benchmarks/gaia2 — Gaia2 ARE setup + GEPA dry verification

Stream: CC Sesija C (Track D in pre-launch sprint consolidation 2026-04-30). Brief: D:/Projects/PM-Waggle-OS/briefs/2026-04-30-cc-sesija-C-gaia2-setup-dry-verification.md (LOCKED). Branch base: phase-5-deployment-v2 (PM ratification 1B; per LOCKED branch architecture 2026-04-30 §2 — Phase 5 baseline = gepa-faza-1 6bc2089, deployment branch tip a8283d6). Scope: ARE platform install + Gaia2 dataset adapter + GEPA-evolved variant dry verification (4 shapes × 10 tasks subset of Search split N=200) + ERL methodology integration plan. Cost cap: $20 hard (retroactive amendment 2026-04-30, was $15) / $8 halt-trigger γ probe (PM ratification γ — first batch as probe).

STATUS: Phase 3 CLOSED 2026-04-30 — Sesija C STANDBY pending Phase 4 setup

Re-framed deliverable scope (per probe-validated reality):

✅ Pipeline integrity verification — adapter contract works end-to-end on real Gaia2 schema (dry-run-results-memo.md §5).
✅ Cost reconciliation methodology — paper estimate 9–31× under-shot probe-validated reality; root cause: anchor-then-multiply input-size regime gap (feedback_anchor_multiply_input_size_regime memory).
✅ GEPA shape routing OOD verification — Phase 4.5 mechanism activation visible on Gaia2 even on halted runs; arxiv §5.4 evidence (project_gepa_ood_arxiv_evidence memory).
✅ Schema fixes documented + committed — JSON-string data parse, apps-as-array, USER-event extraction, ASCII-only headers.

Real evaluation deferred to Phase 4 Docker — narrow-proxy economics non-viable ($163.77 projected for full sweep, 11× cost cap); ARE-native targeted tool calls in Docker bypass the bulk-retrieval driver entirely (~160× input-volume reduction projected).

NOT done in Sesija C, queued to Phase 4 kickoff or post-launch Phase 3 sprint:

Task C5+C6 — full N=40 dry run (Phase 4 pre-flight; 4-invocation probe was the Phase 3 substitute).
Task C7+C8 — ERL methodology integration plan (erl-integration-plan.md not authored).
Task C9+C10+C11 — cost validation + dry-run results memo + final commit (closure stamped in dry-run-results-memo.md §9 instead).
Phase 4 Docker / WSL / Linux runner host choice + Phase 4 budget allocation.

Cumulative Sesija C spend: $16.38 of amended $20 cap. Headroom $3.62.

External dependency

ARE platform installed at D:/Projects/waggle-os/external/meta-agents-research-environments/ (Phase 2, Task C1).

Repo: https://github.com/facebookresearch/meta-agents-research-environments (MIT).
Pinned upstream SHA (verified via git rev-parse HEAD post-clone): 0330191ffef8581e3c0620b78df9c7408bcb98b0 (2026-04-20).
Dataset: HuggingFace meta-agents-research-environments/gaia2 (CC-BY-4.0); 800 scenarios across 6 configs (search/execution/adaptability/time/ambiguity/mini, 200 each).
Install method: uv sync --frozen (verified — 95 deps, ~1.5min, exit 0). uv-managed Python 3.10.18.
Smoke verification: benchmarks/gaia2/smoke-evidence.md (Phase 2 deliverable). Windows compat: SIGALRM blocker in scenario timeout enforcement → Phase 4 host choice (Docker/WSL/Linux) deferred to PM.
