| # Prompt — enable the Search operator (turn on the full DSL) | |
| Search is currently gated off by default; turn it on so the engine can use the whole DSL. Verified the exact location. Airgap untouched (Search operates on opaque IDs). `pytest` + `tsc` after. | |
| ## 1. Enable Search injection (engine_v2/synthesize.py) | |
| `DEFAULT_RATES` (~lines 51-55) has `"search": 0.0`. Set it to a **modest non-zero** rate so Search appears in the population without dominating or blowing up runtime: | |
| - `"search": 0.05` | |
| Keep Search's existing safety **caps** (k ≤ 4 selected, ≤ 200 candidate columns) — those bound each Search's cost; don't remove them. The injection gate at ~line 109 (`rates["search"] > 0`) already does the rest. Leave the other rates (split/fitapply/effect) unchanged. | |
| ## 2. Update the "Search" tile copy (web/app/Lab.tsx, DSL vocabulary) | |
| The Search tile says "Nested feature search — available but off by default." Change it to reflect that it's now on, e.g. "Nested feature search — runs a small gene-ranking inside the program (bounded: ≤4 genes from ≤200 columns)." Remove the "off by default" wording. | |
| ## 3. (Recommended) a per-run toggle so it can be turned off for speed | |
| Search is the one heavy operator — every Search node runs an inner gene-ranking, so runs will be slower. To keep control: | |
| - `RunRequest` gains `enable_search: bool = True`. The `_worker` maps `enable_search=False` → pass a rates override with `search: 0.0`; `True` → use the default (0.05). (Thread the rates override into `run_v2_pipeline*` → `synthesize`, which already accepts a `rates` dict, ~line 212/220.) | |
| - Frontend: a Parameters checkbox **"Enable Search operator"** (default ON). Tooltip: "Lets programs run a small built-in gene-search (bounded). Powerful but the heaviest operator — turn off for faster runs." | |
| - If this part is too much scope, at minimum do Parts 1-2 (enable by default); the toggle is the nice-to-have. | |
| ## CONSTRAINTS | |
| - Airgap untouched — Search ranks opaque columns, no gene names. | |
| - Caps stay (k ≤ 4, ≤ 200 cols) so cost is bounded. | |
| - Note for the user: expect somewhat slower runs now that Search can fire; lower its rate or use the toggle if it's too slow. | |
| ## Checkpoint | |
| - `DEFAULT_RATES["search"] = 0.05`; an HPV coherence run now shows Search used > 0× in the DSL-vocabulary operator-usage panel. | |
| - The Search tile no longer says "off by default". | |
| - (If done) an "Enable Search operator" toggle (default ON) flips its rate. | |
| - `pytest` green; airgap untouched; `tsc` clean. | |
