## spt adapter

```text
Adapter registration: what this node can drive/launch.

The node-local registered set (one command for harness and shell adapters). Feeds creation-time
adapter selection, shell discovery, and the self-update ripple.

Usage: spt adapter <COMMAND>

Commands:
  add             Register an adapter from a local path (a dir holding manifest.toml, or the
                  manifest file itself) or from GitHub (--github user/repo, cloned under
                  adapters/_github/). Manifest-first: an invalid manifest registers nothing.
                  Install is the first update — the declared [update] avenue is conducted once
                  after recording
  remove          Soft-deregister: hidden from new-creation/discovery; existing and live instances
                  keep running. The manifest's optional uninstall template is conducted only with
                  --force until quiesce detection lands
  list            List registered adapters (active and soft-deregistered), each followed by its
                  shipped + local profiles as composite options
  create-profile  Create (or overwrite) a local profile — a node-local sparse overlay registered
                  beside the adapter that survives adapter add re-registration. The overlay TOML
                  is read from --from <file> or piped stdin (empty = a placeholder profile to
                  populate later with set-string). Refuses a name shadowing a shipped profile, an
                  invalid name, or an overlay that loosens a consent floor — nothing is written
                  unless every check passes
  delete-profile  Delete a local profile. Refuses a shipped profile name (adapter-owned,
                  immutable) and errors if no local file exists
  get-string      Read a [strings] dot-path from an adapter option's merged view
                  (<adapter>[:profile] <key.path>). Resolves through the profile overlay like
                  every other consumer; prints the value (strings raw, else JSON). Exit 1 if the key
                  is unset. Strings are data — never executed
  digest-proof    Prove an adapter's [digest] extractor against a real log sample (ADR-0019). Runs
                  the declared extractor over --sample <log> (or the declared source) and prints
                  the parsed contract records, the rendered digest, and every dropped line with
                  its reason — the author-time answer to "spt endpoint digest returns nothing"
                  (no silent empty). Exit 1 if any line drops or nothing parses
  set-string      Set a [strings] dot-path on a local profile (<adapter>:<profile>). Sugar
                  over editing the overlay file; refuses a shipped profile and a bare option (a
                  local target is required — create-profile first)
  update          Update registered adapters that ship from their own GitHub releases: compare each
                  [update] avenue = "gh_release" adapter's latest release version against the
                  installed one and, when newer, fetch the release archive, verify it against the
                  declared signing key if any (else trusting HTTPS + GitHub), and re-register. With
                  no name, sweeps every gh_release adapter; with a name, updates just that one
  use             Set or clear the active-profile pointer — the default <adapter>[:profile] a
                  harness session binds to when no --adapter is given. spt adapter use
                  <adapter>[:profile] points every host binary the adapter declares at it (run once
                  per host binary you support); --clear <adapter|binary> drops the pointer
                  (resolution falls back to the freshest-registered adapter). Never changed by
                  install or update
  help            Print this message or the help of the given subcommand(s)

Options:
  -h, --help
          Print help (see a summary with '-h')
```

### spt adapter add

```text
Register an adapter from a local path (a dir holding manifest.toml, or the manifest file itself)
or from GitHub (--github user/repo, cloned under adapters/_github/). Manifest-first: an invalid
manifest registers nothing. Install is the first update — the declared [update] avenue is
conducted once after recording

Usage: spt adapter add [OPTIONS] [PATH]

Arguments:
  [PATH]  Local manifest source (omit when using --github or --release)

Options:
      --github <GITHUB>    GitHub source user/repo — shallow-clone the repo and register the clone
                           root. Manifest-first, then install via the declared [update] avenue
      --release <RELEASE>  GitHub release source user/repo — fetch the adapter archive asset from
                           the release and register it: ships built binaries, source-free and
                           versioned (the pattern for a monorepo whose adapter is a subdir)
      --tag <TAG>          Release tag for --release (default: the latest release)
      --asset <ASSET>      Release asset name for --release (default: adapter.spt — a tar archive
                           whose root holds manifest.toml + strings/ + binaries)
  -h, --help               Print help
```

### spt adapter remove

```text
Soft-deregister: hidden from new-creation/discovery; existing and live instances keep running. The
manifest's optional uninstall template is conducted only with --force until quiesce detection
lands

Usage: spt adapter remove [OPTIONS] <NAME>

Arguments:
  <NAME>  

Options:
      --force  Conduct the manifest uninstall template now, without waiting for quiesce
  -h, --help   Print help
```

### spt adapter list

```text
List registered adapters (active and soft-deregistered), each followed by its shipped + local
profiles as composite options

Usage: spt adapter list

Options:
  -h, --help  Print help
```

### spt adapter create-profile

```text
Create (or overwrite) a local profile — a node-local sparse overlay registered beside the
adapter that survives adapter add re-registration. The overlay TOML is read from --from <file>
or piped stdin (empty = a placeholder profile to populate later with set-string). Refuses a name
shadowing a shipped profile, an invalid name, or an overlay that loosens a consent floor — nothing
is written unless every check passes

Usage: spt adapter create-profile [OPTIONS] <ADAPTER> <NAME>

Arguments:
  <ADAPTER>  The parent adapter (must be registered)
  <NAME>     The local profile name (the :<profile> of the composite address)

Options:
      --from <FROM>  Read the overlay TOML from this file instead of stdin
  -h, --help         Print help
```

### spt adapter delete-profile

```text
Delete a local profile. Refuses a shipped profile name (adapter-owned, immutable) and errors if
no local file exists

Usage: spt adapter delete-profile <ADAPTER> <NAME>

Arguments:
  <ADAPTER>  
  <NAME>     

Options:
  -h, --help  Print help
```

### spt adapter get-string

```text
Read a [strings] dot-path from an adapter option's merged view (<adapter>[:profile] <key.path>).
Resolves through the profile overlay like every other consumer; prints the value (strings raw, else
JSON). Exit 1 if the key is unset. Strings are data — never executed

Usage: spt adapter get-string <OPTION> <KEY>

Arguments:
  <OPTION>  <adapter> or <adapter>:<profile>
  <KEY>     Dot-separated key path into [strings] (e.g. hook.additionalContext)

Options:
  -h, --help  Print help
```

### spt adapter digest-proof

```text
Prove an adapter's [digest] extractor against a real log sample (ADR-0019). Runs the declared
extractor over --sample <log> (or the declared source) and prints the parsed contract records, the
rendered digest, and every dropped line with its reason — the author-time answer to "`spt
endpoint digest` returns nothing" (no silent empty). Exit 1 if any line drops or nothing parses

Usage: spt adapter digest-proof [OPTIONS] <OPTION>

Arguments:
  <OPTION>  <adapter> or <adapter>:<profile> (must declare [digest])

Options:
      --sample <SAMPLE>    A real session-log sample to run the extractor over (recommended)
      --session <SESSION>  The {session_id} to fill into the extractor command (the daemon fills
                           the live one at runtime). Defaults to a placeholder so a
                           {session_id}-templated extractor — the published shape — proofs; pin a
                           real id when the file the extractor locates depends on it
  -h, --help               Print help
```

### spt adapter set-string

```text
Set a [strings] dot-path on a local profile (<adapter>:<profile>). Sugar over editing the
overlay file; refuses a shipped profile and a bare option (a local target is required —
create-profile first)

Usage: spt adapter set-string <OPTION> <KEY> <VALUE>

Arguments:
  <OPTION>  <adapter>:<profile> — the local profile to edit
  <KEY>     Dot-separated key path into [strings]
  <VALUE>   The string value to store

Options:
  -h, --help  Print help
```

### spt adapter update

```text
Update registered adapters that ship from their own GitHub releases: compare each `[update] avenue =
"gh_release"` adapter's latest release version against the installed one and, when newer, fetch the
release archive, verify it against the declared signing key if any (else trusting HTTPS + GitHub),
and re-register. With no name, sweeps every gh_release adapter; with a name, updates just that one

Usage: spt adapter update [NAME]

Arguments:
  [NAME]  A single registered adapter to update (all gh_release adapters if omitted)

Options:
  -h, --help  Print help
```

### spt adapter use

```text
Set or clear the active-profile pointer — the default <adapter>[:profile] a harness session
binds to when no --adapter is given. spt adapter use <adapter>[:profile] points every host
binary the adapter declares at it (run once per host binary you support); --clear <adapter|binary>
drops the pointer (resolution falls back to the freshest-registered adapter). Never changed by
install or update

Usage: spt adapter use [OPTIONS] <TARGET>

Arguments:
  <TARGET>  <adapter>[:profile] to make active — or, with --clear, the <adapter> or host
            <binary> whose pointer to drop

Options:
      --clear  Clear the pointer for target instead of setting it
  -h, --help   Print help
```

## spt daemon

```text
The per-machine daemon: run, stop, or read node status.

Bare spt daemon renders the node status view — daemon state, member subnets, local endpoints (M8
decision 25).

Usage: spt daemon [COMMAND]

Commands:
  run     Run the per-machine daemon in the FOREGROUND — this process IS the daemon, blocking until
          signalled (the service unit's ExecStart, or manual debugging). Never detaches; for a
          background daemon use start
  start   Ensure the daemon is up in the background (idempotent, service-aware): a registered OS
          service is driven via its manager, else a detached daemon is spawned. Non-blocking
  stop    Stop the daemon (service-aware: a managed service is stopped via its manager so it does
          not auto-restart-fight; else a graceful IPC stop)
  status  Node status: daemon state, member subnets, local endpoints (the bare spt daemon view)
  help    Print this message or the help of the given subcommand(s)

Options:
  -h, --help
          Print help (see a summary with '-h')
```

### spt daemon run

```text
Run the per-machine daemon in the FOREGROUND — this process IS the daemon, blocking until signalled
(the service unit's ExecStart, or manual debugging). Never detaches; for a background daemon use
start

Usage: spt daemon run

Options:
  -h, --help  Print help
```

### spt daemon start

```text
Ensure the daemon is up in the background (idempotent, service-aware): a registered OS service is
driven via its manager, else a detached daemon is spawned. Non-blocking

Usage: spt daemon start

Options:
  -h, --help  Print help
```

### spt daemon stop

```text
Stop the daemon (service-aware: a managed service is stopped via its manager so it does not
auto-restart-fight; else a graceful IPC stop)

Usage: spt daemon stop

Options:
  -h, --help  Print help
```

### spt daemon status

```text
Node status: daemon state, member subnets, local endpoints (the bare spt daemon view)

Usage: spt daemon status

Options:
  -h, --help  Print help
```

## spt grant

```text
Consent grant store: gated capabilities held on this node.

Default-deny (the access whitelist's opposite polarity). An ungranted ask escalates interactively;
add is the durable allow-always answer.

Usage: spt grant <COMMAND>

Commands:
  add     Record a grant: agent may exercise capability on this node. Refuses the reserved
          deferred capability ids (remote-exec, instantiate-anywhere) — their gate refuses
          unconditionally, so a row would only be a footgun-in-waiting
  revoke  Remove the exact grant row. Never widens or narrows neighbours: only the named
          (capability, agent, qualifier) tuple goes
  list    List grant rows (all, or one agent's)
  help    Print this message or the help of the given subcommand(s)

Options:
  -h, --help
          Print help (see a summary with '-h')
```

### spt grant add

```text
Record a grant: agent may exercise capability on this node. Refuses the reserved deferred
capability ids (remote-exec, instantiate-anywhere) — their gate refuses unconditionally, so a row
would only be a footgun-in-waiting

Usage: spt grant add [OPTIONS] <CAPABILITY> <AGENT>

Arguments:
  <CAPABILITY>  The gated capability id (e.g. spawn-shell, owner-shutdown)
  <AGENT>       The subject agent (endpoint id)

Options:
      --qualifier <QUALIFIER>  Narrower target within the node (e.g. the shell-adapter name for
                               spawn-shell). Omitted = the node-wide row; the two never match each
                               other
  -h, --help                   Print help
```

### spt grant revoke

```text
Remove the exact grant row. Never widens or narrows neighbours: only the named (capability, agent,
qualifier) tuple goes

Usage: spt grant revoke [OPTIONS] <CAPABILITY> <AGENT>

Arguments:
  <CAPABILITY>  
  <AGENT>       

Options:
      --qualifier <QUALIFIER>  
  -h, --help                   Print help
```

### spt grant list

```text
List grant rows (all, or one agent's)

Usage: spt grant list [AGENT]

Arguments:
  [AGENT]  

Options:
  -h, --help  Print help
```

## spt notif

```text
Inspect and acknowledge notifications.

Dismissal is the explicit ack — it latches and replicates subnet-wide.

Usage: spt notif <COMMAND>

Commands:
  list     List notifications (all member subnets, or one)
  dismiss  Dismiss (ack) a notification by id — latches, replicates subnet-wide
  help     Print this message or the help of the given subcommand(s)

Options:
  -h, --help
          Print help (see a summary with '-h')
```

### spt notif list

```text
List notifications (all member subnets, or one)

Usage: spt notif list [OPTIONS]

Options:
      --subnet <SUBNET>  Limit to one subnet
  -h, --help             Print help
```

### spt notif dismiss

```text
Dismiss (ack) a notification by id — latches, replicates subnet-wide

Usage: spt notif dismiss <NOTIF_ID>

Arguments:
  <NOTIF_ID>  The notif id (as shown by spt notif list)

Options:
  -h, --help  Print help
```

## spt rc

```text
Attach a local terminal to a broker-held endpoint PTY.

Connects to an spt-hosted session and drives it as a terminal. Local is the degenerate single-node
case of the cross-node attach (one pump, loopback peer). Detach with the ctrl-b prefix then d
(ctrl-b ctrl-b sends a literal ctrl-b); detaching leaves the session running on the broker.
--view watches read-only.

Usage: spt rc [OPTIONS] <ID>

Arguments:
  <ID>
          The endpoint id whose broker-held session to attach

Options:
      --view
          Read-only: render output, forward no input

      --take
          Take control: kick the current controller (a loud notice to them) and drive (REQ-KICK-1).
          Use on an endpoint another node controls

  -h, --help
          Print help (see a summary with '-h')
```

## spt subnet

```text
Subnet membership: status, create, show-code.

A subnet is a private group of paired machines — your agents reach each other across every member
node. Bare spt subnet shows the membership status view.

Usage: spt subnet [COMMAND]

Commands:
  status     Show subnet membership: name, paired nodes, endpoints
  create     Mint a fresh subnet and print its joining material
  show-code  Show a subnet's current 6-digit pairing code (+ URI and QR)
  join       Pair this machine into an existing subnet (guided)
  leave      Exit a subnet: drop its membership and trust material from this node
  prune      Remove a dead node identity's trust rows (and registry rows)
  revoke     Revoke node(s) fleet-wide and rotate the subnet seed
  detach     Stop serving a held subnet (the daemon keeps running)
  attach     Resume serving a detached subnet
  notify     Issue a subnet-wide user notification
  help       Print this message or the help of the given subcommand(s)

Options:
  -h, --help
          Print help (see a summary with '-h')
```

### spt subnet status

```text
Show subnet membership: name, paired nodes, endpoints.

Never prints seeds, epochs, or pairing codes. Bare spt subnet is the same view.

Usage: spt subnet status [OPTIONS] [NAME]

Arguments:
  [NAME]
          Limit to one subnet (all member subnets otherwise)

Options:
      --nodes
          Per-node rows: label, online/offline, [online endpoints/total]

  -h, --help
          Print help (see a summary with '-h')
```

### spt subnet create

```text
Mint a fresh subnet and print its joining material.

This node becomes the sole seed-holder. Prints the current 6-digit code, the otpauth://
provisioning URI, and a terminal QR of it. Gated behind OS elevation (the seed-reveal path).

Usage: spt subnet create <NAME>

Arguments:
  <NAME>
          The new subnet's name

Options:
  -h, --help
          Print help (see a summary with '-h')
```

### spt subnet show-code

```text
Show a subnet's current 6-digit pairing code (+ URI and QR).

The re-provisioning surface: prints the same joining material as create — current code,
otpauth:// URI, terminal QR, expiry. Gated behind OS elevation (or read the code from your
authenticator app). With no name the node's sole subnet is used; if it holds several, the name is
required (never guessed).

Usage: spt subnet show-code [NAME]

Arguments:
  [NAME]
          Which subnet's code to show. Required only when the node holds several

Options:
  -h, --help
          Print help (see a summary with '-h')
```

### spt subnet join

```text
Pair this machine into an existing subnet (guided).

Finds a member machine over LAN + relay rendezvous and runs the code-authenticated pairing ceremony
against it. Prompts for the name and code when omitted (interactive terminals). Gated behind OS
elevation — joining enrolls this whole machine.

Usage: spt subnet join [OPTIONS] [NAME]

Arguments:
  [NAME]
          The subnet to join (as named on the member machine)

Options:
      --code <CODE>
          The current 6-digit code (spt subnet show-code on a member machine, or your
          authenticator app)

  -h, --help
          Print help (see a summary with '-h')
```

### spt subnet leave

```text
Exit a subnet: drop its membership and trust material from this node.

Removes the subnet's seed, its trust rows, its serve-state, and its registry snapshot here. Gated
behind OS elevation (membership exit destroys trust material). The remaining members still hold the
old seed — rotate it there if this machine should not rejoin.

Usage: spt subnet leave <NAME>

Arguments:
  <NAME>
          The held subnet to leave

Options:
  -h, --help
          Print help (see a summary with '-h')
```

### spt subnet prune

```text
Remove a dead node identity's trust rows (and registry rows).

The cleanup verb for a machine that re-paired under a new identity or is gone for good: its stale
trust rows cost a dial every pump tick. Takes a full pubkey hex, an unambiguous prefix, or a node
label. Gated behind OS elevation (trust mutation).

Usage: spt subnet prune <NODE>

Arguments:
  <NODE>
          The dead identity: pubkey hex, unambiguous prefix, or label

Options:
  -h, --help
          Print help (see a summary with '-h')
```

### spt subnet revoke

```text
Revoke node(s) fleet-wide and rotate the subnet seed.

The real revocation (vs prune's local cleanup): writes a PROPAGATING roster tombstone now — so
every member drops the node within a roster round — then schedules one seed rotation at the close of
a coalescing window (default 1h); further revokes in the window join the same rotation (one epoch
bump). Benign offliners auto-heal across the rotation (re-seed grace); the revoked node is locked
out and must re-pair. Each target is a pubkey hex, an unambiguous prefix, or a label. Gated behind
OS elevation.

Usage: spt subnet revoke [OPTIONS] <NODES>...

Arguments:
  <NODES>...
          The identities to revoke: pubkey hex, unambiguous prefix, or label

Options:
      --force-rotate-seed
          Rotate the seed immediately instead of at the window's close — the compromised-node path
          (a benign offliner may then fall behind and must re-pair rather than re-seed)

  -h, --help
          Print help (see a summary with '-h')
```

### spt subnet detach

```text
Stop serving a held subnet (the daemon keeps running).

The membership (seed) stays on disk, but this node neither advertises into nor connects to the
subnet — pairing responder, rendezvous meet, and registry gossip all skip it. Takes effect within
one pump cadence; spt subnet attach reverses it.

Usage: spt subnet detach [OPTIONS] <NAME>

Arguments:
  <NAME>
          The held subnet to stop serving

Options:
      --save
          Also persist as the startup default (survives daemon restarts)

  -h, --help
          Print help (see a summary with '-h')
```

### spt subnet attach

```text
Resume serving a detached subnet.

Advertising + connecting restart within one pump cadence.

Usage: spt subnet attach [OPTIONS] <NAME>

Arguments:
  <NAME>
          The held subnet to serve again

Options:
      --save
          Also persist as the startup default (survives daemon restarts)

  -h, --help
          Print help (see a summary with '-h')
```

### spt subnet notify

```text
Issue a subnet-wide user notification.

Produced into the replicated notification spool and first-fired at the user's most-recently-active
endpoint in that subnet. Body from the trailing arg, or stdin when omitted. Targets the calling
endpoint's HOME subnet unless --target names another (M8 decision 25: no resolvable home + no
--target = refuse).

Usage: spt subnet notify [OPTIONS] [BODY]

Arguments:
  [BODY]
          Notification body (read from stdin when omitted)

Options:
      --target <TARGET>
          Target subnet (defaults to the calling endpoint's home subnet)

      --from <FROM>
          Issuer endpoint id (auto-detected from session if omitted)

  -h, --help
          Print help (see a summary with '-h')
```

## spt update

```text
Self-update operations.

apply is the explicit ack named by the update-consent notification; it re-verifies the staged
release before touching the live daemon.

Usage: spt update <COMMAND>

Commands:
  apply  Apply the staged, verified self-update now
  fetch  Fetch the latest signed release from the GitHub origin and stage it (then spt update
         apply). Bootstraps a node with no peer to pull from
  help   Print this message or the help of the given subcommand(s)

Options:
  -h, --help
          Print help (see a summary with '-h')
```

### spt update apply

```text
Apply the staged, verified self-update now

Usage: spt update apply

Options:
  -h, --help  Print help
```

### spt update fetch

```text
Fetch the latest signed release from the GitHub origin and stage it (then spt update apply).
Bootstraps a node with no peer to pull from

Usage: spt update fetch [OPTIONS]

Options:
      --channel <CHANNEL>  Accept a release on this channel instead of the node's pin (e.g. beta).
                           Default: the node's pinned channel
      --tag <TAG>          Fetch a specific release tag (e.g. v0.3.1) instead of the latest
  -h, --help               Print help
```

## spt api

```text
Harness-contract inbound surface (hook entry points).

The entry points a harness's hooks fire to keep spt-core's on-disk state in sync.

Usage: spt api [OPTIONS] <COMMAND>

Commands:
  seed            Harness-hosted startup: record an ephemeral seed keyed by parent pid
  listen          Consume a seed and hold the perch + relay loop (blocks)
  bind            Post-spawn bind of a session to its perch
  bind-shell      Shell-binary bind: the type=Shell flavor of bind. Resolves the instance by
                  link token alone (the spawn template carries only {link_token} — "owner from
                  the link") and flips it online. The credential IS the auth: no token, no bind
  state           Set activity state busy|idle (also arms the echo-gate sentinel)
  echo-gate       Manage the echo-gate sentinel directly
  poll            Drain delivered messages (hook channel). With --link this is the shell-flavored
                  relay drain: the link token is the auth, and the drained rows are the shell's
                  MAC-stamped command/text/file frames
  worker-start    Create a nested worker perch under a parent
  worker-stop     Tear down a worker perch
  worker-poll     Drain a worker perch's messages
  boundary        Rebind the perch to a new session_id, preserving identity (a context clear/compact
                  boundary)
  session-end     Soft teardown (spool/history preserved); --erase hard-wipes
  presence        Report user/agent presence at this endpoint
  driven-by       Report which node (if any) is remote-driving this endpoint
  history-log     Append normalized history (body on stdin) to the native history store
  digest-entry    Push one digest-record (the published contract JSON line, on stdin) for a log-less
                  adapter — appended to the perch's digest store, tailed by the session-digest
                  projection (ADR-0008 amendment, REQ-TERM-4)
  emit            Emit a Shell sensory payload to the owner's live session. REST-only by
                  definition: never spooled, dropped with a diagnostic when the owner isn't live.
                  The link token is the auth
  drive-poll      Take-and-clear a Shell's pending drive frame: the shell-side drain of the
                  owner→shell ephemeral control channel. REST-only, exactly-once — the daemon serves
                  the single latest frame and ONLY when the link matches the slot's write-time stamp
                  (no stale-control replay on relink). The link token is the auth (mirrors emit).
                  The frame, if any, prints to stdout
  tunnel          Use the shell end of the opaque byte TUNNEL: a held, reliable-ordered QUIC stream
                  the channel taxonomy never reinterprets (first consumer: USB/IP URB traffic).
                  send pipes raw stdin into the tunnel; recv drains buffered bytes to raw
                  stdout. The link token is the auth (mirrors drive-poll); the stream resolves
                  only under the live link generation. Poll-drained at the surface
  capability      Print the adapter's declared capability (hostable_types)
  hint            Keyword hints: the full user message arrives on stdin; emit at most one
                  matched hint line (declaration order, first unseen wins) for the adapter's context
                  channel. The per-session seen-set fires each hint once per --session (a /clear
                  = a new session = re-armed). Needs --manifest
  shutdown        Graceful live-agent signoff: run the final context save BEFORE teardown, then
                  soft-stop. The spt shutdown lifecycle path
  owner-shutdown  A shell suspends its linked owner directly, bypassing agent comms — gated by the
                  manifest can_shutdown pre-consent grant, fail-closed. The firing shell cascades
                  offline with its siblings, by design
  help            Print this message or the help of the given subcommand(s)

Options:
      --adapter <ADAPTER>
          adapter_name — the calling harness adapter. Optional (ADR-0021): an explicit
          name[:profile] override for adapter dev/iteration. Omitted, listen resolves the owning
          adapter/profile at bind from the seed's parent pid (host_binaries → active-profile pointer
          → registered_at_ms)

      --manifest <MANIFEST>

      --subnet <SUBNET>          Home subnet for a NEW endpoint (required on a multi-subnet node —
                                 home is assigned at creation, never guessed)

      --type <ENDPOINT_TYPE>           The endpoint type tag (info.json state). Defaults to
                                       live_agent (the agent host); a non-agent endpoint — e.g. a
                                       gateway — binds with its own open-type tag
                                       (REQ-EP-1/REQ-EP-6). A revive keeps the prior type unless
                                       this overrides it [default: live_agent]

the auth (mirrors emit). The frame, if any, prints to stdout

Usage: spt api drive-poll --link <LINK> <ID>

### spt api tunnel

```text
Use the shell end of the opaque byte TUNNEL: a held, reliable-ordered QUIC stream the channel
taxonomy never reinterprets (first consumer: USB/IP URB traffic). send pipes raw stdin into the
tunnel; recv drains buffered bytes to raw stdout. The link token is the auth (mirrors
drive-poll); the stream resolves only under the live link generation. Poll-drained at the surface

## spt endpoint

```text
Endpoint operations: list, lifecycle, fork, digest, access.

The noun home for per-endpoint verbs (M8 decision 1). Bare spt endpoint renders the merged listing
— every member subnet's endpoints grouped by subnet, this session's own endpoint pinned distinctly
at the top.

Usage: spt endpoint [COMMAND]

Commands:
  list         Merged endpoint listing (the bare spt endpoint view)
  run          Bring up an spt-hosted harness endpoint into a broker-held PTY
  fork         Fork an endpoint into another subnet as a NEW identity
  suspend      Rest an endpoint cold (the suspend edge)
  wake         Wake a resting endpoint in place
  shutdown     Gracefully shut down an agent's own endpoint
  stop         Soft-stop a perch (spool preserved)
  rename       Rename an endpoint's logical id across its on-disk state
  purge        Permanently remove an endpoint and every record keyed on it
  digest       Show a session's live activity buffer (session digest)
  access       Endpoint access whitelist for unsolicited off-node inbound
  description  The endpoint's service-description blurb (ex-resources)
  role         Show or set the endpoint's durable role — a broad statement of purpose stored in
               the mind (tracked/agents/<id>/live-role.md), which replicates with the agent and
               renders FIRST at start-transition context injection. Bare role prints the current
               role; --overwrite <file> replaces it from a file. This is the sole writer of
               the role — no automated path (reconcile / echo-commune / signoff) ever mutates it
  help         Print this message or the help of the given subcommand(s)

Options:
  -h, --help
          Print help (see a summary with '-h')
```

### spt endpoint list

```text
Merged endpoint listing (the bare spt endpoint view).

Every member subnet's endpoints grouped by subnet, with this session's own endpoint pinned at the
top, AND this node's local perches merged in (so a just-online endpoint not yet advertised still
shows — spt whoami is a thin alias and must see its own perch). --subnet filters the subnet view
to one subnet; --detail adds each endpoint's description blurb (the resource-registry yellow-pages
projection).

Usage: spt endpoint list [OPTIONS]

Options:
      --subnet <SUBNET>
          Limit the subnet view to one subnet

      --detail
          Add each endpoint's description blurb to the rows

  -h, --help
          Print help (see a summary with '-h')
```

### spt endpoint run

```text
Bring up an spt-hosted harness endpoint into a broker-held PTY.

Spawns the adapter's [session.self] command into a broker-owned PTY (the harness self-registers
its perch on bind), then starts / attaches / views per the terminal-action flag. The endpoint id
rides argv so the harness binds to exactly it. This is the non-interactive core (the interactive
picker lands in a later wave); the flags cover every terminal action so a spt-<id> shortcut can
bake a fully non-interactive launch.

Usage: spt endpoint run [OPTIONS]

Options:
      --adapter <ADAPTER>
          The harness adapter to host: <adapter>[:profile] (must be a registered kind="harness"
          adapter on this node). Omit (with --id) to launch the interactive picker

      --id <ID>
          The endpoint id to bring up (charset: alphanumeric, -, _). Omit (with --adapter) to
          launch the interactive picker

      --create
          Mint a fresh session (the default; explicit so a non-interactive shortcut can bake
          create-vs-resume). Conflicts with --resume

      --resume <RESUME>
          Resume a prior session id instead of minting a fresh one

      --start
          Start the endpoint and return immediately (no attach)

      --attach
          Attach a local terminal after bringup (the default action)

      --view
          Attach read-only after bringup (watch; forward no input)

  -h, --help
          Print help (see a summary with '-h')
```

### spt endpoint fork

```text
Fork an endpoint into another subnet as a NEW identity.

Home subnets are immutable — fork is the cross-subnet move, never a re-home. Seeds the fork with a
one-time copy of the source's mind (live + project tiers); the two diverge immediately (no ongoing
sync). The source is untouched unless --delete-source. Same-node only today (one node holds one
perch per name, so a local fork needs a new id).

Usage: spt endpoint fork [OPTIONS] --subnet <SUBNET> <SRC> <NEW_ID>

Arguments:
  <SRC>
          The source endpoint (must exist on this node)

  <NEW_ID>
          The fork's id (must differ from the source on the same node)

Options:
      --subnet <SUBNET>
          The fork's home subnet — the target (must be a member)

      --delete-source
          Delete the source endpoint (perch + tracked mind) after the copy

  -h, --help
          Print help (see a summary with '-h')
```

### spt endpoint suspend

```text
Rest an endpoint cold (the suspend edge).

The resting state machine's suspend edge. From dormant — or straight from active, in which case the
final context save still fires first. Accepts a qualified id@node to suspend an instance on a
paired peer.

Usage: spt endpoint suspend <ID>

Arguments:
  <ID>
          The endpoint id (qualified id@node reaches a paired peer)

Options:
  -h, --help
          Print help (see a summary with '-h')
```

### spt endpoint wake

```text
Wake a resting endpoint in place.

Re-activates the existing seat (state's already there — no fresh spawn), resurfaces undismissed
notifications, and requests an immediate context freshness pull from trusted peers. Accepts a
qualified id@node for an instance on a paired peer.

Usage: spt endpoint wake <ID>

Arguments:
  <ID>
          The endpoint id (qualified id@node reaches a paired peer)

Options:
  -h, --help
          Print help (see a summary with '-h')
```

### spt endpoint shutdown

```text
Gracefully shut down an agent's own endpoint.

Soft-stops the listener, then the suspend edge — the final context save fires and persistent shells
cascade offline with it.

Usage: spt endpoint shutdown [ID]

Arguments:
  [ID]
          The endpoint id (defaults to the session's own perch)

Options:
  -h, --help
          Print help (see a summary with '-h')
```

### spt endpoint stop

```text
Soft-stop a perch (spool preserved).

Removes the ready marker and unregisters the perch; the spool is preserved.

Usage: spt endpoint stop <ID>

Arguments:
  <ID>
          Perch id to stop

Options:
  -h, --help
          Print help (see a summary with '-h')
```

### spt endpoint rename

```text
Rename an endpoint's logical id across its on-disk state.

Rippled everywhere the id appears: the endpoint's perch dir, its nested companion/worker perches,
and every record naming it. Refuses while the perch is live (stop it first).

Usage: spt endpoint rename <OLD_ID> <NEW_ID>

Arguments:
  <OLD_ID>
          The endpoint's current (bare) id

  <NEW_ID>
          The new (bare) id — charset-validated; :/@ are reserved

Options:
  -h, --help
          Print help (see a summary with '-h')
```

### spt endpoint purge

```text
Permanently remove an endpoint and every record keyed on it.

Deletes the perch tree (including its nested companion/worker perches and shells), the registry
address, the endpoint's context branches, and its node-local trust rows. Local only. Offline-only:
refuses while the endpoint is online — stop it first, or pass --force to stop-then-purge.
Irreversible; confirms interactively unless --yes.

Usage: spt endpoint purge [OPTIONS] <ID>

Arguments:
  <ID>
          The endpoint id to remove

Options:
      --yes
          Skip the interactive confirmation (for scripts / CI)

      --force
          Stop the endpoint first if it is online, then purge

  -h, --help
          Print help (see a summary with '-h')
```

### spt endpoint digest

```text
Show a session's live activity buffer (session digest).

The at-a-glance "what is this agent doing now" view — a projection of the endpoint's normalized
session logs. Pulls a snapshot, or --follows the delta-stream. Local endpoints only.

Usage: spt endpoint digest [OPTIONS] <ID>

Arguments:
  <ID>
          The (local) endpoint id to read

Options:
      --follow
          Stream live changes instead of a one-shot snapshot (Ctrl-C to stop)

      --json
          Emit structured JSON instead of the human-glanceable render

  -h, --help
          Print help (see a summary with '-h')
```

### spt endpoint access

```text
Endpoint access whitelist for unsolicited off-node inbound.

Controls which origin nodes may send an endpoint unsolicited off-node inbound. Absent entry = open;
allow flips the endpoint to restricted; revoking the last node leaves it locked down; open
deletes the restriction.

Usage: spt endpoint access <COMMAND>

Commands:
  allow   Whitelist a node for an endpoint (creates the restriction if absent)
  revoke  Remove a node from an endpoint's whitelist. Never widens: revoking the last node leaves
          the endpoint locked down (all unsolicited refused)
  open    Delete an endpoint's restriction entirely — back to default-open
  list    List restrictions (all endpoints, or one)
  help    Print this message or the help of the given subcommand(s)

Options:
  -h, --help
          Print help (see a summary with '-h')
```

### spt endpoint description

```text
The endpoint's service-description blurb (ex-resources).

Bare description shows your own; set authors it. The cross-node projection over every visible
endpoint is endpoint list --detail.

Usage: spt endpoint description [COMMAND]

Commands:
  set   Author this endpoint's blurb (the agent refines its own at runtime; an empty string clears
        it back to the node-config seed)
  show  Show a local endpoint's authored blurb (the bare description view)
  help  Print this message or the help of the given subcommand(s)

Options:
  -h, --help
          Print help (see a summary with '-h')
```

### spt endpoint role

```text
Show or set the endpoint's durable role — a broad statement of purpose stored in the mind
(tracked/agents/<id>/live-role.md), which replicates with the agent and renders FIRST at
start-transition context injection. Bare role prints the current role; --overwrite <file>
replaces it from a file. This is the sole writer of the role — no automated path (reconcile /
echo-commune / signoff) ever mutates it

Usage: spt endpoint role [OPTIONS]

Options:
      --id <ID>                Which local endpoint (auto-detected from the session if omitted)
      --overwrite <OVERWRITE>  Replace the role with the contents of <file> (the only writer)
  -h, --help                   Print help
```

## spt how-to

```text
Task-oriented instructions for agents: how-to <topic>.

The binary's own usage guidance, written for an agent to read and follow. Bare how-to lists the
topics.

Usage: spt how-to [TOPIC]

Arguments:
  [TOPIC]
          The topic to print (omit to list available topics)

Options:
  -h, --help
          Print help (see a summary with '-h')
```

## spt ready

```text
Become reachable: register the perch and listen (blocks).

Drains the spooled backlog first; each received message prints to stdout. With --once, runs a single
drain+receive cycle and exits.

Usage: spt ready [OPTIONS] <ID>

Arguments:
  <ID>
          This agent's perch id

Options:
      --once
          Run a single drain+receive cycle, then exit (one-shot fallback for harnesses that cannot
          host a long-running listener)

      --subnet <SUBNET>
          Home subnet for a NEW endpoint (required on a multi-subnet node — home is assigned at
          creation, never guessed)

  -h, --help
          Print help (see a summary with '-h')
```

## spt ring

```text
Send and block for a reply (body read from stdin).

The reply body is printed to stdout; gives up after --timeout seconds.

Usage: spt ring [OPTIONS] <TARGET>

Arguments:
  <TARGET>
          Target perch id

Options:
      --from <FROM>
          Sender id (auto-detected from session if omitted)

      --timeout <TIMEOUT>
          Seconds to wait for a reply before giving up
          
          [default: 60]

  -h, --help
          Print help (see a summary with '-h')
```

## spt send

```text
Send a message (body read from stdin); fire-and-forget

Usage: spt send [OPTIONS] [TARGET]

Arguments:
  [TARGET]  Target perch id. May be omitted when --reply-to is given

Options:
      --from <FROM>          Sender id carried structurally as the message from (auto-detected
                             from session if omitted)
      --reply-to <REPLY_TO>  Reply to this sender; sets the target and labels output REPLIED
      --deferred             Spool only (deferred / hook channel) — no live wake
      --user-msg             Request the user-msg type (the user's authority). Honored only from a
                             user-backed origin (a Gateway endpoint, or the local user's own CLI);
                             an agent-family sender is re-stamped to plain msg (REQ-MSG-5)
  -h, --help                 Print help
```

## spt shell

```text
Shell instances: mint, list, drive, tear down owned surfaces.

The driven surfaces this agent owns. spawn MINTS a new instance identity (<adapter>-<n>) — it is
not the online switch; bringing an existing offline instance back is relink / persistent / wake.

Usage: spt shell <COMMAND>

Commands:
  spawn     Mint a NEW shell instance of a registered kind="shell" adapter: canonical id
            <adapter>-<n> (smallest free n; teardown frees slots), starting offline (the launch +
            bind handshake brings it online)
  list      List this owner's instances: canonical id, alias, adapter, status
  teardown  Destroy an instance (perch removed; mint slot + alias freed)
  rename    Set/replace an instance's alias (owner-unique)
  cmd       Drive the shell with a typed capability command (the durable command channel): the op +
            positional args are vocabulary-checked against the manifest's [shell.capabilities],
            spooled on the shell perch, and drained by the manifest's command_receipt mode (relay
            / stdin)
  drive     Drive the shell with a typed, EPHEMERAL control payload: the owner→shell mirror of
            sensory. The drive-type is vocabulary-checked against [shell.drive], held in a single
            latest-wins in-memory slot on the daemon, and drained by the shell's api drive-poll
            --link. NEVER spooled — an offline shell drops the payload with a diagnostic (control
            is live-or-drop, never replayed)
  tunnel    Use the shell's opaque byte TUNNEL: a held, reliable-ordered QUIC stream the channel
            taxonomy never reinterprets (first consumer: USB/IP URB traffic). send pipes raw stdin
            bytes into the tunnel; recv drains buffered bytes to stdout. The shell opts in via
            [shell.tunnel]; the tunnel lives for the link (a link-break closes it). Poll-drained
            at the surface
  send      Send a text and/or file payload down the durable 2-way text+file channel (agent→shell;
            the shell answers via ordinary spt send). File transfers are progress-queryable by
            xfer id
  relink    Bring an existing offline (persistent) instance back online: re-spawns the binary with a
            fresh link token; the perch onlines at its bind
  help      Print this message or the help of the given subcommand(s)

Options:
  -h, --help
          Print help (see a summary with '-h')
```

### spt shell spawn

```text
Mint a NEW shell instance of a registered kind="shell" adapter: canonical id <adapter>-<n>
(smallest free n; teardown frees slots), starting offline (the launch + bind handshake brings it
online)

Usage: spt shell spawn [OPTIONS] <ADAPTER>

Arguments:
  <ADAPTER>  The providing shell adapter (must be registered + active)

Options:
      --alias <ALIAS>  Optional owner-unique friendly label (interchangeable with the canonical id
                       for addressing; never obscures the adapter)
      --owner <OWNER>  Owning endpoint id (auto-detected from session if omitted)
  -h, --help           Print help
```

### spt shell list

```text
List this owner's instances: canonical id, alias, adapter, status

Arguments:
  <SHELL_REF>  Canonical id or current alias
  <ALIAS>      The new alias

Options:
      --owner <OWNER>  
  -h, --help           Print help
```

### spt shell cmd

```text
Drive the shell with a typed capability command (the durable command channel): the op + positional
args are vocabulary-checked against the manifest's [shell.capabilities], spooled on the shell
perch, and drained by the manifest's command_receipt mode (relay / stdin)

Usage: spt shell cmd [OPTIONS] <SHELL_REF> [OP]...

Arguments:
  <SHELL_REF>  Canonical id or alias
  [OP]...      The capability op + args (vocabulary-checked against the manifest)

Options:
      --owner <OWNER>  
  -h, --help           Print help
```

### spt shell drive

```text
Drive the shell with a typed, EPHEMERAL control payload: the owner→shell mirror of sensory. The
drive-type is vocabulary-checked against [shell.drive], held in a single latest-wins in-memory
slot on the daemon, and drained by the shell's api drive-poll --link. NEVER spooled — an offline
shell drops the payload with a diagnostic (control is live-or-drop, never replayed)

Usage: spt shell drive [OPTIONS] --type <DRIVE_TYPE> <SHELL_REF> <PAYLOAD>

Arguments:
  <SHELL_REF>  Canonical id or alias
  <PAYLOAD>    The opaque control payload (descriptive text / encoded blob reference)

      --type <DRIVE_TYPE>  The drive payload type (vocabulary-checked against [shell.drive])
      --owner <OWNER>      
  -h, --help               Print help
```

### spt shell tunnel

```text
Use the shell's opaque byte TUNNEL: a held, reliable-ordered QUIC stream the channel taxonomy never
reinterprets (first consumer: USB/IP URB traffic). send pipes raw stdin bytes into the tunnel;
recv drains buffered bytes to stdout. The shell opts in via [shell.tunnel]; the tunnel lives for
the link (a link-break closes it). Poll-drained at the surface

Usage: spt shell tunnel [OPTIONS] <SHELL_REF> <DIRECTION>

Arguments:
  <SHELL_REF>  Canonical id or alias
  <DIRECTION>  send (raw stdin → tunnel) or recv (tunnel → raw stdout)

Options:
      --owner <OWNER>  
  -h, --help           Print help
```

### spt shell send

```text
Send a text and/or file payload down the durable 2-way text+file channel (agent→shell; the shell
answers via ordinary spt send). File transfers are progress-queryable by xfer id

Usage: spt shell send [OPTIONS] <SHELL_REF> [TEXT]

Arguments:
  <SHELL_REF>  Canonical id or alias
  [TEXT]       The text payload

Options:
      --file <FILE>    A file to transfer to the shell
      --owner <OWNER>  
  -h, --help           Print help
```

### spt shell relink

```text
Bring an existing offline (persistent) instance back online: re-spawns the binary with a fresh link
token; the perch onlines at its bind

Usage: spt shell relink [OPTIONS] <SHELL_REF>

Arguments:

Options:
      --owner <OWNER>  
  -h, --help           Print help
