Reduce repeated native completion guidance and preserve final replies (#15151)

## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Native agents receive task constraints and completion tools from
Paperclip.
> - Completion tools already define the procedure for reporting a
result.
> - Repeated procedure text adds instructions to each full task turn.
> - The final reply must still explain a blocker and link a saved
document.
> - This pull request removes repeated procedure text and keeps these
visible outcome requirements explicit.
> - A document receipt supplies the exact link, and stricter evals check
the persisted reply and browser navigation.

## Linked Issues or Issue Description

Refs: #14961. Related: #14948 and #15007.

**What happened?**

Native task envelopes repeat completion procedure text. A reduced
envelope needs explicit final-reply requirements. The `write_document`
receipt also lacks a canonical document link.

**Expected behavior**

Keep the completion tools as the source of procedure details. Require
one accepted completion result before the final reply. A blocked reply
must explain the reason, owner and unblock action. A document reply must
contain a working link to the saved document.

**Steps to reproduce**

1. Run the native assigned-skill document case and native blocker case.
2. Inspect the run-attributed provider final and its persisted comment.
3. Check the blocker explanation or open the final reply's document
link.

## What Changed

- Remove repeated completion procedure text from the native task
constraints and backend instructions.
- Keep explicit blocker and document-link requirements in full task
turns.
- Return a company/task-scoped `documentHref` from `write_document`.
Preserve the link in the idempotent mutation receipt.
- Repeat canonical links for this run's current saved revisions in
accepted completion feedback. Give blocked providers final-response
guidance for the cause, owner and unblock action.
- Keep internal document/comment anchors when Markdown issue links load
cached issue details.
- Add a manual six-cell comparison suite with strict source, build,
default-instruction and budget admission.
- Capture eighteen shared runnerd RPC projections and six direct
OpenCode HTTP projections across start, resume and continuation phases,
using scripted local transports and no provider execution.
- Apply v3 checks only to the manual instruction comparison; preserve v2
checks for the existing native completion suite. Check the actual
persisted blocker reason and exact saved-document link. Click the
rendered document link and check the original content marker in the
classic document card or the new document tab.
- Forward exact OpenCode finishing calls through the controller. Wait
for acceptance, keep accepted feedback and concrete rejection text, and
reject malformed responses. Preserve ordinary dynamic-tool response
handling.
- Settle the completion decision and tool response before mapping a
racing idle/error/abort event or handling explicit close/interruption.
Reject a concurrent finishing call before controller admission.
- Add a provider-free regression through real runnerd, the OpenCode
proxy and a fake provider. Reject the first completion, accept the
corrected report in the same turn, and propose one result.
- Keep all original verdicts unchanged. Treat replay under new checks as
separate diagnostics.

## Verification

- `pnpm -r typecheck` and `pnpm build` pass locally.
- Native document-authority tests pass, including company/run
authorization and idempotent replay.
- Native runtime-context, backend and measurement tests pass.
- Final-answer calibration, protocol scoring, source-admission and
catalog tests pass. Wrong reasons, absent links and wrong link targets
fail.
- `pnpm test:e2e:runner:typecheck` passes. Discovery lists exactly six
single-attempt local cells with the declared models.
- Exported `prepareNativeInstructionPreflight` then
`verifyNativeInstructionPreflight` pass on this clean committed source.
They build locally and make zero provider calls.
- Corrective live confirmation is incomplete. Source 3a7349d passed both
Claude and both Codex cases. OpenCode saved the correct document but
omitted its final link; its blocker case was canceled before paid
execution. Preserve this failure. The e171282 confirmation was stopped
during build after fresh review found a completion-settlement race; it
executed zero providers. Source c3e0cb303 fixes that race. Two affected
OpenCode cases await fresh review and one bounded confirmation; earlier
results remain attributed to their original source.
- OpenCode proxy parsing, driver, factory and input tests: 81 pass
across retained focused runs, including six settlement races.
Evaluator/scoring/admission checks: 122 pass. The real proxy regression
passes. Fresh local prepare then verify passes with 18 shared and 6
direct scripted captures, fresh SDK/Rust builds and zero providers.
- The full local suite recorded two failures: a webhook timeout and a
Git-scan load count mismatch. Both files pass in isolation with
unchanged assertions/time budgets; preserve the original failure log.
Fresh c3e0cb303 CI and review are pending. This PR remains draft.

## Risks

- Final-answer wording can vary by provider. The checks cover the
declared release-access blocker and saved document fixture, not general
answer quality.
- A single trial does not establish general equivalence, cause, speed,
cost or live resume behavior.
- `documentHref` is an additive receipt field. It points to the current
saved document, not an immutable historical revision. Replaying an older
receipt does not fabricate a new link.
- The correction adds four production paths for document receipts,
accepted completion feedback and UI navigation, plus four OpenCode
controller/proxy paths, beyond the original three instruction paths.
Completion rejection must remain repairable; the production-boundary
regression covers it.
- Preserve the frozen comparison context for live measurement. A
merge-tree check against current master is clean. Do not relabel earlier
live results as results from a later source tree.

## Model Used

- OpenAI Codex, GPT-6 family. The exact serving model ID and context
window are unavailable in this session. Capabilities used: reasoning,
code editing, shell execution, test authoring and evidence review.

+# Native completion constraint consolidation
+
+Date: 2026-10-03. Roadmap item: 2.3. Status: implementation and provider-free calibration; live behavior is unqualified.
+
+## Change and comparison axis
+
+The first slice replaces the repeated final-response procedure in native task constraints with a short requirement to obtain an accepted `paperclip_finish` or `paperclip_block` result and follow that tool's reporting instructions. It removes the extra completion sentence in the Codex/runnerd and direct OpenCode backends. The existing finish/block tool descriptions still own rejection, retry, approval, link/action, explicit wait, and final-response behavior.
+
+The production comparison axis is exactly these three files:
+
+- `packages/paperclip-runner/src/backends/runtime-context.ts`
+- `packages/paperclip-runner/src/backends/codex-native-backend.ts`
+- `packages/paperclip-runner/src/backends/opencode-native-backend.ts`
+
+Both variants start from master `2a8a99e4a5f69aa803b3f10b982f583e75a87042`. The baseline retains those three original files. The candidate changes only those three production files. All fixture, grader, admission, test and documentation repairs must be common to both variants. The fixed execution prompt, production AGENTS bundle, completion tool descriptions/schemas, operational skills, hiring, connections and delivery guidance stay identical. The prior #14961 trial measured a different change and cannot qualify this one.
+
+## Provider-free measurement
+
+`src/backends/native-instruction-measurement.test.ts` in the Runner package captures actual `thread/start`, `thread/resume` and `turn/start` parameters from the real runnerd facade with a scripted transport. It captures native Codex, ACPX Claude and OpenCode for input v4 and v5: eighteen receipts per variant. Every receipt records exact UTF-8 bytes, character counts and hashes of the instruction string, fixture tool schemas, turn input and their full projection. It checks finish/block descriptions, document/file rules, approval mode and identical start/resume tools and instructions. The fixture uses the actual production AGENTS file and a fixed projection of the core semantic catalog plus the reserved completion tools.
+
+Run from `packages/paperclip-runner`:
+
+```sh
+PAPERCLIP_NATIVE_INSTRUCTION_REPORT=/absolute/path/measurement.json pnpm exec vitest run src/backends/native-instruction-measurement.test.ts
+```
+
+The receipt declares its source SHA, source file hashes, fixture hash and dirty state. A dirty overlay can aid diagnosis but is rejected for live admission. Temporary workspace paths are normalized to a fixed path for comparison. This is the complete declared Paperclip projection at that boundary, not the production server's full granted catalog or a capture of provider-owned stock prompts. Token counts, billing, provider preprocessing and cognitive consumption remain unknown. The capture distinguishes a resumed full task from the compact user-follow-up continuation envelope. Input v5 sends only new events and contract references for that continuation; its projection must remain identical between variants. Input v4 still wraps the compact message in a task envelope. Scripted resume and continuation capture do not qualify live resume behavior.
+
+## Bounded live comparison
+
+The explicit-only Product E2E suite is `native-instruction-consolidation`. Discovery requires no credentials:
+
+```sh
+pnpm test:e2e:runner -- --list --suite native-instruction-consolidation
+```
+
+Each source variant declares these original tasks on the same local native profiles:
+
+| Profile | Model | Tasks |
+| --- | --- | --- |
+| Codex | `gpt-5.6-sol` | assigned-skill document completion; whole-task blocker |
+| ACPX Claude | `claude-sonnet-5` | assigned-skill document completion; whole-task blocker |
+| OpenCode | `openrouter/deepseek/deepseek-v4-flash-0731` | assigned-skill document completion; whole-task blocker |
+
+Six cells per variant means twelve actual runs for the pair, each with one attempt. Use exact IDs with parallelism one and no automatic retry. Each cell uses the original task deadline and 1,000-cent company and agent hard stops. These budgets bound recorded Paperclip spend; they do not guarantee final provider invoice amounts. Do not run providers until the human authorizes the live scope. Stop to inspect a usable behavior failure; do not reroll it to obtain a pass.
+
+The source gate requires clean committed sources, the declared base ancestry, one complete known source variant, no unrelated paths, the current fixture digest and all eighteen provider-free capture receipts. It rejects missing, duplicated, dirty, stale or paid capture evidence. It verifies the requested immutable source SHA when supplied. A hosted shallow checkout may fetch its exact immutable SHA from the public repository at bounded depths 8, 32 and 128, without provider keys or Git credentials. It verifies exact HEAD after each fetch. The original base-ancestry and changed-path checks must then pass. No immediate-parent substitute is used. The only admitted untracked files are the exact same-run build archive and checksum, after the existing strict hydration verifier checks them.
+
+Admission rebuilds the TypeScript SDK from the current source with a credential-free environment and hashes the complete SDK outputs. Locally it also builds the native runner; hosted execution binds the selected native runner bytes to the verified same-run archive and records that local Rust calibration was not executed there. Preparation and verification preserve the source tree, fixture digest, metadata, build log/output hashes and selected native binary provenance. A mismatched or missing build fails before provider execution.
+
+The human authorized the bounded twelve-run pair on 2026-10-03. This does not authorize retries, broader paid scope, a merge or separate derived-report publication.
+
+The suite uses the original assigned-skill durable-document oracle and strict native completion grading. It retains named call-ID joins, acceptance/termination, final-response order, provider-final persistence, exact blocker owner/action/scope, workspace and issue/agent side effects, default instructions and budget evidence. Unknown or absent evidence cannot pass. No relaxed source-read matcher or provider-call join is introduced.
+
+## Decision and evidence
+
+Freeze both source refs, the common definition hash, models/profiles, permissions, default instructions, input construction, deadlines, budgets and compiled source identity before admission. Preserve every attempt, original grade, failure and usage receipt. Compare all six exact pairs and retained content; report new failures, new passes, unchanged failures, unchanged passes and uncomparable pairs separately. A passing total does not conceal a lost document, incomplete blocker report, extra work or a missing final response.
+
+The reduction remains unqualified until the paired live evidence exists. Passing deterministic checks proves transport/catalog and control-plane behavior under the tested scripted inputs. A single live pair per cell gives bounded evidence, not general equivalence, causation, cost/speed trends, general coding quality, or live continuation coverage. Approval feedback and yielded continuation need their own retained cases before making broader claims. If any behavior worsens, hold this slice and inspect the original evidence before changing source or expanding paid scope.

+# Native completion final-answer correction
+
+The completion constraint reduction remains held until the corrected source has live evidence for final-answer quality. Keep the original candidate, historical source and all original grades immutable.
+
+The correction keeps the shortened completion procedure while explicitly requiring a blocker explanation, owner and unblock action in the final reply. The existing document guidance now requires a canonical clickable document link. `write_document` returns a company/task-scoped `documentHref` in its idempotent receipt, derived in the document transaction from the saved key and actual task identity. No completion tool schema/description, fixed prompt, skill, permission or budget policy changes. The accepted completion feedback repeats canonical links only for this run's still-current saved document revisions, reconstructed from company/task-scoped database state rather than supplied URLs. Blocker feedback asks for the cause, owner and unblock action instead of describing completed work. Internal Markdown links retain their query and document/comment anchor when cached issue details resolve. These receipt, feedback and UI repairs add four production paths beyond the original three-file instruction reduction.
+
+Only the manual instruction comparison uses the v3 final-answer observation. The existing `native-completion` suite retains its v2 verdict checks and does not acquire the browser-navigation requirement. A calibration demonstrates the same retained input can pass v2 and fail v3; original report files are never rewritten. The harness definition digest changes truthfully for future invocations. Its additional checks read only the actual run-attributed persisted provider final. A blocker label and action do not substitute for an explicit missing-access explanation. Document links must identify the exact task and one revisioned document at the instance origin; wrong origin, task, document, query, credentials or absent evidence fail. Exact call-ID joins, acceptance/termination, ordering, side-effect and budget checks remain enforced.
+
+After saving the strict native snapshot, each completion cell clicks the rendered final-reply link in the browser. It must open the canonical saved document and show the original content marker in exactly one visible classic document card or document-specific side-panel tab. The navigation check follows the actual configured UI instead of requiring a classic-only element. Retain the navigation receipt and screenshot independently; a valid-looking Markdown URL alone does not qualify navigation.
+
+Calibrate with correct paraphrases and plausible wrong answers, including the action-only omission. Replay the retained observations only as labeled additional diagnostics; never overwrite or regrade the original results. Provider-free measurement v2 captures eighteen shared runnerd RPC projections plus six direct OpenCode HTTP projections across v4/v5 start, resume and continuation. The latter exercises the concrete OpenCode backend using a local fake server. Both boundaries measure Paperclip-supplied payloads, not provider stock prompts or model cognition. No synthetic receipt qualifies live model behavior.
+
+The human's paid-run authorization and subsequent request to fix the omission support one bounded corrective confirmation: the six exact `native-instruction-consolidation` candidate cells, one attempt each, no automatic retries, native Codex `gpt-5.6-sol`, ACPX Claude `claude-sonnet-5`, and OpenCode `openrouter/deepseek/deepseek-v4-flash-0731`, original local deadlines, and 1,000-cent company/agent hard stops. Each production correction must have a new immutable source/definition admission before another bounded confirmation. Preserve stopped campaigns, failed cells and canceled-before-provider cells separately. Never reroll an unchanged frozen failure. No new baseline provider run, broader campaign or merge is part of this correction. Stop and inspect a usable behavior failure.
+
+Report exact source, definition/grader hashes, six outcomes, retained visible replies and document targets, actual run count, cleanup and billing coverage. Passing a single trial does not prove general equivalence, cause, live resume behavior, coding quality, speed or cost trends.
+
+The receipt-only correction at `be604fcbf81ff238ee38774ff6e644bf0d84eb2d` failed its first Claude document cell; five remaining jobs were canceled before paid execution. The next correction at `3a7349ddc60142283c394121882288f2db07b215` passed both Claude and both Codex cases, but OpenCode again omitted the document link; its blocker job was canceled with the paid step skipped. Preserve both genuine failures and all canceled jobs. Browser navigation was not reached in either missing-link failure.
+
+OpenCode's inner driver admitted the finishing report locally without invoking the controller feedback handler. Its proxy also discarded the controller response envelope, including the success flag. The correction forwards the exact terminal call ID, thread, turn, tool and structured result through the existing controller request channel. It waits for the controller before committing the inner result, preserves accepted response text and concrete rejection reasons, and rejects malformed acceptance or a turn that ended during feedback. Dynamic-tool unwrapping stays unchanged. A provider-free test crosses the real runnerd, proxy and fake OpenCode boundary: the first completion is rejected, the provider corrects it in the same turn, the second receives the exact final-response feedback, and only one semantic result is proposed.
+
+This correction changes four additional OpenCode-only production paths. The shared instruction, server receipt/feedback and UI bytes remain identical to 3a7349d. Admit the new source and measure all scripted boundaries again. Confirm only the two affected OpenCode live cases on the new immutable source, one attempt each with the original model, deadlines and budget stops. Keep the four passing Claude/Codex observations explicitly attributed to 3a7349d, backed by the exact provider-path delta and final-head CI. Do not relabel them as live runs on the new head. No new baseline or unchanged-source paid retry is included.
+
+The e171282 confirmation campaign 37257534042 was stopped during build after fresh review identified a controller/inner-session acceptance race. No paid step started and no provider was executed. Provider-free regression reproduces accepted feedback losing its result when idle/error arrives in flight. Completion settlement now holds terminal mapping, explicit interruption and close until the bound decision and tool result finish, and refuses a concurrent terminal submission before invoking the controller. Raw SSE frames remain retained at receipt; normalized terminal settlement follows the finishing decision. Confirm the same two OpenCode cases only on the newly admitted immutable source; preserve e171282's completed failing review and zero-provider campaign.
+
+Fresh c3e0cb303 review identified a real serial-input dependency: an interrupt waits for completion while its controller response queues behind the interrupt. No paid campaign was admitted on this source. The proxy now handles only bound response frames outside the serial command queue; commands retain their order and bootstrap failure gates. EOF rejects existing controller waiters and prevents new unanswered requests, then drains the command queue and closes. A real production-bundled proxy, verified local native launcher and fake OpenCode MCP/SSE server reproduce the deadlock before the fix and verify accepted feedback reaches the provider, interruption completes, exactly one result is proposed and EOF exits. A second EOF-without-feedback case proposes no result. This is zero-provider proxy coverage; the real runnerd boundary remains separately covered. Fixture setup and macOS launcher failures are retained, not relabeled as behavioral failures.
+
+The exact 267aeb3 source passed fresh 5/5 review, but confirmation campaign 37259746983 stopped before provider execution. Its document job entered the harness step, then failed source ancestry hydration before result creation: the fixed eight-commit fetch did not contain the required 2a8a99 base. The remaining blocker cell was canceled. The source was not behaviorally evaluated, and no graded result or cell artifact exists; retain the original failed job log and separate zero-provider receipt.
+
+Hosted hydration now fetches only the immutable public source at bounded depths 8, 32 and 128. It verifies exact HEAD after every fetch and still requires real base ancestry. A missing or unrelated ancestor, changed HEAD, local checkout or non-shallow checkout does not receive a substitute proof. A real twelve-commit shallow-clone regression fails before the change and passes afterward. Production, fixture prompts, model/default/budget policy and behavioral grading bytes stay unchanged from 267aeb3. Admit the new setup source and confirm the same two OpenCode cases once; no provider run or original failure is retried.

 The independent, explicit-only `native-completion` suite qualifies native finish/block descriptions on unchanged master defaults. It preserves the original assigned-skill document journey and pairs it with whole-task blocking across three native profiles, with enforced single attempts. See [NATIVE-COMPLETION.md](NATIVE-COMPLETION.md) for admission, provenance and limits.
 
+The separate, explicit-only `native-instruction-consolidation` suite reuses those original tasks and strict graders to compare completion constraints on the production defaults at `2a8a99e4a5f69aa803b3f10b982f583e75a87042`. It declares six local cells: document completion and whole-task blocking on native Codex, ACPX Claude, and OpenCode. Each cell allows one attempt and applies a 1,000-cent company and agent budget hard stop. Its source gate rejects dirty, mixed, unknown, or unrelated source changes before credentials load. A provider-free fixture captures the complete Paperclip instruction/tool/message projection at the scripted runnerd RPC boundary on start, full-task resume and compact user-follow-up continuation for native input v4 and v5. That capture measures bytes; it does not measure vendor-owned prompts, tokens, billing, or model behavior. See the [comparison plan](../../doc/plans/2026-10-03-native-completion-consolidation.md) for exact scope and live qualification limits. Existing `native-completion` results do not qualify this new reduction.
+
+The corrected source variants add explicit blocker explanations and canonical document citations. Accepted feedback repeats links only for this run's current saved revisions, and Markdown navigation preserves document anchors after issue details load. Observation v3 independently requires the persisted provider final to explain missing release/deployment access and, for completion, link this task's one revisioned document on the same origin. A correct structured blocker, an unblock action alone, or an unbound/foreign document URL cannot pass. These stricter checks and browser navigation apply only to the manual instruction comparison; the existing `native-completion` suite keeps v2 checks. Task prompts and the durable-output oracle remain unchanged. Admission now requires eighteen shared runnerd RPC captures and six direct OpenCode HTTP captures using a local fake server, all provider-free. Replay of retained v2 evidence is a separate diagnostic, never a replacement for its original verdict. See the [answer correction](../../doc/plans/2026-10-04-native-completion-answer-fix.md).

 `context-integrity` is an explicit-only local suite with two bounded cases across
 ten listed legacy/native profiles (20 cells). Six cells are pending-prerequisite
 profiles and are listed for discovery but rejected before provider credentials are
