- OQ-10 is not resolved: the mapping-contract derivation details (name
table, core-dumped disposition, −1 disposition) are working
dispositions on mapping.md's exit rows until formalized there / as an
ADR-006 amendment. The 1a40bfb commit prematurely closed them and left
ADR-006's reference (OQ-10 open) stale.
- Premise correction integrated into the seed, not argued after the
fact; the portable-pty 0.9.0 source now cited as verified
(From<std::process::ExitStatus> maps signal-terminated → code 1 +
locale-dependent strsignal string; the number is unrecoverable).
- mapping.md: exit_signal row and the Open Questions entry updated to
open OQ-10 with the working-draft framing.
Verification: cargo test (2/2 targets ok), cargo clippy --all-targets -- -D warnings, cargo fmt --check (docs-only change)
