docs(evaluator): audit E8 runner continuation

[briansrls]

Summary

• adds a docs-only PR-E E8 runner-extension continuation readiness audit
• records that AlgebraicLaw::Commutativity is already wired while Identity and Distributivity remain substrate-gated
• records that W1/W3 executable runner work is still blocked on declared producer identity / observation-channel authority despite ProgramObservation existing
• links the readiness note from the R3 evaluator dispatch brief

Verification

• git diff --cached --check
• pre-push hook: cargo fmt --all --check

Scope

Docs-only. No test_runner.rs changes, no new TestPredicate variants, no substrate changes, no ForAllTargets execution, and no stdout/Bool-as-Disj bridge.

[briansrls]

Manager pass: scope is correct for the E8 continuation dispatch. This is docs-only, keeps untouched, recognizes as landed, and correctly holds W1/W3 execution behind producer identity / observation-channel authority instead of adding name-keyed runner dispatch or stdout conventions.\n\nNo manager-blocking changes requested. Hold for CI / scheduled reviews.\n\n— sent from snappy-moth-795

Correction to the prior manager-pass comment: shell command substitution stripped the inline code spans. Intended disposition:

Verdict

APPROVE — The diff is documentation-only: a continuation-readiness audit for E8 plus a short pointer from r3-evaluator-dispatch.md. It reinforces fail-closed and single-authority framing (explicit non-goals, no new TestPredicate variants, no test_runner.rs expansion without contracts), and spot-checks against the tree show the cited wiring (Associativity/Commutativity and cost-only DifferentialEquals pairing in test_runner.rs, AlgebraicLawKind without Distributivity in verification.dag, ProgramObservation in runtime.dag) match the described live state. Nothing in the diff violates INVARIANTS.md, modeling-discipline.md, CODING.md, or TESTING.md in a material way.

Exploratory observations (optional)

• The new blurb in r3-evaluator-dispatch.md (around the added lines) calls out only AlgebraicLaw::Commutativity as wired; the linked audit states both Associativity and Commutativity are wired. That is not false, but the one-line summary is easy to read as exclusive—harmless if readers follow the link.

Findings: None.

Non-blocking — Strengths

• docs/briefs/r3-pr-e8-runner-extensions-continuation-readiness.md Docs-only change: the audit keeps E8 runner work fenced behind declared producer identity and observation-channel authority instead of widening runner-local authority.

✅ No blocking concerns for this docs/readiness audit.

APPROVE — Docs-only readiness audit. The new brief is bounded, fail-closed in tone, names dissolution triggers per workstream, and the parent brief link in r3-evaluator-dispatch.md:169-174 is a clean cross-reference. No code, substrate, or test changes; nothing in the diff conflicts with INVARIANTS, MODELING, CODING, or TESTING.

Verdict: APPROVE

Diff is docs-only, narrowly scoped, and consistent with the pinned invariants: it keeps E8 executable work blocked where producer identity, observation authority, and substrate edges are missing, while recording the already-wired Associativity / Commutativity state. No concrete violations observed.

I did not run builds or tests, per review instructions.
