+
+## What this PR is
+- Lane GB-8t per CoS assignment main#475/6369972075; unit list from `docs/retro/RETRO-MATH-BIND-01.slices.json` on main#527 (head e755231e).
+- Data file: `docs/retro/GB-8t.agent2.node-candidates.json` (proposal format, **not** the v2 bindings file).
+- Per the inventory note 6369870497 and GB-5 (#522, e1d1ebc2) Q6, no v2 record is added: none of the 13 units has a node in node_source `d6g8k5htny-coder/Math-:frontiers/downstream_gate_20260925/GRAPH.json@dbe6c0a1b1a22c7404b0fd173ee0043b98a08cde` (49 nodes; 0 reference these paths). `architecture/graph-artifact-bindings.v2.json` is unchanged.
+- Each unit is pinned as `kind: tree` at the Math- cut `9f3fb6918b28e6378c034ebc19e76d432f5391cb`, with the tree sha plus a per-file blob sha and sha256. Implementation files are code inside the unit plus workflows at the cut that mention the unit path, each pinned by blob and sha256. First-add and last-change commits are recorded as provenance.
+- `proposed_node_id` values (prefix `cand.`) are **proposals derived from the path**. They aren't in the graph, and creating them is a separate reviewed GRAPH.json change. They aren't claimed as existing IDs.

+Status: 13 tree-pinned; 0 absent; 0 v2 records added; 13 unbound_artifact; 0 existing-node matches.
+
+## Drive / Dropbox
+- Drive (read-only search) queries: upper2d (title), GP-DATA-114 (title), source smooth realization (title, 0 hits). Title-matching leads are listed as `external_unverified`. Their bytes were **not fetched** and **not imported** under `imports/historical/GB-8t/` (NOT EXECUTED). They are never bound.
+- Dropbox: no access (no connector), and I didn't work around that.
+
+## Checks
+- `tools/graph_binding_check.py --report-only --v2 architecture/graph-artifact-bindings.v2.json --repo d6g8k5htny-coder/Math-=<checkout @9f3fb691>` on main a487cfd4: bound 21, nodes_not_bound 28, stale 0, missing 0, unknown_node 0. This is unchanged from the CoS baseline, as expected for a docs-only proposal.
+- Related tests (test_graph_artifact_bindings_v2, test_graph_binding_check, test_architecture_binding, test_dependency_source_binding, test_architecture_graph_artifact_readback): 115 passed, 1 skipped. The full suite result is in the PR body.
+
+## NOT EXECUTED
+- Drive byte fetch and import; per-unit Drive queries beyond the lane keywords; math content review of any unit; manifest re-verification (left to the owner lanes); checking the Codex-stalled open PRs for further dirs in these families.
+
+Integrator: agent 3 (non-author). Merge commit only. No self-merge.
+
+## Checks (box, CPython 3)
+- `tools/graph_binding_check.py --root . --v2 architecture/graph-artifact-bindings.v2.json --report-only` (with Math- checkout): exit 0 on main `09ae8fd3`. Result: bound 24, nodes_not_bound 25, stale 0, missing 0, unknown_node 0. Same as main, because this PR doesn't touch the v2 file.
+- `pytest -k "binding or architecture or graph"`: 359 passed, 6 skipped (on `09ae8fd3`). Full suite (earlier, on a487cfd4): 1249 passed, 11 skipped, 10 failed. All 10 failures are in `tests/casefold` and reproduce on origin/main in this box, so they're environmental and existed before this change.
