+risquer de vider une vraie base de dev locale, `NODE_ENV=test` (posé par le
+script `test`) fait charger `apps/api/.env.test` au lieu de `.env` — un
+fichier **à créer toi-même**, pas fourni automatiquement :
 
-- `apps/api/features/*.feature` — scénarios en Given/When/Then (`health.feature` sert
-  d'exemple)
-- `apps/api/features/step-definitions/*.steps.ts` — implémentation des steps

-  scénario (instancie l'app Express in-process via `createApp()`, comme le fait déjà
-  supertest côté Mocha — pas besoin de lancer un vrai serveur)

-  TypeScript/ESM ci-dessous)

+# puis édite-le : mêmes identifiants Postgres que ton .env, mais une base
+# différente (ex. batchcooking_test) — .env.test.example documente les
+# commandes exactes pour la créer et lui appliquer le schéma.
+```
 
-Pour ajouter un scénario : écrire le `.feature`, lancer `pnpm --filter api test:bdd`,
-implémenter les steps manquants (Cucumber affiche des snippets tout prêts pour ceux
-qui n'existent pas encore).
+Un garde-fou (`assertRunningAgainstTestDatabase()`) refuse d'exécuter
+`resetDatabase()` si `DATABASE_URL` ne contient ni `"test"` ni `"ci"` — la
+seule base qu'il doit rejeter est ta vraie base de dev.
 
-> **Piège TypeScript/ESM à connaître** (déjà rencontré avec `cypress.config.ts`) :
-> les fichiers de config d'outils tiers qui font du chargement dynamique de TS
-> (`cucumber.cjs`, `cypress.config.ts`…) sont sensibles au `"type": "module"` du
-> `package.json`. `cucumber.cjs` évite le problème *pour sa propre config* en étant
-> explicitement CommonJS ; les steps/world restent en `.ts` ESM classique et sont
-> chargés via `tsx` (`NODE_OPTIONS=--import=tsx`, voir le script `test:bdd`).
+`services/tech-step-intent-service` doit aussi tourner en local avant
+`pnpm --filter api test` — les tests touchant `tech-step-matcher.ts` passent
+par le vrai service (jamais un mock, voir
+[specs/dev-conventions.md](specs/dev-conventions.md)) et échouent avec une
+erreur de connexion, pas une assertion utile, s'il n'est pas démarré. Voir la

+ * phrase wins, same "specificity resolves overlaps" idea as

+ *
+ * 1. **NER** (the intent service's `PhraseMatcher`, built from its own

+ *    mention in the whole description, each with its exact character span —
+ *    mechanically the same job the old regexes did, just as flat synonym
+ *    lists instead of hand-written patterns. This step alone is *not* the
+ *    final answer — see step 3.
+ * 2. The description is cut into clauses around those candidate spans
+ *    ({@link splitIntoClauses}) — a step naming two techniques ("Dans une
+ *    poêle chaude, faire chauffer une noix de beurre" is both `preheat`
+ *    and `melt`) needs each judged on its own surrounding context, not the
+ *    whole step lumped into one classification.
+ * 3. **NLP intent classification** (the intent service's `textcat`, trained
+ *    on its own `training_data.py`'s `utterances`) then classifies each
+ *    clause on its own — this is what actually delivers "meaning, not
+ *    keywords": the classifier was deliberately trained on paraphrases that
+ *    never use the technique's own verb (e.g. "jusqu'à ce que le beurre ait
+ *    disparu" for `melt`), so a clause reaching it gets labeled by what it
+ *    was trained to recognize as *meaning* a technique, not by which
+ *    literal word the NER step happened to anchor on. The NER-implied
+ *    technique is kept only as a fallback for a clause the classifier
+ *    isn't confident about (see `CONFIDENCE_THRESHOLD`) — a clearly
+ *    keyword-anchored clause a small model merely isn't sure how to
+ *    classify shouldn't be dropped outright.
+ *
+ * A single instruction can genuinely involve more than one technique — see
+ * point 2 above — so `matchTechSteps`/`matchTechStepSpans` both return the
+ * whole *ordered sequence* they find, not a single winner, matching
+ * `Step.techSteps` (schema.prisma's `StepTechStep`, an ordered join table).
+ *

+ *      (informed by `list-pending-training-suggestions.ts`'s report),
+ *      decided which `TechStepTrainingSuggestion` ids they incorporated
+ *      (`--applied=`) or explicitly discarded (`--rejected=`), **and
+ *      restarted `tech-step-intent-service`** so it retrains from the
+ *      edited corpus — that service only ever trains once, at its own
+ *      startup (see its README), so this script's eval gate below is
+ *      meaningless against a service still running the old corpus.
+ *   2. This script re-runs the F1 regression gate
+ *      ({@link runTechStepEvalSuite} against {@link MIN_OVERALL_F1}) —
+ *      refuses to backfill at all if the edited corpus scores worse than
+ *      the floor, so a bad edit never reaches every existing recipe.
+ *   3. Backfills every `Step`'s `StepTechStep` sequence against the new
+ *      corpus ({@link backfillTechSteps}).
+ *   4. Marks the given suggestion ids `applied`/`rejected`, so
+ *      `list-pending-training-suggestions.ts`'s next report doesn't
+ *      surface them again.
+ *
+ * Usage:
+ *
+ *   pnpm --filter api exec tsx src/scripts/retrain-tech-steps.ts --applied=12,13 --rejected=14
+ *
+ * `--applied`/`--rejected` are both optional — omitting both still runs
+ * the gate + backfill, just leaves every suggestion's `status` untouched
+ * (useful for re-running the backfill alone after a corpus edit made with
