Repair AWS Lambda Event Source Filter Alias Mismatch
Example session with this skill installed
Case: A DynamoDB stream event is present but no Lambda consumer invokes.
Provided: Lambda event source mappings and deployed alias version inventories (illustrative, partial). Potential exception: filter criteria update was applied only to an inactive mapping revision. Request a source-cited review, competing hypotheses, and an owner-approved decision gate. Do not execute changes or assert unsupplied facts.

Repair AWS Lambda Event Source Filter Alias Mismatch — SYNTHETIC EVIDENCE-LIMITED REVIEW
Case received
A DynamoDB stream event is present but no Lambda consumer invokes.
Evidence register
- S1: Lambda event source mappings and deployed alias version inventories — PARTIAL / UNVERIFIED.
- S2: approved operating baseline / documented policy — NOT PROVIDED; REQUIRED TO VERIFY.
- S3: timestamped revision or change record — NOT PROVIDED; REQUIRED TO VERIFY.
- S4: accountable reviewer and approval evidence — NOT PROVIDED; REQUIRED TO VERIFY.
Investigation checks
- Establish the identity, timestamp basis and revision lineage of Lambda event source mappings and deployed alias version inventories; document missing or contradictory records. — PENDING CORROBORATION.
- Reconstruct the event sequence surrounding filter criteria update was applied only to an inactive mapping revision, citing exact record identifiers and independent checks. — PENDING CORROBORATION.
- Compare the evidence with the approved baseline; test the competing explanations for: A DynamoDB stream event is present but no Lambda consumer invokes. — PENDING CORROBORATION.
- Draft a non-executing, owner-approved validation sequence and rejection criteria for event mapping alias crosswalk and delivery regression tests. — PENDING CORROBORATION.
Deliverables
- time-aligned evidence index for Lambda event source mappings and deployed alias version inventories: DRAFT / INCOMPLETE until inputs are validated.
- exceptions and alternative hypotheses for filter criteria update was applied only to an inactive mapping revision: DRAFT / INCOMPLETE until inputs are validated.
- approval-gated event mapping alias crosswalk and delivery regression tests and verification criteria: DRAFT / INCOMPLETE until inputs are validated.

What to provide
- Lambda event source mappings and deployed alias version inventories
- approved operating baseline / documented policy
- timestamped revision or change record
- accountable reviewer and approval evidence
Deliverables
- time-aligned evidence index for Lambda event source mappings and deployed alias version inventories.
- exceptions and alternative hypotheses for filter criteria update was applied only to an inactive mapping revision.
- approval-gated event mapping alias crosswalk and delivery regression tests and verification criteria.
Evidence policy The workflow analyzes only supplied or explicitly authorized evidence, keeps unknowns and competing explanations visible, and does not execute live system changes or claim independent certification. An authorized owner must approve operational decisions.

No live validation or direct platform access is asserted. Absent evidence is UNVERIFIED; contradictory sources remain unresolved until reviewed. Only authorized owners may approve real-world actions.
