🔗 feat: Snapshot Files for Shared-Link Attachments (#13740)
* 🔗 feat: Snapshot Files for Shared-Link Attachments

Shared-link viewers could read a shared conversation snapshot but not its
attachments: file preview/download still went through the owner-scoped file
ACL (the /api/files router sits behind requireJwtAuth + owner/agent checks),
so anonymous viewers got 401s and authenticated non-owners got 403s — the
repeated `[fileAccess] denied` warnings seen for the preview poller.

Capture an immutable per-share file snapshot (embedded on the SharedLink
document, referencing the original stored object — no byte copy) at share
create/update, and serve those files through new share-scoped routes
authorized by the existing shared-link view permission (public/ACL) plus
snapshot membership, never the owner's live file ACL.

- data-schemas: fileSnapshots on the share doc; capture in create/update;
  read-time rewrite of filepath/preview to /api/share/:id/files/:fileId;
  getSharedLinkFile + lazy backfillSharedLinkFiles for legacy links
- api: GET /api/share/:shareId/files/:file_id[/download|/preview]; route
  context added to fileAccess denial logs
- packages/api: isFileSnapshotEnabled resolver (env + yaml)
- data-provider: interface.sharedLinks.snapshotFiles (default on) + client
  endpoints/services
- client: ShareContext.shareId wired to Image, preview hook, and downloads
- config: SHARED_LINKS_SNAPSHOT_FILES env override (default on)

* 🔒 fix: Address Codex review on shared-link file snapshots

Triage of the Codex review on PR #13740 (2 P1, 7 P2 — all valid):

- P1 (cross-user access): scope the snapshot lookup to the sharing user's own
  files so a message referencing another user's file_id can't widen access.
- P1 (stored XSS): the inline share-file route now serves only safe preview
  types inline (raster images/pdf); everything else is forced to attachment with
  X-Content-Type-Options: nosniff.
- Stream shared downloads by default; redirect to a signed URL only on
  ?direct=true (blob/XHR callers work without bucket CORS).
- Read preview status live from the file record (always current for deferred
  previews) and stop embedding extracted text in the share doc (16MB-limit risk).
- Only lazily backfill when the fileSnapshots field is absent (legacy), not on
  every snapshot miss.
- Backfill legacy shares before rewriting message URLs, and gate URL rewriting
  to public shares so non-public (ACL) shares keep prior behavior (img/anchor
  can't carry the bearer token).
- Frontend: only route a download through the share path when the file was
  actually snapshotted (rewritten href / filepath), else fall back.

* 🔑 feat: Authorize shared-link files for non-public shares via cookie

Extends shared-link file access to non-public (ACL) shares (Codex finding 5).
`<img>`/anchor requests can't carry the bearer access token, so non-public
shares previously 401'd on file loads. Add an optional cookie-auth fallback on
the share file routes that resolves the viewer from the `refreshToken` cookie
(or signed `openid_user_id` cookie) — the same mechanism secure image links use
(validateImageRequest) — then let canAccessSharedLink run the viewer's ACL check.

- new middleware optionalShareFileAuth (+ unit spec); applied to the three
  share file routes after optionalJwtAuth
- URL rewriting in getSharedMessages is no longer gated to public shares (the
  route now authorizes header-less requests), so files work uniformly across
  public and non-public shares; revert the now-unused req.sharePublic plumbing

* 🔒 fix: Second Codex pass on shared-link file snapshots

Addresses the follow-up Codex findings on PR #13740:

- Don't snapshot transient text-source files: FileSources.text filepaths are
  Multer temp paths the upload route deletes, so they can't be streamed —
  removed from the streamable allowlist.
- Unset stale snapshots on a disabled-feature update: updateSharedLink now
  $unsets fileSnapshots when snapshotFiles is false, so an opted-out update
  can't keep serving file ids the update dropped.
- Load tenant config after share resolution: configMiddleware now runs after
  canAccessSharedLink (which enters the share's tenant ALS context), so
  per-tenant interface.sharedLinks.snapshotFiles overrides apply to anonymous
  public views.
- Return a clean 404 when the snapshotted object is gone: resolveShareFile now
  requires the live file record and 404s if it's been deleted/expired, instead
  of letting the stream error after headers are sent (ENOENT / 500).

(The re-flagged P1 about private-viewer rewriting was already fixed in the prior
commit's cookie-auth change.)

* 🔒 fix: Third Codex pass on shared-link file snapshots

Addresses the third Codex review pass on PR #13740:

- P1: keep shared previews/files pinned to the snapshotted version. Snapshot the
  small previewRevision; resolveShareFile 404s when the live file's revision no
  longer matches (file_id reused/overwritten by a later turn), so old links can't
  surface post-share content — covers both preview text and streamed bytes.
- Honor the toggle as a kill switch: resolveShareFile 404s when snapshotFiles is
  disabled, instead of only skipping backfill, so disabling stops serving
  already-snapshotted file URLs.
- Lazy-sweep orphaned 'pending' previews to 'failed' in the share preview route
  (mirrors the owner route) so the client poller reaches a terminal state.
- Resolve the cookie-fallback user in runAsSystem so strict tenant isolation
  doesn't throw before canAccessSharedLink establishes the share tenant context.

*  feat: Per-link "share files" checkbox for shared links

Add a checkbox to the share-link dialog (checked by default) letting the user
choose whether to include the conversation's files in the shared link, with
copy explaining images/files won't be visible to viewers otherwise. Opting out
skips snapshot creation/serving for that link.

- client: ShareButton renders the checkbox gated on the new
  startupConfig.sharedLinksSnapshotFilesEnabled flag; state threads through
  SharedLinkButton into the create/update mutations as `snapshotFiles`.
- data-provider: createSharedLink/updateSharedLink send `snapshotFiles` in the
  body; TStartupConfig gains `sharedLinksSnapshotFilesEnabled`.
- api: POST/PATCH /api/share compute snapshotFiles as
  isFileSnapshotEnabled(req.config) && body.snapshotFiles !== false (admin gate
  AND per-link opt-out); config.js exposes the effective enabled flag to clients.
- en locale: com_ui_share_files (+ _description).

* 🐛 fix: Make the "share files" opt-out actually hide files

Unchecking "share files" at creation didn't hide anything: the shared message
JSON still carried each file's original (e.g. static-served) path, and because
opting out only meant "no fileSnapshots field" — indistinguishable from a legacy
link — getSharedMessages would backfill snapshots on first view whenever the
admin feature was on, re-enabling files entirely.

Fix by persisting and honoring the per-link choice:
- Store `snapshotFiles` (boolean) on the SharedLink so opt-out is distinct from a
  legacy link; set it on create and update.
- getSharedMessages computes includeFiles = adminEnabled && link not opted out;
  when excluded it strips files/attachments from the payload (no original-path
  leak) and never backfills the opted-out link.
- Surface the stored choice via getSharedLink so the dialog checkbox reflects an
  existing link's actual setting instead of always defaulting to checked.

Note: changing the checkbox on an already-created link still applies only when
the link is refreshed (which regenerates the URL) — a UX follow-up.

* 🔒 fix: Close remaining shared-link file opt-out leaks (Codex)

Follow-up to the per-link opt-out, addressing the third Codex pass:

- Honor the opt-out on the file route too: getSharedLinkFile now returns the
  link's `optedOut` choice; resolveShareFile 404s (and never backfills) an
  opted-out link, so a direct /files/:id request can't re-create snapshots.
- Make read/serve viewer-independent: the gate no longer uses the viewer's
  resolved config (isFileSnapshotEnabled(req.config)) — it uses the link's stored
  choice plus a global env-only kill switch (isFileSnapshotKillSwitchActive). A
  viewer's own interface.sharedLinks.snapshotFiles can no longer hide a link's
  files. Create/update still use the creator's config to set the per-link choice.
- Neutralize render URLs for non-snapshotted files: applyShareFileRoute now
  strips filepath/preview for any file/attachment not in the snapshot, so the
  owner's original (e.g. static) path can't be loaded through the share.

* 🔒 fix: Harden shared-file version pinning and local path handling (Codex)

- Refuse reused/overwritten file snapshots more broadly: resolveShareFile now
  refuses to serve when either previewRevision OR `bytes` changed vs the
  snapshot. `bytes` catches non-office reused outputs (e.g. code-exec
  same-filename images that lack previewRevision) and is stable across S3 URL
  refresh and the pending->ready transition. Same-size content swaps remain a
  best-effort gap inherent to the no-byte-copy design.
- Strip cache-busting query strings before local streaming: code-output images
  add `?v=...` to filepath; the share route now splits it off so getLocalFileStream
  resolves the real filename instead of a literal `*.png?v=...` path.

* 💬 fix: Clarify that file-sharing changes apply on link refresh

For an already-created shared link, changing the "share files" checkbox only
takes effect when the link is refreshed (which regenerates the snapshot). Add a
note under the checkbox, shown only when a link already exists, so the behavior
isn't surprising: "Refresh the link to apply this change — files are snapshotted
when the link is refreshed."

# # Model Configuration - Set Visible Model Names and Deployment Mappings
# # Similar to Azure OpenAI model naming pattern
# # ============================================================================
#
# # Option 1: Simple array (legacy format - model name = deployment name)
# # Use this if you want the technical model IDs to show in the UI
# # models:
# # - "claude-fable-5"
# # - "claude-opus-4-8"

# # - "claude-3-5-sonnet-v2@20241022"
# # - "claude-3-5-haiku@20241022"
#
# # Option 2: Object format with custom visible names (RECOMMENDED)
# # The key is the visible model name shown in the UI (can be any name you want)
# # The deploymentName is the actual Vertex AI model ID used for API calls
# # You can use friendly names (avoid spaces for cleaner YAML) or technical IDs as keys
