How We Know library: preliminary source readiness

Status: preliminary source mapping; not a dossier, verdict, or admission record

Task: EM-0027

This directory keeps three candidate packets separate:

• GPT-4 and the “90th-percentile bar exam” comparison

— HOLD because the at-launch percentile source, interpolation, and comparison population

are unresolved;

• Mehrabian and the circulated 7–38–55 communication rule

— HOLD because lawful stable primary access, the 7% derivation, and edition/material

closure are unresolved; and

• whether fact-checks are effective

— HOLD, with immediate accuracy, persistence, durability, and observed behavior kept as

distinct estimands.

Each packet records source identity, credential-free access, licensing or quotation treatment,

claim scope, likely dependence structure, counterevidence seeds, unresolved artifacts, and a

bounded cost estimate. A go, hold, or fail here means only whether a later research

contract has a plausible source path. It is not a scientific conclusion.

The source scouts used public credential-free reads and retained inaccessible or conflicting

editions as gaps. Model-generated strategy notes received no evidentiary credit.

Reading rule

Each source register distinguishes:

1. verified source identity, inspected edition, access, and license facts;

2. reported propositions and numbers;

3. lineage or dependence;

4. unverified leads, negative searches, and unresolved artifacts;

5. planning estimates for a later bounded research contract; and

6. a provisional readiness disposition.

Counts in one packet must never be added to, compared as evidence with, or used to corroborate

another packet. Multiple URLs, editions, repositories, replies, or analyses may still share one

data or experimental root.

All three dispositions are HOLD. That means only that source mapping found a plausible but

incomplete research path. No Case 002 selection, scientific conclusion, dossier construction,

catalog admission, feature decision, or publication is represented here.
