Pair lecture slides with the explanation that belongs to each page

Proposed inputs

1. Name

   Deck and transcript

   Owner

   Learner or lecturer

   Minimum scope

   One authorized deck and corresponding timestamped text.

   Quality check

   Check edition, page count and which session the transcript covers.

2. Name

   Review boundaries

   Owner

   Lecturer or learner

   Minimum scope

   Included time window and pages to exclude.

   Quality check

   Identify skipped slides and any personal classroom discussion.

Access and setup — proposed or unknown

Proposed minimum

1. Preserve source files and prepare an annotation ledger before any rendering. Use a separate review output directory.

Compatibility unknowns

1. Unknown: transcript accuracy, PDF page geometry, font coverage and the installed rendering stack.

External actions requiring approval

1. Approve recording uploads or hosted transcription, any new software, and distribution of the resulting course material.

Why use this

1. A general lecture summary can hide the exact example that explains a difficult slide. Keeping page and recording coordinates together makes disputed notes easier to check.

2. The original visual material should remain readable so the learner can compare the explanation with the diagram rather than trust a detached paraphrase.

Why an agent / simpler alternative

Useful judgment

Distinguish a return to an earlier slide from a new topic and label uncertainty when repeated terms alone do not establish alignment.

Simpler alternative

Use a split-screen PDF viewer and timestamped bookmarks for a short, well-indexed lecture.

Unsuitable when

Recording rights are unclear or the notes will replace expert review of consequential content.

Expected deliverable and review checks

Proposed artifact

A review copy plus one ledger row per original page: transcript span, commentary status and unresolved issue.

Critical checks

1. Every page ID occurs once; missing pages stay explicitly uncovered.

2. Sample the mapped recording span as well as the rendered page; layout cannot verify meaning.

3. Compare original figures, equations and page order, then inspect dense pages for tiny text or clipped notes.

Missing output evidence

No completed output or independently observed run was inspected in this research.

First check — proposed, unexecuted

Status

proposed_unexecuted

Synthetic fixture

Invent three slides and a timestamped transcript that explains slide 3, returns to slide 1 and never discusses slide 2. Add a duplicate annotation ID and one out-of-window sentence.

Acceptance checks

1. Flag the duplicate before rendering and retain slide 2 as uncovered.

2. The return to slide 1 keeps its actual timestamp; exclude the out-of-window sentence.

3. A later authorized render must preserve all original page content and readable notes.

Stop conditions

1. Stop if matching source versions, rights or a reviewer for ambiguous passages are unavailable.

Failure signals and proposed responses

1. Signal

   A repeated term maps commentary to the wrong slide.

   Why it matters

   The note can teach a false association.

   Proposed response

   Compare nearby examples and time boundaries; leave the mapping unresolved if ambiguous.

2. Signal

   Two annotation rows share one page ID.

   Why it matters

   One explanation may silently replace another.

   Proposed response

   Reject the ledger before rendering and resolve the duplicate against the source sequence.

Effort and cost — unknown

Setup work

1. Align a small unit and settle the permitted recording window.

Ongoing review

1. The learner or lecturer checks difficult mappings and dense pages.

Unknowns

1. Unknown: transcription/model charges, rendering compatibility and correction time.

Limits

1. This proposed first check would assess an alignment contract; it does not establish comprehension or PDF fidelity.
