The composition suite's idleSilenceMs: 30000 was below the suite's own send
bound (dsh-terminal-bash timeoutMs: 300000), so the comment claiming silence
could settle nothing was wrong: a regressed send still settled as inferred_idle
after ~30 s and only the accumulated case timeout caught it.
The case now records every send's waitReason and requires at least six
stdin_read settlements with no inferred_idle. Reinstating the removed prompt
override fails it in 30 s with 'expected 0 to be greater than or equal to 6'
while the output assertions still pass. The silence tier returns to its product
default.
Also renames the two stale test titles ('private shell prompt', and the
cancellation phase that no longer covers an initialization send), pins the
stdin_read fallback's session retention, and records the interactive-child
consequence of that retention in the package README pair and the Agent Note.
