Review fixes from the cold adversarial pass on PR #411. Verdict was MERGEABLE, but one
HIGH is a genuine defect worth the round-trip.
[decisions-edit] rationale: the 12 "modified" lines in docs/decisions.md are lines THIS PR
added in its own previous commit (e33205e8), not a settled entry on main. The hook diffs
against HEAD; net against origin/main this file is still a pure insertion (65 added, 0
deleted -- verified, and CI's decisions-guard diffs against the PR base). It is also the
sanctioned reason regardless: the entry as first written contained a factual error (see
HIGH below).
HIGH -- `--memory=2g` alone silently grants 2g of SWAP as well. Docker defaults an unset
--memory-swap to 2x --memory. Verified live on bumblebee: `--memory=2g` alone gives
memory.max=2147483648 AND memory.swap.max=2147483648; adding `--memory-swap=2g` gives
memory.swap.max=0. Capping RAM while permitting swap is close to the worst outcome on the
one host whose swap thrash is the entire reason for the cap -- and a swapping mysqld
mid-DDL is exactly the pathology behind the known `Command Timeout expired` migrations
flake, so the naive cap could have made that flake worse rather than better. The comment
promising "if this ever OOM-kills the service" described a failure mode that would not
have happened first: it would have swapped, silently. Now --memory-swap=2g (swap off);
prefer a loud OOM over silent degradation.
The same 2x applies to the runners' 10g job slots (10 GiB RAM + 10 GiB swap each), which
is a plausible direct mechanism for the incident's 21 GiB swapped. That is #604's
boundary -- reporting it there.
MEDIUM -- `if: always()` does not make a step advisory. It controls whether the step RUNS,
not whether its failure fails the job, and defaults.run.shell: bash means -e is on, so a
failed cat/redirect in an informational step could redden a green test job. Use
continue-on-error: true, matching the neighbouring Coverage summary step.
MEDIUM -- the peak step must run LAST. memory.peak read at step N reports the peak only up
to N, so sitting before Coverage summary excluded reportgenerator's memory -- under-
reporting the very number #604 sizes caps on. Moved after it.
LOW -- dependency-scan.yml gets the env too; workflow env does not cross workflow files,
and that one runs unattended on a cron against the prod media host.
NIT -- Dockerfile ENV moved below the openapi-generator wget: an ENV invalidates every
layer under it, and that ~30MB download is deliberately ordered early to stay cached
(#190). Nothing between it and restore compiles, so this placement is free.
NIT -- docs no longer imply this shrinks `format`. dotnet format loads Roslyn in-process
via MSBuildWorkspace and never spawns csc, so its 3.95 GiB is untouched; sizing the small
lane on the assumption it shrank would be a trap.
Also record honestly that 543 MiB is init+idle rather than the 787-migration replay (so 2g
is a measured floor + headroom, not a measured ceiling -- the migrations job going green
is what validates it) and that --cpus=2 is judgement with no measurement behind it. The
entry criticises dressing estimates as measurements; it should not do that itself.
