docs(agent): stability+usefulness survey #71 — 2 PROPOSED items

Research iteration (LOOP §1). Findings: the state-file path is robust;
the real stability hole is the eval-only automated lock-bump gate (#14)
with no binary cache, whose true fix is the KVM-blocked #20. Usefulness:
the capture suite lacks a screenshot annotate step. Filed 2 PROPOSED —
an interim build-tier lock gate (no KVM) and a satty annotate step.
V0 (docs-only).

+## 2026-07-08 — Stability + usefulness survey → 2 PROPOSED (iteration #71)
+- **Task:** Bernardo asked to find the next tasks that make the distro more
+  stable + more useful. Research iteration (LOOP §1: write up PROPOSED).
+- **Did:** mapped the module/pkg surface + HARDWARE-QUEUE. Findings:
+  (stability) the state-file path is robust (friendly JSON errors, validate
+  cmd, atomic rebuild on corruption — not a gap); the real hole is the
+  automated lock-bump channel (#14) pushing to `main` on **eval-only** with
+  **no binary cache**, so untested runtime/build breakage compiles straight
+  onto users — the true fix is #20 (VM-suite-in-CI, `[human]`, KVM-runner-
+  blocked). (usefulness) the capture suite is rich but has no screenshot
+  **annotate** step (no satty/swappy); clipboard/emoji/colorpicker/OCR/
+  recording all already ship. Filed 2 PROPOSED: an interim build-tier lock
+  gate (no KVM needed, raises the floor until #20) and a satty annotate step.
+- **Verified:** V0 (docs-only; flake check was green in #70, tree unchanged).
+- **Pending:** Bernardo to triage the 2 PROPOSED into tiers, and — the
+  highest-leverage stability action — decide whether to unblock #20 (register
+  a KVM runner) so the lock-bump channel gets a real runtime gate.
+- **Next suggestion:** if #20 stays blocked, the interim build-tier gate is
+  the cheapest stability win; satty is the cheapest usefulness win.
