Every one of these dropped coverage silently - the worst failure mode here,
because the PR still goes green. Found by review, each reproduced first.

Selection rules:

* class_macros derived the config macro from the class DIRECTORY, so a change to
  src/class/midi/midi2_device.c selected the midi_test examples (which do not
  compile it) and never examples/device/midi2_device (the only one that enables
  CFG_TUD_MIDI2, and the only one that does). The file's own macro is unioned in
  where it differs - union, never replace: over-selecting costs a build,
  under-selecting merges a break.
* the ${FAMILY_MCUS} fallback added for espressif fired on any family whose
  _family_mcus came back empty, and _cmake_sets is if()-blind and keeps the FIRST
  definition - so mcx/frdm_mcxn947 answered MCXA15, a token six examples' skip.txt
  names, dropping 12 firmware images CMake builds. Limited now to families that
  never spell set(FAMILY_MCUS ...) at all.
* lib_examples read only an example's top-level CMakeLists.txt/Makefile;
  host/msc_file_explorer_freertos names lib/embedded-cli in src/CMakeLists.txt and
  survived by luck. The whole example tree is scanned. (SEGGER_RTT and rt-thread
  still resolve to nothing: all three references sit inside a LOGGER=rtt guard no
  CI build sets - the documented ruling, not a miss.)
* get_family_boards applied ci_skip_boards/ci_preferred_boards only under
  GITHUB_ACTIONS/CIRCLECI, so the selector answered differently on a laptop than
  on a runner; _prune_buildable forces CI semantics. Its one-board pick also
  abandoned the whole preferred list when entry one could not build the -e set,
  and asked skip_example without the build's -D tokens.
* _config_enables and lib_examples still read with the locale encoding - under
  LC_ALL=C the selector tracebacked on three tracked tusb_config.h files. The
  whole selector and its suite run clean there now.

Workflows:

* the Membrowse Upload step omitted $EX_ARGS, but --one-first now picks the board
  from the -e set, so it configured a different, empty build dir and uploaded
  --identical for a board never compiled. It takes $EX_ARGS for the BOARD; the
  target stays the aggregate, which has no DEPENDS and still records every example.
* blanking FAM_REGEX reset only build_filtered, leaving the build scoped while
  code-metrics took the UNSCOPED branch and diffed a 1-family run against the full
  averaged baseline. All three drop together now, as CircleCI's fall-open does.
* CircleCI's EX_ARGS had no character screen and is used unquoted, and its
  code-metrics job still exit 1'd on an empty metrics set - which a scoped build
  makes a legitimate outcome.
* a `ci-full` PR label now turns the scoping off for one PR. A selector bug
  under-selects silently, and without a label the only ways back to a full matrix
  are accidental.

Performance, since the selector gates every other job: family.cmake texts are read
once rather than per changed directory (a 6,000-file dep bump re-read 84 files
99,892 times) and _scrape_mcu is cached: 2.2s -&gt; 0.29s there, 0.8s -&gt; 0.33s on a
class diff.

Tests: a drift guard for hw/bsp families absent from ci_set_matrix.family_list
(they select zero legs now, where they used to ride the full matrix); the rule-4
port test asserted a SUBSET, which set() satisfies, so it could not fail on the
empty selection it exists to catch; the GITHUB_ENV guard test counted a SUM of two
guards. Drops metrics.py's --only-examples, which nothing called, and applies the
TOTAL scrub to the by-example branch that skipped it.

<title>ci: scope the build matrix and the HIL run to what a PR affects</title>

Every PR built all 74 legs (2494 example builds on GHA cmake alone) and flashed
all 30 rig boards, whatever it touched. One classifier now walks the PR diff twice
and answers three questions: which families to build, which examples per family,
and which boards run which tests. Fail-open throughout - anything no rule
classifies, any exception, any unusable output falls back to the full matrix, and
a master push always builds everything.

test/hil/helper/hil_select.py moves to tools/ci_select.py: it is no longer HIL-only,
and tools/ is where the build side can import it. test_hil_select.py follows it as
test_ci_select.py.

Rules (docs/superpowers/specs/2026-08-19-ci-build-family-filter-design.md holds the
full table): a port selects the families whose family.cmake references it, and its
role - a dcd change skips host examples and vice versa; a class selects only the
examples whose tusb_config.h enables its CFG_TU[DH]_ macro, following cross-class
includes; an example selects itself; hw/bsp selects its family or board; hw/mcu and
lib select whoever references them. CMake is the reference for all of it - make
follows whatever cmake decides, family.mk is never scanned.

Empty means empty (maintainer ruling): a rule that classifies a path to nothing
selects nothing. Ports no family references, classes no config enables, libs no
example builds and hw/mcu paths that resolve nowhere are all real - nothing
compiles them, so nothing can validate them, and the master-push build is the net.
Structural tests pin each such case with an explicit allowlist, so the day one
stops being empty it fails pre-commit instead of silently narrowing CI.

Per-example builds: build.py grows a repeatable -e, resolved against the targets
CMake actually registered and batched into one `cmake --build --target a b c`.
build_utils mirrors CMake's family_filter (the whole FAMILY_MCUS list, ${...} and
string(TOUPPER ...) resolved) for the cmake side, while the make side keeps
master's algorithm verbatim - the two build systems answer differently and a shared
answer breaks lpc54's make link. hil-build gains this even on a full selection:
1702 example builds become 515.

Transport: the selection travels as a file, never an argv or env var - a mass-sweep
diff selects 261 KB against a 128 KiB exec limit, and E2BIG would fail the step
before its own fallback could run. CircleCI carries the example map inside the
generated config (pipeline parameters cap at 512 chars), swapped into the parameter
defaults by sentinel match, and drops the scoping wholesale if that rewrite fails.
Every PR-derived value written to $GITHUB_ENV/$GITHUB_OUTPUT is character-screened.

Code metrics follow the scoping: metrics.py emits per-example totals, and
metrics_pair_compare compares the (board, example) pairs present on both sides
instead of a scoped run against a full-matrix average.

The selector's own suite gates it in both providers: a selector that exits 0 with
valid-but-wrong JSON is the one failure fail-open cannot catch, so a red suite
means the full matrix.

hil, ci: scope HIL builds and tests to the boards a PR affects

Add test/hil/hil_select.py, a stdlib-only selector that maps a PR diff to the
rig boards, tests and BSP families a change can affect, and wire it into CI so
pull requests build and run only those. A port change picks its families' boards,
a class change picks the examples enabling that class, and device/host changes
prune the other role. Anything unclassified — infra, an unmapped port, a selector
error — falls back to the full matrix, and push/schedule runs are untouched.
Move the shared example lists to hil_examples.py; 54 hardware-free tests cover
the rules.</content>

<title>hil: controller-aware scheduling of flash and usbtest concurrency</title>

<link rel='alternate' type='text/html' href='http://cgit.235523.xyz/tinyusb.git/commit/?id=9b3259e60f3bd7e2d9637b61dc07265e4a73b362'/>
<id>urn:sha1:9b3259e60f3bd7e2d9637b61dc07265e4a73b362</id>

Full-fleet profiling (HIL_PROFILE=1 instrumentation, included) showed each
uPD720201 controller's serialized usbtest battery chain dominates wall time,
and a board whose marginal device port bounces during concurrent batteries
can wedge or kill the controller ("xHCI host not responding to stop endpoint
command"). Every such death traced to mimxrt1015's port (its old "kills the
uPD720201" reputation) - it is removed from the config until recabled;
mimxrt1064's enum-retry stalls were a loose device cable (re-seated).
nrf54lm20dk moves to boards-skip until its failing J-Link probe is replugged.
With the hardware fixed both cards run width-4 batteries plus full flash
churn clean, so scheduling stays simple: two symmetric knobs, flashes and
batteries budgeted per controller.

- schedule_boards(): dispatch boards round-robin across host controllers from
  a persisted hint cache (~/.cache/tinyusb-hil/ctrl_cache.json), learned and
  merge-on-write refreshed each run (concurrent HIL jobs keep each other's
  entries). Only the cached PCI address is consumed - dispatch order and
  first-flash budgeting, never battery serialization (batteries resolve live
  or fail closed to an all-slot permit).
- HIL_FLASH_PARALLEL (8) and HIL_USBTEST_PARALLEL (4) are budgeted per
  controller via lock slots assigned on first sight.
- re-runs: a failed run writes &lt;report dir&gt;/&lt;config&gt;.failed with the exact
  re-run spec (--accumulate -b &lt;failed board&gt; -bt &lt;board&gt;:&lt;its failed
  tests&gt;) instead of the inverted --skip-board list of everything that
  passed; --skip-board is gone, --flasher/--exclude-flasher scope a config
  across CI jobs by flasher type (no board names hardcoded in workflows),
  and -a/--accumulate merges a re-run into the existing report. The spec is
  stamped with GITHUB_RUN_ID and cleared on fresh runs, so a retry can never
  consume a spec left behind by a different run's dead or skipped attempt.
- CI: esp-idf firmware builds move out of hil-build into hil-build-esp, and
  the esptool-flashed boards run in their own hil-tinyusb-esp job, so the
  main hil-tinyusb run starts as soon as the fast toolchains finish instead
  of waiting on the slow esp-idf build (an esp toolchain flake previously
  skipped the whole rig run). Artifacts are namespaced per toolchain so the
  esp job downloads only esp-idf binaries.
- HIL_PROFILE=1: timestamped log lines, per-flash durations, permit-wait
  logging, uid-&gt;controller map dump for analysis.
- hil_report: per-variant test duration as a dedicated trailing column,
  recorded only by full runs.

Validated on the ci rig (fixed seeds 20260716/777, full fleet at 8/4):
738s/780s walls with only known-flake failures and no controller deaths,
vs 1134-1211s serialized-battery baseline.
