## Thinking Path > - Paperclip coordinates agent work and preserves its results. > - Remote execution copies completed workspace changes back to the host. > - An agent can fetch a published branch with shallow Git history. > - A full Git bundle omits the shallow boundary metadata and can fail host connectivity checks. > - This pull request carries the boundaries through the full-bundle fallback and imports through normal Git fetch. > - Recovery must also recognize completed native work on a reusable lease without treating it as ordinary executor reuse. > - Completed work can be saved without another provider turn, while existing host history remains connected. ## Linked Issues or Issue Description **What happened?** Sandbox finalization can fail with a missing parent commit after an agent checks out a separately fetched shallow branch. Re-exporting a full bundle repeats the failure because Git bundles do not encode shallow boundaries. **Expected behavior** Import the completed branch and saved files. Preserve existing host ancestry and concurrent host edits. Keep normal Git connectivity and workspace merge checks. **Steps to reproduce** 1. Prepare a sandbox from one host commit. 2. Fetch a different published branch with depth one and check it out. 3. Save a result file and restore the sandbox workspace. **Paperclip version or commit** Reproduced against master before this repair. The regression fails with the missing-parent error before the production change. Related public context: #15268 covers rewritten history integration. This repair handles shallow bundle transport before integration. Searches found no equivalent open repair. ## What Changed - Export shallow boundaries beside the full bundle when the delta import lacks history. - Unpack into a temporary shared bare repository. Keep parent connections already available on the host and import with Git's shallow fetch protocol. - Reject malformed boundary values and retain existing connectivity, branch, and concurrent-work merge guards. Keep boundary probes within 15 seconds without consuming the separate 60-second Git import budget. - Let source-bound preservation recover reusable leases only for the finalizer-selected, accepted successful native result and matching completion contract. Retain provider-stop, physical ownership and host-writer checks; ordinary reusable sources remain blocked. - Classify invalid Git metadata separately from omittable unsafe archives. Keep native finalization failed and preserve service-owned file recovery; carry the sender's dedicated rejection across the command boundary without transient retries. - Share the failure allowlist across bounded run/activity projections and cancelled-preservation selection. Migration `0416` rebuilds the matching partial index; task chat retains the non-retryable recovery notice. - Add real Git, filesystem sandbox and database recovery regressions. Update execution semantics and affected verification maps. ## Verification - Red: real filesystem sandbox restore failed with the same missing-parent/revision-walk error before the export repair. - Green: 240 focused Git, workspace restore, sandbox transport and native-finalization tests pass. Coverage includes both transfer paths, malformed/oversized metadata, a genuinely shallow host with its original boundary intact, and concurrent host work with both merge parents verified. - Red/green: a 14-second simulated probe left the final real Git fetch only 45,893 ms before the budget split. It now retains over 55 seconds after the probes; a 16-second probe exhausts its own budget before host import. - Red/green: an oversized read progress report was retried three times before its distinct metadata classification. It now aborts the first read before payload consumption, leaves the host tip unchanged and does not retry. - Red/green: the real metadata error was swallowed by best-effort export and native finalization incorrectly returned success. Both regressions now pass; all 240 focused Git/restore/native-finalization tests pass. A PostgreSQL/filesystem fault-injection test also verifies retained files, failed run, service-owned recovery barrier, no preservation receipt and no new wake. - Red/green: duplicate metadata produced 47 Git process starts before deduplication; the bounded-work regression now passes. Oversized byte and boundary inputs fail before Git probes. - Recovery red: both reusable lease policies exhausted recovery despite a selected accepted successful result. The assembled PostgreSQL/filesystem path now passes for retained and both reusable policies, including idempotent re-admission after exhausted automatic recovery, saved files, no agent wake, and once-only existing-result finalization. - Source verification controls reject ordinary reusable leases, rejected/failed/unselected results, another physical allocation owner, and an active host writer without changing recorded state. - The 78-test PostgreSQL/filesystem recovery/source suite passed before the metadata classification correction. Its new persisted metadata-failure regression also passes. Full workspace typecheck and build pass at final head `69f10daab2`. - `node scripts/check-maps.mjs` and `git diff --check` pass. - Full local `pnpm test:run` attempts did not finish. They are not counted as passes. Early focused runs exceeded 5-second and 30-second fixture deadlines; the final serial suite passed all 176 tests with a 30-second per-test budget in 56.8 seconds. - Red/green: both bounded PostgreSQL projections dropped the new code in oversized results. All 19 source/projection cases now pass, plus an actual index-predicate test that excludes a metadata repair hold and still selects ordinary cancelled work. - Red/green: an oversized sender `.git/shallow` lost its error type before host validation. The real transport test now verifies one typed rejection, no shallow-payload read, and an unchanged host tip. All 465 command/sandbox/task-chat tests pass, and token/migration gates pass. - Full typecheck/build pass after these final contract corrections at `69f10daab2`; all 20 PostgreSQL source/projection/index contracts pass. All current-head CI checks passed; Greptile is 5/5 with no unresolved review threads. Merged #18230 supplies the CI-cache and Linux shell-fixture baseline repairs; their duplicate changes have been removed from this PR. The final Runner lane passed after one justified rerun of an unchanged authentication fixture timeout (all 11 fixture tests also pass locally). Previous CI failures and incomplete local runs remain recorded; live deployment and retained-run recovery remain separate verification. ## Risks - The fallback creates a temporary shared bare clone. Metadata is limited to 64 KiB and 256 unique boundaries, duplicate/parent probes are cached, and Git import has a 60-second command budget plus a separate 15-second boundary-probe budget. It runs only after a missing-history import failure. - Incorrect boundaries could hide real host ancestry. The importer retains available parent connections, and regressions cover that case. - The full-bundle fallback can transfer a bundle twice. This preserves the existing fast delta path; removing that extra transfer is outside this correctness repair. - Preservation eligibility expands only for completed native exports on reusable leases. It creates no provider turn and leaves ordinary reusable leases ineligible. Database/filesystem regressions cover result selection and competing physical/host ownership. - The migration rebuilds one partial index; no tables, columns or user records change. There are no agent execution admission, model, trust, recovery permission, workflow or lockfile changes. ## Model Used OpenAI Codex, GPT-6, with reasoning, code execution, and browser tools.

Paperclip maps
The maps describe the same capabilities from two perspectives:
- Feature map: what a person can do, where to reach it, and how to verify the user journey. Preserve its Poteto format.
- Agent access map: the APIs and agent entry points for those capabilities, their permission boundaries, and access verification.
The chat scenario catalog adds natural-language requests, starting context and expected conversational outcomes for the same capability IDs. It lives with Product E2E as planning data; a scenario reference is neither a registered execution nor evidence that a journey passed.
These are sibling directories under maps/. Each feature file has a same-named
agent access companion. Reuse the product map's sub-feature IDs, so tasks/create
identifies the same capability in both maps. Product behavior remains governed by
the implementation spec; a map cannot grant
authority or redefine a permission denial as success.
Capability identifiers
The feature ID is the recipe filename without .md, such as onboarding.
The full capability ID joins that feature ID and a Sub-features key with /:
the company key in feature-map/onboarding.md is onboarding/company.
Its agent-access-map/onboarding.md companion uses the same local company key.
The feature-map index lists the existing
feature and full capability IDs.
Each child page states Feature ID: `onboarding`. after its introduction or
product-map link. In feature recipes, show the full ID beside the parsed local
key: - `company`: `onboarding/company` — create a company. In access
companions and Storybook verification guidance, keep the existing local heading
and put Capability ID: `onboarding/company`. beneath it. These labels make
the existing identifiers visible without changing keys, anchors, or ID generation.
Use full capability IDs in cross-feature references, Storybook annotations, tests, issues, PRs, and verification evidence. Both segments use lowercase letters, digits, and hyphens. Keep filenames and keys stable when display titles or navigation labels change; renaming either changes the capability ID.
Entry-point IDs describe a surface, such as web-wizard, and are scoped to their
recipe. Reference them with a recipe link, such as
onboarding.md#web-wizard, and record the
capability exercised separately. Navigation section labels are not capability IDs.
See IDs and references for examples.
Access contract
Every business operation needs both an API and a usable agent entry point for an
actor authorized to perform it. A dedicated tool is optional when REST, the CLI,
an assigned MCP client, or native search_api / call_api already provides the
operation. Record which agent surfaces actually have that path; an installed CLI
or optional MCP package cannot be assumed available to every native/remote run.
Track these independently:
| Dimension | Values and meaning |
|---|---|
| API | present, missing, not-applicable, or unreviewed. Use exact methods/paths; distinguish protocols from REST. |
| Agent access | available, partial, missing, restricted, operator-only, not-applicable, or unreviewed. Name the supported surface and actual entry point. |
| Policy | Actor, action/grant, company/resource/ownership scope, responsible-user intersection, run requirements, work modes, and gates relevant to the operation. |
| Evidence | source-only, verified, failed, blocked, or not-run. Source presence and successful board calls are not agent verification. |
| Review depth | baseline records representative operations and known gaps; operation-reviewed enumerates the capability's meaningful operations and their individual access contracts. |
Broad capabilities such as task properties must be split into operations before they count as operation-reviewed: renaming, metadata edits, assignment, dependencies, and lifecycle changes can use different tools and permission rules. An available read path cannot certify a write path. List/get/create/update/delete, execution/control, credential handling, and resolution are separate where their authority or transport differs. Do not duplicate request schemas from OpenAPI.
Exceptions and restrictions
Presentation-only state, static developer fixtures, and pre-start/local operator
work may use not-applicable for a domain API, with a concrete reason and the
existing local path. When a capability combines shared data with presentation,
split the operations: browser recents do not exempt resource lookup from API
coverage. Promoting local state to a shared feature requires revisiting the entry.
A board-only endpoint is restricted for agent identity, not an automatic
exception or a missing API. Cite the enforced policy and record whether the
agent can request the authorized human's action and observe its result. An
unresolved delegation question remains in Gaps. Company access, a job title,
a personal assistant's OAuth grant, or an accepted interaction does not grant
board identity. Keep budget, approval, secret and execution authority intact.
Check actual route/service authorization and production tool admission. OpenAPI actor labels and scenario/evaluation tool declarations are supporting metadata; record disagreements rather than using them as proof of access. Native API fallback restrictions, tool field/scope limits, and rollout settings are part of the agent path, even when a legacy agent can call the REST endpoint directly.
Companion file format
Each agent-access-map/<area>.md has an H1, a relative link to its product file,
and its feature ID, followed by one H2 backticked local key per product
sub-feature. Each capability starts with its full capability ID and contains
these fields:
- Review:
baselineoroperation-reviewed. - API: presence state and exact operation IDs, or a reasoned exception.
- Agent access: availability state and concrete entry points by surface.
- Policy: relevant permission and runtime boundaries, with source references.
- Evidence: evidence state, reviewed commit and sources or executed proof.
- Verification: allowed/denied assertions and observable result; record what has actually run separately from the proposed recipe.
- Gaps: missing APIs/paths, discovery drift, unreviewed operations or policy
decisions; use
noneonly for the enumerated scope that was reviewed.
For an operation-reviewed capability, use H3 backticked operation IDs and repeat
API, Agent access, Policy, Evidence, Verification and Gaps for each operation.
Use small operation names such as create, update, read, or run-now.
The enclosing capability has Review: operation-reviewed only after its
meaningful operations have been enumerated. The following excerpt shows one
operation; include the others before using that review label:
## `definition`
Review: `operation-reviewed`.
### `create`
API: `present` — POST /api/companies/{companyId}/routines.
Agent access: `available` — agent REST, CLI routine create and native call_api
under the enabled rollout and active-run/mode gates.
Policy: same company; assigneeAgentId must be the calling agent; cite the
routine authorization and native API policy sources.
Evidence: `source-only` — reviewed commit and source links; no live proof.
Verification: `not-run` — create an owned routine; reject assignment to another
agent; inspect saved configuration, attribution and retry behavior.
Gaps: verify ownership and responsible-user resolution with a permitted agent
context; source presence alone does not qualify this operation.
Keeping the maps synchronized
When a change adds/removes a capability or changes its behavior, API, permission, tool binding, CLI support, or work mode, update the affected companion and product recipe as appropriate in the same change. Preserve IDs across renames where the capability is unchanged; update the affected cross-links together. Indexes discover recipes automatically. An API-only change may update the companion without rewriting unchanged user instructions. Update the corresponding chat scenarios when their request, assumptions or expected outcome changes; use multiple cases for meaningfully different starting conditions rather than treating an API path as conversational coverage.
maintain-verification-skill owns reconciliation of both maps. It follows changed source and authorization, checks real agent reachability, and records product gaps without implementing them during a maintenance pass. The creation skill uses this structure. verify-paperclip consumes the relevant recipes and reports evidence/drift; map editing belongs to maintenance.
Run the structural check after map changes:
node scripts/check-maps.mjs
It checks paired areas/IDs, navigation metadata, required fields, and local references. It does not certify endpoint authorization, production bindings, operation completeness, or live behavior. Source audits must check those against the existing API and tool contracts; avoid a second schema catalog or runtime.
For live access proof, use Paperclip's existing API/runner/MCP fixtures or an owned
isolated instance. Use the actual agent identity, target and work mode. Assert the
allowed result and relevant denial (another company/private resource, wrong
owner, missing grant, invalid run, restricted mode or resolver). Mutations also
need persisted state/attribution and retry behavior. Capture evidence using the
existing artifact workflow; keep executed run results
separate from generated maps/generated/coverage.json, which lists page references.
Local authorship and generated indexes
Change only the recipes, access contracts and stories whose behavior or intent
changed. Feature recipes own navigation metadata; stories own small
parameters.paperclip annotations. Keep the feature-map README's readable ID
index aligned with those sources; it does not register entries for generation.
Do not refresh counts in shared READMEs, inventories, fingerprints or review
journals.
node scripts/storybook-catalog.mjs validates and generates aggregate navigation,
Storybook data, verification routes and the page inventory. All outputs live in
ignored maps/generated/, ui/storybook/generated/, and the ignored Storybook
preview.tsx wrapper. Start/build and UI typechecking generate their own inputs.
A clean merged checkout therefore assembles both branches' changes automatically.
Git provides history and diffs. PRs, issues and CI artifacts retain review/run evidence for the named revision. Capability associations do not create whole-file review dependencies. Keep durable scenario limits in the affected recipe or story.
