v3.6.9

Added

• Context IR hot-path lineage — Every tool call now records source kind, tokens, duration, and content excerpt into the Context Intermediate Representation for full lineage tracking
• Plugin-ready traits — Extracted CompressionPattern trait (patterns/) and ContextProvider trait (providers/) for future plugin extensibility
• Pytest verbose compression — Dedicated pattern for pytest -v output: consolidates per-test lines, strips fixtures/collection/metadata, preserves tracebacks and test identifiers (#251, contributed by @sisyphusse1-ops)
• Active Context Gate — Pressure-based auto-downgrade: when context utilization exceeds 75%, reads are automatically downgraded (full→map, map→signatures). Φ scores now computed with real task context from SessionState

Fixed

• Workflow persistence blocking reads after crash — Workflows inactive >30 minutes are now auto-expired on load and at runtime. Read-only tools (ctx_read, ctx_multi_read, ctx_smart_read, ctx_search, ctx_tree, ctx_session) always pass through the workflow gate regardless of state
• Misleading cache-hit message — Changed "Already in your context window" to neutral [unchanged, use cached context] with hint about fresh=true for forced re-read. Prevents confusion when server-scoped cache returns hits for files not seen by the current agent
• Unable to clear context pressure (#244) — ctx_ledger(action=reset) now correctly clears all ledger state
• Windows CI CRLF assertion — Normalized line endings in include_str! test assertions
• Flaky CI tests — Serialized environment-variable tests (serial_test), fixed anomaly persistence debounce race, relaxed attention stress threshold for shared runners

Changed

• ARCHITECTURE.md — Fixed documentation drift: updated tool counts, Context IR description, dispatch flow diagram, removed references to non-existent files
• CONTRACTS.md — Restructured as "LeanCTX Protocol Family" with Extension Contracts section for future plugin interfaces
• README.md — Conversion-optimized structure with better hero section, install commands, and social proof

Tests

• 18 new scenario tests for workflow staleness + cache message fixes (bazsi_reported_scenarios.rs)
• 4 new workflow staleness/passthrough tests (workflow_done_scenarios.rs)
• Context IR hot-path recording tests, trait implementation tests, doc integrity tests (hardening_ir_traits.rs)
• Adversarial safety tests for pytest xfail/xpass and test name preservation

Upgrade

lean-ctx update                 # recommended (auto-downloads + refreshes shell hooks)
cargo install lean-ctx          # or
npm update -g lean-ctx-bin      # or
brew upgrade lean-ctx

Note: After upgrading via cargo/npm/brew, run lean-ctx setup to refresh shell aliases. lean-ctx update does this automatically.
