dsh-tavern

dsh-tavern

The tavern for DeepSeek Harness: a full central page, character cards, world info — and it bundles dsh-group-chat so one install gives the whole thing.

Status: skeleton. The binding table is real and tested; the books, cards and engine behind it are not written yet.

The one structural idea worth reading

src/bindings.ts is the answer to the previous project's most expensive bug.

There, one table held "the books bound to target X", and two legitimate writers used it: the group lifecycle (adding its own book on start, removing it on stop) and a human editing the binding overview. The overview saved a whole row from a snapshot taken earlier, so a save silently deleted whatever the lifecycle had added in between. It was found, fixed on one side, and found again from the other. Two audits, two packages, one lost-data path — and the fix that finally held was a rule for humans, which is exactly the kind of rule that gets forgotten.

Here, ownership is structural: every row is keyed by owner + target, and no operation can reach another owner's row. The clobbering write is not discouraged, it is unrepresentable. Injection resolves the union of the rows.

node --test tests/*.test.ts     # 15 assertions, the first one being the invariant

What exists

• src/bindings.ts — binding rows, ownership isolation, deterministic resolution order.
• src/domain.ts — the durable tavern_seat table.
• src/index.ts — ctx.tavernContextSeat: addBinding / removeBinding (owned by group chat), setUserBinding (owned by the human), setTavernBinding (owned by the tavern), and booksFor(target).
• src/client/index.tsx — claims main with its own key plus a sidebar.panellist icon, giving the tavern a whole page rather than a settings dialog. The previous project put everything in settings.section, inside a fixed-width container with overflow: hidden — which cost two review rounds of max-width patching, one selector at a time, and never left room to be a tavern.

What does not exist yet

Books, the world-info engine, character cards, prompt injection. Specifically, ContextSeatSeam.mount is declared in the contract but deliberately absent from the service — nothing injects into a prompt yet, and a no-op that returned a disposer would look like it worked. A loud absence beats a silent one.

Installing

dsh plugin --profile  add ./packages/tavern

This is the aggregate: its patch inserts both its own row and dsh-group-chat's. Install it or dsh-group-chat alone, never both.
