Splits the 459-line credentials.py into two submixins plus a composing
CredentialsMixin in credentials/__init__.py:
_core.py (~190) Credential capture: upsert, list, filters,
per-attacker / per-secret reads, attacker_uuid
backfill
reuse.py (~270) CredentialReuse correlation: upsert, candidate
mining, list/get + the _enrich_with_secret helper
that lifts the printable/b64 from underlying rows
_merge_unique stays with reuse.py (its only caller).
_enrich_with_secret stays with reuse.py — it's an internal helper of
list_credential_reuses / get_credential_reuse_by_id, never called
from the capture path.
Moves the 31 MazeNET topology methods (topologies CRUD, LANs, deckies,
edges, status events, mutation queue) into sqlmodel_repo/topology.py.
Includes _assert_pending and _check_and_bump_version concurrency
guards.
This is the last domain extraction; sqlmodel_repo/__init__.py is now
~165 lines: lifecycle (initialize/reinitialize/migrations), the admin
self-heal seed, get_state/set_state, and the mixin composition.
Splits the AttackerIdentity and Campaign clustering reads/writes into
sqlmodel_repo/identities.py and sqlmodel_repo/campaigns.py.
Both call _deserialize_attacker (identities only) which resolves
through AttackersMixin via MRO.
Moves the 19 attacker-domain methods (core CRUD, behavior, sessions,
smtp targets, log-derived activity views) plus the _deserialize_attacker
and _deserialize_behavior helpers into sqlmodel_repo/attackers.py.
Moves the 8 log methods (incl. get_stats_summary aggregator) into
sqlmodel_repo/logs.py. get_log_histogram remains an abstract dialect
override point; sqlite/mysql subclasses still override it via MRO.
Moves the 6 fleet-decky methods (incl. cross-source list_running_deckies
aggregator) into sqlmodel_repo/fleet.py. _serialize_json_fields and
_deserialize_json_fields move to _helpers.py since they're shared
across fleet, topology, and canary.
Moves the 7 user CRUD methods into sqlmodel_repo/auth.py.
_ensure_admin_user stays in __init__.py so DECNET_ADMIN_PASSWORD
remains addressable at the module path tests already monkeypatch.
Moves upsert_attacker_intel, get_attacker_intel_by_uuid,
and get_unenriched_attackers into sqlmodel_repo/attacker_intel.py.
Composed onto SQLModelRepository via mixin inheritance.
Pure rename — the old monolithic 3505-line file becomes
decnet/web/db/sqlmodel_repo/__init__.py. No code changes.
Subsequent commits will extract per-domain mixins out of __init__.py
to mirror the topical layout used by decnet/web/db/models/.
