feat: add one-tap photo uploads to bridge view by Amplify-Logic · Pull Request #85 · Amplify-Logic/firstmate

Amplify-Logic · 2026-08-19T11:58:03Z

Intent

Add a one-tap photo drop to the existing Starship bridge view so the captain can send photos from his phone (for example scoring photos of a board game through his glasses) with one tap.

The bridge view (merged via #84: bin/fm-bridge-view.py, tests in tests/fm-bridge-view.test.sh, docs in docs/bridge-view.md) stays the same file/module conventions and the same passcode login. Add to that existing server:

Upload UI: a "send a photo" affordance on the authenticated glance page - a file input (accept images, capture allowed) plus submit; phone-first. Show a clear success/failure state and the count of photos received today.
Upload endpoint: authenticated POST only (same session cookie + Origin/Host checks as login), multipart or raw body; accept only image content types (jpeg/png/heic/webp), verify magic bytes not just the header; size cap 15 MB; write atomically into data/bridge-inbox/ (create mode 0700) with a timestamped name plus a sidecar .json (received-at, original name, size, content type). NO other write paths - the read-only guarantee of every other route is untouched, and the snapshot subprocess protections stay as they are.
Safety: uploads never overwrite (unique names), the directory is quarantined storage only (nothing executes or parses image contents server-side beyond magic-byte sniffing), per-session rate limit (e.g. 30 uploads/hour), and the endpoint returns 413/415/429 correctly. Update the CSP if the form needs it, keeping the hashed/nonced approach.
Tests: unauthenticated upload rejected; oversize rejected; non-image rejected by magic bytes; atomic unique naming; rate limit; existing read-only tests still pass.
Docs: extend docs/bridge-view.md with the upload contract and the inbox location.

Out of scope: any processing of the photos (firstmate reads the inbox itself), push notifications, non-image files.

Delivery is the no-mistakes pipeline through a PR. Do not use --yes. Ask-user findings belong to firstmate, not the implementation worker. Redeploy the live bridge service (launchctl kickstart of the slice-1 service label) only after the PR is green and merged - not at checks-green before merge.

What Changed

Add a phone-first photo picker and authenticated upload endpoint to the bridge view, including success/failure feedback and a daily received count.
Validate image type and magic bytes, enforce a 15 MB cap and per-session rate limit, and atomically publish uniquely named photos with JSON sidecars to the quarantined data/bridge-inbox/ directory.
Document the upload contract and expand bridge tests for authentication, rejection responses, rate limiting, unique naming, atomic cleanup, and existing read-only behavior.

Risk Assessment

✅ Low: The follow-up correctly resolves the atomic image-plus-sidecar publication failure, adds targeted regression coverage, and introduces no new material risks in the reviewed branch diff.

Testing

The complete bridge behavior suite passed, including existing read-only protections and upload authentication, 413/415/429 handling, rate limiting, atomic uniqueness, sidecars, and counts; a manual authenticated HTTP upload then returned success and persisted the expected quarantined pair, while the phone-sized authenticated page was preserved as rendered HTML because the screenshot utility reported a path but did not materialize an image file.

🔧 **Review** - 3 issues found → auto-fixed ✅

🚨 bin/fm-bridge-view.py:355 - Required intent says uploads must “write atomically into data/bridge-inbox/ … with … a sidecar .json.” The changed code publishes the image first (os.link(tmp, dest)) and sidecar second (os.link(tmp_json, side)); if the second link fails with an OSError other than FileExistsError (for example ENOSPC), the published image is left orphaned. Do not merge without deciding how the image/sidecar pair must be exposed atomically or rolled back on every failure.
⚠️ bin/fm-bridge-view.py:1277 - Several early upload rejections return without consuming the declared request body or setting self.close_connection = True (including unauthorized and rate-limited requests). Under HTTP/1.1 the handler can then interpret remaining multipart bytes as another request on the same connection, corrupting keep-alive behavior. Explicitly close the connection for every pre-read rejection, or drain the bounded body before responding.
⚠️ bin/fm-bridge-view.py:1314 - The declared content type is only checked against the allowlist and never compared with the sniffed format. A PNG declared as image/jpeg is accepted, stored with a .png extension, but its sidecar records image/jpeg; downstream inbox consumers therefore receive contradictory metadata. Reject mismatches or record the verified media type.

🔧 Fix: Ensure atomic inbox pair publication, captain

bash tests/fm-bridge-view.test.sh
Started bin/fm-bridge-view.sh serve --host bridge.test.example --port 18766 against an isolated evidence home, authenticated through POST /login, then uploaded a magic-valid JPEG through multipart POST /upload
Inspected the resulting data/bridge-inbox/ image, JSON sidecar, unique timestamped names, directory mode, metadata, and stored bytes
Rendered the authenticated glance_html at a 390×844 mobile viewport and inspected the visible file chooser, Send photo button, result area, and daily count

⚠️ **Document** - 1 error

🚨 bin/fm-bridge-view.py:68 - The endpoint accepts image/heif, but the authoritative intent permits only JPEG, PNG, HEIC, and WebP. Resolving this requires executable and test changes outside this documentation-only task.
