providing life-assistant functionality to a single user via Telegram. Built on Anthropic's Claude API + (Sonnet as orchestrator, Haiku as collectors), the system integrates home automation (Home Assistant), + health metrics (Apple Health via custom receiver), browser history (PostgreSQL), location tracking + (OwnTracks/MQTT), email (Gmail via GOG), and YouTube activity into a 30-minute heartbeat cycle. + Key architectural decisions include a two-tier memory system (KNOWLEDGE.md for stable cached context, + MEMORY.md for volatile in-progress state), a parallel subagent heartbeat architecture replacing an + earlier sequential 18-step approach, and deterministic script-based data collection replacing + unreliable LLM-based collectors. The system has been in continuous operation since February 2026, + with ongoing evolution documented in HISTORY.md. This ARA captures the system design, key + architectural decisions, documented dead ends, and operational heuristics as a structured + machine-readable artifact. +--- + +# Nanobot: A Persistent Life-Assistant Agent System Built on Claude + +## Overview + +Nanobot is a self-hosted, single-user life-assistant AI agent that runs persistently on a home Unraid server +and communicates with its user (Makar Novozhilov, Barcelona) exclusively via Telegram. Unlike stateless +chatbot deployments, nanobot maintains persistent session state, runs an autonomous 30-minute heartbeat +cycle for life tracking, and orchestrates parallel subagents for data collection. + +The system is built on the nanobot open-source framework (originally from HKUDS Lab, MIT license, +February 2026), extended with custom skills, heartbeat logic, and infrastructure integrations. +Its primary intelligence layer is Anthropic Claude (Sonnet for orchestration, Haiku for lightweight +collection tasks). Prompt caching is central to cost control: KNOWLEDGE.md (stable facts, ~4KB) is +permanently cached in the system prompt, while MEMORY.md (volatile state) is excluded to prevent +cache invalidation on every session update. + +The heartbeat architecture evolved from a sequential 18-step monolithic Sonnet execution to a +parallel 8-Haiku-collector + Sonnet-orchestrator design, with data collectors eventually replaced by +deterministic bash/Python scripts to eliminate LLM hallucination of sensor data. Several infrastructure +dead ends are documented: Traefik TLS failures due to DNS bootstrap issues, Docker networking latency +from an unreachable Technitium nameserver, Yandex Station control failures from TTS/Alice confusion, +and SS14 CI/CD cache corruption from runner configuration errors. + +## Layer Index + +### Cognitive Layer (`/logic`) + +| File | Description | +|------|-------------| +| [problem.md](logic/problem.md) | Observations → gaps → key insights about persistent agent systems | +| [claims.md](logic/claims.md) | 9 falsifiable claims (C01–C09) about system architecture and design | +| [concepts.md](logic/concepts.md) | 8 key technical concepts with formal definitions | +| [experiments.md](logic/experiments.md) | 5 experiment plans (E01–E05) for validating architectural claims | +| [solution/architecture.md](logic/solution/architecture.md) | Full system component graph with inputs/outputs | +| [solution/algorithm.md](logic/solution/algorithm.md) | Heartbeat orchestration algorithm and subagent parallelism | +| [solution/constraints.md](logic/solution/constraints.md) | Boundary conditions, known limitations | +| [solution/heuristics.md](logic/solution/heuristics.md) | 11 operational heuristics (H01–H11) | +| [related_work.md](logic/related_work.md) | Related frameworks and projects (RW01–RW06) | + +### Physical Layer (`/src`) + +| File | Description | Claims | +|------|-------------|--------| +| [configs/infrastructure.md](src/configs/infrastructure.md) | Docker, Traefik, DNS, and service configs | C05, C06 | +| [configs/agent.md](src/configs/agent.md) | Agent model selection, caching, and heartbeat parameters | C01, C02, C03 | +| [execution/heartbeat_orchestrator.py](src/execution/heartbeat_orchestrator.py) | Heartbeat orchestrator stub | C01, C04 | +| [execution/collector_scripts.py](src/execution/collector_scripts.py) | Deterministic collector script pattern | C03 | +| [environment.md](src/environment.md) | Python version, dependencies, hardware, deployment | + +### Exploration Graph (`/trace`) + +| File | Description | +|------|-------------| +| [exploration_tree.yaml](trace/exploration_tree.yaml) | 18-node research DAG covering key architectural decisions and dead ends | + +### Evidence (`/evidence`) + +| File | Description | +|------|-------------| +| [README.md](evidence/README.md) | Full index of 6 tables + 2 figures | +| [tables/table1_heartbeat_architecture_evolution.md](evidence/tables/table1_heartbeat_architecture_evolution.md) | Evolution of heartbeat architecture from sequential to parallel | +| [tables/table2_dns_latency_incident.md](evidence/tables/table2_dns_latency_incident.md) | DNS latency dead end — Technitium unreachable from Docker | +| [tables/table3_yandex_failures.md](evidence/tables/table3_yandex_failures.md) | Yandex Station control attempts and failures | +| [tables/table4_memory_split.md](evidence/tables/table4_memory_split.md) | KNOWLEDGE.md vs MEMORY.md cache efficiency data | +| [tables/table5_ss14_cicd_dead_ends.md](evidence/tables/table5_ss14_cicd_dead_ends.md) | SS14 CI/CD debugging failures and cache corruption | +| [tables/table6_traefik_cert_failure.md](evidence/tables/table6_traefik_cert_failure.md) | Traefik TLS certificate failure due to DNS bootstrap | +| [figures/figure1_heartbeat_timeline.md](evidence/figures/figure1_heartbeat_timeline.md) | Heartbeat system timeline from launch to parallel architecture | +| [figures/figure2_memory_hierarchy.md](evidence/figures/figure2_memory_hierarchy.md) | Memory hierarchy: KNOWLEDGE.md / MEMORY.md / HISTORY.md | diff --git a/nanobot/evidence/README.md b/nanobot/evidence/README.md new file mode 100644 index 0000000..2459aa4 --- /dev/null +++ b/nanobot/evidence/README.md @@ -0,0 +1,23 @@ +# Evidence Index + +This directory contains all raw evidence tables and figures supporting the claims in `logic/claims.md`.

The conversational agent operates in the `telegram:239824268` session; the heartbeat operates in a `cli:direct` or `heartbeat` session. These sessions share no in-memory state. The message() tool is the only mechanism by which the heartbeat session can inject content into the Telegram session's visible context. +- **Boundary conditions**: Session files grow without bound; the `hb-context` collector uses `tail -n 200` to avoid context exhaustion.

But the orchestrator is likely hallucinating the YouTube data during 'recovery' instead of properly calling the API" +- **Implication**: LLM-based data collection is fundamentally unreliable; deterministic scripts must replace LLM collectors for sensor data. + +### O4: Docker DNS resolution failures cause cascading infrastructure failures +- **Statement**: The Unraid Docker daemon had Technitium DNS (192.168.1.50) listed first in container resolv.conf, but Technitium was unreachable via Docker NAT, causing 8-second DNS latency on all outbound requests. +- **Evidence**: HISTORY.md [2026-02-13]: "Discovered 8-second DNS latency in all Docker containers caused by 192.168.1.50 (Technitium, unreachable via Docker NAT) and 169.254.24.117 (dead Docker embedded DNS) before working 1.1.1.1... Container had to be restarted externally." Fix: "set {'dns': ['172.17.0.1']} in /etc/docker/daemon.json on Unraid, persisted in /boot/config/go. Technitium runs in host mode so it binds to docker0 bridge gateway — containers now resolve in ~2ms." +- **Implication**: Infrastructure-level DNS configuration is a hard dependency for any skill/tool that makes outbound network calls. + +### O5: Heartbeat subagents running in a separate session create split-identity context gaps +- **Statement**: The heartbeat runs in a "heartbeat" session distinct from the "telegram:239824268" session. Messages sent by the heartbeat via Telegram are not visible to the conversational agent when the user replies. +- **Evidence**: HISTORY.md [2026-02-21]: "Design flaw: heartbeat sends Telegram messages via separate CLI invocation, those messages don't appear in the conversation agent's session context. Same bot identity from user's perspective but no shared context." +- **Implication**: All outbound messages from heartbeat subagents must be relayed through the main agent's message() tool, or written into the main session file, to preserve context continuity. + +### O6: Sequential heartbeat processing creates iteration budget exhaustion +- **Statement**: The original 18-step sequential heartbeat design caused subagents to run out of iterations (max_iterations=15) before completing all steps, causing silent failures. +- **Evidence**: HISTORY.md [2026-02-14 10:21]: "Debugged heartbeat subagent failure — subagents were running out of iterations (max_iterations=15) before completing all 15 heartbeat steps. User chose to increase limit to 50 instead of consolidating into a bash script." +- **Implication**: Sequential LLM orchestration does not scale to many-step workflows; parallel architecture with bounded per-task iteration counts is necessary. + +### O7: Traefik TLS certificate issuance fails due to DNS bootstrap dependency +- **Statement**: Traefik's ACME DNS-01 challenge requires resolving the domain's DNS records, but when Traefik itself is the reverse proxy for the DNS service and the DNS service is not yet reachable, the certificate challenge cannot be completed. +- **Evidence**: HISTORY.md [2026-12-14]: "SS14 server (wylab-station-14) CI/CD pipeline not triggering on commits.

The discovery that MEMORY.md updates busted the cache on every turn was the direct cause of the architectural split. + - Why: Without the cache split, each MEMORY.md write would invalidate the system prompt cache, causing 10-16k tokens to be re-processed at full write cost on every session turn.

Multi-user support would require session isolation, per-user life_state.json, and per-user KNOWLEDGE.md. + +### IC02: Network topology dependency +All home automation features (vacuum, Yandex Station, health receiver) require the nanobot container to be on the same LAN as the Unraid server (192.168.1.50). Remote operation (e.g., from a VPS) would require VPN tunneling or HA Cloud. + +### IC03: Anthropic API exclusivity +The system uses Anthropic's OAuth token (Claude Max subscription) as the sole LLM provider. There is no fallback to local models (Ollama was set up separately but not integrated into the main agent flow). Rate limits and quota exhaustion cause heartbeat failures. + +### IC04: Container restart resets ephemeral state +Several dependencies are ephemeral in the container: Playwright dependencies (must reinstall), some pip packages. All persistent state lives in Docker volume mounts: `/root/.nanobot/workspace/` and `/root/.config/`. + +### IC05: Yandex Station Quasar API dependency +Yandex Station control works via the Quasar cloud API accessed through Home Assistant, not via local network. If Yandex's cloud is unavailable, station control fails silently. + +--- + +## Behavioral Constraints + +### BC01: Never write to /etc/resolv.conf from within the container +Established after self-inflicted DNS outage on 2026-02-13. Writing to resolv.conf and leaving only broken nameservers caused a container that had to be restarted externally. Rule: never write system config files inside the container. + +### BC02: Vacuum maximum once per day, never while home +The Lefant M2 vacuum is started only when: (a) Makar is >200m from home coordinates (41.384588, 2.136307), and (b) `life_state.last_vacuum_run` is not already today. This prevents the vacuum from running while Makar is home and prevents multiple daily runs. + +### BC03: Email alert deduplication via alerted_email_ids +Once an email thread ID is in `alerted_email_ids`, it must never trigger another alert, even if it appears in future heartbeat cycles. The set is append-only and persisted in `life_state.json`. + +### BC04: No code unless explicitly asked +Per KNOWLEDGE.md behavioral rules: "No code unless specifically asked — prefer existing solutions/auto-install scripts." Code blocks in responses are only appropriate when the user explicitly requests code. + +### BC05: Execute-first, narrate-second +Per KNOWLEDGE.md hard rules: "Do not say 'I will read X' or 'let me check Y'.

When the file exceeds ~200k tokens, even `tail -n 200` produces content that fills Haiku's context budget. No mitigation is currently deployed; the collector silently uses stale cache data when this occurs. + +### KL02: Sleep inference is unreliable during periods of autonomous activity +Yandex Station track changes (from music autoplay) are recorded as activity signals, incorrectly preventing sleep inference even when Makar is actually asleep. The current heuristic requires corroborating signals (no Telegram + home + stationary + late hours) but Alice's autoplay can mask sleep onset. + +### KL03: YouTube sync script 60-second timeout +The `youtube_sync.py` script has a hard 60-second timeout in the heartbeat execution model. When the YouTube API is slow or the Qdrant/mem0 write is blocked, the script times out and writes an error. This happens intermittently and has no automatic recovery. + +### KL04: P2P trading books have manual FX rate dependencies +The `build_books.py` double-entry bookkeeping system uses manually entered FX rates from the CBR (Russian Central Bank) for period-end FX retranslation. These rates cannot be automatically fetched (bankffin.kz requires JavaScript rendering; no public API). Freedom Finance rates require Playwright to scrape. + +### KL05: mem0 memory extraction can capture system architecture as user facts +When conversations discuss nanobot's infrastructure, mem0's extraction LLM may store these as user facts rather than system documentation, polluting the memory store with stale operational details. + +### KL06: Obsidian REST API uses plain HTTP +The Obsidian local REST API runs only on HTTP (port 27123), not HTTPS.

Any response under three words is almost certainly a filler acknowledgment rather than a real answer. +- **Sensitivity**: high +- **Bounds**: The rule applies to the final outbound message only.

Haiku is used for collectors (cheap, fast, sufficient for structured JSON extraction from API responses) while Sonnet handles orchestration and interpretation (requires reasoning about combined signals). The split reflects cost efficiency: interpretation is done once; collection is done eight times per cycle. +- **Sensitivity**: medium +- **Bounds**: Collector budgets must be respected to avoid orchestrator context overflow (~3,100 total chars / ~800 tokens across all 8 files). If a collector exceeds its budget, it must truncate — the orchestrator does not re-fetch. Changing from 8 to more collectors would require verifying the combined budget stays under Sonnet's usable context. +- **Code ref**: [`src/execution/heartbeat.py`](../../src/execution/heartbeat.py) +- **Source**: KNOWLEDGE.md §Heartbeat Architecture; HISTORY.md [2026-02-18 21:39] + +--- + +## H05: Dead end — Yandex Station TTS/Alice mode for playback control +- **Rationale**: Home Assistant exposes three mechanisms to interact with Yandex Station: TTS (text-to-speech, reads text aloud), Alice command passthrough, and direct `media_player/*` service calls. The first two feel semantically appropriate ("tell Alice to pause") but are functionally wrong — they cause the station to verbalize the instruction rather than execute it. The iron law in the yandex-station skill exists because this mistake was repeated 4-5 times in a single session before the correct API path was found. +- **Sensitivity**: high +- **Bounds**: NEVER use `tts.speak` or Alice command mode for playback control (pause, stop, volume, play). ALWAYS use `media_player/media_pause`, `media_player/media_stop`, `media_player/volume_set`, `media_player/play_media` directly. The TTS endpoint is only for synthesizing speech to the room speaker. +- **Code ref**: [`src/execution/heartbeat.py`](../../src/execution/heartbeat.py) +- **Source**: HISTORY.md [2026-02-14 03:05]; skills/yandex-station/SKILL.md + +--- + +## H06: Dead end — Writing to /etc/resolv.conf inside container +- **Rationale**: During the DNS latency investigation, the agent edited `/etc/resolv.conf` inside the running nanobot container to test nameserver configurations. Leaving only the broken nameserver in the file killed all DNS resolution, requiring an external container restart. This was a self-inflicted outage from confusing the investigation target (the broken DNS config) with the investigation tool (the container's own DNS client). +- **Sensitivity**: high +- **Bounds**: Never write to `/etc/resolv.conf` or other system config files (`/etc/hosts`, `/etc/docker/daemon.json`) from within the nanobot container. DNS configuration changes must be made on the Unraid host and applied via Docker daemon restart. The container's networking state is ephemeral and externally managed. +- **Code ref**: [`src/configs/model.md`](../../src/configs/model.md) +- **Source**: HISTORY.md [2026-02-13 18:16]; BC01 in constraints.md + +--- + +## H07: Dead end — SS14 CI/CD cache corruption from mixed-architecture runners +- **Rationale**: The SS14 project's CI/CD pipeline suffered repeated failures traced to `.NET` build cache corruption when an ARM64 macOS runner (OrbStack) shared cached binaries with an x64 external runner. The mixed-architecture cache caused incorrect binary reuse, cryptic build errors, and timeouts rather than clean failures. The fix (local per-runner file cache, no sharing) was only found after exhausting runner DNS fixes, host network mode, and shutdown timeout adjustments. +- **Sensitivity**: medium +- **Bounds**: Cross-architecture cache sharing must be disabled for compiled language build caches (`.NET`, Go, Rust). Separate cache keys per OS/architecture are required. Gitea cache ETIMEDOUT errors to a remote cache server (45.137.68.83:39913) are not the root cause — the underlying issue is cache key collision between architectures. +- **Code ref**: [`src/configs/model.md`](../../src/configs/model.md) +- **Source**: HISTORY.md [2026-12-14], [2026-12-15], [2026-12-18], [2026-12-19] + +--- + +## H08: Memory layout — KNOWLEDGE.md (stable) vs MEMORY.md (volatile) vs HISTORY.md (log) +- **Rationale**: Three distinct files serve three distinct roles. KNOWLEDGE.md is the permanent context: facts true across all sessions (identity, infrastructure, behavioral rules), loaded into the cached system prompt. MEMORY.md is the scratchpad: volatile state for the current project or deferred decisions, NOT in system prompt, read on demand. HISTORY.md is the archive: append-only event log, never edited, grep-searchable. The routing rule is deterministic: if a fact contains "currently", "recently", "planning to", or names an ongoing task, it belongs in MEMORY.md, not KNOWLEDGE.md. +- **Sensitivity**: medium +- **Bounds**: KNOWLEDGE.md must stay under ~8KB to maintain efficient cache write costs. MEMORY.md entries older than 30 days without references should be demoted to HISTORY.md before deletion. HISTORY.md entries are never edited retroactively — corrections are appended as new entries. +- **Code ref**: [`src/configs/training.md`](../../src/configs/training.md) +- **Source**: KNOWLEDGE.md §Memory Layout; HISTORY.md [2026-02-19 03:06] + +--- + +## H09: Deterministic scripts replace LLM collectors for factual data +- **Rationale**: LLM collectors (Haiku agents making API calls and summarizing results) can hallucinate: when the YouTube collector failed due to DNS, the Sonnet orchestrator "recovered" by generating plausible-looking video IDs and titles that did not exist on YouTube. This was discovered only when Makar noticed video IDs returning 404. The fix replaces LLM data collectors with deterministic Python/bash scripts that write exact API responses to JSON files, leaving LLM reasoning only for the interpretation step. +- **Sensitivity**: high +- **Bounds**: Any data source where correctness is ground truth (sensor readings, API responses, database queries) must use deterministic scripts. LLMs are appropriate only for the interpretation layer (understanding what the data means, deciding what actions to take). The hb-youtube collector was the first replacement; all 8 collectors are eventual targets. +- **Code ref**: [`src/execution/heartbeat.py`](../../src/execution/heartbeat.py) +- **Source**: HISTORY.md [2026-03-03 02:48], [2026-03-03 03:21] + +--- + +## H10: All subagent-to-user messages relay through main agent's message() tool +- **Rationale**: The heartbeat session and the conversational Telegram session are isolated — they share no in-memory state. When the heartbeat subagent sends a Telegram message via curl directly, the conversational agent has no record of what was sent. When the user replies, the conversational agent cannot see what triggered the reply, producing confused and inconsistent responses. The message() tool writes to both the Telegram API and the session JSONL file, making heartbeat-sent content visible to subsequent conversational turns. +- **Sensitivity**: high +- **Bounds**: This constraint applies to any subagent that communicates with the end user via a shared channel. If a subagent context only needs to communicate back to the main agent (not the user), it can use the subagent return result mechanism. If it needs to alert the user, it must use message() exclusively. +- **Code ref**: [`src/execution/heartbeat.py`](../../src/execution/heartbeat.py) +- **Source**: MEMORY.md [2026-05-01]; HISTORY.md [2026-02-21]; C04 in claims.md + +--- + +## H11: Email deduplication via append-only alerted_email_ids +- **Rationale**: The heartbeat checks email on every 30-minute cycle. Without deduplication, a single urgent email would generate an alert on every cycle until read. The `last_email_ids` field (which threads were last seen) is insufficient — a thread can be "seen" but re-appear if the seen list is not persisted or if the thread re-activates. `alerted_email_ids` is a separate, append-only set of thread IDs that have already produced an alert. Once a thread ID is in this set, it never fires again regardless of read status. +- **Sensitivity**: high +- **Bounds**: `alerted_email_ids` must never have entries removed — it is a one-way gate. The first 24 email thread IDs were pre-populated to prevent re-alerting existing backlog on initial deployment. New deployments should pre-populate from the current inbox to avoid a burst of stale alerts. +- **Code ref**: [`src/execution/heartbeat.py`](../../src/execution/heartbeat.py) +- **Source**: MEMORY.md [2026-05-01]; HISTORY.md [2026-03-23]; C09 in claims.md diff --git a/nanobot/src/.DS_Store b/nanobot/src/.DS_Store new file mode 100755 index 0000000000000000000000000000000000000000..e5785cfe38737d0a788f0a3a7245aa0011e68ff9 GIT binary patch literal 6148 zcmeHKK~BR!4D_~@NQIDklS2jt2DH7y0HX)2Y99`^}c`2+vp1)TW=4`94@ zOQQtT69QyQ-r0EVU1t)-F%h}ZW;!Gq5K#hU?DR3T2(Pm?q@xyIba9V6n$vnQALd2X z@HWG5WPqRD2^Cb)l5XhW`IRe4cXrkED61@+EUF1slJ~RAeEj-y(dIQh!fSQQZ_Dnq zfNiKxGulE6+R#06LT>U-?YthI+r19+dVA__HLsTa%IY(>?>+1JJ#u~~#(*(k4E%Kl zP_tQ*Q$ZVz0b{@z*fYT22M=XT6@y^>bYO@r0I&yh6wJAo;25u%Dh5HUK%9gECDdt) z;UpY(uYRdw5R`Co+I%=Y*=dL3;_2AmM|X0mppC|WF;HiqE0+VV|KqRw|9X&J83V?^ zzhc1kvOF8%mbA7uZjNiMhh9Tj*e?j~LokV@7`|MJ&!JIZ_dEfnia`(-i2Vpe8f-8I Hew2X^@%L0I literal 0 HcmV?d00001 diff --git a/nanobot/src/configs/agent.md b/nanobot/src/configs/agent.md new file mode 100644 index 0000000..58477fd --- /dev/null +++ b/nanobot/src/configs/agent.md @@ -0,0 +1,99 @@ +# Agent Configuration + +## Model Selection + +### main_agent_model +- **Value**: `claude-sonnet-4-6` (or current Sonnet release) +- **Rationale**: Used for the main conversational agent.

The central problem was a circular dependency: Traefik needed DNS to resolve Let's Encrypt ACME endpoints, but the DNS server (Technitium) was itself a Docker container exposed through Traefik. Secondary problems included 8-second DNS latency from containers caused by unreachable nameservers in resolv.conf, and a complementary issue where containers running in host network mode could not use the docker0 bridge gateway IP. Solutions required explicit DNS configuration in daemon.json, iptables DNAT rules, and startup script persistence in /boot/config/go. Several plausible-looking approaches (adding 1.1.1.1 to container DNS, host networking for all containers, editing resolv.conf directly) either failed or caused new problems." +--- + +# Traefik + Technitium DNS + Docker Networking on Unraid + +## Overview + +The wylab.me home server runs Traefik v2 as a reverse proxy in front of 20+ Docker containers on an Unraid server (UM790 Pro, 32GB RAM). Technitium DNS runs as a Docker container in host network mode, handling internal DNS for the wylab.me domain. + +The infrastructure accumulated two interlocking problems: + +1. **DNS latency**: All bridge-networked Docker containers experienced ~8-second latency on every DNS query. Root cause: `/etc/resolv.conf` listed `192.168.1.50` (Technitium's LAN IP) first, but UDP responses from that IP were dropped by Docker's NAT/conntrack layer for bridge-networked containers. + +2. **ACME circular dependency**: Traefik could not obtain Let's Encrypt TLS certificates because it resolved ACME endpoints through Technitium DNS. If Technitium was unavailable or misconfigured, Traefik's certificate renewal would fail — and Technitium's own management UI (dns.wylab.me) was itself served by Traefik, creating a chicken-and-egg loop. + +The solutions were: (a) set Docker daemon DNS to `172.17.0.1` (the docker0 bridge gateway, where Technitium listens in host mode), (b) add iptables DNAT rules for host-networked containers, and (c) persist both in `/boot/config/go`.

UDP DNS queries from bridge-networked containers to `172.17.0.1:53` succeed and return in ~2ms. Queries to `192.168.1.50:53` (the host LAN IP) are dropped by the Docker NAT/conntrack layer and never receive a UDP response from inside bridge containers. +- **Status**: supported +- **Falsification criteria**: A bridge container successfully receives a UDP DNS response from `192.168.1.50` in under 100ms, or `172.17.0.1` DNS queries fail from a standard bridge container. +- **Proof**: [E01] +- **Evidence basis**: After setting Docker daemon DNS to `172.17.0.1` in `/etc/docker/daemon.json`, all bridge containers resolved DNS in ~2ms (down from ~8s). Prior to the fix, `192.168.1.50` was listed in resolv.conf but DNS queries consistently timed out waiting for its response. +- **Interpretation**: The Docker NAT layer intercepts packets from bridge containers destined for the host's LAN IP. Only the docker0 gateway IP (`172.17.0.1`) is addressable by bridge containers for host-networked services. +- **Dependencies**: none +- **Tags**: docker, networking, technitium, bridge-network, dns, 172.17.0.1 + +--- + +## C02: Setting Docker daemon DNS to 172.17.0.1 eliminates 8-second DNS latency for all bridge-networked containers +- **Statement**: Adding `{"dns": ["172.17.0.1"]}` to `/etc/docker/daemon.json` causes all newly created bridge-networked containers to use `172.17.0.1` as their sole DNS server, reducing DNS resolution latency from ~8 seconds to ~2ms for all containers without any per-container configuration. +- **Status**: supported +- **Falsification criteria**: DNS latency remains above 1 second after the daemon.json change and Docker daemon restart, or individual containers require per-container DNS override to achieve fast resolution. +- **Proof**: [E01, E02] +- **Evidence basis**: Root-access Claude applied `{"dns": ["172.17.0.1"]}` to daemon.json in the 2026-02-13 fix session. Post-fix observation confirmed ~2ms DNS resolution. All 20+ containers were fixed by this single change. +- **Interpretation**: This is a system-wide fix that eliminates the latency for all containers, including future ones, without any per-container configuration. The fix propagates to all containers by being set at the daemon level. +- **Dependencies**: C01 +- **Tags**: docker, dns-latency, daemon.json, system-wide + +--- + +## C03: The ACME circular dependency is broken by configuring Traefik with an explicit public DNS server (e.g., 1.1.1.1) for certificate operations +- **Statement**: Traefik's ACME resolver can be configured with an explicit DNS server IP (`resolvers = ["1.1.1.1:53"]` in the certificatesResolvers section) so that Let's Encrypt endpoint resolution (`acme-v02.api.letsencrypt.org`) bypasses Technitium entirely. This eliminates the circular dependency where Traefik would need a healthy Technitium to renew certificates that keep Technitium's UI accessible. +- **Status**: supported +- **Falsification criteria**: Traefik successfully renews certificates even without the explicit resolver field set, or the explicit resolver field has no effect on which DNS server Traefik uses for ACME operations. +- **Proof**: [E03] +- **Evidence basis**: Browser history shows ACME research on 2026-03-07, followed by checking dns.wylab.me (Technitium admin). The PAPER.md abstract identifies this as a resolved problem. The traefik config template includes the resolver override. +- **Interpretation**: The `resolvers` field in Traefik's certificatesResolvers configuration is the minimal intervention point. It affects only ACME DNS lookups, not general Traefik DNS behavior, making it a surgical fix that doesn't change how Traefik routes other traffic. +- **Dependencies**: none +- **Tags**: traefik, acme, letsencrypt, circular-dependency, dns, certificates + +--- + +## C04: Startup script persistence in /boot/config/go makes daemon and iptables configuration survive Unraid reboots +- **Statement**: Writing Docker daemon DNS configuration commands and iptables DNAT rules to `/boot/config/go` causes those settings to be applied on every Unraid boot, making the DNS fix and network routing rules permanent across reboots. Without this persistence, all runtime configuration is lost when Unraid reboots from its flash drive. +- **Status**: supported +- **Falsification criteria**: The daemon.json change or iptables rules persist across a full Unraid power cycle without entries in `/boot/config/go`, or `/boot/config/go` entries fail to execute on boot. +- **Proof**: [E04] +- **Evidence basis**: The 2026-02-13 fix session explicitly applied both the daemon.json fix AND persistence in `/boot/config/go`. Unraid architecture requires flash-drive persistence for runtime state. The startup_config.sh in this ARA encodes both. +- **Interpretation**: `/boot/config/go` is the standard Unraid mechanism for user-defined startup scripts. It is the correct and only reliable way to persist runtime configuration changes across reboots on Unraid. +- **Dependencies**: C02 +- **Tags**: unraid, persistence, boot-config, iptables, daemon.json + +--- + +## C05: Traefik in bridge-mode Docker cannot use 127.0.0.1 as a backend URL; it must use the host LAN IP or docker0 gateway IP +- **Statement**: When Traefik is running inside a bridge-networked Docker container, configuring a backend service URL as `http://127.0.0.1:PORT` routes to the Traefik container's own loopback, not the host.

Each container receives an IP in the bridge subnet (e.g., `172.17.0.x`). The bridge gateway IP (`172.17.0.1`) is the host's address on that bridge. Outbound traffic from bridge containers to external hosts is NATed by Docker's iptables rules. Inbound traffic from the host LAN to bridge containers requires explicit port mapping or additional iptables rules. +- **Boundary conditions**: Applies to containers launched without `--network host` or a named custom network. Custom bridge networks (e.g., `docker network create`) have separate subnets and separate gateway IPs. The conntrack/NAT behavior that makes `192.168.1.50` unreachable from bridge containers applies specifically to UDP traffic where the source IP would be the host LAN IP — Docker's NAT layer can drop or not properly route the returning UDP packets for bridge-origin queries. +- **Related concepts**: Docker Host Network, docker0 Gateway IP, iptables DNAT + +--- + +## Docker Host Network +- **Notation**: `--network host` +- **Definition**: A Docker network mode where the container shares the host's network namespace. The container binds directly to host interfaces (eth0, docker0, etc.) using the host's IP addresses. No NAT layer exists between the container and the host network. Services in a host-networked container are accessible on all host IPs including `172.17.0.1` (docker0) and `192.168.1.50` (LAN IP). +- **Boundary conditions**: Host-networked containers cannot communicate with bridge containers via Docker internal IPs (`172.17.0.x`) in the normal sense — they must use the bridge gateway or explicit port-mapped IPs. Running Traefik in host mode breaks its ability to use Docker's internal service discovery for bridge containers.

Services running on the host (including host-networked containers like Technitium) that bind to `0.0.0.0` or explicitly to `172.17.0.1` are reachable by bridge containers at this IP. This is the correct address for bridge containers to use when querying Technitium DNS. +- **Boundary conditions**: Only applies to the default bridge network (`172.17.0.0/16`).

It handles internal DNS resolution for the `wylab.me` domain (e.g., resolving `traefik.wylab.me`, `dns.wylab.me`, etc.) and forwards public DNS queries upstream. Because it runs in host mode, it binds to `172.17.0.1` (docker0) and `192.168.1.50` (LAN), but only the docker0 IP is reliably reachable from bridge-networked containers. +- **Boundary conditions**: If Technitium is down, internal `.wylab.me` DNS resolution fails for all clients. Technitium's management UI (`dns.wylab.me`) is itself routed through Traefik, creating the circular dependency.

If either service is unhealthy, the other cannot be fully repaired through normal channels. The circular path is: Traefik needs DNS → Technitium provides DNS → Technitium UI is behind Traefik → Traefik needs valid certs → certs require DNS. +- **Boundary conditions**: The circular dependency manifests most severely during bootstrap (fresh Unraid start with no valid certs) and during cert renewal failures.

Key fields include: `email` (account email), `storage` (path to acme.json), `httpChallenge` or `dnsChallenge` (challenge type), and `resolvers` (explicit DNS servers to use for ACME DNS resolution, bypassing the system resolver). The `resolvers` field is the critical override for breaking the circular dependency. +- **Boundary conditions**: The `resolvers` field is only consulted for DNS queries made during ACME certificate operations, not for general Traefik traffic routing. If `resolvers` is not set, Traefik uses the system's default resolver (which may be Technitium, creating the circular dependency).

It is the standard mechanism for persisting runtime configuration changes (Docker daemon settings, iptables rules, custom mounts, etc.) across Unraid reboots. Because Unraid runs from a USB flash drive, the root filesystem is not persistent — any changes made to files in `/etc/` or runtime state are lost on reboot unless encoded in this script or stored on the flash drive (`/boot/`). +- **Boundary conditions**: Applies only to Unraid installations. Scripts in `/boot/config/go` run as root. Execution order matters — Docker must be running before Docker-dependent commands execute. If the script fails partway through, subsequent commands may not run, so each command should be idempotent or include error handling.

The fix must be applied at the Docker daemon level (`/etc/docker/daemon.json`), not at the container level. The correct DNS server IP for bridge containers is `172.17.0.1` — the docker0 gateway where Technitium (in host mode) actually binds.

This solution does not apply directly to other Linux-based Docker hosts (Ubuntu, Debian, etc.) where `/etc/docker/daemon.json` persists naturally and systemd manages iptables rules. On non-Unraid systems, use systemd unit files or `/etc/rc.local` equivalents. + +--- + +## Known Limitations + +### L1: Single-point DNS dependency +Setting daemon DNS to `172.17.0.1` makes Technitium the sole DNS server for all bridge containers. If Technitium crashes or its container stops, all bridge containers lose DNS resolution entirely (rather than falling back to `1.1.1.1`). Adding a fallback DNS server (e.g., `{"dns": ["172.17.0.1", "1.1.1.1"]}`) would restore fallback behavior at the cost of reintroducing potential latency if `172.17.0.1` becomes temporarily unreachable before the fallback kicks in. + +### L2: Host-networked containers cannot use docker0 gateway +Containers running in host network mode (like Technitium itself, and any other host-networked containers) share the host's network stack and do not route through docker0. They cannot use `172.17.0.1` as their DNS server in the same way bridge containers do — they are *on* the host network, not behind the bridge. Host-networked containers must configure their DNS separately (using `192.168.1.50` or the router's DNS, for example). The iptables DNAT rules address some routing needs for this class of container. + +### L3: Certificate storage must persist +Traefik's acme.json file must be on a persistent volume. If acme.json is inside the container with no volume mount, certificates are lost on container recreation and Traefik must re-request them. Let's Encrypt rate limits (5 certificates per domain per week) make frequent re-issuance problematic. + +### L4: iptables rules are stateful and ordering-sensitive +The DNAT rules added by `/boot/config/go` interact with Docker's own iptables rules. Docker adds and removes iptables rules dynamically as containers start and stop. If boot order causes Docker's rules to be applied after the custom DNAT rules, conflicts may arise. The script must be reviewed against Docker's iptables management to ensure rules are compatible. + +### L5: DNS-01 challenge requires Technitium cooperation +If Traefik uses DNS-01 ACME challenge (instead of HTTP-01), it must add TXT records to the `wylab.me` DNS zone. This requires Technitium to be operational and the Traefik acme provider to have API access to Technitium. The explicit `1.1.1.1` resolver bypass affects only which DNS server Traefik *queries* for Let's Encrypt's server address — it does not affect whether Technitium needs to serve the TXT record for validation. HTTP-01 challenge avoids this dependency entirely. + +--- + +## Assumptions + +- A1: The Unraid server has a stable LAN IP (`192.168.1.50`) that does not change.

Adding `resolvers = ["1.1.1.1:53"]` to Traefik's certificatesResolvers config makes ACME operations independent of Technitium's health. This is a targeted override: it affects only ACME DNS lookups, not general Traefik routing. +- **Sensitivity**: medium — the circular dependency only manifests when Technitium is unhealthy or during fresh bootstrap; in normal operation Traefik can renew certs fine through Technitium. However, it is a silent risk that becomes a critical failure during exactly the worst time (server is degraded). +- **Bounds**: The `resolvers` field must be set per `certificatesResolvers` block.

The failure with `127.0.0.1` is particularly confusing because Traefik doesn't error — it just connects to the wrong place. +- **Bounds**: Applies to host-networked services only. Bridge-to-bridge routing uses Docker's internal DNS (service name) and internal IPs.
