# Frontend Navigation Audit — the "opaque click" anti-pattern

> **Status, 2026-07-31.** H1 (jobs), H2 (dashboards) and H4's groundwork are **done** — rows are real
> `<Link>`s and selection lives in `?selected=` / `useParams`. **H3 is void: the Projects feature was
> deleted**, so every reference to `Projects/`, `SELECTED_PROJECT` and `/projects/:id` below is historical
> and should be read as an example of the pattern, not as work to do. **H4 (chat detail reading
> `sessionId` from `useParams` rather than the `chat:selected-session` channel) is the one item still
> open.** The rules in this file are current and authoritative; the findings table is a snapshot.


**Date:** 2026-07-30 · **Origin:** written as exploration before any of the routing work was done.

Prep work for the upcoming **full navigation refactor**. This catalogues every place the frontend
navigates to / selects an **addressable entity** using a `<button onClick>` / `<div onClick>` /
imperative `navigate()` / global-channel setter **instead of a real `<Link to>` / `<a href>`**.

> Line numbers were captured on `sidecars-claude` at audit time and may drift as other work lands —
> treat them as anchors, re-grep the symbol if a line looks off.

## The anti-pattern (definition)

A clickable element selects/opens something that has (or should have) a URL, but:
- **(a)** the entity id/slug is **not in the DOM** (no `href`, no `data-*`) — it lives only in an onClick closure;
- **(b)** clicking **doesn't change the URL** (or does so only via an indirect state→URL effect);
- **(c)** selection is held in **JS state / a global channel** (`usePanelChannel`, `useGlobal`), not the URL;
- **(d)** **no anchor semantics** — can't cmd/ctrl-click to a new tab, no middle-click, not link-focusable.

**Exemplar (already fixed):** the `/chat` session list. Rows were `<button onClick={() => selectById(id)}>`
(id only in the closure) → converted to `<Link to={`/chat/${session.id}`}>` (committed to master `f35c145`).
That fix is the template for the HIGH items below. **Caveat:** the fix only did the *rows* — the chat
**detail panel** still selects via channel, not the URL (finding **C1**), so `/chat` is the model for both
"done right" (rows) and "still to do" (detail).

## Route map (from `App.tsx`)

**Existing entity routes:** `/chat/:sessionId`, `/jobs/:id`, `/dashboards/:id`, `/email/:emailId`,
`/browser/:tabId`, `/tasks/:dirName`, `/skills/:dirName`, `/processes/:dirName`, `/task-logs/:id`,
`/activity/:id`. (`/projects/:id`
was in this list; the Projects feature was removed end to end on 2026-07-30, so the route is gone with it. H3
and navigate-site 22 below still name it — they are the record of work that happened, not of code that exists.)
**Section routes** (a param that names a view rather than an entity): `/settings/:page/:section`,
`/soulseek/:section`, `/headscale/:section`, `/wallet/:section`, `/system-monitor/:scope`.
**Query-param screens:** `/music?path=`, `/files?path=`, `/code-editor?file=`.
**Genuinely flat, still:** `/` `/plans` `/terminal` `/desktop` `/qr-transfer`. Of these only `/plans` selects
something (M9); the other four have nothing addressable to put in an address.
The five settings pages are route **pairs** now, not flat screens — `/settings/{profile,ai,system,integrations,user-management}`
plus a `:section` each (M6). There has never been a `/settings/apps`; that entry was wrong when this list
was written.

**What's already correct** (lean on these in the refactor): the **Dock**, **Header** (logo + mobile sheet),
**UserMenu**, **JobsIndicator** are all real `<Link>`s. Shared `NavLink.tsx` (query-string-appending `<Link>`
wrapper — note: *not* react-router's NavLink, gives no active state) and `BackButton.tsx` (`<Link>` back arrow)
are good building blocks. The **Workspace/Panel framework** contains **zero** route navigation — it's orthogonal.

## Consolidated findings — severity ranked

### 🔴 HIGH — addressable route already exists; just needs a `<Link>` / URL-as-source-of-truth

| ID | file:line | Entity | Current impl | Fix |
|----|-----------|--------|--------------|-----|
| H1 | `Screens/Dashboard/Jobs/JobsPage.tsx:108` | a job | `<button onClick={() => navigate(`/jobs/${job.id}`)}>` — id in closure | → `<Link to={`/jobs/${job.id}`}>`. Active-row already keys off `useParams().id`; keep the stop/delete button. **The exact twin of the /chat fix.** |
| H2 | `workspaces/…/apps/Dashboards/DashboardListApp.tsx:133` | a dashboard | `<div onClick={handleClick}>` → `useGlobal(SELECTED_DASHBOARD_KEY)` on-page (**no URL change**), `navigate()` off-page | rows → `<Link to={`/dashboards/${ws.id}`}>`; drop the global as selection source (derive from `useParams`). Header is already a `<Link>` — app is internally inconsistent. |
| H3 | `workspaces/…/apps/Projects/ProjectListApp.tsx:161` | a project | `<div onClick={handleClick}>` → `useGlobal(SELECTED_PROJECT)` on-page (**no URL change**), `navigate()` off-page | identical to H2 → `<Link to={`/projects/${p.id}`}>`; retire `SELECTED_PROJECT` as source of truth. |
| H4 | `workspaces/…/apps/ChatHistory/ChatDetailPanel.tsx:136` | which chat to render | reads `usePanelChannel('chat:selected-session')`, **not** `useParams` | make the route the source of truth: read `sessionId` from `useParams`, fetch by id, retire `chat:selected-session` (or make it a derived cache). **Finishes the /chat fix.** |
| ~~H5~~ | ~~`Screens/Dashboard/Email/EmailList.tsx:336`~~ | ~~an email~~ | ~~`<button data-email-id onClick={setSelectedId}>` + `EMAIL_SELECTED` channel + a state↔URL sync effect (`EmailScreen.tsx:27-33`)~~ | **Done.** Rows are `<Link to={emailPath(msg.id)}>`, list + reader + mobile-panel all read `useSelectedEmailId()` (`Email/shared.ts`), and `EMAIL_SELECTED` plus both sync effects are deleted. Arrow-key browsing navigates with `replace` so a sweep doesn't stack history. |

> **Verify:** `Dashboards/DashboardPreview.tsx:355,377` and `Projects/ProjectPreview.tsx:430,457` also
> `navigate('/…/:id')`. The nav auditor read these as HIGH "open entity"; the apps auditor read the Project
> ones as *correct* post-create/edit flows. Eyeball them during H2/H3 — convert the ones that are "open an
> existing entity from a preview", leave genuine post-mutation redirects.

### 🟠 MEDIUM — navigable entity with **no route yet** (add a route, then link)

| ID | file:line | Entity | Proposed route | Note |
|----|-----------|--------|----------------|------|
| ~~M1~~ | ~~`Screens/Dashboard/CapabilityPage.tsx:431`~~ | task / skill / process | `/tasks/:dirName`, `/skills/:dirName`, `/processes/:dirName` | **Done.** One component backed three screens, so one change covered all of them. The auto-select-`items[0]` effect is gone — the bare route is now the list with an empty detail pane. `editing`/`isNew` moved to `?edit=1` / `?new=1` because a `<Link>` row cannot imperatively reset them. |
| ~~M2~~ | ~~`Screens/Dashboard/TaskLogs/index.tsx:104`~~ | a task-log run | `/task-logs/:id` | **Done.** As predicted — the detail fetch already keyed off the id, so only its source changed. `showDetail` is gone; the mobile swap and both back arrows derive from the param. |
| ~~M3~~ | ~~`Screens/Dashboard/Activity/ActivityScreen.tsx:63,73`~~ | background task / detached job | `/activity/:id` | **Done.** One param for both row kinds; the screen looks the id up in the polled registry and derives `task=`/`path=` from the row. The SSE effect now depends on that derived *string*, so the 3s poll no longer risks re-opening the stream. An id that has left the registry says so instead of hanging on "waiting for output". |
| ~~M4~~ | ~~`FileBrowser/.../useFileBrowserApp.ts:269`~~, `FileItem.tsx:516`, ~~`Breadcrumb.tsx:16`~~ | a folder | `/files?path=<dir>` | **Partly done — the rest is an owner decision, not a defect.** `currentPath` is `?path=` on `/files`, so back/forward and linking a folder work, and the crumbs are `<Link>`s. Two things the audit line did not know: `?view=` is *ephemeral* (wiped on mount by `useFileViewerPanels`), so `path` is the screen's first durable param, and four `setSearchParams({…})` calls replaced the whole query string — opening any file would have silently reset the folder. They go through a `setViewerParams` helper now that keeps `path`. Opt-in via the parsed `WorkspaceIdentity` (`screens/files`), because a dashboard can hold two browsers and one shared param would move both. **Folder *items* stay buttons:** ⌘/Ctrl/Shift-click is already bound to multi-select in `FileItem.tsx` and open is double-click, so anchor semantics collide with an existing gesture. |
| ~~M5~~ | ~~`CodeEditor/FileTree.tsx:59`, `EditorTabs.tsx:33`~~ | open source file / active tab | `/code-editor?file=<path>` | **Done, minus `open=`.** The active file is `?file=`; tree *file* rows and tabs are `<Link>`s. **The tab set stays local** — it is a working session, not an address: it grows without bound, each entry costs a read on load, and nobody links someone else to a tab bar. A `?file=` naming a file that is not open now *opens* it, which is what makes a pasted link work; a path that fails to read is remembered so a bad link errors once instead of once per render, and the address is left alone rather than rewritten. **Tree folder rows stay buttons** — unlike the M4 case this needs no owner call, because expanding a directory is disclosure, not navigation. Two things fixed in passing: the tab close control was a `role="button"` span *nested inside* the tab (invalid then, a nested interactive inside an anchor now) and is a sibling `<button>` with an `aria-label`; and `closeFile` computed the next-active file *inside* a `setFiles` updater, which is exactly the impurity React double-invokes to catch. |
| ~~M6~~ | `Settings/SettingsPanel.tsx` | a settings sub-section | `/settings/:page/:section` | **Done.** `<NavLink>` + `useParams`, five `*_SELECTED` globals gone, one `SettingsRoute` guard per page. The "one change covers all settings pages" claim was *almost* right: Integrations builds its own sidebar and did not go through `createSettingsPanelComponents`, and it also held the Enterprise/Personal tab in a second global — derived from the section key now, which is what fixes deep-linking a Personal section. |
| ~~M7~~ | ~~`workspaces/components/Combobox.tsx:53`~~ | caller-supplied route | — | **Deleted, not fixed.** "Every caller inherits the opaque click" was the reason this ranked MEDIUM, and it is wrong: `Combobox` has **no callers**. Nothing has imported it since the initial commit, there is no barrel export, and nothing anywhere sets `href` on a `SelectOption` — so the navigate, the separator that only showed for `href` options, and the `href` field on both declarations of the type were all unreachable. Writing anchor semantics into a component that is never rendered is building, not fixing. Its `Command` primitives stay; `AIHarnessesSection` uses them. |
| ~~M8~~ | `Layout/Header/UserMenu.tsx` | — | — | **Done.** Removed rather than routed: nothing had ever been built behind `/settings/resources`, so the item was a bounce to `/` dressed as navigation. Its `header.userMenu.resources` locale keys went with it. |
| M9 | `Screens/Dashboard/Plans/index.tsx:36` | a plan document | `/plans/:name` | native `<select>` → local state; a plan is a real addressable doc. Have the select `navigate()` or use a link list. |
| ~~M10~~ | `SystemMonitor/ScopeList.tsx` | monitor scope (btop/pm2/docker) | `/system-monitor/:scope` | **Done.** Route pair + `Navigate` guard; the scope buttons are `NavLink`s and `useMonitorScope` reads `useParams` instead of the channel. The Dock's hand-rolled `isActive` is a `startsWith`, so its highlight survives the redirect. |

**Music** (M-music) and **Soulseek** (M-slsk) are whole-workspace channel apps — pulled out below because each
is **one design decision** that cascades across many files:

- ~~**Music**~~ — **done.** The library location is `/music?path=<rel>` (`rel` relative to the `Music` root);
  `music:cwd` is deleted. Each panel calls `useMusicCwd()` and reads the param itself, so `MusicBrowser`,
  `MusicDetail` and `FavoritesView` no longer tell each other anything. Every drill-in is a `<Link>` — library
  rows, folder rows, album/artist cards, both "up" affordances, the favorites rows, and the dock's now-playing
  tile. Track rows stay `<button>`s: they play, which is a mutation. Two things that were channel-shaped and
  stayed channels: `music:favorites` (a view toggle over this one panel) and `music:resync` (a refresh signal).
  A query param rather than `/music/*` because the location is only one of the things this screen holds — the
  lyrics split and the favorites view are the others — and because a splat has to be a route's last segment.
  **Needs runtime test.**
- ~~**Soulseek**~~ — **mostly done.** The section is `/soulseek/:section` (nav entries are `NavLink`s, the
  view panel reads the same URL), the peer is `?user=<name>`, and the past-search was already `?search=<id>`.
  The `soulseek:section` and `soulseek:user` channels are deleted; `soulseek:refresh` stays, which is a
  signal and not selection. The peer went in the query string rather than `/soulseek/users/:name` as
  sketched here, because the section nav has to stay a one-segment `NavLink` — a second path segment would
  need a nested route just to keep the highlight, and the query string is what `?search=` already uses.
  Still on `useState`: rooms (`SoulseekRooms`) and conversations (`SoulseekChat`).

### 🟡 LOW / borderline

- **Dock / Header active styling** (`Dock.tsx:43,78` · `Header.tsx:53,112`) — destinations are already real
  `<Link>`s; only the *active* class is JS-derived from `useLocation`. Switch to react-router `<NavLink>` and drop the hand-rolled `isActive`.
- ~~**Browser tabs**~~ (`Browser/TabList.tsx:93`) — **done, against this file's own advice.** The objection
  was that a CDP target id is ephemeral, so a durable `/browser/:tabId` is dubious. True of *bookmarking*,
  and irrelevant to everything else the URL buys: the id was in an onClick closure, three components read a
  `BROWSER_SELECTED_TAB` global, and the row could not be cmd-clicked. Staleness is handled where it
  actually shows up — the preview now distinguishes "no tab open" from "that tab is no longer attached"
  by checking the polled target list, which it gets from the same React Query key the list uses, so it
  costs no extra request. En route: the row's Focus and Close buttons were nested *inside* the row
  `<button>`, which is invalid HTML and only worked because of two `stopPropagation` calls; they are
  siblings of the anchor now. And its "Set up in Integrations" was a raw `<a href>` that reloaded the SPA.
- **Jobs step/iteration** (`Jobs/JobDetail.tsx:234,255`) — intra-detail sub-selection; only if we want `/jobs/:id/:stepKey` deep links.
- **Preview slug** (`Preview/PreviewApp.tsx:23`) — Preview usually derives its target from the surrounding dashboard/project `cwd`; the manual picker is a fallback. Probably leave URL-less.
- **FileBrowser widget** (`FileBrowserWidget/.../BrowseTab.tsx:36`) — compact sidebar widget; keeping its browse cursor local is defensible.
- **Music favorites view** — the channel is `music:favorites`, not `music:fav`. **Decided: it stays a channel.**
  It is a view of the detail panel rather than a location, it survives no reload worth surviving, and the one
  case where its being off-URL shows is handled explicitly: going Home or opening a favorite closes it by hand,
  because navigating to where you already are fires no route change. (**SystemMonitor scope** was listed here
  as the same kind of thing and was not — it is M10, and it is in the URL.)
- **"New Chat" button** (`ChatHistory/SessionList.tsx:68`) — a create-action that also `navigate('/chat/new')`; could be `<Link to="/chat/new">` if the state-set moves into the route. Its `chat:selected-session` write is part of the H4 cleanup.

## Channel-based selection map (the core of the refactor)

Every place an **addressable entity** is selected through a global channel / global state instead of the URL.
This is the primary surface to convert to URL-driven selection.

| Channel / global key | Entity held | Should map to | Files |
|----------------------|-------------|---------------|-------|
| `chat:selected-session` | open chat session | `/chat/:sessionId` | `ChatDetailPanel.tsx:136`, `SessionList.tsx:16` (H4) |
| `chat:active-cwd` | chat working dir | query param on `/chat` | `ChatDetailPanel.tsx:102`, `SessionList.tsx:14` |
| `SELECTED_DASHBOARD_KEY` (`useGlobal`) | selected dashboard | `/dashboards/:id` | `DashboardListApp.tsx:36`, `DashboardPreview.tsx:287` (H2) |
| `SELECTED_PROJECT` (`useGlobal`) | selected project | `/projects/:id` | `ProjectListApp.tsx:45`, `ProjectPreview.tsx:386` (H3) |
| local `useState` selections | search / room / conversation / peer / open file / preview slug | respective nested routes | `SearchView`, `SoulseekRooms`, `SoulseekChat`, `SoulseekUsers`, `CodeEditor/useEditorState`, `PreviewProvider` |

**Excluded — event-bus / refresh signals, NOT selection:** `files:refresh-signal`,
`SLSKD_REFRESH_CHANNEL`, `MUSIC_RESYNC_CHANNEL`.
(`FILE_VIEWER_CHANNEL` was listed here too; it had no publisher and has been deleted — the file viewer
reads `?view=` from the URL. `preview:refresh` and `chat:active-session` were also listed, and
`preview:refresh` was cited above as the exemplar of a *legitimate* channel — but both have a publisher
in `ChatPanelWrapper` and **no subscriber at all**, and `preview:refresh`'s reader, `PreviewProvider`, is
no longer in the repo. They are declared in `officerdev/src/channels.ts` with that stated; deleting the
publishers means changing the chat panel, which is another agent's, so it is written up in
`COMMS/chat-agent-handoff-2026-08-07.md` instead. Use `files:refresh-signal` as the exemplar.)

## Appendix A — all `navigate()` call sites (whole frontend, 25)

"Link?" = a `<Link>`/`<NavLink>` is the right refactor.

| # | file:line | what | target | Link? | note |
|---|-----------|------|--------|-------|------|
| 1 | `Jobs/JobsPage.tsx:109` | job list row | `/jobs/:id` | **YES** | H1 |
| 2 | `Dashboards/DashboardListApp.tsx:90` | dashboard row (off-page) | `/dashboards/:id` | YES | H2 |
| 3 | `Dashboards/DashboardListApp.tsx:114` | inside "New Dashboard" | `/dashboards` | ~ | create action |
| 4 | `Dashboards/DashboardPreview.tsx:355` | open dashboard | `/dashboards/:id` | YES | verify vs H2 |
| 5 | `Dashboards/DashboardPreview.tsx:377` | open dashboard | `/dashboards/:id` | YES | verify vs H2 |
| 6 | `Projects/ProjectListApp.tsx:116` | project row (off-page) | `/projects/:id` | YES | H3 |
| 7 | `Projects/ProjectListApp.tsx:142` | inside "New Project" | `/projects` | ~ | create action |
| 8 | `Projects/ProjectPreview.tsx:430` | open project | `/projects/:id` | YES | verify vs H3 |
| 9 | `Projects/ProjectPreview.tsx:457` | open project | `/projects/:id` | YES | verify vs H3 |
| 10 | `Jobs/JobDetail.tsx:709` | back button | `/jobs` | YES | use `BackButton`/`<Link>` |
| 11 | `ChatHistory/SessionList.tsx:70` | "New Chat" | `/chat/new` | ~ | borderline (LOW) |
| ~~12~~ | ~~`components/Combobox.tsx:54`~~ | nav combobox option | `option.href` | — | M7 — file deleted, it had no callers |
| ~~13~~ | `MusicPlayer/MusicPlayerHost.tsx:251` | open current album (setCwd+nav) | `/music` | ~ | **Done** — the side-effect was the `setCwd`; with the location in the URL the tile is a plain `<Link>` to `musicPath(albumRel)`. |
| 14 | `FileBrowserWidget/useFileBrowserWidget.ts:53` | open folder in Files | `/files?view=…` | ~ | query nav |
| 15 | `FileBrowserApp/useFileBrowserApp.ts:401` | create dashboard from folder | `/dashboards/new?…` | ~ | action-nav |
| 16 | `FileBrowserApp/useFileBrowserApp.ts:427` | create dashboard from files | `/dashboards/new?…` | ~ | action-nav |
| 17 | `FileBrowserApp/.../TaskRunnerModal.tsx:1168` | after starting job | `/jobs` `/jobs/:id` | NO | post-submit |
| 18 | `FileBrowserApp/.../TaskRunnerModal.tsx:1649` | after starting pipeline | `/jobs/:id` | NO | post-submit |
| ~~19~~ | ~~`Email/EmailScreen.tsx:29`~~ | ~~sync selection → URL (effect)~~ | — | — | deleted (H5) |
| ~~20~~ | ~~`Email/EmailScreen.tsx:31`~~ | ~~clear selection → URL (effect)~~ | — | — | deleted (H5); the mobile Back button navigates to `/email` instead |
| 21 | `ChatHistory/index.tsx:107` | redirect when no id | `/chat` | NO | guard |
| 22 | `Projects/ProjectListScreen.tsx:66` | clear/redirect | `/projects` | NO | guard |
| 23 | `Authentication/ForgotPassword/useResetPassword.ts:48` | post-reset redirect | `/` | NO | action result |
| 24 | `Authentication/LandingPage/Bootstrap.tsx:34` | post-bootstrap redirect | `/` | NO | action result |
| 25 | `hooks/useQueryState/useQueryState.ts:39` | generic query-state writer | dynamic | NO | infra hook |

## ✅ TO-DO — ordered for tomorrow

> **Progress — 2026-07-30, branch `navigation-refactor` (off master; NOT yet runtime-tested):**
> H1, H2, H3 implemented and tsgo-clean. **Design correction for H2/H3:** the naive "row → `<Link to="/dashboards/:id">`"
> would destroy the *preview-on-list* feature (that route is the full page). The faithful fix — which is what
> was implemented — moves selection out of the `SELECTED_*` global into a **`?selected=<id>` URL param** read by
> the list, the screen (mobile panel), and the preview; rows are real `<Link>`s (`/…?selected=id` on-page,
> `/…/:id` off-page) with the action buttons kept as **siblings** of the anchor, not nested inside it. Same
> approach will suit any future "master list + live preview" screen. **Must verify on next restart:** preview,
> create/edit/delete(/publish), and mobile-panel flows on `/dashboards` and `/projects`.

### Phase 1 — Quick wins (routes already exist; mechanical, high value)
- [x] **H1** Jobs rows → `<Link to={`/jobs/${job.id}`}>` (`JobsPage.tsx`). Done — `46482f3`. (active-row highlight already keyed off `useParams().id`.)
- [x] **H2** Dashboards rows → `<Link>`; `SELECTED_DASHBOARD_KEY` global replaced by `?selected=` URL param across `DashboardListApp`/`DashboardsScreen`/`DashboardPreview`. Done — `01365cb`. **Needs runtime test.** (The constant itself outlived its last reader by four months and has now been deleted; its siblings in `Dashboards/constants.ts` are dialog form state, not selection, and stay.)
- [x] **H3** Projects rows → `<Link>`; `SELECTED_PROJECT` global replaced by `?selected=` URL param across `ProjectListApp`/`ProjectListScreen`/`ProjectPreview`. Done — `2aaacc8`. **Needs runtime test.**
- [ ] **H4** Chat detail: read `sessionId` from `useParams`, retire `chat:selected-session` as source of truth (`ChatDetailPanel.tsx:136`) — **finishes the /chat fix**. *Deferred: overlaps the in-flight `sidecars-*` chat-comms work; do after that lands.*
- [x] **H5** Email rows → `<Link>` driven by `useParams().emailId`; the `EMAIL_SELECTED` global and both state↔URL sync effects are gone. **Needs runtime test.** (`EMAIL_FOLDER` stays a `useGlobal` for now — it is read in one component and is view state, not selection; putting the folder in `?folder=` is a separate, smaller item.)
- [x] **M8** Dead `/settings/resources` menu item removed from `UserMenu.tsx`, along with its now-orphaned `en`/`pt` locale keys. **Needs runtime test.**
- [ ] Verify + convert the 4 preview "open" navigates (`DashboardPreview:355,377`, `ProjectPreview:430,457`); leave genuine post-mutation redirects.

### Phase 2 — Add a route, then link (per-entity, medium effort)
- [x] **M6** Settings sub-sections → `/settings/:page/:section`; `SectionButton` is now a `SectionLink` (`<NavLink>`), the five `*_SELECTED` globals and `INTEGRATIONS_SETTINGS_TAB` are gone, and each page renders one `SettingsRoute` guard that canonicalises the bare route and a bogus section. **Needs runtime test.**
- [x] **M1** Capabilities → `/tasks|skills|processes/:dirName`, rows → `<Link>`; `CapabilityPage` takes an explicit `basePath` (not reused from `endpoint`, which only happens to match). Selection is `useParams`, the mobile pane swap and back arrow are derived from it, delete navigates to the bare route, and the two per-item modes are `?edit=1` / `?new=1`. No `<Navigate>` guard: an unknown `dirName` gets the empty detail pane. **Needs runtime test.**
- [x] **M2** TaskLogs → `/task-logs/:id`; rows are `<Link>`s, `showDetail` deleted. **Needs runtime test.**
- [x] **M3** Activity → `/activity/:id`; the `{label, query}` selection object is gone — the id is the URL and the stream query is derived from the registry row. `/activity` also had no `usePageTitle` rule (it read "Officer"); added. **Needs runtime test.**
- [x] **M4** FileBrowser folders → `/files?path=`; breadcrumbs are `<Link>`s. Folder *rows* deliberately still buttons — ⌘-click is multi-select, open is double-click; converting them needs an owner call on the gesture.
- [x] **M5** CodeEditor active file → `/code-editor?file=`; tree file rows and tabs are `<Link>`s. The open-tab *set* stays local state, on purpose — see the findings row.
- [x] **M7** Combobox — **deleted instead**. Zero callers since the initial commit; `href` on `SelectOption` was never set by anything, so the whole branch was unreachable.

### Phase 3 — Whole-workspace routing decisions (needs a design call first)
- [x] **Music** — `/music?path=<rel>`; `music:cwd` deleted; every drill-in (including the dock's now-playing tile, navigate-site 13) is a `<Link>`. `music:favorites` and `music:resync` stay — a view toggle and a refresh signal. **Needs runtime test.**
- [x] **Soulseek** — `/soulseek/:section` with the peer in `?user=` and the search already in `?search=`; the two selection channels are deleted. Rooms and conversations are still `useState`. **Needs runtime test.**
- [x] **M10** SystemMonitor scope → `/system-monitor/:scope`; `monitor:scope` channel deleted. **Needs runtime test.**
- [ ] **M9** Plans → `/plans/:name` (`Plans/index.tsx:36`).

### Phase 4 — Polish + borderline decisions
- [ ] Dock + Header + mobile sheet → react-router `<NavLink>` for active state; drop hand-rolled `isActive` (`Dock.tsx`, `Header.tsx`).
- [ ] "New Chat" → `<Link to="/chat/new">` (`SessionList.tsx:68`) once H4's channel cleanup lands.
- [ ] Jobs back button + any `navigate('/jobs')` → shared `BackButton` (`JobDetail.tsx:709`).
- [ ] Decide/skip: Jobs step deep-link, Preview slug, FileBrowser widget. (Browser tabs: **done** — see the LOW section. Monitor scope: **done** as M10, it was not a view toggle. Music favorites: **decided** — stays a channel, reasoning in the LOW section.)

### Cross-cutting for the refactor itself
- [ ] Standardise a URL-as-source-of-truth pattern for panel selection (replace the `usePanelChannel`/`useGlobal`
      selection channels in the map above with `useParams`/`useSearchParams`, keeping channels only for
      genuine signals/refresh buses).
- [ ] Adopt `<NavLink>` (real react-router) for all nav chrome so active state stops being JS-derived.
- [ ] Keep `NavLink.tsx` (query-string wrapper) and `BackButton.tsx` as the standard building blocks.

## Coverage

- **Area 1 — Dashboard screens** (`Screens/Dashboard/**`, excl. Settings/Layout): 9 findings (2 HIGH, 4 MEDIUM, 3 LOW) + spillover to `officerdev` apps.
- **Area 2 — Workspace panel apps** (`workspaces/officerdev/src/apps/**`): 22 findings (4 HIGH, ~15 MEDIUM, 3 LOW); 11 distinct channel-selection sites.
- **Area 3 — Global nav / Layout / Settings / shared components**: 6 findings (0 HIGH — chrome is already links; 3 MEDIUM, 3 LOW) + the 25-site `navigate()` map.

Raw per-area findings (with full impl / id-in-DOM / URL-change / coverage notes) were produced in the
audit run; this document is the consolidated, de-duplicated synthesis. The three HIGH clusters
(Jobs · Dashboards · Projects) plus the two chat halves (rows done, detail = H4) are the direct siblings of
