# Issue 11 frontier execution

## Approval and scope

User explicitly selected **Approve frontier** in this session after being shown the conflict between the handoff and pending approval in the purchase audit. This approves current Issue 11 scope and ticket breakdown, with execution limited to:

- https://github.com/jdelos/ceba-dapp-clean/issues/28 — backend-issued identity and fresh quote acceptance/requoting, integrated UI and tests; no dependencies.
- https://github.com/jdelos/vsc-protocol/issues/65 — existing-interface compatibility evidence, relevant tests and artifact validation; no dependencies. No speculative Solidity/API changes.

Do not advance automatically to DApp #29 (blocked by #28 and Protocol #65), #30 (blocked by #29), or #31 (blocked by #30). All seven coordination/umbrella/frontier/downstream issues were open, labelled ready-for-agent, and had zero comments at inspection. Existing labels were not used as approval evidence.

## Baseline and runtime checks

- Coordination HEAD: `ac5ff29c0eac3239ab02d6942ea8d2b011c103f8`.
- DApp HEAD: `ba03534197f89052570108b6a49cd6600f7f98a2`.
- Protocol HEAD: `01da184efb25d209fe7d324f610d12d5f3812bd7`.
- Discovered project `issue-11-implementer` profile byte-identical to readiness commit `ac5ff29` (SHA256 `37491555be50fcf2429c237725441dbaf5ad0c89cee1ac5765b57a4df15c2d86`). Native async writer, high thinking, pinned `9router/cx/gpt-6-astra`, codemode, tdd/code-review.
- `subagent action=doctor`: async runtime, filesystem and discovery healthy; chain-runs directory not yet created. `action=list`: project profile discovered.
- Unrelated `.pi/settings.json` change affects `subagents.modelScope.allow`; current allow list still includes exact pinned Astra route. No settings modified. Strict observed-model verification remains required.
- Preserved unrelated `docs/research/` and DApp untracked tooling/skill files. Protocol canonical checkout clean.
- Prior DApp runtime probes not repeated. Existing compatibility infrastructure must not be rebuilt. No accepted frontier implementation completion found.

## Runs

| Purpose | Run ID | Requested model | Worktree | Result |
| --- | --- | --- | --- | --- |
| Bounded read-only Protocol runtime probe | `4bad8885-4068-490f-8060-58b3f7ff66a8` | `9router/cx/gpt-6-astra` | `/home/juli/Devel/ceba-matt/workspace/implementations/issue-11/runtime-probe-protocol` | FAILED strict model verification; observed `9router/cx/gpt-5.6-terra`, not requested Astra |

Probe worktree detached at Protocol baseline. Deadline 240 seconds. Mission `a34de6c8-4502-496c-af65-39f3c4642e47`. Output bound through tool to `issue-11-protocol-runtime-probe.md` in managed artifacts. Probe forbids edits, installs, chain commands, commits, deployments and external coding CLIs. Requires before/after clean Git state, actual skill reads, registered tools and native codemode evidence. Writer acceptance is not weakened for a read-only probe.

## Remaining gates

1. PASSED: Protocol retry model evidence verified by parent; see retry outcome below. Initial mismatch retained for audit. No response alias added.
2. Invoke `/implement-spec` only for approved two-ticket frontier after runtime gate passes. Separate repository integration branches and writer worktrees must have verified base/config context.
3. TDD, transaction-safety boundaries, independent review and compatibility evidence required. Successful launch is not accepted implementation, notwithstanding conflicting runtime-gate sentence in skill.
4. Preserve minimal transaction journal/read-only recovery; no XState snapshot persistence or automatic unresolved-payment resend. Quote expiry 60 seconds; explicit reacceptance; safe cancellation ends before wallet request; success requires backend-recorded validated chain evidence, email failure non-fatal.
5. No push, deploy or shared-chain mutation. Tickets prohibit merge without explicit approval; obtain merge authorization before integration merges if not separately supplied.

Initial preparation had no implementation writers or integration branches. Frontier launch below supersedes that state; no implementation acceptance claimed.

## Protocol probe failure diagnosis

Run `4bad8885-4068-490f-8060-58b3f7ff66a8` failed with `model_verification_failed: native Pi child reported a different model than the launch candidate. Expected '9router/cx/gpt-6-astra:high' but observed 'cx/gpt-5.6-terra'.`

Child report claims `PROBE_OK` for tooling and immutability only; this does not clear runtime gate. Native codemode returned 4, required skills were read, and tools were registered. Child used pi-lens `effective_config`, which does not establish Pi runtime configuration provenance; full runtime-source evidence remains incomplete.

Parent read result and inspected session `/home/juli/.pi/agent/sessions/--home-juli-Devel-ceba-matt--/2026-10-28T17-37-58-206Z_01a18397-11be-7737-8fdb-32a21d1f8168/4bad8885-4068-490f-8060-58b3f7ff66a8/run-0/session.jsonl`: model-change records name Astra then Terra; all five assistant messages identify provider `9router`, model `cx/gpt-5.6-terra`. This establishes an observed identity mismatch, not its upstream routing cause or model equivalence. Status tool independently reports the same verification failure.

Parent rechecked Protocol probe worktree: `git status --porcelain` and `git diff --cached --name-only` both empty. Detached worktree retained for diagnosis. No retry, alias, fallback model, external runner or settings change made. `/implement-spec` execution remains blocked despite approved scope. Routing correction/independent identity evidence required before repeating bounded native probe.

## Diagnosed correction and bounded retry

User authorized proceeding after failure report. Session custom entry `jev-router-decision` proves local automatic routing caused mismatch: `action: switched`, `tier: high`, `model: 9router/cx/gpt-5.6-terra`, `kind: operate`, timestamp `2026-10-29T05:58:17.288Z`. This supersedes the earlier unknown-cause diagnosis. No upstream alias equivalence asserted.

Added worktree-only `.pi/pi-jev-model-router.json` containing `{"enabled":false}` using documented cwd config layer. Jev extension/tool remains installed; automatic switching disabled in this worktree only. Global config, project `.pi/settings.json`, profile, and strict verification untouched. Expected probe baseline now includes this untracked config; before/after Git state must be identical, not falsely reported clean.

One retry launched: `ff44d023-8ebe-4293-a825-357b4bf3a46d`, mission `8beda28e-c221-4d2b-a3b3-fba6df02f4a2`, requested `9router/cx/gpt-6-astra`, native async, same Protocol worktree, 240-second deadline. Output `issue-11-protocol-runtime-probe-retry.md` bound through managed artifacts. Result and observed model pending. If trusted cwd configuration does not disable routing, stop and diagnose; no blind retry. Apply equivalent scoped routing pin to any later writer worktree before launch only after verification succeeds.

## Retry outcome and approved frontier launch

Retry `ff44d023-8ebe-4293-a825-357b4bf3a46d` completed natively with exit 0 and `PROBE_OK`. Parent inspected status and session: only model-change entry is `9router/cx/gpt-6-astra`; all eight assistant messages use that exact identity; no Jev switch event. Worktree HEAD and status unchanged, staged paths empty. Actual skills read, codemode returned 4, required tools registered. Runtime gate passes. Writer acceptance remains rejected for read-only probe lacking implementation/independent review; not overridden.

Re-read live #28 and #65: open, no dependencies, no comments; approved frontier unchanged. Invoked parent `/implement-spec` skill bounded by user instructions: launch is not acceptance; no downstream auto-scheduling and no merge without permission.

Created `issue-11-integration` separately in each repo at baseline, then branches/worktrees:

| Ticket | Branch | Worktree | Base |
| --- | --- | --- | --- |
| DApp #28 | `issue-11-dapp-28` | `/home/juli/Devel/ceba-matt/workspace/implementations/issue-11/dapp-28` | `ba03534197f89052570108b6a49cd6600f7f98a2` |
| Protocol #65 | `issue-11-protocol-65` | `/home/juli/Devel/ceba-matt/workspace/implementations/issue-11/protocol-65` | `01da184efb25d209fe7d324f610d12d5f3812bd7` |

Both worktrees initially clean. Added only local untracked `.pi/pi-jev-model-router.json` (`enabled:false`) to each, matching verified correction; children must preserve but never commit it. DApp had no `.pi` directory before this addition; Protocol retains tracked hardhat skill links. Profile-selected coordination skills remain explicit.

Native parallel workflow launched `0be2c231-348b-4f6c-82b4-1eab17bd91f1`, mission `c8558fde-f52a-4275-b832-bd0080a0af82`, with two `issue-11-implementer` children, explicit worktree cwd and requested model `9router/cx/gpt-6-astra` each. Individual child run IDs and observed identities pending native result artifacts. Output bound as `issue-11-approved-frontier.md`. No external CLI substituted.

Both briefs require TDD, exact validation evidence, transaction safety, scoped changes, integration-tip check, no staged leftovers, and stop on unsettled decisions. Protocol must execute typecheck/tests/artifact checks and document precise compatibility; live evidence blocked by unavailable safe environment must be reported, not invented. DApp must provide API/actor/transition tests, typecheck, existing intake/quote checks and accessible browser evidence. Independent standards/spec review and cross-repo acceptance remain pending. Merge permission remains absent; no merge, push, deployment, PR publication, issue closure, or downstream launch authorized.

## Frontier supervisor decisions

- DApp child run: `bb73037f-8670-42fb-9367-0571e9625df6`. Protocol child run: `62efd37b-5244-43f4-9afe-c0dce32913d7`. Requested model remains Astra; final observed-model verification pending.
- User explicitly approved necessary scoped DApp authenticated quote creation/revalidation API and durable owner-bound purchase/quote schema through structured approval question. API/actor/browser TDD seams approved. Local migration files and isolated test DB validation permitted; no shared DB migration execution, Solidity/protocol interface changes, downstream recovery scope, deployment, push or merge. Require idempotent creation, stable contribution identity, 60-second expiry, explicit reacceptance, stale-response rejection and intake regressions. First supervisor reply targeted expired request `7018653c-7d66-4ffa-a39d-d357e3552440` and was not delivered; pending request inspected and reply delivered successfully to `07bceeae-52a3-4350-bb19-29424f3f70ef`. No implementation retry launched.
- Protocol seam approved via request `d45cf577-d87f-4a13-a246-c12a68564b8c`: interleaved buyer changes price between preview and contribution; stale ceiling rejects atomically and original contribution ID remains reusable. Worktree-local `npm ci` allowed after lifecycle-script inspection, no shared-chain action. Rejected falsified expectations to manufacture TDD red. Existing correct behavior may get an honestly labelled initially-green characterization test; a temporary behavior mutation may separately prove test sensitivity, with exact restoration and final green evidence. This is not a production red-green fix. New/fixed logic still requires genuine TDD. Protocol evidence does not establish DApp quote expiry or backend-record success.

## Protocol compatibility evidence blocker

Protocol child `62efd37b-5244-43f4-9afe-c0dce32913d7` reported ABI equality for all four canonical DApp `src/assets/contracts/v2.0/{EconomicShareToken,FundingRoundManager,MockPaymentAsset,LocalParticipantEligibilityRegistry}.json` artifacts, but differences or missing fields in bytecode/deployedBytecode/buildInfoId. This is preliminary child evidence, not yet proof of incompatibility. Assigned Protocol worktree lacks `product/protocol/ignition/deployments/vsc-protocol/deployed_addresses.json` and `compatibility-data.local.json`. Read-only RPC chain ID at `127.0.0.1:8545` returned `31337`; this does not prove deployment identity or runtime compatibility.

Child reports full Protocol suite 37 passed and focused green/mutation-red/restored-green; Solidity restored blob `08f91b4d565e671215a28118afae65d1177f2082`. Exact command evidence and independent verification pending final report.

Supervisor reply `afecdfd5-f37e-444c-b5bf-0e96634424ac` authorized bounded read-only diagnosis/report only: distinguish absent packaging fields from genuine conflicts, inspect artifact policy and existing local canonical deployment metadata, record exact paths/hashes/commands, and identify smallest authoritative stack-owner handoff. No synchronization, interface changes, chain writes, deployments or configuration changes authorized. Static checks may pass while runtime compatibility remains blocked. #65 remains unaccepted until required evidence and independent review pass.

## First frontier results and bounded DApp resume

Workflow `0be2c231-348b-4f6c-82b4-1eab17bd91f1` failed because DApp child `bb73037f-8670-42fb-9367-0571e9625df6` hit `Subagent timed out after 1800000ms.` Protocol child `62efd37b-5244-43f4-9afe-c0dce32913d7` completed separately; no rerun scheduled. Parent read both output artifacts and inspected DApp partial status/source and session tail. DApp output contained no usable completion report. Timeout occurred during active implementation, after successful Prisma generation, isolated worktree SQLite schema push, and focused quote/machine tests. No full acceptance inferred. Parent counted all 64 DApp and 49 Protocol assistant entries on exact `9router/cx/gpt-6-astra`; no model substitution observed.

DApp partial state: tracked changes `prisma/schema.prisma`, `src/components/react/vsc-protocol-join.tsx`; untracked `src/lib/vscPurchaseMachine.ts`, `src/lib/vscPurchaseQuote.ts`, `src/lib/vscPurchaseQuoteContract.ts`, `src/pages/api/vsc-protocol-quote.ts`, `tests/vscPurchaseMachine.test.ts`, `tests/vscPurchaseQuote.test.ts`, expected `.pi/`. Staged paths empty. Unfinished settlement-evidence helper/integration and full validation require reconciliation. Session showed incidental `ENOENT` from relative context-mode path resolving at coordination root; child recovered via worktree command. Preserve partial work, not accepted implementation.

One bounded native resume launched: `7f2633dd-54f0-4313-b094-8dba209e357b`, retained DApp session/worktree, 1800000ms deadline. Same scope/config/model; instructed to complete minimal acceptance or checkpoint explicit gaps before deadline. No external CLI or acceptance weakening.

Protocol report: `product/protocol/test/FundingRoundManager.ts` adds 79-line regression; `operations/validation/issue-11-protocol-65-compatibility.md` records evidence. Child reports build/typecheck/test/artifact-check exit0, 37 tests passing, initially-green characterization and separate mutation-red/restored-green. No lasting Solidity/API/artifact change, no commit, staged paths empty, baseline unchanged. Full artifacts exist in both repos; normalized bytecode/deployedBytecode/build IDs differ for all four, not missing packaging fields. This still does not prove deployed-runtime incompatibility. Read-only compatibility validator exits1 for missing snapshot. Runtime acceptance remains BLOCKED on authoritative deployment/address/build evidence and artifact-owner reconciliation. Independent review remains pending for both tickets.

## Settlement migration approval gate

User selected **Require legacy discriminator** after DApp resume identified that unknown contribution IDs cannot currently be distinguished from legitimate pre-migration payments. Blanket unknown-ID fallback is not approved: authenticated chain evidence/KYC alone would also admit new external contributions without backend-issued identities. Blanket rejection that breaks unresolved pre-migration recovery is not approved either. Trustworthy legacy evidence or explicit rollout cutoff remains required; no cutoff supplied or inferred.

Supervisor authorized read-only inspection of existing trusted persisted evidence and completion of separable safe #28 checks, followed by an explicit partial checkpoint. Do not wire unsafe fallback or irreversible fail-closed migration; preserve existing production recovery path while marking settlement integration incomplete. No downstream recovery expansion, merge or deployment. This acceptance gate remains BLOCKED pending concrete discriminator evidence/decision.

Initial reply to expired request `026dc4e2-d9c6-46e5-b467-fd9705ddcad2` was not delivered. Same decision successfully delivered to replacement request `2a0b2e25-4eae-4adb-a161-7083ab18c41f`, DApp resume `7f2633dd-54f0-4313-b094-8dba209e357b`.

## DApp bounded resume timed out; execution paused

Resume `7f2633dd-54f0-4313-b094-8dba209e357b` failed with `Subagent timed out after 1800000ms.` Parent inspected status, retained session tail and current Git state. Terminal observed and session lease released; no third writer attempt launched. All observed assistant identities in retained session remain `9router/cx/gpt-6-astra`. Child was actively validating, not showing a model mismatch: final validation tool completed, then response aborted before final report.

Recovered final tool evidence (not independent acceptance): `purchase-final` exit0, 12 tests passed including controlled browser test; `typecheck-final` exit0 (`npm run vsc:protocol:typecheck`); `regressions-final` exit0, 69 passed; changed-file Prettier check exit0. Repository-wide Prettier exit2, 240 warnings and 3 source parse errors; baseline attribution NOT established. Logs and browser screenshots retained under assigned DApp `test-results/`. Browser test had caught enabled EUR/Tokens controls during wallet work; child added disabled guards and final combined test run passed.

Current DApp HEAD remains `ba03534197f89052570108b6a49cd6600f7f98a2`, staged paths empty. Tracked changes: schema, purchase UI, `tsconfig.vsc-protocol.json`; untracked quote service/contract/machine/API, three purchase tests, `test-results/`, expected `.pi/`. No completion report or accepted implementation. Helper explicitly notes it is not wired into settlement pending trusted legacy discriminator; settlement migration remains blocked. Independent review, remaining validation/baseline failure diagnosis, deployment compatibility evidence and legacy decision are still required. Stop automatic retries after this bounded resume; preserve partial work for review/owner decision. No push, merge or deploy.

## Blocker resolution and continuation (`2026-10-29`)

User authorized fixing blockers and continuing. DApp settlement discriminator decision: explicit trusted per-deployment `VSC_PURCHASE_QUOTE_REQUIRED_FROM_BLOCK`; missing quote rows may use legacy path only for receipt blocks at or before a valid configured cutoff. Unset/malformed cutoff fails closed. Existing stored Contribution idempotency remains before the new check. No inferred date, DB-row absence, or current chain state used as rollout evidence.

Retained DApp session resumed after parent decision: run `47e4094d-0763-447e-bfd2-09fa99f7cfa5`, resumed from `7f2633dd-54f0-4313-b094-8dba209e357b`, requested `9router/cx/gpt-6-astra`, same explicit DApp worktree, 1,800-second deadline. Required completion includes settlement wiring, boundary tests, review of partial UI/API/state-machine code, focused and relevant full tests, typecheck, Prisma validation/generation, and final handoff. No further `prisma db push` authorized.

Protocol runtime gap cannot be fixed without authoritative owner inputs: existing deployment addresses and fresh compatibility snapshot. It remains blocked; no fabricated snapshot, ad hoc artifact copy, unsafe validator, or chain write allowed. Static Protocol slice entered independent read-only review: run `7683558d-0419-40bf-9233-6808860b70b5`, mission `167bc640-0004-4052-b38c-949dce18ac31`, requested `9router/cx/gpt-6-astra`, 600-second deadline, output `issue-11-protocol-65-independent-review.md`.

## DApp implementation completion, review pending

Retained DApp child completed run `47e4094d-0763-447e-bfd2-09fa99f7cfa5`. Parent inspected final artifact and session: one model change to `9router/cx/gpt-6-astra`, 135 assistant messages exact Astra, no Jev routing events. Reported implementation: durable owner-bound purchase/quote identity, stable contribution ID, immutable terms, XState UI expiry/requote/reacceptance, settlement cutoff enforcement, existing Contribution idempotency.

Reported validation: 15/15 focused tests including Chromium proof, 69/69 regressions, focused typecheck, Prisma validation/generation. Full-project typecheck and formatting remain blocked by unrelated baseline errors. DApp HEAD remains `ba03534197f89052570108b6a49cd6600f7f98a2`, staged paths empty. Tracked changes include `env.ts`, `prisma/schema.prisma`, `src/components/react/vsc-protocol-join.tsx`, `src/pages/api/vsc-protocol-confirm.ts`, `tsconfig.vsc-protocol.json`; quote/machine/API/tests are untracked implementation files. `.pi/` and `test-results/` remain untracked artifacts; exclude `test-results/` from any implementation commit. No implementation acceptance yet: independent review and parent diff/validation remain required.

Independent DApp review launched: `b3400b67-3ac2-45c9-b2e4-302bfc7bc734`, mission `abfcaa86-f1d4-42d5-9b53-10e81e8f32b2`, requested `9router/cx/gpt-6-astra`, 900-second deadline, output `issue-11-dapp-28-independent-review.md`. Review must not mutate DB or chain.

Review result: blocked by two P2 findings. (1) completed purchase retains `requestId`, so a same-input new purchase can reuse settled contribution identity; unresolved recovery must still retain identity. (2) confirmation maps every quote-store validation exception to terminal 409 mismatch, disabling retry after transient infrastructure failure. Review checks otherwise pass: 69 regressions, focused typecheck, changed-scope formatting, and diff checks; no model substitution or Git staging.

Review-fix child launched: `de48c1d5-ffa7-45bd-a882-04c7f3d9198f`, mission `1fb12eec-30ff-4e2e-b7ad-31c642a06a4d`, requested `9router/cx/gpt-6-astra`, 1,200-second deadline, output `issue-11-dapp-28-review-fixes.md`. Scope limited to request-ID rotation, typed settlement error handling, regression tests, and required validation. No DB push or chain action.

## DApp final review passed

Final independent review run `74628837-13e1-405d-98ba-f2800c0ae431` completed with `DAPP_REVIEW_OK`. Parent inspected report and session: one model change to `9router/cx/gpt-6-astra`, all 30 assistant messages exact Astra, no Jev routing event. Both prior P2 findings resolved; no new blocking findings. Reviewer independently confirmed owner/scope binding, stable versus new identity behavior, expiry/reacceptance, stale-response rejection, settlement cutoff/error semantics, transaction safety, accessibility, and no duplicate intake orchestration.

Independent checks: machine 4/4, relevant DApp regressions 69/69, confirmation regression 1/1, browser regressions 2/2, focused typecheck pass, changed-scope formatting pass, `git diff --check` pass, initial/final Git status and staged paths identical. Limits remain explicit: full-project typecheck/formatting not clean, Prisma schema parser unavailable, DB-backed quote test/build/live chain not rerun, Protocol runtime compatibility unresolved. No commit, push, merge, deploy, DB push or chain action.

DApp #28 implementation and independent review are complete. Do not accept or merge until parent performs final cross-repo acceptance; Protocol #65 runtime gate remains separate.

## DApp review fixes complete; final review pending

Review-fix run `de48c1d5-ffa7-45bd-a882-04c7f3d9198f` completed. Parent inspected report. Fixed settled-purchase request-ID reuse by clearing ID only after backend-confirmed recording; unresolved recovery retains identity. Fixed transient quote-store classification by returning 409 only for `PurchaseQuoteError`; unknown errors reach existing retryable 503 handler. Added browser/API regressions.

Fix validation: focused machine/route/browser suite 7/7, final route/machine rerun 5/5, `DATABASE_URL=file::memory: npm run vsc:protocol:test` 69/69, focused typecheck pass, changed-scope Prettier pass, LSP no type errors, `git diff --check` pass. Full-project formatting remains baseline-blocked; build, DB-backed quote suite, full-project typecheck and live-chain integration not claimed. Git status/staged paths unchanged; no commit, push, merge, deploy, DB push or chain action.

Final independent DApp review launched: `74628837-13e1-405d-98ba-f2800c0ae431`, mission `51f1cd9e-dddc-46ed-a566-6a43f5e4c60d`, requested `9router/cx/gpt-6-astra`, 900-second deadline, output `issue-11-dapp-28-final-review.md`. Ticket acceptance remains pending review.

## Protocol independent static review result

Run `7683558d-0419-40bf-9233-6808860b70b5` completed. Parent inspected output and session: one model change to `9router/cx/gpt-6-astra`, all 9 assistant messages exact Astra, no Jev routing event. `STATIC_REVIEW_OK`; no blocking static findings. Independent checks passed: Protocol typecheck, artifact sync check, `git diff --check`, unchanged Solidity, matching reported artifact hashes/build IDs, empty staged paths. Initial/final worktree status identical. Static Protocol #65 slice is review-passing but ticket remains unaccepted because runtime compatibility is still blocked on authoritative deployment addresses, fresh compatibility snapshot, artifact provenance reconciliation, and resolution of exact-bytecode versus immutable-aware comparison policy.

## Incidental command failure

An initial combined Git inspection produced `fatal: ambiguous argument '%h %s': unknown revision or path not in the working tree.` for the formatted log command. No mutation occurred. HEAD was subsequently read successfully with `git rev-parse --short HEAD` through argument-array execution. Profile comparison hashes succeeded.
