Expected resolution: **(a) cursor reverts to default shape only, no verb labels** — "the character still physically orients to the target, but receives no information from their insert."

They must be consistent. +13. **GameState.insert_active propagates**: Changes to `GameState.insert_active` are picked up by both systems on next update. +14. **Decision amendment recorded**: The resolved OQ-07 decision is documented in `decisions/perception.md` or `decisions/scope.md` as an amendment to D-056 or D-057. + +### Regression markers +- **Existing cursor state tests pass**: All 19 tests in `test_cursor_states.gd` must still pass. +- **Existing interaction list tests pass**: All tests in `test_interaction_list.gd` must still pass, including `test_insert_off_hides_interaction_list`. +- **Sprint suppression still works**: `test_sprint_suppresses_interaction_list` still passes. +- **Weapon mode suppression unchanged**: `test_weapon_mode_suppresses_interactions` still passes. +- **D-045 invariance**: Cursor behavior does NOT change by zone or narrative state. + +--- + +## Test Files + +- `client/tests/test_bug_report_ring_buffer.gd` — automated tests for #507 ring buffer +- `client/tests/test_insert_off_behavior.gd` — automated tests for #522 insert-off behavior + +## Run Command + +```bash +make test-client +``` + +Or headless via gdUnit4: +```bash +cd client && godot --headless --quit --path . addons/gdUnit4/bin/GdUnitCmdTool.gd \ + --testsuites "tests/test_bug_report_ring_buffer.gd,tests/test_insert_off_behavior.gd" +``` + +## Verification Checklist (fill in after implementations land) + +- [ ] All happy path tests pass +- [ ] All edge case tests pass +- [ ] All integration tests pass +- [ ] Regression: `test_cursor_states.gd` — unchanged +- [ ] Regression: `test_interaction_list.gd` — unchanged +- [ ] Regression: `test_anti_tedium.gd` — unchanged +- [ ] `decisions/perception.md` or related file updated with OQ-07 resolution +- [ ] `inputs.jsonl` format verified against `tooling/test-client --replay` manually +- [ ] `seed.txt` present in captured bug report diff --git a/docs/test-reports/sprint-11-522-preliminary.md b/docs/test-reports/sprint-11-522-preliminary.md new file mode 100644 index 000000000..f9e526d30 --- /dev/null +++ b/docs/test-reports/sprint-11-522-preliminary.md @@ -0,0 +1,120 @@ +# Preliminary Review: #522 OQ-07 Implementation + +- **Date**: 2026-02-19 +- **Build**: working tree (uncommitted, pending #507 + Tyre arch review) +- **Spec reference**: D-056, D-057 +- **Reviewer**: Hoshe (QA Engineer) +- **Status**: PRELIMINARY — full test report follows after task #4 unblocks + +--- + +## Summary + +The OQ-07 resolution implements **option (a): cursor shape still changes, verb labels suppressed**. +Implementation is correct.

In v0.1 this means `set_insert_active(true)` is called ~10 times per second on cursor, interaction_list, and interaction_prompt. + +This is harmless now — each setter is a simple bool write with a conditional. If insert state becomes server-driven in a future sprint (a character without an insert?), adding a change-gate would avoid unnecessary `_hide()` tween calls. + +**Recommendation**: Note in a ticket or code comment for v0.2. Not a blocking issue. + +### OBS-2: insert_active response timing inconsistency between components + +**Location**: `main.gd` inside `if snapshot != null:` block (lines 65-127) + +`interaction_prompt._process()` runs every frame and checks `_insert_active` directly. `interaction_list.update_from_state()` and `cursor_renderer.set_insert_active()` only get called when a new snapshot arrives. + +In v0.1 (insert always true, no server-driven changes), this is invisible. If a future sprint allows toggling insert state without a new snapshot (e.g., a UI action), `interaction_prompt` would respond immediately while `interaction_list` and `cursor_renderer` would lag by up to one tick. + +**Recommendation**: Acceptable for v0.1. For future server-driven insert toggling, consider propagating insert state every frame rather than per-snapshot. Track as technical debt. + +### OBS-3: set_insert_active(false) calls _hide() redundantly in next _process() + +**Location**: `interaction_prompt.gd` lines 81-84 and 29-32 + +`set_insert_active(false)` immediately calls `_hide_prompt()` (sets `_is_showing = false`). Then `_process()` fires, sees `not _insert_active`, checks `if _is_showing:` — which is now `false` — and skips the second `_hide_prompt()` call. Correct behavior, slightly redundant guard.
