v0.1.1 — Bug fixes, test refactor, improved examples

What changed since v0.1.0

Bug Fixes

• Silent data loss in _shorten_keys — timestamp and created_at both mapped to ts. When both existed in the same dict, aggressive mode silently dropped one value. Fixed with collision detection.
• URL corruption in CodeMinimizer — https://example.com inside string literals was stripped because the // comment regex had a broken single-char lookbehind. Replaced with a string-aware regex that matches quoted strings first.
• _shorten_dotted_keys crash on non-string keys — "." in 1 raised TypeError. Fixed with isinstance(k, str) guard.
• DiffMinimizer silently folded \ No newline at end of file — the backslash marker was treated as context and lost in large diffs. Fixed by adding "\\ " to significant prefixes.
• Markdown misdetected as diff — a --- horizontal rule plus any @@ mention triggered diff detection. Tightened to require diff --git header or --- followed by +++ .
• _sample(n=1) caused ZeroDivisionError — step = (len-1) / (n-1). Fixed with early-return guards.
• ALL CAPS words abbreviated with wrong case — IMPLEMENTATION became Impl instead of IMPL. Fixed with word.isupper() check.

Test Suite

Refactored 3 monolithic files (1000+ lines each) into 19 focused modules:

tests/
  unit/          # one file per minimizer
  adversarial/   # one file per concern (types, unicode, regex, contracts, mutation, concurrency, performance)
  real_world/    # tool output tests (pytest, cargo, go test, ruff, git, docker, build errors, pipelines)

New Makefile targets: make test-unit, make test-adversarial, make test-real-world

Examples

Replaced abstract examples with runnable, output-showing demos:

• examples/rag_pipeline.py — 3 realistic wiki docs, naive vs ptk context, per-query cost + monthly savings
• examples/langgraph_agent.py — simulated 3-step agent loop with token savings per step
• examples/log_triage.py — 400-line CI log → 19-line error triage (96.5% saved)

Other

• README: lead with before/after, real token counts, cost math
• uv-only CI: uv sync --locked --only-group <group> per job, built-in caching
• Dependabot: switched from pip to uv ecosystem (picks up uv.lock + [dependency-groups])
• SECURITY.md added
• CodeQL continue-on-error removed (repo is now public)
