needs approval DIAGRAM REWRITE (2026-08-15): the payload was a bottleneck diagram, many tapering streams converging through a moulded neck and degrading below it. Killed on feasibility, not on argument: we have no manpower or vector skill for a custom-drawn form, and that shape does not exist on Canva as a labelable element. Replaced with an hourglass, which is a stock shape, argues the same throttle by its own form, and is buildable from two triangles and a bridge if no element is found. The standing rule now lives in docs/visual-design-language.md ("Feasibility: is it doable on Canva?") and is echoed in the carousel, single-post, and social-post guides and in all three skills., DESIGN SESSION (2026-08-15): hourglass built in Affinity by Twin, capped form, Gray Azure body with a Dark Azure facet, neutral grey sand equal in both chambers, and an `#E30621` band at the neck as the single accent. Kicker dropped. Layout is shape-left with a single right-hand label column. The palette gained the azure secondaries the same day, recorded in docs/visual-design-language.md; azure as a full page ground is still an open question for Twin., METAPHOR SEPARATION from week 1. Week 1 owned the glass: a container, argued on volume, how much it holds. The hourglass here is argued on RATE, how fast one narrow point lets things through. Keep all label copy on passage and pace. Never write that the hourglass holds, fills, or overflows, or the post quietly re-makes week 1's point with a new shape., LANGUAGE REWRITE (2026-08-15): all copy on this post was rewritten against the four concreteness tests in docs/social-posts-guide.md ("Write it plain"), after Dr. Lyra returned week 2's carousel for being too abstract. The previous version leaned on "a transformation", "that capacity", "everything downstream" and "the binding limit", none of which a chief can picture., TERM DECISION (Twin, 2026-08-15): "Brain Capacity" appears on the card and in both captions, per the decision to run the term through the month rather than confine it to week 1. The card names it and the caption defines it, which the single-posts guide permits. IP status is still unresolved: see the same flag in post-1.md. This post claims only that the term is ours to measure, not that we coined the phrase, so it stands either way., PERSON SHIFT is deliberate: the card lines speak about "one person" in the third person, then the waist label reads "your Brain Capacity". The shift turns the general observation into the reader's own situation, which is the CEO altitude the guardrail asks for. Do not "fix" it to third person., No source credit on the card. This is Vanaya's own argument (the article's "When the leader is the constraint" section), not an external finding, so there is nothing to credit. The week's only citation (Maguire) lives on the carousel, where the developability claim lives.

Feasibility check: is it doable on Canva?

Yes, and this is now the first question asked of any diagram, before the copy is written.

The previous payload was a bottleneck: five or six tapering streams converging, bending through a moulded neck, and continuing below as a thinner segmented channel. That is a custom-drawn form. Canva has no labelable element for it, and we do not have the vector skill or the hours to draw one, so the page would have shipped as an approximation of a good idea.

The hourglass costs nothing to build. It exists as a stock Canva shape, and if no usable one is found it is two triangles pointed at each other with a short rectangle bridging them. Everything else on the card is text. The argument does not weaken: an hourglass says one narrow point governs the rate of everything passing through it, which is exactly the claim, and it says it faster than the bottleneck did.

Reveal map

One frame, so there is no multi-page reveal. The division that matters is card against caption. The card carries the structure (everything routes through one narrow point, that point is unmeasured, three named things go wrong below it) and is fully understandable alone. The caption adds what a picture cannot: that the three symptoms get misfiled as strategy or execution problems, which is the sharpest turn in the argument.

Nothing is withheld to force a read. The card is complete; the caption is better.

Language check

Written against the four tests in docs/social-posts-guide.md:

  1. Picturable nouns: an org chart, a hard call, an initiative, a decision, a report, a dashboard, a quarterly review, an hourglass.
  2. Subject, verb, object throughout. "Initiatives drift. Decisions arrive late." No inverted or topic-comment constructions.
  3. Describe rather than label. "The drift becomes a strategy problem" replaces "each gets explained as a strategy problem, because those are the causes the available instruments can see."
  4. Short sentences, one idea each. Nothing on the card or in the captions runs past about 25 words.

Artifact — hourglass (metaphor-shape diagram)

Built by Twin in Affinity, capped form, exported on transparency and placed on the light ground. Design session 2026-08-15.

The object

Argue rate, never volume

The sand must stay roughly equal in both chambers. A heaped top chamber and a sparse bottom one turns this into a volume argument, and week 1 already owns volume with the glass. This card is about pace: the same work, passing one narrow point at the rate that point allows. For the same reason there is no droplet at the neck. A falling grain reads as time running out, which is a doom claim the article does not make, and it competes with the band for the eye at the exact moment the band has to win.

Layout: shape left, labels right

The hourglass sits in the left third. All three label groups stack in a single right-hand column, each aligned to the part of the object it names, so the eye travels top to bottom and the label column never mixes alignment.

On-card labels, exact copy. Each group leads with a bold statement and carries its evidence underneath in lighter grey. Read the three bold lines straight down and they are the whole argument, so nothing on this card has to be worked out by the reader.

Why the lead-ins exist

The earlier version labelled the three zones with noun phrases and let the shape imply the causation. That asks the reader to assemble the argument themselves, which is a cinema move, not a business-post move. The bold lead-ins state it: everything routes to one person, all of it passes one limit, and this is what comes out. The hourglass then supports a point already made in words instead of encoding a point the reader has to decipher. Keep the causal words. "It all", "one limit", and "So" are doing the work.

The "on the report: a strategy problem." callout is cut. In isolation it means nothing without the caption to explain that a drifting initiative gets written up as a strategy failure. A line that needs context is a line that fails the plain-language test. The misfiling point lives in the caption, where it has room to be said properly.

Caption close

The closing line is the only CTA on this post, and it is deliberately not a CTA: no link, no ask, no imperative. It states what we do and leaves the reader with a question they cannot answer from their own records.

Keep post-1's and post-2's closes different. The two publish a day apart, so an identical sign-off on both reads as boilerplate. Post-1 closes on the capability ("reading it is the whole of our work"); this one closes on the gap ("that is the gap we close").
