Establishes the tasks/architecture/ blocker-task half of the Safe Exit protocol. Each deferred OQ now has an external-trigger tracker task representing its unblocking condition, and the OQ's Blocked on field names the tracker task ID — closing the gap where the deferral field existed but the task-graph half was unenforced. Changes: - Add 6 external-trigger tracker tasks for the deferred OQs (OQ-09, 10, 32, 41, 44, 46) under tasks/architecture/, tagged [external-trigger, deferred-oq] - Add structured Blocked on field to OQ-09 and OQ-10 (previously used legacy 'deferred' status with the reason in the Resolution prose); index now surfaces all 6 deferred OQs with concrete conditions, no placeholders - Document the architecture-task level mapping (level: implementation for ADRs/specs, decomposition for spec-to-ADR breakdown, planning for backlog seeding, research/review direct fits) and the deferred-OQ blocker-task pattern in docs/sdd_process.md - Mark architecture/safe-exit-blocker-task-mechanism and architecture/oq-09-10-blocking-conditions completed (implemented by this pass) - Fix 4 pre-existing ADR-050 implementation tasks: status: done → completed (taskgraph enum is 'completed', not 'done') — taskgraph validate now passes for all 100 tasks

Description
External-trigger tracker for OQ-44 (Terminal Modes / TTY modes). This is not actionable work — it tracks whether a concrete deployment has emerged that needs to set TTY modes (echo, raw, canonical, etc.) on a PTY beyond the backend's defaults.
Trigger condition
A concrete deployment that needs to control TTY modes beyond the defaults the
backends already provide (portable_pty, docker tty: true, russh
pty_request all have defaults that work for the common terminal case). The
modes field in TerminalParams is serde_json::Value (reserved as {} in
v1) for when this arrives.
What unblocking looks like
When a mode-control use case arrives:
- Mark this task
status: completed. - Move OQ-44
from
deferred(scope)toopen. - Specify the
modesJSON shape (SSH'spty_requestcarries TTY modes as a packed bitmask; the Rust analogue extends themodesfield). Adding mode control is additive (extend themodesJSON shape) and does not break downstream — the architectural commitment is two-way-door.
Why this is a task, not just an OQ field
The OQ's Blocked on: field in open-questions.md is the human-readable
visibility surface. This task is the machine-readable half: it lives in the
task graph so taskgraph tools can reason about it, and so downstream work
that depends on TTY mode control can declare depends_on: [architecture/oq-44-tty-modes-use-case].
Verification
This task is "completed" when a concrete mode-control use case is documented
and OQ-44 has been moved to open.
