+// The scheduled task card (gHashTag/trios#1550), appended to this file by
+// the same readdir rule as the two blocks above: its subject imports this
+// suite's subject (the store, through useScheduledJobRuns), whose module
+// this file already materialized real behind its own stand-ins - a
+// standalone suite in the subject's group would link the store fresh and
+// trip the generated-graphql document the local run does not carry.
+//
+// The card is held as a FULL SOURCE CONTRACT, no render: its graph also
+// reaches the llm-providers store, whose own suite (lib/llm-providers/
+// storage.test.ts) pins the defineItem interception of ITS OWN storage
+// seam, recorded at that module's first materialization - and bun links
+// and runs test files one by one, so whichever order the two files meet
+// in, a card import from here materializes the providers store first (or
+// replaces it) and poisons that suite's pins. Measured both directions
+// on the first run of this block; the card's own observable answer is
+// effect-gated either way (the run list arrives through effects a static
+// render never runs), so the source checks below are the contract.
