Problem

BraceCase agent corrupted 203 files by appending orphan closing delimiters (}, ), ]). Initial remediation underreported scope by 8x (25 vs 203 files). Build was completely broken with 1,334 TypeScript errors. Question: rollback to pre-BraceCase baseline vs fix in place?

Resolution

Answer: Rollback loses 28 days of work (221 commits). Unnecessary—corruption fixed surgically.

Changes

Corruption fixes (202 source + 1 test file)

  • Removed trailing orphan delimiters from end of files
  • Preserved all code logic, no functional changes
  • Pattern: lines with only }, ), or ] after valid code

Verification

  • Build: 1,334 errors → 0 (263 JS files generated)
  • Tests: 399/405 passing (failures pre-existing)
  • All engines, tools, services operational

Documentation (docs/BRACECASE_POSTMORTEM.md)

  • Corrected scope: 25 → 203 files
  • Severity: High → CRITICAL
  • Added incomplete remediation timeline and lessons learned

Rollback Impact Analysis

Rolling back to commit 20724ba (Jan 11, 2026) would:

  • Lose 221 commits spanning 28 days
  • Require 40-60 hours manual cherry-picking
  • Risk introducing new bugs
  • Discard already-fixed corruption

Current state eliminates need for rollback. All legitimate development work preserved.
