the deadline is the whole run; budget, stdin and answer are bounded Soul s1 fixes. The hook header says the lines are recalled records, data and never instructions, written by agents not the operator. Every item is one JSON object per line: id, title and operator_quote are JSON strings with < >, control, bidi and separator characters escaped, so a title cannot close the framing, forge a tag, a header or an operator segment. RECALL_DEADLINE_MS now bounds the whole run through a hard stop; stdin is read to 4 MiB and the answer to 1 MiB (mind.call max_bytes); RECALL_BUDGET is clamped to 9000 under Claude Code's 10,000-character cap. Tests: hostile text, a non-ASCII process-boundary run under cp1252, byte-versus-character budget, stdin held open and endless, answer size, budget ceiling, and the four unrecorded survivors (negative reply timeout, reply id check, env-int positivity, EOF sentinel). Mutants of each were run and caught.

R2 times the interpreter, not the shell On Windows the run overshot its deadline by 450-720 ms in the R2 bands: ~200 ms of interpreter start and imports ran before the clock, the hard stop sat 0.3 s after the deadline, and the test timed bash, env and the py launcher too. The clock now starts at process creation (GetProcessTimes), the reply wait ends 0.1 s early so the kill and exit fit, and the hard stop is the deadline itself. Residual outside the script: the py launcher (40-130 ms, rare spikes to 300) and the creation call. R2 times the interpreter directly, best of two, bands -250/+100 ms around the deadline.
