02 / Proof of Work

Show the work. Not the promise.

AI systems become trustworthy when the work behind them can be inspected, tested and repeated.

  1. Input
  2. Process
  3. Evaluate
  4. Evidence

Representative systems we could build.

These illustrative concepts show the kinds of evaluation, data and reliability systems TEXERA LABS is designed to engineer. They are technical examples, not claims of completed client work.

Illustrative project concept01

Model Evaluation Infrastructure

Make model behaviour measurable before it becomes a production problem.

An evaluation system that turns product requirements into repeatable test cases, structured rubrics, failure categories and reviewable evidence.

  1. RequirementsWhat the system is actually required to do
  2. Evaluation setCases that represent those requirements
  3. Model / systemThe thing under test, pinned to a version
  4. ScoringOne rubric, applied the same way every run
  5. Failure analysisCategorise what broke, not just how often
  6. EvidenceA record another engineer can review

Covers

  • Rubrics
  • Benchmarks
  • Regression
  • Failure taxonomy
  • Trace review

Training Data Quality Pipeline

Useful training data is engineered, not simply collected.

A pipeline for sourcing, filtering, annotation, quality review, provenance and versioning so datasets remain inspectable and reproducible.

  1. SourceWhere each record came from, recorded
  2. FilterRemove what does not belong
  3. AnnotateAdd the labels the task actually needs
  4. ReviewA second pass, by someone who did not label it
  5. ValidateAutomated checks against the schema and rules
  6. VersionPin the set so a result can be reproduced
  7. DatasetReleased with its provenance attached

Covers

  • Provenance
  • Annotation
  • Quality control
  • Versioning
  • Review

Agent Reliability Evaluation

Test agents across tasks, states and failure modes.

An evaluation harness for AI agents that records task execution, tool use, intermediate states and failure modes so reliability can be measured across repeatable scenarios.

  1. TaskThe scenario the agent is asked to complete
  2. PlanThe sequence it intends to follow
  3. ToolThe call it makes, with its arguments
  4. ObserveWhat came back, captured verbatim
  5. DecideThe next step it chooses, and why
  6. ActThe action taken against the environment
  7. ResultFinal state, recorded for replay

Steps 02–06 repeat until the task resolves or a terminal state is reached.

Terminal states

  • Success
  • Regression
  • Timeout
  • Wrong tool
  • Invalid output
  • Unexpected state

How a run can end. The harness records which one occurred, and at which step.

Covers

  • Task traces
  • Tool calls
  • State capture
  • Failure modes
  • Scenario replay

Engineering principles

Evidence should survive inspection.

  1. Reproducibility over guesswork.

    A result that cannot be run again is an anecdote. Every evaluation carries the inputs, configuration and versions needed to repeat it.

  2. Failure analysis over surface-level scores.

    An aggregate number hides the cases that matter most. Failures are categorised and read, not averaged away.

  3. Systems over isolated demos.

    A demo shows that something can happen once. A system is what makes it happen dependably, under conditions nobody chose in advance.

  4. Traceable work over opaque outputs.

    Any output should be able to point back at the data, the configuration and the decision that produced it.

Have a system that needs to be evaluated, engineered or made more reliable?
