session_projcache.json. The write path serializes the whole per-session checkpoint in one JSON pass: if a single projection unit stores a non-JSON value (a Map, Set, class instance, cyclic or non-finite value — e.g. some third-party plugins), the entire write fails. The failure is fail-soft (log-only), so the cache silently stops updating. After a restart, every cold session loses its title projection and the UI falls back to showing the workspace folder name instead of the conversation title. ## What this plugin does 1. Per-row degradation (runtime wrapper). It wraps sessionProjectionCache.put() and drops only the rows that are not lossless JSON, keeping every healthy row durable. One bad unit can no longer stall the whole cache — titles, sessionListMetadata, stats etc. keep writing normally. 2. Startup self-heal. On startup it scans persisted sessions whose cached title is missing and cold-reads their logs to backfill the title projection, so an already-stale cache recovers automatically. 3. Observability. A read-only GET /projection-guard/status route reports wrapped-put call counts, dropped rows, and repaired titles (also shown as a small card in Settings when the client half is mounted). No official or third-party files are modified — the guard is a pure runtime wrapper, so it survives dsh upgrades and works on any deployment. ## Install sh dsh plugin --profile web add github:DamonKoy/dsh-projection-guard Restart dsh web. That's it. Or add the repo as a profile dependency and include the bundle: json { "dependencies": { "dsh-projection-guard": "github:DamonKoy/dsh-projection-guard" }, "dsh": { "profile": { "bundles": ["dsh-projection-guard"] } } } Then pnpm install in the profile directory and restart dsh web. ## Configuration | Key | Default | Meaning | | --- | --- | --- | | repairOnStart | true | Backfill missing cached titles from persisted logs at startup. | | logDropped | true | Warn per dropped non-JSON row (key + session id). | Example (profile cordis.patch.yml overlay): yaml - id: projection-guard config: repairOnStart: true logDropped: true ## Development sh npm test # unit tests for the guard core ## License MITNot by stars — picked by hand, one at a time.
A visual settings dashboard for DeepSeek Harness: every registered settings namespace — including third-party plugin ones the official UI never covers — rendered as editable, schema-driven forms. Early, but the right direction: stop hand-editing YAML.
A DIY trajectory visualizer for DeepSeek Harness: watch the agent’s plan and execution unfold as a graph instead of scrolling raw logs. Early, but it fills a real gap — understanding at a glance what the agent is doing.
Dispatch DSH work from Claude Code / Codex: spin up in-host DSH agent sessions with per-tier presets, watch native subagent progress, and borrow a multimodal bridge that lends the text-only harness vision and image generation. An orchestration plugin that turns DSH into a backend for other coding agents.
