Contacts & address books

Summary

RN covers the visible surface reasonably well (list with alphabetical index, detail screen with every RFC 9553 field block, a full edit form, groups with member management, address-book CRUD, vCard import/export, trusted-senders book, contact activity). The gaps are mostly below the UI: the RN JMAP layer (src/api/contacts.ts) ignores notCreated/notUpdated/notDestroyed, never assigns a UID (#644), does not re-fetch the created card (so a freshly saved contact shows as a blank row), does not paginate ContactCard/query, and has no first-touch gate (#907). The RN vCard parser is a stale fork of the web one: it predates #224 (dates are imported as raw strings, which Stalwart drops), lacks every X- vendor extension, Apple grouped labels, and org-only cards (#701). Composer autocomplete is contacts-only (no groups, no recent recipients, no directory), there is no "add sender to contacts" entry point from the viewer, no way to create a group, no shared/group-account address books, and the trusted-senders settings screen cannot show or remove entries that live in the synced book.

Findings

JMAP / store layer

• Newly created contact appears as a blank row until refresh — P2 — bug — fixed in 580e010

  • What WEB does: client.createContact reads the server-assigned id from created and then re-fetches the full card with ContactCard/get before returning it (lib/jmap/client.ts:5128-5133), so the store appends a complete card.
  • What RN does: createContact returns res.methodResponses[0][1].created['new-contact'] verbatim (src/api/contacts.ts:73) which per JMAP only carries server-set properties (id, created, updated…); the store appends that stub (src/stores/contacts-store.ts:170-174). ContactFormScreen.handleSave just goBack()s (src/screens/ContactFormScreen.tsx:631-633) so the list shows an "Unnamed" row with no email until a push/pull refresh; doDuplicate even navigates to that stub (src/screens/ContactDetailScreen.tsx:231-232).
  • Fix hint: in api/contacts.ts merge { ...contact, addressBookIds, ...created } or issue a follow-up ContactCard/get for the created id (mirror WEB) before returning.

• ContactCard/set errors are swallowed or crash with a TypeError — P2 — bug — fixed in 580e010

  • What WEB does: every set call checks notCreated / notUpdated / notDestroyed and throws the server description (lib/jmap/client.ts:5122-5126, 5155-5160, 5180-5184); the method-level error response is also handled.
  • What RN does: createContact indexes .created['new-contact'] without checking created/notCreated (src/api/contacts.ts:73) so a rejected card surfaces as "Cannot read property 'new-contact' of undefined"; updateContact (:76-85) and deleteContacts (:87-93) never look at notUpdated/notDestroyed, so the store applies the optimistic change (src/stores/contacts-store.ts:176-195) although the server refused it (e.g. read-only shared book, invalid PartialDate).
  • Fix hint: route all three through methodResult() (already defined at src/api/contacts.ts:7-15) and throw on notCreated/notUpdated/notDestroyed[id].description; bulkDelete should only drop the ids that were actually destroyed.

• No UID assigned on contact creation (#644) — P2 — bugfix-parity — fixed in 580e010

  • What WEB does: sends uid: contactData.uid || 'urn:uuid:<uuid>' on every create because Stalwart stores the card without one otherwise (lib/jmap/client.ts:5113-5116, changelog 1.6.x "Assign a UID to contact cards on creation").
  • What RN does: createContact forwards the card as-is (src/api/contacts.ts:65-70); form, import, duplicate and trusted-sender creation all go through it. Group membership then falls back to the raw id (src/screens/GroupDetailScreen.tsx:90), and exported vCards/CardDAV clients get UID-less cards.
  • Fix hint: add uid: contact.uid || \urn:uuid:${generateUUID()}`inapi/contacts.ts createContact(RN already hassrc/lib/uuid.ts`).

• Contact list silently truncated at the query limit (no pagination) — P2 — bug — fixed in 580e010

  • What WEB does: fetchPaginatedContacts walks ContactCard/query with position/limit = maxObjectsInGet until total is reached, then batches ContactCard/get (lib/jmap/client.ts:~4985-5022).
  • What RN does: a single ContactCard/query with limit: 1000 (src/api/contacts.ts:26-40); the server may clamp the limit lower and anything beyond is never fetched. getContacts batches the get correctly (:42-57).
  • Fix hint: loop on position until ids.length < limit || total reached in queryContacts, mirroring WEB.

• No first-touch gate: concurrent AddressBook/get + ContactCard/query on cold start (#907) — P2 — bugfix-parity — fixed in 26a34d5

  • Store-side: fetchAddressBooks/fetchContacts are single-flight and contacts wait for an in-flight AddressBook/get; the request-level FirstTouchGate in src/api/jmap-client.ts was added by the client agent.
  • What WEB does: FirstTouchGate serialises the first request per (collection, account) so Stalwart's lazy default-collection creation cannot race across cluster nodes (lib/jmap/first-touch-gate.ts:1-101, wired at lib/jmap/client.ts:678,1129; changelog 1.9.x "Gate first-touch calendar and contacts requests to stop duplicate default calendars (#907)").
  • What RN does: ContactsScreen fires fetchAddressBooks() and fetchContacts() in the same effect (src/screens/ContactsScreen.tsx:120-123) and restoreSession fans out fetchContacts + fetchCalendars (src/stores/auth-store.ts:91-93) with no gate in src/api/jmap-client.ts (grep for gate/firstTouch: none). Against a multi-node Stalwart this can mint a duplicate default address book / calendar.
  • Fix hint: port first-touch-gate.ts into src/api/ and wrap jmapClient.request (key on AddressBook/, ContactCard/, Calendar/, CalendarEvent/ + accountId); reset it on logout/account switch.

• Contacts account id: RN uses the mail primary account, not primaryAccounts[contacts] — P3 — partial — fixed in 580e010

  • What WEB does: getContactsAccountId() prefers primaryAccounts["urn:ietf:params:jmap:contacts"] (lib/jmap/client.ts:4677-4680).
  • What RN does: every call uses jmapClient.accountId, resolved from the mail/core primary (src/api/contacts.ts:18,32,44,63; src/api/jmap-client.ts:388-399).
  • Fix hint: add getContactsAccountId() to the RN client and use it in api/contacts.ts.

• Shared / group-account address books not listed or writable — P2 — missing — fixed in 26a34d5

  • Drawer "Shared from X" sections in 358bdb9; writes are routed to the owning account via originalId/accountId.
  • What WEB does: getAllAddressBooks/getAllContacts iterate every contacts-capable or non-personal account, namespace ids as accountId:bookId, tag isShared/accountName (lib/jmap/client.ts:4718-4733, 4756-4793, 5036-5070); sidebar renders "Shared from X" sections (components/contacts/contacts-sidebar.tsx:160-176, 562-603); create/update/move de-namespace ids and pick the right account (stores/contact-store.ts:473-527, 529-561, 926-978); changelog 1.8.x "Require an explicit shared-account fallback for contacts and calendars".
  • What RN does: single-account only (src/api/contacts.ts throughout); AddressBook type has no accountId/isShared (src/api/types.ts:369-377).
  • Fix hint: iterate session.accounts where accountCapabilities[contacts] or !isPersonal (as WEB getContactCapableAccountIds), namespace ids, and render a "Shared from" section in ContactsSidebarDrawer; route writes to the owning account. The myRights.mayWrite checks already present in AddressBookPickerSheet:96 and ContactsSettings:204,209 will then become meaningful.

• Deleting a contact does not clean group member references locally — P3 — partial — fixed in 26a34d5

  • Drawer member counts resolve through selectGroupMembers in 358bdb9.
  • What WEB does: cleanGroupMembers strips the deleted card's id/uid/urn:uuid: variants from every group's members in state on delete/bulk delete (stores/contact-store.ts:339-366, 571-578, 911-918).
  • What RN does: deleteContact/bulkDelete just filter the list (src/stores/contacts-store.ts:185-195); group counts in the drawer use raw Object.keys(g.members).length (src/components/contacts/ContactsSidebarDrawer.tsx:150) so they keep counting deleted members until the next full refresh.
  • Fix hint: port cleanGroupMembers; resolve drawer counts through selectGroupMembers like WEB memberCountByGroup (contacts-sidebar.tsx:250-270).

• Deleting an address book leaves its contacts in the cache — P3 — partial — fixed in 26a34d5

  • What WEB does: removeAddressBook drops contacts filed in that book from state (stores/contact-store.ts:1053-1056).
  • What RN does: strips the book id but keeps the cards (src/stores/contacts-store.ts:260-276), so they show under "All"/"Uncategorized" until a refresh; the confirm text ("will be removed from this book") also implies they survive (src/components/settings/ContactsSettings.tsx:282).
  • Fix hint: filter out cards whose only book was the deleted one, or call fetchContacts() after the destroy.

• Persisting every contact card (incl. base64 photos) to AsyncStorage — P3 — rn-only-bug — fixed in 26a34d5

  • media is stripped from the persisted snapshot; picked photos are downscaled to 512px JPEG with expo-image-manipulator in 9800ad0.
  • What RN does: partialize persists contacts and addressBooks (src/stores/contacts-store.ts:355-366); cards carry inline data: photos (src/screens/ContactFormScreen.tsx:690-691 stores the picked image as base64 with no downscale). Android AsyncStorage's default 6 MB cap will make the write fail for a few hundred photo contacts and the cache silently stops updating.
  • Fix hint: strip media from the persisted snapshot (re-hydrate photos from the server) and/or downscale photos on pick (WEB caps at 512px JPEG q0.85, components/contacts/contact-form.tsx:96-126).

Address books

• Set default address book missing — P3 — missing — fixed in bc4c57e

  • setDefaultAddressBook (onSuccessSetIsDefault) and the isDefault-free update patch landed in 580e010; new contacts/imports prefer the default book via getDefaultAddressBookId.
  • What WEB does: context-menu "Set as default" uses AddressBook/set onSuccessSetIsDefault (components/contacts/contacts-sidebar.tsx:612-663, lib/jmap/client.ts:4851-4869, stores/contact-store.ts:1017-1044), and the create form preselects the default book (components/contacts/contact-form.tsx:362-367).
  • What RN does: no UI; updateAddressBook even forwards isDefault as a patch property (src/api/contacts.ts:117,122) which WEB notes is read-only and fails the whole update (lib/jmap/client.ts:4819-4821). New contacts/imports default to addressBooks[0] (src/screens/ContactFormScreen.tsx:581,591-593; src/screens/ContactsScreen.tsx:201-204; src/components/settings/ContactsSettings.tsx:54).
  • Fix hint: add setDefaultAddressBook (onSuccessSetIsDefault) to api/contacts.ts + a row action in ContactsSettings; drop isDefault from the update patch; prefer books.find(b => b.isDefault) as the default target.

• Default address book can be offered for deletion — P3 — partial — fixed in bc4c57e

  • What WEB does: hides delete for isDefault/shared books (components/contacts/contacts-sidebar.tsx:615).
  • What RN does: shows the trash icon whenever books.length > 1 && mayDelete !== false (src/components/settings/ContactsSettings.tsx:209); the server then rejects and the user sees a raw error.
  • Fix hint: add !book.isDefault to the guard.

• Address book share / visibility (subscription) management missing — P3 — missing

  • deferred: shareWith/myRights are now requested explicitly (580e010) and typed on AddressBook; no sharing sheet on mobile yet (reuse the calendar-sharing sheet when it exists).
  • What WEB does: shareAddressBook via shareWith/<principal> patch + ShareCollectionDialog (stores/contact-store.ts:1064-1085, components/contacts/contacts-app.tsx:1142-1158); sidebar shows a shared indicator (contacts-sidebar.tsx:879-881).
  • What RN does: nothing; getAddressBooks requests no properties so shareWith is whatever the server defaults to (src/api/contacts.ts:17-24; WEB requests ADDRESS_BOOK_PROPERTIES incl. shareWith, lib/jmap/client.ts:252-261, #257).
  • Fix hint: low priority on mobile; if added, reuse whatever calendar-sharing sheet the calendar agent proposes and request properties explicitly.

Contact card / form

• Clearing a whole field group on edit never reaches the server — P2 — rn-only-bug — fixed in 9800ad0

  • What RN does: formToPatch only includes keys that are non-empty (src/screens/ContactFormScreen.tsx:378-395), and updateContact sends the patch as a JMAP update (src/api/contacts.ts:82). Removing the last phone/address/note/keyword/anniversary/online link of an existing contact therefore omits the key, which JMAP treats as "unchanged"; the store merge (contacts-store.ts:178-182) also keeps the old value, so the UI shows the removed items again.
  • Fix hint: in edit mode emit null for every collection the form owns that ended up empty (emails, phones, addresses, organizations, titles, anniversaries, onlineServices, personalInfo, notes, keywords, nicknames, speakToAs, calendarUri…) — the same approach WEB uses for media: null (components/contacts/contact-form.tsx:555-558).

• Saving the form drops non-photo media (logo, sound) — P3 — rn-only-bug — fixed in 9800ad0

  • What WEB does: copies every non-photo media entry through and keeps the original photo key (components/contacts/contact-form.tsx:544-553).
  • What RN does: rebuilds media with only media.photo (src/screens/ContactFormScreen.tsx:359-366,395), so an imported LOGO/SOUND is deleted on the first edit.
  • Fix hint: carry existing.media entries with kind !== 'photo' into the patch.

• Anniversary input accepts free text that the server rejects; year-only dates get a fake Jan 1 — P2 — rn-only-bug — fixed in 9800ad0

  • stringToPartialDate / lossless partialDateToString live in src/lib/contact-utils.ts (580e010).
  • What WEB does: <input type="date"> plus stringToPartialDate always yields a structured PartialDate (components/contacts/contact-form.tsx:192-206, 525-528); changelog 1.9.x #224 stresses that Stalwart drops non-PartialDate anniversaries.
  • What RN does: stringToAnniversaryDate returns the raw string for anything other than YYYY-MM-DD / --MM-DD (src/screens/ContactFormScreen.tsx:116-128), so "1990-05", "May 5" or a YYYY-MM-DDT… value is sent as a string → Stalwart rejects the set (and, via the previous finding, the failure is invisible). partialDateToString pads a year-only or year-month PartialDate with 01 (:110), so merely opening and saving a contact with {year:1990} rewrites it to 1990-01-01 — this feeds the birthday calendar with a wrong day.
  • Fix hint: reject/normalise input to PartialDate (support YYYY, YYYY-MM, --MM-DD, ---DD like WEB parseVcardDate, lib/vcard.ts:360-394), and make partialDateToString lossless (1990, 1990-05).

• Organization-kind cards (#701) — P3 — partial — fixed in 9800ad0

  • Detail subtitle no longer repeats the org name (1cef53a).
  • What WEB does: person/organization toggle, org name validates as the identity, name.full filled from org, kind: 'org' written, detail hides the duplicated org line (components/contacts/contact-form.tsx:269-277, 443-449, 491-495, 560-563, 696-735; components/contacts/contact-detail.tsx:178-180).
  • What RN does: no toggle/kind; validation requires given/surname/full or an email (src/screens/ContactFormScreen.tsx:607-612), so an org card needs its name typed into "Display name" and an org-only card without email cannot be created; detail subtitle repeats the org under the heading when they are equal (src/screens/ContactDetailScreen.tsx:136).
  • Fix hint: add a Person/Organization pill in the Identity section; when org: skip name components, set name.full = org, kind: 'org', accept org name as identity; hide the equal subtitle.

• Photo data URIs from Stalwart not normalised (#307) — P2 — bugfix-parity — fixed in 580e010

  • What WEB does: normalizeContactPhotoUri rewrites data:base64,… / data:;base64,… to data:image/jpeg;base64,… in getContactPhotoUri and in the form (stores/contact-store.ts:157-180; contact-form.tsx:376).
  • What RN does: getContactPhotoUri returns media.uri raw (src/lib/contact-utils.ts:71-77), used by ContactListRow:38, ContactDetailScreen:114 and the form (ContactFormScreen.tsx:233-237); RN Image cannot decode a media-type-less data URI so such photos render blank, and re-saving writes the malformed URI back.
  • Fix hint: port normalizeContactPhotoUri into contact-utils.ts and apply in getContactPhotoUri + contactToForm.

• Picked photos are stored full-size — P3 — partial — fixed in 9800ad0

  • What WEB does: downscales to 512px JPEG before embedding (components/contacts/contact-form.tsx:96-126) and rejects files >10 MB.
  • What RN does: ImagePicker with quality: 0.8, no dimension cap, base64 straight into the card (src/screens/ContactFormScreen.tsx:680-695).
  • Fix hint: use expo-image-manipulator to resize to ≤512px before reading base64.

• Duplicate contact keeps the source UID — P2 — rn-only-bug — fixed in 1cef53a

  • What WEB does: strips id, uid, created, updated before creating the copy (components/contacts/contacts-app.tsx:448-451).
  • What RN does: doDuplicate only strips id/addressBookIds/created/updated (src/screens/ContactDetailScreen.tsx:216-222), so the copy is created with the same uid; group membership by uid then matches both cards and CardDAV/vCard consumers see two cards with one UID.
  • Fix hint: also drop uid (and let createContact mint a fresh one once the #644 fix lands).

• Gender vocabulary differs from WEB and from the vCard exporter — P3 — partial — fixed in 9800ad0

  • What WEB does: masculine | feminine | other | none | unknown (vCard SEX mapping, components/contacts/contact-form.tsx:1062-1069), which grammaticalGenderToVcardSex understands (lib/vcard.ts:34-48).
  • What RN does: masculine | feminine | common | neuter | animate | inanimate (src/screens/ContactFormScreen.tsx:437-445); values other than masculine/feminine export as an empty GENDER and display differently across clients.
  • Fix hint: align option lists (or accept both on display) so the same card renders the same value in both apps.

• Online service label and multiple nicknames not editable — P3 — partial — fixed in 9800ad0

  • Detail shows every nickname (1cef53a).
  • What WEB does: online-service entries carry label (contact-form.tsx:24-28, 517-523); detail shows all nicknames (contact-detail.tsx:194-196).
  • What RN does: OnlineDraft has only uri/service (src/screens/ContactFormScreen.tsx:42, 332-338), and the form/detail read only the first nickname (:168-170, 269-270; src/lib/contact-utils.ts:171-174). Saving a card with several nicknames collapses them to one.
  • Fix hint: keep unknown nicknames when rebuilding nicknames, add a label field to the online row.

• Display name includes the middle name (differs from WEB sorting/grouping) — P3 — partial — fixed in 580e010

  • What WEB does: given + surname only, then name.full, nickname, org, email (stores/contact-store.ts:125-150).
  • What RN does: given + middle + surname (src/lib/contact-utils.ts:13-14). Harmless on its own but sort order, dedupe keys and #672-style name sanitising diverge between clients.
  • Fix hint: drop middle from the join or make it a display-only concern.

List, search, sort

• Alphabetical index buckets every non-ASCII initial under "#" — P3 — bug — fixed in 358bdb9

  • What WEB does: \p{L} test + Intl.Collator(locale, sensitivity base) so Ä/É/Ł get their own sections (components/contacts/contact-list.tsx:242-262).
  • What RN does: /[A-Z]/.test(letter) (src/screens/ContactsScreen.tsx:53-54), so "Éric" and "Ölçer" land in "#".
  • Fix hint: use /\p{L}/u and localeCompare (Hermes supports Unicode property escapes).

• "Uncategorized" means "no address book" in RN but "no category" in WEB, and its count is hard-coded 0 — P3 — bug — fixed in 358bdb9

  • selectUncategorized (no keywords) in 26a34d5; the drawer row moved under Tags as "No category" with a live count.
  • What WEB does: "No category" = contacts without keywords, with a live count (components/contacts/contacts-sidebar.tsx:246-248, 526-541; contacts-app.tsx:283-285).
  • What RN does: filter = contacts with no addressBookIds (src/stores/contacts-store.ts:439-440; src/screens/ContactsScreen.tsx:146-149), drawer row passes count={0} (src/components/contacts/ContactsSidebarDrawer.tsx:128-136) so the count never shows; on Stalwart every card has a book so the view is always empty.
  • Fix hint: redefine as "no keywords", move the row under the Tags section, compute the count.

• Contact list filters (org / title / location / domain / birthday month / has email-phone-photo) missing — P3 — missing

  • deferred: optional; free-text search only.
  • What WEB does: filter drawer with tri-state chips (components/contacts/contact-list.tsx:18-76, 154-228, 350-456; changelog 1.5.x "Revamp contact detail view with filters").
  • What RN does: free-text search only (src/lib/contact-utils.ts:216-241).
  • Fix hint: optional; a filter sheet reusing the WEB predicate block would do.

• No select-all / bulk export in multi-select — P3 — partial — fixed in 358bdb9

  • What WEB does: select-all toggle, range select, bulk export, bulk add-to-group (components/contacts/contact-list.tsx:283-305, 458-502).
  • What RN does: long-press multi-select with delete / move / tag only (src/screens/ContactsScreen.tsx:164-226, 282-313).
  • Fix hint: add "Select all visible" and "Export selected" (reuse contactsToVCard + share flow from ContactsSettings:56-78).

• Rename category (keyword) missing — P3 — missing — fixed in 358bdb9

  • renameKeyword in the store (26a34d5); long-press a tag in the drawer to rename.
  • What WEB does: keyword context menu → rename, rewrites keywords on every affected card (components/contacts/contacts-sidebar.tsx:680-698; stores/contact-store.ts:1087-1116).
  • What RN does: tags can be assigned/removed per contact and in bulk (TagAssignSheet, contacts-store.ts:213-235) but not renamed.
  • Fix hint: long-press on a Tags row in ContactsSidebarDrawer → prompt → loop updateContact like WEB renameKeyword.

• Add-to-group from the contact itself missing — P3 — partial — fixed in 1cef53a

  • What WEB does: detail "More" menu and list context menu offer "Add to group" (creating a group if none) (components/contacts/contacts-app.tsx:438-446; contact-detail.tsx:150-152).
  • What RN does: membership is only editable from GroupDetailScreen (src/screens/GroupDetailScreen.tsx:86-98); the detail "More" sheet has Duplicate/Move/Export/Delete only (src/screens/ContactDetailScreen.tsx:247-270).
  • Fix hint: add a "Add to group" item that opens a group picker (list of selectGroups) and calls the same members patch as GroupDetailScreen.addMembers.

Groups

• No way to create a contact group — P2 — missing — fixed in 9800ad0

  • "New group" row in the drawer and long-press on the header "+" (358bdb9); createGroup/memberIds route param.
  • What WEB does: "+" menu → "Create group" with name + member picker (components/contacts/contacts-sidebar.tsx:299-305; contact-group-form.tsx; stores/contact-store.ts:734-760).
  • What RN does: ContactForm supports asGroup (src/screens/ContactFormScreen.tsx:554,627) but the only caller passes an existing contactId for editing (src/screens/GroupDetailScreen.tsx:138; grep asGroup in src/: no other call site). The Contacts header "+" always opens a plain new-contact form (src/screens/ContactsScreen.tsx:336-343).
  • Fix hint: add "New group" to the header/drawer that navigates to ContactForm { asGroup: true } with a members picker (ContactPickerSheet), or a dedicated small screen that creates { kind:'group', name:{components:[{kind:'given', value}]}, members }.

• Group edit reuses the full person form (name split into first/last, photo, emails…) — P3 — partial — fixed in 9800ad0

  • What WEB does: dedicated group form with name + searchable member checklist (components/contacts/contact-group-form.tsx:80-196).
  • What RN does: GroupDetailScreen → ContactForm asGroup shows Prefix/First/Middle/Last/Nickname, Email, Phone… (src/screens/ContactFormScreen.tsx:747-813); a group named "Sales Team" appears in "First name".
  • Fix hint: when asGroup, render a single "Group name" field bound to given and hide the person-only sections.

• Group compose: RN expands to individual recipients; no To/Cc/Bcc choice — P3 — partial — fixed in 1cef53a

  • Dedupe via getGroupRecipients (26a34d5); a single group chip is up to the composer agent.
  • What WEB does: hands the composer one expandable group chip (RFC 5322 group syntax) with a To/Cc/Bcc submenu (components/contacts/contacts-app.tsx:561-587; contact-group-detail.tsx:69-87; changelog 1.7.x "Contact groups as single expandable recipient chips").
  • What RN does: "Email all" pushes one recipient per member into prefillTo (src/screens/GroupDetailScreen.tsx:72-84). Functionally fine; dedupe by email is missing (two members sharing an address are both added).
  • Fix hint: dedupe case-insensitively; a group chip is optional unless the composer agent adds group chips.

Composer autocomplete

• Autocomplete lacks groups, recent recipients (Sent), on-demand server search and directory principals — P2 — missing
  • store-side done in 26a34d5 (getAutocomplete with group entries + recent recipients, loadRecentRecipients/searchRecipients fed by src/api/recent-recipients.ts, getGroupRecipients, #672 normalisation); the composer uses getAutocomplete and the recent Sent recipients since 5b72c4d. Still open: the on-demand server search (searchRecipients has no caller), directory principals, and the calendar's ParticipantInput, which still offers contacts only.
  • What WEB does: getAutocomplete merges contacts, group entries (as one chip with memberCount), RFC 9670 directory principals and recent Sent recipients, deduped and sanitised (#672) (stores/contact-store.ts:622-707, 23-49; loadRecentRecipients :1118-1142 fed from mail-app.tsx:423; searchRecipients :1144-1154 used by components/email/email-composer.tsx:1175-1212; group chip insertion :1218-1233; changelogs 1.6.x "Recipient autocomplete from Sent, with on-demand server search", 1.7.x group chips).
  • What RN does: suggestions come only from individuals matched with matchesContactSearch (src/screens/ComposeScreen.tsx:367-392); groups are explicitly filtered out and nothing else is consulted. ParticipantInput (calendar) likewise flattens contacts only (src/components/calendar/ParticipantInput.tsx:34-51).
  • Fix hint: add recentRecipients (scan Sent to/cc, 300 msgs) to the contacts store, include groups as a pickable entry that expands to member emails on pick, and reuse sanitizeDisplayName/splitMailbox-style cleanup for names that contain a mailbox (#672).

Viewer integration

• "Add sender to contacts" from the message view missing — P2 — missing — done in d2ed27f (the viewer's address sheet, src/components/email/AddressActionSheet.tsx, offers "Add to contacts" and "Open contact")

  • contact-side done: ContactForm { prefill } seeds email + given/surname (9800ad0), findContactByEmail in the store (26a34d5); the sender sheet in EmailThreadScreen belongs to the viewer agent.
  • What WEB does: contact sidebar/popover on sender click with "Add to contacts" that creates a card with given/surname split from the display name (components/email/email-viewer.tsx:5350-5366, 558-564); also the mobile recipient popover (#306) and /contacts/new?addEmail= deep link (components/contacts/contacts-app.tsx:182-198).
  • What RN does: no contact lookup or "add" action in EmailThreadScreen (grep contact/ContactForm: only SenderAvatar at :794). Only ContactForm's route.params support contactId/addressBookId/asGroup (src/navigation/types.ts:24) — no email/name prefill.
  • Fix hint: add prefill?: { email; name } to the ContactForm route, and a sender-tap sheet in EmailThreadScreen with "Add to contacts" / "Open contact" (lookup by email in useContactsStore).

• Sender-name tap → contact popup missing — P3 — missing — done in d2ed27f (tapping a sender or recipient opens AddressActionSheet, which shows the matching contact and "Open contact")

  • deferred: viewer agent (same sheet as above; findContactByEmail + ContactDetail { contactId } are ready).
  • What WEB does: clicking the sender name opens the contact popup with details/actions (changelog 1.4.x "Show contact popup when clicking the sender name", email-viewer.tsx:392-455).
  • What RN does: none (see previous item).
  • Fix hint: same sheet as above; show the matching card's phone/org and an "Open" that navigates to ContactDetail.

• Contact deep links (/contacts/<id>[/edit], /contacts/new) — P3 — missing

  • partly: /contacts/<id> opens the contact since 5802cae; /contacts/new and /contacts/<id>/edit only open the Contacts tab.
  • What WEB does: parseContactsPath/buildContactsPath (lib/deep-links.ts:323-329), applied once on mount (components/contacts/contacts-app.tsx:182-224).
  • What RN does: src/navigation/linking.ts (5802cae) maps /contacts/<id> to ContactDetail { contactId } and every other contacts path to the tab; it never opens ContactForm.

vCard import / export (lib/vcard.ts vs src/lib/vcard.ts)

• Imported dates are raw strings, not RFC 9553 PartialDate (#224) — birthdays vanish on Stalwart — P1 — bugfix-parity — fixed in e650cb2

  • What WEB does: parseVcardDate converts BDAY/ANNIVERSARY/DEATHDATE/X-ABDATE (basic + extended forms, reduced accuracy, VALUE=text skipped) into {year, month, day} and drops undecodable dates (lib/vcard.ts:360-394, addAnniversary in buildContact ~:480-490; changelog 1.9.x "Import vCard dates as RFC 9553 PartialDate and map common X- extensions (#224)").
  • What RN does: card.anniversaries.a0 = { kind: 'birth', date: val } with the raw string (src/lib/vcard.ts BDAY case ~:687, ANNIVERSARY ~:701, DEATHDATE ~:709), so every imported birthday is rejected by Stalwart (the whole ContactCard/set create fails with invalidProperties, and because of the error-handling finding above the failure is reported only as a generic "import failed for one contact" warning) — i.e. importing a vCard with a BDAY loses the entire contact, not just the date.
  • Fix hint: copy parseVcardDate + addAnniversary from WEB into RN vcard.ts; add a test with BDAY:19850412, BDAY:--0412, BDAY;VALUE=text:circa 1800.

• Vendor X- extensions not imported (X-ABDATE, X-ABRELATEDNAMES, X-SPOUSE/MANAGER/ASSISTANT, X-MAIDENNAME, X-GENDER, X-ANDROID-CUSTOM, X-AIM/X-SKYPE/… IM handles) — P2 — bugfix-parity — fixed in e650cb2

  • What WEB does: X_ONLINE_SERVICES map → onlineServices, RELATION_LABELS/ANDROID_RELATION_TYPES → relatedTo, ANDROID_EVENT_KINDS → anniversaries, X-MAIDENNAME → surname2, X-GENDER → grammaticalGender (lib/vcard.ts:250-323, ~1009-1100, ~1113-1120); export writes X-MAIDENNAME and X-ABDATE for other anniversaries (~1173-1178, ~1280-1283).
  • What RN does: default: break (src/lib/vcard.ts:~858); none of the maps exist (function list: no X_ONLINE_SERVICES, RELATION_LABELS, ANDROID_*). Export skips surname2 and other anniversaries (~:1025-1045).
  • Fix hint: port the maps and the extension cases verbatim; both files otherwise share structure so a near-mechanical diff apply works.

• Apple grouped labels (item1.TEL + item1.X-ABLABEL) are lost — P2 — bugfix-parity — fixed in e650cb2

  • What WEB does: splitGroupPrefix keeps the group, collapseProperties folds a sibling X-ABLABEL into an X-ABLABEL= param, decodeAppleLabel strips _$!<…>!$_ (lib/vcard.ts:116-140, 413-434); labels then land on emails/phones/addresses/online services.
  • What RN does: stripGroupPrefix discards the group (src/lib/vcard.ts:120-131) and properties are keyed by keyPart only (:334-339), so iOS/macOS exports lose every custom label and the X-ABLABEL lines are silently dropped (:~854).
  • Fix hint: port splitGroupPrefix + collapseProperties + RawProperty list handling in parseVCard.

• Org-only vCards are dropped on import and exported without FN (#701) — P2 — bugfix-parity — fixed in e650cb2

  • What WEB does: hasOrg counts as identity in buildContact (lib/vcard.ts:~1123-1127); generateSingleVCard falls back to the org name for the mandatory FN (~:1158-1162).
  • What RN does: if (!hasName && !hasEmail && card.kind !== 'group') return null (src/lib/vcard.ts:~893-895) so a company card with only ORG+TEL is skipped; export emits no FN/N when there is no personal name (~:932-936), producing an invalid vCard (FN is required by RFC 6350) that the RN importer itself would then reject.
  • Fix hint: apply the two WEB lines.

• Only one NICKNAME survives import — P3 — bugfix-parity — fixed in e650cb2

  • What WEB does: card.nicknames[\n${idx}`] (lib/vcard.ts` NICKNAME case).
  • What RN does: card.nicknames.n0 = { name: val } overwrites (src/lib/vcard.ts NICKNAME case ~:548).
  • Fix hint: index like WEB.

• Import target defaults to the first book and cannot be changed from Settings — P3 — partial — fixed in bc4c57e

  • What WEB does: client.createContact without addressBookIds files into the isDefault book (lib/jmap/client.ts:5095-5101).
  • What RN does: ContactsSettings passes books[0] with no onChangeTarget (src/components/settings/ContactsSettings.tsx:54, 269-275); ContactsScreen allows changing the target but also starts at addressBooks[0] unless a book category is active (src/screens/ContactsScreen.tsx:201-204, 476, 480-486).
  • Fix hint: prefer isDefault; pass onChangeTarget in settings too.

• Import keeps the source UID (fine) but nothing mints one when absent — covered by the #644 finding above; also importContacts swallows per-card failures with only a console.warn (src/stores/contacts-store.ts:206-208) so "Imported 0 contacts" is the only feedback. P3 — add a failure count to the result sheet. — fixed in 26a34d5

  • The result sheet now shows how many cards failed to import.

Trusted senders

• Trusted-senders settings show only the local list; synced book entries are invisible and cannot be removed — P2 — partial — fixed in 78114b6

  • What WEB does: modal shows the address-book entries when the feature is on, adds/removes through addToTrustedSendersBook/removeFromTrustedSendersBook, and settings show the synced count (components/trusted-senders-modal.tsx:22-48; components/settings/content-senders-settings.tsx:25-40, 77-82).
  • What RN does: ContentSendersSettings reads/writes only settings-store.trustedSenders (src/components/settings/ContentSendersSettings.tsx:19-21, 100-144); removeFromTrustedSendersBook exists in the store (src/stores/contacts-store.ts:323-333) but has no caller. A sender trusted from the viewer is written to both places (src/components/EmailBodyView.tsx:644-651), so deleting it in settings only removes the local copy and the book keeps trusting it (EmailBodyView.tsx:513-516).
  • Fix hint: in the modal, list trustedSenders ∪ trustedSenderEmails, mark book entries, and call removeFromTrustedSendersBook (+ local remove) on delete; show the union count.

• trustedSendersAddressBook setting is dead (false, no setter, no toggle) — book is consulted unconditionally — P3 — partial — fixed in 78114b6

  • Setting is boolean | null with a "Sync trusted senders to address book" toggle. Until d89e331 it switched itself on for a contacts-capable account, and the viewer then trusted every contact in every book; it now stays off until the user turns it on, and only the Trusted Senders book counts (the webmail still auto-enables it).
  • What WEB does: null until the account proves contacts support, then auto-true (stores/auth-store.ts:380-385, stores/settings-store.ts:361,593); toggle in settings (content-senders-settings.tsx:77-82); the book is only loaded/used when enabled (mail-app.tsx:199-203, email-viewer.tsx:1705).
  • What RN does: default false, no setter (src/stores/settings-store.ts:106,239); EmailBodyView loads the book regardless and ORs trustedSenderEmails into the trust check (:480-485, 513-516); the addressBookEmails branch (treats every contact as trusted) is gated on the dead flag (:486-498) so it never runs.
  • Fix hint: either drop the flag and the dead addressBookEmails branch, or expose a "Sync trusted senders to address book" toggle that gates the passive load and the addToTrustedSendersBook write.

• Race: trusting a sender while the passive book load is in flight silently fails — P2 — rn-only-bug — fixed in 26a34d5

  • What WEB does: single-flight promise shared by all callers (stores/contact-store.ts:184-185, 1156-1199), so addToTrustedSendersBook awaits the load and then has a bookId.
  • What RN does: loadTrustedSendersBook returns immediately when trustedSendersLoading is true (src/stores/contacts-store.ts:279); addToTrustedSendersBook then reads bookId === null and throws (:312-317), which the viewer swallows (EmailBodyView.tsx:650). The passive load is kicked off by the same screen a moment earlier (:483-485), so the very first "Trust sender" after app start is likely to hit this.
  • Fix hint: keep the in-flight promise in a module variable and return it; if the passive load found no book and createIfMissing is true, create it after the await.

• Duplicate "Trusted Senders" books are not consolidated and the pick is non-deterministic (#730) — P3 — bugfix-parity — fixed in 26a34d5

  • Deterministic pick (sorted by id); consolidation not ported.
  • What WEB does: sorts matches by id, uses the first, merges the rest and deletes them (stores/contact-store.ts:1169-1187, 208-245); getAddressBooks({throwOnError}) prevents minting on a failed fetch.
  • What RN does: books.find(b => b.name === …) (src/stores/contacts-store.ts:283) — order-dependent; if the web already created a duplicate pair, RN may trust a different subset than web. RN only creates on explicit add (:284-290) and fetchAddressBooks throws on error, so RN itself does not mint duplicates.
  • Fix hint: sort by id before picking; optional consolidation.

• Trusted-sender card stores no display name; "Name " input not parsed — P3 — partial — fixed in 26a34d5

  • What WEB does: parses Name <email> and stores name.full (stores/contact-store.ts:1201-1225).
  • What RN does: lower-cases the whole string and stores emails only (src/stores/contacts-store.ts:308-321); a Name <email> string (e.g. typed in settings) becomes an invalid address.
  • Fix hint: reuse the WEB regex.

• Auto-trust reply recipients missing — P3 — missing — done in 5b72c4d (area 04)

  • deferred: composer agent; addToTrustedSendersBook now accepts Name <email> and never races the passive load (26a34d5).
  • What WEB does: on reply/replyAll every To/Cc recipient is added to the trusted book (components/email/email-composer.tsx:2284-2292; changelog 1.4.x "Auto-add recipients to trusted senders when replying").
  • What RN does: ComposeScreen has no trusted-sender code (grep trusted: none).
  • Fix hint: after a successful send in reply mode call addToTrustedSendersBook (+ addTrustedSender) for each outgoing To/Cc.

Activity / misc

• Contact activity: upcoming events come only from the already-loaded calendar cache — P3 — partial — fixed in 0e51465
  • What WEB does: queries the server for the next 365 days (components/contacts/contact-activity.tsx:133-169).
  • What RN does: filters useCalendarStore().events (src/components/contacts/ContactActivity.tsx:90-91, 127-142), i.e. only the range the calendar tab happened to load; on a fresh start it is empty.
  • Fix hint: call the RN calendar API for [now, now+365d] with a participant filter, falling back to the cache.

Verified at parity (brief list, so the fixer knows what NOT to redo)

• Address book list/create/rename/delete with myRights checks (src/components/settings/ContactsSettings.tsx, AddressBookPickerSheet); inline "New address book…" in the move sheet (WEB #415).
• Move contacts between books (single from detail, bulk from list) via addressBookIds patch (contacts-store.ts:237-241) — RN equivalent of WEB drag-and-drop.
• Group by first letter with sticky headers + settings toggle (ContactsScreen.tsx:158-162, ContactsSettings.tsx:132-137); sort by display name, or by last name since 1827748 (#963); the sort no longer re-runs on every search keystroke since e6be892.
• Search over name/emails/phones/orgs (RN also matches keywords).
• Detail screen renders every WEB field block: emails/phones with contexts+features+labels, addresses (components, flat, timezone), org/units/titles/roles, anniversaries with age, gender/pronouns, languages, personalInfo, online services, calendar URIs, crypto keys, categories, relatedTo, notes, address book names, created/updated; quick actions call/SMS/mail/share; copy via long-press.
• Contact form: prefix/given/middle/surname/suffix, nickname, display name (name.full), multiple emails/phones with context + phone feature pills, addresses as RFC 9553 components, multiple orgs (org/department/title/role), anniversaries with native date picker, online services, personalInfo w/ level, gender+pronouns, calendar URIs, categories (chips + suggestions from existing keywords), multiple notes, photo pick/remove, address book pick, dirty-state discard confirm, email regex validation, media: {} when photo removed (equivalent of WEB media: null).
• name.full display fallback (#179), getContactPrimaryEmail with pref. name.full (the vCard FN) is written on every form, "add sender" and import save since a734d0a (#430).
• Group detail: member list resolved via id/uid/urn:uuid: (contacts-store.ts:401-415), add members via ContactPickerSheet, remove member, delete group, email all.
• Tags (keywords) = WEB categories: drawer section with counts, filter by tag, bulk assign via TagAssignSheet, per-contact edit in form.
• vCard import sheet: file picker, 5 MB cap, parse, duplicate detection by email (detectDuplicates identical), select all/none, target book, result count; export all (settings) and single (detail) with share sheet; multi-vCard files; QUOTED-PRINTABLE + charset decode (RN has a Hermes-safe decodeBytes), RFC 6868 params, KIND/MEMBER, PHOTO/LOGO/SOUND, RFC 6474/6715/8605/9554 properties.
• Contact activity: recent emails via from/to OR filter (limit 5), opens the thread.
• Trusted senders: same book name constant, passive load, add on "Trust sender" in the viewer, isTrustedAddressBookSender check.
• Contacts tab hidden when the session lacks urn:ietf:params:jmap:contacts (src/lib/capabilities.ts:29-31, App.tsx:170-179) — WEB 1.8.x "Hide Contacts and Calendars when the account lacks the JMAP capability".
• Push StateChange for AddressBook/ContactCard triggers refetch (contacts-store.ts:152-168, App.tsx:390-396); contacts cache persisted for instant render; selected category persisted.
• Contact store reset on logout/account switch (src/stores/auth-store.ts:58,76,113,179,379) — the RN counterpart of the 583e20d9 namespacing fix (single-account store, so no id-form flip).

N/A on mobile

• Pro multi-account aggregation (hooks/use-pro-multi-account-contacts.ts, fetchAllAccountsContacts, :: id namespacing) — Pro shell only; RN keeps one account active and resets the store on switch.
• Local-storage (non-JMAP) contact fallback (supportsSync === false, local-<uuid> ids) — RN hides the tab when contacts are unsupported.
• Drag-and-drop to address books / categories, right-click context menus, Ctrl/Shift range selection, resizable panes, keyboard shortcuts — replaced by long-press multi-select + sheets.
• Print contact (components/contacts/contact-print.ts).
• Plugin contact APIs and the contact-cryptokeys plugin slot.
• mailto:/tel: handoff differences (RN uses Linking).
• Native issue #34 (device contacts / calendar sync adapters) is a feature request, not a parity item; note that a device sync would want the UID (#644) and PartialDate (#224) fixes above first.
