From 1b1249f5f17ee0362d98eb7cdffc48ebfaecfd2d Mon Sep 17 00:00:00 2001 From: Maggie Appleton <5599295+MaggieAppleton@users.noreply.github.com> Date: Mon, 12 Oct 2026 10:23:44 +0100 Subject: [PATCH 01/18] Build a delivered plan's later changes on demand without LIVE_BUILD A browser build that delivers now records its built source in manual mode, so edits read as "N changes to build". The capsule's Build queues one rebuild of those edits onto the existing pull requests on the presser's own agent, reusing queueRebuild without LIVE_BUILD's automatic trigger. Retry on a failed rebuild uses the same route.

The press is the approval for the rebuild's tasks, now documented at reportRebuild, in the lifecycle docs and in AGENTS.md. A manual live record restores only for a delivered run. A refused Build shows inline (on a phone, Build opens with it) and clears once the changes build. On a phone the action reads "Build changes", and only people who can build are told it runs on their agent. A server test now runs read_rebuild and report_rebuild without LIVE_BUILD.

Rebuild refusals read through the shared copy mapper. Cancelling a waiting Build plan refuses an archived document.

It judges at most five unseen prose blocks per scan with one Jev noul each (>= 0.6; explicit-uncertainty matching when Jev is absent or fails) and keeps at most three spikes active. A hit becomes an investigation marked as a spike, attributed to the last editor and authorized on that person's live repository connection; with no connection nothing is created. A "Prototyping…" Callout is placed directly under the passage after the record persists, and is rewritten in place when the spike completes or stops. Removing the callout dismisses the spike, and a passage whose digest has a spike never re-triggers. Spike runs get run-scoped upload_investigation_image and submit_spike_result tools; the server builds the report from the headline, findings, recommendation and uploaded images. Spikes stay out of the investigation list.

A spike run whose agent accepts HTTP servers now gets a per-run streamable-HTTP bridge on 127.0.0.1, guarded by a random bearer token and closed with the run, that relays the run's Chopin tools and adds upload_image_file. Agents without HTTP support keep the stdio bridge. A scan that stopped at the active-spike cap never judged the waiting passages until another edit. It now resumes when a spike record changes.

Without Jev nothing is spiked unless LIVE_SPIKES_REGEX_JUDGE=on. Spikes are capped per document and per editor each hour and interrupted 20 minutes after their claim. A spike run cannot submit an investigation or experiment result. A finding no longer lands under a queued first build by moving its approved graph to a new revision: any build lock defers the callout until the build ends. The connector runs a spike under Git configuration that refuses every push and removes its worktree and branch afterwards. Callout deletion is detected anywhere in the tree, a placement that throws gives its slot back, image uploads check size before reading, and a file named ..shot.png is no longer mistaken for one outside the worktree.
