Nothing to show on screen: these failures already told the user (a toast, an error state) or were worked around, and that doesn't change. What changes is that a copied debug report now has them. Before, each one went only to the developer console, so a user who sent us a report after hitting one sent us nothing about it.

The places came from an audit for failures a user would feel that leave no trace in a report. Each now calls AppErrorReporter with its error and stack:

• A drawing that can't be read when a page loads from disk, the cloud or an old .ica file. It is left off the page, as before, and now leaves an error entry naming its kind and position ("drawing 2 of 2, type lineDrawing"), never its content. Keeping the drawing and telling the user waits until a report shows this happening: cloud drawings are never deleted by it, and local pages only meet this decoder when they were written by old cloud builds or come from an .ica import.
• Reading the cloud library, the open cloud strategy, or keeping its offline copy. A viewer reads a shared strategy with the link's code, and a server error can quote its arguments, so the code is replaced first.
• Copying items or lineups to another page; copying images when duplicating a strategy.
• Discord and email sign-in, sign-up, password reset, setting a password, sign-out, and the Supabase token refresh. The token-related ones pass through redactAuthDiagnosticText, as the auth callback already does.
• Opening a replay, or reading one into the replay list, including a replay decoder that can't run at all.
• Opening, previewing or adding a share link. The link code is replaced with <link code>: it's what opens the strategy.
• A link that fails to reach the running app (the initial link or the stream).
• Update checks (the version file and the Windows Store).
• Media upload and attach failures now keep their stack.

Emails are kept out of everything the log keeps. Supabase's sign-up and reset errors can quote the address that was refused, so the reporter replaces email addresses (apostrophes included) in every entry's message, error and stack before it is kept or copied. It looks outward from each @ instead of matching from every character: the first version took minutes on a one-megabyte entry, which the existing log-rotation test caught.

Left as is: failed imports log the file's path. That's how the report already works (only the home folder becomes ~, so the account name stays home), and the path is what tells us which file failed.

Checked

• A test loads a page with one good and one broken drawing: the good one loads, and the log has the error entry with its stack.
• A test feeds a Supabase-style error quoting an address: no @ survives. Another runs a 2 MB entry through the email check in under 2 seconds.
• flutter test passes in full (3,786 tests) before the email change; the services tests after it.
• In the running web build: a sign-in with a wrong password printed [auth] warning: Email/password sign-in failed.: AuthApiException(message: Invalid login credentials, statusCode: 400, code: invalid_credentials), the same entry the report gets, with no address anywhere in the output. The other paths are log calls on failures that were already caught; tests and CI cover them.
• Merged with main after Say what led up to an error in the debug report #559; the related tests pass on the merge.

Walkthrough

Application failure paths now report through AppErrorReporter. Stored debug logs sanitize recognized email addresses. Existing operation outcomes remain in place, with additional reporting for drawing and replay decode failures.

Changes: Error reporting and sanitization

Layer / File(s)	Summary
Log sanitization and tests lib/services/app_error_reporter.dart, test/services/report_without_emails_test.dart	Stored messages, errors, and stack traces are sanitized for recognized email addresses. Tests check redaction and processing time.
Startup, authentication, and update errors lib/main.dart, lib/providers/auth_provider.dart, lib/const/update_checker.dart	Deep-link, authentication, version-check, and Windows Store failures now use AppErrorReporter. Existing error handling and return values remain in place.
Collaboration, sharing, and strategy errors lib/providers/collab/cloud_media_upload_queue_provider.dart, lib/providers/collab/remote_library_provider.dart, lib/providers/collab/remote_strategy_snapshot_provider.dart, lib/providers/share_link_provider.dart, lib/providers/strategy_provider.dart	These failure paths now report warnings with error details and stack traces. Share-link reports redact the link token.
Drawing and replay decode errors lib/providers/drawing_provider.dart, lib/providers/replay_library_provider.dart, lib/replay_view.dart, test/services/dropped_drawing_report_test.dart	Drawing decode failures are reported per item while decoding continues. Replay failures are reported with their existing fallback handling.

Change: Feature

Merge Risk: Low · up to bbb25

This PR adds error details to the copied debug report. Some unusual email forms, and in rare error cases a share-link token, could still appear in a report that users copy and share. Decoder-loading failures during replay probing also still go unreported. Normal app behavior is unaffected, so this is mergeable once the owner is aware of these gaps and decides whether to fix them first.

Explanation

The title "Put failures users feel into the debug report" matches the main change. The PR adds error and stack reporting through AppErrorReporter for user-facing failures (drawings, cloud library and strategy operations, copy operations, authentication, replay, share links, update checks, media uploads) so they appear in the copied debug report. The title is specific enough for a teammate scanning history, though it is somewhat informal and does not mention the email redaction, which is a secondary part of the change.

- Around line 835-836: Update the remote snapshot read and subscription warning
paths for fetchShell, watchShell, fetchPageSnapshot, and watchPageSnapshot to
replace the received _shareToken with <link code> in both the error and stack
trace before calling AppErrorReporter.reportWarning. Follow the existing
redaction behavior in ShareLinkProvider._reportFailure; preserve the warnings
and their existing reporting flow.

_Library.instance failure-handling path to report operational failures before
returning them, reusing the existing warning mechanism. Preserve deliberate
exclusions for cancellation and unsupported formats, and keep the existing

regression cases confirming complete redaction of these addresses and no partial
disclosure in persisted diagnostics or copied reports.

Redact complete local parts, including quoted addresses.

For "sam smith"@example.com, the closing quote stops the backward scan immediately. start == at, so the complete address remains in the stored error and copied report. For sam.o'neil@example.com, the scanner leaves sam.o' visible. Both local-part forms are permitted by RFC 5322. (datatracker.ietf.org)

Extend the scanner to cover these forms without restoring unbounded matching. Add regression cases for complete and partial disclosure.

Based on learnings, redact personal data before diagnostic output is persisted.

Apostrophes fixed in 215c45d (sam.o'neil@example.com is now replaced whole, with a regression case). Quoted local parts like "sam smith"@example.com are left: addresses like that almost never occur in practice, and catching them means scanning across spaces and quotes.

[coderabbitai]

@SunkenInTime Thanks for fixing the apostrophe case. I understand the decision to leave quoted local parts unchanged. Those addresses can still appear in persisted logs and copied reports, so I’m not marking the finding as addressed.

Learning: Within repository "SunkenInTime/icarus", only for files matching one of ["lib/services/app_error_reporter.dart"]: In lib/services/app_error_reporter.dart, AppErrorReporter.withoutEmails intentionally leaves quoted local parts such as `"sam smith"@example.com` unredacted. The maintainer chose this limitation because those addresses are rare in practice and handling them requires scanning across spaces and quotes. When reviewing diagnostic privacy, account for this accepted limitation and do not assume every email address is sanitized before persistence or copying.
