fix(sharing): keep thread read markers personal - #909
Opening or marking a shared thread unread changes everyone's view. This implements personal read markers from #629; snooze and pin remain shared, so the issue stays open.
What changed
Read markers are keyed by authenticated person and thread, shared across that person's devices. Viewers can change their own markers within their thread access. Never-opened threads show fresh completions as unread, while imported history retains its null-marker behavior. Clients retain known markers through disconnects and reconnects, clear them on a person change, and use legacy commands on older servers.
Shared search-open ranking requires the authenticated device's operate permission. An admitted personal open updates ranking under the orchestrator's dispatch lock without moving the shared watermark, including when it is null. Receipt admission precedes ranking writes.
Personal commands carry an id of at most 128 characters and an immutable issuance time. Receipts expire after 24 hours and are capped at 65,536 per person; expired retries are refused, never silently replayed after pruning. Explicit retries must supply the original id and issuance time. This updates the still-unmerged personal-read RPC; released servers without the capability keep their existing route.
Migration 058 inherits legacy markers only for the first owner, including first adoption of an upstream database whose owner has not yet been created. Agents no longer see mark-unread in the adapted tool's action schema. Merged current j5/main and reconciled the migration and documentation IDs.
Validation
At 35725e47b, vp run check:changed passed: 283 tests across 25 files, typechecks for all 40 affected packages, formatting, lint, both Knip passes, GraphQL, unused patches, and React Compiler checks (10 checks). A final documentation-only file-table addition passed formatting separately. CI's full suites/build remain separate.
Regressions were observed failing before the fixes for unread projection, disconnected initial state, read-only ranking writes, and null shared watermark mutation. Added coverage exercises late-owner migration, oversized/invalid commands, receipt saturation, expired mark-unread replay after a newer visit, rejected-open ranking, generated command IDs, preserved retry issuance, and person changes. One independent patch review identified additional retry, admission, and reconnect cases, which were addressed and retested.
Live testing
On 2026-11-11 the primary agent used J5's browser panel and a disposable setup-agent-live-test.ts worktree, with separate Owner and project Viewer sessions. Two free Replay (dev) todo-list turns completed through the UI. A Viewer who had never opened the new thread saw Done/unread while the Owner viewing it stayed read. Opening it as the Viewer cleared their indicator. During a stopped server and after restart, a previously read thread stayed read and a never-opened completed thread stayed unread.
The final browser run used d07f8ba8a; its source tree matches 35725e47b except one FORK.md file-table row. No later runtime changes were made. Migration upgrade/late-owner behavior, permission narrowing, quota/expiry and retry ordering were validated with automated tests. This follow-up did not repeat native mobile/Electron, physical-device/relay/tunnel, fresh wizard, copied-real-data migration, or paid model behavior/evals.
Before

A never-opened Viewer thread stays unread while a visited thread stays read during reconnect
Earlier author verification at e4fc96562d covered baseline-to-head upgrade, two Owner sessions, personal mark-unread in both directions, and approved Haiku completions. The images below are that earlier evidence, not a claim that those exact scenarios were rerun on the final commit.
Earlier before/after UI evidence
The Done/unread indicator now follows the signed-in person. In the first pair below, the Owner marks the completed thread unread: the baseline changes the Viewer too, while the head leaves the Viewer read.

After
Viewer after Owner marks the completed thread unread
A second session for the Owner receives their unread marker
Bastian requested personal unread state on 2026-11-02. The decision is register D46; maintained composition points and file mappings are in FORK.md case 117. Personal state is J5-owned. Upstream hooks cover capability/RPC registration, shared client state and visit tracking, app composition, and thread.visit.preserveReadMarker under the dispatch lock. Migration 058 follows main's existing 052–057 migrations.
Shared web/desktop/mobile implementation; native/remote live limits stated
Product documentation updated
Models: GPT-6 Astra and GPT-6.1 Sol for the original implementation; GPT-6 Astra for these fixes and independent patch review. Harness: Codex in J5 Code. Earlier crew review included Opus and Fable with Claude Security.
This change adds per-person thread read markers with server persistence, RPC commands, and subscriptions. Client thread state uses personal markers when supported and retains legacy operations otherwise. The change also updates access rules, migration behavior, sharing controls, tests, and documentation.
Contracts define the marker and command schemas, WebSocket methods, permissions, and the j5PersonalThreadReads capability. thread.visit can also preserve the shared read marker.

Migration 58 creates personal marker and command-receipt tables and conditionally imports legacy markers. ThreadReadState validates commands, persists markers and receipts, and streams snapshots and changes. Thread visits can update ranking while preserving the shared marker.

The server wires thread-read handlers into WebSocket RPC and applies read-scope and thread-access rules. Guest configuration preserves the capability. The organize tool excludes mark_unread.
The client runtime subscribes to personal markers and selects personal or legacy commands by capability. Web and mobile thread state passes markers to detail and shell projections. The web migration skips threads when personal reads are enabled.
Web controls and behavior documentation apps/web/src/j5/sharing/access.ts, apps/web/src/j5/sharing/sharingMenu.ts, apps/web/src/j5/sharing/sharingMenu.test.ts, docs/j5/product/features/shared-conversations.md, docs/j5/product/features/people-and-access.md, docs/j5/upstream.md, FORK.md, apps/server/src/provider/agentContextBudget.json
The sharing menu retains Mark unread for Viewers when personal reads are supported. Product and integration documentation describe per-person markers and related behavior.
Read markers now live per person, with only narrow edge cases left: a device with a clock ahead of the server can leave later completions looking read, unclaimed devices may not keep read state, and a local visit may not carry over on older servers. These are bounded and recoverable. Address them before or soon after merge.

Clamp the personal visit timestamp to server time.
ThreadReadState.change stores the client's visitedAt as sent. A device clock ahead of the server writes a future marker. The MAX upsert keeps that value through later visits, so completions before it show as read until the thread is marked unread.

Bound the j5_thread_read_command receipts. Nothing prunes them.
Each new visit or mark-unread command inserts a row into j5_thread_read_command (ThreadReadState.ts:171-172). The row is written even when last_visited_at does not change. No delete, prune, or retention path covers this table. Add a retention rule that keeps receipts for the retry window, or document that growth is intended.

Add a revoked markUnread assertion to the permission test.

The test seeds one thread, so it cannot detect a lookup that applies one person's marker to every thread in the environment. The production lookup at threadShell.ts:176 is keyed by thread.id, so the current code is correct. Adding a second thread that Alice has no marker for makes that regression visible. Alice's lastVisitedAt on that thread should stay null.

Remove mark_unread from the t3_thread_organize description.
The description at threadTools.ts:64 still says the tool can "mark a thread unread". The handler at lines 306-311 refuses mark_unread on every call, so an agent that follows the description makes a call that always fails. The action enum still lists mark_unread, because parametersSchema comes from upstream. A complete fix also needs that enum changed.
Suggested description fix
- "Pin, snooze, settle, archive, or mark a thread unread. Omit `threadId` for this thread. `snooze` needs `snoozedUntil`. Settling this thread applies at turn end. A failed turn or queued message leaves it active. Archive hides the agent and closes its Exchanges; unarchive restores it without reopening them.

Archive does not interrupt a running turn.",+ "Pin, snooze, settle, or archive a thread. Omit `threadId` for this thread. `snooze` needs `snoozedUntil`. Settling this thread applies at turn end.

Seed the first owner's read markers when the owner row is created after migration 052.
Migration 052 copies legacy visits only for an existing is_local_operator = 1 row. On a database that has visits but no owner row, the owner is created at the next server start, after the migration has run. The migration does not run again, so that owner's previously read threads appear unread.

Stop advertising personal reads to sessions without a person.
Narrowed sessions without a person binding, such as unclaimed devices, now receive j5PersonalThreadReads: true. The web client then sends visits and mark-unread to the personal RPCs. Those RPCs refuse with not-person. The web client reports no failure and keeps no local read state. Before this change, these sessions kept local read state. Send the flag only when the session reach is person, or fall back to local state on not-person.

Problem
Opening or marking a shared thread unread changes everyone's view. This implements personal read markers from #629; snooze and pin remain shared, so the issue stays open.
What changed
Read markers are keyed by authenticated person and thread, shared across that person's devices. Viewers can change their own markers within their thread access. Never-opened threads show fresh completions as unread, while imported history retains its null-marker behavior. Clients retain known markers through disconnects and reconnects, clear them on a person change, and use legacy commands on older servers.
Shared search-open ranking requires the authenticated device's operate permission. An admitted personal open updates ranking under the orchestrator's dispatch lock without moving the shared watermark, including when it is null. Receipt admission precedes ranking writes.
Personal commands carry an id of at most 128 characters and an immutable issuance time. Receipts expire after 24 hours and are capped at 65,536 per person; expired retries are refused, never silently replayed after pruning. Explicit retries must supply the original id and issuance time. This updates the still-unmerged personal-read RPC; released servers without the capability keep their existing route.
Migration 058 inherits legacy markers only for the first owner, including first adoption of an upstream database whose owner has not yet been created. Agents no longer see mark-unread in the adapted tool's action schema. Merged current
j5/mainand reconciled the migration and documentation IDs.Validation
At
35725e47b,vp run check:changedpassed: 283 tests across 25 files, typechecks for all 40 affected packages, formatting, lint, both Knip passes, GraphQL, unused patches, and React Compiler checks (10 checks). A final documentation-only file-table addition passed formatting separately. CI's full suites/build remain separate.Regressions were observed failing before the fixes for unread projection, disconnected initial state, read-only ranking writes, and null shared watermark mutation. Added coverage exercises late-owner migration, oversized/invalid commands, receipt saturation, expired mark-unread replay after a newer visit, rejected-open ranking, generated command IDs, preserved retry issuance, and person changes. One independent patch review identified additional retry, admission, and reconnect cases, which were addressed and retested.
Live testing
On 2026-11-11 the primary agent used J5's browser panel and a disposable
setup-agent-live-test.tsworktree, with separate Owner and project Viewer sessions. Two freeReplay (dev)todo-list turns completed through the UI. A Viewer who had never opened the new thread saw Done/unread while the Owner viewing it stayed read. Opening it as the Viewer cleared their indicator. During a stopped server and after restart, a previously read thread stayed read and a never-opened completed thread stayed unread.The final browser run used
d07f8ba8a; its source tree matches35725e47bexcept one FORK.md file-table row. No later runtime changes were made. Migration upgrade/late-owner behavior, permission narrowing, quota/expiry and retry ordering were validated with automated tests. This follow-up did not repeat native mobile/Electron, physical-device/relay/tunnel, fresh wizard, copied-real-data migration, or paid model behavior/evals.Viewer opens the never-opened completion and clears its indicator (MP4 download). Signed-out download returns HTTP 200; GitHub serves it as
application/octet-stream, so inline playback is not claimed.Earlier author verification at
e4fc96562dcovered baseline-to-head upgrade, two Owner sessions, personal mark-unread in both directions, and approved Haiku completions. The images below are that earlier evidence, not a claim that those exact scenarios were rerun on the final commit.Earlier before/after UI evidence
The Done/unread indicator now follows the signed-in person. In the first pair below, the Owner marks the completed thread unread: the baseline changes the Viewer too, while the head leaves the Viewer read.
Second Owner session receives the unread update (MP4 download). GitHub serves this file as
application/octet-stream; an inline GitHub player has not been verified.The approved Haiku run exercised a new completion as well:
Real Haiku completion changes only the away person's unread state (MP4 download).
Upstream impact
Bastian requested personal unread state on 2026-11-02. The decision is register D46; maintained composition points and file mappings are in FORK.md case 117. Personal state is J5-owned. Upstream hooks cover capability/RPC registration, shared client state and visit tracking, app composition, and
thread.visit.preserveReadMarkerunder the dispatch lock. Migration 058 follows main's existing 052–057 migrations.Checklist
Models: GPT-6 Astra and GPT-6.1 Sol for the original implementation; GPT-6 Astra for these fixes and independent patch review. Harness: Codex in J5 Code. Earlier crew review included Opus and Fable with Claude Security.
