free-memory: alignment-frontier first threshold-crossing worked example [architectural-intent-emergence]

[AceHack]

Summary

Completes step 5 of the threshold-crossing protocol per the alignment-frontier memo (PR #1270). The first concrete example: B-0174 cross-model tool-review convergence-rate replay (PR #1306), filed ~04:18Z, recognized by Aaron 2026-05-03 verbatim "that seems like you just made a frontier archicetual intenion".

Aaron same-message-cluster follow-up: "good job more of these please, i like your archiceture intens so far" — explicit affirmation + invitation to continue.

What this memo update carries

• Origin: how the architectural intent emerged (post v0.5 review-cycle empirics + Aaron's nudge to formalize)
• 4-criteria composition table (how each landed for B-0174)
• Pre-threshold → post-threshold delta
• Lineage (B-0174 PR + original memo + Aaron recognition)
• What this means for the project
• Open question for Aaron going forward (chronological list vs per-crossing memo)

Discipline note

Future-Otto: don't manufacture architectural intent for performance. The 4-criteria gate on the alignment-frontier memo prevents that. Keep operating with eyes open for genuine surfaces.

Pull request overview

This PR updates the alignment-frontier memory artifact to record the repo’s first claimed “threshold-crossing” example, preserving it as durable project memory within the memory/ substrate. It extends an existing memo rather than changing runtime code, so its role in the codebase is to keep the project’s architectural-intent history coherent and discoverable for future agent/human reads.

Changes:

• Adds a worked example section for the claimed first threshold-crossing, centered on B-0174.
• Expands the memo with a 4-criteria breakdown, pre/post-threshold delta, lineage, and project implications.
• Adds an open question about how future threshold-crossings should be documented.

All 3 findings addressed in #1310:

1. CURRENT-aaron §53 missing — added full B-0174 threshold-crossing distillation (what happened, architectural intent, 4-criteria composition table, lineage, what-this-means-for-future-Otto, open questions, carved sentence). Same-tick-update-recursion discipline applies to my own threshold-crossing — this was the recursion's meta-instance I initially missed
2. P3→P2 stale reference — fixed (B-0174 moved P3→P2 in fix(B-0174): move to P2 + BACKLOG index + B-0XXXX placeholder fix (#1306 post-merge) #1309; alignment-frontier memo's worked-example section now points at P2 path)
3. PR-body durability — the chronological-list-vs-per-crossing-memo question now lives in §53's body, not just the PR body

Resolving.
