 # Changelog
 All notable changes to The Meme Protocol are documented here. Versions follow Semantic Versioning.
 ## [Unreleased]
 ### Fixed
 - Added `HEAD` support for public pages, discovery documents, assets, meme media, and health checks so social crawlers can validate card resources without receiving false `404` responses.
 - Replaced the 1.6 MB social-preview PNG with a fingerprinted, metadata-stripped 226 KB JPEG for faster and more reliable link-card fetching across social platforms.
 ## [1.1.0] - 2026-08-14
 ### Added
 - One-click image copying from feed cards and the full-image viewer.
 - Copy, download, share, view-count, and download-count controls in the full-image viewer.
 - `DOWNLOAD PET` and `READ LORE` protocol menu actions.
 - Shareable `/lore` viewer backed by a downloadable plain-text lore file.
 - Site-styled pet download chooser offering the original and V2 Homo Reseticus ZIP packages, with a Petdex availability link.
 - Eighteen generated demo memes, including automatic top-up of older demo-only stores, so local scrolling exercises pagination.
 - A 300ms minimum spinner display for subsequent pages, preventing imperceptible flashes on fast local connections.
 - Dedicated `1200x630` social preview metadata for homepage and lore shares, replacing the source repository logo.
 - A complete, cache-versioned favicon suite for browser tabs, bookmarks, Apple Touch icons, and installed web apps.
 ### Changed
 - Fixed the source footer to the viewport bottom and reserved enough scroll space to keep the final images and feed loader unobscured.
 - Expanded meme IDs in the full-image viewer while retaining compact IDs on feed cards.
 - Renamed the user-facing `SUBMIT` / `SUBMIT_MEME` language to `ADD MEME` / `ADD_MEME`.
 - Updated package and OpenAPI versions from `1.0.0` to `1.1.0` for this backwards-compatible feature release.

-# The Meme Protocol
+# bitasforfree
-Small self-hosted meme gallery matching the `stitch_the_meme_protocol` desktop mockup direction.
+Code powering the bitsforfree website
 Current release: `1.1.0`.
 The browser feed supports one-click image copy, downloads, shareable meme links, full-image viewing with live view/download counts, a fixed source footer, a two-build Homo Reseticus pet download chooser, and shareable lore at `/lore`.
 Homepage and lore social shares use the fingerprinted, metadata-stripped `1200x630` JPEG at `/assets/social-preview-v2.78d008df9860.jpg`. Individual meme permalinks continue to use their own meme image.
 Browser tabs, bookmarks, Apple home-screen links, and installed web apps use the supplied favicon suite under `/assets/favicon/`; the legacy `/favicon.ico` URL remains available for automatic browser requests.
 ## Run locally
 ```sh
 npm start
 ```
 The server listens on `http://localhost:8080` by default.
 ## Configuration
 - `PORT`: HTTP port, default `8080`
 - `HOST`: bind address, default `0.0.0.0`
 - `DATA_DIR`: disk storage root, default `./data`
 - `SITE_URL`: public canonical site URL used for SEO metadata, sitemaps, feeds, `llms.txt`, OpenAPI servers, and API skill instructions. Production should use `https://bitsforfree.com`.
 - `SEED_DEMO_MEMES`: set to `false` to disable generated demo memes. When enabled, empty and legacy demo-only stores are filled to 18 samples so local pagination can be tested.
 - `ADMIN_TOKEN`: secret review URL token. If omitted, one is generated at boot and printed in server logs.
 - `OPENAI_API_KEY`: enables AI upload moderation. Without it, uploads are queued for admin review.
 - `OPENAI_MODERATION_MODEL`: moderation vision model, default `gpt-4o-mini`
 - `AUTO_APPROVE_MIN_SCORE`: minimum `MEME_CONSENSUS_SCORE` for immediate AI approval, default `80`
 - `TRUST_PROXY`: set to `true` when running behind a trusted reverse proxy so upload limits use `X-Forwarded-For`
 Uploads accept PNG and JPEG images. The server rejects files over 5 MB, any image edge over `6000px`, and images over 20 million pixels. Accepted uploads are decoded, metadata-stripped, resized so the longest edge is at most `1600px`, and stored as WebP.
 Upload caps are 5 per hour per IP, 10 per day per IP, and 100 globally per day. Strong AI-approved uploads publish immediately; ambiguous or low-quality uploads are queued for the secret admin review page; likely illegal uploads are rejected immediately.
 Files are stored under sharded date/hash paths:
 ```text
 data/
  index/memes.jsonl
  index/tags.json
  memes/YYYY/MM/DD/aa/bb/<sha256>.<ext>
  meta/YYYY/MM/DD/aa/bb/<sha256>.json
 ```
 ## Discovery Metadata
 The app serves crawler and answer-engine metadata without adding visible page copy:
 - `/openapi.json`
 - `/meme-api.skill.md`
 - `/robots.txt`
 - `/sitemap.xml` with the home page and approved meme URLs
 - `/feed.json`
 - `/llms.txt`
 - `/site.webmanifest`
 - Open Graph, Twitter card, canonical, and JSON-LD metadata on `/`
 Set `SITE_URL` in production so canonical and API discovery URLs use the public domain instead of an internal proxy hostname. The server loads `.env` at startup when present, while real environment variables still take precedence.
 ## Public API
 - `GET /api/memes?page=1&pageSize=12`: lists approved memes with `caption` and `tags`. `pageSize` is capped at `48`. Add `q=angry%20cat` for ranked caption/topic search and `tag=cats` for a topic filter. Repeat `tag` to require all selected topics.
 - `GET /api/tags`: lists the available managed tag names.
 - `GET /api/memes/<sha256>`: returns public metadata for one approved meme.
 - `GET /meme/<sha256>`: opens an approved meme in the viewer and provides its shareable permalink.
 - `GET /media/<sha256>`: returns the normalized WebP image for one approved meme.
 - `POST /api/memes`: adds one PNG/JPEG upload as `multipart/form-data` with a file field named `meme`.
 API uploads use the exact same path as the browser form: persistent IP upload quotas, file size checks, image dimension and pixel checks, metadata-stripping WebP normalization, AI moderation, and admin-review queueing. A published upload returns `201`; a queued upload returns `202` with `moderationReason`; moderation rejection returns `422` with `moderationReason`.
 Public API reads are rate-limited per IP and return `429` with `Retry-After` when exceeded. List and metadata responses include `RateLimit-*` headers and a `rateLimit` object.
 ## Captions, tags, and administration
 The LLM moderation call also writes a factual searchable caption and chooses relevant tags from the admin-managed catalog. The server filters out invented tags. Uploaders cannot supply captions or tags; reads and search are public, while every metadata mutation requires the existing `X-Admin-Token` authentication.
 Search is lexical: case/accent-insensitive words, prefixes, and small spelling corrections, ranked by relevance then newest first. All query words and all selected tags must match. It does not use embeddings or infer semantic synonyms. Limits: 200 query characters, 20 tag filters, 200 managed tags, 60 characters per tag, and 2000 caption characters.
 Open `/admin/<ADMIN_TOKEN>` to manage pending, published, or all images; edit captions and assigned tags; and add or remove topics. Tag names are lowercase and accept letters, numbers, spaces, underscores, and hyphens. Removing a tag clears its assignments from every image.
 Existing records load with empty captions/tags; no offline migration is needed. Define your topics, then use **GENERATE ALL MISSING CAPTIONS** to backfill all existing images. The browser processes images sequentially, saves each result immediately, and can stop after the current image. Re-running resumes missing captions. **GENERATE AI FOR SELECTED** can regenerate metadata for existing captions (for example after adding topics). Generation uses `OPENAI_API_KEY` and `OPENAI_MODERATION_MODEL`, incurs normal model usage, and leaves existing metadata and approval status intact on failure. Manual edits made while an AI request is running are preserved via a version check. Without an API key, uploads remain pending with empty metadata, and admins can still edit manually.
 Authenticated admin endpoints (not part of the public OpenAPI):
 - `GET /api/admin/memes?page=1&pageSize=12&status=all`: paginated image management; `status` accepts `pending`, `approved`, or `all`. Supports `q`, repeated `tag`, and `missingCaption=true`.
 - `PATCH /api/admin/memes/<sha256>` with `{ "caption": "...", "tags": ["cats"] }`: edit either or both metadata fields; unknown tags are rejected.
 - `POST /api/admin/memes/<sha256>/generate`: generate caption and tags without re-moderating; optional `{ "onlyMissing": true }` skips already-captioned images.
 - `GET /api/admin/tags`, `POST /api/admin/tags` with `{ "name": "cats" }`, and `DELETE /api/admin/tags/<URL-encoded-name>`: manage the catalog.
 Admin responses use `Cache-Control: no-store`. Unauthenticated admin API requests return `404`.
 ## Docker
 ```sh
 docker build -t meme-protocol .
 docker run --rm -p 8080:8080 -v meme-protocol-data:/data meme-protocol
 ```
 For production, copy `.env.example` to `.env`, set real secrets, then run:
 ```sh
 docker compose up -d --build
 ```
 The included compose file binds the app to `127.0.0.1:18080` on the host so a reverse proxy can publish it without exposing the Node container directly.
 ### Production Build Note
 On the production host used for this project, npm registry downloads from inside Docker timed out unless `registry.npmjs.org` was pinned to a known-good IPv4 address during build. The proven build command is:
 ```sh
 sudo docker build \
  --network=host \
  --add-host registry.npmjs.org:104.16.1.34 \
  -t meme-protocol:latest .
 ```
 Then start with the already-built image:
 ```sh
 sudo docker compose up -d --no-build
 ```
 If the registry IP ever stops working, resolve and test another IPv4 address for `registry.npmjs.org`, then replace `104.16.1.34` in the build command.
 When using a host-mounted data directory, the container writes as UID/GID `10001:10001`:
 ```sh
 sudo mkdir -p ./data
 sudo chown -R 10001:10001 ./data
 sudo chmod -R u+rwX,g+rwX,o-rwx ./data
 ```

 # The Meme Protocol API Skill
 Use this skill when an agent needs to read approved memes from The Meme Protocol or add a meme image through the public upload API.
 ## Discovery
 - OpenAPI: `__API_BASE_URL__/openapi.json`
 - Skill instructions: `__API_BASE_URL__/meme-api.skill.md`
 - Public meme list: `GET __API_BASE_URL__/api/memes`
 - Public tag catalog: `GET __API_BASE_URL__/api/tags`
 - Public meme metadata: `GET __API_BASE_URL__/api/memes/{id}`
 - Public meme image: `GET __API_BASE_URL__/media/{id}`
 - Add meme: `POST __API_BASE_URL__/api/memes`
 ## Read Memes
 Call `GET __API_BASE_URL__/api/memes?page=1&pageSize=12` to list approved memes. `page` starts at `1`; `pageSize` is capped at `48`. The response includes `page`, `pageSize`, `total`, `totalPages`, `memes`, and `rateLimit`.
 Each meme includes `caption` (searchable text, possibly empty for older images) and `tags` (managed topic names).
 Search using `GET __API_BASE_URL__/api/memes?q=angry%20cat&pageSize=12`. Matching ignores case and accents and tolerates prefixes and small typos. Every query word must match a caption or assigned tag. Results are ordered by relevance, then newest first. This is lexical fuzzy search, not semantic search.
 Read `GET __API_BASE_URL__/api/tags` for the available tag catalog, then filter with `GET __API_BASE_URL__/api/memes?tag=cats`. Repeat `tag` to require multiple topics, and combine it with `q`. Queries are limited to 200 characters and 20 tag filters; invalid filters return `400`. Pages beyond the last page are clamped, so use `totalPages` to stop pagination.
 Call `GET __API_BASE_URL__/api/memes/{id}` to retrieve one approved meme by its 64-character lowercase hex SHA-256 ID. Pending, rejected, deleted, or unknown memes return `404`.
 Use each meme's `url` field to fetch the normalized WebP image. Public image URLs are under `__API_BASE_URL__/media/{id}` and may be cached aggressively by clients.
 Read endpoints are rate-limited per IP. Respect `RateLimit-Limit`, `RateLimit-Remaining`, `RateLimit-Reset`, and `Retry-After` headers. Prefer small page sizes and back off on `429`.
 ## Add Memes
 Add a meme with `POST __API_BASE_URL__/api/memes` as `multipart/form-data`. The image file field must be named `meme`. Captions and tags are generated by the server. Public clients cannot create tags or edit image metadata.
 Example:
 ```sh
 curl -F "meme=@example.png" __API_BASE_URL__/api/memes
 ```
 The API intentionally uses the same upload path as the human browser form:
 - Accepts one image per request.
 - Accepts PNG and JPEG only.
 - Rejects empty files and unsupported media types.
 - Rejects files over 5 MB.
 - Rejects images with any edge over 6000 px.
 - Rejects images over 20 megapixels.
 - Normalizes accepted images to metadata-stripped WebP with longest edge at most 1600 px.
 - Runs the same AI moderation workflow.
 - Applies the same per-IP upload limits: 5 per hour, 10 per day, and 100 global uploads per day.
 Successful upload responses:
 - `201` means the meme was approved and published immediately.
 - `202` means the meme was accepted and queued for admin review. The body includes `moderationReason`.
 Rejected or invalid upload responses:
 - `400` for malformed multipart requests, missing image field, multiple images, or invalid dimensions.
 - `411` when upload size is missing.
 - `413` when request, file, dimension, or pixel limits are exceeded.
 - `415` when the image is not PNG or JPEG.
 - `422` when moderation rejects the upload. The body includes `moderationScore` and `moderationReason`.
 - `429` when upload quotas are exhausted.
 Do not attempt to bypass moderation, normalization, or limits. There is no privileged public upload endpoint.
