feat(files): add scoped editor tabs and archive selections - #941
Server Files now opens a file or folder from a namespaced server URL. The local Monaco editor keeps separate drafts for open files and saves edits in order. Failed writes remain available for retry while the dashboard session is open. Closing a tab waits for saving, and deleting a folder waits for writes to its descendants.
Selected files and folders can be downloaded together, archived on the server or deleted. Archives retain relative paths, reject protected entries and existing destinations, and are completed before download headers are sent. Bulk delete reports failed paths individually.
Verified the complete Linux file-agent suite, API gateway, gateway protocol, WebSocket proxy and RBAC package tests, file manager and server-detail component tests, TypeScript and dashboard lint. A Playwright test in Chrome opens an unlisted file through its URL, edits it in Monaco and checks the autosave request and folder navigation.

Walkthrough
The change adds ZIP archive creation and download routes to the agent and API. It updates the web file workspace with deep-linked editor tabs, scoped drafts, folder expansion, and bulk archive and deletion actions.
The agent validates selected paths and creates ZIP archives for download or server-side storage. It rejects selections that violate path, entry, file-type, or size limits. Tests and API documentation cover the routes and responses.
Archive API proxying api/cmd/main.go, api/internal/gatewayprotocol/*, api/internal/ws/dialer.go, api/internal/ws/archive_route_test.go, api/internal/rbac/middleware_test.go, api/docs/openapi.yaml, api/specs.md
The API proxies archive GET and POST requests, recognizes them as long-running transfers, and forces attachment disposition for archive downloads. The proxy checks server UID headers. Tests cover request routing and authorization.
File draft save and removal lifecycle web/src/lib/fileDrafts.ts, web/src/lib/fileDrafts.test.ts
The new draft manager serializes saves, retains drafts and write errors, and waits for pending writes before removing a path and its descendant drafts.
The server detail route accepts a validated file path and selects the Files tab for deep links. The editor loads files by path, maintains multiple draft-backed tabs, and scopes file requests with the expected server UID. Tests cover draft persistence, deep links, and file writes.

The file tree supports folder expansion and multi-path selection. Selected paths can be downloaded as a ZIP, archived on the server, or deleted. The workspace reports partial deletion failures and retains refused selections.
GameplanePanel/Gameplane#862: It changes attachment disposition handling in api/internal/ws/dialer.go and file-type checks in the agent file-access path, which overlap with this change.
Suggested labels: type: feature, area: agent, area: api, area: web
Merge Risk: Moderate · previous review bf550
Narrow-screen users can lose access to an edited file opened through a deep link, and a failed folder deletion can leave edits unsaved until the user edits again. The repository's design-update requirement is also unmet. These should be fixed or explicitly accepted before merging. The API contract issues are small.

Explanation
The title "feat(files): add scoped editor tabs and archive selections" matches the main changes. The PR adds scoped editor tabs (per cluster, namespace, server UID, and path) for the Server Files editor and adds ZIP archive creation and download for multi-path selections, across the agent, API gateway, WebSocket proxy, RBAC, web UI, and docs. The title is concise, uses a conventional commit prefix, and names both primary aspects without file lists or vague terms.
Full details: Linked Issues check
Explanation
Issue #935 is the only active direct link. Its coding requirements are covered by the whole-PR summary (base e3826d8, head bf550b5).
(1) Tree, deep links, tabs: web/src/routes/tabs/FileTreeRows.tsx adds a navigable tree. tree.tsx and ServerDetail.tsx add the file search parameter. Files.test.tsx covers opening a deep-linked file that its parent listing omits. Scope uses cluster, namespace, server UID and path: endpoints.ts sends X-Gameplane-Server-UID, and FileDrafts keys drafts by path.
(2) Autosave and drafts: fileDrafts.ts serializes saves per draft, keeps failed drafts for retry, and retains drafts across tab changes. fileDrafts.test.ts covers retry. remove() waits for pending saves and blocks recreation of deleted descendants. Atomic file creation is not changed in the summary. It is a preserve-only requirement and no change to the create path is listed, so no regression is shown.
(3) Bulk operations: archive_linux.go creates ZIPs with relative paths. It rejects duplicate member names, dotfiles, non-regular files and symlinks. It enforces limits of 256 paths, 10,000 entries and 1 GiB, and returns 413 on limit errors. files.go adds the archive route and a single-archive lock. The API gateway and protocol.go allow only the archive route. ws/archive_route_test.go rejects a changed target UID with 409. middleware_test.go rejects an unrelated user with 403. Files.tsx reports partial bulk-delete failures.
(4) Tests: archive_test.go covers refused selections and no published archive. The RBAC, ws, fileDrafts, Files.test.tsx and fileWorkspace.spec.ts tests cover the listed verification areas.
No concrete unmet coding requirement appears in the evidence. The summary is the only evidence used. I did not run the test suites or read the source directly.
Full details: Out of Scope Changes check
Explanation
Every changed area maps to #935 objectives or their verification:
Agent archive code, handler lock, route timeouts and tests implement bulk ZIP creation and download.
API gateway, protocol allowlist, duration.go, main.go and ws dialer changes implement archive routing, RBAC-bound proxying, the UID target check and attachment headers.
OpenAPI files and specs.md documents describe those same endpoints.
Web changes (endpoints.ts, fileDrafts.ts, router, ServerDetail.tsx, FileTreeRows.tsx, Files.tsx) implement tabs, deep links and draft handling.
i18n strings and the changelog entry describe the new UI.
The e2e spec covers direct file opening and autosave.
No change is shown to be unrelated to the issue. The removed unsaved-change confirmation helper and its test replace the single-selection draft flow. This change follows from the requirement to preserve drafts across tab changes.

- Line 373: Update the shared parameters for the endpoint with the {name} path
template to declare a required path parameter named name with a string schema,
so the path parameter is defined for its operations.
Review comments at @api/internal/ws/dialer.go:
- Line 246: Update the stale-server error branch in the WebSocket dialer to use
httperr.WriteCode with status 409, or an existing registered localized message,
so responses honor application/problem+json negotiation while preserving the
conflict status.
Review comments at @web/src/lib/fileDrafts.ts:
- Around line 122-123: Update the `remove` cleanup so drafts no longer being
deleted resume autosave when they remain dirty: after clearing `deleting`,
schedule a save only if the draft is still the current entry, autosave is
enabled, it has no error, and its text differs from its saved text. Preserve the
existing removal cleanup and change notification.
Review comments at @web/src/routes/tabs/Files.tsx:
- Around line 372-383: Keep the open-file tabs rendered in a pane accessible
after “Back to files” hides <main>, or provide a workspace control to reopen the
selected draft. Update the open-file <nav> and its surrounding responsive layout
so drafts opened through deep links remain reachable even when absent from the
file tree.
- Around line 316-321: The Files screen’s new ZIP and delete controls and tab
navigation lack a corresponding design update. Update the Files screen design to
represent these visual changes and ensure the design exports reflect the updated
screen.

18. **Scout once, brief many:** one scout reads code/docs/failures and writes a factual brief (exact `file:line`, before/after code, justification). Fix agents get only the brief and edit blind at `haiku` — never tell them to re-read files, test suites, or `CLAUDE.md` and `AGENTS.md`. Reviewers check git diffs against the brief.

web/src/lib/endpoints.ts: 1
937-938: Data Integrity & Integration
The UID header is applied to file writes and deletes, as the documented contract states. Directory listings are not UID-guarded by design. A stale listing can show entries from a replaced server. The listing does not write, and a later write from the same view is rejected with 409. This is a freshness issue in a read-only view, not a data-integrity or authorization failure. The proposed concern does not establish a defect that the change needs to fix.
web/src/lib/fileDrafts.ts: 1
81-87: Security & Privacy
The sign-out path does not carry cached drafts to a later session. Both logout handlers navigate with location.assign("/login"), which reloads the document. The app-level QueryClient lives in memory and is not persisted, so the reload discards the editor-drafts entry and its FileDrafts instance. The stated premise, that sign-out keeps the same query client, does not hold in the inspected code. The key may not include the user identity, but the cache does not survive into another account's session through these paths.
agent/internal/files/archive_linux.go: 1
162-162: Stability & Availability
The openFile call at archive_linux.go:162 cannot block on a FIFO. The shared fileFlags include O_NONBLOCK, so the open returns immediately without waiting for a writer. The regular-file check that follows then rejects the entry. Archive requests do not stall, and no 409 results from this path.
api/cmd/main.go: 1
900-900: Stability & Availability
The comment's premise is contradicted. The archive proxy's HTTP client has no total Timeout. The direct transport is built with timeout 0 at api/internal/ws/dialer.go:46, and the gateway client sets no client-level Timeout. The exemption at api/cmd/main.go:908 therefore does not expose archive transfers to a client-level deadline. The 15s timeout belongs to AgentClient, which the archive proxy does not use. The remaining ResponseHeaderTimeout on the gateway path bounds only header arrival and has no shown consequence for streaming. No publishable finding remains.

Reviewed editor drafts, path-based navigation, UID-scoped reads and downloads, and archive publication. The regression cases cover failed deletion with a pending autosave, a late read after deletion, navigation during file creation, normalized paths, and archive collisions. A real Chrome/Monaco run verified direct navigation, editing, namespaced autosave and reopening on desktop and mobile. The archive path uses descriptor-relative no-follow opens and atomic publication. The Files screen and Create ZIP dialog have refreshed Pencil exports.
