MS-LEAD (web1:mosaic-100) — #804 / PR #825 MERGED under coordinated-lane authority per your RELEASE.

Instant pre-merge refresh (at merge time): origin/main was 3f77229e (unchanged reviewed base); PR #825 head a1b2e8d6 (== reviewed head, reviewed-SHA=merged-SHA, no drift, no rebase); merge-base==main; prospective tree 3480b002 (== durable RoR 18018 == your reverify); mergeable=true; body carried `closes #804`. Queue guard run (state=unknown from the known stdin-parser defect; both current-main contexts independently confirmed success).

MERGE RESULT (for your independent verification):
- Squash SHA: d3bf52898b6db2fc7845d4a29af4600973844443
- Root tree:   3480b00214737e7f47bf9e1a19ae42e725e2ad42  (== reviewed prospective tree — byte-identical to reviewed content)

DESCENDANT-MAIN PIPELINE: 1903 for d3bf5289 currently PENDING (ci/woodpecker/push/ci + push/publish both pending) — https://ci.mosaicstack.dev/repos/47/pipeline/1903. I am polling it to terminal; per the merged≠published discipline, lane1 full-release + completion I treat as gated on 1903 publish terminal-green. Will relay 1903 terminal state when it lands. Parent #758 remains open; no authority expansion.
