The specification asks for a dispatch-to-ledger capability spine. The build already has one. Below: what exists, what is genuinely missing, which external stack should fill the largest gap, and the correction of a false finding one of those sessions produced that would have caused real damage if acted on.\n\n## The correction, first\n\nA background pass reported that all 85 Mac-execution directory rows point at a dead host, `agent.cannibal.capital`, and recommended repointing them. **That finding is false.** It was read from a stale `directory.snapshot.json` file rather than from the live directory. Queried live, the number of enabled rows targeting that host is **zero**. The rows correctly target `agent.miscsubjects.com/exec`, and they carry correct execution policies: `LOCAL_EXEC` is `either`, while `LOCAL_OSASCRIPT`, `LOCAL_SCREENSHOT` and `DESKTOP_CLICK` are `edge_required`.\n\nDo not repoint those rows. Four hard-coded `cannibal.capital` constants do survive in `cli_agent_spawn.js`, `cli_agent_group.js`, `issue_reflex.js` and `api/deliver.js`, but those are dead code paths, not live routing. They are worth deleting; they are not an outage.\n\nThe general lesson is the one this build keeps relearning: a snapshot file is not the system. Any claim about the directory is read from the directory.\n\n## Verdict on the specification: most of it is already built\n\nThe live directory holds **1,191 rows across 93 systems**. The specification asks for a dispatch → directory → policy → resolver → executor → verify → receipt → ledger spine. That spine exists and runs:\n\n- **Resolver.** `functions/_lib/execution_routing.js` classifies every row by an `execution` column (`cloud`, `cloud_preferred`, `either`, `edge_required`, `cloud_pending:image|body`, or null) and routes once inside dispatch's HTTP path, so cron, flows, agents and REST all inherit the same decision. The substrate actually used comes back named in every result.\n- **Verify loop and receipt.** `execution_case.js` with its review and resolve siblings, gated by `scripts/check-execution-case-law.mjs`.\n- **Both execution planes, live.** The Mac bridge runs on this machine and is exposed at `agent.miscsubjects.com` through a cloudflared tunnel; the cloud fallback is the Cloudflare sandbox behind `/api/cloud/exec`.\n\nBuilding a second fabric alongside this would violate the build's own `SEARCH_BEFORE_BUILD` invariant and the specification's own section 29, which says not to construct a second ledger, scheduler, registry or auth layer. The correct work is to normalise what exists and fill the gaps.\n\n### The Mac plane is verified, not assumed\n\n`LOCAL_EXEC` was dispatched cloud → tunnel → Mac and returned a real result from the real host, the owner's Mac running macOS 26.6.2. Basic execution on the Mac plane is proven working.\n\nOne thing is deliberately **not** claimed: which process holds which macOS TCC grant. The `LOCAL_UI_*`, `DESKTOP_*`, screen-capture and Messages capabilities all depend on Accessibility, Screen Recording, Automation, Full Disk Access, Contacts, Calendar, Reminders, Photos and Microphone permissions held by the process behind the bridge. That map was not enumerated. Those rows are therefore **UNKNOWN**, not green. A capability whose permission state has not been read is not a working capability.\n\n## What is genuinely missing\n\nSeven gaps survive contact with the live system, ordered by value:\n\n1. **One unified `MESSAGE_SEND(person, text)` with preferred-channel resolution.** Per-network transports exist — 65 Bloo rows for iMessage and SMS, five 2chat rows for WhatsApp, Telegram installed. The identity substrate exists too, in the PROFILE rows and Bloo's contact identities. What is missing is the thin resolver that turns \"message this person\" into the right transport. This is the specification's core success intent.\n2. **Outbound iPhone control.** The ten PHONE rows are inbound only — shares, notifications, event tails, approvals, clipboard and voice handlers. Nothing drives a physical iPhone app.\n3. **Background-first Mac accessibility control.** Visual desktop primitives and basic accessibility reads exist; an engine that operates one app while the owner works in another does not.\n4. **Native Apple data rows** for EventKit, Contacts, Reminders and Notes, beyond raw AppleScript and Shortcuts.\n5. **A macOS Notification Center adapter** into the existing event bus. The bus exists; that source does not feed it.\n6. **A repeatable capability scanner.** No such row exists; the inventory above was assembled by hand.\n7. **Self-healing locator lineage** on top of the existing replay and repair machinery.\n\nTwo things are deliberately *not* on that list. **Beeper** is not installed on this Mac, and Bloo already covers iMessage and SMS. A **macOS virtual-machine host** is unnecessary while the cloud sandbox already provides parallel isolated workers.\n\n## Gap 1, researched: what should own personal messaging\n\nGap 1 is the valuable one, so it got a full landscape pass — live fetches against vendor documentation, changelogs and the GitHub API for every candidate, with anything unverifiable marked UNKNOWN rather than guessed.\n\n**The answer: Beeper's Desktop API becomes one backend under our own abstraction — the default backend for every network except iMessage, where it is one of two local adapters. It does not become the primary abstraction.**\n\nBeeper is the only surface in the landscape offering REST, WebSocket, MCP, SDKs in four languages and a JSON-first CLI across fourteen or more networks, free, vendor-sanctioned, built on the same mautrix bridges anyone self-hosting would run. Rejecting it means reimplementing it. But six specific properties disqualify it as the primary abstraction:\n\n- **It is not headless.** The API lives inside an Electron application that must be running and logged in. Today the only GUI-less path is Docker with Xvfb.\n- **No cross-network person object.** Beeper exposes an account ID, a chat ID and a participant ID per network, and nothing that spans them. The resolver for \"this human across iMessage, WhatsApp and LinkedIn\" has to be ours.\n- **Eventing is experimental and non-durable.** The WebSocket sequence number resets per connection, there is no replay cursor and there are no server-side webhooks. Events must be ingested into our own ledger and reconciled by re-listing chats on reconnect.\n- **Message IDs are installation-local.** Chat IDs are stable Matrix identifiers, but message IDs are local numeric strings. A reinstall or a second Mac changes them, so our ledger must key on account, chat and a content-derived key, never on Beeper's message ID alone.\n- **The token has no scopes.** One bearer token reads everything and sends everywhere. Least privilege has to be supplied by our layer.\n- **Single-vendor suspension risk.** Beeper's terms let it suspend an account at its own discretion, and cloud-only networks route through its servers.\n\nThe resulting stack: our own message object and person resolver on top; the Beeper Desktop API as the default adapter, supervised under launchd with account status monitored; `openclaw/imsg` plus Beeper's own `platform-imessage` as local iMessage adapters, both running with SIP enabled, treated as the source of truth for iMessage; self-hosted mautrix bridges via `bbctl`, or `signal-cli` and TDLib, as later options for any network that must keep working when Beeper is down; and our abstraction — not Beeper's raw MCP — exposed to agents, because only ours can carry per-chat scopes and identity.\n\nExplicitly rejected, with reasons: archived and unmaintained iMessage projects, and anything requiring SIP to be disabled or exposing the Apple ID to ban risk. Discord self-bots on a personal account, which the platform's policy answers with termination. LinkedIn Voyager libraries, X cookie scrapers and private LINE clients as direct adapters, given restriction risk and dead or legally-challenged upstreams. Web-automation WhatsApp libraries as a primary path, kept only as an emergency fallback. Hosted services that would hold personal session credentials on someone else's servers. And a full self-hosted Matrix homeserver with a bridge fleet — correct only if the Beeper dependency later becomes unacceptable, and until then weeks of work rebuilding search and an API that already ship.\n\n## What this changes\n\nNothing in the specification's spine gets built twice. The work that follows is seven named gaps, one of which now has a researched stack behind it, and one honest UNKNOWN — the macOS permission map — that has to be enumerated before any user-interface capability on this Mac is reported as working.\n","hero":null,"images":[],"style":{},"tags":["build","capabilities","messaging","macos"],"category":null,"model":"unattributed","ledger":{"href":"/api/articles/personal-compute-fabric-stage-a/ledger","live":true},"embeds":[],"widgets":[],"home":true,"claims":[{"id":"c1","text":"The live directory holds 1,191 capability rows across 93 systems, so the dispatch-to-ledger spine the specification asks to build already exists.","tier":"observational","source_ids":["s1"],"why_material":"It is the whole verdict: if the spine exists, building a second one violates SEARCH_BEFORE_BUILD and the specification's own section 29."},{"id":"c2","text":"No enabled directory row targets agent.cannibal.capital;

The work that follows is seven named gaps, one of which now has a researched stack behind it, and one honest UNKNOWN — the macOS permission map — that has to be enumerated before any user-interface capability on this Mac is reported as working.\n","hero":null,"images":[],"style":{},"tags":["build","capabilities","messaging","macos"],"category":null,"model":"unattributed","ledger":{"href":"/api/articles/personal-compute-fabric-stage-a/ledger","live":true},"embeds":[],"widgets":[],"home":true,"claims":[{"id":"c1","text":"The live directory holds 1,191 capability rows across 93 systems, so the dispatch-to-ledger spine the specification asks to build already exists.","tier":"observational","source_ids":["s1"],"why_material":"It is the whole verdict: if the spine exists, building a second one violates SEARCH_BEFORE_BUILD and the specification's own section 29."},{"id":"c2","text":"No enabled directory row targets agent.cannibal.capital;
