bug: example/demo penalty (-2) still leaves examples at high confidence in top ranks

[aryamthecodebreaker]

What happened?

Example/demo paths are only penalized by 2 points (EXAMPLE_CODE_PENALTY), so they still land in the top ranks at high confidence on real implementation tasks.

Against expressjs/express (fresh remote fetch) with:

npx -y @aryam/fixmap@0.7.3 plan --repo https://github.com/expressjs/express \
  --issue "req.query is empty when using a custom query parser" --format json

Observed:

rank	path	score	confidence	note
1	lib/application.js	22	high	good (compileQueryParser)
2	lib/response.js	20	high	questionable for query parsing
3	examples/mvc/index.js	18	high	reason includes “example or demo code deprioritized”
4	lib/utils.js	18	high	also defines compileQueryParser
5	lib/request.js	16	high	actual request query surface
6–8	more examples/…	14–12	high/medium	same weak penalty

So the deprioritization fires (reason string present) but does not keep examples out of the agent’s top window. lib/request.js — the natural fix site for req.query — sits below an example.

Source: packages/core/src/rank.ts (EXAMPLE_CODE_PENALTY = 2, AUXILIARY_CODE_DIRS).

How can we reproduce it?

Run the express command above; confirm examples/ entries in the top 8 with high confidence despite the deprioritized reason.

What did you expect instead?

Examples should drop below first-party lib/ (or at least below high confidence) for implementation tasks unless the task text targets demos/examples. A −2 flat penalty is too weak when content overlap can add 10–20 points.
