They now belong to the subagent: the transcript projection keeps the session's own rows as the conversation and each subagent's rows apart, keyed by the agent id its roster entry already carries, folded on their own. Desktop: a subagent's rows open in a section under the roster row that names it, from that agent's roster entry, and are windowed like any other rows. A subagent no loaded roster names opens where its first row happened, inside the section of the agent that spawned it or in the conversation. Its edits still count in the turn they were made, and revealing one opens the sections around it. Mobile shows the conversation, with each spawn's roster line. Worker reads and structured terminal reads serve the worker's own rows. Removes what the move makes redundant: the per-row caption and its copy, the producer check in the tool fold and the turn answer, the per-agent frontier interleaved in the conversation, worker-text subagent tags, and the agent id on worker-read messages. * refactor(native-chat): a diff target names the sections its row sits in Revealing a subagent's edit opens the sections around it from the target the rollup already holds, instead of looking the row up at click time. The section head keeps to the agent's name and dot; its state in words stays on the roster entry. The worker page test stubs the host through its module rather than a cast. * fix(native-chat): a working subagent's section is open; a worker page windows its own rows A subagent's section is open while its agent works and closes once it settles, the way the turn's own live run does; a section the reader opened or closed by hand keeps that choice. A subagent another subagent spawned opens inside that one's section, so a working grandchild shows inside its working parent. Openness is derived from the roster's state and the reader's choices; nothing stores an automatic open. A worker page is now the newest page of the worker's own rows. The host windows the read over them before the limit, so a subagent's burst can no longer crowd the worker's rows off the page, and "older" still means older worker rows. The scope is an in-process argument of the host's history read; no wire request carries it. * fix(native-chat): a subagent section head names the turn it sits in, for the outline rail * fix(native-chat): a subagent section's rows sit in the turn the section is shown in, for the outline rail A background subagent's rows written during a later turn carried that later turn onto their slots, so scrolling through its section lit the later turn's rail tick and then snapped back. The rollup still counts each edit in the turn it was made; only the slot, which the rail reads, takes the shown turn. * fix(mobile): Load earlier reads past pages that hold only a subagent's rows Mobile draws only the session's own rows, so an older page made entirely of a subagent's rows landed as nothing: the reader tapped Load earlier, saw the spinner, and got the same transcript back. One load now reads on (up to 8 pages) until a page holds a row of the session's own, then applies the pages in order. * test(mobile): stub the RPC client the way the other structured-session hook tests do * perf(native-chat): order subagent rows for the changed-files rollup once per change to them The rollup flattened and re-sorted every subagent row on each update, including every token the parent streamed. The ordering now keys on the projection's subagent rows, which keep their identity while only the conversation changes. * refactor(native-chat): order subagent rows in the sections hook, keeping the list under its line limit * fix(mobile): a transcript whose newest page is only a subagent's rows reads back on its own Opened while a subagent is busy, the newest page can hold nothing but that subagent's rows. Mobile draws none of them, so the reader saw an empty chat with a Load earlier button, and an empty list cannot be scrolled to page. The hook now reads back once from each such head, and the read runs on to the session's own rows. * fix(native-chat): count the live window in the session's own rows, so a subagent's burst keeps its roster The live window kept the newest 1,024 rows of every agent. A subagent writing more than that trimmed its own spawn's roster row and the prompt, and its section fell back to a closed, unnamed header. The window now keeps the newest 1,024 of the session's own rows and everything after, with an 8,192-row cap on every agent's rows as the memory backstop. A transcript with no subagent rows trims exactly as before. * fix(agent-session): window history pages by the session's own rows, with a subagent's rows riding along A history page held the newest 200 rows of every agent, so a subagent's burst could fill a page on its own: the phone opened on an empty chat and "Load earlier" landed nothing. A page now starts at the oldest of the newest `limit` rows of the session's own and serves every row from there, so the subagent's rows come with the conversation they happened in. The page stays contiguous, the cursor still names its first row, and the byte bound still applies. A transcript with no subagent rows gets the same pages as before. Clients already take a page larger than its limit: both reducers raise their retained window to the page's size. The mobile read-on and read-back stay for older hosts. * test(agent-session): a page reaches back to the start rather than leaving a subagent-only page * fix(native-chat): an own-row trim takes a trimmed roster's subagent rows with it The live window trimmed to just after the own row it dropped, so a subagent whose roster row went kept its rows at the top as an unnamed section until the parent wrote again. Trim to the oldest own row kept instead; it still fires only once an own row passes the limit, so a paged-in run of subagent rows at the head stays until then. With no subagent rows nothing changes. * perf(native-chat): cap the live window at 4,096 rows, bounding each delta's re-derivation Every live batch re-derives the transcript over every retained row. On the largest real window (7,374 rows) that cost 7-8 ms a delta on desktop against 0.6 ms at the old 1,024-row window, and held about 26 MB of row content. 4,096 halves both. The most rows any local journal puts between a roster and its subagent's last row, with the parent inside its own-row limit, is 3,005, so no observed subagent loses its roster to the lower cap. * fix(native-chat): a subagent section opens only while its roster is the running scope's live frontier A section used to open whenever its roster said the subagent was working, anywhere in the transcript and whether or not the session was running, so a background subagent's section stayed open and grew mid-transcript while the parent moved on. It now opens by default only while the session runs and the roster row naming the subagent is the newest thing the parent produced, user rows aside. Newer parent output closes it even while the subagent still works; the roster row keeps showing that live state. A subagent still working is a running scope of its own for the sections it spawned; a settled one closes its scope. Derived every render, no latch; the reader's own open or close still wins. * fix(native-chat): name a subagent's section from a client roster the window never trims A section took its name and state from a roster row in the loaded window. Once a burst trimmed that row, or the row sat on an older page, the section fell back to an unnamed, closed "Subagent" header. The shared reducer now keeps a roster keyed by agent id, folded from every roster row and revision the client receives: pages, older pages and live batches, including revisions of roster rows outside the window, which live batches already carry. The first roster naming an agent wins and its revisions update it; a removed roster row drops its entries; it is rebuilt on every page that replaces the window and bounded to 512 agents. Sections take their name, state and live-frontier place from it; placement stays under the loaded roster row, else at the section's first loaded row. Only a subagent no roster ever named stays unnamed. * feat(agent-session): a history page names the subagents whose roster row is older than it A page is a contiguous run of the journal whose older-page cursor is its first item, so it cannot pull an older roster row in without skipping the rows between. When a page held a subagent's rows but not the roster row naming it (about 11% of the moments a reader could open a session on local journals), that subagent drew as an unnamed "Subagent" header. History and hydration pages now carry an optional `subagentRoster`: the first roster entry naming each subagent whose rows are on the page and whose roster row is not, with the row's id, sequence and revision; bounded to 64 entries and 16 KB. Items and cursor are unchanged. The client seeds its roster from it. Rule 1 in docs/reference/remote-wire-compatibility.md: an optional field on an existing frame, no capability gate. An older client ignores it (the released reducer reads a page with it exactly as one without); against an older host the field is absent and the section falls back to an unnamed header. * Revert "fix(native-chat): an own-row trim takes a trimmed roster's subagent rows with it" This reverts commit 22078656b2. Its only purpose was to stop a subagent whose roster row an own-row trim had dropped from showing at the head of the window as an unnamed section. The client roster now names that section whatever the window holds, so the cut is back at just after the own row the limit passes. The retention test that pinned the unnamed-section case now asserts the section at the head keeps its name. * chore(native-chat): state the retention limits' own reasons, now that no name depends on the window Own-row retention keeps the conversation a reader sees from being crowded out by rows drawn as a one-row section on desktop and not at all on mobile; the every-agent cap bounds memory and each live delta's re-derivation. Neither is about keeping a roster row loaded any more. * fix(native-chat): hold the roster fold's draft map where type narrowing can see closure writes * fix(native-chat): a roster row's newer revision replaces it in the client roster too A revision that stops naming an agent (the host drops an entry it learns is not a subagent, or re-keys a provisional one) left the client roster holding the old entry, often still "working", with nothing to re-derive it. The section then read as working forever and could auto-open, while a fresh read of the same journal left it unnamed. The fold now drops an entry when a newer revision of the row that named it no longer does, before any roster takes it over. * fix(native-chat): a parent's spawn and wait calls keep the subagent they name open A subagent section auto-opened only while its roster row was the running session's newest row, so any later row closed it: a Codex wait on the agent, or the parent's text before its next spawn call. Now a row that is part of delegating to a subagent keeps that subagent open: - a Codex collab call (spawn, wait, resume, message, close) opens each agent its receiver thread ids name; one naming none is ordinary output; - a Claude spawn call names no agent, so it counts toward the roster announcing it; - a roster row at the frontier opens its most recently added agent, not all of them. A roster or call naming only agents one subagent spawned is that subagent's output, so a grandchild's roster, which the host journals as the session's row, no longer closes the spawner's section. * fix(native-chat): a parent's call right after the roster closes its subagent's section A parent's tool calls after a roster row fold into the tool run drawn above the roster, so the roster stayed the newest drawn row and its section stayed open while the parent was already reading or running commands. The fold now records the newest journal position among the rows it merged, and the live frontier orders rows by that newest part. The layout is unchanged. A spawn call folded there still counts as part of the roster announcing it. * fix(native-chat): a Codex call naming several subagents delegates to the first A Codex collab call that names several agents opened every one of their sections. It now counts as delegating to the first agent it names, so one section opens, the same as a call naming one agent. * fix(native-chat): closing a roster's list closes the sections under it Collapsing a roster row's list of subagents left their open sections drawn, so the section's own head became the only way to close them. And the list's open state lived in the row, so a row the window unmounted came back collapsed. The transcript now holds each roster list's open state beside the section choices. A closed list hides every section it anchors; each section keeps its own open or closed choice for when the list reopens. With no choice from the reader, a list is open while a section under it is open. Closing a section from its entry keeps the list open, and revealing a subagent's edit opens the list it sits under. * perf(native-chat): a reveal finds the roster lists it opens with one set lookup per entry * fix(native-chat): a subagent's roster entry heads its own rows An open section drew the agent's name twice: its entry in the roster's list, then a separate section head above its rows. The entry is now the head. The roster row draws its entries through the first open one, that agent's rows follow, then the entries after it, each run in its own windowed slot. A section no loaded roster row holds (an older page, a grandchild, an unnamed agent) keeps its own head. A roster list is open while the live frontier or a reader's choice is on one of its agents, unless the reader closed the list, so closing an agent from its entry no longer needs to pin the list open. The section emitter moves to its own module, and the trailing-run predicates it shares with the slot builder to theirs, to keep the slot builder under its line limit. * fix(native-chat): the entries after an open subagent's rows set in its roster's type The roster row's list inherits the system row's small muted type; the entries that follow an open section sit outside that row, so they now carry the same type. * docs(native-chat): a current host can also serve a page of only a subagent's rows A page is bounded by bytes after it is windowed by the session's own rows, so a burst that fills the bound yields a page, or an opening page, with none of the session's own rows. Mobile's read-on and read-back therefore serve current hosts too, not only older ones; the comments said otherwise. The retention comment still described a closed section as a row of its own; it now sits behind its roster entry. * fix(native-chat): a section's prose keeps its copy/timestamp controls inside the section An assistant row's hover controls (copy, scroll-to-top, timestamp) hang 20px below the row into the gap before the next one (`-mb-5`). Inside a subagent's section that put them below the section's left border, and on the section's last row they touched the parent's next row with no gap. Inside a section the controls now stay in flow, so the border covers them and the next row sits the normal gap below. The row-height estimate reserves the same 20px for a section's prose so windowing does not jump on measure. * test(agent-session): state each appended row's turn scope, as the journal now requires * refactor(native-chat): the client's journal retention policy lives in its own module	2026-09-29 23:47:02 -07:00
