A re-run attempt merged into an empty base: another PR's HIL job ran
between attempt 1 and the retry and rewrote the shared hil_report.json,
so the run-stamp guard (correctly) refused the foreign base but the
full-fleet results were lost - the retry report contained only the
re-run cells.

Give each (run id, job) its own report dir instead:
- attempts of the same run share a dir, so the retry always finds its
  own sidecar and .failed spec intact
- interleaved runs of other PRs/jobs write elsewhere and cannot clobber
- the run-stamp mechanism (.failed.run file) becomes redundant and is
  removed
- stale per-run dirs are pruned after 2 weeks

<content type='text'>
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.

<title>test/hil: usbtest fleet enablement, shuffled scheduling, unique PIDs</title>

<id>urn:sha1:e02f93158cc602ba6f20945a187172abf2546718</id>

Pool/config:
- record real uids (ra8m1_ek), enable usbtest for espressif s3/p4, then
  park ra6m5_ek and ra8m1_ek in boards-skip (ra6m5's usbtest/MSC traffic
  can kill the uPD720201 host on its ROM firmware; ra8m1 USBHS bring-up
  pending); max32666/nrf54lm20 stay enabled - their MosChip flakiness
  never wedges
- re-enable device/usbtest on HS boards (mimxrt1064, ch32v307) now that
  uPD720201 firmware 2.0.2.6 fixes the command-ring death; mimxrt1015
  stays skipped - its HS battery killed the controller on both ROM and
  2.0.2.6 firmware (board-specific); match the moved host-test bundles
  (f723 &lt;-&gt; rt1064); skip never-passing tests on the new
  nrf5340dk/nrf54lm20dk boards and the detached pico host bundle, each
  documented with a comment

Host-controller quirk gating in usbtest.py (auto-skip, self-heals on a
healthy xHCI):
- MosChip MCS9990 EHCI: case 25 (int-OUT never scheduled, FRINDEX bug)
  and case 11 (unlinked reads complete short/EREMOTEIO)
- Renesas uPD720201 xHCI: firmware-gated. The card must run firmware
  &gt;= 2.0.2.6 (RAM-uploaded - it reverts to ROM on every power cycle):
  on older firmware the command ring dies under unlink stress (a
  Configure Endpoint command stops completing; the hub worker deadlocks
  holding the device lock; only a host power cycle recovers; three
  boards reproduced it). usbtest.py reads the FW version register (PCI
  config 0x6c) and refuses to run at all on older firmware - hil_test
  surfaces that as a failed test with the reason. On current firmware
  the full 30-case battery runs (validated FS+HS: metro_m4, f723,
  f723-DMA all 30/30).

Scheduling (hil_test.py):
- Shuffle each (board, variant)'s test order with a seeded RNG
  (HIL_SHUFFLE_SEED to replay) so usbtest batteries and flash churn spread
  across the timeline instead of convoying on one controller.
- Per-controller usbtest + flash semaphores: HIL_USBTEST_PARALLEL
  (default 4) concurrent usbtest batteries and HIL_FLASH_PARALLEL
  (default 8) concurrent flashes per host controller. Profiled on
  uPD720201 firmware 2.0.2.6 across 8/1..12/8: wall time falls
  22.2/14.3/12.5/10.8 min at usbtest width 1/2/3/4 and plateaus there;
  zero controller errors everywhere; first battery case failures
  (leaf-hub bandwidth stretch) appear at 12/8, and flash width 12 only
  amplifies flasher-hub contention flakes - so 8/4 is the optimum. A
  separate battery-window flash throttle was profiled and dropped.
- Give every example a unique hardcoded USB PID (0x4001-0x4022, usbtest
  keeps 0x4010) instead of the PID_MAP interface bitmap: different
  examples now always re-enumerate back-to-back, even on boards whose
  CPU reset does not drop D+ (WCH CH58x), so the EXAMPLE_PID table and
  same-PID adjacency reordering in hil_test.py are gone; only the
  variant-boundary same-example repeat needs a swap.
- Report matrix: stable columns with the metric-bearing tests pinned
  first (usbtest, cdc_msc_throughput, msc_file_explorer[_freertos]),
  the rest alphabetical.

Fail fast:
- enum wait budget 8 s on the first attempt, 4 s on retries; dfu waits
  are deadline-based so dfu-util's own runtime counts against the
  budget.
  A device-absent failure now costs ~3-5x a passing test (20-30 s)
  instead of 10-30x (47-150 s).
- CI runs hil_test with --retry 1 and no in-run second pass: a broken
  fixture fails the job fast instead of holding the self-hosted runner
  for hours and blocking other PRs' HIL jobs. hil_test still writes the
  .skip sidecar, so a manual re-run attempt only retests what failed.

Review fixes (multi-agent adversarial review of this commit):
- tinyusb_win_usbser.inf: the PID rework moved five CDC examples onto
  even PIDs the INF's odd-only DeviceList never matched (legacy-Windows
  usbser binding) - appended 0x4006/4008/400a/4020/4022 to both lists.
- usbtest example: USBTEST_TIER is now overridable and the descriptors
  and pumps are tier-conditional, so a board whose DCD cannot serve a
  tier lowers it instead of skipping the whole example - RA2A1 (RUSB2
  with no isochronous pipe) builds at tier 3 via its BOARD_ define; the
  host battery follows the tier advertised in bcdDevice. Tier-4 output
  verified byte-identical after the refactor.
- dynamic_configuration's second config derived USB_PID + 11 = 0x4018,
  colliding with net_lwip_webserver - now USB_PID + 0x0100, outside the
  per-example space. tools/check_example_pids.py (pre-commit hook)
  enforces PID uniqueness incl. derived and literal idProduct values.
- usbtest.py firmware gate: matched by device ID (uPD720201/720202,
  both use the 0x6c FW register), and an unreadable version (setpci
  missing/denied) now refuses with its own message instead of
  masquerading as "firmware 0x00000000"; noted the gate is necessary
  but not sufficient (board-specific kills stay per-board skips).
- hil_test: deadline waits use time.monotonic(); multiprocessing
  context pinned to fork (raw semaphores in Pool initargs); flash and
  usbtest permits unified into one fail-closed, exception-safe
  ctrl_permit (unknown controller takes every slot and logs a warning
  instead of silently borrowing slot 0); an all-skipped battery
  reports as skip, not "0/0" failure; slow-body polls (mtp, printer,
  disk read) go through a shared deadline-based wait_until so their
  bodies count against the enum budget; throughput's FS detection
  compares serials case-insensitively like every other walk; a missing
  MSC read-speed line now fails the host msc_file_explorer test
  instead of passing with an empty metric.

Hardening:
- fail fast (15 s) when a driver-registry sysfs write blocks: a wedged
  device otherwise turns every subsequent battery into an unkillable
  D-state writer and silently hangs the whole run
- usb-recover skill: a VM reboot is not a reliable cure (MosChip hubs
  latch up across the PCIe reset); full host power cycle is

* test/hil: replace build.flags_on with named variant schema

Boards declare build variants as `variant: [{name, flags}]` instead of
`build.flags_on`. The variant `name` is the build dir (cmake-build-&lt;name&gt;) and
the HIL report row; `flags` is the raw CFLAGS string (-D...=1) injected via
CFLAGS_CLI. No `variant` =&gt; a single build named after the board.

- build.py: --build-name &lt;name&gt; (dir) + --cflag=&lt;token&gt; (raw CFLAGS, repeatable,
  =form survives the matrix's shell word-splitting); drop -f1/CFLAGS wrapping.
- hil_ci_set_matrix.py: emit one build arg per variant.
- hil_test.py: iterate variants; report row + build dir = variant name.
- hil_ci.sh: copy all cmake-build-&lt;board&gt;* dirs for -b runs.
- get_deps.py: accept (ignore) --build-name/--cflag from matrix args.
- tinyusb.json: migrate all 6 flags_on boards to variant.

The Size Difference Report and HIL comments rendered their titles at h1, which
is oversized inside a PR comment. Use h2 for both titles (with subsections
demoted to h3 to keep the hierarchy), and rename the HIL comment from
"HIL test results" to "Hardware-in-the-loop (HIL) Test Report" for consistency.

hil-hfp-iar runs hil_test.py on hfp.json built with IAR on its own rig. Upload
its report as the hil-report-hfp-iar artifact and add the job to the hil-report
combine job's needs, so the sticky comment shows a third table for the IAR rig
alongside tinyusb.json and hfp.json (gcc). The combine gate now runs if either
HIL job produced results.

hil_test.py persists results in a hil_report.json sidecar and regenerates
hil_report.md from it. A full run starts fresh; a re-run (--skip-board / -bt,
i.e. the .skip file) merges into the existing report so already-passed
boards/tests are preserved while only re-run cells update. The report dir is
configurable via HIL_REPORT_DIR.

build.yml: each HIL rig writes the report to a workspace-sibling dir that
survives the per-attempt workspace clean, and uploads it as an artifact. A new
hil-report job merges the rigs' reports into one sticky PR comment (marocchino)
with one table per rig.

* ci: carry metrics baseline forward on no-code-change pushes

The code-metrics job is gated on code_changed and only uploads the
metrics-tinyusb artifact on push, so a workflow/docs-only push to master (e.g.
removing an unrelated workflow) leaves the latest master Build run without a
baseline. PRs download the baseline from the latest master run, so the size
comparison then finds nothing and silently falls back to absolute sizes.

Add a small metrics-carry-forward job that, on a non-code-change push, downloads
the previous metrics-tinyusb artifact and re-publishes it, so the latest run
always carries a usable baseline. Carry-forward runs re-upload too, so the
baseline chains across consecutive no-code pushes (bounded by artifact retention).</content>
