Add the Grok harness with its hooks and setup

[realtonyyoung]

Closes #1421 — AI-3650, part of AI-3651

What & why

Adds Grok Build as harness grok. kcap setup / kcap plugin install --grok write a kcap-owned ~/.grok/hooks/kcap.json (creating ~/.grok/hooks/, which a fresh Grok lacks) that runs kcap hook --grok on SessionStart and Stop. Session start posts /hooks/session-start/grok and starts the watcher on the session's updates.jsonl, whose path is derived from the percent-encoded cwd, with a .cwd-file lookup past 255 bytes. Stop restarts a missing watcher from the payload's transcriptPath. The watcher reads Grok's ACP session/update lines for titles. kcap import --grok imports past sessions from ~/.grok/sessions/, each subagent through the parent that spawned it.

Where to look

There is no SessionEnd hook: Grok allows it 1.5 s, and the watcher already ends the session after its final drain once grok exits. --tools-only is refused for Grok because kcap installs no tools for it; Grok loads the MCP servers set up for Claude Code.

Verification

• Payload shapes come from a live Grok 1.0.52 run with a capture hook: camelCase keys, snake_case event values, transcriptPath on every event except session start, and the hook's parent process named grok.
• GrokHookCommandTests (WireMock): session start posts the session and spawns a vendor=grok watcher on the derived path; a 400 spawns nothing and still exits 0; Stop respawns without posting; other events do nothing.
• Unit tests cover path derivation including the .cwd fallback, the installer's handler fields and idempotence, removal, and the watcher extractors. Setup, plugin, vendor-selection, status and registry conformance pins all pass with Grok.
• GrokImportSourceTests and GrokImportTests: discovery, title and cwd, and a subagent imported under its parent; SetupImportLaneTests pins an import source for every harness.
• dotnet publish -c Release: no IL2xxx/IL3xxx warnings.

📝 Walkthrough

The change adds Grok as a supported harness. It connects Grok detection, hook installation and dispatch, session watching, historical session and subagent import, plugin lifecycle commands, and hosted-catalog configuration.

Changes: Grok harness integration

Layer / File(s)	Summary
Harness identity and paths src/Capacitor.Cli.Core/Harness/*, src/Capacitor.Cli.Daemon/*, src/Capacitor.App/Services/HostedHarnessCatalog.cs, test/Capacitor.Tests.Helpers/TestHarnesses.cs	The harness registry, daemon configuration, hosted catalog, and test harnesses include Grok. GrokPaths resolves Grok directories and session update paths.
Setup and plugin lifecycle src/Capacitor.Cli/Commands/{CodingAgentsStep,SetupCommand,SetupDecisions,PluginCommand,VendorSelection,UninstallCommand,RefreshCommand}.cs, src/Capacitor.Cli.Core/Resources/*, README.md	Setup detects Grok and supports --skip-grok-hooks. Plugin commands install, refresh, and remove Grok hooks. Grok is excluded from tools-only installation. Help text and README document Grok setup, plugin, and import options.
Hook installation and dispatch src/Capacitor.Cli.Core/Harness/Grok/GrokHooksInstaller.cs, src/Capacitor.Cli/Commands/Harness/GrokHookCommand.cs, src/Capacitor.Cli/Commands/{CommandServices,Program}.cs, test/Capacitor.Cli.Core.Tests.Unit/Harness/Grok/GrokHooksInstallerTests.cs, test/Capacitor.Cli.Tests.Integration/GrokHookCommandTests.cs	The installer writes Grok hook entries. The CLI dispatches hook --grok; the command posts session-start data and starts or restarts a watcher when a transcript path is available.
Grok session update watching src/Capacitor.Cli/Commands/WatchCommand.cs, test/Capacitor.Cli.Tests.Unit/Harness/Grok/GrokWatchExtractorTests.cs, test/Capacitor.Cli.Tests.Unit/Commands/WatchCommandTests.cs	The watcher extracts Grok user and agent message chunks, counts those chunks as conversational events, and skips transcript-threshold buffering for Grok.
Historical session and subagent import src/Capacitor.Cli/Harness/Grok/*, src/Capacitor.Cli.Core/Harness/Grok/GrokSubagentEvent.cs, src/Capacitor.Cli.Core/Harness/Grok/GrokSubagents.cs, src/Capacitor.Cli/Commands/SetupCommand.cs, test/Capacitor.Cli.Tests.Integration/GrokImportTests.cs, test/Capacitor.Cli.Tests.Unit/Harness/Grok/GrokImportSourceTests.cs, test/Capacitor.Cli.Tests.Unit/Harness/Grok/GrokSubagentsTests.cs, test/Capacitor.Cli.Tests.Unit/Commands/ReplayChildContentCapabilityTests.cs	The import source discovers and classifies Grok sessions, sends transcript batches, and replays subagents through parent sessions.

Merge Risk: ⚪ Minimal · up to da891

No actionable merge-blocking risk remains in the reviewed incremental changes.

Security architecture risk: 🔵 Low · up to da891

The integration reuses the existing authenticated capture flow and privacy controls. No introduced security vulnerability was established, but production ownership enforcement and recovery after interrupted imports remain unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The demonstrated client-side exposure is local session and child transcript content submitted to the configured server through the existing command client. An adversary influencing these requests would need influence over the local recordings or the authenticated caller. GUID validation constrains lexical child paths, but does not prove filesystem-link containment or server-side account and parent-child isolation.

Trust Boundaries and Controls

• observed — Historical import selects the existing command client rather than the anonymous discovery client, and passes that client into classification and routed import. Child transcript delivery is gated on successful registration. These client controls do not establish server authorization for supplied session and agent identifiers.
• observed — Grok applies the shared visibility stamp on session creation. Under --private, the existing dispatcher attempts to narrow partial and already-loaded sessions before uploading, and removes sessions whose privacy write failed from routed import. This is counterevidence to a new Grok-specific privacy-control bypass.

Resilience and Maintainability Implications

• observed — The source checks cancellation between children and during watermark requests, but transcript batching has no cancellation-token parameter and the lifecycle POST wrapper converts exceptions to failure. The inspected command currently invokes routed import with CancellationToken.None. This does not establish a newly bypassed user cancellation control, although interruption and concurrent replay still depend on server recovery guarantees.

Hardening Proposals

• proposed — Validate the production endpoint contract for authenticated account and parent-child binding, duplicate lifecycle and transcript requests, concurrent watermark updates, and recovery after interruption. Treat this as closure of the remaining proof gap, not as a verified authorization or recovery vulnerability.

High-Level Assessment

The following are alternative approaches to this PR:

1. End sessions in a SessionEnd hook

• ➕ Would make session termination explicitly hook-driven.
• ➖ Grok’s 1.5-second hook allowance is too short for the watcher’s final drain.

2. Merge hooks into another agent’s configuration

• ➕ Could reuse existing hook installation code.
• ➖ Would couple Grok recording to another agent and complicate ownership and removal.

Recommendation: Keep Grok’s separate, kcap-owned hook file and watcher-driven session end. They match Grok’s hook loading and time limit while preserving other agents’ configurations.

2. Grok transcripts lose their content ⊘ Outdated

Description

The watcher sends Grok's ACP session/update lines as transcript data, but kcap-server has no Grok
normalizer and falls back to its Claude normalizer. When those lines reach ingest, the Claude
normalizer finds no top-level type and produces no canonical message events; session-end cleanup
can then delete the session as trivial.

Code

src/Capacitor.Cli/Commands/WatchCommand.cs[R2905-2908]

+            if (root.Str("method") != "session/update") return null;

4. Grok session starts fail body binding ✗ Dismissed

Description

StartRecording derives transcriptPath but omits both transcript_path and source from its
forwarded session-start JSON. When Grok uses the generic session-start route, the server binds a
Claude-shaped record requiring transcript_path, so binding can fail before a session is created or
the watcher is spawned.

Code

src/Capacitor.Cli/Commands/Harness/GrokHookCommand.cs[R72-77]

+        var forwarded = new JsonObject {
+            ["hook_event_name"] = "SessionStart",
+            ["session_id"]      = sessionId,
+            ["cwd"]             = cwd ?? "",

Evidence

The Grok CLI derives a transcript path but forwards only hook_event_name, session_id, cwd and
home_dir; its WireMock test accepts any body and would not catch a binding failure. The server’s
generic session-start route binds a DTO that inherits the required transcript_path field from
HookBase, while the Mistral Vibe hook and its import source identify transcript_path and
source as fields needed for that route.

Alternatively, coordinate a Grok-specific server DTO that does not require `transcript_path`.

5. Grok sessions omit machine inventory and platform ✗ Dismissed

Description

StartRecording never calls SessionStartInventory.Stamp, but every other harness's session-start
path does. Because of that, Grok session-start bodies carry no harness_inventory and no
platform. With no platform, the server excludes platform-restricted facts for these sessions, and
a machine without a daemon reports no harness inventory through Grok.

Code

src/Capacitor.Cli/Commands/Harness/GrokHookCommand.cs[R81-83]

+        if (activeProfile?.DefaultVisibility is { } visibility) forwarded["default_visibility"] = visibility;
+
+        var enriched = await RepositoryDetection.EnrichWithRepositoryInfo(router, config, forwarded.ToJsonString(), clock.Time);

Relevance

●●● Strong

Omitting shared session-start inventory metadata breaks established cross-harness behavior and
server-side fact eligibility.

Evidence

Each of the other ten hook commands calls SessionStartInventory.Stamp, and that method is what
adds harness_inventory and platform. Its comment says an unknown platform excludes
platform-restricted facts server-side.

6. Stop can capture a rejected session ✓ Resolved

Description

GrokHookCommand starts a watcher on stop whenever none is alive, without checking whether the
session-start POST was accepted. If that POST returned a failure and correctly suppressed its
watcher, a later Stop bypasses that decision and starts watching the rejected session.

Code

src/Capacitor.Cli/Commands/Harness/GrokHookCommand.cs[R65-66]

+            case "stop" when !watchers.IsWatcherAlive(sessionId):
+                await EnsureWatcher(sessionId, transcriptPath, cwd, skipTitle: true);

7. Browser setup cannot offer Grok ⊘ Outdated

Description

HarnessRegistry now reports Grok to browser-based setup, but kcap-server's ReadFacts discards
vendors absent from FirstRunHarnessCatalog, which has no Grok entry. When a Grok user follows that
setup path, the Agents screen cannot offer Grok recording, so its answer cannot select the new hook
install.

8. Unreadable hooks file breaks refresh ✓ Resolved

Description

GrokHooksInstaller.IsInstalled reads the hooks file but catches only JsonException, allowing
filesystem read failures to escape. When plugin install --grok --if-installed encounters an
existing file that has become unreadable, the refresh terminates with an unhandled exception instead
of a controlled result.

Code

src/Capacitor.Cli.Core/Harness/Grok/GrokHooksInstaller.cs[R61-64]

+            return JsonNode.Parse(File.ReadAllText(hooksPath))?["hooks"] is JsonObject hooks

9. Long paths with spaces lose Grok capture ✓ Resolved

Description

SlugDirFor calls Trim() on the .cwd contents before comparing them with the actual cwd,
removing legitimate trailing spaces. For a cwd whose encoded name exceeds 255 bytes and ends in a
space, the lookup returns no transcript path, so the session-start hook cannot start its watcher.

Code

src/Capacitor.Cli.Core/Harness/Grok/GrokPaths.cs[49]

+                if (File.Exists(marker) && File.ReadAllText(marker).Trim() == cwd) return dir;

11. Upgrades leave Grok hooks unrefreshed ✓ Resolved

12. Empty Grok homes go undetected ✗ Dismissed

Description

GrokPaths.HasUserData() returns true only when config.toml or sessions exists beneath the Grok

not detected even though the directory condition is satisfied.

13. Long-path Grok sessions skip session start ✓ Resolved

Description

DispatchAsync returns before posting session start when UpdatesJsonl returns null. That happens
when the percent-encoded cwd is longer than 255 bytes and no folder under sessions/ yet has a
matching .cwd file. So the first session in a deep working directory can post no session start,
and a later Stop then spawns a watcher for a session the server never got a start for.

Code

src/Capacitor.Cli/Commands/Harness/GrokHookCommand.cs[R57-59]

+        var transcriptPath = Str(node, "transcriptPath")
