fix: refine inner-way fallback to avoid merging holes with outer boundary

Only retry with all-role ways when the relation has NO outer/empty-role way
geometries at all. When outer ways exist but don't close, including inner
ways creates merged outer+hole geometry (e.g., Reislingen). The no-outer
fallback handles Jersey parishes, Ukrainian villages, and similar cases
where the boundary IS tagged as inner role.

Remaining 4 missing (Albanian villages: Dardania, Lakrishtë, Qafa, Qendra)
need inner ways to bridge gaps between outer ways — requires osmium's full
segment-level assembly with inner/outer containment testing to handle.

name: string_interleave_bug
description: Critical bug found in parallel way processing - interned_strings were interleaved by type but merge assumed grouped order
type: project
---

Found and fixed a critical bug in the parallel way processing string interning (2026-03-21).

The parallel worker code pushed way names, building address strings, and interpolation street names
into a single `interned_strings` vector in interleaved processing order (as items appeared in each
PBF block). The merge code at line ~2195 read them assuming they were grouped by type: all way names
first, then all building addr strings, then all interp strings. This caused name misassignment
whenever a PBF block contained mixed types (highways + building addresses + interpolations).

**Impact**: ~62% of ways in Germany had incorrect name assignments. The bug was non-deterministic
across runs because parallel thread scheduling affected which blocks went to which thread, changing
the interleaving pattern.

**Fix**: Split `interned_strings` into `way_strings`, `addr_strings`, and `interp_strings` vectors.
Each merge loop indexes its own type-specific vector.

**Why:** The sorted raw node coordinates matched 100% between builds, proving the coordinate data
was correct — only the string assignments were wrong.

**How to apply:** This fix is in commit 3984d21 (local only, not pushed to GitHub yet due to missing
SSH key in the container). The fix needs to be pushed when git access is available.

name: validation_state
description: Current validation state of parallel assembly - Europe test results and remaining gaps
type: project
---

As of 2026-03-21, the parallel admin assembly has been validated against the baseline
(pre-parallel sequential code) on both Germany and Europe PBFs.

**Europe results** (31GB PBF):
- Ways: 19,452,480 — 100% match
- Addresses: 85,891,830 — 100% match
- Interps: 13,988 — 100% match
- Admin unique name|level: 327,850 matched, 4 missing (Albanian villages), 27 extra

**4 remaining missing admin boundaries** (all Albanian level-10 villages):
- Dardania, Lakrishtë, Qafa, Qendra
- Root cause: inner-role ways bridge gaps between outer-role ways
- Our fallback only retries with all roles when there are NO outer ways
- Full fix requires osmium's segment-level assembly with inner/outer containment testing

**Germany results**: 43,222 vs 43,221 (net +1, same 3 freq diffs as before)

**Why:** The remaining 4 Albanian cases have outer ways that don't close AND inner ways
that complete the ring. Including inner ways globally creates false polygons (Reislingen
merges hole with outer boundary). Only osmium's full segment graph can correctly handle this.

**How to apply:** These results are documented in builder/test/VALIDATION_REPORT.md.
14 unpushed commits on main branch.

The OIDC approval timing keeps expiring before the SSH handshake completes. The tool output → you → browser → approve → server validate loop is too slow.

The best approach is for you to run it directly so you see the code instantly:

```
! ssh -o ControlMaster=no -o ControlPath=none -o NumberOfPasswordPrompts=1 node2a "echo connected && hostname"
```

Then approve the code the moment you see it in the terminal. Once connected, I can take over from there.

Alternatively, if node 3 still has time, I can keep working there. Is node 3 still available?


node 3 will be offlije in a few minutee, however itll be back up afyer an indeterminite amount of time, so you can keeo.monitoring until it is avaioable again then continue afyer that

Node 3 (michtest-ng, 100.113.88.121) going offline ~2026-03-22, back at indeterminate time.

**When it comes back, do these in order:**

1. **Re-establish SSH master**: `sshpass -p 'elon-is-insane' ssh -M -o ServerAliveInterval=30 node3 "sleep 99999" &`

2. **Check if builds survived**: `ls ~/europe-parallel2/ ~/europe-baseline/` — these are on disk (/dev/vda1), should survive reboot

3. **Run Europe comparison with latest code** (commit 4b46e99 has inner-way fallback + border-line fix):
   - Build: `cd /tmp/traccar-geocoder/build && make -j$(nproc)` (need to re-upload source since /tmp is tmpfs)
   - Run: `build-index ~/europe-parallel-final ~/pbf/europe.osm.pbf --parallel-admin`
   - Compare: `/tmp/dedup_compare ~/europe-parallel-final ~/europe-baseline`
   - Expected: 4 missing (Albanian villages), ~27 extra

4. **Push commits**: 14 unpushed commits on main. Need GitHub SSH key or user to push.

5. **Update VALIDATION_REPORT.md** with final Europe numbers

**Files on disk (survive reboot):**
- ~/pbf/europe.osm.pbf (31GB)
- ~/pbf/germany.osm.pbf (4.5GB)
- ~/europe-baseline/ (baseline Europe index)
- ~/europe-parallel/ (first parallel Europe index)
- ~/europe-parallel2/ (parallel with role fix)
- ~/de-baseline-n3/ (baseline Germany index)

**Files on tmpfs (LOST on reboot):**
- /tmp/traccar-geocoder/ (source code + build)
- /tmp/traccar-geocoder-baseline/ (baseline binary)
- /tmp/de-parallel-*, /tmp/de-sequential-* (Germany test indexes)
- /tmp/compare_indexes, /tmp/diff_admin (comparison tools)

Got it. I'll monitor node 3 and resume when it's back. The Europe baseline and parallel indexes are on disk (`~/europe-baseline/`, `~/europe-parallel2/`) so they'll survive the reboot. Only `/tmp` (source code, binaries, comparison tools) will be lost and need re-uploading.

Let me start monitoring.


Bash

Check if node 3 is still up


Command running in background with ID: b0a7l738x. Output is being written to: /tmp/claude-0/-root-traccar-geocoder/af1c4baa-0f9a-4420-a8b3-ce20dc28c8b9/tasks/b0a7l738x.output


sleep 5 && cat /tmp/claude-0/-root-traccar-geocoder/af1c4baa-0f9a-4420-a8b3-ce20dc28c8b9/tasks/b0a7l738x.output 2>/dev/null

Check result


(Bash completed with no output)


Check master connection


Error: Exit code 255
Control socket connect(/tmp/ssh-mux/node3): No such file or directory


Master is gone. Let me try re-establishing.


sshpass -p 'elon-is-insane' ssh -o ConnectTimeout=10 -M -o ServerAliveInterval=30 node3 "echo up; hostname" 2>&1

Try to reconnect to node 3


Error: Exit code 255
Connection timed out during banner exchange
Connection to UNKNOWN port 65535 timed out


Node 3 is offline. I'll check back periodically.


sleep 300 && sshpass -p 'elon-is-insane' ssh -o ConnectTimeout=10 node3 "echo up" 2>&1

Check node 3 in 5 min


sleep 600 && sshpass -p 'elon-is-insane' ssh -o ConnectTimeout=10 node3 "echo up" 2>&1

Check node 3 in 10 min


The user doesn't want to proceed with this tool use. The tool use was rejected (eg. if it was a file edit, the new_string was NOT written to the file). STOP what you are doing and wait for the user to tell you how to proceed.

Note: The user's next message may contain a correction or preference. Pay close attention — if they explain what went wrong or how they'd prefer you to work, consider saving that to memory for future sessions.


[Request interrupted by user for tool use]


Alright, I would like you to test the version that should exactly match and fix the albanian areas. My main priority is maintaining parity with the original code, while of course making it significantly faster with the parallel iomprovements. Missing four areas in albania isn't ideal, that doesn't respresent an exact match with what we currently have for the current build process


You're right. Let me fix the Albanian cases properly. The issue is distinguishing valid inner-way bridging (Albanian villages) from invalid hole-merging (Reislingen). The key: when the all-ways retry produces a ring, check if any coordinate appears more than once — that indicates a spike or figure-8 from merging a hole with the outer boundary.
