What this branch cost

Stages 2 to 5 of think-2lzo for #806 (stage 1 triage by c-triage-2lzo-1025; stage 4 review by c-review-806-math, think-meci): Evan Daniel’s certificate at evand/square-packing@d99925d retained, walked in report order, replayed with gross and sharp controls, registered as T-243, mapped to V3/C3 after the accepted review, adopted as the house best packing at 182 in the pass of 25 October, and regularized by both strong generators. One moderate-tier records lane (c-import-806-1025) worked it from about 05:41Z to 08:15Z on 25 October, then answered review A from about 08:20Z to 08:50Z, on a shared four-core host (load 2 to 6), at nice with at most two workers, with one merge of main (#808). Science: about 1.2 CPU-minutes for the replay, sharp controls and identity, and 10 to 17 CPU-minutes for the regularization runs and selection; the review lane’s own programs took 129 CPU-seconds. Validation: seven records-tier runs of 2 to 3 minutes, two edit-tier runs, about 20 minutes of pytest, and three paper measurements of 30 seconds each.

New Results and Their Significance

Result	Counts	Rungs	Significance	How confirmed
T-243, Daniel’s new arrangement at 182	182	V3/C3; the house best packing at 182 since this pass	S3, confirmed by the 25 October review	Confirmed, independently re-implemented: the review’s clean-room checker, by a Claude agent, a system family the producer also used; the maintained replay shares the evand-cert reader with the producer

T-243. s(182) ≤ 13970916436214678735385725854133/10^30 = 13.970916436214678735385725854133, printed by the issue as 13.970916436215: 3.17e-3 below T-174 (the house until this pass) and below every report at 182. Measured, no symmetry pairs it one to one with T-174’s packing; the best assignment moves 44 of 182 squares beyond 0.1, and no tilt angle is shared. Credit (M-1 of the review): Evan Daniel, from an L-cut of Francisco Couzo’s 211 packing (T-188), an arrangement of Daniil Ostashev’s design (T-175). Why S3: a new arrangement at the margin of T-158 (2.95e-3 to 3.44e-3), T-164 (1.75e-3) and T-240 (4.45e-3 and 2.78e-3), all S3; no lower bound or optimum.

Results and Dispositions

Work or result	What was established	Evidence	Why it stopped	Disposition and follow-up
Custody	The eight files of the `s182-1024` set (167,915 B) retained at `d99925d` with `LICENSE` and `CREDITS.md` under the source’s MIT licence; both digests the issue prints match; the two checkers pinned against the n183 packet’s identical copies, never run. The declaration paraphrases the commit title’s equality (M-2), so the packet was acquired again: every retained byte unchanged	`acquire_source --check`; `acquisition/sources.json`	Complete	retire-success
Report order	The ledger of 25 October for #806, starts frozen at `main` `bb756e193`: recorded, a new packing, 3.17e-3 below T-174	`ledger.json`; `intake_ledger check`, `render --check`	Complete	retire-success
Replay	Both maintained exact routes accept the certificate and refuse its gross controls (3 jobs, 98,826 pair decisions, 11.53 route CPU s). Walls clear by exactly 5e-21 and pairs by at least 9.99e-21, below binary64 spacing, so the sharp controls ran: all 11 as expected on both routes	`receipts/exact-certification.json.xz`, `receipts/sharp-controls.json`	Complete	retire-success
Stage 4 review	Accepted, copied byte for byte: a clean-room checker by separating axes and exact clipped areas, fourteen controls sharp at 1e-30, the L-cut measured square for square against T-188, T-175, T-181 and T-182; no blocking or major finding, M-1 and M-2 minor, N-1 to N-8 notes	`V-evand-n182-review-check`, `E-evand-n182-review-exact-feasibility`	Complete	retire-success
Mapping	T-243 at V3/C3 with `E-evand-n182-exact-feasibility` (shared-components) and the review’s entry (independent-implementation); claim, notes and next step rewritten; M-1 (credit), M-2 (no “=”), N-2 and N-3 (local minimality is the source’s numerical report, in the notes), N-4 (the lineage measurement) and N-7 (no “first known”) applied; the key credits Daniel after Couzo, Ostashev, Levy	`packing/frontier/results.yaml`, `evidence.yaml`, `verifiers.yaml`, `bibliography.yaml`	Complete	retire-success
Adoption at 182	The house rule adopts T-243 at 182 in the pass of 25 October (182 had not moved that day); T-174 keeps its other houses; the case record, coverage override, prior-state archive, landing (25 October) and custody receipt follow	`select_houses --check`, `adopt_houses --check`, `upper_bound_houses check` and `custody`	Complete	retire-success
Regularization	Grid-slack at 0.5, 1 and 5 degrees and Evan Daniel’s regularizer each drew a same-side view admitted at row 10; the selection draws the regularizer’s (fewer angle classes and hues, more full shared sides, no goal lost), which is the source’s own `s182-1024_regularized.cert` to 1.9e-19. `SETTLED[182]`, decided on T-174’s witness, removed	`packing/cases/regularized_drawings/think-2lzo-2026-10-25/`; `default_drawings --check-state`	Complete	retire-success
N-8	The case’s rigidity statement derived again on the new witness: square 5 translates 0.033032, and 49 of 182 squares move (the source’s 43 flat-motion squares and 6 free squares)	`translation-escape-screen.json`; `assess_frontier_rigidity --check`	Complete	retire-success
Author questions	The review’s four questions and the triage’s question on Subramanya N’s packing are informational by the question rule: the issue’s own start side (14.993549626299, T-188’s) and the review’s measurement settle the start, and no other answer could falsify what the record asserts. Nothing goes under `awaiting_author`	think-2lzo notes	Drafted	continue: the coordinator posts the import reply drafted in think-2lzo after the merge and a verified deploy
Review A	Approve with nits. A1: T-243’s headline reads “3.17e-3 below T-174”. A2: the notes name both thresholds, 49 squares moved beyond 1e-9 and 37 beyond 1e-3 (the regularization item’s `moved`), as do the atlas and run READMEs. A3: this body’s `DATA_REVISION` is the head’s, `b909d2b5`. A4: the optional S3 News story is drafted below. A5: the bibliography note rewrapped	`b909d2b5a`, `0f1f59fc7`, `90dabab55`, dispositions	Complete	retire-success
Requests and watch	#806’s entry mapped to T-243 and its three evidence entries, triage done, beads think-2lzo and think-meci; the evand watch read through `d99925d` with no bead	`packing/campaign/result-requests.yaml`, `intake-watch.yaml`; `check_requests`	Reply due after the merge	continue: coordinator

Changes by Purpose

Area	Result	Principal files or interfaces
Retention and replay	The #806 packet: 10 retained files, custody and import declarations, the frozen comparison, the replay receipt, sharp controls, the identity receipt, README with a Stage 4 Review section	`packing/resources/web/evand-n182-2026-10-25/`
Review	The review document and its programs, outputs and drafted record changes, byte for byte	`docs/project/reviews/review-2026-10-25-evand-n182.md`, `packing/resources/web/evand-n182-2026-10-25/review/review-2026-10-25/`
Report order	The ledger of 25 October for #806, its README mapped and exempt from Flowmark	`packing/campaign/issue-intake/upper-bounds-issue806-20261025/`, `.flowmarkignore`, `docs/project/document-map.yaml`
Records	T-243; three evidence entries; the review’s verifier; the coverage source; the bibliography key and its census spans; T-174’s notes; the requests entry and watch read	`packing/frontier/results.yaml`, `evidence.yaml`, `verifiers.yaml`, `source-coverage.yaml`, `packing/resources/bibliography.yaml`, `packing/contributors/occurrences.yaml`, `packing/campaign/`
Houses	T-243’s packet source, `ADOPTED[182]`, the pass of 25 October; T-243’s prose and the credit at 182; `SETTLED[182]` removed; the case record, witness, coverage override and archive	`packing/devtools/upper_bound_houses.py`, `adopt_houses.py`, `default_drawings.py`, `packing/frontier/n-182.md`, `packing/witnesses/known-best/n-182.yaml`
Drawings	The axis view, the strong runs and their selection, the regularized layer, default drawings and flips, the atlas README	`packing/atlas/known-best/`, `packing/cases/regularized_drawings/think-2lzo-2026-10-25/`
What the house feeds	Custody receipt, translation-escape screen and its tripwires, bound citation, X049 censuses, research tables and STATUS, CERTIFICATE-REACH, composite figure, the sweeps job’s sparse slice	`packing/devtools/house-custody-2026-10-11.json`, `packing/src/sqpack/cli/validate.py`, `.github/workflows/packing-validation.yml` and the generated files
Tests	The packet joins the importer’s roster; a module for its digests, side, margins, sharp controls and identity; the house and atlas tests for the move at 182	`packing/tests/test_upper_bound_reports.py`, `test_upper_bound_reports_806.py`, `test_house_adoption.py`, `test_known_best_atlas.py`
Views and release	INVENTORY, RESULTS, VERIFIERS, the synopsis and URL registry; the explainer’s v0.4.28 for the 243rd result and the house at 182; the other three papers’ measured no-change record; landing stamped; `DATA_REVISION` re-pinned to `b909d2b5`	`packing/frontier/*.md`, `SYNOPSIS.md`, `packing/site-urls.yaml`, `packing/frontier/landings.yaml`, `packing/src/sqpack/release.py`

Drawing before and after (default_drawings --compare against main’s record): 182 was drawn by the house drawing of T-174’s witness, decided no better, with 12 uneven and no near-axis squares and 443 full shared sides; it is now drawn by Evan Daniel’s regularizer’s view of T-243’s witness, regularized, with 4 uneven and no near-axis squares and 429 full shared sides. No strong view gives way to a worse drawing; nothing is pending.

Validation

Replay (local, nice, two workers): upper_bound_reports evand-n182-2026-10-25 certify --workers 2, 3 jobs, 98,826 pair decisions, 11.53 route CPU s; check --replay: 1 certificate and 3 jobs admitted; sharp-controls: all as expected, 45 s; measure_identity: 2.4 s. The review’s checker’s digest is the one its receipt records (242a77a9…8f2d).
House and drawing gates: select_houses --check, adopt_houses --check (70), upper_bound_houses check (70) and custody (70 houses, 206 inputs, 48 mutations refused and restored), default_drawings --check-state --base-ref origin/main (0 pending), apply_closed_form --check, assess_frontier_rigidity --check.
Records: check_results (243 results: 30 recorded, 15 reviewed, 197 confirmed, 1 incomplete), check_requests, intake_ledger check and render --check, check_source_coverage, acquire_source --check, check-claims, check_release_impact (every candidate disposed) and release_pin --check; check_added_blobs --base origin/main: PASS, 823,371 bytes as a thin pack.
Papers: at link revisions f8cca02c, a8184fe4 and, after review A, b909d2b5, render_n11_optimality_review, render_n11_threshold_bound_review and render_packing_methods wrote 51 files byte-identical twice from this tree and once with main’s candidate inputs swapped in (four, then seven, then seven).
Local on c3c33af7c, after the merge of main 886dddce6 (feat(think-clgp): W8, a maintained two-strip checker, with #799's packet and requests entry #808): packing-validate --records --jobs 2 --inner-jobs 1 exit 0 (53 steps) and --edit exit 0 (69 steps); pytest over the importer, s(182) ≤ 13.970916436215: registration request #806, house, atlas, drawing, status, stamp, contributor, citation, ledger, requests, register, coverage, release, identity and sharp-control modules: 1,320 passed, 1 skipped. stamp_landed --apply dated the house at 182 to 2026-10-25 in landings.yaml; release_pin --update re-pinned last.
Hosted on c3c33af7c: three jobs failed, each repaired in 6f6896bbd and 456b090ec: sweeps and suite A found composite-figure.json stale (build_known_best_atlas had refreshed only part of it; build_composite_figure_data --update), and the pdf job drew the explainer at 25 pages against its pinned 24, since the v0.4.28 history line had grown a clause; the line is back to one sentence, which the first head drew at 24. Locally on 3766dbe58: build_composite_figure_data --check and test_rigidity_status pass, and packing-validate --records exits 0 (53 steps).
Hosted: the first head (76eb2dd52, T-243 at V0/C0) passed every required check (packing-required, pages-required and 31 jobs); its deferred checkpoint was cancelled, not failed. 3766dbe58: every job passed but suite C, which one test held 45.61 s against the pull-request surface’s 45 s ceiling (test_each_ceiling_is_the_certified_side_rounded_up_at_the_printed_precision, 15.6 s locally); a473471df reads the coverage register once instead of once a count, 0.27 s locally, and the module’s 51 tests pass. This head (a473471df): Packing validation run 40174785773 and Certificate page run 40174785646 succeeded; packing-required and pages-required pass, 31 checks pass and none fail; the deferred checkpoint skipped.

Hosted on 90dabab55: Packing validation run 40177028092, Certificate page run 40177028091 and Branch mergeability run 40177024687 succeeded; packing-required and pages-required pass, 31 checks pass and none fail; the deferred checkpoint skipped.

Documentation and Replanning

Documentation review: the packet README (custody, the author’s claims and AI-assistance statement, report order, the record, pose by pose, replay and sharp controls, credit, the stage 4 review), the review document, the regularization runs README, the atlas README’s pass section, the ledger’s generated README, T-243’s claim, notes and next step, T-174’s notes.
Selected next entry: after the merge and a verified deploy, the coordinator posts s(182) ≤ 13.970916436215: registration request #806’s import reply from the draft in think-2lzo’s notes and records it under replies.
PR has exactly one S1–S5 label, an editorial rationale and its News/changelog disposition.

Significance: S3 (labelled S3, confirmed by the review): a new arrangement at 182, 3.17e-3 below T-174 (the house until this pass), as T-158, T-164 and T-240 are; no lower bound or optimum. News: not owed, since no result reaches S4; an optional S3 story is drafted below for the coordinator.

News (S3, optional; drafted, for the coordinator to land after the merge or omit):

Daniel’s New Arrangement Becomes the House Best Packing at 182 (25 October 2026). Evan Daniel’s packing at 182, cut from Francisco Couzo’s 211 packing, an arrangement of Daniil Ostashev’s design, and polished, passes a clean-room review here; at 13.970916436215, 3.17e-3 below the packing it replaces and a new arrangement relative to the record, it becomes the house best packing at 182. Details: confirmed, independently re-implemented, by a Claude agent (V3/C3); upper bounds only, no optimality; local minimality is the source’s numerical report. Links: T-243, case 182; review: docs/project/reviews/review-2026-10-25-evand-n182.md.

Announcement

For the owner to post after the merge (rendered with python -m devtools.render_announcement --ids T-243 --github; no profile carries an X handle, so the name is printed):

25 October 2026: 1 new result
s(182) ≤ 13.97092, new best known (verified): Evan Daniel https://squaremath.org/results.html#t-243

Limits

T-243 rests on one AI review; V4 and C4 need a second accepted adversarial review by a distinct reviewer and a human oversight record. The maintained routes share the evand-cert reader with the producer; the independent re-implementation is the review’s checker.
No KKT, local-minimum or optimality statement is made: the source’s are its numerical report. The lineage rests on the review’s geometry; the search history is the source’s account.
The explainer was not rendered here (no headless browser on this host); its v0.4.28 cut owns all its candidate inputs. The other three papers were measured byte-identical.
The drawn view is a pure regularization at the house’s side and proves no other bound.

…V0/C0 The evand-n182-2026-10-25 packet retains the eight files of the s182-1024 set at evand/square-packing d99925d (167,915 bytes) with the licence and credits, pins the two checkers against the n183 packet's copies, freezes the comparison at main bb756e1, replays the certificate on both maintained exact routes with the gross and sharp controls, and measures it pose by pose against T-174, the house witness, T-098, the source's input and its regularized view. The ledger of 25 October for #806 records it, 3.17e-3 below T-174, a new packing. T-243 registers it as reported (S3 draft), with its report evidence, coverage source, bibliography key and reviewed contributor spans; #806's requests entry is mapped (triage done) and the evand watch is read through d99925d with no bead, since the packet pins it.

… M-2, N-2 to N-4, N-7 The stage 4 review of #806 (c-review-806-math, think-meci) accepted the certificate for finite feasibility, no blocking or major finding, two minor and eight notes, and its record-changes.md drafts are applied: - verifiers.yaml: V-evand-n182-review-check (decides), first-party, clean-room, system-family overlap with the producer; the other five programs decide nothing and stay unregistered. - evidence.yaml: the maintained replay E-evand-n182-exact-feasibility, shared-components (the evand-cert reader transcribes Daniel's checkers, as for T-242), and the review's checker as E-evand-n182-review-exact-feasibility, independent-implementation, coverage full; external_review on the report atom and both replays. - results.yaml: T-243 at V3/C3, confirmed, independently re-implemented, by a Claude agent, a system family the producer also used; claim, notes and next_rung rewritten together, the review in reviews, artifacts and controls, S3 confirmed with its rationale; activity and unfinished_confirmations removed. M-1: credit Daniel from an L-cut of Couzo's 211 packing (T-188), an arrangement of Ostashev's design (T-175). M-2: no equality anywhere in the record. N-2 and N-3: local minimality is the source's numerical report, in the notes. N-4: the lineage measurement. N-7: no "first known". - The bibliography credits Daniel after Couzo, Ostashev, Levy, with its census spans; the declaration, packet README (a Stage 4 Review section), coverage entry, ledger lineage, requests entry and resources row follow. The declaration's git_scope paraphrases the commit title (M-2), so the packet was acquired again at the same pin: every retained byte unchanged. - Views rendered; the unpublished T-243 URL row written afresh against main.

…t (think-2lzo) The house rule's adoption of Evan Daniel's s182-1024.cert at evand/square-packing@d99925d (issue 806), V3/C3 with an accepted review since the mapping commit, at the smallest validated side select_houses derives at 182: 3.17e-03 below T-174, a new arrangement found from an L-cut of Francisco Couzo's 211 packing (T-188), an arrangement of Daniil Ostashev's design (T-175). - The pass is 25 October 2026: 182 had not moved that day, so it joins the pass of #794 and #803, and adopt_houses added its row to house-adoption-prior-state-2026-10-25 beside the three there. - upper_bound_houses: T-243's packet source, ADOPTED[182], LATER_PASSES['2026-10-25'] = {182, 268, 303, 304}. - adopt_houses: T-243's prose (the routes share the evand-cert reader; the review's clean-room checker; the measured L-cut lineage) and the credit at 182: Evan Daniel's packing from an L-cut of Couzo's n = 211 packing, an arrangement of Ostashev's design (M-1). apply_closed_form leads with its own paragraph again. - Witness, rendering and the axis view (build_known_best_atlas --update --n 182; regularize_axis_components --update-atlas --n 182). - Strong runs (cases/regularized_drawings/think-2lzo-2026-10-25/): grid-slack at 0.5, 1 and 5 degrees and Evan Daniel's regularizer each draw a view at the witness's side, admitted at row 10; the selection draws the regularizer's (fewer angle classes and hues, more full shared sides than the axis tool's view, no goal lost), which is the source's own s182-1024_regularized.cert to 1.9e-19. layer, then render_regularized_atlas, default_drawings, flip_regularization, regularized_drawings and render_results; SETTLED[182], decided on T-174's witness, removed. 10 to 17 CPU-minutes. - N-8: the rigidity block at 182 derived again on the new witness (screen_translation_escape --update --n 182, assess_frontier_rigidity --update): square 5 translates 0.033032; 49 of 182 squares move. - T-174's notes record the move; T-243's notes and next_rung record the adoption and the regularization. - select_houses --check, adopt_houses --check (70), upper_bound_houses check (70), default_drawings --check-state --base-ref origin/main (0 pending) and apply_closed_form --check pass.

Review A (senior engineering review, round 1) · head a473471 · base main at 886dddc
Reviewer: strong tier, requested claude-opus-5-5 at xhigh · Channel: PR comment
Coverage: 109 of 109 changed files in scope. Read in full or by diff: the five devtools modules, the workflow, the five test modules, the nine record YAMLs, n-182.md, landings.yaml, the custody receipt, the 25 October prior-state archive (decompressed), the 182 rows of every generated JSON, the regularization README and selection, the packet README, and the review's lineage, credit, findings, questions and rungs sections. Checked by digest, gate or test rather than read line by line: the retained source files and review programs, the review's out/, the ledger, the censuses, the SVGs, the witness, the compressed reports and the generated Markdown views (182 rows only). record-changes.md was not read.
Tests run, in a detached worktree at a473471, from packing/, nice, Python 3.14.7 through uv run --frozen: pytest -n 2 on test_evand_exact_certificates, test_house_adoption, test_known_best_atlas, test_upper_bound_reports and test_upper_bound_reports_806: 597 passed (210 s). select_houses --check (pass; 182 not listed as moving), upper_bound_houses check --n 182 (OK, 1 house rebuilds), adopt_houses --check (OK, 70), regularized_drawings --check (agree), check_results (243 results: 30 recorded, 15 reviewed, 197 confirmed, 1 incomplete; exit 0), check_requests (#806 1/1 settled, reply due, closeable). The retained exact_check.py check ran on the packet's s182-1024.cert and s182-1024_regularized.cert and reproduced its receipt. Two scratch measurements are described below.

Summary and Verdict

Verdict: approve with nits. No Blocker, High or Medium finding. Three Low findings and two suggestions, none of which stands in the way of merging before 2026-10-26T00:00Z.

The import, the V3/C3 mapping and the adoption at 182 are correct, and the adoption matches #803's shape item by item. Each point in the brief was checked independently, not taken from the PR body:

Retention. programs/exact_check.py hashes to 242a77a9…8f2d, the program_sha256 in all three of its receipts. identity_lineage.py, kkt_consistency.py and sides.py also match their receipts' digests. Run on the packet's own bytes, the retained checker reproduces out/check-s182-1024.txt line for line (apart from path and CPU time), and the regularized view is valid by both methods. The retained source files match the issue's two printed digests and the custody listing (out/custody.txt). The review document differs from the review lane's pre-Flowmark snapshot (rev806-math/review-before-flowmark.md, after Flowmark) in one sentence, at line 215 ("as they should: the case record's witness W-known-best-n182 is that certificate"). That Edit appears in the review agent's own transcript, so the retained text is the reviewer's final wording, not an import-lane change.
Rung. check_results passes. C3 comes from the exact replay. The "independently re-implemented" qualifier rests on E-evand-n182-review-exact-feasibility (independent-implementation, clean room, V-evand-n182-review-check). E-evand-n182-exact-feasibility is correctly shared-components, because of the evand-cert reader.
Credit. "Evan Daniel, from an L-cut of Francisco Couzo's 211 packing (T-188), an arrangement of Daniil Ostashev's design (T-175)" matches M-1 and the source. The issue (read from the triage's copy, as data) gives the start side 14.993549626299 and lists Couzo's repository among the store's sources. In the register, T-188 is the only 211 packing at that side: T-175 is 14.99369…, T-182 14.99355891…, and T-188 is the house at 211 (ADOPTED[211]). The commit at d99925d names no start, and CREDITS.md at d99925d covers only the lower-bound work (N-6). The key's Daniel after Couzo, Ostashev, Levy, builds-on-project, matches the 154 and 303 precedents. CREDITS[182] = Credit((DANIEL,), (), …) matches the new-arrangement precedent at 183 (T-220).
Adoption at 182. It matches records(think-hx0e, think-o4m0): T-241 and T-242 at V3/C3, M-1's credit at 304 and #795's rows, T-242 adopted at 304 #803's shape item by item: the packet source, ADOPTED[182], the pass-date prose, the T-243 prose and credit, the case record (bounds, evidence, provenance, the prior house as a claim, the regularization block, the adoption paragraph, the verification table and the certificate section), the coverage override and superseded rows, the custody receipt (PingYou's n-182 inputs leave and the s(182) ≤ 13.970916436215: registration request #806 packet's join), landings.yaml (25 October), sources.json, the bound citation, the screen and its tripwires (+5 separating and +34 movable, exactly 1→6 and 15→49 at 182), the censuses, CERTIFICATE-REACH, STATUS, the composite figure and the sweeps sparse slice. Every derived JSON changes only at 182. The decompressed archive's new 182 row is base n-182.md byte for byte, and the 268, 303 and 304 rows are unchanged. Every adoption date is 25 October; the only earlier dates in added lines are the Kaggle listings and earlier reviews.
Pass mechanism. Adding 182 to LATER_PASSES['2026-10-25'] is the documented route (packing/devtools/upper_bound_houses.py:800-806 and :881). 182 had not moved that day, and one archive takes a row per count, as 304 joined in records(think-hx0e, think-o4m0): T-241 and T-242 at V3/C3, M-1's credit at 304 and #795's rows, T-242 adopted at 304 #803. records(think-hx0e, think-o4m0): T-241 and T-242 at V3/C3, M-1's credit at 304 and #795's rows, T-242 adopted at 304 #803's select_houses/PENDING_ADOPTION change was specific to T-242 at 268 and has no counterpart here.
Drawing. The regularizer's same-side view is admitted at row 10 and is non-dominated. Against the axis tool's view of the same witness it wins on classes, hues and both shared-side totals and loses no goal. SETTLED[182] described the axis view of T-174's witness and has to go now that a view is drawn. records(think-hx0e, think-o4m0): T-241 and T-242 at V3/C3, M-1's credit at 304 and #795's rows, T-242 adopted at 304 #803 re-decided SETTLED[304] only because 304 stayed decided-not-drawn, so the two cases are consistent.
Rigidity (N-8). The new scope (square 5, 0.033032 along (1, 0), 49 of 182) is the screen's 182 row. I also checked the PR body's claim that the 49 are the source's 43 flat-motion squares plus 6 free squares. From s182-1024.json's flat_squares and free_squares (0-based), the union equals the screen's movable set exactly, and the six free squares are exactly the six strict-separating ones.
Question rule. Q1 is informational under result-import.md's rule (lines 1463–1471): "one a measurement here could settle is measured instead". The derivation (T-188 rather than T-175, T-181 or T-182) is settled by measurement (square 141 at 0.015 against 0.442) and by the side, which only T-188 has. T-188's own credit (Couzo's arrangement of Ostashev's design) is a register fact the author's answer cannot falsify. Q2 to Q4 change nothing the record asserts. Nothing belongs under awaiting_author.
Explainer cut. Main's newest explainer entry is v0.4.27, so v0.4.28 is the next cut. EXPECTED_PAGE_COUNT stays at 24, and the hosted pdf job passes at this head after 456b090 shortened the history line. The impact decision keeps the adoption clause.
Test changes. In test_each_ceiling_is_the_certified_side_rounded_up_at_the_printed_precision, later depends only on COVERAGE and COVERAGE_ID, never on n, so hoisting it out of the loop keeps the test's meaning exactly. The count changes in test_house_adoption (39→38, 32→31, plus 182 in the later and before maps) and test_known_best_atlas (28→29 sources) each follow from moving 182 off T-174 and onto a new packet.

Findings

A1 (Low): T-243's headline says "below the house", but after this PR T-243 is the house. packing/frontier/results.yaml:34282: "Daniel's new arrangement at 182, 3.17e-3 below the house". The headline renders on result/t-243.html and in tables from today, when the house at 182 is T-243 itself. T-240 ("below T-174 and T-239") and T-241 ("2.53e-3 below T-186") name the result they beat. Fix: "Daniel's new arrangement at 182, 3.17e-3 below T-174".

A2 (Low): T-243's notes count the drawn view's moves at a threshold they do not name, beside a generated block that counts differently. packing/frontier/results.yaml:34418 ("it moves 49 squares, 5 beyond a tenth") and :34444 ("which moves 49 squares, the largest by 0.381") count beyond 1e-9. The generated regularized_drawings item for 182 in the same file says moved: 37 (:35036), which is moved_beyond["1e-3"] (devtools/regularize_evand.py:1709). Both are right; the review's identity table gives "37 (49 beyond 1e-9)". A reader of T-243 sees 49 and 37 for the same view with no explanation. Fix: in T-243's notes write "49 squares beyond 1e-9 (37 beyond 1e-3)" at least once. The same applies, optionally, to packing/atlas/known-best/README.md:865 and packing/cases/regularized_drawings/think-2lzo-2026-10-25/README.md:52.

A3 (Low): the PR body names a superseded DATA_REVISION. Under "Changes by Purpose", the "Views and release" row says "DATA_REVISION re-pinned to 470b640e". The head pins 6f6896bbd789… (packing/src/sqpack/release.py:802, commit 3766dbe). Fix: edit the PR body to 6f6896bb, the value think-2lzo's notes already give.

Suggestions

A4 (suggestion): consider drafting the optional S3 News story. The PR records "S3 stays out of News". That is allowed, since News is optional at S3 (packing/campaign/result-import.md:1245-1247), but the rule's named omission case is "an intermediate research checkpoint without a distinct reader-facing development", and a new house best packing is reader-facing. The S3 house adoptions T-220, T-224, T-230 and T-240 each have a site-changelog.yaml entry, and #803 drafted an optional S3 story for the coordinator. Fix (pick one): draft a short entry for the coordinator to land after the merge, as #803 did; or keep the omission and give a reason beyond "S3".

A5 (suggestion): one overlong line in the new bibliography note. packing/resources/bibliography.yaml:4172 ("the Levy link, as the 22 October key of Daniel's 303 does. The binary64 packing it was solved from, its") is 109 columns inside a folded scalar, unlike the 90-column wrapping around it. It is cosmetic only, because YAML folds it. Fix: rewrap.

False Positives / Do Not Fix

The review document's one-sentence difference from the lane's pre-Flowmark snapshot is the reviewer's own last edit (see Retention). Leave it.
regularized/index.json, 182 reference.exact_frame.retained_certificate names franciscouzo-2026/n-182-rational.yaml.gz with matches_retained_certificate: false. That is the axis tool's count-keyed lookup, shared by 46 entries, and not a claim about T-243.
known-best-packings/sources.json's retention policy says "no upstream program or prose is copied" while the packet keeps CREDITS.md. It is the generator's template, shared by 22 entries with the same packet layout (devtools/upper_bound_houses.py:105). Not this PR's to change.
selection-adopt-2026-10-25-n182.md's /tmp/... command path. 19 of the 26 selection records do the same.
T-174's next_rung still describes its 17 October house count. records(#763): T-240 reviewed at V3/C3, adopted at 268 and 303 and regularized #794 left it unchanged when 268 moved off T-174, and T-174’s notes record the move at 182.
run_review.sh reads witnesses/known-best/n-182.yaml, which this PR changes, so re-running it at the new main would compare s(182) ≤ 13.970916436215: registration request #806 with itself. The evidence entry pins REPO to bb756e193, and the program is retained byte for byte. Do not edit it.
The superseded_reports reasons for Casson's and Couzo's 2026 rows at 182 still mention T-098. That is pre-existing wording; only superseded_by is this PR's.

Merge Notes (not findings)

The pass is dated 25 October (LATER_PASSES['2026-10-25'], house-adoption-prior-state-2026-10-25.json.xz, landings.yaml), so this PR has to merge before 2026-10-26T00:00Z. If main moves first, follow think-2lzo's re-pin plan (a merge commit, stamp_landed --apply, re-measure the three papers, re-pin).
records(#804): Hyukdong Kim's exact sides at 172 and 263 as T-244; 88, 126 and 199 are T-193's #813 also cuts the explainer at v0.4.28 and re-cuts after this merges. If records(#804): Hyukdong Kim's exact sides at 172 and 263 as T-244; 88, 126 and 199 are T-193's #813 also writes to the 25 October pass or archive, the second to merge resolves the .xz archive by regenerating it, not by text merge.

Dedicated reviews: correctness applies (exact feasibility, persisted register and house records), and this review covers it at the coordinator's request. Security and performance do not apply: the PR adds no execution surface, and its one runtime change makes a test faster.

CI Status

At a473471: Packing validation and Certificate page succeeded. packing-required and pages-required pass, every non-skipped job passes (including pdf, sweeps and suites A to D), and the deferred and post-merge jobs are skipped as designed. No check failed.

Dispositions for review A

Thank you for the review. All five nits are fixed at head 90dabab55.

Item	Disposition	Where
A1: T-243's headline compares to the house, not to T-174	Fixed. The headline now reads "Daniel's new arrangement at 182, 3.17e-3 below T-174".	`b909d2b5a`, `packing/frontier/results.yaml`
A2: the 49 moved squares carry no threshold beside the block's `moved: 37`	Fixed. T-243's notes now say "49 squares beyond 1e-9 (37 beyond 1e-3, the count the regularized_drawings item below gives as moved)". The atlas README's pass section and the run README say the same. The over-800-character paragraph this produced was split before "Both strong generators decided".	`b909d2b5a`, `packing/frontier/results.yaml`, `packing/atlas/known-best/README.md`, `packing/cases/regularized_drawings/think-2lzo-2026-10-25/README.md`
A3: the body's `DATA_REVISION` is stale	Fixed in the body. It now names `b909d2b5`, which is what `release.py` pins at this head.	PR body, Changes by Purpose
A4: the optional S3 News story	Drafted in the body in #803's form, for the coordinator to land after the merge or omit. The Significance line now compares to T-174, as A1 does.	PR body, Documentation and Replanning
A5: bibliography.yaml:4172 is unwrapped	Fixed. The note is rewrapped, and its folded text still equals the packet's `register.bibliography.note`.	`b909d2b5a`, `packing/resources/bibliography.yaml`

These edits changed the papers' inputs, so the no-change record was measured again at link revision b909d2b5 (0f1f59fc7). The three papers wrote 51 files, byte-identical twice from this tree and once with main's seven candidate inputs swapped in. stamp_landed --apply (25 October) changed nothing, and release_pin --update re-pinned last (90dabab55). Main is still at 886dddce6, so no merge was needed.

Validation at 90dabab55:

packing-validate --records --jobs 2 --inner-jobs 1: exit 0 (53 steps).
pytest over the 13 affected modules (s(182) ≤ 13.970916436215: registration request #806, results register, register prose, result status, bound citations, contributors, regularized and default drawings, stamp, release, release impact, release pin, house adoption): 555 passed.

AI Description

• Register Evan Daniel’s certificate as T-243 after exact replay and an accepted independent review.
• Adopt its improved s(182) bound as the house best packing, retaining T-174 as history.
• Regularize the new witness and refresh atlas, case, intake, and release records.

High-Level Assessment

Retaining the upstream certificate, distinguishing the maintained replay from the independently written review checker, and using the existing house-adoption and regularization pipelines fits the repository’s evidence model. Merely updating the displayed bound would lose custody, verification, and drawing provenance.

Code Review by Qodo

1. The 182 bound shows a non-upward value 📎

Description

The reported_upper_bound.value and verified_upper_bound.value fields record
13.9709164362146788 instead of the required 12-place upward display 13.970916436215. The exact
side is below that ceiling, so readers and downstream records receive a value with the wrong
required precision for the registered bound.

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The new 182 upper-bound record displays the exact side with 16 decimal places instead of the required 12-place upward-rounded value `13.970916436215`.

## Fix Focus Areas
- packing/frontier/n-182.md[14-15]
- packing/frontier/results.yaml[34283-34286]
- packing/atlas/known-best/bound-citations.json[185-185]

## Recommended Fix
Set the registered displayed value in each affected bound record and citation to `13.970916436215`, while retaining the exact rational side separately, then update or add focused tests that assert the displayed value is the 12-place upward rounding.

2. Malformed certificates crash with tracebacks 📘

Description

exact_check.py invokes check() or controls() directly from main() without catching parsing,
validation, or file errors. A malformed certificate or missing input reaches ValueError, decoding
errors, or OSError at the CLI boundary and exits through an uncaught traceback instead of a
concise non-zero refusal.

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The exact certificate checker lets parse, validation, decoding, and file errors escape from its CLI entrypoint, producing tracebacks for malformed user-provided inputs.

## Fix Focus Areas
- packing/resources/web/evand-n182-2026-10-25/review/review-2026-10-25/programs/exact_check.py[499-516]

## Recommended Fix
Wrap certificate processing and receipt writing in a targeted exception handler for `OSError`, `UnicodeError`, `IndexError`, `KeyError`, `ValueError`, and related expected validation failures. Print a concise `refused: ...` message to stderr and return a non-zero exit code while preserving unexpected programming errors.

3. Failed reviews leave partial receipts 📘

Description

run_review.sh pipes each long-running checker through tee, which creates the text receipt before
the checker completes and provides no cleanup trap. When a checker fails after emitting only part of
its output, the stale partial receipt remains in out/ and can be mistaken for a completed review
on a retry or by a later reader.

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The review runner writes checker output directly through `tee` into final receipt paths without removing those files when a checker fails.

## Fix Focus Areas
- packing/resources/web/evand-n182-2026-10-25/review/review-2026-10-25/programs/run_review.sh[12-26]

## Recommended Fix
Add an EXIT trap that removes newly created receipt files on non-zero exit, or write each receipt to a temporary file and rename it into place only after the corresponding checker and pipeline complete successfully. Ensure the cleanup covers both the text receipts created by `tee` and JSON receipts created by the Python tools.

4. Review hashes can mismatch parsed inputs 📘

Description

sides.py parses its certificate and comparison files through separate opens, then reopens those
paths in digest() when constructing the receipt; kkt_consistency.py and identity_lineage.py
use the same pattern. If any input changes between parsing and digesting, the receipt hashes bytes
different from the data used for the calculations and no longer proves the reviewed snapshot.

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The review utilities parse input files and later reopen them to calculate receipt hashes, so a file mutation between those reads can make the recorded digest describe different bytes from the parsed data.

## Fix Focus Areas
- packing/resources/web/evand-n182-2026-10-25/review/review-2026-10-25/programs/sides.py[27-35]
- packing/resources/web/evand-n182-2026-10-25/review/review-2026-10-25/programs/sides.py[56-75]
- packing/resources/web/evand-n182-2026-10-25/review/review-2026-10-25/programs/kkt_consistency.py[43-53]
- packing/resources/web/evand-n182-2026-10-25/review/review-2026-10-25/programs/identity_lineage.py[62-92]

## Recommended Fix
Load each input as bytes once, compute its SHA-256 from that byte snapshot, and parse the same snapshot. Pass snapshot records or parsed data with its digest through the calculation pipeline, and add a test that mutates a file between the old parse and hash points to verify the receipt remains tied to the parsed bytes.

#814 registered T-243 at 182 and adopted it, and cut the explainer as v0.4.28. Resolved by keeping both sides: the register orders T-243 before T-244, so the ids are contiguous; the requests record keeps #804's entry before #806's and #799's acknowledgement; evidence, coverage, bibliography and census spans take main's and add this branch's; release.py takes main's and adds this branch's no-change record (re-measured next, with the explainer re-cut as v0.4.29). The generated views (RESULTS, INVENTORY, VERIFIERS, the URL registry and its document) are main's, rendered again; the synopsis counts 244 results. The 25 October pass archive is untouched.

…0.4.28 #814 took v0.4.28 for T-243, so T-244 takes the register from main's 243 entries to 244 at the next patch. cut_release v0.4.29 (patch, October 25, 2026) ran the explainer's 316 edition tests, all passing. This branch's earlier v0.4.28 entries gave way to main's in the merge of 46e3555.

After #806's final comment, #814's News and the explainer PDF's page count, at link revision 1b75d2f, twice from this tree and once with main 46e3555's results.yaml, result-requests.yaml, source-coverage.yaml, site_resources.py and render_n11_lower_bounds_explainer_pdf.py swapped in and the new profile set aside (69 files each): the three papers byte-identical; the explainer differs only in its count.

…results become T-245 and T-246 Main registered T-243, Evan Daniel's certificate at 182 (#806), and open PR #813 holds T-244 for Hyukdong Kim's exact sides at 172 and 263 (#804). No open branch goes past T-244, so this branch's two results take the next free ids: Jatloe's reported Lean proof that s(12) = 4 (#810, think-4l14) is T-245, and Daniel's degree-7213 s(29) minimal polynomial (#545, #811, think-6gti) is T-246. Main's T-243 is kept exactly. Every file this branch changed was merged three ways from its own version with T-244 to T-246 and T-243 to T-245 (and t-243/t-244 to t-245/t-246) applied first, the merge base, which names neither id, and main, so no reference to main's T-243 was rewritten. Conflicts were resolved by keeping both sides' entries whole: #806's request entry before #810's and #811's; main's n182 occurrences, evidence atoms, coverage source and bibliography key before this branch's; main's evand/square-packing watch read before the Jatloe12SquaresFormalized one; main's result/t-243.html row before t-245 and t-246; and in results.yaml, T-243 before T-245 and T-246. In release.py the explainer takes v0.4.29 over main's v0.4.28, main's v0.4.28 entry and decision kept; main's no-change record is kept whole beside this branch's; DATA_REVISION is main's until it is re-pinned. RESULTS, INVENTORY, VERIFIERS, STATUS, the synopsis tables and site-urls.md were re-rendered by their generators; SYNOPSIS counts 245 registered, 213 by others. check_results reports one problem, by design until #813 lands: the ids are not contiguous, T-244 being #813's.

… the merge of main 46e3555 Main (#814) registered T-243 at 182 and took the explainer's v0.4.28, so this branch's results became T-245 and T-246 and the explainer takes v0.4.29. The optimality review, the threshold-bound review and the methods survey, rendered at link revision ab33e3b into empty site directories twice from this tree and once with main's nine candidate inputs swapped in and jatloe.md removed, write all 51 files byte-identical across the three, so they keep v0.1.11, v0.1.4 and v0.2.7.

Main's 25 October pass adopted T-243 at 182 (#814) beside this branch's 26 October pass at 268. Conflicts resolved by keeping both: - upper_bound_houses: ADOPTED[182] = T-243 and ADOPTED[268] = T-242; LATER_PASSES['2026-10-25'] = {182, 268, 303, 304} and ['2026-10-26'] = {268}; the history comments name both. - SCREEN_FINDINGS: n=1..200 from main (182), n=1..324 (124, 1326, 302, 5356), which screen_translation_escape --update --n 268 re-derives. - release.py: main's no-change records, then this branch's H2 record. - test_house_adoption: 38 held counts (182 left the hold on main); 182 -> T-243 and 268 -> T-242 in both house maps. - source-coverage, document map, synopsis row and the atlas README: main's 182 entry, then this branch's 268 entry. - regularized/index.json: both run blocks; totals = main + branch - base (views by generator 27 / 38 / 21). - Regenerated from main's copies: flip_regularization --update, both X049 censuses --update, upper_bound_houses custody (70 houses, 206 inputs, 48 mutations refused and restored).
