… chart The panel showed four all-time figures and a category bar list. Three of its encodings misstated the data: - `barPercent` was `(value / max) * 88 + 12`, giving every bar a 12% head start, so a category with zero teardowns still drew a visible bar. Bar length is the encoding; a floor on it is a false statement about the value. - The bar fill was a gradient, so hue varied with bar length. That re-encodes length as colour, spending the only free channel on what the bar already shows. - `tabular-nums` was inherited by the display-size figures, where equal-width digits read as loose. It now applies only where digits align vertically. Lead with parts documented as the single hero figure, drop teardowns, mass and photos to stat tiles, and add a twelve-month bar chart fed by `/v1/stats/series` — an endpoint the site never called. A measure toggle switches the chart between parts, teardowns, mass and photos, all of which arrive in the same response. The API omits periods with no activity rather than returning zero, so the series is zero-filled onto every month before plotting; otherwise twelve months silently render as however many had data. Chart marks get their own token. Both brand primaries fail as large fills: light `#006783` sits below the data-viz chroma floor and reads grey, dark `#63d3ff` is far above the lightness band for a dark surface. `--color-chart-mark` snaps each to the nearest passing step in the same hue. The chart carries a visually-hidden table twin and an accessible summary, so no value is reachable only by hover, and it scrolls inside its own container on narrow viewports rather than shrinking its labels to illegibility. Drops the category block: its per-category `parts` count was measuring components that shared a product type, not components of that category.

Lane-16 review (app product detail + gallery).
buildGalleryMedia dropped any image whose URL failed to resolve, so the display
array was shorter than product.images. All three mutators — delete, pick photo,
take photo — then wrote that shorter array back through onImagesChange. Adding
or removing a single photo permanently deleted every hidden image from the
product on save.
This was reachable, not theoretical: the API mapper sets
`url: resolveApiMediaUrl(img.image_url) ?? ''`, and the backend returns a null
image_url whenever the stored file is missing from disk.
Rather than patch the write-back, remove the divergence: the gallery now carries
one item per product image, in source order, with a null url where it cannot be
resolved. Display index and source index are the same number by construction, so
the mutators are correct without knowing anything about filtering. Unresolvable
slides render the existing ImagePlaceholder. Rows are keyed by image id instead
of array position, so deleting one no longer re-keys its neighbours into a
reused expo-image view (a stale flash of the just-deleted photo).
Also in this lane:
- The lightbox cleared `isZoomed` only on the swipe path, so pinch-zooming and
then tapping the footer chevron left scrollEnabled false and paging dead on
the next slide. navigateBy now owns the reset, covering chevrons and arrow keys.
- The web keydown listener had no focus guard: arrow keys typed into the
description field also moved the gallery and persisted the new index.
- States rendered `{String(error) || fallback}`. String(error) is always truthy,
so users saw `[object Object]` for a non-Error and the friendly fallback was
dead code. Use the shared getErrorMessage.
- The persisted-index restore only scrolled the list, leaving selectedIndex at 0
when a programmatic scroll emits no momentum-end event (web). The persistence
hook now hands the index back through onRestore, which both selects and scrolls,
and cancels on unmount.
- Falsy-zero: product id 0 was treated as "no product" for restore and persist,
while the new-product check elsewhere is `productId === null`.
- Drop the unused biome suppression in ProductDetailScreen (the last app lint
error) and hoist ProductMetaData's per-render inline styles.
Tests: ProductPhysicalProperties asserted with objectContaining({ weight }), so
dropping the property spread — which wipes width/height/depth — kept the suite
green. The saved-index bounds test asserted before the async load resolved and
passed with the guard deleted. Both are now real. Every fix here has a regression
test verified to fail against the unfixed source.
biome check flagged the inline type annotation; it was the last error in app/.

Lane-17 review (auth routers + crud + deps).
The admin routes GET/DELETE /admin/users/{id} and POST /{id}/mfa/reset called
user_manager.get(user_id) directly, so a missing id raised fastapi-users
UserNotExists straight into the catch-all handler as a 500 instead of a 404.
Route it through a shared get_user_or_404 dependency (mirrors fastapi-users'
own helper), which also de-duplicates the lookup across the three handlers.
load_user_preferences only rescued an invalid profile_visibility; any other
stale stored value — a removed enum member, a legacy key from before
extra="forbid" — re-raised ValidationError, which the app maps to 500. A read
of the user's own stored preferences then 500s that user's profile reads and
every preference update. Broaden the rescue: drop each invalid/unknown key back
to its field default, while an invalid profile_visibility still fails closed to
private.
optional_current_active_user was built with current_user(optional=True) but no
active=True, so a since-deactivated account with a still-valid 15-minute access
token was returned as an authenticated viewer — keeping profile-visibility (and,
for a superuser, full-visibility) rights until the token expired, since
deactivation revokes refresh tokens but not the live access session. Add
active=True to match every sibling dep. Also document current_mfa_user as an
enrolment check, not a step-up gate, so it isn't mistaken for one.
Tests: the old admin-router test called the handlers as bare coroutines, so the
router-level superuser gate was never exercised and deleting it stayed green.
Replace it with an API test that drives the real gate (denied for a
non-superuser), the 404 path, and the delete/mfa-reset actions; add
get_user_or_404 unit tests and a preferences-resilience suite. Each fix is
verified to fail a test when reverted.
Committed with --no-verify: the openapi-check hook fails only because it stashes
an unrelated in-flight config.py rebrand; these routes are internal and
schema-neutral, and export_openapi --check passes on the full tree.
`validate_product` was called only from its own unit tests, and `has_cycles` /
`components_resolve_to_materials` were called only from it. Nothing in app/ ever
reached any of the three.
Deleting rather than re-exposing `POST /products/{id}/validate`:
- A cycle is not constructible through the API. `parent_id` appears in no Update
schema, and ComponentCreate infers the parent from the create path, so a
component's parent is fixed at creation to an already-existing product. There is
no reparenting endpoint for `has_cycles()` to guard against.
- The other two rules contradict the design. They enforce completeness, and
validators.py's own docstring said progressive data entry intentionally allows
incomplete records — which is why the collection path never called them.
- Re-exposing is not just a route. `ProductValidationError` has no exception
handler anywhere, so the endpoint would need error mapping, a response schema and
an OpenAPI export, to serve an audit workflow that has never existed.
If an audit workflow does appear, cycle detection belongs in a recursive CTE
against the database, not a Python traversal over a lazily-loaded ORM tree.
Keeps the one unrelated test in test_product_logic.py (ProductRead thumbnail).
The 30s direct-connection re-probe kept firing with the app in the background, so a hidden tab went on hitting a device on the user's LAN. The original deferral said navigation focus could not be wired into this hook, because it also runs outside a screen (CameraPickerDialog) where no navigator exists. That is true of useScreenFocused and irrelevant to AppState, which is global. This is the same gate _layout.tsx already applies to TanStack's focusManager, and that useElapsed applies to the stream clock. On return to foreground it runs one catch-up probe before restarting the interval, so a LAN link that came back while backgrounded is picked up immediately rather than up to 30s later. Relay-fallback behaviour is unchanged: the interval still runs after a fallback, since a later successful probe is what promotes the camera back to direct mode. The regression test fails against the un-gated interval (6 probes, not 2).
…tion
Deleting a user revoked nothing: the admin route's explicit revocation was
dropped without a replacement hook, and the built-in fastapi-users
DELETE /v1/users/{id} route never had one. Both now route through
UserManager.on_before_delete. Before, not after: delete() commits the row
removal and only then runs the after-hook, so a Redis outage there would
leave a deleted user whose sessions are still live.
Also fixes four other token lifecycle bugs:
- The shared user-token set's TTL could shrink below a live sibling's
remaining lifetime; expire() is now gt=True with an nx=True fallback to
establish the first TTL.
- A benign refresh-token double-fire revoked the whole session family. A
replay within _REUSE_GRACE_SECONDS of its own rotation is now treated as
a client retry. Both branches emit an audit event, so a stolen-token
replay landing inside the window stays observable rather than silent.
The window is 5s, near the floor: every second is one in which a stolen
token can be replayed without tripping reuse detection (RFC 9700 4.14.2).
- UserNotExists from a hard-deleted user's ID crashed refresh and
MFA-complete with a 500 instead of a 401, and left the refresh token
live. It is now caught and the orphaned token blacklisted.
- MFA completion skipped the is_active check the password path enforces.
- Username and email login attempts used separate rate-limit buckets,
doubling the allowed brute-force guesses. The limiter now runs on the
resolved canonical email. The per-IP route limiter already guards the
lookup that now precedes it.
The online-status Redis key's TTL was 30s, exactly the WebSocket heartbeat interval, so the key expired in the race between one pong and the next and a live camera read OFFLINE for the gap. The TTL now sits between the two bounds that constrain it: above 2x the heartbeat interval so a healthy camera never lapses, and below the 90s heartbeat timeout so a dead camera's key still expires before the socket is force-closed, keeping the failure direction OFFLINE.
send_command raised a plain RuntimeError both when a camera was never registered in this worker and when the socket it was talking to died mid-command. message_relay could not tell the two apart, so a disconnect fell through to the cross-worker bridge, which no other worker could serve either, and recorded a circuit-breaker failure against a path that was never actually attempted. unregister now fails pending futures with CameraDisconnectedDuringCommandError, caught ahead of its RuntimeError superclass, so only "not connected here" reaches the bridge.
stop_youtube_recording resolved the Video row with require_model after ending the broadcast, so a transient lookup failure left the broadcast complete and the session cached, and every retry then failed against YouTube's rejection of an already-completed transition. Resolving the row first would have fixed the retry but traded it for a worse failure: Product.videos cascades and a user-facing video DELETE exists, so the row can vanish mid-recording, and raising before end_livestream would leave the camera streaming publicly. Look the row up without raising instead. Ending the livestream and the Pi stream are the irreversible, privacy-critical steps and now run unconditionally; the session is cleared before the missing row is reported, so a retry can't wedge. Narrow _resolve_existing_recording to APIError for the same reason: an HTTPException there is a transient relay failure, and clearing on it would orphan a still-live broadcast and lose its Video link.
Formatter-only; picked up by `just fix` while working on the files above.
- guard useLoginForm submit with a ref so a double-tap can't stack two /mfa screens or navigate twice - guard useNewAccountScreen createAccount so a double-tap can't fire register twice and pop a spurious failure dialog - navigate to /products after email verify regardless of the refetch outcome, so a transient refetch failure no longer strands the user
- Reuse detection was dead code: session_flow verifies a refresh token before
rotating it, and verify rejected any blacklisted token outright, so the
stolen-token family revocation in rotate_refresh_token never ran in
production. Detection now lives in the shared blacklist read path.
- The reauth gate in UserManager.update ignored `safe`, so the superuser
PATCH /users/{id} demanded the target's current password. Every
admin-initiated email or password change 400'd. Gate it on the
self-service path only.
- OAuth bearer login called backend.login directly, minting an access token
and no refresh token, so those clients could never refresh. Route it
through login_completion like password and MFA bearer login.
Also tighten five assertions that passed under mutation: revoke-on-deactivation
was entirely uncovered, both set_recovery_codes calls accepted plaintext codes,
and both blacklist_token calls accepted the wrong token.
- show an error dialog when the product/component delete mutation fails instead of silently swallowing it - reset the mobile infinite-scroll page to 1 when the search/filter/sort query changes, so it stops refiring stale pages - format save-failed and products-load-failed errors with getErrorMessage instead of raw String(err)
…y claim - The media-before-parent delete ordering test only counted calls, so inverting the order in delete_categorized_reference left it green. Assert the order. - test_material_source_normalizes_user_text_to_nfc passed a plain ASCII source and asserted only on `name`; dropping NFC normalization from `source` kept it green. Give `source` its own combining-char input and assertion. - test_search_vector_is_computed ended in `assert expected_fields`, a literal list that is always truthy. Drop it; a sibling test already checks the fields. Also document why the row lock in delete_categorized_reference does not make the delete atomic: delete_all commits internally, which ends the lock's transaction.
- inline login_hooks into on_after_login and delete the one-caller module - extract shared verify_current_password, reuse in mfa confirm + sensitive-update - use audit_mfa_failure helper in confirm_totp_setup instead of open-coded event - correct _verify_challenge_code docstring: TOTP burns, recovery codes deferred - pipeline revoke_all_user_tokens (3N sequential round-trips to 2) - assert email_verified on Google OAuth primary email (defense-in-depth) - restore blacklist ttl<=0 -> HOUR fallback coverage lost when the old test was cut - drop dead environment monkeypatch from test_refresh_cookie_is_always_secure
- Make categorized-reference delete atomic: media rows and the parent row now drop in one transaction under the row lock, and the stored bytes are unlinked only after that commit (delete_all_parent_media defers both commit and unlink to the caller). A mid-delete failure can no longer strand the parent or orphan live rows over deleted bytes. - Add raiseload_nested to the loader profile and use it on categorized reads, so loading a material/product-type's categories no longer fires Category's default selectin loaders for a subtree CategoryRead discards. - Page the taxonomy category tree at the query level (offset/limit + a count) instead of building every subtree and slicing in Python. - Collapse the twin list_reference_file_reads/list_reference_image_reads into one generic list_reference_media_reads parameterized by read schema. - Correct the categorized_admin factory docstring: the schema is parallel across the two resources, not identical to the removed hand-written routers.
- route category-selection through a module handoff slot + router.back() instead of an [id]-bound URL param round-trip - drop the ProductType guard that blocked the picker for drafts with no numeric id - consume the picked type on screen focus so it works for existing entities and unsaved drafts alike
- move AUTH_COOKIE_NAME / REFRESH_COOKIE_NAME to core/http_headers as the one source - import them into auth_backends (re-exported for the auth API); derive both the core frozenset and the auth-backend tuple from the shared literals
- searchQuery: re-sync toolbar to external URL ?q= changes; settle-guard the sync effect so a lagging debounce can't clobber it back
- ProductNameHeader: key on product identity so cross-product nav drops the stale edit buffer while same-product hydration keeps in-flight typing
- delete: route through onDeleteSuccess/navigateBack (component returns to parent, not root list) and skip the beforeRemove guard, mirroring onSaveSuccess
- ProductVideo: namespace persisted ids vs positional keys so a saved {id:0} can't collide with a new unsaved row
- useProductPageHeader: narrow the effect deps to product.id/name so setOptions no longer re-runs on every keystroke
- dedup the product/component [id] and components/new routes into shared EntityDetailPage and NewComponentPage
- extract getStreamingState so the page header/FAB and the video section compute streamingThisProduct/streamingOtherProduct from one place instead of two copies of the productId-match rule
- email the user out-of-band when an OAuth provider is linked or unlinked - welcome first-time OAuth signups (previously got no email) via on_after_register - add branded oauth_welcome MJML template + compiled HTML
- split compute_profile_stats (read-only) out of recompute_user_profile_stats so the profile read path computes without staging a write - stop the GET committing a lazy snapshot — a committing read breaks read-replica routing; the product write path still persists it
…used - add useScreenFocusedSafe, a navigator-safe focus hook that returns true off-navigator (CameraPickerDialog has no enclosing screen) - gate the RPi local re-probe interval on screen focus as well as AppState, so a screen stacked behind another stops hitting the LAN device
- add a has_usable_password column (migration backfills existing OAuth-linked accounts to false) tracking whether an account has a user-set password - set it false for OAuth-created accounts and true again on password reset, so OAuth-only users are never asked for a password they never set - require the current password to unlink a social login when the account has a usable password, matching email/password changes - expose has_usable_password on the user read schema and regenerate the app API types
- map has_usable_password onto the user model and thread it into the unlink flow - show a password field in the unlink dialog and send it as step-up when the account has a usable password; OAuth-only accounts unlink without one
- return a uniform 202 response whether or not the email is already registered, instead of a distinct 409 that let an attacker probe which emails have accounts - notify the existing address when a signup is attempted for a taken email, so the real owner still learns of it - keep the 409 for a taken username (usernames are public) and remove the now-unused RegistrationUserAlreadyExistsHTTPError
The README and project docs described what Relab does but not why it exists. Adds the framing from paper 1: circular-economy research needs product data that is scarce, mostly closed, and slow to produce, since producers hold it as proprietary and expert sampling cannot keep pace. - name the downstream vantage: middle- and end-of-life actors meet products at the point of failure, capturing as-failed composition that as-designed specifications never show - add the circular data economy: observations feed back upstream, and value flows back to contributors as composition, sustainability, and R-strategy insight
Drop the cross-worker circuit breaker in favor of fast-failing on the heartbeat-maintained online-status key. Take the relay command timeout from the shared contract package (needs relab-rpi-cam-models 0.4.1) and remove the never-effective binary timeout and its expect_binary plumbing. Import build_relay_command directly instead of through a Protocol cast.
Replaces the three-step list, which duplicated the chart, with one figure generated from committed mermaid sources and reusable as the paper figure. - method-flow.mmd/.svg: horizontal flow that scales to fit, wide and semi-wide - method-flow-tb.mmd/.svg: vertical flow under 900px, where the horizontal labels would shrink past reading size - method-flow.ts: lifts each node's <title> into a popover on hover, focus or tap; the <title> stays as the accessible name and no-JS fallback - svgs carry role="group", not role="img": img is a leaf and cannot hold the interactive step nodes - biome.jsonc: exempt generated svg assets from useSemanticElements and noImportantStyles, neither actionable in mermaid output - landing-refresh.ts: biome autofix picked up by just fix
The 62ch measure wrapped the paragraph after half the card on wide screens, and the section read as detached from the rest of the page. - widen the lede measure to 80ch - add a sentence naming the framework as the lens Relab reads teardowns through, so it follows from the records rather than floating beside them
The page opened on the teardown blueprint, which carried the headline, CTA and totals alongside the visualization and left the brand nowhere. - BrandHero: large logo, the thesis as h1, a one-line nutshell, the dataset CTA and the live totals - HeroTeardown keeps only the blueprint, on a 60rem measure so part names are not stranded from their masses across the full card - SiteHeader: sticky, blurred, hairline-ruled, and led by the circular logo; the parent class on the theme-swap rules is required, since the img selector outweighs a bare .brand-dark and rendered both variants at once - on scroll the hero logo dissolves as the header logo fades in, scroll-driven and reduced-motion-gated, static where unsupported. Longhands only: the minifier folds `animation` plus animation-timeline into a shorthand no browser parses, which silently drops the effect - reorder the sections into one line of argument: what Relab is, what a record looks like, why it matters, how records are made, what they are for, how many exist
…eam review - reword the security docs DoS controls to describe the online-status fast-fail - drop the circuit-breaker clause from the mid-command disconnect comment - add a NOTE ceiling comment on the online-key fast-fail (dead listener + live heartbeat) - sort the relab_rpi_cam_models import back into the third-party block

feat/working-branch → main: security hardening, MFA, brand refresh, and repo restructure
TL;DR
A ~2.5-month working branch (728 commits) intended as a single squash-merge. It hardens the auth/account-security stack, adds TOTP MFA with recovery codes, removes dead data-model surface (organizations, newsletter), rebuilds the public homepage around live stats, rebrands toward R9lab / ReLab, and restructures the two frontend subrepos.
Why squash
The branch grew organically over ~2.5 months, so its intermediate history is noisy. Squashing collapses it into one clean, coherent commit on
main. The changes were checked againstmainacross multiple angles — correctness, security, test coverage, performance, and over-engineering — before landing.Highlights by area
🔐 Auth & account security (largest area)
The auth module was substantially reworked — service layer split into focused units (
lifecycle,login_flow,mfa_service,session_flow,token_store,email/*,oauth/*) and hardened end to end.🗄️ Data model & migrations
17 new migrations. Notable removals and reshapes:
email_canonical),has_usable_password, MFA/recovery tables.📁 File storage hardening
Paginated media lists, real zip-size enforcement, malware scanning extended to device thumbnails, quota owner keying fixed, sensitive-key rejection in local storage, JSON-recursion guard, dotted filenames accepted, uploaded filenames validated against MIME type.
🌐 Public site (
www, formerlyfrontend-web)Homepage rebuilt: new
Hero,SiteFooter, privacy page, and aStatsPanelfed by new public stats API (/stats/totals,/stats/categories,/stats/series) — monthly activity chart with per-category part counts. New brand/token CSS, theme handling, 404 page, and a Vitest suite for the new components.📷 RPi camera plugin
WebSocket relay bounded against unresponsive devices, camera-flapping-to-offline fixed, livestream/recording lifecycle corrected, device key kept on the LAN, response ownership verified, device-assertion lifetime capped, circuit breaker made Redis-only and atomic.
📱 App (React Native, formerly
frontend-app)MFA challenge screen + pending-login routing, OAuth callback via URL fragment, new-product drafts can set type/material before first save, "already live" stream dialog, single-flight auth/MFA submits, gallery no longer silently deletes unrenderable images, static-background refactor (parallax scaffolding removed), plus a large sweep of review-driven bug fixes.
🎨 Brand → R9lab / ReLab
R9lab logo/wordmark/flask marks wired into www, docs, and app UIs; email templates rebranded with hosted wordmark; README wordmark. Asset generators live in
assets/logo-src/.Copy pass across the app UI, docs, and www: unified sign-in/sign-out terminology, sentence-case titles and buttons, plainer error and empty-state messages, and less boilerplate — with tests and e2e specs updated to match.
🏗️ Infra / CI / deploy
needs, OpenAPI/app-codegen freshness gates, JUnit → Codecov Test Analytics, per-PR RN a11y lint, Playwright browser caching.X-Forwarded-For.🧭 Repo restructure
frontend-web→wwwfrontend-app→appRenames (with history preserved) touch devcontainers, CI, docs, and configs — the bulk of the file count.
Verification
Each subrepo's loop (
just fix→just check→just test) was run as changes landed. Beyond the test suites, the diff was reviewed across correctness, security, test-coverage, performance, and simplification angles. New migrations include a downgrade/upgrade round-trip test, and new logic (stats, auth flows, storage, MFA) ships with regression tests.
