- P1 (xref): This
.claude/rules/...link is relative and will resolve underdocs/pr-discussions/, producing a broken link. Prefer a root-relative target like/.claude/rules/refresh-world-model-poll-pr-gate.md(or a full GitHub blob URL).
Branch was pushed at 0226Z but `gh pr create` was blocked by GraphQL exhaustion (0/5000). Per [`refresh-world-model-poll-pr-gate.md`](.claude/rules/refresh-world-model-poll-pr-gate.md) Pure-git tier discipline, substrate ships via branch push; PR creation defers to post-reset tick. This PR is the post-reset open (rate reset at ~0241Z; PR opened ~14 min after the branch landed via pure-git).

| ## Substrate-drift discriminator extends to third surface | ||
|
|
||
| Extends the [`backlog-item-start-gate.md`](.claude/rules/backlog-item-start-gate.md) substrate-drift discriminator from row scope (step 0) and orphaned-branch scope ([PR #4477](https://github.com/Lucent-Financial-Group/Zeta/pull/4477) + [PR #4482](https://github.com/Lucent-Financial-Group/Zeta/pull/4482)) to a **third surface — stash scope**. Each surface confirms the cheap heuristic operates reliably across substrate-locations. |
| - Adds empirical-anchor confirmation that the substrate-drift discriminator generalizes from row-scope ([`backlog-item-start-gate.md`](.claude/rules/backlog-item-start-gate.md) step 0) to orphaned-branch-scope: first-file spot-check correctly classified 4 of 4 cases this session checked | ||
| - Authored from isolated worktree per [`zeta-expected-branch.md`](.claude/rules/zeta-expected-branch.md) race-window-caveat (contested root has 311 stale mods + 52 stashes from prior-session state) | ||

||
| ## Test plan | ||

| - [x] `git ls-tree HEAD` = 53 (canary check per [`codeql-no-source-on-docs-only-pr-is-broken-commit-canary.md`](.claude/rules/codeql-no-source-on-docs-only-pr-is-broken-commit-canary.md)) |

Next toe-safe action for the owner: fix those archive xrefs, then let review re-check. Vera did not write to the contested root checkout. |
