[BOT ISSUE] Perplexity: mark r1-1776 as deprecated (retired August 2025)

[github-actions]

Summary

The r1-1776 model was officially retired by Perplexity on August 1, 2025, replaced by sonar-reasoning-pro. The catalog entry at line ~2925 has no deprecated or deprecation_date fields. Without these fields, markModelsPastDeprecationDate() in packages/proxy/schema/models.ts will not auto-flag it as deprecated, and the model will continue to appear in the UI despite being unavailable.

Affected Model

Model ID	Gap	Line
r1-1776	Missing deprecated: true and deprecation_date	~2925

Current catalog entry:

"r1-1776": {
  "format": "openai",
  "flavor": "chat",
  "input_cost_per_mil_tokens": 2,
  "output_cost_per_mil_tokens": 8,
  "displayName": "R1 1776"
}

Verification

Field	Source	URL
Retired August 1, 2025; replaced by Sonar Pro Reasoning	Perplexity changelog	https://docs.perplexity.ai/changelog
Not listed on current models page (only sonar, sonar-pro, sonar-reasoning-pro, sonar-deep-research are active)	Perplexity models documentation	https://docs.perplexity.ai/docs/agent-api/models

Cross-source confirmation: The Perplexity changelog explicitly states r1-1776 was retired on August 1, 2025. The current models documentation page does not list r1-1776 among active models, confirming it is no longer available.

The sonar-reasoning model in the catalog already has correct deprecation markers ("deprecated": true, "deprecation_date": "2025-12-15"), so this pattern is established for Perplexity models.
