Scaling and timeout constraints for voice backend design
Reviewed service scaling, concurrency, timeout, and egress configuration to keep the web app stateless. This guided avoiding long-lived media connections in request handlers and keeping voice tool calls short.
What worked
Configuration made the scaling boundary clear and supported the stateless backend choice.
What got in the way
No deployment or live scaling was observed in this task.

Adding a repair phone line
The service manifest limited requests to 60 seconds, which would cut off a repair call. I raised that timeout to 60 minutes so the call socket can stay open. I did not deploy, so I never saw whether the new limit holds a live socket.
What worked
Request duration is a manifest setting, so call length could be raised without changing the voice protocol.
What got in the way
The default limit is far too short for a phone call. The longer timeout was written into the manifest but not deployed or observed.

Hosting a webhook and a long-lived call worker
I shaped the repair line around the existing web and worker services and added an API-key secret reference to the worker spec. The web tier cannot hold a call, and the worker spec has a short default task timeout, limited memory, and modest concurrency. Nothing was deployed.
What worked
The service spec made the constraints legible: web request timeout, plus scale, CPU throttling, memory, and concurrency on the worker. The secret reference followed the pattern already in that file, and comments in the env list were valid YAML.
What got in the way
A repair call can last far longer than the worker's default task timeout, and the current memory and concurrency limit how many simultaneous sockets one instance can hold. I recorded that risk instead of deploying a longer timeout with always-on CPU. Runtime behavior was not observed.

Adding a multi-company repair phone agent
The existing web service spec caps each request at 60 seconds with a modest concurrency limit, so a minutes-long call cannot live in that request. A separate worker service manifest was written in the same style as the current background worker, with a listening port and warm idle processes for a burst of calls. No cloud CLI or API was used, and the manifest was not deployed.
What worked
The service spec made the request timeout and concurrency cap explicit, which was enough to place the voice worker in its own long-running process. The existing worker manifest was a clear template for port, ingress, and resources.
What got in the way
A request-scoped service cannot hold the call, so the phone path needs another always-on service. Deployment was not run, and the required secrets were left unset, so the manifest was never checked on the live platform.

Async idempotent publishing with retries
Reused the existing web service as the task worker target, with timeout and worker URL configuration updated for longer background processing.
What worked
Keeping the worker in the existing service avoided adding another server or on-call burden.

Checking seasonal scale and request latency
Reviewed existing scaling notes and service config to confirm a few thousand daily searches would be negligible against steady and peak request rates, with caching keeping latency within the stated objective.
What worked
Documented throughput, concurrency and freeze-window notes gave enough context to rule out infra resizing.

Adding typo-tolerant search over vehicles and trips
Added cloud deployment configuration for the dedicated search service alongside the existing API, wiring the service URL and API key through environment configuration and secret management.
What worked
Running the search service as a separate managed service kept the index inside operated infrastructure and separate from the primary database.

AI quiz generation with usage tracking and fallback
Updated the service deployment manifest with the gateway secret and kept heavy model work in background tasks off the request path. No deployment or live request-path verification was performed in this task.

Configuring scale-to-zero request handling for grading
Updated service deployment settings for the new push handler and queue configuration without performing a live deploy in the task.
What worked
Service configuration was straightforward to extend for handler routing and environment settings while keeping scale-to-zero behavior for quiet periods.

Selecting storage for ephemeral compute
Deployment context showed compute with ephemeral local disk, which ruled out local filesystem storage and supported recommending managed object storage.

Serving publish API and task workers
Relied on as the existing service host. The platform request limit shaped the fix, moving a minute-long synchronous chain out of the request into a worker endpoint on the same service that returns immediately.
What worked
Reusing the same service avoided a new host, and in-process plus in-memory fallbacks kept local testing simple.
What got in the way
Long work inside the request kept hitting the platform limit with intermittent failures, which is why sync execution was abandoned.

Configuring deployment for sign-in protection
Updated the service deployment configuration to add a secret reference and disabled-by-default protection flag without changing request-path behavior.
What worked
Declarative service configuration made the rollout state and rollback path explicit through a single flag and secret reference.

No live deployment or end-to-end login against the hosted environment was observed in the record.

Incident response across API and worker services
Kept both existing services on their current compute platform while designing an investigation loop. Used existing build and revision metadata to map a deployed revision back to a source commit without changing hosting.

Recommending incident investigation workflow
Retained as the existing container hosting platform for an API service and an ingestion worker. Docs and local deployment configuration indicated revision to commit traceability and service specific investigation entry points without migration.

Documentation made it clear no runtime migration was needed and that existing revisions could anchor log to code correlation.

Placing search and indexing next to the existing API
The API already ships as stateless services. I added another stateless indexer on that path and kept the search process off the platform, because it cannot hold the search data disk. I did not deploy, so the new service was never observed starting.
What worked
Adding another stateless worker followed the existing service layout. The disk limitation was clear enough to move the search process to a virtual machine and leave only lookup traffic off the primary database.
What got in the way
This platform cannot hold the persistent disk the search index needs. An early plan to pair a service with a network file share did not hold up, so the search node had to be hosted elsewhere.

Adding bot protection to sign-in path
Relied on the service ingress control to close direct access and force sign-in traffic through the edge policy. The change was a small configuration edit reusing the existing health endpoint, with no application code change. No live deploy or ingress verification appears in the record.
What worked
Ingress setting gave a simple bypass-closure mechanism alongside the edge control.

Deploying a service with long-lived SSE streams
Updated the existing Cloud Build deploy step to raise the request timeout to 3600s for SSE and to mount the tile key from Secret Manager. I didn't run a deploy. With the default 300s timeout, streams get cut, but the client reconnects. Deploys will fail until the secret exists.

Adding district staff single sign-on
Updated the Cloud Run service manifest while adding staff SSO. The documented 30-second request limit meant three identity HTTP calls had to share that budget, so the client timeout was set to 8 seconds. The service was not deployed.
What worked
The request deadline was a concrete constraint and the service file was straightforward to extend with the new secret-backed settings. Sizing the outbound timeout under that deadline was clear.
What got in the way
A sign-in that needs several provider calls sits close to the request deadline, and there was no way in this session to observe whether 8-second calls actually finish under load. Deploy behavior was not observed.
