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.

- README: restore the separate CH32V103 / CH583,CH582 rows in the Supported
CPUs table — the merged row wrongly applied "ISO data loss [2]" to CH583/2
- Fix typos in historical changelog entries (santiy, Venndor, dynamnic, bagde,
masstorage, techinical, walkaround, "Update Update") flagged by Copilot
- Replace the AGENTS.md Release section with a pointer to the make-release
skill; add a Finalize step (maintainer commit/tag/push + GitHub release) to
the skill so nothing is lost

Release:
- Bump version to 0.21.0 and regenerate tusb_option.h, library.json,
repository.yml, sonar-project.properties, boards.rst, dependencies.rst
- Add 0.21.0 release notes and split the changelog into per-release files
under docs/info/changelog/ (date out of title, driver/class groups as
sub-headings, DCD & HCD section after Device/Host stacks)
Contributors:
- Credit each release's PR authors in a Contributors section
- Drop the curated contributors page; add MAINTAINERS.rst
Docs:
- Update Code of Conduct to Contributor Covenant 3.0 (keep it in the repo,
remove it from the built docs)
- Sidebar: add a home entry, rename the group to "Documentation", move
Changelog into it, add a GitHub Sponsor button, merge external links,
rename FAQ; hide the inline toctree on the landing page
- Add the make-release skill and update the AGENTS.md release process

Documentation tooling:
- Add the `build-doc` skill and `tools/build_doc.py` wrapper for local
Sphinx builds (clean / -W / open).
- Enable Markdown (MyST) in conf.py and auto-collect
examples/{device,host,dual}/*/README.md into a 3-level Examples nav
(Examples > Device/Host/Dual > example), noting each page's source
location and normalizing headings to a single H1.
- Remove the stale `.claude/commands/build-doc.md`; point the AGENTS.md
Documentation section at the skill.
Example docs:
- Add a README.md for every device/host/dual example: what it does, USB
interface table, notable tusb_config.h settings, generic CMake + Make
build steps, and how to try it.
- Fold each *_freertos variant into its base README, noting the FreeRTOS
source path and any RTOS-specific behavior.
Generated docs/examples/ output is git-ignored. Builds clean with
`sphinx-build -W`.

- Parse PVS_STUDIO_CREDENTIALS into two quoted fields (no glob/word-split).
- AGENTS.md: examples build sets CMAKE_EXPORT_COMPILE_COMMANDS ON already.
Addresses Copilot review on #3695.
- Add --security-related-issues to run_pvs.sh and AGENTS.md analyze commands
so local runs reproduce the CI SAST classification (static_analysis.yml).
- Ignore *.sarif so a successful run leaves the worktree clean.
Addresses Codex review on #3695.
Fix stm32f723disco host HIL: UART RX starvation + DWC2 split bulk NAK/XactErr handling (#3677)
stm32f7 BSP — UART RX starvation
- The host console USART shared interrupt priority with the USB OTG ISR, so a long
OTG interrupt could starve RXNE and drop received bytes. Raise the USART RX IRQ
above OTG_FS/OTG_HS in both the bare-metal and FreeRTOS init paths, guarded by
#ifdef UART_ID so boards without a UART console keep the default OTG priority.
dwc2 host — split NAK/XactErr handling
- Slave mode: a persistently-NAKing split bulk/control IN poll re-armed the
start-split immediately, storming the ISR and starving task context. Throttle by
disabling the channel and re-arming on the resulting halt (no frame deferral).
- Buffer-DMA mode: a pure split bulk-OUT NAK was unhandled, leaving the channel
halted and stalling the transfer — the dominant cause of CDC echo truncation.
Handle it by rewinding the buffer pointers and retrying the start-split
(Programming Guide v4.20a 5.1.4.2).
- Buffer-DMA mode: a split bulk-OUT XactErr was retried immediately, exhausting
HCD_XFER_ERROR_MAX before the transient cleared. Throttle via channel_disable +
re-arm to give the hub TT a recovery gap, mirroring slave mode.
- All three are scoped to split transfers (hcsplt.split_en); non-split NAK/XactErr
keep the core-handled / immediate-retry behavior. The OUT XactErr throttle also
excludes periodic split, where channel_disable() is a no-op and would wedge the
channel. The nak_disabled flag is generalized to retry_disabled and honors
xfer->closing so an endpoint close during a throttled retry tears down cleanly.
Verified on stm32f723disco HIL (slave + CFG_TUH_DWC2_DMA_ENABLE): host/cdc_msc_hid,
msc_file_explorer, and device_info all pass on both variants; DMA CDC echo went
from ~15-25% raw failure to 10/10 clean.
The AGENTS.md '-S src/foo.c' example was inaccurate: -S takes a plaintext
file listing source paths, not paths directly. Drop --dump-files from the
documented commands (it scatters .PVS-Studio.i/.cfg dumps across the tree;
FP-debugging only) and reference the new pvs skill.
https://claude.ai/code/session_015inWmFhRYSq17CxMukdoqX
- 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
