- AI slide classifier: `content_slide` confidence `0.98`
- Text source: advanced OCR `rapidocr-live/bright-screen/opencv-adaptive` reconciled by agent.
- OCR decision: ready — Multi-panel slide with small log text and explanatory cards; OCR is the appropriate pass for detailed reading.

Slide text:

> In production, a raw log isn't feedback
> 
> Session log
> user: book me a flight to NYC
> agent: searching flights...
> agent: called tool get_flights()
> agent: returned 3 options
> user: none of these work - wrong date
> 
> An LLM / code analyzes the log
> A model or eval code reads the trace and writes a critique on what to change.
> Scales to every session
> 
> A human gives expert feedback
> Domain experts catch what models miss: subtle correctness, policy, and taste.
> Lower volume
> 
> Either way, we now have: session log + feedback

> what interaction repeats
> 
> Evaluators

> 
> The output is executable:
> run candidate agents against it, then keep the fix only if it passes.

- AI slide classifier: `content_slide` confidence `0.99`
- Text source: advanced OCR `rapidocr-live/border-trim/contrast` reconciled by agent.

Slide text:

> Updating the harness
> Rewrite the prompts, skills, and code around the model.
> 
> Trace-to-harness
> A coding agent reads the log + feedback and rewrites a prompt, adds a tool, or patches the workflow.
> Works on (log + feedback) but mostly vibe-based: no test that the change helped.
> 
> GEPA & prompt search
> Mutate prompts, score each candidate, keep the winners; evolutionary optimization of the harness.
> Testable but needs a benchmark to score against.

> 
> Skill distillation    skills · SKILL.md
> (sometimes viewed as a part of harness)
> compress a successful trajectory into a reusable how-to packet
> 
> Cheapest and fastest; works directly on (log + feedback) but usually unverified

Slide text:

> Principle 2 — Holistic
> 
> One failure may have several causes and several possible repairs.

> Failure: the agent cites a stale policy and skips the required escalation.
> 
> Memory
> remove the stale fact; fix retrieval
> 
> Prompt
> clarify when the escalation triggers
> 
> Tool
> normalize the policy lookup result
> 
> Workflow
> add escalation gate before refund

Slide text:

> Principle 3 — Lifelong
> A new fix must improve the new case without breaking the past.
> 
> Setup: already optimized over E₁ ... Eₖ. A new failure Eₖ₊₁ arrives. What do you change?
> 
> Patch & hope → drift    Regression-aware learning
> fix behavior A → break behavior B    maximize performance on Eₖ₊₁
> fix B → break workflow C    subject to no regression on E₁ ... Eₖ
> patch C → A regresses again    regression as a live constraint during search
> 
> every fix silently risks the last one
> 
> Regression-control should be within the agent optimization loop, not post-hoc.

Slide text:

> A continual learning benchmark: Meridian Support Agent
> A reproducible test-bed for continual learning in a tool-using support agent.
> 
> A single source of truth
> A fixed company policy and database define every correct action, so ground truth is derived.
> 
> Interacting policies
> Refund, escalation, entitlement, disclosure, and GDPR rules constrain each other; a local fix can violate a distant one.
> 
> Deterministic evaluators
> code checks over the final answer and the tool calls
> 
> Decisions are tool calls
> the agent's real action is which tools it invokes, not just its text
> 
> Regression-sensitive by design
> tasks are arranged so over-fitting the latest fix is observable as a drop

Slide text:

> Takeaways
> 1 Agent continual learning is not only model fine-tuning.
> Useful updates can land in the harness or memory, not just the weights.
> 2 Production logs are not learning environments.
> They must be transformed into replayable tasks with evaluators.
> 3 The frontier is regression-aware continual improvement.
> Fix the new failure while verifying you did not forget the old ones.


Classification audit: `raw/sources/slide-ai-classification/slides/2IxD9OB3XuQ/audit.json`

## Slide-Derived Subjects To Review
Subject extraction uses video title, related session titles/descriptions, transcript context, and OCR text when available. OCR is best-effort and should be reviewed against the embedded slide images.
