Dotta 7bb6cebeae feat(runner): normalize ACPX provider events (#12416)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - The Rust runner now admits ACPX sidecar frames only after transport,
scope, and payload validation
> - Valid payloads still contain provider-native runtime event shapes
> - Provider-native shapes must not cross the PRP boundary or diverge
from direct Codex task activity
> - This pull request maps the display-safe runtime subset into existing
provider-neutral event families
> - Stateful semantic-result, terminal, and reasoning-deduplication
behavior remains reserved for the later provider adapter
> - The benefit is a reviewable normalization boundary without selecting
ACPX in production

## What Changed

- Normalize validated ACPX text, reasoning, plan, status, tool, notice,
and error updates into existing PRP activity families.
- Keep reasoning contents private while preserving a reasoning activity
boundary.
- Map plan entries, usage, review-mode status, and tool lifecycle into
bounded canonical payloads.
- Generate one shared ACPX sidecar event/classification contract for
TypeScript and Rust, with ASCII-only classification parity and bounded
kind/title fields.
- Preserve authoritative tool-call identity and classification even when
the aggregate native event exceeds the generic frame budget.
- Resolve display-only tool targets within the workspace under the
provider host's path semantics; reject raw, unmarked, absolute,
parent-traversing, URL-shaped, and unsafe drive-shaped values.
- Redact and digest retained tool output with the existing durable
policy.
- Ignore provider inventory status updates that have no user-facing
activity.
- Leave semantic results and `done` updates to the stateful adapter so
durable receipts and terminal events are not duplicated.
- Add cross-language and Rust coverage for every mapping family,
classifier parity, privacy, unsafe paths, redaction, bounded
titles/kinds, and oversized tool-call preservation.
- Document the normalization and display-path authorization boundary.
- Do not change dependencies, lockfiles, workflows, runnerd selection,
server behavior, UI, or migrations.

## Verification

- Replay base: `fe2ddfad2b5cb604b3244492257db0e6aec11d47` (`master`
after #12415 merged).
- Exact replay head: `b7f5588bf6e8e0f946ffa8869a3204c344808418`.
- Stable patch ID: `fda62c7c20afc5ef9c75d07f163a466db82efabd`, identical
to the prepared six-commit delta plus the focused oversized-tool-call
review fix.
- The exact delta is 14 files, 1,714 additions, and 60 deletions, all in
`packages/paperclip-runner`; it contains no lockfile, workflow, server,
UI, or migration change.
- Focused protocol-generation, TypeScript sidecar, Rust normalization,
package, repository, security, and Greptile checks: **PASSED** on the
replayed exact head. Full CI run `33361437835` completed 23/23 jobs
successfully, Greptile is exact-head 5/5, all security checks pass, and
no review threads remain unresolved.
- No local test result is claimed. GitHub Actions is the authoritative
verification environment for this replayed revision.

## Risks

- This code controls what provider activity is retained and displayed,
so malformed native values must not bypass the earlier decoder.
- The function contract requires an already scope-checked and
payload-validated runtime event; the future adapter must preserve that
order.
- Tool classification and identity are security-relevant authorization
inputs and remain explicit even when optional aggregate display data is
dropped for bounds.
- Repeated reasoning chunks require stateful suppression. This mapper
exposes a privacy-safe start boundary and the later adapter owns
per-turn deduplication.
- Semantic results and terminal authority intentionally produce no
activity here; the later adapter must commit them through the durable
operational paths.
- The package exports new generated and Rust normalization surfaces, but
no production path invokes them in this pull request.

## Model Used

- OpenAI Codex with GPT-5.6, agentic reasoning, tool use, and code
execution.
