## Summary ### Why? The speculation seams being introduced up-stack (path scorer, selector, prioritizer) and durable links from other entities (a path→build mapping) all need to refer to one specific path inside a batch's speculation tree. Restating the full Base/Head split in every seam output couples those contracts to path structure and forces consumers to compare ordered slices; a single opaque identity lets each seam return only what matters — a path ID plus its verdict — and gives durable links a stable key to hang on. ### What? `entity.SpeculationPathInfo` gains `ID`: assigned by the controller when the path entry is first persisted, immutable thereafter, and unique within its tree. Its format is the controller's choice and carries no meaning — it is never parsed. Everything outside the tree names a path by this ID. The tree store persists it transparently through the JSON `paths` column, so the change is additive with no schema migration. ## Test Plan ✅ `bazel test //submitqueue/entity/...` — entity suite passes; the field rides the existing JSON round-trip in the tree store.
