sync_merge.dart declared its own `const _syncDeviceId = 'phone'`, which was
unconditional -- so the desktop web build wrote records under
`diet-guard-sync/devices/desktop/` while every HLC string inside them ended
in `-phone`. The path segment came from the conditional-export constant, the
HLC did not.
Import `syncDeviceId` from github_client_factory.dart instead, so both halves
come from the same source: 'phone' on Android, 'desktop' on web, matching the
Python side's 'pc' in _constants.py.
Preventive, not a repair: there is no devices/desktop/ in the live RTDB yet,
so no already-written record has the mismatch. HLC tie-break is
nodeId.compareTo, so desktop stamps now sort below phone's rather than tying;
entryHlc is deterministic from entry.time and the bodies are identical for a
given entry id, so this changes which identical copy wins, never what data
survives.

A Duration is an absolute span, so stepping a local DateTime by
Duration(days: 1) moves 23 or 25 hours across a DST boundary and lands on
the wrong wall-clock day. Under Europe/Warsaw, spring-forward 2026-03-29:
lastCompleteDay(2026-03-30) -> 2026-03-28 23:00, the day before
yesterday, not yesterday
weeksAgo: 1 from 2026-04-01 -> 2026-03-24 23:00, a Tuesday, so the
wrong ISO week entirely
a 03-27..03-31 period -> emits four day keys, silently dropping
2026-03-31
The Python half computes all three correctly, because timedelta on a date
has no clock to drift against. So for about two weeks a year the phone and
the PC would report different averages for the same log -- exactly the kind
of device-local divergence the shared-source-of-truth rule exists to stop.
Passing out-of-range components to DateTime's constructor normalizes on the
calendar (day 0 is the previous month's last day), which is what timedelta
already does. The same fix goes to day_status_service's streak walker: it
had the identical pattern and predates this feature, so a streak that
spanned the clock change could break when it should have held.
None of the existing tests could see any of this -- every fixture date sits
in a DST-free span -- so the regression tests use dates that straddle
2026-03-29 and assert on the calendar day rather than the DateTime, which
keeps them meaningful whatever zone the runner is in. Verified they fail
against the old arithmetic before fixing it.

The calendar already said which individual days went over budget, but not
whether the week as a whole did. A run of small overages reads as four
harmless yellow squares; averaged, it is the thing that actually moves the
needle.
Three rules are load-bearing, and are documented in CLAUDE.md because getting
any of them wrong silently changes what "under budget" means:
- The denominator is logged days, not elapsed days. An unlogged day is not a
zero-kcal day, and averaging gaps in as zeros would make a badly-tracked
week look like the best week of the year.
- The yardstick is the mean of the per-day budgets over those same days,
resolved through BudgetSchedule -- never today's budget, which would
retroactively reclassify past weeks on every budget edit.
- Today is excluded. A half-logged today drags the mean far enough to flip
the band, so every period ends at yesterday.
Band boundaries reuse the calendar's own OVER_BUDGET_YELLOW_CEILING by
import rather than by copy, so a period and its days can never disagree
about what "over" means; that constant loses its underscore to say so.
The MCP get_averages tool returns the average and the band but drops the
average budget, keeping the module's existing invariant that the budget
number never leaves this machine. The CLI, the gate and the phone all show
both, since it is hidden from the network, not from the user.

Four things about the sync settings read wrong on the phone, all of them
left over from when GitHub was the only backend:
- "Connect GitHub" sat on the primary path as a peer of "Connect Firebase",
implying a choice. It is not one: GitHub is the cutover mirror. Its whole
configuration -- device-flow OAuth, owner, repo, client id, PAT fallback --
now lives under "Advanced (GitHub mirror)".
- "Test connection" builds a GitHubClient and calls canAccessRepo(). It has
never said anything about Firebase, so it is now "Test GitHub connection",
and its result messages name GitHub too.
- Once connected, the account still rendered as an editable email box beside
an empty password box, which reads as "you still have to enter this" -- a
connected device looked unconfigured. It now shows the account as text with
a Disconnect button, and the form appears only when disconnected.
Also pins crdt-sync v0.5.1 (from v0.3.0), the shared-config release the
Firebase cutover needs; verified importable under /usr/bin/python3, which is
what diet-guard-gate.service actually runs.
Adds coverage for both Firebase states, which had none: the disconnected form
and the connected read-only display.

The largest consumer moves last on purpose: diet_guard was 71% of all sync
traffic, and both its surfaces (the PC timer and the phone app) share one
prefix, so they move together.
Firebase becomes the primary backend when it is set up, with GitHub kept as a
mirror so a device that has not moved yet still converges. An unconfigured
device keeps syncing exactly as before, which is also the rollback.
Revision tracking is new here. The PC hand-rolled its own pull-merge-push
instead of calling sync_log, so it had none: every tick re-downloaded every
peer's whole food log -- hundreds of KB, 96 times a day -- and re-pushed its
own regardless of change. It now reads one small revision map first, skips any
peer whose hash is unchanged, and suppresses a no-op push. Every sub-sync
(log, budget, food bank, manual bank) takes the client as a parameter, so one
swap covers all four.
The app could not have reached Firebase at all: nothing called saveAccount(),
so loadAccount() always returned null and openFirebase() always returned null.
Settings now has a Firebase section that stores the account in the OS keystore
and signs in immediately, so a typo surfaces on the screen where it can be
fixed rather than as a silently failed background sync hours later. The email
and password never touch the repo -- it is public.
Platform reaches now degrade instead of failing: an unavailable keystore or
application-support directory costs one tick of extra traffic, where before it
would have taken sync down entirely. Caught by `on Object` rather than
`on Exception`, because an uninitialised binding raises an Error.
Verified end to end against the real database, not just in tests: a live PC
sync merged 57 days / 339 entries and put 221 KB of food log plus 97 food-bank
records into Firebase; a second unchanged tick issued zero pushes; and the
Dart client signed in and read back all 339 meals and 97 foods, then completed
a push / publish-revision / suppress-no-op round trip under a throwaway prefix.
diet_guard: 618 tests at 100% branch coverage.
diet_guard_app: 477 tests. Two assertions moved from 4 pushes to 5 -- the
extra one is this device's revision, published after the log so a peer can
never cache "seen rev X" against a log it never received.

Two failures, both pre-existing and both invisible as failures — each
reported only as "did not complete" after stalling the suite.
app/test/keyboard_operability_test.dart awaited writeLog() straight from
the test body. LogStorageService is backed by a FileDocumentStore there,
so that awaits real dart:io, and the fake-async zone never completes it:
the test hangs rather than fails. Seeding now happens inside runAsync
alongside the pumping, which is the only zone where that write can
resolve. The screen's own initState load needs the same real clock, and
pumpAndSettle() cannot be used to wait for it — inside runAsync it waits
on a frame scheduler this screen never reports as idle — so the helper
pumps a bounded number of times instead. 473 app tests now pass in 14s.
scripts/ci_mirror.sh ran bare pytest while python-tests.yml runs it under
xvfb-run. Without a display the gate's real-Tk tests collapse: the focus
ring has nothing to walk, so three TestRealFocusRing tests fail locally
and pass in CI. The mirror was reporting red on a green tree, which is
worse than not mirroring at all. It now uses the workflow's exact
xvfb-run invocation and fails loudly if xvfb-run is missing.
Neither change touches production code: the delete control and its
id-gate were already correct, and the Python suite already passed under a
display (609 passed, 100% coverage).

diet-guard had no APK build at all; releases were not produced. Adds a
standalone release-apk.yml plus the release signing config the app was
missing.
Signing follows the pattern proven in home_inventory: gradle reads
android/key.properties when present and falls back to the debug key when
absent, so local `flutter run --release` is unaffected. CI writes that
file from repository secrets and shreds it afterwards, and apksigner
fails the build closed if a debug-signed APK ever appears.
Only the signingConfig line changes here: isMinifyEnabled, isShrinkResources
and proguardFiles are left exactly as they were.
This repo has no Flutter analyze/test job, so the release job is not
gated on tests — a broken commit still publishes, with the build failing
as the only backstop. Add `needs:` if a Flutter CI job is added later.
versionCode is github.run_number, which is per-workflow-file — this file
must never be renamed, or the counter resets and updates stop installing.

The Log Meal tab did not fit this laptop, and had not for some time. Measured
under a real 1366x768 X server: it required 866px inside a 739px content pane
with every field EMPTY, and 938px with a day of meals logged.
Because the content frame was place()-centred it was sheared at BOTH edges at
once -- the "Diet Gate" title and the slot header (which meal you are being
asked to log) off the top, the calorie headline and the whole dashboard off the
bottom -- with no scrollbar anywhere in the package and nothing to indicate
content was missing. This is a hard lock: overrideredirect, a global grab, VT
switching disabled. Unreachable content is unrecoverable.
Two independent causes, both needed fixing:
- Every font size was handed to Tk as *points*. Tk encodes the unit in the
SIGN of the size, and _gatelock_typography carried a comment asserting the
opposite ("Tk has no separate px/pt distinction"). At ~100 DPI that made
every string ~30% oversized. Negative sizes now; the docstring records why.
- There was no scroll container. build_layout now uses gatelock's
ScrollableSurface, which top-anchors, scrolls by keyboard, and scrolls to
follow focus.
Font sizes alone were not enough: they take the layout to 702px, still over the
571px pane at 1024x600. Both fixes are load-bearing.
The grams/items selector was mouse-only. tk.OptionMenu's Menubutton defaults to
takefocus=0, so ::tk::FocusOK rejects it and it never entered the tab ring --
verified by walking the real ring, which ran Entry -> Text -> Listbox -> Button
-> TNotebook and skipped it entirely. Switching units rescales the whole entry,
so a pointerless user could not correct "250 grams" to "3 items" inside a lock
they cannot leave without logging a meal. It is now two Radiobuttons, which are
in the ring by default and take both Space and Return -- and which post nothing,
unlike a menu, whose grab-stealing is why screen-locker bans OptionMenu on lock
surfaces outright.
Also: the focus ring was invisible (Tk's default is 1px BLACK on #211D1B) and
_build_desc actively inverted it by setting highlightbackground, the UNfocused
ring, so the box outlined while idle and went black the moment it took focus.
Enter now activates buttons (X11 Tk binds only <space>). Text widgets no longer
trap Tab. notebook.enable_traversal() is called, so Ctrl+Tab and Ctrl+PageDown
work. wraplength drops 900 -> 640, the line-length cap, which also stops a
label forcing a 900px-wide layout onto a 1024px screen.
The Flutter app had two controls with no keyboard route at all. Its desktop
target is the web build in a Chrome --app window, so a touch gesture is not a
fallback there, it is the only interaction:
- Deleting a history entry was bound solely to onLongPress. Long-press has no
keyboard equivalent whatsoever. It now has a focusable IconButton; the
long-press stays as a redundant pointer shortcut.
- Calendar day cells were a bare GestureDetector, so navigating to
date-filtered history was pointer-only and invisible to a screen reader.
Now Semantics(button: true) over an InkWell.
Plus: the filter sheet built a TextEditingController inside build() with the
caret forced to end-of-text, so every keystroke discarded it and silently undid
mid-string Home/End/arrow editing. And nothing capped width, so on the 1366px
desktop window prose ran ~180 characters per line (twice the readable limit)
and a four-digit kcal field spanned ~1334px. AppWidth adds those caps.
Tests: the render check is a failing test, not a script -- ruff runs with
--unsafe-fixes, whose T201 fix DELETES print statements, which would silently
turn a diagnostic into a no-op. test_gate_layout_fits.py was verified red on
the pre-fix code ("content 866 in viewport 768 -> NO SCROLL VIEWPORT ->
UNREACHABLE CONTENT") and green after. The Flutter suite gains its first
keyboard-reachability assertions; it previously had ~109 tester.tap calls and
zero checks that anything was focusable.

Four asks, plus the fixes two review passes turned up.
Removals (all unused):
- "Repeat last meal" button, and the reward/temptation-bundling prompt it
was the sole trigger for. Replaced with a post-log progress card showing
kcal against budget, macros, and the adherence streak.
- The multi-item meal builder, on both the gate and the phone. The stored
`components` field stays: nothing writes it now, but historical composite
entries and the food bank still read it and it is part of the wire format.
- Meal photos entirely: 13 files, `imagePath`, the photo filter, the
wrapper's /blobs/ route, image_picker, and the CAMERA permission.
Reminder false alarms had three real causes, all fixed:
- Logging never reconciled notifications, so a reminder sat on screen up to
15 minutes after the meal was logged -- on the phone itself.
- The background check never pulled, so a PC-logged meal nagged forever
until the app was opened. Now mirrors _cli_gate._should_lock: cheap local
check, network only when a slot looks due, then re-check.
- Meals before 08:00 / after 22:00 were attributed to no slot at all. New
slot_for_log/slotForLog clamps them to the first/last slot, byte-identical
across Python and Dart. Deliberately separate from elapsed_slots, which
would otherwise make every slot fall due at 23:00.
Budget history, so lowering the budget stops rewriting the past:
- Forward-only (effective_from, kcal) entries; each day is judged against
the budget in force then. Verified live: setting 2000 left a 36-day
adherence streak and the whole calendar pixel-identical.
- Rides as hist:<date> fields on the existing budget record. crdt_sync
merges per-field over the union of field names and both devices push the
merged log, so a device that predates the feature relays them untouched --
no coordinated rollout, no second document.
- The seed guard tests emptiness, not file presence: _sync can write an
empty history after merging with a pre-feature peer, and a presence check
would then never seed again, silently reclassifying every past day.
One shared source of truth for every piece of data:
- Body weight now travels as its own `weight` CRDT field. Inside `value` it
was collateral damage of whole-map LWW -- any phone budget edit deleted it,
and the protein target with it.
- Both halves of the food bank sync. The curated half (foods added without
eating them) was the last device-local state. The derived half merges with
count as the clock, so LWW means max-count-wins; the log stays
authoritative for membership, because a CRDT union never shrinks and a
peer's stale copy would otherwise resurrect a deleted food permanently.
- Bank adapters honour tombstones, and Dart parses bank records defensively:
a cast failure there is an Error, not an Exception, so one malformed
remote record would have broken phone sync permanently.
_test_guard.py blocks any pathlib write to real user state while pytest is
in the process, whatever conftest is loaded. A throwaway test run outside
the package conftest destroyed a real GitHub token during this work; this
makes that class of accident impossible rather than merely discouraged.

Found via testing todo's app, which shares this theme.dart template and
has a SegmentedButton: neither ColorScheme.dark() constructor call
defined secondary/tertiary (or their container/on- variants), so any M3
widget reaching for secondaryContainer silently falls back to Flutter's
stock Material teal instead of erroring. Confirmed this app has the same
live bug — ChoiceChip (slot selector) uses secondaryContainer implicitly,
and FilterChip's "Any"/"With photo"/"Without photo" chips in the History
filter sheet were rendering in stock teal in production right now.
The shared palette has one accent, not a separate secondary hue, so these
mirror primary; secondaryContainer/tertiaryContainer use line-dark as a
distinguishable-but-subtle selected-state fill.
Verified: flutter analyze clean, 436/436 tests, re-verified identical in
an isolated worktree, and confirmed live: rebuilt debug + release APKs,
installed via adb install -r (no data wipe), screenshotted the real
device before/after (the History filter chips went from teal to warm
gold/tan), then rebuilt and redeployed the desktop package
(install_arch.sh -> pacman -U) and confirmed the running desktop window
renders identically.

Theme.of(context).extension<AppStatusColors>()! crashed in any context
that doesn't build its theme from buildAppTheme() -- which is most widget
tests, since they wrap in a bare MaterialApp(home: ...) rather than the
real app theme. That crash was latent since AppStatusColors was
introduced but only became reachable once main.dart actually started
using buildAppTheme() (previous commit), which is when 27-47 tests
started failing.
Fixed at both call sites (slot_selector_row.dart, day_status_calendar.dart)
by falling back to AppStatusColors.dark instead of force-unwrapping --
production code should never trust every context to fully replicate the
real theme. Also fixed day_status_calendar_test.dart, which asserted
against stale hardcoded Colors.* values from before the theme rewrite;
it now wraps in the real buildAppTheme() and asserts against the actual
tokens, so the assertions mean something again.
Verified: flutter analyze clean, 436/436 tests pass (up from 389/47).
main.dart now builds MaterialApp's theme from buildAppTheme() instead of
ColorScheme.fromSeed(Colors.teal) -- theme.dart existed but was never
actually used until this commit. photo_viewer_screen.dart,
settings_screen.dart, and day_status_calendar.dart's raw Colors.*
literals (Colors.black, Colors.red, Colors.white38, Colors.grey.shade800,
...) now read from Theme.of(context) instead.
Also rewrites CLAUDE.md's Visual Design & Theming section, which
previously contradicted the unified-design-system skill (noise texture,
multi-layered shadows, ColorScheme.fromSeed -- all things that skill
explicitly forbids).
This was the other prerequisite the on-fill/warm-palette fixes actually
needed: theme.dart existing but unwired meant the app was still running
Flutter's default seeded theme.
pubspec.yaml's adaptive_icon_background is a separate literal from
python_pkg/app_icons' own style.BACKGROUND -- the icon regen updated
every generated PNG but missed this one, so the actual on-device home
screen icon (Android's adaptive icon, not the legacy mipmap) stayed on
the old cool charcoal. Caught on the physical device, not by file checks.
testsAndMisc's generator now syncs this automatically going forward.
- theme.dart: warm unified-design-system palette, on-fill for
onPrimary/onError, and inputDecorationTheme/dividerTheme (previously
unset -> every TextField/Divider fell back to Material defaults).
- slot_selector_row.dart: the Snack ChoiceChip had no explicit
backgroundColor/side/labelStyle like the hour chips, so it fell through
to Flutter's own default -- a literal pure-white border.
- Regenerated launcher icon assets (warm charcoal + warm gold accent) via
python_pkg/app_icons.
- Bump gatelock pin to the released v0.1.1 carrying this same palette.
Verified: flutter analyze clean, diet_guard pytest 443/443 @ 100% coverage,
phone-installed APK pixel-checked (Snack chip border, on-fill contrast).
`ci_mirror.sh` -- the pre-push gate -- ran only the Python side: a clean-venv
pytest and `pre-commit --all-files`. Nothing ran the app's suite, and
`.pre-commit-config.yaml` has no Dart hooks at all, so a red `app/` could be
pushed with a fully green gate. It now runs `flutter analyze` and
`flutter test` too, and *fails* rather than skips when `app/` exists but
flutter is missing: a gate that quietly passes without its toolchain is the
same as no gate. Verified by breaking a Dart file on purpose and watching the
push gate refuse it.
app/README.md was still the stock "A new Flutter project" template. It now
says what the two targets are, why there is no `linux/`, what the wrapper
owns, why the port and Chrome profile are fixed, and which behaviours the
desktop genuinely gives up.

The IndexedDB stores are the desktop device's primary copy of the food log and
the *only* copy of its photos -- photos never sync -- and their wrapper-mirror
fallback is what makes a wiped Chrome profile recoverable. All of that was
invisible to the suite: the files import `idb_browser.dart`, which cannot be
imported outside a web compile, so they were simply absent from the VM test
run rather than covered.
Splitting the store classes from the browser-factory `open…()` functions lets
them run against `idb_shim`'s in-memory backend on the plain VM, which is what
the flutter-desktop-to-chrome skill recommends the shim for. Twelve tests now
pin the round-trip, the mirror write, the recover-from-mirror path, and the
no-wrapper-running case (a plain browser tab, where the app must still work).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Completes the move: `linux/` is gone, replaced by the web build served by the
wrapper in a Chrome `--app` window. The icons and the .desktop installer move
out of `linux/` first -- they are not Flutter scaffolding and are still
needed; the entry now points at the packaged launcher and matches the
`--class=diet_guard_app` the wrapper passes, so the taskbar shows the app's
icon rather than a browser's.
install_arch.sh carries over the three traps each of which produced an
install that looked fine until launched: `dart build cli` rather than
`dart compile exe` (which refuses any package whose dependency graph has
native build hooks), `options=('!strip')` (makepkg would otherwise discard
the AOT snapshot, leaving a binary that runs as the bare Dart VM printing a
usage message), and no browser in `depends` (this machine's policy uninstalls
`chromium` seconds later, failing dependency resolution).
Also adds the frame-cadence instrument the performance claim is measured
with, armed by `--dart-define=DIET_GUARD_FRAME_STATS=1` and read with
`String.fromEnvironment` -- `bool.fromEnvironment` only accepts the literal
`true`, so `=1` would evaluate to false and a whole run would silently
produce no data. It reports frame-to-frame cadence rather than build/raster
durations, since work that fits the budget says nothing about the frame rate
actually achieved.

A browser cannot touch the filesystem, so the desktop app needs a second
half. This local process serves the built web assets, owns an on-disk copy of
every document and photo blob the app stores, and performs the GitHub I/O the
page cannot.
Both GitHub responsibilities are load-bearing, not convenience:
- the device-flow endpoints (github.com/login/device/*) send no CORS headers,
so a page cannot call them at all;
- proxying api.github.com server-side is what keeps the token out of the
browser -- the page is told `{"status":"ok"}`, never the token itself.
The wrapper falls back to the PC gate's existing
`~/.config/diet_guard/sync_token`, so this machine needs no second setup.
Details learned the hard way in the two apps migrated before this one, kept
here deliberately: loopback-only binding (the endpoints overwrite files in
$HOME with no auth), `application/wasm` for .wasm or CanvasKit renders
nothing at all, a fixed port and Chrome profile because IndexedDB is keyed by
origin, and treating a browser exit inside ~5s as a handoff to an existing
window rather than a reason to stop serving. Mirror names are rejected unless
they are plain filenames -- a `..` segment would turn a mirror write into an
arbitrary-file overwrite.

Flutter's Linux embedder manages ~20fps at 3840x2160 -- measured on a stock
`flutter create` counter app, so it is the toolkit rather than this code --
where the same Dart rendered by Chrome sustains ~144fps (evidence in
~/todo/docs/desktop-performance-findings.md). The desktop target therefore
becomes a Flutter *web* build; Android is untouched.
`dart:io` does not fail a web *compile* -- it resolves to a stub that throws
at runtime -- so every platform edge moves behind a conditional export rather
than being discovered later as a blank white window:
- storage: `document_store*.dart`, files on Android and IndexedDB in the
browser (mirrored to the desktop wrapper, which is what makes a wiped
Chrome profile recoverable). Document names stay the exact pre-web
filenames so an installed phone keeps reading its existing log.
- photos: `blob_store*.dart` plus `attached_image*.dart`, since `Image.file`
cannot resolve an IndexedDB key. The picker itself has web support; what
changed is the storage and display model. Camera *capture* is genuinely
lost on desktop -- and photos never crossed devices anyway, `imagePath`
being stripped before push.
- scheduling: `background_tasks*.dart`. A browser has no WorkManager
equivalent -- a closed tab runs nothing -- so the desktop runs an in-page
5-minute check while its window is open. That loses nothing on the PC,
where `diet-guard-gate.timer` already locks the screen on an unlogged
slot, which is strictly stronger than a notification.
- notifications: `notification_backend*.dart`, the browser Notifications API
in place of flutter_local_notifications.
- the GitHub token: `token_vault*.dart`. On web it is *not* held by the
browser at all -- flutter_secure_storage's web backend is WebCrypto-wrapped
localStorage with the wrap key beside the ciphertext, which is obfuscation,
not encryption at rest -- so the desktop wrapper owns it and proxies the
API (`github_client_factory*.dart`).
`Platform.isAndroid` itself throws on web, so every platform branch now tests
`kIsWeb` first; the battery-optimization row (permission_handler, no web
implementation) is hidden off Android.
The desktop pushes under device id `desktop`, not `phone`: sharing an id
would have made the two devices overwrite each other's pushed log on every
tick. The Python side enumerates device directories generically, so it needs
no change.
Tests move onto the same seams -- the file-backed stores keep the atomicity
and unreadable-file guarantees where they belong.

Applies Atomic Habits' two-minute rule: a FAB on the home screen repeats

Adopt the shared icon family (python_pkg/app_icons in testsAndMisc): a
charcoal #1B1D21 field carrying a teal shield-and-cutlery glyph, teal being
this app's own colorSchemeSeed. The fork is paired with a knife on purpose -
a lone three-tine fork reads as a trident at launcher size.
Android gains the adaptive-icon layers the project never had, including an
Android 13 monochrome layer.
Linux needs separate handling: Flutter's GTK runner never sets a window icon,
so my_application.cc now calls gtk_window_set_icon_name and
install_desktop_entry.sh populates the hicolor theme from the pre-rendered
PNGs in linux/icons (committed, so the installer needs no image tooling).
StartupWMClass is the APPLICATION_ID rather than the binary name - verified
with xprop against a running window, where WM_CLASS is the GApplication id.

Both platforms gain a calendar tab/screen (green/yellow/red/not-logged
day coloring, logging/adherence streaks, year-to-date tally), and
tapping a day drills into that day's logged entries. This requires the
daily budget to become a normal, freely-editable value synced between
devices like the food log — replaces the previous chattr +i seal
(deliberately, per user decision) with plain last-edit-wins sync via a
new budget.json alongside food_log.json. The budget field defaults to
2200 kcal, starts read-only, and unlocks via an Edit/Save toggle on
both the PC gate's History tab and the phone app's Calendar screen.

crdt_sync v0.3.0 adds canAccessRepo(), so the settings 'Test connection'
button uses the shared client and the local lib/services/github_client.dart
(+ its test) is deleted. flutter analyze clean, 299 tests pass. On-device
foreground check deferred: the active night curfew disables the app (a
phone-policy thing, not a code issue); build + install -r succeeded.

Immediate push on log only helps when the device is online. If a meal is
logged while offline, the in-process auto-sync fails silently and the meal
waited for the next app lifecycle event. Now each log also enqueues a one-off
WorkManager task constrained to NetworkType.connected, so the log uploads as
soon as connectivity returns, without the app being reopened.
- background_sync_service.dart: backgroundSyncPush() loads SyncSettings and
runs runSync, returning WorkManager's success/retry flag (true when nothing
to push or the push succeeded; false to retry after a transient failure).
Unit-testable half; the dispatcher branch and the one-off registration are
integration-only (real background isolate) and coverage-ignored, matching
the existing periodic check.
- log_meal_screen.dart: _enqueueSyncBackstop() registers the task (replace
policy coalesces a burst of logs; linear backoff retries) from both log
paths. No-op off mobile.
- background_check_service.dart: dispatcher routes the new task name.
- log_storage_service.dart: writeLog is now atomic (temp file + rename) — the
background push's runSync can write the log in a separate isolate while the
foreground app also writes, so a torn read must be impossible.
Verified on device (BL9000EEA0000102): airplane mode on -> log -> background;
airplane mode off -> the phone's remote food_log.json commit advanced within
~15s, app never reopened (also confirms the token loads in the background
isolate).

The phone only pushed its log on screen-init, app resume/pause, or manual
"Sync now" -- never on the log action itself -- so a meal could sit locally
for many minutes before reaching GitHub (and thus the PC gate). Fire the
existing best-effort _autoSync right after a meal is logged, from both the
quick-log path (_onLogMeal) and the meal-builder return (_onBuildMeal), so an
online device propagates a new meal within seconds.
_autoSync is already single-flight and swallows offline/transient failures, so
this is a fire-and-forget unawaited call with no new machinery. Offline logging
still waits for reconnect + a lifecycle event (a WorkManager backstop is a
future follow-up).
Verified on device (BL9000EEA0000102): logging a meal advanced the phone's
remote food_log.json commit within seconds.

CI on main was already red before the crdt_sync migration. Make the
pre-commit --all-files run and the test job green:
- requirements.txt: add crdt-sync (now a runtime dep) and mcp so CI's
`pip install -r requirements.txt` can import diet_guard._sync and
collect test_mcp.py (both were ModuleNotFoundError in CI).
- .pre-commit-config.yaml: add mcp + pydantic to the pylint hook deps so
it can resolve diet_guard._mcp's imports (was E0401).
- pyproject.toml: raise pylint min-similarity-lines to 8 — the shared
nutrition-field keys in _foodbank/_mcp mirror one domain schema, not
real duplicate code.
- scripts/setup_mcp.sh: split declare/assign for SCRIPT_DIR/REPO_DIR
(shellcheck SC2155).
- codespell: fix "packge"/"unparseable" typos; trailing-whitespace
auto-fixes across app/.agents/skills docs.

Replace the bespoke GitHub-Gist sync with the shared crdt-sync /
crdt_sync_dart libraries so diet-guard uses the same CRDT transport as
the other apps.
- Python: delete _sync_github.py (+ its test); rewrite _sync.py,
_cli_sync.py, _sync_merge.py against crdt-sync. Add the crdt-sync git
dependency (pyproject + pylint deps) and S107 to the test ignore list.
- Dart: rewrite app sync_service.dart / sync_merge.dart against
crdt_sync_dart (new git dep + crypto); update log_meal and settings
screens and their tests.
Verification: pytest 347 passed at 100% coverage; flutter analyze clean;
flutter test 306 passed.

gatelock and diet-guard-sync were folded into shared monorepos:
gatelock -> github.com/kuhyx/utils (subdirectory), diet-guard-sync ->
github.com/kuhyx/syncs (subdirectory). Update the gatelock pip URL,
SYNC_REPO_NAME, the devices-dir path prefix (PC and phone), and add a
persisted-value migration so an already-configured phone picks up
'syncs' on next load.

Merge the slot-status bar, slot-selector chips, and "Logging for
HH:00" caption into one selectable, status-colored SlotSelectorRow.
Add an opt-in compact mode to MacroInputRow (single row, abbreviated
labels), AutocompleteSuggestionList (top-3 + "N more" bottom sheet),
and PhotoAttachField (icon-only + badge thumbnail), used only by
LogMealScreen so MealBuilderScreen/EditEntryScreen keep their default
rendering. Verified on-device (BL-9000) that all fields stay visible
with the keyboard open.
Also fixes an unrelated time-bomb in history_screen_test.dart's date
range picker test, which hardcoded an expected "2026-06-01" label
assuming "today" was in June; the picker's displayed month and
selectable range depend on the real current date, so the assertion
now computes its expectation from DateTime.now() instead.

Work-in-progress feature set accumulated ahead of the log-meal compact
layout change: a food bank browser, a shared entry-edit screen, an
app-wide settings service, and a substantially reworked history screen
with filtering/sorting.

The previous commit disabled isMinifyEnabled/isShrinkResources as a crash
workaround (AGP 9 default minification stripped WorkDatabase_Impl's no-arg
constructor). This commit adds the proper fix:
- new android/app/proguard-rules.pro: keeps the no-arg constructor on all
RoomDatabase subclasses (the gap the Room AAR's own consumer rule misses
— it keeps the class name but not the reflectively-called constructor),
plus WorkManager worker/InputMerger rules re-stated from the work-runtime
AAR in case transitive consumer-rule propagation is incomplete through the
Flutter plugin wrapper.
- build.gradle.kts: re-enables isMinifyEnabled=true + isShrinkResources=true
with proguard-android-optimize.txt + proguard-rules.pro.
Verified on the real phone (BL9000): minified release APK launches without
crash, MainActivity foreground, food-bank suggestions and slot chips render
correctly. APK size 52.1 MB (vs 56.9 MB unminified).

M3 – GitHub OAuth device flow: replace PAT-paste with a guided "Connect
GitHub" button that runs the device-code flow; tapping with no client id
now opens a setup dialog (instructions + inline paste field) rather than
a buried inline hint. Bakes in the app's own OAuth App client id so fresh
installs work with zero manual config. Auto-syncs immediately after
connect. Verified end-to-end on the real phone: OAuth flow → token saved
→ PC's 48-entry log merged in (confirmed via food-bank vs manual source
labels in History).
M4 – Background meal-slot notifications: WorkManager periodic task (15 min
floor) checks for overdue slots and posts/cancels notifications via
flutter_local_notifications. New permissions: POST_NOTIFICATIONS,
WAKE_LOCK, RECEIVE_BOOT_COMPLETED, REQUEST_IGNORE_BATTERY_OPTIMIZATIONS,
INTERNET (was missing — latent sync bug). "Disable battery optimization"
button in Settings. Verified on real phone: WorkManager registered, forced
run posted a real notification ("Meal not logged / You haven't logged your
16:00 meal yet."), isolated to background path (only caller is the
WorkManager dispatcher, not any foreground lifecycle hook).
AGP9 release crash fix: AGP 9 defaults isMinifyEnabled/isShrinkResources
to true for release even with no proguard config; R8 stripped
WorkDatabase_Impl's reflection-only constructor, crashing every launch
with NoSuchMethodException. Explicitly disabled both flags in
build.gradle.kts. Verified via dexdump (constructor present) and on-device
launch (no crash). Proper R8 keep rules are the long-term fix; tracked.
177 tests, flutter analyze clean.

Ports github_client.dart and sync_settings.dart from ~/todo (PAT-paste
instead of OAuth device flow), and writes a new (non-CRDT) sync_merge.dart
and sync_service.dart matching diet_guard's Python _sync_merge.py/_sync.py
algorithm exactly. Adds a settings screen for the PAT plus manual "Sync
now", and wires lifecycle-triggered auto-sync (launch + resumed/paused)
into the main logging screen, silent on failure per plan decision 4.
Also adds Linux desktop platform scaffolding so this and future UI changes
can be visually verified without a connected phone.
Verified end-to-end against the real kuhyx/diet-guard-sync GitHub API on a
Linux desktop build: Test connection and Sync now both round-trip to GitHub
and surface real auth errors correctly via SnackBar.

Milestone 2 of the diet-app-as-wise-balloon plan, plus feedback from
manually testing it on-device:
- PhotoAttachService wraps image_picker and copies the picked photo into
<app documents>/images/<uuid>.<ext>, so the file survives after the
picker's own (possibly cache-cleared) temp copy is gone. Phone-local
only, per the sync plan: imagePath is never synced.
- PhotoAttachField is a shared attach/preview/remove widget, used
identically by both the single-item and composite-meal logging
screens, so logging a multi-item meal can now carry a photo too.
- PhotoViewerScreen gives a full-screen, pinch-to-zoom view of an
attached photo -- the 64x64 inline thumbnail was too small to
actually check the photo.
- HistoryScreen lists every logged entry across all days, newest first,
with a thumbnail when one is attached. There was previously no way to
confirm what got logged (or whether a photo actually attached) short
of inspecting food_log.json directly.
Verified on a physical device (BL9000): built, installed, and the user
confirmed the photo-attach flow logs a real entry with a real photo,
visible afterward in the new history list. 88 Flutter tests passing,
`flutter analyze` clean against very_good_analysis.

Milestone 1 of the diet-app-as-wise-balloon plan: a phone-native way to
log meals away from the PC, sharing the exact on-disk JSON shape
diet_guard already uses (same field names, no translation layer).
- lib/models/: 1:1 Dart mirrors of the Python dataclasses (Nutrition,
FoodEntry, MealItem, FoodBankRecord, Slot), including the per-100g/
amount-eaten portion scaling that matches _resolve.resolve_nutrition's
semantics exactly.
- lib/services/log_storage_service.dart: plain-JSON persistence to
food_log.json's exact shape (no sqflite -- the canonical format
already is this JSON).
- lib/services/foodbank_service.dart: ports _foodbank.py's upsert/fuzzy
search logic for autocomplete.
- lib/screens/: log_meal_screen.dart (single-item logging) and
meal_builder_screen.dart (composite multi-item meals, logging full
per-component macros via the new components field).
Verified end-to-end on a physical device (BL9000): built, installed,
logged a real meal through the UI. 77 Flutter tests passing, `flutter
analyze` clean against very_good_analysis.
