+A read-only window's group overview in the details drawer now draws no write control: the group's name is plain text rather than a rename button, an invited share no longer offers **Remove my Bot**, and a shared room's "Waiting for your approval" card keeps its headline and rows but drops **Approve** and **Reject**, with the host's own sentence in the single `role="status"` line at the top of the page ([#2400](https://github.com/ThinkFlowLab/FlyBot/issues/2400)). A writable window keeps every control unchanged.

 - The "@" reader is shared with the host (`core/src/shared/mentions.js`, bundled into `core/client.js`). #287 added `unmatchedMentions` there (the `@` words that name nobody, used by the host for the face-room hint); `mentionSpans` and what the bubbles draw are unchanged.
 - A friend's Bot settings surface is not the local editor (#160): no rename, avatar editor, model, folder, instructions, Main Bot, Hide, Duplicate, or Delete. The details gear and context menu say **Bot settings**. The menu is Mark as Unread, Bot settings, and Copy conversation ID. Per-friend **Auto-send** and **Remove this Bot** stay on that page (`flybot.bot.details`); Remove closes the overlay so a stale local editor cannot appear. The Bots settings list is local Bots only.
 - A friend's Bot details overview is that compact panel: handle plus `FlyBotDetails` (Auto-send and a muted Remove link), no Browser tab, no Usage / model / folder. Opening the gear uses `remote-bot-settings` (`RemoteBotSettingsSheet`): a bottom sheet on narrow viewports and a centered card from 520px up, with the scrim behind the dialog (`z-index` stacking like `bt-settings` / `bt-mem`) so the sheet stays clickable through enter/leave animations. The surrounding DSH settings-shell chrome (back/title) is not redesigned (#166). The sheet takes focus when it opens (`tabIndex -1`, `preventScroll`), closes on Escape from its own `onKeyDown` as well as `useEscape`, and gives focus back without scrolling; in the tree a friend's `.bt-row-wrap` (row plus gear) shrinks like a plain row (`.bt-tree-item>.bt-row-wrap`), so the gear never overflows the sidebar and focusing it cannot scroll it sideways (#274). On every wide row (own Bots too) the gear's focus and click run `keepSidebarStill`, which puts back any sideways scroll a focus left on the row's ancestors or the page, now and after the settings dialog opened (#421). The Settings nav's last entry reads **Harness settings ↗** with a tooltip saying it opens DeepSeek Harness's own settings in a separate window; FlyBot does not embed or retitle that dialog (#421).
-- An own Bot's settings (`BotSettingsForm`) draw the `flybot.bot.details` entries once, as a titled **Sharing** card right after **Instructions** (`FlyBotDetails` with `wrap` → `Card`), so sharing is not at the end of the page; with no entry there is no card. Bot settings and group settings both end with a **More** card (Duplicate / Delete). A write the host refuses is reported on the dialog's own line under its heading, outside the page's scrolling box: `SettingsDialog` owns the sentence `run` stores, and `.bt-settings-scroll` no longer holds it, so scrolling down to the control that was pressed cannot leave the refusal above the viewport with the switch apparently unmoved ([#2194](https://github.com/ThinkFlowLab/FlyBot/issues/2194)). A window that holds the team read-only says so in that same header: `SettingsDialog` prints the host's own sentence from `roster.readOnly` as a `role="status"` line under the heading and above the refused-write line, so the standing state comes first and the answer to one pressed control sits closest to it, and a blank or missing `readOnly` draws nothing at all (#2199). The details drawer's own Settings view is not that dialog and had no header sentence: it now reads the same window lock (`lockedWindow`, `schedules.js`) and, in a read-only window, draws the host's sentence in the form's place instead of mounting `BotSettingsForm` or `GroupSettingsForm`, so no write control the host would refuse is drawn for a Bot or a group, and a writable window keeps the form unchanged (#2387). A refused write in that view follows the same rule as the dialog (#2385): the `bt-error` line is a sibling above `bt-drawer-body bt-set-body`, not its first child, so a press at the bottom of the group page — Pin, Hide, Make admin, Remove — writes the host's refusal where the press happened instead of at the top of the box it was scrolled past. The drawer's overview view holds the same two rules: its refusal line is a sibling above `bt-drawer-body`, and in a read-only window the Bot's name is plain text with no model, permission or working-folder entry beside it, above a `role="status"` line carrying the host's own sentence, so the overview offers only what the host will not refuse. Tests: `core/test/details-bot-settings-readonly.test.js`, `core/test/details-drawer-refusal-line.test.js`, `core/test/details-overview-readonly.test.js`. The composer card's `:focus-within` border is 55% ink, hover stays 30% (#406). Keyboard Tab order, checked in headless Chrome on a mock bench (#406): sidebar (Search, New…, the Bots, Connect apps, Account) → chat header pill → message box → Add, Dictate, voice → the turn stats; the `shell.overlay` layer (approval cards) comes after the main column in the DOM, and no stop focuses an invisible element. The message box comes before **+** because DSH's DOM puts the input first and FlyBot's CSS only reorders it visually.
+- An own Bot's settings (`BotSettingsForm`) draw the `flybot.bot.details` entries once, as a titled **Sharing** card right after **Instructions** (`FlyBotDetails` with `wrap` → `Card`), so sharing is not at the end of the page; with no entry there is no card. Bot settings and group settings both end with a **More** card (Duplicate / Delete). A write the host refuses is reported on the dialog's own line under its heading, outside the page's scrolling box: `SettingsDialog` owns the sentence `run` stores, and `.bt-settings-scroll` no longer holds it, so scrolling down to the control that was pressed cannot leave the refusal above the viewport with the switch apparently unmoved ([#2194](https://github.com/ThinkFlowLab/FlyBot/issues/2194)). A window that holds the team read-only says so in that same header: `SettingsDialog` prints the host's own sentence from `roster.readOnly` as a `role="status"` line under the heading and above the refused-write line, so the standing state comes first and the answer to one pressed control sits closest to it, and a blank or missing `readOnly` draws nothing at all (#2199). The details drawer's own Settings view is not that dialog and had no header sentence: it now reads the same window lock (`lockedWindow`, `schedules.js`) and, in a read-only window, draws the host's sentence in the form's place instead of mounting `BotSettingsForm` or `GroupSettingsForm`, so no write control the host would refuse is drawn for a Bot or a group, and a writable window keeps the form unchanged (#2387). A refused write in that view follows the same rule as the dialog (#2385): the `bt-error` line is a sibling above `bt-drawer-body bt-set-body`, not its first child, so a press at the bottom of the group page — Pin, Hide, Make admin, Remove — writes the host's refusal where the press happened instead of at the top of the box it was scrolled past. The drawer's overview view holds the same two rules: its refusal line is a sibling above `bt-drawer-body`, and in a read-only window the Bot's name is plain text with no model, permission or working-folder entry beside it, above a `role="status"` line carrying the host's own sentence, so the overview offers only what the host will not refuse. A group's overview follows it (#2391 left it to P-544): the name is plain text with no rename control, `Remove my Bot` is gone, and the host's one sentence sits above the reads — a shared room's approval card keeps its headline and rows and drops its decisions — while a writable window keeps every control. Tests: `core/test/details-bot-settings-readonly.test.js`, `core/test/details-drawer-refusal-line.test.js`, `core/test/details-overview-readonly.test.js`, `core/test/details-group-overview-readonly.test.js`. The composer card's `:focus-within` border is 55% ink, hover stays 30% (#406). Keyboard Tab order, checked in headless Chrome on a mock bench (#406): sidebar (Search, New…, the Bots, Connect apps, Account) → chat header pill → message box → Add, Dictate, voice → the turn stats; the `shell.overlay` layer (approval cards) comes after the main column in the DOM, and no stop focuses an invisible element. The message box comes before **+** because DSH's DOM puts the input first and FlyBot's CSS only reorders it visually.
 - Every listed Bot row in wide sidebar mode is a `bt-row-wrap`: the session `bt-row` and a sibling gear (`bt-row-settings`, hover/focus) that opens Edit Bot for an own Bot or Bot settings for a friend's (#166, #276).
 - The Session header is the shell's own: FlyBot registers the Bot pill in `conversation.session.header.utilities` rather than claiming the single `conversation.session.header` slot, so the seats that header renders — the lineage title and `conversation.session.header.actions`, where `@deepseek-ai/ui-subagent` puts the subagent catalog — keep rendering (#803). The floating header style FlyBot used to draw over the Session header is gone.
 - What the pill does to the page is not in the pill and not in a seat of its own (#803). The shell draws `.utilities` — and the pill with it — only while its chrome shows, which a Session without a first message hides, so a side effect parked in the pill stops there: the friend's empty-chat hint, `body[data-bt-friend-chat]`, the `Message {name}` composer label, the visit ledger, `body[data-bt-room]` and the face-room `@` filter. `installHeaderEffects` (`src/client/header-effects.js`) is installed once from `apply` and keeps them on the Session in the main view. It carries no React, and each effect has its own dependency key: the sessions list answers before the roster, so a single "did the Session change" guard would drop a friend's flags on the first pass, while `beginVisit`/`endVisit` keyed on more than the Session would open a second visit for a chat that was only just opened. `test/header-effects.test.js` drives those transitions on jsdom; `test/header-slot.test.js` pins that no such effect runs in `HeaderPill` and that FlyBot claims no other header seat.
