# Hope Sweep

Apply proven maintenance to operating code and directly supporting tests,
configuration, build logic, documentation, examples, and assets. Read
`../write/references/writing-standard.md` for user-facing language.

## Invocation and scope

Require explicit namespaced invocation. An ordinary cleanup request or a
follow-up such as “do that” uses the ordinary workflow. If selected implicitly,
continue that request without activating Sweep.

Use the named repository, or the current one, and the whole repository unless
the person narrows it. Record the revision and working-tree state; preserve
unrelated edits and project instructions. Invocation authorizes reversible
local edits in this scope, not commits, pushes, pull requests, or merges.

## Prove and apply cleanup

Trace entry points, active consumers, runtime registration, configuration, and
build boundaries. Running code and configuration establish current behavior
when supporting material disagrees.

Remove dead code, duplication, needless branches or wrappers, misplaced
abstractions, and repeated work. Share logic only when behavior, ownership,
and reasons to change match. Optimize only for a plausible workload with a
concrete benefit.

Before removal, check public and external consumers, dynamic lookup,
reflection, string-based registration, generated sources, and package boundaries.
A missing text reference alone does not prove safety. Remove dedicated tests,
documentation, generation, configuration, and assets with their obsolete
consumer; retain support for remaining paths.

Apply small coherent batches. Leave bugs, public-contract or behavior changes,
product and compatibility decisions, migrations, dependency changes, and
uncertain removals outside Sweep. Do not turn those signals into unsolicited
findings or follow-up tasks.

## Verify and finish

Verify affected consumers with the narrowest useful tests, checks, builds, or
runtime observations, plus required project checks. Add tests only when needed
to protect the refactor. Correct or revert regressions Sweep introduced; do not
repair pre-existing failures or widen scope during verification.

Finish when the supported candidates are resolved and one pass over the changed
scope finds no new proven cleanup. Report the cleanup, supporting material
changed with it, and checks or verification gaps. If no proven cleanup exists,
say so. Keep unrelated signals out of the report.
