Activity load performance — Railspike debug log

2026-10-27T22:40:15Z — Step 1

Mode: Enabled by host-root marker; recorded in Step 1.

Necessary/useful instructions

• Step 1 alternatives and approval boundary keep diagnosis/planning distinct from implementation. Retain.

• RAILSPIKE.md study exposure rules prevent inventing a pre-inspection estimate. Intake was missed; handoff is the first numeric snapshot. Retain.

• Step 1 concise assessment rule keeps options reviewable while detailed evidence lives in a linked investigation. Retain.

Redundant/unnecessary instructions

• No supported findings.

Inapplicable instructions

• Step 4 branch and stage commits are inapplicable to this requested Step 1; none performed.

Uncertain assessments

• Physical page length is ambiguous in Markdown with required study metadata. Assess rendered readability before a stricter interpretation; no workflow change proposed.

2026-10-27T22:57:57Z — Step 1 revision

Necessary/useful instructions: Step 1 review/revision and RAILSPIKE.md scope-history rules preserve the user's Forte refinement and original estimate without treating discussion as approval. Retain. Redundant/unnecessary instructions: No supported findings. Inapplicable instructions: Step 4 execution remains inapplicable. Uncertain assessments: Root cause remains unconfirmed; fast samples do not negate user evidence. No additional workflow change suggested.

2026-10-27T23:04:17Z — Step 1 direction revision

Necessary/useful instructions: Step 1 review/revision permits adopting the user's precomputation direction while preserving the original query and step gate. Extended-estimate scope history distinguishes narrowed C from earlier broad artifact work. Retain both. Redundant/unnecessary instructions: No supported findings. Inapplicable instructions: Implementation/stage commits remain inapplicable. Uncertain assessments: Existing incremental updater coverage is not yet audited; the 0.95 estimate includes recovery but may require a split at later planning. No workflow changes proposed.

2026-10-27T23:07:52Z — Step 2 handoff

Necessary/useful instructions: Step 2's named-environment requirement distinguishes zenmemes.com acceptance from local performance tests. Shared-surface inventory preserves RSS/full-commit/security contracts while changing both views. Recovery requirement covers interrupted indexing rather than only warm-read speed. Retain. Redundant/unnecessary instructions: No supported findings. Inapplicable instructions: Documentation-only restrictions do not apply to the proposed application change; implementation remains unapproved. Uncertain assessments: Concise requirements cannot establish updater coverage or production bottlenecks; Step 3 risk validation must resolve those rather than infer success from precomputation.

2026-10-27T23:15:13Z — Step 3 handoff

Necessary/useful instructions: Step 3 risk-first planning exposed direct Activity writers outside the primary updater and existing reusable signature results. Completion Contract keeps actual production acceptance separate from local verification. Extended stage estimates retain independent whole-cycle judgment. Retain. Redundant/unnecessary instructions: No supported findings. Inapplicable instructions: Documentation-only constraints do not apply; application execution remains gated. Uncertain assessments: Required seven-stage fields plus study/recovery evidence exceed a literal printed page; retained concise stage bullets and linked writer audit rather than dropping verification obligations. Stage sizing is provisional and must be revisited if updater fan-out demands broader work.

2026-10-28 — Step 4 completed-step report

Necessary/useful instructions:

• Step 4 stage-boundary commits preserved a reviewable chain: planning 2028f6d3a, S1 3e924f927, S2 d372c401a, S3 307cb5633, S4 bca0fa451, S5 e6ee91a5a, S6 1af723aca, S7 fd62cff90. Each stage includes verification and a summary update. Retain.

• Step 4 After's explicit production/known-user boundary prevents fast local HTTP tests from becoming an unsupported production-resolution claim. Deployment and actual user replay remain pending. Retain.

• Effort-study closeout rules preserve the 0.95 projection separately from 1.00 retrospective scope and unknown maintainer acceptance/active labor. Retain.

Redundant/unnecessary instructions:

• No supported findings.

Inapplicable instructions:

• Documentation-only execution restrictions were inapplicable to this approved application change. Dependency approval was not invoked because the actual addition/update inventory is zero.

Uncertain assessments:

• The nominal one-page/seven-stage planning constraint did not capture every mutation edge; source inspection and end-to-end regression tests found direct writers, prior provenance drift and legacy test assumptions. Keep the risk audit and allow evidence links rather than removing recovery requirements to fit page length.

• Single-run rebuild timings showed a genuine write-side tradeoff, improved by batching. They are not measured agent labor or a general deployment forecast; continued production evidence is necessary.

Final gate: Eight required planning/stage commits verified, clean working tree before this log-only report, no merge/deployment or accepted-count increment. Full suite and physical devices unverified; four reproduced baseline failures are identified in the implementation summary. No hidden diagnostics or uploads.
