ContextLattice v3.19.0: The Delta and the Proof

Context should move at the speed of the work, not drag its entire history behind it. ContextLattice v3.19.0 gives agents the exact delta when the delta is trustworthy, then gives operators one integrity-checked chronology of what the run actually knew, did, corrected, verified, and learned.

The CLI remains the primary interface. HTTP remains the integration fallback.

What ships

  • Digest-verified Agent Packet deltas with explicit base acknowledgement, canonical ordered operations, tombstones, exact reconstruction proof, and safe full-packet fallback.
  • A unified proof timeline over authoritative session, continuity, claim, outcome, context-quality, and token-impact ledgers. Missing, corrupt, cross-scope, concurrent, and retention-truncated evidence remains an explicit gap.
  • Bounded proof accounting and redaction that keeps raw prompts, credentials, personal paths, and private memory out of transported evidence.
  • Bounded, lossless session identifiers, uniform absent-selector handling, and request parsing that does not silently create or reuse the wrong session.
  • Runtime audits bound to the exact source identity and process boot, so a fresh but unrelated runtime cannot satisfy release proof.

Public core

The public lane includes deterministic delta negotiation and reconstruction, the local proof timeline, the primary CLI workflows, exact fallback behavior, and the security boundaries required to trust them. It does not require a paid key, provider inference, a Python application service, or a new MCP tool.

Public-paid

The paid lane adds governed cross-machine packet retention, signed delivery receipts, acknowledgement-before-base advancement, shared workspace proof timelines, retained analytics/export, explicit deactivate and rollback controls, and entitlement-bound mutation.

Measured result

The frozen Agent Packet holdout reconstructed the same model-visible context in every accepted delta and rejected unsafe bases with a full fallback. In the release-candidate evaluation, 5 of 19 cases produced useful deltas, 11 exercised safe fallback, and exact serialized transport accounting saved 3,033 o200k_base tokens without provider or external-network calls.

The proof-timeline holdout passed 15 of 15 adversarial chronology cases with zero silent gaps, redaction failures, authoritative-ledger mutations, provider calls, or external-network calls. Shared-retention proof now runs three independent 24-write fsync bursts: all 72 writes and concurrent reads must succeed, the median batch p95 must stay below 250 ms, and at least two of three batches must clear the threshold.

Windows artifacts are cross-compiled and build-verified; native Windows execution remains explicitly unproven for this release.

Rollback

  • Disable delta packets to return immediately to full Agent Packets.
  • Disable proof-timeline projection to return to the existing session trace.
  • Stop paid shared-retention automation without deleting authoritative packet, session, claim, outcome, or token ledgers.

Rollback removes projections and automation. It never rewrites the evidence they were built from.
