-## External quality-eval fixtures
-
-The public Live benchmark can execute a fixture owned by another repository
-without copying its task corpus or rubric into Impeccable:
-
-```sh
-bun run bench:live -- \
-  --fixture-dir=/absolute/path/to/private-fixture \
-  --agent=codex \
-  --action=bolder \
-  --iterations=1 \
-  --evidence-bundle=/absolute/path/to/output-bundle
-```
-
-An external fixture has the same shape as a directory in this folder:
-`fixture.json`, `gitignore.txt`, and `files/`. Use the optional
-`evidenceCapture` block in `fixture.json` for rubric-free capture metadata:
-
-```json
-{
-  "evidenceCapture": {
-    "captureSelector": "section.case-study",
-    "mode": "target",
-    "viewport": { "width": 1440, "height": 1080 },
-    "action": "bolder"
-  }
-}
-```
-
-Use `"mode": "target"` when `captureSelector` is the picked element itself;
-the original resolves through that selector and each variant resolves through
-its exact Live wrapper. Omit it when the selector is a stable ancestor used as
-shared page context for every capture.
-
-The bundle contains `report.json`, the original capture, each progressively
-delivered variant capture, geometry/overflow facts, hashes, and timing data.
-It deliberately cannot run `--judge-rendered`; comparative rubrics, private
-fixtures, human calibration, and quality decisions belong in the consuming
-evaluation harness. The normal public E2E suite remains responsible for Live
-protocol, framework, source-commit, cleanup, and recovery correctness.

-# Live cross-provider benchmark
-
-This benchmark compares Live variant delivery strategies without confusing model latency with browser/poller overhead. It uses the realistic `vite8-react-brand-fidelity` fixture and scores every output with deterministic gates for:
-
-- brand fidelity;
-- component fidelity;
-- CSS-token fidelity;
-- exact copy fidelity;
-- source/schema validity;
-- provider-independent Accept cleanup and production build validity.
-
-The model matrix and the cleanup control are intentionally separate. Provider generation runs use a fixed synthetic picker event. The cleanup control runs a real Vite/React Live session in Playwright, accepts variant 1, waits for Pick mode, checks that Live markers are gone, and builds the accepted source. This prevents a provider from being blamed for local publisher/poller behavior while retaining a real pipeline safety gate.
-
-## Commands
-
-Validate the matrix without API or browser calls:
-
-```sh
-npm run bench:live:providers -- --dry-run
-```
-
-Run the recommended small matrix and write a report:
-
-```sh
-npm run bench:live:providers -- \
-  --strategies atomic-full,progressive-compact,parallel-compact \
-  --iterations 1 \
-  --output artifacts/live-provider-benchmark.json
-```
-
-Run only the real Accept/build cleanup control:
-
-```sh
-npm run bench:live:providers -- --cleanup-only --output /tmp/live-cleanup.json
-```
-
-Arguments accept either `--name=value` or `--name value`. No output file is created unless `--output` is supplied. API keys load, in order, from `--env-file`, the repo `.env`, and `~/code/impeccable-evals/.env`; reports include only key availability, never key values.
-
-## Strategies
-
-- `atomic-full`: one call generates all variants with the full Live reference. This is the latency and cost control.
-- `progressive-full`: a first-variant call followed by a remaining-directions call, both with full Live context.
-- `progressive-compact`: the same split with the stable compact producer contract. Variant 1 and its CSS segment are carried forward byte-for-byte and assembled locally.
-- `parallel-compact`: three compact one-variant producers run concurrently. The first valid result is reviewable immediately; centralized assembly remaps the other CSS scopes deterministically.
-
-The earlier idea of asking the second progressive call to reproduce variant 1 is deliberately excluded. It adds tokens, permits drift, and conflicts with transactional source publication. Deterministic assembly is the production candidate.
-
-## Interpretation
-
-A run passes only when overall fidelity is at least `0.90`, every dimension is at least `0.75`, and the real cleanup control passes. One iteration is a smoke matrix, not a statistically stable claim; use at least five iterations before setting a release threshold.
-
-Cost estimates use provider-reported token counts and standard per-million-token prices recorded on July 11, 2026. Update `PROVIDER_PROFILES` when model pricing changes. Price sources are embedded in every report.
-
-Latency runs use low effort for Claude Sonnet and GPT, and Gemini 3.1 Flash-Lite's minimal-thinking default. These settings are emitted in provider metadata so a report cannot silently compare different reasoning budgets.
