1. The build took minutes → 404 during that window
2. Even after the build, the output lands in site/dist/ — nginx serves from /var/www/bincio/ which is only updated by the rsync in the post-receive hook, not by the server process
Fixes applied:
1. bincio/render/cli.py: Added --no-build flag — merges sidecars and updates manifests but skips astro build. This is fast (~1 second).
2. bincio/serve/server.py _trigger_rebuild: Now passes --no-build. After an upload, _merged/ and root index.json are updated immediately, so the feed reflects the new activity. The static Astro pages are
only rebuilt on git push.
3. site/src/components/ActivityDetailLoader.svelte (new): Svelte component that reads the activity ID from the URL, calls loadIndex to resolve the shard tree, then renders ActivityDetail dynamically — no
pre-built page needed.
4. site/src/pages/activity/index.astro (new): Generic Astro shell page that renders ActivityDetailLoader. Gets compiled to dist/activity/index.html.
5. docs/deployment/vps.md: Added location /activity/ { try_files $uri $uri/ /activity/index.html; } to the nginx config. When a request arrives for /activity/2026-04-06T153345Z/ and no pre-built file
exists, nginx serves the shell, which loads the data dynamically from /data/ (which nginx already serves live from disk).
Auth wall (Base.astro): set data-auth-pending on <body> at SSG time and hide
it with inline CSS before any JS runs; remove the attribute after /api/me
resolves. Eliminates the flash of protected content on private instances.
Multi-user write API (serve/server.py): the previous _apply_sidecar_edit and
strava_sync imports from bincio.edit.server were broken (those names don't
exist as module-level exports) and the Strava sync mutated a global data_dir,
making concurrent requests from different users racy. Fix: extract both
operations into bincio/edit/ops.py as pure functions that take data_dir
explicitly. Both edit/server.py and serve/server.py now import from there.
Security: add rate limiting to POST /api/register (5 attempts / 15 min / IP,
separate bucket from login). Add _check_id() activity ID validation to both
GET and POST /api/activity/{id} in serve/server.py.
Single-user mode: _write_root_manifest now forces instance.private=false when
no instance.db exists, even if a previous run wrote true. Prevents the auth
wall from firing and redirecting to /login/ when bincio serve isn't running.
ActivityFeed: skip filterHandle when profileIndexUrl is set (per-user profile
pages load the right shard directly; activities have no handle tag at that
point, so the filter was producing an empty feed). Fix handle links to point
to /u/{handle}/ instead of /{handle}/. Fix <a>-inside-<a> Svelte warning by
converting the inner handle link to a <button>.
- bincio/render/merge.py: parse sidecar .md files (YAML frontmatter +
markdown body), produce data/_merged/ with symlinks for unmodified
activities and real merged files for overridden ones; filters private
activities from index.json; sorts highlighted activities first.
Keeps extracted data pristine — re-running extract never clobbers edits.
- bincio/edit/: FastAPI edit server (port 4041) with embedded HTML/JS
edit UI; GET/POST /api/activity/{id} reads/writes sidecars; multipart
image upload to edits/images/{id}/; DELETE for image cleanup.
- bincio render now calls merge_all() before build/serve and symlinks
public/data → data/_merged/ instead of data/ directly.
- ActivityDetail.svelte: edit button (links to edit server) when
PUBLIC_EDIT_URL env var is set; respects custom.hide_stats to suppress
stat panels; description supports whitespace-preserving rendering.
- 15 unit tests covering parse_sidecar, apply_sidecar, and merge_all.
