Step 3 — 2026-10-23

Necessary/useful instructions

• Step 3 Completion Contract and early risk validation place snapshot/reconciliation/storage checks ahead of dependent UI stages; retain them because current signing recovery can reread a mutable form.

• Step 3 known-environment guidance preserves physical iPhone verification separately from browser-engine evidence and deployment acceptance; retain this distinction.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

Documentation-only runtime boundaries do not apply; no database/schema work is proposed.

Uncertain assessments

Six required fields per stage plus study bookkeeping exceed a typical rendered page even with concise bullets. The plan favors explicit stage contracts and recovery obligations over omitting required evidence; hour-sized stage targets remain estimates to validate during execution.

Step 1 — 2026-10-23

Necessary/useful instructions

• Step 1 review/approval and solution options keep the selected phone behavior explicit before implementation; retain the gate and concise comparison.

• RAILSPIKE.md Experimental Effort Estimation requires prior-exposure disclosure and exact references. Prior source investigation is disclosed and all three R1 hashes verified; retain this distinction from prospective measurement.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

Step 3/4 branching and commit instructions do not apply to this uncommitted Step 1 handoff.

Uncertain assessments

One-page guidance depends on rendering; the assessment keeps two options and concise scope but preserves the full multi-turn request and required study snapshot.

Step 2 — 2026-10-23

Necessary/useful instructions

• Step 2 shared-component inventory and completion boundary made enhanced signed standard replies and existing anonymous/no-script/Forte compatibility explicit. Retain these checks to prevent accidental expansion across shared submission code.

• Step 2 known-environment and recovery guidance makes physical keyboard evidence distinct from automated browser checks; retain this acceptance distinction.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

Documentation-only boundaries do not apply to this application change; Step 3/4 execution instructions remain gated.

Uncertain assessments

One-page rendering depends on layout; concurrent recovery and required study bookkeeping increase length. Requirements are grouped in five bullets and contain no implementation design.

Step 4 — 2026-10-23

Necessary/useful instructions

• Step 4 Before planning gate and organization rule produced planning commit 22ea20c19 before any summary/application changes. Stage Boundary Protocol kept six independently verified stage commits: de8ae2bcb, 91f1650fd, 62f54f3dd, 9ef125447, 8a6ddaca1, 0582fb867. Retain the summary/verification/commit order because it made the desktop, recovery, image and phone boundaries reviewable.

+- Step 4 canonical-contract guidance reused existing signing, prepared-post finalization, pending-card presentation and image reference/transport behavior. Normal-flow browser tests exposed lifecycle issues missed by source assertions: legacy pageshow cleanup, hidden-stack spacing, File persistence in WebKit and pointer Retry while the composer collapses. Retain rendered/recovery acceptance across shared consumers. +- Step 4 After evidence boundaries preserve physical iPhone and production acceptance as pending despite passing Chromium/Firefox/WebKit checks. The six-stage implementation is locally complete, not a deployment or device-acceptance claim. Retain this distinction and the actionable user checklist. +- Effort checkpoints preserve projected total 0.95 separately from retrospective scope 0.95, with prior exposure, stable cycle/R1/P2 and no measured work or invented acceptance. Host register/audit/ledger changes were excluded from the planning commit and included in final stage closeout. + +### Redundant/unnecessary instructions + +No supported findings. + +### Inapplicable instructions + +- Documentation-only runtime restrictions do not apply to this approved application change. No dependency approval or read-model schema migration was needed: dependency delta zero; no schema, manifest, lock, vendor or todo changes. +- Deployment, merge, push and source-comment replies were not authorized parts of implementation and were not performed. + +### Uncertain assessments + +- The six-field stage template could not fit the full recovery/device plan on one rendered page. Keeping concrete stage risks and evidence boundaries was useful; consider an explicit allowance for required checkpoint material outside the concise stage body. +- Stage size was targeted rather than measured; no reliable active-work timing was collected, so no measured-hour compliance claim is made. Actual device evidence remains an external acceptance dependency, not a successful automated substitute. + +### Handoff verification + +- Final application/closeout revision 0582fb867; planning plus six stage commits confirmed, each stage includes its implementation-summary update. Debug state remains enabled. This diagnostic addition is a separate log-only handoff commit, without amendment. +- Focused PHP 93/93; Chromium 16-theme both-route desktop/phone flow, Firefox/WebKit four-theme both-route flow, targeted identity recovery, and existing image/viewport/focus/board/layout/readiness regressions pass. JS/PHP syntax, diff and feature file-link checks pass. Physical iPhone, full suite, deployment and maintainer comfortable-fit acceptance remain pending.

Step 4 corrective handoff — 2026-10-23

Necessary/useful instructions

• Canonical-component reuse exposed a missed obligation in the first handoff: the normal post card, not merely a persisted-post ID plus pending-card body, is the accepted result. Correction a209befa0 imports the canonical thread card, binds its actions and verifies body HTML against the server output. Retain this explicit rendered-result requirement in acceptance checks.

• Recovery separation preserves an accepted publication when its full rendering fetch fails: Retry reloads rendering and never republishes. Real browser tests verify zero additional finalization requests and an untouched newer draft/selection.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

Fresh feature/step approvals are not required for this correction to the already approved canonical reconciliation contract. No new dependency, schema, deployment or unrelated .test* file change is included.

Uncertain assessments

The original test matrix was broad but accepted stripped placeholders; it did not establish full normal-post rendering. Browser/theme counts alone were insufficient evidence. Full-card regression assertions now include canonical HTML, long-tail content, working signed actions and rendering-only failure recovery.

Handoff

Correction a209befa0; Chromium/Firefox/WebKit both-route full-card tests, Chromium phone/four-theme checks, focused existing recovery checks and four PHP route/lazy-loader checks pass. Physical iPhone and production acceptance remain pending. Same scope/R1/P2 and 0.95 projected/retrospective assessments; no additional accepted study outcome.

Ordinary-page-flow corrective handoff — 2026-10-23

Necessary/useful instructions

• User clarified that the final view should resemble a reload, exposing the remaining artificial scroll region. Canonical-component and rendered-verification guidance supported removing the wrapper entirely and checking direct sibling placement plus server grouping/byline parity, rather than styling the inner scroller differently.

• Shared-consumer recovery testing caught the dedicated phone spacer insertion error and preserved native re-entry. The full long-history sweep exposed repeated canonical fetches; the corrected shared-request implementation has an explicit one-fetch-for-four-restored-items browser assertion.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

Fresh planning approvals are not required for this correction to the normal-page reconciliation outcome. Concurrent effort-ledger/research edits remain outside this change and are preserved; no new dependency, schema or navigation destination is introduced.

Uncertain assessments

The first broad theme sweep timed out from repeated thread rendering during restoration. Focused functional passes alone did not expose that load. The final sweep passes after sharing the in-flight canonical document; this is isolated local evidence, not physical-device or production acceptance.

Handoff

Implementation/evidence commit 62aec7e21, branch fix/reply-page-flow. Three-engine full-card and four-theme phone checks, Chromium all-16-theme continuation/recovery, focused PHP 93/93 and syntax/diff checks pass. Visual inspection covers ordinary-flow phone and desktop. No merge/push/deployment or new study outcome/rating is claimed; prior snapshots remain intact.
