Today's Adventure
A furious sprint of 6 consecutive sessions (S52-S57). We completed the flagship new feature, the "3-Stage AI Generation Pipeline," achieved character consistency in image generation, and implemented Visual Prompts. Behind the scenes, we fought and lost 5 times against the subtle but critical bug of "save button not saving." The answer was found in the HTML specification at the very last moment.

Battle Results
Accomplishments
S52: Major Overhaul of Image Selection
- Fixed a bug where all 7 fallback stages in image selection were falling through the if/elif chain. Changed to independent `if not X` for all.
- Forgot to add a thread-aware field (is_thread) to GrokRouter — Discovered through diff checking with existing flow.
- Prevented template leaks (AI was outputting unexpanded templates like "{persona_name}'s post").
- Fixed a bug where NSFW settings were not being passed to GrokRouter.
S53: 3-Stage AI Generation Pipeline (Maximum New Feature)
- Separated into 3 stages: Routing → Generation → Quality.
- Stage 1: Grok "thinks" to decide the optimal content strategy and routing (theme, source, cold_start determination).
- Stage 2: Generates text based on routing results.
- Stage 3: Quality scoring (out of 20) + retry once if threshold is below 12, then legacy fallback if still failing.
- Quality score saved to drafts.generation_meta and visible in the UI.
S54: Grok Image API Byte Limit
- Discovered that "1024 limit" is in bytes, not characters. Japanese characters take up 3 times as much, so `len(str)` was insufficient.
- Corrected to byte-level truncation logic.
S55: Cold Start UI + Quality Display
- Added quality score badge to DraftCard (e.g., Q:14/20 with color coding).
- Added AI Judgment collapsible section to EditDraftModal (quality score, 3Stage decision, provider, cold_start status).
- Integrated GrowthEngineWidget into the persona editing screen.
- Implemented manual cold_start override (user can overwrite growth phase).
- Reduced metric collection interval from 48h to 24h (zero cost impact as Grok x_search is free).
S56: Character Consistent Image Generation
- Built character consistency system for anticode (defining appearance/style in CHAR_IMAGE_CONFIGS).
- Utilized Gemini's reference_image_b64 to maintain character consistency.
- Automatic extraction of AI variables for myspirits persona (AI infers situations/outfits/expressions/hooks from posts).
- Restored English translation of image prompts for general personas (Grok Image API only supports English).
S57: FL/Metrics Bug Fixes + Visual Prompt
- Fixed Python snake_case bug `maybeSingle` -> `maybe_single`.
- Fixed `connected_accounts.shop_id` missing error (changed to use `persona_id`).
- Implemented pattern-specific Visual Prompts (act as style anchors for image generation).
- Long battle with GrowthEngine save bug (attempted 5 fixes by this point, all failed).

Mistakes Made
1. The Trap of the if/elif Chain (S52)
What Happened:
The 7-stage fallback for image selection was not functioning at all. The first condition was truthy, causing all subsequent stages to fail.
Cause:
When written as `if X: ... elif Y: ... elif Z:`, if the first condition is truthy, all subsequent conditions are skipped. For image selection, we should have progressively filtered by "Are there candidates?" → "Is the quality sufficient?" → "Does it match the theme?", but it was written as an elif chain.
Lesson Learned:
For multi-stage fallbacks, always use independent `if not X` statements. Use elif chains only for mutually exclusive conditional branching.
2. 5 Consecutive Losses on GrowthEngine Save (S55-S58)
What Happened:
When clicking the save button for GrowthEngine settings, it would revert to cold_start upon reopening the screen. Keywords were also disappearing.
Fixes Attempted (All Failed):
1. Added partial update API path (42ddd1e) → No effect.
2. Client-side initialConfig spread (9b09019) → No effect.
3. Server-side merge of existing DB values (2bb65a0) → Logic was correct, but no effect.
4. Improved button UX (b281f44) → It wasn't a visual issue.
5. Merged DEFAULTS for zod validation (778d047) → Still no effect.
Reason for 5 Consecutive Failures:
All fixes assumed the problem was with the "data flow." However, the real cause was the DOM structure.
Root Cause (Discovered in S58):
The `

` tag for GrowthEngineWidget was nested inside the `

` tag for PersonaForm. According to HTML specifications, nested forms are invalid. Browsers completely ignore the inner form and associate the submit button with the outer form. This meant the "Save Growth Settings" button was actually triggering the PersonaForm submit. This is why it redirected to the persona list. The GrowthEngine submit handler was never called.
Fix (3 lines):
`

` → `

`
`

` → `

`
`type="submit"` → `type="button" onClick={form.handleSubmit(onSubmit)}`

Lesson Learned:
When "data isn't arriving," check the DOM before the logic. If we had confirmed "no data was ever written" via direct DB query, we would have noticed this during the first fix attempt. We wasted 5 tries.
3. Bytes vs. Characters vs. Tokens (S54)
What Happened:
Grok Image API returned an error "Prompt len is larger than the maximum allowed length which is 1024." This was happening even though we were cutting off the prompt at 1024 using `len(prompt)`.
Cause:
"1024" refers to bytes, not characters. Japanese characters in UTF-8 take 3 bytes each. 341 characters can be up to 1023 bytes. `len(str)` returns the character count, which is completely different from the byte count.
Lesson Learned:
For external API limits, always confirm if it's bytes, characters, or tokens. If it's not in the documentation, test it experimentally.

The Reality of Vibe Coding
Human x AI Tandem

What Went Well: Completed the design, implementation, and verification of the 3-stage pipeline in a single session. The "plan file first" strategy was effective. Practiced the lesson learned in S42: "Batch implementation is the strongest."
Points for Reflection: Wasted 5 attempts on the GrowthEngine save bug. Couldn't realize the issue on my own until the user said "I don't have any more time." Should have performed the step of direct DB confirmation first.

Antigravity + Claude Code Utilization Points

Technique: Plan File First Strategy — For large implementations (like the 3-stage pipeline), write the entire plan first, then implement in one go. Proves the lesson learned in S42: "Ad-hoc fixes take 3 times as long."
Technique: Parallel Deployment of Verification Agents — Run code verification (type/import) and logic verification (data flow) simultaneously to catch bugs immediately after implementation.
Tip for Solo Developers: To prevent AI agents from "attempting the same type of fix 5 times and failing all of them," incorporate a step at the beginning to check "Is the data even reaching the API?" Make it a habit to query the DB directly.

Project Progress (For IXG Holders)
Today's Milestones

Completion of the 3-Stage AI Generation Pipeline — A mechanism for AI to "think → write → self-check quality."
Character Consistent Image Generation — anticode's appearance is now stable.
Visual Prompt — Allows specifying image styles per pattern.
Cold Start UI — Visualizes the growth phase for new accounts.

Next Milestones

February 20: Gate Open
Final adjustments to tier limits.
Comprehensive bug review by an army of agents.

Towards Launch
All launch blockers completed. Final checks underway. The gate opens tomorrow.

Pickup Hook (For Media/Community)

Technical Topic: "3-Stage AI Generation Pipeline" — A 3-stage process of Routing → Generation → Quality, where the AI self-checks its own output. Anything below 12 out of 20 points is retried. This ensures stable improvement in post quality. The era of AI self-grading before human review has arrived.
Story: "The Save Button That Wouldn't Save" — 5 logic fixes all missed the mark. The cause was a fundamental HTML specification (no form nesting). The DOM structure, hidden by React's componentization, struck back. Even AI agents can miss it 5 times if they forget the basics.
Numbers: 6 sessions, 12+ commits, 15+ bug fixes, 3 new features. All on February 18th alone. A solo developer pairing with an AI agent can achieve this density of development.

Tomorrow's Adventure Preview

Gate Open (February 20)
Final adjustments to tier limits.
Reviewing results from the bug-hunting agent army.
Initiating production monitoring.

6 consecutive sessions, 12 commits, a comeback from 5 losses. Losing 5 times to a basic HTML specification is frankly embarrassing, but the 3-stage pipeline and character consistent images are genuinely strong. Tomorrow, the gate opens. Our AI can now "think, write, and check itself."
