From an open-issue review. Not an issue fix — a finding the review turned up
outside the queue.

Both discussions asked for two quantities, and #65 has since sourced one of
each. Left as they were, a curator reading them would go looking for work that
is already done.

discussion done since still open
divisome_complex#ring_dimensions_unsourced FtsZ filament length 40–160 nm, diameter ~5 nm — both with verbatim snippets Z-ring radial thickness
type_iii...#needle_dimensions_unsourced channel diameter ~2.5 nm, filament width ~6 nm, base diameter ~25 nm needle length

Neither remaining half is an oversight:

  • The review reports the Z-ring's radial thickness only negatively — it did
    not increase even under FtsZ overexpression — and gives no figure. The ~13 nm
    THICKNESS on the record is the filament-to-membrane spacing, a different
    quantity, and its evidence notes already say so.
  • The source says only that the needle "protrudes several nanometers from the
    bacterial surface"
    . That was deliberately not turned into a number.

Both rationales now record why the other half closed, so the narrowing is
auditable rather than looking like the question quietly shrank.

just qc passes.

An open-issue review found both discussions asking for two quantities each, one
of which #65 has since sourced. Left as they were, they would send a curator
after finished work.

  ring_dimensions_unsourced   "FtsZ filament length and Z-ring thickness"
    filament length 40-160 nm and diameter ~5 nm now carry verbatim snippets.
    The Z-ring's radial thickness does not: the review reports it only
    negatively -- it did not increase even under FtsZ overexpression -- and
    gives no figure. The ~13 nm THICKNESS on the record is the
    filament-to-membrane spacing, a different quantity, as its notes say.

  needle_dimensions_unsourced  "needle length and channel diameter"
    channel diameter ~2.5 nm, filament width ~6 nm and base diameter ~25 nm now
    carry verbatim snippets. The length does not, because the source says only
    that the needle "protrudes several nanometers" and gives no figure. It was
    deliberately not estimated from that phrasing.

Both prompts now name only what is missing, and both rationales say why the
other half is closed so the narrowing is auditable rather than looking like the
question shrank on its own.

just qc passes.

Copilot was unable to review this pull request because the user who requested the review has reached their quota limit.

Self-review of the previous commit found it had replaced each discussion's
rationale rather than adding to it, and the deleted text was the more valuable
half:

  A first pass added filament length and ring thickness attributed to McQuillen
  & Xiao 2020 without reading it; both were removed (#91).

  A first pass added ~45-80 nm needle length and a ~2-3 nm channel attributed to
  Deng et al. 2017 on the strength of its title alone.

That is the record of specific numbers fabricated from paper titles and the #91
removal that followed -- the institutional memory that stops the mistake
recurring -- and it was overwritten with "Narrowed after #65". The schema says
rationale is "why this matters", which the original answered and the replacement
did not.

Both rationales are restored byte-identical to main. The narrowing moves to
`notes`, which the schema provides and neither discussion was using (#179).

posed_date is restored to 2026-08-31 (#180). It records when a question was
raised; narrowing does not re-raise it, and moving it forward made a question
open since 31 August look two days old -- backwards for a field whose only use
is showing how long something has sat there. The value written was not even the
edit's own date.

docs/CURATION.md now states how a discussion's fields age: prompt may be
narrowed, rationale is appended to and never replaced, notes holds current
state, posed_date never moves, and issue links belong in `evidence` (#181, left
open as a sweep).

just qc passes.

Closes #179
Closes #180
