+String literals the release binary packs against adjacent data with no

+Repaired only where the truncated prefix is already a known variable.

+- `BUN_ENVprocess` -> `BUN_ENV` (prefix is a known variable)
+- `NODE_ENVsec` -> `NODE_ENV` (prefix is a known variable)
+- `NODEreams` -> dropped (prefix `NODE` is not a known variable; not guessed)

+# Claude Code Environment Variables — v2.1.226
+
+Source: `@anthropic-ai/claude-code-linux-x64@2.1.226`, documented from
+string literals in the published release artifact.
+
+- `all_vars.txt` — `process.env.<NAME>` reads, `LC_ALL=C sort -u`.
+- `model_provider_env_strings.txt` — model/provider configuration keys that
+  appear as static allowlist strings rather than direct `process.env` reads.
+
+## Counts (vs v2.1.222)
+
+| Metric | Value |
+|--------|-------|
+| Total vars (`all_vars.txt`) | 570 |
+| Added | 32 |
+| Removed | 1 |
+
+See `new_vs_2.1.222.txt` and `removed_vs_2.1.222.txt` for the full diff.
+
+## Notable Additions
+
+<!-- TODO(review): group the 32 added vars by theme and say what changed. -->
+
+## Notable Removals
+
+<!-- TODO(review): group the 1 removed vars by theme and say what changed. -->
+
+> Note: 1 configuration string(s) referencing an unreleased model codename
+> were held out of the public artifacts. See `_held/` (private, gitignored)
+> and the top-level `FLAGGED.md`.
