The Middle of Your Context Is Rotting (Design It Away)
Companion to P-030 · the Green’s function of context: lost-in-the-middle is the impulse response of a kernel nobody designed, the dip has a closed form (2771 = 2771), uniform recall needs a register — it’s a theorem — and the cure is an inverse design problem that takes minutes of compute.
Agreement Has a Temperature
Companion to P-029 · the lock-in law: groupthink in agent collectives is a phase transition at K/T = 1 — one dial, one cliff, no useful middle. Four numbers you can compute before the first round, the diversity firewall that raises the threshold linearly, and the null result on the truncation folklore we actually tested.
The Agent Eats What You Don’t Pin
Companion to P-028 · the anchor law: the arithmetic for “how many tests before the agent is safe” — a maintenance floor that trades noise against frozen legacy error, a complexity ratchet your test suite can’t see, and the stability boundary that moves quadratically as models improve. Tests are contraction, not verification; budgets stop the ratchet.
Depth Pays Rent
Companion to P-027 · the dissipation budget law: every residual layer pays norm rent a normalizer refunds after the fact. Make transport a rotation, dissipation a meter, injection a port — and depth stability becomes a theorem with a budget line. Zero bound violations in 7,200 runs; the control explodes to 1043 — and rev 1.1 trains it end-to-end: baseline parity at depth 240 with no normalizer anywhere (97.3% ± 0.3 held-out).
Every Breach Is Every Breach
Companion to P-026 · the credential cascade: two channels, one concentration separatrix, and the doctrine that splits lockouts (defend everyone) from password managers (defend their users) — with the herd threshold that adoption can never reach.
The Queue That Wouldn’t Come Back
Companion to P-025 · the collapse law: the capacity ceiling no retry policy moves, the recovery threshold your retry budget feeds, and the two formulas that turn “shed load and restart” from folklore into arithmetic.
Your Build Breaks All at Once, Not Gradually
Companion to P-024 · resolution collapse: dependency hell is a phase transition with a computable threshold, version growth is fragility or slack depending on range policy, and failure feedback alone holds an ecosystem at its critical boundary.
Your Embeddings Are Photocopies of Photocopies
Companion to P-023 · generation loss: the drift law between encoder upgrades — rotations are mostly harmless in high dimension, distortion is the whole bill, and a landmark panel replaces the re-embedding calendar.
One-Timers Are Eating Your Cache, and the Fix Is a Formula
Companion to P-022 · the admission law: the closed-form door threshold, the capacity tax that prices bot traffic in slots, and why the folklore’s “tighter door” rule is backwards.
Your Dependencies Have an R₀. Nobody Computed It.
Companion to P-021 · the reproduction number of code: the spectral score everyone computes is exactly zero, the true threshold is one multiplication, and the registry yank has a two-step half-life.
Everything Works. Everything Shares One Fuse.
Companion to P-020 · blast radius engineering: one identity, one phone number, one cloud, one email reset path — your life has an org-chart of failure, and you’ve never seen it.
The Software You’ll Need in Ten Years Is Rotting in a Drawer
Companion to P-019 · dormancy engineering: the boot stick, the sealed firmware, the evidence kit — artifacts guaranteed to be exercised exactly when everything else has failed.
Your Data Has a Shelf Life. Nothing Tracks It.
Companion to P-018 · epistemic half-life: available, consistent, wrong — the failure mode no integrity constraint detects, and the half-lives already sitting in your change logs.
You Can Withdraw Anytime. The System Won’t.
Companion to P-017 · the revocation protocol: the most repeated promise in software is a local event with global ambitions, and the certificate ecosystem already wrote the fix.
Defaults Are Legislation Nobody Voted On
Companion to P-016 · the defaults ledger: organ donation at 4% or 99% between neighbors; $20B a year for one search box. The most powerful force in software has no records.
The Spreadsheet Lied to You. It Was Designed To.
Companion to P-015 · the uncertain document: every number in everyday software is a point estimate, and the fiction is expensive. The fix is a type.
Your Senses Have No Failover
Companion to P-014 · modality failover: storage has RAID, networks have multipath — and the one component guaranteed to fail nightly is wired with no backup.
Software Assumes You’re One Person. Half of Humanity Isn’t.
Companion to P-013 · delegated operation: 53 million caregivers operate someone else’s software through the worst architecture ever improvised.
Every Simplification Is a Relocation
Companion to P-012 · the complexity ledger: Tesler’s law is fifty years old, universally quoted, and measured by no one. That’s not a theory gap; it’s an accounting gap.
We Preserve Films and Seeds. Not Minds.
Companion to P-011 · model extinction: the fastest-dying artifact class on earth has no conservation institution — and the instruments can be built today.
xz Wasn't a Hack. It Was a Retirement.
Companion to P-010 · the bus factor protocol: the tired maintainer handed the keys to a stranger, and the registry had no model of any of it.
Your Calendar Was Designed for a Species That Doesn't Exist
Companion to P-009 · circadian orchestration: every calendar models availability; none models the four-to-six-hour spread of human chronotype.
The Company Died. Your Lights Didn't Get the Memo.
Companion to P-008 · the afterlife of devices: Insteon 2023, escrow since 1985, and the specification failure nobody has written down — until now.
You Don't Own Five Computers. You Own One Bad Computer.
Companion to P-007 · the intermittent compute fabric: the islands are real, the sea between them is drained, and the bridges are unbuilt.
The Most Important Scheduler in Computing Hasn't Been Written
Companion to P-006 · the attention scheduler: everything computers exist for gets scheduled except the thing they exist for.
Every File You Own Forgot Who It Is
Companion to P-005 · provenance-native storage: provenance was solved in 2006. Then nothing shipped. The AI era just made it mandatory.
Your Software Has a Second Behavior Nobody Wrote Down
Companion to P-004 · degradation contracts: there are two versions of every app — the one in the spec, and the one when the machine is tired.
Your Phone Sees Everything and Remembers Nothing
Companion to P-001 · the personal event bus: the missing skeleton of personal data infrastructure, and the organ that found it.
The Largest Unclaimed Money on Earth Is Yours
Companion to P-002 · consumer entitlements as dead capital: rights are invisible, perishable, and unpriced. That is a software problem.
Your Inflation Is Not the CPI
Companion to P-003 · the n=1 cost-of-living index: official inflation is an average over a nation that matches no individual — including you.
