According to WCH FAE transfer complete interrupt is not queued, later completed EP will overwrite INT_ST and RX_LEN.
Which means to guarantee data integrity when multiples EPs are enabled:
- USB IRQ must have highest priority
- IRQ processing time must be less than ZLP duration (~600ns), which is absurd for a 144MHz CPU (85 cycles)

`git worktree add <path> <branch>` fails if <branch> is already checked out
elsewhere (main repo, another worktree). --detach checks out the ref at a
detached HEAD instead of claiming the branch, making the script work
regardless of what is currently checked out.

- run() now catches subprocess.TimeoutExpired (only triggered by `cmake --build`'s
timeout=600) and returns CompletedProcess(rc=124) so the caller falls through to
error reporting and worktree cleanup instead of crashing with a traceback.
- code-size SKILL.md: document the actual default filter (per-side absolute
<checkout>/src/ path, not the old `tinyusb/src` substring) and adjust the
reporting guidance to match what the report rows actually contain.

- Introduced a `code-size` skill under `.claude/skills` for evaluating TinyUSB code size changes between the base branch and current branch.
- Added `metrics_compare_base.py`, automating code size comparison with granular options for examples, boards, and CI-wide runs.
- Updated `AGENTS.md` to include quick references and usage guidance for the new feature.
AGENTS.md:
- fix build dir to cmake-build-<board> (matches hil_test.py expectation)
- reformat flash section to avoid shell-pipe ambiguity, use <board>
- mention board.mk for Make-based builds
- complete OpenOCD jlink interface example
- update stale "Build Option 2" references to "All examples for a board"
- split PVS-Studio command so it is copy-pasteable
.claude/skills/hil/SKILL.md:
- clarify local.json is user-supplied, not tracked in repo
- use python3 consistently
- add all-boards variant for remote execution
- delegate remote execution to test/hil/hil_ci.sh
test/hil/hil_ci.sh:
- portable shebang (/usr/bin/env bash)
- set -euo pipefail
- env overrides for REMOTE, REMOTE_DIR, CONFIG, ROOT_DIR
- --prune-empty-dirs on rsync to skip empty subdirs
- fail-fast sanity check on repo layout

The CI HIL host hits an intermittent USB net interface enumeration race
that fails this test consistently while the device-side build/code is
fine. Disable the entry in device_tests so the rest of the HIL suite can
gate the PR; will re-enable once the host-side flake is addressed.

The CI HIL host repeatedly fails the test with "USB net iface enx... did
not come up with 192.168.7.x within 15s" — USB enumeration + DHCP serve
takes longer there than on the local rig. Bump just this test's timeout
to 30s; other tests stay on the 15s global ENUM_TIMEOUT.

Extract the "which endpoint is the Status stage on" rule into a single
TU_ATTR_ALWAYS_INLINE helper, and use it from both status_stage_xact()
and the completion callback. Replaces the two-operand wLength/direction
check with a direct endpoint-match comparison, matching the first
operand's pattern.
Per USB 2.0 §9.3.1, when wLength == 0 the bmRequestType Direction bit
is ignored and the Status stage is always IN; otherwise the Status
stage is opposite to the Data stage direction.

CFG_TUD_MSC_EP_BUFSIZE: 4096 → (HS ? 4096 : 1024). Keep the big buffer for
HS where it actually amortises CBW overhead at iperf-class throughput; FS
peaks around ~830 kBps so 1 KB is plenty and the example now fits on
small-RAM MCUs (lpc11/13, samd11, kinetis_kl, stm32f0/l0, stm32f1, etc.).
Also dedupe CDC_TX_BUFSIZE = CDC_RX_BUFSIZE.
Drops the previously-needed skip.txt — verified builds locally on
lpcxpresso1347, cynthion_d11, lpcxpresso11u37/u68, stm32f072disco/eval,
frdm_kl25z, stm32l052dap52.

The example uses 4 KB MSC bulk buffer + 2-4 KB CDC buffers to push USB
throughput, which overflows on lpcxpresso1347 (RamUsb2) and cynthion_d11.
Skip the same MCU set as net_lwip_webserver — these targets don't have
the RAM headroom to benefit from throughput tuning anyway.

The bigger TCP_WND/PBUF_POOL/MEMP_NUM_TCP_SEG and the always-on iperf
overflowed SRAM on stm32c0/f1/wb, lpc11/13, samd11. Add LWIP_HIGH_THROUGHPUT
gate (defined in tusb_config.h, consumed by lwipopts.h) so RAM-tight MCUs
keep the original modest buffers and skip iperf, while RAM-rich targets
(max32*/stm32f2/f4/f7/h5/h7/h7rs/u5/n6, rp2040, mimxrt1xxx, nrf5x) keep
the throughput tuning needed for the iperf HIL test.
