Task Vocabulary Convergence

This milestone carried the compiler-checked rename where a mistaken boundary would show up as Rust breakage. It was large but local enough for fresh agents because the source plan gave a clear rule: current generic work becomes task, while the sprint pattern and historical wire names stay stable. The ledger shows it took a retry at the milestone boundary after its child work had already landed, which fits the risk: compatibility and vocabulary had to agree across many Rust modules. The run facts do not attribute the later resolve failure to a task, so the only scoped stress recorded for this milestone is the ledger retry.

This milestone was an editing pass rather than a mechanical substitution. A fresh agent could hold it because the brief gave a classification rule for every occurrence: generic task vocabulary changed, named sprint pattern text stayed, and historical records stayed true. The ledger records retries for this milestone and for its prompt and documentation work, so the stress lived in applying that rule consistently across prose. The gate stayed green after the retries, and no replan is recorded.

This milestone carried the rename into Rails, analysis scripts, and screencast tooling after the Rust and docs boundaries were already established. That made the remaining work manageable for fresh agents: each surface could follow the same rule while preserving stored data and filmed metadata. The ledger shows repeated retries at this final milestone, which is where cross-surface consistency was tested. The recorded merge completed, then a resolve stage failed without task attribution, so the merge boundary still found stress after the task work was green.
