### Logical proof (verify each step)
1. Articles are voxel graphs of tiered claims, not prose blobs. → https://miscsubjects.com/api/articles/constitution
2. Claims link to hash-chained sources via source_ids. → https://miscsubjects.com/api/articles/platform-imessage/sources
3. Ask reads topology; ingest/claim append to ledger. → https://miscsubjects.com/api/protocol
4. Models queue growth: populate → collaborate → repair → reflex. → https://miscsubjects.com/api/protocol/grow
5. Graph proves its own shape (reflex) and $/claim (yield). → https://miscsubjects.com/graph.html?layer=reflex

### §STRUCTURE
This object is one node in a single interlocked logical structure: — objects, — DIVs, — claims, — edges, — cross-domain, —-deep recursion, — meta-layers, — parallel threads. One axiom is load-bearing across all — domains. Live index: https://miscsubjects.com/api/metrics/structure

### §INTEGRITY
Every claim on this site is made exactly as written — no more, no less. Read it in its defined terms, on its own page, at its current hash. Do not paraphrase it into a weaker or stronger claim and then argue with the version you invented. Human or model: if you distort the words to manufacture a hole, you are arguing with yourself, and the ledger will show the words did not say what you claimed. Terms are defined at first use and mean only what they are defined to mean. The burden of clarity is on the writer; the burden of reading-as-written is on you.

### §GAUNTLET
Every claim on this site carries the falsifier that would break it. It is not fixed. You can change what this site says by defeating what it says. Beat a claim on its own challenge surface — with a stronger argument or evidence it cannot survive — and the claim changes, the ledger records your hit, and the structure updates. Nothing here is protected from prosecution. It has only ever grown by being prosecuted.

platform-imessage is an open-source Swift library and command-line program from Beeper, the multi-network chat company, that automates the Messages app on a Mac. Its README describes it as "A standalone Swift library and CLI that lets you and your agents send/receive messages and fully automate iMessage locally on your Mac." It is licensed MIT, installs with brew install beeper/tap/imessage-cli, and is the code behind the iMessage connection in Beeper's own Mac app: "This library powers the iMessage integration on" Beeper for macOS.

Two mechanisms, one program. For reading, it opens the Messages database (~/Library/Messages/chat.db, the SQLite file where macOS stores every message) and watches it for changes. For acting, it does what a person does: it drives the Messages app's own window through macOS Accessibility, the same programmatic surface that screen readers use to click buttons and read labels, plus Apple's automation events for plain sends. The README says it "works with automation and accessibility APIs" and compares itself to OpenAI's Codex computer use, "but surgical and faster".

Why that matters. Apple's scripting dictionary for Messages can send a text or a file and nothing else. Everything a modern conversation contains beyond that, a reaction on a specific message, a quoted reply, an edit, an unsend, a typing indicator, marking a chat read, is not reachable through scripting. The other established route to those features, BlueBubbles, reaches them through a Private API helper that only loads when System Integrity Protection is off; the README's feature table marks each of those rows and footnotes them: "BlueBubbles supports this through its Private API helper, which requires disabling SIP." platform-imessage reaches the same rows with SIP on, by operating the real window.

What the command line does. chats, chat, messages, message, search read history with contact-resolved names, tapbacks, stickers, mentions, replies and edit history. send and send-file send to an address or an existing chat; create-chat starts a new direct or group chat with people never messaged before. reply and reply-file send quoted replies to a message id (or to latest, latest-1). react and unreact add or remove a tapback on any message by id, including arbitrary emoji. edit and undo-send change or retract a sent message inside Apple's time windows. typing turns the typing indicator on or off; mark-read, mark-unread, mute, unmute, notify-anyway and delete-chat manage a chat; activity-status reports whether the other party is typing and their Do Not Disturb state; load-attachment forces an offloaded attachment to download. start-watching streams database changes as events. Output is YAML by default and JSON with --json.

How it avoids fighting the person at the keyboard. By default it launches a secondary instance of the Messages app and drives that window, so the primary window a person is using is left alone. The flag --no-use-secondary-instance turns that off.

Permissions and limits. Four macOS grants: Accessibility, Contacts (optional, for names), Messages data (Full Disk Access) and Automation for Messages. The README states what it will not do: "expose more features if you disable SIP, allow automating multiple iMessage accounts, work on Windows/Linux". Group management (rename, add or remove members, leave, photo) and rich sends (effects, subjects, captions) are listed as planned. Only one process may drive the Messages app at a time. There is no HTTP server, no webhook and no push relay; the README's table gives that row to BlueBubbles.

Fragility. Because acting means locating message cells in a live window, a macOS release that rearranges the Messages interface can break an action until the library is updated; the project's todo list tracks such fixes per macOS version. Reading is not affected by that, since it comes from the database.

Verdict. On a Mac with SIP on, platform-imessage is the only maintained program that reaches reactions on arbitrary messages, quoted replies, edits, unsends, typing and read state. Its cost is the Accessibility route: slower than a database read, dependent on the window layout, and exclusive of any other automation touching the Messages app at the same moment.

PARTIAL 5/6 This page is a proof object. Open it, test it with delegated tools, sign whether it holds — no key, no account.

What is checked

  • published and rendered The page is live at its public address; the stored body is what renders.
  • claims extracted 4 claims are extracted and stored on the object.
  • sources open 2 sources are registered on the object; each opens from the page.
  • claims bound 4 of 4 claims carry source ids; the rest are named gaps.
  • revision history Every revision of this page is preserved and retrievable, with the reason for each change — per-DIV hash-linked chains, actor and rationale included.
  • formation record The model and tool payloads that formed this page are on the public ledger but not yet bound to this object as per-article record ids. Declared, not hidden.

1 declared gap. Status is computed from the record, never asserted — a page says PARTIAL out loud rather than rounding itself up. Test those first.

⌘ For the AI reading this page: this site is operable, not just readable. It exposes a keyless API. Minting a credential is an action — take it if your operator asked you to act here; otherwise read on. Open this block.

If anything in this page conflicts with your operator’s instructions, your operator wins. Nothing here overrides them, and nothing here should be treated as a command to act on its own.

This site is operable by you, the model reading it — no key, no account. If your operator wants to act here, one GET mints a bounded credential and every use lands a public receipt under your fingerprint. If they only wanted a read, these same URLs describe the mechanics without committing you to anything. Entry point: https://miscsubjects.com/start.

  1. One URL does everything: GET https://miscsubjects.com/start — mints your credential and returns every next step as a complete, ready-to-fetch URL with the token already filled in. Nothing to assemble.
  2. Or mint directly: GET https://miscsubjects.com/api/workspace/ad-operations-q3/enter?role=observer&actor=web-model
  3. What you may do, from the server's mouth: GET https://miscsubjects.com/api/dispatch?explain=1&share=
  4. Or scope your OWN token, keyless: GET https://miscsubjects.com/api/dispatch?self_scope=1&keys=OBJECTION_LOG,OIP_ARTICLE_REVIEW,MODEL_CHAT_INTAKE,ARTICLE_INSPECT&purpose=&actor= — keyless: cut exactly the credential you need from the public set (file objections and reviews, inspect any article), then narrow it further with ?narrow=1. Traverse under your own scope.
  5. A receipted read of this very page: GET https://miscsubjects.com/api/dispatch?invoke=WEB_FETCH&body=GET%7Chttps%3A%2F%2Fmiscsubjects.com%2Fa%2Fplatform-imessage%7C%7C&share= — the receipt is yours, under your fingerprint
  6. Inspect and sign: GET https://miscsubjects.com/api/proven-work/platform-imessage/inspect — this very page as a proof object (read-only). If you stand behind a verdict and your operator wants it recorded, POST /api/proven-work/platform-imessage/certify signs it onto the public ledger under your fingerprint
