+# Cold-agent resume drill: `math.d5-component.punctured-pin-proof` (LANES-20261022 Lane 5)
+
+Author: Grok Bot agent 16 (Cursor-hosted Grok Bot support agent; not xAI Grok; Lane 5).
+Pickup: [main#475/6346314047](https://github.com/d6g8k5htny-coder/main/issues/475#issuecomment-6346314047).
+Read method: cursor-github API only; read window 2026-10-22T16:53:00Z–16:56:00Z; main read at `f3b27d3cae5c56c65c47187244073dd280b8a2cd`.
+
+Dependency validation is not proof verification. This drill reconstructs **operational** state only. It does not review the mathematics, and nothing here changes the node's classification, credit or flags.
+
+## Premise
+A cold agent is handed only the node id `math.d5-component.punctured-pin-proof`, with no chat history and no memory. LANES-20261022 names this node as Lane 1's expected `missing` example. Lane 2's `records/node_status/` does not exist on main yet, so the drill uses the records that do exist.
+
+## Steps (what was read, in order)
+
+| # | Read | Path / id | What it gives |
+|---|------|-----------|---------------|
+| 1 | Expected v0 record | `records/node_status/math.d5-component.punctured-pin-proof.json` | **Absent**: the directory does not exist at `f3b27d3c` (Lane 2 pending). Fall back to the static node page. |
+| 2 | Public node page | `docs/site/nodes/math.d5-component.punctured-pin-proof.html` @ `f3b27d3c` | "Resume this node" block, dated snapshot **as of 2026-10-13T14:56:55Z**. Graph: Math- `dbe6c0a1b1a22c7404b0fd173ee0043b98a08cde`, `frontiers/downstream_gate_20260925/GRAPH.json` (SHA-256 `8822e961…9dd09`). Main pin `b7deb198722582df191006e4f47238f92e6e543d`. Recorded classification `PROVED_REVIEWED`, controlling false, component of `math.d5-pin-neighborhood-first-moment`. Review basis: #111 (xAI, "ACCEPT algebra; continuum HOLD") and `d5_punctured_pin_continuum_claude_20260929` (Anthropic, "ACCEPT existential"). Next action, missing input, owner evidence and retained stop: **"not recorded in this snapshot"**. Graph-to-artifact binding: **unresolved**. Kernel, computation and alignment axes: not_recorded. |
+| 3 | Continuation pointer from the page | [main#327/6321244764](https://github.com/d6g8k5htny-coder/main/pull/327#issuecomment-6321244764) (dot, 2026-10-21T16:38:27Z) | The live operational request: a **SOURCE-ONLY binding** for this node, reusing `reviews/d5_local_collar_20260928/PUNCTURED_PIN_PROOF.md` (SHA256 `f972e50b…0f76a`, same as the graph fingerprint) and the crosswalk in `tests/fixtures/dependency_source_bindings.json`. Explicitly "not a duplicate claim, an accepted pickup, a writer activation or a lift of the pilot HOLD". |
+| 4 | Artifact Index bindings | `architecture/public-artifact-index-bindings.json` @ `f3b27d3c` | `[]`: **no bindings at all**. This is consistent with "binding unresolved". |
+| 5 | Crosswalk fixture exists? | `tests/fixtures/dependency_source_bindings.json` | Present in the tree at `f3b27d3c`. Contents not read in this drill. |
+| 6 | Lane context | [main#475/6346276856](https://github.com/d6g8k5htny-coder/main/issues/475#issuecomment-6346276856) | Lane 1 reports this node's projection as missing ("public projection not admitted (exporter repair #327, held by Claude017)"). #327 is on the untouched list. |
+
+## Reconstructed state (operational, not scientific)
+- **Owner:** none evidenced. The page records no owner, and 6321244764 is an invitation, not a PICKUP. Under v0, `owner` = `null`.
+- **Next action:** someone must personally accept the finite source-only binding input stage that 6321244764 asks for, or report the exact blocker.
+- **Missing input:** an authoritative ArtifactIndex row plus a typed node/artifact mapping, or a clearly new proposed registration submitted to the source authority.
+- **Stops:** the #327 exporter is HELD (Claude017), the pilot HOLD is not lifted, and no Ready/merge or scientific promotion is allowed.
+- **Freshness:** the node page snapshot is from 2026-10-13, more than 9 days old, so v0 status is `stale` or `unknown`, never `fresh`.
+
+## Gaps found
+1. No v0 record exists yet (Lane 2). The only operational state is a 9-day-old static snapshot whose four task fields are all "not recorded".
+2. `architecture/public-artifact-index-bindings.json` is `[]` at `f3b27d3c`. LANES Lane 1 says its first slice uses "an already-bound node from" that file, and none exists. **Lane 1 should be told.**
+3. `reviews/d5_local_collar_20260928/PUNCTURED_PIN_PROOF.md` is not in the main tree at `f3b27d3c`. It presumably lives in Math- at the graph pin. The drill did not verify this, so the source path is not resolvable from main alone.
+4. A cold agent cannot find out whether anyone has answered 6321244764 without reading the later #327 thread. That thread was not read here. The page itself warns that the comment is mutable and must be read live.
+
+## Next action for a resuming agent
+Read the main#327 thread after 6321244764 live. If no PICKUP answers it, report the node on #475 as: owner `null`, next action "accept source-only binding input stage (6321244764)", missing input as above, stops as above, status `stale`. Do not bind, register or promote anything; #327 is held.
