fix(readmymind): style the modal footer, point the empty-result copy at the steer note

The footer buttons shipped with class="btn btn-secondary/primary", but no
.btn or .btn-secondary rule exists in this codebase, so all four rendered
as unstyled UA buttons. Moved them to the btn-toolbar convention every
other modal footer uses, with a scoped flex-row footer rule (btn-toolbar
is display:flex, block-level) mirroring the runSummaryModal footer.

Send's accent needs a (0,4,0) re-assert: the skin block's bare
.btn-toolbar rule is (0,2,1) under html:not([data-skin="og"]) and beats
.btn-toolbar.btn-primary (0,2,0), the same specificity trap CLAUDE.md
documents for mobile.css. Scoped to this modal; the repo-wide greying of
btn-primary on non-OG skins is pre-existing and left as a design call.

The empty-result copy now points at the steer note sitting right below
it ("Add a steer note and Rethink to try again"), zh-CN updated.

Verified with the steer E2E (still green) plus desktop, phone (390px),
and error-phase screenshots; static guards extended to pin the footer
convention and the accent re-assert.

+- Session rows that name their worktree, a shell keyboard bar for phones, App Settings as one scrolling document, and the Read My Mind modal on phones.
+  - **#265 / #266**: a past session whose directory no longer exists used to report
+    `$HOME` as its working directory, because history rows reconstructed a path by
+    stat-walking the filesystem and fell back to `$HOME` when nothing resolved.
+    Deleting a worktree is the normal end of its life, so every past worktree
+    session collapsed onto the same indistinguishable row. History rows now read
+    the literal `cwd` Claude Code stamps on its own records, out of buffers the
+    scanner had already loaded, so it costs no extra file reads and survives the
+    directory being removed. Sessions that ran in a worktree also carry a
+    `⑂ name · branch` pill in the Resume list and the Cmd+K session manager, and
+    both are searchable by worktree name and branch. Measured on a real install:
+    the cwd was recoverable for 215 of 216 transcripts, 212 of them from the first
+    16KB, and 28 rows that previously read `$HOME` now report their real path.
+    Reported and implemented by @jordan8037310.
+  - **#262**: a shell session now gets its own mobile accessory bar
+    (`Ctrl · Esc · Tab · ↑ · ↓ · ← · → · Paste · ⌄`), with Ctrl as a one-shot
+    modifier: tap it, and the next character goes out as its control byte. That
+    puts Ctrl+C/D/Z/R/L/A/E/W/U/K on a nine-button bar without a button per chord.
+    The modifier is applied on the CJK input path too, where the textarea owns the
+    keyboard and an armed modifier could previously neither fire nor be spent, so
+    it survived until a later keystroke and turned that one into a control byte.
+    Agent sessions keep the existing bar unchanged. Proposed by @DodgyBadger.
+  - **#257**: with several tabs open on a phone, the rightmost ones could not be
+    reached. Selecting a tab never scrolled the strip, and every ambient rebuild
+    reset `scrollLeft` to 0, so a strip the user had just swiped snapped back a
+    moment later. Reported by @DodgyBadger.
+  - **App Settings** is now a left rail acting as a table of contents over one
+    scrolling document instead of 8 tabs that wrapped onto two rows. Nine sections,
+    all mounted at once, so find-in-page works across the whole thing. The model
+    controls stop contradicting each other: the base model lives on cards and "1M
+    context window" is a switch that composes onto it, retiring the old pair of
+    settings that each claimed precedence over the other.
+  - **Read My Mind** suggestions beyond the first are no longer discarded. The
+    alternates render as tappable rows with their kind badge, tapping one swaps it
+    into the editable field without losing an in-progress edit, and Rethink now
+    records the whole shown set as rejected. The modal is sized for phones and
+    reachable from the phone keyboard bar.
+  - The desktop welcome screen carries the open tabs as a rail docked to the left
+    edge, with created and last-active stamps refreshed in place.
+  - The README now documents cloning a GitHub repository straight into a case
+    (**Add Case → Clone Repo**), which shipped in 1.16.2 but was only described in
+    the architecture docs.
+
+- 5d42f64: Home screen: make the past-conversation list usable, and let search find past sessions.
+  - **#260**: "Resume Conversation" showed 4 rows and then dumped every remaining
+    one into a fixed 240px box, with no ordering or filtering. The list now opens
+    with 10 rows, "Show more"/"Show less" grows and shrinks the box itself (the
+    height cap is class-driven instead of fixed), and the header carries a filter
+    box (matches name, folder, `#case` label and the conversation's prompts), a
+    sort control (recent / name A–Z / folder A–Z, pinned rows still first) and a
+    shown-of-total count. Filtering implies expansion, so every match is visible.
+  - **#261**: the search box could not match a past project by folder name: its
+    session corpus was the live in-memory map, while past sessions come from
+    `/api/sessions/unified`. Search now also harvests a bounded snapshot of that
+    unified list, refreshed OUTSIDE the request path (published by
+    `/api/sessions/unified`, plus a fire-and-forget rebuild when stale), so the
+    search path keeps its no-filesystem-reads property. Results for a closed
+    session resume the conversation instead of trying to select a tab that no
+    longer exists, and are badged `RESUME`. In multi-user mode the snapshot is
+    re-scoped per row on read, matching what `/api/sessions/unified` exposes.

+### Patch Changes
+
+- Clone a Git repository straight into a case, predict the prompt you were about to type, and point a session at a separate Claude account.
+
+  **Clone Repo (#251, proposed by @DodgyBadger in #236)**: Add Case gains a **Clone Repo** tab that clones a repository into `codeman-cases/<name>` and registers it as a normal local case. A live verdict under the URL field answers, while you type, whether the URL is cloneable without credentials, what its default branch is, and which branches and tags exist (`POST /api/cases/clone-preflight` behind `git ls-remote --symref`). The case name fills in from the parsed repo, refs come from the remote as a datalist, shallow clone is optional, and a Brain picker (installed CLIs only) points the Run button at the agent you chose. Starting a session stays opt-in, and the tab hides itself when the server has no `git`.
+
+  **Every settings writer now refuses to write through a symlink (from the #251 review, affects existing cases too)**: case contents can be foreign, and a repository can ship `.claude` or `.claude/settings.local.json` as a symlink pointing anywhere on this machine. Since `writeFile` follows links, a scaffold write could land outside the case, up to and including replacing your own `~/.claude/settings.json`. All seven writers that touch a case's `settings.local.json` (`writeHooksConfig`, `ensureCodemanHooks`, `refreshStaleCodemanHooks`, `updateCaseModel`, `updateCaseEnvVars`, `stripCaseEnvKeys`, `applyStatusLineConfig`) now go through one `withSafeSettingsWrite()` gate that runs the symlink check inside the per-path settings lock. A refusal is a warning rather than a throw, so hooks degrade to output-based idle detection instead of failing the operation. If you have deliberately symlinked a case's `.claude` or its `settings.local.json`, Codeman will now decline to write there and say so; replace the link with a real file or directory to get hooks, model and statusLine writes back.
+
+  The clone endpoint (`POST /api/cases/clone`) is synchronous by design: no job store, no polling, bounded by `GIT_CLONE_TIMEOUT_MS` (default 5 minutes). Security decisions live in a pure half of `src/git-clone.ts` so each is unit-testable without spawning anything: `<name>::<payload>` transports are refused as a family (any of them dispatches to a `git-remote-<name>` helper, which turns a clone into arbitrary command execution), a leading `-` is refused and `--` precedes every operand, argv arrays are used rather than a shell, URLs carrying credentials are refused, and non-interactive means more than `GIT_TERMINAL_PROMPT=0` (empty `GIT_ASKPASS`/`SSH_ASKPASS`, `SSH_ASKPASS_REQUIRE=never`, empty `DISPLAY`, `GCM_INTERACTIVE=never`, `ssh -oBatchMode=yes`), since with the request held open any one of those left open is a hang instead of an error. Timeouts signal the process group, because `git clone` fans out into `git-remote-https`/`index-pack` and SIGTERM to the parent alone can leave the fetch running. Repository contents beat scaffolding: an existing `CLAUDE.md` is kept, hooks merge into whatever `.claude/settings.local.json` the repo shipped, and a repo shipping its own `.claude/settings*` is reported back as a warning, because those hooks run locally as soon as a session starts.
+
+  **Read My Mind phase 2 (#256)**: phase 1 (1.16.1) gave each case an intent profile; this turns it into the feature as pitched. Press 🧠 on a Claude session and Codeman predicts the prompt you were about to type, from your stated goals, your recent prompts in your own voice, the last assistant reply, tool activity, git state, away context, sibling sessions, and any dialog the session is waiting on. The context assembler is pure and budgeted with trust tiers, so user-stated intent outranks observed content and terminal output alone can never justify a suggestion. One shot at opus (`readMyMindModel` overrides), a strict JSON contract, and 1 to 3 suggestions typed continue / verify / redirect. The modal keeps the suggestion editable: Send, Insert (drops it on the composer without Enter), Rethink (rejections feed back into the next attempt), Dismiss. Nothing is ever auto-sent, the click is the boundary. Opt-in via App Settings, Panels (synced, default OFF), desktop header only. Agents get the same verb through the Codeman skill (`POST /api/sessions/:id/readmymind`).
+
+  **Per-session `CLAUDE_CONFIG_DIR` (#255, designed and specified by @jordan8037310)**: `schemas.ts` gains an exact-key tier (`ALLOWED_ENV_KEYS`) beside `ALLOWED_ENV_PREFIXES`, admitting `CLAUDE_CONFIG_DIR` so a case can run on a separate Claude subscription (client-billed accounts). Exact match only: other `CLAUDE_*` keys and near misses like `CLAUDE_CONFIG_DIR_EXTRA` stay rejected, blocked keys stay blocked. The key survives `getEnvOverridesForPersist()` because it is a path rather than a secret, and dropping it would silently switch a rebuilt session back to the default account after a reboot. Caveat worth knowing: a relocated config dir writes transcripts outside `~/.claude/projects`, so the response viewer, subagent windows, ultracode panel and Read My Mind go blind for that session unless `projects` is symlinked back into the shared tree.

 **Approvals Inbox** (cross-session queue of prompts waiting on a human; `approvalsInboxEnabled`, SYNCED, default OFF: every surface is opt-in; only the store and answer endpoints run regardless, so flipping it ON shows anything already pending): `web/approval-inbox.ts` is a `sessionWaits`-style singleton fed by `/api/hook-event`, holding at most ONE item per session (a new prompt supersedes), claude-mode only, in-memory. Cards are answered via `POST /api/approvals/:id/answer`, which sends a digit / Esc / idle-prompt text through `writeViaMux` (menu answers never carry `\r`). ⚠️ `option` digits are accepted ONLY when they match options parsed from the captured pane frame, and the answer path RE-CAPTURES the pane first (a dialog that no longer parses on screen means the keystroke would land in the composer, so refuse with 409). ⚠️ Resolution on the heuristic `working` signal is restricted to `idle` items; permission/question items clear only on definitive signals (`stop`, `elicitation_complete`/`elicitation_response`, exit/delete, answer, supersede, 12h TTL). The frontend seeds from `GET /api/approvals` in `handleInit` (which is what makes tab alerts survive reloads), but only with the setting ON; push Approve/Deny buttons are also gated on it (`sendPushNotifications` strips `actions`/`approvalId` when OFF) and are answered from `sw.js` directly so they work with no tab open.

 **Clone a repository as a case** (issue #236, Add Case → **Clone Repo**): `POST /api/cases/clone` clones a public repo into the caller's case space synchronously (request held open, bounded by `GIT_CLONE_TIMEOUT_MS`, no job store); `POST /api/cases/clone-preflight` reports whether the URL can be cloned anonymously plus its real branches/tags.

Dashboards are **proxied through Codeman's own origin** by default, because a direct iframe fails three ways at once: prod is HTTPS so `http://` targets are blocked as mixed content, many dashboards send `X-Frame-Options: DENY`, and our own `default-src 'self'` CSP blocks cross-origin frames. Proxying leaves the prod CSP unchanged (`/webview/...` is `'self'`). ⚠️ The proxy is **NOT an API surface**: it authenticates on an in-memory capability in the path and is correspondingly exempt from the cookie + Origin checks; that exemption is fenced to safe methods and non-`/api` paths and is pinned by `test/webview-auth-exemption.test.ts`. ⚠️ Iframes omit `allow-same-origin` unless a dashboard is explicitly marked `trusted`, and `Authorization`/`codeman_session` are stripped upstream in **both** modes so `CODEMAN_PASSWORD` cannot leak. ⚠️ A sandboxed frame is **opaque-origin**, which breaks two things `curl` can never reproduce: its runtime-built root-absolute URLs escape `<base>` (fixed by an injected `runtimeUrlShim()`), and its same-host `fetch`/XHR are CORS-checked with `Origin: null` (fixed by `buildProxyCorsHeaders()` plus exempting the proxy from the global `OPTIONS`-204 short-circuit in `registerSecurityHeaders`).

+**Mobile tab strip scrolling** (issue #257): under 768px the tab strip is a horizontal scroller (desktop wraps to a second row instead), so the active tab can sit off-screen. Three rules keep it reachable and they only work together: `_updateActiveTabImmediate()` scrolls the selected tab into view via `computeTabScrollLeft()` (pure, in constants.js) using **rect math on the strip's own `scrollLeft`**, never `scrollIntoView()`, which would also scroll the document under a fixed header; `_fullRenderSessionTabs()` **restores `scrollLeft`** across the `innerHTML` rebuild, since ambient rebuilds (a task badge appearing, a session created elsewhere) otherwise snap a mid-swipe strip back to 0; and it re-reveals the active tab **only when it changed** (`_lastRenderedActiveTabId`), so browsing the far end of the strip is not undone by background renders. ⚠️ Mobile no longer hoists the active session to the front of the strip: that reordering ran on full renders only, so tab order flipped depending on which render path fired, and it renumbered the Alt+N badges. Scroll-into-view replaces it; do not reintroduce it.

 **Phone overview home screen** (`mobile-overview.js`, phones only, per-device `mobileOverviewEnabled`, default ON): under 430px the "C" logo shows a session overview (NEEDS YOU / CURRENT SESSIONS / PAST SESSIONS) instead of the welcome overlay; tablet and desktop are unchanged. The branch lives in `showWelcome()`/`hideWelcome()` (terminal-ui.js) behind `shouldUseMobileOverview()`, which is **width-driven** (`getDeviceType() === 'mobile'`) because this is a layout decision, unlike the settings namespace which stays handheld-based. ⚠️ The container ships with the `hidden` attribute and only this module removes it: never give `.mobile-overview` a bare `display` rule, since desktop does not load `mobile.css` (`media="(max-width: 1023px)"`) and would then render it unstyled. Live re-renders ride on the tail of `_renderSessionTabsImmediate()` (every state change it needs already funnels there); PAST rows come from one `_fetchUnifiedSessions(60)` per home-screen visit and resume through the shared `resumeHistorySession()`, so they behave exactly like the welcome screen's Resume list. ⚠️ Two things must stay in lockstep with surfaces outside this module, because divergence reads as a bug rather than a style: the split Run button carries the **toolbar's own classes** (`btn-toolbar btn-run mode-<backend>` / `btn-run-gear`) so the per-backend gradient and the light-skin overrides apply unchanged (mobile.css must therefore set no `background`/`color` on it), and row status uses the **session-tab language** (green dot when fine, `pulse` while working, yellow blinking row when waiting for input, red blinking row when a question is pending, mirroring `tab-alert-idle`/`tab-alert-action`). The picker mirrors the toolbar run-mode menu (`setRunMode()` + `run()`, `openWebviewFromMenu()` for saved dashboards) and deliberately omits its Recent-Sessions block, since PAST SESSIONS is that. Status pills carry `data-i18n-skip` (generic words like "idle" collide with state strings elsewhere).
 
-**Desktop home tab column** (`home-sessions.js`, desktop only): the welcome overlay centers ~560px of content in a ~1400px window, so its left gutter is dead space; it now carries the open tabs as a vertical list. Rows are in **tab order**, not sorted by urgency like the phone overview, because the row badges are the Alt+1..9 indices. State classification is REUSED from mobile-overview.js (`_mobileOverviewState`/`_mobileOverviewCaseFor`), which is why the module loads after it. ⚠️ The column is `position: absolute` so the centered content never moves, which is exactly why it needs a **width gate in two places** — `HOME_SESSIONS_MIN_WIDTH` (1180) in the JS plus a `max-width: 1179px` media query as the backstop for a resize that outruns the matchMedia listener; drift between them means a column overlapping the search panel, and `test/home-sessions.test.ts` pins them equal. ⚠️ `.home-sessions` is `display: flex`, so `[hidden]` must be re-asserted as `display: none` or the module's only visibility lever does nothing. Working state is deliberately byte-identical to the phone's: pulsing green dot + the `tab-load-spin` ring reused from the tab strip + the same green halo (added to `.mobile-overview-dot--working` at the same time), so "working" reads the same on every surface. Live re-renders ride the tail of `_renderSessionTabsImmediate()` alongside the phone overview.
+**Desktop home tab rail** (`home-sessions.js`, desktop only): the welcome overlay centers ~560px of content in a ~1400px window, so its left gutter is dead space; it carries the open tabs as a rail **docked flush to the left edge, full height** (a vertically centered card floating mid-gutter read as debris). Rows are in **tab order**, not sorted by urgency like the phone overview, because the row badges are the Alt+1..9 indices, and each carries **created / last-active** stamps. State classification is REUSED from mobile-overview.js (`_mobileOverviewState`/`_mobileOverviewCaseFor`), which is why the module loads after it. ⚠️ The rail is `position: absolute` so the centered content never moves, which is exactly why it needs a **width gate in two places** — `HOME_SESSIONS_MIN_WIDTH` (1180) in the JS plus a `max-width: 1179px` media query as the backstop for a resize that outruns the matchMedia listener; drift between them means a rail overlapping the search panel, and `test/home-sessions.test.ts` pins them equal. ⚠️ `.home-sessions` is `display: flex`, so `[hidden]` must be re-asserted as `display: none` or the module's only visibility lever does nothing. ⚠️ Size scales with the viewport off **one knob**: `width: clamp(250px, 19vw, 430px)` plus a fluid `font-size` on `.home-sessions`, with every child sized in `em` — reintroducing `rem`/px type inside the block silently breaks the scaling, and widening the clamp past the gutter reintroduces the overlap the gate exists to prevent. The age stamps are refreshed **in place** by a 20s clock (`_tickHomeSessionsTimes()`, disarmed in `hideHomeSessions()`), never by re-rendering, which would restart every row's blink and working ring. Working state is deliberately byte-identical to the phone's: pulsing green dot + the `tab-load-spin` ring reused from the tab strip + the same green halo (added to `.mobile-overview-dot--working` at the same time), so "working" reads the same on every surface; **idle** is deliberately NOT that green — dot and pill mix toward `--text-muted` so a glance separates running from sitting. Live re-renders ride the tail of `_renderSessionTabsImmediate()` alongside the phone overview.
+
+**Welcome "Resume Conversation" list** (terminal-ui.js): `loadHistorySessions()` fetches once and caches the corpus on `_historyAll`/`_historyCases`; every subsequent view (filter box, sort select, expand, the periodic refresh in panels-ui.js) goes through `_renderHistoryList()`, so never append rows to `#historyList` directly or re-fetch to re-sort. ⚠️ The box height is **class-driven**: expanding the list without `.history-list.expanded` leaves the collapsed `max-height` in place and just deepens a scroll well, which is the bug #260 reported (35 sessions in a ~4-row box). ⚠️ The A–Z sort keys off `_historyRowLabel()`, the SAME string the row renders (`name || firstPrompt || path`), most rows are transcript-backed and have no session name, so sorting on `name` alone silently does nothing. ⚠️ A filter implies expansion, and `_renderSearch()` hides `#historyHeader` (title + controls) as one unit while a search is active. Tests: `test/history-list-controls.test.ts`.
 
 **Command palette + shortcut registry**: `Ctrl/Cmd/Alt+K` opens the session palette; shortcuts live in a rebindable registry (`DEFAULT_SHORTCUTS`/`getShortcutRegistry()`/`matchesShortcutEvent()` in app.js, overrides in `settings.shortcutOverrides`). ⚠️ Palette-chord keys must ALSO be swallowed in `attachCustomKeyEventHandler` (terminal-ui.js) or xterm writes the control byte (0x0B) into the PTY. ⚠️ `saveAppSettings()` rebuilds settings from the DOM, so keys edited elsewhere (`shortcutOverrides`, `showTokenCount`, `showCost`) need explicit `_prev` carry-over. ⚠️ **Smart copy (`Ctrl+C`)** lives in that same handler: with a selection it copies, with none it must `return true` **without** `preventDefault()` or the interrupt is lost. `copyTerminalSelection` is deliberately absent from `SHORTCUT_ACTIONS` because the generic capture loop preventDefaults every match it dispatches. → [architecture-invariants#command-palette-and-shortcut-registry](docs/architecture-invariants.md#command-palette-and-shortcut-registry)
 
 **Per-device vs synced settings**: the `displayKeys` set in settings-ui.js is a **client-side merge policy**, not a wire filter. A display key seeds from the server only when localStorage has no value for it, which is what prevents one device overwriting another; `showPlanUsageLimits` is additionally `delete`d from the incoming payload outright. Separately, `SettingsUpdateSchema` is `.strict()` and simply **does not declare** `skin`, `showFileViewerButton`, `showCronButton`, `webglRendererEnabled`, `localEchoEnabled`, `cjkInputEnabled`, or `extendedKeyboardBar`, so sending one of those is a validation error. The rest (`showResponseViewer`, `showPlanUsageLimits`, `language`, and most `show*` keys) ARE in the schema and do persist server-side; they are per-device by client policy only. ⚠️ Adding a new per-device setting means deciding **both** questions: membership in `displayKeys`, and presence in the schema.
 
+**App Settings modal** (`#appSettingsModal`): a left rail that is a **table of contents over ONE scrolling document**, not a tab switcher. Every section stays mounted (`.set-section`, ids `settings-terminal|appearance|layout|models|clis|notifications|voice|shortcuts|system`), the rail follows the scroll, and `switchSettingsTab(id)` keeps its historical name but SCROLLS instead of hiding. Phones swap the rail for the sticky `#appSettingsJump` pill (compact layout at ≤860px in mobile.css). ⚠️ **The load/save contract is `getElementById` by id**: `openAppSettings()`/`saveAppSettings()` read every control by a fixed id, so moving a control between sections is free but renaming or dropping one silently stops it loading or saving. `test/app-settings-structure.test.ts` is the static guard. ⚠️ Model cards (`#appSettingsModelCards`) and the effort segment are **views over hidden `<select>`s** that remain the source of truth; the cards hold the BASE model and the "1M context window" switch composes `base + [1m]` back into `claudeModel`, which is what retires the old "takes precedence over the toggle below" trap. ⚠️ `.modal-tabs`/`.modal-tab-btn`/`.modal-tab-content` are still used by `#sessionOptionsModal` and `#createCaseModal`; the settings rail uses its own `set-*` classes and must not restyle them. ⚠️ `admin-ui.js` injects the multi-user Users entry into `.set-rail-items` + `.set-doc`, so those hooks must survive any restructure.
+
 **Header button visibility**: most header controls are opt-in and hidden by a marker class (`btn-multimonitor--hidden`, `btn-response-viewer-header--hidden`, `btn-file-viewer--hidden`, `btn-cron--hidden`) that `applyHeaderVisibilitySettings()` (settings-ui.js) toggles after settings load; the multi-monitor button is instead stripped at render by `renderIndexHtml`. ⚠️ Hiding must go through the marker class: the base rules are `display:inline-flex !important`, so an inline style cannot override them. Current desktop default is WS/CPU/MEM + File Viewer + gear, with the token chip and lifecycle-log button OFF. ⚠️ New header controls must not leak onto phones; `test/mobile-header-buttons-policy.test.ts` is the static guard. → [architecture-invariants#header-button-visibility-multi-monitor-response-viewer-file-viewer-cron](docs/architecture-invariants.md#header-button-visibility-multi-monitor-response-viewer-file-viewer-cron)
 
 **Gesture control** (camera hand-tracking overlay, opt-in, default OFF): `CODEMAN_GESTURE=1` makes the feature *available*; `gestureControlEnabled` turns it on. The bundle is injected by `renderIndexHtml` only when enabled, which is why that method is `async` and reads settings with `readSettings(true)` (a fresh read: a post-save reload lands inside the 2s cache TTL and would otherwise render the pre-toggle state). **Source lives in `packages/gesture-control/`; edit there, run `npm run build:gesture`, and commit the regenerated bundle** because dev serves the committed bundle with no runtime bundler. The MediaPipe wasm + model are fetched separately and gitignored. ⚠️ Keep `MP_VERSION` in `fetch-gesture-assets.mjs` in sync with `@mediapipe/tasks-vision`. → [architecture-invariants#gesture-control-the-source-package](docs/architecture-invariants.md#gesture-control-the-source-package)

+**Shell keyboard accessory bar + one-shot Ctrl** (issue #262, `keyboard-accessory.js`): a **shell**-mode session automatically swaps the mobile accessory bar for terminal controls (Ctrl, Esc, Tab, four arrows, paste, dismiss); every other mode keeps the agent bar. `setMode()` now records the user's `extendedKeyboardBar` preference as the **base** layout and `refreshForActiveSession()` (called from `selectSession`) resolves base-vs-shell, so a settings save during a shell session cannot yank the bar away and switching back restores the user's choice. ⚠️ **Ctrl is a ONE-SHOT modifier applied in `terminal.onData`, not in a keydown handler**: a virtual keyboard emits no usable key events, so the character only exists as onData text. The hook sits AFTER `shouldSuppressTerminalQueryResponse` (xterm answers DA/CPR through onData too, and one of those would silently spend the modifier) and BEFORE every send path, so the control byte follows the normal control-char route. ⚠️ **Not every onData chunk is a keystroke**, and the query filter is not enough on its own: xterm ALSO emits mouse and focus reports on its own initiative, so the hook skips them via `isTerminalFocusOrMouseReport()` (they still reach the PTY, they just don't count as the next key). The mouse half is live — a shell session keeps the NARROW strip, so mouse DECSETs reach the browser and one tap while vim/htop runs spent the armed modifier silently (measured). The focus half is defense in depth: `FOCUS_ESCAPE_FILTER` in `session.ts` strips `\x1b[?1004h` from every PTY read, so `sendFocusMode` never turns on today; if it ever did, the bar's own post-key refocus would emit `\x1b[I` and eat the modifier before the user typed. ⚠️ It must disarm on ALL of: use, second tap, any other accessory key, session switch, keyboard dismissal, and a layout swap; a modifier left armed turns the next innocent keystroke into a control byte. ⚠️ **onData is not the only input path** — with `cjkInputEnabled` on, the CJK textarea owns the keyboard (onData returns early for everything it swallows, and the focus router sends `terminal.focus()` there, which is where the bar refocuses after every key), so `_handleCjkInput()` applies the modifier too. It is that module's single choke point to the PTY, so one call covers typed characters, IME flushes, Enter, backspace and arrows. Without it an armed modifier could neither fire NOR be spent, and survived to a later keystroke. Mapping is `ctrlByteFor()` (`code & 0x1f` over @A-Z[\]^_ and a-z, plus Ctrl+Space=NUL / Ctrl+?=DEL); characters with no control equivalent pass through unchanged, like a hardware keyboard. ⚠️ The armed style is `.accessory-btn.accessory-btn-ctrl.armed` (0,3,0) in BOTH stylesheets, and it cannot outrank mobile.css's light-skin repaint at **(0,3,1)** (`:is()` inherits its most specific argument, and that list holds `.btn-toolbar.btn-shell`) — so that rule excludes the state by hand as `.accessory-btn:not(.armed)`. Without the exclusion the armed button renders identically to a resting one on all four light skins, which is worse than no armed style at all.
+
 **Phone toolbar: Enter replaces Shell** (post-1.8.0): inside `@media (max-width: 430px)` `btn-shell` is `display:none` and `btn-enter` takes its slot (`order: 4`); starting a shell moved into the Run dropdown (`Terminal / Shell` → `setRunMode('shell')` → `run()` → `runShell()`, button label "Run SH"). `runMode` is `z.string().max(20)` server-side, so new modes need no schema change. Desktop and tablet keep the green Run Shell button unchanged.
 
 ⚠️ **`sendEnterKey()` MUST go through `terminal._core.coreService.triggerDataEvent('\r', true)`** — not `sendInput()`, and never a raw POST to `/api/sessions/:id/input`. `localEchoEnabled` defaults to `MobileDetection.isTouchDevice()`, so on every phone the characters you type are buffered in the `LocalEchoOverlay` and have **never reached the PTY**; the `onData` Enter branch in terminal-ui.js is what flushes `pendingText` first and only then sends `\r` (after an 80ms delay so text lands first). Sending a bare `\r` submits an empty line and strands the typed text on screen, so the button looks dead. Replaying the keypress reuses the overlay flush, the flushed-offset cleanup and the ordering instead of reimplementing them. `KeyboardAccessory.sendKey()` is for escape sequences (arrows/Esc) and is the WRONG template to copy for input.

Pure core `searchSources()` in `search-service.ts` (substring-matches with hard per-type caps — no regex, so no ReDoS; no filesystem reads, so no traversal); `harvestSources()` in `search-routes.ts` gathers the in-memory sources. `SearchQuerySchema` bounds `q` (1–200), allowlists `types` (`session,event,file`), clamps `limit` (1–60).

Past sessions now come from `src/web/session-history-index.ts`: a capped (`HISTORY_INDEX_MAX_ITEMS` 400) snapshot of the unified list, read synchronously by `harvestSources()`. ⚠️ It is filled OUTSIDE the request path, which is what preserves the no-fs property above: `/api/sessions/unified` publishes it as a side effect (free, it just merged that list, and the home screen fetches it whenever it opens, which is the same screen the search box lives on), and `ensureHistorySessionIndexFresh()`, **fire-and-forget, single-flight, TTL-guarded (60s)**, kicks a rebuild when a search finds it stale. A cold process therefore answers its first search without history and its second with it; never `await` the refresher from a handler. ⚠️ The snapshot is stored **UNSCOPED** with a per-row `owner` (`undefined` = host-wide transcript history), and `harvestSources()` re-applies `canAccessOwned()` per row, the same rule `/api/sessions/unified` applies when it drops history for non-admins. A scoped (non-admin) unified request therefore re-merges unscoped before publishing, rather than writing its own subset into the shared snapshot. ⚠️ Live rows are harvested FIRST and win the dedupe, so a session that is both live and in the snapshot keeps `jumpTo.kind:'session'`; history rows get `'resume-session'` (with `claudeSessionId`/`workingDir`), because selecting a tab that no longer exists is a silent no-op the user reads as a broken result.

+ * @fileoverview Bounded in-memory index of PAST sessions, harvested by `GET /api/search`.
+ *
+ * `GET /api/search` used to build its session corpus from the live in-memory
+ * session map alone, so a folder sitting in the home screen's "Resume
+ * Conversation" list matched nothing (issue #261). The corpus that list renders
+ * comes from `GET /api/sessions/unified`, which reads the lifecycle log and every
+ * Claude transcript file: disk I/O the search path deliberately does not do (its
+ * no-fs property is what keeps a per-keystroke query cheap and traversal-free).
+ *
+ * This module is the seam between the two: a capped snapshot of the unified list
+ * that the search route reads synchronously, refreshed OUT of the request path.
+ * Two things fill it:
+ *   1. `/api/sessions/unified` writes it as a side effect (free, it just merged
+ *      that list). The home screen calls that endpoint whenever it opens, which
+ *      is the same screen the search box lives on, so it is warm in practice.
+ *   2. `ensureHistorySessionIndexFresh()`, fire-and-forget, single-flight,
+ *      TTL-guarded, kicks the registered refresher when a search finds the
+ *      snapshot stale. The caller never awaits it: the current query answers from
+ *      the existing snapshot and the next one sees fresh data.
+ *
+ * OWNERSHIP: each item carries the `owner` of the session it came from, and rows
+ * not tied to any live/persisted session (host-wide transcript history) carry
+ * `owner: undefined`. `canAccessOwned()` then reproduces the unified route's rule
+ * exactly, in multi-user mode a non-admin sees neither other users' sessions nor
+ * unowned host-wide history, and in single-user mode every check short-circuits
+ * true. The snapshot is written UNSCOPED, so it must never be returned unfiltered.
+ *
+ * Key exports:
+ * - setHistorySessionIndex / getHistorySessionIndex: the snapshot accessors.

+ *
+ * With ~35 past sessions the list showed 4 rows, then a button that dumped every
+ * remaining row into a fixed 240px box, with no way to sort or filter. The fix
+ * moved rendering into `_renderHistoryList()` over a cached corpus, so what is
+ * worth pinning is the model, not the pixels:
+ *   1. the collapsed page is _HISTORY_INITIAL_COUNT rows, not 4,
+ *   2. "Show more" expands the LIST and marks the box expanded (the CSS cap is
+ *      class-driven, without the class, expanding just deepens a scroll well),
+ *   3. filtering matches name / folder / case label / prompt, and implies
+ *      expansion (hiding matches behind "Show more" defeats typing a filter),
+ *   4. sorting is alphabetical by name or folder, with pinned rows still on top.
+ *
+ * Loaded via `vm` against a stub CodemanApp with a fake DOM, same harness as
