ui_shell_navigation debug log
Railspike debug reports for cycle v3/ui_shell_navigation. Debug mode was enabled from the project marker .railspike_debug_on at cycle start.
2026-10-27T03:38:05Z — Step 1 (Solution Assessment) handoff
Necessary/useful instructions
RAILSPIKE.md, "Choose the execution mode": the user's checklist pre-selected staged mode for this cycle; the section confirmed that a mode label is not execution authorization, so implementation questions stayed out of Step 1. Retain.step1_solution_assessment.md, "Structure" (Original Query preserved verbatim, optional Understood Intent): the query was two words ("Begin Cycle 1"), so Understood Intent was needed to link the checklist cycle without inventing scope. Retain.RAILSPIKE.md, "Experimental Effort Estimation", intake checkpoint ("Preserve initial scoped estimate ... before detailed implementation inspection"): forced the intake score to be written before reading the shell code, which made the later 0.90 → 0.85 change attributable to new understanding. Retain.RAILSPIKE.md, "Extended estimates" precedence (explicit override → cycle state → host policy → new-cycle default): resolved cleanly to enabled, since P2 says nothing about extended mode. Retain.RAILSPIKE.md, "Agent attribution", verified-metadata rule: the model ID was available from session metadata; reasoning effort was not explicitly verified and was omitted. Retain.
Redundant/unnecessary instructions
step1_solution_assessment.md, "Effort estimation" paragraph repeats most of the extended-estimate rules already inRAILSPIKE.md. Observable overhead: the same rules read twice in one step. Suggestion: consolidate to a one-line pointer plus the Step 1-specific requirement (every option estimated).
Inapplicable instructions
RAILSPIKE.md, "Repository Boundary" paragraph onrailspike-dev: this host is not Railspike itself.One-shot workflow and transition rules: this cycle is staged.
Frozen-reference recovery procedure: R1 snapshots were present and hashes matched, so no recovery was needed.
Uncertain assessments
The ≤1 page limit versus the required effort-study table and constraint list: the artifact is close to one page with the study table; unclear whether study metadata counts toward the page limit.
Whether the host ledger's long prose paragraphs per checkpoint (an established convention in
effort_estimation_trial.md) are required, or whether the index row plus a link would suffice under P2.
2026-10-27T04:18:58Z — Step 2 (Feature Description) handoff
Necessary/useful instructions
step2_feature_description.md, "Shared component inventory" ("enumerate every existing UI/API surface that already renders the data"): led to inspecting the scripts that read the nav (feature_flags.js,private_message_unread.js,auth_navigation.js,offline_reader.js), which surfaced the "scripts assume today's nav" risk before planning. Retain.step2_feature_description.md, "Completion boundary" (normal entry, outcome, recovery, release condition): made the no-JavaScript and switch-back recovery paths explicit requirements rather than assumptions. Retain.step2_feature_description.md, "Risks" (impact, earliest validation, mitigation): produced concrete early validations (theme skeleton render, script trace, phone check on thread and compose pages) that Step 3 can order first. Retain.
Redundant/unnecessary instructions
step2_feature_description.md, "Effort estimation" again restates extended-estimate inheritance and estimate presentation already inRAILSPIKE.md. Observable overhead: re-reading the same rules each step. Suggestion: consolidate into one pointer.
Inapplicable instructions
"Known user or environment": the request names no user, machine or environment, so the item is omitted.
Documentation-only scope fields: this is an application change.
Uncertain assessments
The ≤1 page target versus the required sections (stories, requirements, scope, boundary, risks, inventory, flow, criteria) plus the study checkpoint: this artifact runs past one page; unclear whether the limit is meant to be strict for UI shell work with many existing surfaces.
2026-10-27T04:23:38Z — Step 3 (Development Plan) handoff
Necessary/useful instructions
step3_development_plan_after.md, checklist item 2 ("Verify stage sizing is still atomic (about <=1 hour per stage) and split oversized stages before review"): caught three oversized stages in the first draft (markup plus styles, all themes plus icon themes); splitting produced eight reviewable stages. Retain.step3_development_plan_do.md,## Key Riskswith**High risk:**prefixes for usability and rollback: the two high risks (unreachable destinations, failed switch-back) became Stage 1 tests, ahead of any UI work. Retain.step3_development_plan_do.md, Completion Contract "deployment/external verification": prompted checking the theme guide, which surfaced the baked-artifact rebuild that production also needs. Retain.step2_feature_description.mdrisk "earliest validation" carried into Step 3: tracingfeature_flags.jsandprivate_message_unread.jsbefore planning changed the design to a single nav element placed by CSS, avoiding duplicated IDs. Retain.
Redundant/unnecessary instructions
step3_development_plan_do.mdandstep3_development_plan_after.mdboth restate the single-footer attribution rule in near-identical words. Observable overhead: reading the same rule twice within one step. Suggestion: keep it in the do-phase file and reference it from the checklist.
Inapplicable instructions
Known user/environment replay stage: Step 2 names no user or environment.
Documentation-only Completion Contract variant: application change.
Database change notes: no schema or read-model change.
Uncertain assessments
"Numbered plan (<=1 page)" versus eight stages each requiring six fields plus estimate lines: the plan is well over one page. The stage-field requirements and the page limit appear to conflict for an eight-stage plan.
"Stages should be about <=1 hour or <=50 lines of change": Stage 4 (phone tab bar) and Stage 6 (13-theme pass) may still exceed an hour of agent time; they were judged indivisible without creating layer-only stages.
2026-10-27 — Step 4 (Implementation) completed-step report
Necessary/useful instructions
step4_implementation_after.md, item 7 ("A focused pass is never reported as a full-suite or user-outcome result"): the full suite was stopped at 712 of about 1,417 tests and is recorded as partial, with the untested remainder named. Retain.step4_implementation_after.md, item 7, "Identify reproduced baseline failures": separating baseline failures from cycle regressions (Stage 2 baseline worktree, Stage 8 test history) kept stale tests from being read as shell regressions. Retain.Commit cadence ("each completed stage must be committed with its Step 4 summary update"): the Stage 4 false pass was found and corrected in its own commit without amending; the summary keeps both the wrong claim and the correction. Retain.
Redundant/unnecessary instructions
None observed that cost measurable time in this step.
Inapplicable instructions
Documentation-only verification variant: application change.
Database and read-model schema notes: no schema change.
Deployment verification: production deploy outside approved scope; recorded as unverified.
Uncertain assessments
Full-suite expectation versus suite cost: on this branch every static build renders all platform docs pages, so the suite exceeds an hour. Workflow text does not say whether a partial run plus a post-merge full run satisfies Step 4; treated here as partial with the full run deferred to the merge follow-up.
Editing tracked docs while the suite runs makes
ImportedContentPublicationTestfail ("Documentation changed during publication"). Workflow does not warn about this; an agent writing the summary during verification will hit it.Fixing pre-existing failing tests within the final stage: recorded as corrective work; unclear whether the workflow prefers a separate cycle for this.
