Splits the 990-line AGENTS.md into a 184-line map (architecture, where-to-find index, always-on invariants, capability matrix, maintenance contract) plus 18 new docs/*.md files holding the deep content per topic (storage, schema and query languages, indexes, embeddings, branches/commits, runs, merge, changes, execution, policy, server, CLI reference, audit, errors, CI, constants, v0.3.1 notes). Adds scripts/check-agents-md.sh and a check_agents_md CI job that verifies every docs/ link in AGENTS.md resolves and every doc in the canonical set is linked. CLAUDE.md remains a symlink to AGENTS.md. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

# Change Detection / Diff
|
|
|
|
`changes/mod.rs`. Three-level algorithm:
|
|
|
|
1. **Manifest diff**: skip sub-tables whose `(table_version, table_branch)` is unchanged.
|
|
2. **Lineage check**:
|
|
- Same branch lineage → fast path: use the per-row `_row_last_updated_at_version` column to classify Insert/Update/Delete.
|
|
- Different lineages → ID-based streaming comparison.
|
|
3. **Row-level diff**: streaming, no full materialization.
|
|
|
|
## Public API
|
|
|
|
- `diff_between(from: ReadTarget, to: ReadTarget, filter: Option<ChangeFilter>) -> ChangeSet`
|
|
- `diff_commits(from_commit_id, to_commit_id, filter)` — cross-branch safe.
|
|
|
|
## Types
|
|
|
|
```
|
|
ChangeOp: Insert | Update | Delete
|
|
EntityKind: Node | Edge
|
|
EntityChange { table_key, kind, type_name, id, op, manifest_version, endpoints?: {src, dst} }
|
|
ChangeFilter { kinds?, type_names?, ops? }
|
|
ChangeSet { from_version, to_version, branch?, changes[], stats }
|
|
```
