v1.9.0

[1.9.0] — 2026-06-12

Added

• Model-family acceptance release gate: manifest-driven all-family strict acceptance for basics, discrete, continuous, hierarchical, multi-agent, precision, structured, gridworld, and scaling-study fixtures.
• Cross-step evidence ledger: release ledger now links Step 3/5/6/11/12/15/16/23 statuses, artifact links, telemetry presence, renderer/execution status, and concrete skip reasons per family.
• Interpretability summaries: per-family summaries now include variable/edge inventories, matrix-shape tables, telemetry presence, optional trace previews, renderer/execution status, and artifact links.

Changed

• Continuous and hierarchical Step 11/12 outcomes are explicit profiled unsupported skips with concrete reasons, not raw render/execute failures accepted by profile math.
• v1.7.0 is retired as a foundation-only track; unfinished runtime-depth ambitions move forward into v2+ reliability and orchestration milestones.
• Current test evidence updated to 2,399 collected tests; final full-suite release evidence is recorded in TO-DO.md, README.md, and test documentation after the v1.9 release gate rerun.

Fixed

• Removed the model-family acceptance reason-pattern fallback that could reclassify failed renderer/executor steps as unsupported success.
• Hardened strict acceptance so profiled unsupported steps must be skipped before execution and failed Step 11/12 summaries fail closed.
• Prevented cross-framework analysis from reading stale repo-tracked output/ artifacts during isolated /tmp acceptance runs.
• Relaxed an environment performance smoke threshold to match other slow module smoke tests and avoid full-suite load false negatives.

Validation

• PR #12 checks passed: Bandit, CodeQL, analyze (python), dependency-review, markdown-audit, security, test (3.11), test (3.12), test (3.13).
• Local full suite: 2381 passed, 17 skipped, 1 xfailed with Ollama integration tests ignored.
• Local collect-only: 2,399 collected tests with Ollama integration tests ignored.
• All-family strict acceptance: passed for 9 manifest families; continuous and hierarchical Step 11/12 are explicit profiled unsupported skips with concrete reasons and no raw failed Step 11/12 counts.
