Address the root cause of rework-causing hedging: the architect was
put in a logical bind where it couldn't express justified uncertainty
('the pieces exist but the shape isn't clear yet'). The only options
were 'decide now' (premature) or 'deferred(scope)' (false — the
information isn't missing, it's un-synthesized). The agent picked
deferred(scope) with a circular blocking condition (OQ-64 blocked on
OQ-55, OQ-55 needs OQ-64) because there was no honest way to say 'I
can see the pieces but I can't see the shape.'
Changes to the architect role spec:
- Add deferred(unclear) state: the pieces exist but the composition
isn't clear; resolution requires investigation (work through
examples, POC), not waiting. Has an investigation target and an
impacts field.
- Add 'Impacts' field to the OQ format: what does this block
downstream? Be specific ('blocks the first hub deployment because
the hub dials workers' not 'blocks the hub crate'). The triage
signal that makes deferral urgency visible — the field that would
have made the AlknetClient circular hedge visible.
- Add circular-reasoning guard to self-review: 'check that your
blocking condition isn't a prerequisite of the thing you're
deferring.'
- Trim anti-patterns #9-#11 (hedging synonyms catalog, ~40 lines):
detection belongs in the reviewer, not the architect's self-review.
The architect is too close to its own reasoning to see its own
circular hedges.
- Trim door-types section (30→10 lines): keep the one-paragraph
summary, cut the elaboration.
Changes to the architecture-reviewer role spec:
- Add Decision Quality (F) category: false-deferral check
distinguishing three cases — (1) hedging on a resolved decision, (2)
false deferral / circular hedge (the blocking condition is a
prerequisite of the thing being deferred), (3) legitimate deferral.
- Add Impacts Field Coverage (G) category: check that unresolved OQs
have specific impacts fields.
- Note: the Decision Quality category is often the highest-value
check on poorly-defined projects — the architect cannot self-review
it (circular reasoning is invisible from inside the circle).
Retrofit existing OQs:
- Add Impacts field to all 16 unresolved OQs (10 deferred, 6 open).
- Update OQ-63 (TlsError shape) to reflect ADR-087's client-side
addition — the error type now covers both server and client
variants.
- Move OQ-65 (WebSocket carrying channels) to alknet-http theme
(done in prior commit; this commit adds its impacts field).
- Verified: no circular reasoning found in existing deferrals. The
AlknetClient hedge (OQ-64) was the circular one; it's already
resolved by ADR-087.

# 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
|
|
- **Impacts**: None — the `modes` field is reserved as `{}` and backends
|
|
use their defaults, which work for the common terminal case.
|
|
- **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.
