CHANGELOG

Workspace lab notebook for long-running or resumable research work.

2026-03-25 00:00 local — scaling-laws

• Objective: Set up a deep research workflow for scaling laws.
• Changed: Created plan artifact at outputs/.plans/scaling-laws.md; defined 4 disjoint researcher dimensions and acceptance criteria.
• Verified: Read CHANGELOG.md and checked prior memory for related plan scaling-laws-implications.
• Failed / learned: No prior run-specific changelog entries existed beyond the template.
• Blockers: Waiting for user confirmation before launching researcher round 1.
• Next: On confirmation, spawn 4 parallel researcher subagents and begin evidence collection.

2026-03-25 00:30 local — scaling-laws (T4 inference/time-scale pass)

• Objective: Complete T4 on inference/test-time scaling and reasoning-time compute, scoped to 2023–2026.
• Changed: Wrote notes/scaling-laws-research-inference.md; updated outputs/.plans/scaling-laws.md to mark T4 done and log the inference-scaling verification pass.
• Verified: Cross-read 13 primary/official sources covering Tree-of-Thoughts, PRMs, repeated sampling, compute-optimal test-time scaling, provable laws, o1, DeepSeek-R1, s1, verifier failures, Anthropic extended thinking, and OpenAI reasoning API docs.
• Failed / learned: OpenAI blog fetch for learning-to-reason-with-llms returned malformed content, so the note leans on the o1 system card and API docs instead of that blog post.
• Blockers: T2 and T5 remain open before final synthesis; no single unified law for inference-time scaling emerged from public sources.
• Next: Complete T5 implications synthesis, then reconcile T3/T4 with foundational T2 before drafting the cited brief.

2026-03-25 11:20 local — scaling-laws (T6 draft synthesis)

• Objective: Synthesize the four research notes into a single user-facing draft brief for the scaling-laws workflow.
• Changed: Wrote outputs/.drafts/scaling-laws-draft.md with an executive summary, curated reading list, qualitative meta-analysis, core-paper comparison table, explicit training-vs-inference distinction, and numbered inline citations with direct-URL sources.
• Verified: Cross-checked the draft against notes/scaling-laws-research-foundations.md, notes/scaling-laws-research-revisions.md, notes/scaling-laws-research-inference.md, and notes/scaling-laws-research-implications.md to ensure the brief explicitly states the literature is too heterogeneous for a pooled effect-size estimate.
• Failed / learned: The requested temp-run context.md and plan.md were absent, so the synthesis used outputs/.plans/scaling-laws.md plus the four note files as the working context.
• Blockers: Citation/claim verification pass still pending; this draft should be treated as pre-verification.
• Next: Run verifier/reviewer passes, then promote the draft into the final cited brief and provenance sidecar.

2026-03-25 11:28 local — scaling-laws (final brief + pdf)

• Objective: Deliver a paper guide and qualitative meta-analysis on AI scaling laws.
• Changed: Finalized outputs/scaling-laws.md and sidecar outputs/scaling-laws.provenance.md; rendered preview PDF at outputs/scaling-laws.pdf; updated plan ledger and verification log in outputs/.plans/scaling-laws.md.
• Verified: Ran a reviewer pass recorded in notes/scaling-laws-verification.md; spot-checked key primary papers via alpha-backed reads for Kaplan 2020, Chinchilla 2022, and Snell 2024; confirmed PDF render output exists.
• Failed / learned: A pooled statistical meta-analysis would be misleading because the literature mixes heterogeneous outcomes, scaling axes, and evaluation regimes; final deliverable uses a qualitative meta-analysis instead.
• Blockers: None for this brief.
• Next: If needed, extend into a narrower sub-survey (e.g. only pretraining laws, only inference-time scaling, or only post-Chinchilla data-quality revisions).

2026-03-25 14:52 local — skills-only-install

• Objective: Let users download the Feynman research skills without installing the full terminal runtime.
• Changed: Added standalone skills-only installers at scripts/install/install-skills.sh and scripts/install/install-skills.ps1; synced website-public copies; documented user-level and repo-local install flows in README.md, website/src/content/docs/getting-started/installation.md, and website/src/pages/index.astro.
• Verified: Ran sh -n scripts/install/install-skills.sh; ran node scripts/sync-website-installers.mjs; ran cd website && npm run build; executed sh scripts/install/install-skills.sh --dir <tmp> and confirmed extracted SKILL.md files land in the target directory.
• Failed / learned: PowerShell installer behavior was not executed locally because PowerShell is not installed in this environment.
• Blockers: None for the Unix installer flow; Windows remains syntax-only by inspection.
• Next: If users want this exposed more prominently, add a dedicated docs/reference page and a homepage-specific skills-only CTA instead of a text link.

2026-03-26 18:08 PDT — installer-release-unification

• Objective: Remove the moving edge installer channel and unify installs on tagged releases only.
• Changed: Updated scripts/install/install.sh, scripts/install/install.ps1, scripts/install/install-skills.sh, and scripts/install/install-skills.ps1 so the default target is the latest tagged release, latest-version resolution uses public GitHub release pages instead of api.github.com, and explicit edge requests now fail with a removal message; removed the release-edge job from .github/workflows/publish.yml; updated README.md and website/src/content/docs/getting-started/installation.md; re-synced website/public/install*.
• Verified: Ran sh -n on the Unix installer copies; confirmed sh scripts/install/install.sh edge and sh scripts/install/install-skills.sh edge --dir <tmp> fail with the intended removal message; executed sh scripts/install/install.sh into temp dirs and confirmed the installed binary reports 0.2.14; executed sh scripts/install/install-skills.sh --dir <tmp> and confirmed extracted SKILL.md files; ran cd website && npm run build.
• Failed / learned: The install failure was caused by unauthenticated GitHub API rate limiting on the edge path, so renaming channels without removing the API dependency would not have fixed the root cause.
• Blockers: npm run build still emits a pre-existing duplicate-content warning for getting-started/installation; the build succeeds.
• Next: If desired, remove the now-unused stable alias too and clean up the duplicate docs-content warning separately.

2026-03-27 11:58 PDT — release-0.2.15

• Objective: Make the non-Anthropic subagent/auth fixes and contributor-guide updates releasable to tagged-install users instead of leaving them only on main.
• Changed: Bumped the package version from 0.2.14 to 0.2.15 in package.json and package-lock.json; updated pinned installer examples in README.md and website/src/content/docs/getting-started/installation.md; aligned the local-development docs example to the npm-based root workflow; added CONTRIBUTING.md plus the bundled skills/contributing/SKILL.md.
• Verified: Confirmed the publish workflow keys off package.json versus the currently published npm version; confirmed local npm test, npm run typecheck, and npm run build pass before the release bump.
• Failed / learned: The open subagent issue is fixed on main but still user-visible on tagged installs until a fresh release is cut.
• Blockers: Need the GitHub publish workflow to finish successfully before the issue can be honestly closed as released.
• Next: Push 0.2.15, monitor the publish workflow, then update and close the relevant GitHub issue/PR once the release is live.
