 DeepSeek V4 Pro Iteration (2026-07-15)** below. It improved the earlier local

+
+The final focused continuation reused the 21/22 artifact in the same run

+`B3 / S23` failure, accepted one exact replacement that trimmed the two rule
+halves around `/`, and automatically verified `OK: 22 checks, 0 failures`.
+Because the CLI intentionally enables a post-pass requirements review, the
+model then made one bounded 2K completion call and selected `done` without
+changing the file. The status file records a pass and 1,984 output tokens.
 
 ## Experiment Rules

 calls, costing $0.5718. Together with the earlier unsuccessful 8K experiment,
 this is negative evidence for retaining a model-specific cap. The cap was
 removed; explicit `JCODE_MAX_TOKENS` and configured limits remain available.
+
+### Local Focused Repair Completion
+
+The final local-only workflow pass retained five related changes:
+
+1. A dirty local git worktree is verified before the first provider request.
+2. Local repair turns use a 2,048-token cap instead of 4,096 tokens.
+3. After a verifier-visible `.ss` artifact exists, the provider no longer sees
+   `write`; `edit` is narrowed to required `path`, `old_str`, and `new_str`, and
+   runtime enforcement rejects broad rewrites that bypass the schema.
+4. A successful local edit automatically invokes the configured verifier
+   without asking the model to spend another turn on `verify()`.
+5. Verifier diagnostics promote unique literal failure lines before longer
+   advisory output, preserving exact inputs such as `B3 / S23`.
+
+The same patch also retains transport hardening contributed during the
+iteration: an incomplete OpenAI-compatible stream is rejected unless it ends
+with a finish reason or `[DONE]`, retry classification includes aborted streams,
+and the first truncated local response is allowed one constrained continuation
+before expert escalation. Local requests hide Jerboa MCP schemas when the task
+guidance already contains the required language patterns.
+
+Deterministic coverage exercises dirty preflight verification, the 2K cap,
+schema narrowing, runtime rewrite rejection, literal failure evidence, exact
+repair, automatic verification, truncated-stream retry, and deferred expert
+handoff. The complete suite reports `1217 passed, 0 failed, 1 skipped`.
+
+Live validation used the existing 21/22 artifact under
+`20260715-212140-life-rle-local-ds4-jcode-expertcap`. The installed binary
+verified the dirty tree first, DeepSeek V4 Pro read the existing implementation,
+made one exact replacement, and jcode automatically reached `22/22`. The CLI's
+intentional requirements-review turn then called `done` without another edit.
+This converts the local hard-RLE benchmark from the original 0/22 failure, via
+20/22 and 21/22 intermediate artifacts, to a full public pass.
