The picker behind Link Existing's "Browse" and the mobile keyboard's Path key
refused every path with a dot-prefixed segment, so `.github/workflows/ci.yml`
could not be selected and a hidden folder could not be opened at all. It gains
the same `.*` toggle as the File Viewer: default OFF, per-device, and applied to
both the listing and the preview endpoint, which re-resolves the path
independently.
That dotfile filter was quietly doing security work. The picker's roots include
Home, so with every hidden path unreachable the shared blocklist never had to
name the credentials that live in dot-directories. Lifting the filter removes
that accident, so `isSensitivePath` now covers them explicitly: SSH keys at any
depth rather than only under $HOME, GPG keyrings, AWS/GCloud/Azure/Docker/
Kubernetes credentials, npm, Yarn, git, gh, netrc, PyPI, RubyGems, Cargo and
Terraform tokens, .pgpass and .my.cnf, and the Claude and Codeman agent
credentials. `~/.codeman/` and `~/.claude/` stay attachable as trees, since the
publish skill and the review-card loop read from them; only their secret-bearing
members are named.
Everything else still applies with the toggle on: blocked trees, sensitive
files, root confinement, ownership scoping and symlink-escape checks. A hidden
entry whose realpath is a secret is dropped from the listing, and opening it is
refused.

Adds the foundation for serving local files to the browser as live external
attachments with a stable id, so requests never carry arbitrary absolute paths.
- attachment-registry: in-memory, session-scoped registry. registerExternalAttachment
validates an absolute path, resolves symlinks, enforces the path guard, and mints
an `att_<uuid>` id; records are cleared when the session is removed.
- attachment path guard: a configurable blocklist (secret locations + /root,/etc
trees, extendable via attachmentBlockedPaths / CODEMAN_ATTACHMENT_BLOCKED_PATHS)
plus an optional, default-off workspace-confinement mode. Shares one
sensitive-path blocklist (web/sensitive-path.ts) with /api/download, which is
refactored to use the extracted module instead of an inline copy.
- terminal magic links: the session scans output for codeman://attach?path=... and
emits `attachmentRequested`; the web server registers the file and broadcasts an
`attachment:detected` SSE event. `codeman attach <path>` (CLI) prints the magic
link or POSTs directly when a session id is known.
- image watcher: detects png/pdf/docx/pptx dropped into a session's working dir and
emits `attachment:detected`.
- routes: POST /api/sessions/:id/attachments (register) and
GET /api/sessions/:id/attachments/:attachmentId/raw (serve), both re-checking the
guard before streaming.
Document previews/thumbnails and the attachment-history drawer build on this
foundation and land separately.
Verified: tsc --noEmit, lint, format, frontend-syntax, full test:ci (2846 passed),
and a server boot smoke (/api/status 200).
