+description: "Amara cascade continuation 2026-05-21 — 4 sandbox docs confirmed ready + trust-gradient consensus decision-table drafted as 5th deliverable. Aaron's substantive refinement: row-level CASPaxos/CASRaft tier between optimistic CAS and BFT prevents jumping from local-CAS-too-weak to BFT-too-heavy. Amara's deeper reframe: 'trust-gradient COORDINATION POLICY, not consensus hierarchy' — because some tiers (local DBSP retraction = algebra; Orleans grain ordering = actor lifecycle) aren't consensus at all. Routing-gradient-not-mandatory-staircase: pick the weakest mechanism that preserves the needed authority boundary; facts can jump tiers. Final 6-line keeper: 'Local facts stay retractable / Runtime facts stay ordered by their owner / Contended rows coordinate narrowly / Long workflows compensate / Cross-boundary facts negotiate capability / Adversarial commitments use BFT.' Direct extension of PR #4546 trust-gradient framing."

+# Amara — trust-gradient coordination policy + row-level CASPaxos/CASRaft tier + 4 sandbox docs confirmed ready
+
+**Date**: 2026-05-21
+**Surface**: Amara on ChatGPT/Aurora (external AI; deep-research/sharpen register)
+**Provenance**: Aaron-forwarded preservation per `.claude/rules/substrate-or-it-didnt-happen.md` verbatim-preservation trigger
+**Companion archives** (all on main):
+- PR #4545 — B-0685 Phase 1 + ZetaParse + incremental compiler host scaffolding + B-0687/B-0688 backlog rows
+- PR #4546 — Caché-lineage + distributed multidimensional compiler over consensus + IUnknown-without-DCOM
+- PR #4547 — no-fork-first deployment ladder + fork-as-reward-not-entrance-fee
+
+**Composes with**: PR #4546 trust-gradient framing (extended with row-level CASPaxos/CASRaft + COORDINATION POLICY reframe), B-0688 (incremental compiler host — gradient applies to compiler-fact consensus decisions)
+
+## Why this is preserved (fourth Amara archive for 2026-05-21)
+
+This cascade lands two substantive deliverables:
+
+1. **Confirmation that 4 sandbox design notes are ready for Aaron-forward** (the 4 docs referenced from PR #4545 + PR #4547)
+2. **Trust-gradient consensus decision table — 5th sandbox doc** — drafted as standalone reference, then refined twice through Aaron-Amara exchange to land as: **trust-gradient COORDINATION POLICY** (not "consensus hierarchy") with 6 tiers including the row-level CASPaxos/CASRaft intermediate tier between optimistic CAS and BFT
+
+The trust-gradient substrate is the canonical "where does consensus apply?" reference for future Zeta substrate decisions — and the refinement-arc preserves the substrate-engineering pattern of "pick weakest mechanism that preserves the needed authority boundary."
+
+## Amara's confirmation — 5 sandbox docs ready for Aaron-forward
+
+> *"Yes. I closed the dangling artifact chain and also drafted the trust-gradient consensus table. Here are the files Otto needs:"*

+
+> *"And here's the full bundle: [Download all Amara design notes as a ZIP](sandbox:/mnt/data/amara-design-notes-2026-05-21-bundle.zip)"*
+
+**STILL PENDING**: Otto cannot access `sandbox:/mnt/data/*` URLs directly — they live in Amara's ChatGPT/Aurora sandbox, not in Zeta's repo or any URL Otto can fetch. **Aaron needs to PASTE THE TEXT CONTENT** (not the link) of each file into chat for Otto to commit. The link is unreachable from Otto's surface.
+
+The substantive content of the trust-gradient decision table IS in this archive (preserved from the forwarded conversation below). The other 4 sandbox docs' full content is still pending Aaron-forward of text body.
+
+## Trust-gradient decision table v1 (first draft, Amara)
+
+> *"The consensus table's keeper line is: 'Local facts stay retractable. Shared authority escalates. BFT is for adversarial commitment, not for breathing.'"*
+
+> *"That should slot cleanly after PR #4546/#4547 as the canonical 'where does consensus apply?' reference."*
+
+## V2 — Aaron-correction adds row-level CASPaxos/CASRaft tier
+
+Aaron's correction (verbatim):
+
+> *"That's the right refinement. I updated the consensus table to add row-level CASPaxos/CASRaft before BFT."*
+
+Amara's v2 gradient:
+
+```text
+no consensus
+→ local sequential order
+→ optimistic row-level CAS
+→ row-scoped replicated CASPaxos/CASRaft
+→ saga compensation
+→ negotiated cross-boundary causality
+→ BFT multi-oracle commitment
+```
+
+### Why the row-level tier matters (Amara's framing)
+
+> *"That intermediate tier is important because a contended row is usually coordination pressure, not adversarial truth. So BFT would be overkill."*
+
+### Operational unit Amara proposed
+
+```text
+QueryStateRow {
+  queryId
+  partitionKey
+  rowKey
+  version / clock
+  bonsaiExpressionHash
+  zsetWeight
+  payloadHash
+  provenance
+}
+```
+
+### Operation shape
+
+```text
+old row state
++ serialized Rx/Bonsai query update function
++ expected version/clock
+    -> new row state
+```
+
+### V2 keeper line
+
+> *"Local facts stay retractable. Contended rows coordinate narrowly. Shared authority escalates. BFT is for adversarial commitment, not for breathing."*
+
+## Final refinement — TRUST-GRADIENT COORDINATION POLICY (not consensus hierarchy)
+
+Amara's final reframe + 6-line keeper:
+
+> *"It seems good to me. Not too restrictive as long as we treat it as a routing gradient, not a mandatory staircase."*
+
+### The discipline
+
+> *"Pick the weakest mechanism that preserves the needed authority boundary."*
+
+> *"So a fact does NOT need to climb every tier. It can jump directly to the right mechanism."*
+
+### Jump-table example (Amara)
+
+```text
+local AST tag
+→ stays local
+
+same-grain operator update
+→ Orleans ordering
+
+contended row
+→ row-level CAS / CASPaxos / CASRaft
+
+long-running workflow
+→ saga / durable task
+
+cross-trust interface
+→ capability + identity + policy negotiation
+
+adversarial shared truth
+→ BFT multi-oracle
+```
+
+### The conceptual rename Amara surfaced
+
+> *"The only edit I'd make conceptually: Do NOT call it a consensus hierarchy. Call it a trust-gradient coordination policy. Because some tiers are not consensus at all:"*
+
+```text
+local DBSP retraction = algebra
+Orleans grain ordering = actor/runtime lifecycle
+row CAS = optimistic coordination
+CASPaxos/CASRaft = row-scoped consensus
+Saga = compensation protocol
+BFT = adversarial agreement
+```
+
+> *"That's good. It keeps each mechanism in its proper place."*
+
+### Final 6-line keeper (the canonical reference)
+
+> *"My final keeper version:"*
+
+```text
+Local facts stay retractable.
+Runtime facts stay ordered by their owner.
+Contended rows coordinate narrowly.
+Long workflows compensate.
+Cross-boundary facts negotiate capability.
+Adversarial commitments use BFT.
+```
+
+> *"That is not restrictive. That is exactly the kind of gradient that keeps Zeta from becoming either under-governed chaos or consensus-everywhere sludge."*
+
+## Operational implications for Zeta substrate
+
+### For B-0688 incremental compiler host
+
+The trust-gradient coordination policy applies directly to compiler-fact consensus decisions:
+
+- Local AST tags / parser output / generator output stay retractable (DBSP algebra)
+- Same-grain operator updates use Orleans ordering (actor lifecycle)
+- Contended compiler-DB rows (e.g., type-symbol contention across concurrent generator runs) use row-level CAS / CASPaxos / CASRaft
+- Long-running build workflows use saga compensation (Durable Tasks)
+- Cross-trust compiler-DB federation uses capability negotiation
+- Multi-oracle adversarial agreement (e.g., signed code-artifact provenance) uses BFT
+
+The gradient becomes operational at compiler-fact-emission scope.
+
+### For B-0635 / B-0644 / B-0665 / B-0666 (Agora V6)
+
+The trust-gradient coordination policy IS Agora V6's Integrate-as-choice-locus discipline at distributed-systems scope:
+
+- Choice-locus per Integrate = "which coordination tier does this fact require?"
+- Limit-as-simulation per B-0644 = "simulate the consensus before committing to a tier" (compose with seeded-deterministic discipline per B-0688)
+- Wave-particle-duality per B-0635 = "tier-deferred causality" (B-0683) = facts can be in superposition of coordination tiers until forced to collapse via Integrate
+
+The Agora V6 operational primitives compose at distributed-coordination scope.
+
+### For the existing CRDT substrate (`src/Core/Crdt/*`)
+
+The CRDT substrate IS the algebra tier (no consensus). The trust-gradient coordination policy gives the architectural framing for when CRDTs are sufficient vs when escalation is needed:
+
+- Pure CRDT operations → algebra tier (no consensus)
+- CRDT operations that need authoritative current state → row-level CAS at the read boundary
+- CRDT operations across trust boundaries → capability negotiation (sets the conditions under which CRDT merges are accepted)
+- Multi-oracle adversarial CRDT state (e.g., contested invariants) → BFT
+
+## Composes with rules
+
+- `.claude/rules/substrate-or-it-didnt-happen.md` — verbatim-preservation trigger; 4th Amara archive for 2026-05-21
+- `.claude/rules/agent-roster-reference-card.md` — Amara's external-AI register operating
+- `.claude/rules/m-acc-multi-oracle-end-user-moral-invariants.md` — multi-oracle by design; the trust-gradient coordination policy IS the architectural pattern that prevents single-consensus-truth imposition; each tier serves a different authority boundary
+- `.claude/rules/dv2-data-split-discipline-activated.md` — coordination policy IS DV2.0 partition-by-authority-rate; different change-rate dimensions get different coordination mechanisms
+- `.claude/rules/bandwidth-served-falsifier.md` — weakest-mechanism discipline serves the deployment-velocity bandwidth (don't pay consensus cost where authority boundary doesn't require it)
+- `.claude/rules/razor-discipline.md` — the rename from "consensus hierarchy" to "coordination policy" IS razor-discipline at framing scope (algebra ≠ consensus; ordering ≠ consensus; the imprecise framing collapses real distinctions)
+- `.claude/rules/all-complexity-is-accidental-in-greenfield.md` — BFT-everywhere is accidental complexity; the trust-gradient names which accidental-complexity tiers stay accidental until proven essential
+- `.claude/rules/edge-defining-work-not-speculation.md` — coordination policy IS edge-defining work; gives a citable reference architecture for distributed-coordination decisions
+
+## Composes with substrate
+
+- PR #4546 (Caché-lineage + distributed multidimensional compiler + IUnknown-without-DCOM) — the trust-gradient framing this cascade refines
+- PR #4545 (B-0685 Phase 1 + B-0687 + B-0688) — backlog scaffolding the trust-gradient applies to
+- PR #4547 (no-fork-first deployment ladder) — the no-fork-first stack uses the trust-gradient at every layer
+- B-0635 / B-0644 / B-0665 / B-0666 (Agora V6 substrate) — trust-gradient IS Integrate-as-choice-locus at distributed-systems scope
+- B-0683 (tier-deferred causality) — facts can be in superposition of coordination tiers
+- B-0687 (ZetaParse) — parser substrate stays at algebra tier (local DBSP retraction)
+- B-0688 (incremental compiler host) — full trust-gradient operates at compiler-fact-emission scope
+- `src/Core/Crdt/*` (existing CRDT substrate) — algebra tier; trust-gradient gives the framing for when escalation is needed
+- `src/Core/Consensus.fs` (existing consensus substrate; if exists) — CASPaxos/CASRaft tier substrate
+- Earlier Amara persona substrate cluster + Kestrel persona substrate cluster
+
+## Substrate-honest framing
+
+The trust-gradient COORDINATION POLICY is operationally load-bearing for Zeta's distributed-compiler vision. The refinement-arc preserves the substrate-engineering pattern: v1 → Aaron correction (add row-level tier) → Amara reframe (it's not consensus, it's coordination) → final 6-line keeper. Each iteration sharpens the framing without losing the substrate.
+
+The 4 sandbox docs from the earlier cascade + the 5th (trust-gradient) are ready for Aaron to forward text content. The persona archives (this PR + PR #4545 + PR #4546 + PR #4547) cover the SUBSTANTIVE content of all Amara's substrate-engineering work; the sandbox docs would land the formal artifacts the persona archives reference.
+
+If Aaron pastes the sandbox doc text content, Otto commits each to its target path in a follow-up PR. The persona archives establish the scaffolding; the sandbox docs land the formal deliverables.
+
+## Full reasoning
+
+Aaron's full forwarded conversation captured above. The 4-archive cluster (PR #4545 + PR #4546 + PR #4547 + this PR) covers Amara's substantive 2026-05-21 substrate cascade. The 5 sandbox docs (4 from earlier + 1 trust-gradient) are pending Aaron-forward of full text content (not links — `sandbox:/mnt/data/*` URLs are unreachable from Otto's surface).
