# Resume mobile expansion from the current local checkpoint

Current override 2026-10-22: maintained dev inherited PR141/142/143 and
MEX-20a/b. The new authorized batch MEX-20c/d/e/f is locally tested and complete,
with migration000111 and full-source acceptance. PR144 carries20b–f; next is
current-head guarded delivery, then MEX-21 only on renewed implementation scope. Use current PROGRESS over the historical guidance
below. Preserve the occupied primary checkout; use .worktrees/main-reconciliation.
No intermediate PR/merge/CI wait; source activation remains OFF.

Current checkpoint, 2026-10-22: MEX-00–07, MEX-09, MEX-10, MEX-17/18/19,
EE-00–03 and reviewed EE-11 are LOCAL_DONE / INTEGRATION_PENDING; use
[current PROGRESS](docs-planning-PROGRESS.md) and their linked evidence. The authorized
four-unit batch is locally complete: [MEX-10 ledger/report
reacceptance](docs-backend-evidence-mobile-expansion-MEX-10.md), [MEX-17 source
census](docs-backend-evidence-mobile-expansion-MEX-17.md), [MEX-18 scoped reader
acceptance](docs-backend-evidence-mobile-expansion-MEX-18.md) and [MEX-19 scoped
sanctions HTTP](docs-backend-evidence-mobile-expansion-MEX-19.md). MEX-19 remains
default-off and only disables scoped company reads. MEX-08 still requires EE-19;
EE-04/05 require their unmet source-admission/rights gates; MEX-20 enforcement
review remains retained. Current source checkpoints do not accept source
admission, later mobile journeys or production/commercial readiness. PR140, the
Go1.27.3 runtime update and its wiki mirror were already integrated separately
and must not be repeated.

## Foundation history

The foundation [MEX-00 audit](docs-backend-evidence-mobile-expansion-MEX-00.md) and
the subsequently authorized [MEX-01 registration contract](docs-backend-evidence-mobile-expansion-MEX-01.md)
and [MEX-02 exploration contract](docs-backend-evidence-mobile-expansion-MEX-02.md)
are LOCAL_DONE / INTEGRATION_PENDING. The earlier four-unit request selected
[MEX-03 baselines](docs-backend-evidence-mobile-expansion-MEX-03.md),
[EE-00 inventory](docs-backend-evidence-ev-support-EE-00.md),
[EE-01 qualification](docs-backend-evidence-ev-support-EE-01.md) and
[EE-02 types/numerics](docs-backend-evidence-ev-support-EE-02.md), now locally complete.
Qualification is not source admission: PBE rights and full-source/runtime/privacy
gates remain pending. Later implementation checkpoints do not satisfy them.
This file is continuation guidance, not additional execution authorization.

## Starting point for the next authorized agent

1. Read applicable AGENTS, FAST_EXECUTION, current PROGRESS and DELIVERY_WORKFLOW,
   then the [MEX-00 evidence](docs-backend-evidence-mobile-expansion-MEX-00.md) and
   [combined execution prompt](docs-planning-EV_SUPPORT_EXECUTION_PROMPT.md).
2. Inspect `.worktrees/mobile-expansion-plan`, `codex/mobile-expansion-plan` and
   actual maintained dev/main before acting. The foundation reconciles original
   plans `47fded8c` / `35accb9e` with dev `a2f8925c`, preserving both histories.
   Do not check out the old plan base as the implementation base. Do not reset,
   stash, cherry-pick an already inherited change or include another agent's edits.
3. Refresh remote refs when available. The foundation's remote check failed DNS;
   no remote current-head/CI acceptance was established. Work on maintained dev
   when available; otherwise isolate and reconcile normally under ADR-020.
4. The requested **MEX-10/17/18/19** batch is now locally complete and tested.
   The next authorized delivery step is to push maintained dev, open the
   protected dev→main batch PR, require current-head/base checks and merge only
   through the guarded workflow. **MEX-08 requires EE-19**, not just MEX-07;
   MEX-20 enforcement and EE-04/05 source admission remain held by their owning
   gates. Select one newly authorized bounded task at a time; no schema/UI
   changes before their owning dependencies, and required source gates cannot
   be mocked away.
5. Read the selected unit and linked rules; do not rerun the entire project for
   this audit. Relevant code/config/base changes invalidate affected evidence.
   The [dependency JSON](https://github.com/AlexandreZanata/brazil-fuel-prices/blob/c82823cb3010d26965923b319d636047620f48d1/docs/planning/EV_MEX_DEPENDENCIES.json) has no completion flags.

## Reuse and guardrails that must survive the handoff

- One free vehicle; extra vehicles Premium. Current technical ceiling3 and
  existing professional feature matrix remain until an explicit amendment.
  Preserve old vehicles/history and expired-account data-exit rights.
  [Registration v2](docs-product-VEHICLE_REGISTRATION_POLICY.md) and its23 worked
  examples are frozen; hosted vehicles.multiple admission is implemented in
  MEX-07; local quota/lease acceptance remains MEX-08 after EE-19.
- [Exploration v1](docs-product-MOBILE_EXPLORATION_CONTRACT.md) has54 shape and
  three counting examples in a separate schema without live endpoints. Reuse it
  for typed intent/source/clock/coverage/company filters and Android wording;
  actual semantics/SQL/HTTP/screens and source acceptance are still unimplemented.
- Reuse PRM cloud/ledger/metrics/subscription and Kotlin ports. Source coverage
  does not close Android journeys or real provider proofs.
- Keep EE capability/unit/tariff/source contracts ahead of dependent migrations
  and Android. PHEV is one vehicle; no fake electricity FuelProduct or zero cost.
  [EE-02 frozen contract](docs-product-EV_TYPED_DATA_CONTRACT.md) has46 shape and24
  exact Go/Kotlin/Rust examples; numerical oracles are not the runtime EE-11 engine.
- [MEX-03 actual baseline](docs-backend-evidence-mobile-expansion-MEX-03.md) distinguishes
  the in-memory picker from unused global search; target the real consumer and
  compare pinned workloads. Host SQLite/JVM does not establish phone latency.
- Reconcile OPT commits `f60bb3e2`, `8de22c24`, `6e8b306a` before repeating that
  work. Their persistence/no-store and real SQLite acceptance require review;
  don't blindly accept their phase3 declaration. Allocate Room versions from
  the actual combined database. Preserve Home commit `a2f8925c`.
- Close missing FQ scoped-read acceptance through MEX-18; MEX-20a–f are six
  real-source enforcement units. Current-company association is not historical
  site attribution. No source-global data is suppressed for lack of association.
- D receipts/business portal stays future-only until extreme consolidation and
  thousands of real clients, unless expressly requested earlier for that scope.
  iOS, charging control/payment, provider registration and activation stay held.
- Local source implementation and commits are distinct from publication,
  deployment, device changes and release certification. Follow the human's
  active authorization; this foundation does not publish or authorize those steps.

Deliver each task with actual targeted/risk tests, evidence, concise PROGRESS
and one atomic English commit. Report in Portuguese. Never convert an absent
test, provider permission, source sample or live access into PASS.
