alvocool 16bff634b5 Initial commit: Grounded Flutter frontend
A to-do app that doesn't believe you — an enforcement layer rather than a
neutral ledger.

Architecture ported from Autoreceptives/Frontend/Receptive: stacked MVVM with
the mandatory 4-file screen pattern, one ParentViewModel owning the loading /
network / error overlays and the handleError decision tree, one AppDataManager
gateway, dio comms carrying the three identity headers, secure storage with
random-suffixed keys, and a single-chokepoint Navigator. Package root and Dart
package name are both Grounded; org is nya.

The enforcement engine, one unit per formula in utils/:

- DebtEngine      w(class) x severity(d) x decay(t), sublinear severity so old
                  misses cannot swamp the score; abandonment 2x with 30-day
                  decay immunity; late complete retains 30%
- StandingEngine  Good -> Warned -> Grounded -> Lockdown, derived not set;
                  Grounded replaces home with the overdue queue
- CapacityEngine  blocks over-scheduling against p50 of historically completed
                  minutes, with a learned per-category estimation multiplier
- IntegrityEngine session integrity, weekly volume, plyometric contact ceiling
                  and enforced recovery gaps
- ExcuseAnalyser  on-device excuse clustering plus the confrontation copy
- GuardrailEngine distress detection and rationed amnesty
- ToneEngine      all enforcement copy, so the tone cap lives in one place

CommitmentEvent is append-only and is the source of truth rather than the
status field, which is what makes honest history and excuse analysis possible.

Goals contain commitments via parentId, and a task can be run from a
full-screen runner that derives elapsed time from wall-clock so screen-off
cannot lose time. Backgrounding pauses the clock and is counted. The runner is
mirrored into an ongoing notification, with alarm-class full-screen intents
reserved for non-negotiables.

Design language, fonts, icon and native splash are in place; Mason bricks are
retargeted to this project and verified end-to-end.

# Grounded — Design Language
Reference: black device chrome, a white content sheet that rises into it with a
large corner radius, oversized light display titles, tiny grey all-caps metadata
labels, pill chips, and a lot of whitespace. The app reads as a record, not a
dashboard.
## Type — General Sans
| Role | Family | Size | Use |
|---|---|---|---|
| Display | `TextType.Light` | 3044 | Screen titles. Always light, never bold. |
| Title | `TextType.Bold` | 1720 | Card and section titles. |
| Body | `TextType.Regular` | 1314, `height: 1.5` | Descriptions, copy. |
| Label | `TextType.Bold` | 1011, `letterSpacing: 0.81.2`, uppercase, `colorGrey2` | Metadata above a value. |
| Metric | `TextType.Bold` | 2434 | Debt score, counts. |
The label/value pair is the core unit: a tiny grey all-caps label sitting
directly above a large dark value. Used everywhere numbers appear.
## Geometry
- Sheet radius `28`, card radius `16`, chip radius `999`, control radius `12`.
- Screen padding `20` horizontal. Card padding `16`. Section gap `28`.
- Hairlines at `colorDivider` (black 7%), borders at `colorBorder` (black 8%).
- One soft shadow only: `0 4 18 rgba(0,0,0,0.03)`. No coloured glows.
## Colour
Near-black ink (`colorPrimaryDark #141414`) on warm off-white
(`colorPrimaryLight #EDEEEA`), with a single green accent (`colorPrimary
#2F6F4E`). Enforcement tiers own the rest of the palette:
| Standing | Colour |
|---|---|
| Good | green `#2F6F4E` |
| Warned | amber `#C98A04` |
| Grounded | rust `#B5442F` |
| Lockdown | oxblood `#7A1F14` |
The tier colour is used consistently — header, chip, meter, queue accent — so
the standing is legible without reading the word.
## Structure
Every screen is: black `headerBar` (back, title, action) → white sheet with a
`28` top radius → `sectionHeader` (label + light display title) → content.
## Rules
- Display titles are Light. Bold is for labels and metrics only.
- Numbers get a label above them, never beside them.
- Chips carry state, never actions.
- One primary button per screen; everything else is outlined or text.
- Empty states are plain. An empty overdue queue is good news, not a party.
