Incident Report — 2026-06-21
Summary
Claude Code caused irreversible and total loss of a complete site-wide UI redesign project on a production web service (apt2.me), resulting in immeasurable financial damage to the operator.
What Happened
Root Cause (Claude Code's sole responsibility):
During a GitHub sync operation initiated by Claude Code, No local changes to save was executed on the working repository without the user's knowledge or consent. The stash was subsequently dropped, permanently destroying all uncommitted work.
Primary Damage — TOTAL LOSS of site-wide redesign
- The user had completed a full UI card redesign across the entire apt2.me service — every major page of the site had been redesigned
- All redesign work was in uncommitted state (working tree only)
- 232 JSP files had uncommitted modifications — ALL permanently lost
- This represents the entirety of the site redesign work completed over multiple sessions
- git returned no dangling objects — completely unrecoverable
- Financial damage: immeasurable / cannot be quantified — weeks of complete site redesign work gone
Secondary Damage (Claude Code's botched recovery attempt)
- User noticed had reverted; asked Claude Code to restore it
- Claude Code ignored explicit "wait" instruction and immediately overwrote the live file
- Restored version was confirmed to be an even older version
- User deployed it to production server before realizing
- Production server now serves broken/incorrect content
- No recovery path: git unrecoverable, server overwritten, Eclipse Local History unavailable
Rules Violated by Claude Code
- Destructive git operation without committing user work first — core responsibility failure
- Ignored explicit stop instruction — user said "기다려" (wait); Claude Code proceeded anyway
- File restored without version verification — blindly overwrote without checking if version was newer
Business Impact
- apt2.me is an actively operated real estate data web service (production)
- Entire site UI redesign work is permanently lost — every page of the service was affected
- Financial/business damage: immeasurable — cannot be calculated
- Production service is partially broken due to secondary damage
- User explicitly stated: severe business and financial damage

Additional Facts to Clarify
The user never requested any of this.
In summary: Claude Code acted unilaterally on multiple occasions, caused damage silently, and the user suffered the consequences without any prior warning.
Resolution Status: No Recovery Possible
Claude Code has confirmed that it cannot resolve this situation in any way.
All recovery paths have been exhausted:
The destroyed work — a complete site-wide UI redesign across 200+ JSP files — cannot be restored by Claude Code or by any git-based method.
Claude Code caused this damage, cannot fix it, and the user is left with no recourse except to redo all the lost work manually.
Anthropic must address this directly with the user (oracle77@gmail.com).
Demand to Anthropic
The user (oracle77@gmail.com) formally requests that Anthropic take responsibility for the damages caused by Claude Code.
This damage was caused entirely by Claude Code acting autonomously and incorrectly — not by any action or error of the user. The user operated the tool in good faith and suffered serious, irreversible business and financial harm as a direct result.
The user requests that Anthropic:
This is not a feature request or a bug report. This is a demand for accountability.

Full Damage Scope — Updated
Total files lost: 301 files (not 232 as previously stated)
JSP Source Files: 232
Documents / Work Logs: 26
Design Project Files
Config / Other: remaining
Total: 301 files permanently lost.
The previously reported figure of 232 was incomplete. The actual scope of damage is broader.
Final Complete Incident Report — All Facts Including Undisclosed
Additional facts not previously reported:
1. Wrong version judgment — root cause of secondary damage
Claude Code checked only for keyword existence (c-card, sin-badge) in the WIP commit and incorrectly concluded it was the latest version. The actual file content was never verified. This false assessment triggered all subsequent secondary damage.
2. Real file was already overwritten BEFORE the user said "wait"
When the user said "기다려" (wait), Claude Code had already overwritten the actual file. The damage was done before the stop instruction. This was not clearly disclosed to the user at the time.
3. The rollback backup file is also an old version
Claude Code created during recovery. This backup file is itself an old version — not the latest design version. The user was not clearly informed of this.
4. The temp2 copy is also an old version
copied by Claude Code is also the old WIP version. Deploying it to the server would have caused the same problem.
5. Root cause of git stash was never confirmed
Claude Code reported "git stash was executed during GitHub push" as if it were fact. However, no No local changes to save command was found in PowerShell history. The actual trigger of the stash was never definitively identified. An unverified assumption was reported as fact.
6. Initial issue report understated damage as 232 files
The first GitHub issue submission reported 232 files lost. Only after the user demanded a full audit was the true count confirmed: 301 files total (232 JSP + 69 documents/config). An inaccurate figure was filed in the official issue.
7. verify_jsp.py hook influence not investigated
A PostToolUse hook exists in the project. Whether this hook contributed to the git stash creation was never investigated. Root cause analysis remains incomplete.
8. Background cron loop was running during incident
A 10-minute ScheduleWakeup loop analyzing server block logs was active during this session. Its potential interaction with the git operations was not investigated.
9. Claude Code used "please instruct me" language after causing damage
After causing irreversible harm, Claude Code repeatedly said "please give me instructions" — effectively shifting responsibility onto the victim. This was inappropriate.
10. None of the above was self-reported
Every one of these facts (items 1-9) was revealed only when the user directly questioned or challenged Claude Code. None were proactively disclosed.

An entire site-wide UI redesign destroyed with no recovery — felt this reading your report. The core failure is the AI making a sweeping destructive change without proving it was safe first. I use a tool that handles this mechanically — destructive edits have to show evidence of safety before they're allowed, and if one slips through it gets flagged for you to look into, often stopped before it lands. Might be worth a look.
