PORTAL_Computation - Wikiparency

# PORTAL: Computation > **Permissions to request up front (house rule, MTN 2026-09-22).** Any agent that works this page — its spine, the worklists at its foot, or its shard — states before its first tool call every permission the run will need and asks for all of them in one round: (1) browser-pane site access, scope *site*: en.wikipedia.org (title and oldid verification), wikitube-3d-microsims.netlify.app (200-checks of players), cdn.jsdelivr.net (library pins), and gutenberg.org / archive.org / ntrs.nasa.gov only if a book is re-fetched; (2) folder access to the vault root (`en.wikitube.io/`) and, for a deploy pass, to `_3d_deploy_stage/`; (3) no `WT!` authorization is needed for this page — it is an ordinary portal — but touching `WT!Space_Mining_In_Minnesota` or its `PORTAL_WT!` page needs MTN's (WIKI_RULES §1, §11); (4) no delete permission — everything here is append-only; (5) production deploy is MTN's: the run stages into `_3d_deploy_stage/<set>/` and hands over the deploy script. Nothing else. **Computation** — the mathematics every microsim on the wiki runs — quantity, relation, solve, integrate, estimate, optimise, decide — with the Space Mining spine as its first customer and every other portal as the next. It is the megalith: it ties the seven lesser portals together and runs through the entire wiki, so every row here names the apex sections it serves, and the seven sibling portals reach it through their Crosslinks. Thirty sections in six parts, thirty Main articles, one three.js microsim per section, and one hero: **The Computation Line**, an instance of the Master Portal Hero. Index: [[PORTAL_INDEX]] · apex: [[PORTAL_WT!Space_Mining_In_Minnesota]] · hub: [[PORTAL_Centers_of_Excellence]]. **On the spine:** [[PORTAL_WT!Space_Mining_In_Minnesota]] · [[WT!Space_Mining_In_Minnesota]] · the siblings in service (Crosslinks) · hub [[PORTAL_Centers_of_Excellence]]. ## How to read this page The Spine table is the map: one row per section, with the article, the microsim it plays and its build state. The six parts follow as a skeletal outline — one line per section with the sim brief, the equation and the apex sections it serves — for the models that will populate the child articles. Then the shelf, the crosslinks (siblings, the History, Lists and Glossaries of the field), the notes, the gallery, and at the foot the two worklists — the Microsim Worklist and the Article Worklist — in the house row grammar.  <div class="wt-sim" data-src="https://wikitube-3d-microsims.netlify.app/computation/Computation_Line.html" data-title="The Computation Line"></div>  *The Computation Line (CMP-HERO, `computation/Computation_Line.html`, built and gated SHIP 2026-09-22, 36 URL states walked headless with an empty console; the player goes live with MTN's next production publish): one problem from each of five portals walked through measure, model, solve, integrate, estimate, optimise, decide; the uncertainty of the answer walks the chain, the bars count the arithmetic. Every section below is a stage or a component of it, and a child article embeds the hero locked on its own state (`?body=<id>&stage=<id>&embed=1`) until its section sim ships.* ## Spine | # | Article | Reveal | Microsim | Node | |---|---|---|---|---| | ⊙ | [[PORTAL_Computation]] | three | `computation/Computation_Line.html` — The Computation Line, 36 URL states (`?body=&stage=&embed=1`); **built, SHIP** 2026-09-22, awaiting publish | CMP-HERO | | | **Part I — Quantity: number, measure and figure** | | | | | 1 | [[Measurement_uncertainty]] | three | `computation/Measurement_uncertainty.html` — queued (row CMP-001) | CMP-001 | | 2 | [[Proportionality_(mathematics)]] | three | `computation/Proportionality_(mathematics).html` — queued (row CMP-002) | CMP-002 | | 3 | [[Dimensional_analysis]] | three | `computation/Dimensional_analysis.html` — queued (row CMP-003) | CMP-003 | | 4 | [[Logarithm]] | three | `computation/Logarithm.html` — queued (row CMP-004) | CMP-004 | | 5 | [[Euclidean_geometry]] | three | `computation/Euclidean_geometry.html` — queued (row CMP-005) | CMP-005 | | | **Part II — Relation: the functions the sims run** | | | | | 6 | [[Mathematical_model]] | three | `computation/Mathematical_model.html` — queued (row CMP-006) | CMP-006 | | 7 | [[Exponential_growth]] | three | `computation/Exponential_growth.html` — queued (row CMP-007) | CMP-007 | | 8 | [[Power_law]] | three | `computation/Power_law.html` — queued (row CMP-008) | CMP-008 | | 9 | [[Geometric_series]] | three | `computation/Geometric_series.html` — queued (row CMP-009) | CMP-009 | | 10 | [[Conic_section]] | three | `computation/Conic_section.html` — queued (row CMP-010) | CMP-010 | | | **Part III — Solve: algebra and linear systems** | | | | | 11 | [[System_of_linear_equations]] | three | `computation/System_of_linear_equations.html` — queued (row CMP-011) | CMP-011 | | 12 | [[Matrix_(mathematics)]] | three | `computation/Matrix_(mathematics).html` — queued (row CMP-012) | CMP-012 | | 13 | [[Eigenvalues_and_eigenvectors]] | three | `computation/Eigenvalues_and_eigenvectors.html` — queued (row CMP-013) | CMP-013 | | 14 | [[Least_squares]] | three | `computation/Least_squares.html` — queued (row CMP-014) | CMP-014 | | 15 | [[Newton's_method]] | three | `computation/Newton's_method.html` — queued (row CMP-015) | CMP-015 | | | **Part IV — Integrate: calculus and the numerics of motion** | | | | | 16 | [[Derivative]] | three | `computation/Derivative.html` — queued (row CMP-016) | CMP-016 | | 17 | [[Integral]] | three | `computation/Integral.html` — queued (row CMP-017) | CMP-017 | | 18 | [[Ordinary_differential_equation]] | three | `computation/Ordinary_differential_equation.html` — queued (row CMP-018) | CMP-018 | | 19 | [[Euler_method]] | three | `computation/Euler_method.html` — queued (row CMP-019) | CMP-019 | | 20 | [[Runge–Kutta_methods]] | three | `computation/Runge–Kutta_methods.html` — queued (row CMP-020) | CMP-020 | | | **Part V — Estimate: probability and statistics** | | | | | 21 | [[Variance]] | three | `computation/Variance.html` — queued (row CMP-021) | CMP-021 | | 22 | [[Sampling_(statistics)]] | three | `computation/Sampling_(statistics).html` — queued (row CMP-022) | CMP-022 | | 23 | [[Normal_distribution]] | three | `computation/Normal_distribution.html` — queued (row CMP-023) | CMP-023 | | 24 | [[Monte_Carlo_method]] | three | `computation/Monte_Carlo_method.html` — queued (row CMP-024) | CMP-024 | | 25 | [[Kriging]] | three | the apex's `spacemining/Kriging.html` (SMM-012; in the apex queue) — membership, not a second build | CMP-025 | | | **Part VI — Optimise and decide: extremes, logic and machines** | | | | | 26 | [[Mathematical_optimization]] | three | `computation/Mathematical_optimization.html` — queued (row CMP-026) | CMP-026 | | 27 | [[Inequality_(mathematics)]] | three | `computation/Inequality_(mathematics).html` — queued (row CMP-027) | CMP-027 | | 28 | [[Boolean_algebra]] | three | `computation/Boolean_algebra.html` — queued (row CMP-028) | CMP-028 | | 29 | [[Algorithm]] | three | `computation/Algorithm.html` — queued (row CMP-029) | CMP-029 | | 30 | [[Cellular_automaton]] | three | `computation/Cellular_automaton.html` — queued (row CMP-030) | CMP-030 | ## The six parts (skeletal outline) ### Part I — Quantity: number, measure and figure 1. **Measurement uncertainty** — *Main article: [[Measurement_uncertainty]] · See also: [[Accuracy_and_precision]], [[Significant_figures]], [[Propagation_of_uncertainty]], [[Order_of_magnitude]].* A measured grade with error bars: slide the assay count and read how the uncertainty of the mean falls as 1/sqrt(n) — `u(mean) = s / sqrt(n)` (the arithmetic of error).

It is a skeletal outline by design (MTN, 2026-09-22): less advanced models populate the child articles and their sims from the two worklists at the foot, with the hero as the model of the house pattern. 2. **Slugs.** Every article slug is the exact current English Wikipedia title, resolved through the API on 2026-09-22 (redirects followed to their targets, disambiguation and non-existent titles dropped before the spine was fixed); `rev:` on every worklist row pins the revision. 3. **Build state.** The hero `computation/Computation_Line.html` is built and gated SHIP (rendered, zero console, sweep clean, 11 draw calls; `tools/gate.sh`, 2026-09-22) and its 36 URL states were walked headless; it is staged, not deployed — production is MTN's (style guide §12.10: a player replaces a placeholder only after a 200-check). Of the thirty section sims, 0 reuse a player a portal page already carries (none), 1 reuses the apex spine's (SMM-012), and the other 29 are queued as specs of their own. 4. **One article, several portals.** A section whose Main article is also an apex Main article is a *reuse* row: the apex owns the article and the sim, this portal adds membership (shared contract §1); the same holds for See-also titles the apex already carries. Available reads 0 on this page for the same reason as on the apex: nothing is verified live yet. 5. **The megalith.** Computation runs through the entire wiki: every *Computation:* line on the apex flagship names a section here (the plan's §6 map), and the reviewer's 25 briefs (BOOK_REVIEW.md) sit at the foot as Priority C with their page-and-line locators in Boole, Hilbert, Euclid, Hatcher, Russell, Levin and Perelman. Registry id: the rulebook package calls this portal `PORTAL_Compute`; this wiki files it as `PORTAL_Computation` with that id as its alias. 6. **Worklist mechanics.** Rows are claimed, heart-beaten and closed only through the queue tool on the shard (`Style Guide and Worklist/PORTAL_Computation.worklist.md`); a row turns ✅ only with a live URL. The two lists here, the shard and `worklists/PORTAL_Computation/jobs.json` are projections of one record, regenerated together by `build_portals9.py` (kept with the item-9 checkpoint).  ## Play every microsim on this page <p class="microsim-gallery-note">Every microsim linked from this portal's in-service spine. <strong>1 player</strong> — 1 threejs.

Examined: every title against the English Wikipedia API on 2026-09-22 (redirects followed, missing and disambiguation titles dropped before the spine was fixed), the apex spine's rows (for shared articles), the three existing portal pages (for players already carried), the framework's `specs/sims/` (the hero built) and the run's book shelf.

Every article follows style guide §2–§6 and §13: slug = the verified Wikipedia title, `oldid` pinned to `rev:`, the H2 skeleton mirrored from that revision, a lead that defines in bold and names the microsim, every figure footnoted to the shelf, a `Wikipedia : Wikitube` section, and a registry row. `WT!` pages sit outside this list. ### Article To Do #### Priority A — Main articles (30) -
