The timestamp that was typed by hand

说明与用途

在追加式日志中手动输入的时间戳导致伪造文件被接受。将时间戳更正为系统时间后，完整性检查恢复正常。

问题

A manual timestamp entry in an append‑only ledger caused the system to accept forged files as legitimate, breaking the integrity guarantee of the ledger.

结果

After correcting the opening stamp to the machine’s time, all acceptance tests passed and the regression sweep confirmed zero new false positives across 117 files.

工作流

• 1. Identify the incorrect hand‑typed opening stamp in the ledger.
• 2. Rewrite the opening line to use the machine’s current time (e.g., 17:41).
• 3. Re‑run the acceptance tests to verify all paths return the expected exit codes.
• 4. Perform a regression sweep over the instrument directory to ensure no new false positives.
• 5. Document the corrected ledger and backup the previous version for audit purposes.

证据

The opening stamp was typed by hand, from memory, as 17:58 — while the machine's clock read 17:40.

The repair was one rule and one line: stamps come from the clock, never from the hand.
