A new OBC opens a guided setup flow. It saves each step so setup resumes after a power loss. The rider can pair a phone, add sensors, set effort zones, or skip the optional parts and ride.

The flow is Hello → Language → Buttons → Units → Theme → QR pairing → Sensors → Zones → All set → Home. It uses the existing 240 × 320 display palette and controls. The settings codec remains versioned. Factory reset removes the phone before it clears settings. If removal fails, the rider can retry. If the Bluetooth controller needs a restart, the screen explains how to finish.

The QR link is https://openbikecomputer.com/app. The screen shows the OBC name and explains when Bluetooth is off or the USB cable prevents pairing. A saved name change refreshes advertising. The same QR screen is available from Settings ▸ Connections. Production link hosting remains #2233.

Public docs changed: yes, in separate docs: commits. The BLE contract defines the link. The guides describe setup and phone removal.

Validation

  • Reviewed the complete device change and its reset, pairing, skip, sensor and persistence paths. A further adversarial review found three pairing/reset defects; this head fixes all three.
  • Rendered all 63 setup frames. Inspected the main flow, language variants, dark theme, sensor scan and value editor. Preserved the existing visual design and copy. Inspected three added recovery frames and accepted only their digests.
  • obc test -p obc-app: 1,197 tests and one doctest pass.
  • obc test -p obc-sim: 74 tests pass.
  • cargo clippy -p obc-app -p obc-sim --all-targets -- -D warnings passes.
  • Board release clippy, release build and resource guards pass. This head uses 1,964,756 image bytes against a 2,019,328-byte limit. Resident RAM is 315,768 bytes. The guarded initialization frame is 1,856 bytes against a 4,096-byte limit.
  • Workspace and board formatting, obc suites check, obc prose --check, and git diff --check pass.
  • The full web browser suite passes: nine tests. Final CI passes on b471dff0b; this PR is merged.
  • Not rerun locally: the full workspace suite and full screenshot sweep. Hardware Bluetooth/reset behavior still needs a physical check.
  • Post-merge requirement audit: all eight listed requirements have no coverage plan and no linked tests. No existing evidence link was affected. No plan update or approval was submitted; their coverage remains Not assessed.

Remaining work

Closes #2215, closes #2216, closes #2217, closes #2218, closes #2219, closes #2220, closes #2221, closes #2222, closes #2223, closes #2224.

Requirements: SYS-045, SYS-046, SYS-047, SYS-048, SYS-049, SYS-052, SYS-060, SYS-063

The device lists Forget phone on the Connections page. The spec and the
board README called it Settings ▸ Bluetooth.

A factory-fresh device now opens first-use setup instead of Home. The
settings blob persists the setup step (VERSION 26, one byte at offset
125), so setup resumes at its step after a power loss. The declared
default is Done: an older blob and every Settings::default() caller
stay set up. Settings::FACTORY puts setup at its first step. The board,
the sim window and the iOS host boot it when the store holds no valid
blob, and the BLE config write starts from it on a blank store.

App::set_settings opens the step's screen over Home, unless a
recovered-ride decision is already on top. A factory reset writes
FACTORY, and its next press goes to setup.

The first step is Hello: the brand signpost on Home's contour backdrop,
"OpenBikeComputer", a greeting in the four UI languages, and one amber
OK. Press ends setup on Home. Setup refuses the escape and the drawers.
The sim gets --fresh, and the sweep gets the setup-hello frame.

Setup now runs Hello, then Language, then Home. The language step is
the Settings Language pick list, wrapped: Select commits the language
under the cursor and ends the step, and Back returns to Hello. A step
moves only the cursor. The tick stays on the committed language.

SetupStep gets Language (byte 2) and an ORDER list. next() and prev()
come from that list, so a new step is one entry there. The blob layout
and VERSION stay. Back persists the step before, so a power loss
resumes on the step the rider sees.

Each titled setup page has a controls hint at its foot: the Up and
Down glyphs with "Choose", and a small amber OK like the one on Hello.
setup::screen takes the settings, so a step opens on the value the
rider already has.

The sweep gets setup-language in four languages and
setup-language-cursor. The copy-fit gate seeds the new screen.

Setup now runs Hello, Language, Units, Theme, then Home. SetupStep
gets Units (byte 4) and Theme (byte 5) and their places in ORDER.

The units step lists Metric and Imperial, each with its symbols
(km · m, mi · ft) under the name. The theme step lists Light and Dark,
each with a swatch of its page in the flag slot. Both steps show two
ride tiles over the controls hint: a speed and a distance, in the
units under the cursor on the units step. The tiles stay at one place,
so the theme step recolours them in place.

The theme step previews the theme under its cursor. App::theme names
the theme a frame draws in: the cursor's theme while the theme step is
on top, else the setting. The frame, the overlays, the map style and
the render key read it, so the whole page redraws in the preview. A
cursor move and Back save nothing. Select commits, as on every step.

The Language list's row becomes rows::choice_row, and its tick
rows::row_tick, so the three pick lists share one row. The sweep is
unchanged outside the new frames.

The sweep gets setup-units in four languages, setup-units-imperial,
setup-theme in four languages and setup-theme-dark. The copy-fit gate
seeds both new screens.

Setup now runs Hello, Language, Buttons, then Home.

The language step speaks the language under the cursor: its title and
its hint follow the cursor. The tick stays on the committed language,
and only Select commits and saves it.

Each titled setup page draws its head through setup::title_bar, which
puts the rider's place in the title bar's right slot ("1/2"). The count
comes from SetupStep::ORDER and starts at the first titled step, so a
new step gets it with no other change.

The button lesson (SetupStep::Buttons, byte 3) puts a signpost board
beside each button, pointing at its flank: Up and Down on the left,
Select and Back on the right. A press fills its board amber. Until all
four are filled, every press only fills, Back and Select included.
Then the page acts as every setup page: Select continues and Back
returns to the language step. The page also teaches one gesture: hold
Back opens the menu from anywhere. Setup still refuses that escape, so
the lesson never triggers it. The foot hint reads "Press each button",
then "Continue" with the OK pill.

The sweep gets setup-buttons and setup-buttons-done in four languages
and setup-buttons-partial. The setup-language frames change for the
step count and the preview. The copy-fit gate walks the lesson to its
filled state.

Setup runs Hello, Language, Buttons, Units, Theme. The units and theme
pages draw the step count in their title bar and use the general hint.

The four boards read UP, DOWN, SELECT and BACK, and the hold tip names
BACK, in every UI language. The board names are literals, so their
catalog keys go.

The first-use setup screen shows a QR code with a universal link,
https://openbikecomputer.com/pair/?s=<16 hex serial>. The app scans for
the OBC Control service, filters on the factory name OBC-XXXX, reads the
open DIS Serial Number String and pairs only on an exact serial match.
The section also sets the QR symbol (version 4, level M, byte mode), the
browser fallback page and the associated-domains file.

Setup now runs Hello, Language, Buttons, Units, Theme, Sensors, then
Home. SetupStep gets Sensors (byte 6) and its place in ORDER, so the
title bar counts out of 5.

The sensors step lists the three slots of the Settings Sensors page:
heart rate, power and cadence. An empty slot says how to wake its
sensor ("Wear the strap", "Spin the cranks"). A saved slot shows its
live status. Under the slots, a row reads Skip, or Continue once a
sensor is saved. Select on a slot opens the Settings scan list for its
kind. A pick there saves the sensor and returns to the step, as in
Settings. Select on the last row ends setup, and Back returns to the
theme step. A cursor move saves nothing.

The scan list opens as SetupSensorScan, the same screen with blocking
caps, so setup refuses the escape on it too. Its empty state now also
says how to wake the sensor, in Settings as well. The sensor status
and scan-hit feeds repaint every screen that declares the
SensorSettings render key, not a fixed list.

The sweep gets setup-sensors in four languages, setup-sensors-added and
setup-sensors-scanning in four languages. The setup frames change for
the step count, and sensors-scanning for the wake line. The copy-fit
gate seeds both new screens.

Setup now runs Hello, Language, Buttons, Units, Theme, Effort, then
Home. SetupStep gets Effort (byte 7) and its place in ORDER, so the
title bar counts to 5.

The effort step (title "ZONES") lists Max heart rate and FTP with
their committed values, then a last row. Select on a value row opens
the drawer editor as a sheet over the page, the same editor the Ride
settings page opens. The editor's Select commits the value and the
settings save follows; its Back discards. Each value can stay "Not
set". The last row reads Skip while neither limit is set, else
Continue, and Select on it ends the step. Back on the page returns to
the theme step and keeps the committed limits. Two ride tiles show
a sample heart rate and power: plain without a limit, in their zone
colour with a limit.

A sheet over a setup page must keep setup's refusals. The chord
refusal and the idle-return exemption now read the base screen, as
the escape already does, so a sheet over a blocking or idle-exempt
screen neither opens another drawer nor times the screen away.

The copy-fit walk ticks once after each gesture, because a sheet a
gesture pushes starts its open on the next tick, and steps 500 ms, past
the 440 ms open. The gate seeds the effort step with both editors.

The sweep gets setup-effort in four languages, setup-effort-editor and
setup-effort-set. The other setup frames change only in the counter.

Setup now runs Hello, Language, Buttons, Units, Theme, Sensors, Effort.
The byte values stay: Sensors = 6, Effort = 7. The title bar counts
out of 6.

Conflict resolutions:
- ORDER holds both steps, Sensors before Effort.
- screen/mod.rs exports and declares both screens and SetupSensorScan.
- setup.skip is in both branches with the same text; one key stays.
  The en comment names the effort title with the other step titles.
- The effort step's cursor uses on_step, as the sensors step does.
- ui_runtime.rs keeps both changes: sensors_screen_up reads the render
  key, and the idle exemption reads the base screen.
- copy_fit keeps the seeds of both steps and the f8 walk timing.
- The flow tests follow the merged order: the theme step opens Sensors,
  the sensors step's last row opens Effort, and the effort step's Back
  returns to Sensors.
- The setup-effort frames pass the sensors step (UP to Skip, then
  Select). Every setup frame is re-accepted for the /6 counter.

The setup scan list draws the Settings scan list body under the step's
title bar and over its hint, through a thin wrapper. The Settings scan
list is unchanged. The sensors step opens its cursor on Continue when a
sensor is already saved. Sensors and Effort share one Skip/Continue row
without a chevron.

Setup now runs Hello, Language, Buttons, Units, Theme, Qr, Sensors,
Effort. SetupStep gets Qr (byte 8) after Theme, so the title bar counts
out of 7.

The pairing step shows the link of BLE spec §9.1 as a QR code: version
4, level M, one byte-mode segment, 5 px modules and a 4-module quiet
zone, 205 x 205 px. The modules are dark on a light square in both
themes. The qrcodegen-no-heap crate encodes it (MIT, no_std, no heap,
no unsafe, no dependencies) into two 138 B buffers in the draw frame.
The serial comes from App::set_serial: the board feeds the FICR device
id that DIS serves, and the simulator feeds the spec's example serial.

The board already advertises its factory name and accepts pairing while
the bond slot is empty, and a factory reset clears a rename. A bond
(set_ble_status with paired) ends the step, also under the passkey
card. A bonded device passes the step by in both directions, because
§9.3 shows the code only while the bond slot is empty.

Back on the code opens "No app": what works offline (map, ride
recording), what needs the app (routes, ride sync), a row back to the
code and Skip. Skip ends the step. Back on that page walks on to the
theme step, so the step before stays reachable. The page is screen
state, not a persisted step: a power loss resumes on the code.

Connections offers "Pair phone" while the radio is on and no phone is
paired. It opens the same code, non-blocking and exempt from idle
return. Back or a bond returns to Connections.

A factory reset now also requests the Forget phone operation, so a
reset device can pair again from setup.

The setup hint names BACK as an outlined key beside the amber OK. The
sweep gets setup-qr and setup-no-app in four languages, setup-qr-dark,
connections-pair in four languages and pair-phone. The other setup
frames change only in the counter, connections gains the row, and the
later setup frames pass the pairing step through Skip. The copy-fit
gate seeds the three new screens. App grows 8 B for the serial.

The companion link guide said that only Forget phone clears the bond.
A factory reset now runs the same removal, so the setup after it can
pair a phone again.

The setup order is Hello, Language, Buttons, Units, Theme, Qr, Sensors,
Effort, and the title bar counts seven titled steps. The setup scan list
keeps its setup chrome and shows 6/7. The sensors step opens on Continue
once a sensor is saved, and the app flow test passes the pairing step
through the skip-app page.

The persisted setup step grows Settings by 2 B. RefCell<LinkControl>
holds a Settings, so ble_object_store grows from 128 B to 132 B with
padding, and ble_total from 24,973 B to 24,977 B. All other named
allocations and ceilings are unchanged.

The pairing code now holds https://openbikecomputer.com/app on every
OBC. The link opens the companion app into its pairing flow, and the
app lists the unpaired OBCs nearby by advertised name. The OBC shows
that name under the code, so a rider with more than one OBC nearby can
select the correct one. The passkey stays the proof of possession.

BLE spec section 9 specifies the link, the symbol (version 3, level Q,
byte mode, mask 6, 185 x 185 px with the quiet zone), the name under
the code, the app flow, the fallback page and the path /app in the
associated-domains file. The serial parameter and its matching rules
are gone.

The symbol is fixed, so pair_code.rs keeps its 29 rows as a const
table and draws them with the same module size and quiet zone. A test
encodes the link with qrcodegen-no-heap, now a dev-dependency only,
and compares every module. The encoder leaves the device image and
the board lockfile and THIRD-PARTY.md drop it.

The name is the stored rename, else the factory name OBC-XXXX, which
the host declares through App::set_factory_name. That replaces
App::set_serial and AppState.serial. The board feeds
identity::device_name(), the sim feeds OBC-7A2F, and
identity::serial() goes back into serial_string().

The five setup-qr frames and pair-phone change. Each decodes to the
link with zbar and OpenCV. App stays 58,448 B; the image is
1,951,604 B, 12,896 B below the setup-step build.

A USB cable parks the radio while the rider's Bluetooth switch stays
on, so no phone can find the OBC. The pairing code then shows "Unplug
cable to pair" in place of the scan line, on the setup step and on the
page that Connections opens. The app reads the interlock as the radio
off with the switch on, which is the only state that gives it.

"Unplug the cable to pair" is 240 px in the caption font, wider than
the 228 px copy width, so the English line drops "the". German, French
and Spanish get their own line.

The copy-fit gate also measures the page with the radio off. The sim
takes --ble off, and the new setup-qr-cable frame shows the line. No
other frame changes.

The English title of the page that Back opens on the pairing code is
now "WITHOUT APP". It has the eleven cells of "GET THE APP", so its ink
ends at x 165 and the 5/7 counter starts at x 192, a 26 px gap. The
other languages keep their titles. Only setup-no-app changes.

The scan list drew every hit from the title bar down, so a fifth hit
ran past the outline in Settings and the fourth ran into the hint band
in setup. The list now draws the window that keeps the cursor on the
panel, down to a bottom the caller gives: the outline in Settings (four
rows), the hint band less 12 px in setup (three rows). The shared
window_start and scrollbar do the scrolling, so the scrollbar shows
when the hits do not fit.

A test renders six hits on both screens, steps the cursor to the last
one and checks that it shows, that the first one scrolled off, and that
no name draws below the bottom. No frame changes: the sensors-scan
frames hold fewer hits than fit.

9,864 B, init_idle frame 1,856 B, image 1,952,188 B of the

When a phone bonds on the pairing step, setup saves the next step as
before, and then opens a PAIRED page in place of the sensors step. The
page shows the success check, "Phone paired", and two lines: the phone
goes on in the app, and this OBC goes on here. The lines use the phone
glyph of the skip-app page and a new OBC glyph with an amber screen.
Select opens the saved step. Back goes to the theme step, because a
bonded device passes the pairing step by. The page is screen state, not
a persisted step: after a power loss setup resumes on the sensors step.

A rejected or failed pairing clears the passkey without a bond, so the
passkey card closes onto the code. This was already the behaviour, and
the tests now cover it on both paths.

From Connections a bond still returns to Connections. The rider opened
the code there, and the phone row and Forget phone now show the bond.
The "goes on here" copy belongs to setup only.

The sim script token P feeds a bond, so the new setup-paired frames
reach the page from --fresh. The copy-fit gate measures the page in
all four languages. No other frame changes.

App and the allocation report are unchanged. The shipping image is
1,954,116 B of the 2,019,328 B slot limit.

Claude-Session: https://claude.ai/code/session_01WFeaY7cFELXdncsXZkwFeB
Setup now ends with an All set page after the effort step. It shows the
device's success check over one line each for the phone, the sensors
and the zones: "Phone paired" or "No phone", the count of saved sensors
or "No sensors", and "Zones set" once either limit is set, else "No
zones". A skipped part draws a dim dash, a done part an ink check.
Select saves setup as Done and opens Home; Back returns to the effort
step.

All set is a persisted step, byte 9, last in SetupStep::ORDER. So the
existing finish and back walk it with no special case, and a power loss
resumes on the page the rider sees. The step counter leaves it out, as
it leaves out Hello, so the counted pages stay 1/7 to 7/7.

The copy-fit gate seeds the page empty and with a paired phone, two
sensors and a limit. The sweep gets setup-all-set and
setup-all-set-full, each in four languages. No other frame changes.
Public docs did not change.

The pairing step's Paired page and the All set page both land. Both sides
added `phone_paired` with the same text; the catalogs keep it once.

The Paired page shows only the check and "Phone paired", centred between
the title bar and the hint. The two "goes on" rows, their strings and the
OBC icon are gone.

The All set hint reads "Let's ride". When the rider skipped a part, a
caption under the summary points to Settings. The summary sits 6 px
higher, so the caption stands apart from the lines.

Changes

First-use setup and pairing

Layer / File(s) Summary
Factory settings and platform wiring
firmware/obc-app/src/settings.rs, apps/obc-sim/*, apps/obc-ios-host/*, firmware/obc-fw-nrf54l/src/*
Factory settings now start setup at Hello. Hosts and simulator instances use factory settings when persisted settings fail and provide factory advertising names.
Setup screens and navigation
firmware/obc-app/src/app.rs, firmware/obc-app/src/screen/*, firmware/obc-app/src/settings/page.rs
The app adds setup screens for preferences, sensors, pairing, effort limits, and completion. Setup progress persists between steps and resumes after restart.
Reset, sensors, cards, and runtime behavior
firmware/obc-app/src/screen/settings/reset.rs, firmware/obc-app/src/screen/settings/sensors.rs, firmware/obc-app/src/ui_runtime.rs, firmware/obc-app/src/card_scheduler.rs
Factory reset waits for bond removal or restart confirmation before committing settings. Sensor scanning follows scan-screen presence. Setup changes card delivery, drawer controls, recovery routing, and escape handling.
Validation and supporting artifacts
firmware/obc-app/i18n/*, firmware/ui-frames.toml, firmware/ui-snapshots.sha256, specs/obc-ble-interface-spec.md, docs/*
Translations, UI snapshots, pairing-code checks, resource measurements, browser assertions, and pairing documentation cover the new flows.

Suggested reviewers: claude

Merge Risk: 🔵 Low · up to 44903

The pairing diagram's visible text omits factory reset as a way to clear the bond, while its screen-reader description includes it. This is a small documentation fix and does not block merge.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 44903

Setup and reset now coordinate stored settings with phone-pairing state. The reviewed paths include safeguards for failed bond removal and saving reset settings, but the controller-clearance behavior after a required restart and the companion app’s device-selection checks remain unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The directly affected authority is the device’s single stored BLE peer and its local settings. The reviewed reset and QR paths do not establish a broader service or tenant exposure.

Trust Boundaries and Controls

  • observed — The QR screen presents discovery information; BLE host status supplies the live passkey and paired result that drive the pairing UI and setup transition.

Resilience and Maintainability Implications

  • inferred — Verified bond-store deletion and a saved factory-settings effect support reset recovery, but an Unconfirmed result does not itself prove that the controller has discarded its in-memory bond before the next boot.

Hardening Proposals

  • proposed — Verify the controller’s post-restart bond state and require a fresh pairing result before treating the device as transferred to a new owner.
  • proposed — Confirm that the companion app treats the fixed QR link and advertised name as discovery data, not proof of device identity or pairing authority.

Full details: Linked Issues check

Explanation

The PR implements the main setup flow, persistence, simulator startup, language/button/unit/theme steps, pairing and no-app paths, sensor and effort steps, completion, factory-reset bond clearing, and related tests for [#2216]–[#2224]. It also adds the pairing-link specification for [#2215]. However, [#2220] requires a version 4, level M QR code with modules of at least 5 px. The changed pair_code.rs uses a version-3, level-Q symbol, and the summary provides no evidence that the module-size requirement is met. The QR test encodes the fixed app link but provides no evidence of the required OBC-identifying payload from [#2215].

Resolution

Change the pairing QR to the [#2220] format and required module size. Encode the [#2215] contract payload that identifies the OBC without carrying a secret. Update the specification, encoder test, snapshots, and resource measurements as needed.

Full details: Out of Scope Changes check

Explanation

The change to apps/obc-web-demo/tests/browser/reading-pages.test.js tightens a sticky-header anchor-position assertion. It addresses an unrelated web-demo scrolling race and has no connection to the linked OBC onboarding, pairing, reset, sensor, effort, or completion objectives. The other summarized changes support those objectives or their automated coverage.

The landing page scrolls smoothly to a fragment. The check passed on
the first sample while the scroll still moved, and the next resize or
fragment jump then interrupted it, so the page stayed at the old
position. The check now waits until the anchor sits under the header.

CI: wasm failed on reading-pages.test.js › "landing anchors stay below the sticky header" (received -1147). This change does not cause it.

  • Same failure on develop: the test also fails on develop (532ef12). Locally it fails in 6 of 12 runs with the same -1147. It failed twice on this head (the first run and one re-run), and it fails intermittently locally on both refs. This PR changes no file under docs/ or apps/obc-web-demo/.
  • Cause, a race in the test: the landing page scrolls smoothly to a fragment (docs/index.html:146). The check top - header.bottom >= -1 passed on its first sample while the scroll was still moving down. The next resize or fragment jump then interrupted the scroll, and the page stayed at y=1147.
  • Fix, ported as 1c34f69: the check now waits until the anchor lands under the header (|top - header.bottom| <= 1). This is also stricter than before. It passed 15 of 15 runs on each ref, and the full browser suite passes 9 of 9.

…t is up

A route or trip card over a setup page led on to a ride, the Route
menu or an escape, and left setup unfinished. The upload family now
waits while setup runs and lands once it ends. The other card families
only pop back to the page under them.

The sensor scan level is now read from the stack: a scan runs while a
scan list is on it. A list that a card or a Root took off the stack
used to leave the scan on.

The reset page kept a "Reset complete / Restarting" page on top. It is
in the settings subtree, so the cleared settings waited there while the
phone was forgotten at once. A power loss on that page left the old
settings beside a forgotten phone, the idle return and the escape led to
Home with setup pending, and nothing restarted.

No port restarts the device from the app, so the hold now writes the
factory settings and opens setup on the same pass. Setup is outside the
subtree, so the save goes out beside the forget. The board opens pairing
again once the bond slot is empty, with no restart. The done page and
its two strings are gone.

A reset during a ride opened setup over the ride, and setup has no way
to the Map or the ride controls. The System page now shows the Reset
door only while no ride records. The page rows read the context facts,
which carry the recording level.

Setup refused every chord, and the quick drawer holds the only power off
and the brightness. Setup pages now refuse only the escape. The quick
drawer opens over them without its Settings control, and the Assistant
chord is refused while setup runs, so nothing in reach leaves setup.
The theme step keeps its preview under the drawer.

The iOS host does not bond, but setup showed its pairing code and
Connections offered Pair phone, and neither could finish. The platform
support's bonding fact now reaches AppState before the input of every
pass. Setup passes the pairing step by and Connections hides the door
when it is false. The iOS host feeds a factory name.

The draw clamps the cursor to a list that refreshed shorter, but Select
read the raw index and picked nothing. The scan list now clamps the
cursor before it handles a gesture.

The setup scan list took the Settings row label as its title. Beside the
step count it was cut in German, Spanish and French ("Trittfrequ..",
"Frec. card..", "Fréq. card.."), and it was in mixed case while every
other setup title is in capitals. Each kind now has a short capital
setup title that fits in all four languages. The copy-fit harness seeds
all three kinds and checks that each title draws whole.

The board offers a recovered ride before it seeds the settings, so setup
waited for the next boot. The iOS host offers it after, and the
recovery card replaced setup. The recovery card's answers now open the
saved setup step while setup is unfinished, whatever the order.

The BLE spec and the board README named Forget phone as the only
device-side clear of the bond slot. A factory reset now runs the same
clear, so both name it.

A blank or invalid slot and a failed read both boot the factory
settings, which start setup, but the log still said "booting defaults".

The persisted setup step bytes now follow the order the rider meets the
steps. Settings v26 is not released, so no blob carries the old bytes.

The resource baseline keeps one note, with the net change against
develop from one head build: App +8 B, the BLE settings cache +4 B.

The root lock keeps develop's resolution of iana-time-zone, and only
adds the QR test dependency. The board comment on bondable links names
the factory reset as a re-pair path too.
