app_sessions — Railspike debug log

2026-11-03T01:45Z — Step 1 (solution assessment)

Mode: enabled from the project marker (new workflow, no explicit request). Agent: Claude (claude-opus-5-5).

RAILSPIKE.md › Effort estimation, intake checkpoint ("Preserve initial scoped estimate ... before detailed implementation inspection"): forced recording 0.90 before opening session code, so the Step 1 projection is visibly a reaffirmation rather than a reconstructed intake. Retain.
step1_solution_assessment.md › Structure, ## Original Query verbatim: kept the user's long, multi-part request intact while the outline corrections live in their own section. Retain.
concepts.md › Planning ("Mark missing entries as proposed"): surfaced that no session/sign-in concept exists despite many plans touching it. Retain.
Host AGENTS.md › Principles ("Read PRINCIPLES.md before weighing options"): caught that the outline's "redirect http to https" contradicts the HTTP-alongside-HTTPS principle. Retain; the host instruction did work Railspike itself does not do.

RAILSPIKE.md › Experimental Effort Estimation and effort-estimation.md › Extended estimates / Estimate presentation: the same presentation rules (bold Estimate: lines, plain numbers, non-additive) are stated three times across the two files plus the Step 1 file. Suggest consolidating to one canonical section with links.
Host ledger effort_estimation_trial.md › P2 plus RAILSPIKE.md › Continuing collection repeat worktree-deduplication rules irrelevant to a single checkout. Clarify as conditional.

Step 3/4 commit, branch and organization rules; one-shot mode; follow-up branch reuse.
Third-party dependency inventory: no option proposes a dependency (all use PHP's built-in SQLite/HMAC).

Warning sign "Step 1 >1 page" conflicts with a request that asked for options plus revocation, migration, https, outline corrections and related fixes. The artifact runs slightly over one page; it is unclear whether the limit should yield to explicit user scope. Suggest stating which wins.

Mode: enabled (inherited from Step 1). Agent: Claude (claude-opus-5-5).

step2_feature_description.md › Known user or environment ("Evidence from a different supported platform does not satisfy this condition"): made the iPhone Safari check an explicit acceptance item instead of letting a Chromium replay stand in for it. Retain.
step2_feature_description.md › Guardrails ("A feature is a normal-flow vertical slice"): pushed the completion boundary onto ordinary sign-in entries and Deploy POSTs rather than "a new session store". Retain.
RAILSPIKE.md › Enhancement Requests: kept the Step 1 inventory's deferred client items visible as out-of-scope rather than silently dropped. Retain.

step2_feature_description.md › Effort estimation repeats the presentation and attribution rules already given in RAILSPIKE.md and effort-estimation.md. Suggest a single link.

"Avoid ... database schema" vs. a new session store: the store is unavoidable for Option A. The description names it without schema detail; it is unclear whether Railspike expects an explicit schema-exception note at Step 2.

Mode: enabled (inherited). Agent: Claude (claude-opus-5-5).

step3_development_plan_do.md › Additional requirements ("include a stage that replays each reported failure"): produced Stage 6's same-host http/https replay, and the rule that it must fail on main first, instead of relying on unit tests of cookie names. Retain.
step3_development_plan_do.md › Guardrails ("split stories into vertical slices, not layers") together with the stage commit cadence: forced a behavior-neutral test-helper pre-pass (Stages 2–3) so each stage commits with a passing suite rather than a broken mid-cutover state. Retain.
step3_development_plan_do.md › Key Risks **High risk:** prefix: made the sign-everyone-out cutover visible at the top. Retain.

step3_development_plan_after.md › Effort estimation and the Do file's Effort estimation repeat the non-additive and stage-work semantics. Suggest stating them once.

Stage sizing "<=1 hour or <=50 lines": Stage 4 is mostly deletions and exceeds 50 lines. The plan adds a split trigger on non-deletion lines; it is unclear whether deletions count toward the limit.
One-page limit: seven fully specified stages with extended estimates exceed one page. Unclear which rule should yield.

Mode: enabled (inherited). Agent: Claude (claude-opus-5-5).

step4_implementation_before.md › Planning Docs Commit Gate: kept the approved plans in their own commit (eafa09b5) before any code, which made every later diff purely implementation. Retain.
RAILSPIKE.md › Key Rules ("a focused pass is never an unqualified full-suite result") with the host's "replay that condition or explicitly report it unverified": drove the baseline full-suite comparison per stage and running the http/https replay on main first. That run is what proved the harness faithful; an earlier version hid the bug behind Chrome's loopback treatment and the environment's proxy. Retain.
step4_implementation_do.md › Stage Boundary Protocol: committing per stage exposed two test-conversion mistakes in Stage 4 that a single end-of-cycle commit would have blended into the cutover. Retain.
Host AGENTS.md › Implementation standards ("For a reported user/environment failure, replay that condition or explicitly report it unverified"): kept the iPhone check pending rather than letting the Chromium replay stand in. Retain.

step4_implementation_after.md › Effort estimation and step4_implementation_do.md › Effort estimation repeat the retrospective/original/revision rules from effort-estimation.md. Suggest one link.
RAILSPIKE.md › Step 4 commit cadence lists the same "1 + stages" rule in three places (cadence, Key Rules, After checklist). Consolidate.

Stage split triggers written into a plan (Stage 4's "split if over about 150 lines") conflict with the rule that each stage commit leave a working state. Railspike does not say which wins; this cycle kept one commit and recorded the deviation. Suggest guidance that a split must itself leave each commit releasable.
Running the browser tests needed installing an already-declared dev dependency without changing manifests. The dependency rules cover adding/updating components but not installing declared ones locally for verification; the behavior seems allowed but is not stated.
