The monolithic open-questions.md (1310 lines, 47 OQs) was large enough to be unmanageable, with high size variance (OQ-42 at 220 lines next to OQ-06 at 8). Decomposed into one file per OQ under docs/architecture/questions/ (NNN-slug.md, mirroring the ADR convention), with open-questions.md retained as the index: theme-grouped tables plus a cross-theme Deferred/Blocked section that surfaces the 6 deferred OQs with their Blocked-on conditions inline (the safe-exit visibility surface). Per-OQ content moved verbatim; all 62 inbound links stay valid (none used anchors). README's curated OQ summary dropped (now redundant with the index tables). Also seeds tasks/architecture/ with this task plus two follow-ups found during the decompose: OQ-09/10 missing structured Blocked-on fields, and the tasks/architecture/ blocker-task half of the Safe Exit protocol being unenforced.

# OQ-44: Terminal Modes (TTY modes)
|
|
|
|
- **Origin**: `docs/research/alknet-tty/phase-0-findings.md` OQ-TTY-02;
|
|
[crates/tty/tty-backend.md](crates/tty/tty-backend.md)
|
|
(`TerminalParams.modes` field).
|
|
- **Status**: deferred(scope)
|
|
- **Door type**: Two-way
|
|
- **Priority**: low
|
|
- **Blocked on**: a concrete mode-control use case (a deployment that
|
|
needs to set echo/raw/canonical/etc. modes on a PTY, beyond the backend's
|
|
defaults).
|
|
- **Resolution**: Not yet decidable. SSH's `pty_request` carries TTY
|
|
modes (echo, raw, canonical, etc.) as a packed bitmask. The common
|
|
case is "default terminal modes" — the `modes` field in
|
|
`TerminalParams` is `serde_json::Value` (reserved as `{}` in v1) for
|
|
when a concrete use case requires mode control. The backends
|
|
(`portable_pty`, docker `tty: true`, russh `pty_request`) all have
|
|
defaults that work for the common terminal case. Adding mode control
|
|
is additive (extend the `modes` JSON shape) and does not break
|
|
downstream; the decision is deferred until a use case forces it.
