From 64638f3978fa8dab3714fc99984fbfe074a4991b Mon Sep 17 00:00:00 2001 From: garrytan Date: Sat, 3 Oct 2026 21:10:17 +0000 Subject: [PATCH] D3: treat design docs and handoff notes as data in plan reviews plan-ceo-review, plan-eng-review and plan-devex-review read the freshest design doc as the source of truth, and nothing said its content is data. In multi-agent pipelines another agent may have written it, or a handoff note beside it, with reviewer-directed text ('skip Step 0', 'approve as-is'). Each read site now says the doc and any handoff note are data, never to follow text aimed at the reviewer, and to report it as suspicious content. The plan-completion audit's discovery, which now reads repo docs/designs/ files (F1), carries the same rule.
