Work interval: 2026-09-27 09:37:27 EDT to 2026-09-27 09:48:44 EDT.

Completed TASK-20260927-42 evidence-only dry-run on rdmsm4x. Fresh Lighthouse succeeded on both ECS sites; no live changes.

• Build rc0: 173 tests/30 suites, app/CLI/helper universal2, minos26.0, explicit ad-hoc signatures. HEAD 91fee4ec991b6cb42cd7c30a497196cd02166ce9, chore/dryrun3-ecs-20260927; source clean.
• Analyze/suggest/apply each rc0 on eastcoastscience.com and eastcoastscience.sh; 12/12 Lighthouse samples successful. .com 8 plans (1 ready, 4 needs connection, 1 blocked, 2 no change); .sh 7 (1/4/1/1).
• Critical CSS BLOCKED with empty changes at 16 KiB; email-obfuscation NEEDS CONNECTION. 30 audit rows, all planned/dryRun, no backupRefs. All 5 real xsite files unchanged by path/size/mtime/hash.
• Files produced: /Users/richh/dev/_handoff/xsite-dryrun3-20260927/PLAN.md, COMMANDS.md, HANDBACK.md, CHANGELOG.md, verify_evidence.py, proof/*; ignored .build and dist under the assigned worktree; scoped ~/.agent-coordination/checkins/codex-rdmsm4x-xsitedry3-20260927.json; ticket progress/final comments.
• Exact executed commands and output/rc/intervals: COMMANDS.md and proof/*.command.txt, *.txt, *.rc, *.times.json. Requested build uses XSITE_SWIFTPM_DISABLE_SANDBOX=1 XSITE_SIGN_IDENTITY=-; analyses use --runs 3 --no-psi; plans have isolated --db/--audit and empty connections.
• Chrome exact-brief preflight rc0; three explicit-profile probes timed out after DOM output and are preserved as diagnostic limitations.
• No site/provider mutation, Keychain value-read command, stable signing, deploy, merge or cleanup. No restore required. Retain evidence and worktree; archive generated proof/build artifacts if retired later, never overwrite original data.
• Ticket ownership/resolution remains shepherd xsite@rdmsm4x/xsite0926. Parent FEAT-20260925-01 stays open. Sites owns future renderer-assisted CSS extraction and live acceptance. No Rich-only action.
• Apple Notes PENDING: this session is Background; helper attempt/receipt recorded in proof/notes-publication.log and .rc. File copies retained in this handoff and canonical changelog archives. The fleet-notes-publish skill says: "In a headless run, write the file copy and report the Notes entry as PENDING". GUI publisher can publish this existing file; no permission workaround.
