Problem

Sending a prompt in a long thread waits seconds before the run shows as working. message.dispatch first loads every run, attempt, node, user message, provider turn and context transfer of the thread, although a thread that was compacted only needs what follows the compaction. On a thread with about 7,000 runs that read took 9-14 s in a server trace, and it is the whole wait: the run is created only after it.

Fix

  • Compaction window. The command read gains a sinceLastCompaction filter. It reads the runs from the one before the latest completed compaction, plus live runs, fresh-context runs and the runs the command names (continuation and delegated-completion runs). Run-scoped records (attempts, nodes, user messages, user-message and error items, provider turns) follow those runs. Provider threads are the thread's own, and context transfers are the open ones that target it. A thread with no completed compaction reads in full, as before.
  • Full history where it is handed on. A fresh-context start or a provider switch is given the whole history, so dispatchMessage re-reads in full for those.
  • Maintenance-only title check. "Only /compact or /logout so far" was computed from the loaded user messages. A window holding just a compaction would have matched it and regenerated the title, so it is now its own store query (hasOnlyMaintenanceUserMessages) that stops at the first other user message.
  • Settled-row filters. The settled-subagent and settled-leaf-node filters checked each run's status through the runs table. They now use the covering runs_id_status_idx from perf(server): long threads stop costing a full-history read per command #31757, and the settled-subagent read names subagents_settled_idx, so only open tasks read their payload.
  • Migration 083 adds two indexes: a partial index on fresh-context runs (a handful of rows) and provider_turns(run_attempt_id), which the window needs to find a run's turns. The partial index guards the payload with json_valid, like the other partial indexes on it, because legacy rows can hold unreadable JSON.

Query results for threads without a compaction are unchanged apart from the settled-row filters' access path.

Scope and approval

This changes how an existing read reaches its data and narrows what a new prompt loads from a compacted thread. It adds no feature and no product default. One problem: the wait before a prompt starts in a long thread, the read side of #29468.

Stacked on #31757. It needs that PR's migrations 081/082 and indexes, so the branch contains its commits until it merges. Review the last four non-merge commits (4dcd26f420, 2d7f3dffc1, 7836410431, 79ed278fd1) on their own; the diff shrinks to them after #31757 lands.

Evidence

Regression test. ProjectionStore.test.ts gains one case: after a compaction it reads the recent runs, a live older run, an older fresh-context run and a named older run, drops the other old runs and their messages, reads in full before any compaction exists, and inserts a run with an unreadable payload to check the fresh-context index accepts it (that insert fails without the json_valid guard). It fails on main because the filter does not exist. reconcileV2PreviewMigration.test.ts pins the manifest, so it gains the new entry.

Measured on a ZFS reflink copy of a real ~25 GB database (the live file was never opened for writing; one thread with 7,026 runs, 52,634 items, 4,254 context transfers and 388 provider threads; 80 compactions, the last one 46 runs before the newest; same machine, back to back). The thirteen record reads dispatchMessage makes, through the real store:

full read after a compaction
all command records 8.8-11.8 s 0.05 s warm, 0.17 s cold
runs / attempts 7,026 / 7,026 rows 47 / 47
nodes 10,949 69
user messages 7,359 49
provider turns / threads 7,010 / 388 47 / 3
context transfers 4,254 0
settled-subagent filter alone 1.45 s 15-24 ms

Run, attempt and node reads look runs up by key (an earlier draft filtered the thread's run index and took about a second), and the turn-item read uses the run index (an earlier draft fell into the type-only form and took 7-15 s). Both are fixed here.

What this does not show.

  • I have not timed a real send end to end on a running server. The numbers are the read the send waits on, not the whole dispatch transaction or the status publish after it.
  • The thread shell read (the chat-list status after the run is created) still counts every item of the thread: about 25-45 ms warm and up to 200 ms cold on this thread. Not changed here.
  • Other commands still read the full history: starting the next queued run, subagent finalize, delegate-task, and the wake and restart continuation reads. Each can hold up a send on the command queue. Not changed here.
  • Migration 083 builds its indexes on first start, before the server accepts connections. I have not timed the build on the full database.
  • A run older than the window that a command needs must be named by that command. dispatchMessage names its continuation, delegated-completion and explicit steer or restart target runs; I checked its other uses of runs, messages, provider threads and transfers by reading the code, not by test.

Verified with vp run check:changed (format, lint, knip, typecheck, tests for the changed files), plus the ProjectionStore, DelegatedCompletionDelivery, migration and manifest suites run in full.

Settling an app-owned subagent loaded every node, user message, subagent,
provider thread/turn and context transfer of the parent, to use one task, its
node, its item and its delivery cohort. On a dispatcher thread with 35k nodes
and 7k prompts that cost over a second of reads per child. It now reads the
records it names, and takes the result-transfer check from the child side.

MCP calls that identify their caller loaded the caller thread's provider
threads and turns, which no tool reads.

Without statistics SQLite answers a turn-item read filtered by run or node by
walking the thread's whole ordinal index (2.2 s on a thread with tens of
thousands of items), whether the filter is a run id, a run id list or node ids.
Name the matching index for each, and drop the always-false OR arm from the run
list so the run id can be a search key. A restart continuation does this read
once per interrupted run.

Finalizing a child at startup loaded every task and context transfer of its
parent to find its own; read the child's tasks through the child-thread index
and its result transfers from the child side.

…follows the compaction

A new prompt loaded every run, attempt, node, user message, provider turn and
context transfer of its thread before it could start a run, although a thread
that was compacted only needs what follows the compaction. On a thread with
about 7,000 runs that read took 9-14 s, and the run only showed as working after
it finished.

`message.dispatch` now reads the runs from the one before the latest completed
compaction, plus live runs, fresh-context runs and the runs the command names
(`sinceLastCompaction`). Run-scoped records follow those runs. Provider threads
are the thread's own, and context transfers are the open ones that target it. A
thread with no completed compaction reads in full, as does a fresh-context start
or a provider switch, which hand the whole history to the next provider.

The "only maintenance messages so far" title check no longer depends on the
loaded messages: a window holding only `/compact` would have regenerated the
title. It is its own query that stops at the first other user message.

Migration 083 adds the indexes the window reads need: fresh-context runs and
provider turns by attempt. The settled-subagent and settled-leaf-node filters
look up run status in the covering index, which takes the subagent read of a
3,900-task thread from 1.4 s to 15 ms.

🟠 High orchestration-v2/Orchestrator.ts:5626

An explicit steer or restart targeting a run older than the compaction window now fails as “not found” instead of starting a new turn: keepRunIds drops dispatchMode.targetRunId, so the completed-target fallback cannot see the run and dispatchSteerIntoRun rejects it. Include the target ID for steer_active and restart_active in keepRunIds.

Confirmed: an explicit steer_active or restart_active names its own target run, and a finished target older than the window was missing, so the command failed with "Target run ... was not found" instead of starting a new turn. Fixed in 7836410: the target is added to keepRunIds. SteeringCompletion.integration.test.ts gains a case with three finished turns and a compaction on the third, then a steer aimed at the first; it fails with that exact error without the change.

🟡 Medium orchestration-v2/Orchestrator.ts:5624

After consecutive /compact runs, the truncated projection drops the last ordinary prompt run, so the next prompt with a different model gets no modelSwitch even though the full history records a model change from that prompt. modelSwitchSince excludes compaction messages, leaving no baseline in the retained runs; preserve the last timeline-visible run as well as the compaction predecessor.

Confirmed: with a /compact run directly before the compaction, the window had no run whose prompt the timeline shows, so modelSwitchSince lost its baseline. Fixed in 7836410: the window now starts at the last prompt before the latest compaction that is not itself a /compact run (and not queued or rolled back). The compacted-thread case in ProjectionStore.test.ts now has a second compaction behind a /compact run and expects the window to start at the prompt before it.

Approvability

Verdict: Would Approve

Macroscope's review found this PR approvable — This change reduces history loaded for compacted threads and narrows subagent and provider-start queries, backed by additive database indexes. Stored history remains intact; the two supplied correctness findings remain subject to the separate blocking gate.

Needs human approval because:

  • 2 blocking correctness issues found at or above your repo's Minimum Blocking Severity

…eadable JSON

The partial index added for compacted-thread reads evaluated `json_extract` on
every run row, so writing a run whose stored payload is not valid JSON failed
with "malformed JSON". Guard it with `json_valid`, as the other partial indexes
on the run payload do, and insert such a row in the compacted-thread test.

Walkthrough

The projection store now supports reads limited to runs since the latest completed compaction, retained runs, and targeted records. Orchestration uses these reads for message dispatch, provider-run checks, title-generation eligibility, and delegated-task completion. Three migrations add supporting query indexes.

Changes: Projection reads and orchestration

Layer / File(s) Summary
Compaction-aware projection reads
apps/server/src/orchestration-v2/ProjectionStore.ts, apps/server/src/orchestration-v2/ProjectionStore.test.ts
The store adds compaction-window and child-thread filters, targeted getRun and maintenance-message queries, and filtered query paths. Tests cover compaction-window selection and indexed reads on long histories.
Projection query indexes
apps/server/src/persistence/Migrations.ts, apps/server/src/persistence/Migrations/081_ProjectionRunsExecutedIndex.ts, apps/server/src/persistence/Migrations/082_CommandReadIndexes.ts, apps/server/src/persistence/Migrations/083_CommandWindowIndexes.ts, apps/server/src/persistence/reconcileV2PreviewMigration.test.ts
Migrations 81–83 add indexes for projection run, turn-item, fresh-context, and provider-turn queries. Migration tests include the new entries.
Command dispatch and provider reads
apps/server/src/orchestration-v2/Orchestrator.ts, apps/server/src/orchestration-v2/ProviderTurnStartService.ts, apps/server/src/orchestration-v2/ProviderTurnStartService.test.ts, apps/server/src/orchestration-v2/ProviderTurnControlService.test.ts, apps/server/src/orchestration-v2/SteeringCompletion.integration.test.ts
Message dispatch uses a compacted projection with retained runs and reloads full history under specified conditions. Provider-run checks use targeted reads, and title-generation eligibility uses the maintenance-message query. An integration test covers steering after compaction.
Delegated-task completion reads
apps/server/src/orchestration-v2/Orchestrator.ts, apps/server/src/orchestration-v2/DelegatedCompletionDelivery.test.ts
Delegated-task finalization uses targeted task and delivery records and checks result transfers in the child thread. A recovery test verifies parent-node reads use a node ID filter.

… the last shown prompt

Two runs the compaction window dropped were still needed by a new prompt:

- An explicit steer or restart names its target run. When that run finished
  before the window, the target was missing, so the "target already finished,
  start a new turn" path could not run and the command failed with "Target run
  was not found". The target is now kept like the other named runs.
- A model switch is measured from the last run whose prompt the timeline shows,
  and `/compact` prompts are not shown. When the run before the compaction was
  itself a `/compact` run, the window held no baseline and the switch was lost.
  The window now starts at the last prompt before the compaction that is not a
  `/compact` run.

…nreadable JSON

The search for the last prompt before the latest compaction read each earlier
run's payload with `json_extract`, so walking past a legacy run whose stored
payload is not valid JSON failed the whole read and blocked the next message.
Guard it with `json_valid`, so such a run is never a window start. A run older
than the window is not read at all, and the compacted-thread test now has a
thread whose only earlier run is unreadable.

Takeover update

merged current main (08af12da49) into the branch with a merge commit (e5473e911c). no other source changes.

  • ProjectionStore.ts: kept both sides. main's threadColumn (+thread_id for id filters) now applies to the compaction-window reads too, except where this pr forces a thread-prefixed index (nodes_thread_run_idx, the subagent child_thread/settled indexes), since +thread_id would stop INDEXED BY from using it.
  • OrchestratorMcpService.ts: took main's side. perf(server): MCP tool calls no longer read the caller's whole thread #33295 removed loadProjection/loadProjectThread, so this pr's trim of their provider fields is no longer needed.
  • the three bot findings (steer target outside the window, /compact baseline for model switches, unreadable legacy JSON in the predecessor search) were already fixed in 7836410431 and 79ed278fd1.
  • blacksmith vp run check:changed: format, lint, knip, graphql and typecheck passed; 227 of 228 tests passed. the one failure is main's reads a fixed SQL turn-item window test, which calls statement.stat and needs node 26; the worker ran node 24. CI runs it on node 26.

the verification below was done on the previous head 79ed278fd1 by an earlier run.


Verified in a real dev environment

verified head 79ed278fd131f12b1a42ca90db1df412b8bfe60c on linux with the real dev web client, repo playwright, /usr/bin/google-chrome, and codex gpt-6.1-sol. no source changes were needed.

  • ran github/main at bcee0f5d2872ba193c66ed9ba979bbe424f89ff9 first in a separate worktree. created a real git project through the app, sent two provider turns, ran /compact, then asked for an earlier marker. the server trace still showed unbounded thread-wide run and attempt reads.
  • stopped main before running the exact pr head. used the same app-created pre-recall database baseline in isolated state. the same send succeeded and returned cobalt-maple-33000. its trace contained ProjectionStore.runsSinceLastCompaction, bounded run/attempt reads, the provider-turn attempt index, and only open incoming context transfers. the title stayed Save Verification Marker.
  • /clear followed by a message performed the full-history fallback read, created a different native codex thread, and returned FRESH SESSION OK. a subsequent real terminal call ran cat README.md and returned its heading. browser reload retained the conversation and results.
  • blacksmith: 176 focused tests passed. vp run check:changed ade473018d32003658b7d38693e083ee2e314bd8 passed format, lint, both knip passes, graphql, affected-package typechecks, and 271 tests in 13 files. the explicit merge base was needed because the worker has shallow history.

main, after compaction and recall:

main returns the saved marker after compaction

pr, the actual post-compaction send and response:

post-compaction send returns the saved marker through real codex

pr, fresh session and terminal call:

Not verified

the app-created history was small. this reproduced the full-history read path on main, but not the reported 9-14 second delay on a 7,000-run thread. no large-history speedup or large-database migration timing is claimed.

native desktop and ios/android clients, other providers, cross-provider switching, live subagent completion, and explicit steering to an older finished run were not exercised end to end. existing regression tests covered the older-run steering case and delegated completion.
