The 'queues an Enter-submitted draft while compaction is active' test
pastes a large message to push the session over the fixture's 22k
threshold_tokens. At repeat(500) the payload is only ~4k tokens — the
other ~18k came from the ambient system prompt (tool schemas + skills
index + memory), leaving the trigger margin-less. The hermes-agent
skill hub restructure (e3d524b482) shrank the bundled skills index by
~160 tokens and dropped the total just under threshold: compaction never
started, waitForHeldCompletion() hung, and the test timed out at 90s on
every branch since — including main (first red run: 9a4d1a0130).
Bump the payload to repeat(1500) (~12.4k tokens, total ~30k) so the
test crosses the threshold on its own weight with ~8k tokens of margin,
and document the invariant so the next prompt-weight change doesn't
resurrect this.
