Rename live PolicyBench references and paper-rendering names to Microcosm while preserving frozen records and identifiers.

What changed

• Updated live documentation, app labels, paper source, comments, and generated-report wording.
• Renamed paper-rendering properties and constants, retaining their old names as compatibility aliases.

Left as is

• H: 673 mentions in historical run paths, frozen results, published paper artifacts, audit records, and text that reproduces frozen artifacts.
• R: 46 mentions in published dataset identifiers and recorded provenance values.
• Compatibility aliases: 10 mentions (eight alias names plus two group marker comments) preserve the old Python names.
• D and mapping line: none.

Compat aliases

Remove after the next release: POPULACE_PEOPLE, POPULACE_HOUSEHOLDS, POPULACE_ELIGIBLE_HOUSEHOLDS, and PaperResults.populace_people_fmt, populace_households_fmt, populace_eligible_households_fmt, populace_eligible_pct_fmt, and populace_excluded_pct_fmt.

Two group comments mark them, one above each block: # compat: populace alias, remove after next release (the three lines below) at policybench/paper_results.py:767 and (the five lines below) at :1562. A removal grep finds those two hits.

Tests

• git diff --check: passed.

• python -m compileall -q on the changed Python files: passed.

• pytest -q -n 4: could not run because pytest-xdist is not installed. A serial python -m pytest -q encountered a missing hypothesis dependency during collection and was interrupted.

• bun test tests in app: 84 passed; 11 failed to load because dependencies including React and fast-check and generated src/data-summary.json are missing. bun install --frozen-lockfile initially failed on temp-directory permissions; a retry with a writable temporary directory stalled and was interrupted.

• CI at 315f58f: lint, test, app, paper and Vercel all pass. Lint first failed at 0ae0410 (ruff E501 on seven alias lines that carried a trailing marker); commit 315f58f moves each marker above its group, and the module's AST is unchanged.

Review

• Sol (GPT-6.1) approved 0ae0410 with no blocking findings.
• An Opus 5.5 reviewer approved the comment-only delta at 315f58f with no blocking findings; it asked for these corrected counts.

Unsure

• scripts/freeze_snapshot.py:1828 and scripts/freeze_snapshot.py:1926: retained these prose templates as H because they reproduce frozen snapshot artifacts; a reviewer may wish to confirm whether future snapshot wording should change.
