Suggested reviewers: Merge Risk: 🔵 Low · up to An unusually large lockout interval can interrupt the PIN prompt, and the longer message still needs an on-screen layout check. These are bounded risks to address or accept before merging. 🚥 Pre-merge checks | ✅ 3 | ❌ 2❌ Failed checks (2 warnings)

Note Grok commenting on Quick's behalf. Evidence: FAIL. This PR changes what users see in the PIN prompt, but the Evidence section has no captures. It says before-and-after captures are "still owed." Missing:

Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.Parse the HTTP-date form of
Retry-After.If
Retry-Aftercontains a valid future HTTP-date,TimeInterval.initreturnsnil. The prompt then says “Try again later” although the server supplied a wait time. Parse both numeric seconds and HTTP-dates, then pass the remaining interval topinLockedOut. Based on learnings,Retry-Aftercan use either form.Source: Learnings

lockout messages fit without overlapping adjacent content; allow the line to
grow or reserve sufficient height for the supported number of lines on each
platform.
Review comments at @iosApp/iosApp/Screens/Profiles/ProfileTransitionError.swift:
- Line 28: Update the retryAfter handling before converting the rounded minutes
to Int: validate that the rounded value is within Int’s representable range, and
show the existing retry-later message when it is not; preserve the current
conversion for values that fit.

On CodeRabbit's unverified finding about the HTTP-date form of Posted with Claude Code (claude-opus-5-5) at the author's direction. |
A locked-out profile closed the PIN prompt and showed a generic error on the picker. The prompt now stays open and says how long to wait, from Retry-After rounded up to whole minutes, or "later" without the header. HTTPClient's acceptedStatuses now also applies to requests without a request identity, which is how the picker calls verify-pin. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A Retry-After of "inf" or "1e300" parsed as a number and trapped in the Int conversion; anything over a day now reads "Try again later". The PIN prompt's status line had a fixed height, so a wrapped lockout message could overlap the keypad; it now grows. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Problem
Closes #664
Related issue: Silo-Server/silo-server#2021
Validation tasks: none
The server locks a profile for five minutes after five wrong PINs and answers
verify-pinwith 429 andRetry-After. On iPhone, iPad, Apple TV and Mac, that 429 closed the PIN prompt and showed a generic error on the profile picker, with no hint of how long to wait. The prompt now stays open and shows "Too many incorrect PINs. Try again in N minutes."Approach
verify-pinaccepts a 429 and turns it into a newProfileTransitionError.pinLockedOut(retryAfter:). Its message roundsRetry-Afterup to whole minutes and falls back to "Too many incorrect PINs. Try again later." when the header is missing, not a number of seconds, or longer than a day. The wording matches the web app's.The profile picker's PIN prompt is the only caller of
verify-pin; it covers both choosing a profile and unlocking profile management. It shows the lockout message in place and keeps the prompt open.To read the header,
HTTPClient.requestData's existingacceptedStatusesoption now also applies to requests made without a request identity. The picker has no active profile, so its requests take that path. No other caller passesacceptedStatuseson that path, so nothing else changes.The lockout clears the entered digits, shakes the dots and fires the error haptic, as a wrong PIN does. The app shows no attempt counter, so nothing is counted.
Validation
Retry-After, 18 passed, 0 failed.SiloTVbuilds (compile only,CODE_SIGNING_ALLOWED=NO). Tests not run.Evidence
Evidence: not captured yet. This change alters what a user sees in the PIN prompt, and a capture needs a server with the lockout from Silo-Server/silo-server#2021. Before-and-after captures are still owed.
Surface and build: PIN prompt on iPhone, iPad and Apple TV.
Risks
None identified. A 429 from
verify-pinwas already an error; only its presentation changes. The prompt's status line now grows when the lockout message wraps; this was not checked on screen.Checklist
