+# Repair/save native-v4 evidence
+
+Three root-operated native workflows passed on GUI B183/source33c6d83: missing include repair, duplicate alias repair, and v1 journal recovery. Apply kept repaired bytes unsaved; Close prompted; Cancel retained the work; explicit Save was followed by exact full-model/source equality. See the [native report](../../../release-text-repair-save-native-v4-20260911.md) for chronology and scope, and the [correction gates](../repair-save-correction/README.md) for source/build provenance.
+
+`preparation-README.md` is the original pre-launch document, preserved exactly. Its pending/no-launch wording describes preparation, not the completed trial. `helper.py`, `fixture-manifest.json` and all 64 fixture files are retained. Under `trial/` are seven disk checkpoints, three real saved-oracle receipts/log pairs, 20 original screenshot JPEG/metadata pairs, and launch/admission/binary/readback/empty process logs.
+
+All originals copied here are exact bytes. `manifest.json` is the complete payload whitelist, including original paths; `readback.json` records original/archive and fixture/checkpoint/equality checks. Omitted final trial model directories were byte-identical to retained fixtures/checkpoints, recorded in `excluded-duplicates.json`. No binaries, profile or temporary/cache contents are included. GUI/DLL identity remains in before/after receipts.
+
+Root observed normal close and subsequent window/PID absence. The helper records caller-observed absence, not an independently obtained numeric process exit code. Empty stdout/stderr and unchanged GUI/DLL are preserved. The window was 1442 by 932; this was not a minimum-size or full navigation retest, and no package/release/Linux result is implied.
+
+Run `python verify_archive.py` for read-only hash, whitelist, fixture, screenshot, checkpoint and saved-oracle receipt verification; it does not launch a binary or rerun an oracle. Python 3 standard library only.

+# Restore safe water pressure
+
+This source-7 project follows one engineering question: after a pressure alarm, can the control room restore service remotely, or must a technician repair a valve? It connects the operational need to an explicitly chosen coordination-service boundary. Allow about 25 minutes for the walkthrough.
+
+Copy the whole `examples/release1` folder to your working location, then open the copied `project.arcadia` in Arcadia Studio. Keep the folder together: the entry includes 29 modules, and the evidence link is relative to it. If you instead use Save As to a new folder, it copies model source files only: also copy `evidence/` beside the new entry and keep this README available. Save As does not copy external artifact targets. Existing older examples remain useful migration exercises.
+
+The numbers, guards and states describe an illustrative design. The model does not simulate hydraulics, execute a control algorithm, or establish the safety of an actual water network.
+
+## 1. Start with responsibility, not equipment
+
+Open saved view **1 · OA responsibility and repair traffic**. The **Control room** assesses the alarm, resets the valve and confirms pressure. The **Field technician** performs field repair. The parent activity **Restore safe pressure** groups these leaf activities; responsibility is allocated to the leaves.
+
+Inspect **Technician service conversation** (`oa_contact`). This unoriented CommunicationMean connects operational participants. **Request field repair** and **Report repair result** are Interactions between their allocated activities. Each Interaction is explicitly allocated to the communication mean. No OA port or implementation component has been introduced.
+
+Inspect the **Valve repair** exchange item and its `pressure` parameter. The parameter has direction InOut, Value storage, multiplicity 1..1, and a real-valued type bounded from 0 to 600 with unit text `kPa`. The unit documents the contract; no conversion is inferred.
+
+## 2. Follow the alternative and its reusable procedure
+
+Open process **Handle a pressure alarm** (`oa_response`) in the behavior workspace. Its first step references **Assess an alarm procedure** (`oa_assessment_procedure`), whose Action uses the assessment activity and whose ChainInvolvement supports **Assess an alarm**. Follow that reference to the Choice in the main process. The guarded branch allows an authorized remote reset; the `else` branch references **Field repair procedure** (`oa_field_procedure`). Both paths merge before confirmation. The explicit SequenceLinks define flow; the list of steps alone does not imply those branches.
+
+Open the referenced procedure. It contains request exchange, repair action, then report exchange. The parent process reuses that procedure by identity. It does not copy its actions. The main process contributes to the restoration capability.
+
+Open scenario **Repair request and measured reply** (`oa_conversation`). The Control room calls the technician using the communication mean, supplying `420.0`. The technician's correlated Reply returns `320.0` on the reversed participant pair. The reply points to the actual Call. The enclosing scenario (`oa_full_scenario`) reuses this conversation with two explicit lifeline bindings.
+
+The mission **Maintain safe water supply** links to the restoration capability, which includes the assessment capability. The repair conversation has the restoration context: it begins after assessment and coordinates repair. The assessment procedure supplies the separate assessment behavior support.
+
+## 3. Examine the explicit SA engineering decisions
+
+Open **2 · SA service boundary and functions**. The chosen System is **Pressure coordination service**; the technician remains outside as a SystemActor. OA activities have traced SA functions. The communication mean has a traced SA BoundaryExchange (`sa_contact`), with two explicitly chosen Standard component ports. The two Interactions have traced FunctionalExchanges with directional function ports.
+
+Inspect **Valve repair service** (`sa_repair_interface`), its synchronous Operation acceptance, and the client Requires / provider Provides links. Four PortAllocations connect the function ports to their component ports; two ExchangeAllocations connect functional traffic to the boundary exchange. These are explicit contract refinements. An operational channel cannot choose the technical interface or ports on the engineer's behalf.
+
+The generator performs the real OA→SA transition. `transition-before.json` is the OA model plus the two intentionally named SA participants. `transition-request.json` contains their explicit mappings and both component-port Create decisions. It deliberately leaves the operational ExchangeAllocations out of this first transition: those allocations require the later reviewed SA interface and port refinements. Omitting these allocations is explicit, not silently guessed.
+
+For a fresh transition exercise, import `transition-before.json`, select the OA content, map Control room to the existing System and Field technician to the existing SystemActor, and review both communication endpoint ports. The supplied request is the exact programmatic counterpart. The generated final project then adds the interface/port allocations, views, evidence and one unfinished function. Fresh transition UUIDs are normalized by the generator for stable published files, so an interactive replay is semantically comparable rather than byte-identical to `model.json`.
+
+## 4. Compare views without changing the architecture
+
+Switch between **2 · SA service boundary and functions** and **3 · SA service conversation only**. They place the same semantic identities. The focused view uses the participant exchange category, an explicitly empty work-category selection, and NameAndItems labels. It shows the boundary conversation and hides functional traffic. The underlying exchanges and their port positions remain unchanged.
+
+Open View properties to inspect the selections. Clearing a filter does not delete a relation. The category is an engineering collection of existing exchanges; it is not a replacement exchange. **4 · SA mission and included capability** supplies a separate goal view.
+
+Open **5 · SA pressure supervision** in the state workspace. Follow the initial state to monitoring, the typed high-pressure Change event into waiting, and the guarded return. Waiting has an Entry action linked to the assessment function. This is an event/action relationship, not free prose embedded in a transition label.
+
+## 5. Investigate the deliberate warning
+
+Model checks should report exactly one warning: `work_without_behavior_context` on **Audit pressure thresholds** (`sa_audit_thresholds`). It has a responsible System but no process/chain or scenario use. `expected-diagnostics.json` records the expected located issue.
+
+Decide whether threshold auditing belongs in the response process, in a separate maintenance behavior, or outside the intended model. Add the appropriate behavior use or remove the explicitly out-of-scope function. Merely hiding it in a view would not resolve the coverage question. The supplied model intentionally leaves this decision open.
+
+## 6. Make one reviewed change and inspect its source
+
+1. In OA, rename **Confirm safe pressure** (`oa_confirm`) to **Confirm stable pressure** and Apply the edit.
+2. Open semantic OA→SA review for that activity and its existing function counterpart (`sa_confirm`). Review the Header Name facet and choose Take source. Preview, then Apply the reviewed change.
+3. Confirm that the SA function name changed while the deliberately different System name remains **Pressure coordination service**.
+4. In Source, inspect `sa/functions/function_sa_restore_work.arcadia` and `traceability.arcadia`. The counterpart name and review history change. Unrelated modules retain their text. Use Undo/Redo in this editing session to inspect the reviewed transaction; then Save and reopen to check persistence. Undo history is session-local; reopening restores the saved model, not the previous undo stack.
+
+The integration oracle executes this exact semantic review and source update. It separately proves that changing the request Interaction to target a Control-room-owned activity violates the communication allocation's performer pairing: command and source-update paths reject the invalid candidate together.
+
+## Source, service and reproducibility
+
+| File or folder | Purpose |
+|---|---|
+| `project.arcadia` | Openable source-7 entry with all module includes |
+| `oa/`, `sa/` | Participants, work, data, capabilities and reusable behavior |
+| `views/` | Five saved views; filters and placements are presentation state |
+| `traceability.arcadia` | OA↔SA correspondence and review history |
+| `model.json` | Current schema-7 interchange of the final accepted model |
+| `transition-before.json`, `transition-request.json` | Explicit first-transition replay inputs |
+| `evidence/repair-check.md` | Local teaching evidence linked from the SA conversation |
+| `model.rs` | Deterministic lesson builder shared by generator and tests |
+
+The REST routes are documented in [the API reference](../../docs/api.rst). Import `model.json` with `POST /api/v1/projects/import`; query the returned resource's `/model` and `/validation`. Expect schema 7 and the one warning above. JSON import provides canonical source; to retain the exact modular source layout, use `/api/v1/projects/import-source-project` with a SourceBundle containing entry `project.arcadia` and only the 30 reachable `.arcadia` file strings, keyed by slash-separated relative paths. Neither route reads the artifact target from your local filesystem.
+
+For transition replay, import `transition-before.json` instead. Submit `transition-request.json` to that baseline resource's `/transitions/preview` with its current ETag in `If-Match`. Review the returned plan, then follow the documented `/transitions/apply` protocol. Use the baseline resource for this exercise: the final model already contains the mapped records and subsequent refinements. This tutorial's automated evidence is core/source validation; it does not claim a separate native or HTTP acceptance run of this particular example.
+
+From the repository root, with the supported Rust toolchain available:
+
+```text
+cargo run --locked -p oa-core --example generate_release1 -- examples/release1
+cargo test --locked -p oa-core --test release1_teaching
+```
+
+Regeneration deliberately overwrites the generated source and JSON in the selected output folder. Copy the lesson before experimenting. No old examples are rewritten. The tests check deterministic regeneration, exact source/interchange parity, explicit transport and reply direction, behavior reuse, view identity/geometry, atomic rejection, and a reviewed name change preserving unrelated modules.
+
+The available SVG export is for architecture views. Faithful process, scenario and state-scene SVG export is outside this first-release export scope; the interactive behavior workspace is the authoritative rendering for this exercise.

+# Repair conversation acceptance notes
+
+Revision: lesson-1. Linked from `sa_conversation` by `repair_test_evidence`, relation Verifies, fragment `acceptance`.
+
+## Acceptance
+
+This is a reproducible teaching check, not field-test evidence for a real valve.
+
+- The Control room calls the Field technician across the operational channel; the correlated Reply reverses the actual Call pair.
+- The SA conversation uses the selected service boundary and explicit Standard client/provider ports. A synchronous operation interface and its Requires/Provides links describe the contract.
+- Both request and report functional exchanges are allocated through matching function/component ports and the boundary exchange.
+- The example carries input/output pressure values `420.0` and `320.0` against the declared 0..600 real type. Values and unit text are descriptive model data; no hydraulic simulation has run.
+- The remote reset and field-repair alternatives join before pressure confirmation. The field procedure and scenario conversation are reused through identities and explicit bindings.
+
+Run `cargo test --locked -p oa-core --test release1_teaching` from the repository root to reproduce the core/source oracles. The intentionally unfinished threshold-audit function remains a located coverage warning. Actual equipment safety assessment, executable control validation and field measurements are separate engineering work.

+# Repair/save native-v4 preparation — no launch performed
+
+Owner: Codex-9e8r6t /root/release_audit. Root operates the GUI and owns acceptance. `helper.py` is an adaptation of the reviewed native_v3 helper, with fail-closed gate/source admission and separate snapshot versus saved-oracle actions. No helper action, application, oracle, compiler or recovery operation was run during preparation. Only fixture copies/static checks and Python AST parsing were performed. Existing v3 data and packaging adapters were untouched.
+
+The new source commit is `33c6d83e9ba9a5b1310b1b627d7c40affcbcf15c`. Its 500 raw inputs must match `.local/text-repair-save-20260911/inputs1.json` and ZIP SHA256 `213fdb39ea7c3601b4baac674c3ab3ecc863ac44db1b092d922d3e24f26887b7`. Future launch requires all five exact successful gate commands/results, their stdout/stderr hashes, complete.json and the actual 755/0/1 full-suite log. The manifest's captured precommit HEAD remains eeeaa126; the launch commit is the committed byte-equivalent correction above.
+
+The GUI hash is read from successful `gui-build-result.json`, never copied from old v3. The helper uses root's preserved `.local/text-repair-save-20260911/gui-repair.exe`, verifies its size/hash against the actual binary record and copies it exclusively to trial/bin. Current receipt identifies B183EF31…B168848, 113,206,272 bytes, but this abbreviation is documentation only; executable admission uses the full actual receipt. F456 DLL and oracle967 hashes remain explicitly pinned.
+
+## Paths and future commands
+
+Base preparation directory already exists. **trial/** does not: launch refuses to overwrite it. Trial models, private profile/Desktop/APPDATA/TEMP, bin and checkpoints are created only on an explicitly authorized launch. The child environment has Windows-only PATH plus standard SystemRoot/SystemDrive/ProgramData/ALLUSERSPROFILE/PUBLIC values; no arbitrary parent credential/proxy environment is inherited. Python stdout/stderr are configured UTF-8 to avoid the earlier cp1252 print failure.
+
+Use `C:/Users/User/.cache/codex-runtimes/codex-primary-runtime/dependencies/python/python.exe` from repository cwd. Examples below are **not executed**:
+
+```text
+python .local/text-repair-save-native-20260911/helper.py launch --source-commit 33c6d83e9ba9a5b1310b1b627d7c40affcbcf15c
+python .local/text-repair-save-native-20260911/helper.py snapshot --model missing-include --label missing-before-apply
+python .local/text-repair-save-native-20260911/helper.py snapshot --model missing-include --label missing-after-apply-before-save
+python .local/text-repair-save-native-20260911/helper.py check --model missing-include --label missing-final-saved --after-visible-save
+python .local/text-repair-save-native-20260911/helper.py closed --observed-absent
+```
+
+Replace `python` with that full bundled executable. Available models: valid, release1, ambiguous, missing-include, recovery. A unique lowercase/hyphen label is required for every snapshot/check. Snapshot creates an exact disk copy and hash/journal receipt only, with no oracle or accepted-model claim. Check additionally requires root's explicit confirmation that a successful Save was observed, then invokes the pinned complete `same` oracle; valid/repaired ambiguity/repaired missing cases compare with exact valid four-file baseline, engineering with its release1 baseline, recovery with expected AFTER. Oracle stdout/stderr/status are retained even on failure. It refuses remaining save-journal files in a final acceptance checkpoint.
+
+`closed --observed-absent` is allowed only after root independently observes the relevant process/window absent. It records binary readback, not its own process observation or exit code. The helper never closes or kills an application.
+
+## Frozen fixtures and optional recovery sequence
+
+`fixtures/` has 64 files / 300,070 bytes. `fixture-manifest.json` SHA256 is `7bccf622c8e2ff42f9e71ac8e5d08ea27b3493c9ebc689ce5f7fbac9aa63f851`. The four ordinary model groups are byte-exact copies from the original pinned fixture manifest `edd4157f…ecc1ed`: valid (four files), ambiguous (four), missing include (four), release1 (37 total including 30 Arcadia). There are no profile/executable copies in the prepared fixtures.
+
+Recovery adds three small directories:
+
+* `recovery-expected-after`: exact valid four-file baseline; project title `Navigation — 救援`.
+* `recovery-expected-before`: only the entry project-title string changes to `Before interrupted save — 救援`; IDs, alias, includes, descriptions and the other three files are byte-identical.
+* `recovery`: disk initially equals AFTER, plus `.arcadia-save-project.arcadia.journal/{journal.json,0.before,0.after}`. The v1 journal has exactly one entry with path project.arcadia, before=true and write=true. The stage files are exact BEFORE/AFTER. This mirrors the accepted v1 contract in source_files.rs and repair_save_state_tests.rs; no core recovery was run in preparation.
+
+Entry BEFORE SHA256: `6e9abf4ecf24175b9f04a8db11fe182146581059628eb8769e869597401f262e`. AFTER SHA256: `79e26836c048a35aaf98b21ff006ae8ac931160abd9913b9e67b542303215414`.
+
+Optional native evaluator: first open the valid AFTER project; then open trial/recovery/project.arcadia. Inspect the interrupted-save banner and snapshot the disk/journal. Explicitly Apply the displayed AFTER source as in the headless regression, then invoke actual Recover. Recovery should remove the journal and restore BEFORE on disk while retaining the accepted AFTER graph/source. Snapshot immediately: this is **not saved acceptance**. Verify visible Unsaved changes and the close/cancel guard without discarding; explicitly Save the retained AFTER model. Only then run `check --model recovery --label recovery-final-saved --after-visible-save`, whose oracle expects exact AFTER. Do not call the helper to perform Recover or fabricate the post-Recover state.
+
+No native first-save deletion fixture is included; the headless tests cover it. The helper does not validate arbitrary alternate GUI builds or later source edits: any changed freeze needs a separately reviewed new helper/trial. Old navigation packaging adapters remain historical and must not be executed for this repaired candidate.

+# Repair/save native verification — 2026-09-11
+
+Native operator: Codex-9e8r6t `/root`. Independent archive and stored-evidence inspection: Codex-9e8r6t `/root/linux_readiness`.
+
+The corrected Windows GUI passed three bounded native repair workflows: missing include, duplicate alias, and interrupted-save rollback. Repaired accepted source remained visibly unsaved until explicit Save; attempted Close prompted and Cancel retained the work. After each final visible Save, the complete saved-model/source oracle passed with all four files and authored identities equal to the intended baseline.
+
+Root operated the native application. This report's author independently inspected stored screenshots and checked the exact saved files, receipts, and archive bytes without rerunning the application or oracle. [The correction report](release-text-repair-save-state-20260911.md) records implementation and the 755-test/Clippy gates; [raw native evidence](experiments/text-navigation-native-20260911/repair-save-native-v4/manifest.json) preserves this trial.
+
+## Identity and method
+
+Launch receipt: **2026-09-11 20:52:46 UTC**, PID **10016**, source commit **33c6d83e9ba9a5b1310b1b627d7c40affcbcf15c**. Admission bound the 500 input files and successful gate receipts to input ZIP SHA256 `213fdb39ea7c3601b4baac674c3ab3ecc863ac44db1b092d922d3e24f26887b7`.
+
+GUI: **113,206,272 bytes**, SHA256 `b183ef31f16b3986538b3f2aba8435eab45978635c47f99ca01be6e72b168848`. The bundled `libunwind.dll` SHA256 was `f45604a12e8bcd839fd86f667c1be1cc7c4f9da2b3c69ff381ac708f0e1ae7d4`. A private profile/TEMP and Windows-only PATH isolated the trial from the development toolchain. All 20 original screenshot captures include their metadata and show a **1442 × 932 outer window**.
+
+Edits, Apply, Close/Cancel, Recover and Save were performed through the GUI. The helper only launched, copied/read disk checkpoints, ran the pinned saved-equality oracle after the caller confirmed visible Save, and recorded binary readback. Snapshot receipts alone make no Apply or accepted-model claim. The oracle executable was SHA256 `967d9ba3c6fb3a7efb410833903ec94556ca2d48a67d5072c8bb160f40a00f9c`.
+
+## Observed outcomes
+
+| Trial | Visible state and before-save disk evidence | Final saved check |
+| --- | --- | --- |
+| Missing include | Captures 03–05: invalid Open, repaired draft, then Model in sync **and Unsaved changes** after Apply. Disk snapshot at 20:55:26 still contains the broken include. Captures 06–07 show Close warning and Cancel retaining the repair. | Capture 08 shows clean after explicit Save. Oracle at 20:55:51 exits 0; exact valid baseline, complete Project/IDs and all four source files. |
+| Duplicate alias | Captures 09–11: invalid Open, duplicate declaration removed, then Model in sync **and Unsaved changes** after Apply. Disk snapshot at 20:57:26 still contains the duplicate declaration. Captures 12–13 show Close warning and Cancel retaining the repair. | Capture 14 shows clean after explicit Save. Oracle at 20:57:52 exits 0; complete valid Project/IDs and four exact files. |
+| Journal recovery | Capture 15 and 20:58:52 snapshot retain AFTER plus the three v1 journal files. Capture 16 shows unchanged Apply clean while disk still equals AFTER and the recovery banner remains. Actual Recover removes the journal and restores BEFORE on disk at 20:59:11; capture 17 shows retained AFTER text now **unsaved**, with Model in sync. Captures 18–19 show Close warning and Cancel. | Capture 20 shows clean after explicit Save. Oracle at 20:59:36 exits 0; full intended AFTER Project/IDs and four exact files. |

Application stdout and stderr are empty. **No numeric process exit code was observed**; neither the helper nor this report infers one.
+
+## Scope
+
+No native failure occurred in these three repair trials. They resolve the false-clean defect observed in [GUI5478's historical native trial](release-text-navigation-native-v3-20260911.md). They do not repeat the entire navigation/engineering trial, establish minimum-size layout behavior, exercise native first-save deletion or injected reload failure, or establish package/release acceptance. The earlier GUI5478 record retains its own navigation/engineering scope. Linux/WSL remained paused.
+
+The archive retains preparation helpers and their original **pre-launch** README, all 64 frozen fixture files, all seven checkpoints, all 20 JPEG/metadata pairs, launch/admission/close receipts and empty/raw logs. The historical preparation README remains explicitly historical. Redundant final trial model trees are omitted only after exact byte equality with preserved fixtures/checkpoints was verified. Binaries/profile/cache are excluded; executable identity remains in receipts. No originals were removed.
+
+Archive verification passed for **166 payload files / 2,421,715 bytes**, plus manifest/readback. Manifest SHA256: `3a32afc0d93dafdead2066a7d1fddaf5fedddf99cf4a9b481cd7691007b6f9d9`. Readback SHA256: `b726cb6e8338488636fdd08c5254367fa44981aad19af18509839f7cf424a2cc`. The read-only verifier checks every payload, all fixture and checkpoint hashes, screenshot counts/dimensions, final four-file equality and the three actual oracle result records without rerunning an oracle. All 53 omitted duplicate trial files were matched to retained bytes.
