docs: correct READINESS.md grade C → X (honest assessment)

Template default of C was aspirational. Per CRG v2.0 STRICT:
"honest D > dishonest B". Repo is scaffolded but has no KRL-specific
content beyond template placeholders — honest grade is X.

Path to E documented: grammar draft + 1 smoke test.

-## Summary
+## Grade rationale (evidence for X)
 
-| Component           | Grade | Release Stage | Evidence Summary                          |
-|---------------------|-------|---------------|-------------------------------------------|
-| Primary component   | C     | Alpha-stable  | Dogfooded on own project; CI passing      |
+**Untested — default state.** Repository was scaffolded from rsr-template-repo
+on 2026-04-05. No KRL-specific content beyond the template placeholders exists yet.
 
-**Overall:** Grade C — dogfooding confirmed, CI passing, deep annotation in place.
+Template default of "C" was overridden to X per CRG v2 STRICT honesty rule:
+"Grade as-is TODAY, not aspirational — honest D > dishonest B".

+### What exists
+
+- RSR template infrastructure (workflows, SECURITY/CONTRIBUTING/CODE_OF_CONDUCT, `.machine_readable/6a2/` skeleton)
+- 0-AI-MANIFEST.a2ml
+- Template-provided directory structure
 
-## Grade C Evidence
+### What does not yet exist
 
-- Deployed and dogfooded on the krl project itself
-- CI passing (dogfood-gate, hypatia-scan, static-analysis-gate)
-- TEST-NEEDS.md documents test matrix
-- No home failures
-- Deep code and folder annotation in place per CRG v2 requirements
+- KRL grammar (EBNF/PEG)
+- Parser, AST, typechecker, compiler
+- Surface-syntax examples
+- KRL-specific test suite
+- Language reference documentation

-## Promotion Path to Grade B
+## Path to E (pre-alpha)
+
+1. Draft KRL EBNF/PEG grammar with `construct`, `transform`, `resolve`, `retrieve`
+   operation families + compositional syntax (`;`, `|`, `close`, `let`, `find`).
+2. Add at least 1 test — smoke test that parses a "hello tangle" KRL source.
+3. Document known failures / incomplete grammar branches.
+
+## Path to D (alpha)
+
+After E: AST + typechecker + rudimentary compiler to TangleIR (via KRLAdapter.jl)
++ test matrix across parse/typecheck/compile stages.
+
+## Path to C (alpha-stable)
 
-Grade B requires: **6+ diverse external targets tested, issues fed back**.
+After D: deep annotation, per-directory orientation, reliable dogfooding
+(compile several real KRL programs into stored Skein records).
 
-Diversity means: different languages, different architectures, different use cases.
+## Path to B (beta)
 
-To reach B:
-1. Deploy on at least 6 external projects that differ meaningfully from each other
-2. Confirm it works in each (or document failures)
-3. Feed back any issues found (GitHub issues or PRs)
-4. Update this file with the evidence
+After C: 6+ diverse external targets tested, issues fed back.
