ContextLattice v3.8.0

Release date: 2026-07-01

v3.8.0 moves the gateway to the MongoDB Go driver v2 line and adds the Context Pack Quality Ledger: a bounded telemetry layer that separates exact prompt-token savings from confidence-banded inference avoidance.

Highlights

  • Migrates the Go gateway from go.mongodb.org/mongo-driver v1 to go.mongodb.org/mongo-driver/v2.
  • Adds /telemetry/context-pack-quality for context-pack quality, exact prompt savings, modeled inference avoidance, and outcome calibration.
  • Adds /telemetry/context-pack-quality/outcome so agents can post compact first-pass, repair, retry, and follow-up-token outcomes.
  • Persists compact bounded quality rows without raw prompts, raw queries, or recalled source text.
  • Adds context_pack_quality to context-pack responses with a sample id, query hash, quality score, counterfactual baseline, and confidence-banded modeled inference tokens avoided.
  • Updates the dashboard cockpit with a separate modeled inference avoided metric so exact prompt-token savings are not mixed with counterfactual estimates.

Measurement Contract

v3.8.0 deliberately keeps two claims separate:

  • Exact prompt-token savings: measured from tokenizer-aware context-pack token deltas.
  • Modeled inference avoidance: confidence-banded estimate of extra retry or repair calls avoided by a better context pack.

The modeled value becomes stronger only when outcome rows are posted. Until then, the API marks it as modeled_counterfactual rather than exact.

Storage Contract

The quality ledger is designed for low data volume:

  • Bounded NDJSON storage.
  • Byte and sample caps.
  • No raw prompt text.
  • No raw source text.
  • Query provenance is stored as a hash only.
  • Public storage status exposes durability, caps, loaded rows, parse errors, write errors, and sanitized error codes.

Verification

  • Gateway tests passed for MongoDB driver v2 migration, tokenizer-exact token impact, context-pack quality ledger persistence, outcome calibration, and native route ownership.
  • Dashboard tests passed for exact token impact and context-pack quality parsing.
  • Dashboard production build passed.
  • Release-note hygiene passed for these notes.

Upgrade Guidance

Use v3.8.0 for new installs and upgrades from v3.7.x. No migration is required for the local token-impact ledger. The new context-pack quality ledger starts collecting compact rows when context packs are generated.
