Replace v1 (now archived/USB-IMPLEMENTATION-PLAN-v1-2026-04.md) with a
comprehensive v2 that re-audits every daemon against local/sources/base/
HEAD, aligns with Redox 0.x USB HEAD (Jan-Jul 2026), and reorganizes
phases around bare-metal correctness gaps.
Key v1→v2 corrections:
- xHCI interrupts are *not* restored in production (main.rs:141 hardcodes
Polling). This was the biggest v1 overstatement. P0-A1 now fixes it.
- uhcid/ohcid are 35-line stubs, not "ownership-grade". P0-B2 gives them
real enumeration over usb-core.
- ehcid does not auto-spawn class drivers. P0-B1 adds that.
- The base fork carries only one USB commit. The 88-fix claim lived in
patch carriers that path-sourced recipes don't apply. v2 records this
honestly and recommends per-feature commits on submodule/base.
Also:
- USB-VALIDATION-RUNBOOK.md restored from archived/ (operationally current).
- local/AGENTS.md: operator override allowing agents to create submodules
when really necessary (2026-07-07), with a 4-point necessity test.
- archived/README.md supersession table updated with v1 plan and XHCID plan.
Implements the App side of T5 (toast notifications from the bottom/tlc
synthesis). render_toast() overlay can be wired in a follow-up pass.
- App.toast: Option<String> field
- App.toast_expires: Option<Instant> field
- App.flash_toast(msg): sets toast with 3s auto-dismiss
- App.active_toast(): returns &str if not expired
Key bindings: scrollable help dialog (j/k/PgUp/PgDn/Home/G) wired in
the previous round. dim_backdrop/render_nice_edit/render_open_files
helpers lost to repeated reverts — will be re-added in a clean follow-up.
- udev-shim: replace .expect() with graceful errors (no more panic on Broken pipe)
- P4-initfs: remove duplicate sessiond (conflicted with config)
- accessibility/ime/keymapd: break instead of exit(1) on EBADF
- P6 driver patches rebased
- Docs: archive old reports, add implementation master plan
