llm-tracker

A Kanban board for LLMs to keep their humans up to date.

Stop forcing your LLMs to re-read and rewrite massive architecture files just to update a status. llm-tracker is a 100 % local mission-control center that bridges the gap between complex agentic workflows and human oversight.

It's a file-system-as-database tracker. Your LLMs update project states with tiny HTTP or file-based patches, and the local hub renders a live, calm terminal-style priority matrix so you can see exactly what your agents are doing at a glance.

When an agent needs to answer "what should I do next?", it can now make one call to npx llm-tracker next <slug> or GET /api/projects/<slug>/next and get a ranked shortlist instead of re-reading the full tracker. The ranking prefers bounded actionable work over aggregate roadmap/container rows, and prefers continuing active bounded work over starting a fresh bounded task.

When a human or agent asks "what about the feature with the..." instead of naming a task id, the hub now exposes both GET /api/projects/<slug>/search?q=... for local embedding-backed semantic search and GET /api/projects/<slug>/fuzzy-search?q=... for deterministic fuzzy lexical matching. Both modes are reachable from the UI through the global ⌘K command palette (prefix ~ for fuzzy, ? for semantic).

When an agent already knows the task id and needs focused context, it can now make one call to npx llm-tracker brief <slug> <task-id> or GET /api/projects/<slug>/tasks/<taskId>/brief and get a capped pack instead of rereading the tracker, docs, and code by hand.

When an agent needs to answer "why does this task exist?" or "what decisions did we already make?", it can now call npx llm-tracker why <slug> <task-id> or npx llm-tracker decisions <slug> instead of reconstructing that from raw comments and history.

When an agent is ready to act or validate work, it can now call npx llm-tracker execute <slug> <task-id> and npx llm-tracker verify <slug> <task-id> for deterministic execution and verification packs instead of inventing a plan from scratch.

When an agent needs the current contract for a running hub, it should call GET /help first instead of guessing write modes or endpoints.

The UI exposes the same deterministic loop for humans through the refined Variant A2 layout:

• Top bar — project name with ▾ quick-switch, rev badge, agent cluster ([NEXT], [BLOCKERS], [CHANGED], [DECISIONS]), history cluster ([UNDO], [REDO]), the ⌘K palette input, and a ⋯ overflow menu for retired actions (collapse/expand all lanes, open overview, settings, help, theme toggle, delete project).
• Hero strip — big progress headline, 2×3 status grid, and a green Recommended Next callout with [PICK] and [READ] buttons sourced from /next?limit=1.
• One-line scratchpad — a NOTE row with [EXPAND] to read the full note and [EDIT] for an inline textarea (cmd+enter saves).
• Swimlane/tree/graph view toggle — the filter row includes [SWIMLANE], [TREE], and [GRAPH]; tree view uses explicit kind: "group" / parent_id hierarchy when present and falls back to swimlanes as top-level groups.
• Dependency graph view — a derived UI projection over existing dependencies[] blocker edges. It does not add schema or data fields, and its optional [CONTAINMENT] overlay draws parent_id tree/group edges as a visual aid only.
• Task cards — three tiers (id + title, summary, status/assignee/tags) with a [READ]/[WHY]/[EXEC]/[VERIFY] bracket row. Clicking a card expands an inline drawer in place (brief by default; [WHY]/[EXEC]/[VERIFY] tabs render their own packs without leaving the board).
• ⌘K command palette — projects + tasks + retired header actions (filter, fuzzy via ~, semantic via ?, jump-to-next, collapse/expand all, undo/redo, theme toggle, settings, help).
• Themes — calm warm-paper light and calibrated dark, both from the same token set; toggle from the ⋯ menu.

Loading

All write paths converge on the Store under a per-slug lock; the hub is the sole arbiter of merge and revision stamping. See ARCHITECTURE.md for the full contract.

Why use llm-tracker?

🔒 100 % Local & Secure — the core hub doesn't ping any LLM APIs; it watches your local filesystem, merges patches, and serves the UI. Your project state never leaves your machine. Semantic /search uses a local embedding model and only reaches out once if the model is not already cached on disk.

The hub binds to 127.0.0.1 by default, rejects cross-origin mutating requests, and supports an optional bearer token (LLM_TRACKER_TOKEN) that gates every write without exposing the raw secret to the browser UI. See Local security for the full threat model and override knobs.

💸 Massive Token Savings — no full-file rewrites. LLMs send surgical JSON patches (often <100 bytes) and pull changes since their last rev, keeping context windows small and API costs low.

⚡ Stupidly Simple — no databases, no cloud accounts, and no behavior surprises. npx llm-tracker init, npx llm-tracker, open the browser. Foreground remains the default; an optional local background daemon is available if you do not want to dedicate a shell. Every project is one JSON file you can cat, diff, or commit.

Screenshots

Main view — top bar, hero strip (progress + status grid + Recommended Next), one-line NOTE scratchpad, and the swimlane × priority board with an alternate task tree view.

Task comments — each task has an optional comment field (≤ 500 chars). Set it via JSON, patch API, or the inline [+C] editor on the card; hover the [C] badge to read it. The popover clamps to the viewport so cards near the edges don't clip.

Overview drawer — all projects at a glance; click to switch, pin to keep it open. Also reachable from the project-name ▾ dropdown and the ⋯ overflow menu.

Drag and drop — re-prioritize or move tasks across swimlanes; hub writes atomically, UI updates live. The dragged card lifts with a soft shadow and valid drop cells show a dashed highlight.

Dark (default) and light themes — both calibrated from the same A2 token set; toggle from the ⋯ overflow menu. Body text meets WCAG AA at 14.5px in both themes.

Install (30 seconds)

npx llm-tracker init     # scaffolds ~/.llm-tracker workspace
npx llm-tracker          # starts hub + UI on http://localhost:4400
npx llm-tracker --daemon # same hub, but detached into the background

The first command prints a paste-ready prompt. Give it to any LLM with file-write or HTTP access, and your project appears in the UI within half a second.

Or install globally once:

npm install -g llm-tracker
llm-tracker init && llm-tracker

Day 0 project skeleton

Every tracker is one JSON file with two top-level keys: meta and tasks. The minimal shape the hub accepts — copied from workspace-template/templates/default.json — is:

{
  "meta": {
    "name": "New Project",
    "slug": "new-project",
    "swimlanes": [
      { "id": "main", "label": "Main" }
    ],
    "priorities": [
      { "id": "p0", "label": "P0 / Now" },
      { "id": "p1", "label": "P1 / Next" },
      { "id": "p2", "label": "P2 / Soon" },
      { "id": "p3", "label": "P3 / Later" }
    ],
    "scratchpad": ""
  },
  "tasks": []
}

Drop this at <workspace>/trackers/<slug>.json (with meta.slug matching the filename) and the hub renders it immediately. Field-by-field contract → ARCHITECTURE.md.

Tasks may also opt into tree grouping with kind: "group" and parent_id. parent_id is containment only; execution blockers still belong in dependencies. Groups can nest by pointing one group at another group through parent_id. If a tracker has no explicit groups or parents, tree view treats swimlanes as the root groups. Tree display order is swimlane, then priority, then the hub-owned task array order.

The dependency graph view, when shown, is derived from those same dependencies[] blocker edges. It is display-only: it does not introduce new task fields, graph fields, or alternate containment semantics. The graph's optional [CONTAINMENT] overlay can draw parent_id tree/group edges as dashed visual context; those overlay edges do not affect block state or execution order.

Supported Topologies

llm-tracker supports two deployment shapes:

• Recommended: one shared workspace + one shared daemon + many linked projects. Run the hub on a central workspace such as ~/.llm-tracker, then link repo-local tracker files into it with npx llm-tracker link <slug> <abs-path>. This gives one source of truth for humans and agents.
• Supported: multiple isolated workspaces + multiple daemons. Useful for demos, sandboxes, or teams that want hard isolation. Each daemon needs its own workspace folder and port.

If you keep a tracker file in a repo and link it into the shared workspace:

• the shared daemon automatically watches the linked tracker file for direct edits
• the shared daemon automatically watches the shared workspace patches/ directory
• patch files belong in the shared workspace, not in the repo-local .llm-tracker/ folder
• the repo-local tracker JSON is a linked durable target of the shared hub, not branch-local scratch state or a merge artifact
• durable tracker writes still land on the linked repo-local tracker file itself; that is sync, not relocation
• if that linked tracker JSON is versioned inside the repo, expect successful patch writes that change durable fields to update the repo-visible JSON file in place
• linked trackers now split high-churn runtime state into the shared workspace overlay at .runtime/overlays/<slug>.json
• for linked trackers, runtime churn such as task status, assignee, blocker_reason, plus meta.scratchpad, updatedAt, and rev no longer needs to dirty the repo-visible JSON
• durable tracker edits still update the linked repo-local JSON in place, and GET /api/projects/<slug> / successful patch responses expose that durable path as file
• never use git restore, git checkout, git stash, or merge-conflict cleanup as a tracker update mechanism; verify with /help or GET /api/projects/<slug>, then use tracker_patch, tracker_pick, tracker_reload, or the equivalent HTTP endpoints

Landing gate. For linked repo-local trackers, patch the tracker before you commit or push the matching code, and include the tracker JSON diff in the same commit. Patching after a commit/push leaves the working tree dirty; patching after a squash-merge dirties main. Pure runtime fields (status, assignee, blocker_reason, meta.scratchpad, updatedAt, rev) already route through the runtime overlay and do not dirty the repo JSON — those are safe to touch anytime. See the agent contract at /help for the full rule.

Before push or merge, prove .llm-tracker/trackers/hoplon.json on the branch contains the live tracker truth for the touched tasks. Compare tracker_brief against the repo file and against origin/main. Do not restore, stash, or discard tracker diffs. If merging would regress tracker truth, stop and make a tracker-sync commit/PR first.

Agent Help

For agents. The authoritative contract LLMs should follow is workspace-template/README.md, which is served live at GET /help. If you are an agent / LLM, read that file (or call /help) rather than this one.

Running hubs expose GET /help as the current agent contract for that workspace.

• It serves the workspace README.md
• For standard workspaces, that file comes from workspace-template/README.md
• Agents should read /help before using write paths or task-intelligence endpoints
• Agents should prefer next to choose work, brief to load task context, why to explain task intent, decisions to recall prior decisions, and execute / verify to close the work loop before broad file reads
• If you change agent-facing behavior, update the workspace template so /help stays accurate

Wire it into your LLM CLI

Drop a one-line file into your coding CLI's rules/skills folder. That's the whole install. Next time you ask "what's the state of my projects?" the LLM runs npx llm-tracker status on its own.

That path is still prompt-driven. It saves rereads, but it still spends model tokens.

Claude Code — create ~/.claude/skills/llm-tracker-status/SKILL.md:

---
description: Show overall status of LLM Project Tracker projects.
---

When the user asks about project status, progress, or what the tracker shows, run:

    npx llm-tracker status

For one project in detail: `npx llm-tracker status <slug>`.
For JSON (chainable): `npx llm-tracker status --json`.

Every other CLI — one sentence pointing at the same command:

Environment	Drop the line at
Cursor	.cursor/rules/llm-tracker.md
Windsurf	append to .windsurfrules
Aider	append to CONVENTIONS.md
Anything else	AGENTS.md in the repo root

Each file just says: "For project status, run npx llm-tracker status." That's it.

If the hub is already running, add one more line: "Before using the tracker, read GET /help."

---

Zero-token terminal shortcut

If you want direct tracker commands from a Codex or Claude terminal session without asking the model anything, print the shell wrapper once and load it into your shell:

eval "$(npx llm-tracker shortcuts)"

The default short alias for llm-tracker is lt. That command creates a small lt shell function. Use it like:

lt next project-phalanx
lt brief project-phalanx t-021
lt why project-phalanx t-021
lt execute project-phalanx t-021
lt verify project-phalanx t-021

To keep it permanently, append the printed snippet to ~/.zshrc or ~/.bashrc. If you want a different function name, use npx llm-tracker shortcuts --alias tracker.

HTTP API Quick Reference

The HTTP hub is the clean machine interface for agent clients.

Start with:

curl http://localhost:4400/help

That returns the active workspace contract for the running hub. In daemon mode on another port, use the port recorded in .runtime/daemon.json or npx llm-tracker daemon status.

Core read endpoints

# Workspace / project overview
curl http://localhost:4400/help
curl http://localhost:4400/api/projects
curl http://localhost:4400/api/projects/<slug>
curl "http://localhost:4400/api/projects/<slug>/next?limit=5"
curl "http://localhost:4400/api/projects/<slug>/since/<rev>"

# Focused task context
curl http://localhost:4400/api/projects/<slug>/tasks/<taskId>/brief
curl http://localhost:4400/api/projects/<slug>/tasks/<taskId>/why
curl http://localhost:4400/api/projects/<slug>/tasks/<taskId>/execute
curl http://localhost:4400/api/projects/<slug>/tasks/<taskId>/verify

# Project-level context
curl "http://localhost:4400/api/projects/<slug>/decisions?limit=20"
curl http://localhost:4400/api/projects/<slug>/blockers
curl "http://localhost:4400/api/projects/<slug>/changed?fromRev=<rev>&limit=20"
curl "http://localhost:4400/api/projects/<slug>/history?limit=50"

# Search
curl "http://localhost:4400/api/projects/<slug>/search?q=<query>"
curl "http://localhost:4400/api/projects/<slug>/fuzzy-search?q=<query>"

Use search for feature-shaped questions and fuzzy-search when you want a deterministic lexical fallback.

Core write endpoints

Use HTTP writes when you want to avoid touching the workspace filesystem.

# Atomic claim / pick
curl -X POST http://localhost:4400/api/projects/<slug>/pick \
  -H "Content-Type: application/json" \
  -d '{"taskId":"<task-id>","assignee":"codex"}'

# Fire-and-forget project patch
curl -X POST http://localhost:4400/api/projects/<slug>/patch \
  -H "Content-Type: application/json" \
  --data-binary @/tmp/<slug>-patch.json

# Revision controls
curl -X POST http://localhost:4400/api/projects/<slug>/undo
curl -X POST http://localhost:4400/api/projects/<slug>/redo

# Reload trackers from disk
curl -X POST http://localhost:4400/api/projects/<slug>/reload

Successful POST /api/projects/<slug>/patch responses are authoritative immediately. They now return the accepted post-write rev, updatedAt, noop, and file (the effective tracker JSON path the hub wrote, which is the repo-local target for linked projects). When file points at a repo-local tracker, durable patch writes are expected to update that visible JSON file right away.

Patch payloads stay small. Typical shape:

{
  "tasks": {
    "t-001": {
      "status": "complete",
      "context": {
        "notes": "shipped"
      }
    }
  },
  "meta": {
    "scratchpad": "t-001 closed; t-002 is next"
  }
}

Practical rule of thumb

• Read /help first.
• Use next, brief, why, execute, and verify instead of rereading the whole tracker.
• Use patch for status/content updates.
• Use pick when you want an atomic claim instead of hand-rolling status changes.
• Keep writes small and frequent.

Agent Interfaces

This project ships a stdio MCP server via llm-tracker mcp.

Use the workspace contract first, then the narrowest interface that fits:

• read GET /help or tracker_help first for the active workspace contract
• use tracker_next, tracker_brief, tracker_why, tracker_decisions, tracker_execute, tracker_verify, tracker_search, and tracker_fuzzy_search for focused reads
• use tracker_patch, tracker_pick, tracker_undo, tracker_redo, and tracker_reload through the running hub for authoritative writes

Register the server in your client config instead of launching it manually:

[mcp_servers.llm-tracker]
command = "node"
args = [
  "/Users/you/path/to/llm-project-tracker/bin/llm-tracker.js",
  "mcp",
  "--path",
  "/Users/you/.llm-tracker",
]
startup_timeout_sec = 60

MCP reads work directly from workspace files. MCP writes still require the shared hub or daemon to be reachable.

Background daemon

Foreground startup is still the default. Existing users can keep using npx llm-tracker exactly as before.

If you want the hub to keep running without a dedicated shell, use npx llm-tracker --daemon or npx llm-tracker daemon start. Runtime artifacts live under ~/.llm-tracker/.runtime/ by default:

• daemon.json stores pid, port, and startup metadata
• daemon.log captures hub stdout and stderr

Existing workspaces do not need migration work. The .runtime/ directory is created on demand the first time daemon mode is used.

Hub-backed CLI commands reuse the active daemon port from .runtime/daemon.json when you omit --port, so brief, why, decisions, execute, verify, next, blockers, changed, pick, since, rollback, link, and reload keep working against a background hub started on a non-default port.

Daemon state is workspace-scoped. npx llm-tracker daemon stop --path <dir> only affects the daemon for that workspace. In the recommended shared-daemon topology, that means one daemon for the central workspace and linked repo-local project files underneath it.

Daemon troubleshooting

The hub now rescans tracker files on startup, eagerly loads trackers created through link, auto-reloads missing slugs on demand, and refreshes the project list from disk before serving /api/projects. In normal use, that should remove most "restart to see the project" failures.

If a tracker exists on disk but does not appear in the UI or a slug 404s unexpectedly:

1. If a specific slug 404s, retry the request once. The hub now attempts an on-demand reload for missing slugs.
2. Run npx llm-tracker reload [<slug>] --path <workspace> to rescan one slug or the whole workspace explicitly.
3. If it is a symlinked repo-local tracker, make sure it was registered through npx llm-tracker link ... rather than by manual symlink creation.
4. If the daemon itself looks stale, run npx llm-tracker daemon restart --path <workspace>.

If daemon stop times out or hub-backed commands say Hub not reachable:

1. Run npx llm-tracker daemon status --path <workspace> and npx llm-tracker daemon logs --path <workspace> --lines 120.
2. If the recorded PID still exists but the recorded port does not answer, stop that PID manually.
3. Run daemon status again. If the process is gone but .runtime/daemon.json is still present, remove the stale metadata file and start the daemon again.

Do not fix this by creating a second accidental workspace in the repo. The correct recovery target is the original workspace.

The Contract (TL;DR)

The hub owns structure. The LLM owns content.

• LLM writes — statuses, assignees, dependencies, notes, tags, priorities, new tasks, scratchpad
• Hub enforces — task array order, existence (no accidental deletion), human UI state (drag positions, swimlane collapse), version stamps

Two patch-time guardrails now matter for agent reliability:

• append brand-new patch tasks only as not_started or in_progress, not already complete or deferred
• use reference / references[] only in path:line or path:line-line form; bare URLs are rejected with an explicit hint

LLMs send small patches. The hub merges them under a per-project lock, bumps meta.rev, writes a full snapshot, and appends a {rev, delta} line to the history log. When the LLM needs to refresh, it calls GET /api/projects/:slug/since/<last-rev> and gets only what changed — constant-size payload regardless of project size.

For task pickup, prefer the atomic claim flow over hand-built status patches:

• GET /api/projects/:slug/tasks/:taskId/brief
• npx llm-tracker brief <slug> <task-id>
• GET /api/projects/:slug/tasks/:taskId/why
• npx llm-tracker why <slug> <task-id>
• GET /api/projects/:slug/decisions
• npx llm-tracker decisions <slug>
• GET /api/projects/:slug/tasks/:taskId/execute
• npx llm-tracker execute <slug> <task-id>
• GET /api/projects/:slug/tasks/:taskId/verify
• npx llm-tracker verify <slug> <task-id>
• POST /api/projects/:slug/pick
• npx llm-tracker pick <slug> [task-id] --assignee <model>

For feature-oriented or fuzzy questions, prefer:

• GET /api/projects/:slug/search?q=<query>
• npx llm-tracker search <slug> <query>
• GET /api/projects/:slug/fuzzy-search?q=<query>
• npx llm-tracker fuzzy-search <slug> <query>

Legacy compatibility: if an older patch or tracker file still uses status: "partial", the hub normalizes it to in_progress on ingest and writes back the canonical value.

outcome is separate from status: use partial_slice_landed when a bounded slice shipped but the task remains open. Progress % still keys only off the four status values above.

Semantic search stack

• Semantic /search uses @huggingface/transformers in the local Node.js hub.
• The default embedding model is Xenova/all-MiniLM-L6-v2.
• Both are Apache-2.0 licensed.
• The first semantic query may download the model into the local Hugging Face cache; after that, query embedding and cosine ranking stay local.
• Semantic /search now tries the native Node runtime first, then a local WASM runtime bundled from onnxruntime-web, then a bundled offline hash runtime, and only then degrades to deterministic fuzzy matching.
• If semantic has to fall back, the payload returns a warning. If model runtimes are unavailable, /search can still return semantic results with backend: "semantic_hash_fallback"; only unexpected runtime failures degrade to backend: "fuzzy_fallback".
• /fuzzy-search remains the deterministic lexical fallback when you want approximate string matching without loading embeddings.

Two write modes:

• Mode A — File patches (bash-less): LLM drops a JSON patch in patches/<slug>.<ts>.json; hub picks it up and deletes it.
• Mode B — HTTP patches (fastest): POST /api/projects/:slug/patch; one-time curl approval in your CLI, then no filesystem access.

Patch failures now return error, type, and hint so agents do not have to reverse-engineer raw schema regex output. The same hint-bearing payload is also written to .errors.json files in file-patch mode.

Full schema, merge semantics, field ownership, versioning, rollback, and the whole LLM-facing contract → ARCHITECTURE.md.

Migrating an older 0.1.x workspace or tracker set to the 1.0.0 contract, including agent backfill guidance for the new fields → MIGRATING.md.

That migration guide also covers existing shared-workspace projects linked from repo worktrees: relink the slug to the intended branch file, reload it, backfill bounded active tasks first, verify with execute / verify / search, and stop before any commit unless the human asked for one.

If a linked slug is already registered, the safe relink flow is: remove the current workspace symlink registration, re-link the slug to the new absolute target path, then reload it. That unregister step removes only the shared workspace symlink, not the real tracker file in the repo/worktree.

It now also calls out an easy failure mode: a patch that adds only references[], effort, related, and comment is retrieval-only enrichment, not a complete migration batch for active tasks.

The migration guidance now also tells agents to evaluate the full author-owned field set for active tasks, including goal, context.*, and blocker_reason, rather than treating only the retrieval and execution-contract subsets as the whole job.

It also now makes the reference rule explicit: for linked repo-local trackers, keep repo file references portable and repo-relative. If a valid repo-relative reference is not producing snippets, reload and treat it as a resolver/runtime problem to report, not as a cue to rewrite the tracker with machine-specific absolute paths.

Contributing & releases

The repo ships every change through issues → feature branch → PR → automated release.

1. Propose a change — open a GitHub issue (bug, enhancement, etc.). Attach it to a milestone if you want it scoped to a specific release.

2. Branch + PR — branch off main using a prefix that matches the work (fix/…, feat/…, docs/…, chore/…). main is protected: no direct pushes, PR-only, linear history, squash-merge.

3. PR title = Conventional Commits — squash-merge uses the PR title as the commit subject on main. A CI check rejects titles that don't match feat: / fix: / docs: / refactor: / perf: / chore: / etc. Close the relevant issue with Closes #N in the body.

4. Merge lands on main immediately — no need to hold PRs for a release. Feature work and releases are decoupled.

5. Release-please accumulates — every commit on main updates a rolling "release PR" (auto-opened by release-please) that bumps package.json and appends to CHANGELOG.md based on the commit types:

Commit type(s) since last tag	Version bump
any feat!: / BREAKING CHANGE: footer	major (x.0.0)
any feat:	minor (0.x.0)
only fix: / perf:	patch (0.0.x)
only chore: / ci: / test: / docs: / refactor:	no bump (hidden from notes)

6. Cut a release — merge the release PR when you want to ship. That tags v*.*.*, which triggers publish.yml → npm publish. You decide the cadence: after every feature, weekly, or whenever a milestone closes.

Workflow files: .github/workflows/release-please.yml, .github/workflows/pr-title.yml, release-please-config.json.

Local security

The hub is a local service. It ships three layers that matter if another process (or a browser tab on the same machine) tries to talk to it:

• Loopback binding — by default the listener binds to 127.0.0.1, so other hosts on the LAN cannot reach it. Override with LLM_TRACKER_HOST=0.0.0.0 if you consciously want LAN access.
• Cross-origin guard — every mutating request (POST / PUT / PATCH / DELETE) must either have no Origin header (trusted CLI / curl / MCP context) or carry an origin that exactly matches the hub origin serving that request. Loopback origins are always allowed too. Anything else returns 403, so browser CSRF stays blocked even if you deliberately expose the hub on a LAN IP.
• WebSocket guard — /ws uses the same origin policy. Cross-origin browser upgrades are rejected with 403, so a malicious page cannot subscribe to tracker broadcasts from another site.
• Optional bearer token — set LLM_TRACKER_TOKEN=<secret> before starting the hub and every mutating request must include Authorization: Bearer <secret> (or X-LLM-Tracker-Token: <secret>). The CLI picks the token up from the same env var automatically. The browser UI gets a short-lived HttpOnly same-origin session cookie when it loads index.html, so the raw secret is never injected into page JavaScript.
• WebSocket auth when tokenized — when LLM_TRACKER_TOKEN is set, /ws also requires Authorization: Bearer <secret> (or X-LLM-Tracker-Token) unless the request carries the UI's short-lived same-origin session cookie.

Body-size hardening:

• Default JSON body limit is 1 MB (override with LLM_TRACKER_BODY_LIMIT, e.g. LLM_TRACKER_BODY_LIMIT=4mb).
• Route-level guards reject oversized meta.scratchpad (> 5000 chars), task.comment (> 500 chars), and task.blocker_reason (> 2000 chars) before merge/validation runs, so hallucinated jumbo patches cost the hub almost nothing.

Deleted-project restore

DELETE /api/projects/<slug> (or the UI [DELETE] button) removes the registered tracker file but preserves .snapshots/<slug>/ and .history/<slug>.jsonl for audit. To bring a deleted project back:

# restore latest snapshot
llm-tracker restore <slug>

# restore a specific rev
llm-tracker restore <slug> --rev 7

Or over HTTP:

curl -X POST http://localhost:4400/api/projects/<slug>/restore \
  -H "Content-Type: application/json" -d '{"rev": 7}'

restore vs undo vs rollback:

• restore — bring back a project that was fully deleted (DELETE /api/projects/<slug>). Refuses if the project is still registered, writes a fresh audited rev, and records a restore event in .history/<slug>.jsonl.
• undo — reverse the last accepted revision on a currently registered project.
• rollback — set a registered project back to any prior rev as a new, auditable rev.

Tombstones — when a human deletes a task (via the UI [×] button or DELETE /api/projects/<slug>/tasks/<taskId>), the id is recorded in meta.deleted_tasks. This hub-owned list blocks stale LLM writes from silently resurrecting the deleted task. Rolling back to a rev that predates the deletion clears the tombstone.

Windows support

The hub runs on Windows, but a few paths need extra care:

• Symlinking repo-local trackers (llm-tracker link, Option C) — symlinkSync requires either Developer Mode (Settings → Privacy & security → For developers) or running the shell as Administrator. If you hit EPERM / EACCES, fall back to PUT /api/projects/<slug> (Option B) instead — it has no filesystem-privilege requirements.
• File watchers — the main trackers/ watcher uses native filesystem events. Polling is enabled only for symlinked targets that live outside the workspace, and only on the specific target files — not their parent directories — so CPU cost stays bounded even when a target lives deep inside a repo.
• Line endings — tracker JSON is written with \n on all platforms. Leave core.autocrlf to your preference in the repo itself; the hub never rewrites linked files for EOL.
• Paths — Windows absolute paths (C:\Users\...) work everywhere an absolute path is expected.
• LAN access — if you override LLM_TRACKER_HOST, open the UI through the real host or IP you bound for. Browser writes remain same-origin only; a page loaded from some other site still gets 403.

CI currently targets Linux and macOS. Windows-specific behavior is documented but not yet gated by CI — expect the Linux/macOS matrix to be the canonical coverage until a Windows runner lands.
