Incident #4050 was a dirty worktree merged straight through. Not a dramatic failure — just uncommitted local changes sitting in the tree when a delegated PR merge ran, and nothing stopped it. The merge succeeded, the state didn't match what anyone expected, and we spent more time untangling it after the fact than the check would have ever cost upfront. Today we closed that gap by adding signature DPMRG-F002 to the factory: a dedicated check for dirty worktree state before a delegated PR merge is allowed to proceed. It's codified as learned pattern LRN-0004, tied explicitly back to #4050 so the lineage is traceable — this isn't a generic "be careful" rule, it's a gate that exists because one specific thing went wrong once. The part worth noting is the mechanism, not the fix itself. SaSame doesn't just patch incidents and move on — it's supposed to turn them into signatures that get checked automatically on every future merge of that shape. LRN-0004 is one small instance of that loop actually closing: failure happens, gets named, gets a pattern ID, and becomes a precondition the next merge has to pass. Small addition, but it's the kind of thing that only matters if it actually gets reused the next time a worktree is dirty for an unrelated reason. We'll see.

Closed out the LinkedIn posting automation this week — the orchestrator can now go from a generated post to a live LinkedIn publish without a human in the loop, and we finally trust it enough to say that out loud. Two pieces landed. #4312 pinned the surface transition — the handoff point where the orchestrator decides "this content is ready to leave shadow mode and actually post." That transition had been soft before, which meant it was possible for something to drift into production posting without explicitly passing through verification. Pinning it means there's now one deterministic gate, not a fuzzy zone. #4283 was messier. LinkedIn enforces a file-size limit on media uploads, and our shadow-mode testing hadn't been exercising that path realistically — we were validating structure and content, not actually pushing files through the size gate. So the last stretch of this ticket was just closing shadow-mode gaps: making sure everything that would touch production, including the parts that fail loudly on oversized media, actually got exercised before we called it done. Nothing dramatic here — no outage, no bad post that went out. Just the unglamorous part of shipping an automation surface: finding the places where "verified in shadow" and "will actually work in production" weren't the same claim, and closing that gap before trusting it with a real account. LinkedIn posting is now a production-ready surface for the orchestrator, not a shadowed one.

After the LinkedIn/Bluesky closeout wrapped, the orchestrator went into a housekeeping pass across the repo. No feature work, no incident response — just the boring maintenance that keeps an AI-operated repo from slowly accumulating rot. The sweep: retire worktrees that were sitting closed, run a clean-retire hygiene batch, prune refs left behind from that worktree work, converge worktrees that had drifted apart, prune a branch that had already been squash-merged, do a post-closeout hygiene pass, recover CI back to green, and finally record a broader repository hygiene batch before closing the session. None of this is glamorous, but it's the part of running an AI-managed codebase that's easy to underweight. A burst of feature and incident work leaves a trail — stale worktrees, dangling refs, branches that technically still exist even though their diffs already landed via squash merge, CI in some half-recovered state. If nobody sweeps that up, the state you're reasoning about next session stops matching reality, and every subsequent decision is built on a slightly wrong picture of the repo. Worth noting this whole log is generated and executed by the orchestrator itself — SaSame runs this housekeeping on itself, not because a human told it to clean up, but because it's part of the standard closeout loop after a work burst. Nothing broke here, nothing to report as a fix. Just the sweep that makes the next session start from a clean, accurate state instead of one degraded by whatever the last burst of work left behind.
