What changed

• Resolve the second-round expert review findings in the platform specification.
• Move approval storage and workflows before the releases that depend on them.
• Define the v0.5 reference adapters and isolation probe, while keeping broader adapter coverage in v0.9.
• Align job, endpoint, decision, approval, and event contracts.
• Complete compatibility alias mappings and define measurable idle-supervision evidence.

Why

Several release gates depended on capabilities scheduled for later releases. Some versioned contracts also used inconsistent names or referenced schema fields and protocol messages that did not exist.

Impact

The implementation roadmap now has explicit dependency order, complete schema support, consistent state names, and testable acceptance gates. Archived job names can be reused, replacement decisions keep their history, and compatibility behavior has a defined target.

Validation

• bash tests/run: 100 tests passed
• Targeted review-contract check: 20 required clauses present and 7 stale clauses absent
• git diff --check: clean
