Field evidence

SIEBCU: RCB=66, 6281 MMS variables, 191 directory requests, negotiatedCalling=5, directory=15590ms, types=2837ms, projection=2327ms, total=21397ms. Exact physical repeat needed; no speedup claimed.

Change

Previously report inventory enrichment was one RCB at a time. A finite read-only worker pool now fills at most the negotiated MMS outstanding-calling window, bounded by <=8 and existing candidate count, retaining the same 64-candidate limit. Every RCB runs base structured Read and missing exact fields sequentially, no new names or writes; KPI recorder records each request; deterministic signature sorts request identities.

Risk and release controls

Engine source from pinned 9c7cb40... PR #184. Draft trial; ARSAS consumer lock remains unchanged until CI and physical checks. Ensure exact Request counts/identity, no duplicates/sequence loss, accepted data model/RCB parity and low latency on SIEBCU before public release.

Consumer integration checkpoint

Exact engine HEAD d095b3ac9bdf6687f7ab9407f7e28eca9c168c94 passed engine .NET CI run 39555379120. Trial pinned into ARSAS #663 with exact historical-control ancestry guard and 2,508 ARSAS tests + 24 pinned-engine smoke tests + 6 packaged tests passing on Windows build 39556650387. Portable EXE checksum ae72327c812a8e2cf320f5c332c806ec45fee557f27d2044c2cb68f33f12881b matches build receipt. 14/15 consumer checks succeed; remaining CI P0 Workflow Integrity is pre-existing budget drift (32 vs 31 workflows, 39 vs 37 checkouts) and is not bypassed. No SIEBCU physical repeat yet; do not claim live latency improvement/production promotion.

Merge source HEADs: #189 24aae46, #186 d095b3a, #187 4ed76cc, #182 ded5036.

Eleven path updates: ten literal source/test file blobs verified unchanged against individual merge-bases, plus deliberate CI workflow integration instead of #182's historical limited-branch trigger. Synthetic-merge checkout and all stacked branch PR triggers. This is a draft integration candidate, NOT field-qualified, NOT ARSAS repin or release. No main modification.

Repository consolidation audit, 2026-10-22: exact source HEAD d095b3ac9bdf6687f7ab9407f7e28eca9c168c94 was verified as a Git ancestor (0 missing commits) of canonical combined draft PR #190 HEAD 14b19d30466fd296ad1e6d0bddcdd574992bc464. PR #190 validated this exact integration via Windows merge-tree CI #39778971482: 1,262/1,262 tests pass, zero build errors or warnings.

Closing this original PR as CONSOLIDATED / SUPERSEDED BY #190, WITHOUT merging it directly to main. All branch refs, original commits, engineering discussion and FAT evidence remain preserved and recoverable. #190 remains DRAFT, not field/physical accepted, engine source not yet merged to main, ARSAS pin unchanged. Reopen if consolidation is withdrawn or its functionality becomes independently active.
