  "source_commit": "COMMIT_CONTAINING_THIS_RECEIPT",
  "trigger": "The sole usable Codex conversation became unable to send messages after continuity guards repeatedly injected session and capsule bodies on prompts, tools, and compaction boundaries.",
  "emergence": "Meta-audit separated the usable HLDP v1 causal folding model from identity binding, lane projection, full-capsule recovery, and fail-closed prompt guards. The replacement is a bounded root, route-then-read traversal, explicit causal leaves, and a SessionStart-only bootstrap.",
  "lock": "Codex continuity uses HLDP v1 bounded recursive causal navigation; no automatic history body injection and no Codex lane prerequisite.",
  "why": "Compression recovery needs the reasons, pivots, rejected branches, invalidation conditions, and source paths required for correct future reasoning; it does not need all prior text in the active context.",
  "changes": [
    "Add the canonical HLDP v1 runtime root and recursive causal memory schema",
    "Add a dependency-free verifier, router, one-node reader, and bounded bootstrap",
    "Route repository entry points from v3/HNL identity loading to the v1 root",
    "Mark v3/HNL and wake-up identity loading as historical material",
    "Document the keep, correct, and retire decisions from the meta-audit"
