fix: clear WAL locks using actual DB path from connection string

fix: explicitly set app_port=7860 in HF Space config

revert: port back to 7860 - HF Space uses 7860

fix: change port from 7860 to 8080 - HF Space proxy expects port 8080

fix: set ASPNETCORE_ENVIRONMENT=Production in Dockerfile, create /data/data dir

fix: auto-create DB directory on startup to prevent crash on HF Space

fix: remove UseHttpsRedirection for HF Space HTTP-only env

feat: optimize canvas load and save using lazy loading and delta upserts

fix: treat null/empty SubscriptionTier as Free tier in all limit checks

feat: include daily AI generation count in user response DTO

Implement custom templates and subscription tiers backend changes

Refine strategist prompts for conversational tone, adaptive sizes, and correct chronological chaining

Optimize prompts for recursive roadmap generation and add goal templates

fix: enforce strict node type rules (sketch/habit/condition) in prompts

chore: support parallel and sequential subgoal structures in system prompts

chore: update system prompts with refined subgoal/sequential rules

fix: enforce parent node creation and subgoal relationships for subtasks

feat: integrate FreeDeepseekAPI background proxy and routing in AIService

feat: add chat history support to AI strategist assist

feat(AI): map subgoal to subgoals-source-right and instruct model to chain sequential subtasks

feat(AI): add retry loop with exponential backoff for transient HTTP status codes (503, 429, 500)

feat(AI): refine prompts for natural conversational agent behavior, strict habit guidelines, and subtask breakdown

fix(AIService): robust model name validation to fallback to gemini-2.5-flash if configured model looks like API key

debug: include model name in Gemini API exception

fix(AIService): strip models/ prefix from Gemini model name

fix

gemini integration

fix: resolve foreign key constraint error when saving edges

fix(api): fix EF double-track bug in UpdateFromAgent causing nodes to be deleted but not re-inserted - reorder SaveFullGraphAsync BEFORE UpdateAsync to avoid DbContext tracking conflict on same Graph entity

feat(api): add server-side QuestSchema payload validation - block JSON-fragment labels, duplicate IDs, dangling dependsOn, self-refs, invalid status/color, node/label limits

feat: Add dynamic UpdateFromAgent endpoint to allow programmatical roadmap editing

feat: Upgrade AutoLayoutEngine to support rich node generation (color, status, progress, tags, subgoals, etc.)

fix(agent-canvas): handle spaces in base64 claim token dynamically in VerifyClaimToken

fix(agent-canvas): share claimed canvas back to system agent with Edit permission automatically

fix(agent-canvas): retrieve system agent user ID dynamically by email to prevent Guid mismatch

fix(agent-canvas): change initial canvas ownership to system agent account to support unclaimed state

Auth: Add AllowAnonymous claim check endpoint

Auth: Implement cryptographic one-time claim token verification and ownership transfer

Layout: Swap axes to flow top-to-bottom for sequential and horizontal for sub-blocks

Fix: Check user email first in GetToken to prevent unique key violation in SQLite

Fix: Drop stale EFMigrationsLock and close connection to prevent rolling update deadlock

Fix: add robust user existence checks to prevent SQLite Foreign Key errors

feat: enable EF core migrations automatically on startup to update SQLite production DB schema

fix: resolve EF Core Edge mapping GraphId ForeignKey constraint violation in SaveFullGraphAsync

feat: implement QuestSchema DTO, AutoLayoutEngine and AgentCanvasController for LLM Agent Skill integration

fix: optimize SQLite write performance and re-enable WAL mode to resolve database locking

fix: forcefully disable automatic migrations and clear SQLite lock files to bypass server hang

fix: restore database filename and add emergency cleanup logic to resolve migration hangs

fix: revert to stable SQLite settings and enforce 5MB payload limit to prevent disk I/O errors

fix: apply aggressive SQLite stability settings (EXCLUSIVE lock, MEMORY journal) to resolve disk I/O errors on HF Spaces
