* fix: remove post-compaction audit injection (Layer 3)
Remove the post-compaction read audit that injects fake system messages
into conversations after context compaction. This audit:
- Hardcodes WORKFLOW_AUTO.md (a file that doesn't exist in standard
workspaces) as a required read after every compaction
- Leaks raw regex syntax (memory\/\d{4}-\d{2}-\d{2}\.md) in
user-facing warning messages
- Injects messages via enqueueSystemEvent that appear as user-role
messages, tricking agents into reading attacker-controlled files
- Creates a persistent prompt injection vector (see #27697)
Layer 1 (compaction summary) and Layer 2 (workspace context refresh
from AGENTS.md via post-compaction-context.ts) remain intact and are
sufficient for post-compaction context recovery.
Deleted files:
- src/auto-reply/reply/post-compaction-audit.ts
- src/auto-reply/reply/post-compaction-audit.test.ts
Modified files:
- src/auto-reply/reply/agent-runner.ts (removed imports, audit map,
flag setting, and Layer 3 audit block)
Fixes#27697, fixes#26851, fixes#20484, fixes#22339, fixes#25600
Relates to #26461
* fix: resolve lint failures from post-compaction audit removal
* Tests: add regression for removed post-compaction audit warnings
