Edit a shared deliverable while another live session or a colleague's agent is editing the same file right now — "don't delete each other's work", "only write when the other one is finished". When the file is built from many per item sources by an assembler (sections into one HTML, slides, reports): source mtime shows which items they are on, disjoint sources cannot clobber, and an idempotent rebuild merges everybody's sources. Grepping the assembled build is a false negative test, and staging…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Co-editing a section-assembled deliverable alongside a live parallel session ## Problem The user says: *"a parallel session is making active edits on the same file, so please don't delete each other's work — maybe only write on it when the other one is finished."* The deliverable is large and shared. The naive readings both fail: **serialize** (do nothing until they finish — wastes the session, ignores the user's "fan out / go fast") or **dive in blindly** (and clobber their work, which is exactly what they warned against). There is a third path that is fast AND safe — but only once you notice the build model: the artifact is **assembled from per-item source files**, and the assembler is **idempotent** (reads all sources from disk, regenerates the one output). That changes the collision math entirely. ## Context / Trigger conditions - User warns that another live session / agent is editing the same file; "don't clobber each other"; possibly "only write when the other is finished." - The deliverable is generated: a build script (`_assemble.py`, a bundler, a static-site generator) inlines per-item source files (`sections/*.html`, …

How to install
mdr add wan-huiyan/agent-traffic-control/parallel-session-coedit-via-source-mtime-and-idempotent-rebuild@sha256:477a1edf4910da17The line at the top of this page pins the label v1.2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
