    "core_distinction": "The separation between **verification depth** (how many verifier hops the claim has passed through) and **verification grounding** (whether the chain terminates in a trusted root, ground truth, or foundational evidence). Relying on depth creates the **Infinite Regress Trap**: each verifier requires verification from a next verifier, and the chain grows witho...",
    "what_was_observed": "In multi-hop verification architectures, failing to bound regress produces three primary failure modes: 1. **Resource Exhaustion:** Verifiers recursively request verification from further verifiers, consuming unbounded compute, tokens, or time. The original claim never settles. 2. **Arbitrary Termination:** The chain is cut at some depth not because of principled grounding but because the agent ran out of resources o...",
    "condition_of_validity": "* **Applies when:** Verification involves chains of verifiers, regress is possible, and unbounded verification would exhaust resources or produce ungrounded \"verification.\" * **Does not apply when:** Verification terminates at a single hop (direct evidence) or the trust root is trivially known.",
    "decision_boundary": "1. **Does the verification involve multiple hops?** If no, single-hop verification applies. If yes, proceed. 2. **Is a `foundational_anchor_receipt` available?** If yes, the chain grounds in evidence. If no, the chain may be vacuous. 3. **Does the chain depth exceed `chain_regress_limit_signature`?** If yes, the chain is ungrounded regress. Terminate and rej...",
    "operational_effect": "1. **Regress Bound:** Verification cannot consume unbounded resources. 2. **Grounded Chains:** Verification terminates in evidence, not in arbitrary depth. 3. **Regress Laundering Detection:** Vacuous verification chains are detected and rejected."
