1.8.0

Added

• design-fidelity now degrades gracefully when its sibling skills are absent or untriggered, running the build as an ordinary craft task with the repo's named check inline; it never hard-depends on mission-control or test-discipline.

Changed

• The fanout guard now arms on frontier sessions generally (Fable 5 and Opus), not Fable 5 alone: an unpinned Agent call or any Workflow on Opus is held to the same explicit-model and approval-token rules. The hook filename is unchanged for install compatibility.
• The routing grid resolves the equal-tier case: equal-tier delegation is explicitly allowed (same token rate, fresh context and parallelism), while up-delegation to a model above the session requires the user's explicit approval. The ceiling rule now reads "at or below, never above".
• VERIFY now re-runs the named check for a code lot instead of trusting the executing agent's quoted output.
• Parallel-lot isolation now covers shared mutable state (the git index, lockfiles and installs, dev ports, test databases), not only shared files.
• The Workflow deny message now states the two real options (fall back to pinned parallel Agent calls, or pass the approval token) instead of the dead-end suggestion to pin the script.

Fixed

• A duplicated frontier-subagent-prompting section in mission-control's SKILL.md collapsed into a pointer. The file still runs over the ~200-line adherence target since this release's added doctrine outweighs the trim; a further slim is queued.
• Smaller coherence fixes: the inline-execution exception generalized beyond one-line edits, typography tolerance defined for pixel-only references, the up-delegation cutoff rephrased to an observable stop condition, and the guard's first-turn fail-open documented honestly in HOOKS.md.
