Supplementary analysis, not a new decision: exp-003's verdict stands.
The 142 units excluded for an uncached response were filled with the same
six incumbent programs, parameters and request keys, on exp-003's
937-example memory (the harvest's 196 rows and its 2026-10-03 embeddings
left out; a zero-cost replay first reproduced exp-003 exactly: 211
decided, 1056 replayed, $0.582876). Fill: MeteredClient, ceiling $0.99
under the approved $1.00, 697 client calls, $0.331759, no provider error.
Replay on all 353 units (244 paired, 146 groups): 0 client calls, $0.0,
1768 responses replayed; no arm flags any unit, the registered rule reads
inconclusive. Calibration holds only for untrusted destination (ECE
0.0454) and arm A still finds no BLOCK point there.

Zero-cost replay of the six slice-2 programs: meter 0 client calls, $0.0;
211 of 353 units scored, 142 excluded for an uncached response (path lost
all 39). Arm A (calibrated) fails calibration (ECE 0.077 access control,
0.1067 injection); arm B (Wilson LB >= 0.95, nested) chooses no threshold on
any fold, as the registration's power note predicted (73 clean flags needed,
38 paired injection positives); secondary arm C flags nothing either. The
instrument check shows real scores; the zero is the rule's.

Registered in s3://sast-memory at dd7ebc1: manifest 5917f9a1, units 338de998
(353 units, 146 groups). Primary metric, decision rule and the threshold
selection are fixed in the manifest; the power note says arm B cannot reach
a Wilson LB of 0.95 on this data (73 clean flags needed, 38 paired
positives at most).

Reject B. 160 paired units (injection 119, access_control 41; 56 repositories),
both arms, two replicates each, no early stop. Canary agreement A 0.875 -> B
0.906 (CI [-0.03, +0.10], spans; B meets 0.90). Within-pair AUC A 0.815 -> B
0.741 (CI [-0.13, -0.02], against B). AUC -0.02 (against), ADVISORY recall
-0.06 and precision +0.01 (span), usd per candidate A $0.0021 -> B $0.0051
(against). Priced usage A $0.68 / B $1.63; balance $16.72 -> $16.04 at the
run's end (lags). Counts only; task 7.4 marked done.

The experiment row in s3://sast-memory now carries units_digest 0de66bfa... at
pin 9213e5f (manifest digest unchanged, f5004fb8...). Counts per family and the
two repairs the freeze needed are in the record; no model.

Registration rows at pin fbc3220 in s3://sast-memory; in-repo records under
benchmarks/experiments/<id>/registration.json. exp-002's units could not be
frozen: every example row in the store carries null plane-only instruments
and learn.examples.load_examples raises on them (unchanged code since
a90e570) -- a store-side change to diagnose before any paid run.
