docs(tox): the catalog-construction claim was 5x, not "dominates" - #108
Merged

Conversation
The baseline was keyed on ABSOLUTE paths with the leading slash removed:
home/matt/qc/ferric/crates/ferric-cc/src/ccd.rs::ccd@24
`rust-code-analysis-cli` mirrors each input's absolute path into its
output tree, so `os.path.relpath(fpath, tmp)` recovers the absolute
path, not a repo-relative one. All 6104 baseline keys carry one
checkout's directory.
Consequence: the gate is unusable in any git worktree. Every function
looks NEW, so every push is measured against the bare
NEW_FUNCTION_CC_CEILING instead of against its own recorded history --
and it fails on changes that touch no Rust at all. This was found by a
commit whose entire diff was one `.config/nextest.toml` file.
Fixed by stripping ROOT from the recovered path. Keys are now
crates/ferric-cc/src/ccd.rs::ccd@24
which is portable across worktrees and machines -- the same reasoning as
[[never-commit-machine-specific-values]].
The baseline itself still holds the old keys and must be regenerated in
the MAIN checkout (`python3 scripts/complexity_gate.py
--update-baseline`), so the diff is reviewable rather than encoding a
worktree path. Doing that separately, because it also surfaces a real
regression the path bug was masking: solve_rhf is CC=176 and
solve_uhf_fockmod CC=153, both above the 150 ceiling, both grown in #88
(TRAH/AURORA). That is a genuine signal and deserves its own change, not
a silent re-baseline bundled in here.

Mechanically required by the previous commit: all 6104 keys were
absolute paths, so the file had to be regenerated once they became
repo-relative. 7211 functions, 0 keys starting with "home/".
What this BAKES IN, stated so it is visible in review rather than buried
in a 7000-entry diff:
crates/ferric-scf/src/rhf.rs::solve_rhf@753 CC=176
crates/ferric-scf/src/uhf.rs::solve_uhf_fockmod@360 CC=153
Both exceed NEW_FUNCTION_CC_CEILING (150). Both grew in #88
(TRAH/AURORA-SCF), and the path bug is precisely why that landed
unnoticed -- with no key matching, the gate never compared them against
their own history. The script's own header still reads "solve_rhf,
CC=134", which was true when written.
They are NOT fixed here. Recording them is the honest move: the gate is
live again, so any FURTHER growth in either function fails a push, and
simplifying two SCF drivers is not a gate fix.
MUTATION TESTED: lowering solve_rhf's baseline entry to CC=10 makes the
gate report "CC 10 -> 176 (+166)" and FAIL, so it is live rather than
passing vacuously.

`RdkitAlertsProvider`'s docstring said building the FilterCatalog objects
is "slow enough that per-molecule construction dominates the runtime of a
batch". MEASURED while costing the pipeline's cheap stages
(danuglipron, min of 3-5 reps, single-threaded):
construction 47 ms ONE-OFF
fetch 9.4 ms / molecule
ratio 5x
So per-molecule construction would cost a batch ~6x. Real, worth
avoiding, and not "dominates".
Building once is still clearly right, so the CODE does not change. The
reason does. An overstated justification is worse than none: it survives
into other decisions, and someone budgeting a batch from this sentence
would have over-provisioned by orders of magnitude.
tools/tox: 16 tests pass.

Retargeted to #104's two commits (the complexity-gate path fix and its re-baseline) are already in this branch, so the diff is unchanged by the retarget; it just makes CI actually run. If #104 merges first, git will drop the duplicates on rebase. |

Qualify the “~6x” batch claim.
For a batch of N molecules, reuse costs 47 + 9.4N ms, while per-molecule construction costs 56.4N ms. The ratio approaches 6x only for large batches. State the batch-size assumption or include the cost formula to avoid overstating the measurement.

Stacked on #104. Retarget to

RdkitAlertsProvider's docstring says building the FilterCatalog objects is "slow enough that per-molecule construction dominates the runtime of a batch."MEASURED (danuglipron, min of 3–5 reps, single-threaded):
fetchSo constructing per molecule would cost a batch ~6×. Real, worth avoiding — and not "dominates".
No code change. Building once is still clearly right; only the reason is wrong. An overstated justification is worse than none, because it survives into other decisions: someone budgeting a batch from that sentence would have over-provisioned by orders of magnitude.
