Bug-012- Skill-specific experience years are assigned without clear evidence or calculation trace.

Suggested bug / clarification

Summary:
Skill-specific experience years are assigned without clear evidence or calculation trace.

Module:
Resume Parsing → Skill Experience Extraction

Severity: Medium
Priority: Medium

Description:
The parsed resume output assigns specific experience durations to individual skills, such as Node.js = 6.7 years, Express.js = 6.7 years, MongoDB = 4.7 years, PHP CodeIgniter = 4.9 years, and Redux = 0.0 years. However, the resume does not explicitly provide these exact durations for each skill.

The output does not indicate whether the years are:

Explicitly extracted from the resume.
Inferred from employment duration.
Inferred from project duration.
Calculated from skill mentions across roles.
Assigned as zero when no duration is found.

Expected:
The system should either:

Extract skill-specific years only when supported by explicit resume evidence, or
Clearly identify inferred values and provide the source role/project or calculation basis.

Actual:
The system returns precise skill-specific years without an explanation of how those values were calculated.

Example:

{
"skill": "Redux",
"years": 0.0
}

The resume lists Redux as a skill, but does not provide a specific duration.
