Devin Foley	0a95ada1be	feat(server): chunked import preview endpoint and resumable upload in the Import page and CLI (#11224 ) ## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work > - The previous pull request added server-side chunked resumable import transfers; without clients, large imports still ride the single fragile upload > - The Import page and the CLI need to slice large packages, upload parts with retry and progress, resume after interruptions, and preview before applying > - Preview is the missing server piece: the browser flow is preview-then-import, so a completed spool must be previewable without re-uploading > - This pull request adds the transfer preview endpoint, switches the Import page to the chunked path for zips over 48 MB, and teaches the CLI the same for oversized local imports > - The benefit is that large imports get progress, per-part retry, and resume in both clients, while small imports keep the exact single-shot path they have today ## Linked Issues or Issue Description What happened? With only the server transfer routes in place, users still upload large company packages as one request from the Import page and the CLI: no progress indication, no retry below the whole file, and no resume after a dropped connection or refresh. The preview-then-import flow also cannot run against an uploaded transfer, forcing a second full upload. Expected behavior A large package uploads once as verified parts with visible progress; preview and import both run against the uploaded spool; an interrupted upload resumes with only the missing parts re-sent; packages at or below 48 MB behave exactly as before. Steps to reproduce 1. Select a 500 MB zip on the Import page over an unreliable connection. 2. Watch the single upload fail near the end and restart from zero, twice — once for preview, once for import. 3. Same story headless via the CLI. ## What Changed - Server: `POST /import/transfers/:id/preview` runs the existing preview logic against the completed spool (shared assembly + whole-file verification helper with apply); preview neither completes the run nor deletes the spool, so the subsequent apply reuses it. Missing parts respond with the missing list. - UI: zips over 48 MB take the chunked path in both preview and import — the file is sliced into 32 MB parts hashed with WebCrypto (single ArrayBuffer, no second copy), the transfer is created or resumed (the create response's missing-parts list drives what uploads), parts upload sequentially with three attempts each and visible progress, then transfer preview/apply replace the multipart calls. The existing preview pane, collision handling, adapter overrides, and async job polling are unchanged; ≤ 48 MB keeps the single-shot path. - CLI: oversized local `.zip` or folder imports zip/slice/hash with node crypto, upload with resume and per-part retry and progress lines, and use transfer preview/apply. Small packages keep the inline path byte-identical. - Failure honesty: adapters/API errors fail open to existing behavior; a part failing all attempts surfaces a durable error panel with resume intact. ## Verification - Server: preview-then-apply on one spool (run stays open, spool intact, then apply completes), preview with missing parts rejected — added to the transfer route suite (embedded Postgres). - UI suite: large file takes the chunked path (manifest shape, part uploads, progress, apply on a resumed transfer, single-shot endpoints never called), small file stays single-shot, part failure after three attempts surfaces the error panel without running preview, resume re-uploads only the missing part. - CLI: manifest slicing/hashing, threshold behavior for zip and folder sources, folder-zip round-trip through the real zip reader, upload resume/retry/exhaustion/already-completed, full-command chunked and small-zip inline flows. - Server, ui, cli typechecks clean. Exact counts in the PR checks. ## Risks - The 48 MB threshold only routes between two verified paths; behavior below it is untouched. - Chunked CLI imports use the board-scoped transfer routes, so oversized CLI imports need board credentials (agent tokens keep the agent-safe small-file path). No privilege change — board actors already had the generic routes — but the two size regimes differ semantically; called out for review. - A CLI dry-run over the threshold uploads parts before previewing; the spool persists (24 h sweep) and a later apply resumes without re-upload — inherent to preview-against-spool. Stacked on #11223 — merge that first; this PR then shows only the preview endpoint and client changes. ## Model Used - Claude Fable 5 (`claude-fable-5`) via Claude Code CLI, with extended thinking and tool use (multi-agent implementation with independent verification). ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [ ] All Paperclip CI gates are green - [ ] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge	2026-08-11 16:06:37 -07:00

A company import fails at the preview step with `Preview failed: Import package exceeds 134217728 bytes`. The package is a valid Paperclip export. Its compressed size is larger than the 128 MB server cap (one reported package is 257 MB). The error panel suggests the CLI folder import, but that path sends the package as one inline JSON body capped at 64 MB, so it also fails. Expected behavior A valid company package of realistic size imports successfully through the Import page. If a package is too large, the error must state the limit clearly and suggest a step that can work. Steps to reproduce 1. Export a company with enough attachments to make the compressed package larger than 128 MB. 2. Open the Import page and upload the `.zip`. 3. Click "Preview import". 4. The preview fails with `Import package exceeds 134217728 bytes`. Deployment mode Reported from a managed deployment; the limit applies to all deployment modes. ## What Changed - Raise `PORTABLE_ZIP_UPLOAD_LIMIT_BYTES` from 128 MB to a 1 GB default (`server/src/http/body-limits.ts`). - Add the `PAPERCLIP_IMPORT_ZIP_MAX_BYTES` environment override. Invalid or non-positive values fall back to the default. - Scale the zip decompression-bomb guard from the configured cap at the import route: the aggregate inflated ceiling is 4x the cap. The per-entry ceiling stays at 512 MB because V8's string length limit applies to an entry regardless (`server/src/routes/companies.ts`, `packages/shared/src/portability-zip.ts`). - Report the 422 limit error in MB instead of raw bytes. - Replace the "use the CLI folder import for very large packages" hint on preview failure with advice that works: re-export the package without large attachments (`ui/src/pages/CompanyImport.tsx`). - Update the stale comment in `ui/src/lib/import-preflight.ts` that made the same CLI claim. - Add tests for the new default, the env override, and the invalid-override fallback. ## Verification - `pnpm vitest run server/src/__tests__/body-limits.test.ts packages/shared/src/portability-zip.test.ts server/src/__tests__/company-portability-routes.test.ts server/src/__tests__/company-portability.test.ts server/src/__tests__/company-portability-import-batching.test.ts` — all pass. - `pnpm vitest run ui/src/pages/CompanyImport.test.tsx` — passes, including the updated failure-panel copy assertion. - `pnpm typecheck` — clean across the workspace. - Manual: upload a `.zip` larger than the configured cap; the preview fails with `Import package exceeds the 1024 MB upload limit` and the new hint. A package between 128 MB and 1 GB now previews and imports. ## Risks - Peak per-import memory rises with the cap: the upload is buffered in memory and unzipped in one pass. A 1 GB compressed package can use several GB transiently. Imports are instance-admin actions, so the exposure is a deliberate operator action, not anonymous traffic. Operators on small hosts can lower the cap with `PAPERCLIP_IMPORT_ZIP_MAX_BYTES`. - The aggregate bomb guard moves from a fixed 512 MB to 4x the configured cap. It still bounds expansion far below what a decompression bomb needs. - No migration and no API shape change. The 422 message text changes; no code matches on the old text. ## Model Used - Claude Fable 5 (`claude-fable-5`) via Claude Code CLI, with extended thinking and tool use (file edits, local test runs, live-instance inspection). ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [ ] All Paperclip CI gates are green - [ ] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge	2026-08-10 12:47:03 -07:00
Devin Foley	916c13501f	Replace host-to-host Cloud Sync with full-fidelity company Import/Export (#10507 ) ## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work > - A company accumulates real state — issues, labels, blockers, documents, work products, monitors, attachments, agents, routines — and people need to move that state between instances: self-hosted to cloud, cloud back to self-hosted, or plain backups > - The experimental, flag-gated Cloud Sync transport (#6548) tried to solve this host-to-host: the source pushed into a receiver over HTTPS with a cross-instance consent/token handshake, which required the destination to be publicly reachable and broke for common self-hosted topologies (plain-HTTP LAN/VPN origins); the receiver half never landed upstream at all > - Meanwhile the portability bundle and the existing export/import pages already move companies offline with none of those networking constraints — but silently dropped labels, blockers, issue documents, work products, monitors, and every attachment > - This pull request removes the host-to-host transport and makes Import/Export the single data-movement path: the pages become first-class company-settings destinations, exports declare exactly what they do not carry, and bundle schemaVersion 6 now carries all of the above, with attachments as content-addressed sha256 blobs verified before a single row is written > - The benefit is a migration and backup flow that works between any two instances with no reachability requirements, no cross-instance auth, and no silent data loss ## Linked Issues or Issue Description - Refs #6548 — the original Cloud Sync sender this PR supersedes and removes. - Related, not duplicates: #1697 (goals in the portability manifest — orthogonal field addition), #954 (an earlier import/export + skill-visibility proposal predating the current portability bundle). - No open issue describes this directly, so in brief (feature-request shape): Problem — moving a company between instances silently lost labels (imports with label references actually hard-failed), blocker relations, issue documents, work products, monitor state, and all attachments, and the alternative Cloud Sync transport required the destination to be publicly reachable over HTTPS plus a consent handshake, which failed for typical self-hosted setups. Desired behavior — one Import/Export flow in company settings that produces a portable bundle carrying all of that data, tells the operator up front what it cannot carry, imports with automations paused, and offers real one-click activation afterwards. ## What Changed - New export fidelity report (`GET /api/companies/:companyId/export/fidelity`) + an "Export fidelity" panel on the Export page listing anything a bundle will not include (now only: approvals, cost history, activity history) - Imports accept `pauseAutomations`; imported agents and routines land paused, the import result reports created routines, and the Import page ends in an activation panel that actually resumes selected agents/activates routines - Export and Import pages promoted into the company-settings nav; the Cloud Upstream wizard, ux-lab page, and API client removed; the old settings route redirects to Export - Host-to-host transport removed: upstream-sync/receiver-client routes and services, CLI `cloud connect`/`cloud push` + keypair store, the shared upstream transfer contract, and the `enableCloudSync` flag; migration `0196` drops the two experimental `cloud_upstream_` sender tables - Bundle schemaVersion 6: labels (definitions + per-task names, remapped by name on import), blocker relations (`blockedBy` slugs, cycle-tolerant), issue documents (`tasks/<slug>/documents/<key>.md`), work products (system refs nulled), monitors (notes/scheduledBy restored, imported un-armed) - Attachments travel as content-addressed `blobs/<sha256>` entries (deduped; comment-scoped attachments re-link via comment index); every blob is hash-verified before any write, so a corrupted bundle cannot leave a partially imported company; both zip codecs now round-trip extensionless/binary entries byte-exactly; the Import page preflights the inline body limit and offers continue-without-attachments - v5 (and older) bundles still import, with an informational warning; bundles newer than v6 are rejected cleanly - Docs: board-operator import/export guide, CLI README, README/ROADMAP updated ## Verification - `pnpm -r` typechecks (shared, db incl. migration numbering/safety checks, server, ui, cli) and `pnpm check:token-gates` — clean - Vitest: full server + shared sweep 4,888 passed / 1 skipped, with the only 3 failures being pre-existing on `master` (2× heartbeat-workspace-branch-containment, 1× workspace-runtime auto-port; reproduced identically with this change stashed); ui + cli suites green; the embedded-Postgres export-fidelity suite applies the full migration chain including the new `0196` against a fresh database - Live end-to-end on a scratch instance: seeded a company with labels, a blocker pair, an issue document, a work product, a monitor, an agent, a routine, and two binary attachments (one comment-scoped) → export → import into a fresh company → labels remapped to new ids, blocker edge and document restored, monitor un-armed with notes intact, attachments byte-identical (sha256-compared through the API), agents/routines paused → activation panel resumed them; a v5-shaped bundle imported with only the info warning; flipping one byte in a blob made the import 422 with zero* rows created - Reviewer repro: create a company with a labeled issue + attachment → Settings → Export → download → Settings → Import on another company/instance → watch the preview, apply with "start paused", then activate ## Risks - Migration `0196` drops `cloud_upstream_connections`/`cloud_upstream_runs` — experimental tables behind a default-off flag; their connection/run history is intentionally discarded - Breaking removals are all of experimental, flag-gated surface: `/api/upstream-sync/` + `/api/cloud-upstreams/` routes, `paperclipai cloud connect\|push`, and the `enableCloudSync` flag (stale keys in stored instance settings parse harmlessly) - Import remains non-atomic on mid-apply errors generally (pre-existing behavior); the new blob verification specifically moved ahead of all writes so tampered bundles cannot create partial state - GitHub-sourced imports do not fetch `blobs/*` and skip attachments with a warning ## Model Used - Claude Fable 5 (`claude-fable-5`, Anthropic), via Claude Code CLI with extended thinking, tool use, and subagent orchestration; implementation and review split across Fable 5 subagents, with live end-to-end verification against a running instance ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [ ] All Paperclip CI gates are green - [ ] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge	2026-07-30 11:37:00 -07:00

feat(server): chunked import preview endpoint and resumable upload in the Import page and CLI (#11224 )

## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - The previous pull request added server-side chunked resumable import
transfers; without clients, large imports still ride the single fragile
upload
> - The Import page and the CLI need to slice large packages, upload
parts with retry and progress, resume after interruptions, and preview
before applying
> - Preview is the missing server piece: the browser flow is
preview-then-import, so a completed spool must be previewable without
re-uploading
> - This pull request adds the transfer preview endpoint, switches the
Import page to the chunked path for zips over 48 MB, and teaches the CLI
the same for oversized local imports
> - The benefit is that large imports get progress, per-part retry, and
resume in both clients, while small imports keep the exact single-shot
path they have today

## Linked Issues or Issue Description

**What happened?**

With only the server transfer routes in place, users still upload large
company packages as one request from the Import page and the CLI: no
progress indication, no retry below the whole file, and no resume after
a dropped connection or refresh. The preview-then-import flow also
cannot run against an uploaded transfer, forcing a second full upload.

**Expected behavior**

A large package uploads once as verified parts with visible progress;
preview and import both run against the uploaded spool; an interrupted
upload resumes with only the missing parts re-sent; packages at or below
48 MB behave exactly as before.

**Steps to reproduce**

1. Select a 500 MB zip on the Import page over an unreliable connection.
2. Watch the single upload fail near the end and restart from zero,
twice — once for preview, once for import.
3. Same story headless via the CLI.

## What Changed

- Server: `POST /import/transfers/:id/preview` runs the existing preview
logic against the completed spool (shared assembly + whole-file
verification helper with apply); preview neither completes the run nor
deletes the spool, so the subsequent apply reuses it. Missing parts
respond with the missing list.
- UI: zips over 48 MB take the chunked path in both preview and import —
the file is sliced into 32 MB parts hashed with WebCrypto (single
ArrayBuffer, no second copy), the transfer is created or resumed (the
create response's missing-parts list drives what uploads), parts upload
sequentially with three attempts each and visible progress, then
transfer preview/apply replace the multipart calls. The existing preview
pane, collision handling, adapter overrides, and async job polling are
unchanged; ≤ 48 MB keeps the single-shot path.
- CLI: oversized local `.zip` or folder imports zip/slice/hash with node
crypto, upload with resume and per-part retry and progress lines, and
use transfer preview/apply. Small packages keep the inline path
byte-identical.
- Failure honesty: adapters/API errors fail open to existing behavior; a
part failing all attempts surfaces a durable error panel with resume
intact.

## Verification

- Server: preview-then-apply on one spool (run stays open, spool intact,
then apply completes), preview with missing parts rejected — added to
the transfer route suite (embedded Postgres).
- UI suite: large file takes the chunked path (manifest shape, part
uploads, progress, apply on a resumed transfer, single-shot endpoints
never called), small file stays single-shot, part failure after three
attempts surfaces the error panel without running preview, resume
re-uploads only the missing part.
- CLI: manifest slicing/hashing, threshold behavior for zip and folder
sources, folder-zip round-trip through the real zip reader, upload
resume/retry/exhaustion/already-completed, full-command chunked and
small-zip inline flows.
- Server, ui, cli typechecks clean. Exact counts in the PR checks.

## Risks

- The 48 MB threshold only routes between two verified paths; behavior
below it is untouched.
- Chunked CLI imports use the board-scoped transfer routes, so oversized
CLI imports need board credentials (agent tokens keep the agent-safe
small-file path). No privilege change — board actors already had the
generic routes — but the two size regimes differ semantically; called
out for review.
- A CLI dry-run over the threshold uploads parts before previewing; the
spool persists (24 h sweep) and a later apply resumes without re-upload
— inherent to preview-against-spool.

Stacked on #11223 — merge that first; this PR then shows only the
preview endpoint and client changes.

fix(server): raise company import zip upload limit to 1 GB and make it operator-configurable (#11184 )

## Thinking Path

between instances, with the Import page uploading the package as one
compressed `.zip`
> - The server caps that upload at 128 MB, and real company packages

## Linked Issues or Issue Description

**What happened?**

A company import fails at the preview step with `Preview failed: Import
package exceeds 134217728 bytes`. The package is a valid Paperclip
export. Its compressed size is larger than the 128 MB server cap (one
reported package is 257 MB). The error panel suggests the CLI folder
import, but that path sends the package as one inline JSON body capped
at 64 MB, so it also fails.

**Expected behavior**

A valid company package of realistic size imports successfully through
the Import page. If a package is too large, the error must state the
limit clearly and suggest a step that can work.

**Steps to reproduce**

1. Export a company with enough attachments to make the compressed
package larger than 128 MB.
2. Open the Import page and upload the `.zip`.
3. Click "Preview import".
4. The preview fails with `Import package exceeds 134217728 bytes`.

**Deployment mode**

Reported from a managed deployment; the limit applies to all deployment
modes.

## What Changed

- Raise `PORTABLE_ZIP_UPLOAD_LIMIT_BYTES` from 128 MB to a 1 GB default
(`server/src/http/body-limits.ts`).
- Add the `PAPERCLIP_IMPORT_ZIP_MAX_BYTES` environment override. Invalid
or non-positive values fall back to the default.
- Scale the zip decompression-bomb guard from the configured cap at the
import route: the aggregate inflated ceiling is 4x the cap. The
per-entry ceiling stays at 512 MB because V8's string length limit
applies to an entry regardless (`server/src/routes/companies.ts`,
`packages/shared/src/portability-zip.ts`).
- Report the 422 limit error in MB instead of raw bytes.
- Replace the "use the CLI folder import for very large packages" hint
on preview failure with advice that works: re-export the package without
large attachments (`ui/src/pages/CompanyImport.tsx`).
- Update the stale comment in `ui/src/lib/import-preflight.ts` that made
the same CLI claim.
- Add tests for the new default, the env override, and the
invalid-override fallback.

## Verification

- `pnpm vitest run server/src/__tests__/body-limits.test.ts
packages/shared/src/portability-zip.test.ts
server/src/__tests__/company-portability-routes.test.ts
server/src/__tests__/company-portability.test.ts
server/src/__tests__/company-portability-import-batching.test.ts` — all
pass.
- `pnpm vitest run ui/src/pages/CompanyImport.test.tsx` — passes,
including the updated failure-panel copy assertion.
- `pnpm typecheck` — clean across the workspace.
- Manual: upload a `.zip` larger than the configured cap; the preview
fails with `Import package exceeds the 1024 MB upload limit` and the new
hint. A package between 128 MB and 1 GB now previews and imports.

## Risks

- Peak per-import memory rises with the cap: the upload is buffered in
memory and unzipped in one pass. A 1 GB compressed package can use
several GB transiently. Imports are instance-admin actions, so the
exposure is a deliberate operator action, not anonymous traffic.
Operators on small hosts can lower the cap with
`PAPERCLIP_IMPORT_ZIP_MAX_BYTES`.
- The aggregate bomb guard moves from a fixed 512 MB to 4x the
configured cap. It still bounds expansion far below what a decompression
bomb needs.
- No migration and no API shape change. The 422 message text changes; no
code matches on the old text.

## Model Used

- Claude Fable 5 (`claude-fable-5`) via Claude Code CLI, with extended
thinking and tool use (file edits, local test runs, live-instance
inspection).

Replace host-to-host Cloud Sync with full-fidelity company Import/Export (#10507 )

## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - A company accumulates real state — issues, labels, blockers,
documents, work products, monitors, attachments, agents, routines — and
people need to move that state between instances: self-hosted to cloud,
cloud back to self-hosted, or plain backups
> - The experimental, flag-gated Cloud Sync transport (#6548) tried to
solve this host-to-host: the source pushed into a receiver over HTTPS
with a cross-instance consent/token handshake, which required the
destination to be publicly reachable and broke for common self-hosted
topologies (plain-HTTP LAN/VPN origins); the receiver half never landed
upstream at all
> - Meanwhile the portability bundle and the existing export/import
pages already move companies offline with none of those networking
constraints — but silently dropped labels, blockers, issue documents,
work products, monitors, and every attachment
> - This pull request removes the host-to-host transport and makes
Import/Export the single data-movement path: the pages become
first-class company-settings destinations, exports declare exactly what
they do not carry, and bundle schemaVersion 6 now carries all of the
above, with attachments as content-addressed sha256 blobs verified
before a single row is written

two instances with no reachability requirements, no cross-instance auth,
and no silent data loss

## Linked Issues or Issue Description

- Refs #6548 — the original Cloud Sync sender this PR supersedes and
removes.
- Related, not duplicates: #1697 (goals in the portability manifest —
orthogonal field addition), #954 (an earlier import/export +
skill-visibility proposal predating the current portability bundle).
- No open issue describes this directly, so in brief (feature-request
shape): **Problem** — moving a company between instances silently lost
labels (imports with label references actually hard-failed), blocker
relations, issue documents, work products, monitor state, and all
attachments, and the alternative Cloud Sync transport required the
destination to be publicly reachable over HTTPS plus a consent
handshake, which failed for typical self-hosted setups. **Desired
behavior** — one Import/Export flow in company settings that produces a
portable bundle carrying all of that data, tells the operator up front
what it cannot carry, imports with automations paused, and offers real
one-click activation afterwards.

## What Changed

- New export fidelity report (`GET
/api/companies/:companyId/export/fidelity`) + an "Export fidelity" panel
on the Export page listing anything a bundle will not include (now only:
approvals, cost history, activity history)
- Imports accept `pauseAutomations`; imported agents and routines land
paused, the import result reports created routines, and the Import page
ends in an activation panel that actually resumes selected
agents/activates routines
- Export and Import pages promoted into the company-settings nav; the
Cloud Upstream wizard, ux-lab page, and API client removed; the old
settings route redirects to Export
- Host-to-host transport removed: upstream-sync/receiver-client routes
and services, CLI `cloud connect`/`cloud push` + keypair store, the
shared upstream transfer contract, and the `enableCloudSync` flag;
migration `0196` drops the two experimental `cloud_upstream_*` sender
tables
- Bundle schemaVersion 6: labels (definitions + per-task names, remapped
by name on import), blocker relations (`blockedBy` slugs,
cycle-tolerant), issue documents (`tasks/<slug>/documents/<key>.md`),
work products (system refs nulled), monitors (notes/scheduledBy
restored, imported un-armed)
- Attachments travel as content-addressed `blobs/<sha256>` entries
(deduped; comment-scoped attachments re-link via comment index); every
blob is hash-verified **before any write**, so a corrupted bundle cannot
leave a partially imported company; both zip codecs now round-trip
extensionless/binary entries byte-exactly; the Import page preflights
the inline body limit and offers continue-without-attachments
- v5 (and older) bundles still import, with an informational warning;
bundles newer than v6 are rejected cleanly
- Docs: board-operator import/export guide, CLI README, README/ROADMAP
updated

## Verification

- `pnpm -r` typechecks (shared, db incl. migration numbering/safety
checks, server, ui, cli) and `pnpm check:token-gates` — clean
- Vitest: full server + shared sweep 4,888 passed / 1 skipped, with the
only 3 failures being pre-existing on `master` (2×
heartbeat-workspace-branch-containment, 1× workspace-runtime auto-port;
reproduced identically with this change stashed); ui + cli suites green;
the embedded-Postgres export-fidelity suite applies the full migration
chain including the new `0196` against a fresh database
- Live end-to-end on a scratch instance: seeded a company with labels, a
blocker pair, an issue document, a work product, a monitor, an agent, a
routine, and two binary attachments (one comment-scoped) → export →
import into a fresh company → labels remapped to new ids, blocker edge
and document restored, monitor un-armed with notes intact, attachments
byte-identical (sha256-compared through the API), agents/routines paused
→ activation panel resumed them; a v5-shaped bundle imported with only
the info warning; flipping one byte in a blob made the import 422 with
**zero** rows created
- Reviewer repro: create a company with a labeled issue + attachment →
Settings → Export → download → Settings → Import on another
company/instance → watch the preview, apply with "start paused", then
activate

## Risks

- Migration `0196` drops
`cloud_upstream_connections`/`cloud_upstream_runs` — experimental tables
behind a default-off flag; their connection/run history is intentionally
discarded
- Breaking removals are all of experimental, flag-gated surface:
`/api/upstream-sync/*` + `/api/cloud-upstreams/*` routes, `paperclipai
cloud connect|push`, and the `enableCloudSync` flag (stale keys in
stored instance settings parse harmlessly)
- Import remains non-atomic on mid-apply errors generally (pre-existing
behavior); the new blob verification specifically moved ahead of all
writes so tampered bundles cannot create partial state
- GitHub-sourced imports do not fetch `blobs/*` and skip attachments
with a warning

## Model Used

- Claude Fable 5 (`claude-fable-5`, Anthropic), via Claude Code CLI with
extended thinking, tool use, and subagent orchestration; implementation
and review split across Fable 5 subagents, with live end-to-end
verification against a running instance
