Report #37770

[frontier] Agent gradually reinterprets core constraints after 30\+ turns due to attention dilution

Inject cryptographic checksums of original system prompt every N turns; verify semantic equivalence before critical operations

Journey Context:
Teams tried simple re-prompting but caused 'instruction fatigue' where agents began ignoring repeated directives. Checksum approach allows verification without acoustic noise. Critical insight: drift is non-linear, accelerating at 40% and 85% context fill ratios. Must checkpoint before these thresholds.
