Snapshots, comparison, and reproducibility
Frozen scope, metric definitions, calculation references, owner watermarks, truth states, AI provenance, review state, content hash, and supersession.
Immutable report snapshots
Select a report or compare it to an explicit prior snapshot. Selection never changes the source report.

Frozen metric and calculation evidence
AI narrative remains separate and cannot alter these exact metric values.
| Metric | Value and truth | Kind | Definition hash | Calculation | Watermarks | Quality |

Explicit baseline comparison
Definition changes, no-value truth states, and incompatible scope remain non-comparable rather than producing false deltas.
| Metric | Current | Baseline | Truth states | Definition changed | Comparable | Delta |

AI narrative provenance and review
Typed insights and exact model provenance are separately attributable. No narrative can mutate frozen metrics.
| Insight | Status and kind | Metric and calculation refs | Evidence | Uncertainty and exclusions | Model route and revision | Policy |

Immutable and GET-only boundary
HTTP creation, correction, supersession, export, subscription, destination, approval, and dispatch are disabled. Offline creation uses deterministic content hashes and write-once storage. This workspace cannot rewrite a report, change a metric, execute an action, rank individuals, access protected Matter content, or access HammerTime Inbox material.
