feat(dataflow): DF3 URL stitcher with placeholder normalisation#6
Merged
Conversation
Implements match_route(graph, fetch_url, fetch_method, body_keys=None) →
(handler_qualname, confidence) | None.
Confidence rubric:
1.0 exact literal-segment match
0.9 placeholders normalised to same shape
(covers {id}, ${id}, :id, and pure-numeric segments)
+0.05 body-key overlap bonus when fetch body keys match handler params
(clamped at 0.95 / 1.0 ceilings)
0.5 prefix-only fuzzy match (last-resort)
Strips ?query and #fragment, normalises trailing slash, case-insensitive
method comparison. Tiebreaker: more specific path (more literal segments)
wins.
17 new tests covering exact match, placeholders (3 styles), method mismatch,
multi-method same path, specificity tiebreaker, body-key bonus, multiple
placeholders, trailing slash, query string, fragment, prefix fuzzy, case
sensitivity. Self-graph: 443 tests pass.

`codegraph serve` generated a pyvis HTML page per explored function and never pruned them. Long-lived projects could grow `.codegraph/explore/` to hundreds of MB. New module `codegraph/cache_prune.py` implements LRU eviction by mtime (oldest first). `codegraph clean --max-size-mb 50` (default) prunes until under the cap; `--all` wipes everything. `codegraph serve` runs the prune on startup and prints the current cache size as a dim line so users notice if it's still growing. v0.1.2 backlog item #6.
