Docker Build and Publish / build-and-push (push) Failing after 10s
The service worker precaches index.html together with its response headers, so
a server-only change never reaches an installed client: the client build is
byte-identical, the precache manifest is unchanged, and the worker has no
reason to update. That is why the CSP fix in 1.6.1 did not reach a browser that
already had the app cached — it kept replaying a cached shell carrying the old,
broken CSP, indefinitely.
The release version is now compiled into the client, which makes every release
change the bundle hash, hence index.html, hence its precache revision, hence
sw.js itself — the bytes browsers compare to decide whether to update. Verified
by bumping only the version: index-DYufL2Fa.js -> index-60N_3d5j.js, with the
new name carried into the sw.js manifest.
It also surfaces in the footer, so the deployed version is visible without
digging through devtools.

Docker Build and Publish / build-and-push (push) Failing after 10s
Instaloader metadata was silently lost
Every .json.xz failed with "Failed to fetch" during a scan, though the same URL
fetched fine on its own. RemoteArchiveFile.stream() started a fetch, piped the
body into a TransformStream and returned the readable immediately — nothing
caught a fetch rejection, and the decompressor stops reading at the end of the
xz member, so the response body was never drained or cancelled. Across ~190
sidecars that exhausted the connection pool.
Everything Instaloader archives carry lives in those files, so the failure was
invisible but total. rivvsofficial reported 188 posts, no stories, 0 followers
and a placeholder bio; it now reports 68 posts, 120 stories, 10,337 followers
and the real name, bio and link — 68 + 120 = 188, matching the sidecars exactly
(106 GraphStoryVideo + 14 GraphStoryImage = 120).
These sidecars are a few KB, so they are now read into memory before
decompressing. stream() was left unused by that change and is removed from the
interface and both implementations rather than kept as a trap.
Arrow keys page the carousel
They moved between posts, which contradicted the arrows drawn on the carousel
itself. Arrows now page slides; , and . move between posts, alongside the side
buttons.
Backdrop cross-fade
AnimatePresence had no exit variant, so the outgoing scan backdrop was removed
instantly while its replacement faded in over 1.5s, exposing the pale page
behind it as a white flash. Layers now stack: the outgoing image holds full
opacity until covered, and the 0.4 moved onto the group so overlapping layers
don't darken as they cross. Measured over a real scan: 152 cross-fades with a
layer always opaque, except the opening fade-in where nothing is underneath.

Security
- Fix path traversal in GET /api/archives/:name/files. Express decodes route
params after segment matching, so `..%2f..%2fetc` escaped ARCHIVES_DIR and
returned a recursive listing of arbitrary directories.
- Add CSP and baseline security headers; disable x-powered-by.
- Stop baking GEMINI_API_KEY into the client bundle (the SDK was unused).
- Run the container as `node` instead of root.
Performance
- Add a directory-mtime-keyed archive index, warmed in the background and
persisted. Listing 110k files went from ~52s to ~0.1s; the largest archive
(24k files) serves in ~0.3s. Per-file stat over CIFS costs ~1.4ms and does
not parallelise, so it is now done once rather than per request.
- Build media URLs from the File directly instead of
`new Blob([await file.arrayBuffer()])`, which read every media file fully
into memory (a 20GB archive tried to become 20GB of resident blobs).
- Track and revoke object URLs; previously none were ever revoked.
- Give `requestThumbnail` a stable identity so a completed thumbnail stops
re-running the effect in every mounted thumbnail.
- Namespace IndexedDB keys so listing archives no longer deserializes every
cached thumbnail blob, and thumbnails no longer collide across archives.
- Serve real file sizes: RemoteArchiveFile was constructed with size 0, which
silently disabled high-res thumbnailing for every server archive.
Correctness
- Local archives cached media as blob: URLs, which die with the document, so
a cached local archive restored as an archive of broken images. Media now
carries a stable path and is rehydrated from a persisted directory handle
(File System Access API), falling back to re-prompting for the folder.
- Fix permalinks: the URL-writing effect erased ?a= on mount before the
archive list arrived to consume it, so deep links never resolved.
- Make cache invalidation detect nested changes via a directory signature.
- Add an error boundary and tolerate unparseable dates, which previously
threw a RangeError and blanked the app.
- Default video to muted so autoplay is not blocked by Safari/Firefox.
Features
- Fold sidecar directories into their base profile: `<user> - reels`,
`story - <user>` and `story highlights - <user> - <title>` now appear as
reels, the story ring and Instagram-style highlight circles rather than as
separate archives.
Housekeeping
- Add @types/react; React was previously type-checked against its JavaScript
source, so `npm run lint` gave almost no type safety on components.
- Vendor fonts and PWA icons locally; the app made third-party CDN requests
despite advertising offline support and local-only processing.
- Drop unused better-sqlite3 (a native module that broke `npm install`).
- Add vitest with 36 tests over the filename and directory-naming rules.

Key changes:
- Added Web Worker for background image thumbnailing with a 1MiB threshold to optimize CPU/memory usage.
- Implemented a serial task queue for memory-safe high-res image processing, preventing OOM crashes.
- Added inter-post preloading in the modal for seamless 'Previous/Next' navigation.
- Refined scanning UI with double-buffering and a dark background to completely eliminate white flashes.
- Renamed project to 'instaarchive-viewer' in package.json.
- Fixed 'Open image in new tab' by denylisting /archives and /api in PWA config.
Summary of changes:
- Extracted archive scanning logic into a modular 'useArchiveScanner' hook for better maintainability and performance.
- Refined PostModal carousel with intelligent media preloading and smoother, jitter-free transitions.
- Optimized image rendering with 'decoding=async' and removed 'black flashes' between slide changes.
- Updated PWA configuration to 'autoUpdate' with hourly periodic checks for fresh content.
- Fixed several bugs including stories sorting, permalink parameter cleanup, and profile metadata cache restoration.
- Comprehensive updates to documentation (README.md and GEMINI.md) reflecting the new architecture.
