fix(alerts): tell the owner when a proxied copy or its tunnel disappears - #62
Review mirror of GeiserX/CashPilot (same commits). Findings are carried to the upstream PR and fixed there.
Summary by CodeRabbit
New Features
The health dashboard now alerts when a proxied copy or its tunnel is missing or stopped, after a grace period. Alerts appear in the notification bell, link to the fleet page, and persist across restarts.
Status reports distinguish intentionally held copies from active ones.
Bug Fixes
Unreadable proxy status is no longer mistaken for an empty result, helping prevent misleading alerts.
Successfully removed workers have their proxied-copy records cleaned up when removal completes, without affecting the removal result if cleanup fails.
The container-down and missing-deployment checks read a status report that
leaves proxied copies and their tunnels out, so a copy or a shared tunnel
removed or dead outside CashPilot raised no alert. A new check compares the
proxied_copies records with each worker's proxied report, with the same
30-minute grace, dedupe and clearing as the container alerts. One alert per
tunnel names the copies that depend on it. Copies being removed, stopped by
the cap or the owner, or of a disabled account stay quiet, and a box that
cannot look (offline, blind, too old, or a failed read) neither raises nor
clears. The worker now says which copies are held, and sends None instead of
an empty list when it could not read them.
A service removed through the raw worker command route, or one whose removal
left some proxied copies behind (proxied_error), kept every proxied_copies
record of that slug on the box, so the new check paged the owner that copies
they had just removed were gone. Skip a copy whose service is no longer
deployed on its box, and drop the records on a raw remove as _svc_remove does.
…on the dashboard
A service deployed before per-box records has no placement row, so the new
removed-service guard silenced its proxied copies; the box still reporting
the service now counts as deployed there. The dashboard's attention list
never listed proxied copies, so it said nothing needed the owner while a
copy was down; the alert is now a card there. A raw remove that cannot drop
the copy records no longer reports a removal that happened as failed.

Walkthrough
The health check now evaluates proxied-copy and tunnel status reported by workers. It records and restores alerts, clears resolved alerts when status can be judged, and displays proxied alerts in the dashboard. Successful worker removal also cleans up proxied-copy records unless the worker reports an error.

Layer / File(s)
Summary
Report proxied-copy status app/proxy_tunnel.py, app/worker_api.py, tests/test_proxy_shared_tunnel.py
Worker status entries include held-copy information when readable. A failed tunnel-status read raises ProxyTunnelError at the status source and is reported as null in the heartbeat rather than as an empty result.
Evaluate and retain health alerts app/main.py, tests/test_proxied_copy_alert.py
The health check evaluates eligible worker reports against recorded copies and deployment state. It applies exclusions and a 30-minute grace period, then records, restores, or clears alerts.
The attention panel and notification bell identify proxied-copy alerts. The notification suppresses credential-fix actions for these alerts.
Clean up records after worker removal app/main.py, tests/test_main_deploy_routes.py
Successful worker removal deletes proxied-copy records unless the worker reports a proxied-removal error. Database cleanup failures do not change the successful response.
geiresx/CashPilot#11: Changes proxy-copy cap-stop behavior, which this pull request accounts for when evaluating alerts.
geiresx/CashPilot#55: Adds shared-tunnel and held-copy reporting used by the new health checks.
geiresx/CashPilot#50: Tracks unconfirmed removals, which this pull request excludes from missing-copy alerts.
Merge Risk: Low · previous review 7fb17
Owners of older proxied copies without placement records may lose a stored alert while the worker cannot report, then be notified again later. This is a narrow edge case, so it is mergeable with owner awareness or a small follow-up.
Security architecture risk: Moderate · up to 7fb17
Removal cleanup can erase the ownership record of a copy whose deployment is still in flight, leaving a running copy outside record-based traffic accounting and removal safeguards. This requires overlapping authenticated operations and is limited to the selected worker and service; no new anonymous access or privilege escalation was identified.
Retained concerns
Medium · security · inferred: The new worker-command removal cleanup can delete ownership records belonging to an in-flight copy deployment. Copy creation can pass the deployment prerequisite and save its record before removal, then reach the worker after remove_all finishes. The subsequent worker-and-service-wide deletion erases that record, while successful copy deployment does not restore it. This can leave a live, credential-bearing copy excluded from record-based accounting and allow proxy deletion without removing it. The analogous canonical removal path predates this PR; the regression is its extension to the raw command route.
Security review details
Security Blast Radius
inferred — The ownership race requires an owner-authorized copy deployment overlapping a writer-authorized removal. Cleanup affects all proxy-copy rows for the selected worker and service, not the entire fleet. A surviving copy can retain its service settings and tunnel credentials after its controller record disappears.
Security Findings and Attack Paths
inferred — The material consequence is loss of lifecycle control, not an authentication bypass: an erased row excludes the copy from uncapped traffic accounting and removes the proxy-deletion guard's evidence of that live copy. The same cleanup pattern existed in the canonical removal route, but the raw command route did not previously erase these rows.
Trust Boundaries and Controls
observed — Heartbeat authentication precedes worker-state upsert, alert reads use the existing authenticated endpoint, and the changed dashboard paths escape alert text and names before HTML insertion. These controls constrain report ingestion and presentation but do not make worker self-reported status independently trustworthy.
Resilience and Maintainability Implications
observed — Removal preserves copy records when the worker reports proxied_error, and cleanup exceptions do not reverse the already-completed removal response. An already-capped proxy also targets running heartbeat-reported copies even without records. These recovery controls mitigate partial removal and existing caps, but do not restore a concurrently erased ownership row.
Hardening Proposals
proposed — Coordinate service removal and copy creation through a shared worker-and-service lifecycle guard or generation. Preserve ownership until in-flight remote operations are reconciled, so successful removal cannot silently erase a newer deployment's record.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Fragile string replacement on the shared _HARNESS.
The second replace (Lines 356-358) has no assert harness != ... check. The first test on Line 329 does assert this. If the _HARNESS text in tests.test_account_disabled changes, the replacement silently does nothing. The test then fails later with an unclear Node error, such as refreshAttentionOnAlertChange not being returned or bell not being defined. Add an assertion after each replace, as the first test does.

- Around line 1734-1737: Update the alert redraw flow around
`_attentionAlertsKey` and `renderAttention` so a failed redraw does not mark the
alert as handled: reuse the already-fetched alerts when supported, or advance
the key only after a successful redraw. Preserve retries on later polls for the
same alert when rendering fails.
