claude_code_agent: project_key regex keeps "." but Claude Code replaces it — watcher tails a directory the CLI never writes to

[apakkhalin-sudo]

Env: OpenCompany 0.1.1 (npm @zeenie-ai/opencompany), Windows 11, Claude Code CLI 2.1.261, isolated CLAUDE_CONFIG_DIR.

_PROJECT_KEY_RE preserves ., but Claude Code does not — it maps every character outside [a-zA-Z0-9-] to -, dots included.

https://github.com/zeenie-ai/OpenCompany/blob/main/server/services/cli_agent/session.py#L63

_PROJECT_KEY_RE = re.compile(r"[^a-zA-Z0-9.-]")   # keeps "."
...
project_key = _PROJECT_KEY_RE.sub("-", str(cwd))  # session.py:443

Any worktree path containing a dot therefore resolves to a directory Claude never writes to. The default layout has one — .opencompany:

cwd	E:\Kae\.opencompany\workspaces\default\cc_test_1\wt_t_bd5e9c51
OpenCompany watches	projects\E--Kae-.opencompany-workspaces-default-cc-test-1-wt-t-bd5e9c51
Claude actually writes	projects\E--Kae--opencompany-workspaces-default-cc-test-1-wt-t-bd5e9c51

_await_first_jsonl then times out and the node fails with "claude may have failed to start or the CLAUDE_CONFIG_DIR is misconfigured", while the CLI has in fact started and answered normally. Confirmed by reading the session JSONL in the dashed directory: correct response, stop_reason: end_turn.

Fix: drop the dot from the class so it matches the CLI's own sanitizer.

_PROJECT_KEY_RE = re.compile(r"[^a-zA-Z0-9-]")

Worth adding a regression test with a dotted path segment — every default install hits this, since the data dir itself is .opencompany.
