  Project Overview

  Traccar Geocoder — a self-hosted reverse geocoding service. C++ builder parses OpenStreetMap PBF files into binary index files, Rust server
  mmap's them for sub-millisecond queries.

  What We Built (in order)

  1. --admin-only and --no-addresses flags — Builder can produce stripped-down indexes (admin boundaries only, or streets without house numbers).
   Server auto-detects which files are present.
  2. Multi-output builder rewrite — Single PBF parse produces all 3 index modes (full, no-addresses, admin-only) + per-continent subsets. Binary
  cache (--save-cache/--load-cache) avoids re-parsing. --multi-output and --continents flags.
  3. Parallelism improvements (iterative):
    - Parallel deduplication of cell maps (std::async)
    - Parallel index writing — 3 modes written simultaneously
    - Parallel continent filtering — 8 continents processed simultaneously
    - Concurrent admin polygon S2 covering — thread pool processes S2 coverings while PBF reader continues
    - Streaming parallel node processing — producer-consumer queue, workers process PBF blocks in parallel
    - Streaming parallel way processing — same pattern for ways
    - Dense array node index — 100GB+ mmap with MAP_NORESERVE, lockless writes (replaced FlexMem which OOM'd, and sharded FlexMem which had too
  much overhead)
    - Parallel admin polygon assembly — custom ring stitcher replaces osmium's sequential multipolygon assembler, processes 778K relations across
   all cores
  4. Node ID matching for ring stitching — Fixed coordinate-based matching (lossy floats) to use OSM node IDs (exact integers). Stores first/last
   node IDs in way geometry data. Only stores way geometries for admin boundary member ways (~3M vs ~300M total ways).
  5. Ring rotation normalization — add_admin_polygon normalizes ring starting vertex before Douglas-Peucker simplification for consistent output.
  6. Live dashboard — Python HTTP server at localhost:8888 with CPU/memory graphs, elapsed timers (tick between refreshes), log output per node.
  Polls 4 SSH nodes every 30s.
  7. Semantic comparison tool (compare_indexes.cpp) — Decodes binary index files, sorts by canonical keys, compares vertex rings as sets (handles
   rotation/direction), tolerant float comparison.
  8. Kubernetes manifests (k8s/planet-server.yaml) — PVC-backed deployment that downloads planet PBF once and serves via HTTP for other pods.

  Current State of Nodes

  - Node 1 (mich.immich.cloud:30022, 24c/125GB): Running the original sequential code, ~15+ hours in, at 68.7% PBF. SSH: ssh -o
  ControlPath=/tmp/ssh-control/mich -p 30022 mich.immich.cloud
  - Node 2a (10.10.10.12:30022, 48c/192GB cgroup): Just reconnected, fresh pod. SSH: ssh -o ControlPath=/tmp/ssh-control/newbox -p 30022
  root@10.10.10.12. OIDC auth pending (code GKCS-KBJW).
  - Node 2b (10.10.10.11:30022, 48c/192GB cgroup): Available but not connected yet.
  - Node 3 (100.113.88.121, password elon-is-insane, user michtest, 32c/174GB, no cgroup, 50GB swap): SSH: ssh -o
  ControlPath=/tmp/ssh-control/node3 michtest@100.113.88.121. Just finished parallel Germany build. Sequential Germany build should be started.
  Has saved outputs from the old planet run at ~/indexes-old-code/ and ~/planet-old-code.cache.

  The Current Problem

  The parallel admin assembly produces ~12K fewer admin polygons than osmium's sequential assembler on planet data (931,963 vs 943,638). Analysis
   shows:
  - 92K "missing" (in old, not in new)
  - 80K "extra" (in new, not in old)
  - Net: ~12K fewer
  - Spread across all admin levels
  - Top missing names are small plot boundaries

  The node-ID matching fix was just deployed but hasn't been tested on a large dataset yet. The Germany build on node 3 just completed with the
  new code — needs comparison against the sequential version.

  Files on Node 3


[Request interrupted by user]


- ~/pbf/planet.osm.pbf — 86GB planet PBF
  - ~/pbf/germany.osm.pbf — 4.5GB Germany PBF
  - ~/pbf/monaco.osm.pbf — small test PBF
  - ~/indexes-old-code/ — old code planet output (77GB, 943K admin polygons)
  - ~/planet-old-code.cache — old code cache (16GB)
  - /tmp/de-parallel/ — new code Germany output (just completed)
  - /tmp/de-sequential/ — sequential Germany output (should be running or about to start)
  - /tmp/traccar-geocoder/ — latest code (commit acf403e with node-ID fix)
  - /tmp/diff_admin — compiled admin comparison tool
  - /tmp/compare_indexes.cpp — semantic comparison source

  Git State

  Repo: git@github.com:zp-forks/traccar-geocoder.git (branch: main)
  Latest commit: 1a25143 — "fix: use node IDs for ring stitching instead of coordinates"

  Key commits:
  - 93fe6e4 — rename strings to string_pool (s2 namespace conflict)
  - 6fe46b1 — parallel processing with sharded node index
  - 3117db8 — reduce shards to 16, stream way blocks
  - a19cb3c — lockless dense array index
  - 0a2bb57 — increase to 15B max node ID with bounds checking
  - 58349a5 — parallel admin assembly
  - b79a003 — ring rotation normalization + compare_indexes tool
  - acf403e — only store admin member way geometries
  - 1a25143 — node ID matching for ring stitching

  What Needs Doing Next

  1. Compare Germany parallel vs sequential admin polygon counts to see if the node-ID fix resolved the ~12K discrepancy
  2. If it matches, run a full planet build with the new code and compare against ~/indexes-old-code/
  3. If discrepancies remain, investigate which specific relation types our ring stitcher fails on
  4. Run the Rust server against the generated indexes and test queries across 40 global locations (the test script was written but never
  executed on planet data)
  5. Compare index sizes across all modes (full, no-addresses, admin-only) for planet + each continent
  6. The dashboard is running at localhost:8888 on the local Mac

  Memory Constraints

  - Node 2a/2b: 192GB cgroup limit. Dense array (111GB) + data (~30GB) + way processing fits but barely. Previous OOM kills at 175GB (64-shard),
  survived at 168GB (no shards).
  - Node 3: 174GB physical + 50GB swap, no cgroup. Dense array works but previous runs segfaulted when MAX_NODE_ID was 13B (fixed to 15B).
  - /tmp on node 3 is a 79GB tmpfs (RAM-backed). Use ~/ for large files (disk-backed).```


⏺ Good — single sequential build running (PID 8710, 107GB RSS, --no-parallel-admin). Both Germany builds will complete on node 3. The parallel
  one already finished in /tmp/de-parallel/. The sequential one will finish in /tmp/de-sequential/.

  When the next Claude instance picks up, it should:
  1. Wait for the sequential Germany build to finish (it's been running ~12 min, probably another 10-15 min for the admin phase)
  2. Run /tmp/diff_admin /tmp/de-parallel /tmp/de-sequential to compare admin polygon counts
  3. If they match (or are very close), proceed to planet build
  4. If they differ significantly, investigate the ring stitching further

  The parallel Germany build took about 3 minutes. The sequential one will take ~20-30 minutes (the admin boundary phase is the bottleneck). The
  comparison will show whether the node-ID fix resolved the discrepancy.


Let me check the status of the sequential build on node 3 and compare the results.

The container doesn't have `/dev/net/tun` available — Tailscale needs TUN device support. Let me try userspace networking mode instead.


ls /dev/net/tun 2>&1; cat /proc/1/cgroup 2>/dev/null | head -5

Check TUN device and container type


ls: cannot access '/dev/net/tun': No such file or directory
0::/


Got it — Docker container without TUN. Let me run Tailscale in userspace networking mode.


pkill tailscaled 2>/dev/null; sleep 1
tailscaled --tun=userspace-networking --state=/var/lib/tailscale/tailscaled.state --socket=/var/run/tailscale/tailscaled.sock &
sleep 3
echo "--- daemon status ---"
tailscale status 2>&1 || true

Start tailscaled with userspace networking

Tailscale is connected to the immich tailnet. I can see `michtest-ng` at `100.113.88.121` (node 3) is online.

Note: Tailscale is in userspace networking mode (no TUN device in this container), so you'll need to use `tailscale nc` or the SOCKS proxy to connect to tailnet IPs rather than direct SSH. Let me test connectivity to node 3.


Ping node 3 via tailscale


Add bypass permissions mode as the default permission mode for claude, then we will restart hte session and resume from there


Skill

Set the default permission mode to bypass (allowedTools: ["*"])


Launching skill: update-config
