+
+# Person
+
+A person is collection data, independent of an account or collection membership.
+Applications reference the stable `id`, not a name, file path, email address,
+account subject, or membership ID. Collections choose their own local type and
+field names through explicit `implements` mappings.
+
+`name` is a collection-owned display label. `identities` optionally associates
+this person with one or more accounts through issuer/subject pairs. A person
+without a Connect account is valid. The same record can travel between hosted,
+relay, local, and exported collections without rewriting its identity references.
+
+## Identity matching
+
+An identity service supplies the authenticated caller's issuer and subject.
+Subjects are opaque, account-wide identifiers, stable across email changes,
+collection memberships, and removal/rejoining. Different identity issuers may
+use the same subject; both fields must match exactly. Consumers must not trim,
+case-fold, resolve redirects, or otherwise normalize either field when matching.
+Copy the issuer value supplied by the service, including its trailing-slash
+convention. Never derive the issuer from the current collection authority URL.
+HTTP issuers support explicitly configured development and self-hosted instances;
+production deployments should use HTTPS.
+
+An application resolves an identity across all implementing person records:
+
+- No matching person: unlinked, not anonymous authentication and not an error.
+- Exactly one matching record with an unambiguous person ID: linked.
+- Multiple matching records, or multiple records with that person's ID:
+  ambiguous. Do not pick the first match, merge records, or overwrite a link.
+
+A partial or failed query cannot establish that a match is unique. Cross-record
+uniqueness is a collection/application invariant, not something this JSON Schema
+can prove. Consumers must handle ambiguity even if a starter type has a local
+uniqueness constraint: several local types can implement this contract.
+
+## Editable data, not security authority
+
+Identity associations have exactly the same trust as other editable collection
+data. Editing one may change an application's "Assigned to me" view. It must
+never change authentication, membership, permissions, authenticated audit
+attribution, or proof of identity to another service. Schema conformance proves
+shape, not that an identity association is truthful.
+
+"Link this person to me" is an ordinary record update using the authenticated
+caller's identity. Never infer a link from a matching email or display name.
+Membership and current account display names come from the identity service,
+not frontmatter. A person association must never invite someone or grant access.
+
+## Lifecycle and portability
+
+Renaming or moving a record does not change its ID. Removing a member does not
+delete their person record or task assignments. Deleting a record leaves
+unresolved references; consumers should preserve these rather than silently
+unassigning work. Reusing an ID for a different person changes every reference
+and should not be treated as a routine rename.
+
+Copying records preserves account associations, but never copies collection
+access. Multiple issuer/subject entries let one person represent accounts at
+different identity services. Account deletion or an issuer migration may leave
+an unresolved identity association; do not automatically rebind it to a newly
+created account. Stored names and identity references remain collection data
+subject to that collection's retention and editing policies.
+
+Account-wide subjects deliberately allow correlation across collections. This
+is a portability trade-off, not an anonymity guarantee. Never store passwords,
+access tokens, refresh tokens, or other credentials in these fields.
+
+## Contact information
+
+This contract does not define another address book. A local type can also
+implement `mdbase.contact` for compact contact semantics, or
+`mdbase.jscontact.card` when it intentionally stores that interchange shape.
+The starter Person type implements both Person and Contact.

+# Person
+
+A person is collection data, independent of an account or collection membership.
+Other records refer to a person with an ordinary mdbase link to the person's
+record, such as `"[[Alex Rivera]]"`, declared in the referring type's
+`collection.links` and resolved with the collection's own link rules. Never
+refer to a person by name text, email address, account subject, or membership
+ID. Collections choose their own local type and field names through explicit
+`implements` mappings.
+
+Version 2.0.0 removes the separate `id` field of 1.0.0. Link resolution already
+identifies the record, and rename reference updates keep links current, so a
+second identifier only created a way for the two to disagree.

+---
+
+# Person
+
+A person is collection data, independent of an account or collection membership.
+Applications reference the stable `id`, not a name, file path, email address,
+account subject, or membership ID. Collections choose their own local type and
+field names through explicit `implements` mappings.
+
+`name` is a collection-owned display label. `identities` optionally associates
+this person with one or more accounts through issuer/subject pairs. A person
+without a Connect account is valid. The same record can travel between hosted,
+relay, local, and exported collections without rewriting its identity references.
+
+## Identity matching
+
+An identity service supplies the authenticated caller's issuer and subject.
+Subjects are opaque, account-wide identifiers, stable across email changes,
+collection memberships, and removal/rejoining. Different identity issuers may
+use the same subject; both fields must match exactly. Consumers must not trim,
+case-fold, resolve redirects, or otherwise normalize either field when matching.
+Copy the issuer value supplied by the service, including its trailing-slash
+convention. Never derive the issuer from the current collection authority URL.
+HTTP issuers support explicitly configured development and self-hosted instances;
+production deployments should use HTTPS.
+
+An application resolves an identity across all implementing person records:
+
+- No matching person: unlinked, not anonymous authentication and not an error.
+- Exactly one matching record with an unambiguous person ID: linked.
+- Multiple matching records, or multiple records with that person's ID:
+  ambiguous. Do not pick the first match, merge records, or overwrite a link.
+
+A partial or failed query cannot establish that a match is unique. Cross-record
+uniqueness is a collection/application invariant, not something this JSON Schema
+can prove. Consumers must handle ambiguity even if a starter type has a local
+uniqueness constraint: several local types can implement this contract.
+
+## Editable data, not security authority
+
+Identity associations have exactly the same trust as other editable collection
+data. Editing one may change an application's "Assigned to me" view. It must
+never change authentication, membership, permissions, authenticated audit
+attribution, or proof of identity to another service. Schema conformance proves
+shape, not that an identity association is truthful.
+
+"Link this person to me" is an ordinary record update using the authenticated
+caller's identity. Never infer a link from a matching email or display name.
+Membership and current account display names come from the identity service,
+not frontmatter. A person association must never invite someone or grant access.
+
+## Lifecycle and portability
+
+Renaming or moving a record does not change its ID. Removing a member does not
+delete their person record or task assignments. Deleting a record leaves
+unresolved references; consumers should preserve these rather than silently
+unassigning work. Reusing an ID for a different person changes every reference
+and should not be treated as a routine rename.
+
+Copying records preserves account associations, but never copies collection
+access. Multiple issuer/subject entries let one person represent accounts at
+different identity services. Account deletion or an issuer migration may leave
+an unresolved identity association; do not automatically rebind it to a newly
+created account. Stored names and identity references remain collection data
+subject to that collection's retention and editing policies.
+
+Account-wide subjects deliberately allow correlation across collections. This
+is a portability trade-off, not an anonymity guarantee. Never store passwords,
+access tokens, refresh tokens, or other credentials in these fields.
+
+## Contact information
+
+This contract does not define another address book. A local type can also
+implement `mdbase.contact` for compact contact semantics, or
+`mdbase.jscontact.card` when it intentionally stores that interchange shape.
+The starter Person type implements both Person and Contact.

+
+# Person
+
+A person is collection data, independent of an account or collection membership.
+Other records refer to a person with an ordinary mdbase link to the person's
+record, such as `"[[Alex Rivera]]"`, declared in the referring type's
+`collection.links` and resolved with the collection's own link rules. Never
+refer to a person by name text, email address, account subject, or membership
+ID. Collections choose their own local type and field names through explicit
+`implements` mappings.
+
+Version 2.0.0 removes the separate `id` field of 1.0.0. Link resolution already
+identifies the record, and rename reference updates keep links current, so a
+second identifier only created a way for the two to disagree.
+
+`name` is a collection-owned display label. `identities` optionally associates
+this person with one or more accounts through issuer/subject pairs. A person
+without a Connect account is valid. The same record can travel between hosted,
+relay, local, and exported collections without rewriting its identity references.

+# Person
+
+Create a stable ID when adding a person, for example `person_` followed by a
+random UUID. Keep it when copying the note to another collection or renaming
+its file. Apps use this ID for assignments and other person references.
+
+```yaml
+type: person
+id: person_2c1343ec-cac1-4d58-98c9-41736f4de7db
+name: Callum
+identities:
+  - issuer: https://connect.example
+    subject: usr_789
+```
+
+Use the actual issuer and subject supplied by Connect, not the example values.
+Omit `identities` for people without accounts. Email is contact information,
+not a way to establish an identity association. Linking a person does not
+invite them or grant access to this collection.
+
+Identity associations and contact labels are ordinary editable data. They are
+not proof of authentication. Avoid duplicate person IDs or identity pairs
+across person notes; applications must report ambiguity rather than guess.
+
+The inline schema belongs to the collection. Add local fields or rename them
+and update the explicit contract mappings without editing published contracts.

+
+# Person
+
+Use one note per individual, whether or not they have a Connect account. This
+single type supplies both a Person record and optional Contact details. You do
+not need a second Contact note for the same person.
+
+## Start with a name
+
+```yaml
+type: person
+name: Alex Rivera
+```
+
+Other notes refer to this person with an ordinary link to this note, such as
+`[[Alex Rivera]]` in a task's `assignees`. Links to this note appear in its
+backlinks. Rename or move the note with a tool that updates references, as mdbase
+and Obsidian do, so those links stay current. Reusing a person's file name for
+somebody else redirects existing links to the wrong person.
+
+The name is your collection's display label. Full names, preferred names and
+single names are equally valid. There is no required first-name/last-name split.
+
+## Add only the contact details you need
+
+Email, phone, organisation and birthday are optional. Omit unknown values rather
+than filling them with empty strings or guesses. Store phone numbers as text,
+including an international prefix or extension when helpful. Birthday currently
+requires a complete date; partial dates need a separately configured local field.
+Keep free-form context in the Markdown body and be deliberate about sensitive
+personal information in shared collections.
+
+This starter describes individuals. Existing organisation and group records can
+continue using their Contact-compatible type; setting someone's affiliation does
+not turn their Person note into an organisation record.
+
+## Link accounts deliberately
+
+The editor's **Link this record to me** action uses the authenticated account's
+actual issuer and subject. If configuring these manually, copy both exact values
+from the identity service. Do not guess them from an email, display name, or the
+server hosting this collection. Multiple entries may represent the same person
+at different identity services. Omit `identities` when there is no account to link.
+
+Associations are ordinary editable data, not authentication or proof of identity.
+Linking never invites someone, grants access, or changes collection membership.
+Never put credentials in a person record. Avoid linking the same account from
+several notes: applications should report ambiguity, not guess which
+record to use. Account deletion or recreation is not permission to reassign an
+old association automatically.
+
+## Keep the collection's own shape
+
+The inline schema belongs to this collection. You may add local fields, or rename
+fields and update their explicit `implements` mappings. Apps use those mappings
+for the Person and Contact contracts; they need not assume your local field names.
+Additional fields remain part of the note but do not automatically become shared
+contract fields. Do not edit published contracts to customise this type.
+
+Installing a newer starter does not overwrite an existing customised type or
+migrate your address book. Converting an existing individual Contact to Person
+should be a reviewed edit of that one note, preserving its path, fields and body.

+# Task
+
+This type definition implements the TaskNotes contract for this mdbase collection.
+Its JSON Schema describes persisted task frontmatter; collection and lifecycle
+metadata describe generic mdbase behavior; `implements` maps the portable
+TaskNotes task view and supplies TaskNotes behavior.
+
+Changes made here are loaded by TaskNotes. Portable changes made in TaskNotes
+settings are written back while unknown extensions are preserved.

Collections choose their own local type and\nfield names through explicit `implements` mappings.\n\n`name` is a collection-owned display label. `identities` optionally associates\nthis person with one or more accounts through issuer/subject pairs. A person\nwithout a Connect account is valid. The same record can travel between hosted,\nrelay, local, and exported collections without rewriting its identity references.\n\n## Identity matching\n\nAn identity service supplies the authenticated caller's issuer and subject.\nSubjects are opaque, account-wide identifiers, stable across email changes,\ncollection memberships, and removal/rejoining. Different identity issuers may\nuse the same subject; both fields must match exactly. Consumers must not trim,\ncase-fold, resolve redirects, or otherwise normalize either field when matching.\nCopy the issuer value supplied by the service, including its trailing-slash\nconvention. Never derive the issuer from the current collection authority URL.\nHTTP issuers support explicitly configured development and self-hosted instances;\nproduction deployments should use HTTPS.\n\nAn application resolves an identity across all implementing person records:\n\n- No matching person: unlinked, not anonymous authentication and not an error.\n- Exactly one matching record with an unambiguous person ID: linked.\n- Multiple matching records, or multiple records with that person's ID:\n  ambiguous. Do not pick the first match, merge records, or overwrite a link.\n\nA partial or failed query cannot establish that a match is unique. Cross-record\nuniqueness is a collection/application invariant, not something this JSON Schema\ncan prove. Consumers must handle ambiguity even if a starter type has a local\nuniqueness constraint: several local types can implement this contract.\n\n## Editable data, not security authority\n\nIdentity associations have exactly the same trust as other editable collection\ndata. Editing one may change an application's \"Assigned to me\" view. It must\nnever change authentication, membership, permissions, authenticated audit\nattribution, or proof of identity to another service. Schema conformance proves\nshape, not that an identity association is truthful.\n\n\"Link this person to me\" is an ordinary record update using the authenticated\ncaller's identity. Never infer a link from a matching email or display name.\nMembership and current account display names come from the identity service,\nnot frontmatter. A person association must never invite someone or grant access.\n\n## Lifecycle and portability\n\nRenaming or moving a record does not change its ID. Removing a member does not\ndelete their person record or task assignments. Deleting a record leaves\nunresolved references; consumers should preserve these rather than silently\nunassigning work. Reusing an ID for a different person changes every reference\nand should not be treated as a routine rename.\n\nCopying records preserves account associations, but never copies collection\naccess. Multiple issuer/subject entries let one person represent accounts at\ndifferent identity services. Account deletion or an issuer migration may leave\nan unresolved identity association; do not automatically rebind it to a newly\ncreated account. Stored names and identity references remain collection data\nsubject to that collection's retention and editing policies.\n\nAccount-wide subjects deliberately allow correlation across collections. This\nis a portability trade-off, not an anonymity guarantee. Never store passwords,\naccess tokens, refresh tokens, or other credentials in these fields.\n\n## Contact information\n\nThis contract does not define another address book. A local type can also\nimplement `mdbase.contact` for compact contact semantics, or\n`mdbase.jscontact.card` when it intentionally stores that interchange shape.\nThe starter Person type implements both Person and Contact.\n"

Different identity issuers may\nuse the same subject; both fields must match exactly. Consumers must not trim,\ncase-fold, resolve redirects, or otherwise normalize either field when matching.\nCopy the issuer value supplied by the service, including its trailing-slash\nconvention. Never derive the issuer from the current collection authority URL.\nHTTP issuers support explicitly configured development and self-hosted instances;\nproduction deployments should use HTTPS.\n\nAn application resolves an identity across all implementing person records:\n\n- No matching person: unlinked, not anonymous authentication and not an error.\n- Exactly one matching record with an unambiguous person ID: linked.\n- Multiple matching records, or multiple records with that person's ID:\n  ambiguous. Do not pick the first match, merge records, or overwrite a link.\n\nA partial or failed query cannot establish that a match is unique. Cross-record\nuniqueness is a collection/application invariant, not something this JSON Schema\ncan prove. Consumers must handle ambiguity even if a starter type has a local\nuniqueness constraint: several local types can implement this contract.\n\n## Editable data, not security authority\n\nIdentity associations have exactly the same trust as other editable collection\ndata. Editing one may change an application's \"Assigned to me\" view. It must\nnever change authentication, membership, permissions, authenticated audit\nattribution, or proof of identity to another service. Schema conformance proves\nshape, not that an identity association is truthful.\n\n\"Link this person to me\" is an ordinary record update using the authenticated\ncaller's identity. Never infer a link from a matching email or display name.\nMembership and current account display names come from the identity service,\nnot frontmatter. A person association must never invite someone or grant access.\n\n## Lifecycle and portability\n\nRenaming or moving a record does not change its ID. Removing a member does not\ndelete their person record or task assignments. Deleting a record leaves\nunresolved references; consumers should preserve these rather than silently\nunassigning work. Reusing an ID for a different person changes every reference\nand should not be treated as a routine rename.\n\nCopying records preserves account associations, but never copies collection\naccess. Multiple issuer/subject entries let one person represent accounts at\ndifferent identity services. Account deletion or an issuer migration may leave\nan unresolved identity association; do not automatically rebind it to a newly\ncreated account. Stored names and identity references remain collection data\nsubject to that collection's retention and editing policies.\n\nAccount-wide subjects deliberately allow correlation across collections. This\nis a portability trade-off, not an anonymity guarantee.

This\nsingle type supplies both a Person record and optional Contact details. You do\nnot need a second Contact note for the same person.\n\n## Start with a name\n\n```yaml\ntype: person\nname: Alex Rivera\n```\n\nOther notes refer to this person with an ordinary link to this note, such as\n`[[Alex Rivera]]` in a task's `assignees`. Links to this note appear in its\nbacklinks. Rename or move the note with a tool that updates references, as mdbase\nand Obsidian do, so those links stay current. Reusing a person's file name for\nsomebody else redirects existing links to the wrong person.\n\nThe name is your collection's display label. Full names, preferred names and\nsingle names are equally valid. There is no required first-name/last-name split.\n\n## Add only the contact details you need\n\nEmail, phone, organisation and birthday are optional. Omit unknown values rather\nthan filling them with empty strings or guesses. Store phone numbers as text,\nincluding an international prefix or extension when helpful. Birthday currently\nrequires a complete date; partial dates need a separately configured local field.\nKeep free-form context in the Markdown body and be deliberate about sensitive\npersonal information in shared collections.\n\nThis starter describes individuals. Existing organisation and group records can\ncontinue using their Contact-compatible type; setting someone's affiliation does\nnot turn their Person note into an organisation record.\n\n## Link accounts deliberately\n\nThe editor's **Link this record to me** action uses the authenticated account's\nactual issuer and subject. If configuring these manually, copy both exact values\nfrom the identity service. Do not guess them from an email, display name, or the\nserver hosting this collection. Multiple entries may represent the same person\nat different identity services. Omit `identities` when there is no account to link.\n\nAssociations are ordinary editable data, not authentication or proof of identity.\nLinking never invites someone, grants access, or changes collection membership.\nNever put credentials in a person record. Avoid linking the same account from\nseveral notes: applications should report ambiguity, not guess which\nrecord to use. Account deletion or recreation is not permission to reassign an\nold association automatically.\n\n## Keep the collection's own shape\n\nThe inline schema belongs to this collection. You may add local fields, or rename\nfields and update their explicit `implements` mappings. Apps use those mappings\nfor the Person and Contact contracts; they need not assume your local field names.\nAdditional fields remain part of the note but do not automatically become shared\ncontract fields. Do not edit published contracts to customise this type.\n\nInstalling a newer starter does not overwrite an existing customised type or\nmigrate your address book. Converting an existing individual Contact to Person\nshould be a reviewed edit of that one note, preserving its path, fields and body.\n"

+# Person
+
+Create a stable ID when adding a person, for example `person_` followed by a
+random UUID. Keep it when copying the note to another collection or renaming
+its file. Apps use this ID for assignments and other person references.
+
+```yaml
+type: person
+id: person_2c1343ec-cac1-4d58-98c9-41736f4de7db
+name: Callum
+identities:
+  - issuer: https://connect.example
+    subject: usr_789
+```
+
+Use the actual issuer and subject supplied by Connect, not the example values.
+Omit `identities` for people without accounts. Email is contact information,
+not a way to establish an identity association. Linking a person does not
+invite them or grant access to this collection.
+
+Identity associations and contact labels are ordinary editable data. They are
+not proof of authentication. Avoid duplicate person IDs or identity pairs
+across person notes; applications must report ambiguity rather than guess.
+
+The inline schema belongs to the collection. Add local fields or rename them
+and update the explicit contract mappings without editing published contracts.

+
+# Person
+
+Use one note per individual, whether or not they have a Connect account. This
+single type supplies both a Person record and optional Contact details. You do
+not need a second Contact note for the same person.
+
+## Start with a name
+
+```yaml
+type: person
+name: Alex Rivera
+```
+
+Other notes refer to this person with an ordinary link to this note, such as
+`[[Alex Rivera]]` in a task's `assignees`. Links to this note appear in its
+backlinks. Rename or move the note with a tool that updates references, as mdbase
+and Obsidian do, so those links stay current. Reusing a person's file name for
+somebody else redirects existing links to the wrong person.
+
+The name is your collection's display label. Full names, preferred names and
+single names are equally valid. There is no required first-name/last-name split.
+
+## Add only the contact details you need
+
+Email, phone, organisation and birthday are optional. Omit unknown values rather
+than filling them with empty strings or guesses. Store phone numbers as text,
+including an international prefix or extension when helpful. Birthday currently
+requires a complete date; partial dates need a separately configured local field.
+Keep free-form context in the Markdown body and be deliberate about sensitive
+personal information in shared collections.
+
+This starter describes individuals. Existing organisation and group records can
+continue using their Contact-compatible type; setting someone's affiliation does
+not turn their Person note into an organisation record.
+
+## Link accounts deliberately
+
+The editor's **Link this record to me** action uses the authenticated account's
+actual issuer and subject. If configuring these manually, copy both exact values
+from the identity service. Do not guess them from an email, display name, or the
+server hosting this collection. Multiple entries may represent the same person
+at different identity services. Omit `identities` when there is no account to link.
+
+Associations are ordinary editable data, not authentication or proof of identity.
+Linking never invites someone, grants access, or changes collection membership.
+Never put credentials in a person record. Avoid linking the same account from
+several notes: applications should report ambiguity, not guess which
+record to use. Account deletion or recreation is not permission to reassign an
+old association automatically.
+
+## Keep the collection's own shape
+
+The inline schema belongs to this collection. You may add local fields, or rename
+fields and update their explicit `implements` mappings. Apps use those mappings
+for the Person and Contact contracts; they need not assume your local field names.
+Additional fields remain part of the note but do not automatically become shared
+contract fields. Do not edit published contracts to customise this type.
+
+Installing a newer starter does not overwrite an existing customised type or
+migrate your address book. Converting an existing individual Contact to Person
+should be a reviewed edit of that one note, preserving its path, fields and body.

+# Task
+
+This type definition implements the TaskNotes contract for this mdbase collection.
+Its JSON Schema describes persisted task frontmatter; collection and lifecycle
+metadata describe generic mdbase behavior; `implements` maps the portable
+TaskNotes task view and supplies TaskNotes behavior.
+
+Changes made here are loaded by TaskNotes. Portable changes made in TaskNotes
+settings are written back while unknown extensions are preserved.
