docs(architecture): resolve all open questions (OQ-01..13), mark specs reviewed
- OQ-08: shell convention = assembly-supplied serve config (shell argv
for shell_request; exec wrapper argv + command string for exec; no
crate default; unset -> clean decline)
- OQ-11: direct-streamlocal = universal compile + runtime Unix-gated
decline (channel and listen flow)
- OQ-10: closed as contract + upstream constraint; derivation rules
formalized in mapping.md (Exit chunk -> SSH exit reporting), incl.
the -1/genuine-SIGHUP fidelity tradeoff and an unmapped-negative
fallback rule
- OQ-01/04/09/13: resolved as fully-decided dispositions (ADR-001/
ADR-004/fixed decline postures); remainders were forecasts about
consumers, not pending alkssh decisions; upstream deps now listed
as watch items, not OQs
- OQ-12 restored to the tracker (dropped in the rewrite)
- review-agent criticals/warnings fixed: exec-unset + wrap mechanics
specified, streamlocal listen gate added, stale deferred/tracked
language removed, ADR-006 title fixed, 0.64.1-vs-0.65.0 crosswalk
added in ADR-004, ADR frontmatter aligned to 'reviewed'
All specs + ADRs 001-006 now reviewed; implementation may begin.
