+# ✅ CLOSED 2026-09-20 — every phase done, and the two human decisions taken
+
+Nothing on this page is outstanding. It is kept as the record of how the two-repo
+layout was reached; **where it describes the repository's present state it is
+now out of date on purpose**, and the notes below say how.
+
+| the page says | what is true now |
+|---|---|
+| "**Still open, for the human**: the history fork" | **Taken: full purge.** `git filter-repo` stripped 182 assets from every commit; force-pushed 2026-09-19. `main` `2a93be99` → `e16556dc`, `.git` **217 MB → 114 MB**, **0** assets anywhere in history, verified from an independent fresh clone. Backups + runbook: `~/sylph-repo-backup-2026-09-19/` |
+| "`docs/re/captures/` is 118 MB of game screenshots inside a public repository" | **Decided (#49): no game assets in the repos.** Captures live on disk, gitignored, shared between the host and both agents by bind mount; derived measurements (csv/tsv/txt/log/json/npy) stay tracked. PR #59 |
+| "all six repos are `private=False`" | Still true, and now deliberate — there is nothing game-derived in them |
+| "`ai-agent-*.md`, `scratch/`, `_voice_span.rs` — keep or drop" | `scratch/` and `_voice_span.rs` dropped in the 2026-09-18 cleanup; the `ai-agent-*.md` files are the human's and stay |
+| the four archived repos | unchanged: `Sylpheed-Godot`, `xenia-rs`, `xex2tractor` archived read-only, `Syplheed-Reborn` deleted. ⚠️ Their local clones are **gone from this machine** too, and `sylph-decoder` no longer mounts `xenia-rs` |
+
+🔴 **The one thing this page got right and nobody acted on.** It named
+`crates/sylpheed-export`'s dependency on **this repository by tag** as the hard
+blocker for a rewrite. It was not re-checked before the purge, the locked rev
+vanished, and the build broke for every clean checkout while still working on the
+machine that did the rewrite — its `~/.cargo/git` still held the old object.
+Fixed in PR #60 (re-lock) and PR #61 (path dependency, which removes the class).
+**Before any future history rewrite, grep for a dependency on the repo's own URL.**

+🔴 **Why it has to exist.** Each agent works in its OWN clone, so before issue
+#49 the transport for evidence was *git*: commit the screenshot, the other agent
+pulls it. #49 removed that — captures are gitignored now — and without a
+replacement a capture written in one container is invisible to the other agent,
+to the human, and to `check-capture-citations`, which would call every citation
+dangling. One host directory shared by all three restores it: the same file is
+live everywhere, every `docs/re/captures/...` citation resolves, and nothing can
+reach git history. Read-write on both, because showing each other a screenshot
+is the point.
+
+Verified rather than assumed: container A wrote a `.png` there, a **separate**
+container B read it back, the host saw it, and `git status` reported **0**
+changes.
+
+⚠️ **Evidence that must cross MACHINES still cannot go this way** — a bare clone
+on the other desktop has no captures at all. Attach it to the issue or PR; that
+is the only channel that travels.
+
+⚠️ **The agent volumes were all deleted in the 2026-09-18 cleanup** and Docker
+recreates them empty on next launch. Nothing was lost — both agent clones were
+verified clean with nothing unpushed, and the exchange held only spent artefacts.
+One side effect is welcome: the empty `*-claude` volumes mean the next launch
+starts a **fresh** session, which is the documented workaround for the
+"resumes the old brief" defect below.
+
+⚠️ **`sylph-decoder` used to mount `xenia-rs` read-only. That repo is retired and
+the directory is gone**, so the mount pointed at nothing; removed.

 **Credentials** — three files on the host, `chmod 600`, mounted read-only:
