fix(cover): fill {{RECIPIENT_BLOCK}} so pack cover templates render - #4043
fix(cover): fill {{RECIPIENT_BLOCK}} so pack cover templates render#4043rubicon wants to merge 2 commits into
Conversation
A cover template built to the pack authoring contract could not be rendered at
all. The contract lists {{RECIPIENT_BLOCK}} among the required slots and places
it bare, expecting the filler to wrap itself, but generate-cover-letter.mjs had
no fill path for it, so every such template hit the unresolved-placeholder guard
and the render died.
Core was self-consistent, which is what kept this hidden: the replacements map
holds 14 entries, the shipped cover-letter-template.html uses 14 slots, and the
two sets match exactly in both directions. Nothing in core had a reason to fill
a 15th. Packs ship their own filler for preview generation, so pack previews
rendered correctly throughout.
The sharper half is the gate. validateTemplate requires only NAME, ROLE_TITLE
and OPENING for kind=cover, so a pack cover template passes validation and then
fails in the substitution pass. Same shape as career-ops-hq#3775 on the CV side.
buildRecipientBlock returns a complete <div class="recipient"> or an empty
string, one <div> per line rather than a <br> join, matching what the packs' CSS
targets. It accepts address_lines and also a plain address string. A partial
recipient renders as far as it goes, because a company with no named individual
and a name with no street address are both ordinary. Only an empty or absent
recipient yields "", so a letter with no addressee still renders instead of
trading one hard failure for another.
templates/cover-letter-template.html and buildDateline are deliberately
untouched; both are separate design questions rather than part of this bug.
Closes career-ops-hq#4042

Verified the owned test by execution and mutation. It is sound.
tests/cover-recipient-block.test.mjs imports the real buildHtml from generate-cover-letter.mjs and drives the actual template-fill pipeline: it writes a pack template carrying {{RECIPIENT_BLOCK}}, calls buildHtml, and inspects the rendered HTML. It asserts content, not just token absence: every supplied recipient part reaches the output (name, title, company, street, city line) and no literal {{RECIPIENT_BLOCK}} remains, plus the structural wrapper and HTML-escaping of the recipient payload, and the no-addressee and empty-recipient cases render rather than throw. I mutation-checked it two ways: reverting the fix (dropping the map entry, reproducing the original unresolved-placeholder throw) reddens all five, and a blanket strip (mapping the token to an empty string) still reddens the content and wrapper cases. So it cannot be satisfied by simply deleting the token.
Sound on the test axis. generate-cover-letter.mjs is the maintainer's call on the substance.
filter(Boolean) keeps " ", so a recipient whose fields were all spaces rendered a <div class="recipient"> full of blank divs: a visibly indented gap above the Re: line, on a letter that has no addressee at all. Trimming before the filter drops those fields, and a recipient left with nothing usable now returns "" like an absent one. The existing empty-object test passed without this, which is what made it easy to miss. Two cases are pinned now: an all-whitespace recipient emits no wrapper, and a partially blank one keeps only its real lines rather than being dropped wholesale. Both confirmed red against the untrimmed function and green after.

Re-checked after the head moved. The new commit treats a whitespace-only recipient field as absent: buildRecipientBlock now trims each field before filter(Boolean), so an all-whitespace recipient drops to an empty block instead of rendering a wrapper full of blank divs (the indented gap above the Re: line), and a fully-blank recipient yields no wrapper at all. Two tests were added for exactly those cases.
The owned test still drives the real buildHtml through the pack template carrying the bare {{RECIPIENT_BLOCK}} slot, and still asserts real recipient content reaches the output (name, title, address lines) plus the wrapper structure and escaping, not just token absence. 7 tests pass. I re-ran the mutations: reverting the fix (dropping the map entry so the placeholder throws) reddens everything, and a blanket strip (mapping the token to an empty string) still reddens the content, wrapper, partial-blank, and escaping cases, so it cannot be satisfied by simply deleting the token.
Sound on the test axis at this head. generate-cover-letter.mjs is the maintainer's call on the substance.

node test-all.mjsand all tests passWhy it was invisible
Core is entirely self-consistent here, which is what kept this hidden. The
replacementsmap holds 14 entries, the shippedtemplates/cover-letter-template.htmluses 14 slots, and the two sets match exactly in both directions. Nothing in core had a reason to fill a 15th slot. The gap only appears for a template built to the published pack contract, and packs ship their own filler for preview generation, so pack previews rendered correctly the whole time.The sharper half is the gate.
validateTemplaterequires onlyNAME,ROLE_TITLEandOPENINGforkind=cover, so a pack cover template passes validation and then fails in the substitution pass. That is the same shape as #3775 on the CV side: a template satisfying the published contract, waved through by the validator, dying because core fills fewer slots than the contract promises.The change
One function and one map entry.
buildRecipientBlockreturns a complete<div class="recipient">or an empty string, because the contract places the placeholder bare and expects the filler to wrap itself. Each line is its own<div>rather than a<br>join, which is what the packs' CSS targets. It acceptsaddress_lines(the contract's shape) and also a plainaddressstring.A partial recipient renders as far as it goes. A company with no named individual, or a name with no street address, are both ordinary states for a cover letter. Only a recipient with nothing usable in it, or no recipient at all, gives the empty string, so a letter with no addressee still renders rather than trading one hard failure for another.
Deliberately not in this change
templates/cover-letter-template.htmlis untouched. Adding the slot to core's own shipped letter would change core's output, which is a design decision rather than part of this bug.buildDatelineis also untouched. It joins company, city and date, and under the pack contract the company lives in the address block, so a pack letter prints the company twice. Gating that join onletter.recipientwould fix it and keep every existing payload byte-identical, but it is a separate behavioural question and I did not want to argue two things in one PR. Happy to follow up if you want it.Verification
tests/cover-recipient-block.test.mjs, five tests, confirmed red on the unfixed tree first (5 failed, 0 passed) and green after. They pin both halves: the slot fills with the contract's shape and escaping holds, and an absent or empty recipient renders nothing without erroring.node test-all.mjs --quick: 8688 passed, 0 failed. The five cover suites together: 16 passed, 0 failed.Summary
