- OQ-10 resolved: alkssh derives SSH exit-signal from the alktty exit
chunk's negative code (−N = signal N, pipe path) server-side; −1
(alktty's could-not-determine sentinel) → exit-status(255), never a
signal claim; core_dumped never asserted in v1; no alktty wire change
- new verified backend finding recorded: portable-pty 0.9 reduces
PTY-mode signal termination to a plain exit code 1 (signal number
unrecoverable through its trait surface) — faithful exit-signal on
the PTY row is an alktty/portable-pty upstream ask, not an alkssh one
- research docs (poc-3 §D.2, pocs.md, mapping-table rows) restated
accurately instead of carrying inline correction scaffolding
Verification: cargo doc --no-deps earlier this session (docs-only change)
