REPORT — 2026-09-25 evening: docmost's PostgreSQL 16 → 18, the harness converts, the gate lets one app through

• Harness v4 (6a4a5f0, 7036119 dump fix): a PostgreSQL major is converted on the bench the box's way; render and --write-ladder move a PostgreSQL 18 data mount to /var/lib/postgresql; --write-ladder writes engine_conversion only when BOTH venues converted it. test_pg_conversion.py (10 checks).
• check-engine-major.py: a PostgreSQL major passes only with its proven, two-venue, marked ladder entry, alone in its commit; the postgis family is judged now. Decoys: 1 genuine, 5 refused (no mark, one venue, the mark in a comment, bundled, postgis) — red-proofed (felhom.eu/documentation/audits/night-2026-09-26/C/C2-*).
• docmost moved (afd3a60): postgres:16-alpine → postgres:18-alpine, mount moved, engine_conversion written by the harness. Bench (throwaway LXC 9401, destroyed): converted in 11.0 s, check equal over 48 tables, seed read back, 0 kills; negative control C3 → failed. Box: 9202 through the product (see the controller REPORT). docmost's own limit 384M → 512M (09 §3 decision 39): the watch measured 91 % at 384M and 80.4 % at 512M — Node sizes its heap from the limit (R-693). The Hungarian prerequisite line changed with it; copy_freeze updated on purpose (the gate caught the first push).
• nextcloud after_load: php occ files:scan --all (9cc829c, the Part E helper): a file written after the last backup is invisible after a load until the rescan (measured).
• Not moved: adventurelog v0.13.0 (R-655) — its SKIP_WORLD_DATA=1 switch and the cached dataset file are now measured; the move needs a choice between the two options written in the row.
