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.

diet_guard
A log-to-unlock gate: locks the desktop until a meal is logged once a meal slot (08:00 / 12:00 / 16:00 / 20:00) has elapsed without one, and tracks a sealed daily calorie/macro budget.
Install
bash install.sh
This installs the package + dependencies into system Python's user
site-packages (the systemd service runs /usr/bin/python directly, not a
venv — see CLAUDE.md), installs the systemd user timer, seals your daily
budget, and locks the budget file immutable.
Usage
python -m diet_guard init # one-time: compute and seal today's budget
python -m diet_guard gate --demo # test the lock window (safe, closeable)
The timer runs the gate automatically every ~30 minutes; no manual invocation is needed once installed.
MCP server
An optional Model Context Protocol server
lets an MCP client (Claude Code and its subagents) query today's intake and log
meals as typed tools instead of shelling out to the CLI. It runs in its own
venv (~/.venvs/diet-guard-mcp) so the mcp SDK never touches the
dependency-light system/CLI python path.
Tools:
get_status— today's consumed kcal + macros, the consumption band (on track/approaching limit/OVER BUDGET, or none when no budget is sealed), plus due / logged / current meal slots.list_today— today's logged meals (description, kcal, macros, source, slot).get_slots— the day's fixed meal slots and the current one.log_meal(description, grams=, kcal=, protein=, carbs=, fat=, slot=, confirm=False)— gated write: withconfirm=Falseit previews the resolved nutrition and target slot and mutates nothing; onlyconfirm=Trueappends the entry. The gate is intrinsic — never add this tool to a permission allowlist, since a client's auto-approve mode would otherwise bypass the human confirmation.
The read tools deliberately never expose the raw daily budget number (only the
qualitative band), nor the sealed .budget file, the shared HMAC key, or the
sync token — the budget stays hidden by design.
Setup:
bash scripts/setup_mcp.sh # create the venv and install diet_guard[mcp]
Then restart Claude Code in this repo and approve the project MCP server
(registered in .mcp.json).
Development
python -m venv .venv && .venv/bin/pip install -r requirements.txt
.venv/bin/pre-commit install && .venv/bin/pre-commit install --hook-type pre-push
.venv/bin/python -m pytest diet_guard/tests/ --cov=diet_guard --cov-branch --cov-fail-under=100
