2026-07-09bsp(ch32): naked fsdev ISRs so nested USBD IRQs return safelyhathach
The three USBD lines nest under QingKe HWSTK; gcc's interrupt prologue corrupts the return, so rely on the hardware stack and bare mret. Co-Authored-By: Claude Fable 5 <[email protected]> Claude-Session: https://claude.ai/code/session_01HeF2gZ1M7GWkz6Av4BpKPg

2026-07-09dcd(nrf5x): errata 199 DMA workaround + iso alloc/activatehathach
USBD drops tasks during EasyDMA without the 0x40027C1C latch (anomaly 199); matches the nrfx reference driver. Co-Authored-By: Claude Fable 5 <[email protected]> Claude-Session: https://claude.ai/code/session_01HeF2gZ1M7GWkz6Av4BpKPg
2026-07-09dcd(ip3511): iso alloc/activate; retire armed buffers via EPSKIPhathach
Clear Active before Stall so a queued endpoint actually halts (UM11126 41.8.1); use the sanctioned EPSKIP+wait sequence for stall/reopen/activate. Co-Authored-By: Claude Fable 5 <[email protected]> Claude-Session: https://claude.ai/code/session_01HeF2gZ1M7GWkz6Av4BpKPg

2026-07-09feat: Claude Code multi-agent dev/test harness for TinyUSBhathach
Add worker agents (builder, port-dev, driver-reviewer, hil-operator, pr-monitor), deterministic workflows (validate, fanout-dev, driver-review, hil-validate, full-check, pr-babysit) and a /pre-pr gate skill, so sessions can fan build/test/review/PR-triage work out to tiered subagents. pr-babysit drives a PR to green: triage CI + bot reviews, fix validated findings, verify, push, and reply-to + resolve each inline review thread (fixed or refuted). Replace the stop-the-runner HIL discipline with per-board flock locks: test/hil/board_lock.py plus a fail-open guard in hil_test.py let CI and dev sessions share the rig per board (locked boards fail fast and re-run; HIL_NO_BOARD_LOCK=1 is a user-authorized bypass). The actions-runner is never stopped. Design spec, implementation plan, and real-rig smoke evidence under docs/superpowers/.

2026-07-07docs(AGENTS): prefer git worktrees for branch/multi-step workhathach
Direct agents to work in a git worktree rather than switching the shared primary checkout's branch. Concurrent sessions share that checkout, so a mid-flight branch switch disrupts the other sessions and can silently point a review, build, or commit at the wrong diff. CLAUDE.md is a symlink to AGENTS.md, so both pick this up. Co-Authored-By: Claude Opus 4.8 <[email protected]> Claude-Session: https://claude.ai/code/session_01HeF2gZ1M7GWkz6Av4BpKPg
2026-07-07gate acm_open descriptor bounds behind CFG_TUH_VALIDATION_LEVELJavid Khan
add a three-level TUSB_VALIDATION_NONE/BASIC/STRICT knob and default CFG_TUH_VALIDATION_LEVEL to BASIC, then make acm_open the first user so the enumeration bounds checks compile out at NONE for trusted-device setups and stay on by default.

2026-07-03add ncm receive-path fuzz harness with out-of-bounds seedJavid Khan
folds the reproducer for the recv_validate_datagram bound into a small self-contained fuzz target. it feeds a raw ntb straight into the validator (the driver is pulled in so the static function is reachable) and ships the crafted 64-byte ntb as a seed. the seed trips an asan heap-buffer-overflow against the unpatched driver and is rejected cleanly with the wLength bound in place.

2026-07-01hcd(max3421): improve CHIPRES reset logic and refine oscillator ↵hathach
stabilization timing
2026-07-01max3421: prevent USB host hang at startupMikey Sklar
On some boards the MAX3421E doesn't report its oscillator ready after a soft reset (CHIPRES), so hcd_init() waits on USBIRQ_OSCOK forever and the host hangs at startup before any USB device can be used. Bound the wait so it proceeds after a timeout; it is a no-op where OSCOK arrives normally. Needed on the Adafruit Feather ESP32 V2 (classic ESP32) + USB Host FeatherWing, which otherwise hangs on essentially every cold boot. Relates to adafruit/circuitpython#10053.
