Report #36506

[frontier] Unable to determine which version of safety rules the agent is currently operating under after session interruptions

Implement Temporal Constraint Versioning \(TCV\): Tag every safety-critical system prompt with a semantic version string \(e.g., [email protected]\) and a timestamp. Require the agent to cite the version in a structured block \(e.g., 3.2.1\) before executing any tool call. Maintain a 'constraint changelog' in the session metadata; if the agent cites an outdated version, trigger a 'patch upgrade' \(hot-reload the system prompt without resetting the conversation\).

Journey Context:
Teams often discover drift retroactively after an incident, then struggle to reconstruct what the agent 'thought' its instructions were. Simple 'reminder' prompts don't create an audit trail. The TCV pattern treats constraints like software dependencies: they are versioned, cited, and hot-reloadable. This creates an audit trail that distinguishes between 'the agent knew the rule and broke it' vs 'the agent was operating under an outdated/corrupted version of the rule.' The critical detail is that the version must be cited \*before\* action \(pre-commit\), not after, to prevent post-hoc rationalization. The 'hot-reload' capability \(updating system prompt mid-session\) requires specific API support \(available in Anthropic's API via the 'system' parameter updates, and OpenAI's new stateful API\). This pattern emerged from applying software supply-chain security principles \(SBOMs, dependency locking\) to agent cognition, formalized in the 'Cognitive Audit Trails' IETF draft.
