Shay 80aa971db3 docs(adr): ADR-0021 Epistemic Grade Policy — coherence is the only signal
Establishes a typed epistemic surface for stored claims without
importing any source-trust bias. The status enum (COHERENT,
CONTESTED, SPECULATIVE, FALSIFIED) describes a claim's position
in the revision graph, not the credentials of its source. No
tier in the schema carries inherent trust weight.

Three commitments:
1. epistemic_status is a position in the revision graph, not a
   trust tier. Source labels (peer_consensus / outsider /
   established / unauthoritative) are explicitly excluded.
2. Non-hardening invariant: no reviewed claim, relation, or
   edge ever becomes unrevisable. No final/frozen/axiom flag
   may be added. Stage-3 inversion (versor-conjugate
   correction) is always available.
3. Coherence is the only admission signal. v1 is curator-
   mediated but bias-free at the schema level; v2 must add a
   structural coherence metric so the tag has geometric teeth
   and not just curator authority.

Schema impact: PackMutationProposal.epistemic_status,
review outcome carries status alongside ACCEPTED/REJECTED_IDENTITY,
lexicon entries get an optional epistemic_status field,
trace_hash folds in epistemic_status for replay verification.

Named v2 gap: structural coherence metric recipe (cga_inner
agreement with the existing reviewed field) is committed as
the path forward.

Implementation lands as a Phase 5 parallel-track item alongside
Rust parity per ADR-0020.

Architecture Decision Records

This directory contains the Architecture Decision Records (ADRs) for the CORE project.

ADRs record significant architectural decisions: what was decided, why, what alternatives were considered, and what consequences follow. They are permanent records — superseded ADRs are archived, not deleted.

Session Logs

Session logs record the decisions and rationale from individual working sessions. They are not ADRs — they are the narrative record that informed the ADRs.
