Wiring: expose reconciliation API + pipeline-core ensemble repoint

[Polichinel]

Epic: #31 · story implementation

⚠️ Corrected 2026-06-26 (verified on origin/development). The original body — "pipeline-core ensemble managers call views-postprocessing reconciliation" — was never true and is now doubly wrong:

• pipeline-core's development still imports views_reporting.reconciliation (ensemble.py:747, dataframe_ensemble.py:921, modules/reconciliation/__init__.py:4) — it was never repointed to vpp.
• The DIP port/adapter PR (pipeline-core #217, implementing #195) is OPEN/unmerged (the port domain/reconciliation.py exists on dev; the adapter does not).
• The reconciler's final home is views-frames (views_frames_reconcile, Epic 11 / Epic 11 — Reconciliation is a frames sibling: add views_frames_reconcile (ADR-023) views-frames#131), not vpp — vpp's copy is being deleted (C2 — Retire views_postprocessing/reconciliation/ (moved to views_frames_reconcile) #62).

What this becomes

The pipeline-core "repoint" is no longer a vpp task and no longer targets vpp. It becomes the pipeline-core clean cutover (gated on views-frames v1.7.0): delete the views_reporting.reconciliation imports, direct-import views_frames_reconcile (a stable foundation pipeline-core already depends on — no port/injection needed: decision C / collapse), geography injected as data sourced from the producer (datafactory/viewser, per D-07), never fetched by the reconciler (ADR-023 charter). Tracked in pipeline-core.

Superseded by Epic 11 (views-frames#131). Nothing actionable remains in vpp here — the cutover lives in pipeline-core, vpp's deletion is #62. See register C-42 (the stranded-migration risk). Recommend close.

Update 2026-06-24 — the repoint is now two parts.

1. Point path (this issue's original scope): repoint ensemble.py / dataframe_ensemble.py — the only live reconciliation consumers (used by skinny_love / white_mustang). Cleanup that frees views-reporting of torch.
2. NEW — probabilistic path: PredictionFrameEnsembleManager has no reconciliation hooks (reconciliation=None, prediction_frame_ensemble.py:280-281). The upcoming UN deliverable needs probabilistic reconciliation there. Tracked in a new pipeline-core issue under their #193.

The reconciler API here (ReconciliationModule, reconcile_proportional) is already probabilistic-ready; consumers must chunk by time (C-38) and resolve sample alignment (C-37).

Update (Epic 11): the pipeline-core repoint is already done via injection — pipeline-core #195 (PR #217) built the Reconciler port + a frames-only adapter; pipeline-core has zero imports of vpp reconciliation. With the reconciler moving to views-frames (#131, below pipeline-core in the graph), the consumer repoint is simply import from views_frames_reconcile at the composition root (views-platform/views-models#191). Superseded by Epic 11 — nothing to do in vpp here.

Closing — superseded (as the corrected body says). The pipeline-core repoint was never a vpp task and never targeted vpp; the reconciler's home became views-frames (views_frames_reconcile, Epic 11 / views-frames#131, v1.7.0). vpp's copy is now deleted (#62 / PR #63, merged to development 2026-06-26). pipeline-core ran its own cutover in-repo (PR #217 merged). Nothing actionable here. See register C-42.
