Record Fund Positions

Gives a fund's declared positions snapshot, as of a stated valuation date, its own citable execution_hash -- the upstream input-receipt that the proven NAV chain (art-373-recompute-fund-nav) currently hashes internally, and that a separate wiring node can instead cite via an optional positions_ref rather than re-declaring the same holdings. Attests that a declared snapshot exists exactly as stated, over caller-supplied holdings rows (security_id, quantity, currency) and a declared shares_outstanding. HARD FENCE: fund_id, valuation_date, every holding row, and shares_outstanding are supplied and asserted, never fetched (zero-egress); this attests THAT a declared snapshot exists as stated, never whether it matches a custodian record, never a live position feed. Section 25 private-inputs review ruled not applicable and stated explicitly: holdings are echoed in cleartext by design, since the node's function is to give the declared snapshot a citable hash, not to hide it behind a commitment. Not fund NAV recomputation (art-373) and not a pricing input (a sibling record_pricing_inputs node covers pricing). Corrections cite the prior artifact via the SPEC.md top-level supersedes field, not a bespoke status registry.
