## State at session pause (2026-05-09)

**Branch:** `feat/language-shim-experiment` (on origin only — local was on this branch when paused)
**Latest commit:** `30d435d` (fix commit on top of `042e4e2` initial PR)
**PR:** [#46](https://github.com/NAJEMWEHBE/unreal-ai-connection/pull/46) — state OPEN, never merged
**Tests:** 143 pass locally on the branch

**Why:** The language-shim experiment from the PR #37 retrospective. Four handlers shipped (47 UE + 3 synthetic = 52 total tools after merge): 2 C++ canonical (`find_console_variables`, `inspect_static_mesh`) and 2 bridge-side Python shims (`get_camera_transform`, `set_camera_transform`).

## In-flight bot findings (status)

| Finding | Status |
|---|---|
| Codex P1 — `set_camera_transform` partial-update destruction | Fixed in `30d435d` (preserves omitted side via get-first round-trip) |
| Codex P2 + Gemini medium — log window of 200 too small | Fixed in `30d435d` (1000 = full ring) |
| Gemini medium — NaN/Infinity in `_num` | Fixed in `30d435d` (added `import math` + `math.isfinite()`) |
| Gemini medium — int64 accumulators in `inspect_static_mesh` | Fixed in `30d435d` |
| Gemini medium — `LoadObject<UObject>` instead of `UEditorAssetLibrary::LoadAsset` | **Dismissed** with rationale (consistency with all other inspect/compile/etc. handlers; `EditorScriptingUtilities` already a Build.cs dep) |

## Important: an earlier reset wiped local work

During this session, between my initial `042e4e2` push and the fix commit, the local repo was somehow reset to main (PR #45 state) and the local feat/language-shim-experiment branch was deleted. Possibly user-initiated. The remote PR #46 was untouched, so I recovered by `git checkout feat/language-shim-experiment` from the remote, then re-applied the fixes as `30d435d`.

If the next session sees similar local-reset behavior with PR #46 still open on the remote, the recovery is: fetch + checkout the remote branch.

## What's pending

1. **Wait for codex + gemini re-review on `30d435d`** — typically 3-5 min after push. The `gh api repos/NAJEMWEHBE/unreal-ai-connection/pulls/46/reviews` command shows current state.
2. **Self-merge if clean** — `gh pr merge 46 --merge` once mergeStateStatus is CLEAN AND the bots have re-reviewed (or stayed silent, indicating they have nothing new to flag — this is the established pattern from PRs #39-#45).
3. **Sync local main + delete branch** afterward.

## Tier 2 + experiment scoreboard at pause

- PRs #39-#45 all merged (Tier 1 closeout + Tier 2 fully shipped)
- PR #46 (language-shim experiment) pushed with fixes, awaiting merge
- Handler counts: pre-session = 36; PRs #39-#45 = 48; PR #46 (when merged) = 52
- HANDOFF.md was NOT updated this session — still reflects 36 handlers / pre-Tier 2 state. Future session should consider updating HANDOFF.md to capture the Tier 2 surface, the SYNTHETIC_TOOLS bridge pattern, the FUCMCPEventBus + FUCMCPTaskRegistry frameworks, and the language-shim conclusions.
