## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies, so
planning approvals and child-issue fan-out are part of the core
control-plane loop.
> - Accepted plans are supposed to be a safe bridge from planning into
execution, especially when agents wake from review decisions and reuse
isolated workspaces.
> - The duplicate-subtask incident showed that an accepted plan revision
could be interpreted more than once across overlapping runs, which broke
the single-source-of-truth model for issue decomposition.
> - Fixing that required tightening the backend contract first:
accepted-plan decomposition needs an exact-once fingerprint, durable
claim state, and retry-safe child creation.
> - Once that backend behavior existed, the board still needed
visibility into what happened, so the issue detail view needed a
dedicated decomposition section instead of forcing operators to
reconstruct child creation from raw activity.
> - This pull request adds the exact-once decomposition primitive,
hardens wake routing and regressions around the incident, and surfaces
decomposition state in the UI so future incidents are both prevented and
easier to inspect.
## What Changed
- Added accepted-plan decomposition semantics to
`doc/execution-semantics.md`, including the exact-once fingerprint,
durable claim/result expectations, and retry/resume behavior.
- Added persistent accepted-plan decomposition claims in the backend,
including schema, shared types/validators, service logic, and issue
routes for creating and listing decomposition state.
- Hardened heartbeat routing so an accepted-plan continuation stays
scoped to the relevant planning issue instead of opportunistically
re-decomposing another accepted issue on the same assignee.
- Added regression coverage for the original failure modes: concurrent
same-parent retries, cross-issue accepted-plan isolation, and partial
child recreation under the same fingerprint.
- Added the `Plan decomposition` issue-detail section plus supporting
API/query-key/activity formatting updates so operators can see revision
status, owner, child counts, and the linked child issues directly in the
UI.
- Included the small follow-up UI fix so the decomposition section still
renders when the issue work mode is no longer `planning`.
## Verification
- `pnpm --filter @paperclipai/server typecheck`
- `pnpm --filter @paperclipai/ui typecheck`
- `pnpm --filter @paperclipai/db typecheck`
- `pnpm exec vitest run server/src/__tests__/issues-service.test.ts`
- `pnpm exec vitest run server/src/__tests__/issues-service.test.ts -t
"lists persisted decompositions with child issue summaries"`
- `pnpm exec vitest run server/src/__tests__/issues-service.test.ts -t
"accepted plan decomposition"
server/src/__tests__/heartbeat-accepted-plan-workspace-refresh.test.ts
server/src/__tests__/heartbeat-context-summary.test.ts`
- Manual UI path: create a planning issue without an isolated execution
workspace, add a `plan` document, accept the `request_confirmation`, let
Paperclip create child issues, then reopen the parent issue detail page
and confirm the `Plan decomposition` section shows the accepted
revision, status, idempotent-claim badge, and child links.
- Separate follow-up bug noted during manual UI validation: accepting a
plan on an issue whose run never records `workspace_finalize` is tracked
in `PAPA-445` and is not part of this PR’s fix scope.
## Risks
- This adds a new migration and a large Drizzle snapshot update;
reviewers should confirm the schema shape and generated metadata match
the intended decomposition table.
- The exact-once claim changes sit on the accepted-plan fan-out path, so
regressions there could block legitimate child creation or mis-handle
retries if the claim state machine is wrong.
- The new UI only appears when decomposition records exist; reviewers
should use the manual verification path above rather than expecting
existing issues on a stale local instance to show the section
automatically.
- `PAPA-445` remains an open follow-up for the `workspace_finalize`
accept gate when a planning handoff never records finalize; that bug can
interfere with reproducing the UI flow on isolated workspaces but does
not change the correctness of the exact-once decomposition feature
itself.
> Checked `ROADMAP.md`: this PR is a bug fix / control-plane hardening
change for accepted-plan decomposition, not a new uncoordinated roadmap
feature.
## Model Used
- OpenAI Codex via Paperclip `codex_local` (GPT-5-based coding agent;
exact backend model ID/context window not exposed in the run context),
with repository tool use, shell execution, and code-editing
capabilities.

## Thinking Path
> - Paperclip is the control plane for AI-agent companies.
> - Operators need a path to move local company state toward Paperclip
Cloud without losing local-first control.
> - The Cloud Upstream flow needs API, persistence, CLI, and board UI
surfaces that agree on the same manifest/run model.
> - The existing branch had the feature work plus UX and error-handling
follow-ups.
> - This pull request packages the remaining Cloud Upstream sync work
into one standalone branch.
> - The benefit is an inspectable local-to-cloud sync workflow with
preview, conflicts, activation, and captured UX review states.
## What Changed
- Added Cloud Upstream shared types, server routes/services, and
persisted run schema/migration.
- Added Paperclip Cloud CLI sync helpers and local connection storage.
- Added the Cloud Upstream board UI, settings entry points, query keys,
and UX lab page.
- Added preview/activation checklist behavior, redirect handling,
manifest-only preview support, friendly errors, in-flight hints, and
entity count summaries.
## Verification
- `pnpm --filter @paperclipai/plugin-sdk build`
- `NODE_ENV=test pnpm exec vitest run cli/src/__tests__/cloud.test.ts
server/src/__tests__/instance-settings-routes.test.ts
server/src/__tests__/instance-settings-service.test.ts
ui/src/pages/CloudUpstream.test.tsx
ui/src/components/CompanySettingsSidebar.test.tsx`
- `NODE_ENV=test pnpm exec vitest run
server/src/__tests__/cloud-upstreams.test.ts`
Worktree setup note: the isolated worktree install skipped native sqlite
build scripts, so I copied the already-built local sqlite binding from
the main checkout before running
`server/src/__tests__/cloud-upstreams.test.ts`. The test then passed.
## Risks
- Medium: this adds a database migration and a broad feature path across
CLI/server/UI.
- Merge order: this is the only PR in this split with a DB migration;
merge it before any future Cloud Upstream migration follow-up.
- Mitigation: the PR is based directly on current `origin/master`, has
targeted route/service/UI tests, and keeps the feature behind existing
experimental Cloud Sync settings.

## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies, so issue
threads are a core operator surface for reviewing work.
> - The issue detail page is the place where humans read agent messages,
user comments, and execution context together.
> - That thread originally rendered oldest-first, which made recent
activity harder to see during active review.
> - Reversing the thread order changes navigation expectations,
timestamp placement, and the "Jump to latest" affordance, so the UI
behavior needed to move as a coherent set.
> - Because this is a visible core-product behavior shift, it also
needed a safe rollout path instead of becoming the default immediately.
> - This pull request adds the newest-first issue thread behavior behind
an Experimental setting, updates the thread UI to match that mode, and
keeps the legacy oldest-first experience unchanged by default.
> - The benefit is that reviewers can opt into a more recent-first issue
workflow without forcing a global behavior change on every Paperclip
instance.
## What Changed
- Reversed issue thread rendering so the newest comments and messages
appear first when the experiment is enabled.
- Moved the plain comment timestamp into the card header in newest-first
mode and kept the legacy timestamp placement for oldest-first mode.
- Moved the `Jump to latest` control to the bottom of the thread in
newest-first mode while leaving the existing top placement for the
legacy mode.
- Added the `Enable Newest-First Issue Thread` experimental instance
setting and wired issue detail to read that toggle.
- Added regression coverage for thread order, timestamp placement,
jump-button placement, and the issue-detail experiment toggle behavior.
## Verification
- `pnpm -r typecheck`
- `pnpm test:run`
- `pnpm build`
- Focused checks that also passed during issue review:
- `pnpm vitest run src/components/IssueChatThread.test.tsx
src/pages/IssueDetail.test.tsx` in `ui/`
- `pnpm vitest run src/__tests__/instance-settings-routes.test.ts` in
`server/`
- Manual review path:
- Enable `Instance Settings > Experimental > Enable Newest-First Issue
Thread`
- Open an issue with comments/messages and confirm newest activity
renders first, timestamps move into the header, and `Jump to latest`
sits below the thread
- Disable the experiment and confirm the legacy oldest-first behavior
returns
## Risks
- Low risk: the behavioral change is gated behind an instance-level
experimental toggle and defaults off.
- The main regression risk is thread navigation drift between the two
modes, especially around anchor scrolling and the `Jump to latest`
affordance.
- There is some UI coupling between issue-detail query state and
experimental settings fetches, so future changes in that area should
keep both modes covered.
- Screenshots are not attached in this PR body; verification is
described with automated coverage and manual steps instead.
> I checked [`ROADMAP.md`](ROADMAP.md). This is a scoped issue-thread UX
improvement and rollout gate, not a duplicate of a roadmap-level planned
core feature.
## Model Used

GPT-5-based coding agent with terminal tool use and local code execution
in this repository worktree.

## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies.
> - Heartbeat liveness recovery decides when stalled issue trees need
manager-visible follow-up.
> - Automatic recovery issue creation is useful, but operators need
instance-level controls for how aggressive it is.
> - Without controls, recovery behavior is harder to tune for local
development, production operations, and noisy edge cases.
> - This pull request adds configurable liveness auto-recovery settings
across shared contracts, API routes, services, and the instance
experimental settings UI.
> - The benefit is that operators can keep liveness findings advisory or
enable bounded recovery automation with explicit intervals and lookback
windows.
## What Changed
- Added shared types and validators for liveness auto-recovery settings.
- Extended instance settings routes and services to persist and validate
the new controls.
- Wired heartbeat/recovery services to honor enablement, minimum
interval, and lookback settings.
- Added UI controls for liveness recovery under instance experimental
settings.
- Covered the new server behavior with instance settings and liveness
escalation tests.
## Verification
- `pnpm exec vitest run --project @paperclipai/server
server/src/__tests__/heartbeat-issue-liveness-escalation.test.ts
server/src/__tests__/instance-settings-routes.test.ts --pool=forks
--poolOptions.forks.isolate=true`
- `pnpm --filter @paperclipai/shared typecheck`
- `pnpm --filter @paperclipai/server typecheck`
- `pnpm --filter @paperclipai/ui typecheck`
## Risks
- Moderate behavioral risk because recovery automation timing changes
when enabled; defaults keep existing advisory behavior unless the
setting is turned on.
- No database migration in this PR; settings are stored through the
existing instance settings path.

## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies
> - The environments subsystem already models execution environments,
but before this branch there was no end-to-end SSH-backed runtime path
for agents to actually run work against a remote box
> - That meant agents could be configured around environment concepts
without a reliable way to execute adapter sessions remotely, sync
workspace state, and preserve run context across supported adapters
> - We also need environment selection to participate in normal
Paperclip control-plane behavior: agent defaults, project/issue
selection, route validation, and environment probing
> - Because this capability is still experimental, the UI surface should
be easy to hide and easy to remove later without undoing the underlying
implementation
> - This pull request adds SSH environment execution support across the
runtime, adapters, routes, schema, and tests, then puts the visible
environment-management UI behind an experimental flag
> - The benefit is that we can validate real SSH-backed agent execution
now while keeping the user-facing controls safely gated until the
feature is ready to come out of experimentation
## What Changed
- Added SSH-backed execution target support in the shared adapter
runtime, including remote workspace preparation, skill/runtime asset
sync, remote session handling, and workspace restore behavior after
runs.
- Added SSH execution coverage for supported local adapters, plus remote
execution tests across Claude, Codex, Cursor, Gemini, OpenCode, and Pi.
- Added environment selection and environment-management backend support
needed for SSH execution, including route/service work, validation,
probing, and agent default environment persistence.
- Added CLI support for SSH environment lab verification and updated
related docs/tests.
- Added the `enableEnvironments` experimental flag and gated the
environment UI behind it on company settings, agent configuration, and
project configuration surfaces.
## Verification
- `pnpm exec vitest run
packages/adapters/claude-local/src/server/execute.remote.test.ts
packages/adapters/cursor-local/src/server/execute.remote.test.ts
packages/adapters/gemini-local/src/server/execute.remote.test.ts

ui/src/lib/new-agent-runtime-config.test.ts`
- `pnpm -r typecheck`
- `pnpm build`
- Manual verification on a branch-local dev server:
- enabled the experimental flag
- created an SSH environment
- created a Linux Claude agent using that environment
- confirmed a run executed on the Linux box and synced workspace changes
back
## Risks
- Medium: this touches runtime execution flow across multiple adapters,
so regressions would likely show up in remote session setup, workspace
sync, or environment selection precedence.
- The UI flag reduces exposure, but the underlying runtime and route
changes are still substantial and rely on migration correctness.
- The change set is broad across adapters, control-plane services,
migrations, and UI gating, so review should pay close attention to
environment-selection precedence and remote workspace lifecycle
behavior.
## Model Used
- OpenAI Codex via Paperclip's local Codex adapter, GPT-5-class coding
model with tool use and code execution in the local repo workspace. The
local adapter does not surface a more specific public model version
string in this branch workflow.

## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies.
> - The heartbeat runtime, agent import path, and agent configuration
defaults determine whether work is dispatched safely and predictably.
> - Several accumulated fixes all touched agent execution recovery, wake
routing, import behavior, and runtime concurrency defaults.
> - Those changes need to land together so the heartbeat service and
agent creation defaults stay internally consistent.
> - This pull request groups the runtime/governance changes from the
split branch into one standalone branch.
> - The benefit is safer recovery for stranded runs, bounded high-volume
reads, imported-agent approval correctness, skill-template support, and
a clearer default concurrency policy.
## What Changed
- Fixed stranded continuation recovery so successful automatic retries
are requeued instead of incorrectly blocking the issue.
- Bounded high-volume issue/log reads across issue, heartbeat, agent,
project, and workspace paths.
- Fixed imported-agent approval and instruction-path permission
handling.
- Quarantined seeded worktree execution state during worktree
provisioning.
- Queued approval follow-up wakes and hardened SQL_ASCII heartbeat
output handling.
- Added reusable agent instruction templates for hiring flows.
- Set the default max concurrent agent runs to five and updated related
UI/tests/docs.

- Split integration check: merged this branch first, followed by the
other [PAP-1614](/PAP/issues/PAP-1614) branches, with no merge
conflicts.
- Confirmed this branch does not include `pnpm-lock.yaml`.
## Risks
- Medium risk: touches heartbeat recovery, queueing, and issue list
bounds in central runtime paths.
- Imported-agent and concurrency default behavior changes may affect
existing automation that assumes one-at-a-time default runs.
- No database migrations are included.

Replace single retentionDays with a three-tier BackupRetentionPolicy:
- Daily: keep all backups (presets: 3, 7, 14 days; default 7)
- Weekly: keep one per calendar week (presets: 1, 2, 4 weeks; default 4)
- Monthly: keep one per calendar month (presets: 1, 3, 6 months; default 1)
Pruning sorts backups newest-first and applies each tier's cutoff,
keeping only the newest entry per ISO week/month bucket. The Instance
Settings General page now shows three preset selectors (no icon, matches
existing page design). Remove Database icon import.
Compress database backups with gzip (.sql.gz), reducing file size ~83%.
Add backup retention configuration to Instance Settings UI with preset
options (7 days, 2 weeks, 1 month). The backup scheduler now reads
retention from the database on each tick so changes take effect without
restart. Default retention changed from 30 to 7 days.
Introduce a singleton instance_settings store and experimental settings API, add the Experimental instance settings page, and gate execution workspace behavior behind the new enableIsolatedWorkspaces flag.
