Study Repo

One repeatable pass that turns "look at <repo>" into scoped, witnessed, license-clean, FILED backlog. When someone drops anything that names a body of code — a GitHub URL, a local checkout, a monorepo subtree, a single file, an npm/pypi/crates package, a paper-with-code / arXiv link, a tarball, a PR/diff, or a bare "study this repo" / "what can we learn from X" / "borrow from <repo>" with no URL at all — this drives the whole flow end to end. Acquire the source into scratch (never the tree) and PIN the commit SHA; read the CODE not the pitch, DEEP by default (fan parallel readers across load-bearing modules + tests + recent commits, then a completeness-critic pass — not a README skim); extract MANY candidate borrows, each grounded at a real source `path:line@sha`; decide borrow-vs-integrate with a license + attribution check; DECOMPOSE into many small independently-shippable tickets (or an epic + child leaves for a track), NEVER one "adopt everything from repo X" monolith; witness each borrow against fak (`fak_feature_query`/`fak index` → PRESENT/PARTIAL/ABSENT), and — the default terminal action — FILE the surviving PARTIAL/ABSENT borrows as gh issues under the right epic. The acquisition/exploration/scoping front-half that FEEDS `field-borrow` (which witnesses+files a single named capability). Distinct from the automated outward `idea-scout` and the kernel-only `sota-check`. Use when handed a specific external repo/codebase/paper to learn from, before filing any "we should adopt X from repo Y" issue, after a competitor open-sources something worth reading, or on a `/loop` cadence over a watch-list.
