docs/planning/v4-branch-e-self-host-bootstrap-dag-regen-rr-e-worksheet-2026-06-02.mdThe worksheet keeps canonical .dag source as the single authority, rejects JSON IR/emitted Rust as regen substitutes, and gates Branch E on H/C receipts.
ROADMAP — Verified
- Self-host fixed point: The design preserves the pure-bootstrap fixed-point path by making source round-trip and bootstrap receipts prerequisites before hand-maintained Rust dissolution.
✅ No blocking concerns.

…re-emit acceptance shape) (#4368) W4-prep design only. Names the bit-identical re-emit fixed-point acceptance shape over the existing v4 four-stage bootstrap.dag plan and the declared self_host.dag witness types (FixedPointEqual + BootstrapRoundtripEqual -> PromotionWitness). No model redeclaration, no runner realization, no stage0 Rust dissolution. Enumerates the W4.7 gate chain (Rung 1 #4353 hard blocker, T-15 B1 content_hash, candidate generation) and the forbidden gaming shapes (placeholder-digest fixed point, stage0 Rust cementing, JSON-IR round-trip). Follow-on to RR-E (#4288) and E.3 DAG-regen closure (#4302). Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Summary
Adds the W2 RR-E Branch E worksheet for self-host, bootstrap-as-data, and DAG-source regeneration design. The PR is design-only: it does not add bootstrap substrate rows, TestClaim rows, a self-host implementation, a DAG regeneration executor, or any Rust-to-DAG decompilation path.
The worksheet records the E.3 crux: current
gunbc compile --target dagoutput is not canonical.dagsource. Branch E depends on Branch H's H.1 source-AST canonical serializer and consumes Branch C C.1-C.5 only as a downstream Shape-A scaling dependency after C.5 is green.Review feedback addressed
DagRegenDesignOnly { sentinel: Symbol }substrate surface and the associated manual claim/test ratchet. The effective PR diff is now only the Class 1 worksheet, so the Symbol-sentinel modeling violation reported on the earlier commit is gone.Test plan
git diff --check— passed.Coordination
swift-lark-66) confirmed serializer wording: canonical.dagserialization is over H.1 source AST and round-trips by normalized H.1 AST equality.silent-bear-54) confirmed C/D dependency wording: Branch E consumes C.5 green for Shape-A scaling, does not co-own06_translate, does not expand05_emit, and keeps RR-D Shape-B guarded/orthogonal.Work item:
