Merge pull request 'Fix #169: keep citation links on GEDCOM export' (#232) from fix-gedcom-citation-export into main

Export emitted SOUR records but never the per-fact SOUR links, so a
Provenance→Provenance round-trip destroyed the sources graph (citations were
dropped). Emit citation links on the facts they sit on:
- person-level → 1 SOUR @Sx@ (2 PAGE)
- name-level   → 2 SOUR under 1 NAME
- event-level  → 2 SOUR under the event (incl. partnership events in FAM)
- relationship → 1 SOUR under FAM
Citations whose source didn't export are skipped.

Test: a person + event citation round-trips through export→import into a fresh
tree with their pages intact. GEDCOM suite 6 passed.

Closes #169

 5. **Sources are first-class.** Don't model citations as free-text afterthoughts. A `Source` is a reusable entity; a `Citation` links it to a specific fact.
 6. **Only legal data sources.** Ship scrapers/connectors only for permissible sources (FamilySearch API, Find A Grave, WikiTree, BLM/GLO, USGS, public-domain newspapers, public county records). Never add connectors for paywalled/terms-prohibited sites (Ancestry, MyHeritage, 23andMe).
 7. **Everything is configurable via environment.** Auth, mail, object storage, database, model providers, scrapers — all twelve-factor. No hard-coded endpoints or keys.
+8. **Full CRUD on every object.** Every stored entity (person, name, event, relationship, source, citation, media, tree, …) must support create, read, **update**, and delete — in the API *and* the UI. Historical research is constant correction and new information, so nothing is write-once. Any new feature or data type ships with all four operations; an entity you can create but not edit is a bug.

+> Phase references map onto the existing 0–9 roadmap. "NN#" = non-negotiable invariant.
+
+---
+
+## 1. Executive summary
+
+**Where Provenance is strong today.** The foundation is genuinely solid and, in several places, ahead of the OSS field:
+
+- **Sources-first spine is real.** A reusable `Source` + per-fact `Citation` two-tier model with a `exactly_one_target` CHECK constraint, confidence enum, and full backend CRUD. This is the architectural thing webtrees/Gramps get right and most commercial tools bury. (Caveat: citations are silently dropped on GEDCOM *export* — see below.)
+- **Privacy architecture is the right shape.** A single `privacy.py` engine, `TenantScoped` mixin on every row, living-person heuristic (`is_possibly_living`, unknown-birth-treated-as-living), and media served **through the backend rather than via raw S3 URLs**. The *shape* is correct; coverage is not yet complete (the media endpoint and several child resources don't yet apply `person_visibility` — see §2.4, §2.10).
+- **Non-destructive by design.** Soft-delete with timed purge worker, immutable `AuditEntry` (before/after JSONB, `actor_type` ready for the assistant), GEDCOM merge that copies rather than overwrites, full account export/import.
+- **Modeling maturity.** Typed parent/child qualifiers (biological/adoptive/step/foster/donor/guardian), typed alternate names with one-primary invariant, dual verbatim+normalized dates, duplicate-relationship guards, UUID surrogate keys.
+- **Standards core.** GEDCOM 5.5.1 import/export is **functional** (with preview/merge-vs-create resolution UI), pg_trgm fuzzy name search, multi-tenant tree hosting with visibility tiers. Round-trip *fidelity* has four tracked gaps (citation links, custom tags, PLAC coords/hierarchy, non-UTF-8 encoding) — see §2.11.
+
+**Documentation-vs-code gaps to correct now (per "docs travel with code").** Three repo claims are not yet true and should be edited in the same spirit they were written:
+
+- **ChangeProposal is documented as landed but does not exist.** CLAUDE.md states the core data model (ARCHITECTURE §5) landed / "Phase 0 complete," but `ChangeProposal` — part of §5 and the load-bearing AI invariant — has no model, migration, or schema. Either scope it out of the "landed" claim or build it; don't leave the docs asserting it.
+- **pgvector is claimed as used; it is not.** Only `pg_trgm` is created. ARCHITECTURE references pgvector for match ranking.
+- **i18n "from day one" is documented but unmet.** PRD §6 promises externalized strings; every label is a hardcoded literal.
+
+These three doc edits are themselves trivial quick wins (see §3).
+
+**The biggest gaps vs commercial (Ancestry / MyHeritage / FamilySearch).** Provenance is not trying to be a record provider, and correctly so — but it is missing several things mainstream users treat as table stakes:
+
+- **No record hints, no "save to tree," no connector framework.** The entire SourceConnector layer (FamilySearch/Find A Grave/WikiTree) is unbuilt — this gates AI search, hints, and auto-citation.
+- **No person merge outside GEDCOM import.** Merging duplicate people is fundamental hygiene and is currently impossible in-tree — the single highest-value near-term matching gap.
+- **No maps at all.** No place autocomplete, no geocoding, no interactive/migration/birthplace maps — a glaring hole for an app whose thesis is *family **and** land*.
+- **No report/print/PDF output.** Charts render on-screen only; there is no Ahnentafel, family group sheet, narrative report, or any PDF/SVG/HTML export. The whole "Charts, reports & printing" category is on-screen-viewing only.
+- **DNA absent** (deliberately parked — treat as open question, not a gap).
+
+**The biggest gaps vs OSS (GRAMPS / Gramps Web / webtrees).** These are where a privacy-first self-host product is expected to compete and currently trails:
+
+- **Collaboration is plumbed but unreachable.** `TreeMembership` roles are enforced on every read/write, but there is **no API or UI to invite, grant, change, or revoke** a member — the tree is effectively single-user despite multi-user infrastructure. This also breaks the full-CRUD invariant (NN#8) and, because importance and the old Phase-6 schedule disagree, a minimal management slice is pulled forward (§2.9).
+- **Living-person redaction is non-uniform.** Redaction is applied on person reads but **not** on the event/media/name/relationship/citation/source child-resource endpoints — a real PII leak on public/unlisted trees (NN#3, NN#2).
+- **`site_members` visibility tier is silently broken** (defined, selectable in UI, never handled in `can_view_tree`).
+- **No place as a usable first-class entity** (model exists, created by GEDCOM, but no read/edit/delete — a create-only entity, which is a bug per NN#8).
+- **No research log, to-do/task planner, kinship calculator, data-quality checker, or i18n/string externalization** (the last is a documented day-one commitment that is currently unmet).
+
+**Security-priority correctness fixes (do these first, regardless of phase).** Three current defects are user-harm or trust issues, not roadmap items:
+
+1. **Media privacy leak (§2.4)** — `list_media`/`get_media`/`media_content` gate on `can_view_tree` but never `person_visibility`; non-owners can download photos of redacted living people on public/unlisted trees.
+2. **Child-resource redaction gap (§2.10)** — event/media/name/relationship/citation/source endpoints don't apply living-person redaction.
+3. **Registration issues a live session before verification (§2.10)** — `register` returns an authenticated session cookie + token (201) and `email_verified_at` is written but never read on any path; there is no env switch to gate self-registration. The *enforcement check* (read-side `email_verified_at`) is small; the approval-mode env switch is the larger piece.
+
+**Strategic posture.** The differentiators worth pressing — property chain-of-title, the ChangeProposal AI model, the anonymous mutual-consent hint system, and true self-host data ownership — are mostly still ahead on the roadmap. The near-term job is (a) close the **privacy/auth correctness** and **collaboration** gaps that the architecture already implies, (b) ship the **maps + reports + merge** table stakes, and (c) build the **connector/ModelProvider/ChangeProposal** spine that unlocks the entire back half of the roadmap.

+## 2. Backlog by category

+### 2.1 Tree & data model
+
+Core CRUD, typed relationships, dates, soft-delete, and naming are **have**. Remaining work is about reusable sub-entities, shared/event-centric modeling, and research-grade conveniences.
+
+| Item | Description | Status | Imp | Eff | Phase | Non-negotiable |
+|---|---|---|---|---|---|---|
+| Repository as first-class entity | Promote `Source.repository` string to a reusable `Repository` (name/address/call-numbers) with dedup. | Partial | Med | M | 1–2 | If promoted, full CRUD in API+UI (NN#8) — don't half-build. |
+| Note as first-class entity (SNOTE) | Promote inline `notes` text fields to reusable shared `Note`/SNOTE records. | Missing | Low | M | 2 | Full CRUD; GEDCOM 7 round-trip parity. |
+| Shared/event-centric model + witnesses | Remove the `subject_person_xor_relationship` XOR; add participant/role join so one event has many people (FAN/cluster research). | Missing | Med | M | later | Unlocks FAN club + richer sourcing; participants must redact via privacy engine. |
+| Non-family associations (FAN) | Add associate/neighbor relationship types; best delivered with shared-event participants. | Missing | Low | M | later | — |
+| Relationship-status enum | Add married/divorced/annulled status on partnership rather than inferring from events. | Partial | High | M | 1–2 | — |
+| Family/couple unit (GEDCOM FAM) | Persist a true FAM entity (own ID/sources, childless couples) instead of rebuilding on export. | Partial | High | L | 2 | Improves GEDCOM fidelity. |
+| Kinship / relationship calculator | "How is A related to B" path + cousinship. Graph edges already exist. | Missing | High | M | 1–2 | Self-contained; reads via privacy engine. |
+| **Read-only audit-log viewer / activity feed** | Surface `AuditEntry` as a per-tree/per-person change feed. Smaller and higher-leverage than value-level undo; partially satisfies NN#8's "read" for AuditEntry and is the substrate for watch/follow + webhooks. | Missing | High | M | 2 | Privacy-filtered projections only — never raw before/after JSON to non-members (NN#2/#3). |
+| Per-field revision history + restore-prior-value | Value-level history view + undo, built atop the audit feed above. | Partial | High | L | 6 | Audit-log *UI* is the feed item; this is the larger value-level-undo work (NN#8 correction ethos). |
+| Color-coded tags & custom labels | Tag people for lineages/research-status/grouping. | Missing | Med | M | 2 | Full CRUD; tenant-scoped. |
+| Person timeline / LifeStory | Sort the merged event list; add place/age enrichment + narrative presentation. | Partial | Med | M | 2 | Sort is trivial (`localeCompare` on `date_start`); narrative is the larger piece. |
+| Multi-calendar normalization | Store + parse Julian/Hebrew/French Republican (only `calendar` tag stored today, only Gregorian normalized). | Partial | Low | M | 2 | See also Localization §2.17. |
+| Evidence/persona vs conclusion model | GEDCOM-X persona layer separate from conclusion person. | Missing | Med | XL | later | Large modeling change; strengthens sourcing + hint matching. |
+| Negative assertions | Boolean "event did not happen" on Event. | Missing | Low | S | 2 | Cheap interop nicety. |
+| Custom groups / networks | Named manual or rules-based groupings. | Missing | Low | M | later | Lower priority than tags. |
+| Raw GEDCOM record editor / configurable fact tabs | webtrees-style raw editor + fact-type registry. | Partial | Med | L | later | Open vocabularies give de-facto custom facts today. |
+| Health/medical, historical-facts index, LDS ordinances | Niche entities. | Missing | Low | M–L | later | LDS BAPL/ENDL/SLGS should map to distinct types if ever pursued; medical is special-category PII. |

+
+### 2.2 Sources & citations
+
+The two-tier model is **have** and production-grade on the backend. The gaps are almost all UI/CRUD-completeness and the connector-dependent "save to tree" flows.
+
+| Item | Description | Status | Imp | Eff | Phase | Non-negotiable |
+|---|---|---|---|---|---|---|
+| Citation confidence selector in UI | Confidence enum is modeled + API-writable but the `citeControl` form never sets it — every UI citation is NULL confidence. | Partial | High | S | 1 | **Quick win.** Full CRUD in UI (NN#8); reinforces evidence-quality thesis. |
+| Source edit UI + all 8 fields | Source UI is add/list/delete only and create exposes ~3 of 8 fields (no author/source_type/publication_info/quality_note/citation_text). | Partial | High | S | 1 | Update API exists but no edit form — violates NN#8. |
+| `GET /{tree}/citations/{id}` | Citation API has list but no single-read endpoint. | Partial | Med | S | 1 | API symmetry (NN#8). |
+| Transcription / abstract / extract fields | Add `transcription_text` + `abstract_text` to Source; don't conflate with `citation_text` (GEDCOM SOUR.TEXT currently dumped into citation_text). | Missing | Med | S | 1–2 | **Quick win.** Central to evidence analysis; full CRUD (NN#8). |
+| Evidence-Explained guided citation builder | Structured fields → formatted citation (Chicago/MLA/APA) instead of hand-typed `citation_text`. | Missing | High | L | 2 | Signature provenance feature; citation_text should be generated, not typed. |
+| Citations on OwnershipEvents | Add `ownership_event_id` to Citation + extend CHECK to 5 targets when property lands. | Partial | Critical | S | 3 | **Quick win once Property exists** — single FK + constraint edit (NN#5). |
+| Record-to-source attachment ("save to tree") | Search a connector record and attach its facts. | Missing | High | XL | 4 | Gated on connector framework; assistant attach must emit ChangeProposal (NN#1); legal sources only (NN#6). |
+| Source Linker (one record → many persons) | Bulk-attach a record's facts across people. | Missing | Med | L | 4 | Downstream of connectors; reads/writes via service layer. |
+| Auto-citation on save/match | Generate citation when a hint/record is confirmed. | Missing | Med | L | 4/7 | Blocked on connectors + hints; ChangeProposal if assistant-driven. |
+| Memories-as-sources (cite a photo directly) | Allow media to be a citation target, not only attachable to a Source. | Partial | Low | M | 2 | Reads stay on privacy-checked media endpoint (NN#2). |
+| GPS / Proof-Standard reasoning artifact | Container linking sources/citations into a proof narrative reconciling conflicts. | Missing | Med | L | later | Serious-researcher differentiator; full CRUD (NN#8). |
+| Proprietary record collections | 1921 census, UK sets, etc. | Missing | Low | XL | — | **Out of scope** — conflicts with NN#6 / self-host. Do not pursue. |
+
+---
+
+### 2.3 Search & matching
+
+Fuzzy trigram name search is **have**; everything that depends on connectors, embeddings, or multiple populated trees is planned/missing. The standout near-term gap is **in-tree person merge**.
+
+| Item | Description | Status | Imp | Eff | Phase | Non-negotiable |
+|---|---|---|---|---|---|---|
+| Standalone duplicate detection | Lift the GEDCOM `_best_match` logic into a "find duplicates in my tree" scan. | Partial | High | M | 2 | Logic already written; results via privacy engine (NN#2). |
+| Interactive two-person merge (side-by-side, field-select, undo) | General merge of duplicate persons with citation re-pointing — impossible outside import today. | Partial | High | L | 2 | **Highest-value matching gap.** Preserve + re-point Citations (NN#5); write-once is a bug (NN#8). |
+| Advanced search (wildcards, boolean, date/place facets, sort) | Search exposes only `?q`. | Partial | High | M | 2 | Keep per-person privacy filter in the search loop (NN#2). |
+| Phonetic matching (Soundex/Metaphone/DM) | Enable `fuzzystrmatch`; trigram is char-similarity, not phonetic. | Partial | High | M | 2 | Pure utility. |
+| Semantic / vector search (pgvector) | **Docs claim pgvector is used; it is not** — only pg_trgm extension is created. Add `CREATE EXTENSION vector` + embedding columns (and correct the docs). | Missing | Med | L | 7 | Embedding provider is an open question (PRD §11) — don't pick silently; candidates via privacy engine. |
+| Tree-to-tree matching (Smart Matches) | Cross-tree candidate generation + ranking. | Planned | High | XL | 7 | Anonymous until mutual consent (NN#4); living-person protection (NN#3). |
+| Mutual-consent match notification | Anonymous notification, reveal only after both opt in. | Planned | High | L | 7 | **Mandated invariant**, not a toggle (NN#4, NN#3); rides the notification substrate (§2.9). |
+| Match confirm/reject + "not a match" memory | Persistent rejected-match store (today scoring lives only inside import). | Partial | High | M | 7 | Prevents re-notifying once hints land. |
+| External search deep-links | Pre-fill FamilySearch/Find A Grave/BLM-GLO search URLs from a person's name/dates/place. | Missing | Med | M | 2–4 | **High value, low risk** before full connectors; legal targets only (NN#6). |
+| **Automated record hints** | Proactive per-person record suggestions from connectors — a marquee mainstream feature. | Missing | High | XL | 7 | Connector-gated (NN#6); surfaced anonymously where cross-tree (NN#4); attach via ChangeProposal (NN#1). |
+| Jurisdiction-aware record-search hints | Map place/jurisdiction → relevant collections. Place hierarchy is a ready foundation. | Missing | Med | L | 8 | Suggested collections must be legal (NN#6). |
+| Cross-language / transliteration matching | Cyrillic/Hebrew/CJK ↔ Latin. | Missing | Med | XL | later | See Localization. |
+| Record Detective, newspaper matches, collection catalog, GQL query builder, OCR full-text search | Connector/record-layer dependent. | Missing/Planned | Low–Med | L–XL | 4/7/8 | All gated on the connector framework; any query path runs through privacy engine (NN#2). |
+
+---
+
+### 2.4 Media & documents
+
+Universal media attachment is **have**, but with a **confirmed privacy leak** and no asset-processing pipeline.
+
+| Item | Description | Status | Imp | Eff | Phase | Non-negotiable |
+|---|---|---|---|---|---|---|
+| **Media privacy gating on serve paths** | `list_media`/`get_media`/`media_content` gate only on `can_view_tree`, never `person_visibility` — a non-owner can download photos of redacted living people on public/unlisted trees. | Have(leaky) | **Critical** | M | 1 | **Security-priority — fix first. Direct NN#3/NN#2 violation.** Check attached `person_id` visibility and redact/hide. |
+| EXIF / GPS stripping on upload | Raw bytes stored verbatim; family photos leak GPS/home addresses/timestamps. | Planned | High | M | 1 | **Security-priority**, not cosmetic. Parse EXIF on ingest, strip/quarantine by default, allow override. |
+| Thumbnail / preview generation | No image pipeline (no Pillow). Async, idempotent worker job. | Planned | High | L | 1 | Derived thumbnail must inherit parent privacy — no bypass path. |
+| Image reference regions | Mark the rectangle of a census image that supports a Citation. | Missing | Med | M | later | Tenant-scoped, full CRUD; region→Citation preferred over region→Person. |
+| Photo/face tagging (manual) | Multi-person tagging via single FK today. | Missing | Med | XL(ML)/M(manual) | later | Owner-only, in-deployment; face tags inherit redaction (NN#3); full CRUD. |
+| Mobile photo scanning + auto-split | Shoebox digitization. | Missing | Med | L | later | Reuse privacy-gated upload + EXIF strip. |
+| AI photo dating / colorize / restore / animate / narrate | Model-driven media features. | Missing | Low | L–XL | 4+ | Must route through ModelProvider (NN#7), require approval (NN#1), preserve original; animating living faces raises consent issues. |
+| British Library / paywalled archives, pay-per-view credits | Licensed content + metering. | Missing | Low | XL | — | **Out of scope** — conflicts with NN#6 and the self-host model. |
+
+---
+
+### 2.5 DNA & genetic genealogy
+
+DNA is an **explicit PRD non-goal / open question** — treat as parked, not a backlog to grind through. Across every DNA row the rule is uniform: **a user uploading their own export is permissible; vendor connectors/scrapers (23andMe / Ancestry / MyHeritage / GEDmatch) are barred (NN#6).** Kits and matches are living-tester PII and route through the privacy engine.
+
+| Item | Description | Status | Imp | Eff | Phase | Non-negotiable |
+|---|---|---|---|---|---|---|
+| DNA-confirmed relationship flag | Model DNA confirmation as a Source/Citation backing a Relationship (not free text). | Missing | Med | M | parked | Best sources-first fit (NN#5); full CRUD (NN#8). |
+| Raw DNA upload (own file) | User uploads own export; no vendor scraping. | Missing | Med | L | parked | User's own file is fine; vendor connectors barred (NN#6); special-category PII via privacy engine. |
+| Kit/Match entities linked to persons | Kit (tester) + Match tied to Person, tenant-scoped/audited. | Missing | Med | M | parked | Kits = living-tester PII (NN#2/#3); full CRUD (NN#8). |
+| Autosomal match list, segments, chromosome browser, triangulation, ThruLines/AutoTree, ethnicity/admixture, haplogroups, GEDmatch, NPE detection | Full genetic-genealogy suite. | Missing | Low–Med | L–XL | parked | DNA scope is an unresolved open question — **surface the dependency, don't build speculatively.** Own-data only (NN#6); cross-user surfacing obeys NN#4. |
+
+---
+
+### 2.6 Maps, places & gazetteers
+
+This category is almost entirely **missing** despite being half the product thesis. The Place model has the right bones (parent_id, lat/long, PlaceName with date ranges) but no API/UI and no maps.
+
+| Item | Description | Status | Imp | Eff | Phase | Non-negotiable |
+|---|---|---|---|---|---|---|
+| **Place as usable first-class entity** | Place rows are created by GEDCOM but have **no read/edit/delete** API or UI — a create-only entity. | Partial | High | M | 2–3 | **Violates NN#8** (create-but-not-edit = bug). Make Place citable too (NN#5). |
+| Place autocomplete + picker in event editor | No `/places` router; the event form has no place input, so users can't attach a place at all. | Missing | High | M | 2 | Table stakes; lookup is low-risk. |
+| Geocoding (manual coords + forward) | lat/long columns exist; no UI, no geocoder. | Partial | High | M | 3 | Provider via env (NN#7), ToS-compliant (NN#6). |
+| Pluggable geocoding provider | Nominatim/GeoNames/Bing/Google swappable. | Missing | Med | L | 3 | Provider+keys via env (NN#7); legal providers only (NN#6). |
+| Bulk/batch geocoding (worker) | Geocode hundreds of GEDCOM-imported places. | Missing | Med | M | 3 | Idempotent, rate-limited worker job; provider via env. |
+| Place merge/split (dedup) | GEDCOM imports produce near-duplicate place strings. | Missing | High | M | 2–3 | Needs Place update/delete (NN#8); audited merges. |
+| Place-name cleanup tools | Extend the existing preview→apply cleanup UX to places. | Missing | Med | M | 2 | Preview-first + audited like existing cleanup. |
+| Standardized-name vs original text | Mirror the verbatim+normalized date pattern for places. | Missing | Med | M | 2–3 | GEDCOM fidelity. |
+| Alternate/historical place names with date ranges | `PlaceName` model exists with valid_from/to but no CRUD and never populated. | Partial | Med | M | 2–3 | Stored entity with no CRUD surface (NN#8). |
+| Interactive map of events & places | No map library in frontend. Core to family+land positioning. | Missing | High | L | 3 | Plot via `person_visibility` so non-owners never see living locations (NN#2/#3). |
+| Migration trail / pedigree-birthplace maps | Per-person life path; ancestor birthplace map. | Missing | Med | L | 3 | Redact living subjects for non-owners (NN#3). |
+| Bundled world gazetteer | Offline GeoNames-style authority. | Missing | Med | XL | later | GeoNames (CC-BY) verify AGPL-compat; env-configurable. |
+| Historical boundary overlays, time slider, heatmaps, radius/nearby, tile-provider switch | Advanced geo. | Missing | Low–Med | S–XL | later | PostGIS is an open question (ARCH §14) — **surface dependency**, don't adopt silently; tiles legal (NN#6). |
+
+---
+
+### 2.7 Charts, reports & printing
+
+On-screen pedigree/descendant/fan/hourglass charts are **have**. The entire **output/print/report** half is missing — this is the linchpin gap of the category.
+
+| Item | Description | Status | Imp | Eff | Phase | Non-negotiable |
+|---|---|---|---|---|---|---|
+| **Multi-format export (PDF / SVG / image / HTML)** | No export/print path, no `@media print`, no `window.print()`. Charts and reports can't leave the screen. | Missing | High | L | 2/6 | **Linchpin.** Generate from privacy-filtered data so living people redacted in shared output (NN#3). |
+| Ahnentafel report | Numbered-ancestor report; all data exists. | Missing | High | M | 6 | — |
+| Family group sheet / individual summary | Printable summary; data available, needs print layout. | Missing | High | M | 6 | — |
+| Narrative descendant/ancestor reports | Multi-standard prose with inline sources. | Missing | High | L | 6 | Cite Sources inline (NN#5); redact living (NN#3). |
+| Sentence-template narrative engine | Deterministic fact→prose underpinning reports. | Missing | Med | L | 6 | Keep template-based; report text never mutates tree (NN#1). |
+| Photo boxes in charts | Pass privacy-checked media URLs to `setCardDisplay`; CSS already present. | Missing | High | M | 2 | Stream via privacy-checked /media (NN#2/#3). |
+| Drag-to-edit / interactive chart canvas | Tree canvas renders but interactive node editing (drag to re-parent, inline edit on the chart) is only partly present. | Partial | Med | M | 2 | Edits go through service layer + audit (NN#1); honor redaction. |
+| Statistics dashboard | Surname/place/date distributions + tree-health. | Missing | Med | M | 6 | Reads via privacy engine (NN#2). |
+| Kinship/relationship diagram report | Needs path-finding (see §2.3 calculator) + renderer. | Missing | Med | M | 6 | — |
+| List reports (sources/places/repos/media) | Printable indexes (current screens are management, not reports). | Missing | Med | M | 6 | — |
+| Color-by-lineage, fan overlays, lifespan/timeline charts | Sex-coloring exists; lineage/overlay/timeline don't. | Partial/Missing | Med | M | later | Overlays respect privacy engine. |
+| Book/multi-report compiler, wall-chart tiling, page-setup, customizable charts | Print-shop-grade output. | Missing | Low–Med | L–XL | later | Saved "book" entity = full CRUD (NN#8); honor living-person privacy. |
+| Bowtie/couple-rooted/circular-sun/3D/network/calendar | Niche chart variants. | Missing/Partial | Low–Med | M–L | later | — |
+| Print-shop products, XML template engine, blank forms | Commercial/template extras. | Missing | Low | S–XL | later | Weak fit for self-host. |
+
+---
+
+### 2.8 Research workflow & automation
+
+The preview→approve **bulk cleanup** tool is a genuine **have** and a differentiator. The missing pieces are the serious-researcher workflow entities.
+
+| Item | Description | Status | Imp | Eff | Phase | Non-negotiable |
+|---|---|---|---|---|---|---|
+| Data-quality / consistency checker | Extend cleanup beyond name issues: child-before-parent, death-before-birth, implausible ages, orphans, dups; severity tiers. | Partial | High | L | 2 | New auto-fixes keep preview→apply (NN#1). |
+| Research log | Searches, repositories visited, negative results, findings — distinct from the system audit log. | Missing | High | M | 6 | Reference reusable Sources (NN#5); tenant-scoped full CRUD (NN#8). |
+| To-do / research task planner | Tasks on Person/Tree with status/priority/due/assignment. | Missing | High | M | 6 | Full CRUD in API+UI (NN#8). |
+| Source-driven data entry | Start from a Source document and transcribe facts into the tree. | Missing | High | M | 2 | Natural sources-first differentiator (NN#5). |
+| Task↔log linkage | FK + joined view once both entities exist. | Missing | Med | S | 6 | Cheap once predecessors land. |
+| Family chronology / timeline | Sort merged events; family-wide chronology (parents' marriage, siblings' births). | Partial | Med | M | 2 | Sort is trivial; presentation over privacy-filtered data. |
+| Navigation: active person / history / bookmarks | Large trees rely on browser back only. | Missing | Med | M | 2 | Per-user, tenant-scoped, full CRUD; don't expose redacted persons (NN#2/#3). |
+| Saved-record shoebox / review queue | Stage candidate records before committing. | Missing | Med | M | 4/7 | Auto-attach via ChangeProposal (NN#1); legal sources (NN#6). |
+| Guided research suggestions | Proactive "research next" engine (today only flags problems). | Partial | High | L | 4 | Advisory; writes via ChangeProposal (NN#1); cross-tree via privacy engine (NN#2). |
+| Persona-adaptive onboarding | Family Keeper / Serious Researcher / Property Researcher selector (PRD US-002, documented but unbuilt). | Missing | Low–Med | L | 2 | Pure presentation. |
+| Dashboard widgets, scratchpad, research-link sidebar, blog/narrative authoring, research wiki, crowd indexing | Conveniences. | Missing | Low | S–XL | later | Widgets/published narratives read via privacy engine (NN#2/#3). |
+
+---
+
+### 2.9 Collaboration & sharing
+
+Authorization is enforced everywhere, but the **management surface is entirely absent** — the most consequential gap relative to the multi-user product promise. Because the Critical items below previously sat at Phase 6 while their labels said "breaks NN#8," a minimal management slice is pulled forward to Phase 2; the richer invite/email UX stays at Phase 6.
+
+| Item | Description | Status | Imp | Eff | Phase | Non-negotiable |
+|---|---|---|---|---|---|---|
+| **Membership PATCH/DELETE + role change (minimal slice)** | Add/adjust/revoke a collaborator and change `role` — the substrate (mutable `role`) exists; only the endpoints are missing. Resolves the create-only NN#8 break without the full invite flow. | Partial | **Critical** | S–M | 2 | **Pulled forward** — a create-only entity shouldn't wait for Phase 6 (NN#8). Revocation routes through the single privacy point. |
+| Full invite/grant flow (email + UI) | Email-based invitations, pending-invite state, role-grant UI, resend/expire. Builds on the minimal slice. | Partial | High | L | 6 | Invitation email via configured SMTP (NN#7); membership changes through the one enforcement point. |
+| **Read-only public tree share** | Visibility model already redacts living persons for anonymous viewers, but every endpoint requires `CurrentUser` — no optional-auth dep, no public route, no public page. | Partial | High | M | 2 | Highest-leverage near-term sharing feature; living-safe by construction via `person_visibility` (NN#2/#3). |
+| SEO public profile pages (server-rendered) | Intent declared (`public` = search-indexable) but zero implementation; no sitemap/robots/meta. | Partial | Med | L | 2 | NN#2 explicitly names server-rendered public pages — must go through privacy engine, no direct row queries. |
+| **Notification / event-dispatch substrate** | Shared enabler seeded from `AuditEntry`: subscription + dispatch layer emitting privacy-filtered projections. Underpins watch/follow, mutual-consent match notices, comments, moderation, and in-app messaging. | Missing | High | L | 6 | **Privacy-filtered projections only — never raw before/after JSON** (NN#2/#3). |
+| Comments / discussion threads | Per-profile discussion (target = person/event/source), threaded. | Missing | High | M | 6 | Comments on living persons redacted for non-members (NN#2/#3); rides the dispatch substrate. |
+| In-app messaging (contact details hidden) | SMTP exists; no Message/Thread model. | Planned | High | L | 6 | Hide contact details; opens after mutual consent (NN#4); redact living-person content; rides dispatch substrate. |
+| Watch/follow + change notifications | `AuditEntry` is the natural event source; needs subscription entity + dispatch (substrate above). | Planned | Med | M | 6 | Notification builder reads via privacy engine, not raw rows. |
+| **Optimistic concurrency / lost-update protection** | No version/etag/`updated_at` precondition checks; concurrent multi-user edits can silently clobber. | Missing | High | M | 6 | Full-CRUD + multi-user without this risks lost updates; concurrent paths still route through privacy engine. |
+| Pending-changes moderation (human edits) | Queue contributor edits for owner approval — shares infra with the AI ChangeProposal queue. | Missing | Med | L | 6 | **Design together with ChangeProposal** (NN#1). |
+| Field-by-field profile merge & approval | WikiTree-style merge center + unmerge with per-field provenance. | Missing | Med | XL | later | Conflicting facts each retain Source/Citation (NN#5). |
+| Ownership transfer | `owner_id` is effectively write-once; needed for self-host longevity. A minimal reassignment endpoint is the NN#8 fix. | Missing | Med | M | 6 | **Violates write-once invariant** (NN#8) — importance/phase tension noted; ship the minimal slice when membership lands. |
+| Narrative website / HTML export | Static narrated site (reuse public-page renderer). | Missing | Med | L | later | Redact living persons at build time (static bypasses runtime engine) (NN#3). |
+| Two-way desktop↔online sync | Bidirectional sync with change journals. Audit log could seed a change feed. | Missing | Med | XL | later | No Ancestry TreeShare / paywalled sync (NN#6). |
+| Curator roles, trusted-list ACLs, field locking, projects/workspaces, forum, honor code, free-space wiki, portal homepage | Community-platform features. | Missing | Low | S–XL | later | New roles/ACLs/locks integrate with the **single** enforcement point, not parallel checks. |
+| Real-time co-editing | Out of scope; only optimistic concurrency planned. | Planned | Med | XL | later | Concurrent paths must route through privacy engine. |
+
+---
+
+### 2.10 Privacy & access control
+
+The architecture is correct (single engine, tenant mixin, audit, soft-delete + purge are **have**), but enforcement coverage and configurability have real holes — two of which are security-priority.
+
+| Item | Description | Status | Imp | Eff | Phase | Non-negotiable |
+|---|---|---|---|---|---|---|
+| **Uniform living-person redaction across child resources** | `_redact` runs on person reads but **not** on event/media/name/relationship/citation/source endpoints — non-members fetch a possibly-living person's events/photos/names directly. | Partial | **Critical** | M | 1–2 | **Security-priority. Core NN#3/NN#2 defect.** Apply `person_visibility` on every person-derived fact. |
+| **Email-verification enforcement gate** | `email_verified_at` is written at `auth_service.py:154` but read on no path; `register` returns an authenticated session cookie + token (201) pre-verification. | Partial | **High** | S | 1–2 | **Security-priority near-quick-win** — add the read-side check (NN#7 trust path). The check is small; the registration-mode switch below is the larger piece. |
+| Self-registration mode gating (approve / open / closed) | No env switch to choose open vs admin-approval vs closed registration. | Partial | High | M | 2/5 | Twelve-factor registration control (NN#7); pairs with the verification gate above. |
+| **Fix `site_members` visibility tier** | Defined + selectable in UI but `can_view_tree` only handles public/unlisted — fails closed unintuitively. | Partial | Critical | S | 1 | **Quick win.** Least-surprise; honor the tier the UI offers. |
+| Make `LIVING_RECENCY_YEARS` configurable | Hardcoded 100 at `privacy.py:23`. | Partial | High | S | 2 | **Quick win.** Twelve-factor (NN#7). |
+| Privacy-stripped export (redact living) | GEDCOM + account export emit full tree; no "strip living" mode. | Missing | High | M | 2 | Reuse `person_visibility`/`_redact` (NN#3). Owner self-export is safe today; shareable variant is the gap. |
+| Per-fact / per-field privacy + record flags | tentative/rejected/preferred/private flags on facts. | Missing | Med | L | later | If added, route through the single engine (NN#2). |
+| Granular rules by record type & viewer relationship | webtrees-style "hide marriages from non-descendants". | Missing | Med | L | later | Single enforcement point. |
+| OIDC / external IdP login | `AuthProvider` interface ready; only Local implemented. Authentik is the intended real auth. | Planned | High | L | 5 | Additive by design. |
+| Two-factor auth (TOTP) | Bearer/cookie session auth is solid; no MFA. | Partial | High | L | 5 | — |
+| DB-level audit immutability | Audit is insert-only by convention; no trigger/constraint. Verified as "adequate for self-host," so importance downgraded to match. | Have(soft) | Med | S | 9 | Adequate for self-host; upgrade to trigger only if true immutability is required. |
+| Block/hide users, family-group private space, DNA opt-in controls | Depend on messaging/DNA. | Missing | Low–Med | M–XL | 6/parked | DNA parked (NN#6). |

+
+### 2.11 Import/export & standards
+
+GEDCOM 5.5.1 import/export and full data-portability export are **have**, but fidelity gaps directly undercut the provenance thesis — and one is outright data loss.
+
+| Item | Description | Status | Imp | Eff | Phase | Non-negotiable |
+|---|---|---|---|---|---|---|
+| **Citation links dropped on GEDCOM export** | Export never selects the Citation table — fact→source links, page, detail, confidence all dropped on export (they import fine). Re-importing your own export **destroys** the sources-first graph. | Partial | **Critical** | M | 2 | **Silent data loss on the product's signature data + destructive round-trip** (NN#5); breaks PRD US-013. |
+| GEDCOM 7.0 import/export | Version hardcoded `5.5.1`; no v7 semantics, SCHMA, SUBM, or UID handling. | Partial | High | L | 2 | Stated differentiator (FamilySearch interop). |
+| Custom/underscore tag preservation | `_MARNM` becomes `TYPE married`, other custom tags dropped — violates ≥99% round-trip goal. | Missing | High | L | 2 | Tension with provenance thesis (faithful record). |
+| PLAC FORM hierarchy + MAP coordinate round-trip | Import reads only PLAC text; export emits flat PLAC. lat/long + hierarchy lost on round-trip. | Missing | High | M | 2–3 | Round-trip fidelity for the land/maps pillar. |
+| Encoding detection (ANSEL/UTF-16) | UTF-8 round-trips; non-UTF-8 files silently mangled via `errors='replace'`; CHAR tag ignored. | Partial | High | S | 2 | **Near quick win.** Detect/honor CHAR; reject or transcode rather than corrupt. |
+| HEAD completeness | HEAD at `gedcom.py:740` emits only `SOUR/GEDC/VERS/CHAR` — missing required `2 FORM LINEAGE-LINKED` (under GEDC) and `1 SUBM`. | Partial | Med | S | 2 | **Quick win.** Pure conformance. |

+### 2.12 Mobile & offline
+
+Responsive web is **partial**; PWA and offline-first are absent. Native apps are an explicit deferral.
+
+| Item | Description | Status | Imp | Eff | Phase | Non-negotiable |
+|---|---|---|---|---|---|---|
+| PWA (manifest + icons + viewport + service worker) | No manifest, no SW, no `next-pwa`; responsive coverage exists but unaudited on heavy views (tree canvas fixed 74vh). | Partial | High | M | 2 | If SW caches API responses, never retain non-owner PII; cache only what the session is authorized to see (NN#3). |
+| Responsive parity audit | 17 breakpoint usages; small-screen parity on tree/person views unverified. | Partial | High | M | 1–2 | Feature parity is an ARCH requirement. |
+| Offline-first editing + reconnect sync | No SW, no local store, no mutation queue. Valuable for archive/courthouse field research. | Missing | High | XL | later | Replayed edits go through service layer + audit (NN#1); cached data respects living-person rule (NN#3). |
+| Native mobile apps | Explicitly deferred (responsive web only). | Missing | Med | XL | later | If built, reads through one backend privacy engine (NN#2/#3/#4). |
+| Companion app w/ cross-device sync | Largely redundant with server-backed web. | Missing | Low | XL | later | Sync boundary enforces privacy (NN#2); full CRUD parity (NN#8). |

+### 2.13 API & extensibility
+
+Internal REST + OpenAPI + generated TS client are **have**. The externalized developer story and the connector/plugin spine are not built.
+
+| Item | Description | Status | Imp | Eff | Phase | Non-negotiable |
+|---|---|---|---|---|---|---|
+| Public read-only API + scoped tokens (OAuth) | Bearer token is opaque session only; `TokenPurpose` lacks scopes; designed `public.py` never built. | Partial | High | L | 5–6 | Any scoped-token path routes through `person_visibility` + living-person redaction (NN#2/#3). |
+| SourceConnector framework | Only AuthProvider/ObjectStore/Mailer base classes exist; no connector base/loader/registry. Gates AI, hints, property connectors. | Planned | Med | L | 4 | Read-only, rate-limited; findings via ChangeProposal (NN#1); legal sources only (NN#6). |
+| Webhooks / change feeds | `AuditEntry` is the natural substrate (shares the notification dispatch layer, §2.9); no feed/webhook layer. | Missing | Med | L | 6 | Emit privacy-filtered, tenant-scoped projections — never raw before/after JSON (NN#2/#3). |
+| CLI / scripting surface | No `[project.scripts]`, no Typer/Click; worker is a purge loop only. Self-hosters want bulk admin. | Missing | Med | M | 9 | Funnel reads through privacy.py, writes through audit; admin-scoped, no assistant-write path. |
+| Plugin/addon architecture | Connector framework only; no general UI/report/theme plugin system planned. | Planned | Med | L | later | Sandbox via service layer; no privacy/audit bypass, no writes outside ChangeProposal. |

+### 2.14 Performance & scale
+
+Postgres + S3, multi-tenant isolation are **have**. Queue, observability, backups, pagination, and scale validation are the gaps that gate Phases 4/7 — several are current functional limitations, not late-phase validation tasks.
+
+| Item | Description | Status | Imp | Eff | Phase | Non-negotiable |
+|---|---|---|---|---|---|---|
+| Real job queue (Postgres/Redis-backed) | Worker is a fixed-interval purge loop; GEDCOM import and account export run **inline in the request**. | Partial | High | L | 4 (pre-req) | Blocks NN#1 (assistant in worker) and NN#4 (hint matching in worker). Queue backend is an open question (PRD §11). |
+| **Pagination on list endpoints + server-side tree loading** | List endpoints (`persons.py:37`, events, relationships) take no `limit/offset/skip`; the tree view loads the whole graph client-side. A *current* limitation against the 50k-person target. | Planned | High | M | 1–2 | **Split out from scale validation** — this is a correctness/functional gap now, not a Phase 9 task. |
+| Scale validation (50k+ trees, P95<2s, load test) | No benchmark or load test exists. | Planned | High | L | 9 | Inline heavy ops risk partial writes — moving to the queue is what makes "failures never corrupt state" true. |
+| **Operator backup: one-command `pg_dump` + MinIO sync** | Only a documented procedure + per-account ZIP exist; no scripted DB+object dump. For a self-host product this is day-one data-loss exposure. | Partial | Critical | M | 1–2 | **Pulled forward** — Critical importance contradicted the old Phase-9 slot. Restore must re-apply privacy state faithfully (NN#3); safety net for NN#8. |
+| Scheduled / cloud automated backup + restore tooling | Cron-driven, off-host, verified-restore workflow. | Partial | High | L | 9 | Builds on the one-command slice above. |
+| ARM64 build matrix | CI builds `linux/amd64` only; many self-hosters run ARM SBCs. | Partial | High | S | 1 | **Quick win.** Add arm64 + QEMU to buildx (NN#7 container-native). |
+| Structured JSON logs + Prometheus metrics | Plain-text stdlib logging; no `/metrics`. | Partial | Med | M | 9 | Logs/metrics reference UUIDs, never names/PII (NN#3/#4). |
+| pgvector enablement | Image has pgvector; app never creates the extension or adds embedding columns (docs claim otherwise). | Partial | Med | M | 7 | See §2.3 — embedding provider open question; candidates via privacy engine. |
+| Database check-and-repair | No orphan/dangling-edge/cycle scanner (recent "harden tree render" commit shows bad graphs occur). | Missing | Med | M | 9 | Tenant-scoped + audited; auto-fix via ChangeProposal (NN#1). |
+| Pluggable DB backend, billions-scale shared tree, weekly record releases | Different product models. | Missing | Low | XL | — | **Out of scope** — Postgres-only is consistent with the invariants; global shared tree conflicts with NN#2/#3/#4. |

+### 2.16 AI assistant — *defining differentiator*
+
+Entirely **planned** — and note the docs-vs-code gap: ARCHITECTURE §5 lists `ChangeProposal` as part of the "landed" core model, but no model/migration/schema exists. The audit substrate (`actor_type=assistant`, before/after JSONB) is the right foundation; the ChangeProposal model and ModelProvider abstraction are the two critical-path pieces.
+
+| Item | Description | Status | Imp | Eff | Phase | Non-negotiable |
+|---|---|---|---|---|---|---|
+| **ChangeProposal (propose-then-confirm)** | The defining invariant. No `proposal.py`, no migration, no review UI yet — despite docs implying it landed. | Planned | **Critical** | L | 4 | **IS NN#1.** Enforce structurally: assistant tools return proposals; only user action applies one; application flows through the normal service layer (privacy + audit). ChangeProposal itself needs full CRUD (NN#8). Correct the docs to match reality. |
+| Pluggable LLM + embedding provider | `ModelProvider` over Anthropic/OpenAI/xAI/Ollama; env placeholders exist, no interface code. | Planned | Critical | M | 4 | **Twelve-factor, no hard-coded keys/endpoints** (NN#7); the Ollama/self-hosted path is what makes the privacy-first promise real. |

+
+### 2.17 Localization & accessibility
+
+A documented **day-one commitment** ("UI strings externalized from day one") that is currently **unmet** — every label is a hardcoded literal. Correct the PRD claim or close the gap.
+
+| Item | Description | Status | Imp | Eff | Phase | Non-negotiable |
+|---|---|---|---|---|---|---|

+| Multi-language UI (40–60+ langs) | Translation pipeline after externalization (frontend + backend-generated messages). | Missing | High | XL | later | Table stakes across all competitors. |
+| Accessibility / WCAG 2.2 AA | Some ARIA/focus styling; no CI a11y audit, no skip-links, SVG tree viz not keyboard/screen-reader navigable. | Partial | High | L | 2/9 | Stated PRD §6 target; add axe/pa11y in CI; accessible alternate to the chart. |
+| Unicode-correct non-Latin names | Stores fine (UTF-8); no NFC normalization on write, no locale-aware collation, no romanized search. | Partial | High | M | 2 | Apply `unicodedata.normalize('NFC')` on input; add COLLATE; supports faithful-record goal. |

+---
+
+## 3. Quick wins (high importance / low effort)
+
+Ordered by leverage. All are S-effort or a thin slice of a larger item, and most close a stated invariant gap.
+
+1. **Fix `site_members` visibility tier** (Privacy, Critical/S) — defined and selectable in the UI but never handled in `can_view_tree`; fails closed unintuitively.
+2. **Email-verification enforcement gate** (Privacy/Auth, High/S) — add the read-side `email_verified_at` check so a freshly registered, unverified user doesn't get a live authenticated session. Security-priority; the registration-mode env switch (open/approve/closed) is the larger follow-on, not part of this quick win.
+3. **Citation confidence selector in the cite form** (Sources, High/S) — confidence is modeled and API-writable but unreachable in the UI; every UI citation is currently NULL. Honors NN#8 and the evidence-quality thesis.
+4. **Source edit UI + expose all 8 fields** (Sources, High/S) — update API exists but there is no edit form and create exposes ~3 fields; a create-but-not-edit entity violates NN#8.
+5. **Make `LIVING_RECENCY_YEARS` env-configurable** (Privacy, High/S) — hardcoded 100 at `privacy.py:23`; twelve-factor (NN#7).
+6. **Add `ownership_event_id` to Citation** (Property/Sources, Critical/S) — single FK + CHECK-constraint edit the moment Property lands; the spine is already built (NN#5).
+7. **GEDCOM encoding detection** (Standards, High/S) — detect/honor the CHAR tag; reject or transcode ANSEL/UTF-16 rather than silently mangling with `errors='replace'`.
+8. **GEDCOM HEAD completeness** (Standards, Med/S) — emit the required `2 FORM LINEAGE-LINKED` (under GEDC) and `1 SUBM` at `gedcom.py:740`. Pure conformance.
+9. **ARM64 CI build matrix** (Perf/Scale, High/S) — add `linux/arm64` + QEMU to buildx for both images; many self-hosters run ARM SBCs.
+10. **`GET /{tree}/citations/{id}` endpoint** (Sources, Med/S) — API symmetry (NN#8).
+11. **Transcription/abstract fields on Source** (Sources, Med/S) — add `transcription_text` + `abstract_text`, distinct from `citation_text`; core to evidence analysis.
+12. **Sort the merged person timeline** (Research workflow, Med/S) — `shownEvents.sort()` on `date_start`; currently appended unsorted.
+13. **Doc corrections (docs-vs-code)** (Meta, trivial/S) — edit CLAUDE.md / ARCHITECTURE so the pgvector "used" claim, the i18n "from day one" claim, and the ChangeProposal "landed" claim match reality. The repo convention requires docs to travel with code.
+
+> **Ships-with, not standalone:** *Revocable / adjustable access (membership PATCH/DELETE + role change)* is security-critical and S-effort, but it is the minimal slice of the membership work (§2.9) and ships **with** those endpoints — it is not independently shippable on its own.
+>
+> **Higher priority than any quick win, but M-effort (not quick):** the **media privacy leak** (§2.4), the **child-resource redaction gap** (§2.10), and pulling the **one-command operator backup** (§2.14) forward. Treat these as **security-/data-loss-priority Phase 1–2 fixes** regardless of the quick-win list.
+
+---
+
+## 4. Strategic differentiators
+
+Where to invest to make Provenance distinct rather than a webtrees clone. Each leans on a non-negotiable as a *feature*, not a constraint.
+
+**1. Property chain-of-title (the "land" half).** No surveyed competitor models ownership as a typed, cited event chain tying parties across time, with gap-flagging and bidirectional owner↔person / parcel↔place traversal, fed by **legal** public sources (BLM/GLO patents, USGS, public county deeds). This is the single clearest "no one else does this" capability. Sequence: Property + OwnershipEvent + Citation-target (Phase 3) → chain-of-title view → BLM/GLO connector (Phase 8). The Citation extension is a quick win; the entity is the prerequisite for everything else in the category.
+
+**2. The ChangeProposal AI model.** "The assistant never writes autonomously" is a *trust* differentiator in a market where users fear AI corrupting their research. Build it structurally — assistant tools return proposals; only an explicit human action applies one; application flows through the normal service layer so it always hits the privacy engine and audit log. The same approval queue moderates untrusted human-contributor edits (Collaboration §2.9), so design them together. The audit substrate is already in place; ChangeProposal + ModelProvider are the critical path — and the docs should stop asserting ChangeProposal has landed until it has.
+
+**3. Anonymous, mutual-consent cross-tree hints.** The privacy model already redacts living people for anonymous viewers, so a hint system that reveals *nothing identifying* until both sides opt in is achievable by construction — and is a categorically more trustworthy version of MyHeritage Smart Matches / Ancestry hints. Requires the matching engine (pgvector enablement + candidate generation, Phase 7), the notification/event-dispatch substrate (§2.9), and the messaging channel that opens only post-consent.
+
+**4. True self-hosting + data ownership.** Full account export/import, soft-delete recovery, GEDCOM round-trip, env-driven everything, and (to-build) operator-grade scheduled backup + ARM support make Provenance the genealogy app you actually own. Two correctness items gate the promise: GEDCOM export must stop dropping citations (a Provenance→Provenance round-trip currently destroys the sources graph), and operator backup must move from "documented procedure" to a one-command dump. The Ollama/self-hosted ModelProvider path means even the AI assistant runs without tree data leaving the deployment — a promise no commercial competitor can make.
+
+**5. Sources-first as a felt experience.** The two-tier model is built; the differentiator is making it *visible and low-friction*: a guided Evidence-Explained citation builder, transcription/abstract fields, source-driven data entry (transcribe a document into the tree), per-fact confidence surfaced in the UI, and — critically — citations that **survive GEDCOM export**. These turn "every fact links to where it came from" from an architecture note into the product's personality.

+# Design note: tree visibility & the public viewing surface
+
+Status: **proposed** (design only — no code yet). Owner: Justin. Created 2026-06-09.
+
+This is a privacy-critical change (it creates the first anonymous read surface in
+Provenance). Per CLAUDE.md, design before code. Implementation should land in
+small, individually-reviewable PRs, with tests on the privacy engine and the
+public read path before any anonymous endpoint is exposed.
+
+## 1. The model
+
+Visibility flattens **two axes** — *who may read* and *how discoverable* — into one
+ordered enum for the UI:
+
+| Level | Anonymous (no login) | Any logged-in user | Tree members | In-app directory | Search-indexed |
+|---|---|---|---|---|---|
+| `public` — anyone on the web | ✅ view¹ | ✅ view¹ | ✅ full | ✅ listed to everyone | ✅ sitemap + indexable |
+| `site_members` — Public, Site Members | ❌ | ✅ view¹ | ✅ full | ✅ listed to logged-in users | ❌ (`noindex`) |
+| `unlisted` — anyone with the link | ✅ via direct link¹ | ✅ via link¹ | ✅ full | ❌ never listed | ❌ (`noindex`) |
+| `private` | ❌ | ❌ | ✅ full | ❌ | ❌ |
+
+¹ **Every non-member view passes through the privacy engine.** Living people are
+redacted, and per-person `private` hides / `public` reveals, exactly as
+`person_visibility()` already does (`backend/app/services/privacy.py:100-110`).
+This is the single enforcement point — no public code path may issue a raw query.
+
+Decisions captured (2026-06-09):
+- **Unlisted** = anyone with the link, no account required. The link must be
+  **unguessable** (the tree UUID is already non-enumerable; do not add a public
+  integer id). Unlisted trees are excluded from the directory and sitemap and
+  served `noindex`.
+- **Public** discovery for v1 includes **an in-app public browse/search**, not
+  just search-engine indexing.
+- **Public – Site Members** = *any* registered account on this instance (not an
+  invite list — that is already tree membership / `private`).
+
+## 2. Data model
+
+`TreeVisibility` enum (`backend/app/models/enums.py`) gains a value:
+
+```
+public        # anyone on the web
+site_members  # any authenticated user of this instance   <-- NEW
+unlisted      # anyone with the link
+private        # members only (default)
+```
+
+- Alembic migration to `ALTER TYPE tree_visibility ADD VALUE 'site_members'`
+  (Postgres enum add-value cannot run inside a transaction with other DDL — use
+  `op.execute` with autocommit, separate migration).
+- Default stays `private`. Existing rows unchanged.
+- `TreeRead`/`TreeUpdate`/`TreeCreate` schemas already carry the enum; they pick
+  up the new value automatically. The OpenAPI client regen (`gen:api`) exposes it
+  to the frontend.
+
+## 3. Privacy engine
+
+`can_view_tree()` today treats `public` and `unlisted` identically and ignores
+whether the viewer is anonymous vs authenticated (`privacy.py:44-49`). Replace the
+final line with explicit branching on viewer auth state:
+
+```
+if membership: return True              # members always
+match tree.visibility:
+  public, unlisted: return True         # anonymous OK (unlisted gated only by knowing the link)
+  site_members:     return user_id is not None   # any logged-in account
+  private:          return False
+```
+
+`person_visibility()` is unchanged — it already redacts living/private people for
+non-members. Add focused unit tests: anonymous + each visibility; living person
+redacted on public/unlisted; `site_members` denies anonymous but allows a
+logged-in non-member; `private` denies both.
+
+## 4. The anonymous read path (the careful part)
+
+**Recommendation: a dedicated read-only public API namespace**, not optional-auth
+on the existing endpoints. Rationale: it is far easier to audit a small,
+purpose-built surface that *always* funnels through `person_visibility` than to
+weaken the membership checks on the authenticated endpoints and hope every branch
+is covered.
+
+- New router `app/api/v1/public.py`, mounted at `/api/v1/public`, with an
+  **optional-auth** dependency `CurrentUserOrNone` (returns `User | None`; never
+  401s). Contrast with `CurrentUser` (`deps.py:30-36`) which hard-401s.
+- Endpoints (read-only; no create/update/delete):
+  - `GET /public/trees` — directory: lists `public` to everyone; additionally
+    lists `site_members` when the caller is authenticated. Paginated, search via
+    existing `pg_trgm`. Never lists `unlisted`/`private`.
+  - `GET /public/trees/{id}` — tree metadata if `can_view_tree(user_or_none)`.
+  - `GET /public/trees/{id}/persons`, `/persons/{pid}`, `/relationships`,
+    `/events`, `/media`, … — each filtered through `person_visibility`, returning
+    redacted projections (a `PublicPersonRead` that omits PII for redacted people:
+    no exact dates, no living-person names beyond "Living", etc.).
+- **A redacted response schema**, distinct from the member `PersonRead`, so the
+  serializer physically cannot emit fields a non-member shouldn't see. Redaction
+  happens in the service, not the route.
+- **Rate limiting** on the public namespace (per-IP) to blunt scraping/enumeration.
+- **Audit**: count public reads; do not log PII.
+
+## 5. Frontend public pages
+
+- New **server-rendered** routes outside the authed app shell, e.g.
+  `/p/[treeId]` (tree), `/p/[treeId]/[personId]` (person), `/explore` (directory).
+  Server components fetch the `/api/v1/public/*` endpoints; no login redirect.
+- `robots`: allow + sitemap for `public`; `noindex, nofollow` meta for `unlisted`
+  and `site_members`. Sitemap lists only `public` trees/persons.
+- The directory `/explore` is anonymous for `public`; shows `site_members` trees
+  only to logged-in users.
+- Reuse the tree/person view components where possible, fed by the redacted
+  schema.
+
+## 6. UI control
+
+Update the visibility dropdown (`frontend/app/trees/page.tsx`, shipped in PR #41)
+from 3 to 4 options with helper text:
+
+```
+Private          — only you and people you invite
+Public – Members — any signed-in user on this site
+Unlisted         — anyone with the link (not listed or indexed)
+Public           — anyone on the web; listed and search-indexable
+```
+
+A short confirmation when switching *to* `public` ("This makes <tree> visible to
+anyone on the web. Living people stay hidden.") is worthwhile given the stakes.
+
+## 7. Guardrails / invariants
+
+- One enforcement point: every public response is built from `person_visibility`
+  output. No raw repository reads in the public router.
+- Living-person protection holds regardless of tree visibility.
+- Unlisted relies on UUID unguessability; never expose a sequential public id.
+- `noindex` everything except `public`; sitemap is `public`-only.
+- Tests gate the merge: privacy-engine matrix + an integration test that hits the
+  public endpoints anonymously and asserts no living-person PII leaks.
+
+## 8. Suggested phasing (small PRs)
+
+1. Enum value + migration + regen client (+ dropdown → 4 options). No behavior
+   change yet for non-members.
+2. Privacy-engine branching + unit tests.
+3. Public read API namespace (optional-auth, redacted schema, rate limit) + tests.
+4. Public frontend pages (`/p/...`) + robots/sitemap.
+5. In-app `/explore` directory + search.
+
+Steps 2–3 are the privacy-critical core and should be reviewed hardest.
+
+## 9. Open questions
+
+- Caching: public pages are cacheable for SEO, but cache keys must not blur the
