Irish `ga` / `ga-IE` is not Gã. Pass ISO 639-3 `gaa` or `gaa-GH` / variety `gaa-gh`. Dangme (`ada`) is never interchangeable.
license_warnings
  • Ga corpus TTS (ghanaopenai/ga-multispeaker-speech-text-20k unit bank) is CC-BY-NC-4.0 — unrestricted commercial redistribution of those assets is blocked.
  • Whisper-medium Ga ASR (obour/whisper-medium-ga-multispeaker-ghana) — pin versions and attribute per model card.
  • Meta MMS has Ga NLP only — facebook/mms-tts-gaa does not exist; do not invent MMS-TTS claims.
  • Phrase/lexical Baobab MT covers reviewed corridor domains; neural_nmt is false (no Ga NLLB service shipped).

research · acceptance_gates

Generative LM research slot

Research slot + harness + training recipe only. Do not brand phrase MT or speech corridors as a full national LLM. Generative inference unsupported until gates are met and Lugemi-owned weights exist.

acceptance_gates

  • held_out_speakersrequired truemet false

    Held-out evaluation speakers must never appear in training exports; speaker lists remain empty until consented collection.

  • community_consent_accra_garequired truemet false

    trainingEligible stays false until Accra / Ga Mashie community speakers re-confirm for training.

  • dangme_separationrequired truemet false

    Any future LM/adapters must ship as baobab-ga-accra-* — never one blob marketed as Ga+Dangme.

  • beat_phrase_mt_baselinesrequired truemet false

    Generative claims require held-out gains vs corridor phrase-MT baselines on declared Ga-native tasks.

  • commercial_rights_clearrequired truemet false

    Base model + data licenses must clear commercial ministry/enterprise redistribution before promotion.

training_eligible_unlock

trainingEligiblefalse
statuslocked

trainingEligible remains false until all gates are met with durable evidence. Do not invent consent. Irish ga is never Ga.

  • community_consent_accra_garequired truemet false

    Accra / Ga Mashie community speakers must reconfirm training export consent.

    evidence_required Signed Accra Ga contributor agreements reconfirming training use

  • held_out_speaker_listsrequired truemet false

    Held-out evaluation speakers must never appear in training exports.

    evidence_required Published held-out speaker IDs never present in train splits

  • accra_ga_native_reviewrequired truemet false

    Native review must cover Accra Ga before any train export.

    evidence_required Paid Accra Ga native review records with trainingEligible fields

  • dangme_not_conflatedrequired truemet false

    Dangme is a separate language — never conflated with Gã training data.

    evidence_required Corpus metadata proving Dangme (ada) excluded from Ga train exports

  • rights_clear_for_exportrequired truemet false

    IP / commercial rights must clear before trainingEligible flips.

    evidence_required Legal memo clearing commercial vs research split for export corpus

Inference prefers matching person/org residency to nearby model hosting when ready — affinity, not a hard geo-fence. Accra (af-west-1) is the Ghana affinity target; live serving for verbalab + lugemi-ga is jnb today. No Accra GPU island is deployed. Ministry requests record X-Lugemi-Residency-Affinity soft pin.
