@clawsjoy/dsh-session-persistence-tolerant

A listing-tolerance decorator over DSH's official jsonl session backend (@deepseek-ai/dsh-session-persistence-jsonl).

The problem

DSH's session listing reads only each artifact's first frame:

• a frame it cannot decode is rethrown — one damaged log fails the whole listing (and on the boot path, WorkspaceRegistry lists during plugin init, so a failed listing is a failed plugin-tree load);
• a first frame that is not a session header is silently skipped — the conversation leaves the sidebar with no error, no log line, no counter.

Both are invisible in practice: the only symptom is "a conversation is missing".

What this plugin does

It extends JsonlSessionPersistence and overrides the listing path only. Create / append / load / repair / the service key / the config schema all stay the official implementation, so upstream changes to those paths arrive for free.

• On a successful listing, it diffs the listing against a tolerant scan of the root and reports every artifact that was skipped silently.
• When the listing throws, it salvages every listable session instead of returning nothing.
• Faults surface two ways: listFaults() on the service instance, and an append-only JSONL sink (deduped per fault set) so a vanished conversation leaves a trace even when nobody asks.

The scan reads the session id and cwd from the artifact, and only assumes <root>/<project>/<session>/session.jsonl[.zstd] plus "first decompressed line is the header" — so a change to the directory-naming scheme does not break it.

Install

Published on npm as @clawsjoy/dsh-session-persistence-tolerant (MIT, no runtime dependencies):

dsh plugin --profile web add @clawsjoy/dsh-session-persistence-tolerant

Installing straight from this repository works too, so nothing here depends on a registry release:

dsh plugin --profile web add github:ClawsJoy/dsh-plugins#path:packages/session-persistence-tolerant

Swap the official row for this one in ~/.dsh/profiles/web/cordis.patch.yml (the row is disabled, never modified):

- id: session-persistence-jsonl
  disabled: true
- insert:
    - id: session-persistence-tolerant
      name: '@clawsjoy/dsh-session-persistence-tolerant'
      config:
        root: !!js dshHomePath('sessions')

The config is the official backend's schema, unchanged.

Environment

| Variable | Effect | |---|---| | DSH_SESSION_LIST_FAULT_SINK | Overrides the fault sink path (default $DSH_HOME/logs/dsh-session-list-faults.jsonl). | | DSH_SESSION_LIST_TOLERANT=off | Restores the official behaviour exactly — the production negative control. |

Verification

pnpm test

The suite includes the negative control: the same artifact tree that makes the official listing shape throw is the tree this plugin lists and reports.
