strata19.get_context_measurement
Expert tool
What it does
What context has been assembled recently (which tool, real item count, real token estimate, whether it was a cache hit, staleness in ms — project-wide, not scoped to one work item, since the instrumentation does not record that), plus the ADR-07 five-state freshness (current/stale/superseded/unresolved/invalid) of every asserted edge — an aggregate rollup and, per segment, individually, so a stale segment is visible as stale rather than folded into a count.
When to use it
Use when: "how much context did this cost" · "which segments are stale" · "was this context reused from cache" · "what does the freshness model actually say right now"
Also use when: building the Work > Context surface, or auditing whether staleness is actually visible anywhere before trusting an assembled context
When not to use it
you want to TRIGGER a freshness re-sweep — this tool only reads the last-computed state; a sweep runs as part of reindexing (see asserted-edge-freshness-port.ts)
