C2 — Retire views_postprocessing/reconciliation/ (moved to views_frames_reconcile)

[Polichinel]

Cross-repo cutover for views-frames Epic 11 (views-platform/views-frames#131). blocked on C1 (views-models repoint). Closes #31.

Problem

The reconciler has moved to the views_frames_reconcile sibling in the views-frames distribution and consumers are repointed (C1). views-postprocessing was only ever a way-station — FAO delivery doesn't use reconciliation. Delete our copy so the repo screams its real job (partner delivery).

Work

• Delete views_postprocessing/reconciliation/ (proportional.py, grouping.py, frames.py, validation.py, module.py, init.py).
• Delete its tests tests/test_reconciliation_*.py, fixtures tests/fixtures/reconciliation_*.npz, and scripts/gen_reconciliation_*.py.
• vpp deps unchanged (already depends on views-frames; no new dep — vpp does not consume the reconciler).
• Update docs/CICs/ReconciliationModule.md + the migration notes to point at views-frames; move register C-37/C-38 tracking to views-frames.

Acceptance criteria

• No reconciliation code/tests/fixtures remain in views-postprocessing.
• PYTHONPATH=. pytest -q green; ruff clean.
• Epic: Migrate forecast reconciliation into views-postprocessing (frames-native, parity-proven) #31 (the migrate-into-vpp epic) closed, pointing at views-frames#131.

Dependencies

• Blocked on C1 (consumer must import from views-frames first).
• Only proceed once views-frames#137 (v1.7.0) is released, C1 merged, and CI green — release → repoint → delete order.

Files

delete views_postprocessing/reconciliation/, tests/test_reconciliation_*.py, tests/fixtures/reconciliation_*.npz, scripts/gen_reconciliation_*.py; update docs/CICs/ReconciliationModule.md.

Done in PR #63 (merged to development 2026-06-26, merge commit c9e3840). Deleted views_postprocessing/reconciliation/ (6 modules) + 6 tests + 2 parity fixtures + 2 gen scripts + the ReconciliationModule CIC; migration doc → pointer to views-frames; dropped the stale CIC-index entry (review fix). ruff + pytest green (74 passed / 43 xfailed); CI (check-branch, Analyze, CodeQL) green.

Deletion-safety verified on origin/development pre-merge: no unguarded importer of views_postprocessing.reconciliation anywhere — C1 (views-models#191) had already repointed reconciler_factory to views_frames_reconcile (PR #202); only guarded pytest.importorskip tests remain (skip when absent). (Closes didn't auto-fire: PR targeted development, not the default branch.)

✅ Unblocked — the reconciliation cutover landed (Decision K)

The reconciler's live home is now `views_frames_reconcile` (views-frames v1.7.0 sibling). views-pipeline-core PR #217 merged to `development` (`6427b9d`, 2026-06-26): pipeline-core reconciles via its `Reconciler` port, and views-models (`reconciler_factory`) constructs + injects `views_frames_reconcile.ReconciliationModule`. Nothing imports vpp's `reconciliation/` copy — it's a stranded way-station (vpp was only ever a parity oracle; FAO delivery doesn't reconcile).

Note: this is Decision K, not the earlier C plan — but it doesn't change C2's premise. vpp's reconciliation copy is dead either way, so this issue proceeds as written: delete `views_postprocessing/reconciliation/` + its tests/fixtures/scripts, and repoint `docs/CICs/ReconciliationModule.md` at `views_frames_reconcile`. (The earlier "blocked on C1 / views-models repoint" gate is satisfied — views-models already imports `views_frames_reconcile`.)
