editions — series-level memory for long-form

Two stores, one package, both about what a series knows rather than what an edition knows: the distillate (N11) — what the reader has already been told — and the register (N12) — what is in production right now and how long it is taking.

1. Series distillate (N11, serie-nivå-vern)

Every long-form gate agent sees one edition. At two editions a week the fastest- growing defect class is not a bad edition — it is a repeated one: the anecdote, the argument or the hook the reader already met three editions ago. That failure is structurally invisible today, and the specifics-bank dedupe actively encourages re-surfacing the same material.

So each locked edition leaves behind a distillate of the narrative units it spent, and the Step 2.5 skeleton gate checks the next skeleton against it — before prose exists, the only point where changing course is still cheap.

Where the distillate lives

<serie>/linkedin/series-distillate.json — beside edition-state.json in the series root, not in the per-user data dir. It is series-scoped state, the series folder is already where the edition's state lives, and putting it there means it travels with the series and needs no slug→path map.

Series-scoped is the point: this answers "has this reader heard it?". Cross-series re-use of the operator's raw material is a different grain, tracked by the specifics-bank's usedIn log.

Setup

cd scripts/editions && npm install

Use

# Step 8 (lock): fold the edition's spent units into the series distillate
node --import tsx src/cli.ts distil-append \
  --distillate "<serie>/linkedin/series-distillate.json" \
  --series seres --extract "<abs>/extract.json"

# Step 2.5 (before prose): check the proposed skeleton against everything published
node --import tsx src/cli.ts distil-check \
  --distillate "<serie>/linkedin/series-distillate.json" \
  --skeleton "<abs>/skeleton.json" [--threshold 0.4] [--json]

extract.json = {editionId, title, lockedAt, anecdotes[], arguments[], hooks[]} — the AI extract from the locked edition. skeleton.json = {anecdotes?, arguments?, hooks?}.

Exit codes: 0 on success — including a REUSE verdict. The check is advisory by design (it reports into the annotation gate the operator already reads at Step 2.5), unlike the binding gate's BLOCK. 2 on usage error.

Model

• Extraction is AI, comparison is code. The command layer distils the units from the locked prose; the store, the similarity and the verdict are plain deterministic code — no model in the loop, no run-to-run variance.
• Similarity = character-trigram Jaccard, not word overlap. The plugin is language-general and the languages it is used in are inflection-heavy: migrere / migreringen are the same unit to a reader but different word tokens. Calibrated against real paraphrase pairs (see tests/distillate.test.ts): retellings score 0.44–0.55, unrelated material 0.04–0.06, same-topic-different-story 0.24 — so the default threshold sits in the gap at 0.40. Word-Jaccard scored a shortened hook paraphrase at 0.11 and would have let it through.
• Units are compared within their kind. An argument re-used as a hook is a new move, not a retread.
• A re-locked edition replaces its entry, never duplicates it — /linkedin:pivot re-opens and re-locks the same edition, and the reader still only met it once.
• A missing distillate is not an error. A series' first edition compares against nothing and is CLEAR.

2. Editions register (N12, A1-11 / A1-12)

Two things were structurally invisible before this: which editions are in flight (readable only by opening every series folder's edition-state.json by hand) and how long an edition takes (not recorded anywhere at all). At a two-editions-a-week cadence both are load-bearing — you cannot dimension a production line on numbers you never collected.

So every phase transition in /linkedin:newsletter runs one command that does two writes: it appends {phase, completedAt} to articles.NN.phaseLog in the edition-state, and mirrors the edition's row into the register.

# at EVERY phase transition (after currentPhase has been written)
node --import tsx src/cli.ts register-upsert \
  --edition-state "<serie>/linkedin/edition-state.json" \
  --next "Step 3a — spine prose" [--slot "2026-07-28 07:45"] [--path <series-root>]

# the week's work-in-progress, without opening a single series folder
node --import tsx src/cli.ts register-list [--all] [--json]

# at Step 10, once the edition is scheduled — prints the measured lead time
node --import tsx src/cli.ts register-complete --series seres --edition 05

Where the register lives

${LINKEDIN_STUDIO_DATA:-$HOME/.claude/linkedin-studio}/editions/register.json — the per-user data dir (M0 convention), because it spans all series and must survive plugin upgrades and reinstalls. Contrast the distillate above, which is per-series and therefore lives in the series root.

Model

• The register is a MIRROR, never a source of truth. Every row is derived from an edition-state.json at a transition. Resumption reads edition-state and nothing else; delete the register and the next transition rebuilds the row. Losing it costs telemetry, not an edition — so a failed register-upsert is reported, never a reason to stop the pipeline.
• One call, both writes. A phase log the command layer had to remember to append separately would be incomplete inside a week, and an incomplete log measures nothing.
• No clock in the core. Every mutation takes now as an argument (--at / --now at the CLI edge), exactly like the distillate takes lockedAt. Deterministic tests, no hidden timezone behaviour.
• startedAt never moves. It is the lead-time anchor: re-upserting a completed edition reactivates the same row (that is what /linkedin:pivot does), so the measured time reflects real elapsed production rather than restarting the clock.
• Idempotent where a re-run is legitimate, not where it is real work. Repeating the same transition logs once; a phase that recurs after another one is logged again, because a pivot back through cleared gates is production time that actually happened. Completing twice keeps the first completedAt.
• Missing facts are errors, not defaults. A row naming the wrong phase is worse than no row — the whole point is that the list can be trusted without opening files. Only the title is allowed to be empty; it is telemetry, not a gate.

Test

npm test      # node:test, deterministic (callers supply lockedAt)
npm run build # tsc — must stay clean
