Stdio MCPL children now get DISCORD_SUPPRESSED_REACTIONS_BASELINE defaulted to every reaction the framework places (refusal markers, the default and configured awareness emoji, and retained outbox marks), derived at each spawn, so the framework's own marks don't come back to the agent as reaction events. An operator's own value with tokens still wins, and an awareness ledger that can't be read refuses the spawn rather than giving a partial default.

Problem

The protective reaction default covers refusal markers but misses configured awareness markers and emojis retained by offline recovery. #95 documents this coverage gap. Host composition also happens before the framework knows its effective awareness state.

Changes

• Add framework.getPlacedReactionBaseline(): refusal markers, default Discord awareness, configured awareness, and retained outbox emojis, deduplicated in a fresh snapshot. It returns suppression tokens: recognized composite custom-emote markers become stable bare IDs, and stored marker values and reaction payloads stay intact. An unreadable ledger throws rather than producing a partial default.
• Inject that default using the same transport selector as connection construction, including command+URL configs and explicit transport choices.
  • It is derived at each spawn. That covers the first connect, every automatic reconnect and a stub's retry, so a marker retained since the last spawn reaches the next child. The child's env is read through a getter at spawn; the caller's config stays unchanged.
  • An unreadable ledger never yields a partial default. Every connect reads the ledger first. A runtime connect refuses before it registers or spawns anything, and a startup connect, whose routing is staged beforehand, before anything spawns. Every runtime restart refuses before it stops the running child, whatever the server's baseline or transport, since the connect that follows reads the ledger at its awareness barrier anyway. An automatic reconnect of a child that takes the default fails and retries rather than spawn it without the default.
  • A declared or intentionally inherited value with tokens wins, and the framework logs at connect that it replaces the default. A value with no tokens, as discord-mcpl's parser reads them, counts as unset. The parser splits on commas and keeps a token only when normalizeReactionEmoji leaves something of it, after it strips U+FE0F, trims, and strips one leading and one trailing colon. So a blank value, commas alone, :, :: or a lone U+FE0F has no tokens (say from ${A},${B} or :${NAME}: with the variables empty), and the adapter reads it as suppression off; the framework applies the same steps. A blank inherited variable used to turn the protective default off that way. This reverses the earlier "including empty strings". The adapter's filters file and legacy operator env still take precedence, and they are where an operator turns suppression off. A null counts as unset too. Any other non-string value, such as a number from a JSON config, is read as its string form, as the child sees it, rather than failing the connect.
  • Windows matching also covers case-sensitive Worker env copies. Duplicate spellings resolve, within each source, to the first in sorted order, as Node's spawn keeps it. Then declared values take precedence over inherited ones.
• Suppression is by emoji, so members' own reactions with 💤, the configured awareness emoji or a retained recovery emoji stop reaching the agent too, as members' 🛑 already did.
• A refusal category named like an inherited property (constructor, toString) takes the 🛑 fallback instead of reaching Object.prototype.
• Preserve the refusal-only export and document the host cutover and separately managed WebSocket environments.

Tests

Main merged, and rounds from internal review (97a8483, ffb39ee, deb888c, adff8a2, 8ef10bc)

97a8483 merges main c2f9bae; its one conflict was an import line in src/framework.ts. An internal review of the sweep round as it merges onto main raised two places where a rule didn't match what it protects:

• A value of commas alone replaced the default. The blank check let ',' and ' , ' through, though discord-mcpl reads them as no tokens. ffb39ee counts a value with no non-blank token as unset.
• A restart of a server with its own baseline stopped its child and then failed. The restart read the ledger first only when the server took the default, but every runtime connect reads it at its awareness barrier. On a corrupt ledger, such a restart stopped the running child, failed its connect and left the server down. ffb39ee reads the ledger before every restart's disconnect.

A second review, of that fix, found the same at the connect: a reconnecting server with its own baseline (or a WebSocket one) was registered, refused at the barrier and left as a closed stub that blocked a retried connect. deb888c makes the ledger read the first thing every connect does. adff8a2 corrects the text for startup, which stages routing before it connects.

A third read found the no-token rule still narrower than the adapter's parser. discord-mcpl's normalizeReactionEmoji also strips one leading and one trailing colon, so : and :: are no tokens there, and :: is what its documented :name: form gives with an empty variable. 8ef10bc applies the parser's steps in its order. Its ledger-refusal tests now match the accounting error's category rather than the read's "ledger" label, so each fails where its claim breaks: a connection or config left registered, or the running child gone.

• New tests:

  • commas alone, declared and inherited, count as unset;
  • :, ::, ::,::, : , ::, a lone U+FE0F, and U+FE0F followed by : count as unset, declared and inherited; :sigil:, sigil, 🟪, a bracketed custom emoji and ::: stay the operator's;
  • a restart on a corrupt ledger, of a server with its own baseline, refuses and its child still answers;
  • a connect on a corrupt ledger, of a plain server or a reconnecting one with or without its own baseline, leaves neither a connection nor a config registered;
  • the Windows cases also run the composed env through buildChildEnv's win32 merge (fix(mcpl): preserve child CA bundle and proxy settings #205, now on main) and check what the child gets;
  • the custom-marker table checks both forms at 16, 17, 20 and 21 digits.

• Red first, 8ef10bc's tests on each earlier round's source, each failing where its claim breaks:

  • on adff8a2's: the six new no-token values, each passed to the child as the operator's value;
  • on ffb39ee's: those six, and the connect refusal at "no config is left registered";
  • on 97a8483's: those six and the two comma cases, the own-baseline restart at "the running child still answers", and the connect refusal at "no config is left registered".

  The sweep round's tests on 96940cd's source with main merged still fail the 11 listed below.

• Each piece removed (34 mutations of the compiled framework at 8ef10bc, one at a time): all caught by the three baseline files, which pass 60/60 unmutated. Those added since the last push:

  • the connect's ledger read removed, or moved after the registrations (before or after addServer), each of which fails at "no config is left registered";
  • the connect's ledger read limited to servers taking the default again, which fails at "no connection is left registered";
  • the restart's ledger read limited the same way;
  • commas, colons alone or a lone U+FE0F counted as a token;
  • each of the parser's steps after its first trim taken out alone (taking out the first changes nothing, since the trim after the U+FE0F strip does its work), and its colon strip widened to every leading and trailing colon;
  • each custom-marker form's bounds moved alone.

• Full suite on the VPS at 8ef10bc, one node --test --test-force-exit process per file, then CI's unforced step:

  • Node 20.20.2: 1728/1728 across 134 files. Main c2f9bae: 1671/1671 across 132. The difference is this PR's three files: placed-reaction-baseline (49) and reaction-baseline-platform (7) are new, and refusal-reaction-baseline has 4, against main's 3.
  • Node 24.21.0: 1724 counted. --test-force-exit cut history-module-realstore to 24 of 28; alone and unforced it passes 28/28, as do mcpl-tool-lifecycle (31/31) and placed-reaction-baseline (49/49). Main counted 1664 there, with history-module-ux cut to 19 of 26.
  • CI's unforced step (stop-with-work-in-flight, conversation-routing) passes on both.

Earlier reviewed head 327080a

• Build and typecheck pass.
• Full compiled suite: 1120 pass / 0 fail / 0 skipped with node --test --test-concurrency=2 --test-timeout=60000 --test-force-exit dist/test/*.test.js. Main 03c31d9 baseline: 1101/0/0, using the same command without the timeout flag and the same published dependencies (membrane 0.5.86, context-manager 0.11.0, chronicle 0.4.0; Node 24.19.0).
• An initial full run stalled in the existing coalescing file and was terminated. That unchanged file passed 66/66 in isolation; the bounded full retry above completed. The first stall's cause was not established.
• Internal independent re-review by Wren (Astra) of 327080a: no blocking findings; separate build and baseline/platform/child-env tests passed 23/23 without force-exit. Wren's original host paired review passed 9/9 and typecheck.
• Regressions fail before their fixes: initial baseline suite 4 pass / 7 fail; declared Windows cases 1/2; inherited-only cases 4/1; mixed-transport set 17/2. Final focused set: 23/23.
• Real stdio children verify startup, runtime connect/restart, retained recovery choices, override precedence, and timezone in the host pair.
• Host companion with initial AF d70e6e7: full 891/0 versus clean host main 888/0 with the same AF dependency. Its focused pair was rerun with AF 327080a: 9/0. The default test fails on published AF 0.19.0, exposing the release prerequisite.

Maintainer follow-up 96940cd

Weft's public approval included firsthand full-suite and Discord-consumer checks, plus two asks. Both are corrected: Windows duplicate-source selection follows the inspected Node24 spawn rule, and configured/retained composite custom markers map to stable IDs. Main df97a85 is merged without rewriting reviewed history; the release note is a unique fragment rather than a shared CHANGELOG edit.

• Full compiled suite at 96940cd: 1149 pass / 0 fail / 0 cancelled / 0 skipped, using the same bounded Node24 command above; current main df97a85 is included.
• Red regression set: 19 pass / 8 fail across 27 cases. Final baseline/platform/outbox/child-env set (including one additional bare-animated control): 38/38; build/typecheck pass.
• Internal exact-head review by Wren: no blocking findings; independent rebuild and 38/38 without force-exit, plus four custom forms through real DiscordFiltersState pinned at 6f38d13.
• My separate three-form Discord-consumer round-trip: 0/3 before → 3/3 after; same-ID renamed reactions suppress, same-name/different-ID reactions remain distinct, Unicode and explicit file/legacy overrides retain their behavior. This exercises the consumer implementation, not live Discord.
• Composed with fix(mcpl): preserve child CA bundle and proxy settings #205 head 038e06b in temporary tree 95c7db0: clean merge, compiled 39/39, plus 9 injection-to-child-env cases. Windows platform/env is simulated on Linux; native Windows spawn is outside this evidence.
• Unchanged host fix(mcpl): a server that fails a tools re-list keeps its known tools #183 unit + real paired tests rerun against AF 96940cd: 9/9. Its earlier full-suite receipt remains attributed to initial linked AF above.
• Unique changelog fragment passes the added-file CI condition and folds exactly once in a scratch release-script check.

Follow-up 729b36e

From the review of connectome-host #183, which follows this PR's rule: a declared baseline that isn't a string (a number in a JSON config; the config type says string, but nothing types env values when they're loaded) failed the connect with "value.trim is not a function", where Node's spawn writes any defined env value as its string form. 729b36e reads a defined value as String(value), so the declared value is the one the child sees, and reads a null as unset, like a blank: written in JSON it means no value, and read as spawn's "null" it would replace the protective default with a list that suppresses nothing.

• Test: a server whose env declares the baseline as the number 7 connects, and its child sees "7"; one that declares null gets the derived default. Without the change, the first fails the connect with "value.trim is not a function"; with null read as "null", the second sees "null".
• The three baseline files (placed-reaction-baseline, reaction-baseline-platform, refusal-reaction-baseline): 42/42.

Sweep follow-up 2c328b7 and 2ec3d57

The house runs an internal review of each change before merging. At 96940cd it raised 18 issues. 2c328b7 fixes the 13 judged worth fixing now, and 2ec3d57 is a text addition from its review.

• New tests:

  • a reconnect respawns the child with a marker retained since;
  • a restart against a corrupt ledger refuses, and the running child still answers;
  • blank '' and ' ', declared or inherited, give the literal default;
  • the replacement log line;
  • a URL-only WebSocket config reaches the registry as the same object with no env;
  • custom IDs at 16 and 21 digits stay composite, at 17 and 20 reduce to the ID, and a short composite stays;
  • inherited property names take the fallback.

  The platform tests now expect the default where the kept spelling is blank. The inherited-override check compares with the literal default.

• Red first, on the VPS (Node 24.21.0): with 96940cd's src/ merged onto main and these tests, 11 fail.

  • placed-reaction-baseline, 25 of 30: the two blank cases, the log line, the reconnect and the restart fail.
  • reaction-baseline-platform, 2 of 7: its five blank-as-unset expectations fail.
  • refusal-reaction-baseline, 3 of 4: the inherited-name case fails.

  The other new cases pass there. They pin behaviour 96940cd already had: the WebSocket pass-through, the ID bounds and the literal default. The mutations below show each is load-bearing.

• Each piece removed (mutations of the compiled framework), each caught:

  • the default derived once, with no getter;
  • the restart's check moved after the disconnect;
  • a blank value kept;
  • no log line;
  • the plain lookup;
  • the ID bounds widened to 16 or 21 digits, or narrowed to 18;
  • a WebSocket config given the env.

• Full suite on the VPS, 2c328b7 merged onto main 02adf27, node --test --test-force-exit per file. 2ec3d57 changes only the README and the fragment.

  • Node 20.20.2: 1415/1415 across 128 files. Main alone: 1377/1377 across 126. The difference is the two new files (30 and 7) and the inherited-name case.
  • Node 24.21.0: 1414/1414 counted. --test-force-exit cut history-module-realstore to 27 of 28, and alone and unforced it passes 28/28, as placed-reaction-baseline passes 30/30.

Companion and merge order

#262 conflicts with this head in src/framework.ts: two hunks in the imports, the connect around addServer (in connectMcplServerInternal here, and in the connectHeldMcplServer that #262 splits out of it), and restartMcplServer's checks. Whichever lands second keeps both sides: #262's try/catch around addServer, its admission and in-flight checks, and this PR's connectionConfig passed to addServer. This PR's ledger read goes only where an awareness barrier reads the ledger, so that a corrupt Discord ledger never refuses a server that doesn't read it:

• In a connect, before registration, and only for an MCPL (legacy) family connect, since feat(mcp): modern MCP (2026-07-28) servers beside MCPL, over stdio and Streamable HTTP #262's modern-family connect returns before the barrier. Git's automatic merge places the read before registration in connectHeldMcplServer for both families, without a conflict, so it has to be moved under the family check.
• In a restart, after feat(mcp): modern MCP (2026-07-28) servers beside MCPL, over stdio and Streamable HTTP #262's admission checks and before the disconnect, and only when the config it restarts with is MCPL family.

Related to #95. The connectome-host #183 draft companion removes its refusal-only default, which would otherwise remain an explicit override. Merge and release this AF change including the Windows/custom-emote asks' resolution first; then the host companion must require that actual published version before it is ready to merge. AF alone does not change an old host's injected override.

Out of scope

• A runtime connect whose awareness barrier fails closes only its own connection, and the gate it installed keeps the other servers' data planes paused until another barrier completes. That's main's connect path. With this PR, a ledger that can't be read refuses the connect before the gate is installed; a barrier that fails for another reason, such as a ledger that reads but can't be written, still meets it.

Not verified

No live Discord or provider was exercised. Tests use real framework/Chronicle and stdio children with mocked inference. Windows cases use platform/env simulation on Linux, not a native Windows spawn. WebSocket adapters manage their environments separately. The reconnect case crashes a fixture child; a reconnect against a ledger that becomes unreadable is described from the code path (reconnectOnce catches the spawn's throw and schedules a retry), not tested. The connect and restart refusals are tested against a corrupt ledger file; a ledger that reads but can't be written passes the restart's read and then fails the barrier's write after the disconnect, which is described from the code, not tested.

When a server config has both `command` and `url`, the transport selector starts a stdio child, but this URL check skips baseline injection. Without an explicit server value, the child receives no framework-derived suppression default, so framework-placed reactions can re-enter the agent’s context.

Summary

The PR derives a reaction-suppression baseline from refusal markers, effective awareness settings, and retained outbox markers, then supplies it to MCPL children at startup and runtime.

• Explicit server and inherited environment values retain precedence.
• Stdio configs carrying both a command and URL miss the new default.

Addressed in 327080a. Injection now calls isWebSocketTransport, the same selector used by openTransport, instead of checking URL presence. Two real-child regressions cover command+URL with implicit and explicit stdio selection; an explicit-WebSocket control retains its environment unchanged. The two stdio cases fail before the fix (17 pass / 2 fail in the combined suites).

The update also includes Wren's independently found Windows casing corrections: declared and intentionally inherited baseline choices use the same case-insensitive lookup, including Worker env copies and empty values. Those Windows cases are simulations at the real connection-construction boundary on Linux.

Final full suite: 1120 pass / 0 fail / 0 skipped, versus main 1101/0/0; build/typecheck pass. Wren re-reviewed the final head and independently passed 23/23 focused tests without force-exit. The unchanged host companion's pair was rerun against this head: 9/9. Host #183 remains draft pending the actual AF release/dependency update.

Reviewed at head 327080a, two-panel review with probes against the built branch and a compiled discord-mcpl 6f38d13. APPROVE — the design is right and the coverage gap it closes (#95) is real — with two sharp, small asks below, each verified against ground truth rather than the PR's own tests.

Verified first-hand:

• Red/green: 14/19 fail at base (clean compile), 19/0 on the branch; full suite 1116/0/4.
• The cross-repo contract is real: discord-mcpl's parseSuppressionEnvTokens reads exactly DISCORD_SUPPRESSED_REACTIONS_BASELINE, comma-tokened, file-key-authoritative — and a full round-trip of the real getPlacedReactionBaseline().join(',') through DiscordFiltersState.isSuppressed suppresses unicode (incl. FE0F variants, ZWJ, padded tokens) with no token-count desync.
• Injection coverage is total by construction (single addServer site; startup and hot-deploy both pass through it); WebSocket exclusion uses the very predicate openTransport resolves with, so classification cannot diverge from the transport actually opened.
• Restart freshness verified: mcplServerConfigs stores the caller's pre-injection config, so restartMcplServer re-derives. (Auto-reconnect reuses the injected config — frozen baseline across reconnects — but that's harmless: the awareness emoji is construction-only.)
• Precedence: declared values win including explicit empty strings; inheritEnv gates the process.env fallback. And credit where due: at base, declared-lowercase + inherited-UPPERCASE handed the child the host's value (uppercase sorts first at spawn); this PR correctly gives the declared value, matching buildChildEnv's "declared on top".
• Baseline builder is fail-closed (typed throw on unreadable ledger; no partial baseline), deduped, empty-filtered.

Ask 1 — the win32 duplicate-spelling pick doesn't match what spawn actually resolves. Ground truth from node v20.20.2 lib/child_process.js normalizeSpawnArguments (and the identical block in bun 1.3.14 src/js/node/child_process.ts): on win32, duplicates are deduped keeping the FIRST key in lexicographic sort order per toUpperCase, not the last-inserted. So .at(-1) picks a value spawn may not deliver: probed with the built composition plus that exact dedupe — {UPPER:'first', lower:''} gives the child 'first' at base but the PR injects from ''; same inversion for Worker-copy parents. Your platform tests encode the same assumption (expected = Object.values(env).at(-1)), so they pass while disagreeing with spawn. Fix is one line — Object.keys(env).sort().find(k => k.toUpperCase() === KEY) — plus flipping the tests' expectation. Rare in practice (two spellings in one object), which is why this is an ask and not a blocker.

Ask 2 — custom-emote awareness markers don't suppress in their full forms. A configured marker like <:mark:ID> (or mark:ID, <a:mark:ID>) survives the join/parse round-trip as a composite token, but events arrive as name+id and normalize to mark; the idSet only admits pure 17–20-digit tokens. So "includes the configured awareness marker" currently holds only for unicode or bare-name customs. No deployment we can see configures a custom marker (all ride the unicode default), so: ask, not blocker — but if any deployment ever sets one, this silently reopens the exact gap #95 describes. Fix: map /^<?a?:?(\w+):(\d{17,20})>?$/ to the bare id in getPlacedReactionBaseline, with a test. (A comma inside a configured value splits into an extra token — invalid input, noting only.)

CHANGELOG.md direct edit — same changelog.d/ fragment ask as the sibling PRs.

(Probe credit: the spawn-source ground truth and the discord-mcpl round-trip matrix are the second reader's work on our side; deployment-config check and code-path verification mine.)

Thank you for the source-backed review. Both asks are addressed in 96940cd, with current main df97a85 merged while retaining the reviewed history.

1. Windows baseline lookup now resolves the first lexicographic spelling within each source, then layers declared over inherited values. I verified Node24's actual normalizeSpawnArguments; our previous last-insertion expectation was incorrect. Felix aligned fix(mcpl): preserve child CA bundle and proxy settings #205 separately at 038e06b. Their clean composition passes 39 focused tests and nine injection-to-child-env probes, including conflicting spellings in both insertion orders and empty overrides. Windows evidence is simulated on Linux.
2. Recognized composite custom markers become bare snowflake IDs before snapshot deduplication. Stored markers, add/remove payloads, Unicode/name tokens and explicit operator env stay unchanged. The real DiscordFiltersState pinned at 6f38d13 failed all three initial custom-form round trips before and passes after; same-ID renames suppress while same-name/different-ID events remain distinct. Wren's independent review additionally passed four forms and the 38-test focused set.

The changelog entry now lives in changelog.d/211-placed-reaction-baseline.fixed.md. Host #183's unchanged real-child pair passes 9/9 with this candidate, and its readiness gate explicitly requires a published AF version including these asks' resolution.

Final full compiled suite at 96940cd: 1149 pass / 0 fail / 0 cancelled / 0 skipped, using Node24 with concurrency2, a 60s per-test timeout and force-exit. Build/typecheck pass. The PR body separates these final receipts from the prior reviewed heads and your public firsthand approval.

@slimepriestess Two more commits sit on top of 96940cd, which answered your two asks: 2c328b7 and 2ec3d57, a fast-forward. They answer the house's automated review of 96940cd, which runs across each change before merging. Would you re-read them? The description is updated.

What changed in behaviour:

• The default is derived at each spawn of a stdio child, not once at the first connect. The child's env is a getter that the transport reads at every spawn, so a child respawned by an automatic reconnect gets the markers retained since.
• A blank value (empty or whitespace), declared or inherited, now counts as unset, and the default is derived. discord-mcpl reads an empty value as "no tokens", so a blank inherited variable turned the protective default off. This reverses the earlier "including empty strings". A non-blank operator value still wins, and the framework now logs that it replaces the default.
• A runtime restart checks the ledger before it stops the running child, and refuses without stopping it when the ledger can't be read. A reconnect that can't read it fails and retries rather than spawn the child without the default.
• A refusal category named like an inherited property (constructor, toString) now gets the 🛑 fallback.

Checks: with 2c328b7 merged onto main 02adf27, the suite passes 1415/1415 on Node 20.20.2 (main is 1377). On Node 24.21.0 it passes 1414 counted, plus 28/28 for a file --test-force-exit cut short, rerun on its own. Eleven of the new cases fail with 96940cd's src/.

@slimepriestess Pushed 2ec3d57..729b36e, one commit: a declared baseline that isn't a string no longer fails the connect. Please read it with the sweep round, 2c328b7..729b36e, when you re-read. A number in a JSON config used to fail the connect with "value.trim is not a function". It's now read as its string form, as spawn writes it to the child, and a null counts as unset, like a blank. The fragment and the description say so, and the test covers both cases.

[slimepriestess]

Re-read at 729b36e. Approve.

Scope: everything after the main merge 56b73ea. That's 96940cd (the answer to our two asks at 327080a, which we hadn't re-read), the sweep round 2c328b7 and 2ec3d57, and 729b36e. A note on the range you gave, 2c328b7..729b36e: in git that leaves out 2c328b7 itself, which is the round's behaviour change, so I read from the merge instead.

Checks, at 729b36e on Node 20.20.2 with the repo's own harness (npm run build, then npm test, which runs pretest's fixture copy): 1156 pass, 4 skipped, 0 fail. This head isn't merged with current main, so the count is lower than your 1415. The three baseline files are 42/42.

The getter, traced to the spawn. The default being derived at each spawn depends on nothing copying the config between connectMcplServer and spawn. Nothing does. The registry passes the object through. connect and the reconnect stub both keep it as-is (connection.config = config, stub.config = config). attemptReconnect hands this.config to handshake, and StdioTransport reads config.env through buildChildEnv at the moment it spawns. The same path carries the refusal: a getter that throws on an unreadable ledger throws inside attemptReconnect's try, so the reconnect fails, emits reconnect-failed and is rescheduled. Nothing spawns without the default. The framework's stored config stays the caller's unwrapped one, so restartMcplServer derives afresh, as the comment says.

Windows, checked against spawn's rule. Your getter always writes the canonical all-uppercase key. Uppercase letters sort before lowercase, and _ is the same in every spelling, so the all-uppercase spelling sorts first among all case variants. Node dedups before libuv ever sees the block: on win32, normalizeSpawnArguments sorts the env keys and keeps the first of each case-insensitive name (lib/child_process.js, v20.x lines 681–694, v24.x lines 732–745). That's the same default sort declaredReactionBaseline uses, so the child sees exactly the value it resolved. That holds when the declared and inherited sources spell the name differently, and when a blank spelling and a non-blank one sit in the same source.

Each behaviour claim fails its own test when broken. I mutated src, rebuilt and ran the three files:

Mutation	Result
env frozen as a value at connect	1 red: a reconnect respawns the child with a default derived at that spawn
restart's ledger pre-check removed	1 red: a restart that needs the default refuses on a corrupt ledger and leaves the child up
null not treated as unset	1 red: reads a non-string declared baseline as the child sees it…, and a null as unset
blank not treated as unset	7 red, including both blank cases and the Windows declared-case-variant case

All four were restored, and the files are back to 42/42.

The Object.hasOwn guard on refusal categories and the suppression-token mapping (a custom emoji becomes its bare ID; stored markers and add/remove payloads unchanged) read correctly. The README section, the changelog fragment and the source comments match the code, including the disclosed side effect that members' own 💤 and awareness-emoji reactions stop reaching the agent too.

Replying to this review.

Thank you for the re-read, and for tracing the getter through to the spawn and checking the Windows sort against Node's own dedup. You're right about the range: 2c328b7..729b36e leaves out 2c328b7 itself, which is the round's behaviour change, so reading from the merge was the right call. From now on I'll give ranges that start from the last commit you read.

@slimepriestess We pushed 729b36e..8ef10bc, which merges main in and adds three rounds from our internal review. Would you re-read it before we merge? You last read 729b36e, so everything after it is new:

• 97a8483 merges main c2f9bae. Its one conflict was an import line in src/framework.ts, and it keeps both imports. git show --remerge-diff 97a8483 shows the resolution.
• ffb39ee and 8ef10bc count a baseline value with no tokens, as discord-mcpl's parser reads them, as unset. That now covers commas alone, :, :: and a lone U+FE0F, which ${A},${B} or :${NAME}: give when the variables are empty. The framework applies the parser's own steps, from parseSuppressionEnvTokens and normalizeReactionEmoji in discord-mcpl's src/filters.ts.
• ffb39ee and deb888c read the awareness ledger before every restart stops its child, and before every connect registers anything. On a corrupt ledger, a restart of a server with its own baseline used to stop the child and then fail, and a connect of a reconnecting server left a closed stub registered.
• adff8a2 corrects the README and the changelog for startup: a startup connect, whose routing is staged beforehand, refuses before it spawns.

The rounds alone are git diff 97a8483 8ef10bc. The description's Tests section has this push's receipts, and its "Companion and merge order" section says how this PR and #262 combine.

@slimepriestess We'll merge this once our pre-merge checks pass on its merge with the then-current main, and not before 20:00 UTC today. If you'd like to finish your re-read first, say so here and we'll wait.

It merges cleanly with main at 3f917005, and CI is running at 8ef10bc.
