…agnostics `shell::pty::open` grows `program`, `args`, and `env`. Without them a session is still the user's login shell, so nothing changes for the console terminal. With them a session IS one program with no shell around it, which is what an agent CLI rendered in its own console page needs. A caller that can open a login shell can already run any program by typing it, so this is reach, not privilege; per-session `env` reuses `shell::exec`'s deny-only rule, and an exec-hijacking key (`PATH`, `LD_*`, `DYLD_*`, `BASH_ENV`, ...) refuses the whole call rather than being dropped silently. The output handler is now validated by SHAPE — `iii::<worker>-ui::pty-output::console-<browser-id>` — instead of being pinned to this worker's own page, because a worker that runs its own program in a session serves its own page and therefore its own handler. A session still cannot be pointed at an arbitrary function on the bus. Adds `shell::pty::sessions`: live sessions with program, cwd, status, last sequence, replayable frames/bytes, and current output target, no credentials. It separates a terminal that shows nothing because nothing was produced from one whose frames the browser dropped. Tags the `shell::pty::*` lifecycle functions `trace_hidden` (see docs/sops/trace-hidden-functions.md), so the traces page no longer opens with one span group per keystroke and redraw, and allows the read-only `shell::pty::sessions` for agents ahead of the lifecycle deny. Tests: 5 new (requested program runs with argv, env reaches the child, a dangerous env key refuses the session, foreign console-UI handlers accepted / malformed refused, diagnostics report program and replay state). Full shell suite green; verified live against a running engine.
One full-pane xterm bound to a `shell::pty` session that runs an agent CLI.
The session belongs to the shell worker, so this package is the only new part:
it asks `<worker>::terminal::describe` what to run and where, then drives
`shell::pty::open/write/resize/attach/detach`. The page never chooses a
program — that is what keeps a terminal page from being a shell in disguise.
Source-only, and consumed by claude-cli/ui and pi-cli/ui, because the two
pages differ by three constants (worker name, title, description) and nothing
else. Registers the UI workspace entries for both.
Carries the parts a TUI over a fire-and-forget bus needs: an ordered writer
that holds out-of-order frames and re-attaches when a gap stalls, a per-tab
lease in sessionStorage that reattaches across remounts and reloads (full
replay, because a remount builds an empty xterm and an agent repaints only on
change), a frame/byte counter in the status line so a blank pane can be told
apart from a dead one, and bus errors read out of plain `{code, message}`
objects as well as Errors.
A console page that always runs Claude Code, never a shell. The worker installs the CLI on the terminal host, equips a workspace with the iii skills and engine notes, answers `claude-cli::terminal::describe` with what to run, and turns the session's hook events into AgentEvent frames on `agent::events` — so a terminal turn renders in the console exactly like a headless agent worker's turn (`claude-code`, `pi`). Everything it does to a filesystem or a process goes through the `shell` worker, which is also the worker that owns the terminal: `shell::pty::open` runs the CLI, `shell::exec` installs it and equips the workspace, `coder::read-file` reads the files back. So the agent, its workspace, and its installer are on ONE host whether or not that is this worker's host, and nothing depends on a shared directory. Observability is the stream, not the transport. `claude-cli::activity` maps hooks to frames — a user message per prompt, an assistant message per tool call, a `function_execution_start`/`end` pair with a real duration, and `turn_end` + `agent_end` on stop — and is tagged `internal` + `trace_hidden` so one call per hook does not fill the traces page. The hooks reach it with `iii trigger ... --json "$(cat)"`: the bus, so it works cross-host, and one expansion, so a prompt containing shell syntax stays data. Only this worker's keys in `.claude/settings.json` are rewritten, and `CLAUDE.md` keeps everything outside the worker's marked block. Config is Path B (no committed config.yaml): the `claude-cli` configuration entry holds the binary path, argv, workspace, install/setup toggles, and the events stream, and a change re-runs the preparation for the next session. The console page assets are compiled into `src/ui-assets.generated.ts` by `ui/build.mjs` — the Node equivalent of the Rust workers' `include_str!`, because `deploy: bundle` ships one file. Tests: 12 (hook→frame mapping including a failed tool, a Post with no Pre, and unmapped events; the whole workspace preparation against a fake shell worker, including that it keeps the operator's half of settings.json and their own notes). Verified live against a running engine and console: the page opens Claude Code through `shell::pty`, and a hook sequence lands as frames.
Same shape as `claude-cli`, for pi (pi.dev): a console page that always runs pi, a workspace equipped with the iii skills and engine notes, and turns that land on `agent::events` so the console renders them like any other agent worker's. The page is the shared `@iii-workers/agent-terminal-ui` with pi's name on it; the terminal is a `shell::pty` session; the workspace and the install run through the `shell` worker. Where Claude Code has shell hooks, pi has extensions — so the worker writes `.pi/extensions/iii-activity.ts` into the workspace and pi discovers it there (a session an operator starts by hand in the same directory reports its turns too). The extension posts pi's lifecycle events with `pi.exec` on the `iii` CLI, which keeps the payload an argument rather than a shell string, and `pi-cli::activity` maps them onto the same AgentEvent frames. Sessions run with `-a` by default: pi loads project-local extensions only in a trusted directory, so without it every session opens with a trust prompt and never loads the extension that reports what pi did. The flag is in `args`, so an operator who would rather answer that question can drop it. Tests: 9 (pi event → frame mapping including a failed call and unmapped events; the workspace preparation against a fake shell worker, including the extension contents and that AGENTS.md keeps the operator's own text). Verified live: the worker resolves pi on the terminal host, prepares the workspace, and its page bundle registers the `pi-cli` page and opens a session through `pi-cli::terminal::describe` → `shell::pty::open`.
A terminal that quietly bills a metered API key when the operator thinks they
are on a subscription is a bill, not a bug report. So the status bar carries a
badge, and `<worker>::auth::status` answers the same question on the bus:
`team subscription · you@example.com · org`, `API key billing ·
ANTHROPIC_API_KEY`, or `not signed in`.
Claude's answer has a trap in it. With `ANTHROPIC_API_KEY` set, `claude auth
status` still reports `authMethod: claude.ai` — the account IS signed in —
while billing has moved to the key; the CLI says so ("ANTHROPIC_API_KEY or
another auth source is set and takes precedence over your claude.ai login")
and a bogus key 401s the turn. So the badge reads `apiKeySource`, not
`authMethod`, and the tooltip spells out that the login is signed in but not
billed.
pi keeps credentials per provider, so pi-cli asks `pi auth check --provider
<auth_provider> --json` (new setting, default `anthropic`) and reports the
credential KIND — OAuth login vs api key. `--credentials` is deliberately not
passed: the page needs the kind, never the credential. That command exits 1 for
a provider that is not ready and still prints the JSON saying why, so the exit
code is not read as the answer.
Both functions read the CLI on the terminal host, which is the host the session
runs on, so the badge is the session's own answer rather than this worker's
environment. Both stay agent-denied — they carry the operator's account,
organization, and billing mode; the console page reaches them as
user-initiated calls, which is not the agent path.
The badge is neutral ink for a subscription and coloured only for the two cases
an operator might not expect: a metered key, or no credentials at all. A worker
that does not answer leaves the badge off — the terminal is the point.
Tests: 10 (both parsers, including the signed-in-but-not-billed case and
non-JSON output). Verified live in the console status bar in both directions:
`team subscription · anthony@motia.dev · iii`, then `API key billing ·
ANTHROPIC_API_KEY` after setting the key on the shell worker, and back.
The login sections claimed one login in the terminal covers a headless sibling "on the same host". That is only true when the sibling is a host process. Compose starts a `path://` container and a registry BINARY payload as host processes, and a registry BUNDLE payload — Node `deploy: bundle`, which is `claude-code`, `pi`, and both of these workers — in a microVM with its own rootfs (`iii-compose/src/lifecycle.rs`). Only the container's own config directory is shared into that guest, and compose v1 has no volume field, so a VM-booted worker cannot read the host's `~/.claude`. Both terminals are unaffected, and it is worth saying why: the CLI runs inside the `shell` worker, which is a Rust binary payload and therefore a host process, so the credentials are that host's and these workers' own rootfs never enters into it. For a registry-installed headless sibling the credentials have to travel by a channel a VM has: `environment` / `env_file` on its container, or the `auth-credentials` vault over the bus — which is why that vault exists, and why `provider-claude-code` reads it rather than the credentials file.
…g it The hooks and the pi extension reach the bus by running the `iii` CLI on the terminal host, and that host is only this worker's host by coincidence — the CLI runs inside `shell`, which is a host process today because its registry payload is a binary. The day binary workers get VM-booted, that guest may have no `iii` in it, and every hook becomes a silent no-op: the terminal still works, `agent::events` just stays empty forever, with nothing saying why. So the probe result is now carried rather than discarded. `prepareWorkspace` returns the CLI it found as `bridge`, warns when there is none, and folds the reason into `detail`; `<worker>::terminal::describe` reports both, so "the terminal works but no turns arrive" is one call to diagnose instead of a log hunt. The hooks are still written when the CLI is missing — a CLI installed later starts working with no rewrite. Both READMEs now state the coupling instead of implying a shared machine: what holds today holds because shell is a host process, and what changes if that stops being true (the login belongs to the guest's rootfs, the workspace is not the operator's checkout, and the bridge may be absent). Tests: 4 (bridge found and reported; bridge missing → mute, said out loud, and the hooks/extension still written).
claude-cli did one thing claude-code could not — put Claude Code in a terminal a person types into — and paid for it with a second worker that needed its own login, its own configuration entry, and its own copy of the AgentEvent types. The two halves run the same CLI against the same home directory, so they are one worker. The move is mechanical: the terminal sources become `claude-code/src/terminal/*` and its ids join the `claude::` namespace (`claude::terminal::describe`, `claude::terminal::activity`, `claude::auth::status`, `claude::ui-content`). Three duplicates die on the way in — the emitter, the AgentEvent types, and the whole configuration module — because the headless half already had each one. The terminal's settings are now a `terminal` block on the claude-code config entry, so there is one form on the Workers tab rather than two. Preparing the terminal host (install the CLI, equip the workspace, write the hooks) can take minutes on a cold host, so it is chained off the config reload instead of awaited: `claude::run` registers whether or not there is a terminal host to prepare, and a settings change still re-runs it for the next session. The workspace moves with the name: `<shell root>/claude-code`, not `claude-cli`. The old directory is left alone — nothing reads it — and the login is unaffected, because it lives in the terminal host's home directory and never lived in the workspace. Verified against a live engine: both halves register, `claude::terminal::describe` answers with the resolved binary, `claude::auth::status` reports the subscription that pays, `claude::ui-content` serves the page, and a hook event still translates into AgentEvent frames.
The claude-cli README and skill move into claude-code rather than disappearing: what the workspace gets, which plan a session spends, and how a login belongs to a rootfs are all still true, and the deployment table now answers for both halves — the terminal runs inside `shell` (a host process, so it shares the host login), while a headless turn runs inside this worker's own container, which is a microVM when installed from the registry.
The lockfile still listed the moved UI project, and shell's PTY tests used `claude-cli-ui` as their example of a foreign console handler. Both now name the page that exists. 674 shell lib tests still pass.
…'s choice 13px was a guess baked into two files, and on a dense display it reads small enough that people lean toward the screen. Every pane now carries a stepper — 8 to 40 px, 14 by default, with Ctrl or ⌘ + scroll for the impatient. The value belongs to the browser, not to a worker: the same engine read from a laptop and from a wall display wants two different answers, and a size in the configuration worker would force one on both. So it lives in localStorage, in one new source-only package both UIs bundle. One value, read by shell's docked panes and by the claude and pi pages alike — a click in one pane moves the terminal beside it, and a `storage` event carries it to the other console tab. Changing it never rebuilds a terminal, which would drop the scrollback: the size enters the mount effect through a ref, and a separate effect sets `options.fontSize` and refits, so the PTY hears the new geometry through the ordinary resize path. Also fixes the palette conflict this made obvious. The agent terminals used to follow the console theme, and a light console left Claude Code's dim gray on white beside pi's own dark background — because a CLI paints its interface in ANSI colors chosen for a dark terminal and never learns the page went light. They are now dark whatever the console is, which is what every terminal emulator inside a light application does. Verified live against the running compose project: `claude::ui-content` and `shell::ui-content` both serve pages carrying the control, 16/16 containers ready afterwards. 318 shell UI tests pass, 6 of them new.
…r says what it shows "billing unknown" while plainly signed in had two causes, one on each side of the call. The session had no identity. Claude Code keeps subscription credentials in the OS keychain and finds them by the current user, and a worker's environment is not the operator's shell: compose clears the environment and re-seeds an allowlist from the daemon's own, so a daemon started without `USER` hands every child a blank one. `claude auth status` then reported `loggedIn: false` next to a keychain that held the login — reproduced exactly with `env -i HOME=... claude auth status`, and bisected to `USER` alone. Both workers now ask the terminal host who it is (`id -un`) and put `USER` and `LOGNAME` into every session and into the billing probe. The probe threw away the answer. `claude auth status` exits 1 when nobody is signed in and still prints the JSON that says so, and the old code read a non-zero exit as silence — turning an honest "not signed in" into "billing unknown". It now reads stdout whatever the exit code, the way pi-cli's check already did. Sessions also carry `COLORFGBG=15;0`. The page paints a dark terminal, an agent TUI picks its palette from that variable, and pi was rendering half its interface in dark ink on a dark background; pi additionally defaults to `--use-theme dark` now, since it has a flag for it. Both status-bar values gained a label. A bare "14" and a bare plan name make the reader guess what they are looking at; "Font" and "Billing" cost two words each. Verified against the running project: `claude::auth::status` returns the team subscription again, `pi-cli::auth::status` returns an honest "not signed in" instead of "unknown", and both describe calls carry USER/LOGNAME/COLORFGBG. 95 claude-code and 15 pi-cli tests pass, with new coverage for the session environment.
…dge names every provider Three complaints, one cause each. **"[pi-cli: replay truncated]", constantly.** A remount replays the whole ring buffer so the fresh xterm has a picture, but the buffer is finite and an agent TUI repaints on every keystroke — so a tab left alone comes back to a replay that starts mid-frame. The page wrote a notice into the terminal and then painted the fragments, which lands inside whatever the agent was drawing. Now a truncated replay is skipped entirely: the writer starts from the newest sequence the worker still holds and the agent is asked to paint the screen it is actually on, with a one-row resize and back — a SIGWINCH, which every full-screen TUI answers with a full redraw. **Not always responsive.** Same truncation, in the mid-session recovery path: the writer waited for a gap that had already fallen off the end of the buffer, so every later frame queued behind a frame that would never arrive. A terminal that has stopped applying output reads exactly like a terminal ignoring the keyboard. **A new session instead of the old one.** The lease lived in sessionStorage, which the browser clears when the tab closes — so closing the console and returning started a second agent in the same workspace and left the first one running, invisible. It lives in localStorage now, and a lease written by the old build is read once and carried over so today's open terminals survive the change. **"anthropic: not signed in" with a working OpenAI key.** pi is not one account: the badge asked about the single configured provider and called the whole terminal signed out. It now reads the provider NAMES from pi's own auth store and asks `pi auth check` about each — "openai (API key)", "2 providers · openai, anthropic", or "no provider signed in" when there is genuinely nothing. Credentials are still never read: the store gives names, pi gives state. Verified live: `pi-cli::auth::status` now returns openai (API key), the served page carries the localStorage lease and the repaint call, and no page still contains the "replay truncated" string. 19 pi-cli tests pass, 9 of them new.
…session A lost lease used to strand a running agent. The reconnect token is what proves a caller opened a session, so a browser that clears its storage — or a different browser entirely — cannot reach the terminal again, while the program keeps working in the workspace with nobody watching. The page's only option was to start a second agent beside the first. `shell::pty::adopt` re-owns an unattached session without a token, under two rules that keep it from being a way in rather than a way back: - The session must be UNATTACHED. A terminal someone is watching is never taken from them. - The new output handler must name the same console page as the one it replaces. The browser id may differ — that is the point — but `iii::claude-ui::…` cannot adopt a session whose output went to `iii::pi-cli-ui::…`. Credentials rotate on adoption, so the previous owner's are dead, and the idempotent-attach retry state is cleared with them: a replayed attach from the old owner cannot resurrect it. `shell::pty::sessions` now reports each session's `ui` — which console page it belongs to, never which browser — because a page needs to recognise its own orphan without being handed anyone's identity. The agent page uses it: before opening a new session it looks for a detached one from its own page family running the same program, adopts it, and asks the agent to repaint. An older shell worker without the function simply opens a fresh session, as before. 679 shell lib tests pass, 5 of them new: adoption rotates and invalidates, refuses a live terminal, refuses a foreign page, and closes the door on a replayed attach.

Inline comments:
In `@claude-code/README.md`:
- Around line 5-6: Update the README description near the shared-login claim to
state that the headless and terminal halves share an events stream, while login
and credential access depend on the deployment; preserve the existing
distinction that registry bundle deployments isolate the headless worker from
the shell worker’s credentials.
In `@claude-code/src/terminal/auth.ts`:
- Around line 135-138: Update the command construction in the auth-status flow
around resolveExecutable and exec so the interpolated executable path is
shell-quoted before appending the auth status arguments. Preserve the existing
readStatus handling and UNKNOWN fallback while ensuring whitespace-bearing
executable paths are passed as one command argument.
In `@claude-code/src/terminal/host.ts`:
- Around line 69-79: Update readFile to distinguish a genuinely absent file from
other coder::read-file failures instead of mapping every failure to null. Adjust
writeNotes and writeHooks to proceed with replacement only when the read
confirms absence, and skip preservation-sensitive writes when the read returns
an error result.
Apply the same fix in `@pi-cli/src/host.ts` around lines 69 - 79: The same
failed-read-to-missing conversion can overwrite AGENTS.md content.
In `@claude-code/src/terminal/workspace.ts`:
- Around line 208-212: Update the hook construction around HOOK_EVENTS so each
covered event preserves existing hook entries and only appends or reconciles the
worker-owned command entry. Retain unrelated operator commands and existing
matcher structure while ensuring the generated hooks still include the current
command for every event.
In `@packages/agent-terminal-ui/src/index.tsx`:
- Around line 173-179: Update the writer state around base and connect so each
new session attempt explicitly clears all pending frames and resets the sequence
state before calling writer.base(0). Ensure both the lease recovery path and the
fallback session-opening path invoke this reset, preventing frames from a dead
session from being applied to the new stream.
- Around line 180-186: Update feed() so EOF events are not assigned a synthetic
sequence or inserted into pending; defer EOF processing until all pending data
frames have been flushed, ensuring later output is delivered before onEof runs.
Preserve sequence validation and ordering for non-EOF events.
- Around line 738-749: Replace the React onWheel prop around the agent-terminal
viewport with an active native wheel listener registered on containerRef.current
using passive: false, and clean it up on effect teardown. Preserve Ctrl/⌘
detection and preventDefault behavior, but read the current font size from
fontSizeRef.current when calling stepFontSize.
In `@pi-cli/README.md`:
- Around line 10-13: Correct the Claude Code worker identifier from claude-cli
to claude-code in pi-cli/README.md lines 10-13, updating both link text and
repository path, and in pi-cli/skills/SKILL.md lines 26-27. No other changes are
needed.
In `@pi-cli/src/activity.ts`:
- Around line 120-122: Update the generated-ID handling in the tool lifecycle
logic around state.calls so a tool_end event without call_id resolves the same
ID created by tool_start, rather than using the incremented collection size.
Retain pending generated IDs or otherwise enforce stable IDs across both events,
and add coverage for omitted call IDs verifying duration_ms is calculated.
In `@pi-cli/src/index.ts`:
- Around line 63-64: Update the emitter setup around makeEmitter and
registerActivity so activity events resolve config.events_stream at emission
time rather than capturing its initial value. Pass registerActivity a wrapper
that reads the current config stream for every event while preserving the
existing event emission behavior.
- Around line 49-58: Serialize reconcile invocations so concurrent
pi-cli::on-config-change events cannot let an older prepareWorkspace result
overwrite newer state. Update reconcile and its bindConfigTrigger integration to
queue executions or discard stale results, ensuring pi-cli::terminal::describe
observes only the latest configuration.
In `@pi-cli/src/workspace.ts`:
- Around line 55-58: Update the setup flow in prepareWorkspace around
installSkills, writeNotes, and writeExtension to catch failures, append the
failure text to detail, and still return the resolved executable and workspace
so the terminal remains available.
In `@shell/README.md`:
- Around line 221-222: Update the PTY cwd documentation to distinguish jailed
behavior from the fs.allow_unjailed: true behavior: state that cwd is confined
to a configured root in jailed mode, while an empty fs.host_roots configuration
with unjailed access permits the real filesystem. Remove the unconditional claim
that sessions can only start inside a configured root.
In `@shell/src/pty.rs`:
- Around line 875-886: Update reject_dangerous_env and shell::exec to share a
common environment-key validator that rejects empty keys, keys containing '=' or
NUL, and names outside the portable environment-name syntax before applying
is_dangerous_env_key. Preserve the existing deny-list error behavior for valid
dangerous keys and ensure validated keys are the only ones passed to
Command::envs.

…937 An env key now has to BE a key. `shell::exec`, `shell::exec_bg` and `shell::pty::open` checked the deny-list against whatever string arrived, and an environment entry is one `key=value` string — so `PATH=/tmp/evil` read as an unknown, therefore allowed, name, passed the `PATH` rule, and still handed the child a `PATH`. Keys must now be environment variable names (`[A-Za-z_][A-Za-z0-9_]*`), refused before the deny-list runs and shared by both surfaces. A read that failed is no longer read as a file that is absent. `coder::read-file` answers C211 for missing-or-denied, and only that answer means "there is nothing to preserve": a timeout used to come back as `null`, which is how a worker overwrites the `CLAUDE.md`, `.claude/settings.json` or `AGENTS.md` a person wrote. Equipping the workspace is also no longer what makes a terminal usable — a failure there is reported in `detail` and the terminal still opens with a working CLI. Hooks on an event this worker also uses survive. Assigning the event's whole array deleted an operator's formatter from `PostToolUse` on the next boot; only the worker's own entry (recognised by its trigger target) is rewritten now. Interpolated executables are quoted, so a path with a space in it stays one word and `claude auth status` keeps answering the billing question. pi's optional `call_id` no longer breaks a pair: an id this worker invents is remembered until `tool_end` claims it, instead of being re-derived from a pending-call count that moved in between. pi's configuration reloads run one at a time, so an older prepare cannot land last, and the events stream name is read per event rather than captured at boot. In the terminal page, an EOF frame waits for the pending frames instead of taking the next sequence — it used to end a session before its last output arrived and drop that output. Starting on another session's stream now clears what is pending (`base(0)` deleted nothing, so a dead session's frame painted into the fresh terminal). Ctrl/⌘ + wheel binds a native non-passive listener, because React registers wheel handlers as passive and ignores `preventDefault()` inside them. Docs: the shared-login claim is qualified by deployment, the PTY `cwd` claim is split into the jailed and unjailed cases, and `claude-cli` is `claude-code`.

`iii compose` reads `scripts.start` from a worker's `iii.worker.yaml` and uses it whenever the compose file names no `run` of its own, so start instructions belong to the worker, not to every operator's `worker-compose.yaml`. `console` declared none, so a compose file had to spell out `cargo run` for it. It now declares `install`/`start` like `shell` does; the HTTP port stays an operator setting (`http_port` in the stored config, or `--http-port`). `claude-code` and `pi-cli` declare `node ./index.mjs`, which in a published bundle IS the bundle — `dist/bundle/index.mjs` ships as the package root. From a source checkout that path did not exist, so a compose file had to name `dist/index.js` instead. Both workers now ship that entry, forwarding to the compiled output, and the same manifest command starts them either way. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

empty. Preserve normal EOF behavior and add a regression test covering EOF
delivered before the final data frame.

- Around line 66-69: Update endGeneratedId so an unmatched tool_end generates
and returns a fallback ID without storing it in state.generated; retain deletion
and existing ID reuse when a matching start exists. Add a test covering two
id-less tool_end events for the same tool with no starts, asserting they receive
distinct IDs.

The console's trace views group and label by span attributes an agent harness stamps (`console/docs/timeline-span-tags.md`): `iii.session.id` is what "group by session" groups on, `iii.message.id` is one turn, and `iii.tag.kind` / `iii.tag.message` / `iii.tag.display_name` are how a timeline classifies and names a segment. Neither terminal worker carried any of them, so their turns arrived as anonymous `execute <fn>` bars with nothing tying a session's calls together. Both workers now open the same kind of scope the harness opens: the identity in W3C baggage plus a span that starts inside it, which is what makes the tags land (baggage never reaches a span that was already open). Every call the turn makes inherits the keys, in this worker and in the workers it calls. A terminal turn reaches these workers as several separate calls — one per Claude Code hook, one per pi extension event — so a turn id is opened when the prompt arrives and reused until the next prompt. That gives a session's calls one `iii.message.id` without pretending a single span covers the turn. The headless `claude::run` path gets both: one span per turn, and the identity on it. `@opentelemetry/api` becomes an explicit dependency of both workers: setting baggage needs `context.with`, and neither the SDK nor its observability helpers are re-exported on a public subpath. pi-cli resolved it before only by npm hoisting. The install also moved `@anthropic-ai/claude-agent-sdk` to 0.3.245, whose `interrupt()` returns a control response, so `claude::stop`'s handle discards it.

…runs it The console's sub-agent card belonged to one function id: `harness::spawn`. A run started on any other agent worker — `claude::start`, `run::start_and_wait`, a worker nobody has written yet — read as a bare JSON blob, even though it had created a real child session the console already knew about and nested in the sidebar. Nothing about the card is harness-shaped, so nothing about it needs a function id. `components/chat/agent-session` claims a message by its RESPONSE — a session id plus one of the fields only an agent run answers with (`child_session_id`, `started`, `result`, `usage`, `turn_id`) — and renders the same live child card, with the same activity refinement. A session id ALONE is deliberately not enough: a PTY session is a session too, and claiming it would put a sub-agent card on a terminal. The renderer is registered last, so every family keeps its own ids, and it declares no label, no raw redaction and no `display` metadata: prominence is read off `isMatch` alone, so a matches-everything renderer carrying `display` would mark every call in a transcript prominent and stop sequences collapsing. The card renders inside an opened call. The Node workers now start from a source checkout with no compose `run` or `pre_run` line: `index.mjs` — the entry their manifests already name — builds the worker when `dist/` is missing, then starts it. Both carry a `TODO(iii-mono)` to drop that step once `iii compose` honours a manifest's `scripts.install` as the default `pre_run`, which is the real fix; compose reads only `scripts.start` today.

reconcileTerminal committed whichever prepareWorkspace() resolved last, not whichever was queued last: a slow preparation for configuration A could overwrite a faster preparation for configuration B, leaving pi::terminal::describe and pi::auth::status (and their claude-code equivalents) serving A's stale executable/workspace/env for as long as A's prepare took. Each reconcile now stamps a generation and only commits its result while that generation is still current.
Resolves: - claude-code/package.json: keep the branch's @opentelemetry/api addition, take main's iii-sdk downgrade to the currently-released 0.22.1-alpha.25 (this branch had drifted onto an abandoned 0.23.0-rc.2 pin). - console/iii.worker.yaml: both sides added disjoint sections (runtime/scripts here, config/dependencies on main) — kept both. - claude-code/src/iii-prompt.ts, pi/src/iii-prompt.ts: kept this branch's deletion (consolidated into iii-directory/skills/system-prompts/iii-runtime.md by 2994705) and ported main's wording fix into that shared file so it isn't lost. Verified post-merge: claude-code and pi typecheck and their full vitest suites pass against the downgraded SDK; shell and session-manager pass fmt/clippy/test; the worker-dependency and released-SDK compatibility tests pass.

Resolves: console/web/src/components/chat/Message.tsx — main added a session-level agentName profile prop; this branch stamps the per-message worker identity (message.agent). Kept both, message.agent taking precedence since it reflects the actual answering worker, agentName as fallback for turns without one, 'Agent' as the last resort. Note: src/lib/icon-size-conformance.test.ts, src/components/function-trigger/redact-raw.test.tsx and src/components/trigger-activity/TriggerActivityCard.test.tsx fail (missing 'left-full' class) both before and after this merge — confirmed pre-existing in a separate worktree check, not caused by this merge.

Claude Code and pi as terminals on the console, plus the
shellsupport they needed.Two pages appear in the nav — claude and pi — each a full-pane xterm bound to a
shell::ptysession that runs that agent and nothing else. Every prompt and tool call streams ontoagent::events, so a typed turn renders exactly like a headless one.What is here
shell0.12 — a PTY session can run one named program (program,args,envonopen), accept another worker's console page as its output handler, list what is running (shell::pty::sessions), and hand an unattached session back to the page that lost its token (shell::pty::adopt). The lifecycle functions becametrace_hidden: one span per keystroke buried the work worth reading.claude-codeabsorbed the terminal half. One worker, one login:claude::rundrives Claude Code headless,claude::terminal::*drives the same CLI in a session a person types into. The move deleted three duplicates on the way in — the emitter, the AgentEvent types, and a whole second configuration module — and the terminal's settings became aterminalblock on the existing config entry.pi-cliis the same shape for the pi agent, reporting its runs through a.pi/extensionsextension.packages/agent-terminal-uiis the page both inject: ordered writer over unordered bus delivery, a lease that reattaches across reloads, and a status bar that says which plan the session spends.packages/terminal-fontis the 8–40 px type size every terminal in the console shares.Things worth a reviewer's attention
shell::pty::adoptrefuses an attached session and refuses a console page that is not the session's own; credentials rotate and the idempotent-retry state clears, so a replayed attach from the previous owner cannot resurrect it.shell::pty::sessionsreports a page, never a browser. The newuifield is what lets a page recognise its orphan without being handed anyone's identity.claude::terminal::*,claude::auth::status,claude::ui-contentandpi-cli::*are agent-denied: a terminal is opened by a person, from the console, andauth::statuscarries the operator's account and organization.shell::pty::sessionsis allowed — it is read-only diagnostics with no credentials.Testing
shell: 679 lib tests (5 new for adoption), clippy clean at-D warnings.claude-code: 95 tests.pi-cli: 19.shell/ui: 318. Biome clean per worker.claude::auth::statusreturns the subscription that pays,pi-cli::auth::statusenumerates every provider pi holds credentials for, and hook/extension events reachagent::events.Known limits
shell, a host process; if binary workers are ever VM-booted the login moves into that guest, and the workers report theiii-CLI bridge (activity_bridgeonterminal::describe) so a terminal that works whileagent::eventsstays empty is one call to diagnose.🤖 Generated with Claude Code
