More hours of the same room and the same motion add little. Coverage is how Avala plans and proves variety across the dimensions that change what a model learns.

​
Coverage cells

A coverage cell is one combination of six dimensions. Acceptance records the cell values of each capture. The MCP tool get_campaign_acceptance_coverage reports which values are under-covered across accepted captures. A brief sets target accepted hours per cell. A capability experiment lists the cells it targets. Avala plans collection from a public catalog of 175 workflows in 26 task families.

​
Concentration limits

A brief sets the maximum share of accepted hours that any one value can take. Typical limits apply to:
  • one location
  • one operator
  • one appliance or mechanism unit
  • one coverage cell
  • low-variety actions, such as repeated wiping
Avala measures concentration on every delivery. A sequence that would push a value past its limit is held back and reported.

​
Overlap checking

Avala fingerprints the video content of every sequence. Overlap checking runs in three passes:
  1. Exact files. Identical files are caught by hash.
  2. Content fingerprints. Re-encoded, trimmed or cropped copies of the same footage are caught by fingerprint match.
  3. Similarity review. Near-identical scenes from the same place and setup are flagged for a reviewer.
The brief states what each delivery is compared against: the delivery itself, earlier deliveries, or reference footage you provide. Fingerprints are versioned. The coverage report names the version and the scope that were searched.

​
Scene-realism standard

Avala collects real household work in real rooms. The standard has four rules.
  • Keep ordinary distractors. Leave unrelated, safe items in view, such as mail, a phone or adjacent groceries. Nobody clears a whole table to move one bowl.
  • Capture meaningful work. Use natural pace and a real household goal. Slow motion for its own sake, repeated wiping loops, artificial spills and staged piles fail the standard.
  • Vary the whole setting. Spread collection across homes, layouts, operators and appliances. Swapping one utensil or relabeling the same action does not make a new environment.
  • Allow purposeful arrangement. A real request, such as resetting a desk, is valid. Record the starting state, the goal and the result. Do not create disorder to start the task.
Distractors stay in view only when consent, privacy and safety allow it.

​
The coverage report

Each delivery ships with a coverage report. The brief fixes its fields, definitions and thresholds before collection starts. Before delivery, Avala compares the measured mix with the brief. The report lists over-represented locations, operators, appliances and actions next to the missing cells.

Read coverage with the MCP server

The MCP tool get_campaign_acceptance_coverage returns accepted-capture counts per axis value for a capture campaign project. Pass axes as a comma-separated list to choose the axes. Values with low counts show where the campaign is thin. See Use Avala with AI to connect your assistant.
