research: park Phase B fip breadth; race guard and compact evidence

Log the 21:14 orphan as a snapshot-build race, rewrite the context table to
authoritative ICs only, and soften the vol-tilt warning. Add extender completion
manifest + breadth refuse guard; strip intermediate/orphaned reports; park the
thread (no book sim, no deploy).

+### Phase B fip breadth IC (2026-07-18/19) — compact evidence
+
+Canonical artifacts:
+
+- `fip-reconcile-20260719-000520.json` — single-sourced authoritative ICs
+  (unconditional liquid fip, tiers, prod-subset, mom-conditional, context
+  signals). Membership symbol dumps stripped after the decision; narrative in
+  [`docs/research/fip-breadth-ic.md`](../docs/research/fip-breadth-ic.md).
+- `fip-breadth-20260718-211440-fingerprint.json` — prod-snapshot fingerprint
+  pass (fip IC −0.045 / t −2.91).
+
+Removed as superseded / dangerous intermediate noise (recoverable from Git):
+
+- `fip-breadth-20260718-211440-breadth.json` (+ wrapper) — **orphaned** +0.0575
+  / t +5.12 from racing a partial `research.sqlite`. Kept out of the tree so it
+  cannot be re-mythologized.
+- `fip-breadth-20260718-194828*.json` — fingerprint-only partial run.
+- `fip-breadth-diagnostics-20260718-213705.json` and `…-213908.json` — dual-path
+  diagnostics superseded by the single-sourced reconcile.
