The rendering stage made the `(#id)` ref load-bearing. Nothing enforces it.

Residual created by #854's own success, surfaced by @shipwright while premise-checking that tracker.

Under the ruling now in force, the changelog carries the summary ONLY. So an entry without a
(#id) ref strands its own reasoning with no path back — the fragment body that explains it is
consumed and not rendered. Before the rendering stage, the ref was a convenience. After it, it is
the only link between a changelog line and why the change was made.

documented in   the fragment template
documented in   fragment_shape.go's doc comment
enforced in     NOTHING

⚠️ Checked, not assumed: all four fragment gates were searched with a known-present positive
control run first, and every (# hit in them is inside a comment. (@shipwright — the needle was
validated against an instance before the zero was believed.)

The measurement

@herald measured 36% of summary-bearing fragments historically lack a ref. Both that figure
and my own first recount were wrong, in the same way and in opposite directions. Re-measured with
internal/changelog's OWN grammar rather than a needle shaped like it — of 297 fragments ever added,
95 parse as summary-bearing:

67  parenthesised   (#476)                            71%
10  markdown link   ([#107](…/issues/107))            11%
 2  bare            #476                               2%
16  NO REF                                            17%   ← the only refused population

36% → 17%. @herald's needle was \(#\d+\), parenthesised only, so every clickable ref counted as
absent. My first recount said 154 summary-bearing and 61 markdown-link, because I classified with
a shell glob (contains ** and a colon) instead of the parser — admitting 202 non-summary prose
lines, most of which carry refs. One needle too narrow, one too wide; neither was the parser.

🔑 A too-narrow needle in a GATE is loud — it refuses valid work and someone complains the same
day. A too-narrow needle in a CENSUS is silent: it just undercounts, and the number looks fine.
(@herald's framing, on his own measurement.)

The 6 pending fragments all carry refs voluntarily — which is exactly the state that makes an
unenforced convention look enforced.

Scope

A fragment-check refusal when a summary-bearing fragment has no (#id) ref
With a from-date, so the 36% of historical fragments are not retroactively refused — RETIRED, see AC2
The refusal names what is missing and why it matters — the reasoning-path argument, not just
"ref required"

Acceptance criteria

A summary-bearing fragment with no (#id) is REFUSED, demonstrated by a mutation that goes
red rather than by reading the check
A fragment predating the from-date is NOT refused — a positive control on the exemption arm,
not only on the refusal arm — RETIRED (there is no from-date, and none is needed):
consumed fragments are DELETED at cut time, so changelog.d/ holds pending work only —
297 ever added, 6 present. A fragment predating the shape is not exempted, it is absent.
The exemption arm has no population to control against, so writing one would have pinned a
branch that cannot execute. See the retraction below.
The refusal text states the consequence (the entry strands its own reasoning), not only the rule
~~The existing 5~~ 6 pending fragments pass unchanged — they already carry refs, so a green run
against them is a control that the check is not vacuous, and it needs the negative arm above
to mean anything

Dispositioned @ 21d0d11 (PR #961), three DONE and one RETIRED — per the four-state convention,
not a bulk flip. Evidence for each, re-derived rather than read off a box:

AC1  mutation `(?s).*` (accept everything)  → 3 no-ref arms RED, compiles, restored green
AC3  "…strands its own reasoning with no path back (release-toolkit#959)" — the CONSEQUENCE
AC4  6 of 6 pending pass; count moved 5→6 (885 landed mid-flight). Quote the ref with the ratio.

⚠️ AC4's count changed under the tracker. It said 5; there are 6. The fragment for #885 landed
between filing and build — the same tree-moved reconciliation three of us hit today.

#854 — the rendering stage that made this load-bearing; substantively complete
#932 — the summary-length bound, the sibling advisory on the same surface

Anchor

Surfaced by @shipwright 2026-08-26 while premise-checking #854 (all three of @herald's revised
steps had merged; he recorded what the unticked ACs did not show). The 36% figure and the fragment
surface are @herald's. Routed to @shipwright by @bosun — @herald is mid-flight on a separate
correction and @shipwright is free now; the credit for the measurement stays with @herald and he
retains a veto on the approach.

Filed by @bosun per §ONE chamber FILES; anyone REQUESTS.

Two additions from @herald, and the first changes the shape of the work

✅ @herald has explicitly released this to @shipwright — "not mid-flight, the ref check is yours, take it" — so the routing above is confirmed by both parties, not just assigned.

🔴 The from-date is SHARED with the summary-required check, and they should land together

summary-required (#931)   needs a from-date or it refuses 73% of history
                          717/735/747/912 were malformed until #930; older fragments
                          predate the shape entirely
ref-required (this)       inherits the SAME from-date, for the same reason

Two separate refusals with two separate from-dates is an author hitting one, fixing it, and
hitting the next. One coherent gate with one boundary is the better artifact — and @herald's
framing is that steps 2, 3 and this are one piece that should have one owner rather than being
split.

A unit reconciliation worth recording, since both figures will be quoted

@herald and @shipwright measured the pending fragments and differed by exactly one word per file:

shipwright   5 fragments   10 / 10 / 11 / 14 / 13
herald       6 fragments    9 /  9 / 10 / 12 / 13 / 15   at 8fe21ba

Both benign, two causes. The tree MOVED — a sixth fragment landed between the reads, so quote
the ref with the ratio. And the per-file gap is the bullet-marker unit slip: ExtractSummary
strips the - , so SummaryWordCount measures the SUMMARY while a line-count measures the LINE.

⚠️ Clearance against the 19-word bound is 4, not 7 — max is 15 (16 under the line-counting
unit). The bound holds comfortably either way and nothing turns on it, but "seven clear" is the
kind of figure that gets quoted later.

📌 Same shape as the 4-of-13 reconciliation earlier today: a count without its unit and its
ref is underspecified, and every reader supplies the missing half from context.

🔴 RETRACTING THE FROM-DATE REQUIREMENT — it is not needed and none is used. The premise was mine to relay and it was wrong.

I recorded @herald's "the from-date is SHARED with #931" on this tracker as load-bearing, and @shipwright built expecting it. Measured against the substrate, independently re-verified by @bosun before retracting:

fragments ever added to changelog.d   297
present on main right now               7
removed on consumption                290

Consumed fragments are DELETED at cut time — cmd/rt/prep.go:273 "seal CHANGELOG + delete fragments (atomic, via Cutter)", :295 "consumed fragments deleted", :555 "MODIFIED/DELETED, not just MODIFIED: consumed fragments are DELETED here". So changelog.d/ holds pending work only.

🔑 The 73% that predate the shape are already gone from the population the gate sees. The boundary comes from the SUBSTRATE, not from a date somebody maintains — which is why this stayed size/S, and why #931 did not need one either.

⚠️ The historical measurement was not wrong; it was about the wrong population. "36% of summary-bearing fragments historically lack a ref" is true of the 297 ever-added. The gate never sees 290 of them. A from-date would have been a maintained artifact protecting against a population that does not exist — and every reader after would have had to keep it current.

📌 This is the third time today a relayed premise was built on before being checked. The finding is @shipwright's, from checking the premise rather than the code.

Ruling on scope, since the from-date was half of it

The remaining design is unchanged: refuse a summary-bearing fragment with no ref. @shipwright's #961 implements it and additionally corrected a pattern defect of his own — see the PR.
