The dry run matters because the lookup by head SHA ("direct match") is the normal path since 2026-11-13.

Tags are never re-pushed. Two cautions once immutable releases are on: - Never re-run a release run whose tagged commit predates WP2 (issue #295): a re-run uses the `release.yml` of the tagged commit, and the old file publishes a pre-release before its APK is uploaded, which would lock the tag without the APK. Only runs of tags made after WP2 are re-runnable. +- Re-running after a failed `sign` job needs no such check (nothing was published); see "Release signing" below. - Before re-running a failed `publish` job, look at what exists for the tag: `gh api repos/hellwand/nova/releases --jq '.[] | select(.tag_name=="") | {id,draft,immutable,assets:[.assets[].name]}'`. If a published release is listed, do not re-run and do not delete it (`gh` can report an error after the server already published, and a deleted immutable release burns the tag name for good). Delete a leftover draft (`gh api -X DELETE repos/hellwand/nova/releases/`) before re-running; a draft is left behind when the job is killed during the upload. +### Release signing + +The release key is used in exactly one place: the job `sign` of `release.yml`, which declares `environment: release`. That environment holds the secrets `KEYSTORE_B64`, `KEYSTORE_PASSWORD`, `KEY_ALIAS` and `KEY_PASSWORD`, and its deployment policy accepts only tags matching `v*`. GitHub refuses a job that names the environment on any other ref (a pull request, a branch) with "not allowed to deploy to release due to environment protection rules", so pull request code cannot reach the key. The job signs the APK that the pull request's CI built (debug-signed, no secret involved) with `apksigner`, v2 only, then checks the alignment, compares the entry list and CRC-32 values of the downloaded and the signed APK (signature files excluded; any difference fails the job), runs `release-verify-apk.sh` (pinned certificate, exactly one signer) and deletes the keystore file. Only then can `publish` run. See [ADR-0004](docs/adr/0004-build-once-promote-pipeline.md), amendment 2026-11-13. + +- **What a contributor's pull request builds:** the same minified release APKs as before (both flavors), signed with the Gradle debug fallback. The step "Confirm there is no signing key" in `build-release` prints `Release build runs WITHOUT the keystore` and fails the job if a keystore or signing variable is present at the start of the job; the step "Confirm the release APKs are not release-signed" after the build fails it if either APK carries the pinned release certificate (digest read from `release-verify-apk.sh`). Whether the release key works is first proven by the tag run. +- **What the release run does:** `guard` → `sign` → `publish`. The Actions UI shows a deployment to `release` for the `sign` job. +- **If `sign` fails** (typically `KEYSTORE_B64 is empty`, "keystore password was incorrect" or a wrong alias): fix the secret in the environment (`gh secret set KEYSTORE_B64 --env release < keystore.b64`, and likewise the other three; read back the names with `gh secret list --env release`), then `gh run rerun `. The tag is not moved, no new version is needed, and nothing was published. A failure of the entry comparison or of the pinned-signer check is not a secret problem: do not retry blindly, find out what changed between the CI artifact and the signed file. A bug in the workflow or script itself uses up that version (ADR-0015); fix forward. +- **One-time step after the first good tag run** (the `sign` job green and the release published): delete the repository-level copies of the four secrets, so that the environment is the only place that has them: `gh secret delete KEYSTORE_B64 --repo hellwand/nova` and likewise `KEYSTORE_PASSWORD`, `KEY_ALIAS`, `KEY_PASSWORD`. Then `gh api repos/hellwand/nova/actions/secrets --jq '[.secrets[].name]'` must print `[]`, and the next pull request's CI is still green (it never used them). Until then the repository secrets exist but no workflow references them (a job with `environment: release` reads the environment's values first). + ### Release cleanup `gh release delete --yes` — never `--cleanup-tag`.

The job decodes the keystore into the runner's temp directory, runs `apksigner sign` (`.github/scripts/release-sign.sh`: v2 on; v1, v3, v4 off, like every published APK so far), checks `zipalign -c -P 16 -v 4`, compares the entry list with CRC-32 values of the downloaded and the signed APK (signature files excluded; any difference fails), runs `release-verify-apk.sh` unchanged (pinned certificate, exactly one signer, so a surviving debug signature fails closed), deletes the keystore, and hands the signed APK to `publish` as an artifact of the same run. `publish` uses that APK and the mapping from the CI run. +- **"Bit-for-bit" becomes "entry for entry".** What is promoted is the same compiled code and resources that the pull request built and tested, entry for entry (the comparison above proves it on every release); the signature is added at promotion. The released file is not byte-identical to the CI artifact, and nothing needs it to be: the in-app updater checks the published asset's digest, and immutable releases freeze that digest. +- **Costs.** Pull request CI no longer proves that the release key works; a broken environment secret fails the tag run before anything is published, and is fixed by correcting the secret and re-running the run (`gh run rerun`), with no new tag. A release takes about a minute longer. A bug in the sign job uses up that version (fix forward, ADR-0015). +- **Residual.** Who may push a `v*` tag stays a convention (R-RELEASE); the environment has no required reviewer, because every tag is the maintainer's decision and all guards run before signing. + ## Alternatives considered - **Build on tag push** (the naive approach) — slower and introduces drift. diff --git a/docs/adr/0014-single-ci-run-per-pr.md b/docs/adr/0014-single-ci-run-per-pr.md index 8b3edef2..6e1390f2 100644 --- a/docs/adr/0014-single-ci-run-per-pr.md +++ b/docs/adr/0014-single-ci-run-per-pr.md @@ -99,3 +99,9 @@ The squash-era wording in `release.yml` and `release-guard.sh` is reworded; the - **Preflight at the tag.** The guard calls `.github/scripts/release-preflight.sh`, the script the pull request job `release-check` also runs: version shape (ADR-0005), `versionCode` above the previous `v*` tag, tag name free or already on this commit, and a non-empty `CHANGELOG.md` section (ADR-0031).

Such an APK is signed with the debug key and is not installable as an update of a released NOVA. Bot heads are still never tagged (ADR-0015 needs a release commit of its own), and even a tagged one could not ship: the guard requires a green `pull_request` run on the tagged commit and the version checks, and `release-verify-apk.sh` rejects any signer other than the pinned release certificate.

The server compares actions exactly: `UPDATE_ANY` does not imply `READ_ANY`, and `*_OWN` never satisfies an `*_ANY` check. +- `me` is non-null: a `FORBIDDEN` on it nulls the whole response, so it must not share a request with the version. +- A wrong key gets `UNAUTHENTICATED` with HTTP 200 on every query except `__typename`, which is what the existing `Ping` sends. An unknown field gets HTTP 400 with `GRAPHQL_VALIDATION_FAILED`. +- Introspection is blocked on a stock 7.4.0 server (sandbox off), so the schema cannot be asked what it supports. + +## Decision + +Detect two things per server, with two small queries, keep the result in memory, and make it available as state. This change adds the foundation only; no screen reads it yet. + +- **Model** (`data/model/ServerCapabilities.kt`, pure Kotlin): `ServerCapabilities` holds the API version (parsed; a build suffix is ignored when comparing), the key's roles and explicit grants, and a `Detection` state. `access(KeyAction)` answers `Allowed`, `Denied` or `Unknown` from the static role table plus the explicit grants; `supports(ApiFeature)` answers `Yes`, `No` or `Unknown` against the floors 4.30.0, 4.35.0 and 4.36.0. `KeyAction` is the single list of controls NOVA offers and the permission the server checks for each; a unit test requires that every mutation in `mutations.graphql` belongs to exactly one, so a new control cannot slip past hiding or the documentation. +- **Detection** (`GetApiVersion`, `GetKeyAccess` in `queries.graphql`): two operations on purpose, so a refused `me` does not lose the version. `CapabilityProbe.kt` sends them and classifies the answers by `extensions.code`: `UNAUTHENTICATED` is a rejected key, `GRAPHQL_VALIDATION_FAILED` on the version means an API older than 4.15.0, `FORBIDDEN` leaves the access unknown, transport and other errors are a failed detection. The mapping lives in its own file, not in `GraphQlMapper.kt`. +- **Wiring** (`CapabilityRepository`, a singleton built like `UpdateTracker`; `MainViewModel.capabilities`): detection runs when the target (server id, resolved address, API key) changes, on pull-to-refresh, and when the app returns to the foreground. There is no timer, no retry loop and no polling, so nothing runs in the background. +- **Fail open.** Unknown is never denied. A detection that fails, a `me` that is refused and a role NOVA does not know all leave the access `Unknown`; a later UI shows controls unless the access is `Denied`, which only a successful detection can say. A failed re-detection keeps the last good result for the same target; a new target starts unknown, so one server's result never gates another. +- **Memory only.** Not stored in DataStore or in `Server`: a server upgrade or a changed key would leave a stored result stale. + +Domain availability (is Docker or the VM service turned on, does the server have an array) is deliberately not part of this model. It would cost more queries, goes stale when the user switches a service on, and each tab's own query answers it on every poll anyway. + +## Consequences + +- **Positive** — one place that knows the API version and the key's access; later changes (hiding controls a key cannot use, the atomic container restart, the Add server test, per-tab error reasons) read it instead of each probing the server. No visible change in this step. +- **Negative / trade-offs** — two more small requests per server change, pull-to-refresh and return to the foreground. The static role table copies the server's policy and can drift; an unknown role fails open, so drift can only show a button the server then refuses, never hide one the key may use (exception: a role that loses rights it has today). The CONNECT role is mirrored from the upstream policy but NOVA's detection of it is unverified on a live server. +- **Deviation from the first design, on purpose.** The detection pipeline lives in the application scope for as long as the repository exists, instead of being shared only while a screen collects it. The return to the foreground arrives together with the screen's own re-subscription, so a refresh that depended on an active collector could be lost. The foreground refresh fires on every start of the main screen; it joins a detection that is already running, so the first start does not probe twice. +- **Trigger to revisit** — if the Unraid API exposes a supported way to ask for the key's effective permissions without `PERMISSION:READ_ANY`, replace the static role table; if the role policy changes upstream, update the table and the test that pins it; if a feature must be gated that has no version floor, revisit the "no introspection" rule once introspection is allowed by default. + +## Alternatives considered + +- **Introspection of the schema.** Would tell exactly what the server has, but a stock Unraid 7.4.0 blocks it unless the developer sandbox is on, and 4.37.8 and newer also block `__type`.

Until now NOVA did no background work at all. ADR-0017 states it as a rule: the app lifecycle gates every poll, "so backgrounded app = zero polls, period". (Release 0.1.42 did not remove background polling; it fixed three screens that kept polling while the app was in the background, which is the same rule.) + +The maintainer decided on 2026-11-13: alerts are opt-in and off by default, and background checks exist only while the switch is on. The default level is alerts and warnings. + +The facts the design rests on: + +- Unraid's own monitor already creates a notification, with an importance of alert, warning or normal, for hot disks, SMART warnings, disks in error, full disks, read errors, a degraded pool, a boot drive that is not writable and parity checks. NOVA already reads the unread alerts and warnings with the query behind the bell (`GetNotifications`). +- Unraid does not notify about an array that is not started, and it stays silent about disk errors while the array is stopped. +- Unraid's notification agents send plain HTTP posts. UnifiedPush requires encrypted messages from the sender (RFC 8291), so it cannot be fed by those agents. +- The API key is stored encrypted with a key in the Android Keystore that does not require an unlocked device or user authentication, so a background check can use it. + +## Decision + +**Add an optional background check for alerts that runs only while the user has switched it on.** With the switch off, NOVA still does nothing in the background, exactly as before. ADR-0017's rule stays in force for every screen stream; only this opt-in job is an exception to it. + +What is decided here, and what this first change implements: + +1. **Events.** A new unread Unraid notification of importance alert or warning, and two array conditions that Unraid never notifies about: the array is not started, and the array is degraded. The array conditions are the rules of `attentionItems` (the Overview card), wrapped and limited to those two keys; nothing is forked. Disk temperature, disk errors, parity and pools are not raised from the array data again, because Unraid already sends them as notifications and every problem would be posted twice. Information-level notifications are never alerts. Containers and an unreachable server are not alerts either: a stopped container is often deliberate, and the phone cannot tell "server down" from "phone away from home". +2. **Once per notification.** Each server remembers the ids of the notifications it has seen. An id is never posted twice, even if the notification leaves the unread list and returns. The id is built from the event time, so a later notification with the same text is a new event and is posted. The list is kept in insertion order and capped at 300; an id that is still on the server is never forgotten before one that is gone, so the stored state cannot grow without bound. +3. **First check is silent.** The first successful read of a server after the switch is turned on, or after the server is added, only records what is already there and posts nothing. Turning the switch off forgets all state, so the next start is a first check again. The same rule applies to the array conditions. +4. **Array conditions once per episode.** A condition is raised when it begins and again only after it was gone at an in-between check. +5. **Level.** "Alerts and warnings" posts everything above; "Alerts only" leaves out new warning notifications. The two array conditions are always posted, because Unraid never notifies about them. Notifications the level filters out are still remembered, so widening the level later does not post old ones. +6. **Failures change nothing.** A check that did not load a half (server unreachable, certificate problem, key missing, request rejected) neither posts nor alters the remembered state of that half, so alerts created during an outage are posted once when the server answers again and nothing is posted twice. A failed check never counts as the silent first check. +7. **Several servers.** Every saved server has its own state, keyed by its stable id, and the state is removed with the server entry. +8. **At most five alerts per server and check** get their own notification, most urgent first; the rest are folded into one summary line. +9. **One-shot seam.** What one check needs from one server (the unread alerts and warnings, the array state, and how the attempt went) is behind a small interface, so the worker, and later a widget, share one code path. This change adds the interface and a test fake; the implementation that talks to the server arrives with the worker. + +Planned for the following changes, recorded here so the picture is complete: a periodic WorkManager job (every 30 minutes by default, 15 minutes to 3 hours selectable) initialised on demand so that WorkManager is never touched while the switch is off; the two existing read-only queries over one connection; fail-closed certificate trust and no prompts in the background; no foreground service, no exact alarms, no battery-optimisation exemption request; `FOREGROUND_SERVICE` stripped from the merged manifest; `POST_NOTIFICATIONS` asked for only when the user turns the switch on. + +## Consequences + +**Positive** + +- Users learn about a failing disk, an array that is not started or a degraded array without opening NOVA, with no relay, no push service, no Google services and no server plugin. +- The decision logic is pure and fully unit-tested before anything runs in the background, and the Overview card and a later widget share its rules. +- Nothing changes for users who leave the switch off. + +**Negative / trade-offs** + +- Android decides when a periodic job runs. Under Doze and OEM battery managers an alert can come late, sometimes by an hour or more, and on Android 13 and later an app that is not opened for 8 days is limited to about one run a day. +- WorkManager adds two permissions, `WAKE_LOCK` and `RECEIVE_BOOT_COMPLETED`, to every install, even with the switch off. It also merges `ACCESS_NETWORK_STATE`, which NOVA already declares, and `FOREGROUND_SERVICE`, which the worker change removes with `tools:node="remove"` because NOVA never starts a foreground service. The privacy policy has to name the two new ones and say the checks are active only while alerts are on. +- A notification is seen only if Unraid keeps it as unread (browser delivery on, the default). Users who turned that off get no alerts for that importance. +- A scheduled parity check raises one warning when it starts; "Alerts only" removes it but also drops warnings such as SMART or read errors. +- Raising a limit later (more than 300 remembered ids, more than five alerts per check) is a data-format and wording decision, not a free change. + +**Constraints on other work** + +- A biometric app lock (#323) must gate the UI only. If it bound the Keystore key to user authentication or to an unlocked device, background checks could no longer decrypt the key. +- Targeting Android API 37 needs the `ACCESS_LOCAL_NETWORK` permission for connections inside the home network; until then NOVA's target level (36) is unaffected. Such a target bump must treat a blocked local network as "cannot check", never as "server down". + +**Trigger to revisit** + +- Unraid ships a Web Push sender or a generic webhook agent (instant alerts without polling become possible). +- A widget needs a refresh of its own beyond this job. +- Users report that missing alerts for notifications that only reach the archive matter; reading the archive would then be added. + +## Alternatives considered + +**UnifiedPush through the user's own ntfy.** Unraid's agents send plain posts, while UnifiedPush requires RFC 8291 encrypted messages. Unraid has no such sender and the project excludes a relay or server plugin that could add one. Users who already run ntfy can get instant alerts with configuration only (Unraid's ntfy agent to their own server, read by the ntfy app); the documentation will say so. + +**Firebase Cloud Messaging.** Needs Google services and a sender the project would have to run. Excluded by the project's principles. + +**A foreground service holding the notification subscription open.** Needs a permanent notification, and since Android 12 a foreground service cannot be started from the background; the cost is far higher than a short periodic check. + +**Raising disk and pool problems from the array data as well.** Duplicates Unraid's own notifications and doubles every alert. The allow-list of two keys, with a test that fails when it grows, keeps this a deliberate decision. + +**No alerts, documentation only.** Leaves the users who asked without an answer; the opt-in design costs nothing for everyone else. + +## References + +- Issue #321 (alerts outside the app) and the design posted there. +- [ADR-0017](./0017-domain-split-queries-with-lifecycle-polling.md): the foreground-only polling rule this amends. +- [ADR-0035](./0035-apikey-store-decrypt-failure-semantics.md): a background check never resets keys. +- [ADR-0041](./0041-host-ssl-entry-and-self-signed-local-trust.md): background trust fails closed. diff --git a/docs/adr/README.md b/docs/adr/README.md index 4d60734c..78220504 100644 --- a/docs/adr/README.md +++ b/docs/adr/README.md @@ -51,7 +51,7 @@ ADRs live under `docs/` so the CI docs-only bypass applies — pure-ADR PRs comp | [0014](./0014-single-ci-run-per-pr.md) | Single CI run per PR — release workflow resolves through PR | Accepted | | [0015](./0015-promotion-requires-new-commit.md) | Promotion to a different version-string requires a new commit | Accepted | | [0016](./0016-long-running-apollo-client.md) | Separate Apollo client for long-running mutations | Accepted | -| [0017](./0017-domain-split-queries-with-lifecycle-polling.md) | Domain-split queries with lifecycle-aware polling | Accepted | +| [0017](./0017-domain-split-queries-with-lifecycle-polling.md) | Domain-split queries with lifecycle-aware polling | Accepted (amended 2026-11-13 by ADR-0048) | | [0018](./0018-gradle-cache-warm-on-main.md) | Populate the Gradle build cache on push to main | Reversed 2026-05-17 (no measurable CI speedup in practice) | | [0019](./0019-parallel-debug-release-jobs.md) | Split CI into parallel debug + release jobs | Accepted | | [0020](./0020-migrate-to-ksp2.md) | Migrate from KSP1 to KSP2 | Accepted | @@ -81,4 +81,6 @@ ADRs live under `docs/` so the CI docs-only bypass applies — pure-ADR PRs comp | [0044](./0044-container-detail-live-stats-overlay.md) | Surface live CPU/Mem/Net/Disk in the container detail sheet from the docker stats overlay | Accepted | | [0045](./0045-array-disk-display.md) | Array disk display — sleeping disks, per-disk thresholds, errors | Accepted (updated beta10 — 2026-05-30) | | [0046](./0046-update-via-browser-download.md) | Offer updates of the GitHub build as a browser download, without an in-app installer | Accepted | +| [0047](./0047-server-capabilities.md) | Detect the server's API version and what the API key may do | Accepted | +| [0048](./0048-opt-in-background-alert-checks.md) | Opt-in background alert checks (amends ADR-0017) | Accepted | | [0049](./0049-google-play-third-distribution-channel.md) | Google Play as a third distribution channel | Accepted | diff --git a/docs/local-build.md b/docs/local-build.md index 1ea58d52..bcdeb6ee 100644 --- a/docs/local-build.md +++ b/docs/local-build.md @@ -29,7 +29,9 @@ Run it before every push.
