Summary

Fixes evolution-memory curation failures caused by inconsistent placement semantics.
Aligns the curator, writer, proposal schema, and runtime correction behavior.

Reasoning

The public contract and writer already treated a null/null ADD destination as global append, but the curator rejected it.

REPLACE also reused ADD placement after removal, which relocated replacement content.

Semantic validation ran outside the active model transcript, while the schema and exhausted-response classification disagreed with parser and request-stage behavior.

Changes

• Accept and document null/null global append placement.
• Make REPLACE preserve the original item and section location.
• Reject missing named sections during blank-memory bootstrap.
• Validate curator semantics inside the active transcript with aggregated decision and field-path diagnostics.
• Bind proposal schema variants to valid target, action, delta, and finding combinations.
• Classify exhausted curator responses as curation-invalid-response.
• Run hosted server integration tests against current workspace sources.

Issue 1: PR 133 was based on main before PR 132 merged. Its history needed to be synchronized with the current base.
Resolved by commit sha 1: Commits a119633, 6451265, and 5648c3d were rebased onto main at 59dc0c6. Current main is now an ancestor of the PR head.

Issue 2: PR 132 added a Breaking Changes subsection and a unified skill catalog entry to the coding-agent CHANGELOG. Those entries needed to be excluded from PR 133.
Resolved by commit sha 2: Commit b81c07f removes exactly those five added lines. The resulting Unreleased section matches the pre-PR 132 file.
