Invite signing readiness — Railspike debug log

Debug mode: enabled Mode source: Host-root .railspike_debug_on exists; new cycle default inherited.

2026-10-27 UTC — Step 1

Necessary/useful instructions

Source: step1_solution_assessment.md, Objective and Recommendation. Comparing prevention with bounded recovery makes the first-attempt expectation explicit; normal entry excludes Account preconditioning that hid the reported failure in prior checks. Retain the vertical-slice requirement.

Source: RAILSPIKE.md, Experimental Effort Estimation. Source inspection preceded scoring; missing pristine intake is recorded honestly, and the distinct cycle does not overwrite QR estimates or count as an accepted outcome. Retain exposure and stable-ID rules.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

No implementation, branching or commit cadence applies during Step 1. Existing QR approvals do not authorize this identity repair.

Uncertain assessments

Source shows an unchecked boundary between session-derived issuer and browser signing key. It does not prove the user's exact cause. Reproduction with real cryptographic verification is required before selecting the repair; no production key material or invitation secrets were requested.

2026-10-27 UTC — Step 2

Necessary/useful instructions

Source: step2_feature_description.md, Completion boundary and known-user recovery. The requirements explicitly replay direct Invite entry without Account preconditioning and distinguish automatic reconciliation from genuinely unusable saved keys. Retain this user-outcome boundary.

Source: step2_feature_description.md, Risks and shared components. Identity consistency, bounded pre-write recovery and shared-consumer regression coverage are explicit before implementation planning. Retain these requirements to avoid treating every signature rejection as a reason to retry.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

Documentation-only delivery rules do not apply to the planned application repair. Physical-camera acceptance belongs to the separate QR appearance cycle, not signing readiness.

Uncertain assessments

The incident's precise cause and device/browser remain unknown. A real cryptographic reproduction is required before repair; passing a preauthenticated happy path or merely replacing the technical message will not establish resolution.

2026-10-27 UTC — Step 3

Necessary/useful instructions

Source: step3_development_plan_do.md, Key Risks and dependencies. The reproduction stage explicitly gates session/signing repair, retaining the unresolved diagnosis instead of turning a hypothesis into an implementation assumption. Retain this gate.

Source: step3_development_plan_after.md, normal-flow completion. Direct Invite entry, preserved keys/approval, real recipient redemption and ambiguous-result recovery are acceptance conditions rather than Account-preconditioned happy-path checks. Retain this requirement.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

Schema migration and documentation-only boundaries do not apply. QR visual corrections and polarity changes are outside this approved reliability cycle.

Uncertain assessments

Stage sizing assumes existing fixture/authentication machinery can reproduce the defect without a wider redesign. Missing reproduction blocks dependent repair; a materially different cause requires replanning. No browser/device-specific incident confirmation is claimed.

2026-10-27 UTC — Step 3 diagnostic revision

Necessary/useful instructions: The Step 3 reproduction gate produced the exact failure/Account-recovery sequence on unchanged code and revealed missing public-Invite authentication wiring. Retain the requirement to test normal entry without Account preconditioning. Redundant/unnecessary instructions: No supported findings. Uncertain assessments: Session/key disagreement is demonstrated; its origin in the user's browser remains unknown. Preserve that distinction instead of equating controlled reproduction with historical telemetry. State: User approved the bounded diagnostic discussed after the plan. Step 3 implementation approval remains pending. No new stage completion or score is inferred; see invite_signing_readiness_reproduction.txt.

2026-10-27 UTC — Step 4 completed handoff

Debug mode: enabled, restored from the Step 4 artifact; no override. Approval: Subsequent explicit Approved Step 3 authorized implementation; the earlier diagnostic-only boundary is historical. Final implementation revision: 456cada2d on feature/invite-signing-readiness.

Necessary/useful instructions

Source: step4_implementation_after.md, Final Verification Checklist items 1–4. The four stage commits each contain their summary update; planning commit 554114c2c precedes them and contains only approved planning artifacts/navigation. Five commits satisfy the one-plus-four gate. Real direct-entry, recipient redemption and recovery checks exposed behavior that Account-preconditioned checks missed. Retain the normal-flow completion requirement.

Source: step4_implementation_after.md, Effort estimation and items 6–7. Original projections and separate retrospective assessments remain in the summary and host ledger; acceptance remains pending. Explicitly separating focused verification from full-suite and user-browser outcomes prevents overclaiming this repair. Retain these boundaries.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

Schema migration, dependency installation and external-system deployment checks are inapplicable: this cycle changes none and authorizes no deployment. Documentation-only runtime exemptions are inapplicable to this application repair.

Uncertain assessments

The controlled session/key mismatch and exact Account recovery were reproduced and repaired. The origin of the historical mismatch in the user's browser remains unknown; production and user-device confirmation are pending. Chromium fixture success is not incident telemetry. Retain this distinction.

Final verification record

Passed: Four stage-scoped commits and summary updates; planning organization/count gate; normal UI issuance, redemption, revocation and recovery; 112 focused PHP checks, Node checks, existing zero-click regression, 160 rendered UI states, syntax and diff checks. Full evidence and limitations are in the Step 4 summary. Passed: Scope and study closeout recorded in the final stage commit; no todo.txt edits, dependency changes or schema changes. Unrelated QR review edits remain uncommitted in three planning documents. Pending: User-browser/production confirmation and maintainer comfortable-fit judgment. Full suite not run; no full-suite claim. No merge, push or deployment performed. Baseline failure: Exact detached-signature rejection twice before Account reconciliation on original code; permanent regression passes after repair in both access modes. Handoff: This addition is a separate log-only commit after final stage 456cada2d; completed stage commits are not amended. QR visual follow-up remains outside this reliability cycle.
