23/28/31/85.
+- **`GigProgressionClient`** + **`GigXpLabel`** — mirror **`SkillProgressionClient`** (NEO-37); boot hydrate + refresh when cast accept carries **`targetDefeated: true`**.
+- **Module alignment** (on story completion): update [`documentation_and_implementation_alignment.md`](../decomposition/modules/documentation_and_implementation_alignment.md) E5.M1 row + E5M1-12 backlog checkboxes; note Epic 5 Slice 1 client capstone complete.
+- **Integration fixes only if capstone QA fails** on current `main` wiring (unexpected deny, refresh gap, etc.).
+
+**Out of scope (from Linear + backlog):**
+
+- NPC AI (E5.M2), encounters/loot (E5.M3), group scaling.
+- Final combat VFX, floating damage numbers, player HP bar.
+- Full nine-gig catalog, hub swap, gig level curves.
+- Bruno-only verification as prototype-complete proof.
+
+## Acceptance criteria checklist
+
+- [x] Human completes **`docs/manual-qa/NEO-86.md`** with server + client; **`prototype_target_alpha`** shows defeated state in HUD.
+- [x] Epic 5 Slice 1 AC: combat readable in fixed isometric camera; no silent cast failures on deny.
+- [x] **`breach`** gig XP visible in Godot after defeat (≥ **25** from fresh-server baseline).
+- [x] Re-read [epic_05 Definition of Done](../decomposition/epics/epic_05_pve_combat.md#definition-of-done) for prototype minimums.
+
+## Implementation reconciliation (shipped)
+
+- **Client:** `gig_progression_client.gd` GET snapshot + **`gig_row`**; **`GigXpLabel`** under economy HUD; defeat-triggered refresh in **`_on_cast_result_received`**.
+- **Tests:** `gig_progression_client_test.gd`, `gig_feedback_refresh_test.gd` (5 cases pass).
+- **Docs:** [`NEO-86` manual QA](../manual-qa/NEO-86.md); `client/README.md` end-to-end combat loop section; E5M1 backlog + module alignment rows updated.
+- **Integration:** No capstone QA gaps on `main` beyond gig client wiring.
+
+## Technical approach
+
+### 1. Capstone manual QA script (`docs/manual-qa/NEO-86.md`)
+
+**Preconditions:** Stop any running server; start fresh (`dotnet run`) so in-memory **`dev-local-1`** dummy HP and gig XP reset. Godot **F5** with **no** prior curl/Bruno seeding.
+
+**Combat math** (from NEO-85 / NEO-82):
+
+| Cast # | Expected cast feedback | Target HP label |
+|--------|------------------------|-----------------|
+| 1 | `Cast: 25 dmg → 75 HP` | `100/100` → `75/100` |
+| 2 | `→ 50 HP` | `50/100` |
+| 3 | `→ 25 HP` | `25/100` |
+| 4 | `→ 0 HP — defeated!` | `0/100 (defeated)` |
+| 5 | `ability_cast_denied: target_defeated` | unchanged defeated |
+
+**Checklist outline:**
+
+1. Start server + client; confirm **`Gig XP:`** row shows **`breach`** at **0** xp (boot hydrate).
+2. Walk to orange **Dummy α** near spawn; **Tab** lock **`prototype_target_alpha`** — dummy brightens; **`CombatTargetHpLabel`** shows **`100/100`**.
+3. Press **1** four times (respect ~3s pulse cooldown); verify **`CastFeedbackLabel`** + HP label step as above.
+4. Verify **`GigXpLabel`** shows **`breach`** **`xp` 25** after lethal hit (event-driven GET refresh).
+5. Press **1** again — deny feedback; gig XP unchanged.
+6. **Esc** clear lock — HP label **`— (no lock)`**; combat feedback labels remain readable.
+7. Regression spot-check: cast without lock → **`invalid_target`** deny on **`CastFeedbackLabel`**.
+
+Document optional **`POST /game/__dev/combat-targets-fixture`** for mid-session dummy-only reset (NEO-85) — capstone baseline still prefers **server restart**.
+
+### 2. Gig progression client (`gig_progression_client.gd`)
+
+Mirror **`skill_progression_client.gd`**:
+
+- **`GET {base}/game/players/{id}/gig-progression`** — injectable HTTP, **`_busy`** guard.
+- **`parse_progression_json(text)`** static — require **`schemaVersion` 1**, **`mainGigId`**, **`gigs`** array.
+- Signals: **`progression_received(snapshot: Dictionary)`**, **`progression_sync_failed(reason: String)`**.
+- **`gig_row(gig_id: String, snapshot: Dictionary = {}) -> Dictionary`** — lookup by **`id`**; uses cached snapshot when second arg omitted.
+
+### 3. Gig XP HUD (`main.gd` + `main.tscn`)
+
+- Add **`GigProgressionClient`** node (scene or runtime like **`CombatTargetsClient`**).
+- Add **`GigXpLabel`** under **`UICanvas/EconomyHudSection/Body/`** below **`SkillProgressionLabel`**, above **`CraftRecipePanel`** — respects NEO-75 collapse toggle.
+- **`_render_gig_xp_label()`** — format **`Gig XP:\nbreach: L1 · 25 xp`** (prototype fixed level **1** from server); **`Loading…`** / error lines match skill label pattern.
+- **Refresh triggers (event-driven):**
+  - Boot: **`request_sync_from_server()`** in setup (parallel to skill progression).
+  - **`cast_result_received`** when **`accepted`** and **`resolution.targetDefeated === true`** → gig progression sync (NEO-44 grant is server-side on that accept; GET reconciles HUD).
+- Do **not** refresh gig XP on every cast accept — only boot + defeat transition (minimize HTTP chatter).
+
+### 4. README integration checklist
+
+New **`## End-to-end combat loop (NEO-86)`** section after NEO-85 combat HUD subsection:
+
+- Flow in prose: boot hotbar sync (auto pulse bind) → **Tab** lock dummy → digit cast → cast feedback + HP label refresh → defeat → gig XP refresh.
+- Cross-links: NEO-23 (targeting), NEO-28/31 (cast), NEO-85 (combat HUD), NEO-44 (server gig grant).
+- Pointer to **`docs/manual-qa/NEO-86.md`** as authoritative capstone script.
+- Note **`Economy HUD`** toggle hides gig row with other economy labels.
+
+### 5. Module alignment (implementation batch or story end)
+
+When acceptance criteria pass:
+
+- **`documentation_and_implementation_alignment.md`**: E5.M1 — note **NEO-86 landed**, Epic 5 Slice 1 client capstone complete.
+- **`E5M1-prototype-backlog.md`**: E5M1-12 checkboxes + landed note.
+- **`E5_M1_CombatRulesEngine.md`**: E5M1-12 row if not already marked.
+
+### 6. Integration fixes (conditional)
+
+Run capstone QA on **`main`** wiring before gig client work; if any step fails, fix minimal **`main.gd`** / client bug in this branch and note in plan **Decisions**. Expected path: gig client + docs only.
+
+## Files to add
+
+| Path | Purpose |
+|------|---------|
+| `docs/plans/NEO-86-implementation-plan.md` | This plan. |
+| `docs/manual-qa/NEO-86.md` | Capstone single-session manual QA (zero Bruno/curl). |
+| `client/scripts/gig_progression_client.gd` | GET gig-progression snapshot; parse v1; **`gig_row`** helper. |
+| `client/scripts/gig_progression_client.gd.uid` | Godot uid companion (tracked). |
+| `client/test/gig_progression_client_test.gd` | GdUnit: parse snapshot; **`gig_row("breach")`**; HTTP error path. AAA layout. |
+| `client/test/gig_feedback_refresh_test.gd` | GdUnit: cast accept with **`targetDefeated`** triggers gig sync (spy harness). AAA layout. |
+
+## Files to modify
+
+| Path | Rationale |
+|------|-----------|
+| `client/scripts/main.gd` | Wire **`GigProgressionClient`**; **`_render_gig_xp_label`**; defeat-triggered gig refresh in **`_on_cast_result_received`**. |
+| `client/scenes/main.tscn` | Add **`GigProgressionClient`** node + **`GigXpLabel`** under economy HUD body. |
+| `client/README.md` | End-to-end combat loop section; gig XP row docs; capstone manual QA link. |
+| `docs/decomposition/modules/documentation_and_implementation_alignment.md` | E5.M1 row — NEO-86 landed + Slice 1 client capstone complete (on story completion). |
+| `docs/plans/E5M1-prototype-backlog.md` | E5M1-12 acceptance checkboxes + landed note (on story completion). |
+
+## Tests
+
+| Path | Change |
+|------|--------|
+| `client/test/gig_progression_client_test.gd` | **Add:** GET parse v1 with **`breach`** row; invalid schema → failure signal; 404 path. |
+| `client/test/gig_feedback_refresh_test.gd` | **Add:** cast accept with **`targetDefeated: true`** triggers sync; non-defeat accept and deny do not. |
+
+**Manual verification:** [`docs/manual-qa/NEO-86.md`](manual-qa/NEO-86.md) — server + Godot; full defeat spine + gig XP visibility without curl.
+
+## Open questions / risks
+
+| Question or risk | Agent recommendation | Status |
+|------------------|----------------------|--------|
+| **Gig refresh on every accept** | Refresh only on **`targetDefeated`** + boot — avoids redundant GETs on non-lethal hits. | **adopted** |
+| **Gig label inside economy collapse** | Place under **`EconomyHudSection/Body`** — hidden when economy HUD collapsed (NEO-75); combat labels stay visible. | **adopted** |
+| **Overlap with NEO-85 manual QA** | NEO-86 supersedes as capstone script; keep NEO-85 as component-level regression reference. | **adopted** |
+| **Postgres dev DB retains gig XP** | Capstone preconditions require **server restart**; document that shared Postgres may show prior totals. | **adopted** |
+| **Integration gap on `main`** | Run capstone dry-run first; fix only if QA fails. | **adopted** — no logic gaps beyond gig client |

+# Code review — NEO-86 playable tab-target combat capstone (Godot)
+
+**Date:** 2026-05-25  
+**Scope:** Branch `NEO-86-playable-combat-capstone` · commits `8190614`–`b97cace` vs `origin/main`  
+**Follow-up:** Code review suggestions 1–4 addressed (alignment **Ready**, README link, two GdUnit cases).  
+**Base:** `origin/main`
+
+## Verdict
+
+**Approve with nits**
+
+## Summary
+
+NEO-86 closes **E5M1-12** and Epic 5 Slice 1 client acceptance: a capstone manual QA script, README integration checklist, **`GigProgressionClient`** mirroring **`SkillProgressionClient`**, **`GigXpLabel`** under the economy HUD, and defeat-triggered **`GET …/gig-progression`** refresh wired from **`_on_cast_result_received`**. No server changes; gig XP remains server-authoritative (NEO-44 grant + GET reconcile). Five new GdUnit cases pass locally. Residual risk is low — thin-client wiring atop NEO-85 combat HUD; brief lag between defeat cast feedback and gig label update until GET completes is an adopted trade-off (same pattern as combat-target refresh).
+
+## Documentation checked
+
+| Document | Result |
+|----------|--------|
+| [`docs/plans/NEO-86-implementation-plan.md`](../plans/NEO-86-implementation-plan.md) | **Matches** — kickoff decisions (Godot gig row, docs-first + gap-fill, fresh-server baseline), scope, acceptance checklist, and reconciliation align with shipped code. |
+| [`docs/plans/E5M1-prototype-backlog.md`](../plans/E5M1-prototype-backlog.md) · **E5M1-12** | **Matches** — AC checked; landed note cites gig client, manual QA, README. |
+| [`docs/decomposition/modules/E5_M1_CombatRulesEngine.md`](../decomposition/modules/E5_M1_CombatRulesEngine.md) | **Matches** — Status **Ready**; **E5M1-12 (NEO-86)** slice added; Slice 1 client capstone complete. |
+| [`docs/decomposition/modules/module_dependency_register.md`](../decomposition/modules/module_dependency_register.md) | **Matches** — E5.M1 note cites **NEO-86 landed** + capstone manual QA link. |
+| [`docs/decomposition/modules/documentation_and_implementation_alignment.md`](../decomposition/modules/documentation_and_implementation_alignment.md) · **E5.M1** | **Matches** — row updated with NEO-86 landed + Slice 1 client capstone note; **Status** **Ready** (aligned with `E5_M1_CombatRulesEngine.md`). |
+| [`docs/decomposition/modules/client_server_authority.md`](../decomposition/modules/client_server_authority.md) | **Matches** — gig XP from server GET only; defeat refresh triggered by wire **`targetDefeated`**, not client-side XP math. |
+| [`client/README.md`](../../client/README.md) | **Matches** — end-to-end combat loop section and test scope list; NEO-85 cross-link uses `../docs/manual-qa/NEO-85.md`. |
+| [`docs/manual-qa/NEO-86.md`](../manual-qa/NEO-86.md) | **Matches** — single-session Godot script, combat math table, economy HUD toggle step, no Bruno/curl; acceptance boxes intentionally unchecked pre-human QA. |
+| Full-stack epic decomposition | **Matches** — client capstone with Godot manual QA; not Bruno-only prototype proof. |
+
+## Blocking issues
+
+None.
+
+## Suggestions
+
+1. ~~**E5.M1 alignment status vs module doc** — `E5_M1_CombatRulesEngine.md` header is **Ready** with E5M1-01–12 landed; `documentation_and_implementation_alignment.md` E5.M1 row still **In Progress**. Promote to **Ready** (or add a one-line note why server slice remains in progress) so register, module page, and alignment table stay consistent.~~ **Done.** E5.M1 **Status** column promoted to **Ready**.
+
+2. ~~**Broken NEO-85 README link** — In `client/README.md` § End-to-end combat loop, `[NEO-85](NEO-85.md)` resolves relative to `client/` and 404s. Use `[NEO-85](../docs/manual-qa/NEO-85.md)` like the NEO-28/NEO-31 links in the same line.~~ **Done.**
+
+3. ~~**Schema-mismatch HTTP test gap** — Plan §Tests lists invalid schema → **`progression_sync_failed`** for `gig_progression_client_test.gd`; implementation covers parse unit test + 404 only. Add a mock 200 with `schemaVersion: 2` (or missing `mainGigId`) asserting **`progression_sync_failed`** with the schema mismatch reason — parity with `combat_targets_client_test.gd` **`test_invalid_schema_emits_sync_failed`**.~~ **Done.** `test_invalid_schema_emits_progression_sync_failed`.
+
+4. ~~**Deny-path refresh test gap** — Plan §Tests lists deny cast must not trigger gig sync; `gig_feedback_refresh_test.gd` covers defeat accept and non-defeat accept only. Add a third case with `accepted: false` and assert **`gig_sync_calls == 0`**.~~ **Done.** `test_denied_cast_skips_gig_progression_sync`.
+
+## Nits
+
+- Nit: **`GigRefreshHarness`** duplicates defeat-gated refresh logic from `main.gd` rather than testing `main.gd` directly — matches **`combat_feedback_refresh_test.gd`** / **`craft_feedback_refresh_test.gd`** precedent; acceptable for prototype scope.
+
+- Nit: Plan describes **`gig_row`** using a cached snapshot when the second arg is omitted; client has no internal cache — `main.gd` passes **`_last_gig_snapshot`** explicitly. Behavior is correct; plan wording could note cache lives in `main.gd`.
+
+- Nit: Between defeat cast accept and gig GET completion, **`CastFeedbackLabel`** shows authoritative defeat copy while **`GigXpLabel`** may still show pre-defeat XP until GET lands — same event-driven lag as combat HP label; optional future polish could show interim copy from cast resolution if UX matters.
+
+## Verification
+
+```bash
+cd /home/don/neon-sprawl/client
+godot --headless --path . -s res://addons/gdUnit4/bin/GdUnitCmdTool.gd --ignoreHeadlessMode \
+  -a res://test/gig_progression_client_test.gd \
+  -a res://test/gig_feedback_refresh_test.gd
+```
+
+**GdUnit (local run):** 7/7 passed (4 + 3 suites).
+
+**Manual:** [`docs/manual-qa/NEO-86.md`](../manual-qa/NEO-86.md) — fresh server restart, Godot **F5**, Tab lock **`prototype_target_alpha`**, four **`prototype_pulse`** casts, verify **`GigXpLabel`** **`breach: L1 · 25 xp`**, deny on defeated target, economy HUD collapse step 9.
