fix: about page version unknown and link crash on Android (#213 )

Bug 1 – "App Version: unknown": PackageInfo.fromPlatform() throws because plugin registration is aborted mid-way by a Java Error (e.g. NoClassDefFoundError) that catch (Exception e) does not catch. Fix: change all 13 catch clauses in GeneratedPluginRegistrant.java to catch (Throwable e) and commit the file so it is used by release builds. Bug 2 – crash when tapping sharedinbox.de: url_launcher_android 6.3.25+ migrated to Pigeon 26, which throws a channel-error on some Android devices (same root cause as path_provider_android, already pinned). The onTapLink callback called launchUrl via unawaited() with no error handling, so the PlatformException became an unhandled async error and crashed the app. Fix: pin url_launcher_android <6.3.25 in dependency_overrides, and add a _launchUrl() helper with full try/catch that shows a SnackBar on error instead of crashing. New widget test verifies the snackbar path. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

 - Vault itself becomes a security-critical single point of failure.
 - Operational overhead likely disproportionate for a small single-developer project.

+### Option 5: Encrypted secrets file (age) — **implemented**
+
+Store all production secrets in a file (`secrets.env`) that is encrypted with
+[age](https://age-encryption.org/) into `secrets.age`. The encrypted file is
+committed to the repository. Only the age private key — a single string — is
+stored in Codeberg as `SECRETS_AGE_KEY`. Any CI job or developer with the key
+can decrypt the file and obtain all secrets.
+
+**How it works:**
+
+1. Generate a key pair once:
+   ```bash
+   age-keygen -o ~/.config/age/sharedinbox.key
+   age-keygen -y ~/.config/age/sharedinbox.key > .age-public-key
+   ```
+2. Copy `secrets.env.example` to `secrets.env`, fill in all values, then encrypt:
+   ```bash
+   scripts/secrets-encrypt.sh   # reads public key from .age-public-key
+   git add secrets.age && git commit -m "chore: update encrypted secrets"
+   ```
+3. Add the private key content as `SECRETS_AGE_KEY` in Codeberg repository secrets.
+4. CI jobs call `scripts/secrets-decrypt.sh` (with `SECRETS_AGE_KEY` set) before
+   any step that needs production credentials. The script writes each variable
+   to `$GITHUB_ENV` so subsequent steps see them automatically.
+
+**Keeping local and CI in sync:**
+When you rotate a secret locally, update `secrets.env`, re-run
+`scripts/secrets-encrypt.sh`, and commit the new `secrets.age`. CI will pick
+up the fresh secrets on the next push — no manual CI variable updates needed.
+
+Multi-line values (SSH keys, certificates) must be stored as a single line
+with `\n` escape sequences inside double quotes. Example:
+```
+SSH_PRIVATE_KEY="<header>\n<base64 key body>\n<footer>"
+```
+
+**Pro:**
+- One secret (`SECRETS_AGE_KEY`) in Codeberg instead of many.
+- Encrypted secrets are version-controlled — rotating a secret is a git commit.
+- Local dev environment and CI always use the same encrypted source of truth.
+- `age` is a simple, audited tool with no server infrastructure.
+- The private key never appears in workflow files or logs.
+
+**Con:**
+- `secrets.age` exposes the list of variable *names* (visible in the encrypted
+  file if the format leaks, though not the values).
+- All credentials share a single key — compromising `SECRETS_AGE_KEY` exposes
+  everything at once.
+- Key rotation requires re-encrypting `secrets.age` and updating the CI secret.
+
 ### Recommendation

-**Option 1** (runner-level env vars) or **Option 2** (secret files) are the pragmatic starting point for a single self-hosted runner. They require no new infrastructure and move all production secrets off Codeberg immediately.
+**Option 5** (encrypted secrets file) is now the active approach. It reduces
+Codeberg secrets to exactly two categories:
+- **Dagger access credentials** — `DAGGER_STUNNEL_URL`, `DAGGER_CA_CERT`,
+  `DAGGER_CLIENT_CERT`, `DAGGER_CLIENT_KEY`.
+- **Master key** — `SECRETS_AGE_KEY`.

-**Option 3** (Dagger host as orchestrator) is worth considering once the trigger SSH key replaces all other secrets in Codeberg — it offers the cleanest security boundary at the cost of reduced CI observability.
+**Option 1** (runner-level env vars) or **Option 2** (secret files) remain
+valid if you prefer not to commit an encrypted file to the repository.

-**Option 4** (Vault) becomes worthwhile if the project grows to multiple runners or team members who each need audited access to deploy credentials.

Thomas SharedInboxandClaude Sonnet 4.6	bc91c0db52	fix: about page version unknown and link crash on Android (#213 ) Bug 1 – "App Version: unknown": PackageInfo.fromPlatform() throws because plugin registration is aborted mid-way by a Java Error (e.g. NoClassDefFoundError) that catch (Exception e) does not catch. Fix: change all 13 catch clauses in GeneratedPluginRegistrant.java to catch (Throwable e) and commit the file so it is used by release builds. Bug 2 – crash when tapping sharedinbox.de: url_launcher_android 6.3.25+ migrated to Pigeon 26, which throws a channel-error on some Android devices (same root cause as path_provider_android, already pinned). The onTapLink callback called launchUrl via unawaited() with no error handling, so the PlatformException became an unhandled async error and crashed the app. Fix: pin url_launcher_android <6.3.25 in dependency_overrides, and add a _launchUrl() helper with full try/catch that shows a SnackBar on error instead of crashing. New widget test verifies the snackbar path. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-05-24 17:15:19 +02:00
Thomas SharedInboxandClaude Sonnet 4.6	839a3c63f9	feat: keep secrets in sync via age-encrypted master key (#208 ) Store all production secrets encrypted in secrets.age (committed to the repo) using age. Only one secret needs to be in CI: SECRETS_AGE_KEY. When a secret changes locally, update secrets.env and re-run scripts/secrets-encrypt.sh to commit a new secrets.age. CI picks up the updated secrets automatically on the next push — no manual CI variable updates required. Changes: - scripts/secrets-encrypt.sh: encrypt secrets.env → secrets.age - scripts/secrets-decrypt.sh: decrypt secrets.age → GITHUB_ENV (CI) or eval-safe export block (local) - scripts/test_secrets.sh: encrypt/decrypt round-trip tests - secrets.env.example: template documenting all production secret keys - ci/main.go: add CheckSecrets function (runs test_secrets.sh via Dagger), wire into Check(), update Graph(); add age to toolchain apt packages - .forgejo/Dockerfile: add age package - .forgejo/workflows/deploy.yml: replace per-secret CI references with a single "Decrypt production secrets" step using SECRETS_AGE_KEY - flake.nix: add age to dev shell - Taskfile.yml: add check-secrets task, include in check-fast - .gitignore: ignore plaintext secrets.env - DAGGER.md: document Option 5 (encrypted secrets file) as active approach Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-05-24 16:32:27 +02:00

Thomas SharedInboxandClaude Sonnet 4.6	881a240155	fix: probe scanner method channel to detect MissingPluginException (#204 ) The previous pre-flight check called ctrl.start() without ctrl.attach(), causing MobileScannerController to time out after 500 ms with controllerNotAttached on every device — the scanner never worked even when the plugin was present. Replace with a direct invokeMethod('state') probe on the scanner channel. MissingPluginException (thrown when the plugin is not registered) is the exact error from the crash report; all other errors are surfaced by the MobileScanner widget's own error builder. Also add widget tests for the AccountReceiveScreen step-2 import flow (text fallback, successful import, invalid-QR error) which were previously untested.

Thomas SharedInboxandClaude Sonnet 4.6	77e581299d	fix: filter out schedule/deploy workflow runs in CI checks _latest_main_ci_run() was using event != pull_request which still matched deploy.yml schedule runs when their prettyref == "main", blocking the loop from picking up new issues. _latest_ci_run_for_branch() had the same issue: the else branch matched any non-pull_request event including schedule runs. Both functions now explicitly filter for event == "push" only. Tests updated: rename _latest_ci_run → _latest_main_ci_run, mock _open_issue_prs to prevent real API calls in unit tests, and update _find_pr_for_branch side_effect to reflect the upstream post-merge PR-still-open verification check.

Thomas SharedInbox	3f946dfca0	fix: switch Play Store upload from httplib2 to requests The Play Store AAB upload was failing with httplib2.error.RedirectMissingLocation when Google's API returned a redirect during the resumable upload initiation.

Thomas SharedInboxandClaude Sonnet 4.6	c517f604e0	test: update deploy_playstore tests for requests-based transport The previous tests patched google_auth_httplib2 and googleapiclient which no longer exist in the new implementation.

Thomas SharedInboxandClaude Sonnet 4.6	7d393ec818	fix: switch Play Store upload from httplib2 to requests httplib2 treats 308 Resume Incomplete responses (used by Google's resumable upload API) as redirects and raises RedirectMissingLocation when the response lacks a Location header. Switch to google.auth.transport.requests.AuthorizedSession + direct HTTP calls so the upload uses the requests library, which handles 308 correctly.

Thomas SharedInboxandClaude Sonnet 4.6	7715190cbf	fix: retry AAB upload on RedirectMissingLocation with exponential backoff Adds a 3-attempt retry loop around the resumable AAB upload that catches httplib2.error.RedirectMissingLocation (a transient network error) and retries with exponential backoff (10s, 20s). A fresh MediaFileUpload is created on each attempt because resumable upload objects cannot be reused after failure. Also adds TestUploadRetry covering the retry path.

Thomas SharedInboxandClaude Sonnet 4.6	80cde04d87	fix: retry AAB upload on RedirectMissingLocation with exponential backoff (#186 ) Wrap the resumable bundle upload in a loop of up to _MAX_UPLOAD_ATTEMPTS (3) attempts. On httplib2.error.RedirectMissingLocation, recreate MediaFileUpload (resumable uploads cannot reuse the same object) and wait 10 s / 20 s before retrying. After all attempts are exhausted, raise RuntimeError chained to the last exception. Add tests covering the retry path, backoff delays, fresh MediaFileUpload on each attempt, and exhaustion.

Thomas SharedInboxandClaude Sonnet 4.6	fb6f2cca68	fix: add timeout and retries to Play Store upload (#185 ) Switch deploy_playstore.py from requests/AuthorizedSession to the googleapiclient.discovery client with google-auth-httplib2, so that AuthorizedHttp(timeout=300) enforces a hard socket timeout on all requests and num_retries=3 on every .execute() call enables automatic retries for transient failures. Update flake.nix and ci/main.go to install the new dependencies (google-api-python-client, google-auth-httplib2, httplib2) instead of the old google-auth + requests pair.
