dsh-plugin-turn-memory

The active implementation is being rebuilt from the researched agreements in design.md. The previous implementation is retained under obsolete/ for investigation only.

The current smoke slice implements D-002's isolated in-memory node editor and four fork-only tools. It is disabled by default; the e2e overlay explicitly enables it with a controlled turn-selection and two-pass prompt so those test rules cannot become accidental product behavior.

Verification workflow

Run the fast deterministic checks after every edit:

pnpm check

Run the real end-to-end smoke when the change touches plugin wiring, prompts, tools, surface landing, or persistence:

pnpm e2e

When production prompt behavior changes, also run the qualitative steer regression:

pnpm e2e:prompt

This creates a real multi-step turn whose first /repo attempt fails and whose later user steer says playground. Unlike the deterministic smoke protocol, it uses the production compression prompt and requires the two user messages to become one corrected intent whose provenance includes both sources. Assistant work may remain in more than one semantic node, but together it must retain both the failed detour and the final 6-type/9-device conclusion. It checks live folding, persistence, cold loading, and session-query projection, then writes .tmp/prompt-eval-surface-<session-id>.json for inspection.

The e2e workflow uses the dedicated ~/.dsh/profiles/test-turn-memory profile and the configured real model. It creates a fresh parent session, forces a multi-node tool turn, waits for the turn-end fork to perform n* -> r1 -> r2, lands the actual replacement, checks live foldSurface() and deriveMessages(), flushes persistence, destroys the live agent, cold-resumes the same session, and repeats the projection checks. Success ends with E2E_RESULT=PASS, prints the retained test session id, and writes the exact sessionQuery.readSurface() snapshot to .tmp/e2e-surface-<session-id>.json. The E2E_SURFACE_PATH output contains its absolute path for direct inspection.

The runner requests shutdown through DSH's bounded appExit service rather than calling process.exit(), so persistence and plugin teardown are drained.

Every enabled turn-memory instance also flushes and writes its complete folded surface after a successful replacement. By default the latest snapshot for each session is written to .tmp/e2e-surface-<session-id>.json beside this plugin; surfaceDumpDir changes the destination but leaving it unset does not disable the dump.
