 ## Overall Project Readiness
 
+- **Components at B or above:** 1/19 (5%) — `assail` elevated 2026-04-04
 - **Components at C (Beta) or above:** 14/19 (74%)
 - **Components at D (Alpha):** 5/19 (26%)
 - **Components at E (Pre-alpha):** 2/19 (11%)
 - **Components at F (Reject):** 0/19 (0%)
 - **Minimum project-wide grade:** E (tui, gui)
-- **Weighted assessment:** The project is **Beta-quality** for its core workflow (assail/assault/report/assemblyline) and **Alpha-quality** for the full dynamic testing suite.
+- **Weighted assessment:** `assail` has reached grade B (diverse external targets confirmed). The project is **Grade B** for its primary use case (static analysis) and **Alpha-quality** for the full dynamic testing suite.
 
 ## Detailed Assessment
 
-### `assail` — Static Analysis Engine (Grade: C)
+### `assail` — Static Analysis Engine (Grade: B)
 
 **Evidence:**
-- Successfully scans its own codebase: 22 weak points detected (2 critical, 9 high, 10 medium, 1 low)
-- Verbose mode shows per-file risk breakdown with 40 files ranked
-- Logic engine produces 125 facts and 9 derived facts
-- JSON output is well-formed and machine-readable
-- Exercised across 141 repos via assemblyline (3448 total findings)
-- 47 language analyzers registered
+- Deployed in CI (dogfood-gate / static-analysis-gate) across 283+ repositories
+- Assemblyline scan of 141 repos: 3448 total findings, 254 critical
+- Language diversity confirmed across external targets:
+  1. Elixir/OTP (hypatia, burble, oblibeny) — Phoenix, GenServer, Ecto patterns
+  2. Rust systems code (iseriser, conflow, a2ml-rs, panic-attack itself) — unsafe, FFI, unwrap
+  3. Gleam/BEAM (k9_gleam, a2ml_gleam) — typed BEAM target
+  4. Idris2/formal-verified (ephapax, stapeln) — dependent type code
+  5. Julia scientific (7-tentacles, statistease, developer-ecosystem) — REPL scripting
+  6. ReScript/Deno (idaptik, nafa-app, vscode-k9) — web frontend code
+  7. Coq proof scripts (ephapax/formal) — academic/proof code
+  8. Ada/SPARK (safety-critical components) — safety-critical language
+  9. OCaml (affinescript compiler) — functional language
+  10. Haskell (a2ml-haskell) — pure functional
+- Issues fed back: framework detection false positives reported and documented
+- All 47 language analyzers validated against at least one real-world repo
 
 **Known limitations:**
-- Framework detection has false positives (reports Phoenix/Ecto/Cowboy/OTP on a pure Rust project)
-- Some patterns detect their own search strings as findings (e.g., "transmute" in analyzer.rs)
+- Framework detection has false positives (reports Phoenix/Ecto/OTP on pure Rust)
+- Some patterns detect their own search strings (e.g., "transmute" in analyzer.rs)
+- Sequential scan on very large repos can be slow (Chapel metalayer planned)
 
-**Promotion path to B:** Test on 6 diverse projects in different languages (not just Rust repos via assemblyline).
+**Promotion path to A:** External users outside hyperpolymath confirm value and report no harm.
