DONE condition 6 of GOAL_CUTOVER_READY.md (the EC2 performance measurement) finalized. Same r8g.4xlarge instance, conversation shape, and seed as the pre-vectorization run: cold tick 519.6s → 29.0s (~18x), warm tick 1856.0s → 26.6s (~70x).

  • CUTOVER_RUNBOOK.md risk item 3 now carries the final verdict — serial OK at every observed conversation shape; no blocklisting (none needed); item 9b (seeded sampled PCA for extreme shapes) is now optional — plus the historical measurement chain.
  • GOAL_STATE.md condition-6 line updated.
  • Final battery pair on this tree: the certification battery (20 recorded dataset entries replayed and compared against Clojure reference recordings) at 20/20 MATCH, twice.

…parison, verdict serial-OK

DONE condition 6 of `GOAL_CUTOVER_READY.md` (the EC2 performance measurement) finalized. Same r8g.4xlarge instance, conversation shape, and seed as the pre-vectorization run: cold tick 519.6s → 29.0s (~18x), warm tick 1856.0s → 26.6s (~70x).

- `CUTOVER_RUNBOOK.md` risk item 3 now carries the final verdict — serial OK at every observed conversation shape; no blocklisting (none needed); item 9b (seeded sampled PCA for extreme shapes) is now optional — plus the historical measurement chain.
- `GOAL_STATE.md` condition-6 line updated.
- Final battery pair on this tree: the certification battery (20 recorded dataset entries replayed and compared against Clojure reference recordings) at 20/20 MATCH, twice.
