Shell state does not survive between tool calls, but the filesystem does. The stamp is the last line written, so a truncated file leaves it unset and the guard aborts instead of running a half-written preamble. + - **New: where to spawn.** The only documented spawn used to create a scratch case, so "spin up workers on this repo" led an agent to do correct-looking work in the wrong directory. The rule is now explicit: hooks (and therefore `stop`/`blocked`) exist only where Codeman created the directory, so a linked case or a raw `workingDir` must synchronize on output markers. `wait:true` is still accepted there and silently degrades to a heuristic `idle`, which is documented as its own trap. + - **New verbs**: interrupt a runaway worker with ESC instead of deleting it, `active-tools` and `run-summary` as structured liveness signals, `auto-resume` for usage limits, the workspace as a high-bandwidth channel, and `GET /api/events` as a fleet watcher. + - `reference/messaging.md` gains a fleet protocol for Claude Code cross-session messaging: peer refs are injected and never discovered (a worker calling `ListAgents` sees the user's real sessions), every message costs a billed turn in both sessions, plus review pairs, mid-task questions, relay chains, mixed fleets, and their failure modes. + - `reference/recipes.md` is renumbered to a flat Flow 1-7 and gains Flow 7, one whole job start to finish: worktree fleet, tasks, gather, a review pass, report, cleanup. + - `reference/endpoints.md` gains an auth section, a symptom gallery keyed on what you actually see in the JSON, and a consolidated limits table. + - **Corrections found by auditing the old text against source**: the input cap is 65536 characters and not 100000 (65537-100000 passes Zod then 400s at the route); `wait.ended` is returned by a _live_ session whose write did not land, so "the session is gone" was wrong recovery advice and `delivered:false` is the discriminator; `DELETE /api/subagents` clears the map rather than killing anything; the trust-dialog auto-accept reads the rendered pane, not the output stream; `claudeMode` is readable globally though not per session; `run-summary` is envelope-wrapped (`.data.summary`); `active-tools` is not empty for `shell` mode; and a session does inherit the server's `CODEMAN_PASSWORD`. + + **Session lineage lines** (`sessionLineageLines`, per-device, desktop default on). A create request may name the session that spawned it, as a `parentSessionId` body field on `POST /api/sessions` and `POST /api/quick-start`, or as an `X-Codeman-Parent-Session` header, and the web UI draws an arc from the parent's tab to each child's. The skill's preamble sets the header once, so every spawn recipe carries it. The value is **resolved rather than trusted**: exact id or a unique prefix of at least eight characters (ids reach agents truncated), it must be a live session the caller can see with the same owner, and anything unresolvable is dropped rather than returning a 400, so a cosmetic field can never fail a worker spawn. It confers no permission and no lifecycle meaning. Rendering is an additional layer on the existing connection-line pass, sharing one batched reflow; desktop only, because the mobile header would bury the overlay. + + **The endpoint drift guard now covers routes it silently could not see.** `test/agent-skill-endpoints-doc.test.ts` matched only bare `app.('path')` registrations under `src/web/routes/`, so routes registered on the server itself (`/api/events`, `/api/events/subscribe`) and any registered with Fastify generics (the approvals routes) were unverifiable.

The caller therefore supplies it — every managed pane already gets `CODEMAN_SESSION_ID` from `session-cli-builder.ts`. Two equivalent inputs, body wins: a `parentSessionId` field on `POST /api/sessions` / `POST /api/quick-start`, or the `X-Codeman-Parent-Session` header, which exists so the agent skill can set it ONCE on its shared curl invocation and have every present and future spawn recipe carry it. + +**Resolved, not trusted** (`resolveParentSessionId()`, route-helpers.ts): exact id first, then a UNIQUE prefix of ≥8 chars (ids reach agents truncated — mux names and a Docker export's `$CODEMAN_SESSION_ID` both carry 8), and an ambiguous prefix resolves to NOTHING rather than to a guess. The parent must be a live session the caller can already see (`canAccessOwned`) AND carry the same owner as the session being created, so a multi-user caller cannot staple their session under someone else's tab. ⚠️ **Everything unresolvable is DROPPED, never a 400**: a stale id from a cached skill preamble must cost a decorative line, not a worker. ⚠️ It is decoration at every layer — never an ownership, permission or lifecycle signal; a child outlives its parent, and the Session ctor refuses a self-parent (reachable only via recovery, where both values come off disk). It rides `toState()` into `session_created` / `session_updated`, so there is **no new SSE event**, and `server.ts`'s recovery path restores it so lineage survives a restart. + +**Rendering is an additional LAYER, not a second pass** (`session-lineage.js`, loadorder 15.6): `_updateConnectionLinesImmediate()` (subagent-windows.js) calls `_appendLineageConnectionLines(svg, rects)` at its tail, exactly like ultracode's two layers, so all of them share ONE batched read→write reflow and the same `tab:` rect cache. Geometry is pure and unit-tested in `computeLineagePath()` (constants.js): both endpoints live in one horizontal strip, so the subagent shape (tab-bottom → window-top) has nothing to aim at, and same-row pairs get a shallow U-bridge HANGING BELOW the strip (dip scales with distance, plus a per-sibling step so several children of one parent nest instead of overprinting), while a wrapped strip (`tabs-two-rows`/`tabs-auto-wrap`) falls back to the vertical bezier. + +⚠️ **Desktop only, for a z-index reason**: the overlay is `z-index: 999` and the desktop header is 100, so arcs paint OVER it — which is exactly what lets them touch tab bottoms. Under 1024px mobile.css makes the header `position: fixed; z-index: 1200` and would bury them, and the phone strip is a scroller where both endpoints are rarely on screen at once. Raising the SVG to ~1250 (above the fixed header, below modals at 1300) is the phase-2 option, and needs a real check against the mobile overview and the drawer. + +⚠️ **`data-agent-id="lineage:"` is load-bearing**, not a label: `_applyLineEntrances()` queries paths by that attribute, so tagging them this way is the whole reason the arcs get the draw-in animation AND its negative-`animation-delay` resume across `svg.innerHTML = ''` with zero new animation code. ⚠️ `.session-tabs` is `overflow-x: auto`, so a tab scrolled out of the strip still HAS a rect — one lying over the logo or the header buttons; edges with an endpoint outside the strip are SKIPPED (clamping would point at a tab that is not there), and a passive `scroll` listener re-anchors the rest, since a scroll moves both endpoints without firing any render. The incremental tab render also redraws when `_lineageEdgeCount > 0`: a badge appearing widens a tab and shifts every tab after it. Setting: `sessionLineageLines`, per-device (in `displayKeys`, absent from the `.strict()` `SettingsUpdateSchema`), desktop default ON. Tests: `test/session-lineage-lines.test.ts` (geometry), `test/routes/session-routes-parent-lineage.test.ts` (resolution + reject paths). + ### Full-scrollback replay **Full-scrollback replay** (COD-164/#148, reworked for #205): `GET /api/sessions/:id/terminal?full=1` returns the ENTIRE tmux scrollback (capture-pane `-e -S -` bounded by the configured history limit, explicit `maxBuffer` from the terminal-history config, early byte-cap before normalization, CRLF-normalized for shell panes). On success the capture is returned ALONE (`source='mux-full-history'` — it supersedes the byte buffer; no duplication). The first load OF EACH SESSION per page load requests `full=1` (`_fullHistoryLoaded` Set in app.js — the old one-shot `_initialFullBufferLoad` flag was consumed by whichever tab auto-selected, leaving every other tab one frame of history); later switches keep the cheap `?tail=` visible-frame path. On top of that, scrolling up while already at the TOP of the buffer re-pulls `full=1` on demand (`_maybeRefetchFullHistory`, 4s per-session cooldown, in-flight + tab-switch guards, viewport position held across the replay). The re-pull exists because xterm's buffer is only a WINDOW onto tmux's history and two things shrink it: tmux coalesces bursty output into pane REPAINTS that overwrite rows instead of emitting linefeeds (measured: a 60-line burst added 1 row of browser scrollback and destroyed 34), and a tab switch replays only the visible frame. tmux's own history is intact throughout — the browser just has to ask for it again. On-demand rather than automatic because at a 100k history limit the capture can be megabytes. ⚠️ **The re-pull must never DOWNGRADE the buffer** (#205 round 2): the same reasoning that makes it a win for a shell pane makes it destructive for a repaint-mode CLI pane, where tmux keeps no history of its own (`history_size≈0` measured for a Claude pane) and the capture is roughly ONE frame while xterm may hold hundreds of rows of replayed frames — `_resetTerminalForReplay()` + rewrite then deletes history mid-scroll ("goes back a bit, repeats blocks, gets worse the further up I go"; measured A/B on a live pane: 341 rows → 42 with the guard off). `_replayWouldShrinkBuffer()` (terminal-ui.js) estimates the capture's rendered rows — escape sequences stripped, `capture-pane -J` re-wrapping accounted for — and the pull is skipped when that is more than one screen short of `buffer.active.length`. The one-screen tolerance matters: both sides are estimates (the buffer length counts trailing blank rows), so only a clear downgrade is refused. A refused session joins `_fullHistoryRepullUseless`, raising its cooldown from 4s to 60s so a hollow pane stops re-fetching megabytes on every scroll-up.

Frontend rendering + +### 4.1 Where the code goes + +`_updateConnectionLinesImmediate()` (`subagent-windows.js:242`) is a strict +**batched read → batched write** pass, and it already has an extension point: +ultracode appends its own layer via `_appendUltracodeConnectionLines(svg, rects)` at +the end, sharing the `rects` cache so no layer forces a second reflow. + +Lineage lines follow that exactly: a new module `src/web/public/session-lineage.js` +(load order 15.6, after `ultracode-windows.js`) exporting +`_appendLineageConnectionLines(svg, rects)` onto `CodemanApp.prototype`, called from the +same tail. **The core function keeps ownership of the read/write split**; the new layer +only reads through the shared `rects` map and only appends paths. + +The path math itself lives in `constants.js` as a pure +`computeLineagePath(parentRect, childRect, stripRect, depth)` — same treatment as +`computeTabScrollLeft`, so the geometry is unit-testable without a browser. + +### 4.2 Geometry + +Both endpoints are tabs in one horizontal strip, so the subagent shape (tab-bottom → +window-top) does not apply. Two cases: + +- **Same row** (the normal case): a shallow **U-bridge hanging below the strip**. + `y0 = max(parent.bottom, child.bottom)`, dip + `d = clamp(14 + |x2 - x1| * 0.06, 16, 44) + depth * 6`, path + `M x1 y0 C x1 y0+d, x2 y0+d, x2 y0`. `depth` is the child's index among its + siblings, so several children of one parent **nest** instead of overprinting. +- **Different rows** (`tabs-two-rows` / `tabs-auto-wrap` on desktop): the existing + vertical bezier from parent-bottom-center to child-top-center. + +A small `` at the child end marks direction (an SVG `marker` would need a +`` block and fights `stroke-dasharray`). + +Each path gets `class="connection-line lineage-line"`, `data-parent-tab`, +`data-child-tab`, and `data-agent-id="lineage:"` — that last one is what makes +the existing entrance machinery (`markConnectionLineEntering` / `_applyLineEntrances`, +keyed on `data-agent-id`) work on these lines with **zero** new animation code, +including the negative-`animation-delay` resume across the `svg.innerHTML = ''` rebuild. + +### 4.3 Clipping + +`.session-tabs` is `overflow-x: auto`, so a tab scrolled out of the strip still has a +rect — one that lies outside the strip box and would draw an arc across the logo or the +header buttons. **Skip any edge whose parent or child center falls outside +`stripRect` (4px tolerance).** Skipping is honest; clamping would draw a line to a tab +that is not there. + +### 4.4 Redraw triggers + +`updateConnectionLines()` already coalesces through `scheduleBackground`, so extra +callers are cheap. Needed: + +- `_fullRenderSessionTabs()` — already calls it (app.js:3912). Free. +- `_renderSessionTabsImmediate()` — does **not**. A badge appearing widens a tab and + moves every tab after it, which slides the arcs off their anchors. Add the call, + guarded on `this._lineageEdgeCount > 0` so nobody pays for it without the feature. +- **strip `scroll`** (passive listener on `#sessionTabs`) — the arcs must track the + scroller. This is new; no existing line layer needed it. +- window `resize` — piggyback the throttled handler in `terminal-ui.js:930`. +- `_onSessionCreated` — `markConnectionLineEntering('lineage:' + data.id)` so a new + child draws in **if** the user has a line-entrance theme on (all entrance styles are + `legacy`/off by default, so this is a no-op for an untouched install). + +### 4.5 Styling + +`.connection-line.lineage-line`: violet stroke from a `--lineage-line` token, +`stroke-width: 2`, `dasharray 4 4`, `opacity: .55`, softer glow than the subagent lines +so the two layers read as different things. Trap to respect: the skin block nests under +`html:not([data-skin="og"])`, so a bare `.lineage-line` rule inside it would outrank the +base rule at higher specificity. **Define the color as a token per skin, keep exactly +one `.lineage-line` rule.** Light skins get a darker stroke. + +Optional signal worth having: `.lineage-line--working` (a slow `stroke-dashoffset` +march) only while the **child** session is working, wrapped in +`prefers-reduced-motion: no-preference`. Static otherwise — a permanently marching line +per tab pair is noise and battery. + +### 4.6 Desktop only, and why + +The SVG overlay is `z-index: 999`. On desktop the header is `z-index: 100`, so arcs +paint **over** the header and can touch tab bottoms. Under 1024px `mobile.css` makes the +header `position: fixed; z-index: 1200`, which would **bury** the arcs — and the phone +strip is a scroller where both endpoints are rarely on screen together anyway. So the +layer returns early unless `MobileDetection.getDeviceType() === 'desktop'`. + +Raising the SVG to ~1250 (above the fixed header, below modals at 1300) is a possible +phase 2, but it needs a real check against the mobile overview and the drawer. + +### 4.7 Setting + +`sessionLineageLines`, **per-device** — so it goes in the `displayKeys` set in +`settings-ui.js` and must **not** be added to `SettingsUpdateSchema` (`.strict()`; +sending an undeclared key fails the whole PUT). Rendered as a switch in +App Settings → Appearance, beside the entrance-animation pickers. + +**Default: ON for desktop** (phones never render it). This is the one deliberate +departure from the "new visual surfaces ship OFF" convention — the feature is the +request, and a user with 12 unrelated tabs has a one-click off switch. Flag for the +owner if the convention should win instead. + +## 5. Optional extras (call them separately, none are required) + +1. **Order children after their parent** in `sessionOrder` on create, so arcs stay short + and the strip reads as a tree. Real cost: it renumbers the Alt+N badges and moves + tabs under the user's cursor, so it should be its own toggle, default OFF. +2. **Lineage hover focus**: hovering a tab dims unrelated arcs and brightens its own + subtree. +3. **"Spawned by" in the Session Manager / home rails**, once `parentSessionId` is on + the unified rows. +4. **Inherited tab tint**: children pick up a faded version of the parent's tab color. + +## 6. Tests + +- `test/session-lineage.test.ts` (route-level, `app.inject`): round-trips through + `POST /api/sessions` + `POST /api/quick-start`, header path, body-wins-over-header, + unknown id dropped without failing the spawn, cross-owner parent dropped in + multi-user, field present in `GET /api/sessions` and persisted state. +- `test/session-lineage-lines.test.ts` (jsdom, pure): `computeLineagePath` — same-row U, + wrapped-row bezier, sibling nesting depth, off-strip skip, degenerate zero-width rects. +- Browser check (not in `test:ci`): spawn two workers with a parent, assert two + `path.lineage-line` elements anchored to the right tabs, then scroll the strip and + assert they moved. +- Existing guards that must stay green: `test/mobile-header-buttons-policy.test.ts` + (nothing new on phones), `test/app-settings-structure.test.ts` (the new switch pairs + with its rail section). + +## 7. Skill side (owned by the release session, not this plan) + +One line in the `codeman` skill's §0 preamble covers every spawn recipe: + +```bash +CURL=(curl -sk "${AUTH[@]}" -H "X-Codeman-Parent-Session: $SELF") +``` + +plus a `CODEMAN_PREAMBLE` version bump so stale cached preambles fail loudly instead of +silently spawning unparented workers.

A marker matched instantly, before the command ran + +**You see** `wait.matched:true` within milliseconds, and `wait.snippet` shows your own +command line rather than its output. + +**It means** your keystrokes are output too. A marker that appears verbatim in the line +you typed matches the moment it is typed. + +**Fix** Split the marker so the typed line never contains it: send +`M=DONE; …; echo ${M}_1234\r` and wait on `DONE_1234`. Same symptom, second cause: a +generic marker (`BUILD OK`) matched against stale text, either from `from=buffer` +scanning an earlier run or from tmux replaying old screen content as fresh output on an +attach/resize/redraw. A unique-per-call token (`DONE_$RANDOM`) makes both `from` modes +safe. + +### 6. `jq` parse error instead of an `errorCode` + +**You see** `jq: parse error: Invalid numeric literal…` on every call, no `errorCode` +anywhere. + +**It means** the response is not the envelope. The guards that run before any handler +answer in plain text (full list under [Envelope and errors](#envelope-and-errors)): 401 +Basic auth, 401 hook secret, 403 host not allowed, 403 cross-site blocked, 429 auth rate +limit, 503 too many SSE connections. + +**Fix** Re-run the call with `-w '\n%{http_code}\n'` and no `jq`, then read the status +and the raw body. 401 sends you to [Auth and credentials](#auth-and-credentials); 403 +means a Host/Origin problem, not a bug in your request; 429 means back off for up to 15 +minutes, never retry the credential. + +### 7. `last-response` returns an empty string right after `stop` + +**You see** `.data.text` is `""` on a claude worker whose send-and-wait just returned +`signal:"stop"`. + +**It means** usually nothing is wrong. `text` is read from the transcript file, which is +flushed slightly *after* the `stop` hook fires, so a read taken the instant the wait +returns is too early (verified live: empty on the first call, full prose seconds later). +It is also `""` before the worker's first completed turn, and permanently `""` for +`shell`, `opencode`, `gemini` and `antigravity`, which write no transcript. + +**Fix** Poll it, bounded (10 tries, 1 s apart).

Nothing rejected your request: +`wait:true` (and even an explicit `until=stop`) is accepted because the 400 is about +session **mode**, and the mode really is `claude`. Hooks are written only when Codeman +**creates** the directory; a linked case or a raw `workingDir` gets none (an existing +case that Codeman created earlier keeps the block it was given), see the table under +[Signals by mode](#signals-by-mode). Measured: on a +linked case whose `.claude/settings.local.json` carries env/model/permissions/statusLine +and no `hooks` block, a `wait?until=stop,exit` parked for twelve consecutive 60 s rounds +never resolved although the worker finished its turn. + +**Fix** Check before you rely on `stop`: read `/.claude/settings.local.json` +and look for a `hooks` key whose contents mention `/api/hook-event`. No hooks means +synchronize with a split `wait-output` marker instead (entry 5 has the shape), exactly +as you would for a shell worker.

Workers cannot + read a clock reliably across turns, so prefer a round count. +2. **A heartbeat.** Loop bounded `wait until=stop,exit&timeout=60000` on both workers so + you see each turn boundary, and so peer replies to YOU attach to those results. + Silence across two rounds is a signal (deadlock, below), not patience. +3. **A documented break-glass, and rehearse the order.** ESC first, over HTTP, to end the + current turn: `POST /api/v1/sessions/:id/input` with a bare `\x1b` and NO `\r`. That + survives the write path because it strips only `\r` and `\n` then `trimEnd()`s, and + `0x1b` is not JS whitespace (`tmux-manager.ts:2975`; in-repo proof that ESC is sent + this way: `approval-routes.ts:43`). `POST /api/sessions/:id/send-key` is NOT this: its + allowlist is S-Enter/C-Enter only. THEN send a final message: "stop now, reply with + what you have".

That single fact +drives step 4. + +### 3. Spawn one worker per worktree (API) + +`quick-start` puts a worker in a *case*, not in your worktree. Pointing a session at an +arbitrary path is `POST /api/v1/sessions` with `workingDir`, and it takes **two** calls: +create builds the session but spawns no PTY (`pid` stays null, there is no pane), and +`/interactive` starts the CLI. + +```bash +declare -A WORKER +for s in parser router cache; do + C=$("${CURL[@]}" -X POST "$API/api/v1/sessions" -H 'Content-Type: application/json' \ + --data-binary "$(jq -n --arg d "$WT/$s" --arg n "fix-$s" '{workingDir:$d,mode:"claude",name:$n}')") + # NOTE the shape: .data.session.id here, NOT quick-start's .data.sessionId. + SID=$(jq -r 'if .success then .data.session.id else empty end' <<<"$C") + [ -n "$SID" ] || { jq -c '{error, errorCode}' <<<"$C"; echo "$s: create failed"; continue; } + CREATED+=("$SID") # add it BEFORE starting: a session that failed to start still exists + "${CURL[@]}" -X POST "$API/api/v1/sessions/$SID/interactive" \ + -H 'Content-Type: application/json' -d '{}' | jq -e '.success' >/dev/null \ + || { echo "$s: PTY did not start"; continue; } + WORKER[$s]=$SID +done +``` + +- ⚠️ The capacity failure here is **`OPERATION_FAILED` (422)**, not quick-start's + `SESSION_BUSY` (`session-routes.ts` checks `sessionCapacityMessage` before parsing + the body). Branching only on `SESSION_BUSY` misreads a full server as a bad request. +- ⚠️ Send `/interactive` an empty body. `{"clearBreaker":true}` resets the PTY-exit + circuit breaker, which exists to stop a worker that crashes on every start from being + restarted in a loop; clearing it unasked re-arms that loop. +- Then run **Flow 1's readiness stages 1-3** on each SID. A path claude has never been + run in shows the trust dialog, and typing your task into a dialog answers it blind and + loses the task. Stages 1-3 cost no turn; stage 4, if it fires, costs that worker one + billed turn. + +### 4. Hand out the tasks: markers, not send-and-wait + +⚠️ **These workers have no `stop` and no `blocked`, so send-and-wait cannot tell you a +turn ended.** Codeman writes its hooks block into `/.claude/settings.local.json` +only when it **creates** the directory (quick-start on a case name that does not exist +yet, `POST /api/cases`, clone, docker quickcreate). `POST /api/sessions` runs only +`refreshStaleCodemanHooks()`, which no-ops when there is no Codeman hooks block to +refresh, and linking a folder as a case writes just the name→path registry entry. A +fresh worktree therefore starts hook-less, and stays that way. + +What breaks if you use send-and-wait anyway: `wait:true` is accepted (the 400 is about +*mode*, not about hooks, and these are claude-mode sessions), so the call falls back to +the default set's `idle`, which is a heuristic that flaps mid-turn. You get a "finished" +answer for a turn still running, and `last-response` then hands you the *previous* +turn's text. The contrast is the lesson: a worker in a case Codeman created (Flow 1) has +the hooks, so `stop` there is definitive and free. In a worktree you pay one marker per +worker instead. + +```bash +declare -A TOK +i=0 +for s in "${!WORKER[@]}"; do + i=$((i+1)); TOK[$s]="${RANDOM}_$i" + P="You are in the git worktree $WT/$s on branch fix/$s. Fix the failing suite test/$s.test.ts: make it pass without weakening the assertions, and change no file outside what that fix needs.
