Open reports via a clickable http:// link (file:// won't open in chat) - #26

Conversation
…n chat) A file:// link is blocked from opening in the Claude/VSCode chat sandbox, so clicking the returned location did nothing. Serve each report over a tiny loopback web server and hand back a clickable http://127.0.0.1 link that opens the rendered report in the browser — while still surfacing the on-disk location. - export.preview_url(path): lazily start a loopback (127.0.0.1, ephemeral port) static server rooted at the report's directory, on a daemon thread, one per directory; returns an http URL that opens the rendered report on click. - export.open_file(path): OS default open (startfile/open/xdg-open), best-effort, no-op under tests/CI/INVESTO_NO_OPEN. - models: ExportedFile/ExportResult gain open_url; AnalysisReport gains html_report_open_url, alongside the existing file:// location fields. - server: analyze_company and export_report populate the http open link. - cli: --open opens the written report in the default app (a short-lived CLI can't host a persistent server); the output still prints the file location.

What & why
The report tools returned a
file://"open" link, but clicking it does nothing in the Claude Code / VSCode chat — the sandbox blocksfile://from opening a local file. The only link a chat/webview will open ishttp(s)://. So each report is now served over a tiny loopback web server and returned as a clickablehttp://127.0.0.1:<port>/<file>link that opens the rendered report in the browser (PDF opens in the viewer). The on-disk location is still surfaced too.Changes
export.pypreview_url(path)— lazily starts a loopback (127.0.0.1, ephemeral port) static server rooted at the report's directory, on a daemon thread (one per directory), and returns anhttp://127.0.0.1/...URL that opens the rendered report on click. Loopback-only, serves just that directory, best-effort (returnsNoneif a port can't be bound).open_file(path)— OS default open (startfile/open/xdg-open), best-effort, no-op underPYTEST_CURRENT_TEST/CI/INVESTO_NO_OPEN.models.py—ExportedFile/ExportResultgainopen_url;AnalysisReportgainshtml_report_open_url(alongside the existingfile://location fields).server.py—analyze_companyandexport_reportpopulate the http open link.cli.py—--openopens the written report in the default app (a short-lived CLI can't host a persistent server); the output still prints the file location.Verification

The clickable
