memory(detect-changes pattern): sibling-repo parallel-optimized external anchor (Aaron 2026-05-01) by AceHack · Pull Request #1130 · Lucent-Financial-Group/Zeta

AceHack · 2026-05-01T17:51:10Z

Summary

Aaron 2026-05-01: "../no-copy-only-learning-agents-insight is the best repo in github i've seen setup to be parallel."

Direct inspection (DST grade-A pull-to-sibling-repo + gh-api-on-host disciplines) revealed seven load-bearing parallel-optimization patterns. Memory file captures them as substrate; company name redacted per the no-copy-only-learning principle.

Patterns captured

detect-changes.yaml workflow emitting per-change-class outputs — PRs only run relevant workflows
42 fine-grained workflows (vs our ~15 monolithic)
Test parallelism at script level (bash + PS1 pair)
5 concern-aligned rulesets — empirically validates B-0155 architecture
Branch protection effectively empty (zero contexts, all migrated to rulesets) — empirical proof B-0155 Phase 3 cleanup endpoint works at production scale
Sibling repo uses Wiki not Pages — Aaron's prior Jekyll-on-Pages was workaround, not preference ("bun is probably enough")
AGENTS.md learning-discipline — convergence with our existing patterns (lessons-in-PR / joint-learning / source-investigation / search-first authority)

Attribution

The sibling repo's host config is deliberate-by-others (multi-engineer org-scale design); Zeta is Aaron-clicked-alone. High-credibility external anchor for design patterns we extract. Sharpens the click-vs-decision distinction across actors.

Carved candidate

"The detect-changes pattern is the parallel-PR primitive. Without it, every PR contests for every check. With it, PRs that touch different concerns don't see each other."

composes_with

B-0153 (lint suite) + B-0154 (Pages + Wiki) + B-0155 (ruleset-split) + B-0156 (TS port) + Otto-235 (4-bash + PS) + task #305 (install.ps1) + task #341 (TS migration) + Otto-352 (external-anchor-lineage)

Test plan

markdownlint clean
MEMORY.md paired-edit included in same PR
Company-internal names redacted to placeholders (`/`)
memory-edge schema used (composes_with + caused_by)

Pull request overview

Adds a new memory entry capturing a “detect-changes workflow + fine-grained workflow split” CI parallelization pattern observed in a sibling repository, and updates the memory index to reference it (plus related redaction updates).

Changes:

Added a new memory file documenting the external “detect-changes” CI pattern and how it composes with existing Zeta backlog/ruleset work.
Updated memory/MEMORY.md to include the new entry and to replace several existing index entries with redacted “sibling org” placeholders.

File	Description
memory/feedback_detect_changes_pattern_sibling_repo_parallel_optimized_external_anchor_aaron_2026_05_01.md	New memory entry documenting CI parallelization patterns and rollout guidance.
memory/MEMORY.md	Adds an index entry for the new memory and updates multiple existing index links/labels.

… new content only (Aaron 2026-05-01) Aaron 2026-05-01 calibration: *"../it's folder name was fine"* + *"that's why i named it that."* The `../no-copy-only-learning-agents-insight` directory name IS the abstraction discipline Aaron designed. New substrate uses generic placeholders (`<sibling-org>/<sibling-repo>`); existing filenames with company names are GRANDFATHERED per the established naming + scope-of-org-access rule (2026-04-28). My prior commit's `<sibling-org>` substitution was over- aggressive — it broke valid existing MEMORY.md link targets to real files (feedback_servicetitan_naming_*, project_account_setup_snapshot_codex_servicetitan_*, project_frontier_burn_rate_ui_*_servicetitan_*, feedback_servicetitan_demo_*, etc.). The link TEXT was already redacted to "the sibling-repo external anchor" / generic phrasing; the link TARGETS need to point at real files. Restored link targets to the real filenames. New content (memory body + MEMORY.md link text) keeps the redacted phrasing per the no-copy-only-learning principle for new substrate. Resolves PR #1130 review threads PRRT_kwDOSF9kNM5_BSNv + PRRT_kwDOSF9kNM5_BSNx.

…ect-changes memory Per the no-copy-only-learning principle (the directory is named `../no-copy-only-learning-agents-insight` for exactly this reason): extract patterns/insights, not company-internal names. Renamed file: feedback_detect_changes_pattern_stcrm_* → feedback_detect_changes_pattern_sibling_repo_* Replaced all in-body references to STCRM / servicetitan / stcrm with "the sibling repo" / "<sibling-org>/<sibling-repo>" placeholders. Cleaned up double-mentions from automated sed pass. The patterns + architectural insights are preserved. The company name is gone. Note: prior commit message + PR title still leak the name (history already on origin); fixing forward only.
