   decide whether the next cut belongs in native capture transport or OCR.
+- **Repeatability and capture-overhead guardrails (2026-07-09)** -
+  `scripts/live-soak.ps1` now writes capture roundtrip and roundtrip-overhead
+  timing into `scan-performance-assessment.json`. The assessment validator can
+  enforce optional speed budgets with `--max-active-average-ms` and
+  `--max-capture-roundtrip-overhead-ms`, and `npm run scan:repeatability:wait`
+  runs 20/45/100 current-engine passes as repeatability evidence without
+  presenting them as an IK comparison. `-RepeatabilityRun` now sets those limits
+  inside PowerShell, and the script refuses unsafe limits above 1800 so npm/cmd
+  argument parsing cannot accidentally turn `20,45,100` into one oversized run.
+- **Distinctive partial piece recovery (2026-07-09)** - a live repeatability run
+  exposed four identical OCR misses where the piece name was read as
+  `Wontiroms Creation pan`. The parser now derives a piece only when a long OCR
+  fragment uniquely matches exactly one known artifact piece. This recovered the
+  local case as `Sharpness That Ceased Upon Wondrous Creation` /
+  `Disenchantment in Deep Shadow` without adding a broad fuzzy exception.
+- **Repeatability live pass after parser fix (2026-07-09)** -
+  `outputs/live-soak/2026-07-09T09-29-11/scan-performance-assessment.json`
+  captured a clean current-engine 20-artifact run: `20/20` parsed, `0` review,
+  `0` misses, `336 ms/artifact` active average, `318 ms` average capture
+  roundtrip, and `138 ms` average roundtrip overhead. The strict 3 artifacts per
+  second budget still failed by 3 ms (`336 ms` vs `333 ms`).
+- **3/s follow-up experiments (2026-07-09)** - tested and rejected several
+  shortcut-style optimizations because live runs got slower or added risk:
+  skipping Paimon-menu analysis, skipping lock-state as a production shortcut,
+  reducing the artifact-level crop scale, and raising the OCR worker pool to 6.
+  The kept low-risk changes are fast-profile OCR crop priority and avoiding a
+  duplicate DataURL string when the native helper already returns Base64. A
+  follow-up clean 20-artifact run after payload cleanup reached `351 ms/artifact`,
+  `331 ms` capture roundtrip, and `146 ms` roundtrip overhead, so the next
