+# PR #5133: backlog(B-0811): re-land of B-0741 (closed prematurely in stale-PR triage) — ontology+category negotiation; load-bearing for iter-7 (B-0806)
+
+## PR description
+
+## Summary
+
+Re-land of substrate originally filed as **B-0741** via [PR #5003](https://github.com/Lucent-Financial-Group/Zeta/pull/5003) on 2026-05-25. I closed it earlier in this session's stale-PR triage as Tier 3 (DIRTY-conflict); close-comment named the cherry-pick re-land path explicitly. This PR is that re-land.
+
+Renumbered to **B-0811** because B-0741 number remains taken on main (same pattern as #5132 renumbered peer Otto's classifier-bypass rows B-0800-0803 → B-0807-0810 today).
+
+## Substrate-inventory pass (per `.claude/rules/verify-existing-substrate-before-authoring.md` landed via #5131)
+
+Topic: `B-0741`, ontology negotiation, fork-negotiation, AI-skills+hats federation
+Searched surfaces:
+- `docs/agendas/` → ace-package-manager AGENDA includes hats + multi-oracle BFT
+- `docs/trajectories/` → ace-package-manager-skill-crystallization-pipeline
+- `docs/backlog/` → 10+ existing B-0741 cross-references; B-0742 sibling on hats-as-negotiated-fork-structure
+- `.claude/rules/` → non-coercion-invariant + tonal-momentum compose at related scope
+- `memory/` → ace + agora + agents-skills substrate
+- `docs/research/` → 3 files reference B-0741
+
+Conclusion: substrate is REFERENCED (not just orphan); re-land closes dangling cross-refs.
+
+Authoring action: cherry-pick + renumber + add re-land-context section.
+
+## Why this matters now
+
+Per the maintainer 2026-05-26 catch on iter-7 (B-0806): *"i'm assuming you have the hat / fork negoation for ace too"*. Cross-fork ontology negotiation is the third layer of every `ace install <pkg>` action per B-0806's architectural integration section. B-0811 (= the original B-0741) substrate is load-bearing for that.
+
+## Test plan
+
+- [x] Content is verbatim from PR #5003 commit `0f691dbec` (only `id:` + filename + re-land-context section differ)
+- [x] All original composes_with targets (B-0247/B-0287/B-0288/B-0731/B-0727/B-0726/B-0638/B-0703) still exist on main — cross-refs preserved
+- [x] BACKLOG.md regenerated
+- [x] B-0535 ID-uniqueness lint (now clean post-#5132) — B-0811 is unique

+
+P1: `last_updated` is required to be updated on every content edit; since this row adds new “Re-land context” content in this PR, `last_updated` should reflect the re-land/edit date (likely 2026-05-26) rather than staying at 2026-05-25.
