feat(intake): a wall on the way in, and the portal spine beside it

22,487 journalled signals held 2,255 distinct things. One typewriter post
arrived 168 times, and a run of dev.to posts sold aged Gmail accounts. Asking
an honest question returned the loudest thing rather than the truest one,
because arrival was the only thing being counted.

Intake refuses three facts anyone can check — already here, nothing said,
selling — and names which one. A duplicate still touches the copy already held,
because a feed re-sending its front page is alive and refusing it silently
would make the frequency read as dead. The fingerprint rides on the signal, or
a registry keeps refusing content it no longer holds. Filler can no longer
learn a trail: a trail is permanent and was read back with no threshold, so one
lucky score for "also" answered for "also" forever.

The portal spine rides along inert — nothing imports it yet. orgs, portal,
polymesh and outreach are additive, and signalmesh_api is untouched, so this
deploy changes exactly one live path: what is allowed onto the air.

+"""core/intake.py — what is allowed onto the air.
+
+The mesh was never failing to match. It was faithfully carrying whatever it was
+handed, and it had been handed a great deal of nothing: 22,487 journalled
+signals holding 2,255 distinct things, one typewriter post repeated 168 times,
+and a run of dev.to posts about buying aged Gmail accounts. A reader asking an
+honest question got the loudest thing rather than the truest one, because
+frequency of arrival is not evidence of worth and nothing here was measuring
+the difference.
+
+So this is the intake wall, and it takes the same shape as `may_contact` and
+`portal.act`: one place, no way around it, refuses rather than repairs. Three
+reasons a signal is turned away.
+
+    already here   the same content on the same frequency
+    nothing said   a payload with no content in it
+    selling        the account-farm spam that rides public dev feeds
+
+It is deliberately narrow. A quality score would be a filter someone has to
+trust; these are three facts anyone can check, and each refusal says which one
+it was. R4's rule again: report, never silently rewrite — a signal that was
+quietly cleaned up is a signal nobody knows was wrong.
+
+The one thing it does not do is judge whether content is *true*. A feed is an
+untrusted input channel, and text arriving from one is written by strangers who
+know a model may read it. That is what `trusted=False` is for — `polymesh`
+marks what neighbours hand over for exactly the same reason.

+core/matrix.py — the seventy-two are already on the grid. This is what they know.
+
+`agents/matrix_agents.json` has been the grid's own census since spatial_grid.py
+first read it: seventy-two specialists, one per node, nine rows of eight. Every
+`/ui/grid` cell that lights up lights up under somebody's name. But the names
+were decoration — the node had an occupant and the occupant never said anything.
+
+This module gives them the seat they were already sitting in.
+
+    THE DIFFERENCE BETWEEN A ROSTER AND A MATRIX
+
+    A roster is a list of who exists. You pick one and you get a persona: a
+    paragraph of costume, which any model can wear without knowing anything it
+    did not already know. That is a prompt library with extra steps.
+
+    A matrix is a list of who exists *somewhere*. Each specialist here has a
+    node, the node has a coordinate, the coordinate is where the mesh files
+    what it hears. So seating a specialist is not a costume change — it is
+    handing a model the persona AND the material that landed at that address.
+    Node 0 is the Backend Architect and node 0 is also where anything tuned to
+    "backend-architect" got filed. Same address. Superpowered means the persona
+    arrives with its post.
+
+    WHY SEATING IS RANKED, NOT CHOSEN
+
+    Nobody names an agent when they ask a question. They describe a problem,
+    and the mesh already knows which coordinates that description lights up.
+    `seat()` scores the ask against what each specialist declares it does and
+    hands back the best few — with the tokens that earned it, so a wrong seat
+    is visible rather than mysterious.
+
+    Zero matches returns nothing at all. A specialist seated at random is worse
+    than no specialist: it is a confident voice with no reason to be that voice,
+    and crew.py's whole bar is that an answer has to come from somewhere.
+
+    WHAT THIS DELIBERATELY DOES NOT DO
+
+    It does not hydrate per specialist. crew.py seats N providers around ONE
+    look at the world because N hydrations for N opinions is the cost this
+    system exists to avoid. A specialist brief rides on top of that shared
+    windscreen; the only thing it adds privately is what is already filed at
+    its own node, which is a local read and costs nothing.

+"""core/outreach.py — a lead exists, something happens, and what happened
+decides what is allowed to happen next.
+
+That sentence is the whole product. Everything else in here is an adapter.
+
+The shape worth defending is the choke point. Every actuator — this SMTP
+sender, the dialer that replaces `_queue_call`, whatever social worker arrives
+later — reaches a person only by going through `may_contact`. There is
+deliberately no second path. The classic automation failure is one system
+politely opening a conversation while another hammers the same person who
+already asked to be left alone, and that failure is only preventable if
+suppression is a wall rather than a courtesy check each adapter remembers to
+make.
+
+Events are the history and the enrollment row is the derived present. A reply
+does not merely get logged: `record_event` stops the sequence, because a
+consequence that has to be noticed by a separate reconciler is a consequence
+that eventually is not noticed at all.
+
+Conditions are a fixed vocabulary, not an expression language. Four predicates
+cover every sequence anyone has actually asked for, and a parser can arrive the
+day a fifth is genuinely needed.

+"""core/polymesh.py — many meshes, one owner, and the doors between them.
+
+The grid holds 72 cells because `_node_idx` maps every frequency onto
+`rows × cols`, and it is full. Widening it would move every place in the world
+to a new node, which is a large price for one more specialist. The cheaper
+answer is that a full mesh is not a mesh that needs to be bigger — it is a mesh
+that needs a neighbour. Clone the Space, get another 72, and address across.
+
+So this module answers three questions and refuses to answer a fourth:
+
+    who am I          identity(), read from the Space that runs us
+    who is kin        peers attested by the poly-mesh owner
+    what crosses      a read-only surface, narrowed by trust
+    ...is what a peer told me true — no. It is what a peer told me.
+
+That last one is the load-bearing part. A contact point between meshes is an
+untrusted input channel wearing a trusted costume: a peer can hand over signals
+whose text is written to be read by a model, and if those arrive indistinguish-
+able from local truth then the neighbour writes our conclusions. So anything
+received keeps `via` on it forever, is never merged into the local registry, and
+can never cause an actuator to fire. Peers exchange what they know. They do not
+exchange authority.
+
+Attestation is a shared secret held by meshes the same person owns, not PKI.
+That is the honest shape of "these are all mine": symmetric, simple, and no
+weaker than the environment it lives in.
