Subject: [PATCH] feat(waves): refuse to launch an agent at an ALREADY-BANKED
 target (R43/R45)

wave_args asserts a target is open AT DRAW TIME, then the payload sits on disk while
gates run. S71 launched ov_SC01_006/func_8017F9F8 from a payload built before the gate
that banked it; the agent spent a full run to report "STALE CARD - already banked
today", with no .s left to score against. Filtering the wave-2 payload found 3 such
targets of 27.

launch_check.py re-asks the same oracle everything else uses (a bank REMOVES the
INCLUDE_ASM stub, so corpus.stubs not containing the symbol IS the bank), either for one
target or by filtering a {wave,targets} payload in place. An unreadable binary is treated
as OPEN - a tool fault is not a verdict about the subject (R40).

+"""Refuse to launch a drafting agent at a target that is ALREADY BANKED (P31 S71, R43/R45).
+
+`wave_args.py` asserts a target is open AT DRAW TIME. A wave's payload then sits on disk while gates
+run, so by launch time some of its targets are banked — and an agent handed one burns a full run to
+report "STALE CARD — already banked today", with no `.s` left to even score against. Measured S71:
+`ov_SC01_006/func_8017F9F8` was banked by gate `commit:3604` and drafted afterwards from a payload
+built before it.
+
+The open oracle is the same one everything else uses: a bank REMOVES the INCLUDE_ASM stub, so
+`corpus.stubs(binary)` not containing the symbol IS the bank.
