Adds rig context reconstruction inspect|view <revision>, which reads exact immutable v0 base records, replays deltas and follows pinned compositions from local stores, with no daemon call, skill install, context projection or remote fetch. The catalog project and work home are resolved through catalog-selection logic extracted from work-install, so both use the same selection. Inspect shows source manifests, purpose, depth, dates and approximate size; view keeps constraints, authority, gaps and transitive dependencies, shows actual omissions apart from authored coverage, and keeps inherited observation dates. A missing record or reference stays an explicit incomplete result. A store that exists on this machine is read at its original path; a store that moved needs a read-time mapping, and immutable pointers and revision IDs are never rewritten. Canonical hashes are Python-compatible for safe integer JSON values, and unsupported numeric representations are rejected. Every byte read is charged against a 32 MiB budget before it is decoded or parsed, and later reads stop once it is spent. docs: reconstructions.md and project-workspace.md describe the commands.
