# Retained Evidence Drill 0.1

Status: source-only experimental profile.

Profile: `glyph.retained-evidence-drill/0.1-experimental`.

Report: `glyph.retained-evidence-drill-report/0.1-experimental`.

Judgment: `glyph.retained-evidence-judgment/1`.

This drill asks whether retained artifacts remain sufficient to reproduce a
historical report, establish a later same-size witness conflict without
inventing correction authority, and then recompute declared reliance after an
accepted correction notice is supplied.

The three states reuse frozen Bulla source-only fixtures and dependency-free
Node verifiers without changing them:

- `published`: the accepted checkpoint history is consistent.
- `fault-observed`: authentic same-size witness heads establish equivocation;
  no correction notice or Reliance Map conclusion is present.
- `corrected`: the accepted correction notice authorizes a graph-relative
  recomputation over the frozen 10,000-decision declaration.

The transaction record is byte-identical across all three states. The drill
constructs a closed judgment from consequence-bearing verified fields, hashes
that judgment, and derives each delta by comparing the canonical objects.

## Review-all control

Without accepted lineage sufficient to separate a declared decision from the
disputed source, the control treats every declared decision as requiring
review.

In this fixture, declared lineage reduces the review set from 10,000 to 5,000
without clearing incomplete ancestry. The exemption is by accepted
declaration, not proof of organizational or causal independence.

## Jurisdiction

The packet establishes local reproduction from packet members under the
supplied verifier and receiver contexts. The launcher blocks and counts calls
through enumerated Node network interfaces; it does not establish
operating-system network isolation. Repository input and prior receiver state
are not supplied, installed Bulla is not used, and no Glyph Standard route is
requested. The result does not establish freshness, current revocation or
external state, independent operation, occurrence, worldly truth, custody,
settlement, or causal independence. Running it does not increment an external
counter.
