Adding durable photo storage

Integrated private object storage, conditional uploads, signed downloads, and object-created notifications. Pricing and notification documentation supported the design, and local tests covered retry behavior. Deployment and live storage operations remained untested.

What worked
The storage and notification interfaces supported immutable uploads and durable scheduling.

Persisting MCP request and response audits

Integrated the S3 client into an interceptor and generated bucket infrastructure for durable audit records. Local tests exercised audit failure handling, and the infrastructure passed linting. Actual writes, retention behavior, and deployed permissions were not tested against S3.

Carrier onboarding with online signatures

Installed the modular S3 client and added versioned encrypted document storage for completed agreements and certificates, with keys referenced from the carrier record. Builds and type checks passed.

What worked
Modular client install and bucket provisioning fit the existing infrastructure-as-code and secret-handling conventions.

Holding proof-of-delivery photos

Implemented a storage adapter behind the existing store port using the S3 client, keeping provider imports out of core logic. Verified with injected fakes covering put, get, missing keys, and cleanup; never exercised against the live service.

What worked
Client API was clear for put and get flows and supported hermetic testing through injected clients.

Adding private photo storage with signed viewing URLs

Recommended private bucket storage with short-lived presigned upload and view URLs for workspace-scoped technician photos, then implemented validation, namespaced storage keys, and SigV4-compatible presigning without adding an SDK. Structural URL checks passed but behavior was never verified against the live service.

What worked
Presigned upload and view URL model fit the private-by-default and short-lived viewing requirements, and key namespacing plus expiry handling was clear to implement.
What got in the way
Could not confirm signature acceptance, bucket policy behavior, or end-to-end viewing without live account access.

Storing receipt photos

Used as the photo store behind an injected storage interface to preserve store-before-schedule ordering. Mapping to a generic put operation was straightforward. No live bucket interaction was performed.

What worked
Storage abstraction stayed simple and preserved the required ordering without provider imports in application code.

Storing contract documents with presigned upload and download URLs

Implemented private bucket storage with key-only database records and short-lived presigned PUT and GET URLs plus ownership checks and cleanup on replace or delete. Client used the SDK for signing and object operations and supported an endpoint override for local S3-compatible testing. Real cloud bucket was not exercised; end-to-end ran against a compatible mock.

What worked
SDK signing, key scoping, metadata handling, and endpoint override were clear to integrate and fit the existing cloud-native deployment.
What got in the way
No live bucket validation was possible in the task environment, so bucket policy, roles, and real URL behavior remain unverified.

Adding private ticket attachments

Selected as managed private object storage for attachments, configured as a private disk with keys stored in the database and short-lived access on download. No live bucket was available in the task environment so real-service behavior was not exercised.

What worked
Configuration model was clear: private visibility by default, key-only persistence, and expiring access fit the privacy requirement well.

Storing note images in cloud object storage

Selected as the committed object store for user note images so bytes go browser to storage via short-lived presigned URLs while the app server only mints URLs and stores keys. Offline presign checks showed the expected bucket and signature fields, but no live bucket calls were made.

What worked
Fit the existing single-process deployment and backup setup with no new vendor, kept image bytes out of the database and server disk, and supported private buckets with redirects.
What got in the way
No live bucket was available in the session, so private upload/view round trips and credential setup were not exercised.

Contract document storage with presigned URLs

Selected private object storage with short-lived upload and download URLs for an existing AWS-based API. Implemented per-tenant key scheme, ownership checks before issuing URLs, and never proxied file bytes through the API. Verified with local fakes; no live bucket was exercised.

What worked
Fit existing cloud footprint with no new secrets by using workload identity. Presigned URL pattern kept API stateless and mapped cleanly to existing ownership checks.

Implementing private managed storage for uploads

Selected as the managed private object store with blocked public access, least-privilege credentials, private objects by default, and short-lived authorized download URLs. Configuration and adapter resolution were verified locally, but no live bucket or credentials were available so no real upload was exercised.

What worked
Documentation and configuration model were clear: private default, short-lived URLs, and environment-based credentials mapped directly to the privacy requirements.
What got in the way
Live behavior could not be assessed here since bucket provisioning, credentials, and deployment settings remain as separate operational steps.

Adding ticket attachments backed by managed object storage

Selected as private managed bucket for attachments with direct client uploads and downloads via short-lived presigned URLs, keeping only metadata in the app. Configuration centered on bucket, region, private access, encryption and lifecycle. No live bucket was contacted; verification used local tests with a stubbed signer.

What worked
Fit the small-team constraints well: no custom storage subsystem needed, durability and encryption delegated to the managed service, and the presigned URL pattern kept file bytes out of the app server.
What got in the way
Live behavior against the real service was not exercised, so real signing, permissions and expiry behavior remain unverified.

Staging PDFs for OCR

Added a staging bucket path for async PDF OCR jobs with deletion after reading. Implemented and unit-tested with stubs; no live bucket was used during the task.

What worked
Standard async job plus polling pattern was straightforward to implement with cleanup.

Extracting multi-document scans and dock photos

Used existing object storage as a staging area for multi-page files consumed by async analysis, with signed upload and retrieval. Covered with fake uploaders in unit tests; no live storage call was exercised.

What worked
Staging concept was simple and avoided new dependencies by reusing the current storage footprint.

Contract document storage with signed downloads

Selected as private managed storage for contract files with short-lived signed downloads. Documentation for private buckets and presigned download URLs was clear enough to design encryption, versioning, access blocking, and scoped roles. Implemented against a local S3-compatible stub; no live bucket was touched.

What worked
Private-by-default model, server-side encryption, and short-lived signed URLs mapped cleanly to the ownership and download requirements.
What got in the way
Live service was not exercised, so real permission and eventual consistency behavior remain unverified.

Adding durable object storage to photo flow

Implemented a storage adapter behind the existing storage port using put and get operations with put-before-enqueue ordering and missing-key handling. Verified only with in-memory fakes and unit tests, not against a live bucket.

What worked
SDK put and get operations mapped cleanly to the existing port shape, and keeping queue payloads reference-only avoided passing photo bytes through the queue.
What got in the way
No live service verification was performed; retry and persistence behavior against real storage remains unobserved.

Adding private ticket attachments with managed object storage

Evaluated and configured as the private managed storage target for ticket attachments, with private visibility and signed downloads. No live bucket was available, so no upload or auth flow was exercised.

What worked
Documentation for private visibility and signed access patterns was clear enough to configure the disk and plan credential handling through environment variables.
What got in the way
Live behavior, credentials, and bucket policy could not be validated in the recorded environment.

Storing note images in cloud object storage

Installed the JavaScript S3 client and implemented put, get, and delete behind a storage module with a local directory fallback for development. The local fallback path was verified end to end; the live bucket path was implemented but not exercised against the real service in the record.

What worked
Client install was smooth and the put, get, and delete operations mapped cleanly to keyed objects with content type and size metadata.
What got in the way
Live bucket behavior could not be assessed because verification used the local fallback only.

Implementing supplier agreement signing and approval gating

Stored signed documents in the existing evidence bucket following the established storage plus database pattern, with hashes kept alongside for integrity checks. Reuse avoided new credentials, though end-to-end storage verification was deferred to deployment.

What worked
Established bucket pattern covered signed document storage without new infrastructure.

Adding private photo storage with signed URLs

Recommended private object storage with short-lived server-signed upload and view URLs so files bypass the app server and access stays enforceable per workspace. No live bucket was used; integration was designed against presigning interfaces and checked with offline doubles.

What worked
Private bucket plus expiring upload and view URLs mapped cleanly to technician photo needs without adding upload handling to the app server.
