B3-F1c-g dot-dot-health Scheduler Repair — ROLLBACK Artifact

Mode: COMPILE ROLLBACK ONLY (no execution) Target file: web-test/dot/bin/dot-dot-health Companion patch: p3d-birth-b3f1c-g-dot-dot-health-scheduler-repair-patch.md Pairs with: Hunk 1 (parse_args no-op) + Hunk 2 (safe source guard)

---

1. Rollback Strategy

Two independent rollback paths, in order of preference:

#	Strategy	When to use	Reversibility
R1	Restore from timestamped backup (.bak.b3f1c-g.<ts>)	Default — backup made at apply time	Instant, byte-perfect
R2	Reverse-apply unified diff	Backup missing or corrupted	Surgical, requires diff tool
R3	Git revert	If commit was made and pushed	Standard git flow

---

2. R1 — Restore from backup (RECOMMENDED)

The patch apply procedure (§6 of patch artifact) creates:

/opt/incomex/dot/bin/dot-dot-health.bak.b3f1c-g.<UTC-timestamp>

Rollback command:

cd /opt/incomex/dot
# Identify the backup (most recent matching pattern):
ls -lt bin/dot-dot-health.bak.b3f1c-g.* | head -1
# Replace live with backup (USER ACTION — not executed by drafter):
cp bin/dot-dot-health.bak.b3f1c-g.<UTC-timestamp> bin/dot-dot-health
# Verify byte-perfect restore:
sha256sum bin/dot-dot-health bin/dot-dot-health.bak.b3f1c-g.<UTC-timestamp>
# Two hashes must match.

Verification after R1:

bash -n bin/dot-dot-health                              # syntax OK
grep -n 'main "\$@"$' bin/dot-dot-health                # bare main "$@" restored
grep -nE '--local|--cloud' bin/dot-dot-health           # no-op cases gone

---

3. R2 — Reverse-apply unified diff

If R1 unavailable, apply the inverse of the patch:

Apply with:

# Save the diff above to /tmp/b3f1c-g-rollback.diff, then:
cd /opt/incomex/dot
patch -p1 < /tmp/b3f1c-g-rollback.diff

---

4. R3 — Git revert (if patch was committed)

cd /opt/incomex/dot                       # or appropriate repo root
git log --oneline -- bin/dot-dot-health | head -5
# Identify the B3-F1c-g commit SHA, then:
git revert --no-edit <SHA>
git commit --amend -m "revert: B3-F1c-g dot-dot-health scheduler repair (rollback)"

⚠ Per memory feedback_git_commit_after_vps_edit.md: if rollback edits the VPS-host copy of /opt/incomex/dot/bin/dot-dot-health directly, follow up with cd /opt/incomex/dot && git add -A && git commit to keep the VPS repo state consistent. Per memory project_agent_data_repo_diverged.md, never git pull on diverged VPS repos; edit host directly.

5. Independent partial rollback

Each hunk is independently revertible if only one needs to be undone:

Revert Hunk 1 only (keep safe source guard, drop --local no-op):

6. Post-rollback verification (NON-MUTATING)

After any R1/R2/R3:

Check	Command	Expected
Syntax	bash -n bin/dot-dot-health	exit 0
Bare main present	grep -n '^main "\$@"$' bin/dot-dot-health	1 match (last line)
No-op cases absent	grep -nE '\-\-local|\-\-cloud' bin/dot-dot-health	only Usage: lines
Source guard absent	grep -n 'BASH_SOURCE' bin/dot-dot-health	line 26 only (SCRIPT_DIR)
--help non-mutating	bin/dot-dot-health --help	usage banner, exit 0

No mutating verification (no bare execution, no cron retrigger). If cron behavior must be re-validated after rollback, schedule a dedicated session.
