TORCH: Task Orchestration via Relay-Coordinated Handoff

TORCH is a decentralized task-locking protocol for multi-agent software development. This document serves as the primary manual for both human operators and AI agents working within a TORCH-enabled repository.

Agent Operating Guide

This section defines how agents should work in this repository.

Purpose

• Keep agent work predictable, auditable, and safe.
• Minimize repeated discovery work across sessions.
• Capture durable learnings so future agents can move faster.

Session startup checklist (run every session)

1. Read TORCH.md (this file).
2. Read CONTRIBUTING.md for commit and PR expectations.
3. Read KNOWN_ISSUES.md for active blockers and workarounds.
4. Read docs/agent-handoffs/README.md.
5. Scan recent notes in:
   • docs/agent-handoffs/learnings/
   • docs/agent-handoffs/incidents/
6. If present, review the current run artifacts in:
   • src/context/
   • src/todo/
   • src/decisions/
   • src/test_logs/
   • src/issues/

Core operating principles

• Default to generic guidance and neutral language.
• Make the smallest safe change that satisfies the request.
• Avoid unrelated refactors.
• Preserve backward compatibility unless explicitly asked otherwise.
• Prefer explicit commands and documented behavior over assumptions.
• Record assumptions clearly in your final summary.

Validation policy

• Run the most relevant checks for changed files (tests, lint, typecheck, build, or targeted scripts).
• Never claim a check passed unless it was actually executed.
• If a check cannot run, record:
  • command attempted,
  • why it could not complete,
  • what fallback validation was performed.

Execution Workflow

1. Load baseline context (see Session startup checklist above).
2. Clarify the task
   • Restate the requested outcome.
   • Identify constraints, risks, and assumptions.
3. Plan minimal changes
   • Keep scope tight.
   • Avoid touching unrelated files.
4. Implement
   • Apply small, reversible edits.
   • Favor readability and maintainability.
5. Validate
   • Run relevant checks for impacted files.
   • Capture exact commands and outcomes.
6. Document and hand off
   • Summarize what changed and why.
   • Record reusable learnings/incidents when appropriate.

Working files for session state

Use the following folders as lightweight coordination artifacts:

• src/context/ — Current objective, scope, constraints.
• src/todo/ — Task checklist and blockers.
• src/decisions/ — Important design/implementation choices.
• src/test_logs/ — Validation commands and results.
• src/issues/ — Investigations or audits that may become tracked issues.

Content templates

Context note: Goal, Scope, Constraints, Open questions. Todo note: Pending tasks, Completed tasks, Blocked tasks. Decision note: Decision, Alternatives considered, Rationale, Consequences/follow-ups. Test log: Command, Result (pass/fail/warn), Notes (environmental limits, retries, artifacts).

Knowledge-sharing protocol

What belongs where

• KNOWN_ISSUES.md: Active, reproducible issues only. Include status, impact, workaround, and last verification date.
• docs/agent-handoffs/learnings/: Proven patterns, repeatable fixes, and successful implementation guidance.
• docs/agent-handoffs/incidents/: Failures, root causes, mitigations, and prevention guidance.
• src/context/, src/todo/, etc.: Ephemeral session state.

Naming standard

Use: YYYY-MM-DD-short-topic.md (e.g., 2026-02-14-validation-before-summary.md). Keep names concise, descriptive, and neutral.

Required sections for reusable notes

1. Context
2. Observation
3. Action taken
4. Validation performed
5. Recommendation for next agents

Update decision tree

When you discover reusable context:

1. Check if an existing note already covers it.
2. If yes, update that note.
3. If no, add a new note in learnings/ or incidents/.
4. If the issue is still active/reproducible, add or update KNOWN_ISSUES.md.

Quality checklist before completion

• Scope matches request.
• Documentation remains repository-agnostic unless explicitly needed.
• No unsupported claims about testing.
• Assumptions and limitations are called out.
• Changes are easy to revert.

Anti-patterns to avoid

• Embedding product/company-specific guidance in baseline docs.
• Large refactors when a focused change is sufficient.
• Skipping validation without recording why.
• Creating duplicate notes when an update would suffice.

Dashboard & Protocol Overview

The TORCH dashboard subscribes to Nostr relays for kind 30078 events tagged with the #torch-agent-lock hashtag. These are the same events agents publish via bin/torch-lock.mjs when they claim tasks using the TORCH protocol.

Relays: wss://relay.damus.io, wss://nos.lol, wss://relay.primal.net

Filter: {"kinds":[30078],"#t":["torch-agent-lock"]}

Unique identifier: All events use the torch-lock/ namespace in the d-tag and the #torch-agent-lock hashtag. This scopes events to this repository and is how both agents and the dashboard filter messages.

To follow in any Nostr client, subscribe to kind 30078 with #t = torch-agent-lock on the relays above.

Quick start

# Check active locks
node bin/torch-lock.mjs check --cadence daily

# Machine-readable lock output (recommended for automation)
node bin/torch-lock.mjs check --cadence daily --json --quiet --json-file /tmp/torch-lock-check.json

# Claim a task
AGENT_PLATFORM=codex node bin/torch-lock.mjs lock --agent docs-agent --cadence daily

# List all active locks
node bin/torch-lock.mjs list

# Probe relay health before scheduler lock acquisition
node bin/torch-lock.mjs health --cadence daily

Defaults

• Kind: 30078 (NIP-33 parameterized replaceable)
• Expiration: NIP-40 via expiration tag
• TTL: 7200s (2h)
• Namespace: torch
• Relays:
  • wss://relay.damus.io

torch-config.json

You can configure TORCH per repository with a root-level torch-config.json file.

Common settings:

• nostrLock.namespace — namespace prefix used in d-tags and hashtags.
• nostrLock.relays — relay list for check/lock/list operations.
• nostrLock.ttlSeconds — default lock TTL.
• nostrLock.queryTimeoutMs — relay query timeout (ms, valid range: 100..120000).
• nostrLock.publishTimeoutMs — per-relay publish timeout (ms, valid range: 100..120000).
• nostrLock.minSuccessfulRelayPublishes — minimum successful publishes required before lock acquisition continues (default: 1).
• nostrLock.relayFallbacks — optional fallback relay URLs used when primary query/publish attempts fail quorum.
• nostrLock.minActiveRelayPool — minimum number of relays kept active even when lower-ranked relays are quarantined (default: 1).
• nostrLock.dailyRoster / nostrLock.weeklyRoster — optional per-project roster overrides.
• dashboard.defaultCadenceView — default dashboard view (daily, weekly, all).
• dashboard.defaultStatusView — default dashboard status filter (active, all).
• dashboard.hashtag — custom hashtag for lock events (defaults to <namespace>-agent-lock).
• scheduler.firstPromptByCadence.daily / .weekly — first-run scheduler starting agent.
• scheduler.handoffCommandByCadence.daily / .weekly — shell command run after lock acquisition; command must use SCHEDULER_AGENT, SCHEDULER_CADENCE, and SCHEDULER_PROMPT_PATH provided by scripts/agent/run-scheduler-cycle.mjs.
• scheduler.paused.daily / .weekly — array of agent names to exclude from scheduler rotation.
• scheduler.strict_lock — lock backend policy switch (default: true); when false, scheduler defers backend-unavailable lock failures before converting the run to failed.
• scheduler.degraded_lock_retry_window — non-strict deferral window in milliseconds; backend lock failures outside this window immediately consume failure budget and mark run failed.
• scheduler.max_deferrals — max number of non-strict lock deferrals allowed in-window before scheduler records a hard failure.

Default first-run daily scheduler prompt is scheduler-update-agent.

For weekly repository-fit maintenance, TORCH also includes src/prompts/weekly/repo-fit-agent.md to periodically adjust defaults and docs to the host repository.

Operational note: scheduler handoff commands are treated as required execution steps. A non-zero exit code (or missing command) is a hard failure: the scheduler writes a _failed.md task log, exits immediately, and does not publish lock:complete for that run.

Scheduler failure classes in task logs:

• backend_unavailable — legacy compatibility field for lock backend unavailable failures.
• prompt_validation_error — legacy compatibility field for prompt/runtime validation failures.

Scheduler failure categories in task logs:

• lock_backend_error — lock backend unavailable preflight failures and lock acquisition backend exit code 2 failures/deferrals; includes relay health alert metadata, retry window guidance, health check command, and incident runbook link.
• prompt_parse_error — scheduler could not read/parse the selected prompt file; prompt execution is skipped.
• prompt_schema_error — selected prompt file or generated run artifacts failed schema/contract checks; prompt run is treated as invalid.
• execution_error — runtime execution failures in handoff callbacks, memory commands, or configured validation commands.

Lock backend production defaults

Recommended baseline for production scheduler runs:

• nostrLock.relays: 3+ geographically-diverse primary relays.
• nostrLock.relayFallbacks: 2 additional relays not present in primary list.
• nostrLock.queryTimeoutMs: 10000
• nostrLock.publishTimeoutMs: 8000
• nostrLock.minSuccessfulRelayPublishes: 2
• nostrLock.minActiveRelayPool: 2

Validation behavior:

• Relay URLs must be absolute ws:// or wss:// URLs.
• Invalid relay URLs or invalid timeout/count ranges are fatal startup errors.
• Lock backend errors include phase (query:primary, query:fallback, publish:primary, publish:fallback), relay endpoint, and timeout value used.
• When scheduler preflight fails before lock acquisition, task logs must explicitly state prompt not executed to make lock-vs-prompt root cause obvious in UI/CLI summaries.
• Interpret relay_publish_quorum_failure (derived from lock_publish_quorum_failed telemetry) as quorum not met even after retries/fallbacks. Expected operator actions:
  1. Run npm run lock:health -- --cadence <daily|weekly> to confirm relay readiness and identify failing relays/reasons.
  2. Review task log metadata (lock_failure_reason_distribution, backend_category, lock_correlation_id) for dominant failure modes (timeouts, DNS, auth, malformed relay URL).
  3. If failures persist past retry window, follow incident runbook docs/agent-handoffs/learnings/2026-02-15-relay-health-preflight-job.md and escalate relay/network remediation.
• Relay health snapshots are emitted periodically and whenever lock publish/query fails; snapshots include success rate, timeout rate, rolling latency, and quarantine state per relay.

Scheduler lock reliability reporting

Run the lock reliability summary to aggregate recent scheduler outcomes by platform, cadence, backend error category, and relay endpoint:

npm run report:lock-reliability

Outputs:

• artifacts/lock-reliability/lock-reliability-summary.md
• artifacts/lock-reliability/lock-reliability-summary.json

Roster precedence

The lock CLI resolves roster names in this order:

1. NOSTR_LOCK_DAILY_ROSTER / NOSTR_LOCK_WEEKLY_ROSTER (comma-separated env overrides).
2. torch-config.json (nostrLock.dailyRoster / nostrLock.weeklyRoster).
3. src/prompts/roster.json (daily / weekly canonical scheduler roster).
4. Built-in fallback roster (used only if src/prompts/roster.json is unreadable).

lock --agent validates names against the resolved cadence roster, and check/list report lock events whose agent names do not match scheduler roster entries exactly.

Exit codes

• 0: success
• 1: usage error
• 2: relay/network error
• 3: lock denied (already locked or race lost)

Memory rollout plan

1. Deploy memory schema changes with scheduler jobs disabled (TORCH_MEMORY_ENABLED=false or subsystem flags set to false).
2. Enable ingest for one canary agent_id via TORCH_MEMORY_INGEST_ENABLED=<agent_id>.
3. Validate retrieval quality and storage growth metrics before expanding scope.
4. Enable broader retrieval (TORCH_MEMORY_RETRIEVAL_ENABLED=<allow-list> then true).
5. Enable pruning in dry-run mode first, then switch to active pruning after revalidation.

Memory rollback plan

1. Disable memory flags (TORCH_MEMORY_ENABLED=false and/or set ingest/retrieval/prune flags to false).
2. Stop memory maintenance scheduler processes.
3. Preserve database state for post-incident analysis; do not drop or rewrite memory tables during rollback.
4. Keep prune actions in dry-run (or disabled) until lifecycle policy and data integrity are revalidated.

Offline & Air-Gapped Installation

TORCH is designed to operate in diverse environments, including high-security, air-gapped, or offline networks where direct access to the npm registry is restricted.

The Offline Bundle

The "Offline Bundle" is a standard npm package tarball (.tgz) generated during the build process. It contains the complete source code and dependency definitions required to run TORCH.

Why use the bundle?

1. Security & Integrity: You can verify the checksum of the tarball before installing it. It creates a frozen snapshot of the code that doesn't change.
2. No Registry Dependency: You can install it directly using npm install ./torch-lock-0.1.0.tgz without needing to connect to registry.npmjs.org.
3. Project Integration: Unlike a binary executable, the tarball installs TORCH as a standard dependency in your package.json. This ensures:
   • Scripts like npm run lock:check work natively.
   • TORCH versioning is managed alongside your other dependencies.
   • It works across all operating systems that support Node.js.

Installation Instructions

1. Download the tarball from the landing page or your internal artifact repository.

2. Place it in your project root or a vendor/ directory.

3. Run the install command:

   npm install ./torch-lock-0.1.0.tgz
   

   (Replace 0.1.0 with the actual version number)

4. Initialize TORCH:

   npx torch-lock init
