From 7c0335495fbbe1b781f321dee96cf0b4a829235d Mon Sep 17 00:00:00 2001 From: KT <677465+kevintseng@users.noreply.github.com> Date: Wed, 13 May 2026 01:16:33 +0800 Subject: [PATCH 01/12] feat(llm-client): validate response shape so failover engages on parse drift Previously a malformed 2xx body (missing field, renamed key, HTML error page returned as JSON) was silently extracted as an empty string and the cross-provider failover chain treated that as success. A broken upstream could block the chain from advancing. Add LLMResponseParseError, classified as 'parse' so the chain continues on the next provider. Shape validators read each provider's response with type guards instead of unchecked casts; an unexpected shape throws and surfaces in telemetry. An intentionally empty string is still treated as a successful call (matches prior caller contract). --- src/core/llm-client.ts | 117 ++++++++++++++++++++++++++++++++-- tests/core/llm-client.test.ts | 85 +++++++++++++++++++++++- 2 files changed, 195 insertions(+), 7 deletions(-) diff --git a/src/core/llm-client.ts b/src/core/llm-client.ts index bd8aef1a..9feb0743 100644 --- a/src/core/llm-client.ts +++ b/src/core/llm-client.ts @@ -46,8 +46,23 @@ export type LLMErrorClass = | 'upstream' // 5xx / 503 — provider outage; another provider may help | 'bad_request' // 4xx (not 401/403/429) — prompt itself is broken; do NOT retry | 'network' // DNS / connection / timeout — another provider may help + | 'parse' // 2xx body did not match expected shape — provider drift; another provider may help | 'unknown'; // unclassified — conservatively retried +/** + * Thrown when a 2xx provider response cannot be coerced into the + * expected shape (e.g. provider drift, HTML error page returned as + * 200, JSON whose top-level field renamed).

Requests larger than this receive a structured `413 Payload Too Large` response: + +```json +{ + "success": false, + "error": "Request body exceeds the 1MB limit", + "code": "PAYLOAD_TOO_LARGE", + "limit": "1mb", + "hint": "Split large exports/imports into smaller batches, or compress and stream them via the CLI (`memesh export` / `memesh import`) which has no per-request size cap." +} +``` + +The limit protects the server from accidentally parsing large payloads (e.g. an unbounded `/v1/import` with a multi-MB JSON bundle) under memory pressure. For bulk operations that exceed 1 MB, prefer the CLI: `memesh export > bundle.json` and `memesh import bundle.json` read and write files directly without buffering the whole payload through Express's body parser, so they have no per-request size cap. + | Method | Endpoint | Description | |--------|----------|-------------| | GET | /v1/health | Health check + version + entity count | From 3266d171e3ea85118179216a5f435dae0c7e417c Mon Sep 17 00:00:00 2001 From: KT <677465+kevintseng@users.noreply.github.com> Date: Wed, 13 May 2026 01:17:08 +0800 Subject: [PATCH 06/12] chore(ci): hard-gate lint at zero warnings 'npm run lint' now carries --max-warnings 0 directly, and CI runs it as a hard step before typecheck (lint is faster, so fail-fast cuts CI minutes on bad PRs).

Drift of 2+ headings (after ±1 translation tolerance) raises WARN; missing locales raise WARN; missing `README.md` skips silently. Fenced code blocks are ignored when counting so example markdown doesn't inflate the count. +- **`memesh kg backfill-relations --reset-idempotency`** — clear the persistent processed-orphan cache before running, so every orphan is reconsidered from scratch. Useful after schema changes or when you want a clean re-evaluation. + +### Changed +- **LLM client now classifies malformed 2xx responses as recoverable** (`src/core/llm-client.ts`) — a body with missing or renamed fields, or a non-JSON body returned as JSON, raises a `parse` error so the cross-provider failover chain advances to the next provider instead of returning an empty string and treating it as success. An intentionally empty string from a provider is still a successful call (existing caller contract preserved). +- **`memesh kg backfill-relations` skips already-considered orphans** — the orphan-id cache lives in `memesh_metadata` under key `kg_backfill_processed_v1`. Reruns no longer pay the tokenisation and scoring cost for entities the command has previously inspected. Use `--reset-idempotency` to opt out. +- **HTTP body-limit response is now structured JSON** (`src/transports/http/server.ts`) — requests exceeding the 1MB body cap get `{ success: false, code: "PAYLOAD_TOO_LARGE", limit: "1mb", hint: ... }` instead of Express's default HTML error page. CLI export/import is unaffected (no per-request cap). +- **Lint runs at `--max-warnings 0` by default** (`package.json`, CI) — new lint warnings now block PRs. The redundant `lint:strict` script has been removed.

That depends on npm reachability, build tools on the user's machine, and a clean npx cache; any one of those failing left users with a -32000 "failed to reconnect" error and a broken plugin install. Move to a self-contained plugin layout: - Track compiled dist/ in git so a plugin clone is runnable without a build step. Adds ~1.7 MB to the repo. Contributors who touch src/ must run 'npm run build' before committing. - dashboard/dist/index.html (~380 KB Preact build) tracked for the same reason — 'memesh serve' works on a fresh plugin install. - .mcp.json points at the plugin cache's local launcher.js. The launcher already has self-healing better-sqlite3 binding rebuild (shipped in v4.2.2), so a missing native binding still recovers automatically without depending on npx or npm registry access. ---

The redundant `lint:strict` script has been removed. CI runs lint before typecheck for faster fail-fast. ### Fixed +- **Plugin marketplace installs now work without npm/npx** (`.mcp.json`, `.gitignore`, `dist/`, `dashboard/dist/`) — Claude Code's plugin marketplace does not execute npm scripts on install (security model), so the previous setup left users with `-32000 "failed to reconnect to plugin:memesh"` because `dist/` was gitignored and the MCP server was re-installed via `npx` on every start. Compiled `dist/` and the dashboard build are now tracked in git so the plugin is runnable on clone. `.mcp.json` points at the plugin cache's local launcher.js, which already self-heals a missing better-sqlite3 binding via in-process rebuild (v4.2.2 work). +- **Dashboard launcher no longer invokes a shell** (`src/cli/view.ts`) — CodeQL flagged the Windows code path as `js/shell-command-injection-from-environment` / `js/indirect-command-line-injection` because `cmd.exe /c start ` re-parses the path through cmd's shell parser, and `MEMESH_DIR` can feed into that path. Windows now dispatches via `rundll32.exe url.dll,FileProtocolHandler` (no shell). macOS `open` and Linux `xdg-open` are unchanged. - **F15 doctor test now inspects the actual corruption fixture** (`tests/core/doctor.test.ts`) — the "provides actionable fix commands for all failure modes" test uses the `MEMESH_DB_PATH` env override (matching every sibling F15 test) so doctor inspects the test database instead of falling through to the default path. ### Documentation diff --git a/dashboard/dist/index.html b/dashboard/dist/index.html new file mode 100644 index 00000000..47dfbc48 --- /dev/null +++ b/dashboard/dist/index.html @@ -0,0 +1,34 @@ + + + + + + MeMesh LLM Memory — Dashboard + + + + + + + + + +
