Replaces LICENSE (GPLv3 -> AGPLv3) and prepends
`SPDX-License-Identifier: AGPL-3.0-or-later` to every source file
across decnet/, decnet_web/, tests/, scripts/, and tools/.
Rationale: closes the GPLv3 ASP loophole so any party operating a
modified DECNET as a network service must offer their modified
source. Personal copyright (Samuel Paschuan) + inbound=outbound
contributions make a future unilateral relicense infeasible.

No behavior change; comments only.
Lays the storage and bus substrate for the "credential reuse patterns"
task in DEVELOPMENT.md and scaffolds decnet/vectorstore/ as the future
substrate for statistical attacker re-identification over behavioral
fingerprints. No correlator, profiler, API, or dashboard wiring in
this commit — see TODO.md for the handoff.
Schema:
- Credential.attacker_uuid (nullable FK to attackers.uuid),
backfilled by the profiler post-write to avoid coupling the
capture path to the profiler's ordering.
- CredentialReuse table — UUID PK, JSON list columns for the
accumulating attacker_uuids/ips/deckies/services, target_count
(the discriminative scalar), confidence reserved for a future
fuzzy-credential pass.
Repo:
- upsert_credential_reuse / list_credential_reuses /
get_credential_reuse_by_id / update_credential_attacker_uuid.
- Renamed pre-existing get_credential_reuse(secret_sha256) to
get_credential_attempts_for_secret(secret_sha256) — the new
findings table needs the cleaner name.
Bus topics:
- credential.captured (one per Credential upsert)
- credential.reuse.detected (correlator-emitted on insert/grow)
Vectorstore subpackage (decnet/vectorstore/, flat layout mirroring
decnet/bus/):
- BaseVectorStore ABC keyed by (kind, id) — kind discriminator
means new feature families are additive, no schema migration.
- FakeVectorStore (in-memory L2 KNN), NullVectorStore (no-op for
DECNET_VECTORSTORE_ENABLED=false), SqliteVecVectorStore (lazy
sqlite_vec extension load, one vec0 virtual table per kind).
- get_vectorstore() env-driven dispatch with graceful fallback
to FakeVectorStore when the sqlite-vec extension isn't on the
host, so workers don't crash on a missing optional dep.
Tests: 26 new (11 cred-reuse repo, 15 vectorstore). Existing
credentials and base-repo tests updated for the rename. Total: 34
passing on the touched files.
