ingest: Stanford SWEPR widening-gap study and AI-in-SDLC adoption pitfalls

Add two new sources with summaries, new concepts (developer-as-agent-manager,
review-is-the-new-bottleneck), new entities (SWEPR, Nikolai Sheiko), and a
query on the Stanford source; update related concept pages, overview, index,
and log.

 > **As the cost of writing code goes to zero, value migrates from *producing* software to *directing and verifying* it — and the durable human assets become judgment, ownership, taste, and in-person relationships.**
 
@@ -20,23 +20,24 @@ Everything else hangs off that:
 - **The human side** — what stays yours: [[product-ownership]] over outcomes, [[connections-as-moat|in-person connections]] as the last non-commoditized asset, [[seniority-and-the-junior-squeeze|judgment as risk-reduction]], and the need to [[decoupling-identity-from-profession|decouple identity from profession]].
 - **The strategy side** — where to point it: [[think-wider-not-bigger|think wider not bigger]], treat [[code-as-throwaway|code as throwaway]], and mind [[enterprise-ai-reality|enterprise compliance reality]] (the company-managed-harness market). Theo's second video supplies the *verifying* half of the spine its method: [[make-more-cheap-code]] — keep hand-verification of what ships, and generate orders of magnitude more never-shipped code to verify and explore.
 - **The frontier side** — what it looks like at the far end, from [[thorsten-ball]] at [[amp]] (99% of their code AI-written): [[shedding-weight|shed weight]] by deleting every process that only existed because humans were the bottleneck; [[build-for-the-agent-not-the-human|build for the agent, not the human]]; work [[async-by-default|async by default]] in remote sandboxes and ask for proof rather than claims. His two mechanisms for software becoming *personal* — [[emacsification-of-software|remixing what exists]] and [[explosion-of-internal-software|building what never did]] — are the corpus's strongest outside validation of the webinar's own thesis, "little tools you make for yourself." He is also its sharpest dissenter: he uses **no skills, no MCP, no slash commands**. Both mechanisms now carry a sourced counterweight — [[maintenance-is-the-real-cost]]: writing code was never the bottleneck, maintenance is, and an internal service is a second business. The reconciliation is a threshold, not a winner: tiny personal tools pass, replacing your Jira does not.
+- **The adoption side** — what goes wrong when organizations try this, from [[nikolai-sheiko]]'s multi-company casework ([[2026-07-30-rakes-in-ai-sdlc-adoption]]): the SDLC collapses *around the humans* — [[review-is-the-new-bottleneck|review becomes the bottleneck]] and volume metrics (LoC, PRs) go anti-informative, so measure **completed tasks without rework**; the developer's job flips from CPU-bound coding to [[developer-as-agent-manager|IO-bound agent management]]; and the winning company move is not custom AI development but installing and *evolving* a standard harness ([[enterprise-ai-reality]]) — with skills grown by walking the agent through real tasks and verified by a context-free subagent ([[solve-first-then-skillify]]).
 - **The demand side** — three interviews ground it all in a real audience. The two HR ones ([[2026-07-14-nina-interview|Nina]], [[2026-07-14-yulia-interview|Yulia]]) supply pain points (interview write-ups, job descriptions, sourcing) that collapse into "a candidate knowledge base plus search," teachable via [[levels-of-ai-usage]] and [[solve-first-then-skillify]]. Their key finding: **adoption is blocked by friction, not resistance.** The [[2026-07-21-larysa-interview|Larysa interview]] adds the *advanced* user's version of the same story: past the friction, the remaining walls are structural — no durable memory, [[integration-dead-ends|integrations that dead-end]], and drift on loose specs ([[leave-less-room-for-imagination]]). Her diagnosis matters because she is technically deep yet skipped the skills rung, which is exactly what her "the agent forgot" complaint reduces to.

 ## Where sources agree vs diverge
 
-- **Agree:** code is cheap/disposable; harnesses are the unit of work; skills-as-memory (Konstantin ↔ Allie ↔ Eugene); human relationships rise in value (Sebastian ↔ Allie ↔ Eugene, who lands there independently in the Yulia interview); solve-first-then-skillify (Eugene ↔ Konstantin's heuristics); context is the constraint — Thorsten's version is the bluntest: **the dominant variable in output quality is the information you put in**, not the model or the effort level. The [[2026-07-22-ai-is-stupid|"AI is stupid!" short]] independently compresses the machine-side spine into a business one-liner: **model + context + harness = employee-level answer**. Slop is a human problem, not an AI defect (Theo ↔ Thorsten, from verification discipline and from taste respectively). Software becomes personal — "little tools you make for yourself" (Eugene's webinar arc ↔ Thorsten's club app and bespoke forks ↔ Allie's personal OS).
-- **Diverge:** personal vs company-managed vs vendor-managed harness ([[eugene]] vs [[sebastian]] vs [[amp]]); online vs in-person networking (Eugene/Sebastian); OSS as marketing vs OSS growth; built-in agent memory as anti-feature (Eugene) vs persistent context docs used without complaint (Allie); tight specs ([[leave-less-room-for-imagination]]) vs wide latitude ([[think-wider-not-bigger]]); agent diff-summaries as sufficient review (Theo/Dax) vs invisible drift as the core danger (Eugene); model choice as a real lever (Eugene runs 4.7 over 4.8) vs a distraction past the frontier (Thorsten); local consolidated workspace (Eugene) vs local dev disappearing into remote sandboxes (Thorsten); build-your-own-tools ([[thorsten-ball]], the webinar arc) vs [[maintenance-is-the-real-cost|buy anything that needs ongoing support]] (the vibe-coding video, with the corpus's only observed reversal: an in-house Jira clone abandoned for Linear in four months). These live under "Contradictions" on the relevant pages.
-- **The one that matters most for the webinar:** [[thorsten-ball]] runs a 99%-AI-written codebase with **no skills, no MCP servers and no slash commands** — his context lives in the codebase and `AGENTS.md`. That is the corpus's first credible rejection of the mechanism the webinar's central promise rests on. Three readings (situational / premature abstraction / same thing under another name) are logged on [[skills-as-memory]]; none is settled, and the evidential asymmetry favours him — his is first-hand daily practice at scale.

And the corpus's central *stakes* claim now has outside measurement: [[2026-07-30-stanford-swepr-widening-gap|Stanford SWEPR]] finds the productivity gap between AI-mastering and lagging teams grew 4.8% → 19% (4×) from April 2023 to July 2025 — Allie's prediction, measured; the same study's codebase-size finding independently supports [[context-as-scarce-resource|context as the binding constraint]]. [[2026-07-30-rakes-in-ai-sdlc-adoption|Sheiko]] cites that same Stanford chart as his stakes slide and lands on the spine independently — "companies no longer need custom AI development, install Claude Code or Codex and configure it" is harness-over-model as a service playbook, and his codebase-stores-context prescription converges with Thorsten's from the opposite direction. His review-bottleneck casework (+1% net despite more PRs) is SWEPR's +91%-review-time finding told anecdotally.
