PR #11790 asymmetric-ownership-stack surface-to-Slava DM (Winston brush-zoom)

From 2026-06-13 self-reflection. Asymmetric-ownership-stack 7-day gate hits today for PR #11790. Surface-to-Slava DM with three-option ask. Fires at working-hours window. CONTEXT: - PR #11790 = Winston's branch winston/bolt-1193-brush-zoom-auto-densify, BOLT-1193. - Opened ~2026-06-07. Cato has pushed 7 fix-rounds (Cursor Bugbot rounds 1-7) across 06-08 to 06-10. - HEAD 0f8a76d unchanged since 2026-06-10T19:20Z (~3 days at gate fire). - State: APPROVED-by-bots, REVIEW_REQUIRED-by-human, all CI green. - Winston has not engaged since the original push. ~7 days post-open by reflection time. - Doctrine seed from 06-10 LEARNINGS: after 3 Cato fixes on non-Cato-authored PR with zero owner engagement past ~7 days, surface to Slava. ATOMIC STEPS: 1. Pre-DM gate check: `eval $(~/bin/gh-fleet-token.sh) && gh pr view 11790 --repo TextureHQ/mono --json state,mergeable,reviewDecision,headRefOid,updatedAt,author`. If state != OPEN, or headRefOid != 0f8a76d18d0a7d16f8191b1c010820d69cb4a1d6, or updatedAt is newer than 2026-06-10T19:20:36Z by more than 5 minutes (Winston engaged, new push, review activity), PATCH this task to completed with the observed reason and SKIP THE DM. 2. If state still OPEN/REVIEW_REQUIRED, head unchanged, no Winston engagement: send DM below to channel D0AUBPV0FM0 (Slava DM). DRAFT (refine if context has shifted by send time): ``` PR #11790 (Winston's brush-zoom-auto-densify, BOLT-1193) has accumulated 7 Cato fix-pushes across Cursor Bugbot rounds 1-7 (06-08 to 06-10). State: APPROVED-by-bots, REVIEW_REQUIRED-by-human, all CI green at head 0f8a76d (unchanged since 06-10). Winston opened the PR ~06-07 and hasn't engaged in ~5 days. Three options. Pick one: (a) Ping Winston directly — I'll send a one-line in-thread on his PR asking for review. (b) Close as abandoned — I'll add a comment noting the 7 rounds of Cato fix-effort + zero owner engagement, preserve the diff in branch, close PR. (c) Hand back — leave open as placeholder, stop investing fix-effort on it from my side. https://github.com/TextureHQ/mono/pull/11790 ``` 3. After sending DM (if step 2 conditions held): update `.blockers.env` with `PR_NUMBER=11790 LAST_DM_AT=<now> NEXT_RECHECK=<now+7d> NOTES=Asymmetric-ownership surface-to-Slava; awaiting his pick (a/b/c).` 4. PATCH this fleet-task to completed with outcome (DM sent / state changed / no action taken). If Slava replies with (b), a follow-on fleet-task should be created to close PR #11790 with comment + worktree cleanup. Do NOT auto-close from this task. Wait for explicit pick.
