v0.1.0 — a ladder you can open and read

A wallet opens the link, deposits demo USDC against a risk profile, and sees
the ladder it now holds. Nothing in the demo needs access to our systems: the
catalogue, the ratings, the vault and the position are all read from Solana
devnet, and the deposit is signed by the visitor.

What the release covers (US1):

• the composer reads the deployed catalogue by scanning the programs, joins
  every instrument with the rating the program would read beside it, and
  shows the whole term sheet before the signature — including how many whole
  units each rung buys and the indivisible tail that stays in the wallet
• the deposit is one transaction, and the program checks every constraint of
  the proposal again rather than trusting the client
• the statement reads the position back: composition, remaining term,
  weighted rating, and the accrued management fee on a line of its own, with
  every other figure net of it
• the app is served from GitHub Pages out of this repository

Measured on devnet, worst of five samples, over the public endpoint the
deployed site uses:

SC-001 term sheet visible 850 ms of 3000
SC-002 deposit confirmed 580 ms of 5000
SC-008 dashboard on screen 936 ms of 2000

SC-004 threshold breaches over 200 generated catalogues 0
SC-005 units lost to rounding over 1000 deposits 0

What this release does not do, and it matters:

• there is no way out of a position. Money goes in and does not come out:
  SC-003 and SC-006 are not merely unmeasured, they are unreachable by
  construction, and there is no backstop pool yet.
• the ladder does not roll. Nothing reinvests a matured rung, so after the
  first maturity it stops being a ladder.
• nothing reacts to a downgrade. The position carries the flag; no
  instruction sets it.
• the ratings and the issuers are ours. There is no Moody's or AlphaLedger
  feed, the instruments are minted by our own demo issuer, and the route is
  deterministic — so slippage and market depth do not exist as phenomena
  here, rather than being small.
• no audit, and no regulatory compliance of any kind.

Not real securities, ratings, or offers.
