What your 86 rulings had in common, and what is being done about it across Grade 5

Status: written 9 October 2026, 13:30, from your rulings on Topics 1–7, 11, 12, 15, 20, 24 and 25. Evidence table with every ruling verbatim: grade5/records/SYSTEMIC_ISSUES_EVIDENCE_2026-10-09.md.

The takeaways. Three faults are truly systemic and all three are now caught by a machine before a topic ships: a coined term swapped for other words, vague titles and vague references, and loose numbers. Three more are habits of the writer that a reader has to catch, and the 21 topics you have not reviewed are getting that read today before their videos go. Nothing you found means a topic was teaching the wrong science; every fix is to words, drawings and the order things are said. Of the 86 rulings, 40 were a plain Fine, and seven lessons you praised are going forward as golden candidates.

The three systemic faults, and the machine that now catches each

1. A coined term swapped for other words. Your words: "why are you changing a coined term? Never do this … once a required technical science term is coined and introduced, it should be used from then onwards" (Topic 2); "stuff = matter — weird that you keep making this mistake, probably a root cause that needs to be fixed" (Topic 25).

• How often: 2 of your 13 topics, but the sweep found bare "stuff" in 12 topics and "young one" for Grade 3's "offspring" in two more.
• Root cause, found: Topic 2's author read TEKS 5.7A ("equal and unequal forces") and coined those words on purpose, listing Grade 3's balanced / unbalanced as the old synonym. Two rules collided: "use the standards' term" and "a coined term is used from then on". The vault now says the earlier coined term wins. The "stuff" cases are a different slip: writers took your 25 September rule ("say stuff beside matter") as licence to say "stuff" alone.
• The fix across Grade 5: a new check (S48) fails any topic where a coined term's shadow phrase appears after the coining. It runs on every topic before its batch goes. Topics 2, 3, 11, 12, 25 and 28 are at zero; the 21 unreviewed topics are being swept to zero now.

2. Vague titles and vague references. Your words: "quite a few lesson titles like this should be made more specific"; "none of the change — exactly the kind of contracted abstract wording we should be avoiding" (Topic 24); "'so the globe stands in' — that's the kind of dodgy vague wording" (Topic 20); "the energy that the circuit gives out" (Topic 6); "anyway → under normal conditions".

• How often: 6 of your 13 topics, 10 rulings. The sweep finds the same markers in Topics 20 and 24 above all (133 and 72 lines) and a handful in most others.
• The fix: titles and references name the thing. A model is introduced in your shape ("Earth is too big to see at once, so we look at a globe instead"). A sweep for the marker phrases runs on every topic; the deploy session has been asked to add it to the gate.

3. Loose numbers. Your words: "don't compare grams with kilograms"; "don't use a comma for thousands, use a space — that is a general rule, cos a comma looks like a decimal place" (Topic 24); "where did the 92 cm come from? … the numbers are not making sense" (Topic 3).

• How often: 3 of your 13 topics. The sweep finds comma thousands in Topic 8 and mixed units in Topics 5, 8 and 24.
• The fix: a space for thousands, one unit through a comparison, one set of numbers per lesson. Mechanical for the first two; the third is a reader's check on every lesson that tells a chain of events.

Three habits a reader has to catch

4. Questions and asides that do no work. "stupid question → delete"; "delete the non-example, not helpful in this case" (Topic 1); "the initial question is silly" (Topic 6); "Every field, pond and forest grows again the same way — delete" (Topic 25). Five topics, seven rulings. The test the readers now apply: a question the narrator answers in one word, or a non-example that does not sharpen the rule, goes.

5. Endings. A closing statement should be open and active ("When we use a battery or fuel, its chemical energy ends up as another form of energy. For example, that might be kinetic energy in a thing that moves, or thermal energy in a thing that warms up"); a lesson that ends on a rule needs its conclusion ("so here's what we've seen …"); a summary may reorder the rule lines "in the rare cases" where that keeps related things in one sentence. Four topics each. The write-summary and write-video-script skills now carry these; every unreviewed script's last beat is being read against them.

6. The thing being taught drifts. The lesson that should keep the push the same varied the push (Topic 2); the mass-and-kinetic-energy idea had no Grade 5 standard behind it (Topic 5, now removed); a fair-test lesson had no clean example sequence (Topic 3, now built in your five cases). One each, but the same shape: the writer added a true thing that was not the lesson's thing. The check is the atom and its standard code, recorded per lesson, and the design-check-sequence step before any classification lesson.

Smaller, settled today

• Earth is a sphere, never "a ball" (three rulings; the sweep found real "ball" wording for planets in Topics 16, 21 and 22, being fixed).
• A term is never used before the topic that coins it: "solution" and "decomposer" both turned out to be Grade 4 coinings, so no fault, but no course-wide check existed; one is requested.
• Static electricity is the topic's name; non-contact forces and the electric force are coined where you said.
• The circuit lesson moves from Topic 7 to end Topic 6, as you asked.
• On-screen text: your Grade 4 ruling this morning ("bullet points only") applies to Grade 5's briefs; every unsent batch is rebuilt so the rule is spoken and never printed.

What you praised

"Great lesson!" on Topic 5 L05, Topic 15 L06 and Topic 20 L04 ("really good use of an analogy"), "another great lesson" on Topic 20 L06, "great intro" on Topic 24, "perfect, well done!" on Topic 7 L02's term-then-recap, and "what you've done as a general principle here is great" on Topic 4 L02's what-before-why. These seven are nominated as golden examples for their lesson types; the Second Brain session has the list.

Where the build stands and what happens next

• The 13 topics you reviewed: your rulings applied, every changed item re-read cold. Topics 1, 2, 4, 5 and 11 are rendering (31 videos in flight). Topics 3, 6, 7, 12, 15, 20, 24 and 25 follow today as each clears.
• The 21 topics you have not reviewed: four agents are sweeping them now for the six faults above, as text, before their videos go. Their batches are built and go the moment each topic is at zero.
• The four strand tests are being authored fresh (Grade 3's shape); the end-of-grade test follows them.
• One page of rulings for you is coming, capped at ten cards.
