Review comments at @plugin/skills/agentmemory-rest-api/REFERENCE.md:
- Line 65: Update the method listed for `/agentmemory/graph/index/migrate` in
the generated reference from GET to POST, matching the route registration in
`src/triggers/api.ts`.
Review comments at @READMEs/README.pl-PL.md:
- Line 1449: In the README statistics sentence, change the noun after “66” from
“zakresy” to the genitive plural “zakresów”; leave the other statistics
unchanged.
Review comments at @scripts/release-gate/graph-index.mjs:
- Line 10: Declare ws as a direct root development dependency in the package
manifest, using the project’s intended version, so
scripts/release-gate/graph-index.mjs does not rely on transitive hoisting.
Review comments at @src/functions/temporal-graph.ts:
- Around line 244-261: Replace the full adjacency scan in temporal edge
reconciliation with a key-specific lookup using the existing KV.graphEdgeKey
index, or an index posting keyed by source, target, and type. Preserve selection
of the appropriate predecessor edge without increasing the graph reader’s read
budget; locate this logic in the temporal reconciliation block using
createGraphIndexReader and existingEdge.
Review comments at @src/state/graph-index-migration.ts:
- Around line 131-133: Update errorMessage to return the original message for
GraphIndexError as well as GraphIndexMigrationError, so corrupt index controls
report the explicit migration action instead of suggesting resume after a
storage failure.

Base rewrote graph-retrieval.ts and its tests for the bounded index reader (rohitg00#1559), so both conflicted files take the base version here; the best-score fix is re-applied on top of the new retrieval path in the next commit. Signed-off-by: Dmitrii Zhukov <dmitry0983@gmail.com>

Thanks for this — request-time enumeration of the complete graph scopes was what made large stores unusable. One data point on the migration path from a large legacy store, since the packaged gate exercises 100 nodes / 300 edges and initial discovery still reads complete scopes.

What I would want settled before running I am willing to run the migration against a copy of this store (~2 GB, outside the primary store) and report wall time, peak memory, and whether the engine heartbeat survives, if that is useful. |

Large graph searches currently enumerate complete node and edge scopes before traversal limits apply. This change replaces those request-time scans with generation-scoped retrieval indexes maintained alongside canonical writes. Keyword and vector results keep the optional 500 ms graph budget.
Name, character, provenance, adjacency, exact relationship and inventory postings use bounded records and point reads. Search, graph views, graph-node detail, temporal queries, optional reflection graph context, viewer counts and server graph statistics use the indexes. Readers verify generation and revision before returning evidence; import, mesh, snapshot restore, deletion and reset cannot publish a mixed or stale view. Oversized projections retain canonical data and report partial coverage.
Temporal reconciliation selects the highest-version current predecessor using an exact source/target/type posting, with deterministic ID tie-breaking and canonical validation inside the existing 512-read budget. Unrelated or historical edges cannot consume that lookup budget. Older index controls fail closed and require an explicit rebuild instead of silently losing predecessor tracking.
Uninitialized stores, including fresh installations, require explicit initialization:
Initial discovery still reads complete scopes because the pinned engine cannot paginate them. It requires a maintenance window. A durable, bounded ID manifest then supports idempotent replay, saved progress and restart recovery. Startup resumes sealed work without another legacy scan; interrupted discovery requires renewed consent. Missing/corrupt metadata fails closed with an explicit recovery message. Automatic legacy boot compaction is deferred, and unavailable counts appear as unknown.
