You are running ON debian1, a buildbox, deliberately — the owner's laptop is saturated and this work must NOT run there. Keep all compute on this box.

TASK: fix the land authority-file race that is currently failing every land in the overdeck repo.

Repo mirror on this box: /home/user/builds/overdeck-f7f63179e1c7 (git). Fetch origin first; work on a branch.

THE BUG (root-caused on the laptop, evidence below — do not re-derive it, verify and fix it):
- File: modules/workstation/claude/workflows/lib/finish-branch.sh, around lines 786-815.
- It generates a nonce, writes it to the SINGLE shared path "$common_dir/harness/land-authority", then runs: HARNESS_LAND_TOKEN=$nonce git push origin "$candidate_ref:refs/heads/main".
- The pre-push hook (repo core.hooksPath -> .git/harness/hooks/pre-push, lines 28-40) compares HARNESS_LAND_TOKEN against the contents of that file.
- With concurrent landers, lander B does `rm -f authority` + writes ITS nonce in the window between lander A's write and A's push. A's hook then reads B's nonce, mismatches, and rejects with "pre-push: rejected — unauthorized main update".
- The lander records this as {"status":"push-failed","detail":"plain candidate push to origin main failed"}, which reads like a remote problem and is actually local mutual exclusion failing.
- PROOF collected: auth is fine (`git push --dry-run origin main:refs/heads/main` -> "Everything up-to-date", exit 0); no remote churn (main == origin/main == ls-remote == 1740d0dd at failure time, so the retry branch at :806-813 never fires); the real rejection text was reproduced by building an equivalent candidate and dry-run pushing it.

FIX, both parts:
1. Remove the race structurally. Preferred: per-push authorization so two landers cannot share a slot — the writer creates "land-authority.<nonce>" and the hook checks for the file named by $HARNESS_LAND_TOKEN (atomic creation, no clobber window, and a stale file authorizes nothing because the nonce is unguessable). A flock around write->push->cleanup is acceptable if you can show it covers EVERY writer. Whichever you choose, the hook and the lander must change together and stay consistent.
2. Stop discarding the push error. Line ~799 pushes with >/dev/null 2>&1 and throws away the hook's exact, actionable reason. Capture stderr and put it in the verdict detail.

PROVE IT with a test in modules/workstation/claude/tests/ (test-finish-branch.sh is the existing suite, 97 tests): two landers overlapping must both succeed, or fail for an honest reason — never reject each other. Run the whole suite and report pass/fail counts.

ALSO CHECK: every writer of main must go through the land queue. Merges on main titled "harness: land wt/..." suggest a harness path that may push outside the queue. If one bypasses it, that is the serialization hole — report it precisely.

DELIVERY: commit on a branch and push it to origin (gh is installed here; if push credentials are missing on this box, say so explicitly and stop — do NOT try to route the work back to the laptop). Report the branch name so the land can be driven from the laptop.

ABSOLUTE RULES: never push or force-push main by hand. Never run a fork-bomb/exhaustion/destructive test anywhere. Never kill a process by name. Do not touch this box's sshd or network config — two buildboxes were bricked today. Fix or explicitly justify every warning.

addedTypes: claude code-reviewer dead-advisor Explore general-purpose Plan security-guard statusline-setup

addedLines: - claude: Catch-all for any task that doesn't fit a more specific agent. FleetView's default when no agent name is typed. (Tools: *)

addedLines:
- code-reviewer: Use this agent when a major project step has been completed and needs to be reviewed against the original plan and coding standards. Examples: <example>Context: The user is creating a code-review agent that should be called after a logical chunk of code is written. user: "I've finished implementing the user authentication system as outlined in step 3 of our plan" assistant: "Great work! Now let me use the code-reviewer agent to review the implementation against our plan and coding standards" <commentary>Since a major project step has been completed, use the code-reviewer agent to validate the work against the plan and identify any issues.</commentary></example> <example>Context: User has completed a significant feature implementation. user: "The API endpoints for the task management system are now complete - that covers step 2 from our architecture document" assistant: "Excellent! Let me have the code-reviewer agent examine this implementation to ensure it aligns with our plan and follows best practices" <commentary>A numbered step from the planning document has been completed, so the code-reviewer agent should review the work.</commentary></example>
 (Tools: All tools)

addedLines:
- dead-advisor: Fallback for the built-in `advisor` tool when its API is failing. A reusable, session-persistent stronger-reviewer (opus, xhigh effort) that reconstructs the main agent's full conversation from the on-disk transcript and gives the same critical advice the `advisor` tool would. Spawn via the `/dead-advisor` skill, then continue across the session via SendMessage. Do NOT invoke directly — the skill supplies the disambiguating transcript marker this agent needs.
 (Tools: All tools)

addedLines: - Explore: Read-only search agent for broad fan-out searches — when answering means sweeping many files, directories, or naming conventions and you only need the conclusion, not the file dumps. It reads excerpts rather than whole files, so it locates code; it doesn't review or audit it. Specify search breadth: "medium" for moderate exploration, "very thorough" for multiple locations and naming conventions. (Tools: All tools except Agent, Artifact, ExitPlanMode, Edit, Write, NotebookEdit)

addedLines: - general-purpose: General-purpose agent for researching complex questions, searching for code, and executing multi-step tasks. When you are searching for a keyword or file and are not confident that you will find the right match in the first few tries use this agent to perform the search for you. (Tools: *)

addedLines: - Plan: Software architect agent for designing implementation plans. Use this when you need to plan the implementation strategy for a task. Returns step-by-step plans, identifies critical files, and considers architectural trade-offs. (Tools: All tools except Agent, Artifact, ExitPlanMode, Edit, Write, NotebookEdit)

addedLines:
- security-guard: Independent, adversarial pre-ship / pre-merge security + correctness review of a specific file, route, or diff. Invoke as a FRESH cross-context pass — especially after a self-audit has "converged" or a change is about to ship — to catch what a self-review stops looking for: object-level authorization (IDOR), fail-open auth/crypto paths, side-channel/timing oracles, injection, SSRF, DoS, idempotency/atomicity, content-type confusion, and info-disclosure defects. Give it the exact file(s) or diff to review. Language- and platform-agnostic — works on any codebase with a trust boundary (web/API, CLI, library/SDK, mobile or desktop backend, infra/IaC, data pipeline, smart contract).

<example>Context: a change is about to merge after the author already reviewed it. user: "complete.ts is ready to ship — the attachment upload route." assistant: "Before merge, let me run the security-guard agent as an independent adversarial pass over complete.ts." <commentary>Pre-ship gate on a specific route — the security-guard's core job is the fresh-eyes catch the author's converged review missed.</commentary></example>
<example>Context: a multi-wave audit reported clean. user: "the audit converged, no more P0/P1." assistant: "Convergence on a self-audit is exactly when a fresh independent pass earns its place — running security-guard over the changed routes." <commentary>The documented failure mode: a converged self-audit stops hunting; an independent pass finds the residual miss.</commentary></example>
 (Tools: All tools)

addedLines: - statusline-setup: Use this agent to configure the user's Claude Code status line setting. (Tools: Read, Edit)


content:
- agent-doc-authoring: Use when writing or editing any document AI agents will read — CLAUDE.md, AGENTS.md, specs, standards, plans, skill files (SKILL.md), subagent/system prompts. Also when a doc carries private codenames or nicknames, reads as prose narrative instead of imperatives, or needs naming/wording decisions for an agent audience. Read before writing the doc; check the diff against it before declaring the doc done.
- agentify-doc: Rewrite, compress, tighten, condense, shorten, or "agentify" an existing agent-facing doc (SKILL.md, CLAUDE.md, spec, standard, plan, system prompt) that is verbose or token-bloated. Triggers on "make this leaner for agents", "cut tokens from this doc", "rewrite this skill concisely", "tokenomics", "agentify".

- dataviz: Use this skill whenever you are about to create ANY chart, graph, plot, dashboard, or data visualization, in ANY output medium — an HTML or React artifact, inline SVG, plotting code in any library (matplotlib, plotly, d3, Recharts, …), an image/PNG you will render and upload, or a chart shared into Slack. Read it BEFORE writing the first line of chart code, choosing chart colors, building a stat tile / meter / KPI row, or laying out a dashboard. Produces visualizations that read as one system — elegant, accessible, consistent in light and dark — using a brand-neutral placeholder palette you swap for your own. Teaches a design-system-agnostic method: a form heuristic, a color formula with a runnable validator, mark specs, and interaction rules. A validated default palette is documented in `references/palette.md` — swap that file's values for your brand's. Triggers on: "chart", "graph", "plot", "data viz", "visualization", "dashboard", "analytics", "visualize data", "categorical colors", "sequential / diverging palette", "stat tile", "sparkline", "heatmap", "legend", "axis", "tooltip", "chart colors", "color by series".
- update-config: Use this skill to configure the Claude Code harness via settings.json. Automated behaviors ("from now on when X", "each time X", "whenever X", "before/after X") require hooks configured in settings.json - the harness executes these, not Claude, so memory/preferences cannot fulfill them. Also use for: permissions ("allow X", "add permission", "move permission to"), env vars ("set X=Y"), hook troubleshooting, or any changes to settings.json/settings.local.json files. Examples: "allow npm commands", "add bq permission to global settings", "move permission to user settings", "set DEBUG=true", "when claude stops show X". For simple settings like theme/model, suggest the /config command.
- keybindings-help: Use when the user wants to customize keyboard shortcuts, rebind keys, add chord bindings, or modify ~/.claude/keybindings.json. Examples: "rebind ctrl+s", "add a chord shortcut", "change the submit key", "customize keybindings".
- simplify: Review the changed code for reuse, simplification, efficiency, and altitude cleanups, then apply the fixes. Quality only — it does not hunt for bugs; use /code-review for that.
- fewer-permission-prompts: Scan your transcripts for common read-only Bash and MCP tool calls, then add a prioritized allowlist to project .claude/settings.json to reduce permission prompts.
- loop: Run a prompt or slash command on a recurring interval (e.g. /loop 5m /foo). Omit the interval to let the model self-pace. - When the user wants to set up a recurring task, poll for status, or run something repeatedly on an interval (e.g. "check the deploy every 5 minutes", "keep running /babysit-prs"). Do NOT invoke for one-off tasks.
- claude-api: Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration.
TRIGGER — read BEFORE opening the target file; don't skip because it "looks like a one-liner" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answer from memory; OR the task is LLM-shaped with provider unstated (agent/MCP/tool-definition/multi-agent/RAG/LLM-judge/computer-use; generate/summarize/extract/classify/rewrite/converse over NL; debugging refusals/cutoffs/streaming/tool-calls/tokens).
SKIP only when another provider is being worked on (overrides all triggers): OpenAI/GPT/Gemini/Llama/Mistral/Cohere/Ollama named in the query; OR `grep -rE 'openai|langchain_openai|google.generativeai|genai|mistralai|cohere|ollama'` over the project hits (run this grep FIRST if no provider named — don't Read the file).
- run: Launch and drive this project's app to see a change working. Use when asked to run, start, or screenshot the app, or to confirm a change works in the real app (not just tests). First looks for a project skill that already covers launching the app; otherwise falls back to built-in patterns per project type (CLI, server, TUI, Electron, browser-driven, library).
