Summary

Applies a /simplify review of docs/superpowers/specs/2026-08-02-crewboss-platform-design.md (4 parallel review angles: reuse, simplification, reader efficiency, altitude). Every change preserves the spec's normative meaning — this pass removes duplicated rules that had already begun to drift, dead review-round prose, and implementation detail below the doc's contract altitude.

Changes

Duplicated normative rules, now stated once with references:

• Sandbox denial set was enumerated in five places (15.7, 19.5, 21.2, 21.5, 31.8) with already-diverged lists; 21.2 is now the canonical denial set and the other four sites reference it.
• Cutover barrier/spool/recovery was fully described in both 14.4 and 25.4; 25.4 now owns it, 14.4 keeps only worker-visible behavior. The emit special case is reformulated into a general rule (worker-evidence mutations are never dropped).
• Grant consumption/revocation semantics consolidated into 21.6 (was also in 12.1 and 13.6).
• return_state valid pairs defer to the section 13 state machines instead of being re-listed in the schema; the "never infer from…" enumeration collapsed to the deeper rule.
• Provider-credential exclusion lists (12.1 vs 21.2) merged into one union in 21.2.
• 15.7's per-route release schedule removed in favor of section 26's public surfaces; authority notes added so section 3 defers to the 27 matrix and 27 defers to 26.
• Actionable severities defined once in 14.3; 15.5's prose error-code list that duplicated its own table removed.

Dead prose and altitude:

• Removed three leftover review-round rebuttal sentences and bare restatements of the terminal-text and zero-idle-cost principles.
• Section 4 baseline now cites the phase-1 event-log spec as authoritative; config example labeled illustrative; UUID pre-generation mechanics replaced with the atomicity invariant; frozen-Bash-code rationale dropped from the worktree adapter.

Reader efficiency:

• 25.2 import invariants and 25.4 crash-recovery rules converted from mega-paragraphs to bulleted invariant lists (same sentences).
• Vocabulary table gains Endpoint, Consumer, Approval, and Grant rows plus the "boss" alias.

Not changed (intentionally)

• The 17.2 "fair sharing" tie-break remains unspecified — naming a deterministic rule is a design decision, flagged for a future design update.
• No TOC added (GitHub renders a heading outline automatically) and no egress column added to the 21.2 profile table (would re-duplicate the prose egress rules).
