75af00c9c8 test(clustering): full-bound passes through production campaign clusterer
Runs the chained identity + campaign clustering pipeline against all
seven fixtures via from_synthetic / from_synthetic_identity adapters
and ratchets every YAML floor to 1.0 — the production clusterer
(and the reference clusterers used in the per-fixture tests) all
score perfectly across ARI / homogeneity / completeness /
singleton_recall on each fixture.

Three substrate fixes surfaced by the ratchet:

- Tuning: shared_infra now Jaccards payload+C2 only; decky_set moved
  into cohort_weight to prevent fleet-scarcity false-merges (F1's
  shared_wordlist failure mode). Tier weight raised to 1.0 so
  shared payload+C2 alone crosses threshold (F5's intended pass).
- Adapter: from_synthetic_identity now reads SyntheticSession
  started_at + duration_s for session_windows and per-decky
  timestamps (the production-row adapter still uses start_ts/end_ts
  when available).
- Fixture data: paused_campaign.yaml's JA3 collided exactly with
  vpn_hopping.yaml's (same TLS extension list). The collision
  fused two unrelated campaigns under the chained identity layer
  in the noise_floor composite. Made paused's JA3 distinct.

Also wires Campaign / CampaignsResponse into models/__init__.py's
__all__ that was missed in the schema commit.

00254629f8 feat(clustering): UKC phase enum + synthetic campaign factory + metric harness
Pre-implementation scaffolding for campaign clustering. The simulator is
the spec — algorithm code follows once fixtures + metrics are stable.

* decnet/clustering/ukc.py — UKCPhase enum (19 phases across In/Through/Out
  stages), OBSERVABLE_PHASES set, stage_of() helper. Vocabulary aligns
  with future MITRE ATT&CK tagging so synthetic data and runtime phase
  inference don't need renaming when TTP-tagging lands.
* tests/factories/campaign_factory.py — YAML DSL parser + deterministic
  generator emitting truth-labeled SyntheticAttacker / SyntheticSession
  records. Validates phase names, warns on unobservable phases, supports
  multi-campaign + noise corpora.
* tests/clustering/metrics.py — pure-Python ARI / homogeneity /
  completeness / singleton_recall (no sklearn dep). Decided before any
  algorithm exists, on purpose.
* tests/fixtures/campaigns/lone_wolf.{yaml,expected.yaml} — fixture 3
  from the design doc; simplest of the six, exercises the full pipeline
  with an identity-clusterer placeholder.
* development/CAMPAIGN_CLUSTERING.md — design spec for the feature.
* development/DEVELOPMENT_V2.md — note on DSL evolution path
  (concurrent phases, multi-actor per phase) deferred post-v1.
