feat: add prompt history plugin Host prerequisites - #3588
Conversation
- Journal primary conversation mutations into an immutable, transactional outbox (SQLite triggers and PostgreSQL functions) with backfill and retention. - Mirror committed rows into a durable session event log that survives restarts and preserves terminal tombstones. - Stream ordered session events over websocket with consumer cursors, resume tokens, ACK identity checks, poison detection, audit, and operator requeue. - Publish a browser plugin conversation facade (snapshots, continuation renewal, ordered projection, poison rebind) with mobile parity. - Sanitize private system content at every journal persistence boundary and keep snapshot/live payload projections consistent. - Centralize session deletion so the durable removal outbox row commits with the delete before events are published. - Harden plugin loading and registry atomicity: serialized registration, translation and work-lifecycle rollback, deep registry copies.
- Mirror resync heals forward gaps left by retention collection on both sides, so a pruned primary (only the session.removed row remains) can re-sync a collected terminal partition instead of failing forever. - Sanitize system content identically across dialects: SQLite triggers now remove every multi-line, multi-block block through a bounded recursive strip that mirrors the Go helper; PostgreSQL drops the newline-sensitive flag. Retroactive migrations rewrite both stores. - Prune dead-session journal partitions wholesale (versions, events, and stream rows) once the source session is gone and retention elapses. - Journal turn deletion in both dialects by removing the turn's version history without consuming a stream sequence or emitting an event row. - Count poison attempts only on observed delivery, never on maintenance ticks; poisoned frames are dropped from the committed fanout like the local append path. - Fallback message pages honor task_id and multi-author filters for parity with the journal branch. - Pin messages-capability minimum enforcement on dev and unwired builds.
- SQLite system-content strip keeps the raw text when no well-formed block exists (unterminated opener or stray closer) instead of returning NULL, matching the Go helper; tag arithmetic uses length() and the deepest recursion row is emitted, so journal payloads and migrations never store content null for such inputs. - Unify poison delivery: poisoned frames are delivered to live subscribers on both the append and mirror fanouts (clients recover on seeing them), and a delivery attempt is counted only when a recipient exists. - Guard journal trigger creation, the one-time sanitize migration, and the corpus backfill behind a schema-version/backfill meta marker so boot no longer rewrites the whole journal or rescans the source corpus; the PostgreSQL migration narrows its rewrite to marker rows. - Mirror sync isolates one unhealthy partition so retention passes keep running, and heal jumps emit a structured audit log. - Journal pagination errors instead of silently truncating when the page cursor message was deleted mid-walk. - Document bounded removal retention and the accepted deleted-turn replay divergence; add a Postgres-DSN-guarded journal round-trip test.
- PostgreSQL message triggers now insert conversation_session_events rows in the same transaction as the version row, so PG mirrors reach live/replay delivery like SQLite; the AFTER trigger returns NULL. - Mirror sync scans the session_id column, so mirrored events, partitions, and poison records are keyed to the real session instead of an empty id. - Malformed primary-journal rows mirror with a non-nil empty payload and survive as durable poison records on the file-backed log. - The browser scope seeds acknowledgedSequence/nextSequence from the subscribe watermark (watermark+1) so non-empty sessions drain live frames. - session.removed is accepted for the selected session regardless of task_id; other events still require exact task identity. - commitSnapshot preserves unprocessed tails, stops at terminal removal, and drives poison/rebind instead of dropping events on projection failure. - session.event-shaped frames that fail the strict envelope check trigger core poison recovery instead of stalling silently. - Backfill selects and inserts in one transaction with optimistic source re-checks; sender_task_id is typed (string-only) across triggers, backfill, and PostgreSQL. - Poison attempt leases use the delivery time, not the event creation time. - Retained replay gaps return the replacement-cursor result instead of a mislabeled contiguous replay. - Ordered fanout re-authorizes subscribers at delivery time and revokes denied ordered subscriptions. - Regression tests cover each fix: PG message event rows, durable malformed mirror, cursor watermark seeding, removal task mismatch, post-terminal non-resurrection, malformed-envelope recovery, sender typing, retained-gap rebind, and authorization-gated recipients.
- Session ACKs persist only the advanced cursor row (single upsert) instead of rewriting every retained partition, event, cursor, poison record, and audit, removing the O(all-history) write amplification and lock on the hot contiguous-event path; regression proves other cursors, partitions, and events survive a delta write across restart. - Fresh full message pages (initial load, retry, and binding refresh) now invalidate the committed messages snapshot before fetching, so a live event that lands mid-fetch buffers and is drained on top of the new page instead of being projected and then overwritten by the stale page response; regression covers loadMore failure, retry, and a concurrent update.

Merge Risk: 🟠 High · up to This change introduces the Host-side plugin conversation boundary with durable event streaming. Several defects in that new machinery can silently drop conversation events, crash the backend during routine stream maintenance, hang a browser tab that requests a mismatched task, and skip cleanup after a session is deleted; one new backend test file also fails to compile, and the first startup after upgrade can hold a long write transaction proportional to total message history. These should be resolved before merge. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Inline comments:
In `@apps/backend/internal/backendapp/helpers.go`:
- Line 1487: Update the route registration call using p.services.Task so a nil
task service does not become a typed-nil ConversationReader argument; omit the
fifth argument when p.services.Task is nil, while preserving the existing
argument order and behavior when it is non-nil.
In `@apps/backend/internal/gateway/websocket/client.go`:
- Line 436: Update the SyncCommittedSessionEvents handling in the subscribe flow
to capture its returned events and broadcast each one through
broadcastCommittedOrderedSessionEvent before resolving replay. Preserve the
existing error handling and ensure newly appended mirrored rows reach current
subscribers before replay completion.
In `@apps/backend/internal/office/testharness/routes.go`:
- Around line 908-912: Update the turn event data construction around turn.ID to
format StartedAt and UpdatedAt as RFC3339Nano strings and safely handle a nil
CompletedAt, emitting the required non-empty completed timestamp string expected
by validateSessionEventPayload. Match the timestamp formatting used by
publishSessionStateChanged, publishMessageAdded, and messageEventData.
In `@apps/backend/internal/orchestrator/task_operations.go`:
- Around line 3428-3433: Update deleteSessionAndPublishRemoval in
apps/backend/internal/orchestrator/task_operations.go:3428-3433 to log any
eventBus.Publish failure and return nil after a successful deletion, preserving
return of the actual delete error. In
apps/backend/internal/orchestrator/event_handlers_workflow.go:2507, make no
direct change; the helper fix prevents this branch from treating notification
failure as deletion failure or updating an already deleted session.
In `@apps/backend/internal/plugins/conversation_handlers_test.go`:
- Line 401: Replace the invalid new("task-1") usages in the affected test setup
with an existing string-pointer helper, or define a local helper returning
*string, and pass its result to both token helpers so the test file compiles.
In `@apps/backend/internal/plugins/conversation_handlers.go`:
- Around line 356-363: Align the task scope used by both branches in the
conversation-turn loading logic around conversationTurnsAt and
loadFallbackTurns. When taskID is absent, ensure both paths consistently use the
same scope—either the inherited session.TaskID or no task filter—and preserve
the corresponding behavior for explicitly requested tasks.
- Around line 62-68: Update the loadFallbackTurns call site to pass
ctx.Request.Context() instead of the *gin.Context, preserving request
cancellation through reader.ListTurnsBySession and matching the other handlers
in the file.
- Line 236: Update both conversation GET/read handlers to set the response
header Cache-Control to no-store before returning their JSON responses,
including the handler containing ctx.JSON(http.StatusOK, response). Preserve the
existing response payload and status behavior.
In `@apps/backend/internal/plugins/conversation_stream_test.go`:
- Around line 135-139: Set ProtocolVersion to SessionEventProtocolVersion on all
four SessionEvent literals passed to AppendCommitted in the affected tests,
matching the existing correctly configured literal. Keep the tests exercising
healthy mirrored events so truncation and forward-gap healing assertions
validate the intended paths.
In `@apps/backend/internal/plugins/conversation_stream.go`:
- Around line 1118-1130: Check rows.Err() after the rows.Next() loops in both
loadPartitions and loadEvents, returning a wrapped error when iteration fails
before normal exhaustion. Match the existing loadJSONRows error-handling pattern
while preserving the current scan, close, and successful-load behavior.
- Around line 129-139: Update Append to validate json.RawMessage payloads before
storing them and return an error for invalid JSON, preventing malformed records
from entering partition.Events. Change cloneSessionEventLogState and its callers
to propagate cloning/serialization errors instead of panicking, while preserving
existing state-copy behavior for valid payloads.
- Around line 340-341: Update AppendCommitted to capture previousWatermark
before the gap-heal branch mutates partition.Watermark, then restore
partition.Watermark to that saved value when persistAppendLocked fails instead
of decrementing it by one. Preserve the existing event rollback behavior.
In `@apps/backend/internal/plugins/registry.go`:
- Around line 155-161: Update cloneRecord to use an explicit manifest clone
rather than the JSON marshal/unmarshal fallback, ensuring clone.Manifest never
aliases the stored record. Add manifest.Manifest.Clone() that deep-copies every
nested slice and map, then use it when constructing the cloned record.
In `@apps/backend/internal/plugins/service.go`:
- Line 723: Update maintainSessionEvents to accept a context.Context parameter
and use it for both syncAllCommittedSessionEvents and pruneConversationJournal
instead of context.Background(). Pass workerContext from the
StartSessionEventMaintenanceWorker ticker loop, and update callers in the
affected tests to provide the new argument.
In `@apps/backend/internal/task/repository/sqlite/conversation_journal.go`:
- Around line 203-214: Update backfillConversationJournal to process unjournaled
turns and messages in bounded batches using session pagination or a keyset
cursor over (task_session_id, created_at, id), committing each batch
independently. Preserve the existing NOT EXISTS filtering and insertion behavior
so retries remain resumable and idempotent, while avoiding loading full Content
and Metadata history or holding one transaction for the entire corpus.
- Around line 441-442: Add an opening-tag presence guard to the recursive WHERE
clause and depth-bound CASE in the SQLite journal stripping logic near the
existing recursive expression. Extend the test cases in
apps/backend/internal/task/repository/sqlite/conversation_journal_test.go lines
214-218 with a closing-tag-without-opening-tag input, ensuring the parity
assertion at lines 238 preserves the visible text.
In `@apps/web/components/task/mobile/session-mobile-layout.tsx`:
- Around line 669-670: Update the mobile scroll-target handler guard to also
return unavailable when isPassthroughMode is true, and include isPassthroughMode
in the callback dependency list so the handler reflects mode changes.
In `@apps/web/components/task/plugin-task-panel.tsx`:
- Line 94: Update the conversation.openMessage lease identity in the task panel
callback to include the plugin generation and the effective visibility result
from registrationIsVisible(...), so retained callbacks are revoked after reloads
or visible-to-hidden transitions. Add regression tests covering both generation
changes and visibility changes.
In `@apps/web/lib/plugins/conversation-event-projection.ts`:
- Around line 21-23: Update compareConversationMessages to compare parsed
timestamp instants rather than using localeCompare on createdAt, preserving
sub-millisecond precision when needed; use a locale-independent comparison for
message IDs only when timestamps are equal, and retain a deterministic fallback
ordering for invalid timestamps.
In `@apps/web/lib/plugins/conversation-host.tsx`:
- Line 509: Memoize the task resolution in both useSessionMessages and
useSessionTurns so resolved.error retains stable identity for identical scope
and query.taskId inputs. Update the resolved value around resolveTaskId and
preserve the existing valid-task and invalid-task behavior, preventing dependent
callbacks and effects from rerunning indefinitely.
- Around line 292-299: Update both conversation read request option objects in
conversation-host.tsx, including the requests near lines 292-299 and 693-700, to
set cache to "no-store". Apply the change to both the message and turns fetches
while preserving their existing credentials, headers, and abort signal options.
In `@apps/web/lib/plugins/host.ts`:
- Line 259: Move the setPluginDeclarations(plugin) call out of the
pre-initialize path and into publishPluginGeneration, committing declarations
together with the staged registrations only after initialization succeeds.
Preserve the existing previous runtime and metadata until publication completes,
including on timeout or failure.
- Line 395: Update the cache reuse logic around the cached plugin lookup so a
replacement runtime never reuses the exact KandevPlugin instance owned by
previousRuntime when generations overlap. Ensure each replacement generation
receives a distinct plugin object, while preserving reuse only where it cannot
share an active runtime’s object and keeping retireRuntime from destroying the
newly published generation.
- Around line 183-185: Update the registration flow around registrationStages
and registerKandevPlugin so each bundle import is bound to its own unforgeable
registration token, preventing a callback from claiming another plugin’s open
stage. Preserve valid same-import registration and ensure concurrent plugin
loads cannot cross-register; add a concurrency test verifying plugin B
initializes only its own implementation.
- Around line 403-404: Update resolveRegistration to recheck registeredPlugins
after awaiting previousRegistration and return the cached registration before
importing or creating a new stage. Add a test covering two overlapping loads
with the same plugin ID and bundle URL, verifying both complete successfully and
receive the registered plugin.
In `@apps/web/lib/plugins/registry.ts`:
- Line 187: Update the mutation rollback logic around deferredWorkAborts to
snapshot the set for each mutation level and restore the appropriate snapshot
when a nested mutation fails, rather than clearing the shared set globally.
Preserve aborts queued by outer mutations so providers for plugins that remain
unregistered are still aborted when the outer mutation commits.
In `@apps/web/lib/ws/client.ts`:
- Line 775: Update the fire-and-forget acknowledgeCoreSessionEvent calls in the
relevant session-event handling paths to catch rejected session.ack promises. On
rejection, perform the existing safe retry or ordered-cursor rebind recovery
before allowing the stream to advance, while preserving normal acknowledgment
behavior.
- Around line 733-740: Update all ordered subscription response handling paths,
including the ACK path and the locations corresponding to the other ordered
responses, to validate the success discriminator, session and consumer
identities, sequence, watermark, result, and required resume token before
mutating readiness or stream cursor state. Reject both unsuccessful and
incomplete/mismatched payloads, ensuring fields such as stream.lastSeenSequence
and stream.resumeToken are updated only after complete validation succeeds.
In `@apps/web/lib/ws/ordered-session-events.ts`:
- Line 47: Update the ordered event classification around orderedCoreAction so
each project-mapped payload is validated for the required fields of its event
type, including message and session IDs where applicable. Return "poison" for
malformed payloads instead of "project", while preserving project classification
for valid payloads.

requests without these filters and pass the effective limit alongside
AuthorTypes and TaskID.
In `@apps/web/e2e/tests/plugins/mobile-prompt-history-plugin.spec.ts`:

visibility-gated assertions in this test. Keep the minimum height check
unchanged after visibility is confirmed.
In `@apps/web/e2e/tests/plugins/prompt-history-plugin.spec.ts`:
- Around line 97-99: After the second alias.click() in the prompt-history test,
assert that the prompt preview is no longer visible or mounted before clicking
the “Open prompt” button. Keep the existing interaction order and use the
preview’s established locator or identifying symbol.
- Line 71: Make the paging step in the prompt-history test deterministic by
removing the isVisible conditional around the loadOlder locator and waiting for
the control before clicking it, matching the mobile spec’s behavior. Use strict
locator resolution so missing or changed controls fail the test rather than
silently skipping pagination.
In `@apps/web/lib/plugins/conversation-host.test.tsx`:

Tip
PR walkthrough: Open the visual walkthrough
Prompt History is currently part of the core application, but the goal is to move it into an optional plugin. This PR delivers Step 1: the capability-gated Host contract and durable conversation transport needed to build that plugin safely, while preserving the existing core panel until Step 2 proves parity.
Important Changes
host.conversationboundary with sanitized message and turn DTOs.Validation
make installpnpm run typecheckpassed forapps/web.internal/task/serviceremain environment-sensitive in this runner.This page couldn’t load; no product assertion was reached.No screenshots are included because Step 1 changes Host contracts, transport, and a test-only fixture; it does not alter the shipped core Prompt History UI. The production Prompt History plugin is Step 2.
Possible Improvements
The follow-up Step 2 plugin still needs to prove desktop/mobile parity, migrate saved panel identifiers, and remove the core panel only after parity validation.
