Reliability toolkit for Google Flow
HAR forensics · live monitor · optional self-pacing — not a bypass tool
Flow Fixer helps you see why Google Flow shows “unusual activity” or “too quickly” when you’re clicking Generate / Retry like a normal user.
Core observation: Flow scores reCAPTCHA risk per generate HTTP call, while the UI often turns one click into N parallel generate calls (multi-output ≈ 4; Retry-All often 12–20). Pass rate can collapse by fire-order inside a burst. Optional AUTO-THROTTLE paces your own clicks so you don’t overspeed into a sticky lockout.
It does not forge reCAPTCHA, automate generation, or evade abuse systems. Processing is local in your browser or on your machine.
Technical write-up: docs/ENG_BRIEF.md · Limitations: docs/LIMITATIONS.md · Privacy: PRIVACY.md · Security: SECURITY.md
Extension UI: hard unusual-activity gate → auto downshift to Molasses + cool-down. Full speed ladder + live classify.
What users see in Flow: failed cards with Retry still available — retries add more scored HTTP calls.

| Feature | Notes |
|---|---|
| Live soft / hard / filter classification | From generate responses |
| Fan-position pass rates | UI burst shape |
| AUTO-THROTTLE | Optional; default on. Paces/serializes your generate calls |
| Speed ladder | Molasses → Casey Jones (see below) |
| Export JSON / Copy report | Last 500 events; project IDs redacted; no prompts/tokens |
| Diagnostics strip | Inject heartbeat + net hits; project UUIDs redacted for safer screenshots |
| Settings persist | Auto-throttle / monitor / gear survive browser restart |
AUTO-THROTTLE off = monitor only (no pacing).
Casey Jones = full parallel fan-out — will trip soft/hard quickly under load; use intentionally.

Markdown summary |
Requires Python 3.10+.
Pass rate by fire-order inside a burst (gap ≤ 2s). First call often lives; the tail often dies.
| Observation | Interpretation |
|---|---|
| Fresh unique reCAPTCHA tokens on failed calls | Not simply “stale captcha” |
| Same creative payload, mixed 200 / 429 | Timing/burst position matters |
| Soft vs hard are different reason codes | Two machines, not one |
| Hard can stay sticky for many minutes | Short “try again” guidance may be incomplete |
More detail: docs/ENG_BRIEF.md · Operating tips: docs/OPS_DOCTRINE.md · Wire map: docs/INTERNAL_MAP.md
| Gear | Idea | Approx gap |
|---|---|---|
| 🧊 Molasses | Way under typical throttle | ~9s |
| 💧 Water | Calm | ~4.5s |
| 🚶 Brisk Walk | Human pace | ~2.5s |
| 💼 The Job | Default work cadence | ~1.2s |
| 🎸 Highway Star | Spicy but serialized | ~0.6s |
| 🐎 Black Beauty | Fast | ~0.3s |
| 🚂 Casey Jones | Full parallel | none |
Auto shift: soft → downshift; hard → Molasses + cool-down; clean OK streak → gradual upshift.
