From c1e22779aed9a0911825a85a3ccabe26102290d2 Mon Sep 17 00:00:00 2001 From: mchwang Date: Sun, 27 Sep 2026 01:15:27 -0700 Subject: [PATCH 1/2] F2a: execute/fix prompts, hostile-issue eval set, and the post-run audit prepareExecution builds the trusted execute/fix request: untrusted issue, plan fields, lessons and problem text only in escaped JSON data blocks, filled in one pass; approvedArgv only from the item's structured cmd checks that exactly match an approved argv. auditRun is a pure audit over D's change manifest (#66): safety violations first (metadata, .git, link targets, gitlinks, new or converted symlinks, unsafe targets, odd entries, oversized reports), then in-scope versus out-of-scope files for the commit step.

The coordinator gains an async finish step and a release step after the terminal write; settleAttempt records the owned ledger entry with completed in the same transaction. A safety violation moves the task to needs human; out-of-scope files are committed and pause it in needs amendment with a checkpoint. The workspace is D's (#66), faked here.
