Generate reviewable evidence inventories instead of hardcoded counts

[woksin]

Problem

Several high-value V4 evidence gates intentionally fail closed on fixed counts: Storybook expects 64 story modules, 261 stories and 64 autodocs pages per renderer, while the package graph records 34 kernel modules. The counts caught drift during V4, but a legitimate addition requires editing verifier constants by hand and can make a stale number look like architectural policy.

Direction

Generate evidence inventories from authoritative inputs while retaining reviewable golden snapshots:

• Storybook inventory from built indexes plus source story modules;
• renderer set from validated adapter metadata;
• kernel inventory from the declared kernel-boundary source;
• parts/state counts from the generated parts manifest;
• package subpaths from the export map.

CI should compare generated inventory bytes with a committed, reviewable snapshot. A change must fail until the snapshot and rationale are reviewed, but verifier source should not need an unrelated constant edit.

Acceptance criteria

• No story, autodocs, renderer, kernel, parts/state, or export count is duplicated as an unexplained verifier constant.
• Generated inventory is deterministic and checked into source or uploaded with an exact base/head diff.
• Removing a story/renderer/kernel entry fails and names the missing identity, not only a count.
• Legitimate additions require an explicit reviewed inventory update.
• No sampling or silent truncation is introduced.
