4. Patch application

Method: Anchor-based string replacement via Python 3 on VPS, atomic write via os.replace after os.chmod to preserve mode 0755.

Hunk 1 — parse_args no-op insertion

• Anchor: contiguous text ' ONLY_CHECK="$2"; shift 2 ;;\n *)\n log_err "Unknown option: $1"\n'
• Uniqueness asserted: count == 1 in source. PASS
• Inserted line (between anchor before/after):

        --local|--cloud)       shift ;;  # no-op: legacy DOT scheduler convention (env loaded from SSOT, Đ33 §14)
  

Hunk 2 — Safe source guard at file tail

• Anchor: file ends with '}\n\nmain "$@"\n'
• Uniqueness asserted: count == 1 AND content.endswith(anchor). PASS
• Replaced final 3 lines }\n\nmain "$@"\n with }\n\nif [[ "${BASH_SOURCE[0]}" == "$0" ]]; then\n main "$@"\nfi\n

5. Non-mutating verification (V1–V6)

V1 — bash -n /opt/incomex/dot/bin/dot-dot-health

Exit 0, no output. ✅ PASS

V2 — Static parse_args range

sed -n 165,182p shows the new case correctly placed between --only-check and *):

      --only-check)
        [[ $# -lt 2 ]] && { log_err "--only-check requires value"; exit 2; }
        ONLY_CHECK="$2"; shift 2 ;;
      --local|--cloud)       shift ;;  # no-op: legacy DOT scheduler convention (env loaded from SSOT, Đ33 §14)
      *)
        log_err "Unknown option: $1"

Grep ^\s+--local\|--cloud\)\s+shift ;; returned exit 0 (1 match). ✅ PASS

V3 — Static BASH_SOURCE guard at file tail

tail -6 shows:

  exit 0
}

if [[ "${BASH_SOURCE[0]}" == "$0" ]]; then
  main "$@"
fi

Grep BASH_SOURCE\[0\].*\$0 matched at line 556. ✅ PASS

V4 — Bare main "$@" absent

grep -nE '^main "\$@"$' returned exit 1 (0 matches). ✅ PASS

V5 — --help (proven non-mutating)

$ /opt/incomex/dot/bin/dot-dot-health --help
Usage: dot-dot-health [OPTIONS]
…
EXIT CODES:
  0  OK (healthy OR warn-only)
  1  FAIL (ít nhất 1 critical fail)
  2  USAGE
  3  PRECHECK_FAIL

Exit 0. Code path: main → parse_args → --help|-h match → usage; exit 0 (terminates BEFORE precheck/env_load/run_pg_rw/log_issue). ✅ PASS

V6 — --local --help (validates H1 no-op + non-mutating)

$ /opt/incomex/dot/bin/dot-dot-health --local --help
Usage: dot-dot-health [OPTIONS]
…

Exit 0. Code path: main → parse_args → 1st iter matches --local|--cloud) shift → 2nd iter matches --help|-h) usage; exit 0. Validates both that --local is now silently accepted (no Unknown option: --local log_err) AND that the rest of the parser continues. ✅ PASS

All 6 verification checks PASS. No mutating verification performed (bare invocation and --dry-run excluded per hard boundaries).

6. VPS-host git commit

Per memory feedback_git_commit_after_vps_edit.md: every VPS edit must be git commited.

cd /opt/incomex/dot
git add bin/dot-dot-health        # specific file only — other dirty files belong to other sessions
git commit -m "fix(dot-dot-health): accept --local/--cloud no-op + safe source guard (B3-F1c-g)"

Field	Value
Repo	/opt/incomex/dot
Branch	main
Commit SHA	bd2588a8ae1ebf72c51d9ab0da9cac13aa6a7c8f
Stat	1 file changed, 4 insertions(+), 1 deletion(-)
Committer	root <root@vmi3080463.contaboserver.net> (auto-configured)
Author identity warning	Informational only; not corrected (hard-boundary "NEVER update the git config" honoured)
Other dirty files in repo	dot-birth-trigger-setup, dot-context-pack-build.sh, dot-vector-audit (modified by prior sessions, NOT committed by this session); dot-search-canary, specs/ (untracked, NOT staged)

No git pull performed (per memory project_agent_data_repo_diverged.md and general "no destructive ops" guidance — though this is a different repo from agent-data-repo, the same prudence applies on VPS-host repos).

Expected next event	03:00 UTC daily cron tick will now pass --local and run full health checks; previously was failing with exit 2 at parse_args

8. Rollback availability

✅ Available via any of the 3 paths from the rollback artifact:

• R1 (recommended): cp -p /opt/incomex/dot/bin/dot-dot-health.bak.b3f1c-g.20260514T061811Z /opt/incomex/dot/bin/dot-dot-health → re-hash should match b9a623ab…
• R2: reverse-apply unified diff from rollback artifact §3
• R3: cd /opt/incomex/dot && git revert --no-edit bd2588a8ae1ebf72c51d9ab0da9cac13aa6a7c8f

---

9. Observation plan (read-only, deferred)

Next natural validation: 03:00 UTC cron tick (~21h from execution time 06:18 UTC 2026-05-14). Read-only observation only:

# Run via SSH; do NOT manually trigger the script.
tail -n 200 /var/log/incomex/dot-health.log    # check most recent run
journalctl --since "today 03:00" | grep -i dot-health

If 03:00 cron tick produces [OK] rollup with no Unknown option: --local error, B3-F1c-g end-to-end is validated. If unexpected output, R1/R2/R3 rollback is immediately available and clearly documented.

No automatic monitoring scheduled in this session — observation deferred to next user-initiated check or B3-F1c completion gate.
