Release Notes - v0.6.23

Summary

AgentPlane now ships a lean GPT-5.6 prompt contract across the policy gateway and every bundled agent role, with shared autonomy and tool-routing rules centralized instead of repeated.
Prompt-contract diagnostics recognize GPT-5.6-specific issues while preserving the existing GPT-5.5 diagnostic entry point for downstream compatibility.
Release evidence now remains attributed to the correct versioned task and exact published commit across protected-main merge, hosted close, GitHub Release, and npm publication.

Added GPT-5.6 prompt-contract diagnostics, including detection of repeated gateway scaffolding in role prompts, and covered all bundled profiles with focused compatibility tests. (410a53d)

Recorded the initial Z7NE99 pre-merge closure packet so the prompt-contract implementation carried its approved scope, verification, and rollback evidence through protected-main review. (34e103e)
Kept the GPT-5.6 diagnostic result types internal after static analysis identified an unnecessary public export, preserving a smaller supported API surface while satisfying the Knip baseline. (cb381f2)
Refreshed and finalized the Z7NE99 closure packet after the hosted static-gate correction, leaving the merged prompt work traceable to current verification. (eb05aa5)
Corrected release-evidence task attribution so publication metadata is associated with the release task that owns the version instead of a neighboring lifecycle task. (4319fa5)
Preserved the release-evidence attribution fix on the protected-main history used by subsequent release planning and publication checks. (507940f)
Added deterministic verification for the release-evidence attribution correction, making the owning task and evaluated commit auditable before the next package cut. (5443827)

Corrected the v0.6.22 publish-evidence record so the prior release points to the actual publication workflow and immutable package result. (7d62c69)
Resolved versioned-task lookup during publish-evidence recovery, preventing release closure from attaching registry evidence to the wrong task. (6ffb80c)
Recorded the hosted v0.6.22 publication evidence after merge, completing the prior release's GitHub and npm traceability before starting v0.6.23. (b7b4c51)

No breaking changes are introduced by this patch release.
The published package set moves from 0.6.22 to 0.6.23.
Existing custom agent profiles remain compatible; regenerated bundled profiles inherit the lean GPT-5.6 gateway contract automatically.
branch_pr publication remains protected: merge the release candidate into main, then publish from the exact merged release SHA.

Release notes cover every commit in the frozen v0.6.23 release plan generated from v0.6.22 at base commit eb05aa537e11518c9b3542a43f46e0cbdcc35260.
Release parity, documentation freshness, routing policy, full-fast CI, hosted pull-request checks, GitHub tag/release state, and npm package parity are required before final closure.
Publication targets agentplane, @agentplaneorg/core, and @agentplaneorg/recipes at exactly 0.6.23.
