Cleans up duplicate edge points left by the boost_edges() bug (fixed
in previous commit). Each unique (src, dst, edge_type) keeps the
highest-weight point; duplicates are deleted. Default --dry-run.
Duplicate edges root cause — critical logic bug in QdrantStore:
boost_edges() and add_contradicts_edge() always created new points with
random UUIDs instead of reusing existing point IDs. Each boost call
added a duplicate point rather than updating in-place, causing 190
duplicate edge rows for 73 unique edges.
Sigma fix — compute_sigma() checked total node count (311 >= 200 floor)
but the largest connected component had only 2 nodes. Now checks the
largest CC size, which is the correct semantic for Humphries-Gurney
sigma validity.
The Qdrant _TableShim returned updated_at as ISO strings (not datetime
objects), causing str.replace(tzinfo=...) to fail with
"str.replace() takes no keyword arguments". Parse strings via
datetime.fromisoformat() before timezone handling.
Also add missing delete(where) and update(where=, values=) methods to
_TableShim so the LanceDB-compatible shim works with Qdrant's payload
collection, plus a _parse_where() helper to convert where clauses to
Qdrant Filters.
- Fix build_runtime_graph to use backend-agnostic records_as_dataframe()
and edges_as_dataframe() instead of LanceDB-specific open_table()
- Fix CLI topology command: JSON-RPC envelope + result extraction
- Fix community.py KeyError when graph has nodes but no edges
- Update doctor check (i) to report Qdrant collection counts when
Qdrant is active, LanceDB versions when LanceDB is active
- Fix HIBERNATION startup exit: dispatch REQUEST_ARRIVED on boot
- Fix systemd unit: StartLimit* keys in [Unit] section
- Broaden capture.py exception handler for deferred capture failures
- Add records_as_dataframe() and edges_as_dataframe() to MemoryStore
- doctor: skip LanceDB check when qdrant_storage/ dir detected
- topology: use daemon socket instead of local store (avoids lancedb crash)
- qdrant_store: add records_as_dataframe() + wire into _TableShim
so build_runtime_graph() works with Qdrant (was returning empty)
