Subject: [PATCH 01/42] feat: publishing registry media seam
 (loadAsset/openAsset) + SPENC1 decrypt + multipart transport

The Mastodon connector's uploadAll resolves asset ids via loadAsset/openAsset.
The registry wires these hooks from a mediaResolver that the scheduler injects:
media_assets lookup (workspace-scoped via SET LOCAL) + R2 download + SPENC1
decrypt (extracted from the api's storage into connector-runtime/media.ts).
provider-fetch gains serializeBody for multipart media uploads through the
pinned transport channel.

Subject: [PATCH 02/42] fix: wire scheduler media resolver into publishing
 registry

The registry accepted media hooks but nothing supplied them, so Mastodon
media posts failed uploadAll (INVALID_POST attempts). PublishingMediaResolver
in the scheduler resolves workspace-scoped media_assets rows via RLS tenant
context and reads plaintext bytes from S3 with SPENC1 open (S3_KEK), matching
the api's S3Storage frame format.

 connection

uploadAll/uploadAsset call the media hooks with (connection, assetId) so
implementations can resolve the workspace; the registry adapter threads
connection.workspaceId into the resolver.

Media posts are two mutations (media upload + status create). The dispatch

MASTODON_PUBLISH_DEDUPE_ORIGINS, so without it every media post died as

The Files tab dropzone still enforced the old 20 MiB cap client- and

stale '100 MiB' message on the video upload rejection.

Audio-less inputs no longer emit [0:a] maps that ffmpeg rejects; the worker
branches to an anullsrc bed configured at the output preset's rate/layout.

Subject: [PATCH 07/42] feat: Files payloads move from oCIS WebDAV to R2 object
 storage
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Files tab was the only payload path not on object storage, violating the
2026-10-06 directive (object storage is the ONLY media I/O path) — and oCIS's
WebDAV surface is currently 500ing server-side, which made every upload fail.

Uploads now seal + dedupe into R2 via StorageService (SPENC1, content-
addressed); downloads read R2 when storage_key is set, falling back to oCIS
for legacy rows. Share-into-library copies oCIS Drive sources into R2 and
records the real sha256 instead of a placeholder. Migration 041 adds
chat_media_archive.storage_key.

Subject: [PATCH 08/42] feat: chunked video ingest API (init / chunk /
 complete)

Cloudflare's proxy plan rejects bodies above ~100 MB, so whole-body video
uploads cannot exceed it no matter the origin limits. Clients now slice into
10 MB chunks: POST /video/upload/init, PUT /video/upload/:id/chunk/:index,
POST /video/upload/:id/complete reassembles to disk, seals, stores to R2 and
runs the normal probe + job pipeline. Max chunked upload: 100 GiB. Tests 17/17.

+ * Chunked (resumable-style) large-file ingest.
+ *
+ * Cloudflare's free plan rejects proxied request bodies above 100 MB, so a 20 GB
+ * camera original can never arrive in one POST /video/upload. The client instead
+ * slices the file into CHUNK_SIZE_BYTES (10 MiB) chunks — each far under the
+ * limit — and PUTs them one at a time. Each chunk is written at its fixed offset
+ * (`index × 10 MiB`) into a sparse temp file, so chunks may arrive in ANY order
+ * and may be retransmitted after a network failure without corrupting the file.
+ *
+ * On complete, the assembled file goes through the SAME SPENC1 seal → S3
+ * putContent path as every other upload.
+ *
+ * ── MEMORY REQUIREMENT (read this) ────────────────────────────────────────────
+ * The seal function (apps/api/src/storage/storage.ts) takes a whole Buffer, and
+ * S3 PutObject is likewise handed one body. Assembling therefore peaks at
+ * roughly 2× file size of RAM: one Buffer of plaintext for the seal plus the
+ * sealed copy the S3 client transmits (plus ~1× transiently for
+ * Buffer.concat in seal). There is no way to bound that without streaming
+ * encryption + multipart S3, which would change the storage contract for every
+ * other caller — out of scope here.
+ *
+ * Practical sizing: a 20 GB upload needs a host with ≥ 48 GB RAM
+ * (MAX_OLD_SPACE_SIZE raised, or --max_old-space-size=32768+, plus headroom for
+ * the sealed copy). Up to ~2 GiB the ordinary multipart path is fine and cheaper.
+ * Disk also matters: /tmp must hold the assembled file (see SP_CHUNK_UPLOAD_DIR,
+ * default /tmp/uploads) on top of whatever S3 buffers.

Files payloads moved to R2 in 041; this removes the remaining oCIS coupling:
- delete the oCIS WebDAV client; verifyWhileStreaming moves to its own
  storage-agnostic module (verify-stream.ts)
- group-files: storage_key is the only payload source; legacy rows answer
  'retired storage' instead of touching oCIS
- collective share: the ocis-resource item kind is gone (peertube links stay);
  share-into-library was R2-backed since the previous commit
- import-drive endpoint removed (no web caller); import-chat (homeserver) stays
- web: Drive tab + embedded oCIS page removed; Library is the Files view
Legacy e2e rows (2) deleted; every remaining archive row is R2-backed.

-/**
- * oCIS WebDAV port — the ONLY payload I/O path for group files.
- *
- * The API streams bytes through itself on both upload and download: it NEVER
- * mints or persists a presigned object URL (docs/occupymedia-storage.md
- * "Persist library links/share IDs and expiry, not presigned object URLs").
- * Downloads re-verify the SHA-256 while streaming so storage-level tampering
- * is detected instead of silently relayed.
- *
- * Server-side COPY ("share into a collective's library") moves no bytes
- * through the API at all: oCIS performs the copy in the storage backend and
- * the API only learns the resulting file id / etag / length, which is exactly
- * the metadata the group files index stores. The copy is verified by oCIS
- * itself; the index records what the server committed, never a claimed length.
- *
- * ENV CONTRACT (lazy getters — read per call so tests/parallel deployments
- * can reconfigure without a rebuild; nothing is read at import time):
- *
- *   FILES_OCID_WEBDAV_URL   oCIS WebDAV root, e.g. https://files.example.org
- *   FILES_OCID_USER         service account username (the scoped oCIS identity)
- *   FILES_OCID_PASSWORD     service account password
- *   FILES_PUBLIC_BASE       public base of the file library, used to build the
- *                           persistent (authenticated) library link returned in
- *                           GroupFile.shareLink.url — a stable resource URL,
- *                           NEVER a presigned object URL.
- *
- * The oCIS deployment lands in parallel; when the env is unset the port
- * reports unconfigured and routes fail 503 rather than silently no-op.
- *
- * WebDAV shape: PUT returns the stable resource id (oc-fileid) and ETag
- * (oc-etag / etag) this index needs; plain PUT/GET carry the bytes. The
- * transport is injectable (OCIS_FETCH token) so tests stub it without HTTP.

Intake stores alt texts positionally (aligned with mediaAssetIds) but the
Mastodon upload reads an asset-id-keyed providerMetadata.altText map, so
descriptions were silently dropped. postOf translates the array into the map.

+- The scheduler resolves media at dispatch (**PublishingMediaResolver**: RLS workspace lookup + R2 download + SPENC1 open).
+- `MASTODON_PUBLISH_DEDUPE_ORIGINS=https://social.occupymedia.cc` **must stay set**. Media posts are two provider mutations (media upload + status create) and the dispatch gate refuses the second without a verified dedupe origin.
+
+### 10.4 Produce worker
+- Runs as a **separate container** (`produce-worker`) and needs **ffmpeg + a font** — `DejaVuSans-Bold` at `/usr/share/fonts/truetype/dejavu/`.
+- `MEDIA_DEBUG_STDERR=1` routes ffmpeg stderr to `/tmp/ffmpeg-debug.log` for debugging.
+
+### 10.5 Known ops note
+- Restarting the api container repeatedly can trip the homeserver login rate limit (`M_LIMIT_EXCEEDED`) and crash bootstrap — wait **~2–3 min** between api restarts.

+## 11. Upgrading
 
 1. Back up DB + confirm KEK backups (§4.3).
 2. `git pull && pnpm install`.

+### 10.1 Media attachments for publishing
+- `POST /media` (multipart `file`); content type is **magic-byte sniffed** (jpeg/png/webp/mp4/webm) — the extension is never trusted.
+- Caps: image **10 MiB**, video **64 MiB**, and at most **4 attachments per post** (`MAX_MEDIA_PER_POST`).
+- Read back via `GET /media/:id` (auth-scoped). Bytes live in R2 object storage — SPENC1 envelope-encrypted, content-addressed `sha256` keys (§3.8 scheme).
+
+### 10.2 Alt texts
+- Drafts carry `altTexts` positionally aligned with `mediaAssetIds` (0–4 entries; `null` = no alt text for that slot).
+- At publish, the scheduler maps them into `providerMetadata.altText` (asset-id keyed); Mastodon media uploads receive them as descriptions.
+
+### 10.3 Video producer
+- `POST /video/:id/produce` accepts `{ overlays?, voiceover?, outputLabel?, lane? }` — closed enums with a strict key allowlist; unknown keys are rejected. Overlay kinds: `lower_third | logo | clock`; overlay text runs through the filtergraph-metacharacter blocklist before it reaches an FFmpeg graph.
+- Jobs execute in the **produce-worker** (its own container, `MEDIA_WORKER_LANE=local`): claim/lease via polling with `SKIP LOCKED`; stale leases are re-queued.
+- The output is a **derived library asset** (`derived_from`), publishable like any other asset.
+
+### 10.4 Audio-less sources
+- The command-builder synthesizes an `anullsrc` silence bed — configured at the output preset's rate/layout — instead of emitting `[0:a]` maps that ffmpeg rejects.

+- `POST /video/upload/init` → `PUT /video/upload/:uploadId/chunk/:index` → `POST /video/upload/:uploadId/complete`.
+- 10 MiB chunks (`CHUNK_SIZE_BYTES`) sidestep Cloudflare's ~100 MB proxy body cap. The server reassembles, seals, stores to R2, then runs the normal probe pipeline.
+- Max chunked upload: **100 GiB** (`MAX_CHUNKED_UPLOAD_BYTES`).

Subject: [PATCH 13/42] feat: direct-to-R2 Files uploads (client-sealed SPENC2)
 + chunked video dropzone + multi-file queue
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

For scale: payload bytes go browser → R2 → browser; the api handles keys,
authz and metadata only, so a cheap box can serve thousands of users.

- SPENC2 frame (browser-sealed, P-256 ECDH → HKDF wrap of a per-file CEK,
  10 MiG AES-GCM segments): storage.ts gains the reader (magic-branched
  getObject), presignPut/headObject, openDirectHeader; sealForDirect is the
  reference sealer for cross-implementation tests
- Files API: GET /files/direct/config, POST /files/direct/init (presigned
  PUT), POST /files/direct/complete (HEAD-gated commit), POST
  /files/:id/direct-download (presigned GET + CEK ticket)
- web: lib/direct-storage (WebCrypto seal/open), lib/files-direct (flows),
  dropzone rewritten with a multi-file sequential queue (per-file status,
  direct-first with server fallback), file download decrypts in-browser for
  direct objects (falls back to streaming)
- video dropzone wired to the chunked ingest API (>10 MiB → init/chunk/
  complete), fixing the Cloudflare ~100 MB body cap for large videos
- DIRECT_EC_PRIVATE_KEY (P-256, PKCS8 b64) wired through compose; cross-impl
  roundtrip tests prove web-seal ↔ server-open byte compatibility

Subject: [PATCH 14/42] fix: direct-download reads the sealed object for its
 CEK header

getObject decrypts by magic, so feeding its plaintext into openDirectHeader
always failed. getSealedObject exposes raw bytes for the header read;
DirectStorageMembers and the test fakes carry the new member.

POST /video/direct/init|complete: the browser seals (SPENC2) and PUTs
straight to object storage; the api HEAD-checks, registers the unprobed
asset and queues a probe job — video bytes never cross the api box.

Worker side: produce_job_claim widened to probe jobs (042), the runner
gains a probe lane (sealed fetch → SPENC1/SPENC2 open by magic → scratch →
ffprobe → metadata write-back → complete 100), worker storage reads SPENC2
frames via DIRECT_EC_PRIVATE_KEY (inherited through compose appenv), and a
ported ffprobe util. Probe rows carrying input_json fail instead of
stranding; the claim guard no longer strands probe rows as invalid.

downloadSealed fetched raw bytes (getSealedObject) and handed ciphertext to
ffprobe — every direct upload failed 'Invalid data found'. The lane now uses
getObject, whose magic branch opens SPENC1 and SPENC2 alike.

Per the adopted qwen38 plan §2 (+ glm53 amendments): video_processing_jobs
kind 'assemble' (claim widened via 044), EdlPlan mirror validation
(lenient-fail), the filter_complex builder (interleaved concat pairs, fit
cover/contain chains, absolute-timeline PNG overlays with enable windows,
VO adelay/sidechain duck, hard-breaking word wrap for card PNGs), and the
runner's assemble path with pre-spawn trim gates, attempt backoff and 15-min
cap. Sources open by magic (SPENC1 kek / SPENC2 direct key) so direct-to-R2
uploads assemble without the api ever seeing bytes. Tests: builder 18,
edl-plan 12, overlay-png 3, runner fakes extended.

+-- 044: the produce worker claims ASSEMBLE jobs (editor-v2 L1, the worker assemble lane).
+--
+-- An assemble row is an editor-v2 timeline render: input_json carries
+-- { edlProjectId, project: EdlProject } (the EDL shapes live in
+-- apps/api/src/media-control/edl.ts), video_asset_id points at the project's
+-- first source clip, and the produced output is a derived video_assets row
+-- exactly like a compose/mix produce. 043 owns the intake half of the feature
+-- (edl_projects + widening video_processing_jobs.kind's CHECK to admit
+-- 'assemble'); THIS migration is only the worker's half — the claim's kind
+-- filter widened so the lane can pick those rows up.
+--
+-- Same body as 042 with 'assemble' added to the kind list; 'transcoding'
+-- remains the lease state and the stale-lease sweep is unchanged, so a worker
+-- that dies mid-assembly still hands its row back through the same path a
+-- dead compose/mix encode does today.

+/**
+ * Assemble command builder (editor-v2 L1; adopted plan §2 graph, BINDING).
+ *
+ * Typed plan in, argv out — the same discipline as produce/command-builder.ts:
+ * nothing here takes a free-form filter string, and NO operator text ever
+ * reaches a filter. That is the plan's injection stance made concrete:
+ *
+ *   clips    → the asset's scratch path (named by content hash) + numeric -ss/-t
+ *   cards    → a PNG whose pixels are the api-side renderer's (rasterized off the
+ *              filtergraph entirely — "no drawtext at all" per the verdict)
+ *   overlays → PNGs too: an EdlOverlay names the api's overlay templates, and the
+ *              SAME mechanism the compose path uses for card/overlay pixels —
+ *              production/render.ts's overlaySvg → sharp worker → PNG — produces
+ *              them (see overlay-png.ts); ffmpeg only ever composites the PNG
+ *   text     → never a filter argument anywhere in this module
+ *
+ * Graph (one process, one filter_complex, one encode):
+ *   per clip i   [i:v] transpose → scale/crop-or-pad (fit) → setsar=1 → fps=30 → format [vK]
+ *                [i:a] aformat… , volume=dB [aK]
+ *   per card k   (-loop 1 -t dur PNG) [c:v] fps=30,format [vK]  +  anullsrc → [aK]
+ *   concat n=N:v=1:a=1 → [vcat][acat]
+ *   per overlay  [vcat][oJ] overlay=enable='between(t,s,e)' [vJ]   (absolute timeline ms)
+ *   voiceover    adelay=offsetMs → volume=gain; duckOriginal → sidechaincompress
+ *                keyed by the VO (the produce path's duck chain), else amix duration=first

+ * EdlProject — the editor-v2 timeline contract, LENIENTLY validated worker-side.
+ *
+ * mirror of apps/api/src/media-control/edl.ts — keep in sync (mirror-assert lives in the api)
+ *
+ * The api module owns the strict validator crews post against (closed enums,
+ * basis-point geometry, GAIN_DB_STEP multiples, <=50 items, <=15 min total) and a
+ * mirror-assert test that fails when the two files drift. This copy exists so the
+ * worker package never imports the api module graph (the filemap's boundary rule,
+ * same standing as ./ffprobe.ts being a verbatim port of the api's ffprobe).
+ *
+ * Why LENIENT here: input_json is a queued row. The api already rejected every
+ * bad shape before enqueueing; the worker only needs to (a) trust nothing it
+ * would feed to a shell — nothing here ever is, argv only — and (b) fail the JOB,
+ * not the process, when a row is not the shape this build understands (an
+ * upgraded api ahead of the worker, a tampered row, an unknown `version`). So
+ * this parser checks structure + bounds, ignores nothing silently, and throws a
+ * single error type with a field path — the runner maps that to a failed row.
+ *
+ * v1 is closed (the plan's anti-NLE-creep rule): version !== 1 is an unknown
+ * shape, and the mirroring api test is what enforces field-for-field sync.

+ * THE MECHANISM IS THE API'S, VERBATIM IN SHAPE: apps/api/src/production/render.ts
+ * (overlaySvg → an isolated sharp worker thread → PNG). That is exactly how
+ * compose-path overlay pixels are produced today: production.service.ts renders
+ * an overlay through `renderOverlay`, seals the PNG into object storage, and
+ * ffmpeg only ever sees the sha-named asset (`overlay_revisions.asset_id`).
+ *
+ * The worker needs the same pixels OFFLINE (it has no api to call, and the plan
+ * forbids drawtext for user text outright), so it runs the renderer's exact SVG
+ * templates in its own isolated sharp worker — same template markup, same
+ * geometry, same escape function, same resource limits — and writes the PNG to
+ * the job's scratch dir under a content-hash name.
+ *
+ * sharp itself is resolved like the api resolves it (SHARP_MODULE_PATH, else the
+ * ambient install): the worker image carries the same binary the api does, and a
+ * box without it fails the JOB as `render unavailable` — never a fallback to
+ * drawtext, because a crew must never ship text that was not renderer-rasterized.

apps/api/src/media-control/edl.ts: the EdlProject schema (closed enums,
integer ms, 3dB steps, <=50 items, <=15 min, filtergraph-metacharacter
blocklist on card text) + validateEdlProject — the mirror-assert owner for

POST /video/edl, PATCH autosave, GET (project + latest assemble job),
POST :id/render (queues kind 'assemble' with the validated project).

Subject: [PATCH 21/42] fix: install sharp in the media-worker for card/overlay
 PNG rasterization

The assemble lane's card pass resolves sharp (SHARP_MODULE_PATH or
require.resolve) like the api does; the worker image never had it, so every
assemble job failed 'sharp not found'.

Direct-object sources download as <sha>.bin (scratchAssetName's fallback for
non-sha256 keys); the allowlist rejected them before spawn.

Card and audio-less-clip anullsrc sources are infinite; concat never
terminates an infinite segment, so the encode hung forever at 30%. atrim
pins each bed to its item's span (card duration / clip trim).

+# Editor v2 RFP — FINAL judgment (3 of 4; deepseek a no-show)
+
+deepseek: 5 launch attempts, all died to infra (latest: lease expired at seq 17, no output). Excluded.
+In hand: nemotron (19/25 preliminary), glm53 (24/25 preliminary), qwen38 (scored below).
+
+## qwen38 (qwen3.8-27b) — assessment
+
+Strengths:
+- Landscape-native schema from v1 (`aspect: '16:9' 720p | '9:16' 1080×1920`, `fit: cover|contain`) —
+  satisfies the mandatory amendment glm53 needed, natively.
+- Captions are schema-first: Speaches faster-whisper large-v3-turbo (correct model per research),
+  words JSON as source of truth, SRT/VTT/ASS derived, ASS burn-in re-timed through the EDL.
+- Container generalization is disciplined: the in-flight produce payload becomes a degenerate
+  EdlProject → ONE validator, ONE render path; version discriminator + version-bump policy as the
+  explicit anti-NLE-creep defense.
+- Job model reuses the in-flight producer lease pattern (`kind='assemble'`, SKIP LOCKED).
+- Render: one process / one filter_complex / one encode, measured 1.2× RT; stream-copy honestly
+  rejected inside assemblies; cards as loop-PNG from the existing overlay renderer — no drawtext
+  at all; pre-spawn trim validation against probe durationMs; retry/timeout/scratch-cleanup policy.
+- AI: Speaches + SigLIP + job runner on gpu-01 over Tailscale, worker stays pure FFmpeg; VRAM budget
+  table; license register incl. BLOCKED list (XTTS-v2 CPML, F5-TTS CC-BY-NC, RVM GPL-3, Ultralytics AGPL-3);
+  auto-editor as SUGGESTED cuts with human confirm.
+- UI: only new files, primitives named as reused, mobile single-column with chevron reorder, ≥44 px
+  targets, one-thumb flow, 8 documented shortcuts, exact brand tokens.
+- Risk honesty: 5 risks with mitigations; "preview ≈ final"; measured-vs-EST labeling.
+
+Weaknesses: stale migration number (036 vs actual next); no explicit schema-drift guard; no
+render-CPU-contention semaphore; thinner canvas/revision formalism than glm53.
+
+## Final scoring (1–5 per criterion)
+
+| Criterion | nemotron | glm53 | qwen38 |
+|---|---|---|---|
+| Correctness vs real constraints | 3.5 | 4.5 | 4.5 |
+| Concreteness (files/jobs/models) | 4 | 5 | 5 |
+| Speed-to-value for crews | 4 | 4.5 | 4.5 |
+| Look-and-feel respect | 4 | 5 | 5 |
+| Risk honesty | 3.5 | 5 | 5 |
+| **Total** | **19/25** | **24/25** | **24/25** |
+
+## Verdict
+
+glm53 and qwen38 tie at 24/25. Tie-break on the deltas: glm53's only mandatory amendment was a SCHEMA
+change (portrait-only canvas); qwen38's gaps are ADDITIVE process guards. 
+
+**Decision: adopt qwen38 as the editor-v2 plan base, with two glm53 amendments folded in:**
+1. glm53's mirror-file + mirror-assert convention for the EDL schema (API↔worker drift guard).
+2. glm53's render semaphore (≤2 concurrent niced renders) so batch renders never starve the live compositor.
+
+nemotron: not adopted (wrong transcription stack, captions missing, matting confusion).
+deepseek: no-show; may be re-run later for a second opinion but is not blocking.
+
+## Implementation status
+- S1 EDL schema + /video/edl API + 043 store: SHIPPED (media-control/edl.ts, EdlController, 043)
+- L1 assemble lane: SHIPPED (044 claim widening, runner probe+assemble lanes, assemble-builder,
+  overlay-png cards, ffprobe port) — e2e verified (2 clips + card + overlay → derived asset)
+- M1 editor UI: queued
+- M2 transcription lane: sidecar deployed (Speaches-compatible faster-whisper on moxexleyhp1-1 GPU,
+  http://100.70.240.7:9000) — hub wiring pending
+- v1.5 search (SigLIP): sidecar deferred — TEI 1.8 cannot parse google SigLIP configs; needs a newer
+  TEI or the planned FastAPI wrapper

+# UX Audit — app.occupymedia.cc (live, read-only) — October 2026
+
+**Auditor:** fresh account `uxaudit-2653`, registered via `/onboarding` (solo path).
+**Method:** Playwright 1.63 / Chromium, Desktop 1440×900 and Mobile 390×844 (iPhone UA, 3× DPR).
+**Scope:** landing, onboarding, sidebar + mobile nav, streams, compose, calendar, video, groups, settings, audit, chat embed, files embed, inbox/approvals/analytics/connections/team/archive/control-room/search/more.
+**Brand check:** dark brand consistent across every screen (#060403/#0F0A09/#FF1610 trio honored); no off-brand colors observed.
+
+## Findings
+
+| # | Sev | Screen / element | Finding |
+|---|-----|------------------|---------|
+| 1 | **P0** | Compose → Publish | Button disabled with no visible reason (zero channels default): helper line far above only. No tooltip/inline reason. |
+| 2 | **P0** | First-run home (/streams) | Language Spanish-only with no toggle (t() hard-codes .es in no-collectives-home.tsx) while the landing has a working EN/ES toggle. Fails the 5-second first-run test for EN users. |
+| 3 | P1 | Sidebar | 16 ungrouped nav items, no sectioning; home route labeled "Streams"; dead "Onboarding" item when signed in. |
+| 4 | P1 | /groups | Orphaned route — linked from nowhere; background 404 /groups on load (caught). |
+| 5 | P1 | Settings | Nearly empty dead-end for solo accounts: read-only identity block + raw dump of ~40 permission strings. |
+| 6 | P1 | More menu | "Security & sessions" duplicates "Settings" (same destination); "Invite member"/"Roles" both → /team; no Groups link. |
+| 7 | P1 | Terminology drift | Channels vs Connections; Video vs Video library vs PeerTube; Audit vs Audit trail vs Audit log; Streams vs Home; Files vs Library vs Drive. |
+| 8 | P1 | Compose post-submit | Publish vs Post label drift; "0 accounts" helper reinforces nothing happens; no destination confirmation after publish. |
+| 9 | P2 | Icons | Nav icons reused across unrelated items (video icon for Streams/Control Room/Video; files icon for Files+Archive; home icon for Onboarding). |
+| 10 | P2 | Onboarding | username `pattern="[a-z0-9][a-z0-9_.-]{1,31}"` invalid regex → console error, native validation silently disabled. |
+| 11 | P2 | Chat embed | Desktop Element embed fine (harmless config 404); mobile hand-off is good. |
+| 12 | P2 | Files embed | Solo empty state good; background 400 /files?groupId=sample-group (caught). NOTE: Drive tab has since been REMOVED (oCIS retired) — stale. |
+| 13 | P2 | Loading/error states | Strong: branded spinner, OfflineBadge, per-screen empty states with next-step + CTA. Highlight. |
+| 14 | P2 | Mobile touch targets | Good: 44px enforced; Post 44×44, FAB 64×64; bottom nav + FAB thumb-friendly. |
+| 15 | P2 | Empty states | Consistent + useful across screens; only Settings (Finding 5) is a dead end. |
+
+## Status note (2026-10-16)
+Findings 1–8 + 10 queued for fixes (ux-fix agent); Finding 12's Drive tab is already resolved
+(oCIS retired, Library replaces it). Sidebar grouping (3) and terminology unification (7) land
+with the same pass.

P0-1 compose: inline 'Connect a channel to publish' beside the disabled
Publish (desktop) and above the mobile bar — the silent-disabled state is gone.
P0-2 first-run home reads the landing's tmbh.manual.lang preference instead
of hard-coding Spanish.
P1-3 sidebar: 16 flat items → 5 labeled sections (Publish/Content/Operations/
Admin); dead Onboarding item removed; Groups surfaces in Operations.
P1-4 More menu: Groups row added; Onboarding row removed.
P1-6 duplicate Security & sessions row removed.
P1-7 mobile Post → Publish (label drift); More menu labels unified
(Video library / Files / Connections / Audit trail).
P2-10 username pattern regex fixed ([a-z0-9._-] with the dash last).

SOTA lightbox patterns adapted to the hub: images zoom (wheel/double-click)
pan rotate with a filmstrip + counter + focus trap; videos play in a
brand-skinned player (scrubber with buffered range, volume, speed, PiP,
fullscreen, keyboard: space/k, arrows ±5s, j/l ±10s, m, f, p, up/down).
Payloads are E2E-encrypted, so thumbnails and playback decrypt client-side
through the session cache (direct objects via presigned GET + CEK; others
via the streaming route) — the grid shows real video stills captured in the
browser. List view stays for documents; Media/Grid is the default for
image/video items. FileRow gains a View action for media rows.

- MediaViewer branches by type: pdf (native iframe), text/json (viewer +
  copy), html (sandboxed allow-scripts run + source toggle), image (zoom/
  pan/rotate lightbox + Edit), video (brand player + Trim)
- ImageEditor: canvas crop (drag + aspect presets), rotate 90s, flip H/V,
  brightness/contrast/saturation; Save as copy uploads a NEW library file
  via the direct path (server fallback)
- VideoTrim: in/out over the duration; Cut in Video Studio registers the
  same R2 object as a video_asset, creates a one-clip EDL at the trim, and
  queues the assemble render — the cut lands in the Video library, the
  original file is never modified
- invalid type syntax fixed across the new components (prop callbacks use
  arrow types)

 ### 10.5 Known ops note
 - Restarting the api container repeatedly can trip the homeserver login rate limit (`M_LIMIT_EXCEEDED`) and crash bootstrap — wait **~2–3 min** between api restarts.
+- **DIRECT_EC_PRIVATE_KEY** (P-256 PKCS8 base64) is required by the api, media-worker and produce-worker (compose appenv) — it unwraps client-sealed SPENC2 frames. Rotation needs a re-seal migration (not yet designed).
+- The AI transcription sidecar (faster-whisper large-v3-turbo, OpenAI-compatible) runs on the moxexleyhp1-1 WSL GPU at `http://100.70.240.7:9000` (systemd unit `tmbh-transcribe`); cuBLAS/cuDNN come from pip wheels (`nvidia-cublas-cu12`, `nvidia-cudnn-cu12`) + `/usr/lib/wsl/lib`.
+- LLM serving for agent workflows: LiteLLM at `http://100.96.13.16:4000` (opencode3), key `sk-hub1-…` (hub1 virtual key), serving `qwen3.8-27b`.

+- `GET /video/direct/config` → `POST /video/direct/init` (presigned PUT) → `POST /video/direct/complete` (HEAD-gated register + queued probe job). The browser seals SPENC2 and PUTs straight to object storage — the api box never touches video bytes.
+- The produce worker claims the probe job (042 widened `produce_job_claim`), fetches the sealed object off R2, opens by magic (SPENC1 kek / SPENC2 direct key via `DIRECT_EC_PRIVATE_KEY`), ffprobes, writes metadata, completes. Compose/mix jobs read direct objects the same way.
+- Requirements: `DIRECT_EC_PRIVATE_KEY` on api + media-worker + produce-worker (compose appenv).
+
+### 10.8 Files direct-to-R2 + media viewer
+- `GET /files/direct/config`, `POST /files/direct/init|complete`, `POST /files/:id/direct-download` (presigned GET + CEK ticket; the browser decrypts — the server never streams direct/ payloads).
+- Viewer suite: image lightbox (zoom/pan/rotate + filmstrip), brand video player (scrubber/buffered/volume/speed/PiP/fullscreen + keyboard), image EDITOR (crop with aspect presets, rotate 90s, flip H/V, brightness/contrast/saturation — saves as a NEW library file), video TRIM (in/out → the cut renders into the Video library via the assemble lane; the original is never modified), PDF (native iframe), text (+copy), HTML (sandboxed `allow-scripts` run + source toggle).
+- Thumbnails decrypt client-side; video stills are captured in-browser. Session cache dedupes decryption per item.
+- Browser memory caps the direct path at 512 MiB (sealing holds plaintext + frame); larger files fall back to the server path (Cloudflare-capped ~100 MB) until multipart lands.
+
+### 10.9 Multi-file upload queues
+- Both dropzones accept multiple files: sequential queue, per-file status (queued / % / done / failed), one failure never aborts the queue.
+- Video per-file transport: direct (when enabled, ≤512 MiB) → chunked (>10 MiB) → whole-body (≤10 MiB). Files per-file transport: direct (when enabled, ≤512 MiB) → server multipart.
+

 - Files group upload cap: **2 GiB** (was 20 MiB).

The sliders rendered dead when the video's duration hadn't loaded into
state (max=0). Duration discovery now polls loadedmetadata/durationchange
until it lands, the sliders stay disabled with a reading note until then,
and dragging either handle seeks the preview. Cuts are auto-versioned
(v2, v3… after the original v1) by counting same-source names in the
library — a cut always creates a new clip, never touches the original.

Subject: [PATCH 32/42] fix: jobless video assets no longer 500 the library
 click
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Legacy/edge-case video_assets rows without a processing job threw 'has no
processing job' from getVideoStatus — the library detail click 500ed.
VideoStatus.processingJob is now nullable end to end (api type, DTO, web
consumers null-guarded); a jobless asset renders as queued.

Subject: [PATCH 33/42] feat: video uploads up to 20 GiB via the chunked path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The dropzone rejected >2 GiB client-side while the chunked ingest allows
100 GiB server-side. Note: chunked reassembly + seal holds ~2x the file in
api RAM, so the practical ceiling on the current box is ~8-10 GiB — the
multipart-direct build removes that ceiling.

+# Spec: progressive playback for encrypted media (the "decrypting…" lag fix)
+
+## Problem
+Playing a Files video (SPENC2, client-sealed) waits for the WHOLE sealed file to
+download + decrypt before the first frame — length-dependent, brutal for 1-2 GB.
+
+## Why it's fixable cleanly
+SPENC2 frames are already stored as INDEPENDENT 10 MiB AES-GCM segments
+(header 135 B + per-segment 4+12+ctLen). Every segment decrypts on its own,
+so any plaintext range can be served by fetching + decrypting only the
+covering segments. No re-encryption, no format change.
+
+## Design
+1. API: `GET /files/:id/range?offset=N&length=M` (auth = download route;
+   direct/ objects only) → decrypts just the covering segments via
+   `S3Storage.readDirectRange` (ranged R2 GET covering the needed segments,
+   CEK unwrap from the same fetch, per-segment GCM), returns the plaintext
+   slice + headers: X-Total-Size, X-Segment-Bytes. 16 MiB per-request cap.
+2. Player integration (no Service Worker, no MSE): progressive blob —
+   fetch [0, 16 MiB) → objectURL → play immediately (our encodes are
+   +faststart, so a truncated mp4 plays head-first); background-fetch the
+   remaining chunks, appending; when playback nears the fetched edge or the
+   user seeks past it, await the covering chunk before continuing. On full
+   fetch: swap in the complete blob (scrub-anywhere).
+3. SPENC1 (server-sealed legacy): the single-stream GCM cannot be sliced —
+   keep the whole-file fetch (these are the small/older items; new uploads
+   are all SPENC2).
+
+## Non-goals / later
+- True MSE/fMP4 streaming with a Service Worker (better scrub UX, bigger build)
+- Audio file streaming (same endpoint serves it; the <audio> path is trivial)
+
+## Effort
+API endpoint + segment math: ~80 lines + tests. Player progressive fetcher:
+~60 lines in video-player/viewer. Total: half a session.
+
+---
+
+# Appendix: compute fabric design (2026-10-17)
+
+## Tiers
+1. **Shared worker (moxexleyhp1)** — the operator's box: 3090 CUDA (transcription sidecar live),
+   NVENC + QuickSync transcodes. Serves ALL collectives as baseline capacity.
+2. **Collective-owned workers** — a collective registers additional boxes via the hub
+   (collective-scoped worker token + Windows downloader + setup/connection instructions).
+   Those pull only that collective's jobs — increasing its compute without touching others.
+3. **LLM engines** — collectives (or the operator) register LiteLLM/OpenAI-compatible endpoints
+   as inference providers (per-collective model routing: a collective's AI features point at its
+   own engines first, hub defaults second).
+
+## Building blocks (when implemented)
+- worker_registrations table: workspace_id (NULL = shared), type (transcode | llm),
+  token_hash, endpoint_url / capabilities, last_seen_at, created_by
+- Poll/claim protocol scoped per registration (the produce_job_claim lane pattern extends)
+- Windows downloader + PowerShell installer + connection instructions (the ipfs3 failover
+  pattern: token + instructions served from the collective's Workers settings page)
+- LLM engine registrations join the model routing for AI features (transcription, captions,
+  search embeddings)

From the logic audit (HEAD 04f5f7e):
- P0 CORS: enableCors methods lacked PUT — browsers could not chunk-upload
  at all (cross-origin preflight refused)
- P0 chunked: validateUpload enforced the 2 GiB whole-body cap on chunked
  completes, so every >2 GiB chunked upload failed after full upload
- P1 presignPut: the SDK's flexible-checksum default added an
  x-amz-checksum-crc32 header browsers cannot reproduce; S3Client now uses
  requestChecksumCalculation WHEN_REQUIRED
- P1 refresh rotation race: concurrent refreshes both succeeded (consume
  ignored rowCount) forking the token family; consume now returns whether
  it won and the loser revokes the chain
- P2 logout: awaits the revocation and ignores missing/forged bearers

Subject: [PATCH 37/42] fix(video): logo overlays must belong to the workspace;
 drop debug stderr

- produceVideo checks every logo overlay key against the workspace's
  media_assets, group_assets or branding logo before queueing; a
  well-formed content address alone no longer suffices.
- Remove MEDIA_DEBUG_STDERR=1 from the production compose: it wrote raw
  ffmpeg stderr to an unrotated file, bypassing redaction.

Subject: [PATCH 38/42] feat: wire the Instagram connector into connect and
 publishing

The Instagram connector existed but was never registered, so Channels showed
it as "provider unavailable" and publishing could not resolve it.

- Register createInstagramConnector in the connections registry and the
  publishing registry; add the connector-runtime publishing policy
  (idempotency "none": media_publish has no key, never replay).
- The Facebook app credentials identify the Hub, not a collective: read them
  only from INSTAGRAM_CLIENT_ID / INSTAGRAM_CLIENT_SECRET. Drop the
  clientId/clientSecret connect fields and stop copying the app secret into
  each connection's vault entry. The provider is connectable only when both
  are set (connectEnabled + connectNote).
- Fail the connect when several Instagram accounts are granted instead of
  silently publishing as the first Page's account.
- Fix the connector package's pre-existing lint errors (it now ships in api).
- Tests: contract cases for env-only credentials and the multi-account
  refusal; connections integration case for provider gating and the
  Facebook dialog redirect.
- docs/oauth-connect.md: Instagram setup, callback URI and limits.

Not in this change: publishing images needs a public plaintext JPEG URL that
Meta downloads, and storage is client-side encrypted, so presigned S3 URLs
cannot serve it. Until a short-lived media endpoint exists, publishing to
Instagram fails with an explicit error. Token refresh via ig_refresh_token
on graph.facebook.com also needs checking against Facebook Login tokens.

 An instance administrator can enable a compatible OAuth bridge, then configure the two paths above. Its authorize endpoint must preserve `state`, register/validate the redirect URI, support `response_type=code` and S256 PKCE, and redirect back with a one-use code. Its token endpoint must validate `client_id`, `client_secret`, `redirect_uri`, `code`, and `code_verifier`, returning **actual PeerTube API** `access_token` and `refresh_token` values. Identity, refresh, and revoke then use PeerTube's native `/api/v1/users/me`, `/api/v1/users/token`, and `/api/v1/users/revoke-token` endpoints. These settings do not add an authorization-code grant to a stock instance, and an OIDC identity token alone is insufficient. The mock integration test proves this adapter contract; no third-party bridge is included in this change.
 
+### Instagram
+
+Instagram connects through Facebook Login against the Hub's own Facebook app. The App ID and App Secret identify the Hub, not a collective: they are read only from `INSTAGRAM_CLIENT_ID` / `INSTAGRAM_CLIENT_SECRET`, never entered on the connect form and never written to the vault or the pending store. In the Facebook app, add the product *Facebook Login for Business* and register the exact `CONNECTIONS_CALLBACK_URL` (default `${API_URL}/connections/callback`) as a Valid OAuth Redirect URI.
+
+Each person connects their own account through Meta's consent dialog; the Hub keeps the resulting long-lived token encrypted per connection. Requirements per account: an Instagram **Business or Creator** account linked to a Facebook Page, and — while the app is in Development mode — a Tester role on the app. Grant exactly one Instagram account in the dialog: when several are granted the connect fails instead of guessing which one to publish as. Public use needs Meta App Review for `instagram_basic`, `instagram_content_publish` and `pages_show_list`.
+
+Limitations: Instagram has no text-only posts and no binary upload — Meta downloads each JPEG from a public https URL. Media storage is client-side encrypted, so S3 presigned URLs cannot serve it; publishing images requires a short-lived plaintext media endpoint that is not part of this change. Until then publishing to Instagram fails with an explicit error. Stories are not publishable through the API; Meta caps API publishing at 25 posts per rolling 24 h per account.
+
 ### Telegram
 
 Create a bot in BotFather and enter its bot token. The connector validates it with `getMe`, then stores the token through the same encrypted vault envelope as OAuth credentials. Optionally supply a chat/channel ID (`@channel` or a numeric chat ID); add the bot to the target and grant any necessary posting rights. Identity health confirms token validity, not permission to publish to every chat. Reconnect accepts a replacement bot token for the same bot and rotates the credential row in place. Telegram's Bot API cannot revoke its own bot token: Remove clears local authorization; revoke/rotate the token through BotFather when needed.

From the hacklab/T-HUB fork (diverged at a6843e9):
- 046_file_folders: folder trees (group + personal scope, RLS forced,
  workspace-immutability trigger) + created_by on chat_media_archive
- Instagram connector wired into connect + publishing
- outreach contacts: per-collective DM tracking (todo/sent/replied/declined),
  RLS forced, role-scoped permissions, audit without message text,
  migration renumbered 041→047
- FORCE row-level security on media_assets
The J1 api agent's folder service/controller work continues separately.

+# Native Windows transcode worker: manual checks on moxexleyhp1
+
+Run these commands in **Windows PowerShell**, using Windows Python 3.9+ and
+the existing WinGet ffmpeg on PATH. Keep this Windows account logged on.
+
+## Install
+
+1. Open PowerShell in the Windows checkout of this repository.
+2. Run:
+
+   ```powershell
+   powershell.exe -NoProfile -ExecutionPolicy Bypass -File .\apps\media-worker\scripts\install-windows-worker.ps1
+   Get-ScheduledTask -TaskName 'TMBH-TranscodeWorker'
+   ```
+
+   If Python is not found, add `-PythonExe 'C:\path\to\python.exe'` to the
+   installer command. The optional `-JobRoot` changes all three queue folders.
+   The task starts immediately, polls every 5 seconds, starts at logon, and
+   is triggered every 5 minutes to recover if it exits. Duplicate starts are
+   ignored; a per-inbox file lock also prevents competing manual workers.
+   The installer can be rerun to update the task.
+
+3. Verify `inbox`, `done`, and `failed` exist under `C:\transcode-jobs`.
+   Generate a short input with video and audio:
+
+   ```powershell
+   ffmpeg -hide_banner -n -f lavfi -i 'testsrc2=size=1280x720:rate=30' -f lavfi -i 'sine=frequency=440:sample_rate=48000' -t 10 -c:v mpeg4 -q:v 3 -c:a aac 'C:\transcode-jobs\sample.mp4'
+   if ($LASTEXITCODE -ne 0) { throw 'Sample generation failed' }
+   ```
+
+   Use fresh output/job names when repeating these checks. Existing output
+   files are rejected and preserved. Relative input/output paths resolve
+   against the inbox; absolute Windows paths are recommended. Outputs use
+   their extension to choose the container. Jobs run sequentially.
+
+## NVENC H.264 on the RTX 3090
+
+- [ ] Publish a job atomically, so polling never reads a partly written JSON:
+
+  ```powershell
+  @{ input = 'C:\transcode-jobs\sample.mp4'; output = 'C:\transcode-jobs\nvenc.mp4'; preset = 'nvenc_h264'; crf = 23 } | ConvertTo-Json | Set-Content -Encoding UTF8 'C:\transcode-jobs\inbox\nvenc.tmp'
+  Move-Item 'C:\transcode-jobs\inbox\nvenc.tmp' 'C:\transcode-jobs\inbox\nvenc.json'
+  ```
+
+- [ ] Within a poll interval plus encode time, `done\nvenc.json` and a
+  playable, nonempty `C:\transcode-jobs\nvenc.mp4` exist; the inbox job is gone.
+- [ ] Inspect the output:
+
+  ```powershell
+  ffprobe -v error -show_entries stream=codec_name,codec_type -of json 'C:\transcode-jobs\nvenc.mp4'
+  ```
+
+  Expect H.264 video and AAC audio. While encoding, observe NVIDIA's **Video
+  Encode** graph in Task Manager (use a longer input if needed).
+- [ ] Repeat with `preset = 'nvenc_hevc'`, a new job name, and output
+  `nvenc-hevc.mp4`; expect HEVC video and AAC audio. If the installed ffmpeg
+  lacks `hevc_nvenc`, expect a failed job with encoder diagnostics instead.
+
+## Intel QuickSync H.264
+
+- [ ] Publish a QSV job, omitting `crf` to exercise the default quality of 23:
+
+  ```powershell
+  @{ input = 'C:\transcode-jobs\sample.mp4'; output = 'C:\transcode-jobs\qsv.mp4'; preset = 'qsv_h264' } | ConvertTo-Json | Set-Content -Encoding UTF8 'C:\transcode-jobs\inbox\qsv.tmp'
+  Move-Item 'C:\transcode-jobs\inbox\qsv.tmp' 'C:\transcode-jobs\inbox\qsv.json'
+  ```
+
+- [ ] Verify `done\qsv.json`, playable `qsv.mp4`, and H.264/AAC streams using
+  the ffprobe command above with the QSV output path.
+- [ ] Observe the Intel GPU's **Video Encode** graph during the job. Encoder
+  initialization failures belong in `failed` and must include ffmpeg's error;
+  the worker never retries with a software video encoder.
+
+## Failure and continued polling
+
+- [ ] Queue a missing input:
+
+  ```powershell
+  @{ input = 'C:\transcode-jobs\does-not-exist.mp4'; output = 'C:\transcode-jobs\must-not-exist.mp4'; preset = 'nvenc_h264' } | ConvertTo-Json | Set-Content -Encoding UTF8 'C:\transcode-jobs\inbox\missing.tmp'
+  Move-Item 'C:\transcode-jobs\inbox\missing.tmp' 'C:\transcode-jobs\inbox\missing.json'
+  ```
+
+- [ ] Expect `failed\missing.json` and `failed\missing.json.err`, mentioning
+  the missing input. No output is created and the inbox job is gone.
+- [ ] Queue a text file as input with a valid preset. Expect a failed JSON
+  and `.json.err` containing ffmpeg's nonzero exit code and stderr. No final
+  output or `.part.mp4` file should remain.
+- [ ] Queue malformed JSON, an unknown preset, and a string `crf` in separate
+  jobs. Each must move to `failed` with a useful `.err` file.
+- [ ] Queue an existing output path (e.g. the sample). Expect failure without
+  changing the existing file.
+- [ ] Queue another valid job with a fresh output name; verify completion
+  after the failed jobs. Reuse a failed job filename and verify both archived
+  jobs and their errors survive (a UUID is added on name collisions).
+
+## Task lifecycle and foreground diagnostics
+
+- [ ] Log off and back on; verify the task runs. Stop the task, then verify
+  the repeating trigger starts it again within 5 minutes.
+- [ ] For foreground diagnostics or a single pass, stop **and disable** the
+  task first so its repeating trigger cannot race the manual run:
+
+  ```powershell
+  Disable-ScheduledTask -TaskName 'TMBH-TranscodeWorker'
+  Stop-ScheduledTask -TaskName 'TMBH-TranscodeWorker'
+  python .\apps\media-worker\scripts\windows-transcode-worker.py --once

+  Omit `--once` for continuous foreground polling; press Ctrl+C to stop.
+  A second worker on the same inbox must exit without executing jobs.
+  Force-stopping during an encode can leave a hidden `.part` output; remove
+  it after confirming no ffmpeg process is using it. Its job stays in the
+  inbox for retry. Normal encode failures clean up the temporary output.

Adapted from the T-HUB fork's README (which documented our own deployment
better than our README did): the three flows (one account / shared accounts /
technical half) as mermaid diagrams updated to today's reality (SPENC1/SPENC2
sealed R2, produce-worker lanes, direct-to-R2), the per-network connect/publish
status table, the outreach panel's no-send rationale, hardware/bandwidth
requirements, the network/ports exposure table, security practices and the
monitoring signal table.

 - **Archive** — content-addressed encrypted S3, dedup, full-text search, CSV/JSON export. Deleted platform content stays citable.
 - **Analytics** — month-partitioned snapshots, current + previous month with deltas, per-provider breakdown.
 
+## Architecture
+
+Three flows explain the whole system.
+
+### 1. One account
+
+One person connects a collective's account once. From then on: draft, someone
+approves, the Hub publishes. The social network's password never passes through
+the Hub — the network returns a token and the Hub stores it encrypted.
+
+```mermaid
+flowchart LR
+    P([Person]) -->|1. Connect| H[Hub]
+    H -->|2. Permission screen| R[(Social network)]
+    R -->|3. Token| H
+    P -->|4. Drafts| H
+    H -->|5. Approval| A([Another crew member])
+    A -->|6. Sign-off| H
+    H -->|7. Publishes on time| R
+```
+
+### 2. Several shared accounts
+
+Each collective has its own accounts and approval rules. A draft can go to
+several accounts at once: the Hub creates one copy per destination and each
+passes its own account rule (automatic, one person, majority or consensus).
+Anything meant for the whole network rises to the parent collective's queue.
+
+```mermaid
+flowchart TB
+    subgraph TTS[NETWORK QUEUE]
+        Q[Shared queue] --> IG1[Instagram international]
+        Q --> M1[Mastodon @network]

+    SUB -->|Uploads to A| D
+    IG2 -.->|Rule: 2 approvals| G{{Approval}}
+    M2 -.->|Rule: automatic| G
+```
+
+### 3. The technical half
+
+The web only talks to the API. The API keeps state in Postgres with
+per-collective row-level security, credentials live in an encrypted vault, and
+scheduled publishing runs through the scheduler with Temporal. Each network is
+a connector; outside the connectors there is no code that distinguishes
+networks. Media bytes are end-to-end encrypted (SPENC1 server-sealed,
+SPENC2 browser-sealed) in content-addressed R2 storage; heavy processing runs
+in workers that pull sealed jobs — the api box never touches plaintext.

+
+Connecting an account (OAuth with one-time `state` and PKCE where the network
+supports it):
+
+1. `POST /connections/authorize`: the API stores the request state encrypted in
+   Redis and returns the network's URL.
+2. The person accepts on the network, which returns to
+   `GET /connections/callback`.
+3. The API checks `state`, cookie and permissions, redeems the code and stores
+   the token in the vault.
+
+## Network status
+
+| Network | Connect | Publish | Notes |
+|---|---|---|---|
+| Mastodon | Yes | Text | No server keys; each account registers the app on its instance. |
+| Telegram | Yes | Text | Bot token from BotFather. |
+| Instagram | Yes, with `INSTAGRAM_CLIENT_ID/SECRET` | Not yet | Meta fetches the image from a public URL and media are encrypted: a temporary endpoint is pending. See [docs/oauth-connect.md](docs/oauth-connect.md). |
+| PeerTube | No | Live only | The OAuth bridge on tube.occupymedia.cc is pending. |
+| X | No | No | No connector. Paid per-use API. |
+| TikTok | No | No | Out of scope: the API requires an audit; without it only private publishing. |
+
+## Outreach (hand-written DMs)
+
+A list of public accounts (artists, collectives, media) to write to privately
+asking for amplification. Each contact has its drafted message, fillable from a
+template (`{name}`, `{handle}`), marked sent / replied / declined. CSV import:
+
+```
+name,platform,handle,profileUrl,category,language
+Climáximo,bluesky,climaximopt.bsky.social,https://bsky.app/profile/climaximopt.bsky.social,climate,pt
+```
+
+The Hub **does not send** the messages. "Copy & open profile" copies the text
+and opens the profile; the person pastes and sends it from the network's own
+DM box. Reasons:
+
+| Network | Open a DM via API | Problem |
+|---|---|---|
+| Instagram | No | The API only allows replying to whoever wrote you in the last 24 h. |
+| X | Yes, paid | Mass DMs to strangers break automation rules: suspension. |
+| Mastodon | Yes (private mention) | Instances mute or block accounts doing it in bulk; the whole instance can suffer. |
+| Bluesky | Yes | Same spam criteria; stranger chats are usually closed. |
+
+The screen counter warns from 20 first messages per day per collective.
+Spread them across people and days, and personalise each one.
+
+## Requirements
+
+Measured on the current deployment. Media goes to R2, so the disk does not
+grow with videos.
+
+| Tier | CPU | RAM | Disk | For |
+|---|---|---|---|---|
+| Minimum | 4 vCPU | 8 GB | 160 GB SSD | The whole stack, transcoding off-box |
+| Recommended | 8 vCPU | 16 GB | 240 GB SSD | Livestreams, on-box transcoding, Collabora |
+| Render node (optional) | 4+ cores or a GPU with NVENC | 8 GB | 50 GB | Joins over Tailscale; never holds keys |
+
+Real usage today: ~2.6 GB of RAM across all services.
+
+Bandwidth:
+
+| Use | Needed |
+|---|---|
+| Panel, publishing, network APIs | < 1 Mbps sustained |
+| One outgoing live (1080p30 to PeerTube) | 6 Mbps upload per live; 3 Mbps at 720p |
+| Viewers | Served by Cloudflare from the HLS cache; the origin does not scale with the audience |
+| Video uploads | Bursts as fast as the line allows; 100 GiB per file via chunked ingest |
+
+## Network and ports
+
+Inbound from the internet: **none direct**. Everything enters through the
+Cloudflare tunnel (with an ingress failover to a standby proxy); the edge
+nginx only accepts Cloudflare ranges on 80/443.
+
+| Port | Service | Expose to |
+|---|---|---|
+| 443/tcp | Edge nginx | Cloudflare ranges only |
+| 80/tcp | Edge nginx (redirect) | Cloudflare ranges only |
+| 3000/tcp | API | 127.0.0.1 only |
+| 3001/tcp | Web | 127.0.0.1 only |
+| 9000/tcp | PeerTube | 127.0.0.1 or Tailscale |
+| 1935/tcp | PeerTube RTMP | Tailscale only (media worker) |
+| 6167/tcp | Matrix (conduwuit) | 127.0.0.1 |
+| 9200, 9980/tcp | oCIS, Collabora | 127.0.0.1 |
+| 5432, 6379, 7233 | Postgres, Redis, Temporal | Never outside the Docker network |
+
+Required egress: 443/tcp to the networks' APIs and to R2, 7844/tcp+udp for
+`cloudflared`, 41641/udp for Tailscale.
+
+Docker publishes ports bypassing ufw. To close them: publish on
+`127.0.0.1:PORT`, on the Tailscale IP, or add rules to the `DOCKER-USER` chain.
+
+## Security and monitoring
+
+Practices for any deployment. Report security failures privately to the
+maintainers — never in public issues.
+
+- **Invite-only registration.** Open registration hands anyone a collective of their own with Owner rights on it.
+- **One secret per service.** The web and workers never need `SUPERPOSTER_KEK`, `S3_KEK` or `SESSION_SECRET`. Different keys for the vault and for media.
+- **FFmpeg always sandboxed** (`NODE_ENV=production`, `MEDIA_SANDBOX=on`), no network, no inherited environment variables.
+- **Headers**: strict CSP, HSTS, `X-Content-Type-Options`, `Referrer-Policy` on web and API.
+- **Request limits** on `/auth/*`, invitations, OIDC and public uploads, keyed by `CF-Connecting-IP`.
+- **Metadata out**: strip EXIF/GPS from photos and videos before storing or publishing.
+- **Encrypted backups** (`age` or GPG) kept off-machine; test the restore.
+- **Tamper-proof audit**: revoke `UPDATE`/`DELETE` on `audit_log` from the `sp_app` role and anchor the chain head off-box.
+
+What to watch (Prometheus + Grafana ship in `infra/`; Grafana never anonymous):
+
+| Signal | Alert if |
+|---|---|
+| `401`/`403` on `/auth/login` per IP | > 20 in 5 min |
+| New registrations / redeemed invitations | Anything unplanned |
+| `audit_log` events: `member.*`, `connection.removed`, `group.deleted`, `outreach.removed` | Spikes or odd actors |
+| `connections` in `needs_credentials` state | Any: token revoked or expired |
+| API 5xx rate | > 1 % over 5 min |
+| API and worker memory | > 80 % |
+| Publishing queue `failed`/`unknown` | Any |

Subject: [PATCH 41/42] =?UTF-8?q?fix:=20oidc=20hardening=20=E2=80=94=20sid?=
 =?UTF-8?q?-less=20consent=20refused,=20rotation=20race=20closed,=20iss=20?=
 =?UTF-8?q?on=20errors,=20logout=20honesty?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

From the logic audit:
- consent rejects sid-less bearers and requires a LIVE hub session
  (sessionAlive) before minting codes — a logged-out bearer can no longer
  mint downstream tokens inside its TTL
- refresh rotation race closed: consume returns whether THIS call won;
  the loser revokes the family (reuse detection now holds under
  concurrency)
- error redirects carry iss (RFC 9207) on error responses too
- logout awaits the revocation and no longer returns ok for missing or
  forged bearers

Subject: [PATCH 42/42] fix: connector-instagram entrypoint must be compiled
 dist
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The T-HUB package pointed main at src/index.ts — node 22 type-stripping
executed it at runtime and crashed the api on the parameter properties
(authorizationUrl/connectionId). main now targets dist/index.js like every
other connector package; tsconfig copied from connector-mastodon.
