| # How MunicipalBench Final Gold was obtained |
|
|
| Final gold is the resolved annotation used for scoring. Human first passes |
| supplied the candidate labels and boxes. Agreement rules resolved compatible |
| submissions; disputed cases could pass through semantic matching, VLM voting or |
| explicit human adjudication. Earlier manager selections were preserved. These |
| routes are recorded per image, so final gold does not imply that all annotators |
| originally agreed or that every image underwent the same review. |
|
|
| Each row represents one usable synthetic image. Read `kind` together with |
| `edit_summary.resolution.method_id`, `method_name` and `method_version`. The |
| same `accepted` kind covers both historical manager selections and later |
| explicit adjudication; kind alone is insufficient to identify the method. |
|
|
| ## Population and method counts |

|
| | Method | Ordinary synthetic | Traps | Total | |
| | ------------------------------------- | -----------------: | ------: | ---------: | |
| | GT-001: Auto-agreement | 4,232 | 123 | 4,355 | |
| | GT-002: Rating resolution | 1,177 | 45 | 1,222 | |
| | GT-003: Semantic resolution | 30 | 2 | 32 | |

| | GT-008: Historical manager acceptance | 1,315 | 108 | 1,423 | |
| | **Total** | **10,838** | **696** | **11,534** | |
|
|
| GT-006 denotes confirmed unusable images and GT-007 denotes unresolved work. |
| Neither is included in Final Gold. Real controls are also outside this release. |
| There are 7,836 positive and 3,002 negative ordinary synthetic images, and 619 |
| positive and 77 negative traps: 8,455 positives and 3,079 negatives overall. |
|
|
| ## GT-001: Original or recovered auto-agreement |
|
|
| Export kind: `auto_agreed`; method name: `original_auto_agreement`. |
|
|
| Require compatible report states, identical violation-label sets, plausibility |
| and naturalness differences at most 1, and the native box-agreement statistic at |
| least 0.7. Agreed usable negatives have no box-IoU requirement. |
|
|
| The original submission hook considers exactly two first-pass annotations when |
| gold is absent. It takes labels and boxes from the first annotation in sorted |
| source-ID order and uses rounded rating midpoints. Exact half-integers use |
| Python's nearest-even rounding. Existing records retain their original labels, |
| boxes and ratings. |
|
|
| This release contains 4,354 existing records and one recovered agreement. The |
| recovered record passes label/geometry criteria for every available rater pair |
| and rating ranges at most 1. It keeps the first sorted human's labels/boxes and |
| the rounded midpoint of the first two humans' ratings. `resolution.origin` |
| distinguishes `existing_gold` from `recovered_from_iaa`. |
|
|
| ### Native geometry used by GT-001, GT-002 and GT-003 |
|
|
| For each shared label, take the maximum IoU among all cross-annotator box pairs. |
| Average those label maxima, round to three decimals, and compare with 0.7. This |
| is not a one-to-one instance assignment or an unmatched-box-zero score. It can |
| pass despite different instance counts or disagreement on extra boxes. Passing |
| it must not be described as full instance consensus. |
|
|
| ## GT-002: Conservative rating resolution |
|
|
| Export kind: `rating_resolved`; method name: `conservative_rating_resolution`. |
|
|
| Require identical labels and passing native geometry for every rater pair. At |
| least one rating dimension has a range greater than 1; otherwise the case |
| belongs to recovered GT-001. Keep the first sorted human's labels and boxes. Set |
| plausibility and naturalness independently to the minimum across all supplied |
| raters (`minimum_all_annotators`). No VLM call is needed. |
|
|
| The minimum is an explicitly conservative policy, not evidence that the lower |
| rating is correct. The native geometry limitation above remains applicable. |
|
|
| ## GT-003: Direct semantic resolution |
|
|
| Export kind: `semantic_resolved`; method name: `direct_semantic_resolution`. |
|
|
| Use the 44 algorithmically accepted direct pairs in the distributed semantic |
| policy. Acceptance means cosine similarity above 0.80, not expert validation. |
| There is no transitive closure: accepting A/B and B/C does not imply accepting |
| A/C. Lock exact labels common to all raters. Require a complete one-to-one |
| mapping of the remaining labels where every pair in each group is identical or |
| directly accepted by that policy. Every rater pair must pass native geometry |
| after mapping. Search in sorted label order and choose the first passing |
| mapping. |
|
|
| Keep the first sorted human's original labels and boxes, without rewriting them |
| to an umbrella class. Both ratings use the minimum across all raters, even where |
| the original ratings were already within tolerance. |
|
|
| ## GT-004: Independent council over human proposals |
|
|
| Export kind: `vlm_resolved`; method name: `independent_vlm_council`; method |
| version: `5.1.0`. |
|
|
| | Judge slot | Model | Provider | |
| | ---------: | ------------------------------ | ---------------- | |
| | 0 | `deepseek/deepseek-v4.1-flash` | `deepinfra/fp8` | |
| | 1 | `meta-llama/llama-4-maverick` | `deepinfra/base` | |
| | 2 | `qwen/qwen3.8-27b` | `deepinfra/bf16` | |
|
|
| The final protocol is `batched_verification_v1`, restricted to |
| `supplied_human_annotations_only`. Judges independently see the original image, |
| human proposal panels and violation definitions. Each judge supplies a batch of |
| categorical ballots for the image. Models assess presence and adequacy of |
| existing boxes; they generate no new labels, coordinates, instances or |
| confidence scores. Missed-instance and coverage-discovery votes are ignored. |
|
|
| Group exact labels and unambiguous direct semantic aliases before voting. |
| Preserve an agreed instance only when the first human's box has a unique match |
| in every other rater at IoU at least 0.7, reverse matches are unique, and every |
| matched pair also reaches 0.7. Retain that original human box. Extra or |
| ambiguous instances remain contested. This preservation rule is stricter than |
| the native geometry statistic used in GT-001/002/003. |
|
|
| Contested labels receive `present`, `absent` or `uncertain` votes. Proposals |
| receive `keep`, `reject_absent`, `redundant`, `inadequate` or `uncertain` votes. |
|
|
| - `joint_presence_and_box_vote`: at least two judges jointly support label |
| presence and retaining that box. |
| - `majority_label_absence`: at least two valid judges reject a label supplied by |
| only some humans; remove its disputed proposals. |
| - `majority_region_absence`: given a positive label majority, at least two valid |
| judges reject the particular region. |
| - `majority_existing_replacements`: at least two positive judges identify |
| retained same-label proposals that cover the redundant proposal. |
|
|
| All-human presence or a locked reference cannot be overturned automatically by a |
| majority absence vote. Replacement references must identify directly retained |
| same-label proposals; self-references, chains and cycles do not justify removal. |
| Overlapping alternatives require two judges jointly supporting their retention. |
| Ambiguous semantic overlaps require human review. |
|
|
| Missing, malformed or contradictory ballots abstain for the affected label. |
| Inadequate boxes without supported replacements, insufficient majorities and |
| remaining contradictions go to human review. Only fully resolved images receive |
| GT-004 gold. Zero retained violations becomes an explicit clean negative. |
| Ratings use the minimum across all humans. |
|
|
| `label_decisions` records ballots and decisions; `source_proposals` records the |
| original labels, boxes and source references; `human_agreements` records |
| mappings and locked instances. The ordered `judges` list decodes judge indices. |
| Compatible earlier ballots may be replayed under the final protocol; |
| `replay_source` retains the run ID, with the private local path removed. |
|
|
| ## GT-005: Explicit human adjudication |
|
|
| Method name: `human_adjudication`; version: `manager-review-1.0.0`. |
|
|
| A manager explicitly approved the final labels, boxes and ratings after image |
| inspection. Human-selected ratings supersede the automatic minimum-rating |
| policy. |
|
|
| | Kind | Starting basis | Synthetic | Traps | Total | |
| | ---------- | ------------------------ | --------: | ------: | --------: | |
| | `accepted` | One annotator, unchanged | 699 | 70 | 769 | |
| | `edited` | One annotator, modified | 143 | 25 | 168 | |
| | `authored` | Human union | 106 | 18 | 124 | |
| | `authored` | Blank annotation | 20 | 2 | 22 | |
| | **Total** | | **968** | **115** | **1,083** | |
|
|
| The manager may add, remove or redraw boxes, change labels and ratings, or |
| explicitly mark no violations. Union basis does not mean every union box was |
| retained. Only completed adjudications are included; drafts and reopened reviews |
| are excluded. The export was checked against completed review revisions. |
|
|
| Preserve `review_revision`, `source_run_id`, `basis`, |
| `status: manager_reviewed`, `platform_status: gold_set` and |
| `rating_policy: human_adjudicated`. The status describes this human-reviewed |
| route, not every automatic record. |
|
|
| ## GT-008: Historical manager acceptance |
|
|
| Export kind: `accepted`; method name: `existing_manager_acceptance`. |
|
|
| A manager selected a supplied human annotation as gold in the original platform. |
| Preserve its payload and agreement snapshot, adding the resolution wrapper with |
| `origin: existing_gold`. Do not imply an automatic-agreement pass or |
| retrospectively apply the later minimum-rating policy. |
|
|
| The release-wide `accepted` kind totals 2,192: 1,423 historical GT-008 |
| selections and 769 GT-005 approvals. GT-001/002/003/008 use wrapper version |
| `1.0.0`; this does not identify the original annotation platform's software |
| revision. |
|
|
| ## Interpretation |
|
|
| `agreement_at_gold` preserves the original snapshot, generally calculated from |
| the first two source annotators. It is not a fresh comparison against final gold |
| or proof of correctness. Historical null snapshots remain null. Use the supplied |
| first-pass annotations for independent agreement analysis rather than treating |
| gold as an additional rater. |
|
|
| Conservative minima, model majorities and manager decisions are fallible. Report |
| method composition and the potential dependence when an evaluated model also |
| served on the council. Model performance is reported separately from these |
| ground-truth construction methods. All totals here describe only the distributed |
| synthetic population. |
