+## 2026-06-30 — Parseur iCalendar (T1) : contrat `Event` figé + ical.js vendoré
+

+`parserEvenements(flux, aujourdhui)` (`extension/evenements.js`), via **ical.js

+`{ uid, titre, description, lieu, debut: Date, fin: Date, categories: string[],
+journeeEntiere: boolean }`. Champs texte coercés en `""` si absents (l'aval
+suppose des chaînes). Le défaut « café » du lieu est appliqué **en aval**, pas
+ici.
+
+**Décisions tranchées :**
+- **`uid` seul, pas de `href`/`ETag`.** Le transport actuel (`?export`) renvoie
+  un ICS concaténé sans `href`/`ETag` par événement. L'`UID` est la clé stable ;
+  T2 résoudra l'adressage CalDAV par UID au moment du PUT. Le contrat n'est pas
+  alourdi.
+- **`journeeEntiere` dès T1** (drapeau porté, comportement « heure exigée »

+# Solution : [T1] Parser les événements iCalendar (version minimale)
+
+## Problème résolu
+Transformer le flux iCalendar **brut** (déjà récupéré par `nextcloud.js` en T1
+précédente) en une liste d'objets `Event` exploitables par tout l'aval de
+l'extension (liste, pré-remplissage du formulaire mairie, statut CalDAV en T2).
+
+Enjeu central : **cette tâche FIGE la forme de l'objet `Event`**. Le coût d'un
+mauvais contrat n'est pas dans T1, il est dans la refonte de la liste + du form +
+du statut le jour où T3 voudra ajouter la robustesse. La **forme prime sur le
+choix du parseur**.
+
+Frontière T1 tenue : on parse, on dédoublonne, on filtre le futur, on lit
+`CATEGORIES`. La robustesse (expansion `RRULE`, heure exigée pour les journées
+entières, durcissement des entrées dégénérées) est **différée à T3**, « traitée
+au plus simple » et **documentée**.
+
+## Approche choisie
+**Approche 3 du brainstorm** : `ical.js` (Mozilla) **vendoré en `.js`** + forme
+`Event` figée qui **anticipe T3** en portant dès maintenant le drapeau
+`journeeEntiere`. T1 *remplit* le contrat ; le *comportement* des cas limites
+reste différé.
+
+Pourquoi pas les alternatives :
+- **Parseur maison (regex)** : iCalendar est piégeux (line-folding à 75 octets,
+  échappements `\,` `\n` `\;`, `TZID`, `VALUE=DATE`). Le réinventer = dette, et
+  T3 (RRULE, fuseaux) deviendrait un enfer maison. `RECHERCHE.md` le déconseille
+  explicitement.
+- **`ical.js` + forme minimale stricte (approche 2)** : la forme n'exprimerait
+  pas la journée entière → T3 devrait **rouvrir le contrat figé**, exactement le
+  coût que T1 doit éviter. L'ajout d'un seul booléen rend le contrat durable pour
+  un coût marginal.
+
+Contrainte structurante respectée : **pas de build, pas de runtime**. `ical.js`
+v2.2.1 est vendoré tel quel (build ESM, export *default* = namespace `ICAL`),
+importé par une page propre de l'extension (`type=module`) — donc aucun
+changement de `manifest.json` (pas de `web_accessible_resources`).
+
+## Décisions clés
+- **Contrat `Event` figé** (ne PAS rouvrir sans accord) :
+  `{ uid, titre, description, lieu, debut: Date, fin: Date, categories: string[],
+  journeeEntiere: boolean }`. Champs texte coercés en `""` si absents (l'aval
+  suppose des chaînes, jamais `null`). Le défaut « café » du lieu est appliqué
+  **en aval**, pas dans le parseur.
+- **`uid` seul, pas de `href`/`ETag`.** Le transport actuel (`?export`) renvoie
+  un ICS concaténé sans `href`/`ETag` par événement. L'`UID` est la clé stable ;
+  T2 résoudra l'adressage CalDAV par UID au moment du PUT. Le contrat n'est pas
+  alourdi d'une préoccupation de transport.
+- **Fonction pure à dépendance injectée** : `parserEvenements(flux, aujourdhui)`.
+  `aujourdhui` est **obligatoire** (pas de défaut) → tests déterministes du
+  filtre futur. Convention du repo « params obligatoires par défaut ».
+- **Enregistrement des VTIMEZONE embarqués** avant toute conversion de date —
+  **non négociable** : sans lui, `toJSDate()` calcule un mauvais offset pour les
+  `TZID` non standards (prouvé par le test Africa/Lagos vs Europe/Paris).
+- **Passer par `ICAL.Event`** (pas lire `DTEND` en brut) : il dérive `endDate`
+  depuis `DURATION` ou `DTSTART` quand `DTEND` est absent, et expose `startDate.isDate`
+  pour la journée entière.
+- **Cas limites « au plus simple », différés à T3** : pas d'expansion `RRULE`
+  (récurrents pris au `DTSTART` maître + filtre futur → un récurrent au maître
+  **passé** disparaît, **trou assumé et documenté**) ; exceptions d'occurrence
+  (`RECURRENCE-ID`) ignorées via `isRecurrenceException()` ; journées entières au
+  minuit local.
+- **Tri & message « 0 événement futur » hors parseur** : le parseur renvoie les
+  événements **dans l'ordre du flux**, non triés (responsabilité de la liste).
+- **Périmètre : parseur NON câblé en prod en T1.** `liste.js` reste sur
+  `compterEvenements` (preuve de vie). Le câblage UI appartient à la tâche
+  d'affichage — éviter un demi-câblage jetable et un changement d'UX silencieux.
+  Conséquence : changement **purement additif**, rollback trivial.
+
+## Patterns à réutiliser
+**Enregistrement des fuseaux embarqués avant conversion de dates** (le piège
+n°1 du parsing iCalendar multi-fuseaux) :
+```js
+composant.getAllSubcomponents("vtimezone").forEach((vt) => {
+  const tzid = vt.getFirstPropertyValue("tzid");
+  if (tzid && !ICAL.TimezoneService.has(tzid)) {
+    ICAL.TimezoneService.register(vt); // idempotent (garde !has)
+  }
+});
+```
+
+**Dédup par UID en un seul passage O(n), maître conservé** :
+```js
+const parUid = new Map();
+for (const vevent of composant.getAllSubcomponents("vevent")) {
+  const ev = new ICAL.Event(vevent);
+  if (ev.isRecurrenceException()) continue; // RECURRENCE-ID non développés en T1
+  if (parUid.has(ev.uid)) continue;          // garde le premier rencontré
+  parUid.set(ev.uid, toEvent(ev, vevent));
+}
+```
+
+**Mapping robuste via `ICAL.Event`** (coercition `null → ""`, `endDate` dérivé) :
+```js
+{
+  uid: ev.uid,
+  titre: ev.summary ?? "",
+  description: ev.description ?? "",
+  lieu: ev.location ?? "",
+  debut: ev.startDate.toJSDate(),
+  fin: ev.endDate.toJSDate(),          // gère DTEND absent / DURATION
+  journeeEntiere: ev.startDate.isDate === true,
+}
+```
+
+**Lecture `CATEGORIES` tolérante aux deux formes** (valeurs séparées par virgule
+ET/OU propriétés répétées) :
+```js
+vevent.getAllProperties("categories").flatMap((prop) => prop.getValues());
+```
+
+**Filtre futur inclusif au minuit local** (aujourd'hui inclus) :
+```js
+const seuil = new Date(aujourdhui); seuil.setHours(0, 0, 0, 0);
+return [...parUid.values()].filter((e) => e.debut.getTime() >= seuil.getTime());
+```
+
+**Tests Bun avec fixtures ICS inline** (jamais l'export réel = données perso des
+bénévoles) : helpers `vcalendar(...)` / `vevent(...)` qui joignent les lignes en
+`\r\n` (CRLF de la RFC 5545), `aujourdhui` figé pour le déterminisme. Un
+`VTIMEZONE` Paris et un Lagos inline prouvent l'enregistrement des fuseaux.
+
+## Pièges à éviter
+- **VTIMEZONE non enregistré → offset faux.** Le piège central : `toJSDate()`
+  produit silencieusement une mauvaise heure. Toujours enregistrer les VTIMEZONE
+  embarqués avant conversion. Couvert par le test Africa/Lagos (UTC+1) ≠
+  Europe/Paris (UTC+2 l'été).
+- **Lire `DTEND` en brut** : il est souvent absent. Passer par
+  `ICAL.Event.endDate` qui le dérive (durée / start), sinon plantage.
+- **`summary`/`description`/`location` peuvent renvoyer `null`** : toujours
+  coercer en `""` — l'aval (form, liste) suppose des chaînes.
+- **Récurrents au DTSTART maître passé disparaissent** (pas d'expansion RRULE en
+  T1). **Trou produit assumé et documenté**, comblé en T3. Or les récurrents
+  (atelier hebdo, permanence) sont souvent ceux qu'on veut publier → priorité T3.
+- **Pureté nuancée par un état global** (signalé P3 en review) :
+  `TimezoneService.register` mute un registre **global** partagé. Idempotent et
+  bénin, mais si deux flux portent le même `TZID` avec des définitions
+  différentes, **la première enregistrée gagne** pour la session. Le commentaire
+  le note ; ne pas qualifier la fonction de « pure » sans nuance.
+- **Entrées dégénérées non durcies en T1** (constats Inzaghi, hors périmètre,
+  pas des anomalies) : flux chaîne vide `""` ou non-ICS → `ICAL.parse` lève ;
+  VEVENT sans `DTSTART` → lève ; VEVENT sans `UID` → clé `null` (collision). Le
+  transport renvoie toujours un VCALENDAR valide ; à durcir en T3 si besoin.
+- **Ne pas committer l'export réel du calendrier** : données personnelles des
+  bénévoles. Fixtures inline uniquement.
+- **Ne pas câbler le parseur dans `liste.js` en T1** : tentation de « finir le
+  travail », mais le rendu des cartes appartient à la tâche d'affichage. Un
+  demi-câblage serait jetable et changerait l'UX en douce.

+2. License Grants and Conditions
+--------------------------------
+
+2.1. Grants
+
+Each Contributor hereby grants You a world-wide, royalty-free,
+non-exclusive license:
+
+(a) under intellectual property rights (other than patent or trademark)
+    Licensable by such Contributor to use, reproduce, make available,
+    modify, display, perform, distribute, and otherwise exploit its
+    Contributions, either on an unmodified basis, with Modifications, or
+    as part of a Larger Work; and
+
+(b) under Patent Claims of such Contributor to make, use, sell, offer
+    for sale, have made, import, and otherwise transfer either its
+    Contributions or its Contributor Version.
+
+2.2. Effective Date
+
+The licenses granted in Section 2.1 with respect to any Contribution
+become effective for each Contribution on the date the Contributor first
+distributes such Contribution.
+
+2.3. Limitations on Grant Scope
+
+The licenses granted in this Section 2 are the only rights granted under
+this License. No additional rights or licenses will be implied from the
+distribution or licensing of Covered Software under this License.
+Notwithstanding Section 2.1(b) above, no patent license is granted by a
+Contributor:
+
+(a) for any code that a Contributor has removed from Covered Software;
+    or
+
+(b) for infringements caused by: (i) Your and any other third party's
+    modifications of Covered Software, or (ii) the combination of its
+    Contributions with other software (except as part of its Contributor
+    Version); or
+
+(c) under Patent Claims infringed by Covered Software in the absence of
+    its Contributions.
+
+This License does not grant any rights in the trademarks, service marks,
+or logos of any Contributor (except as may be necessary to comply with
+the notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+No Contributor makes additional grants as a result of Your choice to
+distribute the Covered Software under a subsequent version of this
+License (see Section 10.2) or under the terms of a Secondary License (if
+permitted under the terms of Section 3.3).
+
+2.5. Representation
+
+Each Contributor represents that the Contributor believes its
+Contributions are its original creation(s) or it has sufficient rights
+to grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+This License is not intended to limit any rights You have under
+applicable copyright doctrines of fair use, fair dealing, or other
+equivalents.
+
+2.7. Conditions
+
+Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
+in Section 2.1.
+
+3. Responsibilities
+-------------------
+
+3.1. Distribution of Source Form
+
+All distribution of Covered Software in Source Code Form, including any
+Modifications that You create or to which You contribute, must be under
+the terms of this License. You must inform recipients that the Source
+Code Form of the Covered Software is governed by the terms of this
+License, and how they can obtain a copy of this License. You may not
+attempt to alter or restrict the recipients' rights in the Source Code
+Form.
+
+3.2. Distribution of Executable Form
+
+If You distribute Covered Software in Executable Form then:
+
+(a) such Covered Software must also be made available in Source Code
+    Form, as described in Section 3.1, and You must inform recipients of
+    the Executable Form how they can obtain a copy of such Source Code
+    Form by reasonable means in a timely manner, at a charge no more
+    than the cost of distribution to the recipient; and
+
+(b) You may distribute such Executable Form under the terms of this
+    License, or sublicense it under different terms, provided that the
+    license for the Executable Form does not attempt to limit or alter
+    the recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+You may create and distribute a Larger Work under terms of Your choice,
+provided that You also comply with the requirements of this License for
+the Covered Software. If the Larger Work is a combination of Covered
+Software with a work governed by one or more Secondary Licenses, and the
+Covered Software is not Incompatible With Secondary Licenses, this
+License permits You to additionally distribute such Covered Software
+under the terms of such Secondary License(s), so that the recipient of
+the Larger Work may, at their option, further distribute the Covered
+Software under the terms of either this License or such Secondary
+License(s).
+
+3.4. Notices
+
+You may not remove or alter the substance of any license notices
+(including copyright notices, patent notices, disclaimers of warranty,
+or limitations of liability) contained within the Source Code Form of
+the Covered Software, except that You may alter any license notices to
+the extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+You may choose to offer, and to charge a fee for, warranty, support,
+indemnity or liability obligations to one or more recipients of Covered
+Software. However, You may do so only on Your own behalf, and not on
+behalf of any Contributor. You must make it absolutely clear that any
+such warranty, support, indemnity, or liability obligation is offered by
+You alone, and You hereby agree to indemnify every Contributor for any
+liability incurred by such Contributor as a result of warranty, support,
+indemnity or liability terms You offer. You may include additional
+disclaimers of warranty and limitations of liability specific to any
+jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+---------------------------------------------------
+
+If it is impossible for You to comply with any of the terms of this
+License with respect to some or all of the Covered Software due to
+statute, judicial order, or regulation then You must: (a) comply with
+the terms of this License to the maximum extent possible; and (b)
+describe the limitations and the code they affect. Such description must
+be placed in a text file included with all distributions of the Covered
+Software under this License. Except to the extent prohibited by statute
+or regulation, such description must be sufficiently detailed for a
+recipient of ordinary skill to be able to understand it.
+
+5. Termination
+--------------
+
+5.1. The rights granted under this License will terminate automatically
+if You fail to comply with any of its terms. However, if You become
+compliant, then the rights granted under this License from a particular
+Contributor are reinstated (a) provisionally, unless and until such
+Contributor explicitly and finally terminates Your grants, and (b) on an
+ongoing basis, if such Contributor fails to notify You of the
+non-compliance by some reasonable means prior to 60 days after You have
+come back into compliance. Moreover, Your grants from a particular
+Contributor are reinstated on an ongoing basis if such Contributor
+notifies You of the non-compliance by some reasonable means, this is the
+first time You have received notice of non-compliance with this License
+from such Contributor, and You become compliant prior to 30 days after
+Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+infringement claim (excluding declaratory judgment actions,
+counter-claims, and cross-claims) alleging that a Contributor Version
+directly or indirectly infringes any patent, then the rights granted to
+You by any and all Contributors for the Covered Software under Section
+2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all
+end user license agreements (excluding distributors and resellers) which
+have been validly granted by You or Your distributors under this License
+prior to termination shall survive termination.

+*  Covered Software is provided under this License on an "as is"       *
+*  basis, without warranty of any kind, either expressed, implied, or  *
+*  statutory, including, without limitation, warranties that the       *
+*  Covered Software is free of defects, merchantable, fit for a        *
+*  particular purpose or non-infringing. The entire risk as to the     *
+*  quality and performance of the Covered Software is with You.        *
+*  Should any Covered Software prove defective in any respect, You     *
+*  (not any Contributor) assume the cost of any necessary servicing,   *
+*  repair, or correction. This disclaimer of warranty constitutes an   *
+*  essential part of this License. No use of any Covered Software is   *
+*  authorized under this License except under this disclaimer.         *
+*                                                                      *

+*  Under no circumstances and under no legal theory, whether tort      *
+*  (including negligence), contract, or otherwise, shall any           *
+*  Contributor, or anyone who distributes Covered Software as          *
+*  permitted above, be liable to You for any direct, indirect,         *
+*  special, incidental, or consequential damages of any character      *
+*  including, without limitation, damages for lost profits, loss of    *
+*  goodwill, work stoppage, computer failure or malfunction, or any    *

+*  personal injury resulting from such party's negligence to the       *
+*  extent applicable law prohibits such limitation. Some               *
+*  jurisdictions do not allow the exclusion or limitation of           *
+*  incidental or consequential damages, so this exclusion and          *
+*  limitation may not apply to You.                                    *

+
+8. Litigation
+-------------
+
+Any litigation relating to this License may be brought only in the
+courts of a jurisdiction where the defendant maintains its principal
+place of business and such litigation shall be governed by laws of that
+jurisdiction, without reference to its conflict-of-law provisions.
+Nothing in this Section shall prevent a party's ability to bring
+cross-claims or counter-claims.
+
+9. Miscellaneous
+----------------
+
+This License represents the complete agreement concerning the subject
+matter hereof. If any provision of this License is held to be
+unenforceable, such provision shall be reformed only to the extent
+necessary to make it enforceable. Any law or regulation which provides
+that the language of a contract shall be construed against the drafter
+shall not be used to construe this License against a Contributor.
+
+10. Versions of the License
+---------------------------
+
+10.1. New Versions
+
+Mozilla Foundation is the license steward. Except as provided in Section
+10.3, no one other than the license steward has the right to modify or

+10.2. Effect of New Versions
+
+You may distribute the Covered Software under the terms of the version
+of the License under which You originally received the Covered Software,
+or under the terms of any subsequent version published by the license
+steward.
+
+10.3. Modified Versions
+
+If you create software not governed by this License, and you want to
+create a new license for such software, you may create and use a
+modified version of this License if you rename the license and remove
+any references to the name of the license steward (except to note that
+such modified license differs from this License).
+
+10.4. Distributing Source Code Form that is Incompatible With Secondary
+Licenses
