Fix #2221: Windows: plugin runtime data and paths assume POSIX ~/.hermes instead of HERMES_

[Memtensor-AI]

Description

Fixes #2221 (Windows: plugin runtime data assumes POSIX ~/.hermes instead of HERMES_HOME / %LOCALAPPDATA%\hermes) in the apps/memos-local-plugin Hermes adapter.

Added a single canonical Hermes-home resolver on each language side that mirrors Hermes' own _get_platform_default_hermes_home (HERMES_HOME env → %LOCALAPPDATA%\hermes on win32 with ~/AppData/Local/hermes fallback → ~/.hermes elsewhere): new modules adapters/hermes/memos_provider/hermes_home.py and core/config/hermes-home.ts. All hard-coded ~/.hermes / .hermes sites now route through it: the Python provider _resolved_memos_runtime_home + _extract_child_tool_calls, bridge_client._resolved_runtime_home, bridge.cts::pidFilePath, bridge.mts::pidFilePath, core/config/paths.ts::resolveHome (hermes default), server/routes/migrate.ts::legacyDbPath, and server/routes/import-export.ts::hermesNativeMemoryPath. Non-Hermes agents keep the ~/.<agent>/memos-plugin convention; MEMOS_HOME / MEMOS_CONFIG_FILE still win over HERMES_HOME.

Test evidence: new TDD suite tests/python/test_hermes_home.py (8 tests) and tests/unit/config/hermes-home.test.ts (6 tests) cover all four resolver branches plus the Python provider / bridge_client integration paths. tests/unit/config/paths.test.ts extended with a resolveHome("hermes") + HERMES_HOME regression assertion. Full Python suite passes (109/109), full vitest suite passes (156 files / 1274 tests, 2 pre-existing skips), tsc -p tsconfig.json --noEmit clean. POSIX default (~/.hermes) is preserved when HERMES_HOME is unset, so no behaviour change on Linux/macOS.

1. apps/memos-local-plugin/adapters/hermes/memos_provider/__init__.py (L135)

Finding 9 not fixed: This test remains unreliable on POSIX CI. Path("C:\\Users\\bob\\AppData\\Local").resolve() on Linux/macOS treats the entire Windows-style string as a single filename component and resolves it relative to CWD (e.g. /repo/C:\Users\bob\AppData\Local). After .replace("/", "\\") the result becomes \repo\C:\Users\bob\AppData\Local\hermes, which does end with AppData\Local\hermes — so the assertion passes trivially for the wrong reason, masking any bug where _expand returns a CWD-relative path instead of the intended Windows path. Consider either skipping this test on non-win32 platforms (@unittest.skipUnless(sys.platform == 'win32', ...)) or using a POSIX-shaped LOCALAPPDATA path (e.g. /home/bob/.local) to make the assertion meaningful on all platforms.

---

2. apps/memos-local-plugin/core/config/paths.ts (L69)

Finding #7 is still partially unresolved. String(agent) remains redundant here — agent is typed as AgentKind ("openclaw" | "hermes" | string), which is already a string. The cast adds no value and is inconsistent with the direct agent === "hermes" comparison introduced just above. Replace with the bare agent identifier.

💡 Suggested Change

Before:

    const tmpl = DEFAULT_HOME_BY_AGENT[String(agent)] ?? `{HOME}/.${agent}/memos-plugin`;

After:

    const tmpl = DEFAULT_HOME_BY_AGENT[agent] ?? `{HOME}/.${agent}/memos-plugin`;

---

3. apps/memos-local-plugin/server/routes/migrate.ts (L74)

Previous finding #7 is not fixed: String(agent) is still redundant. AgentKind is typed as "openclaw" | "hermes" | string, so agent is already a string. The explicit agent === "hermes" guard added in the branch above makes it even clearer that agent is a string at this point. The String() wrapper should be removed for consistency and clarity.

💡 Suggested Change

Before:

return join(resolveHermesHome(), "memos-state", "memos-local", "memos.db");

After:

    const tmpl = DEFAULT_HOME_BY_AGENT[agent] ?? `{HOME}/.${agent}/memos-plugin`;

Nice work — the canonical hermes_home.py + hermes-home.ts resolver is a much cleaner systemic fix than the piecemeal approach we started with. Tests (109/109 Python, full vitest) give it good confidence. 👍

One small note for the merge queue: our PR #2211 covers the install-script half of this bug family — install.ps1 writes the Hermes template config to the code dir instead of the runtime home. Since this PR doesn't touch install.ps1, #2211 is complementary rather than redundant; happy to close #2210 / #2225 as superseded by this one.

  • the branch-order test uses str.find("defaultHome") and matches the function parameter/comment before the actual branch;
  • the concurrency test pairs as_completed() results with request paths by enumeration order, so responses are assigned to the wrong endpoint.
• Local plugin validation: Python 117/117, Vitest 1310 passed / 2 skipped, Ruff check/format, lint, and build all passed.

Closing as superseded by #2230, which is merged into main and fixes #2221 with platform-aware runtime-home resolution and regression coverage.
