Dashboard Qualification Status

San Gabriel appears in the dashboard only as a deficient source candidate. Double Mountain Fork Brazos (12050004) is a four-project source qualification candidate after all four selected two-core 1% AEP plans reached unsteady computation. Middle Chattahoochee–Lake Harding (AL03130002) is one source and geometry qualification candidate for its complete 197-model 1D steady corpus; no hydraulic computation has been run for that corpus. Each candidate name links to its qualification record. Austin–Oyster (12040205) is an unsteady-start-qualified source and geometry candidate after plan p08 passed the bounded pre-compute workflow. Upper Guadalupe (12100201) is a four-project partially qualified source candidate: UPGU1 reached unsteady solver startup, while UPGU2–UPGU4 remain unqualified. The San Gabriel, Double Mountain Fork, and Upper Guadalupe entries retain project-specific sub-model links. These evidence links are not project-viewer links and must not imply that the public delivery has a published result viewer. Pedernales (12090206) is one qualified source and geometry corpus for its 530-project 1D steady corpus; its single map outline is the exact union of all active model footprints. Cibolo (12100304) is one organized 2D source candidate with delivered terrain. Medina (12100302) is one grouped five-model study: four projects contain their compiled modified terrain, while Upper Medina Headwaters is explicitly blocked by a critical missing-terrain gap.

Source RAS Commander entry point Qualification Known limitation
FEMA San Gabriel BLE (12070205) RasEbfeModels.organize_model("san-gabriel") Five linked HEC-RAS 6.3 projects; one 1% plan per project reached unsteady computation. A reconstructed-terrain LBSG_503 1% run also completed successfully with a 0.0236% volume error and 0.737-ft P95 maximum-WSE difference from the supplied result. LBSG_504 covers Round Rock and LBSG_503 is the Florence-area project. This is compute evidence only. Critical, model-blocking source gap: the compiled Terrain\Terrain.hdf and its road-crossing/Lake Georgetown modification payloads were not provided. The HDEM-only reconstruction resolves paths and supports diagnostic QA, but does not make the public 2D model reproducible or usable downstream.
FEMA Double Mountain Fork Brazos eBFE (12050004) RasEbfeModels.organize_model("double-mountain-fork-brazos") Four chained HEC-RAS 6.10 projects (HEC-RAS 6.1 family). Exact API-derived footprints are published here, and all four selected two-core 1% AEP plans reached unsteady computation with owned_process_artifacts evidence and no timeout or error. This is source-qualification evidence, not a completed-result viewer. Hydraulic inputs and compiled terrain are delivered. DMF2 correctly references Terrain.Clone (1).hdf with the Polygons (1) elevation modification. DMF1/DMF2 g01 require native RasMap reassociation plus HEC-RAS table recomputation in the validation copy. Remaining nonhydraulic gaps are local basemap/profile-line references and an inaccurate DMF1 result count in Readme.txt.
FEMA Austin–Oyster eBFE (12040205) RasEbfeModels.organize_model("austin-oyster") One HEC-RAS 5.07 2D unsteady project with seven plans. Plan p08 (1PAC) passed the bounded pre-compute workflow with two cores: an owned RasUnsteady64.exe and the complete fresh preprocessing artifact set were detected in 64.9 seconds. This is solver-start evidence, not a completed-result claim. Reconstruction relocates fourteen Output assets and the projection, then corrects one RASMapper projection path. All 28 audited plan-HDF path attributes were already path-equivalent and were preserved byte-for-byte. The two genuinely undelivered references are display-only Google Map.xml and Google Hybrid.xml. The delivered terrain has no modification groups and the .rasmap references none.
FEMA Upper Guadalupe eBFE (12100201) RasEbfeModels.organize_model("upper-guadalupe") Four cascading HEC-RAS 6.3.1 2D unsteady projects, each with seven plans. Four exact API-derived model footprints and durable UPGU1–UPGU4 deficiency links are published here. UPGU1 p01 reached owned unsteady-solver startup in a fresh two-core run. UPGU2's receipt records natural_completion without owned solver-start evidence after property-table rebuilding was observed; UPGU3–UPGU4 were not attempted. Supplied plan HDFs remain published artifacts, not fresh execution evidence. The archive is CRC-clean and includes all four modified-terrain triplets. UPGU1–UPGU3 retain channel modifications; UPGU4 retains channel and polygon modifications. Reconstruction applies 344 unique staged actions and rewrites 224 fixed-length HDF association attributes, including 28 geometry-HDF attributes omitted by the source audit. Twenty-one omitted files are display/result/QC assets and do not include terrain or hydraulic startup inputs.
Alabama Middle Chattahoochee–Lake Harding BLE (AL03130002) AlabamaBleModels.organize_watershed("03130002", ...) One portable delivery contains 197 1D steady projects in eight source basins, 197 registered plans and geometry HDFs, and 5,365 cross sections. The landing outline is the union of all individual model footprints; one staged PMTiles derivative combines their geometry. This is source and geometry evidence only; no plan computation or result viewer has been qualified. The publisher's bare object-store prefixes return 404, so discovery must join the Alabama ArcGIS model and link records and use only each link's public WebPath. One extra physical plan file, OSANIPPA CREEK.p02, is not registered by its project. Delivered plan metadata records 135 projects at 6.20, two at 6.31, and omits the version for 60.
FEMA Pedernales eBFE (12090206) RasEbfeModels.organize_model("pedernales") One HUC8-level discovery entry represents 530 independent HEC-RAS 4.1 1D steady projects. The landing outline is the exact union of all 530 active geometry footprints, derived through HdfProject from compiled geometry HDF where delivered and the plain-text fallback otherwise. All 530 selected p01 runs passed in isolated two-core HEC-RAS 6.6 copies. Eight delivered HDF/compute-message assets require exact-copy placement in three referenced project folders. Terrain is not applicable to this pure 1D steady corpus. HEC-RAS 4.1 was unavailable, so qualification does not assert native-version numerical equivalence. No hosted four-layer geometry PMTiles or completed-result viewer is claimed.
FEMA Cibolo eBFE (12100304) RasEbfeModels.organize_model("cibolo") One HEC-RAS 5.0.7 2D unsteady project with seven plans. Its exact API-derived g05 footprint is shown here; the organizer closes the active p14 source references, and p14 reached owned unsteady-solver startup with two cores. This entry does not claim completed results. The delivered compiled terrain and land cover are present and no terrain modification groups are referenced. Reconstruction extracts the nested delivery, relocates seven DSS assets, rewrites seven active DSS paths, and corrects the RASMapper projection path. Five remaining references are backup/display-only.
FEMA Medina eBFE (12100302) RasEbfeModels.organize_model("medina") One grouped row retains five exact API-derived 2D model polygons. Leon1, Leon2, Leon3, and Middle/Lower Medina are source-complete and each selected plan reached owned unsteady-solver startup with two cores. Upper Medina Headwaters remains visibly blocked and is not represented as qualified. Critical, model-blocking source gap for Upper Medina Headwaters: its active geometry requires a compiled Terrain.hdf with UpperMedinaHW_TerrainModifications, but that file is absent. The other four projects include their compiled channel-modified terrain. The publisher ZIP is also truncated inside one supplied Upper Medina result HDF; that separate result defect is not the hydraulic source blocker.

San Gabriel retains unsteady_start evidence but has delivery-readiness status critical_source_gap. It must not be published as a runnable example until the original compiled terrain, or complete source-equivalent terrain/modification inputs, are recovered and verified and the remaining publication gates pass. The organizer normalizes all five .rasmap files so their 40 terrain and modification references resolve to the single expected organized target, RAS Model\Terrain\Terrain.hdf, and creates a durable Record of Deficiencies for any explicitly authorized reconstruction.

Double Mountain Fork Brazos keeps its supplied compiled terrain intact. In particular, DMF2's modified Terrain.Clone (1).hdf is not missing and must not be silently replaced by the unmodified terrain. The first organizer incorrectly redirected valid outer terrain and land-cover references to incomplete Input copies; identical Geometry Writer failures on network and local-disk validation copies proved this was not a network/path-length problem. The specialized organizer now preserves the delivered outer references. Its Record of Deficiencies records the four-project chain, deterministic assembly repairs, 4/4 native unsteady-start qualification, and the remaining publication gates.

Middle Chattahoochee–Lake Harding is deliberately represented by one outline and one table row, not 197 dashboard entries. Its combined geometry PMTiles must remain separate from the canonical, portable FIM inventory and will load only after the staged archive is published at a validated HTTP byte-range URL. The Record of Deficiencies records the source enumeration constraint, the orphan plan file, mixed version metadata, immutable source layout, and the current no-computation boundary.

Austin–Oyster is qualified for source/geometry discovery and an unsteady-start example claim, but not for a completed-results viewer. The Record of Deficiencies reconciles the webmap's proposed 29 metadata edits with the independent finding that all 28 HDF attributes were already correct, records the two display-only omissions, and preserves the independent CEWS pre-compute evidence.

Upper Guadalupe is represented by four exact project polygons and one grouped suite row. The Record of Deficiencies records the single-archive reconstruction, confirms delivery of hydraulically material terrain modifications, separates supplied result artifacts from fresh runtime evidence, records UPGU1's successful p01 pre-compute gate, and keeps UPGU2–UPGU4 explicitly unqualified. Until a hosted viewer is requalified, the suite and its four subprojects link to that durable record rather than dead viewer manifests.

Pedernales is represented by one exact union outline and one table row, not 530 dashboard rows. The Record of Deficiencies keeps source organization, per-project execution, and corpus-wide acceptance as separate gates. A combined geometry archive remains a local staging product until it has a real immutable public URL and passes the PMTiles layer, zoom, metadata, and HTTP byte-range validators.

Cibolo's Record of Deficiencies records the nested extraction, active DSS and projection repairs, delivered terrain finding, and bounded execution evidence. Its dashboard link remains a source-evidence link rather than a result-viewer link.

Medina is represented by five exact polygons and one grouped suite row. Its Record of Deficiencies distinguishes the four source-complete projects from Upper Medina Headwaters. The latter's footprint is useful discovery geometry, but does not make the model runnable: the missing compiled modified terrain is a critical 2D source gap.
