#!srfv1
# Exact, independently-sourced unit values for the Oregon College Savings Plan
# (Embark) portfolios. These are the ONLY observed values in this project;
# everything in data/ORCBI.srf and data/ORC42.srf between them is derived.
#
# Keep this file. The wayback-sourced rows are not otherwise recoverable if the
# Internet Archive prunes those captures, and there is no public historical NAV
# endpoint for this plan.
#
# source::launch
#   Every portfolio in the plan launched at exactly $10.00. Verified by
#   back-solving the live feed's `inception` field, which is the ANNUALIZED
#   since-inception return: nav / (1 + inception)^years lands between 10.0005
#   and 10.0038 for all 37 priced portfolios in the feed. The Plan Disclosure
#   Booklet corroborates the date: "The Portfolios commenced operations in
#   September 2018."

#   Captures of https://marcom.vestwell.com/data/fund-performance/OR-CSP.json
#   The `evidence` field is the Internet Archive timestamp; fetch with
#   https://web.archive.org/web/<evidence>id_/<url>
#   `date` is the feed's own navDate, not the capture date. The feed publishes
#   the prior business day's value, so navDate lags the capture by ~1 day.
