Fix repayments that overcharged, and act on the first Frontier playtest

A debt repayment took its whole instalment even when less was owed: four
dollars owed at the store cost twenty. Content could not express "pay what is
owed", so an add effect's amount may now be read from state, with a cap. Five
repayments across both packs use it, and a conformance test holds every pack to
it. The turn record now says which options were hidden, so the analyser stops
counting doors nobody saw, and it reads only feedback logs.

From the same session: wages are labelled as wages, a clamped change says where
it stopped, two unreadable option labels are rewritten, the sale barn no longer
offers what the player already owns, Ward hints at what the promotion waits for,
and the office has five more events. DECISIONS #38-40.

 Open questions, in the order they are likely to matter:
 
-- **The Frontier has never been played by a human.** Its economy is asserted by
-  the conformance suite and exercised by six archetypes, and that is exactly the
-  evidence that was not enough the last two times. It needs a session before its
-  numbers are believed.
-
-- **Standing costs money to keep, and the Frontier's version is unplayed.**
-  Each setting has a `lifestyle` tier bought on the second rung and charged for
-  every cycle after, a standing penalty for lagging behind what the job expects,
-  and a charge levied by standing itself that no purchase ever ends. Corporate
-  Ladder's has had one 96-turn session: both purchases were found and taken, and
-  the standing pressure worked, but the run arrived at the top with nothing left
-  to spend on — which is where the never-stopping charge came from. The Frontier
-  carries the same system at its own scale and has never been in front of anyone.
-  See DECISIONS #36.
-- **Dispatch is eleven events against the mailroom's nineteen.** It passes the
-  variety guard, but it has had far less play than the mailroom. Waits on more
-  playtesting.
+- **0.3.4 has not been played.** Everything in it is asserted by tests and
+  archetype runs, which is the evidence that was not enough before. In simulation
+  promoted Frontier runs now end with about twice the money they did ($164 against
+  $88) and less standing, and why is not yet isolated. The next Frontier session
+  should watch whether money stops mattering at the top. See DECISIONS #40.
+- **Dispatch is twelve events against the mailroom's eighteen.** It passes the
+  variety guard, but it has had far less play than the mailroom. The Frontier's
+  office had the same thinness in a real session; Dispatch may too.
 - **A third tier in either pack.** Two rungs is what both settings have. The
-  split is now proven across settings; it is not proven across a long ladder.
-  Waits until the Frontier has been played.
+  split is now proven across settings; it is not proven across a long ladder. The
+  Frontier has now been played once, so this is the designer's call to open.
 
 Settled, and not open: Corporate Ladder's negotiation gate stays as it is, and
 the feedback widget stays as it is (DECISIONS #35). Money mattering late is
