[clockwork-labs-bot]

Summary

• Update automatic migration docs to reflect empty-table removal behavior.
• Document accessor/source-name metadata changes and index accessor rename limits.
• Add a public MCP reference covering spacetime mcp, host-wide vs database-scoped tool shapes, permissions, and common errors.

Audit notes

• Baseline: existing open bot/docs-audit PR docs: update automatic migration compatibility notes #5723; merged current origin/master into bot/docs-audit before today's audit pass.
• 2026-08-15 commit-impact pass checked new master commits b1291ee11 / Fix C# HTTP timeout clamp #5751 (C# HTTP timeout clamp), 0948a1b3b / Bump version to 2.8.2 #5752 (2.8.2 version bump), and 524b4487d / LLM benchmark: new evals + improved tooling #5583 (LLM benchmark evals and server skill updates).
• Checked the changed server skill guidance from LLM benchmark: new evals + improved tooling #5583 against public docs for procedures, HTTP, scheduled procedures, views/query-builder views, view primary keys, client visibility filters, schedule tables, defaults, lifecycle connection IDs, and deterministic context guidance.
• Checked Fix C# HTTP timeout clamp #5751 against public procedure HTTP docs; the 30-second default and 180-second maximum timeout are already documented.
• No new high-confidence public docs mismatch was found on 2026-08-15, so this run added no new docs correction beyond merging current master.
• Unrelated untracked local files were present at repo root (.openclaw/, AGENTS.md, HEARTBEAT.md, IDENTITY.md, SOUL.md, TOOLS.md, USER.md) and were left untouched.

Validation
