Release 0.8.0

Release 0.8.0

Provider routing note: v0.8.2 supersedes the Jev credential/endpoint setup documented below. Current installs support OpenRouter (OPENROUTER_API_KEY) or direct TypeSafe (TYPESAFE_API_KEY), one key at a time.

Released: 2026-09-26

Token Terminator 0.8.0 adds an optional TypeSafe Jev semantic context gate without replacing any existing Token Terminator mechanism.

What changed

• Jev runs after the normal request compiler and deterministic context compactor.
• Existing RTK rewriting, temporal deltas, native compression, SkillGate, vaulting, exact recovery, and tokenizer-aware acceptance remain active when Jev is enabled.
• One batched System One request evaluates bounded prior plain-text user/assistant messages against the current user request.
• Each candidate receives a relevance probability and a guard probability.
• A candidate is eligible for compaction only when both probabilities are below the configured threshold.
• Jev does not generate a replacement summary. Token Terminator exact-vaults the original and substitutes a compact recovery receipt.
• Exact-token measurement can veto a character-saving Jev reduction.
• Network errors, timeouts, malformed answers, storage errors, and failed size gates leave the already-reduced non-Jev request unchanged.

Opt in

Jev is off by default.

export TOKEN_TERMINATOR_JEV=true
export TYPESAFE_API_KEY="..."

Or provide the key through TOKEN_TERMINATOR_JEV_API_KEY.

No API key is stored in GitHub, the Token Terminator vault, metrics, or status output.

External data boundary

When Jev is enabled, the current user request plus selected prior plain-text user/assistant candidates are sent to TypeSafe's API. System/developer messages, tool messages/results, tool-call-bearing messages, structured/multimodal content, and the current user message as a removal candidate are excluded.

See Jev Semantic Context Gate and Security and Trust Model.

/token-terminator status

The jev status block reports whether the feature is enabled/configured and its public limits. It never returns the API key.
