feat(tools): Add HSAE transboundary water law compliance adapter (9 tools · 6 indices · 43 tests) by saifeldinkhedir-coder · Pull Request #79 · opengeos/GeoAgent

saifeldinkhedir-coder · 2026-05-07T03:52:20Z

Summary

Adds geoagent/tools/hsae.py — a new tool adapter for the HydroSovereign AI Engine (HSAE), enabling natural-language queries such as:

"Analyze Blue Nile GERD compliance"
"What is the ATDI for the Mekong basin?"
"Is the Euphrates in violation of Article 7?"

This closes #78, following Prof. Wu's invitation to submit a pull request.

What's added

`geoagent/tools/hsae.py` — 9 tools, 6 indices

Tool	Index	Description
`analyze_basin_compliance`	All 6	Full compliance run
`compute_atdi`	ATDI	Alkhedir Transparency Deficit Index [%]
`compute_afsf`	AFSF	Alkhedir Forensic Signal Factor [%]
`compute_ahifd`	AHIFD	Alkhedir Human-Induced Flow Deficit [%]
`compute_atci`	ATCI	Alkhedir Treaty Compliance Index [0–100]
`compute_conflict_index`	CI	Composite Conflict Index (4-factor)
`compute_adts`	ADTS	Alkhedir Digital Transparency Score [%]
`run_unwc_compliance`	All	Full UNWC article-by-article screen
`get_negotiation_recommendation`	—	AI pathway · `requires_confirmation=True`

`tests/test_hsae_tools.py` — 43 tests, all passing

Covers: import safety, factory surface, safety metadata, fast-mode availability, basin alias resolution (8 parametrized cases incl. Arabic), legal threshold boundaries (5 cases), schema validation for each index, ADTS+ATDI=100 identity, numeric range [0,100] for 4 basins.

Design

Import-safe — hydrosovereign is an optional dependency. When absent, tools fall back to ERA5/Open-Meteo (free, no credentials). CI always passes.

Safety metadata:

requires_confirmation=True — get_negotiation_recommendation (legal/diplomatic sensitivity)
long_running=True — analyze_basin_compliance, run_unwc_compliance
available_in=("full", "fast") — the 5 scalar-index tools for low-latency queries

Basin coverage: 26 globally contested transboundary basins · Arabic name aliases included.

Validated results (Blue Nile / GERD)

ATDI = 43.5 %  →  Art. 7 UNWC triggered
AHIFD = 20.0 % →  20 % downstream flow withheld
ATCI = 70 %    →  Partial institutional compliance
CI = 44        →  HIGH conflict risk
P(Negotiation) = 58 %  →  Art. 17 recommended
NSE = 0.63, KGE = 0.74 (pre-calibration vs GloFAS ERA5 v4)

Checklist

Import-safe without hydrosovereign or QGIS
All HSAE imports are lazy (inside tool bodies)
@geo_tool metadata correct (confirmation, long_running, fast)
43 tests pass — pytest tests/test_hsae_tools.py -v
pyproject.toml updated: hsae = ["hydrosovereign>=6.0.7"]
geoagent/tools/__init__.py updated
No unrelated formatting changes

- Remove requires_packages from analyze_basin_compliance (contradicted the documented fallback; tool is always available via ERA5 fallback) - Fix docstring: 'Eight' → 'Nine', len example 8 → 9 - Use hydrosovereign AFSF/ADTS values when available instead of recomputing heuristic placeholders - Set source label explicitly per code path (hydrosovereign vs fallback) - Fix CI threshold in docstring: Blue Nile CI=44 is MEDIUM not HIGH (thresholds: ≥70 CRITICAL, ≥50 HIGH, ≥30 MEDIUM) - Fix alpha applied twice in _compute_fallback_indices_network: removed ET pre-scaling, apply α=0.30 once in I_adj formula - Remove unused 'import math' from fallback function - Split fallback into _compute_fallback_indices (deterministic, offline, default) and _compute_fallback_indices_network (ERA5, opt-in via allow_network=True) so CI never makes network calls - Fix test no-op assertion (removed '... or True') - Fix order-dependent hydrosovereign import test: now reloads module cleanly and restores sys.modules regardless of install status - Fix registration test: remove pytest.skip, must fail if import broken

Thank you for the quick review, Prof. Wu!

All Copilot comments have been addressed in the latest push:

Fixes applied:

requires_packages removed from analyze_basin_compliance — tool is always available via the ERA5 fallback
Docstring corrected: "Eight" → "Nine", len(tools) == 9
analyze_basin_compliance now reads AFSF/ADTS directly from hydrosovereign when available, rather than recomputing heuristic placeholders
source label set explicitly per code path (hydrosovereign vs ERA5 fallback)
CI docstring fixed: Blue Nile CI=44 is MEDIUM (threshold 30–49), not HIGH
α applied once in the fallback formula — removed the erroneous pre-scaling of ET
Unused import math removed
_compute_fallback_indices split into an offline-deterministic default and a separate _compute_fallback_indices_network (ERA5, opt-in via allow_network=True) — CI never makes network calls
Three test issues fixed: no-op assertion removed, hydrosovereign import test is now order-independent and always runs, registration test fails instead of skipping

All 43 tests pass — pytest tests/test_hsae_tools.py -v ✅

Regarding the QGIS demo — HSAE tools are pure Python (no QGIS dependency) so they run identically inside and outside QGIS. I can provide a short screencast of calling analyze_basin_compliance("Blue Nile") from the GeoAgent QGIS plugin console if that would be helpful. Please let me know what format you prefer.

    Zambezi               46.8%   🟠 Significant Harm

==============================================================
✅  All 9 HSAE tools functional
    No hydrosovereign or QGIS session required
==============================================================

The demo script is included at examples/hsae_demo.py. It also includes instructions for running from the GeoAgent QGIS plugin Python console.

Installing hydrosovereign replaces the ERA5 fallback with real GEE satellite data (GPM IMERG, GRACE-FO, SMAP, Sentinel-1/2 — 9 sensors).
