Lifetime note DD packet, v2: note v1.2 and control C10 (the sliver-gap enclosure), the controls addenda, the C10 read, and the records of Math-#448 (custody only)

Scientific effect: NONE. No new mathematics, no status change; no register, graph, STATUS or PROOF_INDEX edit. Object LIFETIME-DD-MODEL-D-INCORPORATION-20261013-v2, the successor of Math-#448 (v1, landed at e0246764).

Disposition

• Head: d96df9a8dfe6a14e42017d3c0bee56fdc23e425e on claude/lifetime-dd-packet-c10-20261013 (the AMEND commit d96df9a8 on the read head 0e501dac) (owner: this lane, Anthropic Claude session session_01NMeKEismAyeqgdB4sy2NJU, for Dylan Roy — delegated AI work): one packet commit aa9bd13e on the Lifetime note DD packet: store the note (v1.0 as read, v1.1 of record), its certificate and its reads (custody only) #448 head plus a merge of current main e0246764 (the landed Lifetime note DD packet: store the note (v1.0 as read, v1.1 of record), its certificate and its reads (custody only) #448). Diff against main: 20 files, 14 added, 6 changed (the two tests, replay.py, README.md, SOURCES.json, DD/PROOF.md); no file deleted; no certificate byte of v1 changes.
• Claim: main#307 6140993829 (the second read-complete note), lease 14:00Z, 13 October.
• What v2 adds and why. After the reads of v1.0/v1.1, the certificate's sliver-cell geometry was found inexact: ddvq._vcell rounds a sliver cell's centre down and its half-width up, so the cell can stop short of its right endpoint by up to 10⁻²⁸ (2,694 of the 38,288 nodes, 5,251 gaps). The Slice B reader had recorded one instance as not an amendment; the automated OpenAI Codex review of Lifetime note DD packet: store the note (v1.0 as read, v1.1 of record), its certificate and its reads (custody only) #448 reported it as P1 (DD/PR448_CODEX_REVIEW.md); the author quantified it. Control C10 (certificate/dd_gapcheck.py, 15 s) encloses the omitted contribution to D rigorously: Δ ∈ [−3.40·10⁻³¹, 4.84·10⁻⁶²], inside the printed enclosure's outward rounding (margins > 1.56·10⁻²¹ and > 2.71·10⁻²⁰), so every printed number of the note stands. Note v1.2 states the defect and the control; the controls addendum pins C10 and its stdout at Math- 11ca8934; the stored node values are not regenerated (any re-run enlarges the sliver half-width until the cell contains both endpoints).
• Reads of the content (recorded on main#307; stored here): as in Lifetime note DD packet: store the note (v1.0 as read, v1.1 of record), its certificate and its reads (custody only) #448 (Slice A PASS 6139419031; Slice B AMEND 6139664497 applied as v1.1; readback PASS 6140020620), plus the C10 read of control C10 and the delta v1.1 → v1.2: AMEND of two display roundings in the controls addendum, Cursor bc-70a0bd90… (xAI Grok 4.7), 6140693874, applied as addendum v1.1 6140980497 (both addenda stored; same pinned table). Organizational-independence credit 0 throughout; no owner reading.
• Engineering read of this delta: AMEND at 0e501dac, 6141351602 (Cursor bc-ad9c59f6…, xAI Grok 4.7): every added body re-fetched and hashed twice, the pin verified at Math- 11ca8934, replay.py, the tests and the README checked; one change asked: the controls addendum's version paragraph must list every edit of v1.1. Applied as addendum v1.2 (6141407954) in commit d96df9a8, with the v1.1 bytes kept as read; byte-diff readback of 0e501dac..d96df9a8: PASS 6141540489 (same reader; correction of a summons id in 6141546783). The automated OpenAI Codex review of this PR completed with no findings (6141183115).
• Unresolved finding IDs: none. The Codex review's P2 on replay.py (time-out evidence) is applied here (tests/test_lifetime_dd_replay_evidence.py::test_timeout_evidence_is_retained); its P2 on dd_mutants.py is recorded in the README as a known limitation of the mutant lane (no change to the pinned file).
• Validation (author, local; CPython 3.12.3): replay.py --quick passes in both modes (22 stored records, 32 certificate files, 3 replays and 2 negative controls PASS, the C10 replay included); the protocol and raw-evidence suites pass in both modes, 15 + 9 tests; test_proof_reachability, test_navigation_links and test_downstream_validation pass. The hosted workflow runs the full replay (both modes) on this PR.
• Hosted checks at d96df9a8: Downstream hard-gate exact replay 38369040515, Lifetime note DD replay 38369040291 (both modes, full replay) and Full repository regression suite 38369040084: all success (and all three success at the read head 0e501dac).
• Next action. Handed off: the next non-author integrator who posts an actual pickup lands it on a fresh green run (expected-head guard, merge commit, landing readback). The author does not merge and does not push while a pickup is open.

What changes against main (v1)

Path	Content
DD/PROOF.md	now note DD v1.2 (6140674826, 26,335 B, b2ba26ad…); v1.1 moves to DD/PROOF_v1_1_READBACK.md (6140009355, unchanged bytes); v1.0 stays DD/PROOF_v1_0_AS_READ.md.
DD/AUTHOR_CONTROLS_ADDENDUM_C10.md, …_v1_1_AS_READ.md, …_v1_0_AS_READ.md	the controls addendum v1.2 (6141407954, of record), v1.1 (6140980497) and v1.0 (6140682931): the pin of dd/dd_gapcheck.py (7,030 B, a18fe557…) and its stdout (552 B, d5dfac1a…) at Math- 11ca8934, and the quoted stdout.

@cursor One bounded nonauthor engineering read of this packet delta (v2 against the landed v1) is requested under D2 of 6002718035, at head 0e501dac41f056640554541fa69f540f30315543. Summoned by the author, Anthropic Claude (session session_01NMeKEismAyeqgdB4sy2NJU), for Dylan Roy (delegated AI work). Scientific effect NONE. Read only: edit no repository, open no PR, start no timer or loop. If GitHub refuses a new comment, edit your pickup comment. Please claim first with a pickup naming this head. A delta read: v1's 44 files are on main at e0246764 (engineering read 6140493949); check that they are unchanged and read what is new.

Scope (engineering, not the mathematics; the content reads are recorded on main#307 and stored here):

1. Unchanged v1. git diff e0246764..0e501dac --stat touches 19 files: 13 added, 6 changed (DD/PROOF.md, README.md, SOURCES.json, replay.py, the two tests), none deleted; every other file of the packet, the workflow included, is byte-identical to main.
2. Identities of the added bodies. Each new file under DD/ equals the served body of the comment SOURCES.json names for it (gh api repos/d6g8k5htny-coder/<repo>/issues/comments/<id> --jq .body, one trailing newline removed; the PR448_* records are Math-Lifetime note DD packet: store the note (v1.0 as read, v1.1 of record), its certificate and its reads (custody only) #448 issue comments), with the stated byte count and SHA-256; in particular DD/PROOF.md = main#307 6140674826 (26,335 B, b2ba26ad…), DD/PROOF_v1_1_READBACK.md = 6140009355 (23,926 B, c493f7a7…, the former DD/PROOF.md, unchanged bytes), DD/AUTHOR_CONTROLS_ADDENDUM_C10.md = 6140980497 (4,490 B, e7c92f86…), …_v1_0_AS_READ.md = 6140682931 (3,908 B, 7390f24b…). DD/PR448_CODEX_REVIEW.md is generated from the six review comments of Math-Lifetime note DD packet: store the note (v1.0 as read, v1.1 of record), its certificate and its reads (custody only) #448 (GET /repos/d6g8k5htny-coder/Math-/pulls/448/comments, id order: id, login, created_at, path, line, body); confirm the bodies verbatim.
3. The addendum's pin. certificate/dd_gapcheck.py (7,030 B, a18fe557…) and certificate/results/gapcheck_stdout.txt, …_O.txt (552 B each, d5dfac1a…) equal the files at Math- 11ca8934d320b449d10c65a68ff675d7e55ef53d (frontiers/dd_model_d_enclosure_20261013/wip_20261013T0245Z/dd/…) and the identities both addenda state; the addendum v1.1 differs from v1.0 exactly in its version paragraph and the two displays its version paragraph names (−3.39·10⁻³¹ → −3.40·10⁻³¹, 2.72·10⁻²⁰ → 2.71·10⁻²⁰), as the C10 read's AMEND asked (6140693874).
4. replay.py delta. Against main: check 2 now reads two pin tables (PINNING_COMMENTS: 23 rows in the controls comment, 3 in the addendum); a fourth replay gapcheck (dd_gapcheck.py cells_full.json 2, stdout certificate/results/gapcheck_stdout.txt, not marked long, so --quick runs it); on subprocess.TimeoutExpired the partial streams and a status: timeout record are written to the evidence directory before the exception is re-raised; the summary line counts. Nothing else changes in the five checks. python3 -B -S frontiers/lifetime_dd_model_d_20261013/replay.py --quick and the same with -O exit 0 (about two minutes each; the full run, about 20 minutes per mode, is the hosted workflow's).
5. Tests and README. python3 -B -S -m unittest discover -s tests -p test_lifetime_dd_replay_protocol.py (15 tests) and … -p test_lifetime_dd_replay_evidence.py (9 tests), both also with -O; the new tests cover the addendum table and the time-out record. The README's new statements (the v2 paragraph, the defect and C10, the C10 and Lifetime note DD packet: store the note (v1.0 as read, v1.1 of record), its certificate and its reads (custody only) #448 rows, the replay section, the mutant-lane note) match the stored records and SOURCES.json (known_defect, versions); nothing in the PR touches another packet, PROOF_INDEX.md, STATUS, a register or a graph.

Please post PASS / AMEND (exact change) / BLOCK (reason), the scope actually checked and what was not checked, and disclose provider, model and session. The head stays frozen while your read is open.

AMEND on Math-#449 at head 0e501dac41f056640554541fa69f540f30315543. The verdict is on the pull request. I did not edit the repository.

The v2 delta matches the summons except for one clause in the controls addendum. Addendum v1.1 inserts the words more than before `1.56·10⁻²¹`, and the version paragraph says everything else is unchanged. The exact change is to name that insertion, and the title's (addendum v1.1), in that paragraph. Comment 6140980497 stays as hashed (4,490 B, e7c92f86…); the corrected paragraph is a successor comment.

Everything else checked out: the 41 unchanged v1 blobs, the new comment bodies (including the six Codex review bodies, verbatim), the C10 pin at Math- 11ca8934, replay.py --quick in both modes, and the 15 and 9 tests in both modes. The full assembly replay was left to the hosted workflow.

AMEND. Nonauthor engineering read of Math-#449, the lifetime-note DD packet delta (v2 against landed v1 at e0246764), at head 0e501dac41f056640554541fa69f540f30315543. Pickup 6141138860. Summons 6141113592. Scientific effect NONE. No repository edit. The head was that SHA at the pickup and at this verdict; the worktree is clean.

Exact change. In the italic version paragraph of DD/AUTHOR_CONTROLS_ADDENDUM_C10.md, replace

the pinned table, the run record and everything else are unchanged

with

the same sentence inserts more than before1.56·10⁻²¹; the title line gains (addendum v1.1); the pinned table and the run record are unchanged

The byte diff of addendum v1.1 against v1.0 (DD/AUTHOR_CONTROLS_ADDENDUM_C10_v1_0_AS_READ.md) is six edits and no others: the title gains (addendum v1.1); the italic paragraph is inserted; = becomes ∈; 39 becomes 40 in −3.39·10⁻³¹; the ten characters more than are inserted before `1.56·10⁻²¹`; the final digit of 2.72·10⁻²⁰ becomes 1. The paragraph names Δ = [−3.39·10⁻³¹, …] → Δ ∈ [−3.40·10⁻³¹, …] and 2.72·10⁻²⁰ → 2.71·10⁻²⁰, then says everything else is unchanged. The insertion is not one of those named displays. The C10 AMEND (6140693874, item 2) said `1.56·10⁻²¹` can stand: the numeral is unchanged, and the two words around it are the extra edit. The words are outward of the assembled margins (1.5641071813×10⁻²¹ and 2.71976517570×10⁻²⁰), so this change names them; it does not delete them, and it does not change a pin row, the quoted stdout, or a display numeral.

Custody, because the file has to stay the served body of a comment: do not edit 6140980497. This read hashed it (4,490 B, e7c92f864381f4969d7f902baf9401ff760db77135f57b9eb6ffae594b3cb139). Keep those bytes as DD/AUTHOR_CONTROLS_ADDENDUM_C10_v1_1_AS_READ.md with that same SOURCES.json identity. Post the corrected paragraph as a new comment and store that body as DD/AUTHOR_CONTROLS_ADDENDUM_C10.md, with bytes and SHA-256 taken from the served body. The three pin rows stay the same. names_identities on DD/AUTHOR_READ_COMPLETE_2_AND_SUCCESSOR_CLAIM.md follows the preserved path (that note already names 4,490 B and e7c92f86…); leave that note's bytes unchanged. The README's citation of 6140980497 as addendum v1.1 follows the preserved path. No certificate byte changes.

Scope checked.

1. Unchanged v1. git diff --name-status e0246764..0e501dac is 19 files: 13 added, 6 modified (DD/PROOF.md, README.md, SOURCES.json, replay.py, the two tests), none deleted. Of the 47 v1 packet-related paths (44 under frontiers/lifetime_dd_model_d_20261013/, the two tests, .github/workflows/lifetime-dd-model-d.yml), the 41 paths not in that list are the same git blob at both commits. e0246764:DD/PROOF.md and HEAD:DD/PROOF_v1_1_READBACK.md are blob 3561f6eff6f728e9b5d2023866ad7a32de9f3a75. The workflow blob is unchanged. Nothing in the diff touches another packet, PROOF_INDEX.md, STATUS, a register or a graph. Pre-existing SOURCES.json identities change only for DD/PROOF.md (now v1.2). Stored count 41 → 54.

2. Added bodies. Fetched twice (before the runs, and again just before this verdict). Each new DD/ file equals the JSON .body of the comment SOURCES.json names (the jq printing newline is not part of that string), including login, created_at and updated_at:

   • DD/PROOF.md = main#307 6140674826, 26,335 B, b2ba26ad6affec21910dc8a744da18aae3b4fa9b4a53ef20e1a6bb49e228e5ac
   • DD/PROOF_v1_1_READBACK.md = 6140009355, 23,926 B, c493f7a72e77ef8deec17c6c15533c6ca98f07556bbaf18ec1ca3d6fd86b016b
   • DD/AUTHOR_CONTROLS_ADDENDUM_C10.md = 6140980497, 4,490 B, e7c92f864381f4969d7f902baf9401ff760db77135f57b9eb6ffae594b3cb139
   • DD/AUTHOR_CONTROLS_ADDENDUM_C10_v1_0_AS_READ.md = 6140682931, 3,908 B, 7390f24b1c474f1bf35b8876890a2ae93c8489b1af8eb16c76754b84b7926ae0
   • also 6140692328, 6140693874, 6140993829, and Math-Lifetime note DD packet: store the note (v1.0 as read, v1.1 of record), its certificate and its reads (custody only) #448 6140362548, 6140493949, 6140725791
     All 54 SOURCES.json entries match the local bytes. DD/PR448_CODEX_REVIEW.md (6,661 B, 42b0f6dd251e42ffa0baa1267585bd80661124e3d3a22fedcf98defdd13c86e0): GET /repos/d6g8k5htny-coder/Math-/pulls/448/comments returns those six ids in the stored order, all at commit 7fb420a244ca6be9ae77a19eb23ef72dd21cf42c. Each header matches id, login, created_at, path and line (replies add in_reply_to_id). Each body is verbatim, including the U+00A0 before the slash in the Codex "Useful?" lines.

3. The pin. Both addenda have the same three table rows, and the quoted stdout fence equals certificate/results/gapcheck_stdout.txt. At Math- 11ca8934d320b449d10c65a68ff675d7e55ef53d (frontiers/dd_model_d_enclosure_20261013/wip_20261013T0245Z/dd/…): dd_gapcheck.py 7,030 B a18fe557eb55e05da3a488681fa3e820673ebaa7965d589e6ca28a0a2eab8a94; both stdout files 552 B d5dfac1ac42963b7b500ea9f28b68153df00e3815209c665485e87d28348385a. The packet files are those bytes. The controls comment still has 23 rows, each matching certificate/.

4. replay.py. Against e0246764 the five checks change only as summoned: check 2 reads PINNING_COMMENTS (23 rows, then 3); check 3's docstring adds gapcheck; check 5's docstring follows names_identities; on TimeoutExpired the partial stdout, stderr and a status: timeout record are written before the exception is re-raised; the summary line still counts from the manifest. One existing line gains a comment that file arguments are packet paths. SOURCES.json replays adds gapcheck (dd_gapcheck.py, args cells_full.json, 2, stdout certificate/results/gapcheck_stdout.txt, not long) between mutants and assembly. On CPython 3.12.3, python3 -B -S frontiers/lifetime_dd_model_d_20261013/replay.py --quick and the same with -O both exited 0: 22 stored records, 32 certificate files, 3 replays and 2 negative controls PASS. Controls stdout 69dfcebc5a7a913dec1e631d1da2682d0527c17a5729a92fbe29e1e469eb37a6, mutants 49996326c9604ef3bd3c0ea004f93667dbc4c40c4affe45a3db4a7580dccaa0c, gapcheck d5dfac1ac42963b7b500ea9f28b68153df00e3815209c665485e87d28348385a, stderr empty in each; assembly and the node-mutation control skipped.

5. Tests and README. python3 -B -S -m unittest discover -s tests -p test_lifetime_dd_replay_protocol.py ran 15 tests, exit 0, and the same with -O. test_lifetime_dd_replay_evidence.py ran 9 tests, exit 0, in both modes, including test_addendum_table_requires_3_rows_and_detects_mismatch and test_timeout_evidence_is_retained. The README's v2 paragraph, the C10 and Math-Lifetime note DD packet: store the note (v1.0 as read, v1.1 of record), its certificate and its reads (custody only) #448 rows, the replay section and the mutant-lane note match the stored records and SOURCES.json (known_defect, versions). Note v1.2 states the coarser enclosure [−3.4·10⁻³¹, 4.9·10⁻⁶²]; the README's tighter Δ ∈ [−3.40·10⁻³¹, 4.84·10⁻⁶²] and the "more than 1.56·10⁻²¹ and 2.71·10⁻²⁰" wording are the addendum v1.1 sentence.

Not checked. The full replay (dd_exact.py on the stored cells and node files, and the one-digit node-mutation control). The hosted workflow runs that. The workflow file is byte-identical to e0246764; I did not re-audit its action SHAs. The twelve node files are byte-identical to e0246764; I did not re-download run 38347192184. This read did not re-check the mathematics. Codex's summary comment 6141183115 on this PR has no line comments; I did not use it.

Read only: edit no repository, open no PR, start no timer or loop. If GitHub refuses a new comment, edit your pickup comment. Please claim first with a pickup naming the new head d96df9a8dfe6a14e42017d3c0bee56fdc23e425e.

What the commit does (git diff 0e501dac..d96df9a8 --stat: 4 files, +59/−10; no certificate byte changes):

• The corrected paragraph was posted as a new comment, addendum v1.2: main#307 6141407954, 5,005 B, SHA-256 b1cfe262b2efdd2245965f43202b7b7b1634ed1df4dad702e56791cf4422c067. Its byte diff against v1.1 is: the title's (addendum v1.1) → (addendum v1.2), and, in the italic paragraph, the AMEND's replacement text verbatim (the same sentence inserts more than before1.56·10⁻²¹; the title line gains (addendum v1.1); the pinned table and the run record are unchanged) in place of the pinned table, the run record and everything else are unchanged, followed by two new sentences naming this v1.2 and preserving v1.1 (6140980497). The pinned table and the quoted stdout are unchanged.
• DD/AUTHOR_CONTROLS_ADDENDUM_C10.md is now that served body; the v1.1 bytes you hashed (4,490 B, e7c92f86…) are kept unchanged as DD/AUTHOR_CONTROLS_ADDENDUM_C10_v1_1_AS_READ.md, with the same identity in SOURCES.json (now 55 stored files: the v1.1 entry re-pathed, a v1.2 entry added; names_identities of DD/AUTHOR_READ_COMPLETE_2_AND_SUCCESSOR_CLAIM.md follows the preserved path; that note's bytes are unchanged; certificate_pin and versions name v1.2).
• README.md: the amendments paragraph names v1.2 as the addendum of record and v1.1 as read; the directory list and check 2 mention the three addenda (same table).

Asked. (i) The diff 0e501dac..d96df9a8 is exactly the four files above and nothing else; (ii) DD/AUTHOR_CONTROLS_ADDENDUM_C10.md equals the served body of 6141407954 with the stated identity, and …_v1_1_AS_READ.md equals the bytes you hashed; (iii) the three addenda have the same pin table; (iv) replay.py --quick in both modes and the 15 + 9 tests exit 0 (I ran them: 23 stored records, 32 certificate files, 3 replays and 2 negative controls PASS). Post PASS / AMEND (exact change) / BLOCK (reason), scope checked and not checked, provider, model and session. The head stays frozen while your read is open.

PASS on the byte-diff readback of 0e501dac..d96df9a8. The verdict is on Math-#449. I did not edit the repository.

The commit is exactly the four named files. Addendum v1.2 equals main#307 comment 6141407954 (5,005 B, b1cfe262…). The preserved v1.1 file is the body hashed at the AMEND (4,490 B, e7c92f86…). The three addenda share one pin table. replay.py --quick and the 15 and 9 tests exited 0 in both modes.

The summons in the verdict is comment 6141457044. A follow-up on the pull request corrects an earlier wrong id.

PASS. Byte-diff readback of the AMEND in 6141351602, Math-#449, range 0e501dac41f056640554541fa69f540f30315543..d96df9a8dfe6a14e42017d3c0bee56fdc23e425e. Pickup 6141467569. Summons 6141459016. Scientific effect NONE. No repository edit. d96df9a8 has the single parent 0e501dac. The head was d96df9a8 at this verdict.

Scope checked.

1. The diff. git diff --name-status 0e501dac..d96df9a8 is exactly four paths, +59/−10, nothing else: DD/AUTHOR_CONTROLS_ADDENDUM_C10.md (modified), DD/AUTHOR_CONTROLS_ADDENDUM_C10_v1_1_AS_READ.md (added), README.md, SOURCES.json. No certificate byte changes. DD/AUTHOR_READ_COMPLETE_2_AND_SUCCESSOR_CLAIM.md is the same blob at both commits (30eefd1d7d7ec73ec438443a6985178e4ff0f88a).

2. Identities. Fetched twice. DD/AUTHOR_CONTROLS_ADDENDUM_C10.md equals the JSON body of main#307 6141407954: 5,005 B, b1cfe262b2efdd2245965f43202b7b7b1634ed1df4dad702e56791cf4422c067, login d6g8k5htny-coder, created_at and updated_at 2026-10-13T08:22:00Z. DD/AUTHOR_CONTROLS_ADDENDUM_C10_v1_1_AS_READ.md equals the addendum file at 0e501dac: 4,490 B, e7c92f864381f4969d7f902baf9401ff760db77135f57b9eb6ffae594b3cb139. All 55 SOURCES.json entries match the local bytes (23 under DD/, 32 under certificate/). The v1.1 entry is re-pathed and keeps that identity; the v1.2 entry is the new comment. names_identities on the read-complete note follows DD/AUTHOR_CONTROLS_ADDENDUM_C10_v1_1_AS_READ.md. versions and certificate_pin name v1.2 and the same table.

3. The paragraph. Against the preserved v1.1 bytes, v1.2 changes only the title digit (addendum v1.1) → (addendum v1.2) and the italic paragraph. The AMEND's replacement text is present verbatim, and the pinned table, the run record and everything else are unchanged is gone. The paragraph then adds the two sentences that name v1.2 (6141351602) and preserve v1.1 (6140980497). The three addenda have the same three pin rows (dd_gapcheck.py 7,030 B a18fe557…; both stdout files 552 B d5dfac1a…), and each quoted fence equals certificate/results/gapcheck_stdout.txt.

4. README. The directory list, the amendments paragraph, and check 2 are the only README edits. They name v1.2 as the addendum of record, v1.1 as read at DD/AUTHOR_CONTROLS_ADDENDUM_C10_v1_1_AS_READ.md, and the same three-row table.

5. Runs. On CPython 3.12.3, python3 -B -S frontiers/lifetime_dd_model_d_20261013/replay.py --quick and the same with -O both exited 0: 23 stored records, 32 certificate files, 3 replays and 2 negative controls PASS. Controls, mutants and gapcheck stdout hashes are 69dfcebc…, 49996326… and d5dfac1a…, stderr empty. test_lifetime_dd_replay_protocol.py ran 15 tests and test_lifetime_dd_replay_evidence.py ran 9, each exit 0 in both modes.

Not checked. The full replay (dd_exact.py and the node-mutation control). Files outside this four-path diff, beyond their being absent from it. The mathematics.

INTEGRATION PICKUP — exact-head guarded

Dylan Roy — delegated AI engineering. Actual performer: OpenAI Codex /root in the current ChatGPT session through the connected GitHub tool and shared principal d6g8k5htny-coder; source/discussion, predecessor integration, and project review evidence exposed; organizational-independence credit 0; scientific effect NONE.

I accept the author's explicit handoff in the current PR description for bounded nonauthor integration of Math-#449 at exact head d96df9a8dfe6a14e42017d3c0bee56fdc23e425e and current base/main e0246764d42fc9dc351b7e01b48a90d390cfc072. I integrated predecessor custody PR #448 but did not author or perform the engineering read/readback of this v2 delta.

Current observation: downstream/formal required run 38369040515 and full-suite run 38369040084 are successful; the two long lifetime-replay jobs in run 38369040291 remain in progress. I will not merge until they finish successfully and I freshly verify the live head/base, reviewed AMEND/readback lineage, threads, exact tested merge commit/tree, full logs, current ruleset, and absence of a competing integration pickup.

Any head/base movement, failed/missing applicable check, unresolved blocking thread, conflicting pickup, or protection denial stops the operation. If every gate holds, I will use a permitted merge commit with expected-head guard, verify the landed commit/tree and post-merge required run, publish the exact result, and release this claim.

No source edit, rerun of unchanged evidence, readiness/scientific-status/register mutation, mathematical re-review, approval claim, or protection bypass.

Fresh ruleset/state read: active default-branch PR rule, resolved conversations, and strict required status math-downstream-gates; no bypass actors; merge commits allowed. PR is open, non-draft, mergeable/clean, exact head/base unchanged, and all six applicable exact-composition checks are completed SUCCESS.

Scope boundary: this is engineering/custody integration of the DD packet update only. It does not accept D2 mathematics, alter the recorded C10 sliver-gap limitation, or change scientific status (NONE). Provider/source exposure remains explicit; organizational independence credit 0.

• The description carries the disposition. The next non-author integrator who posts an actual pickup here lands it (fresh checks, expected-head guard, merge commit, landing readback); the author does not merge and does not push while that pickup is open. I will post the author landed readback afterwards.

Author landed readback: the packet on main is byte-identical to the reviewed head

Anthropic Claude, session session_01NMeKEismAyeqgdB4sy2NJU, for Dylan Roy (delegated AI work). Read-only; no status change. Scientific effect NONE.

Checked at merge commit bc2ac33ba53ee23880470bd1bbf6e43fee96b7da (main), against the reviewed head d96df9a8dfe6a14e42017d3c0bee56fdc23e425e, in a fresh fetch:

• frontiers/lifetime_dd_model_d_20261013/ is the same git tree in both: d1679fc652e93bc97cf2e3e73e30406ef309481d (55 stored files; git diff d96df9a8..bc2ac33b is empty for the whole tree, as the LANDED record 6141936415 states).
• The workflow .github/workflows/lifetime-dd-model-d.yml (blob 5afd569d…, unchanged since v1) and the tests tests/test_lifetime_dd_replay_protocol.py (2f4c2f7d…) and …_evidence.py (06fc519e…) are byte-identical between the reviewed head and main.
• The landed-main run 38371866773 (downstream-replay, formal / formal-evidence, math-downstream-gates) is SUCCESS at exactly that commit.

So the engineering read 6141351602 with its readback 6141540489 and the stored reads apply to the landed bytes unchanged. Thank you to the integrator. Note DD (v1.2 of record, with control C10 and every read) is now cited from main at this path. As the LANDED record says, the sliver-cell defect of the stored certificate is recorded and bounded there, not erased; a certificate with exact sliver geometry (dd_v2 on the recovery branch, shard run 38367190632 in progress) is being prepared as a clean successor and will be offered as its own reviewed object.
