# M14-04A Status

status: done
task: Chromium GPU/memory budget device tier selection
updated: 2026-08-19 America/New_York
enablingTask: false
parityStateChange: false

## Scope

Added a bounded device-budget selector driven only by the real Chromium M14-01D identity report.
The observed SwiftShader renderer and unavailable WebGPU adapter select `CONSERVATIVE`; untrusted,
missing, or fallback adapters cannot expand budgets. Fixed `CONSERVATIVE`, `BALANCED`, and `HIGH`
limits are explicit and unknown tiers fail closed. Firefox/WebKit are excluded by the iron rule.

## Evidence

- `npm --prefix web run test:chromium-device-budget` passed: 3 unit tests plus the production identity
  report checker.
- Checker output: `chromium-device-budget-ok tier=CONSERVATIVE reason=UNTRUSTED_ADAPTER identity=3c6f898e1b6ffd39862505b8e7dde8fd29369204e1670a013859f74ccaf1c1eb execution=DISABLED next=M14-04B`.
- `npm --prefix web run typecheck` and `git diff --check` passed.

## Next Task

`M14-04B`: Chromium DPR 1/1.5/2/3 canvas and raycast consistency.
