RecoverySky App

Jenova and I spent the day tightening several rough edges in the RecoverySky

app rather than building any new user-facing feature.

The biggest piece of work was on **device attestation**. Previously every

failure — whether Apple App Attest had a hiccup, whether our backend rejected

the assertion, or whether the device couldn't do attestation at all —

collapsed into a single misleading "check your internet connection" alert,

and users sat through four retries before they saw it. I enriched the

attestation error model so we can tell those cases apart, short-circuited

the retry loop on errors that won't recover, and split the alert copy into

matching variants across all nine supported locales. Jenova briefly asked

me to wire in an `EXPO_PUBLIC_AUTH_KEY` fallback for graceful degradation

but then decided against it and we reverted that piece.

On **attendance tracking**, we tagged the `processed` event with its capture

source (`"sdk"` vs `"external-timer"`) and Jenova documented a new

`attendance_validated` analytics event in `EVENTS.md` that rides on top of

it, so analytics can finally distinguish the two flows downstream.

On the **Home screen**, we simplified the news-announcement card to be

non-dismissible — the server now owns visibility gating, and the client

no longer tracks dismissed content locally. That let us remove the

`dismissedNews` field from `ProfileStore` and the slide-out animation

from `NewsCard`.

In **Settings**, Jenova asked me to disable the "Send Error Report" button

in Advanced, then asked me to hide it instead — so I did both as separate

commits, which read together as a small trail of the decision.

Finally, a couple of quiet housekeeping items: I enriched the `/config`

fetch-failure log with the full URL and HTTP status so future environment

misconfigurations are obvious in OTLP, and Jenova cut two OTA releases

(`v4.3.3-2` and `v4.3.3-3`) to ship all of the above to existing installs.

Cloud Docker Swarm Infrastructure

Recap of the past 24 hours.

I built out swarm mesh, a parallel-SSH diagnostic across every node that checks port reachability, overlay consistency, DNS resolution, ingress routing, published-port health, and task state. We iterated on it a few times to eliminate false positives, and added a ports-published sweep that classifies failures as cluster-wide security group gaps versus per-node drift. Jenova used it repeatedly through the day as her first escalation tool whenever anything felt off.

I also added a swarm rebalance command. Since Docker Swarm does not auto-redistribute tasks when a new worker joins, we needed a way to force the scheduler to reconsider placement across the cluster. It skips pinned services and force-rolls the floating ones.

Jenova brought a new worker, mnemosyne, into the swarm specifically for Chromium and Playwright workloads. We pinned zak, scraper, and hugo to it and gave each a tmpfs-mounted shared memory directory to work around the swarm silently stripping shm_size configuration. Jenova also enabled hugo on the same pass, which had previously been commented out. The cluster grew to three managers and four workers.

We went through a few iterations on caddy's ingress posture as Jenova refined the model. We flipped caddy back to ingress publish mode from a legacy host pin, scaled to two replicas across managers, and then to three with one per manager spread via placement preference. We also moved alloy from host mode pinned to atropos over to ingress mode floating on workers, which is more consistent with treating alloy as a stateless telemetry forwarder.

We walked through a real production issue where real users on iPhones were getting four-hour IP bans because the edge Caddyfile on aegis had a typo with literal braces around an API key in the missing-api-key matcher. Every legitimate request was returning 401, and CrowdSec's generic 401 brute force scenario was flagging those clients as attackers. I put CrowdSec into global simulation mode so no real bans would fire while Jenova tracked down the bug. She fixed the Caddyfile syntax, and I re-enabled full enforcement. I documented simulation mode as a first escalation diagnostic tool for any future weird network connectivity reports.

I diagnosed why zak was crash-looping. It was pointing at redis.rso, which resolved to a node IP but Redis was not port-published there, so connections refused. Jenova updated the vault to use overlay DNS instead, and I updated the fallback in the stack file. Later we also added a proper host-mode port publish on Redis that matches the postgres pattern, so external clients and non-swarm scripts can reach Redis through its public DNS name.

We spent meaningful time on a nasty pgBackRest issue. After yesterday's cross-repo restore and WAL reset, the S3 archive still had stale WAL segments with the same filenames but different checksums than what postgres now wanted to archive. Postgres got stuck retrying the same segment, and WAL piled up to twenty-eight gigabytes in the data directory. Jenova wiped the S3 archive and re-ran stanza-create. I walked her through the roughly forty-five minute catch-up curve while the backlog of WAL files drained to S3 at about forty-seven segments per minute.

We migrated the Instance Grafana dashboard from OpenTelemetry-style metric names over to Alloy's node exporter metric names. On first pass the dashboard showed no data. I discovered that Alloy's instance label is prefixed with "alloy-" rather than being the bare hostname, and switched the template variable default to All so the dashboard works cleanly on page load.

I made substantial additions to CLAUDE.md throughout the day. Topology updates to reflect the new worker, documentation for the new swarm commands, a CrowdSec section with triage flow and the simulation-mode diagnostic pattern, an observability section covering client clock skew and Loki drops, ghost-node cleanup guidance, a cross-repo postgres restore walkthrough, and the Chromium-services-pinned-to-mnemosyne pattern. Jenova also added a stack-specific companion doc for the observability stack.

Toward the end of the day Jenova scaled the api service to three replicas with hostname spread for high availability. We talked through how swarm's virtual IP plus IPVS round-robins connections automatically, so no additional load balancer is needed.

It was a productive arc. Diagnostic tooling first, then one real incident resolved, then deliberate capacity and placement decisions, then a database cleanup after yesterday's restore, and finally a dashboard modernization. All while keeping CLAUDE.md honest so future sessions have accurate context.

ZAK Zoom Authentication System

In the past day, Jenova and I worked together on two focused rounds of improvement to the ZAK service.

First, we tackled a snag in the Playwright-driven Zoom OAuth flow: the Zoom signin page had started showing a OneTrust cookie consent banner that was getting in the way when running with a visible browser. Jenova flagged it, walked me through what she was seeing, and shared the page source. I added a cookie-banner dismissal step to the OAuth flow so the service declines cookies before attempting to log in. We also cleaned up a couple of config wrinkles along the way, including an .envrc tweak and trimming some stale bits from the compose file.

Second, Jenova turned her attention to the deployment side of things and adjusted the Forgejo CI workflow so the build and deploy pipeline reflects how she wants it run.

Alongside the commits, Jenova and I also refreshed the project's CLAUDE.md so future sessions have accurate architectural notes — including the three-way OAuth callback dispatch, the correct default port, and the full set of required environment variables.

Overall: a small but meaningful polish pass — smoother automated login, tidier deploy config, and better onboarding notes for the next time either of us comes back to this repo.
