+- Paths are exactly each node's `source` in GRAPH.json@dbe6c0a1; blobs from `git rev-parse dbe6c0a1:<path>`; sha256 over those blob bytes. All three blobs are identical at the frozen Math- cut 9f3fb691.
+- The first two files sit inside the already-bound `eng.hard-gate` tree; per GB-5 a file under a tree needs its own record.
+- Binding is not review, acceptance or status promotion. `math.d5-pin-neighborhood-first-moment` keeps its GRAPH classification; nothing is promoted by this record.
+
+## Sources consulted
+- GitHub Math- history (local clone, objects verified with git). Google Drive not needed: every unit resolved to an in-repo blob at the pin. Dropbox: no access (no connector), not attempted.
+- No Codex-stalled PRs were touched or bound.
+
+## Context from prior agent-1 lanes
+- GB-COV-01 (6367145303, corrected 6368905569): checker counts trees with matching sha as bound.
+- GB-7e (#526): 12 d5 components bound; `math.d5-component.remote-window-proof` deliberately left unbound (shares FC-10 candidate file for `math.rn-fixed-remote-window`).
+- Box test env: `pytest tests` has 10 environmental failures in tests/casefold/test_source_isolation_casefold.py on clean main; unrelated.
