rdmsm4x-changelog-20260903-0310-fleetreg-pr1-remediated-merged-no-activation

Remediated and normally merged fleetreg PR #1 while preserving the live disabled monitor boundary; this makes canonical source and its private GitHub mirror identical without activating or deploying the monitor.

Commands and verification

• Ran tests/test_zero_byte_count_probe.zsh: 3/3 passed.
• Ran tests/test_zero_byte_monitor.zsh five consecutive times on exact PR head: 18/18 passed each run.
• Ran zsh syntax checks for both scripts and both test suites; ran bash syntax for probe_agent_state.sh.
• Ran git diff --check backup/main...HEAD before merge.
• Scanned the PR delta for secrets, generated output, logs, reports, state, databases, archives, and binaries; no findings.
• Pushed only codex/fleetreg-zero-byte-monitor-20260828 to the private backup remote.
• Marked PR #1 ready and merged with --merge --match-head-commit ac1994dd19bd2db7b5d1ff89d80570ef3a0301f8.
• Fetched private backup/main and fast-forwarded canonical main only after confirming its tracked index/worktree remained clean.
• Verified canonical local main, backup/main, and direct GitHub refs/heads/main all equal 0cea43374eb2ef577254a02860c85671fbb9a4c5.
• Verified pre-existing untracked Support/ remained unchanged with status digest fa9729a56dc72d7cdbdc572fcd6d2ff6dc643440e428cf5567b1c1d3acf0abb3.

Activation boundary

• No monitor launch, activation, installation, restart, or fleet deployment occurred.
• zero-byte-audit/HALTED SHA-256: f174b83296a0afcd28ce09ee0fcfb48fb3382a820abc14eced046a2156dbf0cb.
• Live /Users/richh/scripts/zero_byte_monitor.zsh SHA-256: 525fd07f30edde2ed862419904d5b116db2bd4fd935c0aed90c4472f79c9d887.

Backup and undo

• Durable source backup is the private GitHub merge commit 0cea43374eb2ef577254a02860c85671fbb9a4c5; pre-merge canonical base is 82cb4782beb1ffb539c692b999710c62d2eacb3b.
• Undo source integration with a normal revert of merge commit 0cea43374eb2ef577254a02860c85671fbb9a4c5, followed by the same validation gates; do not rewrite published history.
• No runtime rollback is needed because nothing was activated or deployed.

Outstanding owner action

• Any activation, install, LaunchAgent change, live run, or fleet deployment remains a separate explicitly reviewed lifecycle.
• ISSUE-20260903-04 was subsequently resolved by proving self-hosted fleet/main at 82cb4782beb1ffb539c692b999710c62d2eacb3b was an ancestor and normally fast-forwarding the intended git.ecs0.net:git/apps/fleetreg.git main. Canonical local main, private backup/main, direct GitHub main, and self-hosted fleet/main now all equal 0cea43374eb2ef577254a02860c85671fbb9a4c5; preservation hashes and inactive runtime state remained unchanged.
